Description

Technical Field

[0001] The present invention relates to the technical field of building exterior wall thermal insulation, and more specifically, to a back buckle for an integrated thermal insulation board. Background Art

[0002] An integrated thermal insulation board is a new type of building exterior wall material that integrates functions such as thermal insulation, decoration, and protection, and is formed by prefabricating a thermal insulation layer, a decorative layer, and a reinforcing structure layer in a factory. Traditional integrated thermal insulation boards are usually fixed with snap fasteners. This fixing method is prone to uneven gaps and poor flatness control during the installation process, requires multiple adjustments and operations during installation, has low construction efficiency, high dependence on the skills of construction workers, and the traditional fixing method is usually installed around the perimeter of the integrated board, and problems such as inability to install lateral snaps at the positions of external corners and internal corners will be encountered during installation, greatly increasing the difficulty of controlling the gaps and construction joints of the integrated board. Summary of the Invention

[0003] Aiming at the problems existing in the prior art, the purpose of the present invention is to provide a back buckle for an integrated thermal insulation board, so that the integrated thermal insulation board is more stable when fixed on the exterior wall.

[0004] The present invention adopts the following technical solutions:

[0005] A back buckle for an integrated thermal insulation board includes a stainless steel member and a plastic housing. The stainless steel member includes a first connecting portion and a second connecting portion, the first connecting portion and the second connecting portion are perpendicular, an expansion bolt is installed on the first connecting portion, a plurality of first sawteeth are provided at both ends of the second connecting portion, a through groove is provided in the plastic housing, and a snap corresponding to the first sawteeth is provided in the plastic housing. When connecting, the front end of the second connecting portion is located in the through groove of the plastic housing, and the first sawteeth are docked with the snap.

[0006] Further, several second sawteeth are provided on the outer side of the plastic housing.

[0007] Further, the plastic housing includes a bottom plate, a top plate and two side plates. The two side plates connect the bottom plate and the top plate. Second sawteeth are provided at the upper end of a part of the top plate, a wedge portion is provided inside the top plate, and the distance between one end of the top plate provided with the second sawteeth and the bottom plate is less than the distance between the other end of the top plate and the bottom plate.

[0008] Further, a tip is provided at the front end of the second connecting portion, and the tip enters from the side away from the second sawteeth and reaches directly below the second sawteeth.

[0009] Further, the number of the first sawteeth is greater than the number of the snaps, the distance between the snaps located in the plastic housing is greater than the distance between the first sawteeth, and after the stainless steel member and the plastic housing are connected, one end of the snap is stuck between two first sawteeth.

[0010] Furthermore, there is an oblong hole at one place of the connecting part, and the expansion bolt is installed at the oblong hole.

[0011] Furthermore, the plastic sheath is of a cuboid structure.

[0012] Furthermore, fix the stainless-steel component to the wall surface through the expansion bolt, then operate the plastic sheath, and insert the stainless-steel component into the plastic sheath; align the back surface of the integrated thermal insulation board with the stainless-steel component on the wall surface, and gently press it to make the integrated thermal insulation board fit tightly with the wall surface; the buckle in the plastic sheath locks with the first serration, and as the stainless-steel component is inserted into the plastic sheath, the plastic sheath deforms, and the stainless-steel component is firmly connected to the integrated thermal insulation board.

[0013] Beneficial effects

[0014] 1. Enhance the installation stability

[0015] By combining the adhesive, the plastic sheath and the stainless-steel component, double fixation of the integrated thermal insulation board on the concrete wall surface is achieved. The tight locking design of the stainless-steel component and the plastic sheath forms a strong mutual tensile stress, significantly improving the stability and safety of the installation.

[0016] 2. Improve the connection strength

[0017] After the stainless-steel component is inserted into the plastic sheath, the second serration on the surface of the plastic sheath produces an expansion effect, increasing the contact area and contact pressure with the inside of the integrated thermal insulation board, thereby enhancing the connection strength, ensuring the firm connection between the integrated thermal insulation board and the wall surface, and reducing the risk of falling off.

[0018] 3. The construction is convenient and efficient

[0019] The present invention simplifies the construction process during installation, reducing the time and labor costs required during the installation process. The stainless-steel component and the plastic sheath are easy to operate and can be quickly fixed on the wall surface. At the same time, the use of the expansion bolt further simplifies the installation steps and improves the construction efficiency.

[0020] 4. Strong adaptability

[0021] The present invention is applicable to various concrete wall surfaces, is not limited by conditions such as the flatness and humidity of the wall surface, and has wide applicability. At the same time, the designs of the stainless-steel component and the plastic sheath can be adjusted according to specific requirements to meet the installation requirements of integrated thermal insulation boards of different specifications and weights.

[0022] 5. High durability

[0023] The combined design of the stainless-steel component and the plastic sheath has high durability and corrosion resistance, can resist the erosion of harsh weather and environmental factors, extends the service life of the integrated thermal insulation board, and reduces the maintenance and replacement costs.

[0036] 1. Scheme design

[0037] The integrated thermal insulation board 4 is installed and fixed on the concrete wall surface 5 through an adhesive, a stainless steel member 1 and a plastic housing 2. The buckle 22 inside the plastic housing locks firmly with the stainless steel member 1, and the two components form mutual tensile stress. After the stainless steel member 1 is inserted into the plastic housing 2, the serrations II 23 on the surface of the plastic housing 2 expand, increasing the contact pressure with the inside of the integrated thermal insulation board 4, firmly connecting the integrated thermal insulation board 4 and the stainless steel member 1. The stainless steel member 1 is fixed to the wall surface by an expansion bolt.

[0038] The wall surface 5 is drilled according to the snap line. The integrated thermal insulation board 4 is smeared with an adhesive mortar according to the specification requirements, and slots are cut at the corresponding positions on the back so that it can just fit into the plastic housing 2. The integrated thermal insulation board 4 with the adhesive mortar is connected to the stainless steel member 1 by pressing. Once the stainless steel member 1 is inserted, it cannot be pulled out.

The tip 122 enters the through slot 21 from the side away from the serrations II 23 and reaches directly below the serrations II 23. The tip 122 facilitates the connection between the plastic housing 2 and the stainless steel member 1.

[0047] In an embodiment of the present invention, the number of the first serrations 121 is greater than the number of the buckles 22. The spacing between the buckles 22 located inside the plastic housing 2 is greater than the spacing between the first serrations 121. After the stainless-steel member 1 and the plastic housing 2 are connected, one end of the buckle 22 is stuck between two first serrations 121.

[0048] In an embodiment of the present invention, a kidney-shaped hole 111 is provided at the first connecting portion 11, and the expansion bolt 3 is installed at the kidney-shaped hole 111. The design of the kidney-shaped hole 111 facilitates adjusting the installation position of the expansion bolt 3.

[0049] In an embodiment of the present invention, the plastic housing 2 has a cuboid structure. The cuboid structure design facilitates grooving on the integrated thermal insulation board 4 and installing the plastic housing 2.

[0050] In an embodiment of the present invention, the stainless-steel member 1 is fixed to the wall surface 5 through the expansion bolt 3, and then the plastic housing 2 is operated to insert the stainless-steel member 1 into the plastic housing 2; the back surface of the integrated thermal insulation board 4 is aligned with the stainless-steel member 1 at the wall surface 3, and gently pressed to make the integrated thermal insulation board 4 closely fit with the wall surface 5; the buckles 22 inside the plastic housing 2 are locked with the first serrations 121, and as the stainless-steel member 1 is inserted into the plastic housing 2, the plastic housing 2 deforms, and the stainless-steel member 1 is firmly connected to the integrated thermal insulation board 4.
