Description

Technical Field

[0001] The utility model relates to the technical field of yin-yang corner structures, in particular to a connection structure for yin-yang corners of a wall. Background Art

[0002] Yin and Yang angles are a type of architectural structure. Yin angles are concave at the corners of walls, such as the angle between the top of the wall and the four walls, and are usually located indoors; while Yang angles are protruding, such as the angle formed by two walls at the corner of the corridor, and are usually located outdoors. Most of the Yin and Yang angles are 90-degree right angles. Since Yang angles are protruding, they are prone to cause certain safety hazards to people (such as easy to get hurt). Therefore, people usually wrap arc-shaped columns at Yin and Yang angles to reduce safety hazards and make the wall more beautiful.

[0003] For the installation of prefabricated wall panels, the use of Yin-Yang corner connectors is very common. However, the Yin-Yang corner connectors currently on the market usually design the Yin-Yang corner connectors and the Yang-Yang corner connectors separately.

[0026] refer to Figure 1-4 The utility model provides a connection structure for the Yin-Yang corners of a wall, comprising a first wall panel 1, a second wall panel 2 and a Yin-Yang corner connector 3, wherein the first wall panel 1 is connected to the second wall panel 2 through the Yin-Yang corner connector 3; the Yin-Yang corner connector 3 comprises a Yin-Yang corner piece 30, a Yang-Yang corner piece 31 and a connecting piece 32, wherein the Yin-Yang corner piece 30 is connected to the Yang-Yang corner piece 31 through the connecting piece 32; both ends of the connecting piece 32 are respectively provided with a clamping groove 320, and both sides of the first wall panel 1 and the second wall panel 2 are provided with a clamping block 101, which is protruded outwardly relative to the first wall panel 1 and the second wall panel 2; the clamping block 101 can be inserted into the clamping groove 320 to connect the first wall panel 1 and the second wall panel 2, and when the first wall panel 1 and the second wall panel 2 are connected through the Yin-Yang corner connector 3, a Yin-Yang corner and a Yang-Yang corner are respectively formed on both sides of the connection.

[0027] The wall internal and external corner connection structure provided in this embodiment can be used in the construction of operating rooms or simple houses; the internal corner piece 30 and the external corner piece 31 are connected by the connecting piece 32, so that the internal and external corner connection piece 3 can be used on both sides, solving the problem that it is currently impossible to install internal and external corners on both sides of the wall at the same time. Figure 1 When in use, it is only necessary to insert the card block 101 on the first wall panel 1 and the second wall panel 2 into the card slot 320 of the connecting piece 32 to achieve the connection and fixation between the wall panel and the corner connector 3; the two sides of the connection mentioned in this embodiment can be specifically referred to Figure 1 , that is, it refers to the inner and outer sides of the wall panel; at the same time, the first wall panel 1 and the second wall panel 2 are detachably connected to the corner connectors 3, so that construction workers can quickly assemble the wall on site, greatly improving the installation efficiency of the wall.

[0028] Compared with the existing assembled wall panels, the connection structure for the inner and outer corners of the wall provided by the utility model has the following beneficial effects:

[0029] The technical effect of being able to simultaneously install the inner and outer corners of the wall is achieved. In the past, workers needed to install the inner and outer corners separately, which took more time and the steps were more complicated. In this embodiment, after the inner and outer corner connectors 3 are provided, it is no longer necessary to prepare the inner and outer corner accessories separately to install the inner and outer corners respectively; the materials required for installation are simpler, which greatly saves the workers' installation time, and the disassembly and assembly are very convenient, which can speed up the installation process. Moreover, the inner and outer corner connectors 3 provided in this embodiment can be compatible with the conventional R50 outer arc pieces (two-way), R50 inner arc pieces (three-way) and R50 arc pieces on the market, and have better versatility.

[0030] refer to Figure 2 and 3 In a preferred embodiment, the female corner piece 30 includes an inner arc plate 301, and the male corner piece 31 includes an outer arc plate 310. The inner walls of the inner arc plate 301 and the outer arc plate 310 are connected to the connecting piece 32. A first connecting plate 302 is provided at both ends of the inner arc plate 301, and a second connecting plate 311 is provided at both ends of the outer arc plate 310. The first connecting plate 302 is bent toward the outer arc plate 310, and the second connecting plate 311 is bent toward the inner arc plate 301.

[0031] In this embodiment, the inner wall refers to the direction toward the connecting piece 32 as the inner side, and the direction toward the connecting piece 32 as the outer side; Figure 2 and 3 When the inner arc plate 301 and the outer arc plate 310 are respectively installed with the connecting piece 32, the inner walls of the inner arc plate 301 and the outer arc plate 310 will be respectively connected with the connecting piece 32. By respectively arranging the first connecting plate 302 and the second connecting plate 311 on the inner arc plate 301 and the outer arc plate 310, the contact area between them and the connecting piece 32 can be increased, and it is also easier to install and fix them with the connecting piece 32.

[0032] refer to Figure 2 and 3In a preferred embodiment, flanges 321 are also provided on the connecting piece 32, and the flanges 321 are located on both sides of the opening of the slot 320. When the inner arc plate 301 and the outer arc plate 310 are respectively connected to the connecting piece 32, the first connecting plate 302 and the second connecting plate 311 are respectively abutted or fixedly connected to the flanges 321. In this embodiment, when the first connecting plate 302 and the second connecting plate 311 abut against the flanges 321, they mainly play the role of installation limit. At this time, the inner arc plate 301 and the outer arc plate 310 can be fixed to the connecting piece 32 by welding or other methods; the first connecting plate 302 and the second connecting plate 311 can also be fixedly connected to the flanges 321 by welding or bolts, so as to improve the overall stability between the inner arc plate 301, the outer arc plate 310 and the connecting piece 32. In this embodiment, the flanges 321 are mainly provided to limit the installation of the inner arc plate 301 and the outer arc plate 310.

