Description

Technical Field

[0001] This utility model relates to the field of wind pressure resistance testing technology for curtain walls, and in particular to a device for testing the wind pressure resistance performance of building curtain walls. Background Technology

[0002] A building curtain wall is a modern building exterior wall enclosure structure that does not bear the load of the main building structure. Instead, it is attached to the main structure by means of suspension or connection. A curtain wall system is usually composed of panels (such as glass, metal plates, stone, etc.) and a supporting structure behind them (such as aluminum alloy frames, steel structures, etc.). Therefore, wind resistance performance testing of building curtain walls is an important step in ensuring that the curtain wall structure can maintain its integrity and functionality under strong winds.

[0003] A search revealed that the document with announcement number "CN219590110U" mentions, "This utility model provides a curtain wall wind pressure resistance performance testing device, belonging to the field of testing equipment technology. It solves the problem of poor adaptability of existing wind resistance testing devices. This testing device includes a base, on which two mounting plates are fixed, with a gap between the two mounting plates. A pressure sensor is installed on the base platform located at the gap. Several pressure components are installed on the upper surfaces of the two mounting plates. This testing device also includes a fan blade located above the gap between the two mounting plates. The fan blade is driven by a servo motor, and the wind resistance performance of the curtain wall can be calculated by controlling the fan blade speed." It tests the wind resistance of the curtain wall by having the fan blade blow airflow of the corresponding wind force level directly onto the curtain wall. However, existing wind pressure resistance performance tests for building curtain walls typically use a fixed-direction wind generator, which cannot comprehensively evaluate the performance of the curtain wall under different wind directions and has limitations.

[0004] To address these issues, we have developed a device for testing the wind pressure resistance of building curtain walls. Utility Model Content

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

[0024] Please see Figure 1-4 As shown, a wind pressure resistance performance testing device for building curtain walls includes a main body 1 and a wind resistance testing mechanism 2, with the wind resistance testing mechanism 2 provided on the outer side of the main body 1.

[0025] The wind resistance testing mechanism 2 includes a fixing component 21 and an adjusting component 22. The fixing component 21 is installed at the top of the main body 1, and the adjusting component 22 is provided on the right side of the main body 1.

[0026] Furthermore, the fixing component 21 includes a support platform 211, a mounting bracket 212, a movable telescopic rod 213, a connecting platform 214, a fixing bracket 215, a locking groove 216, a locking bolt 217, and a movable clamping plate 218. The support platform 211 is welded to the top of the main body 1, and the mounting bracket 212 is welded to the right end of the support platform 211. The inner surface of the mounting bracket 212 is made of rubber. The curtain wall to be tested is placed on the mounting bracket 212, and the rubber material provides some protection for the curtain wall to avoid damage to the curtain wall due to collisions with the edges and corners during placement.

[0027] Furthermore, the top of the support platform 211 is connected to a movable telescopic rod 213, and a connecting platform 214 is welded to the top of the movable telescopic rod 213. A fixing frame 215 is fixedly connected to the right end of the connecting platform 214. The height of the fixing frame 215 can be adjusted by adjusting the movable telescopic rod 213, which is convenient for fixing curtain walls of different sizes.

[0028] Furthermore, a locking groove 216 is provided at the right end of the mounting bracket 212. A locking bolt 217 is threadedly connected to the inner side of the locking groove 216. A movable locking plate 218 is movably connected to the end of the locking bolt 217. By turning the locking bolt 217, the movable locking plate 218 can be moved within the mounting bracket 212 to lock and fix the curtain wall, ensuring stability during testing.

[0029] Furthermore, the adjustment component 22 includes a sliding mounting groove 221, a sliding table 222, a movable slide rail 223, a movable slider 224, a hydraulic lifting rod 225, a connecting frame 226, and a test fan 227. The sliding mounting grooves 221 are provided on both sides of the main body 1. The sliding table 222 is connected to the right side of the main body 1. The movable slide rail 223 is provided on the surface of the sliding table 222. The movable slider 224 is slidably connected to the inner side of the movable slide rail 223. By adjusting the position of the sliding table 222 on the right side of the main body 1, the distance between the test fan 227 and the curtain wall can be adjusted as needed. At the same time, the movable slider 224 slides in the movable slide rail 223, driving the test fan 227 to adjust its angle, which facilitates wind pressure resistance testing of the curtain wall from multiple angles and improves the test effect.

[0030] Furthermore, a hydraulic lifting rod 225 is installed at the top of the movable slider 224, a connecting frame 226 is welded to the top of the hydraulic lifting rod 225, and a test fan 227 is installed at the top of the connecting frame 226. The lifting and lowering of the connecting frame 226 is driven by the lifting and lowering of the hydraulic lifting rod 225, so that the test fan 227 can test different height positions of the curtain wall, increasing the comprehensiveness of the wind pressure resistance test angle of the curtain wall.

[0031] Example 2

[0032] Please see Figure 1 and Figure 4 As shown in the comparative embodiment 1, an environmental simulation component 3 is installed on the top of the test fan 227. The environmental simulation component 3 includes a storage box 31 and a barrier mesh 32. The storage box 31 is installed on the top of the test fan 227, and the barrier mesh 32 is installed on the inner side of the storage box 31. A certain amount of sand and gravel is added to the storage box 31 so that when the test fan 227 is operating, the sand and gravel will be shaken off from the storage box 31 by its own vibration and blown towards the curtain wall by the wind, simulating the situation of sand and gravel mixed in the wind in the actual environment, thereby improving the accuracy of the curtain wall test.

[0033] Working Principle: In use, firstly, install the device in the desired location, then place the curtain wall to be tested on the mounting bracket 212. Rubber material is used to protect the curtain wall from damage caused by impacts to its edges and corners during placement. Secondly, adjust the height of the fixed bracket 215 by adjusting the movable telescopic rod 213, facilitating the fixing of curtain walls of different sizes. Next, tighten the locking bolt 217 to move the movable clamp 218 within the mounting bracket 212, locking the curtain wall in place and ensuring stability during testing. Thirdly, adjust the position of the sliding table 222 on the right side of the device body 1 to adjust the distance between the test fan 227 and the curtain wall as needed. Simultaneously, the movable slider 224... The device slides within the movable slide rail 223, driving the test fan 227 to adjust its angle. This allows for wind pressure resistance testing of the curtain wall from multiple angles, improving the testing effectiveness. Fourthly, the hydraulic lifting rod 225 raises and lowers the connecting frame 226, enabling the test fan 227 to test different heights of the curtain wall, increasing the comprehensiveness of the wind pressure resistance test angles. Fifthly, a certain amount of sand and gravel is added to the storage box 31. When the test fan 227 operates, its vibrations shake the sand and gravel from the storage box 31, causing it to be blown towards the curtain wall by the wind, simulating the situation of sand and gravel mixed in the wind in a real environment, thus improving the accuracy of the curtain wall test. This completes the use of a building curtain wall wind pressure resistance performance testing device.

[0034] 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.
