Description

Technical Field

[0001] This invention relates to the field of glass curtain wall testing technology, specifically to an edge load-bearing capacity testing device for glass curtain wall production. Background Technology

[0002] As the mainstream external envelope structure of modern buildings, the edge load-bearing capacity of glass curtain walls is directly related to the stability of curtain wall installation and the safety of use. Glass curtain walls must undergo strict edge load-bearing capacity testing before leaving the factory.

[0003] Currently, most commonly used testing equipment adopts a split structure. After the glass sample is placed, its position needs to be adjusted and clamped manually, making it difficult to achieve synchronous centering on both sides. This can easily lead to eccentric force on the sample, resulting in large deviations in the test data. Secondly, the support structure of traditional testing devices is mostly of the form of fixed spacing, which can easily lead to local suspension, stress concentration and other phenomena, and cannot truly simulate the actual installation stress conditions.

[0016] This edge load-bearing capacity detection device for glass curtain wall production uses a bottom support plate with two linked pressure plates that synchronously compress air cylinders. The air pressure linkage inflates the top limiting air cushion, achieving lateral flexible clamping and limiting of the upper edge of the glass. When the bottom support plate is pressed down, the two linked pressure plates simultaneously compress the air cylinders downward. The gas is delivered through the air guide straight pipe and air guide hose to the limiting air cushion under the pressure plate, causing the limiting air cushion to inflate and expand synchronously. This forms a uniform and flexible lateral clamping constraint on the upper edge of the glass from both sides, preventing the glass from tipping over or shifting during pressurization, and avoiding edge chipping or scratches caused by rigid clamping.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figures 1-9 The present invention provides a technical solution: an edge load-bearing capacity testing device for glass curtain wall production, comprising a frame base 1, a sample positioning mechanism 2 and a vertical loading mechanism 3.

[0021] The frame base 1 includes a base plate 101, a fixing frame 102, and a top plate 103. The fixing frame 102 has an overall portal frame structure, and the bottom end of the fixing frame 102 is welded and fixed to the four corners of the upper surface of the base plate 101. The top plate 103 is horizontally fixed to the top of the fixing frame 102 and is parallel to the base plate 101.

[0022] The sample positioning mechanism 2 includes two symmetrically distributed limiting platforms 201 on the upper surface of the base plate 101. The two limiting platforms 201 are symmetrically arranged along the length of the base plate 101, and the spacing is matched according to the width of commonly used glass curtain wall samples to ensure that the two ends of the sample can be stably placed on the support structure above the limiting platforms 201. The limiting platform 201 has a hollow cavity structure inside.

[0023] Two positioning seats 202 are fixedly connected to the upper surface of the limiting stage 201. The two positioning seats 202 are symmetrically distributed on the front and rear sides of the upper surface of the limiting stage 201. Rectangular through holes are opened on the opposite surfaces of the two positioning seats 202. Limiting top blocks 203 are slidably installed on the inner wall of the rectangular through holes. The outer dimensions of the limiting top blocks 203 match the rectangular through holes and can slide back and forth along the rectangular through holes. The two limiting top blocks 203 are used to press and limit the front and rear sides of the glass curtain wall sample to prevent the sample from shifting or moving back and forth during the loading process and to ensure that the sample is always in the center position of the test.

[0024] The limiting platform 201 has a rectangular cavity 204 inside. Two guide posts 205 are fixedly connected between the inner bottom wall and the inner top wall of the rectangular cavity 204. The guide posts 205 are made of round steel, and their upper and lower ends are welded and fixed to the inner wall of the rectangular cavity 204 to ensure verticality and no tilting. U-shaped connecting plates 206 are slidably fitted on the surface of the two guide posts 205. Guide holes are opened at both ends of the U-shaped connecting plates 206. The inner diameter of the guide holes is clearance-fitted with the outer diameter of the guide posts 205, allowing them to slide smoothly up and down along the guide posts 205.

