Description

Technical Field

[0001] The utility model relates to the field of building decoration engineering, and particularly relates to a supporting and fixing structure for the decorative surface of the building external corner Background Art

[0002] For the decoration of structures such as the wall surface and supporting columns of buildings, dry-hanging decorative panels are a commonly used decoration method, and common ones include dry-hanging stone slabs, dry-hanging enamel metal panels, and so on.

[0003] A supporting keel structure is arranged on the back of the dry-hanging decorative panel, and then the decorative panel is installed on the supporting keel through hanging pieces. Generally, the keel structure is directly fixed to the wall or supporting column through angle codes and bolts.

[0004] In general, the main keel that bears the main force in the keel structure is relatively long, usually as long as the height of the decorative surface. However, the accuracy during the construction of the main structure of the building is generally not very high, and the surface of the wall or supporting column of the main building structure will present a slightly curved surface. The entire main keel is fixed to the wall or supporting column through multiple angle codes. In this way, the main keel will bend along with the curvature of the surface of the wall or supporting column. Thus, deformation stress will be generated on the keel, and some angle codes and the bolts connecting the angle codes to the main building will be subjected to greater stress. Summary of the Utility Model

[0005] In view of the above deficiencies or defects in the prior art, the utility model provides a supporting and fixing structure for the decorative surface of the building external corner. The decorative structure is simple in construction and installation, has high bearing capacity, and can be used to support heavy decorative materials such as dry-hanging stone slabs.

[0006] A supporting and fixing structure for the decorative surface of the building external corner includes an L-shaped bearing plate arranged along the building external corner. The two surfaces of the bearing plate are respectively fixed on the building surfaces on both sides of the external corner. A plurality of angle codes are arranged on the bearing plate, the main keel is fixed on the angle codes, and a fastener is fixed on the main keel, and the decorative panel is fixed on the fastener.

[0007] The main keel is arranged along the extension direction of the bearing plate, and the main keel is composed of a plurality of keel segments connected end to end.

[0008] A gap is left between the bearing plate and the building surface. A plurality of cushion plates are arranged on the inner surface of the bearing plate. The cushion plates press on the building surface, and the cushion plates separate the building surface and the bearing plate.

[0009] In some embodiments, a plurality of fixing bolts are arranged on both surfaces of the bearing plate, and the bearing plate is fixed to the main building through the fixing bolts; the fixing bolts are arranged at intervals along the extension direction of the bearing plate.

[0010] In some embodiments, the extension length of the bearing plate is the same as the length of the decorative surface; the bearing plate penetrates through the entire decorative surface.

[0011] In some embodiments, the bearing plate is made by bending the same metal sheet into a right angle.

[0012] In some embodiments, the backing plate is a rubber gasket, and the backing plates correspond to the fixing bolts one by one. The fixing bolts pass through the backing plates. One side of the backing plate is closely attached to the inner surface of the bearing plate, and the other side is closely attached to the building surface.

[0013] In some embodiments, the backing plate is a metal strip welded to the surface of the bearing plate close to the building. The metal strip is arranged parallel to the extension direction of the bearing plate and its length is the same as that of the bearing plate.

[0014] The through holes on the bearing plate for the fixing bolts to pass through are arranged at the corresponding positions of the backing plates, and the fixing bolts penetrate through the backing plates.

[0015] In some embodiments, the corner bracket is fixed to the bearing plate through mounting bolts, and the bolt head of the mounting bolt is located at the gap between the bearing plate and the building surface.

[0016] Applying the above technical solution of the present utility model to a support and fixing structure for a building external corner decorative surface has the following effects:

[0017] The present utility model changes the original connection method of directly installing the main keel to the building main body through angle steel. An L-shaped bearing plate is arranged at the external corner position of the building, and the bearing plate is stuck at the external corner position of the building. Then the main keel is connected to this bearing plate through the corner bracket. The bearing plate bears the force of the main keel. At the same time, the main keel is split into multiple keel segments. The length of each keel segment is shorter. Even if the precision of the external corner of the building main body is low, large deformation will not occur on the keel. After the keel is shortened, a small amount of bending can be eliminated through its own elastic deformation. At the same time, a backing plate is arranged on the back surface of the bearing plate. The backing plate lifts the bearing plate away from the building surface, reducing the influence of the unevenness of the building surface on the bearing plate. And the folded corner of the bearing plate itself is provided with an arc transition section. By lifting the bearing plate away from the building external corner through the backing plate, interference between the arc transition section and the building external corner can be avoided.

[0018] Other features and advantages of the present utility model will be described in detail in the subsequent specific implementation part. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following provides a detailed description of the specific embodiments of the present invention. It should be understood that the specific embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0031] In the present invention, unless otherwise stated, the orientation terms such as "upper" and "lower" generally refer to the orientation in the assembled and used state. "Inner" and "outer" refer to the inside and outside relative to the contour of each component itself.

[0032] It should be noted that the terms "first", "second", etc. in the description and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged under appropriate circumstances, so as to implement the embodiments of the present invention described herein. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion. For example, a process, method, system, product or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0033] In the present invention, a support and fixing structure for the decorative surface of the outer corner 1a of a building is provided, which includes an L-shaped bearing plate 2 arranged along the outer corner 1a of the building. The two surfaces of the bearing plate 2 are respectively fixed on the building surfaces on both sides of the outer corner 1a. A number of angle codes 3 are arranged on the bearing plate 2, a main keel 4 is fixed on the angle code 3, a fastener is fixed on the main keel 4, and a decorative plate 5 is fixed on the fastener. In this application, there is no difference from the prior art in how the decorative plate 5 is installed on the main keel 4. There are mature designs for the existing dry-hanging decorative plates 5, and reference can also be made to the attached drawings of this application Figure 1. Generally, the secondary keel is connected to the main keel 4 by bolts or connectors, and then fasteners are provided on the secondary keel, and the decorative panel 5 can be installed on the corresponding fasteners.

