Description

Technical Field

[0001] This utility model belongs to the field of concrete wall structure building technology, specifically relating to a detachable truss support structure that does not require dismantling of formwork. Background Technology

[0002] In concrete and other building structures, on-site reinforcement and formwork are generally required. After pouring concrete, the formwork also needs to be removed. This process is not only time-consuming and labor-intensive, greatly increasing the labor intensity of workers, but also can affect the quality of the building due to external factors. Therefore, using prefabricated, non-removable formwork can help reduce the labor intensity of workers and improve the quality of the building. For example, as shown in CN202021864734.1, it includes an outer panel, a steel frame set between the outer panels, and a wall connection space, with concrete poured between the outer panels. The steel frame includes horizontal and vertical reinforcement. Although it can meet the general usage requirements, it requires steel bars to connect the two together, which is inconvenient for transportation and installation and increases the assembly difficulty for workers. Furthermore, after assembly, during the concrete pouring process, the concrete is in a flowing state and exerts greater lateral pressure on the outer panel, which can easily cause bulging of the formwork. Therefore, a large number of holes need to be drilled and tie rods need to be installed, which also increases the complexity of construction and makes it difficult to meet market demands. Utility Model Content

[0003] The purpose of this utility model is to provide a detachable truss support structure that requires no disassembly and is easy to assemble and disassemble.

[0004] The technical solution to achieve the purpose of this utility model is a detachable truss support for a template that does not need to be disassembled, including a template that does not need to be disassembled and several detachable truss support structures that are set on the side of the template through a connecting structure. The detachable truss support structure includes two lower chords, one upper chord, several web members and several vertical members.

[0005] The two lower chords are arranged in parallel, and the upper chord is parallel to the lower chords, with the upper chord located on the midpoint of the two lower chords;

[0006] The bottom ends of the web members and the vertical members are respectively fixed to the lower chord, and the top ends of the two web members and the top end of the vertical member are fixed at the same position on the vertical member. The two web members and the vertical member are arranged in a "V" shape.

[0007] The web members on the two lower chords are symmetrically arranged with the upper chord as the centerline;

[0008] The lower chord is attached to the side of the non-removable template and fixed by a connecting structure.

[0009] A further preferred embodiment is that the connecting structure includes a connecting steel plate and two tie rods;

[0010] The connecting steel plate is fixed on the non-removable template, and the connecting steel plate is provided with two screw holes symmetrical about the vertical center line;

[0011] The tie rod is connected between the connecting steel plate and the lower chord and locked in place.

[0012] A further preferred embodiment is that the distance between the fixing points of adjacent vertical bars on the upper chord is 200-500mm.

[0013] A further preferred embodiment is that the height between the upper chord and the lower chord is 200-500mm, and the width between the two lower chords is 200-500mm.

[0014] A further preferred embodiment is that the formwork that does not require dismantling includes vertical reinforcement, horizontal reinforcement, and concrete;

[0015] The vertical and horizontal reinforcement bars are arranged in a cross shape, and the concrete covers the vertical and horizontal reinforcement bars.

[0016] A further preferred embodiment is that the surface of the non-removable template is fixed with several handles.

[0017] A further preferred embodiment is that the length of the lower chord is 3300mm, and the length of the upper chord is 2700mm.

[0020] A further preferred embodiment is that the connecting steel plate has a length of 400mm and a width of 100mm.

[0021] This utility model has the following positive effects: Its structure is rationally designed. The detachable truss support structure is fixed to the formwork without needing to be removed via a connecting structure. The detachable truss support structure can be disassembled and assembled from the formwork as needed, facilitating transportation. Furthermore, the connecting structure reduces the workload of on-site drilling and bolt connection, improving assembly convenience and efficiency. It also lowers the accuracy requirements for drilling in the formwork, enhancing processing ease. Simultaneously, the detachable truss support structure is reusable, reducing processing costs and significantly improving the support strength during pouring. This prevents deformation and bulging during concrete pouring, improving pouring quality and making it highly applicable. Attached Figure Description

[0031] 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.

[0032] Example

[0033] See Figures 1 to 7As shown, a detachable truss support structure for a formwork-free installation includes a formwork-free installation 1 and several detachable truss support structures 3 connected to the side of the formwork via a connecting structure 2. In this embodiment, during fabrication, the detachable truss support structure includes two lower chords 31, one upper chord 32, several web members 33, and several vertical members 34. The length of the lower chord is 3300mm, and the length of the upper chord is 2700mm. The height between the upper and lower chords is 200-500mm, and the width between the two lower chords is 200-500mm. These dimensions improve the overall structural support strength and enhance the quality of concrete pouring, preventing deformation and bulging during the pouring process. The upper chord, lower chord, web members, and vertical members are reinforced concrete structures or steel pipe structures. Using steel pipe structures helps reduce the overall structural weight. In actual processing, the various structures of the detachable truss are fixed by welding, screw fixing, or clip fixing, which can be selected according to needs.

[0034] In this embodiment, during processing, the two lower chords are arranged parallel to each other, and the upper chord is parallel to the lower chords, with the upper chord positioned on the midline of the two lower chords. The bottom ends of the web members and the vertical members are respectively fixed to the lower chords, and the top ends of the two web members and the top end of the vertical member are fixed to the same position on the vertical member, with the two web members and the vertical member arranged in a U-shape. The web members on the two lower chords are symmetrically arranged with the upper chord as the centerline. Furthermore, the lower chords are attached to the side of the non-removable formwork and fixed through a connecting structure. Through the above structure, the overall structure can be made three-dimensional, thereby improving the effectiveness and strength of the support during concrete pouring and preventing deformation and bulging during the concrete pouring process.

[0035] Furthermore, in this embodiment, the distance between the fixing points of adjacent vertical bars on the upper chord is 200-500mm.

[0036] In practical applications, the connecting structure includes a connecting steel plate 21 and two tie rods 22. In this embodiment, the connecting steel plate is 400mm long and 100mm wide. The connecting steel plate is fixed on the non-removable template, and the connecting steel plate is provided with two screw holes symmetrical about the vertical centerline. During assembly, the tie rods are connected between the connecting steel plate and the lower chord and locked in place.

[0037] In this embodiment, the removable formwork includes vertical reinforcement 11, horizontal reinforcement 12, and concrete. During assembly, the vertical and horizontal reinforcements are arranged in a cross shape, and the concrete covers the vertical and horizontal reinforcements. The thickness of the removable formwork is 3-5 cm.

[0038] To facilitate the relocation of the formwork, several handles 4 are fixed to its surface. These handles are made of metal and serve to connect the formwork to the poured concrete, while also functioning as lifting hooks during hoisting.

[0039] This utility model has the following positive effects: Its structure is rationally designed. The detachable truss support structure is fixed to the formwork without needing to be removed via a connecting structure. The detachable truss support structure can be disassembled and assembled from the formwork as needed, facilitating transportation. Furthermore, the connecting structure reduces the workload of on-site drilling and bolt connection, improving assembly convenience and efficiency. It also lowers the accuracy requirements for drilling in the formwork, enhancing processing ease. Simultaneously, the detachable truss support structure is reusable, reducing processing costs and significantly improving the support strength during pouring. This prevents deformation and bulging during concrete pouring, improving pouring quality and making it highly applicable.

[0040] The standard parts used in this embodiment can be purchased directly from the market, and the non-standard structural parts described in the instruction manual can also be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0041] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all embodiments here. However, these obvious variations or modifications derived from the essential spirit of this utility model still fall within the protection scope of this utility model.
