Prefabricated sandwich insulation wall based on plate perforated FRP connecting pieces and manufacturing method thereof

Abstract

The invention discloses a prefabricated sandwich insulation wall based on plate perforated FRP connecting pieces and a manufacturing method thereof. The prefabricated sandwich insulation wall comprises an inner-layer concrete plate, an outer-layer concrete plate, a middle insulation layer and FRP connecting pieces; the inner-layer concrete plate and the outer-layer concrete plate are compounded byfiber knitted nets and ECC concrete; through transverse penetration of the FRP connecting pieces, the fixed connection among the inner-layer concrete plate, the middle insulation layer and the outer-layer concrete plate is realized; and holes are formed in the two side edge positions, in the inner-layer concrete plate and the outer-layer concrete plate, of the FRP connecting pieces at intervals.Through full use of such characteristics as high corrosion resistance and low heat conducting coefficient of the plate perforated FRP connecting pieces, the thermal bridge effect is eliminated, the safety and the durability of the wall are improved, and meanwhile, such problems as weak bonding and anchoring performances of connecting pieces of a traditional insulation wall with a sandwich layer and a concrete interface are solved.

Description

technical field [0001] The invention relates to a prefabricated sandwich insulation wall based on plate-type perforated FRP connectors and a manufacturing method thereof, belonging to the technical field of building construction. Background technique [0002] my country is a big country of energy consumption. About 30% of the total energy consumption is consumed in buildings. Building energy conservation is an important measure to alleviate energy shortages. Among them, improving the form of thermal insulation walls in wall energy conservation is the most important means to achieve building energy conservation. . At present, the insulation walls commonly used in construction engineering include internal insulation, external insulation and sandwich insulation walls. The internal insulation is inside the wall, which reduces the usable area of ​​the house and is greatly affected by the interior decoration. However, there are more serious fire prevention and durability problems...

AI Technical Summary

Problems solved by technology

[0007] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a prefabricated sandwich insulation wall based on plate-type perforated FRP connectors and its manufacturing method, making full use of the higher corrosion resistance of plate-type perforated FRP connectors The advantages of high thermal conductivity and low thermal conductivity can effectively avoid the thermal bridge effect produced by ordinary connectors, and at the same time solve the problems of poor bonding and anchoring performance between connectors and sandwich layers and concrete interfaces of traditional thermal insulation walls
