DETAILED DESCRIPTION

[0101] FIG. 1 shows a first embodiment of a concrete shaping insert 1 according to the invention, which is formed to be arranged in a formwork before a concreting process. The concrete shaping insert 1 has a first fixing element 2, which is formed as a first reinforcing bar 3.

[0102] The concrete shaping insert 1 also has a second fixing element 4, which is formed as a second reinforcing bar 5. The first reinforcing bar 3 and the second reinforcing bar 5 are arranged parallel to one another and lying vertically one above the other.

[0103] In addition, the concrete shaping insert 1 has a plurality of displacement bodies 6, which are arranged between the first fixing element 2 and the second fixing element 4.

[0104] The first fixing element 2 and the second fixing element 5 are connected to one another by means of a plurality of connecting components 7 that can be attached without tools. Each of the displacement bodies 6 has an interstitial tube 8 which one of the connecting components 7 passes through it.

[0105] FIG. 2 shows the concrete shaping insert in a perspective view from a different angle.

[0106] FIG. 4 shows an arrangement of several of the concrete shaping inserts 1 in a formwork (not shown). The concrete shaping inserts 1 are arranged on a first reinforcement arrangement 9, which is formed as a first reinforcement grid. In FIG. 4, the first reinforcement arrangement 9 is only partially shown for clarity. There is a second strengthening arrangement 10 through the concrete shaping inserts 1, formed as a second strengthening grid. The second reinforcement arrangement 10 is also only partially shown for clarity.

[0107] After the reinforcement arrangements 9, 10 and the concrete shaping inserts 1 have been arranged within the formwork (not shown), concrete can be poured into the formwork. In particular, it is also possible to carry out the concreting process in several time-spaced steps.

[0108] FIG. 5 shows, in a cross-sectional view, a detail from a concrete ceiling which contains a concrete shaping insert 1 according to the invention. The concrete shaping insert 1 is arranged between the first reinforcement arrangement 9 and the second reinforcement arrangement 10.

[0109] Each of the displacement bodies has four pin-shaped spacers 11, which are evenly distributed along its equatorial circumference, which ensure that the desired distance between the displacement bodies 6 of the concrete shaping inserts 1 and the displacement bodies 6 of the adjacent concrete shaping inserts 1 (not shown) is maintained.

[0110] Each of the displacement bodies 6 is composed of a first displacement body part 13 and a second displacement body part 14, which is explained in detail below.

[0111] Each of the displacement bodies 6 has on its outside protruding members 12 arranged in a cross-like manner in pairs, which, starting from the outside of the respective displacement body 6, have a height preferably in the range of 10 mm to 25 mm, in particular 15 mm. The members 12 ensure in particular that the reinforcement arrangements 9, 10 are kept at a distance from the outside of the displacement bodies 6, so that it is ensured that the reinforcing bars of the reinforcement arrangement 9, 10 are surrounded by concrete 35 in the required manner. The lower members 12 also function as feet, which ensure that the displacement body 6 does not fall over.

[0112] The spaces between the displacement bodies 6 and the spaces above and below the concrete shaping insert 1 are completely filled with concrete 35, so that the reinforcement arrangements 9, 10 are also completely enclosed in concrete 35.

[0113] FIG. 6 shows an example of a first displacement body part 13, which can be assembled with the second displacement body part 14 shown in FIG. 7 without tools, namely by a latching process, to form a displacement body 6.

[0114] The first displacement body part 13 shown in FIG. 6 is key-shaped and has a first connecting device on the circumferential edge of the opening, which alternately includes latching tabs 15 and latching projections 16 on the circumferential edge.

[0115] The first displacement body part 13 has a first interstitial tube part 17 which, together with a second interstitial tube part 18 of a second displacement body part 14, as shown for example in FIG. 7, forms the interstitial tube 8 of the displacement body 6, which is shown in detail in FIGS. 11 and 12 is shown.

[0116] The first interstitial tube part 17 has a first contact surface 19 at the end. The contact surface 19 has two pins 20 and also has two through holes 21. The pins 20 and the through holes 21 serve to produce a form-fit connection with the complementary second interstitial tube part 18 of a second displacement body part 14.

