Description

Technical Field

[0001] This utility model relates to the field of slump testing technology, and in particular to a slump testing device for self-compacting concrete. Background Technology

[0002] Slump is a method and indicator for measuring the workability of concrete. On construction sites and in laboratories, slump tests are typically performed to determine the fluidity of the mixture, supplemented by intuitive assessments of cohesiveness and water retention. Slump is a quantitative indicator used to measure the degree of workability and to determine whether construction can proceed normally.

[0003] Referring to the case "A Self-Compacting Concrete Testing Device" (publication number CN218455711U), this utility model discloses a self-compacting concrete testing device, including a testing plate, a slump cone, and a mounting frame. The top surface of the testing plate has a testing area. The mounting frame is fixed to the outer periphery of the testing area. The slump cone is vertically mounted on the mounting frame and positioned directly above the testing area. The testing plate has a clamping mechanism that presses the slump cone firmly onto the testing area. An elastic recovery element is provided between the slump cone and the mounting frame. Lifting legs are located at the four corners of the bottom of the testing plate. This self-compacting concrete testing device has a simple structure, is easy to operate, and can improve measurement accuracy.

[0004] Although the aforementioned slump testing device can raise the slump cylinder vertically, after the slump cylinder rises, personnel still need to measure the slump height of the concrete and the height of the slump cylinder. However, the debugging frame of the aforementioned testing device cannot move the slump cylinder, which can easily cause inconvenience to personnel in recording test data. At the same time, the aforementioned slump testing device cannot adjust the angle of the slump cylinder, so the relatively fixed angle of the slump cylinder will increase the difficulty of cleaning operations to a certain extent. Utility Model Content

[0005] Therefore, it is necessary to provide a self-compacting concrete slump testing device to address the problems of the current slump testing device easily affecting the recording of measurement data by personnel and the inconvenience of cleaning the slump cylinder afterwards.

[0007] A debugging component is disposed on the side of the slump cone body;

[0008] The debugging component includes a connecting rod disposed on the side of the slump cylinder body. Both ends of the connecting rod are provided with collars. The surface of the collar away from the slump cylinder body is fitted with a sleeve, and the surface of the sleeve is provided with positioning holes.

[0009] In one embodiment, the debugging assembly further includes a connecting block fixed to the surface of the slump cylinder body. A movable frame is movably connected to the surface of the connecting block via a rotating shaft. An insertion hole is provided at one end of the connecting rod near the connecting block. An insertion rod is inserted into the movable frame and inserted into the insertion hole.

[0010] In one embodiment, the debugging assembly further includes a fixing seat disposed on the base plate, wherein a vertical rod is inserted into the fixing seat and the vertical rod is inserted into a collar near the slump cylinder body.

[0011] In one embodiment, the surfaces of the collar and the sleeve, which are far from the slump cylinder body, are provided with fixing holes, and a locking rod is inserted between the two fixing holes.

[0012] In one embodiment, a guide rail is fixedly connected to the side of the connecting rod near the connecting block, and the connecting block slides on the surface of the guide rail.

[0013] In one embodiment, a connecting frame is provided on the rear side above, a rotating rod is movably connected in the connecting frame, an adjusting rod is fixedly connected to the surface of the rotating rod, and the adjusting rod is fixedly connected to the sleeve on the side near the sleeve.

[0014] In one embodiment, the surface of the base plate is designed to be open, a filling pad is provided below the base plate and at the opening, and push rods are fixedly connected to the four corners of the bottom of the base plate.

[0015] Beneficial effects

[0016] 1. By adjusting the guide rail of the component, after the slump cone body is vertically lifted by the personnel, the slump cone body can be moved to the side, which helps the personnel to measure and compare the height of the concrete pile and the height of the slump cone body. This can effectively ensure the accuracy of the test data and also provide some convenience for the personnel.

[0030] The following is combined Figures 1-4 This invention describes a slump testing device for self-compacting concrete.

[0031] In one embodiment, a self-compacting concrete slump testing device includes: a base plate 1 and a slump cylinder body 2 disposed thereon;

[0032] Debugging component 5 is located on the side of the slump cylinder body 2;

[0033] like Figure 1 , Figure 3 and Figure 4 As shown, the debugging component 5 includes a connecting rod 501 disposed on the side of the slump cylinder body 2. Both ends of the connecting rod 501 are provided with collars 502. A sleeve 506 is sleeved on the surface of the collar 502 away from the slump cylinder body 2. A positioning hole is opened on the surface of the sleeve 506. Fixing holes are opened on the surfaces of the collar 502 and the sleeve 506 away from the slump cylinder body 2. A locking rod is inserted between the two fixing holes.

[0034] The debugging assembly 5 also includes a connecting block 504 fixed to the surface of the slump cylinder body 2. A movable frame 507 is movably connected to the surface of the connecting block 504 via a rotating shaft. A mounting hole is provided at one end of the connecting rod 501 near the connecting block 504. A rod is inserted into the movable frame 507 and inserted into the mounting hole. The debugging assembly 5 also includes a fixed seat set on the base plate 1. A vertical rod 505 is inserted into the fixed seat and inserted into the collar 502 near the slump cylinder body 2. A guide rail 503 is fixedly connected to the side of the connecting rod 501 near the connecting block 504. The connecting block 504 slides on the surface of the guide rail 503.

