Embodiment 1

[0031] Figure 1 to Figure 8 It shows the first embodiment of the formwork assembly used for the side wall of the subway station in the present invention, the formwork assembly includes a support frame 1 and a panel 2, the panel 2 is arranged on the support frame 1, and the main back of the panel 2 is connected with the support frame 1 is provided with an adjustment part 3 for adjusting the horizontal displacement and verticality of the panel 2. After adjustment, the bottom of the panel 2 is tightly connected to the support frame 1 through the connecting part 4, and the bottom of the support frame 1 is connected to the main structure through the embedded part 5. baseplate connection. During construction, the embedded part 5 is buried first, and the support frame 1 is hoisted to the top of the bottom plate to fasten the embedded part 5 after the concrete pouring of the bottom plate of the main structure meets the design requirements, and then the panel 2 is connected to the sup...

Embodiment 2

[0044] Figure 2 to Figure 9 It shows the second embodiment of the formwork assembly used for the side wall of the subway station of the present invention, the formwork assembly is basically the same as Embodiment 1, the only difference is that the bottom of the support frame 1 is connected to the center of the main structure through the embedded part 5 plate connection; the avoidance bevel at the bottom of the front end of the base 11 can avoid collision with the water retaining sill of the middle plate; the bottom of the embedded part 5 is bent at 90° to form a bending part, which can prevent the embedded part 5 from coming out on the one hand and improve On the other hand, the tensile force of the embedded part 5 can adapt to the middle plate structure with a smaller thickness.

[0045] The on-site construction process of the formwork component system is as follows: 1. Embedded parts 5 are buried, installed immediately after the bottom plate or middle plate steel bars are b...

Abstract

The invention discloses a template component for a sidewall of a subway station. The template component comprises a support frame and a panel, wherein the panel is arranged on the support frame; a regulation part for regulating the horizontal displacement and the perpendicularity of the panel is arranged between a main back arris of the panel and the support frame; after the panel is regulated, the bottom is fixedly connected with the support frame through a connecting part; the bottom of the support frame is connected with a bottom plate or a middle plate of a main body structure through an embedded part. The template component has the advantages of simple structure, high rigidity, convenience for operation, good anti-thrust and floating prevention effects, sidewall board smoothness, high construction quality and standardization degree and adjustability for the horizontal displacement and the perpendicularity of the panel.

Description

technical field [0001] The invention mainly relates to underground engineering construction technologies such as subway stations, and in particular to a formwork assembly used for side walls of subway stations. Background technique [0002] Since the subway station is an underground project and has high waterproof requirements, the side wall formwork of the subway station is a single-sided formwork stress system. At present, the side wall formwork systems of subway stations mainly include full-frame counter-bracing systems, diagonal bracing systems, triangular truss support systems, and trolley formwork systems. Affected by the structure of the formwork, the existing formwork and support system are mostly fastened together. After installation, the verticality of the panel and the front and rear displacement are extremely difficult to adjust. The process of assembling the formwork is complicated. . Contents of the invention [0003] The technical problem to be solved by t...
