Description

Technical Field

[0001] The present invention relates to the technical field of walls, and in particular to a precast wall panel. Background Art

[0002] A precast wall panel is a building material that is usually prefabricated in a factory and then transported to the construction site for installation. Precast wall panels are mainly used for the wall structure of buildings and have the following characteristics:

[0003] Fast construction: Since precast wall panels are manufactured in a factory, the installation speed at the construction site is relatively fast, which can shorten the construction period;

[0004] Quality control: Wall panels produced in the factory can be manufactured in a controlled environment to ensure quality consistency;

[0005] Diversity: Wall panels of different sizes and styles can be customized according to different building requirements and design requirements;

[0006] Sound insulation and heat preservation: Many precast wall panels have good sound insulation and heat preservation properties, improving the comfort of the building.

[0007] Existing precast wall panels usually use a large number of screws for fixation during installation. To improve the installation efficiency, the following aspects can be considered: By designing larger modules, reducing the number of connection points, thereby reducing the number of screws used; Adopting connection methods such as plug-in, snap-in, and assembled types to reduce the number of screws used; Using special equipment or robots for the handling and installation of wall panels to improve the construction speed and accuracy.

[0008] To reduce the number of screws used, the present invention provides an assembled precast wall panel. Summary of the Invention

[0009] To solve the deficiencies of the prior art, the present invention provides a precast wall panel that saves screws, is easy to install, and has a stable overall structure.

[0010] To achieve the purpose of the present invention, the following scheme is proposed:

[0011] A precast wall panel includes a connecting member, two symmetrically arranged walls, two fitting members, a cover, and a decorative member.

[0012] The connecting member includes a cylinder and a base. A groove is provided at the top of the base, and the bottom of the cylinder is fixedly arranged in the groove. The inside of the cylinder is hollow and the top is open. Vertical grooves are provided at two symmetric positions on the side wall of the cylinder;

[0013] An insertion plate is provided on the inner end surface of the wall. A plurality of slots are arranged in an array in the vertical direction on the side wall of the insertion plate. The insertion plate is assembled in the corresponding vertical groove, and the inner end surface of the wall is closely attached to the outer wall of the base;

[0014] The assembly includes a support block, an inner arc-shaped vertical plate and an outer arc-shaped vertical plate both provided at the bottom of the support block. A plurality of inner arc-shaped horizontal plates are provided on one side of the inner arc-shaped vertical plate, and a plurality of outer arc-shaped horizontal plates are provided on one side of the outer arc-shaped vertical plate. The inner arc-shaped vertical plate, the inner arc-shaped horizontal plates, the outer arc-shaped vertical plate and the outer arc-shaped horizontal plates are all coaxially arranged with the cylinder. The side wall of the cylinder is accommodated between the inner arc-shaped vertical plate and the outer arc-shaped vertical plate. The inner arc-shaped horizontal plates and the outer arc-shaped horizontal plates are both assembled in the slots;

[0015] The cover is assembled on the top of the cylinder for closing the cylinder;

[0016] The decorative part includes a top plate and two sealing plates both provided at the bottom of the top plate. Convex plates are provided at both ends of the top plate. Installation grooves are provided at the angle between the inner end surface and the top surface of the wall body. The convex plates are assembled in the corresponding installation grooves, and the sealing plates are assembled between the two wall bodies.

[0017] Further, the inner arc-shaped vertical plate and the outer arc-shaped vertical plate both closely adhere to the side wall of the plug plate.

[0018] Further, the cover includes a first circular plate and a second circular plate provided at its bottom and arranged coaxially. The diameter of the first circular plate is larger than that of the second circular plate. The diameter of the second circular plate is the same as the inner diameter of the cylinder. Avoidance grooves are provided at two symmetric positions on the side wall of the cover for avoiding the support block. The top surface of the support block is flush with the top surface of the first circular plate.

[0019] Further, the inner end surface and the outer end surface of the slot are both arc-shaped surfaces. The two side walls of the inner arc-shaped horizontal plate respectively closely adhere to the inner end surface of the slot and the inner wall of the cylinder. The two side walls of the outer arc-shaped horizontal plate respectively closely adhere to the outer end surface of the slot and the outer wall of the cylinder.

[0020] Further, in the thickness direction of the wall body, the thickness of the wall body is the same as that of the base, and the bottom surface of the sealing plate closely adheres to the top surface of the base.

