[0018] 1. The present invention can aggravate the stress concentration phenomenon by applying extrusion force toward the center at the four corners of the curtain wall body, especially at material defects, so that the detection of microcracks becomes more sensitive and potential weak links can be discovered early;

[0019] Under multi-directional forces, the overall stability of the curtain wall body and the reliability of the connection nodes are tested, which can effectively verify the rationality of the curtain wall design and the construction quality, and ensure the integrity of the structure under extreme load conditions. The test results can reveal the performance differences of different materials and designs under complex stress states, and provide a basis for selecting more suitable curtain wall materials, optimizing structural design, and enhancing connection methods.

[0020] Simulating the extreme load conditions that may be encountered in reality can more accurately predict the performance of the curtain wall throughout its life cycle, including durability, deformation resistance and damage accumulation.

[0021] 2. The present invention can apply uneven pressures of different distributions on the curtain wall body by adjusting the positions of the protrusions.

[0022] Moreover, the stress concentration phenomenon caused by uneven normal stress can effectively detect the local strength and stability of the curtain wall body under extreme or abnormal stress conditions, helping to identify and prevent potential local damage risks;

[0023] When bending or deflecting under stress, the elastoplastic behavior, ultimate bearing capacity and deformation recovery performance of the curtain wall material can be deeply evaluated to ensure the reliability and durability of the curtain wall in normal use and under extreme conditions.

[0024] 3. In the present invention, by adjusting the position of the stress arc groove, the direction and distribution of the pressure applied to the four corners of the curtain wall body are dynamically changed, so that the complex stress state of different angles and distributions can be simulated. The adjustable design of the stress arc groove allows the tester to accurately control the force application process and gradually increase or change the pressure, so as to analyze the response of the curtain wall at different pressure stages in detail and obtain detailed data on the curtain wall performance;

[0025] Since the forces converge toward the center of the curtain wall, the central area is subject to higher compressive stress. This test is particularly helpful in evaluating the bearing capacity and stability of the core area of ​​the curtain wall, and detecting whether the curtain wall will collapse or be damaged in the center under extreme loads.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] refer to Figures 1 to 17 The compression test device for a wall-mounted metal composite reinforced plate light decorative curtain wall shown in the figure comprises a test box 1, a support frame 2 is arranged at the bottom of the test box 1, a pressure mechanism 3 is arranged at the middle of the lower end of the test box 1, a support mechanism 4 is arranged on the side wall of the support frame 2, a curtain wall body 5 is clamped inside the support mechanism 4, four angle mechanisms 6 for clamping the four corners of the curtain wall body 5 are arranged inside the support mechanism 4, and a compressive stress testing mechanism 7 for pushing the angle mechanism 6 to apply extrusion force to the curtain wall body 5 is arranged at the bottom of the support mechanism 4;

[0046] It is worth noting that the curtain wall body 5 that needs to be subjected to the compression test is placed in the support mechanism 4, and the support mechanism 4 fixes and clamps the curtain wall body 5. The curtain wall body 5 set can be a wall-mounted metal composite reinforced plate light decorative curtain wall or other metal or wooden decorative curtain walls. When the curtain wall body 5 is subjected to the compression test, the pressure mechanism 3 moves downward to squeeze the curtain wall body 5, and the detector 711 set in the compressive stress testing mechanism 7 can detect the stress condition of the curtain wall body 5 after receiving the downward pressure, and the pressure can also be adjusted by the pressure mechanism 3. The point where pressure is applied changes the stress condition of the curtain wall body 5, and the compressive state of the curtain wall body 5 under stress conditions at different positions is tested. The force applied by the pressure-applying mechanism 3 is unevenly applied to the metal plate, causing one side of the curtain wall body 5 to be compressed while the other side is relatively free of stress. This uneven pressure application causes the curtain wall body 5 to bend toward the stressed side, forming a deflection or bending moment, generating a larger compressive stress on the stressed side and a tensile stress on the other side. Due to the uneven stress distribution of the curtain wall body 5, stress concentration will occur near the edge and stress point of the curtain wall body 5;

[0047] Among them, by applying uneven pressure at different positions by the pressure-applying mechanism 3, the mechanical properties of the curtain wall body 5 material, whether it is a metal composite reinforced plate or other materials, under various possible stress states, including strength, stiffness and stability, can be comprehensively examined, which should help identify potential weaknesses in the curtain wall body design or materials, such as structural discontinuity, material defects or processing flaws, and prevent premature damage or fracture caused by stress concentration in actual applications;

[0048] Testing under simulated extreme or non-uniform loading conditions helps verify that the curtain wall structure meets safety standards and ensures that it can maintain sufficient stability and durability when faced with actual external impacts such as strong winds, earthquakes or other external forces.

