Description

Technical Field

[0001] This utility model belongs to the technical field of building door and window installation, and specifically relates to a detailed connection structure between a window and a light steel cladding wall. Background Technology

[0002] With the increasing promotion of energy conservation and environmental protection concepts in the construction industry, light steel structure buildings are widely used due to their excellent energy-saving performance and high construction efficiency. In light steel structure buildings, the cladding walls typically utilize energy-saving materials such as metal panels and composite insulation panels. Windows, as a key component of the building facade, not only provide indoor lighting and ventilation, but their connection to the cladding walls directly affects the overall airtightness, watertightness, and thermal insulation performance of the building. However, during window installation, gaps can easily form at the junction between the window frame and the cladding walls due to material differences, thermal expansion and contraction, and construction errors, leading to heat loss and rainwater leakage.

[0003] Traditional methods rely on sealant filling, but the sealant is prone to aging and cracking, and cannot withstand long-term wind pressure deformation. In existing technologies, some solutions involve adding water-retaining panels or flashing structures, but these have problems such as complex construction, high costs, or impact on appearance, thereby affecting the building's energy efficiency and durability. Utility Model Content

[0004] In order to solve the above-mentioned problems in the prior art, namely the water seepage problem caused at the junction between the window frame and the cladding wall, this utility model provides a detailed connection structure between the window and the light steel cladding wall.

Detailed Implementation

[0028] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the invention. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] This utility model provides a detailed connection structure between a window and a light steel cladding wall, referring to... Figure 1 , Figure 2 The detailed connection structure between the window and the light steel cladding wall includes a keel 1, a window frame 2 installed on the keel 1, a waterproof board 3 installed on the window frame 2 to block the connection gap between the keel 1 and the window frame 2, and a cladding wall 4 installed on the keel 1.

[0031] The keel 1 is made of light steel keel 1, with a pre-reserved mounting opening 11 for installing the window frame 2. The window frame 2 is embedded in the mounting opening 11, and when the window frame 2 is installed in the mounting opening 11, there is a gap between the window frame 2 and the mounting opening 11 as an expansion joint, which provides room for thermal expansion and contraction between the window frame 2 and the keel 1, and can be filled with insulation material to increase the insulation effect. When the window frame 2 is installed in the mounting opening, the horizontal edge of the window frame 2 extends beyond the keel 1, so as to maintain a flush transition between the window frame 2 and the enclosure wall 4 during subsequent installation.

[0032] The window frame 2 includes a frame 21 and glass 22 mounted on the frame 21.

[0033] Reference Figure 3 , Figure 4A guide channel 5 is fixedly connected to the side of the frame 21. The guide channel 5 has a U-shaped cross-section and the channel body is inclined outward. A drainage hole 51 is opened at the bottom of the guide channel 5 to guide rainwater outward. A rubber sealing strip is installed between the guide channel 5 and the frame 21 to make the guide channel 5 and the window frame 2 tightly pressed together. The guide channel 5 is installed around the frame 21.

