Description
Technical Field
[0001] The utility model relates to the technical field of doors and windows, and in particular to a steel-aluminum structure skylight with a double pressure balance chamber. Background Art
[0002] Currently, the steel-aluminum composite structure opening skylights on the domestic market in China have only one sealing strip between the aluminum alloy window sash and the steel window seat.
[0003] When the outdoor air pressure of the skylight is higher than the indoor air pressure, the air on the side with higher outdoor pressure will carry heat, rain, and dust, easily penetrate the only sealing strip, and enter the indoor space on the side with lower pressure. As a result, the air tightness, water tightness, wind pressure resistance, thermal insulation, and sound insulation performance of the entire skylight are greatly attenuated, and cannot meet the corresponding grade indicators required by the national standard. Utility Model Content
[0004] In order to solve the above-mentioned problems existing in the prior art, the utility model provides a steel-aluminum structure skylight with a double pressure balance chamber, which reduces the penetration speed and penetration amount of air from the space on the higher pressure side to the space on the lower pressure side. It is suitable for buildings with relatively high requirements for air tightness, water tightness, wind pressure resistance, thermal insulation and sound insulation performance, as well as open skylights installed in buildings that need to maintain positive pressure indoors.
[0005] The purpose of the utility model can be achieved through the following technical solutions:
[0006] A steel-aluminum structure skylight with a double pressure balance chamber, comprising a window sash and a window seat, wherein the window sash and the window seat are rotatably connected;
[0007] A first sealing strip and a second sealing strip are fixedly arranged on the window sash, the first sealing strip and the second sealing strip are both located at the inner edge of the window sash, the first sealing strip is in contact with the outer side of the window seat, the second sealing strip is in contact with the horizontal surface of the upper end of the window seat, and the first sealing strip and the second sealing strip are perpendicular to each other;
[0008] A third sealing strip is fixedly arranged on the window seat, the third sealing strip is located on a vertical surface at the upper end of the window seat, the third sealing strip is in contact with the inner lower end of the window sash, and the third sealing strip and the second sealing strip are in parallel directions;
[0009] The first sealing strip and the second sealing strip are respectively arranged continuously along the four sides of the window sash and penetrate through, the third sealing strip is arranged continuously along the four sides of the window seat and penetrates through, and the second sealing strip is located within the space enclosed by the first sealing strip and the third sealing strip;
[0010] The first sealing strip and the second sealing strip constitute a first pressure balancing chamber, and the second sealing strip and the third sealing strip constitute a second pressure balancing chamber.
[0011] Furthermore, the first sealing strip, the second sealing strip and the third sealing strip are all O-shaped structures.
[0012] Furthermore, the window sash and the window seat are connected via a hinge.
[0013] Furthermore, a window opener is rotatably provided below the window seat, and the other end of the window opener is rotatably connected to the window sash, and the window opener is located in the middle of the window seat.
[0014] The beneficial effects of the utility model are:
[0015] By setting the first sealing strip, the second sealing strip and the third sealing strip, the technical effect that can be achieved is that between the pressure difference between the outdoor and indoor, the first sealing strip and the second sealing strip constitute the first pressure balance chamber, and the second sealing strip and the third sealing strip constitute the second pressure balance chamber. Each pressure balance chamber is a self-enclosed cavity, forming two isolation layers between the indoor air and the outdoor air.
[0016] When the outdoor air pressure is high and penetrates the first sealing strip into the first pressure balance chamber, due to the blocking effect of the second sealing strip, the outdoor air entering the first pressure balance chamber can no longer penetrate the second sealing strip at the same penetration speed and penetration amount, so the air pressure in the first pressure balance chamber will gradually increase due to the continuous entry of outdoor air, and finally the air pressure in the first pressure balance chamber rises to the same pressure value as the outdoor air pressure, so the pressure of the outdoor air on both sides of the first sealing strip and the air in the first pressure balance chamber reaches a balance, so that the outdoor air pressure can no longer penetrate the first sealing strip into the first pressure balance chamber, which greatly reduces the penetration amount of outdoor air that continuously penetrates the two sealing strips and continuously penetrates into the second pressure balance chamber;
[0017] When the air pressure in the first pressure balance chamber is equal to the higher outdoor air pressure, the air pressure in the first pressure balance chamber will be higher than the air pressure in the second pressure balance chamber; therefore, the air pressure in the first pressure balance chamber will penetrate the second sealing strip and enter the second pressure balance chamber. Due to the blocking effect of the third sealing strip, the air entering the second pressure balance chamber can no longer penetrate the third sealing strip at the same penetration speed and penetration amount, so the air pressure in the second pressure balance chamber will gradually increase, and finally the air pressure in the second pressure balance chamber will rise to the same value as the air pressure in the first pressure balance chamber, so the air pressure values between the outdoor air pressure, the first pressure balance chamber, the second pressure balance chamber and the indoor air pressure tend to be balanced, so that the outdoor air with higher pressure continuously penetrates three sealing strips and two pressure balance chambers and enters the room with a greatly reduced penetration amount and penetration speed, thereby greatly blocking the transmission and penetration of air, water vapor, heat and noise between indoor and outdoor, and greatly improving the air tightness, water tightness, wind pressure resistance, thermal insulation and sound insulation performance;
[0018] On the contrary, when the indoor air pressure is higher than the outdoor air pressure, the structure of three sealing strips and double pressure balance chamber can also greatly reduce the amount of indoor air pressure that continuously penetrates the three sealing strips and double pressure balance chamber and leaks to the outside, meeting the technical requirements for high indoor positive pressure.