[0033] refer to Figure 3 In a preferred embodiment, the inner arc plate 301 and the first connecting plate 302, the outer arc plate 310 and the second connecting plate 311 are all integrally formed. The integrally formed arrangement can make the inner arc plate 301 and the outer arc plate 310 more solid, less likely to break, and more stable.

[0034] refer to Figure 2 and 3 In a preferred embodiment, a first connecting portion 322 and a second connecting portion 323 are further provided on both sides of the connecting piece 32. The inner arc plate 301 and the outer arc plate 310 are respectively connected to the first connecting portion 322 and the second connecting portion 323. The first connecting portion 322 is arc-shaped and concave, and the second connecting portion 323 is arc-shaped and convex; and the shapes of the first connecting portion 322 and the second connecting portion 323 match the shapes of the internal corner piece 30 and the external corner piece 31, respectively.

[0035] refer to Figure 3 Here, the inner arc plate 301 is used as an example. The first connecting portion 322 is connected to the inner arc plate 301. The first connecting portion 322 is set in an arc-shaped concave shape. At this time, the inner arc plate 301 is also set in an arc-shaped concave shape. The inner referred to here can be based on the central axis of the connecting piece 32. The direction toward the central axis is inward, and the opposite is outward; so that the inner arc plate 301 can fit tightly with the connecting piece 32 (refer to Figure 2Specifically, because the internal corner piece 30 and the external corner piece 31 are connected by the connecting piece 32, it can also be understood that the connecting piece 32 supports the internal corner piece 30 and the external corner piece 31. Therefore, when the inner walls of the inner arc plate 301 and the outer arc plate 310 can be tightly matched with the connecting piece 32 (that is, the first connecting part 322 and the second connecting part 323 are in full contact with the inner arc plate 301 and the outer arc plate 310), naturally, the connecting piece 32 will provide better support for the two as a whole than when there is a gap (the existence of a gap means that when the inner arc plate 301 and the outer arc plate 310 are respectively connected to the connecting piece 32, there is a certain gap between their inner walls and the connecting piece 32, that is, incomplete contact).

[0036] refer to Figure 3 In a preferred embodiment, first folded edges 324 are formed at both ends of the first connection portion 322; second folded edges 325 are formed at both ends of the second connection portion 323, and the first folded edges 324 and the second folded edges 325 are both connected to the flange 321; when the inner arc plate 301 and the outer arc plate 310 are respectively connected to the first connection portion 322 and the second connection portion 323, the inner walls of the first connection plate 302 and the second connection plate 311 are respectively connected to the first folded edges 324 and the second folded edges 325; and are abutted against the flange 321.

[0037] like Figure 2 As shown, when the inner arc plate 301 and the outer arc plate 310 are connected to the first connection part 322 and the second connection part 323 respectively, the first connection plate 302 and the second connection plate 311 are also connected to the first folded edge 324 and the second folded edge 325, and one end of the first connection plate 302 and one end of the second connection plate 311 are also in contact with the flange 321. Figure 2 When the first connecting plate 302 is connected to the first folded edge 324, the side of the first connecting plate 302 just abuts against the side of the flange 321. Similar to the above embodiment, the first folded edge 324 and the second folded edge 325 are also tightly fitted between the first connecting plate 302 and the second connecting plate 311. The functions can be referred to the above embodiment and will not be repeated here.

[0038] refer to Figure 2 and 3 In a preferred embodiment, there are multiple connecting pieces 32, and the multiple connecting pieces 32 are arranged at intervals from top to bottom. In this embodiment, the number of connecting pieces 32 can be set according to the actual needs. By setting multiple connecting pieces 32, the support of the inner corner piece 30 and the outer corner piece 31 can be improved, and the overall stability can also be better.

[0039] refer to Figure 2In a preferred embodiment, a cavity 102 is formed between the inner corner piece 30, the outer corner piece 31 and the plurality of connecting pieces 32, and the cavity 102 is filled with thermal insulation cotton (not shown), and the thermal insulation cotton is located between two adjacent connecting pieces 32. The thermal insulation cotton mainly plays a role in heat insulation for the entire wall surface.

[0040] refer to Figure 1 and 4 In a preferred embodiment, the third wall panel 4 is further included, and the second wall panel 2 and the third wall panel 4 are connected by a yin-yang corner connector 3; there are multiple yin-yang corner connectors 3, and two adjacent wall panels are connected by the yin-yang corner connectors 3. Figure 4 The figure shows the overall assembly effect between the wall panels and the corner connectors 3. In this embodiment, the number of wall panels is only for illustration and does not represent a limitation. In actual situations, the number of wall panels to be assembled can be determined by the size of the room, the required wall width and other factors.

[0041] The connection structure for the inner and outer corners of a wall provided by the utility model realizes the connection problem between two adjacent wall panels by setting the inner and outer corner connectors 3, and also solves the problem that the inner and outer corners of a double-sided wall cannot be installed at the same time; and it is easy to disassemble and assemble, which not only improves the installation efficiency but also reduces the installation cost.

[0042] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations on the present application. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present application.
