Description

Technical Field

[0001] The present invention belongs to the technical field of prefabricated wall panels, and particularly relates to a prefabricated wall external corner structure and an installation method thereof. Background Art

[0002] Wall panel, also known as wainscot or wallboard, is a new type of decorative wall material developed in recent years, generally using wood as the base material. Wall panels have the advantages of light weight, fire prevention, moth prevention, safe use, obvious decorative effect, etc., so they are more and more popular among people and are used more and more widely. At present, the installation of wall panels is mostly connected to the wall by self-tapping screws or adhesives. Using screws is easy to damage the wall panel structure and the wall structure, while using adhesives to directly paste the wall panel on the wall, the chemical substances in the glue will inevitably pollute the external environment, and the environmental protection effect is poor. Moreover, when installing by these two methods, the wall panel is greatly affected by the environmental temperature. Since the thermal expansion coefficients of the wall panel and the wall are different, when the environment changes, the different expansion and contraction amounts of the wall and the wall panel are likely to cause the wall panel to deform, which will affect the decorative effect of the wall panel.

[0003] The invention with the application number CN201921048124.1 discloses an aluminum formwork external corner structure, belonging to the technical field of aluminum formwork. The external corner structure includes an external corner aluminum formwork and a flat aluminum formwork. The external corner aluminum formwork is located between two adjacent flat aluminum formworks, and the external corner aluminum formwork is set at a fixed angle; sealing plates are arranged around the back of the external corner aluminum formwork, and the first installation holes and the second installation holes are opened on the sealing plates. Through holes are arranged at one end of the flat aluminum formwork close to the external corner aluminum formwork, and the positions of the through holes correspond to the positions of the second installation holes. The two sides of the external corner aluminum formwork are respectively connected with the adjacent flat aluminum formworks through fasteners; chutes are opened on the joint surface of the flat aluminum formwork, and sliders are arranged on the external corner aluminum formwork. The sliders are fixed on the opposite sides of the external corner aluminum formwork, and the sliders are adapted to the chutes and are embedded in the chutes; the above external corner structure is a solid structure with relatively large rigidity. During the assembly process, the two sides of the external corner are easily subjected to the acting force perpendicular to the two sides of the external corner, resulting in cracking at the corner of the above external corner, leading to the scrapping of the external corner and increasing the construction cost. Summary of the Invention

Detailed implementation manner

[0024] The present invention will be further described below with reference to the accompanying drawings.

[0025] An external corner structure for prefabricated walls. This external corner structure is used for assembling at the corner of prefabricated walls. On the one hand, it is convenient to connect the vertically arranged prefabricated wall panels 2, ensuring the connection between the prefabricated wall panels of the prefabricated wall, improving the integrity and stability of the prefabricated wall. On the other hand, it increases the aesthetics of the corner of the prefabricated wall.

[0026] The external corner structure 6 is provided with insertion feet 6-1 for connecting with the prefabricated wall panel 2, improving the installation convenience of this external corner machine structure. The external corner structure 6 includes an arc-shaped external corner surface 6-6 and two insertion foot connection surfaces 6-7. The two insertion foot connection surfaces 6-7 are arranged perpendicular to each other. The two ends of the arc-shaped external corner surface 6-6 are respectively connected to the two insertion foot connection surfaces 6-7, forming a hollow external corner structure 6. To ensure the strength of the external corner structure, support members 6-2 are arranged inside the hollow external corner structure 6. The support feet 6-2 are respectively connected to the arc-shaped external corner surface 6-6 and the two insertion foot connection surfaces 6-7, for ensuring the overall strength of this external corner structure 6.

[0027] A support surface 6-8 is provided at the connection of adjacent insertion foot connection surfaces 6-7. The support member 6-2 is connected to the support surface 6-8. When the connection of the insertion foot connection surfaces 6-7 is a sharp corner, the sharp corner will push the inner side of the prefabricated wall panel 2 outwards, resulting in an angle greater than 90° between the prefabricated wall panels 2 at the external corner, affecting the aesthetics of the prefabricated wall. By changing the sharp corner structure at the connection of the insertion foot connection surfaces 6-7 to a chamfer structure through the support surface 6-8, on the one hand, it can reduce the contact area between the external corner structure 6 and the prefabricated wall panel 2, facilitating the assembly of the external corner structure 6 and ensuring the perpendicularity of the prefabricated wall panels 2 at the external corner. On the other hand, it is convenient for the support feet 6-2 to be connected to the inner wall of the external corner structure 6.

