Abstract
Description
Technical Field
[0001] This utility model relates to the field of wall testing technology, and more specifically, to wall strength testing equipment for building engineering. Background Technology
[0002] In construction projects, strength testing of walls is a crucial step, helping to ensure the structural stability and safety of buildings. The main purpose of strength testing is to determine the compressive strength of building materials (such as concrete) to ensure they meet design and construction requirements. During wall strength testing, testing personnel frequently use a digital rebound hammer, an instrument used to measure material hardness. It determines the material's hardness by measuring the magnitude of elastic deformation on the material's surface. The principle is based on the elastic deformation and rebound characteristics of materials; the hardness value is calculated by measuring the rebound height from the material's surface.
[0003] When using a rebound hammer to test the strength of a wall, it is necessary to keep the rebound hammer perpendicular to the wall. However, at most construction sites, the rebound hammer is manually held and pressed at multiple locations on the wall. This is not only time-consuming and laborious, but also causes data detection errors due to the trembling of the operator's arm or the inability to keep the rebound hammer perpendicular to the wall. Utility Model Content
[0004] This invention addresses the problems of wall strength testing equipment used in building construction being unable to maintain perpendicularity to the wall surface, and rebound hammers being unable to move independently and press against the wall surface to test wall strength.
[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution:
[0006] A wall strength testing device for building construction includes a support mechanism and a rebound hammer mounted on the support mechanism. The support mechanism includes a horizontal component for adjusting the vertical angle of the rebound hammer relative to the wall and a pushing component mounted on the horizontal component for moving the rebound hammer along the vertical direction of the horizontal component. The rebound hammer is mounted on the pushing component and is used to test the wall strength.
[0007] Furthermore, the horizontal component includes a crossbeam, a movable seat slidably disposed outside the crossbeam, and positioning plates disposed on both sides of the crossbeam, with a limiting component provided between the movable seat and the crossbeam.
[0008] Furthermore, the pushing component includes a fixed frame disposed on the top of the movable seat, a motor disposed on the outer wall of the fixed frame, a lead screw disposed on the output shaft of the motor extending to the inner side of the fixed frame, and a movable plate slidably disposed on the top of the fixed frame and threadedly connected to the lead screw.
[0009] Furthermore, the top of the movable plate is provided with a fixing assembly, which includes a fixing box disposed on the top of the movable plate, slide rods symmetrically slidably disposed on both sides of the fixing box, a clamping pad disposed at one end of the slide rod located outside the fixing box, a first spring disposed between the two opposing slide rods, a support pad disposed on the top of the fixing box, and a baffle disposed outside the fixing box.
[0010] Furthermore, the limiting component includes a bracket disposed outside the movable seat, a limiting post slidably disposed between the bracket and the movable seat, and a second spring disposed on the rod wall of the limiting post located between the movable seat and the bracket. The outer wall of the crossbeam is provided with a plurality of limiting holes that are equally distributed and cooperate with the limiting post.
[0011] Furthermore, a locking assembly is provided between the fixed frame and the movable seat. The locking assembly includes insert plates on both sides of the fixed frame, fixed plates on both sides of the top of the movable seat, and bolts threaded onto the fixed plates. The top of the movable seat has a slot that mates with the insert plates, and the side wall of the insert plates has a screw hole that mates with the bolts.
[0012] Furthermore, a spirit level is provided at the top of the fixed frame.
[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0014] 1. When testing the strength of a wall, a horizontal beam and a spirit level are used to fix the rebound hammer horizontally to the wall, keeping it perpendicular to the wall. A motor, lead screw, and moving plate then move the rebound hammer horizontally to make it perpendicular to the wall. The rebound hammer then moves in the opposite direction to reset and detach from the wall, thus completing the strength test. This method ensures that the rebound hammer makes perpendicular contact with the wall, solving the problem in existing technologies where manual contact with the wall can lead to errors that prevent the rebound hammer from making perpendicular contact, affecting the accuracy of the test data.
[0015] 2. The movable seat can move back and forth on the crossbeam, allowing for horizontal adjustment of the rebound hammer's position. The set limit components can then fix the adjusted position. This not only enables strength testing at multiple locations on the wall but also ensures that the rebound hammer remains perpendicular to the wall, improving the accuracy of the test data. Furthermore, the set locking and fixing components allow for the installation and disassembly of the support mechanism, pushing components, and rebound hammer, facilitating disassembly, storage, and transport when the equipment is not in use.

