DETAILED DESCRIPTION
[0063] FIG. 1 shows a schematic, perspective view of a scaffolding section 100 having two different scaffolding systems 2 and 3. The scaffolding section 100 shown here comprises a first scaffolding system 1 extending in the vertical direction and a second scaffolding system 3 represented by two horizontal supports 31 running horizontally. The first scaffolding system 2 is a frame scaffolding or system scaffolding. It is easy to see that the first scaffolding system 2 has regularly arranged, repeating scaffolding elements. The first scaffolding system 2 is constructed as a modular system from which various components or scaffolding elements can be combined into scaffolding sections of different shapes. The first scaffolding system 2 has a plurality of grid dimensions that are repeated in the scaffolding section. It is also said that the scaffolding is built up in a grid. Such a grid dimension extends, for example, between the crossbars running horizontally in the illustration, six of which are arranged on the side of the scaffolding section of the 100 that points to the front left. The first scaffolding system 2 has further grid dimensions, for example the length and width of the shown scaffolding section 100. In the vertical direction, a plurality of vertical posts 21 are arranged in the shown scaffolding section 100. The two horizontal supports 31 belong to a second scaffolding system 3. These horizontal supports of the second scaffolding system 3 are significantly more stable than the elements of the first scaffolding system 2. Typically, the second scaffolding system 3 is used to accommodate higher loads or to span greater distances. In the scaffolding section 100 shown, the first scaffolding system 2 and the second scaffolding system 3 are connected to one another by a total of four connecting components 1. The connecting components 1 form junction points between the two scaffolding systems 2 and 3. As can be clearly seen in the illustration in FIG. 1, the connecting components 1 are integrated into the grid of both scaffolding systems 2 and 3. This means that both scaffolding systems 2 and 3 can be built further in their own grid via the connection point formed by the connecting component 1. As a result, the modular principle of both scaffolding systems 2 and 3 is retained, which is very advantageous for speedy erection and dismantling and for ensuring the load-bearing capacity of the scaffolding section 100. Details on the connecting component 1 and its connection to the two scaffolding systems 2 and 3 can be seen in the following illustrations and are described accordingly.
[0064] FIG. 2 shows a perspective view of a first embodiment of a connecting component 1 according to the invention. The connecting component 1 shown has the following three main regions arranged from top to bottom in one direction in the illustration: The first connection region 11 is arranged at the very top. Adjacent below the first connection region 11 is the attachment region 12. Again below the attachment region 12 is a second connection region 13. The first connection region 11 provides one or more interfaces for connection to a first scaffolding system 2. The first connection region 11 extends along a longitudinal axis LA. The first connection region 11 comprises a shaft 111, which is formed here by a cylindrical tube section. A connecting disk 15 is arranged on the outer peripheral surface of the shaft 111. The connecting disk 15 has a planar connection surface 151 oriented upward in the illustration. A plurality of connecting recesses 152 which penetrate through the connecting disk 15 are arranged here in the connection surface 151. The connecting disk 15 is provided for connection to the scaffolding elements of the first scaffolding system 2. The connecting disk 15 is based on a connecting disk which is used in the first scaffolding system 2 as an interface between the scaffolding elements. Inside the shaft 111 is the receptacle 1111. The receptacle 1111 is formed here by the hollow interior of the shaft 111 and extends through the entire shaft along the longitudinal axis LA. The receptacle 1111 here has a circular cross section. Scaffolding elements of the first scaffolding system 2 can be inserted into the receptacle 1111 in order to create a positive-locking connection to the connecting component 1. A staking hole 14 is arranged in the shaft 111 between the connecting disk 15 and the attachment region 12. A pinning element can be inserted through this staking hole 14, which then penetrates the wall of the shaft and a recess in a scaffolding element of the first scaffolding system 2 introduced into the receptacle 1111. A scaffolding element of the first scaffolding system 2 can be fixed by means of such a staking to the connecting component 1 in a direction parallel to the longitudinal axis LA. The second connection region 13 is arranged on the side of the connecting component 1 which is at the bottom in the illustration. The second connection