Description

Technical Field

[0001] This utility model relates to the field of curtain wall static pressure box technology, specifically a curtain wall static pressure box for testing the physical performance of building curtain walls. Background Technology

[0002] A curtain wall static pressure chamber is a testing device used in the physical performance testing of building curtain walls. It is used to simulate the stress state of the curtain wall under static loads such as wind pressure. Its main function is to apply controlled static pressure loads to help test the pressure resistance, sealing performance, and structural stability of the curtain wall system.

[0003] In the existing technology, when the physical performance of the curtain wall is tested in the static pressure box of the curtain wall, the airtightness of the box is defective, which easily leads to air leakage. To overcome the above shortcomings, a prior art Chinese patent (publication number CN216524581U) discloses a curtain wall static pressure test chamber for testing the physical performance of building curtain walls. The chamber includes a curtain wall body installed on a wall and a base. Two lifting mechanisms are provided at the bottom of the base. An electric push rod is fixedly installed on the base. A frame is slidably connected to the top of the base. The telescopic end of the electric push rod is fixedly connected to the side wall of the frame. A box body is fixedly installed on the frame. The box body has an annular groove, two mounting grooves, and two sliding grooves. A sealing mechanism is provided in the annular groove. A snap-fit ​​mechanism is provided in each of the two mounting grooves, extending into the sealing mechanism and abutting against its inner wall. A compression mechanism is provided in each of the two sliding grooves. The structure is reasonably designed, allowing for easy removal and replacement of the sealing ring on the box body, ensuring the normal operation of the testing work. It also achieves a sealed connection between the sealing ring and the box body, ensuring the airtightness of the box body.

[0004] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation. For example, when testing the sealing of the curtain wall static pressure box, if different locations of the curtain wall need to be tested, the upper part of the curtain wall with a higher height has a higher requirement for the height of the curtain wall static pressure box. When conducting sealing tests, it is necessary to raise the curtain wall static pressure box, which is cumbersome and can easily affect the efficiency of the specific test, making it unfavorable for users. Summary of the Invention

[0005] The purpose of this utility model is to provide a curtain wall static pressure box for testing the physical performance of building curtain walls, so as to solve the problem mentioned in the background art that when testing the sealing of the curtain wall static pressure box, if it is necessary to test the curtain wall at different locations, the overall adjustment is cumbersome, which can easily affect the efficiency of the specific test and is not conducive to the use of the user.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a static pressure test chamber for testing the physical performance of building curtain walls, comprising a base and a slide rail mounted on the upper end of the base, a movable platform sleeved on the surface of the slide rail, and a detector and a chamber mounted on the upper end of the movable platform, with the chamber and detector connected by a pipe; a hydraulic rod is installed through the outer side of the base, and a support plate is fixedly installed at the lower end of the hydraulic rod, the hydraulic rod drives the support plate to descend and lift the base and the upper chamber, enabling rapid testing by adjusting the position of the chamber; the left side of the chamber is open, and a sealing strip is provided at the left end of the chamber; a bracket is provided on the outer side of the chamber, and an auxiliary replacement mechanism is provided inside the bracket.

[0007] Furthermore, the bottom of the support plate is provided with an anti-slip pad, and the support plate is located at the lower center of the base.

[0008] Furthermore, the auxiliary replacement mechanism is provided with a mounting block, and the left end of the mounting block is fixedly installed on the right side of the sealing strip. The right side of the mounting block is embedded inside the housing, and two sealing strips are provided correspondingly on the top and bottom.

[0009] Furthermore, a pull rod is installed through the middle of the bracket, and an adjustment plate is fixedly installed at the lower end of the pull rod, and a locking block is fixedly installed at the lower end of the adjustment plate.

[0010] Furthermore, the lower end of the locking block forms a locking structure with the mounting block, and a pressure spring is provided between the adjusting plate and the bracket.

[0011] Furthermore, the mobile platform is equipped with an auxiliary airbag inside, and an auxiliary sealing mechanism is provided on the outside of the auxiliary airbag.

