Dismounting-free building formwork

Abstract

The invention relates to a dismounting-free building formwork and belongs to the field of buildings. The dismounting-free building formwork comprises a mesh face, a core body and connecting structures. The mesh face is arranged in the surface of the core body and embedded into the surface of the core body by no more than 3 mm. The mesh face is made of a gridding cloth with mesh holes, and the gridding cloth is made of alkali-resistant glass fibers, glass fibers, nylon, natural fibers and metal wires which are woven or pressed. The core body is a mixed material constituted by high-strength gypsum powder and an additive. The additive comprises a water reducer. The connecting structures are arranged on the periphery of the core body of the formwork, the time for formwork dismounting and formwork materials can be saved greatly, and the formwork and a building component can be formed into a whole; and meanwhile, owing to the fact that gypsum has the characteristics of being light, free of pollution, resistant to heat and poor in heat conduction property, the gypsum can adhere to the surface of the building component to form heat insulation and decoration layers, and the subsequent project amount is reduced.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a disassembly-free formwork used when pouring concrete in construction. Background technique [0002] In building construction, due to structural requirements, it is often necessary to cast some building components on site. During pouring, a formwork of a corresponding shape is installed on the periphery of the casting component to form an inner cavity with the same shape as the component. Concrete and other slurries with fluidity; in the existing pouring process, the peripheral formwork is mostly made of wood or steel, and the formwork needs to be erected before pouring, and the formwork needs to be disassembled after pouring, which seriously affects the construction of construction projects Cycle, and need to waste a lot of wood and steel plate, resulting in increased construction costs. Contents of the invention [0003] In view of the above-mentioned problems existi...
