Description

Technical Field

[0001] This utility model relates to the field of template bracing structure technology, specifically to a lateral support device for templates used in the construction of ultra-high cantilever shear walls. Background Technology

[0002] During the construction of shear walls, diagonal bracing is an important load-bearing component. Existing diagonal bracing reinforcement methods mostly adopt welding fixation or simple bolt connection, which have the following problems: (1) Traditional reinforcement components are mostly customized structures, which are only applicable to diagonal bracing of specific specifications and have poor versatility; (2) The lateral stability of existing diagonal bracing is limited and cannot adapt to the lateral load of ultra-high cantilever shear walls. Under large loads, it is easy to produce bending deformation and poor overall stability; (3) The adjustment range of bolt-connected reinforcement devices is limited and it is difficult to adapt to the small angle deviation during the installation process of diagonal bracing. Loosening is easy to occur, affecting the overall stability. Utility Model Content

[0003] The purpose of this invention is to provide a lateral support device for formwork in the construction of ultra-high cantilever shear walls. This device is used to solve the technical problems of poor versatility, poor stability, and inability to adjust to installation errors in traditional reinforcement components in the prior art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A lateral support device for formwork in the construction of an ultra-high cantilever shear wall includes diagonal bracing members and an adjustable support assembly. Multiple diagonal bracing members are spaced apart and arranged between the shear wall formwork and the structural foundation. The adjustable support assembly includes a connecting seat, a vertical support rod, an adjustable support rod, a first connecting member, and a second connecting member. One end of both the vertical support rod and the adjustable support rod is hinged to the connecting seat. The first connecting member is hinged to the bottom of the vertical support rod, and the second connecting member is hinged to the bottom of the adjustable support rod.

[0005] Preferably, the diagonal brace includes a main diagonal brace, an adjusting diagonal brace, an upper diagonal brace connector, and a lower diagonal brace connector. The adjusting diagonal brace is threadedly adjustable to one end of the main diagonal brace, and the lower diagonal brace connector is hinged to the other end of the main diagonal brace. The upper diagonal brace connector is connected to one end of the adjusting diagonal brace connector via a ball joint.

[0006] Preferably, the connecting seat includes a base body, a cover body, and connecting arms. The cover body is detachably mounted on the base body, and the two connecting arms are fixedly mounted on one side of the base. The vertical support rod and the adjustable support rod are mounted inside the two connecting arms.

[0007] Preferably, a gasket ring is provided in the seat and the cover.

[0008] Preferably, it further includes a tie assembly, which includes a tie rod, a first U-shaped member and a second U-shaped member, both of which are detachably mounted on the tie rod; the first U-shaped member is connected to the vertical support rod and the second U-shaped member is connected to the diagonal brace.

[0009] In this invention, by adding adjustable support components, a dual support system of "diagonal bracing + adjustable support components" is formed. The adjustable support rods not only increase the number of lateral support points for the formwork but also distribute the load borne by a single diagonal bracing, effectively reducing the risk of deformation of the formwork due to load concentration in ultra-high cantilever conditions. The tie components set up form a force-linked whole between the adjustable support components and the diagonal bracing, reducing the independent stress deformation of the support structure and improving the overall overturning resistance and structural strength of the support system.

[0010] The connector's base and cover are detachably connected, and an inner washer structure allows for the replacement of washer rings of different sizes to accommodate diagonal bracing main rods of varying diameters. This eliminates the need for separately designed connectors for different sizes of diagonal bracing components, significantly reducing the production and procurement costs of specialized accessories. The overall structure is designed for detachable installation, enabling repeated disassembly and reuse of each component, reducing material waste during construction, and facilitating rapid installation and replacement, thus shortening the erection and dismantling time of the formwork support system.

[0011] The ball joint connection and adjustable structure design can flexibly compensate for construction errors during the installation and support of the formwork. For example, minor positional deviations during formwork assembly can be corrected by adjusting the length of the diagonal brace and rotating the angle of the ball joint, avoiding formwork misalignment due to the inability of the support device to adapt to the error, thereby reducing appearance defects after the shear wall is poured.