[0012] Furthermore, the auxiliary sealing mechanism is provided with a contact plate, and the middle end of the contact plate is installed through the interior of the mobile platform. The contact plate is connected to the auxiliary airbag, and the auxiliary airbag is elastically set. The auxiliary airbag and the sealing strip are connected through a connecting pipe, and a connecting knob is provided at the middle end of the connecting pipe. The lower end of the auxiliary airbag is connected to the air inlet of a one-way valve.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. The static pressure chamber for testing the physical performance of building curtain walls of this utility model, when in use, uses an electric telescopic rod at the upper end of the base. When the electric telescopic rod is activated, it can push the moving platform to slide along the slide rail to adjust the position. At this time, after the chamber is aligned with the building curtain wall and closed, the air inside the chamber is pressurized by the detector, thereby realizing the physical performance test. Furthermore, by activating the hydraulic rod, the hydraulic rod can push the support plate, thereby raising the position of the base and the chamber through the reverse action, thus realizing the convenient adjustment of the test position without the need for a manual raising device, achieving the function of convenient adjustment of different test heights; 2. The static pressure test chamber for testing the physical performance of building curtain walls of this utility model has a sealing strip on the outside of the chamber. When the chamber is closed for testing, the sealing strip can effectively seal the chamber, thus achieving a more accurate sealing test. 3. The static pressure test chamber for testing the physical performance of building curtain walls of this utility model allows the sealing strip to be embedded inside the chamber through the installation block during installation. After the installation block is embedded inside, the locking block engages with the installation block. The pull rod is pulled along the support to lift the adjustment plate. The adjustment plate drives the locking block to move upward and compress the pressure spring, thereby enabling convenient disassembly and installation of the sealing strip. The operation is simple and convenient.

[0014] 4. The static pressure chamber for testing the physical performance of building curtain walls of this utility model, when in use, as the chamber body is attached to the surface of the curtain wall, the contact plate at the end of the moving platform contacts the curtain wall. As the chamber body moves, the contact plate squeezes the auxiliary airbag under the reaction force. The auxiliary airbag is squeezed and the air inside is forced into the sealing strip through the connecting pipe, thereby applying pressure and further improving the sealing effect of the sealing strip, ensuring the accuracy of subsequent tests.

[0022] 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.

[0023] Example 1: As Figures 1-3 The technical solution shown, a static pressure chamber for testing the physical performance of building curtain walls, discloses the following to address the inconvenience of testing curtain wall performance at different locations: a base 1 and a slide rail 4 mounted on the upper end of the base 1. A moving platform 6 is fitted onto the surface of the slide rail 4, and a detector 7 and a chamber 8 are mounted on the upper end of the moving platform 6. The chamber 8 and the detector 7 are connected by a pipe. The detector 7 contains components for evaluating four core performance aspects of the building curtain wall, including a gas flow measurement device for detecting airtightness. The gas flow measurement device is used to detect airtightness at the location covered by the chamber 8, thereby collecting airtightness data of the curtain wall. It also includes a pressure control device and a pressure sensor for detecting pressure. The pressure controller and pressure sensor apply pressure to the curtain wall during pressure testing. The pressure is judged to collect data and test the compressive strength of the curtain wall, so that the staff can judge whether the compressive strength of the curtain wall is qualified. The detector 7 is also equipped with an air supply device to provide air power. Through the connected pipe, air is supplied to the inside of the box 8 to achieve detection. The continuous air supply applies pressure to achieve the effect of convenient air supply measurement (the internal mechanism of the detector 7 is made using existing detection devices). A hydraulic rod 2 is installed through the outside of the base 1, and a support plate 3 is fixedly installed at the lower end of the hydraulic rod 2. The hydraulic rod 2 drives the support plate 3 to descend and lift the base 1 and the upper box 8, so that the position adjustment of the box 8 can achieve rapid detection. The left side of the box 8 is open. The bottom of the support plate 3 is equipped with an anti-slip pad, and the support plate 3 is located at the lower center of the base 1.

[0024] In use, the electric telescopic rod 5 at the top of the base 1 pushes the moving platform 6 to slide along the slide rail 4 to adjust its position. At this time, the box 8 is aligned with the building curtain wall and closed. After the box 8 is in contact with the curtain wall position that needs to be sealed, the detector 7 is activated to pressurize the air inside the box 8. As the pressure inside the box 8 increases, physical performance testing can be achieved. The physical performance of the curtain wall is judged based on the final result. When testing a higher position of the curtain wall, the hydraulic rod 2 is activated. The activation of the hydraulic rod 2 pushes the bottom support plate 3. As the hydraulic rod 2 pushes the support plate 3 to descend, the anti-slip pad at the bottom of the support plate 3 presses down stably on the ground. This reverse action raises the position of the base 1 and the box 8, thus enabling convenient adjustment of the testing position without the need for manual shims, achieving convenient adjustment of different testing heights.