[0049] When the pressure mechanism 3 moves downward to apply pressure to the curtain wall body 5, the pressure stress testing mechanism 7 moves upward to squeeze the curtain wall body 5. The pressure stress testing mechanism 7 and the pressure mechanism 3 can simultaneously apply pressure to the curtain wall body 5 to form a stress state similar to extrusion. The upward force at the bottom center of the curtain wall body 5 and the downward force at the top periphery act together to compress the curtain wall body 5 in the vertical direction, and at the same time generate a closed stress state in the horizontal direction. The central area of ​​the curtain wall body 5 will be subjected to compressive stress, while the periphery, especially the top periphery, will be subjected to a complex stress state. This pressurization method causes the curtain wall body 5 to present a complex deformation mode, including compression and local distortion or warping.

[0050] Among them, by simultaneously applying downward pressure on the periphery of the top of the curtain wall body 5 and applying force upward at the center of the bottom, it is possible to more closely simulate the complex load conditions that may be encountered in actual applications, such as the scene where the top of the building is subjected to wind pressure and the bottom is subjected to support reaction force, thereby improving the realistic simulation and effectiveness of the test;

[0051] This comprehensive stress state can comprehensively evaluate the compression, shear and torsion resistance of the curtain wall, help determine whether the curtain wall can maintain the overall stability and rigidity of the structure under complex stress states, and prevent accidents caused by structural instability.

[0052] Under the closed stress state, the curtain wall's connectors, sealing strips and frame components will be subjected to great closed stress. The strength and sealing issues of key parts are tested to ensure the integrity of the curtain wall system.

[0053] The set compressive stress testing mechanism 7 can also be moved upwards alone to contact the curtain wall body 5. Since the compressive stress testing mechanism 7 is located at the center of the curtain wall body 5, the compressive stress testing mechanism 7 contacts the curtain wall body 5 to apply an upward pressure to the curtain wall body 5, so that the force on the curtain wall body 5 is evenly distributed on the curtain wall body 5, resulting in similar elastic or plastic deformation in the central area and the peripheral area of ​​the curtain wall body 5.

[0054] When the compressive stress testing mechanism 7 simultaneously pushes the angle mechanism 6 to apply force from the four corners of the curtain wall body 5 in the direction of extrusion pressure toward the center of the curtain wall body 5, the force exerted on each corner of the curtain wall body 5 converges toward the center, and a compressive stress field from the surroundings to the center is generated inside the curtain wall body 5. The central area will be subjected to higher compressive stress. The curtain wall body 5 is compressed in four directions at the same time. When the applied pressure exceeds the elastic limit of the curtain wall body 5 material, plastic deformation will occur. At material defects such as microcracks, cracks will be initiated and expanded. The curtain wall body 5 is compressed inward as a whole. When the angle mechanism 6 constrains the four corners of the curtain wall body 5 to apply force, it causes local bending or distortion of the curtain wall body 5.

[0055] Among them, by applying a squeezing force toward the center at the four corners of the curtain wall body 5, the stress concentration phenomenon can be aggravated, especially at material defects, such as micro-cracks, the detection becomes more sensitive, and potential weak links can be discovered early;

[0056] Under multi-directional forces, the overall stability of the curtain wall body and the reliability of the connection nodes are tested, which can effectively verify the rationality of the curtain wall design and the construction quality, and ensure the integrity of the structure under extreme load conditions. The test results can reveal the performance differences of different materials and designs under complex stress states, and provide a basis for selecting more suitable curtain wall materials, optimizing structural design, and enhancing connection methods.

[0057] Simulating the extreme load conditions that may be encountered in reality can more accurately predict the performance of the curtain wall throughout its life cycle, including durability, deformation resistance and damage accumulation.

[0058] The support mechanism 4 includes a pressure plate 41, which is fixedly mounted on the inner wall of the support frame 2. Two mounting frames 46 are symmetrically arranged at the bottom of the pressure plate 41. The insides of the two mounting frames 46 are both provided with first telescopic rods 47. The two mounting frames 46 are both fixedly connected to the support frame 2. Four mounting grooves 43 are opened at the upper end of the pressure plate 41. Four first clamping blocks 42 for clamping the curtain wall body 5 are arranged on the inner wall of the pressure plate 41.

