[0002] Due to site limitations, there is no assembly construction space at the proposed building location. Steel components must be assembled near the proposed building and then moved as a whole to the designed positioning point. Traditional construction technology cannot meet the installation requirements.

[0003] Existing prefabricated composite floor slabs require extensive on-site scaffolding support during installation. This labor-intensive process, along with the time-consuming removal of the scaffolding after the upper reinforcement bars are tied and the concrete is poured, results in a lengthy construction cycle and high transportation costs. Summary of the Invention

[0004] The purpose of the utility model is to provide a detachable mounting support steel corbel for prefabricated floor slabs, so as to solve the problem of being unable to install due to insufficient construction space at the proposed building site.

[0005] To this end, the utility model proposes a detachable mounting support steel corbel for prefabricated floor slabs, which is used to support the installation of prefabricated PKⅢ panels on prefabricated composite beams. The support steel corbel includes: a top plate, side plates and a pair of reinforcing plates; the top plate is arranged perpendicular to the side plates and is supported and fixed by the reinforcing plates.

[0006] The side panels are provided with mounting through holes, which are fixedly connected to the prefabricated composite beams by bolts passing through the mounting through holes, so that multiple supporting steel corbels are installed on the inner side walls of the prefabricated composite beams; a horizontally arranged square steel tube is provided above the top plate, and the square steel tube is used to support the outer end of the prefabricated PKⅢ plate; thereby, the prefabricated PKⅢ plate is supported on the prefabricated composite beams.

[0007] As a preferred technical solution of the present application, a distance is maintained between the top plate and the square steel tube to form a leveling space; a plurality of leveling gaskets are arranged in the leveling space.

[0008] As a preferred technical solution of the present application, a plurality of supporting steel corbels are provided under each of the square steel tubes, and the supporting steel corbels are arranged at intervals.

[0009] As a preferred technical solution of the present application, the supporting steel corbels are arranged equidistantly along the length direction of the supporting steel corbels.

[0010] As a preferred technical solution of the present application, a plurality of bolt sleeves are reserved on the side walls of the prefabricated composite beam.

[0011] As a preferred technical solution of the present application, the reinforcing plate is a right-angled triangle plate.

[0012] As a preferred technical solution of the present application, each of the side panels is provided with two mounting through holes, and the two mounting through holes are spaced apart in the vertical direction.

[0013] As a preferred technical solution of the present application, the prefabricated composite beams are replaced with double-sided composite walls.

[0014] This utility model provides a detachable support steel bracket for prefabricated floor slabs. Using surrounding concrete beams, walls, columns, and other components as the main support structure, it can reduce the need for extensive on-site scaffolding, facilitating the fixing of prefabricated floor slabs and subsequent reinforcement work. Without the obstruction of scaffolding, it also allows for extensive inspection work at the bottom of the floor slab, resolving the issue of installation difficulties caused by insufficient construction space on site. Furthermore, it reduces on-site workload and accelerates the construction cycle.

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] like Figures 1 to 3 As shown, the detachable support steel corbel for prefabricated floor slabs of the present invention comprises: a top plate 61, side plates 62 and a pair of reinforcing plates 63; the top plate 61 and the side plates 62 are arranged perpendicularly and supported and fixed by a pair of reinforcing plates 63, wherein the reinforcing plates 63 are right-angled triangular plates, and the two end faces of the reinforcing plates 63 are opposite to the top plate 61 and the side plates 62 respectively, thereby increasing their structural strength.

[0026] Specifically, a mounting through hole is provided on the side panel 62, and bolts are passed through the mounting through hole to fix the supporting steel corbel to the inner wall of the prefabricated composite beam; a horizontally arranged square steel tube 4 is provided above the top panel 61, and the square steel tube 4 is used to support the outer end of the prefabricated PKⅢ panel 2; thereby supporting the prefabricated PKⅢ panel on the prefabricated composite beam 1.

[0027] like Figure 1 As shown, a distance is maintained between the top plate 61 and the square steel tube 4 to form a leveling space, and a number of leveling gaskets 5 are arranged in the leveling space. The number of leveling gaskets 5 is set according to actual needs to keep the upper surface of the square steel tube 4 level, and thus keep the prefabricated PKⅢ plate 2 above the square steel tube 4 level.

[0028] like Figure 2 As shown, each prefabricated composite beam 1 is provided with a plurality of supporting steel corbels 6, that is, a plurality of supporting steel corbels 6 are provided under each of the square steel tubes 4, and the supporting steel corbels 6 are arranged equidistantly along the length direction of the supporting steel corbels 6; the square steel tubes 4 are supported by a large number of supporting steel corbels 6 to keep them horizontal and avoid bending.

[0029] like Figure 2 、 Figure 3 As shown, during the fabrication of the prefabricated composite beam 1, several bolt sleeves 7 can be pre-set at fixed intervals on the beam 1. The removable supporting steel corbels 6 are secured with bolts and bolt sleeves 7. Compared to drilling holes and installing anchor bolts after the prefabricated composite beam 1 is formed, pre-setting the bolt sleeves 7 increases its structural strength, making the entire construction structure and process safer and more reliable.

[0030] In addition, each of the side plates 62 is provided with two mounting through holes, and the two mounting through holes are spaced apart in the vertical direction; thereby, the connection strength between the supporting steel corbel 6 and the prefabricated composite beam 1 can be improved.

[0031] In another embodiment, Figure 4 、 Figure 5 As shown, in the above-mentioned detachable support steel corbel applied to prefabricated floor slabs, the prefabricated composite beam 1 is replaced by a double-sided composite wall 3, that is, the above-mentioned support steel corbel 6 is detachably installed on the double-sided composite wall 3, so that the support steel corbel 6 of the present application can be used not only in bridges, but also in house construction, thereby increasing its scope of application.

[0032] The working principle and working process of the detachable support steel corbel applied to prefabricated floor slabs of the present invention are briefly described below.

[0033] First, M16 bolt sleeves are reserved at fixed intervals on concrete beams, walls, columns, and other components during fabrication. Before installing the floor slab, removable steel corbels are secured with bolts and bolt sleeves. A full-length square tube of the required specification is then placed on top to support the slab on both sides. After all the upper reinforcement bars are tied and the concrete is poured, the removable steel corbels can be removed and reused.

[0034] In order to reduce the workload on site and speed up the construction period, a detachable support steel bracket is used for prefabricated floor slabs. The surrounding concrete beams / walls / columns and other components are used as the main support body. This can reduce the large amount of manpower required to set up scaffolding on site, facilitate the fixation of prefabricated floor slabs and the subsequent reinforcement construction work; without the obstruction of scaffolding, inspection work can also be carried out on a large scale at the bottom of the floor slab.

[0035] In addition to the above-mentioned features, the detachable installation supporting steel corbel used for prefabricated floor slabs of the present invention also has the following features: 1) It can greatly reduce the workload on site and speed up the construction period; 2) The surrounding concrete beams / walls / columns and other components can be directly used as the supporting body without the need to add other large additional supporting bodies; 3) It can reduce a large amount of manpower on site to set up scaffolding, making it convenient for the fixing of prefabricated floor slabs and the subsequent reinforcement construction work; 4) The supporting corbel parts can be flexibly disassembled and the installation positioning can be flexibly adjusted.

[0036] The foregoing description is merely a preferred embodiment of the present application and is not intended to limit the present application. Persons skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