region 13 is also used to connect the connecting component 1 to the first scaffolding system 2. The second connection region 13 is also formed to a large extent by a cylindrical tube section. Inside, the second connection region also has a receptacle 131 which is accessible from below and which is arranged in the shaft 132. The receptacle 131 has a diameter identical to that of the receptacle 1111, likewise extends along the longitudinal axis LA and is positioned coaxially with the receptacle 1111. In the illustrated embodiment, it is possible to produce a part of the first connection region 11 and the second connection region 13 from a common, continuous tubular section. Also in the wall of the second connection region 13 is a staking hole 14 which, like the staking hole 14 in the first connection region 11, serves to connect or secure with a scaffolding element of the first scaffolding system 2. In the illustrated embodiment, a part of the second connection region 13 is arranged inside the attachment region 12. This results overall in a compact and stable design of the connecting component 1. The attachment region 12 is arranged in the central region of the connecting component 1 and serves as an interface for connection to a second scaffolding system 3. The attachment region 12 has an abutment 121 on its upward-facing side. In the illustrated embodiment, this abutment 121 is formed by a flat, rectangular cover plate 1211 and a partial region of the two insertion plates 123. The cover plate 1211 is directly adjacent to the shaft 111 of the first connection region 11. The cover plate 1211 is oriented with its largest surface perpendicular to the longitudinal axis LA. In a top view from the direction of the longitudinal axis LA, the cover plate 1211 is rectangular, the longer side of the rectangle extending in the same direction in which the two insertion plates 123 are arranged radially with respect to the longitudinal axis LA. The upper partial regions of the two insertion plates 123 also belong to the abutment. Each insertion plate 123 is T-shaped in a top view. The upper bar of the T belongs to abutment 121. Planar surfaces are arranged on the side of this bar of the T-shaped insertion plates 123 that points downward in the illustration and together form the first bearing surface 121a of the abutment 121 here. When the connecting component 1 is connected to the second scaffolding system 3, the first bearing surface 121a rests on a scaffolding element and forms an abutment for positioning the connecting component 1 relative to the second scaffolding system 3. On the side of the cover plate 1211 pointing downward in the illustration, the second bearing surface 121b of the abutment 121 is arranged in the region which projects over the two insertion plates 123. In the case of a connection to the second scaffolding system 3, in the illustrated embodiment either the first bearing surface 121a or the second bearing surface 121b can be placed on a scaffolding element of the second scaffolding system 3. Which of the two bearing surfaces 121a or 121b is actually used depends on which of the two insertion interfaces 1221 or 1222 described below is used for the connection.
[0065] In the embodiment shown in FIG. 2, the attachment region 12 comprises two insertion interfaces 1221 and 1222. Parts of these insertion interfaces 1221 and 1222 rest against one or more scaffolding elements of this second scaffolding section 3 when the connecting component 1 is connected to the second scaffolding section 3. The first insertion interface 1221 has a partial region on two opposite sides of the longitudinal axis LA. The first insertion interface 1221 here comprises two first abutment surfaces 1221a and 1221b which are oriented parallel to one another and point to the front right and rear left in the illustration. The two first abutment surfaces 1221a and 1221b are here formed jointly by the two insertion plates 123. As already described above, the two insertion plates 123 are T-shaped in the illustrated embodiment. Each insertion plate 123 has a mounting surface 123a facing radially inward in the direction of the longitudinal axis LA. Each insertion plate 123 is attached to the inner region of the attachment region 12 via the mounting surface 123a. In the illustrated embodiment, this inner region is formed by a tube section. The two insertion plates 123 are fastened here with a welded connection to the tubular section arranged in the interior. Adjacent to the mounting surface 123a, a narrow edge runs all the way around the insertion plate 123. This edge forms the edge region 123b. Partial regions of the first two abutment surfaces 1221a and 1221b are arranged on partial regions of this edge region 123b. In other words, the first of the first abutment surfaces 1221a is formed jointly by partial regions of the edge region 123b of the two insertion plates 123 pointing forward to the right. The second of the first abutment surfaces 1221b is formed jointly by partial regions