[0034] A flexible connector 6 is installed between the frame 21 and the mounting opening 11 of the keel 1. The flexible connector 6 is installed in the gap between the frame 21 and the mounting opening 11. It can support the window frame 2 and stabilize the window frame 2 when it is deformed by compression. The flexible connector 6 includes a base plate 61, a top plate 62 parallel to the base plate 61, and a telescopic rod 63 connecting the base plate 61 and the top plate 62. A spring 64 is sleeved on the telescopic rod 63, and the two ends of the spring 64 abut against the top plate 62 and the base plate 61. The telescopic rod 63 consists of two sections of tubing that pass through each other. The two ends of the telescopic rod 63 are fixedly connected to the top plate 62 and the base plate 61. When the base plate 61 and the top plate 62 approach each other, the telescopic rod 63 is compressed, shortening its length. Then, the spring 64 is compressed, providing reverse support to the top plate 62 and the base plate 61. When the flexible connector 6 is installed in the gap between the frame 21 and the mounting opening 11, the top plate 62 abuts against the frame 21, and the base plate 61 abuts against the keel 1, supporting the keel 1 and the window frame 2. To improve the connection strength of the flexible connector 6 and prevent it from bending, an inclined plate 65 is provided between the base plate 61 and the top plate 62. The inclined plate 65 is arranged at an angle, and the base plate 61, inclined plate 65, and top plate 62 are integrally formed, forming a Z-shape to increase the connection strength between the base plate 61 and the top plate 62. A spring 64 and a telescopic rod 63 pass through the inclined plate 65. The base plate 61, inclined plate 65, and top plate 62 are made of highly elastic metal plates such as steel sheets. Under the action of the spring 64, the gap between the top plate 62 and the base plate 61 is easily maintained, thus supporting the window frame 2. Multiple flexible connectors 6 are installed at the connection point between the window frame 2 and the mounting opening 11. These multiple flexible connectors 6 are joined together to fill the gap between the frame 21 and the mounting opening 11.

[0035] The waterproof membrane 3 is installed at the edge of the window frame 2 and is connected to the frame 21 via the drainage channel 5. During installation, the waterproof membrane 3 surrounds the frame 21. The waterproof membrane 3 includes a connecting plate 31 and a baffle 32 perpendicularly fixed to the connecting plate 31, with the edge of the baffle 32 connected to the edge of the connecting plate 31. A hook 33 is fixedly connected to the other edge of the connecting plate 31, hooking into the drainage channel 5 to connect the waterproof membrane 3 to the window frame 2. When the waterproof membrane 3 is connected, there is a gap between the baffle 32 and the keel 1 to fill the gap for installing the enclosure wall 4. After installation, a through hole aligned with the drainage hole 51 is opened on the waterproof membrane 3 to facilitate the drainage of rainwater from the drainage channel 5.

[0036] The enclosure wall 4 is bonded to the keel 1 and connected to the keel 1. When the enclosure wall 4 is installed at the installation opening 11, the enclosure wall 4 is inserted between the baffle 32 and the keel 1, filling the gap between the baffle 32 and the keel 1. The baffle 32 and the enclosure wall 4 are locked together. An anti-corrosion layer is applied to the surface of the enclosure wall 4. The enclosure wall panel abuts against the part of the frame 21 that extends beyond the installation opening 11. The anti-corrosion layer extends to the window frame 2 and is fixed with self-adhesive tape.

[0037] An elastic buffer layer 7 is set between the frame 21 and the enclosure wall 4. The elastic buffer layer 7 is filled with sealing and waterproof materials such as expanding foam, sealing strips, and waterproof and breathable membrane.

[0038] In this embodiment, the flexible connector 6 is installed between the frame 21 and the mounting opening 11 of the keel 1 to accommodate the deformation of the window frame 2 and the keel 1. A guide channel 5 is provided on the outside of the window frame 2, the channel body is inclined outward, and a drainage hole 51 is provided at the bottom to guide rainwater outward; a waterproof plate 3 is provided at the junction of the enclosure wall 4 and the window frame 2, one end of the waterproof plate 3 is embedded in the guide channel 5, and the other end is locked to the enclosure wall 4.

[0039] After the keel 1 is installed, the window frame 2 is fixed to the keel 1 with self-tapping screws through the flexible connector 6; an elastic buffer layer 7 is set in the gap between the window frame 2 and the enclosure wall 4, and the overflow part is smoothed; finally, the waterproof board 3 is installed, and the waterproof board 3 is connected to the drainage channel 5 by hook, and the connection is filled with weather-resistant sealant.

[0040] When in use, the waterproof board 3 initially blocks rainwater from flowing between the window frame 2 and the keel 1, and directs the rainwater into the guide channel 5. The rainwater is then discharged through the drainage hole 51 via the guide channel 5 to prevent rainwater from accumulating.
