A self-curing, non-removable formwork for the main structure of a building

Abstract

This utility model relates to a self-curing, non-removable formwork for building structures, comprising a formwork body with an installation part and a connecting part formed at both ends for sequentially connecting multiple sets of formwork bodies. The installation part and the connecting part are interlocked. Shear keys are connected to the end face of the formwork body, and multiple shear keys enclose a casting space. By setting connecting parts and installation parts at both ends of the formwork body, rapid installation between multiple sets of formwork bodies is achieved through a splicing structure. At the same time, by setting shear keys on the formwork body, the shear keys can strengthen the connection between two sets of formwork bodies to improve the connection strength, and can also increase the contact area between the formwork and the concrete structure to improve the resistance to detachment of the formwork body, making the concrete inside the formwork less susceptible to cracking or formwork detachment caused by extreme environmental factors such as temperature and humidity.

Description

Technical Field

[0001] This utility model belongs to the field of non-removable formwork, specifically designing a self-curing non-removable formwork for the main body of building structures. Background Technology

[0002] With the rapid development of industrialized construction and rapid construction technologies, formwork engineering is no longer limited to traditional temporary support systems but focuses more on integrated formwork structures. In traditional construction, formwork only serves as temporary support for concrete pouring, and needs to be removed and discarded after hardening, leading to material waste, extended construction periods, and secondary pollution. Furthermore, existing self-curing formwork has poor linear splicing and low shear strength and anti-detachment strength after concrete curing. Therefore, there is an urgent need for a self-curing, non-removable formwork that is easy to install, reliably connected, and tightly bonded to the concrete matrix. Utility Model Content

[0003] In order to solve the above-mentioned problems in the existing technology, the purpose of this utility model is to provide a self-curing, non-removable template for the main body of building structures.

[0004] The technical solution adopted by this utility model is as follows: it includes a template body, with an installation part and a connecting part formed at both ends for connecting multiple sets of template bodies end to end in sequence, the installation part and the connecting part being inserted into each other; a shear key is connected to the end face of the template body, and multiple shear keys enclose a pouring space, a shear plate is provided in the pouring space, and through holes are opened in the shear keys and shear plates, the through holes being used to form a concrete column embedded between the shear key or shear plate and the concrete matrix after the concrete has cured.

[0005] As a preferred embodiment of the present invention, the mounting portion is a connecting plate protruding outward along the end of the template body, and the connecting portion is a connecting groove recessed inward along the end of the template body. The connecting plate and the connecting groove are inserted into each other, and the connecting plate and the connecting groove are located at opposite ends of the template body.

[0006] As a preferred embodiment of this utility model, the shear key is provided with a connecting hole, which is used for reinforcing connection between the two sets of template bodies.

[0007] As a preferred embodiment of this utility model, the connecting hole on one of the shear keys on the template body is a circular through hole, and the connecting hole on the other shear key is a threaded hole.

[0008] As a preferred embodiment of this utility model, the shear plate is provided in multiple sets, and the multiple sets of shear plates are evenly distributed in the casting space.

[0009] As a preferred embodiment of this utility model, the through holes are provided in multiple sets, and the multiple sets of through holes are distributed along the height direction of the shear key or shear plate.

[0010] As a preferred embodiment of this utility model, the template body is made of steel selected from stainless steel, aluminum alloy, and galvanized steel.

[0011] As a preferred embodiment of this invention, a coating layer is formed on one end of the template body near the shear key.

[0012] As a preferred embodiment of the present invention, the coating layer is made of one of epoxy resin, polyurethane or fluorocarbon.

[0013] The beneficial effects of this utility model are as follows: By setting connecting parts and installation parts at both ends of the main body of the template, the rapid installation of multiple sets of template bodies can be achieved through the splicing structure. At the same time, by setting shear keys on the main body of the template, the shear keys can strengthen the connection between two sets of template bodies to improve the connection strength. On the other hand, they can increase the contact area between the template and the concrete structure to improve the resistance to detachment of the template body. This makes the concrete inside the template less susceptible to cracking or detachment caused by extreme environmental factors such as temperature and humidity.