[0035] A connecting frame is provided on the rear side above, and a rotating rod 4 is movably connected in the connecting frame. An adjusting rod 3 is fixedly connected to the surface of the rotating rod 4, and the side of the adjusting rod 3 near the sleeve 506 is fixedly connected to the sleeve 506.

[0036] When concrete slump testing is required, first remove the locking rods from sleeve 506 and collar 502, allowing sleeve 506 to function as a bearing in connecting rod 501. Then, insert vertical rod 505 through another collar 502 into a fixed seat. At this point, concrete can be filled into the slump cylinder body 2. After preparation, adjust the rotating rod 4 using the handle. The rotating rod 4, through the adjusting rod 3, engages with sleeve 506 to connect connecting rod 501 and connecting block 504, thus securing the slump cylinder body. 2. The vertical rod 505 is raised vertically. After it rises to a certain height, the insert rod in the movable frame 507 is pulled out and the movable frame 507 is moved to one side of the connecting block 504 so that the connecting block 504 is disengaged from the connecting rod 501. At this time, the workers can use the two connecting blocks 504 in conjunction with the guide rail 503 to move the position of the slump cylinder body 2. Then the workers reverse the adjustment of the rotating rod 4, and the slump cylinder body 2 will fall on the bottom plate 1. At this time, the workers can measure and compare the height of the slump cylinder body 2 and the concrete pile.

[0037] If the slump cylinder body 2 needs to be cleaned later, simply insert the locking rod into the fixing holes of the collar 502 and the sleeve 506, then remove the vertical rod 505 from the fixing seat. Then, the four push rods 6 will lift the bottom plate 1 and the slump cylinder body 2. Personnel can adjust the angle of the slump cylinder body 2 by adjusting the rotating rod 4 so that the opening of the slump cylinder body 2 faces forward, so that personnel can clean it.

[0038] The surface of the base plate 1 is designed with an opening. A filling pad is provided below the base plate 1 and at the opening. Push rods 6 are fixedly connected to the four corners of the bottom of the base plate 1.

[0039] When personnel conduct concrete slump tests, the four push rods 6 need to move the bottom plate 1 downward so that the bottom of the bottom plate 1 is in contact with the filling pad. At this time, the filling pad will fill the opening of the bottom plate 1, so that the bottom plate 1 forms a complete plate. At the same time, it can also keep the bottom of the slump cylinder body 2 in contact with the bottom plate 1 when it is not moving, to prevent concrete from leaking out.

[0040] When subsequent personnel need to clean the slump cylinder body 2, the push rod 6 needs to drive the bottom plate 1 and the slump cylinder body 2 above it to rise, so that there is a certain height between the lower opening of the slump cylinder body 2 and the filling pad. In this way, the movement path interference between the lower part of the slump cylinder body 2 and the filling pad can be avoided when the slump cylinder body 2 is rotated.

[0041] When conducting slump tests on self-compacting concrete, first ensure that the testing tools, such as the slump cylinder body 2, steel ruler, vibrator, etc., are prepared and that the slump cylinder body 2 is clean and free of debris. Then, select a suitable concrete sample and place the slump cylinder body 2 vertically on the base plate 1. Next, divide the concrete sample evenly into three layers, each layer being approximately one-third of the height of the slump cylinder body 2. When filling each layer, use an iron rod or vibrator to lightly compact the concrete. After filling the last layer and leveling it, quickly and vertically lift the slump cylinder body 2, allowing the concrete to slump freely. Use a steel ruler to measure the vertical distance from the top of the original concrete to the surface of the collapsed concrete; this distance is the slump value.

[0042] If one side of a concrete specimen collapses or one side fails in shear, it should be resampled and tested again. If the same situation occurs again on the second test, it indicates that the workability of the concrete is poor and should be recorded.

[0043] Working principle: When concrete slump testing is required, first remove the locking rod to allow the sleeve 506 to rotate on the surface of the collar 502, and insert the vertical rod 505 into the fixed seat. Then, fill the slump cylinder body 2 with concrete. After preparation, adjust the rotating rod 4. The rotating rod 4, through the adjusting rod 3, cooperates with the sleeve 506 to vertically raise the connecting rod 501 and the connecting block 504 of the slump cylinder body 2. After it rises to a certain height, loosen the movable frame 507 in the movable frame 507, so that the connecting block 504 is disengaged from the connecting rod 501. At this time, the worker can then fill the slump cylinder body 2 with concrete. The position of the slump cone body 2 is moved, and then the rotating rod 4 is adjusted in the opposite direction. The slump cone body 2 will fall onto the base plate 1. At this time, personnel can measure and compare the height of the slump cone body 2 and the concrete pile. If the slump cone body 2 needs to be cleaned later, simply reinsert the locking rod into the fixing holes of the collar 502 and the sleeve 506, and then remove the vertical rod 505 from the fixing seat. Then, the four push rods 6 will lift the base plate 1 and the slump cone body 2. Personnel can adjust the angle of the slump cone body 2 by adjusting the rotating rod 4 so that the opening of the slump cone body 2 faces forward, so that personnel can clean it.

[0044] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0045] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
