Abstract
Description
Technical Field
[0001] This utility model relates to the field of building material testing technology, specifically to a compressive strength testing device for building materials. Background Technology
[0002] The main purpose of compressive strength testing is to test the compressive performance of building materials (such as concrete, bricks, stone, etc.) under stress, in order to assess their strength and compressive capacity. This helps to ensure that the quality of building materials meets design requirements, thereby ensuring the overall stability and safety of the building.
[0003] Chinese Patent Publication No. CN220508633U discloses a compressive strength testing device for building materials, including a box body. A door is hinged to one side of the box body. A workbench is installed below the box body, and a drive assembly is installed near the top of the workbench. A pressure block assembly is located inside the box body, and electric push rods are located on both sides of the pressure block assembly inside the box body. The pressure block assembly and the two electric push rods are connected via an adjustable lighting device. A receiving device is installed above the drive assembly. This invention, by incorporating an adjustable lighting device, allows workers to adjust the position of the pressure block assembly by manipulating a first and second geared motor when needed, thereby enabling compressive strength testing of different parts of the building materials. Furthermore, the device can be supplemented with lighting when necessary, thus improving its working capacity.
[0004] In the aforementioned prior art, building materials can be placed on a mesh plate for compressive strength testing. During the testing process, the debris generated can fall into the receiving box through the mesh plate. However, the mesh plate needs to be used to support the building materials during the compressive strength test. Making holes in the mesh plate will affect its strength. Moreover, some of the generated debris is still likely to remain in the non-perforated areas above the mesh plate, requiring manual secondary cleaning, which is quite cumbersome. Utility Model Content
[0005] To address the aforementioned technical shortcomings, the purpose of this utility model is to provide a compressive strength testing device for building materials. This addresses the problem that openings in the mesh plate of the compressive strength testing device mentioned in the background art affect its supporting strength, and that some debris generated can still easily remain on the non-opening areas above the mesh plate, requiring manual secondary cleaning.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A compressive strength testing device for building materials, comprising: A support platform, wherein an electric push rod is mounted on the support platform and a pressure plate is arranged at the output end of the electric push rod, and further includes: A protective structure, arranged on a support platform, is used to block flying debris from building materials. A material placement structure, arranged on a support platform, is used to place and support building materials; Positioning structures, placed on retaining structures, are used to restrict the position of building materials.
[0007] Preferably, the protective structure includes: The protective box is arranged on the support platform and slidably sleeved on the output end of the electric push rod, with the pressure plate located inside the protective box. A transparent cover is slidably installed on one side of the protective box; A limiting component is arranged on the transparent cover to restrict the horizontal sliding of the transparent cover.
[0008] Preferably, the limiting component includes: T-slots are formed inside the transparent cover plate; T-shaped blocks are arranged above the guard box, and the T-shaped blocks are slidably installed inside the T-slot.
[0009] Preferably, the material placement structure includes: A fixed shaft is arranged inside the support platform; The material feeding flap is rotatably mounted on a fixed shaft, and the material feeding flap is located below the baffle box; The support slide is slidably mounted inside the support platform; The receiving box is detachably installed on the support platform and is located below the support slide plate; A plug-in assembly, arranged on the support slide, is used to limit the position of the support slide.
[0010] Preferably, the plug-in assembly includes: Mounting plate, located on one side supporting the slide plate; The positioning screw is threaded inside the mounting plate. A positioning slot is formed inside the support platform, and one end of the positioning screw is movably installed in the positioning slot.
[0011] Preferably, the plug-in assembly further includes: The limiting hole is located inside the mounting plate; The limiting shaft is located on one side of the transparent cover and is movably installed inside the limiting hole.
[0012] Preferably, the material placement structure further includes: Horizontal chute, formed inside the support platform; A horizontal slide bar, arranged on one side of the support slide plate and slidably installed inside the horizontal slide groove, is used to restrict the horizontal movement of the support slide plate.
[0013] Preferably, the positioning structure includes: The limit screw is threaded and installed inside the guard box; The U-shaped frame is rotatably sleeved on one end of the limit screw, and the U-shaped frame is located inside the protective box; The adjusting screw is threaded inside the U-shaped frame; The clamp is located at one end of the adjusting screw.