[0028] The support member 6-2 includes a deformation rib plate 6-3, a socket foot support rib plate 6-4, and a positive angle surface support rib plate 6-5. The socket foot support rib plate 6-4 and the positive angle surface support rib plate 6-5 are respectively connected to the deformation rib plate 6-3, and the socket foot support rib plate 6-4 and the positive angle surface support rib plate 6-5 are connected to the inner wall of the positive angle structure 6. During the installation process, when a relatively large force acts on the positive angle structure, the socket foot support rib plate 6-4 and the positive angle surface support rib plate 6-5 transfer the force into the deformation rib plate 6-3, causing the deformation rib plate 6-3 to deform, thereby absorbing a large amount of deformation potential energy. When the external force is removed, the deformation rib plate 6-3 rebounds, so that the positive angle structure 6 returns to its initial state, preventing the positive angle structure 6 from cracking or deforming. That is, through the structure of the support member 6-2, the toughness of the positive angle structure is improved.

[0029] In this embodiment, the deformation rib plate 6-3 is arranged at the intersection of the socket foot support rib plate 6-4 and the positive angle surface support rib plate 6-5, so as to facilitate concentrating the forces received by the socket foot support rib plate 6-4 and the positive angle surface support rib plate 6-5 on the deformation rib plate 6-3.

[0030] Two socket foot support rib plates 6-4 are connected to the deformation rib plate 6-3. The two socket foot support rib plates 6-4 are on the same plane and are respectively connected to the inner walls of the socket foot connection surfaces 6-7 on both sides. Similarly, two positive angle surface support rib plates 6-5 are connected to the deformation rib plate 6-3. The two positive angle surface support rib plates 6-5 are on the same plane and are respectively connected to the arc-shaped positive angle surface 6-6 and the support surface 6-8. Preferably, the positive angle surface support rib plate 6-5 is on the angle bisector of the two socket foot connection surfaces 6-7, ensuring that when the support member 2 is stressed, the overall force is relatively uniform, thereby further ensuring the toughness of the positive angle structure 6.

[0031] The socket foot support rib plate 6-4 is arc-shaped. The arc-shaped socket foot support rib plate 6-4 can provide two-way deformation for the two socket foot connection surfaces 6-7. That is, when the included angle between the two socket foot connection surfaces 6-7 becomes smaller, the socket foot support rib plate 6-4 bulges outwards, and when the included angle between the two socket foot connection surfaces 6-7 becomes larger, the socket foot support rib plate 6-4 is straightened, thereby further improving the toughness of the positive angle structure; the socket foot support rib plate 6-4 is arranged in parallel with the arc-shaped positive angle surface 6-6, facilitating the shaping of the positive angle structure.

[0032] The deformation rib plate 6-3 is cylindrical. The cylindrical deformation rib plate 6-3 has good elasticity, ensuring that the deformation rib plate 6-3 rebounds after being deformed by an external force, and further improving the toughness of the positive angle structure.

[0033] The bending portion is provided on the connection surface 6-7 of the insertion pin, and the bending portion forms the insertion pin 6-1, which is convenient for the forming of the insertion pin 6-1. Moreover, the insertion pin 6-1 is also in a hollow shape, so that the insertion pin 6-1 also has a certain deformation ability.

[0034] The splicing groove 2-2 for inserting the splicing member or the insertion pin 6-1 is provided on the side wall of the prefabricated wall panel 2. The splicing groove 2-2 includes a limiting groove portion 2-3, an insertion groove portion 2-4 and a movable groove portion 2-5 which are connected in sequence. When the insertion pin 6-1 is assembled, it is inserted into the limiting groove portion 2-3, and the insertion groove portion 2-4 and the movable groove portion 2-5 are used to connect the splicing member for inserting, so as to ensure that the prefabricated wall panel 2 can be connected to the external corner structure and can also be connected to the splicing member for splicing adjacent wall panels 2, ensuring the versatility of the wall panel 2.

[0035] The installation method of the above-mentioned prefabricated wall surface external corner structure includes the following steps:

[0036] S1, prefabricate the prefabricated wall panel 2 and the external corner structure 6;

[0037] S2, fix the prefabricated wall panel 2 on one side, and fix the external corner structure 6 on the assembled prefabricated wall panel 2;

[0038] S3, fix the prefabricated wall panel 2 on the other side of the external corner structure 6.

Various modifications to these embodiments will be obvious to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present invention; therefore, the present invention will not be limited to these embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