of the edge region 123b of the two insertion plates 123 pointing to the rear left. Partial regions of the two abutment surfaces 1221a and 1221b are thus positioned on both sides of the longitudinal axis LA, spaced apart from one another on both sides of the tube section arranged in the interior. As a result, the two first abutment surfaces 1221a and 1221b together make up a spatially distributed abutment surface which, when connected to the second scaffolding system 3, allows good force and torque transmission between the connecting component 1 and the second scaffolding system 3. When the first insertion interface 1221 and the two first abutment surfaces 1221a and 1221b are used, the first bearing surface 121a which is arranged directly adjacent to and bordering the first abutment surfaces 1221a and 1221b on the insertion plates 123 is used to rest the connecting component 1. Between the two insertion plates 123 in the tube section arranged between them are two securing recesses 12211 which belong to the first insertion interface 1221 and are arranged one above the other. The two securing recesses 12211 penetrate the entire insertion region 122 and can be used for the positive-locking connection or securing of the connecting component 1 to the second scaffolding system 3. The attachment region 12 includes a second insertion interface 1222. This second insertion interface 1222 has two second abutment surfaces 1222a and 1222b. These two second abutment surfaces 1222a and 1222b point to the front left and to the rear right in the illustration and are each arranged on a side of an insertion plate 123 opposite the mounting surface 123a. The distance between the two first abutment surfaces 1221a and 1221b differs from the distance between the two second abutment surfaces 1222a and 1222b here. Due to these different distances, the two insertion interfaces in 1221 and 1222 are dimensioned differently and can thus be used as connection interfaces for connection to differently dimensioned scaffolding elements of the second scaffolding system 3. It is advantageous here that the two insertion interfaces 1221 and 1222 are already operational and offset 90° and are firmly arranged on the connecting component 1. In the construction of a scaffolding section 100, the connecting component 1 can simply be rotated about the longitudinal axis LA in order to select the appropriate insertion interface 1221 or 1222 for the connection. The connecting component 1 in the illustrated embodiment can thus be adapted very easily to different scaffolding elements of the second scaffolding system 3. At the same time, the illustrated arrangement of components with the two T-shaped insertion plates 123 connected to a tube section is very compact and stable, as a result of which high load-bearing capacities of the connecting component 1 are achieved. When using the second insertion interface 1222 and the two second abutment surfaces 1222a and 1222b, the second bearing surface 121b adjoining these two second abutment surfaces 1222a and 1222b is used for resting on the second scaffolding system 3. In the region of the second bearing surface 121b, the abutment 121 projects further in the radial direction over the longitudinal axis LA than in a direction 90° offset therefrom. The cover plate 1211 has its side that is longer in a top view from the direction of the longitudinal axis LA between the partial regions of the second bearing surface 121b. This ensures that in the region of the second insertion interface 1222 there is a sufficiently large overhang of the second bearing surface 121b over the two second abutment surfaces 1222a and 1222b. At the same time, the abutment 121 is prevented from overhanging or projecting unnecessarily in the region of the first insertion interface 1221 and the two first abutment surfaces 1221a and 1221b. A light and slim design of the connecting component 1 is thereby achieved. Due to the fact that the abutment 121 projects less radially to the longitudinal axis LA in the region of the first insertion interface 1221, the attachment region 12 is narrow enough in this direction to be inserted into a narrow grid dimension of the second scaffolding system 3 without causing collisions with elements of this second scaffolding system 3. The second insertion interface 1222 here comprises a securing recess 12211, which here penetrates both insertion plates 123 and extends at a right angle to the two second abutment surfaces 1222a and 1222b. In the illustrated embodiment, the cover plate 1211 of the abutment 121 is connected to the first connection region 11 and the two insertion plates 123 via welded joints, respectively. The shaft 111 of the first connection region 11, the inner region of the attachment region 12 arranged between the insertion plates 123 and the shaft 132 of the second connection region 13 are formed in the illustrated embodiment by a common, continuous tube section. This common tubular section has a constant internal cross section in its interior.
