A kind of broken bridge sound insulation aluminum alloy casement window

Abstract

This application discloses a thermally broken aluminum alloy casement window, belonging to the field of doors and windows. It includes an outer frame, an inner frame installed inside the outer frame via a thermally broken strip, a side frame mounted on the inner wall of the inner frame via two hinges, a sash frame fixedly installed on one side of the side frame, and a glass assembly installed inside the sash frame. Both the inner frame and the sash frame are equipped with Helmholtz resonators. The sound insulation layer filled inside the sash frame effectively isolates external noise and reduces the impact of internal noise. At the same time, some sound energy can be absorbed by the outer tempered glass and the intermediate PVB film, while the air layer of the inner double-glazed glass can further block the transmission of sound waves. Furthermore, the Helmholtz resonator can be used to specifically absorb noise of a certain frequency.

Description

Technical Field

[0001] This application relates to the field of door and window technology, and in particular to a thermally broken soundproof aluminum alloy casement window. Background Technology

[0002] Aluminum alloy casement windows are widely used in the field of building doors and windows due to their advantages such as high strength, corrosion resistance and aesthetics. With the acceleration of urbanization, noise pollution has become increasingly prominent, which has put forward higher requirements for the sound insulation performance of doors and windows. Therefore, thermally broken soundproof aluminum alloy casement windows are needed.

[0003] Existing technologies mainly improve sound insulation performance by optimizing glass configuration, but neglect the sound insulation design of the window frame structure, resulting in unsatisfactory overall sound insulation effect. Therefore, this application proposes a thermally broken sound-insulating aluminum alloy casement window. Utility Model Content

[0010] In a preferred embodiment, the glass assembly includes an outer tempered glass layer, an intermediate PVB film, and an inner insulating glass layer, wherein the outer tempered glass layer and the inner insulating glass layer are fixedly connected by the intermediate PVB film.

[0011] By adopting the above technical solution, some sound energy can be absorbed through the outer tempered glass and the middle PVB film, while the air layer of the inner insulating glass can further block the transmission of sound waves.

[0012] In a preferred embodiment, the glass assembly is equipped with sealing strips on all four sides, and the other side of the sealing strips is fixedly connected to the inner side of the fan frame.

[0013] By adopting the above technical solution, the airtightness of the glass assembly installed on the inner wall of the fan frame can be guaranteed, ensuring that rainwater and gas will not easily penetrate.

[0014] In a preferred embodiment, a handle is installed on the side of the side frame away from the hinge, and the side frame is fitted against the outer wall of the inner frame.

[0015] By adopting the above technical solution, it is easy for users to open and close the side frame, and it is easy to apply force with the hand.

[0016] The beneficial effects of this application are:

[0017] This type of thermally broken aluminum alloy casement window effectively isolates external noise and reduces the impact of internal noise through the sound insulation layer filled inside the sash frame. At the same time, some sound energy can be absorbed by the outer tempered glass and the middle PVB film, while the air layer of the inner double-glazed glass can further block the transmission of sound waves. In addition, the Helmholtz resonator can be set up to specifically absorb noise at specific frequencies.

Detailed Implementation

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] Reference Figure 1-5 A thermally broken aluminum alloy casement window includes an outer frame 1. An inner frame 2 is installed inside the outer frame 1 via a thermally broken strip 12. A side frame 4 is rotatably installed on the inner wall of the inner frame 2 via two hinges 3. A sash frame 5 is fixedly installed on one side of the side frame 4. A glass assembly 8 is installed inside the sash frame 5. A Helmholtz resonator 10 is installed inside both the inner frame 2 and the sash frame 5.

[0027] See Figure 4 The inner wall of the fan frame 5 is provided with a cavity, and a sound insulation layer 7 is installed inside the cavity. The sound insulation layer 7 is made of polyurethane foam, which can effectively isolate external noise, reduce the impact of internal noise, and further improve the user's comfort.

[0028] See Figure 4 A rubber strip 6 is installed on the side frame 4 near the fan frame 5. The rubber strip 6 is made of polyamide nylon 66 material, with a width of 24mm and a thickness of 1.5mm, which can further block the path of sound waves transmitted through the profile.

[0029] See Figure 4 and Figure 5 The glass assembly 8 includes an outer tempered glass 801, a middle PVB film 802, and an inner insulating glass 803. The outer tempered glass 801 and the inner insulating glass 803 are fixedly connected by the middle PVB film 802, so that some sound energy can be absorbed through the outer tempered glass 801 and the middle PVB film 802, while the air layer of the inner insulating glass 803 can further block the transmission of sound waves.

[0030] See Figure 4 and Figure 5 Sealing strips 9 are installed around the glass assembly 8, and the other side of the sealing strip 9 is fixedly connected to the inner side of the sash frame 5, so as to ensure the airtightness of the glass assembly 8 installed on the inner wall of the sash frame 5, and to ensure that rainwater and gas will not easily penetrate.

[0031] See Figure 1A handle 11 is installed on the side of the side frame 4 away from the hinge 3. The side frame 4 fits against the outer wall of the inner frame 2, making it easy for the user to open and close the side frame 4 and easy to use the hand.

[0032] Working principle:

[0033] First, the outer frame 1 is installed on the wall. Then, the inner frame 2 is installed inside the outer frame 1 using the thermal break strip 12. The side frame 4 is then hinged to the inner frame 2 using the hinge 3. The glass assembly 8 is then installed inside the sash frame 5. The sealing strip 9 is then installed to seal the gap between the glass assembly 8 and the sash frame 5. The sound insulation layer 7 inside the sash frame 5 effectively isolates external noise and reduces the impact of internal noise. At the same time, some sound energy is absorbed by the outer tempered glass 801 and the intermediate PVB film 802, while the air layer of the inner insulating glass 803 further blocks the transmission of sound waves.
