[0002] A building curtain wall is a non-load-bearing exterior wall cladding system attached to the outside of the main building structure. It consists of panels and a supporting structure system and can have a certain displacement capacity relative to the main structure or a certain deformation capacity itself. It is not only the outer garment of a building, but also the core carrier for modern architecture to realize aesthetic expression, energy-saving performance and functional integration. It is widely used in high-rise buildings, commercial complexes, cultural venues and other landmark buildings. As a non-load-bearing cladding system attached to the outside of the main building structure, the building curtain wall is exposed to the complex outdoor environment for a long time. Wind load is the most important and frequent external force it bears.

Typically, the curtain wall is clamped and limited by a clamping mechanism, and then a high-pressure blower is used for testing. In actual application, moving the curtain wall onto the testing table requires multiple operators to work together, which is not only inefficient but also greatly increases the workload of the operators. Furthermore, the high-pressure blower is not easy to move as needed, resulting in poor performance. Utility Model Content

A clamping block 24 is slidably connected to the top surface of the clamping box 21. The outer surface of the lead screw body 23 has threads in opposite directions. One end of each of the two lead screw bodies 23 is fixedly connected to the output end of the two servo motors 22. The clamping block 24 has an L-shaped vertical cross-section. The bottom of the clamping block 24... The first set of inserts 25 is fixedly connected to the surface. The first set of inserts 25 is threadedly connected to the outer surface of the lead screw body 23. When the servo motor 22 in the clamping mechanism 2 is started, since one end of the lead screw body 23 is fixedly connected to the output end of the servo motor 22, and the outer surface of the lead screw body 23 has a thread layer with opposite directions, and the first set of inserts 25 fixed to the bottom surface of the clamping block 24 is threadedly connected to the outer surface of the lead screw body 23, when the servo motor 22 drives the lead screw body 23 to rotate, the two clamping blocks 24 will move relative to each other. Since the vertical cross section of the clamping block 24 is L-shaped, the curtain wall is clamped and fixed on the testing table 1.

[0025] The top surface of the testing table 1 is equipped with a pressure measuring mechanism 3. The pressure measuring mechanism 3 includes a storage cylinder 31 that is fixedly connected to the top surface of the testing table 1.

A pressure spring 34 is fixedly connected to the top surface of the support plate 33. The top of the pressure spring 34 is fixedly connected to a pressure measuring rod 35. The bottom surface of the pressure measuring rod 35 is slidably connected to the storage cylinder 31. When the curtain wall is deformed by wind pressure, it will press down on the pressure measuring rod 35. The bottom surface of the pressure measuring rod 35 is slidably connected to the storage cylinder 31. The pressure spring 34 fixedly connected to the bottom of the pressure measuring rod 35 is compressed. The bottom end of the pressure spring 34 is fixedly connected to the support plate 33. The pressure sensor 32 fixed to the bottom surface of the support plate 33 will detect the pressure change, thereby obtaining the stress data of the curtain wall under the action of wind and completing the wind resistance test.

[0026] A support column 4 is slidably connected through the top surface of the testing table 1. The support column 4 has a square horizontal cross-section. A first ball bearing is movably connected to the top surface of the support column 4 to reduce friction on the curtain wall and prevent damage.

The outer surface of the grounding rods 10 is fixedly connected to the sleeve end of the lifting electric push rod 6 via connecting rods. When the lifting electric push rod 6 extends and the top surface of the lifting plate 5 slides against the bottom surface of the testing table 1, the lifting plate 74 is raised to its maximum height. The top of the support column 4 is flush with the top surface of the lifting plate 74. At this time, the curtain wall is pushed directly from the surface of the lifting plate 74 to the top surface of the support column 4, moving the curtain wall above the testing table 1. When the support column 4 is raised to the extreme top position, the top of the first ball bearing on the support column 4 is flush with the top surface of the horizontal end of the clamping block 24. That is, when the clamping block 24 moves, the top surface of the horizontal end of the clamping block 24 is in contact with the curtain wall and is slidably connected to it to clamp the curtain wall. At the same time, when the pressure measuring rod 35 is not compressed, the top surface of the pressure measuring rod 35 is flush with the top surface of the horizontal end of the clamping block 24. That is, after the clamping block 24 clamps the curtain wall, the top surface of the pressure measuring rod 35 is in contact with the curtain wall and is not compressed.

[0027] A lifting mechanism 7 is provided on one side surface of the testing table 1. The lifting mechanism 7 includes a guide box 71 fixedly connected to one side surface of the testing table 1. A threaded rod 72 is provided in the inner cavity of the guide box 71. One end of the threaded rod 72 is fixedly connected to the output end of the forward and reverse reduction motor 73.

The lifting plate 74 is slidably connected to the opposite side surfaces of the two guide boxes 71. The forward and reverse reduction motor 73 drives the threaded rod 72 to rotate. Since the second set of inserts 75 fixed to both sides of the lifting plate 74 is threadedly connected to the outer surface of the threaded rod 72, and the lifting plate 74 is slidably connected to the opposite side surfaces of the two guide boxes 71, the rotation of the threaded rod 72 will cause the lifting plate 74 to move upward between the two guide boxes 71.