[0066] FIG. 3 shows a representation of a second embodiment of a connecting component 1 according to the invention in a) a side view, b) a top view and c) a perspective view. The second embodiment of a connecting component 1 shown in FIG. 3 differs from the first embodiment shown in FIG. 2 in the design of the attachment region 12. Unless otherwise described, reference is made to FIG. 2 and the associated description for details of the second embodiment. The first connection region 11 is identical to the first embodiment in FIG. 2. The second embodiment in FIG. 3 also has a second connection region 13, which is also designed almost identically to the first embodiment in FIG. 2. In addition, the second connection region 13 in FIG. 3 has a plurality of staking holes 14. The insertion region 122 of the attachment region 12 here also includes two insertion interfaces 1221 and 1222, which are provided as alternatives that can be selected for connecting the connecting component 1 to a scaffolding element of the second scaffolding system 3. The two insertion plates 123 of the illustrated embodiment differ in shape from the insertion plates 123 of the first embodiment. The two second abutment surfaces 1222a and 1222b are curved here and arranged symmetrically with respect to the longitudinal axis LA. The mounting surfaces 123a are also curved in the illustrated embodiment, as a result of which they rest, over a large surface, against the cylindrical tube section forming the interior of the attachment region 12. The two insertion plates 123 are connected to this cylindrical tube section by means of welded joints. The first insertion interface 1221 is also offset 90° in relation to the second insertion interface 1222 in a top view of the longitudinal axis LA. The two first abutment surfaces 1221a and 1221b are also formed here by the edge regions 123b of the two insertion plates 123. The edge regions 123b are also curved here in some regions. Both the first insertion interface 1221 and the second insertion interface 1222 have at least one securing recess 12211 that completely penetrates the attachment region 12. In this embodiment, a threading region 123c is placed in each of the two insertion plates 123. This threading region 123c is provided to facilitate the insertion of a staking element 33 into the securing recess 12211 of the second insertion interface 1222. In the top view b) shown in the center, the threading region 123c is removed from the insertion plate 123 in a semicircle. In the side view a) and the perspective view c), it can be seen that this shape acts like a chamfer or insertion bevel around the securing recess 12211. In a top view from the direction of the securing recess 12211, the threading region 123c is arranged coaxially with the central axis of the securing recess 12211. In addition, the threading region 123c, which represents an undercut in the insertion plate 123, can also be used for the positive-locking connection to a scaffolding element of the second scaffolding system 3. In the second embodiment shown in FIG. 3, the first bearing surface 121a and the second bearing surface 121b are both arranged on the cover plate 1211 of the abutment 121. Both bearing surfaces 121a and 121b are thus located in the same plane here. Also in the second embodiment, the distance between the two first abutment surfaces 1221a and 1221b differs from the distance between the two second abutment surfaces 1222a and 1222b.
[0067] Scaffolding sections 100 can be seen in each of the following drawings. In each of the scaffolding sections 100 in FIGS. 4 and 5, the first embodiment of a connecting component 1 from FIG. 2 is installed; in FIGS. 6 to 9, the second embodiment of a connecting component 2 from FIG. 3 is installed.
[0068] FIG. 4 shows a perspective view of a first embodiment of a scaffolding section 100 according to the invention. FIG. 4 corresponds to a partial region of the scaffolding section 100 from FIG. 1. A connecting component 1 according to the first embodiment can be seen approximately in the center of the illustrations. The first connection region 11 is connected to a scaffolding element of the first scaffolding system 2. The second connection region 13 is also connected to a scaffolding element of the first scaffolding system 2. In contrast, the attachment region 12 is connected to a scaffolding element of the second scaffolding system 3. For details which are covered in FIGS. 4 and 5 by scaffolding elements of the second scaffolding system 3, reference is made to FIG. 2 and the associated description.