[0023] The technical solutions in the embodiments of this utility model will now be clearly and completely described in conjunction with the accompanying drawings.
[0024] like Figure 1 and Figure 2 As shown, this embodiment proposes a wall strength testing device for building engineering, including a support mechanism and a rebound hammer 1 installed on the support mechanism. The support mechanism includes a horizontal component 2 for adjusting the vertical angle of the rebound hammer 1 relative to the wall and a pushing component 3 installed on the horizontal component 2 for driving the rebound hammer 1 to move in the vertical direction of the horizontal component 2. The rebound hammer 1 is installed on the pushing component 3 and is used to test the wall strength.
[0025] When it is necessary to test the strength of the wall, the horizontal component 2 is first fixed horizontally on the wall so that the rebound hammer 1 can be kept perpendicular to the wall. Then, the push component 3 is used to move the rebound hammer 1 horizontally to make it perpendicular to the wall, which can improve the accuracy of the rebound hammer 1 test data. Moreover, the horizontal component 2 can also adjust the position of the rebound hammer 1, which is convenient for vertical testing of multiple positions on the wall. It is not necessary to manually hold the rebound hammer 1 and squeeze it to test various positions on the wall. This not only saves time and manpower, but also prevents the rebound hammer 1 from failing to make it perpendicular to the wall due to human operation errors, thus affecting the test work and improving the accuracy of the test data.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the horizontal component 2 includes a crossbeam 201, a movable seat 202 slidably disposed outside the crossbeam 201, and positioning plates 203 disposed on both sides of the crossbeam 201. A limiting component 5 is provided between the movable seat 202 and the crossbeam 201, and a spirit level 7 is provided on the top of the fixed frame 301.
[0027] The limiting component 5 includes a bracket 501 disposed outside the movable seat 202, a limiting post 502 slidably disposed between the bracket 501 and the movable seat 202, and a second spring 503 disposed on the rod wall of the limiting post 502 located between the movable seat 202 and the bracket 501. The outer wall of the crossbeam 201 is provided with a plurality of equidistantly distributed limiting holes that cooperate with the limiting post 502.
[0028] First, the beam 201 is placed against the wall. The level of the beam 201 is easily adjusted using the spirit level 7 to ensure it is level with the wall. Then, the beam 201 is fixed to the wall using the positioning plate 203 and screws. This ensures that the rebound hammer 1 is perpendicular to the wall, improving the accuracy of the rebound hammer's strength testing. Furthermore, when testing the strength of other parts of the wall, the limiting post 502 is pulled to disengage it from the limiting hole on the beam 201, compressing the second spring 503. At this point, the beam 201 can be moved... When the seat 202 is released, the sliding seat 202 can be used to move the rebound spring 1 horizontally above the crossbeam 201. After the rebound spring 1 is moved to the designated position, the limiting post 502 is released. At this time, the force on the second spring 503 is released, which will cause the limiting post 502 to rebound through the sliding seat 202 and insert into the limiting hole in the crossbeam 201. This can fix the sliding seat 202 and the rebound spring 1. Therefore, it can not only test the strength of multiple positions on the wall, but also keep the rebound spring 1 relatively perpendicular to the wall, improving the accuracy of the test data.
[0029] like Figure 5 As shown, the pushing component 3 includes a fixed frame 301 disposed on the top of the movable seat 202, a motor 302 disposed on the outer wall of the fixed frame 301, a lead screw 303 disposed on the output shaft of the motor 302 extending to the inner side of the fixed frame 301, and a movable plate 304 slidably disposed on the top of the fixed frame 301 and threadedly connected to the lead screw 303.
[0030] The top of the movable plate 304 is provided with a fixing component 4. The fixing component 4 includes a fixing box 401 disposed on the top of the movable plate 304, slide rods 402 symmetrically slidably disposed on both sides of the fixing box 401, a clamping pad 403 disposed at one end of the slide rod 402 located outside the fixing box 401, a first spring 404 disposed between the two opposing slide rods 402, a support pad 405 disposed on the top of the fixing box 401, and a baffle 406 disposed outside the fixing box 401.
