Description

Technical Field

[0001] This utility model relates to a building material, and more particularly to a precast slab with connectors. Background Technology

[0002] Precast slabs are a type of building material that is mass-produced and transported to various construction sites for use. If the precast slabs are made too large, they are inconvenient to transport; if they are made too small, they will not only cause inconvenience for installation but also affect the stability of the building. Summary of the Invention

[0003] To address the problems existing in the above-mentioned technologies, this utility model provides a precast panel with a connector.

[0004] A precast slab with connectors includes a top shell, a bottom shell, a first connector, and a second connector. The top shell and the bottom shell are respectively provided with a third connector on the opposite inner sides of their left and right ends. The first connector and the second connector are respectively provided on both sides of the top shell and the bottom shell. The top shell, the bottom shell, the first connector, and the second connector form a rectangular sheet material, wherein the rectangular sheet material filled with filler constitutes the precast slab with connectors.

[0005] The first connector includes a wedge-shaped recess and a first-direction clamp. The wedge-shaped recess is used for the end-to-end assembly of multiple prefabricated panels with connectors, and the first-direction clamp is used for connection with the third connector of the top shell and the bottom shell.

[0006] The third connector includes a locking chamber and an anti-disengagement hook. The locking chamber is used to store the first-direction locking head, and the anti-disengagement hook is used to hook the first-direction locking head so that it cannot be disengaged from the locking chamber.

[0007] The first connector and the second connector are configured as a wedge-shaped structure that is hinged to each other. The hinged wedge-shaped structure prevents the prefabricated panels with connectors from shaking inside and outside after being spliced ​​together, thereby enhancing their stability.

[0008] The upper and lower ends of the wedge-shaped concave head and the wedge-shaped convex head are respectively provided with a directional locking head and a tail-oriented locking head. The directional locking head includes an anti-detachment convex edge and a tightening spring piece. The anti-detachment convex edge is used to lock the anti-detachment hook.

[0009] The tail-direction and head-direction connectors facilitate the assembly of prefabricated plates with connectors.

[0010] The first U-shaped connector is the first type of connector, the second U-shaped connector is the second type of connector, and the third connector is the third type of connector.

[0011] The beneficial effects of this utility model are that it not only facilitates the installation of precast slabs, but also does not bring instability factors to buildings using precast slabs. Attached Figure Description

The described embodiments are only some embodiments of the present invention. Other embodiments obtained by those skilled in the art without creative effort are all within the protection scope of the present invention. Example 1

[0031] like Figure 1 and 2 As shown, this utility model is a precast slab with a connector.

[0032] like Figure 2 and 3 As shown, a precast slab with connectors includes a top shell 11, a bottom shell 12, a first connector 13, a second connector 14, and a filler 17. The top shell 11 and the bottom shell 12 are respectively provided with third connectors 15 on the inner sides of their left and right ends. The first connectors 13 and the second connectors 14 are respectively provided on both sides of the top shell 11 and the bottom shell 12. The top shell 11, the bottom shell 12, the first connectors 13 and the second connectors 14 form a hollow rectangular sheet-like box. Foamed cement is filled into the rectangular sheet-like box to form a foamed cement precast slab with connectors.

[0033] like Figure 4 and 7 As shown, the first connector 13 includes a wedge-shaped recess 131 and a first-direction locking head 132. The wedge-shaped recess 131 is used for the end-to-end assembly of multiple prefabricated panels with connectors. The first-direction locking head 132 is used to connect with the third connector 15 of the top shell 11 and the bottom shell 12. The second connector 14 is mirror-symmetrical to the first connector 13 and will not be described again. The configuration of the third connector 15, the tail-direction locking head 142 and the first-direction locking head 132 facilitates the assembly of prefabricated panels with connectors.

[0034] like Figure 6 and 7 As shown, the third connector 15 includes a locking chamber 151 and an anti-disengagement hook 152. The locking chamber 151 is used to store the first-direction locking head 132, and the anti-disengagement hook 152 is used to hook the first-direction locking head 132 so that it cannot be disengaged from the locking chamber 151.

[0035] like Figure 2 , 8 As shown in Figure 13, in order to accommodate buildings of different sizes, prefabricated slabs with connectors need to be spliced ​​end to end.

[0036] like Figure 4 , 5 As shown in Figure 13, in order to increase the stability of the precast slab with connectors after splicing, the first connector 13 and the second connector 14 are configured as a wedge structure that is hinged to each other to prevent the precast slab with connectors after splicing from shaking inside and outside, thereby enhancing its stability.

[0037] like Figure 2-7 As shown, in order to increase the robustness of the hinged wedge structure, the upper and lower ends of the wedge concave head 131 and the wedge convex head 141 are respectively provided with a first-direction locking head 132 and a tail-direction locking head 142. The first-direction locking head 132 includes an anti-disengagement protrusion 1321 and a tightening spring 1322. The anti-disengagement protrusion 1321 is used to lock the anti-disengagement hook 152.

[0038] like Figure 4 and 5 As shown, the tail-facing card head 142 is mirror-symmetrical to the head-facing card head 132, and its structure is the same as that of the head-facing card head 132.

[0039] like Figure 7 and 13 As shown, during assembly, the first connector 13 and the second connector 14 are placed on both sides of the top shell 11 and the bottom shell 12, respectively. The tail-direction latch 142 and the head-direction latch 132 are respectively inserted into the third connector 15 of the top shell 11 and the bottom shell 12. When the tail-direction latch 142 or the head-direction latch 132 is inserted into the engagement chamber 151, the anti-disengagement hook 152 is pressed against the inner side of the anti-disengagement protrusion 1321, so that the tail-direction latch 142 or the head-direction latch 132 cannot be disengaged again, thereby enhancing the stability of the precast plate with connectors.

[0040] like Figure 2-7 As shown, the tail-side connector 142 and the head-side connector 132 facilitate the assembly of prefabricated plates with connectors.

[0041] This foamed cement precast panel with connectors is a flame-retardant, non-toxic, environmentally friendly, and low-carbon material, which is a new type of material strongly promoted by the state. Its fire resistance reaches Class A. This product has high compressive strength, low thermal conductivity, and strong adhesion to concrete. Example 2

[0042] like Figure 8-12As shown in 14 and 16, unlike the first embodiment, the first-direction clamp 132 is a first U-shaped clamp 133, the tail-direction clamp 142 is a second U-shaped clamp 143, and the third connector 15 is a third U-shaped clamp 16. The second U-shaped clamp 143 and the third U-shaped clamp 16 are arranged in reverse order and connected by mutual insertion. The hollow rectangular sheet-like box is filled with foamed gypsum to form a foamed gypsum prefabricated board with connectors.

[0043] During assembly, the second U-shaped clips 143 are inserted from one end of the top shell 11 and the bottom shell 12 respectively, and then inserted to the other end along the length of the top shell 11 and the bottom shell 12 to form a rectangular cylindrical shell. Foamed cement is poured into the shell to make a precast panel with connectors.

[0044] like Figure 10 , 11 As shown in Figures 1 and 12, the first U-shaped card head 133 and the second U-shaped card head 143 are mirror images of each other, and will not be described again.

[0045] This precast foamed gypsum board with connectors is environmentally friendly, aesthetically pleasing, and poses no harm to the human body. It is easy to construct, process, install, and disassemble, and has good sound insulation, heat insulation, and fire resistance properties. It can create various effects according to different needs. Example 3

[0046] Unlike the first and second embodiments, the hollow rectangular sheet-like box is filled with polyurethane foam material, which has the functions of heat preservation, heat insulation and sound insulation, creating a quiet and comfortable working and living environment for people.

[0047] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