[0059] The pressure mechanism 3 includes a hydraulic rod 31 installed inside the test box 1, a pressure plate 32 is provided at the bottom of the hydraulic rod 31, an arc groove 33 is opened inside the pressure plate 32, an outer retaining ring 39 is provided at the bottom of the pressure plate 32, a ring block 35 is rotatably installed inside the outer retaining ring 39, a push rod 34 is provided at the upper end of the ring block 35, and the push rod 34 is located inside the arc groove 33, a retaining ring 37 is provided at the bottom of the ring block 35, and two side plates 36 are symmetrically provided on the outer surface of the retaining ring 37, and a plurality of protrusions 38 are provided at the bottom of the two side plates 36 and the retaining ring 37.

[0060] It is worth noting that when in use, the curtain wall body 5 is placed in the first clamping block 42, and then the curtain wall body 5 is fixed by a bolt locking structure. The first clamping block 42 is a wall panel installation device in the prior art and will not be described again. After the curtain wall body 5 is installed, the hydraulic rod 31 is moved downward to push the pressure plate 32 to move downward. The movement of the pressure plate 32 will push the outer clamping ring 39 to drive the ring block 35 and the clamping ring 37 to move downward, and the clamping ring 37 drives the side plate 36 to move downward to squeeze the curtain wall body 5. The bottom of the side plate 36 and the ring block 35 are provided with a protrusion 38, and the protrusion 38 contacts the curtain wall body 5 to apply uneven normal stress to the surface of the curtain wall body 5.

[0061] The user can also push the push rod 34 to slide inside the arc groove 33, and the push rod 34 pushes the ring block 35 to slide inside the outer clamping ring 39. By rotating the ring block 35 to change the position of the protrusion 38, the curtain wall body 5 can be subjected to different forces, resulting in one side of the curtain wall body 5 being compressed while the other side is relatively free from force. This uneven pressure causes the curtain wall body 5 to bend toward the side subjected to force, forming a deflection or bending moment, and a larger compressive stress is generated on the side subjected to force, and a tensile stress is generated on the other side. Due to the uneven stress distribution of the curtain wall body 5, stress concentration will occur near the edge and force points of the curtain wall body 5.

[0062] Among them, by adjusting the position of the protrusion 38, uneven pressures of different distributions can be applied to the curtain wall body 5. The flexibility of adjusting the position of the protrusion 38 can simulate the stress state under various actual working conditions, including local concentrated loads and asymmetric loads, thereby improving the practicality and extensiveness of the test.

[0063] Moreover, the stress concentration phenomenon caused by uneven normal stress can effectively detect the local strength and stability of the curtain wall body under extreme or abnormal stress conditions, helping to identify and prevent potential local damage risks;

[0064] When bending or deflecting under stress, the elastoplastic behavior, ultimate bearing capacity and deformation recovery performance of the curtain wall material can be deeply evaluated to ensure the reliability and durability of the curtain wall in normal use and under extreme conditions.

[0065] The compressive stress testing mechanism 7 comprises a bottom plate 73 , the upper end of which is provided with four stress arc grooves 74 , and the round rod 63 is located inside the stress arc grooves 74 , and the stress arc grooves 74 are used to control the moving position of the round rod 63 .

[0066] Two supporting plates 44 are symmetrically arranged on the bottom wall of the pressure plate 41 . Limiting slot plates 45 are arranged on both sides of the two supporting plates 44 , and the limiting slot plates 45 correspond to the positions of the installation slots 43 .

[0067] The angle clamping mechanism 6 includes a second clamping block 61 for clamping the corners of the curtain wall body 5. A slider 62 is provided at the bottom of the second clamping block 61. A round rod 63 is provided at the bottom of the slider 62. The slider 62 is slidably installed inside the limiting slot plate 45, and the second clamping block 61 is located inside the mounting slot 43.

