Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass curtain wall pressure testing technology, specifically to a tensile and compressive testing fixture for glass curtain walls. Background Technology
[0002] In the field of modern architecture, glass curtain walls are widely used due to their aesthetic appeal and good lighting. In practical applications, glass curtain walls need to withstand various external forces such as wind and earthquakes. If their tensile and compressive strength is not up to standard, serious safety hazards such as cracking and falling off may occur.
[0003] Currently, tensile and compressive testing fixtures have the following shortcomings: First, the contact area between the clamp and the glass curtain wall sample is small, resulting in uneven force distribution and large errors in the test results. Second, the testing fixtures lack versatility and are difficult to adapt to glass curtain walls of different specifications and installation methods. Third, there is a lack of effective clamping fixtures for holding glass curtain wall samples. Traditional fixtures have fixed clamping mechanisms or cumbersome adjustment methods, making it impossible to quickly and accurately clamp glass curtain walls of different sizes. This not only reduces testing efficiency but may also lead to inaccurate test results due to unstable clamping. Traditional clamping methods are mostly manual, which is inconvenient and difficult to guarantee accuracy, failing to meet the need for stable and reliable clamping of glass curtain walls of different widths, thus affecting the accuracy and reliability of the test.
[0004] Furthermore, during testing, the clamping and locking positions need to be determined based on the dimensions of the glass curtain wall sample to avoid requiring pressure testing values. Therefore, developing a tensile and compressive testing fixture for glass curtain walls that can solve the above problems is of significant practical importance. Utility Model Content
[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a tensile and compressive testing fixture for glass curtain walls, which can effectively solve the problem of pressure testing of glass curtain walls in the existing technology.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] This utility model provides a tensile and compressive strength testing fixture for glass curtain walls. A stabilizing frame is fixedly connected to the top of the testing platform, a guide rail is fixedly connected to the upper inner side of the stabilizing frame, a driving device is disposed outside the guide rail, a hydraulic cylinder is fixedly connected to the bottom of the driving device, and a testing device is fixedly connected to the end of the output shaft of the hydraulic cylinder. The fixture includes:
[0008] The clamping mechanism is attached to the top of the test bench at its lower part. The glass curtain wall body is clamped on the inner side of the clamping mechanism. The lower part of the clamping mechanism is fixed to the top surface of the guide block. The outer part of the guide block is slidably set in the guide groove, which is opened at the top of the test bench.
[0009] According to some embodiments of the present utility model, the clamping mechanism includes a clamping frame. A limiting groove is formed on the inner top surface of the clamping frame. A limiting block is clamped in the limiting groove. The lower end of the limiting block is integrally formed on the top of the clamping plate. The clamping plate is movably arranged in the clamping frame. A through hole is formed on the outside of the clamping frame. A stabilizing block is movably arranged in the through hole. The end of the stabilizing block is integrally formed on the side surface of the clamping plate.
[0010] According to some embodiments of the present utility model, a servo motor is fixedly connected to the side surface of the clamping frame. One end of a丝杆 is fixedly connected to the end of the output shaft of the servo motor. The丝杆 is externally screwed into the stabilizing block.
[0011] According to some embodiments of the present utility model, the through hole completely penetrates the side surface of the clamping frame. The thickness dimension of the through hole is equal to the height of the stabilizing block. There are two groups of through holes, and the two groups of through holes are axially symmetric about the center of the clamping frame.
[0012] According to some embodiments of the present utility model, the width of the guide groove is equal to the width of the guide block. A notch is formed at the bottom of the guide block. The end of the support shaft in the middle of the fixed roller is in the notch, and the roller is close to the guide groove.
[0013] According to some embodiments of the present utility model, the cross section of the clamping mechanism is in a "匚" - shaped structure, and the inner bottom surface of the clamping mechanism is closely attached to the lower part of the glass curtain wall body.
[0014] According to some embodiments of the present utility model, an operation panel is arranged on the side surface of the stabilizing frame. The operation panel is electrically connected to the driving device, the hydraulic cylinder and the testing device.
[0015] According to some embodiments of the present utility model, the cross section of the guide groove is in a "凸" - shaped structure. There are four groups of guide grooves, and the four groups of guide grooves are axially symmetric about the center of the test bench.
[0016] Beneficial effects
[0017] The technical solution provided by the present utility model has the following beneficial effects compared with the known prior art:
[0018] First, by starting the hydraulic cylinder, the testing device can be moved downward. The testing device performs a pressure test on the glass curtain wall body on the top of the test bench. Guide grooves are formed on the top of the test bench. The top surface of the guide block is fixedly connected to the bottom surface of the clamping mechanism. Thus, the position of the clamping mechanism can be adjusted on the top of the test bench. According to the glass curtain wall body of different specifications and sizes, the position of the clamping mechanism is adjusted to clamp it. By starting the servo motor, the丝杆 rotates outside the clamping frame. When the丝杆 rotates in the stabilizing block, the clamping plates automatically move closer to each other in the clamping frame. Therefore, the glass curtain wall body of different widths can be clamped by the clamping plates.