[0069] The first connection region 11 pointing upward is connected to a vertical post 21 of the first scaffolding system 2 via an adapter piece 211. In this case, the adapter piece 211 comprises a projecting region which is introduced into the receptacle 1111 of the first connection region 11. A shoulder of the adapter piece 211 rests on the upper end face of the first connection region 11. The adapter piece 211 additionally has a further, upward-pointing, projecting region, which is inserted into the lower end of the vertical post 21. A shoulder is also arranged on the side facing the vertical post 21 on the adapter piece 211, on which shoulder the end face of the vertical post 21 rests. In the embodiment shown, force is transmitted in the vertical direction by forces being transmitted from the vertical post 21 to the connection region 11 via the two shoulders of the adapter piece 211. Alternatively, it is possible to arrange a projecting region directly on the vertical post 21, which is then inserted into the receptacle 1111. The visible height of the adapter piece 211 also allows the effective overall length of the connecting component 1 to be adjusted, as a result of which the connecting component 1 can be easily adapted to the grid dimension of different first scaffolding systems 2. A vertical post 21 is also connected to the second connection region 13 arranged below. Here, too, an adapter piece 211 is used for the connection. However, the adapter piece used in the second connection region 13 does not have any shoulders like the adapter piece 211 used in the first connection region 11. The adapter piece 211 inserted below is inserted both into the receptacle 131 in the second connection region and into the interior of the vertical post 21. The lower adapter piece 211 aligns the two components just with each other, so that their end faces rest directly on each other. Forces in the vertical direction are thus transmitted below directly between the end faces of the components. A small gap is drawn in the illustration to make the adapter piece visible. When used, this gap cannot be seen. The second scaffolding system 3 is represented here by a horizontal support 31. The second scaffolding system usually includes further scaffolding elements, which are not shown here. The horizontal support 31 comprises two support rails 31a and 31b, which are spaced apart and aligned parallel to one another. The two support rails 31a and 31b here have a C-shaped cross section and are oriented to one another in such a way that the long sides of the C are opposite one another. The two support rails 31a and 31b are positioned relative to one another by at least two spacers 34 (not shown), which are arranged between the two support rails 31a and 31b. The two support rails 31a and 31b have a plurality of recesses at which other elements can be connected to the horizontal support 31. Visible is a forward-facing receiving recess 32 which penetrates both support rails 31a and 31b and has a circular cross-section here. In the embodiment shown in FIG. 4, the connecting component 1 is connected to the horizontal support 31 via its first insertion interface 1221. To establish the connection, the insertion region 122 is inserted between the two support rails 31a and 31b until the first bearing surface 121a strikes and rests on top of the two support rails 31a and 31b. This striking marks the correct position of connecting component 1 relative to the horizontal support 31. In the inserted state, the two first abutment surfaces 1221a and 1221b are each in contact with an inwardly directed wall of one of the support rails 31a and 31b. There is thus a large overall bearing surface between the connecting component 1 and the horizontal support 31, which allows good force and torque transmission between the two components. In the position shown, a securing recess 12211 of the connecting component 1 is aligned with a receiving recess 32 in the horizontal support 31, so that the two components can be connected to one another via a staking element 33 in a positive-locking manner. Such a staking element 33 is shown in simplified form in FIG. 4 as a cylindrical pin. As can be seen in FIG. 4, the abutment 121 and the insertion region 122 do not project over the horizontal support 31 anywhere in the transverse direction. As a result, the attachment of further scaffolding elements to the horizontal support 31 is not impeded and the risk of injury to people is reduced.
