Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum-clad wood doors and windows, and in particular to an integrated waterproof and moisture-proof structure for aluminum-clad wood doors and windows. Background Technology
[0002] Using a unique structure, aluminum alloy profiles are tightly combined with solid wood through mechanical connection or special process. Usually, a layer of aluminum alloy is wrapped around the outside of solid wood doors and windows to form a double composite structure, which gives full play to the advantages of both wood and aluminum alloy. Due to the participation of wood materials, the environment in which aluminum-clad wood doors and windows are used needs to be waterproof and moisture-proof.
[0003] Existing technologies use sealing strips to isolate external moisture. However, in practice, the isolated moisture can remain at the sealing point for extended periods, eventually seeping into the room and creating a damp environment that corrodes the wood. Therefore, existing technologies need improvement. We propose an integrated waterproof and moisture-proof structure for aluminum-clad wood doors and windows. Summary of the Invention
[0004] In order to overcome the shortcomings of the existing technology, the purpose of this utility model is to provide an integrated waterproof and moisture-proof structure for aluminum-clad wood doors and windows. By setting up multiple layers of isolation and setting up a drainage mechanism, the moisture at the isolation point can be discharged to the outside to create a dry indoor environment.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution:
[0006] An integrated waterproof and moisture-proof structure for aluminum-clad wood doors and windows includes an outer frame mechanism, a window mechanism movably installed on the inner side of the outer frame mechanism, and a drainage mechanism provided at the bottom of the inner end of the outer frame mechanism.
[0007] The drainage mechanism includes a frame, a second fitting block is provided on the upper front side of the frame, a second drain outlet is provided at the end of the second fitting block, a connecting plate is installed on the side of the second fitting block, a first fitting block is connected to the end of the connecting plate, a first drain outlet is provided at the end of the first fitting block, a baffle is fixedly installed on the upper front side of the frame, a drainage channel is provided at the bottom of the inner end of the frame, and a water outlet is provided at the end of the drainage channel. By setting multiple sets of fittings to prevent the formation of multiple protective layers, and a drainage channel is set below the protective layers, water droplets or water vapor can be collected in the protective layers and discharged to the outside, solving the problem of water vapor being blocked at the isolation layer for a long time and unable to be discharged.
[0008] Furthermore, the outer frame mechanism includes an outer frame body, and an aluminum cladding is provided on the front side of the outer end of the outer frame body. By providing an aluminum cladding on the outside, the good corrosion resistance of aluminum can provide good protection for the window part exposed to the outside.
[0009] Furthermore, the window mechanism includes a window frame, a window steel frame is fixedly installed at the front end of the window frame, a second waterproof layer is fixedly installed on the outer periphery of the front end of the window steel frame, an assembly layer is fixedly connected to the middle of the front end of the window steel frame, and a first waterproof layer is fixedly installed on the outer periphery of the front end of the assembly layer. By setting up a multi-layer structure that fits the frame, multiple protective layers are formed to improve the waterproof performance of the device during use.
[0010] Furthermore, both the first and second drain outlets are connected to a drainage channel, which is connected to a water outlet. By setting multiple drain outlets, water isolated by multiple protective layers can be discharged, avoiding the accumulation of water over a long period of time and the resulting damp environment.
[0011] Furthermore, the connection method between the connecting plate and the first mating block and the second mating block is welding.
[0012] Furthermore, the number of the baffle, the first mating block, and the second mating block are all two, and they are all installed symmetrically on the upper and lower sides of the inner end of the outer frame body.
[0013] Furthermore, the water outlet is located on the lower front side of the aluminum cladding.
[0014] Furthermore, the first mating block is adapted to the dimensions of the assembly layer, and the second mating block is adapted to the dimensions of the window frame steel frame.
[0015] Furthermore, the outer frame body and the window border are made of solid wood.
[0016] In summary, this utility model has the following beneficial effects:
[0017] 1. By setting up multiple sets of fitting protective layers to prevent the formation of multiple protective layers, and setting up drainage channels below the protective layers, water droplets or water vapor can be collected in the protective layers and flow out to the outside, solving the problem of water vapor being blocked at the isolation layer for a long time and unable to be discharged.
