DETAILED DESCRIPTION
(12) FIG. 1a shows a portion of the scaffold 10. The scaffold 10 has a plurality of vertical scaffolding poles 12a-12f in the mounted state. The scaffolding poles 12a-12f each have an essentially horizontal fastening plate 14a-14f The fastening plates 14a-14f are each in the form of a rosette. The fastening plates 14a-14f are used to arrange further in scaffolding elements that are not depicted in FIG. 1a.
(13) Two scaffolding posts 12a-12f are connected by a cross-bar 16a-16c. Linings can be hooked into the cross-bars 16a-16c, wherein in FIG. 1a, a first lining 18a and a second lining 18b are arranged between the cross-bars 16a and 16b.
(14) To prevent a worker from falling on the scaffold 10, railings 20a, 20b are provided. The railings 20a, 20b are pre-mountable, i.e. they are mountable before a worker steps onto the scaffolding level in which the railings 20a, 20b protect the worker from falling. The railing 20a is depicted in FIG. 1a in the fully assembled state in the lower scaffolding level, i.e. in the n-th scaffolding level, in which the worker is also located. By contrast, the railing 20b is already hooked on the scaffolding pole 12e that already belongs to the next higher, upper or (n+1)th scaffolding level from the lower scaffolding level out from one end.
(15) FIG. 1b shows the further assembly of the railing 20b. The railing 20b is arranged at the other end on a scaffolding pole 12g of the scaffold 10, which is connected to a scaffolding pole 12h via a cross-bar 16d.
(16) FIG. 1c shows the scaffold 10 in a further mounted state. Accordingly, the scaffolding pole 12g is inserted on the scaffolding pole 12a and the scaffolding pole 12h is inserted on the scaffolding pole 12b. The railing 20b was pivoted upward during assembly of the scaffolding poles 12g and 12h and is now already mounted on the scaffold 10, before further linings (not depicted) are mounted between the cross-bars 16c, 16d. The scaffold 10 according to the invention can thus be mounted particularly securely. It is also possible here to remove the railing 20b on both sides of the scaffolding poles 12e and 12g if, for example, something must be brought laterally onto the scaffold 10 with a crane. The disassembly of the railing 20b is done in the reverse order according to FIGS. 1c-1a. The railing 20b can thus be both mounted and dismantled in advance.
(17) The railings 20a shown in FIGS. 1a-1c are mounted at waist height of a worker; the railing 20b is mounted at knee height of a worker. Together with the railing 20a at waist height, another railing 20b (not shown) in the same scaffolding level at knee height can be both mounted and dismantled in advance. Furthermore, together with the railing 20b at knee height another railing (not shown) in the same scaffolding level at waist height can be both mounted and dismantled in advance.
(18) FIG. 2 shows a scaffolding element 22 with a scaffolding pole 12i without a fastening plate and without a cross-bar. The scaffolding pole 12i has a longitudinal axis 24. Fastening elements 26a, 26b are arranged parallel to the longitudinal axis 24 and spaced from each other on the scaffolding pole 12i, in particular welded.
(19) FIG. 3a shows the railing 20a (see FIG. 1a) for the arrangement on the fastening element 26a or 26b (see FIG. 2). The railing 20a has a longitudinal axis 28. The railing 20a is formed mirror-symmetrically with respect to a plane of symmetry extending perpendicular to the drawing plane and intersecting the longitudinal axis 28. The railing 20a is formed mirror-symmetrically with respect to a plane of symmetry extending perpendicular to the drawing plane and extending perpendicular to the longitudinal axis 28. In particular, the two ends 30a, 30b of the railing 20a are formed as mirror images of each other. A worker can therefore mount the railing 20a largely independent of its orientation. From FIG. 3a it can be seen that the railing 20a has first through-openings 32a, 32b and second through-openings 34a, 34b. A fastening element 26a, 26b (see FIG. 2) can be inserted into any one of the through-openings 32a, 32b, 34a, 34b.
(20) FIG. 3b shows an enlarged partial view of the railing 20a in the region of the end 30a. From FIG. 3b it can be seen that the through-openings 32a, 34a are each configured in the form of a slot. The distance A of the through-openings 32a, 34a to the respective outer edges 36a, 36b of the end 30a is equal. Preferably, the distance A is smaller than the width B of the through-openings 32a, 34a perpendicular to the longitudinal axis 28. By virtue of the relatively narrow webs 38a, 38b with the width A, the railing 20a can be mounted relatively closely to the scaffolding pole 12i (see FIG. 2). This will be apparent from FIG. 4b below.
(21) FIG. 4a and FIG. 4b show the scaffolding element 22 with the railing 20a. The railing is respectively shown in a state in which it was raised by mistake.