[0019] II. By fixing the middle support shaft of the roller in the notch of the guide block, when the clamping mechanism moves above the test bench, the roller reduces the friction for the guide block to move in the guide groove, so as to prevent the clamping mechanism from jamming when adjusting the position at the top of the test bench. The cross-section of the clamping mechanism is set in a "C" shape. When the clamping mechanism clamps the glass curtain wall body, the downward pressure applied by the test device to the top of the glass curtain wall body will cause it to bend and deform, and the two ends of the deformed glass curtain wall body will tilt up and abut against the inner top surface of the clamping mechanism. By electrically connecting the driving device, the hydraulic cylinder and the test device to the control panel on the side of the stabilizing frame, the three can be controlled. The pressure value applied by the test device to the glass curtain wall body can be read through the control panel. BRIEF DESCRIPTION OF THE DRAWINGS

SPECIFIC EMBODIMENTS
[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0028] The present invention will be further described below with reference to the embodiments.
[0029] See attached document Figure 1-5 A tensile and compressive strength testing fixture for glass curtain walls includes a stabilizing frame 2 fixedly connected to the top of a test platform 1, a guide rail 3 fixedly connected to the upper inner side of the stabilizing frame 2, a driving device 4 disposed outside the guide rail 3, a hydraulic cylinder 5 fixedly connected to the bottom of the driving device 4, and a testing device 6 fixedly connected to the end of the output shaft of the hydraulic cylinder 5. The fixture comprises:
[0030] The clamping mechanism 9 is attached to the top of the test platform 1. The inner side of the clamping mechanism 9 clamps the glass curtain wall body 10. The bottom of the clamping mechanism 9 is fixed to the top surface of the guide block 8. The outer side of the guide block 8 is slidably set in the guide groove 7, which is opened on the top of the test platform 1. The test device 6 can be moved downward by activating the hydraulic cylinder 5. The test device 6 performs a pressure test on the glass curtain wall body 10 on the top of the test platform 1. The guide groove 7 is opened on the top of the test platform 1, and the top surface of the guide block 8 is fixedly connected to the bottom surface of the clamping mechanism 9. Thus, the position of the clamping mechanism 9 can be adjusted on the top of the test platform 1. The position of the clamping mechanism 9 can be adjusted to clamp the glass curtain wall body 10 according to different specifications and sizes.
[0031] According to some embodiments of the present invention, the clamping mechanism 9 includes a clamping frame 91. A limiting groove 95 is formed on the inner top surface of the clamping frame 91. A limiting block 96 is engaged in the limiting groove 95. The lower end of the limiting block 96 is integrally formed on the top of the clamping plate 92. The clamping plate 92 is movably disposed in the clamping frame 91. An opening 94 is formed on the outside of the clamping frame 91. A stabilizing block 93 is movably disposed in the opening 94. The end of the stabilizing block 93 is integrally formed on the side of the clamping plate 92. By moving the outside of the stabilizing block 93 in the opening 94 and engaging the outside of the limiting block 96 in the limiting groove 95, the movement of the clamping plate 92 in the clamping frame 91 is limited and guided.
[0032] According to some embodiments of the present utility model, a servo motor 13 is fixedly connected to the side surface of the clamping frame 91. One end of a丝杆 12 is fixedly connected to the end of the output shaft of the servo motor 13. The丝杆 12 is externally screwed into the stabilizing block 93. By starting the servo motor 13, the丝杆 12 rotates outside the clamping frame 91. When the丝杆 12 rotates in the stabilizing block 93, the clamping plates 92 automatically move closer to each other in the clamping frame 91. Therefore, the glass curtain wall body 10 with different widths can be clamped by the clamping plates 92.
[0033] In the above technical solution, by starting the hydraulic cylinder 5, the testing device 6 can be moved downward. The testing device 6 performs a pressure test on the glass curtain wall body 10 on the top of the test bench 1. A guide groove 7 is opened on the top of the test bench 1. The top surface of the guide block 8 is fixedly connected to the bottom surface of the clamping mechanism 9. Thus, the position of the clamping mechanism 9 can be adjusted on the top of the test bench 1. According to the glass curtain wall body 10 with different specifications and dimensions, the position of the clamping mechanism 9 is adjusted to clamp it. By starting the servo motor 13, the丝杆 12 rotates outside the clamping frame 91. When the丝杆 12 rotates in the stabilizing block 93, the clamping plates 92 automatically move closer to each other in the clamping frame 91. Therefore, the glass curtain wall body 10 with different widths can be clamped by the clamping plates 92.
