Problems solved by technology

However, this patent also has the following defects: first, vertical and horizontal ribs (2) are arranged on the outside of the polystyrene board (1), and multiple vertical and horizontal grooves need to be cut out on the outside of the polystyrene board during production, and then cement-based mortar is filled into the vertical and horizontal grooves. Form vertical and horizontal ribs
However, this patent also has the following defects: firstly, vertical and horizontal reinforcing ribs (2) are arranged on the outside of the polystyrene board (1), and multiple grooves need to be removed on the outside of the polystyrene board during production, and then cement-based mortar is filled into the vertical and horizontal grooves to form Vertical and horizontal ribs
[0007] There are also many patents on plant fiber boards. These boards such as plant fiber boards and straw boards must meet the heat insulation and thermal insulation properties required for building energy conservation. , it cannot be used alone as a thermal insulation formwork for buildings, and surface reinforcement layers must be made on both sides of it.
[0008] The technical problem to be solved by the present invention is: to solve the complex structure of the thermal insulation formwork for buildings, the strength of the plant fiberboard is not high when used as the thermal insulation formwork, especially when the vacuum insulation board is used as the insulation layer of the thermal insulation formwork, the The high gas barrier composite membrane is easy to be pierced or punctured by fixed connectors during the construction process.

Abstract

The invention discloses a heat-insulating demounting-free formwork for a building. The heat-insulating demounting-free formwork is characterized in that surface reinforcing layers are arranged on two sides of a heat-insulating layer; when the heat-insulating layer is a vacuum heat-insulating board, holes between the surface reinforcing layers are provided with hollow fixing members or filled with a gelatinizing material or a heat-insulating material, and the heat-insulating layer is fixed between the surface reinforcing layers. By the heat-insulating demounting-free formwork, the problem of insufficient strength occurring when a plant fiber board is used as a heat-insulating demounting-free formwork is solved, and the problem that a high-air-resistance composite film is prone to being pierced or punctured by a fixed connecting member in the process of construction when the vacuum heat-insulating board is used as the heat-insulating layer of the heat-insulating demounting-free board is solved. The heat-insulating demounting-free formwork has high economic benefit and social benefit in popularization and application.

Description

technical field [0001] The invention relates to the technical field of building structure system devices, in particular to a heat-preserving formwork for buildings without dismantling. Background technique [0002] The insulation-free formwork for buildings is a composite insulation board that is prefabricated in a factory and acts as a formwork in the construction of cast-in-place concrete. The insulation-free formwork for buildings has significant advantages such as light weight, high strength, heat insulation, fire prevention and impermeability, etc. Insulation for structural thermal bridges. It solves the common quality problems of cracking, hollowing, falling off, different lifespan from buildings, and poor fire performance in the current external wall insulation, and at the same time reduces the construction cost of the insulation layer. Realized wall insulation, concrete pouring one-time forming and energy saving and structural integration. [0003] There are some ...