[0025] A limiting groove 207 is formed on the middle surface of the limiting platform 201. The limiting groove 207 is formed vertically, and a bottom support plate 208 is slidably connected to the inner wall of the limiting groove 207. The side of the bottom support plate 208 is slidably engaged with the inner wall of the limiting groove 207, and can move up and down along the limiting groove 207. The end of the U-shaped connecting plate 206 away from the rectangular cavity 204 is fixedly connected to the surface of the bottom support plate 208. When the bottom support plate 208 moves up and down, it can drive the U-shaped connecting plate 206 to slide synchronously along the guide post 205.

[0026] A support spring 209 is fitted onto the surface of the guide post 205. The support spring 209 is a compression spring, with its top end fixedly connected to the lower surface of the U-shaped connecting plate 206 and its bottom end fixedly connected to the inner bottom wall of the rectangular cavity 204. The support spring 209 is always in a pre-compressed state, providing upward support force for the U-shaped connecting plate 206 and the bottom support plate 208. A strip-shaped guide hole 210 is provided on the inner wall of the rectangular cavity 204. The size of the strip-shaped guide hole 210 matches that of the U-shaped connecting plate 206, and the U-shaped connecting plate 206 is slidably connected to the inner wall of the strip-shaped guide hole 210.

[0027] A first hydraulic cylinder 211 is fixedly connected to the inner bottom wall of the rectangular cavity 204. The first hydraulic cylinder 211 is vertically fixed, and a first hydraulic rod 212 is slidably disposed inside the first hydraulic cylinder 211. One end of the first hydraulic rod 212 is fixedly connected to a first piston 213. The first piston 213 is slidably and sealingly connected to the inner wall of the first hydraulic cylinder 211 to prevent hydraulic oil leakage. The top end of the first hydraulic rod 212 extends to the outside of the first hydraulic cylinder 211 and is fixedly connected to the lower surface of the U-shaped connecting plate 206. The first hydraulic cylinder 211 is filled with hydraulic oil. When the U-shaped connecting plate 206 moves downward, it pushes the first hydraulic rod 212 and the first piston 213 downward, squeezing the hydraulic oil to generate hydraulic driving force and realize hydraulic transmission.

[0028] A vertical partition is fixedly connected to the inner wall of the positioning seat 202. A second hydraulic cylinder 214 is fixedly connected to the surface of the vertical partition. The second hydraulic cylinder 214 is horizontally fixed. A second hydraulic rod 215 is slidably arranged inside the second hydraulic cylinder 214. A second piston 216 is fixedly connected to one end of the second hydraulic rod 215. The second piston 216 is slidably and sealingly connected to the inner wall of the second hydraulic cylinder 214. The end of the second hydraulic rod 215 away from the second piston 216 extends to the outside of the second hydraulic cylinder 214 and is fixedly connected to the surface of the limiting top block 203. When hydraulic oil enters the second hydraulic cylinder 214, it pushes the second piston 216 and the second hydraulic rod 215 to extend, causing the limiting top block 203 to move forward, thereby clamping and limiting the sample.

[0029] Two limiting rods 217 are fixedly connected to the surface of the limiting top block 203. A limiting through hole matching the limiting rod 217 is provided on the surface of the vertical partition plate. The limiting rod 217 is slidably connected to the surface of the vertical partition plate through the limiting through hole. A return spring 218 is sleeved on the surface of the limiting rod 217. One end of the return spring 218 is fixedly connected to the surface of the limiting circular plate, and the other end is fixedly connected to the surface of the vertical partition plate. The return spring 218 provides a backward reset force to the limiting top block 203. When the hydraulic driving force disappears, the limiting top block 203 is pulled backward to reset, releasing the clamping of the sample. Anti-slip rubber pads 219 are fixedly connected to the surfaces of the two limiting top blocks 203 on their adjacent sides. The anti-slip rubber pads 219 are made of flexible, wear-resistant rubber material, making flexible contact with the sample surface to increase friction and improve the limiting effect, while avoiding rigid contact that could scratch the glass surface.

