On the support surface 20 is according to a first embodiment, as in FIG. 3 shown, the fastening belt 3 positively placed or placed, whereby the load capacity of the Podestlagersystems 1 is increased. Alternatively, it is provided as in the embodiment of FIGS. 4A and 4B shown that between the bracket 11 and the shaft wall 12, a mounting template 21 is arranged or is that allows a simple fitting of the console 11 in the recess 13. For this purpose, the installation template 21 has an outer contour corresponding to the depression 13, so that it can be inserted into the depression 13 with a precise fit. In this case, the installation template 21 openings, which are arranged according to the threaded bushes to each other. On its side facing the bracket 11, the installation template 21 has a recess 22, which is designed to receive the console 11, in particular the fastening belt 3, in regions. In particular, the installation template 21 is designed such that it receives the console 11 at least substantially free of play and can be pre-assembled at this. The console 11 is then preferably used together with the installation template 21 in the recess 13, wherein the insertion bevel 19 ensures easy insertion and at the same time accomplishes an alignment of the bracket 11 with respect to the internal thread 16, so that in the connection the screw openings 5 are aligned with the internal threads 16 , By forming the screw openings 5 as slot openings, manufacturing and assembly tolerances can be compensated in a simple manner. The installation template 21 is preferably conical, so that it can be easily turned off and reused. At the in FIG. 3 1, the installation template 21 is preferably used in the production of the shaft wall 12 initially for aligning the sleeve rods 14 and removed before inserting the console 11 again. For this purpose, the above-mentioned openings in the installation template 21 are preferably designed to receive the threaded bushings in regions, in particular radially backlash-free or almost free of play, in order to align them in the manufacture of the shaft wall according to the arrangement of the screw openings 5.

FIG. 4B shows, as already mentioned, the mounted podium storage system 1 with a console 11 and previously removed installation template 21, wherein the console 11 is inserted into the recess 13 of the shaft wall 12. Through each screw hole 5, a fastening screw 23 is guided for fastening the bracket 11 to the shaft wall 12 so that its screw head rests against the fastening belt 3 and its threaded shaft is screwed into the internal thread 16 or is screwed. Once all the screws 23 are tightened, the recesses 10 are preferably subsequently filled with a filling compound 24, wherein preferably the same concrete mixture is used as the filling material, which was also used to produce the concrete casting 9. By the subsequent casting of the Recesses 10 is achieved that the screws 23 held securely and subsequent loosening of the screws 23 is prevented. In addition, by the filling of the recesses 10, the support surface 13 for a finished precast platform to be supported 25, in particular main or intermediate platform of the precast stairs, increased. The pedestal 25 can now finally be placed on the console 11 directly or with the interposition of a damping element 26, as indicated by arrows in FIG. 4B indicated. The Podestlagersystem 1 forms together with the precast platform 25 a pedestal system, especially for precast stairs. Conveniently, the pedestal system on more of the consoles and several of the precast podiums.

As in FIG. 4B can be seen, showing the precast platform 25, this preferably has a receiving recess 27 for receiving the console 11, in particular the concrete casting 9. In this case, the exceptional recess 27 is formed complementary to the concrete casting 9, so that the receiving recess 27 has a rectangular cross-section. The console 11 is then in the receiving recess 27 preferably at least substantially free of play. In the case in which the fastening screws 23 should be damaged in such a way that the screw connections are loosened, the console 11 in the recess 13 can only be pivoted so far by the weight force of the pedestal 25 until the concrete casting 9 canted in the receiving recess 27. Falling through the precast platform 25 is thus not possible because the weight is still transmitted through the console 11 on the support surface 20 in the shaft wall 12.

Preferably, it is also provided that above and below the console 11 in the region of the recess 13 in each case a mortar composition 28 is used, which closes the gap between the bracket 11 and the side edges of the recess 13.

By provided on the underside of the console 11 mortar mass 28, the support surface 20 is formed to support the console 11 in this case.

Alternatively, or in addition to providing the recess 13 is provided, shown here only by dashed lines, that the fastening belt 3 on its side facing away from the carrier belt 4 side has a retaining projection 29 which is formed substantially complementary with a receptacle 30 in the shaft wall 12 so that the Befestigungsgurt 3 with the retaining projection 29 in the receptacle 30 is inserted or inserted, as in FIG. 4B shown.

