Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a device for uniformly, quickly and vertically positioning a concrete rebound hammer. Background Technique

[0002] A concrete rebound hammer is a tool for detecting the strength of building components. It is necessary to ensure correct operation to guarantee accuracy. First, select the test position. The distances between the upper, lower, left and right edges of the test area and the edge or joint of the component should not be greater than 500 mm and not less than 200 mm. Divide it into 16 test blocks. Hold the rebound hammer firmly with both hands, keep the axis perpendicular to the test surface, push it forward evenly and slowly, and quickly read the rebound value. During the pushing process, inaccurate test results are often caused by hand shaking, delaying the construction progress.

[0003] For example, in a positioning device for a concrete rebound hammer described in the patent with the patent publication number CN220170703U, through the mutual cooperation of an integrated positioning plate and a hydraulic cylinder, the positioning and operation of the concrete rebound hammer perpendicular to the plane to be measured are realized. The stability and perpendicularity of the device are ensured through the positioning plate. Pushing the connecting rod can accurately push out the rebound hammer, and the operation is simple and the structure is compact. The hydraulic cylinder drives the arc plate to clamp or release the rebound hammer, and the contraction of the hydraulic rod can quickly complete the disassembly of the rebound hammer, greatly improving the convenience of use and the ease of maintenance. In addition, the equipped laser lamp auxiliary observation function enables the staff to immediately judge whether the rebound hammer is vertically arranged on the positioning frame. This positioning device for a concrete rebound hammer needs to select a test position on the surface of the component to be measured before selecting the test area, and it is easy to have errors by fitting the positioning plate to the wall surface. The work efficiency is low by constantly disassembling and installing the equipment and placing it in the test area.

[0004] Based on this, a device for uniformly, quickly and vertically positioning a concrete rebound hammer is now provided, which can eliminate the drawbacks of existing devices. Content of the Utility Model

[0005] The purpose of the utility model is to provide a device for uniformly, quickly and vertically positioning a concrete rebound hammer to solve the problems in the background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A device for uniformly, quickly and vertically positioning a concrete rebound hammer, comprising a limiting square plate. The interior of the limiting square plate is evenly divided into sixteen rebound hammer limiting grooves. At the lower end of the limiting square plate, there are two first scale blocks for measuring the height of the limiting square plate. The first scale blocks are slidably connected to sleeves. At the lower end of the sleeves, there are support seats that fit against the wall to facilitate the limiting square plate to fit against the wall. Inside the rebound hammer limiting grooves, there is a limiting mechanism for keeping the rebound hammer body perpendicular to the wall during testing. At the upper end of the support seat, there is a telescopic structure for extending or shortening the first scale blocks.

[0026] In order to make the purpose, technical solutions and advantages of the utility model more clear and understandable, the following further details the utility model in conjunction with the drawings and embodiments.

[0027] In one embodiment, asFigures 1 - 3 As shown in the figure, a device for uniformly and quickly vertically positioning a concrete rebound hammer includes a limiting square plate 101. The inside of the limiting square plate 101 is evenly divided into sixteen rebound hammer limiting grooves. At the lower end of the limiting square plate 101, there are two first scale blocks 102 for measuring the height of the limiting square plate 101. The first scale blocks 102 are slidably connected to a sleeve 103. At the lower end of the sleeve 103, there is a support base 104 that fits against the wall to facilitate the limiting square plate 101 to fit against the wall. Inside the rebound hammer limiting grooves, there is a limiting mechanism for keeping the rebound hammer body 106 perpendicular to the wall during testing. At the upper end of the support base 104, there is a telescopic structure for extending or shortening the first scale blocks 102. At the upper end of the limiting square plate 101, there is a ranging component for facilitating the measurement of the position between the limiting square plate 101 and the edge of the wall. When selecting a measurement area, to make the test results accurate, the distances between the upper, lower, left, and right edges of the test area and the edge or joint of the component should not be greater than 500 mm and not less than 200 mm. The height of the limiting square plate 101 is adjusted by the first scale blocks 102 below the limiting square plate 101 to keep the limiting square plate 101 within a suitable test area. The repeated test areas are divided by the sixteen rebound hammer limiting grooves evenly divided inside the limiting square plate 101, which is more accurate and convenient than the traditional method of using a ruler and pen for distance measurement and division. By making the support base 104 closely adhere to the wall, the limiting square plate 101 can naturally fit against the wall. The balance block 105 provides a supporting force to prevent the limiting square plate 101 from tipping forward during the testing process of the rebound hammer body 106;

