Description

Sound insulation structure of bridge cut-off aluminum window Technical Field The utility model relates to the technical field of bridge-cut-off aluminum doors and windows, in particular to a sound insulation structure of a bridge-cut-off aluminum window. Background At present, the bridge cut-off aluminum window is a high-performance window product widely applied to modern buildings and generally comprises a frame body structure, plastic heat insulation strips, hollow glass and a sealing structure, wherein the plastic heat insulation strips often adopt nylon strips to isolate an inner frame and an outer frame to form a heat transfer circuit break so as to effectively reduce heat conduction, improve the heat insulation performance of doors and windows and achieve a good heat insulation effect. Houses near streets, stations and airports are easily interfered by external noise, so that the sound insulation and noise reduction performance of doors and windows needs to be considered. At present, in order to obtain better sound insulation and noise reduction effects, improvement is often carried out from two aspects of improving the sound insulation performance of materials or increasing sealing strips to fill up compact foaming glue and improving sealing performance. In the aspect of improving the sound insulation performance of materials, laminated glass is mostly adopted to replace hollow glass, and the aspects of increasing the thickness of aluminum alloy plate pieces, increasing the number of cavities and the like are started. However, increasing the thickness of the aluminum alloy can improve the sound insulation effect, but greatly increases the production cost, increases the number of cavities, increases the difficulty of the die and the processing technology, and causes a large cost increase. Therefore, there is a need to develop a sound insulation structure of a broken bridge aluminum window against the above-mentioned drawbacks. Disclosure of utility model The utility model aims to provide a sound insulation structure of a broken bridge aluminum window, which greatly improves the noise reduction capability of the aluminum window frame structure by compounding a glue layer and a protection plate on the outer side wall of the broken bridge aluminum window. In order to solve the technical problems, the utility model adopts the following technical scheme: According to the sound insulation structure of the bridge-cut-off aluminum window, the outer aluminum of the bridge-cut-off aluminum alloy window facing the outdoor window frame and the outer aluminum wall of the window sash are compounded with the adhesive layer and the protection plate. Furthermore, the protection plate adopts an aluminum alloy decorative plate, and the glue layer is specifically formed by compounding two layers of aluminum materials through PVB film hot pressing. Furthermore, the exposed narrow edges of the adhesive layer and the protection plate are subjected to weather-proof adhesive edge sealing treatment. Further, the thickness of the adhesive layer is not less than 0.6 mm. Furthermore, the outer aluminum wall plates of the window frame and the window sash are internally provided with silencing chambers, and silencing cotton or polyurethane foaming materials are filled in the silencing chambers. Further, the thickness of the silencing chamber is 5-8 mm. Furthermore, a plurality of injection holes are formed in the outer aluminum wall plates of the window frame and the window sash, the liquid polyurethane foaming material is injected from the injection holes, and the glue layer seals the injection holes. Furthermore, the glass of the broken bridge aluminum alloy window specifically adopts double-hollow laminated glass and the outer glass adopts laminated glass. Compared with the prior art, the utility model has the beneficial technical effects that: The utility model discloses bridge cut-off aluminum alloy window's sound insulation structure through compound glue film and guard plate on the outdoor outer wall of bridge cut-off aluminum alloy window orientation, falls the noise in the position of direct contact noise sound wave, and flexible glue film can show the inside transmission of noise reduction, and the guard plate has the guard action to the glue film, avoids glue film ageing inefficacy. According to the sound insulation structure of the bridge-cut-off aluminum window, the noise reduction capability of the aluminum window frame body structure is greatly improved through the composite adhesive layer and the protection plate on the outer side wall of the bridge-cut-off aluminum window. In addition, noise vibration of the aluminum material, particularly low-frequency noise caused by vehicle flow, can be remarkably reduced by adopting the adhesive layer of the PVB material. The edges of the protective plates can be sealed by using weather-resistant glue on the exposed narrow edges of the glue layer and the protective plates, so t