[0030] A liquid guide pipe 220 is fixedly embedded on the surface of the first hydraulic cylinder 211. The liquid guide pipe 220 is a high-pressure oil pipe, one end of which is connected to the lower cavity of the first hydraulic cylinder 211, and the other end is fixedly connected to the liquid inlet end of the second hydraulic cylinder 214.

[0031] The bottom support plate 208 has several mounting holes on its surface. Rubber support rollers 221 are rotatably mounted on the inner wall of the mounting holes. The rubber support rollers 221 are evenly arranged in a linear array on the surface of the bottom support plate 208. The rubber support rollers 221 are made of steel rollers with rubber coating to avoid scratching the sample edges and to ensure uniform force on the sample.

[0032] Both ends of the bottom support plate 208 are fixedly connected to a linkage pressure plate 305. The linkage pressure plate 305 extends horizontally outward, and a compressed air cylinder 306 is fixedly installed between its lower surface and the bottom plate 101. The compressed air cylinder 306 is arranged vertically, with its bottom end fixed to the upper surface of the bottom plate 101 and its top end connected to the lower surface of the linkage pressure plate 305. When the bottom support plate 208 moves downward, it drives the linkage pressure plate 305 to move downward synchronously, squeezing the compressed air cylinder 306 to generate compressed air. The output end of the compressed air cylinder 306 is fixedly connected to a straight air guide pipe 307. The straight air guide pipe 307 is arranged upward along the fixing frame 102, with its top end extending to below the top plate 103. The output end of the straight air guide pipe 307 is fixedly connected to a flexible air guide hose 308. The end of the flexible air guide hose 308 away from the straight air guide pipe 307 is fixedly connected to the air inlet end of the limiting air cushion 304, delivering compressed air to the limiting air cushion 304 to achieve air pressure linkage inflation.

[0033] The sample positioning mechanism 2 is pressed down by the bottom support plate 208, which drives the U-shaped connecting plate 206 to move down. This drives the first hydraulic rod 212 and the first piston 213 to move down, pressing hydraulic oil into the second hydraulic cylinder 214 through the guide pipe 220. This pushes the second hydraulic rod 215 and the limiting top block 203 to extend synchronously, adaptively and synchronously centering and clamping the front and rear sides of the glass curtain wall. At the same time, the linkage pressure plates 305 at both ends of the bottom support plate 208 synchronously compress the compressed air cylinder 306, using air pressure linkage to inflate the top limiting air cushion 304, realizing the lateral flexible clamping and limiting of the upper edge of the glass. This achieves double linkage positioning constraint from top to bottom, improving the stability of the test.

[0034] The vertical loading mechanism 3 includes two servo electric cylinders 301 fixedly installed on the upper surface of the top plate 103. The two servo electric cylinders 301 are symmetrically distributed on the left and right sides of the upper surface of the top plate 103. The telescopic ends of the two servo electric cylinders 301 extend to the bottom of the top plate 103 and are fixedly connected to a pressure plate 302. The servo electric cylinders 301 can drive the pressure plate 302 to move smoothly up and down, providing a stable vertical loading force.

[0035] The pressure plate 302 is located directly above the bottom support plate 208, ensuring that the loading force acts perpendicularly to the center of the sample. Two pairs of strip-shaped blocks 303 are fixedly connected to the lower surface of the pressure plate 302. These two pairs of blocks 303 are symmetrically distributed and are used to laterally constrain the upper edge of the sample. Each pair of blocks 303 has a limiting air cushion 304 fixedly embedded on their opposing surfaces. The limiting air cushion 304 is a flexible rubber air bladder that expands and deforms after inflation, flexibly fitting against the side of the sample to achieve flexible clamping constraint.

[0036] A mounting groove 309 is formed on the lower surface of the pressure plate 302. The mounting groove 309 is located at the center of the lower surface of the pressure plate 302. A pressure sensor 310 is fixedly embedded in the inner top wall of the mounting groove 309. The pressure sensor 310 is used to collect the loading pressure signal in real time. A pressure panel 311 is fixedly provided on the lower surface of the pressure sensor 310. The size of the pressure panel 311 matches the mounting groove 309. The pressure sensor 310 transmits the collected pressure signal to the control system to realize real-time display, recording and over-limit protection of the loading force.