[0117] The first displacement body part 13 has four protruding spacers 11 distributed uniformly on the outer circumferential edge, which, in the assembled state, come into contact with corresponding spacers 11 of the second displacement body part 14. The spacers 11 ensure that the desired distance between the displacement bodies 6 of the concrete shaping inserts 1 and the displacement bodies 6 of adjacent concrete shaping inserts 1 is maintained. For this purpose, provision is made for the displacement bodies 6 to be arranged such that the free ends of the spacers 11 of adjacent displacement bodies 6 adjacent to each other.

[0118] The first displacement body part 13 has on its outside (not shown in FIG. 6) protruding members 12 which, as already explained, ensure the necessary spacing from adjacent reinforcements. In addition, the members 12 act as feet and ensure that the displacement body 6 can safely stand.

[0119] The second displacement body part 14 has a plurality of bearing elements 22 (not shown in FIG. 6) on its outside, which are formed to interact with the first fixing element 2. The bearing elements are formed exactly as in the case of the second displacement body part 14 shown in FIG. 7.

[0120] FIG. 7 shows a second displacement body part 14 which, in this exemplary embodiment, has the same design as the first displacement body part shown in FIG. 6. This is advantageous with regard to the use of identical parts. However, this is not absolutely necessary. On the contrary, it can also be advantageous if the first displacement body part 13 and the second displacement body part 14 are not formed to be completely identical, but at least differ in height, which is explained in detail below.

[0121] The second displacement body part 14 has on its outside protruding members 12 which, as already explained, ensure the necessary spacing from adjacent reinforcements. The second displacement body part 14 has latching tabs 15 and latching projections 16 that alternate around the circumference of the opening. The locking tabs 15 of the second displacement body part 14 are formed to interact with the locking projections 16 of the first displacement body part 13, while the locking projections 16 of the second displacement body part 14 are formed to interact with the locking tabs 15 of the first displacement body part 13.

[0122] The first displacement body part 13 and the second displacement body part 14 can be connected to one another in a latching manner by executing a connecting movement perpendicular to the plane of their cover openings by means of the latching tabs 15 and the latching projections 16 of the connecting devices.

[0123] The second displacement body part 14 has a plurality of bearing elements 22 on its outer side which are formed to interact with the second fixing element 4. The bearing elements 22 each consist of crossed members, one of the crossed members each having a depression 23 for the second fixing element 4, which is formed as a reinforcing bar 5. The bearing elements 22 are each arranged between two mutually parallel members 12 and are dimensioned such that the inserted second fixing element 4 does not protrude upward beyond the members 12.

[0124] There is a total of four pairs of bearing elements 22, only four of the bearing elements 22 being required when using a second fixing element formed as a reinforcing bar, which are arranged in two pairs and in a straight line on both sides of the opening of the tube 8. The four other bearing elements 22, which are arranged along a straight line, which are arranged perpendicular to the straight line along which the bearing elements 22 used are arranged, are not required when using a second fixing element which is formed as a reinforcing bar.

[0125] However, the special arrangement of the bearing elements makes it possible to use a first displacement body part 13 as a second displacement body part 14 and vice versa. In this respect, a rotationally symmetrical design of the displacement body parts 13, 14 with respect to the central axis running through the interstitial tube 8 is particularly advantageous. In the present case, the displacement body parts 13, 14 have fourfold rotational symmetry. This principle can also be implemented advantageously when the displacement body parts have different heights.

[0126] FIG. 8 shows the second displacement body part 14 in a plan view from above.

[0127] The second displacement body part 14 has, as already mentioned, a second interstitial tube part 18 which, together with the first interstitial tube part 17 of the first displacement body part 13, forms the interstitial tube 8. The second interstitial tube part 18 has a circumferential collar 25 at the end, which has two second passage openings 24. The first pins 20 of the first displacement body part 13 can engage positively in the through openings 24. The collar 25 for its part carries pins (not shown in this figure) which engage in the through openings 21 of the first displacement body part 13. On the side not shown in FIG. 8, the circumferential collar 25 provides a second contact surface which is in contact with the first contact surface 19 of the first displacement body part 13.

[0128] FIG. 9 illustrates a potential procedure for producing a concrete shaping insert 1 according to the invention. For this purpose, a first displacement body part 13 is connected in a latching manner to a second displacement body part 14, a connecting movement being carried out perpendicular to the plane of the cover openings.

