Description

TECHNICAL FIELD

[0002] Currently, many high-rise buildings adopt curtain wall structures, including glass curtain walls, stone curtain walls and metal panel curtain walls. The building curtain wall refers to the non-load-bearing outer wall enclosure of a building, which is usually composed of panels (glass, metal plate, stone plate, ceramic plate, etc.) and the supporting structure (aluminum beam column, steel structure, glass rib, etc.) behind. Since most of the curtain walls are suspended outside the building, the impact resistance of the curtain wall needs to be detected before it is put into use to ensure its safety during use.

[0003] According to the search, the patent with the Chinese patent application number CN201420794270.X discloses a building curtain wall impact resistance performance testing device, which comprises a vertically arranged suspension frame body and a traction frame body.

[0054] Preferably, one side of the clamping plate 8 is attached with a non-slip pad 11; the friction between the outer wall of the curtain wall and the clamping plate 8 is reduced, so as to avoid the damage of the edge caused by the shaking of the curtain wall under the impact force during testing.

[0055] In order to facilitate the application of pressure impact force to the curtain wall; as shown in Figures 1-5 The outer walls of the two sides near the top end of the guide cylinder 5 are provided with moving grooves, and the inner walls of the two moving grooves are slidingly connected with the same pressing plate 25. The bottom surface of the pressing plate 25 is welded with an elastic element 22, the bottom end of the elastic element 22 is abutted with a gravity block 23, the top end of the gravity block 23 is tied with a connecting rope 27, the connecting rope 27 penetrates the inner wall of the pressing plate 25 and the top end of the guide cylinder 5 in sequence, and one end of the connecting rope 27 is tied with a ring plate 15.

[0058] Preferably, the outer wall of one side of the guide cylinder 5 facing the C-shaped plate 6 is provided with a plurality of positioning grooves 13 arranged in vertical array, and the inner wall of one of the positioning grooves 13 is inserted with a limiting plate 14; the outer wall of one side of the C-shaped plate 6 is bonded with a lifting reference ruler 16; the lifting reference ruler 16 is a reference ruler table of different levels of impact force calculated according to the lifting height of the gravity block 23 and the ejection speed of the elastic element 22, before people test the curtain wall, according to the different levels of impact force set on the lifting reference ruler 16, the limiting plate 14 is inserted into one of the positioning grooves 13 horizontally opposite to it, which is used as a switch for automatically releasing the gravity block 23 to impact, so as to accurately control different impact forces, specifically: when the moving block 28 passively follows the adjusting column 29 to move downward, when the opening end of the hook 19 abuts against the limiting plate 14, it will be abutted by the limiting plate 14 when continuously moving downward, thereby causing backward overturning, so that the annular plate 15 hung thereon is thrown out and separated, at this time, the gravity block 23 which is no longer pulled falls quickly under the ejection ability of the elastic element 22 and the action of its own weight to impact the detection point of the curtain wall.

[0059] Further, the bottom end of the guide cylinder 5 is provided with a number of impact limiting part, the number of impact limiting part includes the light curtain sensor 31 fixed on the inner wall of one side of the guide cylinder 5 by bolt, the hook plate 32 connected to the bottom end of the guide cylinder 5, the motor B 33 connected to the outer wall of one side of the guide cylinder 5 through the support plate, and the output end of the motor B 33 is connected with the top end of the hook plate 32 through the synchronous shaft, preferably, the support plate is C-shaped structure, which is convenient to control the rotation angle of the hook plate 32; the model of the light curtain sensor 31 is DLM40-4-J, the light curtain sensor 31 and the motor B 33 are in communication connection with the control module; preferably, the control module includes a timer, after the control module receives the signal of the light curtain sensor 31, the time difference of the falling of the gravity block 23 is calculated by the timer, and then the motor B 33 is controlled to start, so as to prevent the impact test from being unable to be completed. When the gravity block 23 falls from the guide cylinder 5, the detection signal of the light curtain sensor 31 is blocked at the moment when the gravity block 23 shoots out of the guide cylinder 5, and the signal is transmitted to the control module, the control module controls the hook plate 32 to rotate through the motor B 33, so that the hook plate 32 rotates 270 degrees, the connecting rope 27 above the gravity block 23 is hooked, and the connecting rope 27 is driven to deviate to one side, so that the gravity block 23 after impact is in a suspended state, thereby avoiding the secondary impact of the gravity block 23.

[0060] In the process of assembling the curtain wall, the curtain wall to be tested is placed in the placing groove 9, so that the four clamping plates 8 are clamped around the curtain wall under the driving of the buffer 17, then the adjusting pivot 7 is rotated to drive the threaded column 10 to rotate, and then the pressure block 12 is controlled to move downward in the through slot 24 until the bottom surface of the pressure block 12 is pressed against the top surface of the curtain wall, thereby firmly fixing the curtain wall.

[0061] Before detection, the reference lamp 30 is turned on, the light spot of the reference lamp 30 is irradiated on the surface to be tested of the curtain wall, the electric sliding rail 20 is started to drive the fixed seat 3 and the structure below the fixed seat 3 to move synchronously, thereby the straight detection range can be changed, then according to the horizontal distance between the point to be impacted and the bottom end of the guide cylinder 5, the top support 34 is started to drive the guide cylinder 5 to move forward and backward in the sliding groove, then the motor A 21 is started to drive the connecting plate 4 and the structure below the connecting plate 4 to move along the annular groove 35, thereby the circumferential directional detection point can be changed in a large range without changing.

[0062] When detecting, according to different levels of impact force provided on the lifting reference ruler 16, the limiting plate 14 is inserted into one of the positioning grooves 13 horizontally opposite to it, which is used as a switch for the automatic release of the gravity block 23. The ring-shaped plate 15 is hung in the hook 19, the motor C is started to drive the adjusting column 29 to rotate, thereby driving the moving block 28 to move downward, so that the hook 19 pulls the connecting rope 27 through the ring-shaped plate 15, the other end of the connecting rope 27 pulls the gravity block 23 in the guide cylinder 5 upward, so that the elastic member 22 is contracted and the pressure sensor 26 on the pressing plate 25 is attached to the inside of the top end of the guide cylinder 5. When the opening end of the hook 19 abuts against the limiting plate 14, it will be abutted by the limiting plate 14 when continuously moving downward, thereby causing the hook 19 to flip backward, so that the ring-shaped plate 15 hung thereon is thrown out and separated from the hook 19. At this time, the gravity block 23 is no longer pulled, and under the elastic ejection ability of the elastic member 22 and the action of its own weight, it quickly falls and hits the detection point of the curtain wall. The detection signal of the light curtain sensor 31 is blocked at the moment when the gravity block 23 is ejected from the guide cylinder 5, and the signal is transmitted to the control module. The control module controls the hook plate 32 to rotate 270 degrees through the motor B 33, so as to hook the connecting rope 27 above the gravity block 23 and drive it to deviate to one side, so that the gravity block 23 after hitting once is in a suspended state, thereby accurately controlling the number of impact detections.