[0014] The beneficial effects of this utility model are as follows: In this invention, building materials can be placed on a feeding flap. The supporting slide plate enhances the stability of the feeding flap. After the protective box is closed, the pressure plate can be controlled to descend and compress the building materials for pressure testing. When the building materials break under pressure, the protective box prevents splashing debris from leaking out. To clean up debris, simply pull the mounting plate to detach the supporting slide plate from under the feeding flap. The feeding flap will then flip downwards, allowing the debris to fall into the receiving box below for cleaning and recycling. By flipping and tilting the feeding flap, the debris inside the protective box can be cleaned more thoroughly, facilitating rapid subsequent pressure testing.
[0015] In this invention, after the building material is placed in the protective box, the clamping plate can be driven to clamp the building material by rotating the adjusting screw, and the position of the building material in the protective box can be finely adjusted by rotating the pull rod. By clamping the building material, its position can be restricted, preventing the building material from sliding or tilting during the pressure process. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] Example 1: like Figures 1 to 6 As shown, this utility model provides a compressive strength testing device for building materials, including: a support platform 1, an electric push rod 101 is provided on the support platform 1, a pressure plate 102 is arranged at the output end of the electric push rod 101, and a protective structure arranged on the support platform 1 to block flying building material fragments.
[0021] The protective structure includes a protective box 2 arranged on a support platform 1 and slidably fitted on the output end of an electric push rod 101. A pressure plate 102 is located inside the protective box 2. A transparent cover 201 is slidably installed on one side of the protective box 2. A limiting component is arranged on the transparent cover 201 to restrict the horizontal sliding of the transparent cover 201. When in use, the transparent cover 201 can be opened, and then the building materials can be placed inside the protective box 2. The pressure plate 102 is also located inside the protective box 2, thereby preventing debris from flying out when the building materials break.
[0022] Specifically, the limiting component includes a T-slot 202 formed inside the transparent cover 201 and a T-block 203 arranged above the protective box 2. The T-block 203 is slidably installed inside the T-slot 202. When the transparent cover 201 is pushed, it can slide through the T-slot 202 onto the T-block 203. The arrangement of the T-slot 202 and the T-block 203 can prevent the transparent cover 201 from falling off the protective box 2.
[0023] Example 2: Based on Example 1, in order to facilitate the cleaning of building material residue inside the protective box 2 and to support the building materials, a material placement structure for placing and supporting the building materials is arranged on the support platform 1.
[0024] The material placement structure includes a fixed shaft 3 arranged inside the support platform 1, a material placement flap 301 rotatably sleeved on the fixed shaft 3, the material placement flap 301 being located below the baffle box 2, a support slide plate 302 slidably installed inside the support platform 1, a receiving box 303 detachably installed on the support platform 1, the receiving box 303 being located below the support slide plate 302, and a plug-in component arranged on the support slide plate 302 to limit the position of the support slide plate 302. Building materials can be placed on the material placement flap 301 inside the baffle box 2. The support slide plate 302 can provide support for the material placement flap 301. When the support slide plate 302 is completely detached from below the material placement flap 301, the material placement flap 301 will be affected by the weight of the residue and flip downwards by itself, causing the residue to slide into the receiving box 303 below.
[0025] Specifically, the plug-in assembly includes a mounting plate 304 arranged on one side of the support slide plate 302, a positioning screw 305 threaded inside the mounting plate 304, and a positioning slot 306 opened inside the support platform 1. One end of the positioning screw 305 is movably installed in the positioning slot 306. By rotating the positioning screw 305, it can be moved by thread engagement with the mounting plate 304, so that the positioning screw 305 can be disengaged from the positioning slot 306, thereby releasing the restriction on the mounting plate 304.
[0026] Specifically, the plug-in assembly also includes a limiting hole 309 opened inside the mounting plate 304, and a limiting shaft 310 arranged on one side of the transparent cover plate 201 and movably installed inside the limiting hole 309. When the limiting hole 309 on the mounting plate 304 is sleeved on the limiting shaft 310, the position of the transparent cover plate 201 can be restricted to prevent the transparent cover plate 201 from sliding and loosening.
