Abstract
Description
Technical Field
[0001] This utility model relates to the field of aluminum alloy door and window technology, specifically to a soundproof aluminum alloy door and window. Background Technology
[0002] Aluminum alloy doors and windows refer to doors and windows made with aluminum alloy extruded profiles as frames, mullions, and sashes. They are often simply called aluminum doors and windows. Most office buildings and residences now have floor-to-ceiling windows, which are made of aluminum alloy profiles. However, due to the relatively simple frame structure of aluminum alloy, its sound insulation and noise reduction capabilities are relatively low, making it difficult to effectively block external environmental noise.
[0003] Traditional aluminum alloy doors and windows use single-pane glass or simple double-pane glass structures. The air cavity between the glass panes is not sealed properly, causing the insulated layer to fail and reducing sound insulation performance. In addition, the glass and aluminum alloy frame are mostly connected rigidly or sealed with a single rubber strip, allowing sound waves to be transmitted directly through the contact interface. Furthermore, air leakage from gaps leads to low-frequency noise and poor sound insulation. Utility Model Content
[0004] The purpose of this invention is to solve the problem of low sound insulation performance of traditional aluminum alloy doors and windows, and to provide a sound-insulating aluminum alloy door and window.
[0005] This utility model achieves the above-mentioned objective through the following technical solution: a soundproof aluminum alloy door and window, comprising an outer frame, wherein a fixed window located at the top and two rotating windows located at the bottom are provided within the outer frame and connected by hinges. Both the fixed window and the rotating window include a glass layer, wherein the glass layer comprises at least two layers of glass. Adjacent glass panes within the glass layer are bonded together by a first adhesive strip provided around the perimeter, and an air cavity is left between adjacent sealed glass panes. The air cavity is filled with argon gas. Aluminum alloy frames are provided on both the front and rear sides of the glass layer, and the two aluminum alloy frames enclose the glass layer. The two sides of the glass layer are bonded to the two aluminum alloy frames respectively by a second adhesive strip provided around the perimeter.
[0006] Furthermore, both the first adhesive tape and the second adhesive tape are frame-shaped adhesive tapes formed around the outer side of the glass layer for sealing and bonding.
[0007] Furthermore, the first adhesive tape is disposed between two adjacent glass pieces. The first adhesive tape includes, from the inside out, a spacer strip sandwiched between the two glass layers. Butyl adhesive is provided on both outer sides of the spacer strip, and silicone structural adhesive is provided on the outer side of the butyl adhesive. The silicone structural adhesive is fixedly bonded to the glass on both sides.
[0008] Furthermore, the second adhesive tape is disposed between the glass layer and the aluminum alloy frame, and the second adhesive tape includes a primer, silicone structural adhesive and adhesive strip between the aluminum alloy frame and the glass layer.
[0009] Furthermore, at least two stepped surfaces are provided around the outer side of the aluminum alloy frame of the rotating window, and sound-insulating cotton strips are bonded to the stepped surfaces.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] 1. The glass gaps are bonded with a three-layer adhesive tape consisting of a spacer strip, butyl sealant, and silicone sealant, forming a sealed air cavity filled with argon gas, which significantly improves the sound insulation effect for mid-to-high frequency noise; the glass and aluminum alloy frame are flexibly connected by a primer, silicone sealant, and EPDM adhesive strip, blocking rigid sound bridges and sound leakage through gaps.
[0012] 2. Stepped surfaces are installed on the outside of the rotating window frame and sound insulation strips are bonded to them. Sealing is strengthened in areas prone to sound leakage, such as hinges, to achieve balanced overall sound insulation performance of doors and windows. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0021] Combination Figures 1 to 5 The soundproof aluminum alloy door and window shown includes an outer frame 1. Inside the outer frame 1, there is a fixed window 2 at the top and two rotating windows 3 at the bottom connected by hinges. Both the fixed window 2 and the rotating window 3 include a glass layer 4. The glass layer 4 contains at least two layers of glass. Adjacent glass panes in the glass layer 4 are bonded together by a first adhesive strip 5 set around the perimeter. An air cavity 6 is left between two adjacent sealed glass panes and is filled with argon gas. Aluminum alloy frames 7 are set on both the front and rear sides of the glass layer 4. The two aluminum alloy frames 7 enclose the glass layer 4. The two sides of the glass layer 4 are bonded to the two aluminum alloy frames 7 respectively by a second adhesive strip 8 set around the perimeter.
[0022] like Figure 2-3 As shown, both the first adhesive tape 5 and the second adhesive tape 8 are frame-shaped adhesive tapes formed around the outer side of the glass layer 4 for sealing and bonding. The first adhesive tape 5 is used to bond two adjacent pieces of glass in the glass layer 4 together, and inert gases such as argon are filled into the air cavity 6 between the two pieces of glass to obtain excellent sound insulation performance. The second adhesive tape 8 is used to bond the aluminum alloy frame 7 to the glass layer 4 and fix the glass layer 4 in the aluminum alloy frame 7 on the front and rear sides. The two work together to enable the soundproof aluminum alloy doors and windows to meet the mid-to-high-end sound insulation needs, especially to have excellent isolation effect on mixed frequency bands such as traffic noise and neighborhood noise.
[0023] like Figure 5 As shown, the first adhesive strip 5 is disposed between two adjacent glass pieces. The first adhesive strip 5 includes, from the inside out, a spacer strip 51 sandwiched between the two glass layers. Butyl adhesive 52 is provided on the outer sides of both sides of the spacer strip 51, and silicone structural adhesive 53 is provided on the outer side of the butyl adhesive 52. The silicone structural adhesive 53 is fixedly bonded to the glass on both sides. The silicone structural adhesive 53 fixes the glass with high-strength adhesion and absorbs vibration energy. The butyl adhesive 52 uses low air permeability and high elasticity to prevent external moisture and dust from entering the air cavity and maintain the stability of the hollow layer. The spacer strip 51 is sandwiched between the two glass layers and is surrounded and wrapped by the butyl adhesive 52 and the silicone structural adhesive 53, forming a rigid support for the air cavity 6.
[0024] The second adhesive strip 8 is placed between the glass layer 4 and the aluminum alloy frame 7. The second adhesive strip 8 includes a primer, silicone structural adhesive, and adhesive strip between the aluminum alloy frame 7 and the glass layer 4. The primer is applied first to the inner surface of the aluminum alloy frame 7, and the metal surface is activated by the silane coupling agent to enhance the adhesion of the subsequent silicone adhesive (construction sequence: frame cleaning → applying primer → drying for 10-15 minutes). The silicone structural adhesive is applied to the frame surface after the primer treatment, directly contacting the glass edge, and serves as the main bonding material to flexibly connect the glass and the frame, while absorbing thermal expansion and contraction displacement. The adhesive strip (EPDM) is installed in the outer gap between the glass and the frame, or at the outer snap-fit position of the slot-type structure. It fills the tiny gaps through pre-compression elastic deformation, forming a physical sealing barrier to prevent rainwater and air penetration.
[0025] like Figure 4 As shown, at least two stepped surfaces 9 are provided around the outer side of the aluminum alloy frame 7 of the rotating window 3, and sound insulation cotton strips are bonded to the stepped surfaces 9; the sound insulation cotton strips further enhance the sound insulation effect of the aluminum alloy frame side and prevent sound leakage from the side.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
