Description

Technical Field

[0001] This invention relates to the field of composite floor slab technology, specifically to the connection structure and installation method of prefabricated composite floor slabs. Background Technology

[0002] Composite floor slabs are prefabricated monolithic floor slabs composed of precast slabs and cast-in-place reinforced concrete layers. Composite floor slabs offer good overall integrity, with smooth upper and lower surfaces facilitating finishing and making them suitable for high-rise buildings and large-span buildings requiring high overall rigidity. Their high rigidity and structural integrity also save on formwork. However, when using composite floor slabs, multiple slabs need to be spliced ​​together. Because traditional composite floor slabs lack splicing mechanisms, misalignment can easily occur when joining two slabs, affecting subsequent use.

[0003] Existing technologies have the following drawbacks: When using composite floor slabs, multiple composite floor slabs need to be spliced ​​together. Since traditional composite floor slabs lack splicing mechanisms, misalignment can easily occur when splicing two composite floor slabs, affecting subsequent use. Therefore, a prefabricated composite floor slab construction and installation method is proposed to address the above problems. Summary of the Invention

[0004] To address the problems in the prior art, this invention provides a connection structure for composite slabs, which facilitates the installation and construction of composite floor slabs.

[0005] The technical solution adopted by the present invention to solve the aforementioned problem is as follows:

[0006] A connection structure for prefabricated composite floor slabs includes two splicing slabs to be connected, a connecting device, and a sealing device. The two splicing slabs have grooves on their opposite sides. The connecting device has mounting cavities at both ends, with through openings on the outer walls of the mounting cavities. A sliding element consists of a sliding plate, inserts, and springs. The sliding plate is slidably positioned within the mounting cavity, with a spring on its inner surface. The outer end of the spring abuts against the inner wall of the mounting cavity. Several inserts are fixed to the outer surface of the sliding plate, with their outer ends penetrating the through openings and abutting against the inner wall of the grooves. A sealing device is located between the two splicing slabs to seal the gap between them.

[0007] As a preferred option, a further technical solution to the above structure is:

[0008] The placement plate has spaced supports at the midpoint of its outer ends, and the inserts are symmetrically distributed based on these spaced supports, thus balancing the forces between the placement plate and the splicing plates on both sides.

[0009] The upper wall of the installation cavity is provided with a sliding groove hole, a fixed block is installed at the position exposed by the sliding groove hole, a pull block is hinged to the upper side of the fixed block, and the pull block facilitates the movement of the sliding plate and the plug block.

[0010] The sealing device comprises a sealing plate, two insertion columns are fixedly connected to the bottom of the sealing plate, and an insertion hole is arranged on the top surface of the connecting device.

[0011] A limiting strip is further fixedly connected to the bottom of the sealing plate, and a limiting groove is further arranged on the top surface of the connecting device, and the limiting strip is inserted into the limiting groove.

[0012] The special connecting structure for floor connection has good stability and convenient connecting operation, and the sealing plate can increase the sealing property between the two spliced plates.

[0013] The application further provides a connecting structure installation method of the fabricated composite slab,

[0014] The specific steps are as follows:

[0015] Step one: a clamping groove is arranged on the side wall of the fabricated spliced plate, and an installation cavity is arranged in the inner plate;

[0016] Step two: a sliding plate is installed in the installation cavity, a plurality of springs are installed between the inner side surface of the sliding plate and the inner wall of the installation cavity, and a plurality of plug blocks are connected to the outer side surface of the sliding plate; the sliding plate is slid inward to drive the plug blocks to move inward, so that the springs are compressed; when the sliding plate is released, the springs drive the sliding plate and the plug blocks to move outward;

[0017] Step three: the upper surface of the sliding plate is fixedly connected with a fixed block, and the surface of the fixed block is rotatably connected with a pull block;

[0018] Step four: the pull block is pulled to drive the fixed block and the sliding plate to slide inward; the sliding plate is slid inward to drive the plug blocks to retract; then the clamping groove of the spliced plate is sleeved on the side of the inner plate, so that the side edge of the spliced plate is tightly attached to the side surface of the interval support;

[0019] Step five: the pull block and the sliding plate are released, the plug blocks are driven to extend out by the springs, and the outer ends of the plug blocks are inserted into the inner wall of the clamping groove, so that the spliced plate is clamped with the inner plate;

[0020] Step six: the bottom of the sealing device is inserted into the connecting device, and the sealing device is pressed into the interval between the two spliced plates.
