Description

Sound insulation aluminum alloy door and window Technical Field The utility model relates to the technical field of aluminum alloy doors and windows, in particular to a sound insulation aluminum alloy door and window. Background The aluminium alloy door and window is made of aluminium alloy extruded section as frame, stile and leaf material. Most of the existing office buildings and houses are internally provided with floor windows, the floor windows are made of aluminum alloy sections, but because the aluminum alloy frame structure is single, the sound insulation and noise reduction functions are relatively low, and external environment noise is difficult to resist well. In addition, the glass and the aluminum alloy frame are sealed by rigid connection or single adhesive tape, sound waves are easy to be directly transmitted through a contact interface, and the problem of gap air leakage leads to low-frequency noise and poor isolation effect. Disclosure of utility model The utility model aims to solve the problem that the traditional aluminum alloy door and window has lower sound insulation performance, and provides a sound insulation aluminum alloy door and window. The sound insulation aluminum alloy door and window comprises an outer frame, wherein a fixed window positioned at the upper part and two rotating windows connected through hinges are arranged in the outer frame, the fixed window and the rotating windows comprise glass layers, the glass layers at least comprise two layers of glass, two adjacent glass layers in the glass layers are bonded and connected through first bonding belts arranged around, an air cavity is reserved between the two adjacent sealed glass layers, argon gas is filled in the air cavity, aluminum alloy frames are arranged on the front side and the rear side of the glass layers, the two aluminum alloy frames wrap the glass layers in, and the two sides of the glass layers are bonded and connected with the two aluminum alloy frames through second bonding belts. Further, the first adhesive tape and the second adhesive tape are frame-shaped adhesive zones which are formed around the periphery of the outer side surface of the glass layer and used for sealing and bonding connection. Further, the first adhesive tape is arranged between two adjacent pieces of glass, the first adhesive tape comprises a spacing bar clamped between two layers of glass from inside to outside, butyl rubber is arranged on the outer sides of two sides of the spacing bar, silicone structural adhesive is arranged on the outer sides of the butyl rubber, and the silicone structural adhesive is fixedly bonded with the two sides of glass respectively. Further, the second adhesive tape is disposed between the glass layer and the aluminum alloy frame, the second adhesive tape including a primer, a silicone structural adhesive, and a glue strip from the aluminum alloy frame to the glass layer. Further, at least two step surfaces are arranged on the periphery of the outer side surface of the aluminum alloy frame of the rotary window, and sound insulation cotton strips are bonded on the step surfaces. Compared with the prior art, the utility model has the beneficial effects that: 1.