[0129] During the locking process, the locking tabs 15 and the locking projections 16 lock into one another. At the same time, the first contact surfaces of the first interstitial tube part 17 and the second interstitial tube part 18 come into contact with one another, with a form-fit connection, namely a tongue joint, being established between the first interstitial tube part 17 and the second interstitial tube part 18.

[0130] The displacement body 6 is then disposed between a first fixing element 2 and a second fixing element 2 by connecting the fixing elements 2, 4 without tools by means of a connecting component 7 that proceed through the interstitial tube 8.

[0131] FIG. 10 shows the displacement body 6 disposed between the first fixing element 2 and the second fixing element 4 in a plan view from below, only a portion of the reinforcing bar 3, which forms the first fixing element 2, being shown so as not to close the spacers 11 in the form cover up.

[0132] FIG. 11 shows the displacement body 6 disposed between the first fixing element 2 and the second fixing element 4 in a representation that allows a view into the interior. It can be seen in particular that the first interstitial tube part 17 and the second interstitial tube part 18 bear against one another and together form the interstitial tube 8. The interstitial tube 8 has, in a cross-sectional plane perpendicular to its direction of longitudinal extension, a shape that deviates from the circular shape, namely a square shape.

[0133] FIG. 12 shows a further detailed view which allows a view into the interior of the interstitial tube 8 through which the connecting component 7 proceeds.

[0134] FIGS. 13 and 14 show details of a second embodiment of a concrete shaping insert 1 according to the invention. In contrast to the embodiment shown in FIGS. 1 to 12, the first displacement body part 13 and the second displacement body part 14 are not formed the same in this embodiment, but differ in terms of their height in the direction of the longitudinal extent of the interstitial tube. In this embodiment, the first displacement body part 13 can for example have a height of 110 mm, while the second displacement body part 14 has a height of for example 50 mm.

[0135] However, the first connecting device of the first displacement body part 13, the second connecting device of the second displacement body part 14 are the same and are formed in a manner, in particular rotationally symmetrical, that it is possible to selectively connect only lower displacement body parts 13, 14, for example 50 mm in height, in order to achieve a result To achieve displacement body 6 with a total height of 100 mm, or exclusively to connect higher displacement body parts 13, 14 of for example 110 mm height with each other in order to achieve a displacement body 6 with a total height of 220 mm, or (as in the present example) lower and to connect higher displacement body parts 13, 14 to one another in order to achieve a displacement body 6 with a total height of 160 mm as a result.

[0136] In this way, a total of three different heights can be achieved through the different possible combinations of only two types of displacement body parts 13, 14. With a number of three different displacement body parts 13, 14 of different heights, a total of six different heights can be achieved through the different possible combinations. This procedure represents an independent inventive concept, which can also be advantageously implemented detached from the presence of a connection component that can be attached without tools and in particular also detached from the implementation of an interstitial tube 8 and/or a connection component 7 proceed through the interstitial tube.

[0137] FIG. 15 shows a detailed view of the assembled displacement body 6 with a total height of 160 mm.

[0138] FIG. 16 shows an exemplary embodiment of a connecting component 7 that can be attached without tools from which, the first fixing element 2 and the second fixing element 4 can be connected to one another. The connecting component 7 has a first connecting element 26 which is formed for mechanical coupling to the first fixing element 2. In addition, the connecting component 7 has a second connecting element 27, which is formed in particular for mechanical coupling to the second fixing element 4. The first connecting element 26 is formed as a latching device and has an elastic locking hook 28. The locking hook 28 is formed to grip around a rod-shaped section of the first fixing element 2, in particular in a form-fitting manner. For this purpose, the elastic locking hook 28 has a receptacle 29 for the rod-shaped section of a first fixing element 2 and an insertion gap 30 through which the rod-shaped section of the first fixing element 2 can be inserted into the receptacle 29. The passage width of the insertion gap 30 is smaller than the inner diameter of the receptacle 29. In this way it is ensured that the connecting component 7 cannot automatically detach itself from the first fixing element 2 after it has snapped into place. This is especially not the case if the second connecting element 27 has not yet been connected to the second fixing element 4. Rather, the first connecting element 26 is advantageously formed in a manner that the connecting component 7, after it has been connected to a rod-shaped section of the first fixing component 2, can be pivoted about the rod-shaped section without inadvertently detaching from the rod-shaped section.