[0018] 2. By setting an aluminum cladding layer on the outside, the excellent corrosion resistance of aluminum can provide good protection for the window parts exposed to the outside. In addition, by setting a multi-layer structure that fits the frame, multiple protective layers are formed to improve the waterproof performance of the device. At the same time, multiple drainage outlets are set to drain the water isolated by multiple protective layers, avoiding the accumulation of water over a long period of time and the formation of a humid environment.

[0026] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.
[0027] Reference Figure 1-5 As shown, an integrated waterproof and moisture-proof structure for aluminum-clad wood doors and windows includes an outer frame mechanism 1, a window mechanism 2 movably installed on the inner side of the outer frame mechanism 1, and a drainage mechanism 3 provided at the bottom of the inner end of the outer frame mechanism 1.
[0028] The drainage mechanism 3 includes a frame 301. A second engaging block 302 is provided on the upper front side of the frame 301. A second drain outlet 303 is provided at the end of the second engaging block 302. A connecting plate 304 is installed on the side of the second engaging block 302. A first engaging block 305 is connected to the end of the connecting plate 304. A first drain outlet 306 is provided at the end of the first engaging block 305. A baffle 307 is fixedly installed on the upper front side of the frame 301. A drainage channel 308 is provided at the bottom of the inner end of the frame 301. A water outlet is provided at the end of the drainage channel 308. The connection between the connecting plate 304 and the first mating block 305 and the second mating block 302 is welded. The number of baffles 307, the first mating block 305 and the second mating block 302 are two, and they are installed symmetrically on the upper and lower sides of the inner end of the outer frame body 101. By setting multiple sets of mating, multiple protective layers are formed, and a drainage channel 308 is set below the protective layer, so that water droplets or water vapor can be collected in the protective layer and discharged to the outside. This solves the problem that water vapor is blocked at the isolation layer for a long time and cannot be discharged.
[0029] Reference Figure 1-2 As shown, the outer frame mechanism 1 includes an outer frame body 101. An aluminum cladding 102 is provided on the front side of the outer end of the outer frame body 101. The outer frame body 101 and the window frame 201 are made of solid wood. By providing an aluminum cladding 102 on the outside, the good corrosion resistance of aluminum can provide good protection for the window parts exposed to the outside.
[0030] Reference Figure 1-5 As shown, the window mechanism 2 includes a window frame 201, a window steel frame 202 fixedly installed at the front end of the window frame 201, a second waterproof layer 203 fixedly installed on the outer periphery of the front end of the window steel frame 202, an assembly layer 204 fixedly connected to the middle of the front end of the window steel frame 202, a first waterproof layer 205 fixedly installed on the outer periphery of the front end of the assembly layer 204, a first fitting block 305 adapted to the size of the assembly layer 204, and a second fitting block 302 adapted to the size of the window steel frame 202. By setting up a multi-layer structure that fits the frame, multiple protective layers are formed to improve the waterproof performance of the device during use.
[0031] Reference Figure 2-5 As shown, the first drain outlet 306 and the second drain outlet 303 are both connected to the drainage channel 308. The drainage channel 308 is connected to the water outlet 309. The water outlet 309 is located on the lower front end of the aluminum cladding 102. By setting multiple drain outlets, the water isolated by multiple protective layers can be discharged, avoiding the accumulation of water over a long period of time and the resulting humid environment.
[0032] Specific implementation process: During installation, the aluminum cladding 102 is facing outwards, and the outer frame body 101 is fixedly installed on the wall where it is to be installed.
[0033] When in use, the window is closed. The first mating block 305 fits into the assembly layer 204 and forms the first isolation layer under the action of the first waterproof layer 205. The second mating block 302 fits into the window frame 202 and forms the second isolation layer under the action of the second waterproof layer 203. A first drain outlet 306 is provided at the bottom of the first isolation layer. When water vapor reaches the first isolation layer, it gathers here and flows into the drainage channel 308 through the first drain outlet 306, and finally flows to the outlet 309 through the drainage channel 308 to be discharged.
[0034] Furthermore, when rainfall is heavy, moisture will seep in from the first isolation layer, reach the second isolation layer, and flow out in the same manner as described above, thus ensuring a dry indoor environment.