[0034] The best application scenario of this application is the vertical building external corner 1a. For example, the vertical external corner 1a of the wall, or the edge of the support column between floors. Usually, these external corners 1a are right angles. If not, only the bearing plate 2 needs to be adjusted adaptively according to the angle of the external corner 1a. Hereinafter, this application will be described for the case of a right angle.

[0035] The main keel 4 is arranged along the extension direction of the bearing plate 2, and the main keel 4 is composed of multiple keel segments connected end to end. The bearing plate 2 is fixed at the external corner 1a of the building to form a stable and solid installation platform. The main keel 4 is directly connected to the bearing plate 2, and there is no need to provide a supporting force at the bottom of the main keel 4. The force on the main keel 4 can be completely transmitted to the bearing plate 2 through the angle bracket 3. Therefore, the main keel 4 does not need to be set in the form of being flush with the decorative surface and can be split into multiple segments. Each segment of the main keel 4 is respectively fixed to the bearing plate 2, and then the multiple segments of the main keel 4 are connected end to end.

[0036] There is a gap between the bearing plate 2 and the building surface. A plurality of backing plates 6 are arranged on the inner surface of the bearing plate 2. The backing plates 6 press on the building surface, and the backing plates 6 separate the building surface and the bearing plate 2. At the same time, the surface of the building body 1 is generally formed by formwork pouring, and its accuracy is related to the flatness of the formwork itself and the formwork support level. Therefore, generally, the accuracy is much lower than that of the metal parts formed by machining. Therefore, in order to solve the problem of the fitting degree between the bearing plate 2 and the surface of the building body 1 with a large difference in accuracy grade, the backing plates 6 are arranged on the inner surface of the bearing plate 2 of this application. The backing plates 6 separate the inner surface of the bearing plate 2 from the building surface. One side of the backing plate 6 is in close contact with the bearing plate 2, and the other side is in close contact with the building surface.

[0037] Specifically, as shown in Figure 2 , a plurality of fixing bolts 7 are arranged on both surfaces of the bearing plate 2, and the bearing plate 2 is fixed to the building body 1 through the fixing bolts 7; the fixing bolts 7 are arranged at intervals along the extension direction of the bearing plate 2. Here, the fixing bolts 7 can be anchor bolts embedded in the building body 1, but this requires prior design and embedding during the construction of the main structure. The requirements for the design and construction control of the whole building are relatively high. However, its advantage is large bearing capacity, no damage to the building body 1, and reduction of the process of drilling holes to install the fixing bolts 7. Preferably, the fixing bolts 7 can be chemical anchor bolts, expansion bolts or through-wall tie rods.

[0038] The extension length of the bearing plate 2 is the same as the length of the decorative surface; the bearing plate 2 runs through the entire decorative surface. Here, the fixing bolts 7 are arranged in rows, and each row of fixing bolts 7 is parallel to the corresponding external corner 1a. And multiple rows of fixing bolts 7 are arranged on the same bearing plate 2.

[0039] The bearing plate 2 is made by bending the same metal plate into a right angle. Due to the setting method of this application, even if there is an arc transition at the corner of the bearing plate 2, it will not interfere with the building external corner 1a. Therefore, a production process with lower cost can be used to produce the bearing plate 2.

[0040] Next, we give two specific implementation manners of the backing plate 6.

[0041] Embodiment 1: The backing plate 6 is a rubber gasket. The backing plate 6 corresponds to the fixing bolt 7 one by one, and the fixing bolt 7 passes through the backing plate 6. One side of the backing plate 6 is closely attached to the inner surface of the bearing plate 2, and the other side is closely attached to the building surface. The rubber gasket is in the shape of a thin sheet, and a through hole for the fixing bolt 7 to pass through is reserved in the middle.

[0042] The backing plate 6 is a metal strip welded on the surface of the bearing plate 2 close to the building. The metal strip is arranged parallel to the extension direction of the bearing plate 2 and its length is the same as that of the bearing plate 2; the through hole on the bearing plate 2 for the fixing bolt 7 to pass through is arranged at the corresponding position of the backing plate 6, and the fixing bolt 7 penetrates through the backing plate 6. The metal strip can be welded and fixed on the bearing plate 2. After the metal strip is fixed, the drilling operation of the through hole of the fixing bolt 7 is carried out. The bending work of the bearing plate 2 can be carried out finally. Here, the through hole can adopt a horizontal waist-shaped hole.

[0043] Since a gap is reserved between the bearing plate 2 and the building surface, the angle bracket 3 is fixed on the bearing plate 2 through the mounting bolt 8, and the bolt head of the mounting bolt 8 is located in the gap between the bearing plate 2 and the building surface. The traditional method is welding. If the position of the main keel 4 needs to be finely adjusted later, the angle bracket 3 needs to be cut off and welded again. However, the adjustment of this application is simpler. Only need to change the through hole of the mounting bolt 8 into a waist-shaped hole.

[0044] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all belong to the protection scope of the present invention.

[0045] In addition, it should be noted that, in the above specific embodiments, the various specific technical features described can be combined in any suitable manner without conflict. To avoid unnecessary repetition, the present invention will not separately describe various possible combination manners.

[0046] In addition, any combination can be made among various different embodiments of the present utility model, as long as it does not violate the idea of the present utility model, and it should equally be regarded as the content disclosed by the present utility model.