[0027] The material placement structure also includes a horizontal slide groove 307 opened inside the support platform 1, and a horizontal slide bar 308 arranged on one side of the support slide plate 302 and slidably installed inside the horizontal slide groove 307 to restrict the horizontal movement of the support slide plate 302. The horizontal slide groove 307 and the horizontal slide bar 308 can restrict the movement direction of the support slide plate 302 and provide support for the support slide plate 302.
[0028] Example 3: Based on Example 1, in order to prevent building materials from sliding or tilting during the compressive strength test, a positioning structure for limiting the position of building materials is arranged on the retaining structure.
[0029] The positioning structure includes a limiting screw 4 threaded inside the retaining box 2, a U-shaped frame 401 rotatably sleeved on one end of the limiting screw 4, the U-shaped frame 401 being located inside the retaining box 2, an adjusting screw 402 threaded inside the U-shaped frame 401, and a clamping plate 403 arranged at one end of the adjusting screw 402. Rotating the adjusting screw 402 allows it to move through its threaded engagement with the U-shaped frame 401, so that the adjusting screw 402 drives the clamping plate 403 to clamp the building material. Rotating the limiting screw 4 can drive the U-shaped frame 401 to move, thereby moving the clamped building material within the retaining box 2.
[0030] Working principle: Reference when using Figure 1First, rotate the positioning screw 305. When the positioning screw 305 rotates, it moves through the threaded engagement with the mounting plate 304, causing it to disengage from the positioning slot 306. This releases the restriction on the mounting plate 304. Then, pull the mounting plate 304. As the mounting plate 304 moves, it moves the support slide plate 302. The support slide plate 302 then moves the horizontal slide bar 308 within the horizontal slide groove 307. Here, you can slightly pull the mounting plate 304 to disengage the limiting hole 309 from the limiting shaft 310, thus releasing the restriction. The transparent cover 201 is positioned with its position restricted, while the supporting slide plate 302 is not completely removed from under the material placement flap 301. Then, by pushing the transparent cover 201, it can slide on the T-block 203 via the T-slot 202, opening the protective box 2. Building materials are then placed on the material placement flap 301 inside the protective box 2, positioning them at the U-shaped frame 401. The supporting slide plate 302 provides support for the material placement flap 301. Finally, the adjusting screw 402 is rotated, allowing it to move through its threaded engagement with the U-shaped frame 401. This causes the adjusting screw 402 to move the clamping plate 403 and compress the building material, pressing the building material onto the inner wall of the U-shaped frame 401. Rotating the limiting screw 4 allows it to move through its threaded engagement with the retaining box 2, enabling one end of the limiting screw 4 to rotate within the U-shaped frame 401 and move the U-shaped frame 401. This, in turn, moves the clamped building material within the retaining box 2, adjusting its position to align with the pressure plate 102. After placing the building material, the transparent cover 201 is pushed to close the retaining box 2, and then the mounting plate 30 is pushed in the opposite direction. 4. Reset the position by re-inserting the positioning screw 305 into the positioning slot 306 to limit the position of the mounting plate 304. At the same time, the limiting hole 309 on the mounting plate 304 will be re-fitted onto the limiting shaft 310 to limit the position of the transparent cover 201, thus closing the baffle box 2. Then, turn on the electric push rod 101 to control the pressure plate 102 to descend. The descending pressure plate 102 will squeeze the building materials to perform a pressure resistance test on the building materials. The baffle box 2 can block the debris that splashes when the building materials break, so that the debris falls onto the material placement flip plate 301.
[0031] When it is necessary to remove broken building materials, the transparent cover 201 can be opened according to the above steps to remove the broken building materials. When it is necessary to remove the residue, after releasing the restriction of the mounting plate 304, the mounting plate 304 can be pulled to drive the support slide plate 302 to completely detach from under the material placement flap 301. At this time, the material placement flap 301 will be affected by the weight of the residue and will flip downward by itself, so that the material placement flap 301 flips vertically. At this time, the residue on the material placement flap 301 will slide into the receiving box 303 below, so as to clean the residue inside the protective box 2.
[0032] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