[0021] Further, extension plates are provided on both sides of the sealing plate. The bottom surface of the extension plate closely adheres to the top surface of the base, and the outer wall of the extension plate closely adheres to the corresponding inner end surface of the wall body.

[0022] The beneficial effects of the present invention are as follows:

[0023] 1. A large number of screws are saved during the installation of the prefabricated wall panels of the assembled type, the installation is simple, the construction period is shortened, and the overall structure of the prefabricated wall panels is stable;

[0024] 2. In the connecting piece, the vertical groove on the side wall of the cylinder is used to insert the plug plates of the two wall bodies, and the base is used to determine the specified depth at which the plug plate is inserted into the cylinder, ensuring that the inner end surface of the slot on the plug plate is located inside the cylinder and the outer end surface of the slot is located outside the cylinder, so as to facilitate the subsequent smooth installation of the assembly;

[0025] 3. The structure of the assembly is ingenious. The inner arc-shaped horizontal plates are located inside the cylinder, the outer arc-shaped horizontal plates are located outside the cylinder, and the inner arc-shaped horizontal plates and the outer arc-shaped horizontal plates are both assembled in the slots, thereby firmly connecting the wall body and the cylinder together;

[0026] 4. The cover installed on the top of the cylinder has two functions: one is to seal the cylinder, and the other is to further fix the assembly;

[0027] 5. The decorative member has two functions: one is to be used to seal the gap between two walls, and the other is to reinforce the connection state of the two walls. Description of the Drawings

Detailed Implementation Modes

[0039] As Figures 1 - 3 Shown, this embodiment provides a precast wall panel, including a connecting member 1, two symmetrically arranged walls 2, two assemblies 3, a cover 4 and a decorative member 5.

[0040] Specifically, as shown in Figure 1 and Figure 6 , the connecting member 1 includes a cylinder 11 and a base 12. A groove is provided at the top of the base 12. The bottom of the cylinder 11 is pre-fixed in the groove. The inside of the cylinder 11 is hollow, and the top of the cylinder 11 is open. Vertical grooves 111 are provided at two symmetric positions on the side wall of the cylinder 11, and the symmetric plane of the two vertical grooves 111 is also the symmetric plane of the base 12.

[0041] Specifically, as shown in Figure 5 and Figure 6 , an insertion plate 21 is provided on the inner end surface of the wall body 2. The top surface of the insertion plate 21 is lower than the top surface of the wall body 2, the bottom surface of the insertion plate 21 is higher than the bottom surface of the wall body 2, and three slots 22 are arranged in an array on the side wall of the insertion plate 21 in the vertical direction. The inner end surface and the outer end surface of the slot 22 are both arc-shaped surfaces. The insertion plate 21 is assembled in the corresponding vertical groove 111. In the thickness direction of the wall body 2, the thickness of the wall body 2 is the same as the thickness of the base 12. The inner end surface of the wall body 2 is closely attached to the outer wall of the base 12. Therefore, one function of the base 12 is to quickly determine the installation position of the wall body 2. When the inner end surface of the wall body 2 is closely attached to the outer wall of the base 12, it means that the insertion plate 21 is inserted into the cylinder 11 to a specified depth, ensuring that the inner end surface of the slot 22 is located inside the cylinder 11 and the outer end surface of the slot 22 is located outside the cylinder 11.

[0042] Specifically, as shown in Figures 8 - 10 , the fitting 3 includes a support block 31, an inner arc-shaped vertical plate 32 and an outer arc-shaped vertical plate 33 both provided at the bottom of the support block 31. Three inner arc-shaped horizontal plates 321 are provided on one side of the inner arc-shaped vertical plate 32, and three outer arc-shaped horizontal plates 331 are provided on one side of the outer arc-shaped vertical plate 33. The inner arc-shaped horizontal plates 321 and the outer arc-shaped horizontal plates 331 are in one-to-one correspondence. The radius of the inner arc-shaped horizontal plate 321 is smaller than that of the outer arc-shaped horizontal plate 331. The inner arc-shaped vertical plate 32, the inner arc-shaped horizontal plates 321, the outer arc-shaped vertical plate 33, and the outer arc-shaped horizontal plates 331 are all coaxially arranged with the cylinder 11. The bottom surface of the support block 31 is closely attached to the top surface of the cylinder 11. The inner arc-shaped vertical plate 32 is located inside the cylinder 11, and the outer arc-shaped vertical plate 33 is located outside the cylinder 11. As shown in Figure 6 and Figure 9 , both the inner arc-shaped horizontal plates 321 and the outer arc-shaped horizontal plates 331 are assembled in the slots 22. The two side walls of the inner arc-shaped horizontal plate 321 are respectively closely attached to the inner end surface of the slot 22 and the inner wall of the cylinder 11, and the two side walls of the outer arc-shaped horizontal plate 331 are respectively closely attached to the outer end surface of the slot 22 and the outer wall of the cylinder 11. The fitting 3 is used to fixedly connect the wall body 2 and the cylinder 11 together.