Preferably, at least the receptacle 30 is wedge-shaped, so that the holding projection 29 is easy to insert and centered by the receptacle 30 and fixed in a form-fitting manner. This can be dispensed with the support surface 20, which is then ultimately formed by the retaining projection 29. In any case, can be dispensed with the recess 13 and the console 11 are also arranged on a flat side wall of the shaft wall 12. In the case, the concrete casting 9 also preferably encloses the upper and lower edges and side edges of the fastening belt 3, so that only the side of the shaft wall 12 facing the retaining projection 29 is concrete-cast-free.

FIGS. 5A and 5B show a further embodiment of the bracket 11, without the concrete casting 9. According to the further embodiment, it is provided that the steel beam 2 is L-shaped, and that in addition to the stiffening ribs 6 a plurality of stiffening brackets 31 are arranged on the steel beam 2.

FIG. 5A shows a side view of the console 11, in which the course of the stiffening bracket 31 is clearly visible. The respective stiffening bracket 31 almost completely surrounds the carrier belt 4 and is arranged substantially at a distance therefrom. The stiffening bracket 31 is almost annular. In the present case, one end of the stiffening strap 31 is assigned to the fastening strap 3, so that a first section 32 of the stiffening strap 31 extends parallel to the carrier strap 4 and at a distance from it. An adjoining second section 33 of the stiffening bracket 31 runs perpendicular to the section 32 and parallel to the fastening belt 3, so that the section 33 extends beyond the carrier belt 4 also. The section 33 is adjoined by a further section 34, which in turn runs parallel to the carrier section 4 in the direction of the fastening belt 3. The section 34, however, ends before the fastening belt 3 and merges into a section 35 which extends perpendicular to the support section 4 parallel to the fastening belt 3 and ends at the underside of the carrier belt 4. Thus, the carrier belt 4 is almost completely in the present rectangular loop of the respective stiffening bracket 31. As an alternative to the right-angled embodiment of the loop, the stiffening bracket 31 may also have, for example, a circular, triangular or oval course.

FIG. 5B shows a perspective view of the console 11 with the plurality of stiffening ribs arranged thereon 6 and stiffening brackets 31. By the additional stiffening bracket 31, the connection between the steel beam 2 and the concrete casting 9, the in FIGS. 5A and 5B not shown, improved. In the stiffening bracket 31, the horizontal reinforcement is expediently inserted. Of course, according to a further embodiment, the stiffening brackets 31 may also be present on a T-shaped steel beam 2, as shown in the preceding embodiments.

Due to the Podestlagersystem 1 presented here, the installation of prefabricated stairs is significantly simplified. The pedestal storage system 1 expediently has a multiplicity of consoles 11 which can be attached to at least two opposite or angular shaft walls 12 in the manner described above. This makes it possible to mount a precast staircase in a short time in a staircase by first attaching the consoles 11 for an intermediate or main platform of the stairs to the shaft walls 12, as described above, and then the intermediate or main platform on the consoles 11th is hung up. Subsequently, one or more additional consoles 11 are arranged and fixed to the shaft wall 12 for the intermediate intermediate or main platform, and then placed the intermediate or main platform on the attached brackets 11.

Due to the prefabricated consoles 11, these can be mounted in a short time on the shaft wall 12, whereby a quick installation of the stairs is possible. The respective shaft wall 12 can be created in one go, there is no floor-wise structure of the shaft wall necessary. Instead, the respective consoles 11 are mounted in tiers. To speed up the construction process, for example by means of a Hubsteigers after completion of a stairwell core assembly of the consoles 11 and the pedestals done. The displacement of the precast platforms can take place in parallel to the displacement of the precast staircases. The use of a crane to move the elements is reduced to less than a day per staircase in a standard multi-storey apartment building. In addition, building construction cranes no longer have to be designed for the heaviest component, namely the staircases. Instead, the provision of larger and thus costly tower cranes can be reduced to lighter and thus cheaper tower cranes by short car crane inserts. Overall, therefore, the prefabrication and pre-assembly of the brackets 11 of the pedestal storage system 1 speeds up the construction process.
