[0002] A building curtain wall refers to the non-load-bearing exterior wall cladding of a building. It is usually composed of panels (glass, metal, stone, and ceramic panels, etc.) and a supporting structure behind them (aluminum beams and columns, steel structures, and glass ribs, etc.). The curtain wall is the exterior wall cladding of a building, which is non-load-bearing and is hung up like a curtain, hence it is also called a suspended wall.

[0003] Existing wind pressure resistance testing devices for building curtain walls test the wind pressure resistance of the building curtain wall by installing the curtain wall to be tested on top of a sealed box and then simulating wind pressure by changing the air pressure inside the pressure box.

[0004] However, existing wind pressure resistance testing devices for building curtain walls may encounter situations where the length of the curtain wall is not uniform during installation, resulting in gaps in the installation. This means that the curtain wall may move during wind pressure resistance testing, leading to inaccurate test data. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a wind pressure resistance performance testing device for building curtain walls. This device solves the problem that during the installation of building curtain walls, the varying lengths of the curtain walls can lead to gaps in the installation, causing the curtain walls to shift during wind pressure resistance performance testing and resulting in inaccurate test data.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a wind pressure resistance performance testing device for building curtain walls, comprising a pressure chamber, a cover shell above the pressure chamber, a cover plate fixedly connected to the top of the cover shell, multiple distance sensors fixedly connected to the inner wall of the cover plate, a placement plate fixedly connected to the inner wall of the pressure chamber, a sealing plate inserted into the inner wall of the pressure chamber, the bottom of the sealing plate abutting the top of the placement plate, and a fixing bolt threadedly connected to the outer wall of the pressure chamber near the sealing plate, the bottom of the fixing bolt abutting the top of the sealing plate.

[0007] Preferably, a screw is fixedly connected to the outer wall of the pressure box, the top of the screw penetrates the top of the cover plate, and a first fixing member and a second fixing member are threadedly connected to the upper and lower parts of the outer wall of the screw, respectively, and the first fixing member and the second fixing member are located on the upper and lower sides of the cover plate, respectively.

[0011] Beneficial effects

[0012] This utility model provides a device for testing the wind pressure resistance performance of building curtain walls. It offers the following advantages: This device, through the cooperation of a placement plate, a sealing plate, and fixing bolts, allows for wind pressure resistance performance testing of building curtain walls. First, the building curtain wall is placed on top of the placement plate on the inner wall of the pressure chamber. Then, personnel adjust the position of the sealing plate on the inner wall of the pressure chamber according to the length of the building curtain wall until it is firmly against the outer wall of the building curtain wall. Finally, the sealing plate is fixed with the fixing bolts.

[0013] By coordinating a vacuum pump, an air compressor, and a shut-off valve, when testing the wind pressure resistance of a building curtain wall, the vacuum pump is first started. The vacuum pump extracts the air from the pressure chamber and, after continuous operation, lowers the pressure inside the chamber than the external pressure, allowing for a negative pressure test on the curtain wall. Once the negative pressure test is complete, the air compressor is started. The air compressor's operation raises the pressure inside the chamber to a level greater than the external pressure, allowing for a positive pressure test on the curtain wall. Through repeated pressurization tests, a more comprehensive wind pressure resistance test of the building curtain wall can be achieved. 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] Existing wind pressure resistance testing devices for building curtain walls may encounter gaps during installation due to varying curtain wall lengths. This can lead to movement of the curtain wall during wind pressure resistance testing, resulting in inaccurate test data.

[0021] In view of this, the present invention provides a wind pressure resistance testing device for building curtain walls. By cooperating with the placement plate, sealing plate and fixing bolts, the wind pressure resistance performance of the building curtain wall is tested. First, the building curtain wall is placed on top of the placement plate on the inner wall of the pressure chamber. Then, the personnel adjust the position of the sealing plate on the inner wall of the pressure chamber according to the length of the building curtain wall until it is pressed against the outer wall of the building curtain wall. Then, the sealing plate is fixed by fixing bolts. This allows for the installation and testing of building curtain walls of different lengths, and there is no need to worry about the building curtain wall moving during the testing process.

[0022] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0023] Example 1: By Figure 1-4 It is known that a wind pressure resistance performance testing device for building curtain walls includes a pressure box 1, a cover shell 2 is provided above the pressure box 1, a cover plate 3 is fixedly connected to the top of the cover shell 2, a plurality of distance sensors 4 are fixedly connected to the inner wall of the cover plate 3, a placement plate 5 is fixedly connected to the inner wall of the pressure box 1, a sealing plate 6 is inserted into the inner wall of the pressure box 1, the bottom of the sealing plate 6 is attached to the top of the placement plate 5, and a fixing bolt 7 is threadedly connected to the outer wall of the pressure box 1 near the sealing plate 6, the bottom of the fixing bolt 7 is pressed against the top of the sealing plate 6;

[0024] In the specific implementation process, it is worth noting that when testing the wind pressure resistance performance of the building curtain wall, the building curtain wall is first placed on top of the placement plate 5, and one side of the building curtain wall is pressed against the inner wall of the pressure box 1. Then, the personnel adjust the sealing plate 6 according to the length of the building curtain wall until it is moved to the other side of the building curtain wall. Then, the sealing plate 6 and the pressure box 1 are fixed by the fixing bolts 7. The wind pressure resistance performance of building curtain walls of different lengths can be tested by the distance sensor 4, the model of which is LK-G80.

