Abstract

The invention discloses an assembly type vacuum heat insulation composite wallboard which comprises GFRP profile plates, the GFRP profile plates are filled with composite heat insulation layers, male and female fasteners are arranged on the side faces of the GFRP profile plates, the multiple GFRP profile plates are connected through the male and female fasteners to form a whole to serve as a framework, outer side ribs are distributed on the upper end faces of the GFRP profile plates, and RPC concrete is poured on the upper end faces of the GFRP profile plates. Inner side ribs are arranged on the lower end face of the GFRP profile plate, a fine stone mortar leveling layer is laid on the lower end face of the GFRP profile plate, and the GFRP profile plate is in bolted connection with the prefabricated GFRP connecting fastener. The GFRP sectional material plate with good thermal performance and stress performance serves as a framework, the prefabricating and assembling efficiency is improved, a heat bridge generated by frequently using steel in the prior art is avoided, interface connection between different materials in the wallboard is achieved through mechanical connection in the mode that the ribs, the bonding glue layer and the male and female fasteners are arranged, and the heat insulation performance of the wallboard is improved. And the completeness of the wallboard is ensured.

Description

technical field [0001] The invention relates to an assembled vacuum heat-insulating composite wallboard and a production process thereof. Background technique [0002] With the rapid development of urban construction and the country's increasing attention to prefabricated passive buildings in recent years, reducing building energy consumption, making low-carbon environmental protection and external wall panels that meet passive buildings have become hot spots in recent years. [0003] Traditional reinforced concrete composite slabs have the characteristics of steel corrosion, high quality, and complicated construction techniques. With the continuous rise in steel prices in recent years and the country's continuous improvement in energy cleanliness, a new material is urgently needed to replace steel. Compared with steel, FRP material has light weight, small specific gravity and high strength. At the same time, it has strong corrosion resistance. As a polymer organic composite...
