Description

Technical Field

[0001] The invention relates to the technical field of building curtain wall detection, and in particular to a device for detecting displacement deformation performance of three-dimensional interlayer combination of building curtain walls. Background Art

[0002] Building curtain wall refers to the non-load-bearing outer wall enclosure of a building, which is usually composed of panels (glass, metal plates, stone plates, ceramic plates, etc.) and the supporting structure behind (aluminum beams and columns, steel structures, glass ribs, etc.). It has a certain displacement capacity relative to the main structure and does not share the effects on the main structure. It is a building's external protective structure or decorative structure. In addition to the requirements for airtightness, watertightness and wind pressure resistance, building curtain walls are also required to have interlayer deformation capacity, that is, through the action of static loading devices, the curtain wall specimens are subjected to low-cycle repeated motions to simulate the relative deformation caused by external forces such as earthquakes and wind, so as to detect the curtain wall's ability to withstand interlayer deformation.

[0003] The patent document with authorization announcement number CN 215811495 U discloses a device for detecting the deformation performance of interlayers of building curtain walls. When the curtain wall needs to be tested, the staff fixes the test plate (curtain wall specimen) in two fixed frames by adjusting bolts, and then pushes the top block through two cylinders, applies force to the test plate through the top block, observes the deformation process of the test plate, and then impacts the test plate through the impact assembly to achieve the purpose of testing the test plate. This effectively solves the problem that the various performance testing processes of existing curtain wall specimens are relatively scattered, the curtain wall specimens to be tested need to be transported, and the operation is relatively cumbersome.

[0004] However, the above-mentioned detection device can only test fixed positions on the curtain wall specimen during detection, resulting in the same test points for all curtain wall specimens, making it impossible to guarantee the accuracy of the detection data. In addition, the above-mentioned detection device is unable to adjust the impact force generated by the impact component according to the different curtain wall materials, resulting in a relatively single application scenario for the above-mentioned detection device.

A first electric push rod 25 is provided on the top of the nut 24. The first electric push rod 25 is vertically arranged upward.

The control end of the first electric push rod 25 is electrically connected to the controller 3.

[0035] When in use, the nut 24 can be driven to move radially along the mounting plate 21 by rotating the first screw rod 23 , thereby driving the first electric push rod 25 and the top block 26 thereon to move, so that the radial position of the top block 26 on the mounting plate 21 can be adjusted.

The upper surface of the translation plate 73 is in contact with the lower surface of the horizontal plate 82. When the translation plate 73 is driven to move by rotating the second screw rod 71, the translation plate 73 will slide along the horizontal plate 82, making the movement of the translation plate 73 more stable.

[0042] The two ends of the translation plate 73 are respectively provided with a third electric push rod 75 pointing vertically downward. The lower ends of the two third electric push rods 75 are fixedly connected to the top of the connecting frame 76. The two ends of the winding roller 78 are rotatably connected to the two ends of the connecting frame 76 through rolling bearings. One end of the winding roller 78 is connected to the output shaft of the second motor 710. The second motor 710 is fixedly installed on the outer surface of the connecting frame 76 through the motor mounting seat 9. When in use, the second motor 710 drives the winding roller 78 to rotate, and a rope 711 is wound on the winding roller 78.

[0043] A horizontal sliding rod 77 is fixedly provided on the outer side of the connecting frame 76, and the sliding rod 77 is perpendicular to the second screw rod 71. A sliding hole 717 is provided at one end of the sliding plate 79, and the sliding hole 717 is sleeved on the sliding rod 77, so that the sliding plate 79 is slidably connected with the sliding rod 77, and the sliding direction of the sliding plate 79 is parallel to the central axis of the winding roller 78. A sleeve hole 714 is provided at the other end of the sliding plate 79 in the vertical direction. One end of the rope 711 is fixedly connected to the winding roller 78, and the other end passes through the sleeve hole 714 downward. The impact block 715 is fixedly connected to the end of the rope 711 passing through the sleeve hole 714 and is located below the sliding plate 79.

[0044] In this embodiment, a second fixing plate 713 is fixedly provided below the sliding plate 79, and a fourth electric push rod 712 is provided on the side of the second fixing plate 713 and is horizontally facing the side where the impact block 715 is located. A limiting hole 716 is provided on the side of the impact block 715, and the piston rod of the fourth electric push rod 712 can be inserted into the limiting hole 716 when extended, so that the impact block 715 can be kept in the pulled-up position.