[0019] The double pressure balance chamber structure reduces the penetration speed and amount of air from the space with higher pressure to the space with lower pressure. It is suitable for buildings with relatively high requirements for air tightness, water tightness, wind pressure resistance, thermal insulation and sound insulation, as well as for opening skylights installed in buildings that need to maintain positive pressure indoors.

[0031] Reference Figures 1 to 5 The utility model discloses a steel-aluminum structure skylight with a double pressure balance chamber, including a window sash 1 and a window seat 3. One side of the window sash 1 is rotatably connected to one side of the window seat 3, and the window sash 1 and the window seat 3 are connected by a hinge 7.
[0032] A first sealing strip 4 and a second sealing strip 5 are fixedly arranged on the window sash 1. The first sealing strip 4 and the second sealing strip 5 are both located at the inner edge of the window sash 1. The first sealing strip 4 contacts the outer side of the window seat 3, and the second sealing strip 5 contacts the horizontal surface of the upper end of the window seat 3. The directions of the first sealing strip 4 and the second sealing strip 5 are perpendicular to each other.
[0033] A third sealing strip 6 is fixedly provided on the window seat 3 . The third sealing strip 6 is located on a vertical plane at the upper end of the window seat 3 . The third sealing strip 6 contacts the inner lower end of the window sash 1 . The third sealing strip 6 and the second sealing strip 5 are parallel in direction.
[0034] The first sealing strip 4 and the second sealing strip 5 are respectively arranged continuously along the four sides of the window sash 1 and penetrate therethrough, the third sealing strip 6 is arranged continuously along the four sides of the window seat 3 and penetrates therethrough, and the second sealing strip 5 is located within the space enclosed by the first sealing strip 4 and the third sealing strip 6 .
[0035] The first sealing strip 4 , the second sealing strip 5 and the third sealing strip 6 are all O-shaped structures.
[0036] The first sealing strip 4, the second sealing strip 5 and the third sealing strip 6 form two pressure balance chambers between the pressure difference between the outdoor and indoor areas, and each pressure balance chamber is a self-enclosed cavity.
[0037] The space enclosed by the first sealing strip 4 and the second sealing strip 5 is the first pressure balance chamber, and the space enclosed by the second sealing strip 5 and the third sealing strip 6 is the second pressure balance chamber, which reduces the penetration speed and amount of air from the space with higher pressure to the space with lower pressure. It is suitable for buildings with relatively high requirements on air tightness, water tightness, wind pressure resistance, thermal insulation and sound insulation, as well as open skylights installed in buildings that need to maintain positive pressure indoors.
[0038] The function of the double pressure balance chamber is to make the pressure value in the cavity between the higher outdoor pressure value and the lower indoor pressure value, forming two transition spaces, so that the pressure difference between the higher air pressure value and the lower air pressure value can be distributed on the inner and outer sides of the first sealing strip 4, the inner and outer sides of the second sealing strip 5 and the third sealing strip 6, thereby reducing the pressure difference between the air pressure value of the space on the side with higher air pressure and the air pressure value in the cavity of the first pressure balance chamber, as well as the pressure difference between the air pressure value in the cavity of the second pressure balance chamber and the air pressure value of the space on the side with lower air pressure.
[0039] A window opener 2 is rotatably provided below the window seat 3 , and the other end of the window opener 2 is rotatably connected to the window sash 1 . The window opener 2 is located in the middle of the window seat 3 .
[0040] The working principle and use process of the utility model are as follows: when the air in the space on the side with higher outdoor air pressure penetrates the first sealing strip 4 and enters the first pressure balance chamber, the pressure value will be reduced to a certain extent.
[0041] When the air in the first pressure balance chamber tries to penetrate the second sealing strip 5 and enter the second pressure balance chamber, its pressure value will be further reduced, so that the penetration speed and penetration amount of the air in the first pressure balance chamber when penetrating the second sealing strip 5 will be significantly reduced.
[0042] When the air in the second pressure balance chamber tries to penetrate the third sealing strip 6 again, the difference between the air pressure value and the air pressure value on the side of the skylight with lower indoor air pressure will be further reduced, so that when the air in the second pressure balance chamber penetrates the third sealing strip 6, its penetration speed and penetration amount will be further greatly reduced.
[0043] When the air in the space on the higher pressure side gradually decreases in penetration amount and penetration speed between the first sealing strip 4, the second sealing strip 5 and the third sealing strip 6, it will accumulate in two independent and self-enclosed pressure balance chambers, causing the air pressure value in the pressure balance chamber to gradually increase.
[0044] When the air pressure values in the two pressure balance chambers gradually rise, and the difference between the air pressure in each pressure balance chamber and the air pressure value in the space on the higher pressure side gradually decreases, a reverse pressure will be generated on the air pressure in the space on the higher pressure side, so that the penetration speed and penetration amount of the air from the space on the higher pressure side into the cavity of the first pressure balance chamber or the second pressure balance chamber gradually decrease to a lower value, until a dynamic balance is established between the air pressures in the spaces inside and outside the first sealing strip 4, the air pressures in the spaces inside and outside the second sealing strip 5, and the air pressures in the spaces inside and outside the third sealing strip 6.
[0045] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still fall within the scope of the technical solution of the present invention.