[0025] Example 2: Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 The technical solution shown, based on Embodiment 1, discloses the following to address the inconvenience of operation and replacement: a sealing strip 9 is provided at the left end of the housing 8; a bracket 11 is provided on the outside of the housing 8; an auxiliary replacement mechanism is provided inside the bracket 11; the auxiliary replacement mechanism includes a mounting block 10; the left end of the mounting block 10 is fixedly installed on the right side of the sealing strip 9; and the right side of the mounting block 10 is embedded inside the housing 8. Two sealing strips 9 are provided vertically. A pull rod 12 is installed through the middle of the bracket 11; an adjusting plate 13 is fixedly installed at the lower end of the pull rod 12; and a locking block 14 is fixedly installed at the lower end of the adjusting plate 13. The lower end of the locking block 14 and the mounting block 10 form a locking structure. The adjusting plate 13 and the bracket... A pressure spring 15 is installed between the 11 brackets. A sealing strip 9 is installed on the outside of the housing 8. The sealing strip 9 can effectively seal the housing 8 when it is closed for detection, achieving a more accurate sealing detection effect. At the same time, when the sealing strip 9 is installed, it is embedded into the housing 8 through the mounting block 10. After the mounting block 10 is embedded, it is engaged by the locking block 14. Under the pressure of the pressure spring 15, the adjusting plate 13 and the locking block 14 are pressed down. If it is necessary to remove the mounting block 10 and the sealing strip 9, the pull rod 12 is pulled. The pull rod 12 is pulled along the bracket 11 to lift the adjusting plate 13. The adjusting plate 13 drives the locking block 14 to move upward and squeeze the pressure spring 15. This allows for easy removal and installation of the sealing strip 9. The operation is simple and convenient.

[0026] Example 3: Figure 1 , Figure 2 , Figure 5 and Figure 6The technical solution shown, based on Embodiment 2, discloses the following to address the problem of insufficient sealing strength: an auxiliary airbag 16 is provided inside the mobile platform 6, and an auxiliary sealing mechanism is provided on the outside of the auxiliary airbag 16. The auxiliary sealing mechanism is provided with a contact plate 17, and the middle end of the contact plate 17 is installed through the inside of the mobile platform 6. The contact plate 17 is connected to the auxiliary airbag 16, and the auxiliary airbag 16 is elastically configured. The auxiliary airbag 16 is connected to the sealing strip 9 through a connecting pipe 18, and a connecting knob 19 is provided at the middle end of the connecting pipe 18. The lower end of the auxiliary airbag 16 is connected to the air inlet of a one-way valve.

[0027] As the housing 8 adheres to the curtain wall surface, the contact plate 17 at the end of the moving platform 6 contacts the curtain wall. With the movement of the housing 8, the contact plate 17, under reaction force, compresses the auxiliary airbag 16. The compressed auxiliary airbag 16 forces the internal air through the connecting pipe 18 into the sealing strip 9, thereby applying pressure and further improving the sealing effect of the sealing strip 9, ensuring the accuracy of subsequent testing. Simultaneously, when disassembling the sealing strip 9, the connecting pipe 18 can be disconnected via the connecting knob 19; when installing the sealing strip 9, the connecting pipe 18 can be reconnected via the connecting knob 19. Furthermore, the auxiliary airbag 16 expands due to its own elasticity and draws air through the one-way air inlet at the lower end, allowing for reuse and further improving the performance of the curtain wall static pressure test chamber. The overall performance and parameters of the equipment are as follows: Static pressure difference of the pressure chamber: ±10... kPa: By adjusting the static pressure difference of the pressure box, the compressive strength of the curtain wall can be tested; Dynamic wind pressure fluctuation: 2500Pa: With the air supply device set, air is continuously supplied to the inside of the box 8 to achieve the pressurization effect; Air flow range: 0~1000m³ / h: As the air supply device flows, data on the air flow range is collected to facilitate subsequent specific judgment and testing of the physical performance of the curtain wall; Water spray rate: 0~4L / (m²·min): Adjusting the water spray rate allows for the judgment of the curtain wall performance under different rainfall amounts, simulating the effects of different weather conditions, making the test more comprehensive.

[0028] Furthermore, the overall equipment complies with the following national standards for reference: GB / T 15227-2007 Test Methods for Air Tightness, Water Tightness and Wind Pressure Resistance of Building Curtain Walls; GB / T 18250-2000 Test Methods for In-Plane Deformation Performance of Building Curtain Walls; GB / T 21086-2007 Building Curtain Walls.

[0029] 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.