[0034] According to some embodiments of the present utility model, the through - hole 94 completely penetrates the side surface of the clamping frame 91. The thickness dimension of the through - hole 94 is equal to the height of the stabilizing block 93. The through - holes 94 are provided in two groups, and the two groups of through - holes 94 are axially symmetric about the center of the clamping frame 91. By setting the height of the stabilizing block 93 equal to the thickness of the through - hole 94, the phenomenon of shaking when the clamping plate 92 moves in the clamping frame 91 is prevented.
[0035] According to some embodiments of the present utility model, the width of the guide groove 7 is equal to the width of the guide block 8. A notch is opened at the bottom of the guide block 8. The end of the support shaft in the middle of the roller 11 is fixed in the notch. The roller 11 is closely attached to the guide groove 7. By fixing the middle support shaft of the roller 11 in the notch of the guide block 8, when the clamping mechanism 9 moves above the test bench 1, the roller 11 reduces the friction force when the guide block 8 moves in the guide groove 7, so as to prevent the clamping mechanism 9 from getting stuck when adjusting the position on the top of the test bench 1.
[0036] According to some embodiments of the present utility model, the cross - section of the clamping mechanism 9 is in a "C" - shaped structure. The inner bottom surface of the clamping mechanism 9 is closely attached to the lower part of the glass curtain wall body 10. By setting the cross - section of the clamping mechanism 9 in a "C" - shaped structure, when the clamping mechanism 9 clamps the glass curtain wall body 10, the downward pressure applied by the testing device 6 to the top of the glass curtain wall body 10 will cause it to bend and deform, and the two ends of the deformed glass curtain wall body 10 will翘起 and abut against the inner top surface of the clamping mechanism 9.
[0037] According to some embodiments of the present utility model, a control panel is provided on the side of the stabilizing frame 2. The control panel is electrically connected to the driving device 4, the hydraulic cylinder 5, and the testing device 6. By electrically connecting the driving device 4, the hydraulic cylinder 5, and the testing device 6 to the control panel on the side of the stabilizing frame 2, the three can be controlled, and the pressure value applied by the testing device 6 to the glass curtain wall body 10 can be read through the control panel.
[0038] In the above technical solution, by fixing the middle support shaft of the roller 11 in the notch of the guide block 8, when the clamping mechanism 9 moves above the test bench 1, the roller 11 reduces the friction force for the guide block 8 to move in the guide groove 7, so as to prevent the clamping mechanism 9 from getting stuck when adjusting its position on the top of the test bench 1. The cross-section of the clamping mechanism 9 is set in a "C" shape. When the clamping mechanism 9 clamps the glass curtain wall body 10, the downward pressure applied by the testing device 6 to the top of the glass curtain wall body 10 will cause it to bend and deform, and the two ends of the deformed glass curtain wall body 10 will tilt up and abut against the inner top surface of the clamping mechanism 9. By electrically connecting the driving device 4, the hydraulic cylinder 5, and the testing device 6 to the control panel on the side of the stabilizing frame 2, the three can be controlled, and the pressure value applied by the testing device 6 to the glass curtain wall body 10 can be read through the control panel.
[0039] Working principle: By starting the hydraulic cylinder 5, the testing device 6 can be moved downward. The testing device 6 conducts a pressure test on the glass curtain wall body 10 on the top of the test bench 1. A guide groove 7 is opened on the top of the test bench 1, and the top surface of the guide block 8 is fixedly connected to the bottom surface of the clamping mechanism 9, so that the position of the clamping mechanism 9 can be adjusted on the top of the test bench 1. According to the glass curtain wall body 10 of different specifications and sizes, the position of the clamping mechanism 9 is adjusted to clamp it. By starting the servo motor 13, the丝杆12 rotates outside the clamping frame 91. When the丝杆12 rotates in the stabilizing block 93, the clamping plates 92 automatically move closer to each other in the clamping frame 91. Therefore, the glass curtain wall body 10 of different widths can be clamped by the clamping plates 92. The cross-section of the clamping mechanism 9 is set in a "C" shape. When the clamping mechanism 9 clamps the glass curtain wall body 10, the downward pressure applied by the testing device 6 to the top of the glass curtain wall body 10 will cause it to bend and deform, and the two ends of the deformed glass curtain wall body 10 will tilt up and abut against the inner top surface of the clamping mechanism 9.
[0040] The above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit it; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the various embodiments of the present utility model.
