[0002] Hollow beamless slab structures have been widely used in modern construction due to their advantages such as light weight, high strength and convenient construction. In particular, in buildings with large spans and large space structures, hollow beamless slab structures have become an indispensable structural form due to their excellent load-bearing capacity and space utilization efficiency. China has authorized a utility model patent (Announcement No.: CN219909534U) to disclose an assembled prefabricated beam-slab. By providing connecting plates and slots, multiple groups of prefabricated beam-slabs can be conveniently connected together with the connecting slots. By providing clips and clamping slots, the connection stability between the spliced ​​plate and the base plate can be increased. By providing inserts and limit slots, the connection stability between multiple groups of spliced ​​plates can be increased.

[0003] However, the above device still has some shortcomings when in use: specifically, when assembling the panels in the prior art, it is necessary to horizontally insert the card block of one panel into the card slot of another panel to achieve a stable connection between the two adjacent panels. This horizontal plug-in method can usually be carried out smoothly in open construction sites, but in some specific scenarios, such as construction sites with obstacles such as walls and columns on both sides, the horizontal plug-in method is particularly inconvenient. Therefore, a hollow beamless panel structure is proposed to address the above situation. Utility Model Content

[0009] Preferably, the horizontal bar is integrally formed with the plate body, and the horizontal bar is provided with a through-hole for threading the rope during the lifting operation.

[0010] Preferably, when the convex mounting block is assembled and connected with the assembly groove, a gap is formed between the assembly block and the adjacent plate body.

[0011] Preferably, when the convex mounting block is assembled and connected with the assembly groove, concrete is poured into the gap and the hollow groove to enhance the connection stability of the two adjacent plates.

[0012] Preferably, the plate body has a heat preservation layer and a thermal insulation layer for enhancing the heat preservation and heat insulation capabilities of the plate body.

[0013] Preferably, the thermal insulation layer is made of perlite material, and the heat insulating layer is made of silicate material.

Correspondingly, column caps and columns are provided at the bottom of the slab body 1 to support the slab body 1. Horizontal bars 3 are provided on both sides of the outer wall of the slab body 1 to assist the slab body 1 in completing the lifting operation. An assembly groove 4 is provided at one end of the slab body 1, and limiting grooves 401 are provided on both sides of the inner wall of the assembly groove 4.

[0027] An assembly block 5 is provided at one end of the plate body 1 away from the assembly groove 4. Both sides of the assembly block 5 have convex edges 501. The convex edges 501 are integrally formed with the assembly block 5 and are both made of steel. The assembly block 5 and the convex edges 501 cooperate to form a convex mounting block, which is used to cooperate with the assembly groove 4 to complete the assembly connection of two adjacent plate bodies 1. The convex mounting block has a hollow groove 502.

[0028] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 Grooves 2 are provided on both sides of the outer wall of the plate body 1, and there are two grooves 2 on each side. The horizontal bar 3 is fixed on the groove 2. The horizontal bar 3 is integrally formed with the plate body 1. A through-hole 301 is provided on the horizontal bar 3 for threading the rope during lifting operations.

[0029] In this embodiment, the horizontal bar 3 is also made of reinforced concrete structure to ensure its connection strength, thereby ensuring stability and safety during lifting operations. The perforations 301 are designed to be used in conjunction with hooks or ropes to complete lifting operations.

[0030] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 4 When the convex mounting block and the assembly groove 4 are assembled and connected, a gap 6 is provided between the assembly block 5 and the adjacent plate body 1.

The heat preservation layer is made of perlite material, and the thermal insulation layer is made of silicate material.

[0032] In this embodiment, the design of the thermal insulation layer and the heat insulating layer enables the plate body 1 to have good thermal insulation capabilities, thereby preventing thermal expansion and contraction from causing the plate body 1 to expand or contract, thereby affecting the inner wall structure of the beam plate.

[0033] Working principle: When in use, first hang the hooks on the sling on the four through-holes 301 on the plate body 1 one by one, use the sling to lift the plate body 1 to the designated construction location, remove the hook, and then hang the hook on the four through-holes 301 on another plate body 1, lift the plate body 1 to the position of the previous plate body 1, and the staff will align the assembly block 5 with the assembly groove 4 on the previous plate body 1, and then insert the assembly block 5 into the assembly groove 4 from top to bottom, and at the same time complete the cooperation between the convex edge 501 and the limit groove 401. After all the plates 1 are laid and assembled, the staff can inject concrete into the gap 6 and the hollow groove 502, and then improve the strength and stability of the connection through the solidified concrete, which helps to resist the influence of external loads and vibrations and extend the service life of the structure.