[0014] By creating through holes in the shear keys and shear plates, concrete slurry can flow into the through holes when concrete is poured into the pouring space. After the concrete solidifies, it forms a concrete column that penetrates the shear keys or shear plates and is embedded between the formwork body and the concrete matrix, thereby improving the shear strength and anti-falling strength of the formwork body.

[0015] By setting a rust-resistant structure for the main body of the template, stainless steel, aluminum alloy, and galvanized steel can be used as the template material. Epoxy resin, polyurethane, and fluorocarbon coatings can be applied to the template surface, allowing the template to be directly used in the main structure of building projects, increasing the overall service life and stability of the structure.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only for explaining the present utility model and are not intended to limit the present utility model; that is, the described embodiments are only some embodiments of the present utility model, and not all embodiments. The components of the embodiments of the present utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0020] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0021] The following is combined with Figure 1-3 This invention describes a self-curing, non-removable formwork for building structures, comprising a formwork body 1 for temporary support during concrete pouring. Both ends of the formwork body 1 have installation and connecting parts for sequentially connecting multiple sets of formwork bodies 1. The installation and connecting parts are interlocked, enabling rapid sequential assembly of two sets of formwork bodies 1. Shear keys 2 are connected to the end faces of the formwork body 1, and multiple shear keys 2 enclose a pouring space 13. Shear plates 3 are provided within the pouring space 13. Shear keys 2 and shear plates 3 are used to enhance the mechanical interlocking force between the formwork and the concrete. Through holes 22 are provided on the shear keys 2 and shear plates 3. The through holes 22 are used to form a concrete column that is embedded between the shear keys 2 or shear plates 3 and the concrete matrix after the concrete has cured. When pouring concrete into the pouring space 13, the concrete slurry can flow into the through holes 22. After the concrete in the through holes 22 has cured, it forms a concrete column that penetrates the shear keys 2 or shear plates 3 and is embedded between the formwork body 1 and the concrete matrix, thereby improving the shear strength and anti-detachment strength of the formwork body 1.

[0022] The shear plate 3 and shear key 2 are designed to prevent cracking. Because the thermal deformation coefficients of steel bars and concrete are different, and the internal and external temperatures and humidity levels vary, the formwork is prone to detachment and the structure may crack, leading to a decrease in the structure's load-bearing capacity and stability. In this application, multiple shear keys 2 and shear plates 3 are placed inside the formwork body 1, and through holes 22 are made in the shear plates 3 and shear keys 2 to increase friction and adhesion, thus resisting the effects of temperature and humidity.

[0023] In this embodiment, please refer to Figure 3. The mounting part is a connecting plate 11 that protrudes outward from the end of the template body 1, and the connecting part is a connecting groove 12 that is recessed inward from the end of the template body 1. The connecting plate 11 and the connecting groove 12 are inserted into each other, and the connecting plate 11 and the connecting groove 12 are located at opposite ends of the template body 1. When connecting the template bodies 1, the end of the first template body 1 with the connecting plate 11 is inserted into the connecting groove 12 of the second template body 1. In this way, multiple template bodies 1 can be connected sequentially, realizing the linear splicing of multiple template bodies 1.

[0024] Further, please refer to Figure 1 As shown, the shear key 2 has a connecting hole 21, which is used to reinforce the connection between two sets of template bodies 1. In the linear splicing of multiple templates, in order to improve the stability of the connection of the connecting plate 11 in the connecting groove 12, the connecting hole 21 is opened on the shear key 2. The connecting hole 21 can be used to reinforce the connection between two adjacent sets of template bodies 1 by bolts or pins, so as to improve the strength of the splicing node. It should be noted that in order to avoid fluid leakage at the gaps, a waterproof coating can be applied to the gaps after the construction of multiple template bodies 1 is completed, so as to prevent internal and external fluids from seeping through the gaps.