[0025] Furthermore, a screw 8 is fixedly connected to the outer wall of the pressure box 1. The top of the screw 8 penetrates the top of the cover plate 3. The upper and lower sides of the outer wall of the screw 8 are respectively threaded with a first fixing member 9 and a second fixing member 10, and the first fixing member 9 and the second fixing member 10 are respectively located on the upper and lower sides of the cover plate 3.

[0026] In the specific implementation process, it is worth noting that before installing the building curtain wall, the staff first moves the cover shell 2 upward until it is in a position that is convenient for the staff to install the building curtain wall. Then, the staff can tighten the second fixing part 10 to fix the cover shell 2. After the staff has installed the building curtain wall, the staff moves the second fixing part 10 downward, and the cover shell 2 can move downward until the bottom of the cover shell 2 is in contact with the top of the building curtain wall and the sealing plate 6. Then, the staff tightens the first fixing part 9 to fix the cover shell 2. The pressure box 1, the inner wall of the placement plate 5 and the outer wall of the sealing plate 6 are all equipped with sealing gaskets to ensure that the pressure box 1 is in a sealed state when the wind pressure resistance performance test is carried out.

[0027] Example 2: From Figure 1-4 It can be seen that a vacuum pump 11 is provided on one side of the front of the pressure box 1. The input end of the vacuum pump 11 is connected to a solenoid valve 12. The end of the solenoid valve 12 away from the vacuum pump 11 is connected to the front of the pressure box 1. An air compressor 13 is provided on one side of the outside of the pressure box 1. The output end of the air compressor 13 is connected to a shut-off valve 14. The end of the shut-off valve 14 away from the air compressor 13 is connected to one side of the outer wall of the pressure box 1.

[0028] In the specific implementation process, it is worth noting that after the staff installs the building curtain wall and the cover shell 2, they first start the vacuum pump 11. The vacuum pump 11 extracts the air from the pressure box 1, and after continuous operation, it makes the pressure inside the pressure box 1 lower than the external pressure, which allows for negative pressure testing of the building curtain wall. After the negative pressure test is completed, the air compressor 13 is started. The start of the air compressor 13 makes the pressure inside the pressure box 1 greater than the external pressure, which allows for positive pressure testing of the building curtain wall. Through repeated pressurization tests, a more comprehensive assessment of the wind pressure resistance performance of the building curtain wall can be achieved. The test included a vacuum pump 11 (model 2XZ-2B) which simulates the inward suction force of air pressure, a solenoid valve 12 (model ZCF51) which controls the pumping speed of the vacuum pump 11 to the pressure box 1, and an air compressor 13 (model JPDJKYJ-01) which simulates the outward blowing force of air. The airflow can be quickly started and stopped by the shut-off valve 14. Both the solenoid valve 12 and the shut-off valve 14 are equipped with sealing rings on the side connected to the pressure box 1 to ensure that there is no leakage at the connection point.

[0029] Furthermore, a controller 17 is fixedly connected to one side of the outer wall of the cover 2;

[0030] In the specific implementation process, it is worth noting that the controller 17 is model LK-GD500. The distance sensor 4 transmits data to the controller 17. At this time, an external display can be connected so that the controller 17 can display the data. Based on the data values ​​of each distance sensor 4, the personnel can judge whether the deformation at each position meets the specified value, that is, whether the wind resistance of the curtain wall meets the requirements.

[0031] Furthermore, a pressure gauge 15 is installed on the front of the pressure box 1, and a pressure relief hole 16 is opened on the top of the cover plate 3.

[0032] In the specific implementation process, it is worth noting that when installing the cover shell 2, the bottom of the cover shell 2 should fit against the top of the building curtain wall and the sealing plate 6. Through the building curtain wall, the cover shell 2, and the pressure box 1, the pressure box 1 is kept in a sealed state. Before testing, the air compressor 13 can be started to pressurize the inside of the pressure box 1. Personnel should observe the changes in the pressure gauge 15 and observe for a period of time. If the value of the pressure gauge 15 is relatively stable and there is no continuous pressure drop, it indicates that the pressure box 1 is in a sealed state. Otherwise, there may be an air leak. At this time, personnel need to check and repair the leak. When conducting wind pressure resistance performance testing, the pressure relief hole 16 opened at the top of the cover plate 3 can connect the space pressure between the cover plate 3 and the building curtain wall and the sealing plate 6 with the external atmospheric pressure, keeping the air pressure consistent. This avoids the building curtain wall being squeezed due to excessive space pressure between the cover plate 3 and the building curtain wall and the sealing plate 6 during wind pressure resistance performance testing.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
