Dismantling-free high-strength building formwork

Abstract

The invention provides a disassembling-free high-strength building formwork, which comprises a net surface, a core body and a connecting structure. The net surface is arranged in the surface of the core body, the embedded depth in the surface of the core body is not more than 3 millimeters; the net surface is made of net cloth with meshes. The core body is formed by solidifying gypsum slurry whichis formed by mixing and stirring high-strength gypsum powder, fiber, additive and water; the fiber length is 0-16 millimeters, and the weight percentage of the fiber to the core body is 0.05%-0.1%. Aconnecting structure is arranged at the periphery of the formwork core body, and is used for connecting the formworks and the connection between an external fixing device and the formworks. The fiberis added into the core body, so that the strength of the formwork is increased, the phenomenon that the formwork is damaged due to the formwork expansion caused by the large vibration intensity is avoided, the combination performance of the gypsum and concrete is utilized, so that the formwork is integrated with the building component, and the efficiency is improved and the cost is saved.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a disassembly-free high-strength building template used when pouring concrete in building 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.

[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

Aiming at the deficiencies of the existing technology, a disassembly-free building formwork was invented. However, during the concrete pouring process, it needs to be vibrated by vibrating rods. During the vibrating process, due to the different vibration time and intensity, the disassembly-free building formwork will be damaged and deformed.
