[0002] A composite floor slab is an assembled monolithic floor slab formed by laminating a precast slab and a cast-in-place reinforced concrete layer. Currently, precast composite floor slabs widely used in the domestic construction engineering field require vertical support frames to be arranged below the precast composite floor slabs during the construction process and within a certain curing time after the concrete of the cast-in-place layer above is poured, so as to ensure that the precast part and the cast-in-place composite part form a reliable whole and meet the requirements of various loads during construction.

[0003] According to the authorized announcement number CN 216446275 U, a precast concrete composite slab without support and with built-in truss bars is disclosed, which includes a precast floor slab and a steel mesh embedded in the precast floor slab. Specifically, it further includes at least two steel truss beams parallel to the longitudinal direction of the precast floor slab. The lower part of the steel truss beam is embedded in the precast floor slab and fixedly connected to the steel mesh. The two ends of the steel truss beam extend out of the precast floor slab, and cushion blocks are arranged at the bottoms of both ends. The size of the cushion blocks meets the requirement that the precast floor slab can be lapped on the beam or wall. In the utility model, the two ends of the steel truss beam extend out of the precast floor slab, and cushion blocks are arranged at the bottoms of both ends, so that the precast floor slab can be lapped on the beam or wall, realizing the non-support of the precast floor slab, shortening the project construction period, improving the construction efficiency, and saving the construction cost.

[0004] During the welding process of the above device, it is necessary to continuously support the steel bars, so that a single worker cannot quickly and efficiently weld the steel bars inside the composite slab, greatly reducing the production efficiency. Therefore, a truss composite slab without protruding steel bars is needed now. Content of the Utility Model

[0005] The purpose of the utility model is to provide a truss composite slab without protruding steel bars, and by setting a detachable mating installation plate and mating steel bars, limit steel bars and bent connecting steel bars that can be conveniently installed, the convenience of welding and pouring of the composite slab is improved, so as to solve the technical problems mentioned in the background technique.

A number of arc-shaped covers are placed equidistantly on the upper part of the limiting steel bars. Two groups of bent connecting steel bars are symmetrically welded and installed on both sides of each group of arc-shaped covers.

[0008] Preferably, a number of connecting slots are equidistantly opened on the upper surface of the reinforcing plate. A positioning plug is fixedly installed at the center of the bottom of the cooperating mounting plate. The positioning plug is hermetically inserted into the connecting slot.

[0009] Preferably, the cooperating mounting plate is corrugated. The bottom of the cooperating mounting plate is attached to the upper surface of the reinforcing plate. A set of limiting sleeves are respectively installed at the top of each support frame.

[0010] Preferably, each group of positioning seats are correspondingly attached to the side wall of the cooperating mounting plate. Connecting slots are opened at the positions corresponding to the cooperating mounting plate for two symmetrically arranged positioning seats. A set of arc-shaped supporting plates are fixedly installed at the top of each group of positioning seats.

[0011] Preferably, each group of cooperating steel bars are placed inside the corresponding arc-shaped supporting plate and welded. The limiting steel bars are inserted into the limiting sleeves and welded.

[0012] Preferably, the arc-shaped covers are welded to fit the outer arc surface of the limiting steel bars. The ends of each group of bent connecting steel bars are welded to fit the outer arc surface of the corresponding side cooperating steel bars.

[0013] Preferably, a casting top plate is cast on the upper part of the casting bottom plate. The casting height of the casting top plate completely covers the arc-shaped covers.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

A number of groups of support frames 6 are welded and installed in the middle of the upper surface of the mating mounting plate 4, and the use height of the limit steel bars 12 is determined by the provided support frames 6. A number of groups of positioning seats 8 are symmetrically clamped and installed on both sides of the mating mounting plate 4, and the mating steel bars 11 are limited by the provided positioning seats 8. The limit of the bent connecting steel bar 14 is completed through the cooperation of the mating steel bar 11 and the limit steel bar 12; a group of mating steel bars 11 are clamped and installed on the upper part of the same-side positioning seat 8, a group of limit steel bars 12 are inserted at the top end of the support frame 6, a number of groups of arc-shaped cover plates 13 are equidistantly placed on the upper part of the limit steel bars 12, and two groups of bent connecting steel bars 14 are symmetrically welded and installed on both sides of each group of arc-shaped cover plates 13. The provided arc-shaped cover plates 13 are used to connect the two groups of bent connecting steel bars 14, and the convenience of using the bent connecting steel bar 14 is improved through the cooperation of the arc-shaped cover plate 13 and the limit steel bar 12, and the bent connecting steel bar 14 is used to weld the mating steel bar 11 and the limit steel bar 12 to further improve the service strength of the composite slab.

[0025] Preferably, a number of groups of connecting slots 3 are equidistantly arranged on the upper surface of the reinforcing plate 2. A positioning plug 5 is fixedly installed at the center of the bottom of the mating mounting plate 4. The positioning plug 5 is hermetically inserted into the connecting slot 3. The connecting slot 3 provided on the upper surface of the reinforcing plate 2 cooperates with the positioning plug 5 at the bottom of the mating mounting plate 4, enabling the mating mounting plate 4 to be more conveniently inserted into the upper part of the reinforcing plate 2, and further quickly determining the installation and welding positions of the groups of mating steel bars 11, limiting steel bars 12 and bent connecting steel bars 14, thereby improving the convenience of the overall welding of the laminated plate.

[0026] Furthermore, the mating mounting plate 4 is corrugated. The bottom of the mating mounting plate 4 is attached to the upper surface of the reinforcing plate 2. A set of limiting sleeves 7 are respectively installed at the top of each group of support frames 6. The support frames 6 welded inside the mating mounting plate 4 can be replaced according to specific usage requirements to adjust the use height of the limiting steel bars 12, and thus change the overall pouring thickness of the laminated plate.

The end of each group of bent connecting steel bars 14 is welded to fit the outer arc surface of the corresponding side mating steel bar 11. Since the arc-shaped cover plate 13 limits the bent connecting steel bars 14, workers can take multiple sets of structures at one time. By placing the arc-shaped cover plate 13, the use position of the bent connecting steel bars 14 can be determined, and the continuous limitation of the bent connecting steel bars 14 can be dispensed with, making it more convenient for workers to weld the bent connecting steel bars 14, thereby fixing the positions of the mating steel bars 11 and the limiting steel bars 12.

[0030] In addition, a pouring top plate 15 is poured on the upper part of the pouring bottom plate 1. The pouring height of the pouring top plate 15 completely covers the arc-shaped cover plate 13. The poured pouring top plate 15 covers the arc-shaped cover plate 13, protecting all the welded structures with the pouring top plate 15, thereby further improving the overall use strength of the laminated plate.
