Description

Technical Field

[0001] This utility model relates to the technical field of composite plate connection structure, specifically a composite plate embedded connection structure. Background Technology

[0002] Composite slabs are assembled slabs made of precast slabs and cast-in-place reinforced steel. They utilize internal grooves to enhance bonding, resulting in excellent integration. The upper half of the slab is smooth, easy to decorate, and suitable for high-rise and large-area buildings with high rigidity requirements.

[0003] When installing composite slabs, adjacent precast base slabs need to be spliced ​​together first, and then concrete is poured on top of the precast base slabs. However, there are often gaps between two adjacent composite slabs. When the upper layer of concrete is poured, the concrete is easy to leak out from the gaps between the two adjacent composite slabs. Therefore, an embedded connection structure for composite slabs is needed. Utility Model Content

[0021] Please see Figure 1-5 An embodiment of this utility model is provided: a composite plate embedded connection structure, including a connector 1, a first composite plate body 2, a second composite plate body 3 and a steel beam 4.

[0024] When the first composite plate body 2 is connected to the second composite plate body 3, the first connecting part 7 and the second connecting part 9 are respectively embedded into the embedding groove 22 opened in the connector 1, and the groove 12 is correspondingly connected to the boss 11 to play a positioning role.

[0025] A steel beam 4 is fixed to the bottom of the connector 1, and the steel beam 4 is connected to the first connecting part 7 and the second connecting part 9 by bolts 13 respectively;

[0026] The top surface of the connector 1 is evenly provided with reserved holes 6. The first connecting part 7 and the second connecting part 9 are respectively provided with a first through hole 23 and a second through hole 10. The bolt 13 passes through the first through hole 23 and the second through hole 10 and extends to the outside of the reserved hole 6.

[0027] By inserting bolts 13 into the bottom of the steel beam 4, and fixing them to the first through hole 23 and the second through hole 10 opened on the first connecting part 7 and the second connecting part 9, the first composite plate body 2 and the second composite plate body 3 are fixedly embedded in the connector 1, preventing gaps between adjacent first composite plate bodies 2 and second composite plate bodies 3, making it difficult for poured concrete to leak out from the gaps, and improving on-site installation efficiency.

[0028] The first connecting part 7 and the second connecting part 9 are respectively provided with a first reserved groove 8 and a second reserved groove 24 at the end near the connector 1, and a cavity is formed between the first reserved groove 8 and the second reserved groove 24 to allow for thermal expansion and contraction between the first composite plate body 2 and the second composite plate body 3.

[0029] The bottom of each bolt 13 is locked and fixed by a nut 16, and the side of the nut 16 closest to the steel beam 4 is tightly fitted to the steel beam 4 by a buffer pad 14.

Gaps are left between the main bodies 3 of the composite slabs to prevent concrete from leaking out and improve on-site installation efficiency. The bottom of the bolts 13 are all locked and fixed by nuts 16. The end of the nuts 16 near the steel beam 4 is tightly fitted to the steel beam 4 by buffer pads 14. The end of the buffer pads 14 near the nuts 16 is provided with a bulge 15. An arched rubber elastic element 17 is provided between the bulge 15 and the nut 16. When subjected to external force, the external force can be dispersed and buffered by the deformation and recovery performance of the elastic element 17 itself, making the connection between the first composite slab body 2 and the second composite slab body 3 more stable.
