Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a composite plate support connection structure. Background Art

[0002] Prefabricated non-prestressed composite slabs are important prefabricated assembly components in prefabricated assembly structural systems. At the same time, prefabricated non-prestressed composite slabs can be used as the bottom formwork of the floor slab, and can be superimposed with the cast-in-place layer above it to form a reinforced concrete slab component as a whole. The use of prefabricated non-prestressed composite slabs greatly reduces the workload of on-site formwork for the floor slab.

[0003] Due to the requirements of earthquake-resistant structure, the floor slab and the surrounding supports, such as supporting beams or walls, must be reliably connected to ensure the earthquake-resistant performance of the structure under earthquake action. Therefore, according to the structural requirements, the lower steel bars of the prefabricated non-prestressed composite slab need to extend out of the slab edge and anchor into the surrounding supports, concrete beams or shear walls, etc.

[0004] The biggest difference between a composite concrete slab and a cast-in-place concrete slab is the connection method between the lower reinforcement of the slab and the beam or wall serving as the slab support. When the prefabricated non-prestressed composite slab is assembled with the prefabricated composite beam, the lower reinforcement of the slab and the stirrups of the beam are already in place, which may cause the non-prestressed composite slab to collide with the reinforcement of the support, making it difficult to hoist the slab into place on site. Therefore, the present application proposes a composite slab support connection structure. Utility Model Content

[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] like Figure 1-Figure 4 As shown, the embodiment of the utility model proposes a composite plate support connection structure, including:

[0023] A crossbeam 1 and a composite plate 2, wherein a plurality of vertical ribs 3 are embedded in the crossbeam 1 and extend therefrom, and a plurality of transverse ribs 4 are embedded in the composite plate 2 and extend therefrom;

[0024] A connection assembly for connecting the composite plate 2 with the cross beam 1; the connection assembly includes a connection groove 6 arranged at the upper end of the cross beam 1, a connection block 7 extending downward to is fixed at the bottom of the composite plate 2, a plurality of tie bars 8 are pre-embedded and extended on the connection block 7, and the connection block 7 is installed in the connection groove 6. When the connection block 7 is installed in the connection groove 6, the bottom of the composite plate 2 abuts against the upper end of the cross beam 1, so that the composite plate 2 can be supported by the cross beam 1, and the connection groove 6 and the connection block 7 are provided to ensure that the composite plate 2 and the cross beam 1 will not be misaligned;

[0025] When the connecting block 7 is installed in the connecting groove 6, the vertical ribs 3 and the horizontal ribs 4 are staggered to avoid collision and entanglement between the vertical ribs 3 and the horizontal ribs 4. In this way, only the vertical ribs 3 and the horizontal ribs 4 need to be staggered during assembly, which also plays a guiding role in extending the connecting block 7 to the connecting groove 6.

[0026] A casting groove 5 is provided at the upper end of the beam 1, and the casting groove 5 is connected with the connecting groove 6. The connecting groove 6 is arranged on the outer side of the composite plate 2. The thickness of the connecting block 7 is less than the depth of the casting groove 5. In this way, the connecting block 7 will not block the casting groove 5, and concrete can be poured into the connecting groove 6 through the casting groove 5. By pouring concrete into the connecting groove 6, the tie rod 8 and the connecting block 7 are cast as a whole with the beam 1, thereby completing the connection between the composite plate 2 and the beam 1.
