Abstract
Description
Technical Field
[0001] This invention relates to the field of strength testing technology for shear wall construction, specifically to a strength testing device for shear wall construction. Background Technology
[0002] A shear wall construction strength testing device is a specialized device used to monitor the strength development of shear wall concrete after pouring and to verify whether it meets design requirements. The common operating principle of such devices is that an internal impact structure is pressed against the concrete surface, causing an internal spring to release and drive a hammer to strike the impact structure with constant energy. This reflects the different hardnesses of the concrete. The different rebound distances from the concrete surface of different strengths are used to derive the shear wall strength test value. Utilizing the impact of the elastic force to obtain the test value conforms to the basic operating principle of mechanical sensors, making the shear wall construction strength testing device one of the common mechanical measurement devices.
[0003] However, during the testing of shear walls, the strength testing device used in shear wall construction may not be able to maintain a perpendicular position to the wall surface. This can affect the accuracy of the test. When the testing device is not perpendicular to the wall surface, some of the impact energy of the impact structure will be decomposed in the direction parallel to the wall surface, reducing the effective impact and rebound energy. This results in a smaller rebound distance displayed by the testing device, which in turn leads to inaccurate test results.
[0004] To address the aforementioned issues, we propose a strength testing device for shear wall construction. Summary of the Invention

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.
[0024] Please see Figures 1 to 11 This embodiment of a shear wall construction strength testing device includes a testing body 1.

An annular cavity 5 is formed inside the fixing ring 4, and compression fixing components 6 are provided on opposite sides of the inner wall of the annular cavity 5. Two supporting horizontal plates 8 are fixedly installed on the side of the fixing ring 4 near the output end of the testing body 1. Connecting components 9 are provided on the side of the two supporting horizontal plates 8 away from the testing body 1, and connecting shafts 1 are provided on opposite sides of the two connecting components 9. 0, while the two connecting shafts 10 are fixedly installed on opposite sides with adjusting rings 11.