[0139] The second connecting element 27 is also formed as a latching device and has an elastic locking hook with an indentation 31 for a rod-shaped section of the second fixing element 4. A guide element 32 with a guide surface 33 adjoins the indentation 31.

[0140] The connecting component 7 has an elongate web 34. The first connecting element 26 is arranged at one end of the web. The second connecting element 27 is arranged at the other end of the web 34.

[0141] FIGS. 17 to 19 illustrate schematically how the connecting component is used.

[0142] for clarity, the first connecting element 26 is latched to a rod-shaped section of the first fixing element 2, which is shown in FIG. 17. In particular, the connecting component 7 can now be guided through the interstitial tube 8, but this is not shown in the drawings for the clarity.

[0143] The connecting component 7 is then pivoted about the rod-shaped section of the first fixing element 2 until it reaches a rod-shaped section of the second fixing element 4, which is shown in FIG. 18. When the pivoting movement continues, the rod-shaped section of the second fixing element 4 slides along the guide surface 33, as a result of which the elastic locking hook of the second connecting element 27 is temporarily bent until the rod-shaped section reaches the indentation 31 and engages, which is shown in FIG. 19.

[0144] FIG. 20 shows an assortment of connecting components 7 which can be attached without tools and which have different lengths. This range can be used in particular in connection with the use of displacement bodies 6 of different total heights, for example for concrete ceilings of different heights. The assortment is preferably tailored to the fact that many different overall heights are realized by combining first displacement body parts 13 and second displacement body parts 14 which have different heights.

[0145] FIG. 21 shows a detailed illustration of a third exemplary embodiment of a concrete shaping insert 1 according to the invention, in which a connecting component 7 was used, which is shown in FIG. 16. The detailed representation allows a view through the interstitial tube 8. It can be seen in particular that the first fixing element 2 is latched to the first connecting element 26, while the second fixing element 47 is latched to the second connecting element 27 of the connecting component 7.

[0146] FIG. 22 shows a detailed view of the third embodiment of a concrete shaping insert 1 according to the invention from above, while FIG. 23 shows a detailed view of the third embodiment of a concrete shaping insert 1 according to the invention from below.

[0147] FIG. 24 shows a detailed view of a fourth exemplary embodiment of a concrete shaping insert 1 according to the invention, the first fixing element 2 and the second fixing element 4 and the connecting element 7 not being shown for clarity. In this exemplary embodiment, the displacement bodies 6 are connected to one another with a displacement body connector 35 at the equatorial height of the displacement bodies 6. The additional connecting component 35 also ensures in particular that the desired spacings between the displacement bodies 6 are maintained. A detailed view of a possible embodiment of the displacement body connector 35 is shown in FIG. 28.

[0148] FIG. 25 shows a detailed view of a fifth exemplary embodiment of a concrete shaping insert 1 according to the invention, the first fixing element 2 and the second fixing element 4 and the connecting element 7 not being shown for clarity. In this exemplary embodiment, the displacement bodies 6 are connected to one another at the top with a displacement body connector 36. The displacement body connector 36 is hooked into a bearing element 22. The displacement body connector 36 in particular also ensures that the desired distances between the displacement bodies 6 are maintained. A detailed view of a possible embodiment of the displacement body connector 36 is shown in FIG. 29.

[0149] FIG. 26 shows a detailed view of a sixth embodiment of a concrete shaping insert 1 according to the invention, the first fixing element 2 and the second fixing element 4 and the connecting element 7 not being shown for clarity.

[0150] In this exemplary embodiment, the displacement bodies 6 are connected to a displacement body connector 35 at the equatorial height of the displacement body 6 and are also connected to one another at the top with a displacement body connector 36.

[0151] FIGS. 29 and 30 show a first displacement body part 13 and a second displacement body part 14 in an alternative design for a concrete shaping insert 1 according to the invention, in particular for a concrete shaping insert 1 as shown in FIGS. 24, 25 and 26. The displacement body parts 13, 14 are formed identically and have a plurality of channels 37 into which lines (not shown), in particular electrical lines, can be placed. In particular, it may be advantageous to install the second fixing element 4 after the lines have been laid, so that the lines are additionally secured in their position by the second fixing element 4. Alternatively, it is also possible, for example, to pull the lines through under the second fixing element 4 or to lay them above the second fixing element 4.