[0028] A top plate 8 is fixedly connected to the top surface of the testing table 1 via a connecting rod. A blower adjustment mechanism 9 is provided above the top plate 8. The blower adjustment mechanism 9 includes an I-shaped block 91 that is snapped and slidably connected to the top surface of the top plate 8. A high-pressure blower 92 is fixedly connected to the bottom surface of the I-shaped block 91. The high-pressure blower 92 is a known blower device that generates high-pressure air. A tensioning rod 93 is threaded through the top surface of the I-shaped block 91. An anti-slip soft layer is fixedly connected to the bottom surface of the tensioning rod 93. A rotating rod is fixedly connected to the outer surface of the top of the tensioning rod 93. The anti-slip soft layer is made of rubber to increase the friction between the rod and the top plate 8 and improve the stability of the I-shaped block 91.

[0029] It should be noted that, with the help of those skilled in the art, all electrical components in this case, such as servo motor 22, pressure sensor 32, lifting electric push rod 6, forward and reverse geared motor 73, high-pressure fan 92, etc., should be connected to their compatible power supplies via wires. Furthermore, a suitable controller, such as a PLC controller or microcontroller, should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the field. The following mainly introduces the working principle and process, without further explanation of the electrical control.

[0030] The working principle of the wind resistance testing equipment for building curtain walls in this embodiment is as follows: When in use, the operator first places the curtain wall to be tested on the lifting plate 74 of the lifting mechanism 7. The top surface of the lifting plate 74 is fitted with a second ball bearing, which can reduce the friction between the curtain wall and the lifting plate 74 and facilitate the movement of the curtain wall. Furthermore, the forward and reverse reduction motor 73 in the lifting mechanism 7 is activated. The forward and reverse reduction motor 73 drives the threaded rod 72 to rotate. The rotation of the threaded rod 72 will cause the lifting plate 74 to move upward between the two guide boxes 71 until the lifting plate 74 moves to the uppermost limit position. Furthermore, at this time, the lifting electric push rod 6 is activated, the lifting electric push rod 6 extends, driving the lifting plate 5 to rise, which in turn causes the support column 4 to rise. When the top surface of the lifting plate 5 is in contact with the bottom surface of the testing table 1, the lifting plate 74 is raised to its maximum height, and the top of the support column 4 is flush with the top surface of the lifting plate 74. Furthermore, by pushing the curtain wall on the surface of the lifting plate 74, the curtain wall is pushed directly from the surface of the lifting plate 74 to the top surface of the support column 4, thereby moving the curtain wall above the testing table 1. Furthermore, the servo motor 22 in the clamping mechanism 2 is activated. When the servo motor 22 drives the lead screw 23 to rotate, the two clamping blocks 24 will move relative to each other. Since the vertical cross section of the clamping block 24 is L-shaped, the curtain wall is clamped and fixed on the testing table 1. When the support column 4 is raised to the highest limit position, the top of the first ball on the support column 4 is flush with the top surface of the horizontal end of the clamping block 24. That is, when the clamping block 24 moves, its horizontal end top surface is attached to the curtain wall and slides to perform the clamping operation on the curtain wall. Furthermore, when the pressure measuring rod 35 is not compressed, the top surface of the pressure measuring rod 35 is flush with the top surface of the horizontal end of the clamping block 24. That is, after the clamping block 24 clamps the curtain wall, the top surface of the pressure measuring rod 35 is in contact with the curtain wall and is not subjected to pressure, which prepares for subsequent testing of the curtain wall's stress. Furthermore, the operator can push the I-shaped block 91 horizontally on the top plate 8 according to the shape and size of the curtain wall, which will drive the high-pressure fan 92 fixedly connected at the bottom to move. When the high-pressure fan 92 moves to the required position, the clamping rod 93 is rotated. The bottom surface of the clamping rod 93 is fixedly connected with an anti-slip soft layer, which can increase the friction between it and the top plate 8. Through the fixing action of the clamping rod 93, the I-shaped block 91 is fixed on the top plate 8, thereby fixing the high-pressure fan 92 in the required position. Furthermore, the high-pressure fan 92 is activated, blowing air onto the curtain wall to simulate the effect of wind on the curtain wall. At this time, the curtain wall is deformed by the wind pressure, which will press down on the pressure measuring rod 35. The bottom surface of the pressure measuring rod 35 is slidably connected to the storage cylinder 31. The pressure spring 34 fixedly connected to the bottom of the pressure measuring rod 35 is compressed. The bottom end of the pressure spring 34 is fixedly connected to the support plate 33. The pressure sensor 32 fixed to the bottom surface of the support plate 33 will detect the pressure change, thereby obtaining the force data of the curtain wall under the action of wind and completing the wind resistance test.