[0070] FIG. 5 shows a perspective view of a second embodiment of a scaffolding section 100 according to the invention. Unless otherwise described, the second embodiment corresponds to the embodiment shown in FIG. 4 and described in relation thereto. The second embodiment in FIG. 5 comprises a larger dimensioned horizontal support 31 of a second scaffolding system 3, which is connected to the connecting component 1. This horizontal support 31 also includes two support rails 31a and 31b, which, however, are larger than in FIG. 4 and are also arranged at a greater distance from one another. For this reason, the connecting member 1, which is the same connecting member 1 as in FIG. 4, is connected in FIG. 5 to the horizontal support 31 via the second insertion interface 1222. Therefore, the two second abutment surfaces 1222a and 1222b bear against the inwardly facing surfaces of the two support rails 31a and 31b. The second bearing surface 121b, which is arranged at the bottom of the cover plate 1211, in this case rests on the upward-facing surfaces of the two support rails 31a and 31b. In FIG. 5, the second insertion interfaces 1222 and the two support rails 31a and 31b are positioned relative to one another such that the securing recess 12211 in the insertion region 122 is aligned with a receiving recess 32 in the horizontal support 31. Thus, in this case too, the connected components can be staked using a staking element 33. A direct comparison between FIG. 4 and FIG. 5 clearly shows that the connecting component 1 can be connected to two horizontal supports 31 of different dimensions by simply rotating it 90° about its longitudinal axis. The connecting component 1 can therefore be handled flexibly and nevertheless ensures a stable, safe and ergonomic connection to different horizontal supports 31 of a second scaffolding system 3.
[0071] FIGS. 6, 7, 8 and 9 each show scaffolding sections 100 which each comprise a connecting component 1 according to any of the second embodiment shown individually in FIG. 3. For the sake of simplicity, the connected scaffolding elements of the first scaffolding system 2 which are connected to the first connection region 11 and/or a second connection region 13 are not shown in these scaffolding sections 100. In FIGS. 6, 7, 8 and 9, the connection of the attachment region 12 to a horizontal support 31 is shown. For elements that are hidden in these views and therefore not shown, reference is made to FIG. 3 and the associated description.
[0072] FIG. 6 shows a side view of a third embodiment of a scaffolding section 100 according to the invention. FIG. 6 shows a side view in which a connecting component 1 is connected to a horizontal support 31 via its second insertion interface 1222. Here, too, the horizontal support 31 has two support rails 31a and 31b arranged at a distance from one another. Two spacers 34 arranged one above the other which connect the two support rails 31a and 31b to one another and adjust their distance from one another can be seen in FIG. 6. In the state shown, the two second abutment surfaces 1222a and 1222b rest against the inside of the walls of the two support rails 31a and 31b. In addition, the first bearing surface 121a of the abutment 121 rests on top of the horizontal support 31.
[0073] FIG. 7 shows a perspective view of the scaffolding section 100 from FIG. 6. In this perspective view, it can be seen that the two spacers 34 are offset in the longitudinal direction relative to the connecting component 1. In the perspective view, a plurality of receiving recesses 32 can be seen which are spaced apart from one another in the longitudinal direction of the horizontal support 31. The connecting component 1 and the horizontal support 31 can be connected by staking to a staking element 33 at any of the positions at which a receiving recess 32 is provided.
[0074] FIG. 8 shows a side view of a fourth embodiment of a scaffolding section 100 according to the invention. Unless otherwise described, FIG. 8 corresponds to the embodiment in FIG. 6. In contrast to the embodiment in FIG. 6, the horizontal support 31 in FIG. 8 has smaller dimensions and the distance between the two support rails 31a and 31b is smaller than in FIG. 6. Therefore, the connecting component 1 in FIG. 8 is connected to the horizontal support 31 via the first insertion interface 1221. For this purpose, the two first abutment surfaces 1221a and 1221b rest against the inside of the opposing walls of the support rails 31a and 31b. The first bearing surface 121a of the abutment 121 rests on top of the two support rails 31a and 31b.
[0075] FIG. 9 shows a perspective view of the scaffolding section 100 from FIG. 9. In a direct comparison to FIG. 7, it can be seen here that the connecting component 1 was simply rotated 90° about its longitudinal axis LA in order to adapt to the different distance between the support rails 31a and 31b. Also in the case of the scaffolding sections 100 in which a connecting component 1 according to the second embodiment is used, no part of the attachment region 12 projects in the transverse direction over the horizontal support 31. In the embodiment shown in FIGS. 8 and 9, the connecting component 1 and the horizontal support 31 can also be connected to one another in an additional positive-locking manner with the aid of a staking element 33, in which the staking element 33 is pushed into the securing recess 12211 and a receiving recess 32 aligned therewith.
