TECHNICAL FIELD

[0001] The present application relates to the technical field of strength detection, in particular to a new type of material fireproof plate strength detection device for building. BACKGROUND

[0002] With the upgrading of building safety standards, new fireproof plates are widely used because they have both fireproof and structural functions. However, the structure of such materials is diverse, and conventional detection has limitations. Existing devices mostly use fixed contact area testing, which cannot distinguish between local compression resistance and overall load-bearing performance, leading to data confusion. Errors occur during bending testing due to unstable contact, and the device cannot simulate complex stress scenarios in actual buildings. In addition, traditional equipment cannot comprehensively evaluate the high-temperature stability and mechanical strength of fireproof plates, and cannot meet the needs of new materials for detection accuracy and scene adaptability. Therefore, a targeted strength detection device is urgently needed.

DETAILED DESCRIPTION

[0014] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0015] Please refer to Figures 1-7 An embodiment of the present application is: a new building material fireproof plate strength detection device, which comprises a base 1, the top of the base 1 is fixedly connected with a support frame 2, the inner wall of the support frame 2 is fixedly connected with an electric cylinder 3, the top of the base 1 is fixedly connected with an arc table 4, the output end of the electric cylinder 3 is fixedly connected with a pressing plate 7, the top of the pressing plate 7 is fixedly connected with an elastic telescopic rod one 8, the telescopic end of the elastic telescopic rod one 8 is fixedly connected with a connecting plate 9, the bottom of the connecting plate 9 is fixedly connected with a fixed column 10, the circumferential surface of the fixed column 10 is fixedly connected with a pressing block 11, the front part of the pressing plate 7 is fixedly connected with a frame 12, the circumferential surface of the frame 12 is rotatably connected with a pull rod 13, the inner wall of the pull rod 13 is fixedly connected with a half-arc plate 14, the inner wall of the support frame 2 is fixedly connected with a displacement sensor, the inner wall of the arc table 4 is rotatably connected with a hinged column 15 through a torsion spring, the circumferential surface of the hinged column 15 is fixedly connected with a positioning plate 16, the top of the positioning plate 16 is fixedly placed with a plate, the inner wall of the base 1 is fixedly connected with a motor; When the device starts, the operator first needs to place the new material fireproof plate to be tested for compressive strength on the top of the positioning plate 16. When the new material fireproof plate is placed, the electric cylinder 3 will start, and the extension end of the electric cylinder 3 will drive the pressing plate 7 to move downward. The downward movement of the pressing plate 7 will drive the elastic extension rod 8 to move, and the movement of the elastic extension rod 8 will drive the connecting plate 9 to move. The movement of the connecting plate 9 will drive the fixed column 10 to move, and the movement of the fixed column 10 will drive the pressing block 11 to move. When the pressing block 11 moves downward by a distance, the pressing block 11 will contact the plate placed on the top of the positioning plate 16. At this time, the electric cylinder 3 will continue to indirectly drive the pressing block 11 to move downward. After the pressing block 11 contacts the plate placed on the top of the positioning plate 16, the pressing block 11 will exert a certain pressure on the plate, and at the same time, the plate will exert a counterforce on the pressing block 11 during the downward movement of the pressing block 11. At this time, the pressing block 11 will move upward after being subjected to the counterforce of the plate. The upward movement of the pressing block 11 will drive the fixed column 10 to move upward. When the pressing block 11 moves upward by a certain distance, the pressing block 11 will enter the inner wall of the pressing plate 7, and the pressing plate 7 will contact the plate and exert pressure on the center of the plate. At this time, the pressing plate 7 will push the plate to bend. During the bending of the plate, the plate will simultaneously extrude the positioning plate 16 to rotate until the curved surface of the plate contacts the placement arc table 4. At this time, the positioning plate 16 stops rotating, and the displacement sensor can detect the surface strength of the plate during this process. The movement of the pressing plate 7 can detect the bending strength of the new material fireproof plate, realize the conversion from local compressive strength to overall compressive strength detection, accurately detect the local compressive strength, avoid interference during detection, improve the accuracy of the device in detecting the strength of the new material fireproof plate, and improve the accuracy of the strength detection data. The inner wall of the base 1 is provided with a clamping mechanism 5 for clamping the plate. The circumferential surface of the clamping mechanism 5 is provided with a lifting mechanism 6 for accelerating the removal of the plate. The fixed column 10 is slidingly connected to the inner wall of the pressing plate 7 and is used to drive the pressing block 11 to move. The fixed column 10 is located directly above the placement arc table 4 and is used to extrude the new material fireproof plate. The semi-arc plate 14 is located directly above the placement arc table 4 and is used to extrude the plate in an arc shape. The positioning plate 16 contacts the placement arc table 4 and is used for quick positioning when the plate is placed. When the device is in use, the downward movement of the pressing plate 7 drives the frame 12 to move downward, and the downward movement of the frame 12 drives the pull rod 13 to move downward, and the downward movement of the pull rod 13 drives the semicircular plate 14 to move downward. When the semicircular plate 14 moves a distance, the arc surface of the semicircular plate 14 will contact the surface of the plate. At this time, the frame 12 will continue to drive the semicircular plate 14 to move downward. The semicircular plate 14 will slide on the surface of the plate during the downward movement of the frame 12, until the pressing plate 7 contacts the plate, and then stops. After the pressing plate 7 exerts pressure on the plate, the two sides of the plate will be bent and raised to a certain extent by the arc design of the arc table 4. During the bending and raising of the plate, the arc surface of the semicircular plate 14 will fit and press the arc surface of the two sides of the plate. The semicircular plate 14 can avoid local stress concentration, ensure the real controllability of the failure mode, simulate the actual bending scene, improve the scene adaptability of the device detection, stabilize the bending form, and facilitate accurate measurement of deformation parameters.