[0028] In one embodiment, as Figure 2 shown, the limiting mechanism includes a positioning tube 201. Inside each rebound hammer limiting groove, a positioning tube 201 is fixedly connected. On the inner wall of the positioning tube 201, there are four first slide rails 202. The first slide rails 202 are slidably connected to a sliding part that keeps the test end of the rebound hammer body 106 perpendicular to the wall when the rebound hammer body 106 moves towards the test wall. The fixed conditions are provided by the positioning tubes 201 provided inside each rebound hammer limiting groove. Through the positioning tubes 201 and the four first slide rails 202 fixedly connected to the inner wall of each positioning tube 201, the port of the rebound hammer body 106 always remains at the center of the positioning tube 201 during movement, increasing the test accuracy;

[0029] In one embodiment, as Figure 2As shown, the sliding member includes a first slide rail 202. The first slide rail 202 is slidably connected to a first sliding block 203. A sleeve 204 is fixedly connected between the four first slide rails 202. The sleeve 204 is adapted to the test end of the rebound hammer body 106. By inserting the test end of the rebound hammer body 106 into the interior of the sleeve 204 and pushing the rebound hammer body 106 forward, the sleeve 204 slides in the positioning tube 201 through the first slide rail 202, causing the rebound hammer body 106 to move in a straight line. The test end of the rebound hammer body 106 is kept perpendicular to the wall surface by fitting the limiting square plate 101 to the wall surface;

[0030] In one embodiment, as Figure 3 shown, the telescopic structure includes a sliding groove 306. The sliding groove 306 is fixedly connected to the upper end of the support base 104. The sliding groove 306 is slidably connected to a second sliding block 305. A ranging plate 307 is fixedly connected to the upper end of the second sliding block 305. A first scale block 102 is fixedly connected to each of the left and right ends of the ranging plate 307. A driving element for driving the second sliding block 305 to slide in the sliding groove 306 is provided on the side surface of the second sliding block 305. By providing the sliding condition through the sliding groove 306, the ranging plate 307 is driven to move up and down by the sliding of the second sliding block 305 in the sliding groove 306, and the two first scale blocks 102 are driven to slide in the sleeve 103 by the ranging plate 307, so as to realize the adjustment of the height of the limiting square plate 101;

[0031] In one embodiment, as Figure 3 and Figure 4 shown, the driving element includes a rack 304. The rack 304 is fixedly connected to the side surface of the second sliding block 305. A gear 302 meshing with the rack 304 is provided on the side surface of the rack 304. The gear 302 is fixedly connected to the output end of a stepping motor 301. A fixed seat 303 is fixedly connected to the lower end of the stepping motor 301. The lower end of the fixed seat 303 is fixedly connected to the upper end of the support base 104. Fixing is provided through the fixed seat 303, and power is provided by the stepping motor 301. The stepping motor 301 drives the gear 302 to rotate, and the gear 302 drives the rack 304 to move, so that the rack 304 drives the second sliding block 305 to slide in the sliding groove 306, providing power for the movement of the second sliding block 305;

[0032] In one embodiment, as Figure 1 and Figure 5 shown, the ranging assembly includes a second slide rail 401. The second slide rail 401 is fixedly connected to the upper end of the limiting square plate 101. The second slide rail 401 is slidably connected to a second scale block 402. By sliding the second scale block 402 inside the second slide rail 401, the distance between the edge line of the test area of the limiting square plate 101 and the edge or joint of the component is measured to find the best test area.

[0033] The above embodiments disclose a device for uniformly, quickly, and vertically positioning a concrete rebound hammer. Among them, when selecting a test area, to ensure accurate test results, the distances between the upper, lower, left, and right edges of the test area and the edges or joints of the component should be not greater than 500 mm and not less than 200 mm. By moving the second ruler block 402, the distance between the edge of the test area of the limit square plate 101 and the edge or joint of the component is measured by the second ruler block 402 to find the optimal test area. The stepping motor 301 provides power. The stepping motor 301 drives the gear 302 to rotate, and the gear 302 drives the rack 304 to move, so that the rack 304 drives the second sliding block 305 to slide in the sliding groove 306, providing power for the movement of the second sliding block 305. The up-and-down translation of the ranging plate 307 is driven by the sliding of the second sliding block 305 in the sliding groove 306. The two first ruler blocks 102 are driven to slide in the sleeves 103 by the ranging plate 307, realizing the adjustment of the height of the limit square plate 101. When the test area is determined, the test end of the rebound hammer body 106 is inserted into the inside of the sleeve 204, and the rebound hammer body 106 is pushed forward. The sleeve 204 slides in the positioning tube 201 through the first slide rail 202, making the rebound hammer body 106 move in a straight line. The test end of the rebound hammer body 106 is kept perpendicular to the wall by the close fit of the limit square plate 101 with the wall. The data obtained by the rebound hammer body 106 is recorded, and the above test steps are repeated in the sixteen rebound hammer limiting grooves, and the test is completed.

[0034] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, which should all be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
