[0002] Construction project supervision refers to the professional service activities of qualified construction supervision companies that accept the entrustment of construction units to undertake their project management work and monitor the construction activities of contractors on behalf of the construction units. In order to ensure the strength of concrete and its project quality, compressive strength tests are conducted on concrete workpieces.

[0003] During testing, the concrete workpiece to be tested is placed at the bottom of the pressure head of the pressure testing machine, and then the test is carried out. After the test is completed, the data is recorded.

[0004] Existing test specimen placement platforms are mostly fixed structures, requiring manual placement of the test specimens under the pressure head. Operators need to repeatedly move and fine-tune the position of the specimens, and even disassemble and reassemble them multiple times. This not only consumes a lot of time and energy, but also prolongs the test preparation cycle, resulting in a significant reduction in testing efficiency and making it difficult to meet the needs of large-scale, high-efficiency testing. Therefore, a concrete testing device for construction engineering supervision is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a concrete testing device for construction engineering supervision, which aims to improve the problem in the prior art where operators need to repeatedly adjust or even disassemble and reassemble until the test piece is aligned with the pressure head, which is time-consuming, labor-intensive, and greatly reduces the testing efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a concrete testing device for construction engineering supervision, comprising a workbench, a pressure testing machine being provided on the left side of the workbench, and a fixing mechanism being provided on the upper left surface of the workbench.

[0007] The fixing mechanism includes a base plate, with connecting plates hinged to both the front and rear sides of the base plate. An L-plate is hinged to the side of the connecting plate away from the base plate. A guide assembly is provided on the bottom inner wall of the L-plate. A contact plate is provided on the top of the worktable. A telescopic plate is hinged to the left end of the worktable. A clamping plate is provided on the side of the L-plate near the base plate. An adjustment assembly is provided on the top of the L-plate. Limiting plates are hinged to both the front and rear sides of the base plate. A positioning post is elastically connected to the inner wall of the limiting plate via a connecting spring. A limiting block is fixedly connected to the top left side of the worktable.

[0009] The guide assembly includes a guide post slidably connected to the inner wall of the bottom of the L-plate, the bottom of the guide post being fixedly connected to the upper left surface of the workbench, and a support post slidably connected to the inner wall of the bottom protrusion of the base plate, the bottom end of the support post being fixedly connected to the top left side of the workbench.

[0010] As a further description of the above technical solution:

[0011] The top of the telescopic plate is hinged to the left side of the base plate.

[0012] As a further description of the above technical solution:

[0013] The outer wall of the positioning post penetrates and is slidably connected to the bottom inner wall of the limiting plate, and the bottom end of the positioning post is inserted into the inner wall of the limiting block.

[0014] As a further description of the above technical solution:

[0015] The top of the limiting block is set with a groove, and the bottom outer wall of the limiting plate matches the inner surface of the groove.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, through the cooperation between the workbench, the pressure testing machine and its fixing mechanism, the limiting position on the base plate can be quickly released by moving the positioning column upward and rotating the limiting plate. The base plate can move flexibly to the left to make room for placing the specimen. When placing the specimen, the contact plate can be pre-positioned.

[0032] 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.

[0033] Reference Figures 1-2 The present invention provides an embodiment of a concrete testing device for construction engineering supervision, comprising a workbench 1, a pressure testing machine 2 disposed on the left side of the workbench 1, and a fixing mechanism 3 disposed on the upper left side surface of the workbench 1; the fixing mechanism 3 is provided to place the concrete workpiece to be tested and to perform testing through the pressure testing machine 2, which is existing technology and will not be explained in detail here.

[0034] Reference Figures 2-4 The fixing mechanism 3 includes a base plate 301 on which the concrete workpiece to be tested can be placed. Connecting plates 304 are hinged to both the front and rear sides of the base plate 301. An L-plate 303 is hinged to the side of the connecting plate 304 away from the base plate 301. Moving the base plate 301 to the left causes the two sets of connecting plates 304 to rotate, and the two sets of L-plates 303 to spread out. A guide assembly 302 is provided on the bottom inner wall of the L-plate 303 to guide the L-plate 303 and the base plate 301. A contact plate 305 is provided on the top of the workbench 1 for pre-positioning. A telescopic plate 307 is hinged to the left end of the workbench 1. The overall length of the telescopic plate 307 can be adjusted to guide the leftward movement of the base plate 301. The worktable 1 is supported, and the concrete workpiece to be tested can be quickly placed on the base plate 301 by the operator. The right side of the workpiece contacts the left side of the contact plate 305. The L-plate 303 is provided with a clamping plate 306 on the side near the base plate 301. The two move in the same direction. The top of the L-plate 303 is provided with an adjustment component 4. The adjustment component 4 can be used to adapt to different types of concrete workpieces to be tested. The front and rear sides of the base plate 301 are hinged with limit plates 309. The inner wall of the limit plate 309 is elastically connected to the positioning column 310 through the connecting spring 311. The elasticity of the connecting spring 311 enables the positioning column 310 to have the functions of reset and limit. The top left side of the worktable 1 is fixedly connected with a limit block 308, which can cooperate with the positioning column 310.

