[0023] In assembly, the positioning pull rod 4 of a laminated slab is inserted into the insertion hole 6 of another laminated slab, then limiting adjusting assembly is adjusted, wedge block 15 is tightly clamped into wedge groove 5 on the upper end of positioning pull rod 4, the stable connection of two laminated slabs is realized, the design improves the connection stability and assembly efficiency between laminated slabs, simultaneously facilitates on-site rapid installation and disassembly, reduces construction difficulty and cost.

[0024] The limiting adjustment assembly comprises a wedge-shaped groove 5, a long screw rod 14 and a wedge-shaped block 15. The wedge-shaped groove 5 is arranged on the outer end of the positioning pull rod 4. The wedge-shaped block 15 is slidably inserted into the groove 7. The upper end of the wedge-shaped block 15 is fixedly installed with a sliding block 12. The front and rear end walls of the sliding block 12 are provided with a strip-shaped hole 13. The inner end of the superimposed plate body 1 is provided with a circular hole 8, a connecting hole 9 and a threaded hole two 10. The centers of the circular hole 8, the connecting hole 9 and the threaded hole two 10 are located on the same horizontal line. One end of the long screw rod 14 is sequentially threaded through the connecting hole 9, the circular hole 8, the strip-shaped hole 13 and the inner wall of the threaded hole two 10. The front and rear ends of the long screw rod 14 are flush with the front and rear ends of the superimposed plate body 1, thereby fixing the sliding block 12 and the wedge-shaped block 15 and preventing them from sliding or falling out.

[0025] The limiting adjustment assembly makes the connection between the superimposed plate bodies 1 more flexible and adjustable. In use, first, the positioning pull rod 4 of one superimposed plate is inserted into the insertion hole 6 of another superimposed plate. Then, the sliding block 12 is inserted into the groove 7 and pressed downward, so that the wedge-shaped block 15 moves downward and is clamped into the wedge-shaped groove 5. At this time, under the cooperation of the wedge-shaped block 15 and the wedge-shaped groove 5, the positioning pull rod 4 and the wedge-shaped block 15 are tightly connected. Under the influence of the wedge-shaped block 15, the positioning pull rod 4 can drive the superimposed plate body 1 connected thereto to move toward the adjacent superimposed plate body 1, thereby ensuring that the two adjacent superimposed plate bodies 1 are tightly fitted and improving the installation effect of the device.

[0026] The left side of the wedge-shaped groove 5 is a first inclined surface that slopes downward. The left side of the wedge-shaped block 15 is a second inclined surface that can slide with the inclined surface of the wedge-shaped groove 5. Specifically, the first inclined surface of the wedge-shaped groove 5 and the second inclined surface of the wedge-shaped block 15 slide with each other. When the wedge-shaped block 15 is inserted into the wedge-shaped groove 5, the inclined surfaces of the two are pressed against each other, thereby achieving a fastening effect.

When two adjacent superimposed plate bodies 1 are spliced together, the overlapping grooves 2 at the upper ends of the two superimposed plate bodies 1 are connected. The front and rear ends of the overlapping grooves 2 are provided with threaded holes one 3. The left and right ends of the fixed plate 16 are located in the two overlapping grooves 2, respectively. The bolts are threaded through the side walls of the fixed plate 16 and are screwed with the inner walls of the threaded holes one 3, thereby further fixing the two superimposed plate bodies 1 together.

[0029] When the device works, firstly, the positioning pull rod 4 of one laminated slab is inserted into the insertion hole 6 of another laminated slab, the sliding block 12 is inserted into the groove 7 and is pressed downwards, the wedge-shaped block 15 is moved downwards and is clamped into the wedge-shaped groove 5, at this time, under the cooperation of the wedge-shaped block 15 and the wedge-shaped groove 5, the fastening connection of the positioning pull rod 4 and the wedge-shaped block 15 can be realized, and under the influence of the wedge-shaped block 15, the positioning pull rod 4 can drive the laminated slab body 1 connected with it to move towards the adjacent another laminated slab body 1, so that the two adjacent laminated slab bodies 1 are tightly fitted, and the installation effect of the device is improved.
