Technical Field
[0001] This utility model relates to the field of concrete technology, and in particular to crack-resistant concrete structural components. Background Technology
[0002] Concrete structure, also known as concrete structure, is an engineering structure built with concrete as the main material. It is usually combined with steel bars to form a reinforced concrete structure, while plain concrete refers to a concrete structure without reinforcement or without load-bearing steel bars.
[0003] Concrete structural members are molded components in which concrete is poured inside the structure. After the concrete structure is formed, the member is removed from the structure. When demolding existing members, the demolding process is complicated due to the good bonding properties of concrete, and it is very easy to cause cracking or even damage to the concrete structure, which ultimately affects its subsequent use.
[0004] Therefore, we propose crack-resistant concrete structural components to solve the above problems. Utility Model Content
[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a crack-resistant concrete structural component.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:

A bottom plate is slidably mounted at the bottom notch of the main body. A base is installed at the bottom of the main body, and there is a gap between the base and the main body. A pry bar mechanism is matched between the base and the main body.

[0009] Preferably, a first telescopic column is connected between the middle of the base and the middle of the bottom plate, and a plurality of second telescopic columns are also connected between the base and the bottom plate, with the plurality of second telescopic columns evenly arranged around the first telescopic column.
[0010] Preferably, the pry bar mechanism includes a rod body, one end of which is fixed with a semi-cylindrical block. The arc-shaped surface of the semi-cylindrical block is used to abut against the upper side of the base. A pry plate is fixed to the semi-cylindrical block, and the pry plate is used to abut against the lower side of the base plate.
[0011] Preferably, the side cross-section of the skid plate is inverted U-shaped, and a U-shaped groove is provided on the upper side of the skid plate, so that the first telescopic column can abut against the U-shaped groove.
[0012] Preferably, two limiting strips are symmetrically provided on each of the four sides of the upper side of the base, and the distance between the two limiting strips is the same as the distance between the two ends of the semi-cylindrical block.
[0013] Preferably, the pushing mechanism includes a push plate, the inner wall of the component body is provided with a groove matching the shape of the push plate, a push rod that slides through the component body is fixed on one side of the push plate, a push block is fixed at one end of the push rod, and a limiting block is engaged between the push block and the outer wall of the component body.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] This invention achieves the effect of pushing and molding a concrete structure from the bottom by sliding a base plate at the bottom of the main body of the component.