[0025] In this embodiment, please refer to Figure 3 As shown, the connecting hole 21 on one of the shear keys 2 on the template body 1 is a circular through hole 211, and the connecting hole 21 on the other shear key 2 is a threaded hole 212. To reduce the complexity of the connection between the template bodies 1, one of the two connecting shear keys 2 has a circular through hole 211, and the other has a threaded hole 212 that matches the through hole. Bolts can pass through the circular through hole 211 and be threaded into the threaded hole 212 to strengthen the splicing between the two sets of template bodies 1. In this embodiment, the connecting plate 11 and the connecting groove 12 are formed on one of the opposite sides of the template body 1, that is, the left and right ends when the template body 1 is installed. At the same time, the connecting plate 11 and the connecting groove 12 can be formed at the upper and lower ends of the template body 1 respectively according to the needs of the upper and lower connection, so as to splice the upper and lower parts of the template body 1.

[0026] This embodiment is preferred; please refer to [the specific example]. Figures 2-3 As shown, the shear plate 3 is provided in multiple sets, and the multiple sets of shear plates 3 are evenly distributed in the pouring space 13. In this embodiment, the end face of the template body 1 is provided with five sets. The even distribution of multiple sets of shear plates 3 on the end face of the template body 1 can optimize stress distribution and enhance the overall integrity, improve the support strength of the template without disassembly for the poured wall, and prevent the template body 1 from falling off after being connected as a whole.

[0027] In a further embodiment, please refer to Figure 3 As shown, multiple sets of through holes 22 are provided, and these multiple sets of through holes 22 are distributed along the height direction of the shear key 2 or the shear plate 3. The multiple sets of through holes 22 form a multi-layer interlocking structure to improve shear strength.

[0028] In this embodiment, please refer to Figure 1 As shown, the template body 1 is made of stainless steel, aluminum alloy, or galvanized steel, giving the template body 1 high strength and corrosion resistance.

[0029] In some embodiments, please refer to Figure 1 As shown, a coating layer is formed at one end of the template body 1 near the shear key 2. The coating layer is used to improve the corrosion resistance and bonding strength of the template body 1 at the end in contact with the concrete.

[0030] For more details, please refer to Figure 1 As shown, the coating is made of one of epoxy resin, polyurethane or fluorocarbon.

[0031] Working principle of this utility model: Insert one end of the first template body 1 with the connecting plate 11 into the connecting groove 12 of the adjacent second template body 1, ensuring that the first and second template bodies 1 are on the same horizontal line. Simultaneously pass the fixing bolt through the circular through hole 211 on the first template body 1 and the threaded hole 212 on the second template body 1. Rotate the bolt to engage with the threaded hole 212, thus achieving mutual locking between the first and second template bodies 1 via the two shear keys 2, thereby improving the connection strength. Similarly, multiple template bodies 1 can be connected vertically in the same manner according to actual needs. After the template installation is completed, reinforcing steel bars can be installed inside the casting space formed between the multiple shear keys 2. After the concrete is poured, the formwork body 1 and the concrete wall form an integral structure after solidification, and the formwork is directly used as part of the construction structure, eliminating the need to dismantle the formwork body 1. In the connection between the formwork body 1 and the wall, shear keys 2 and shear plates 3 are provided on the side of the formwork body 1 near the wall to be poured. Through holes 22 are provided on the shear keys 2 and shear plates 3. When concrete is poured into the pouring space 13, the concrete slurry can flow into the through holes 22. After the concrete in the through holes 22 solidifies, it forms a concrete column that penetrates the shear keys 2 or shear plates 3 and is embedded between the formwork body 1 and the concrete matrix, thereby improving the shear strength and anti-detachment strength of the formwork body 1 and increasing the connection strength of the formwork body 1 on the building wall.

[0032] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0033] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