(22) It can be seen from FIG. 4a that the first end 30a—as well as the second end 30b (see FIG. 3a)—is done by flattening the railing tube.
(23) From FIG. 4b it can be seen that the clear width LW between the scaffolding pole 12i and a projection 54 (see FIG. 5b), in particular a bead 56 (see FIG. 5b), must only be slightly wider than the width A of the web 38a or 38b (see FIG. 3b). As a result, the clearance width available for a worker between the fastening element 26a and the opposite side, be it a building or another railing or another fastening element 26d, is hardly reduced. The clearance width is only reduced by the overhang V of the fastening element 26a. The overhang V is comprised of the clear width LW and the cross-sectional width Q. In addition, the shape of the fastening element 26a minimizes the danger of a worker located on the scaffold 10 (see FIGS. 1a-1c) getting caught or injured on the fastening element 26a-c.
(24) A dotted line 40 indicates the locking position of the railing 20a. As shown by an arrow 42, the railing 20a can be rotated by 90° and then be removed in the direction of an arrow 44 from the fastening element 26a. The removal direction according to the arrow 44 extends parallel to the longitudinal axis 58 of the free end 52 of the fastening element 26a.
(25) From an overview of FIGS. 3a, 3b and 4b, it can also be seen that the width B of the through-openings 32a, 32b, 34a, 34b corresponds to the maximum cross-sectional width Q of the fastening element 26a with a clearance fit.
(26) FIG. 5a shows the fastening element 26a and a fastening element plate 46. The fastening element plate 46 serves for the easy welding of the fastening element 26a to the scaffolding pole 12i (see FIG. 4a) or to a scaffolding pole 12a-12h according to FIGS. 1a-1c. The fastening element plate 46 is thus integrally formed or welded to a side 48a or first main side of the fastening element plate 46 on the fastening element 26a. On the opposite side 48b or second main side of the fastening element plate 46, the fastening element plate 46 is joined to the scaffolding pole 12i, in particular welded to it.
(27) FIG. 5b shows a side view of the fastening element 26a with the fastening element plate 46. From FIG. 5b it can be seen that the fastening element 26a has a fastening element body 50. The fastening element body 50 is L-shaped. The fastening element body 50 has the shape of a pin or bolt with constant cross-section. A free end 52 of the fastening element body 50 serves for receiving a through-opening 32a, 32b, 34a, 34b (see FIG. 3a).
(28) A projection 54 on the fastening element body 50 points toward the scaffolding pole 12i (see FIG. 4a) to prevent an unintentional detachment of the railing 20a (see FIG. 4a). The projection 54 is configured in the form of a part of a bead 56. As can be seen from an overview of FIGS. 5a and 5b, the bead 56 extends radially around the fastening element body 50, wherein the bead 56 does not protrude beyond the fastening element body 50 on the side pointing away from the scaffolding 12i (see FIG. 4a).
(29) The free end 52 of the fastening element body 20 has a longitudinal axis 58 which runs essentially parallel to the longitudinal axis 24 (see FIG. 4b) of the scaffolding pole 12i (see FIG. 4a).
(30) An overview of FIGS. 4a, 4b, 5a, 5b shows that the railing 20a may indeed rotate about its longitudinal axis 28 and move along the fastening element body 50 when inadvertently lifted, but on contact with the bead 56 rotates beyond 90° until the inner edge of the corresponding through-opening 32a, 32b, 34a, 34b abuts the free end of the fastening element 26a. In this position, an unintentional further lifting of the railing 20a and thus an inadvertent release is not possible. The railing 20a is thus securely fastened to the scaffolding pole 12i.
(31) FIG. 6 shows another exemplary embodiment of a fastening element 26c. The fastening element 26c corresponds to the fastening elements 26a, 26b (see FIG. 2), wherein no fastening element plate 46 (see FIGS. 5a and 5b) is provided for mounting the fastening element 26c. The fastening element 26c may be arranged by stud welding on a scaffolding pole 12a to 12i (see FIGS. 1a-1c and 2); the end pointing toward the scaffolding pole 12a to 12i has a suitable geometry (not depicted) for this depending on the selected method.
(32) In the context of viewing all the figures of the drawings together, the invention relates comprehensively to a scaffolding element 22 having a scaffolding pole 12a-12i, wherein at least one fastening element 26a-26c is arranged or formed on the scaffolding pole 12a-12i. The fastening element 26a-26c preferably has a fastening element body 50. The fastening element body 50 may have an L-shaped design. Preferably, the free end 52 of the fastening element body 50 in the mounted state of the scaffolding element 22 points straight up. On the fastening element body 50, a projection 54 is arranged or formed below the free end 52 in particular in a section parallel to the longitudinal axis 24 of the scaffolding pole 12a-12i. The projection 54 may be part of a U-shaped bead 56.