[0024] 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.
[0025] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0026] Reference Figure 1 , Figure 2 A crack-resistant concrete structural component includes a main body 1, which is rectangular in shape with notches on both the top and bottom. A base plate 2 is slidably mounted at the bottom notch of the main body 1, sealing the bottom of the main body 1. Concrete is poured into the main body 1 for shaping the concrete structure. A base 3 is installed at the bottom of the main body 1, with a gap between the base 3 and the main body 1. A pry bar mechanism is matched between the base 3 and the main body 1. The pry bar mechanism is used to push the base plate 2 upward.
[0027] A pushing mechanism is provided on one side of the main body 1, and a gate mechanism is provided on the other side of the main body 1.
[0028] For the above examples, those skilled in the art should know that when implementing the above technical solutions, the main body 1 of the component is not limited to being set in a rectangular frame shape. Its shape is mainly determined by the shape of the concrete structure to be formed, and the corresponding main body 1 can be made according to the shape of the concrete structure.
[0029] As a technical optimization of this utility model, a first telescopic column 4 is connected between the middle of the base 3 and the middle of the base plate 2. Multiple second telescopic columns 5 are also connected between the base 3 and the base plate 2, and these multiple second telescopic columns 5 are evenly arranged around the first telescopic column 4. The first telescopic column 4 and the multiple second telescopic columns 5 serve to stabilize the base plate 2, providing stable vertical lifting and lowering control for the base plate 2.
[0030] Reference Figure 3 , Figure 4 as well as Figure 5The lever mechanism includes a lever body 6, with a semi-cylindrical block 7 fixed to one end of the lever body 6. The arc-shaped surface of the semi-cylindrical block 7 is used to abut against the upper side of the base 3. A pry plate 8 is fixed to the semi-cylindrical block 7, and the pry plate 8 is used to abut against the lower side of the base plate 2. The structure formed by the lever body 6, the semi-cylindrical block 7, and the pry plate 8 realizes the pushing operation of the base plate 2 through the lever principle. That is, the semi-cylindrical block 7 abuts against the base plate 2 as a fulcrum. By pressing down the end of the lever body 6 away from the semi-cylindrical block 7, the pry plate 8 can push the base plate 2 upward and move.
[0031] As a technical optimization of this utility model, the side cross-section of the pry bar 8 is inverted U-shaped, and a U-shaped groove 11 is provided on the upper side of the pry bar 8, into which the first telescopic column 4 can abut. The first telescopic column 4, in conjunction with the U-shaped groove 11, serves to position the pry bar 8.
[0032] As a technical optimization of this utility model, two limiting strips 9 are symmetrically provided on all four sides of the upper side of the base 3, and the distance between the two limiting strips 9 is the same as the distance between the two ends of the semi-cylindrical block 7. When the semi-cylindrical block 7 abuts against the upper side of the base 3, it can be positioned and restricted by the two limiting strips 9. The semi-cylindrical block 7 can slide on the upper side of the base 3, and its two ends are effectively restricted by the corresponding two limiting strips 9, so that there will be no displacement.
[0033] As a technical optimization of this utility model, the pushing mechanism includes a push plate 10. The inner wall of the component body 1 is provided with a groove that matches the shape of the push plate 10. A push rod 12 that slides through the component body 1 is fixed to one side of the push plate 10. A push block 13 is fixed to one end of the push rod 12. A limiting block 14 is engaged between the push block 13 and the outer wall of the component body 1. By removing the limiting block 14, the push rod 12 and the push plate 10 can be moved by pushing the push block 13.
[0034] As a technical optimization of this utility model, the gate mechanism includes a closing plate 15. The main body 1 of the component has a side opening corresponding to the closing plate 15. Both sides of the side opening are provided with sliding grooves, and the two sides of the closing plate 15 are slidably connected to the two sliding grooves respectively. The closing plate 15 is used to close and open the side opening.
[0035] In this invention, the working principle of the device is as follows:
[0036] This device can be used as a mold for concrete test blocks or as a normal concrete mold, i.e., as a concrete structure forming component. Before use, ensure that the sealing plate 15 closes the side opening, the push plate 10 is located in the groove on the inner wall of the component body 1, and the push block 13 is engaged with the outer wall of the component body 1 by a limiting block 14. The base plate 2 is set at the bottom of the component body 1 and will be used for the concrete structure forming component later. Then, the concrete structure is formed inside the component body 1. When demolding is required, the demolding operation can be performed using a pry bar mechanism. That is, the worker holds the rod 6 and inserts the pry plate 8 between the base 3 and the component body 1. The first telescopic column 4, in conjunction with the U-shaped groove 11, positions the pry plate 8. At the same time, the arc surface of the semi-cylindrical block 7 can slide on the upper side of the base 3 and is effectively restricted at both ends by the corresponding two limiting strips 9. Then, using the semi-cylindrical block 7 as a fulcrum against the base plate 2, the pry bar 8 is lifted by pressing down on the end of the rod 6 away from the semi-cylindrical block 7, thus pushing the base plate 2 upward. The rising of the base plate 2 pushes the formed concrete structure, ensuring complete contact between the base plate 2 and the concrete structure. This allows the sides of the concrete structure to better detach from the main component 1, effectively reducing surface damage or even cracking during overall demolding of the concrete structure. Afterward, the sealing plate 15 can be removed, followed by the limiting block 14. By pushing the pusher block 13, the pusher rod 12, along with the pusher plate 10, moves, thereby detaching the concrete structure from the base plate 2 and pushing it out.
[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
