[0027] In view of the foregoing, the prior art conventional formwork fixing device adopts a method of fixing the formwork on the outside of the wall body by penetrating the pull rod through the inside of the structure, which leads to the problem of secondary processing of the position of the screw rod after the formwork is removed. The present application provides a wall body formwork fixing device.

[0028] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0029] In this embodiment, a wall body formwork fixing device is disclosed, Figure 1 The entire three-dimensional structure of the wall body formwork fixing device is shown.

[0030] At present, the wall body formwork fixing technology for cast-in-place box culvert and passageway in China still widely adopts a relatively traditional method: the pull rod is penetrated through the inside of the structure to serve as a support point, thereby firmly fixing the formwork on the outside of the wall body. After the formwork is removed, the position of the pull rod needs to be processed. Moreover, this traditional fixing method also brings high construction cost, which not only requires high technical level of construction personnel to cope with complicated procedures and complex operations, but also consumes a large amount of labor and material resources.

[0031] Please refer to Figure 1The utility model discloses a wall formwork fixing device, which comprises an inner support assembly 1 and an outer support assembly 2, wherein the inner support assembly 1 is arranged between the inner sides of the two rows of wall formworks, and the inner support assembly 1 provides outward support force for the two rows of wall formworks; the outer support assembly 2 is arranged on the outer sides of the two rows of wall formworks, and the outer support assembly 2 provides inward support force for the two rows of wall formworks.

[0032] Further, the inner support assembly 1 comprises an inner support frame and side drags 3, wherein the side drags 3 are arranged on both sides of the inner support frame; one end of each side drag 3 is fixed to the inner support frame, and the other end is fixed to the wall formwork. The inner support frame comprises a plurality of support frames and connecting rods for connecting the support frames, wherein the support frames comprise horizontal rods and vertical rods arranged in parallel with each other, the horizontal rods and the vertical rods are connected to each other in a cross manner, and the plurality of support frames are fixed by the connecting rods. This cross connection mode greatly enhances the strength and stability of the inner support frame, so that it can withstand a larger load. The plurality of support frames are fixed by the connecting rods to form an integral support system, further improving the support effect.

[0033] Further, a plurality of support points 4 are arranged on the outer sides of the wall formworks; one end of the outer support assembly 2 is arranged on a fixed surface, and the other end is arranged below the lower end of the support point 4. According to the height of the wall, one end of the outer support assembly 2 can be arranged at different support points to ensure the stability of the whole formwork. The cooperation of the outer support assembly 2 and the inner support assembly 1 not only provides stable support force, but also can adapt to the slight deformation of the wall formwork during the pouring process to some extent, thereby ensuring the stability of the formwork and the forming quality of the wall.

[0034] Further, the number of the outer support assemblies 2 arranged on the outer sides of each wall formwork is at least two. More than two outer support assemblies 2 ensure that the wall can remain stable when subjected to external force and will not deform or be damaged due to uneven stress.

[0035] Further, the angle between the outer support assembly 2 and the ground is 45°-60°. The inclination range of 45°-60° enables the outer support assembly 2 to better withstand the force from the wall formwork and effectively transmit it to the fixed surface. The inclination range of 45°-60° also enables the outer support assembly 2 to produce a certain self-locking effect when subjected to external force, improving stability and anti-overturning ability.

[0036] Further, the fixed surface is the ground or the building side surface. The outer support assembly 2 can be flexibly fixed by external structures and surrounding environment, and the fixing method is various. In principle, it is firm enough, and various choices enable the outer support assembly 2 to flexibly adapt to different construction environments and conditions, whether on the ground or on the surface, to provide stable flexibility. This greatly improves construction efficiency and the universality of the formwork.

[0037] Further, the outer support assembly 2 is made of a steel pipe. The steel pipe has the advantages of high strength, light weight, good corrosion resistance, etc., and can meet various requirements of the outer support assembly 2 during construction. The steel pipe is also easy to process and connect, making the manufacturing and installation process more convenient and fast. The length of the steel pipe can be combined at will according to the actual situation. It can also be composed of better materials, or even fixed modulus disc buckles.

[0038] Further, the side drag 3 is a telescopic side drag 3. The lateral end of the inner support assembly 1 is a telescopic side drag 3, which can adjust the lateral size of the inner support assembly 1 according to the distance between different wall bodies. The inner support assembly 1 can be flexibly adjusted according to the width of the wall formwork to ensure the close fit and stable support between the inner formworks, and can also adapt to the changing needs of the wall formwork at different construction stages, improving the applicability of construction.

[0039] Further, the inner support frame is a steel support. The steel support has high strength, good stability, and strong durability, which can meet various requirements of the inner support frame during construction. It is also easy to process and assemble, making the manufacturing and installation process of the inner support frame more convenient and fast. In addition, it can also withstand large loads and deformation, ensuring stability and safety during the process.

[0040] In the description of the embodiments of the present application, it should be noted that the main material of the inner support assembly 1 is not limited to traditional circular steel pipes, disc buckle frames, etc. In principle, the internal main frame meets the good force support.

[0041] In summary, the width of the inner support assembly 1 is adjustable, that is, the inner support assembly 1 can freely adjust the transverse width by the extension and contraction of the side drag 3 and the flexible combination of the main body support, that is, it can satisfy the cast-in-place concrete structure wall of different structural clear width, especially for the box culvert engineering and channel engineering contained in various size and high permeability requirement of various grades of roads and infrastructure, which can be widely applied, more time and labor saving, and the forming effect is good, the quality is more guaranteed. And through the effective combination of the inner support assembly 1 and the outer support assembly 2, a stable and reliable formwork support system is formed, avoiding the use of pull-through screw rods through the inside of the wall in the traditional way to fix the formwork, reducing the damage to the structure itself, and effectively improving the impermeability and waterproof performance of the structure itself.

[0042] It is apparent to those skilled in the art that the present application is not limited to the details of the foregoing exemplary embodiments, and that the present application can be implemented in other particular forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be considered in all respects as illustrative and not restrictive, and the scope of the present application is defined by the appended claims rather than the foregoing description, and it is intended to include all changes falling within the meaning and scope of the equivalent elements of the claims.