[0045] When in use, the impact block 715 can be adjusted in the horizontal direction by driving the second screw rod 71 to rotate through the first motor 72, and the impact block 715 can be adjusted in the longitudinal direction by manually sliding the sliding plate 79, so that the horizontal position of the impact block 715 can be adjusted at will. The impact force of the impact block 715 is adjusted by adjusting the height of the impact block 715 through the third electric push rod 75.

[0046] The fourth electric push rod 712 , the second motor 710 , the two third electric push rods 75 and the control end of the first motor 72 are all electrically connected to the controller 3 .

[0047] The use process of the detection device of this embodiment is as follows:

[0048] The user first places the curtain wall specimen to be tested on the two support plates 5, and controls the four second electric push rods 4 to retract through the controller 3, driving the two pressure plates 6 to descend so that the two pressure plates 6 are pressed on the curtain wall specimen, and then stops the retraction of the second electric push rods 4 to complete the fixation of the curtain wall specimen.

[0049] When performing a deformation test on a curtain wall specimen, first, according to the test requirements, rotate the first screw 23 and the worm 27 to adjust the position of the top block 26, and then control the first electric push rod 25 to extend upward through the controller 3, so that the top block 26 contacts the bottom of the curtain wall specimen, and continue to apply an upward force to the curtain wall specimen, thereby realizing a deformation test on the curtain wall specimen. After completing a test, the first electric push rod 25 is controlled to retract through the controller 3, so that the top block 26 falls off the curtain wall specimen, and then the top block 26 is adjusted to the next test position by rotating the first screw 23 and the worm 27 again, and the top block 26 is used to apply an upward force to the curtain wall specimen again, and the deformation test of the curtain wall specimen at the second position is performed. Repeating the above steps can perform deformation tests on multiple positions of the curtain wall specimen.

[0050] When performing an impact test on a curtain wall specimen, first adjust the horizontal position of the impact block 715 by rotating the second screw rod 71 and sliding the adjustment sliding plate 79, and then adjust the starting height of the impact block 715 by extending and retracting the third electric push rod 75 up and down, and adjust the impact block 715 to the position required for the test. Then, the controller 3 controls the second motor 710 to rotate, and the rope 711 is released from the winding roller 78. The rope 711 is released to a suitable length (enough for the impact block 715 to contact the curtain wall specimen after falling), and then the rotation of the second motor 710 is stopped. Then, the piston rod of the fourth electric push rod 712 is controlled to retract, and the piston rod of the fourth electric push rod 712 is disengaged from the limiting hole 716. At this time, the impact block 715 will perform free fall motion under the action of gravity, and finally impact the curtain wall specimen below, completing the first impact test on the curtain wall specimen. In the above steps, releasing the rope 711 in advance can better prevent the rope 711 from interfering with the falling of the impact block 715 , which is helpful for the user to judge and calculate the impact force generated by the impact block 715 .

[0051] After completing an impact test, the second motor 710 is controlled by the controller 3 to rotate in the opposite direction, driving the winding roller 78 to roll up the rope 711, and the impact block 715 will be pulled upward. When the impact block 715 reaches the height of the fourth electric push rod 712, the second motor 710 is stopped, and the position of the impact block 715 is manually adjusted so that the limiting hole 716 of the impact block 715 is aligned with the fourth electric push rod 712, and then the piston rod of the fourth electric push rod 712 is controlled to extend and insert into the limiting hole 716 to keep the impact block 715 at this height. After that, the second impact test can be carried out. When carrying out the second impact test, the starting height of the impact block 715 is adjusted by rotating the second screw rod 71 and sliding the adjustment sliding plate 79, and extending and retracting the third electric push rod 75 up and down, and the position of the impact block 715 is adjusted again. After the impact block 715 is adjusted to the second test position, the steps of the first impact test are repeated again to release the impact block 715, and the impact block 715 is free-falling and impacting the curtain wall specimen below, completing the second impact test.

[0052] Afterwards, the above steps are repeated to carry out impact tests on multiple positions of the curtain wall specimen.

[0053] After all tests are completed, the controller 3 controls the second electric push rod 4 to extend, so that the pressing plate 6 rises and separates from the curtain wall specimen, and then the curtain wall specimen that has completed the test is removed from the supporting plate 5.