[0016] The overall working principle is that the plate will synchronously extrude the positioning plate 16 to rotate until the arc surface of the plate contacts the arc table 4. At this time, the positioning plate 16 stops rotating, and the displacement sensor can detect the surface strength of the plate during this process. The movement of the pressing plate 7 can detect the bending strength of the new type of fireproof plate, realize the conversion from local compressive strength detection to overall compressive strength detection, accurately detect the local compressive strength, avoid detection interference, improve the accuracy of the device for detecting the strength of the new type of fireproof plate, improve the data accuracy of the strength detection, and facilitate accurate measurement of deformation parameters.

[0017] Please refer to Figures 1-7 On the basis of the above embodiment, in another embodiment of the present application, the clamping mechanism 5 comprises a reciprocating screw rod 501, a limiting column 502, a moving rod 503, an elastic telescopic rod two 504, and an arc clamping plate 505. The reciprocating screw rod 501 is rotationally connected to the inner wall of the base 1. The limiting column 502 is fixedly connected to the inner wall of the base 1. The moving rod 503 is movably connected to the circumferential surface of the reciprocating screw rod 501. The elastic telescopic rod two 504 is fixedly connected to the right side of the moving rod 503. The arc clamping plate 505 is fixedly connected to the telescopic end of the elastic telescopic rod two 504. During the use of this device, after the pressure plate 7 compresses and bends the plate, the motor starts, and the motor output drives the reciprocating screw 501 to rotate. The rotation of the reciprocating screw 501 drives the moving rod 503 to rotate. However, during the rotation of the reciprocating screw 501, the moving rod 503 is limited by the limiting post 502. The limiting post 502 causes the moving rod 503 to only move through the reciprocating groove on the surface of the reciprocating screw 501 during the rotation of the reciprocating screw 501. The reciprocating lateral movement of the moving rod 503 will cause the elastic telescopic rod 504 to move, which in turn will cause the arc clamping plate 505 to move. After moving a certain distance, the arc clamping plate 505 will contact and clamp the two sides of the bent plate. The clamping of the arc clamping plate 505 can prevent the plate from moving on its own during the strength bending test, avoid the decrease in test accuracy caused by the movement of the plate, and improve the authenticity of the device for the strength test of new fireproof board materials. The clamping mechanism 5 also includes a third elastic telescopic rod 506, a fixing block 507, a first rack 508, a connecting column 509, a gear 510, an L-shaped rod 511, a second rack 512, and a pressing column 514.

During the movement and bending of the plate, the plate will squeeze and push the rack one 508 to move downward. During the downward movement of the rack one 508, the rack one 508 will synchronously drive the gear 510 to rotate due to the meshing of the rack one 508 and the gear 510. The rotation of the gear 510 will drive the rack two 512 to rise. The rising of the rack two 512 will drive the L-shaped rod 511 to rise. During the rising of the L-shaped rod 511, the L-shaped rod 511 will contact the pressing column 514. At this time, the L-shaped rod 511 can push the pressing column 514 to rotate. After the pressing column 514 rotates by a certain angle, the pressing column 514 will press the two ends of the bent plate to prevent the two ends of the plate from being too raised during the bending process, causing stress concentration and affecting the accuracy of the overall pressure strength detection data of the plate. At the same time, the pressure strength of the two ends of the plate can be detected. The lifting mechanism 6 comprises a groove block 601, an inclined plate 602 and a roller column 603.

When the arc clamping plate 505 is reset, the operator can manually rotate the inclined plate 602 and contact the arc table 4. During the rotation of the inclined plate 602, the inclined plate 602 will drive the roller column 603 to rotate and move. After rotation, the operator can pull the plate through the inclined surface of the inclined plate 602 and contact the roller column 603. At this time, the plate continues to move, and the roller column 603 will rotate due to the friction generated by the contact with the plate. The roller column 603 can reduce the friction of the plate movement, speed up the removal speed of the detected plate, and indirectly improve the detection efficiency of the device. The lifting mechanism 6 further comprises an elastic telescopic rod four 604, a protrusion one 605, a sliding column 606 and a protrusion two 607.