[0043] As shown in Figure 9 and Figure 10 , both the inner arc-shaped vertical plate 32 and the outer arc-shaped vertical plate 33 are closely attached to the side wall of the insertion plate 21. The purpose of this is to ensure that the fitting 3 is installed in the specified position.

[0044] After the assembly 3 is installed, sound insulation, heat insulation and other materials can be filled into the cylinder 11 to achieve the effects of sound insulation and heat insulation.

[0045] Specifically, as Figure 3 shown, the cover 4 is assembled on the top of the cylinder 11 for closing the cylinder 11. More specifically, as Figure 3 , Figure 7 shown, the cover 4 includes a first circular plate 41 and a second circular plate 42 provided at the bottom of the first circular plate 41. The first circular plate 41 and the second circular plate 42 are coaxially arranged. The diameter of the first circular plate 41 is larger than that of the second circular plate 42. The diameter of the second circular plate 42 is the same as the inner diameter of the cylinder 11. Avoidance grooves 43 are provided at two symmetrical positions on the side wall of the cover 4 for avoiding the support blocks 31. The top surface of the support block 31 is flush with the top surface of the first circular plate 41, and the top surface of the first circular plate 41 is lower than the top surface of the wall body 2.

[0046] As mentioned before, the inner arc-shaped vertical plate 32 and the outer arc-shaped vertical plate 33 are both closely attached to the side wall of the plug board 21 to ensure that the assembly 3 is installed in place. Therefore, its purpose is to facilitate the installation of the cover 4. Installing the cover 4 on the top of the cylinder 11 has two functions: one is to close the cylinder 11, and the other is to further fix the assembly 3.

[0047] Specifically, as Figure 1 , Figure 3 , Figure 4 shown, the decorative member 5 includes a top plate 51 and two sealing plates 52 both provided at the bottom of the top plate 51. Convex plates 53 are provided at both ends of the top plate 51. Extension plates 54 are provided on both sides of the sealing plate 52. An installation groove 23 is provided at the included angle between the inner end surface and the top surface of the wall body 2. The convex plate 53 is assembled in the corresponding installation groove 23. The sealing plate 52 is assembled between the two wall bodies 2. The bottom surface of the sealing plate 52 and the bottom surface of the extension plate 54 are both closely attached to the top surface of the base 12. The outer wall of the extension plate 54 is closely attached to the inner end surface of the corresponding wall body 2. Therefore, the decorative member 5 has two functions: one is to close the gap between the two wall bodies 2, and the other is to reinforce the connection state of the two wall bodies 2.

[0048] Installation steps of the precast wall panel:

[0049] S1. First, use the fixing tooling to fix the connector 1 to prevent the connector 1 from moving randomly;

[0050] S2. Continuously push one end of the wall body 2 with the plug board 21 towards the connector 1, and insert the plug board 21 into the vertical groove 111 of the cylinder 11 until the inner end surface of the wall body 2 is closely attached to the outer wall of the base 12, ensuring that the plug board 21 is inserted to the specified depth in the cylinder 11; use the second set of fixing tooling to fix the wall body 2;

[0051] S3. Insert an assembly 3 from the top of the cylinder 11. Note that the inner arc-shaped vertical plate 32 is inside the cylinder 11 and the outer arc-shaped vertical plate 33 is outside the cylinder 11. Then rotate the assembly 3 until both the inner arc-shaped horizontal plate 321 and the outer arc-shaped horizontal plate 331 are assembled in the slot 22, and the inner arc

[0052] -shaped vertical plate 32 and the outer arc-shaped vertical plate 33 are both in close contact with the side wall of the insertion plate 21 to ensure that the assembly 3 is installed in the specified position;

[0053] S4. Repeat S2 and S3 once to install another wall 2; fill the cylinder 11 with sound insulation, heat insulation and other materials;

[0054] S5. Assemble the cover 4 on the top of the cylinder 11 to close the cylinder 11;

[0055] S6. Finally, assemble the decorative part 5 between the two walls 2.
