Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and to a building template with controllable deformation. Background Technology

[0002] In construction projects, formwork technology has a significant impact on the quality, cost, and efficiency of the project. Simultaneously, with the increasing prominence of environmental issues, green, low-carbon, and sustainable concepts are being promoted in construction. Plastic formwork has advantages such as light weight, easy assembly and disassembly, and high reusability, and its use is pollution-free, waste-free, noise-free, and dust-free. However, plastic formwork has a large coefficient of thermal expansion and contraction, making it highly susceptible to temperature fluctuations. At high temperatures, a 3m long board can expand or contract by 3-4mm. If formwork is laid at night, arching will occur in the middle of the formwork by noon; if it is laid at noon, the formwork will shrink by evening, creating gaps of 3-4mm between adjacent boards. Furthermore, the heat of hydration from large volumes of concrete can also cause formwork deformation. This affects construction and reduces the lifespan of the formwork. Utility Model Content

[0003] To address the technical problems in the prior art, this utility model provides a deformable and controllable building template, including template units and elastic connectors. Elastic connectors are installed between two adjacent template units and are connected into a whole through the elastic connectors.

[0004] Furthermore, the template unit has a first protrusion on one side and a first groove on the other side, and the first protrusion engages with the first groove of the adjacent template unit.

[0005] Furthermore, the elastic connector includes a first elastic body and a second elastic body, wherein the sides of the first elastic body and the second elastic body that are far apart from each other are respectively connected to two adjacent template units, and the sides that are close to each other are tightly fitted together.

[0006] Furthermore, the template unit is provided with a T-shaped slot, and both the first elastic body and the second elastic body are provided with T-shaped protrusions that cooperate with the T-shaped slot. The T-shaped protrusions and the T-shaped slot are detachably connected.

[0007] Furthermore, the first elastic body and the second elastic body are respectively provided with a second groove and a second protrusion on the side away from the T-shaped protrusion, and the first elastic body and the second elastic body are tightly fitted together through the second groove and the second protrusion.

[0008] Furthermore, the template unit includes a basic unit, an inside corner unit, and an outside corner unit, which can be freely combined and assembled.

[0009] Furthermore, the basic unit, the inside corner unit, and the outside corner unit are all hollow structures.

[0010] Beneficial effects: 1. In this utility model, the elastic connector allows the formwork to freely shrink and contract with temperature changes, satisfying concrete formwork support and pouring at any time, avoiding grout leakage or warping, improving the service life of the formwork, and ensuring construction quality and efficiency. Specifically, when the formwork unit expands due to heat, it squeezes the elastic connector, causing the elastic connector to be in a contracted state. When the formwork unit shrinks due to cold, it pulls the elastic connector.

[0011] 2. In this utility model, the longitudinal displacement of two adjacent template units can be restricted by the setting of the first protrusion and the first groove, while ensuring that the two adjacent template units are tightly connected.

[0012] 3. In this utility model, the setting of the first elastic body and the second elastic body can improve the shrinkage range of the template and further ensure that there will be no leakage or warping. The setting of the T-shaped slot and the T-shaped protrusion can facilitate the replacement of the first elastic body and the second elastic body, and at the same time facilitate the installation and positioning of the first elastic body, the second elastic body and the template unit. The combination of the setting of the second groove and the second protrusion can ensure that the first elastic body and the second elastic body are connected more tightly and prevent them from separating due to deformation.

[0013] 4. The design of this utility model, which allows for free combination and assembly of basic units, internal corner units, and external corner units, can be applied to any construction scenario; and the hollow structure of the basic units, internal corner units, and external corner units reduces the weight of the template.

[0023] This utility model provides a building template with controllable deformation, such as Figure 1 As shown, it includes a template unit 1 and an elastic connector 2. An elastic connector 2 is installed between two adjacent template units 1 and they are connected into one unit through the elastic connector 2.

[0024] In this embodiment, the elastic connector 2 allows the template to freely shrink and contract with temperature changes, satisfying concrete formwork support and pouring at any time, avoiding grout leakage or warping, improving the service life of the template, and ensuring construction quality and efficiency. Specifically, when the template unit 1 expands due to heat, it squeezes the elastic connector 2, causing the elastic connector 2 to be in a contracted state. When the template unit 1 shrinks due to cold, it pulls the elastic connector.

[0025] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the template unit 1 has a first protrusion 3 on one side and a first groove 4 on the other side. The first protrusion 3 cooperates with the first groove 4 of the adjacent template unit 1. When they cooperate, the elastic connector 2 will deform and extend into the first groove 4 synchronously with the first protrusion 3.

[0026] In this embodiment, the longitudinal displacement of two adjacent template units 1 can be restricted by the first protrusion 3 and the first groove 4, while ensuring that the two adjacent template units 1 are tightly connected.

[0027] In this utility model, preferably, such as Figure 1 and Figure 2As shown, the elastic connector 2 includes a first elastic body 21 and a second elastic body 22. The sides of the first elastic body 21 and the second elastic body 22 that are far apart from each other are respectively connected to two adjacent template units 1, and the sides that are close to each other are tightly fitted together.

[0028] In this embodiment, by setting the first elastic body 21 and the second elastic body 22, the shrinkage range of the template can be increased, further ensuring that there will be no leakage or warping.

[0029] In this utility model, preferably, such as Figure 1 and Figure 2 As shown, the template unit 1 is provided with a T-shaped slot 5, and the first elastic body 21 and the second elastic body 22 are each provided with a T-shaped protrusion 6 that cooperates with the T-shaped slot 5. The T-shaped protrusion 6 is detachably connected to the T-shaped slot 5. The first elastic body 21 and the second elastic body 22 are respectively provided with a second groove and a second protrusion on the side away from the T-shaped protrusion 6. The first elastic body 21 and the second elastic body 22 are tightly fitted together through the second groove and the second protrusion.

[0030] In this embodiment, the T-shaped slot 5 and the T-shaped protrusion facilitate the replacement of the first elastic body 21 and the second elastic body 22, and also facilitate the installation and positioning of the first elastic body 21, the second elastic body 22 and the template unit 1. Combined with the second groove and the second protrusion, the connection between the first elastic body 21 and the second elastic body 22 is made tighter, preventing them from separating due to deformation.

[0031] In this utility model, preferably, such as Figure 1 , Figure 3 and Figure 4 As shown, the template unit 1 includes a basic unit 11, an inside corner unit 12, and an outside corner unit 13. The basic unit 11, the inside corner unit 12, and the outside corner unit 13 can be freely combined and assembled. Specifically, when there is a corner, either the inside corner unit 12 or the outside corner unit 13 can be used to ensure that the corner position is not easily deformed. The basic unit 11, the inside corner unit 12, and the outside corner unit 13 are all hollow structures.

[0032] In this embodiment, the free combination and assembly of the basic unit 11, the inside corner unit 12, and the outside corner unit 13 can be applied to any construction scenario; the hollow structure of the basic unit 11, the inside corner unit 12, and the outside corner unit 13 can reduce the weight of the template.

[0033] 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.

[0034] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