[0152] The displacement body 6 produced from the first displacement body part 13 and the second displacement body part 14 has flattened side surfaces and is particularly high in relation to its diameter. The flattened side surfaces make it possible to fill the space between adjacent displacement bodies 6 with a largely uniformly thick layer of concrete.

[0153] These displacement bodies 6 are particularly intended to be used with particularly thick concrete ceilings. In this embodiment, too, it is possible (according to an independent inventive concept) to combine first displacement body parts 13 and second displacement body parts 14 of different heights with one another or, alternatively, to use the same displacement body parts 13, 14.

[0154] FIG. 31 shows an embodiment of a positioning aid 38 which is plate-shaped. The positioning aid 38 can be used when assembling a concrete shaping insert according to the invention.

[0155] The positioning aid 38 is formed to hold exactly one displacement body 6 upright for an assembly process. The positioning aid 38 has first recesses 39 which are specially formed and arranged to receive the protruding members 12 of a displacement body 6. The positioning aid 38 has second recesses 40 which are specially formed and arranged to receive the bearing elements 22 of a displacement body 6. The positioning aid 38 has a third recess 41 which is specially formed and arranged to receive the first connecting element 26 of the connecting component 7. The positioning aid 38 has a fourth recess 42 which is specially formed to receive the web 34 of the connecting component 7. The positioning aid 38 has a fifth recess 43 which is specially formed and arranged to receive the first fixing element 2.

[0156] The positioning aid 38 has form-fit sections 44 which make it possible to connect several similar positioning aids 38 to one another to form a positioning aid system 45, which is shown in FIG. 32. The form-fit connections are formed in a similar way to puzzle pieces.

[0157] The assembly process of the concrete shaping insert 1 proceeds in a manner that several of the positioning aids 38 are first connected to one another in the required number and laid out on the floor. Then the first fixing element 2 and the required connecting components 7 are inserted into the recesses 421, 42, 43 of the positioning aids 38 provided for this purpose. In a next step, the displacement bodies 6 are positioned, the connecting component 7 being guided through the tube 8 and the members 12 and the bearing elements 22 of the respective displacement body 6 being inserted (preferably in a clamping manner) into the corresponding recesses 39, 40 of the respective positioning aid 38 so that the displacement body 6 is held upright by the positioning aid 38 as a result. The connecting components 7 are then coupled to the second fixing element 4.

[0158] The finished concrete shaping insert 1 is then released from the positioning aids 3 and brought to the place provided for a concreting process. The positioning aids 38 can then be used again for the assembly of the next concrete shaping insert 1. Finally, the positioning aids 38 can be released from one another again. The positioning aids 38 can advantageously be stacked on top of one another for transport.

[0159] FIG. 33 shows a seventh exemplary embodiment of a concrete shaping insert 1 according to the invention, which is formed to be arranged in a formwork before a concreting process. The concrete shaping insert 1 has a first fixing element 2, which is formed as a first reinforcing bar 3. The concrete shaping insert 1 also has a second fixing element 4, which is formed as a second reinforcing bar 5. The first reinforcing bar 3 and the second reinforcing bar 5 are arranged parallel to one another and lying vertically one above the other.

[0160] In addition, the concrete shaping system 1 has several identical displacement bodies 6, which are arranged in a row in pairs one above the other between the first fixing element 2 and the second fixing element 4. It would also be possible to arrange different displacement bodies 6, in particular different heights, one above the other.

[0161] The first fixing element 2 and the second fixing element 5 are connected to one another by means of a plurality of connecting components 7 that can be attached without tools. Each of the displacement bodies 6 has an interstitial tube 8. The interstitial tubes 8 of the displacement bodies 6 arranged one above the other are aligned with one another. A connecting component 7, which connects the first fixing element and the second fixing element to one another, through the aligned interstitial tubes 8 of the displacement bodies arranged one above the other.

[0162] The downwardly directed members 12 of the upper displacement body 6 and the upwardly directed members 12 of the lower displacement body 6 function in this embodiment as coupling means which interlock. The coupling means advantageously prevent the displacement bodies 6 from moving relative to one another, in particular during a concreting process.
