DETAILED DESCRIPTION

[0019] The utility model will be further described in detail in combination with the drawings and specific embodiments:

[0020] As Figure 1 , 2 , 3 shows a laminated slab for building, including laminated slab 1 and the cross section of the grid-shaped transverse steel bar 2 and longitudinal steel bar 3 arranged inside it, characterized in that: the cross section of the reinforcing rib 4 in the cross layer is arranged in the grid combined between the transverse steel bar 2 and the longitudinal steel bar 3, the annular clamping groove 5 for connecting the adjacent laminated slab 1 is arranged on both sides of the laminated slab 1, and the double-ring type plug-in rod 6 is arranged in the annular clamping groove 5.

[0025] As Figure 1 , 3 The clamping block 11 is provided with an opening in the middle, which is the same as the cross section of the double-ring type plug-in rod 6.

[0028] The implementation principle of the laminated slab for building in the embodiment of the application is:

[0029] In the production of the laminated slab 1, the transverse steel bars 2 and the longitudinal steel bars 3 are built into a steel bar grid, and then the reinforcing bars 4 are connected and fixed between the transverse steel bars 2 and the longitudinal steel bars 3 based on the diagonal lines of the steel bar grid. This way, first of all, the steel bar grid built by the transverse steel bars 2 and the longitudinal steel bars 3 provides the laminated slab with basic tensile and compressive capacity. The transverse steel bars 2 help resist the tensile force and shear force in the transverse direction of the slab, and the longitudinal steel bars 3 play a similar role in the longitudinal direction, thereby ensuring the load-bearing capacity of the slab in the two main directions.

[0030] The reinforcing bars 4 connected diagonally in the grid further enhance the structural performance of the laminated slab. The reinforcing bars 4 can effectively limit the deformation of the grid, improve the integrity and stability of the steel bar grid, and when bearing load, the reinforcing bars 4 can share part of the tensile force and pressure, making the stress distribution more uniform and reducing the local stress concentration.

[0031] In the course of connecting the laminated slab 1 with the adjacent laminated slab 1, the adjacent laminated slab 1 is first aligned, and after alignment, the annular clamping and groove 5 on the adjacent laminated slab 1 will form a clamping and groove with a double-ring type plug-in rod 6, then the double-ring type plug-in rod 6 is inserted into the annular clamping and groove 5, and the limiting plate 10 on the double-ring type plug-in rod 6 is tightly attached to the corresponding groove 9, after tightly attaching, the threaded hole 13 on the laminated slab 1 will correspond to the through hole 12 on the double-ring type plug-in rod 6, then the threaded rod 14 is screwed into the threaded hole 13 and passes through the double-ring type plug-in rod 6 to connect and fix the laminated slab 1 and the double-ring type plug-in rod 6, after fixing, the end of the double-ring type plug-in rod 6 will pass out of the other groove 9 of the laminated slab 1, and the clamping block 11 is sleeved on the double-ring type plug-in rod 6 at its position, and the groove 9 can be plugged, at this time, the connection and fixation of the adjacent laminated slab 1 are completed, this structure enhances the tensile capacity, improves the connection stability, makes the adjacent laminated slab 1 not easy to loosen and dislocate, and is simple to construct, reduces the difficulty and time cost, can avoid cracks at the connection, and improves the waterproof performance and service life.
