Abstract
Description
Technical Field
[0001] This utility model relates to the field of curtain wall design technology, specifically to an L-shaped groove adapter. Background Technology
[0002] In the curtain wall design, the glass columns need to be secured in the U-shaped grooves from both sides.
[0003] The existing method requires assembling the U-shaped channel and glass together on-site, followed by welding the U-shaped channel and steel profile. This is cumbersome in two ways: first, once the U-shaped channel and glass are joined, the plastic parts may be damaged during transport, compromising the waterproofing; second, the welding process involves a large amount of welding, and the heat effect can easily cause the tempered glass to crack. Utility Model Content
[0004] In view of the problems existing in the above-mentioned L-shaped groove adapter, this utility model is proposed.
[0005] Therefore, the purpose of this utility model is to provide an L-shaped groove adapter, which solves the problem of complicated operation.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] The L-shaped groove adapter includes a first L-shaped rod and a second L-shaped rod. The second L-shaped rod is provided on one side of the first L-shaped rod, and the other side of the first L-shaped rod and the second L-shaped rod are attached to each other. Threaded grooves are opened on the surface of both the first L-shaped rod and the second L-shaped rod. Two bolts are threaded in the threaded grooves. The first L-shaped rod and the second L-shaped rod are fixedly connected by bolts. Both the first L-shaped rod and the second L-shaped rod are made of stainless steel.
[0008] Preferably, a placement groove is fixedly provided on the bottom of one side of the first L-shaped rod and the top of the second L-shaped rod, and a strong adhesive layer is fixedly provided on the inner side wall of the placement groove.
[0009] Preferably, anti-slip pads are fixedly provided on the bottom of one side of the first L-shaped rod and on one side of the second L-shaped rod, and the anti-slip pads are made of rubber.
[0010] Preferably, a gasket is provided on the bottom of one side of the first L-shaped rod and on one side of the second L-shaped rod, and the gasket is a silicone pad.
[0011] Furthermore, the gasket is threadedly connected to the bolt.
[0012] The technical effects and advantages provided by this utility model in the above technical solution are as follows:
[0013] 1. This utility model replaces the U-shaped channel with an L-shaped adapter. The adapter has pre-drilled bolt holes. First, the male end of the L-shaped adapter is welded to the profile, then the tempered glass is inserted. The female end is inserted into the male end, and then tightened with screws. After bending, subsequent work can continue. The advantages of this method are: firstly, it avoids welding after the tempered glass is installed; secondly, when there is no glass, only the male end of the L-shaped adapter is welded to the profile, improving process efficiency; and thirdly, structural adhesive and rubber strips are applied after the glass is installed, resulting in good waterproofing.
[0014] 2. In this utility model, the L-shaped adapter has pre-drilled bolt holes on the first L-shaped rod and the second L-shaped rod, which allows for adjustment under glass of different sizes. It can be mass-produced in the factory in advance, reducing costs. Attached Figure Description

[0021] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.
[0022] This utility model discloses an L-shaped groove adapter.
[0023] This utility model provides, for example Figure 1-3The L-shaped groove adapter shown includes a first L-shaped rod 1 and a second L-shaped rod 2. The second L-shaped rod 2 is located on one side of the first L-shaped rod 1, and the other sides of the first L-shaped rod 1 and the second L-shaped rod 2 are fitted together. Threaded grooves 3 are formed on the surfaces of both the first L-shaped rod 1 and the second L-shaped rod 2. Two bolts 4 are threaded into the grooves 3. The first L-shaped rod 1 and the second L-shaped rod 2 are fixedly connected by the bolts 4. Both the first L-shaped rod 1 and the second L-shaped rod 2 are made of stainless steel. The L-shaped groove adapter is mainly composed of the first L-shaped rod 1 and the second L-shaped rod 2, which are fitted together on one side and both have threaded grooves 3 on their surfaces. The two bolts 4 pass through the threaded grooves 3 to achieve a fixed connection. Furthermore, both the first L-shaped rod 1 and the second L-shaped rod 2 are made of stainless steel. Stainless steel material has… With good corrosion resistance and strength, the adapter can ensure a long service life and stable structural performance in the curtain wall environment. A placement groove 5 is fixedly provided on the bottom of one side of the first L-shaped rod 1 and the top of the second L-shaped rod 2. A strong adhesive layer 6 is fixedly provided on the inner wall of the placement groove 5. The placement groove 5 can be used to place related accessories or for positioning, while the strong adhesive layer 6 enhances the fixing effect of items in the placement groove 5, preventing displacement during use and improving the overall structural stability. Anti-slip pads 7 are fixedly provided on the bottom of one side of the first L-shaped rod 1 and one side of the second L-shaped rod 2. The anti-slip pads 7 are made of rubber, which has good friction, increasing the friction between the adapter and the contacting object and preventing the adapter from slipping during installation and use. To prevent slippage, the structural stability is further ensured. Washers 8 are provided on the bottom of one side of the first L-shaped rod 1 and on one side of the second L-shaped rod 2. These washers 8 are made of silicone and are threadedly connected to the bolts 4. The silicone washers have elasticity and sealing properties. During bolt tightening, the washers 8 act as a buffer, preventing direct contact between the bolts 4 and the L-shaped rod surface, thus avoiding wear. They also enhance the sealing of the threaded connection, preventing moisture and other impurities from entering the thread groove 3 and affecting the connection strength. This L-shaped groove adapter replaces the traditional U-shaped groove with an L-shaped adapter. The adapter has pre-drilled holes for bolts 4. During installation, the male end of the L-shaped adapter is first welded to the profile, then tempered glass is inserted, followed by the female end inserted into the male end, and finally tightened with screws. Subsequent work can then proceed. This design avoids the need for steel... After the tempered glass is installed, welding is performed. The high temperatures generated during welding could cause the tempered glass to crack. This method effectively protects the tempered glass and reduces the risk of damage. Without glass, only the male end of the L-shaped adapter is welded to the profile, reducing interference factors during welding, improving process efficiency, and shortening construction time. After the glass is installed, structural adhesive and rubber strips are applied for sealing, ensuring a better seal, enhancing the curtain wall's waterproof performance, and reducing leakage. Because the L-shaped adapter has four pre-drilled bolt holes on the first L-shaped rod 1 and the second L-shaped rod 2, it can be adjusted for different glass sizes, improving its adaptability and making it suitable for various curtain wall glass installations.Meanwhile, this adapter can be mass-produced in the factory, and standardized production can reduce production costs. Furthermore, the on-site installation process is relatively simple, reducing labor and time costs associated with on-site construction.
[0024] For a more secure connection, such as Figure 3 As shown, a placement groove 5 is fixedly provided on the bottom side of the first L-shaped rod 1 and the top of the second L-shaped rod 2, and a strong adhesive layer 6 is fixedly provided on the inner side wall of the placement groove 5.
[0025] And to prevent slipping, such as Figure 2 As shown, anti-slip pads 7 are fixedly provided on the bottom of one side of the first L-shaped rod 1 and on one side of the second L-shaped rod 2. The anti-slip pads 7 are made of rubber.
[0026] To make bolt 4 more secure, such as Figure 2 As shown, a pad 8 is provided on the bottom of one side of the first L-shaped rod 1 and on one side of the second L-shaped rod 2. The pad 8 is made of silicone.
[0027] Finally, for a more stable connection, such as Figure 2 As shown, washer 8 is threadedly connected to bolt 4.
[0028] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