[0068] It is worth noting that the first telescopic rod 47 pushes the bottom plate 73 to rotate, and the stress arc groove 74 opened inside the bottom plate 73 is Fig.13The shape shown in the figure, by rotating the bottom plate 73, the position of the stress arc groove 74 is changed, and the change in the position of the stress arc groove 74 will cause the round rod 63 to move along the direction limited by the limiting slot plate 45. The designed curvature of the stress arc groove 74 can apply force to the second clamping block 61 by extrusion, thereby pushing the second clamping block 61 to apply pressure to the center of the curtain wall body 5. When the direction of the force applied by the second clamping block 61 to the four corners of the curtain wall body 5 is the extrusion force toward the center of the curtain wall body 5, the force exerted on each corner of the curtain wall body 5 converges toward the center, and a compressive stress field from the surroundings to the center will be generated inside the curtain wall body 5. The central area will be subjected to a higher compressive stress, and the curtain wall body 5 will be compressed in four directions at the same time.

[0069] Among them, by adjusting the position of the stress arc groove 74, the direction and distribution of the pressure applied to the four corners of the curtain wall body 5 are dynamically changed, so that the complex stress state of different angles and distributions can be simulated. The adjustable design of the stress arc groove 74 allows the tester to accurately control the force application process and gradually increase or change the pressure, so as to analyze the response of the curtain wall at different pressure stages in detail and obtain detailed data on the curtain wall performance.

[0070] Since the forces converge toward the center of the curtain wall body 5, the central area is subjected to higher compressive stress. This test is particularly helpful in evaluating the bearing capacity and stability of the core area of ​​the curtain wall, and detecting whether the curtain wall will collapse or be damaged in the center under extreme loads.

[0071] The compressive stress testing mechanism 7 also includes a groove ring 72, and two connecting plates 71 are symmetrically arranged on the outer surface of the groove ring 72. One end of the two connecting plates 71 is fixedly connected to the mounting frame 46. A mounting ring 75 is rotatably installed inside the groove ring 72, and a mounting cylinder 76 is fixedly installed on the inner wall of the mounting ring 75. A bottom film 77 is arranged at the bottom of the mounting cylinder 76, and a bottom plate 73 is fixedly installed on the upper end of the mounting cylinder 76.

[0072] A rotating block is symmetrically provided at the lower end of the bottom plate 73 , and the bottom plate 73 is rotatably connected to the first telescopic rod 47 via the rotating block.

[0073] An inner ring 78 is provided on the upper inner wall of the mounting tube 76, a rubber ring 79 is provided on the upper end of the inner ring 78, a spring 713 is provided inside the rubber ring 79, a detector 711 is provided on the upper end of the rubber ring 79, a second telescopic rod 714 is provided in the middle of the upper end of the bottom film 77, and a top block 712 is provided on the upper end of the second telescopic rod 714.

[0074] It is worth noting that when the curtain wall body 5 is installed inside the supporting mechanism 4, the detector 711 is attached to the bottom of the curtain wall body 5, and a spring 713 is provided at the bottom of the detector 711 to push the detector 711 to move upward, so that the detector 711 contacts the curtain wall body 5, and the detector 711 is one of the metal induction sensor, pressure sensor and ultrasonic sensor in the prior art. The detector 711 is used to detect the stress of the curtain wall body 5, and the spring 713 is provided to allow the spring 713 to contact the bottom of the curtain wall body 5;

[0075] When the pressure mechanism 3 applies pressure downward to the curtain wall body 5, the second telescopic rod 714 extends to push the top block 712 to move upward, and the top block 712 contacts the curtain wall body 5, applying upward pressure to the bottom of the curtain wall body 5. The pressure mechanism 3 and the second telescopic rod 714 simultaneously apply pressure to the curtain wall body 5 to form a stress state similar to extrusion. The upward force at the bottom center of the curtain wall body 5 and the downward force at the top periphery act together to compress the curtain wall body 5 in the vertical direction and generate a closed stress state in the horizontal direction. The central area of ​​the curtain wall body 5 will be subjected to compressive stress, while the periphery, especially the top periphery, will be subjected to a complex stress state. This pressurization method causes the curtain wall body 5 to present a complex deformation mode, including compression and local distortion or warping.

[0076] The top block 712 can apply pressure to the curtain wall body 5 alone. The top block 712 presses the curtain wall body 5 upward, so that the force on the curtain wall body 5 is evenly distributed on the curtain wall body 5, resulting in similar elastic or plastic deformation in the central area and the peripheral area of ​​the curtain wall body 5. In addition, the present invention provides a variety of testing methods to comprehensively detect the pressure resistance of the curtain wall body 5.

[0077] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to replace some of the technical features therein. Any modification, replacement, and improvement made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
