Technical Field
[0001] The utility model relates to the technical field of concrete specimen demoulding, in particular to a vibration demoulding device suitable for concrete specimens of multiple sizes. Background Art
[0002] A concrete specimen is a test block that is sampled from concrete before its properties are tested. The mold used to make a concrete test block is a square-shaped cavity with four fixed sides. When the concrete test block is made, it needs to be demolded, which is common in construction projects.
[0003] In construction projects, it is found that in the process of forming concrete test blocks, four baffles need to be spliced together, and then concrete is poured in for compression molding. However, the mold cavity composed of the baffles is usually of a single size, and it is easy to be unable to adjust the length of the baffles, which makes it impossible to form concrete test blocks of multiple sizes. At the same time, after the concrete test block solidifies, the concrete test block is easy to adhere to the baffles, making demoulding more difficult. Utility Model Content

[0006] The effect achieved by the above components is: in the process of forming and demolding the concrete specimen, the size of the mold cavity will be single, and the size of the mold cavity cannot be adjusted and limited, and it is convenient to demold the concrete specimen. At this time, the horizontal frame plate can be slid and limited along the side walls of the two vertical frame plates, so that the horizontal frame plate can be moved along the fixed column through the sliding frame at the bottom, so that the position of the horizontal frame plate can be adjusted, and then the positioning frame limited on the surface of the sliding frame is squeezed and fixed by the rotating shaft, so that the size of the mold cavity formed by the entire vertical frame plate and the horizontal frame plate can be adjusted, which is convenient for multi-size demolding.
[0007] Preferably, the positions where the surfaces of the longitudinal frame plate and the transverse frame plate are close to each other are slidably plugged into a limiting frame, the surface of the limiting frame is fixedly connected to a positioning plate, the surface of the transverse frame is provided with a positioning groove corresponding to the position of the positioning plate, and the inner wall of the positioning groove is slidably plugged into the surface of the positioning plate.

[0015] Preferably, the arc surface of the handle is evenly provided with anti-slip patterns.
[0016] In summary, the beneficial effects of the utility model are:
[0017] In the utility model, during the process of forming and demolding the concrete specimen, the size of the mold cavity will be single, and the size of the mold cavity cannot be adjusted and limited, and it is convenient to demold the concrete specimen. At this time, the horizontal frame plate can be slid and limited along the side walls of the two vertical frame plates, so that the horizontal frame plate can be moved along the fixed column through the sliding frame at the bottom, so that the position of the horizontal frame plate can be adjusted, and then the positioning frame limited on the surface of the sliding frame is squeezed and fixed by the rotating shaft. Through the operation of the adjusting device, the size of the mold cavity formed by the entire vertical frame plate and the horizontal frame plate can be adjusted, which is convenient for demolding of multiple sizes.
[0018] In the utility model, when it is necessary to knock and vibrate the longitudinal frame plate to assist demoulding, the handle can be directly turned to drive the elliptical block to rotate. When the short axis of the elliptical block moves in a direction parallel to the middle axis of the slide bar, the spring will give a pulling force to the connecting plate, so that the connecting plate drives the moving rod and the auxiliary block to move toward the longitudinal frame plate. When the short axis of the elliptical block is parallel to the middle axis of the slide bar, the pressure ball is separated from the elliptical block, and the tension of the spring will directly drive the auxiliary block to knock on the longitudinal frame plate, and a knock is completed. As the handle continues to be turned to drive the elliptical block to rotate, the long axis of the elliptical block will move in a direction parallel to the middle axis of the slide bar. At this time, the elliptical block will spread the two pressure balls away from each other, and the two auxiliary blocks will be separated from the surfaces of the two longitudinal frame plates respectively. In this way, it can be achieved that the two longitudinal frame plates can be repeatedly knocked and vibrated by rotating the handle with one hand, thereby assisting the demoulding effect.

[0029] Detailed description of usage: When adjusting and limiting the size of the mold cavity of the concrete specimen, first install and fix the two longitudinal frame plates 2 to the upper surface of the bottom plate 1, then pull the two transverse frame plates 3, and let the sliding frame 402 at the bottom end of the transverse frame plate 3 slide and limit along the fixed column 401 on the surface of the bottom plate 1, and at the same time, the positioning frame 403 on the arc surface of the fixed column 401 is moved and limited along the slide groove 404 on the side wall of the sliding frame 402, so that the moving position of the entire transverse frame plate 3 cannot be offset. After reaching the specified position, rotate the rotating shaft 408 on the surface of the fixed column 401 to allow the rotating shaft 408 to position The frame 403 is squeezed and fixed, at this time, the position of the entire transverse frame plate 3 cannot be moved, and a concrete specimen cavity is formed between the two longitudinal frame plates 2 and the two transverse frame plates 3.

[0030] When it is necessary to knock and vibrate the longitudinal frame plate 2 to assist in demoulding, the handle 510 can be directly turned to make the handle 510 drive the elliptical block 509 to rotate. When the short axis of the elliptical block 509 moves in a direction parallel to the central axis of the slide bar 505, the spring 503 will give a pulling force to the connecting plate 504, so that the connecting plate 504 drives the moving rod 502 and the auxiliary block 507 to move toward the longitudinal frame plate 2. When the short axis of the elliptical block 509 is parallel to the central axis of the slide bar 505, the pressing ball 511 is separated from the elliptical block 509, and the pulling force of the spring 503 will directly drive the auxiliary block 507 to knock on the longitudinal frame plate 2, and one knocking is completed.

At this time, the elliptical block 509 will push the two pressure balls 511 away from each other, and the two auxiliary blocks 507 will separate from the surfaces of the two longitudinal frame plates 2 respectively. This can be achieved by repeatedly rotating the handle 510 with one hand to repeatedly knock and vibrate the two longitudinal frame plates 2, thereby assisting in the demoulding effect.