The sponge ring 1101 is designed to better adapt to the contact between the adjusting ring 11 and the wall, ensuring the stability of the adjusting ring 11 during the contact process with the wall.
[0025] The compression fixing assembly 6 includes a push port 601 opened on one side of the inner wall of the annular cavity 5. A push block 602 is slidably mounted on the inner wall of the push port 601. A pull ring 603 is fixedly mounted on opposite sides of the two push blocks 602. The inner wall of the pull ring 603 is slidably connected to the surface of the detection body 1. A guide rod 604 is slidably mounted inside the push block 602. The opposite ends of the guide rod 604 are fixedly connected to opposite sides of the inner wall of the annular cavity 5. A push spring 605 is sleeved on one side of the guide rod 604 wall, away from the pull ring 603. On one side, the inner wall of the annular cavity 5, away from the push port 601, has a squeezing port 606. A spring plate 607 is fixedly installed on the inner wall of the squeezing port 606. The spring plate 607 ensures that the fixed ring 4 is in a stable state when the adjusting ring 11 is being adjusted. This prevents the fixed ring 4 from shaking or moving during the adjustment process, thus ensuring the stability of the device during use. The surface of the spring plate 607 contacts the surface of the push block 602 through a number of rotating connecting balls 6071. The surface of the push block 602 is provided with a snap-fit component 7 on one side of the guide rod 604.
[0026] The snap-fit assembly 7 includes a support groove block 701 fixedly installed on one side of the surface of the push block 602, and a first snap-fit plate 702 is rotatably installed on the inner wall of the support groove block 701. A second snap-fit plate 703 is fixedly installed on one side of the inner wall of the annular cavity 5, which is located on the side of the first snap-fit plate 702. The first snap-fit plate 702 and the second snap-fit plate 703 are set at the same height, and the vertical projections of the first snap-fit plate 702 and the second snap-fit plate 703 are on the same straight line. The structure of the snap-fit plates is on the same level, which can ensure the normal snap-fit effect of the two structures. A tension spring 704 is fixedly installed on the side of the second snap-fit plate 703 near the guide rod 604. One end of the tension spring 704 is fixedly connected to the surface of the push block 602. The tension spring 704 ensures the strong snap-fit effect between the snap-fit plates. A pulling vertical rod 705 is rotatably installed on the top surface of the first snap-fit plate 702, and one end of the pulling vertical rod 705 extends through to the surface of the fixed ring 4.
[0027] The connecting assembly 9 includes a connecting block 901 fixedly installed on one side of the surface of the supporting horizontal plate 8. A movable cavity 902 is formed inside the connecting block 901 around the fastening bolt 12. Movable plates 903 are slidably installed on both the upper and lower sides of the inner wall of the movable cavity 902. Two fixed vertical blocks 904 are fixedly installed on the side of the two movable plates 903 away from the fastening bolt 12. A first embedded wheel 905 is rotatably installed on the opposite sides of the two fixed vertical blocks 904. A pressing arc block 906 is fixedly installed on the side of the movable plate 903 away from the fixed vertical blocks 904. The surface of 06 extends through to the surface of the fastening bolt 12, and the inner wall of the extrusion arc block 906 is frosted. The inner wall of the moving cavity 902 is provided with a tensioning assembly 13 for tensioning the wire on the side away from the supporting horizontal plate 8. The four corners of the moving plate 903 away from the extrusion arc block 906 are fixedly connected to the inner wall of the moving cavity 902 by a reset spring 14. The tension of the reset spring 14 can ensure that the two moving plates 903 are in the unfolded state when the cable 1306 is slack, thereby ensuring the movement and rotation effect of the adjustment ring 11 when adjusting the adjustment ring 11, and ensuring the normal operation of the device.
[0028] The tensioning assembly 13 includes a telescopic groove 1301 formed on one side of the inner wall of the moving cavity 902. A telescopic plate 1302 is slidably installed within the inner wall of the telescopic groove 1301. The body of the telescopic plate 1302 is flat, and a rectangular block is protruding from each of the four corner areas of the body. The four rectangular blocks have the same structure. This telescopic plate 1302 can ensure stability during movement. Four damping springs 1303 are fixedly installed on the side of the telescopic plate 1302 near the moving plate 903. The damping springs 1303 are located in the four corner areas of the telescopic plate 1302. The telescopic ends of the four damping springs 1303 are fixedly installed with a slotted frame block 1304. A second embedded wheel 1305 is rotatably installed on the inner wall of the slotted frame block 1304. The first embedded wheel 905 and the second embedded wheel 1305 are connected to a cable 1306. One end of the cable 1306 passes through the surface of the moving cavity 902, the supporting cross plate 8, and the surface of the fixing ring 4. The cable 1306 extends to the inner wall of the annular cavity 5 and is fixedly connected to the surface of the push block 602. The cable 1306 and the two embedded wheel structures are connected by an S-shaped winding. This ensures that the cable 1306 is always in a tight state under the elastic compression of the tensioning assembly 13. It also utilizes the elastic connection effect of the tensioning structure to avoid damage to the fastening bolt 12 during compression. The other end of the cable 1306 is fixedly connected to the inner wall of the moving cavity 902. An adjusting bolt 1307 is threaded at the center of the surface of the telescopic plate 1302. The rod wall of the adjusting bolt 1307 is rotatably connected to the inner wall of the telescopic groove 1301. By using the setting of the adjusting bolt 1307, the thrust of the damping spring 1303 can be adjusted, thereby adjusting the fastening strength of the fastening bolt 12. Furthermore, the end of the adjusting bolt 1307 in this application is set as an enlarged end structure, which can avoid the problem of the adjusting bolt 1307 falling off during use and ensure the normal use function of the internal structure of the device.
[0029] The working principle of the above embodiments is as follows: When the device is in use, it will test the concrete shear wall through the elastic rebound function of the testing body 1 to ensure the strength test effect of the shear wall after construction. The testing body 1 has the function of a concrete rebound hammer, which is a mature existing technology. This application will not elaborate on the mature existing technology. The testing body 1 can ensure the effect of the mechanical structure of this application in testing the strength of the shear wall through the elastic tapping structure of the inner wall. Before the detection body 1 is tested, the adjusting ring 11 will come into contact with the wall during the process of pressing the detection body 1. However, the vertical effect between the detection body 1 and the wall cannot be guaranteed during the testing process. Therefore, the operator needs to adjust the horizontal effect between the detection body 1 and the wall first. Here, the horizontal alarm function between the tilt sensor 2 and the alarm 3 can be used to ensure the vertical and horizontal effect of the detection body 1. The connection between the two support horizontal plates 8 and the adjusting ring 11 through the connecting component 9 can ensure that the detection body 1 can only rotate up and down. This can avoid the problem of the detection body 1 rotating back and forth. Furthermore, the vertical rotation is restricted by the tilt sensor 2, thereby ensuring the vertical effect between the detection body 1 and the shear wall. When the detection body 1 is not level, the alarm 3 will sound. After the operator adjusts the level of the detection body 1, the operator needs to pull the pull ring 603 to one side. This pull ring 603 will drive the push block 602 away from the adjustment ring 11. The push block 602 will then pull the embedded wheel structure through the cable 1306. Since the cable 1306 is inelastic, the tightening action of the cable 1306 will bring the squeezing arc block 906 under the moving plate 903 closer to the fastening bolt 12, thus ensuring the stability of the fastening bolt 12 at this time. Because the fastening bolt 12 can ensure the rotation effect between the connection shaft 10 and the connection block 901 while being fixed, the position of the adjustment ring 11 will be fixed under the squeezing of the squeezing arc block 906. In this way, during the detection process, the adjustment ring 11 can ensure the verticality of the detection body 1 to the wall and ensure the accuracy of the detection. During the process of pushing block 602 away from adjusting ring 11, pushing block 602 will move away from spring plate 607. Under the elastic force of spring plate 607, the clamping limit on detection body 1 can be released. In this way, detection body 1 can slide and detect within fixed ring 4 and adjusting ring 11, ensuring the detection effect. After the position of adjusting ring 11 is adjusted, under the snapping action of first snap plate 702 and second snap plate 703, the fastening bolt 12 can be squeezed and tightened, thereby ensuring the stability of the position of adjusting ring 11, and thus enabling detection of the corresponding wall surface. When the flatness of the wall surface changes too much, alarm 3 will sound, pulling out the pull rod 705, separating the first snap plate 702 and second snap plate 703. Then, under the push of push spring 605, pushing block 602 will move in the opposite direction of the above structure's running direction, thereby ensuring that the position of fastening bolt 12 can continue to rotate, thus facilitating another adjustment.