[0037] A grating displacement sensor 312 is fixedly connected to the surface of the mounting bracket 102. The grating displacement sensor 312 is vertically fixed and serves as a displacement detection reference component. A grating reading head 313 is fixedly mounted on the surface of the strip-shaped stop 303. The position of the grating reading head 313 corresponds to that of the grating displacement sensor 312. The grating reading head 313 moves up and down synchronously with the strip-shaped stop 303 and the pressure plate 302. In conjunction with the grating displacement sensor 312, it collects the vertical displacement signal of the pressure mechanism in real time, reflecting the loading stroke and sample deformation displacement, and providing displacement data support for the test results. The pressure sensor 310, in conjunction with the grating displacement sensor 312, can acquire the pressure-displacement curve in real time, accurately reflecting the pressure-bearing performance of the glass curtain wall edge, and meeting the requirements of the testing standards.

[0038] The vertical loading mechanism 3 drives the pressure plate 302 downward through the servo electric cylinder 301, which in turn drives the pressure panel 311 to apply vertical pressure to the sample, simulating the actual stress conditions at the edge of the glass curtain wall. With the flexible constraint of the limiting air cushion 304, the loading process is stable and safe. At the same time, the pressure sensor 310 and the grating displacement sensor 312 realize the accurate acquisition of force and displacement signals, improving the accuracy and reliability of the test results.

[0039] Working principle: First, the glass curtain wall sample to be tested is placed horizontally on the bottom support plate 208 above the two limiting platforms 201. The left and right edges of the sample are placed on the rubber support rollers 221 respectively, and the sample is initially placed in the center of the testing area.

[0040] Then, the vertical loading mechanism 3 is activated, and the two servo electric cylinders 301 operate, driving the pressure plate 302 to move downward. As the servo electric cylinders 301 continue to apply downward pressure, the glass curtain wall sample is compressed, pushing the bottom support plate 208 to move downward along the limiting slide groove 207. During the downward movement of the U-shaped connecting plate 206, the first hydraulic rod 212 and the first piston 213 are pushed downward. The first piston 213 squeezes the hydraulic oil inside the first hydraulic cylinder 211. Under pressure, the hydraulic oil is quickly transported to the inside of the second hydraulic cylinder 214 through the guide pipe 220, pushing the second piston 216 and the second hydraulic rod 215 to extend forward. The second hydraulic rod 215 pushes the limiting top block 203 to move. The limiting top blocks 203 on the two positioning seats 202 move synchronously towards each other, and through the anti-slip rubber pad 219, the front and rear sides of the glass curtain wall sample are adaptively and synchronously centered and tightened, automatically achieving precise centered positioning of the sample.

[0041] As the bottom support plate 208 moves downward, the linkage pressure plates 305 at its left and right ends move downward simultaneously, squeezing the compressed air cylinder 306 below. The air inside the compressed air cylinder 306 is compressed to form high-pressure gas, which is quickly transported through the straight air guide pipe 307 and the air guide hose 308 to the limiting air cushion 304 on the strip-shaped stop 303 below the pressure plate 302. After being inflated, the limiting air cushion 304 gradually expands, forming a uniform and flexible lateral clamping constraint on the upper edge of the glass curtain wall sample from both sides.

[0042] The servo electric cylinder 301 continues to apply vertical pressure at a constant speed. The pressure panel 311 transmits the pressure evenly to the glass curtain wall sample. The pressure sensor 310 collects the loading pressure signal in real time. The grating reading head 313 moves synchronously with the pressure plate 302 and cooperates with the grating displacement sensor 312 to collect the vertical displacement signal in real time. The two sets of signals are transmitted synchronously to the control system. The system automatically records parameters such as yield load, ultimate load, and maximum displacement.