[0035] Reference Figures 2-4The guide assembly 302 includes a guide post 3021 slidably connected to the inner wall of the bottom of the L-plate 303. The bottom of the guide post 3021 is fixedly connected to the upper left surface of the workbench 1. The guide post 3021 guides the L-plate 303, allowing it to move only back and forth. A support post 3022 is slidably connected to the inner wall of the bottom protrusion of the base plate 301. The bottom end of the support post 3022 is fixedly connected to the top left side of the workbench 1. The support post 3022 can guide the base plate 301, allowing it to move only left and right. The top of the telescopic plate 307 is hinged. The positioning post 310 is attached to the left side of the base plate 301. The hinged design avoids movement interference. The outer wall of the positioning post 310 is slidably connected to the bottom inner wall of the limiting plate 309. The bottom end of the positioning post 310 is inserted into the inner wall of the limiting block 308. The through-hole design allows for easy manual upward movement of the positioning post 310, thereby releasing the limitation of the limiting block 308. The top of the limiting block 308 is set as a groove. The bottom outer wall of the limiting plate 309 matches the inner surface of the groove. The limiting plate 309 is L-shaped, and the bottom fits with the groove to prevent the base plate 301 from moving left and right.

[0036] Reference Figure 2 and Figure 5 The adjustment component 4 includes a fixing block 401 fixedly connected to the top of the L-plate 303. A threaded rod 402 is threadedly connected to the inner wall of the fixing block 401. The side of the threaded rod 402 near the bottom plate 301 is rotatably connected to the outer wall of the clamping plate 306. The rotation of the threaded rod 402 can drive the clamping plate 306 to move for adjustment. An extension plate 403 is slidably connected to the top inner wall of the L-plate 303. The side of the extension plate 403 near the bottom plate 301 is fixedly connected to the outer wall of the clamping plate 306. The extension plate 403 allows the clamping plate 306 to have a certain length, which facilitates adjustment. The adjustment component 4 is provided in three sets. Two sets of adjustment components 4 are located on the top of the L-plate 303, and another set of adjustment components 4 is located on the top of the bottom plate 301. The third set of adjustment components 4 can adjust the left and right movement of the contact plate 305.

[0037] Working principle: The operator moves the positioning column 310 upwards, disengaging it from the limiting block 308 and releasing the restriction on the base plate 301. Then, the operator rotates the limiting plate 309 forward, disengaging it from the limiting block 308. Next, the operator moves the base plate 301 to the left. As the base plate 301 moves, the telescopic plate 307 unfolds and rotates to the left, thus supporting the base plate 301 as it moves away from the bottom pressure head of the pressure testing machine 2. During the movement of the base plate 301, its bottom protruding inner wall slides along the support column 3022, ensuring that the base plate 301 can only move left and right. Simultaneously, the hinges on the front and rear sides of the base plate 301... The connecting plate 304 rotates, causing the two sets of L plates 303 to spread out. The inner wall of the bottom of the L plate 303 slides along the guide post 3021, ensuring that the L plate 303 can only move back and forth. At this time, the staff can quickly place the concrete workpiece to be tested on the base plate 301, so that the right side of the workpiece contacts the left side of the contact plate 305. The contact plate 305 plays a role in pre-positioning. Then the base plate 301 is moved to the right. When it moves, the two sets of clamping plates 306 will clamp and fix the workpiece. Then the pressure testing machine 2 is started to perform the test and the test data is recorded.

[0038] For different types of concrete workpieces to be tested, the adjustment components 4 can be used for adaptation. When adjusting the two sets of adjustment components 4 located at the top of the L-plate 303, rotating the threaded rod 402 threaded to the inner wall of the fixing block 401 causes the clamping plate 306 to move as the threaded rod 402 is rotatably connected to the outer wall of the clamping plate 306 on the side closest to the base plate 301. Simultaneously, the extension plate 403 slides along with the clamping plate 306 on the inner wall at the top of the L-plate 303, allowing the clamping plate 306 to have a certain length for easy adjustment. Adjusting the other set of adjustment components 4 located at the top of the base plate 301 can move the contact plate 305 left and right, further adjusting the position of different types of workpieces and ensuring that the workpieces are firmly fixed.

[0039] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
