Description

Technical Field

[0001] The invention belongs to the technical field of prefabricated buildings, and particularly relates to a splicing structure of a prefabricated concrete floor slab. Background Art

[0002] In building construction, most of the floor slabs used to be cast-in-place floor slabs, which have good overall performance, are not easy to crack on the slab surface, and have good seismic performance. However, there are also defects: the construction is complex, the construction cost is high, and the construction period is long. In view of the above defects, prefabricated concrete floor slabs have now been developed, which have the advantages of fast construction progress and less pollution at the construction site, and have broad application prospects in China; but there are also disadvantages such as small slab assembly, poor overall performance, easy cracking along the slab joints, and poor seismic performance; when assembling, reinforcement members need to be added, although effective, but there are more structures, and it will increase the construction cost. Summary of the Invention

[0003] To solve the above problems, the invention discloses a splicing structure of a prefabricated concrete floor slab, which is simple and practical in structure, fast in construction, not easy to crack on the slab surface, and has good seismic performance.

[0004] To achieve the above object, the technical solution of the invention is as follows:

[0005] A splicing structure of a prefabricated concrete floor slab includes a square module one, a square module two, and a square module three. A connecting hole one is provided on the upper plane of the square module one, and a connecting hole two is provided on the right side surface of the square module one. The square module one is arranged on the left side of the square module two, and the square module one is arranged below the square module three. A connecting hole three corresponding to the connecting hole two is provided on the left side surface of the square module two, and a connecting hole four corresponding to the connecting hole one is provided on the lower plane of the square module three. A splicing bolt one passes through the connecting hole one and the connecting hole four to connect the square module one and the square module three, and a splicing bolt two passes through the connecting hole two and the connecting hole three to connect the square module one and the square module two. The left side surface of the square module two extends upward to form the right side surface of the square module three. The upper part of the square module three is open, and the lower parts of the square module one and the square module two are open. Steel formwork is provided on the outer sides of the square module one, the square module two, and the square module three.

[0006] As an improvement of the invention, the connecting hole one and the connecting hole four are longitudinal waist-shaped holes, and the connecting hole two and the connecting hole three are waist-shaped holes in the vertical direction.

[0007] The beneficial effects of the invention are:

[0008] The splicing structure of the prefabricated concrete floor slab described in the invention firmly splices the floor slab through the connection of four surfaces in the horizontal and vertical directions, is simple and practical in structure, fast in construction, not easy to crack on the slab surface, and has good seismic performance.