[0031] First, pull the sliding rods 402 on both sides of the fixing box 401 to the sides so that the two clamping pads 403 gradually move away. Then, place the rebound spring 1 on the support pad 405 and make the end of the rebound spring 1 abut against the baffle 406. Then release the sliding rods 402. At this time, the first spring 404 will drive the two sliding rods 402 to rebound and make the two clamping pads 403 abut against the two sides of the rebound spring 1 to clamp and fix the rebound spring 1, so as to facilitate the fixation of the rebound spring 1. Then, start the motor 302 to drive the lead screw 303 to rotate. The lead screw 303 will drive the fixing box 401 to move horizontally through the moving plate 304, which will drive the rebound spring 1 to abut against the wall perpendicularly. Under the obstruction of the baffle 406, the rebound spring 1 can be prevented from slipping off the clamping pads 403 due to the reverse force. Continue to drive the lead screw 303 to reverse through the motor 302, so that the rebound spring 1 moves in the opposite direction and gets off the wall, so as to detect the wall strength data.
[0032] like Figure 4 and Figure 5 As shown, a locking assembly 6 is provided between the fixed frame 301 and the movable seat 202. The locking assembly 6 includes insert plates 601 on both sides of the fixed frame 301, fixed plates 602 on both sides of the top of the movable seat 202, and bolts 603 threaded on the fixed plates 602. The top of the movable seat 202 is provided with a slot that mates with the insert plates 601, and the side wall of the insert plates 601 is provided with screw holes that mate with the bolts 603.
[0033] When it is necessary to test the strength of the wall, the insert plate 601 at the bottom of the fixed frame 301 can be inserted into the slot at the top of the movable seat 202, and then the bolt 603 can be screwed into the screw hole on the outer wall of the insert plate 601, so that the fixed frame 301 can be vertically fixed on the crossbeam 201, which facilitates the installation and disassembly of the crossbeam 201 and the fixed frame 301. Therefore, when the equipment is not in use, it is convenient to disassemble the crossbeam 201, the fixed frame 301 and the rebound hammer 1, which makes it convenient to store or carry the equipment parts.
[0034] The working principle of this utility model is as follows: When it is necessary to test the strength of the wall, firstly, pull the sliding rods 402 on both sides of the fixing box 401 to the sides so that the two clamping pads 403 gradually move away. Then, place the rebound hammer 1 on the support pad 405 and make the end of the rebound hammer 1 abut against the baffle 406. Then release the sliding rods 402. At this time, the first spring 404 will drive the two sliding rods 402 to rebound, and make the two clamping pads 403 abut against the two sides of the rebound hammer 1 to clamp and fix the rebound hammer 1. Then, the crossbeam 201 abuts against the wall. The level of the crossbeam 201 can be easily adjusted by the set bubble level 7 to keep the crossbeam 201 horizontal with the wall, so that the rebound hammer 1 can keep the wall perpendicular. Then, the motor 302 is started to drive the lead screw 303 to rotate. The lead screw 303 will drive the fixed box 401 to move horizontally through the moving plate 304, which will drive the rebound hammer 1 to come into perpendicular contact with the wall. Under the obstruction of the baffle 406, the rebound hammer 1 can be prevented from slipping off the clamping pad 403 due to the reverse force. The motor 302 continues to drive the lead screw 303 to reverse, so that the rebound hammer 1 moves in the opposite direction and gets away from the wall, thereby enabling the detection of the wall strength data. Furthermore, when it is necessary to test the strength of other locations on the wall, first pull the limiting post 502 to disengage it from the limiting hole on the beam 201 and compress the second spring 503. At this time, the movable seat 202 is released, and the movable seat 202 can be slid to drive the rebound hammer 1 to move horizontally above the beam 201. When the rebound hammer 1 is moved to the designated position, the limiting post 502 is released again. At this time, the force on the second spring 503 is released, which will cause the limiting post 502 to rebound through the movable seat 202 and insert into the limiting hole in the beam 201, thereby fixing the movable seat 202 and the rebound hammer 1. Therefore, this embodiment can not only test the strength of multiple locations on the wall, but also keep the rebound hammer 1 relatively perpendicular to the wall, improving the accuracy of the test data.
