Prefabricated anti-water-seepage dismounting-free shear wall form board

Abstract

A prefabricated anti-water-seepage dismounting-free shear wall form board comprises an inner form board (1), an outer form board (2) and an inner and outer form board connecting part (3), and the inner form board (1), the outer form board (2) and the inner and outer form board connecting part (3) are rigidly connected. Mortise and tenon joint structures are arranged on the edges of the inner formboard (1) and the outer form board (2), and the adjacent inner form board (1) and outer form board (2) are in butt joint and assembled correspondingly through the mortise and tenon joint structures. Sealing strips (4) are arranged on the inner sides of mortise structures of the mortise and tenon joint structures, during form board assembling, the corresponding mortise and tenon joint structures are in butt joint, and the sealing strips (4) effectively avoid seepage of water in concrete. Supporting structures are arranged on the outer sides of the inner form board (1) and the outer form board (2). The inner form board (1) and the outer form board (2) each comprise an outer layer, an inner layer and a steel bar mesh embedded in the inner layer. By means of the prefabricated anti-water-seepage dismounting-free shear wall form board, adverse factors brought by traditional form boards are reduced, meanwhile, structure durability is improved, the later maintenance cost of the structure is reduced, and the service life of the structure is finally prolonged.

Description

technical field [0001] The invention relates to the technical field of building exterior walls, in particular to a prefabricated and assembled anti-seepage formwork for a shear wall without dismantling. Background technique [0002] In the traditional shear wall construction, after the steel bars are bound, the workers install the external and internal templates and support systems on the scaffolding platform and the floor respectively, and the internal and external templates are internally supported (generally fixed on the reinforcement cage with steel bars of equal length to the wall thickness) ) and the paired bolts or the paired flat irons form a concrete pouring cavity, and after the concrete reaches the formwork removal strength, the formwork and supports are removed. [0003] At present, in the field of domestic construction, wooden formwork, steel formwork and other formwork are usually used in building structures, which have disadvantages such as large consumption, ...

AI Technical Summary

Problems solved by technology

The prefabricated shear wall is simple in construction and suitable for industrial production, but the stiffness of the shear wall is greatly weakened

At present, the construction process of cast-in-place concrete shear walls is usually binding steel bars ~ supporting formwork ~ pouring concrete ~ removing formwork ~ decoration. high cost
