Self-thermal-insulation wall and manufacturing technology thereof

Abstract

The invention provides a self-thermal-insulation wall and a manufacturing technology thereof. The self-thermal-insulation wall comprises a main body frame, a main keel, an outer thermal insulation layer, a thermal insulation core layer and an inner thermal insulation layer. The outer thermal insulation layer and the inner thermal insulation layer are arranged on the two sides of the thermal insulation core layer correspondingly, the outer thermal insulation layer comprises a first cement pressure plate and a dovetail groove polystyrene plate, the inner thermal insulation layer comprises a second cement pressure plate and a dovetail groove polystyrene plate, and the dovetail groove polystyrene plates are installed towards one side of the thermal insulation core layer; and the thermal insulation core layer is foam concrete, slurry of the foam concrete is poured to the position between the inner thermal insulation layer and the outer thermal insulation layer, and after forming, the slurryis connected with dovetail grooves in the dovetail groove polystyrene plates on the two sides in a buckled mode. According to the self-thermal-insulation wall, the mutually buckled connecting state is formed between the thermal insulation core layer prepared from the foam concrete and the dovetail groove polystyrene plates on the inner thermal insulation layer and the outer thermal insulation layer, connection is stable and firm, so that the thermal-insulation wall has good integrality, the thermal insulation performance is better, and the service life is longer.

Description

technical field [0001] The invention relates to the technical field of thermal insulation walls, in particular to a self-thermal insulation wall and a manufacturing process thereof. Background technique [0002] Cement pressure board, also known as fiber cement pressure board or cement fiber pressure board, is a new type of building board made of natural fiber and cement through pulping, molding, cutting, pressing and curing. Belonging to a new generation of "green" building materials, it has unique environmental protection functions on the basis of excellent moisture-proof and fire-proof performance. It is a new type of building material based on silicon and calcium materials as the main base material, cellulose fiber reinforced material, and other auxiliary materials, which are formed by copying and high-pressure curing. It has the advantages of light weight, high strength, waterproof, anti-corrosion, fire prevention, large format, good processability, and improved constr...

AI Technical Summary

Problems solved by technology

[0003] The current formwork-free wall body uses cement pressure plates as templates alone, and a cavity is formed between the two cement pressure plates to pour foam concrete. Although the problem of form removal is solved, the thermal insulation effect of the foam concrete here is not ideal; and Because foam concrete is a cement product, it has low strength and some unstable factors. During the solidification and molding process of foam concrete, the expansion and shrinkage of foam concrete will cause certain damage to the integrity of the wall. After molding, foam concrete and The bonding between the cement pressure plates is not strong enough, and there are problems such as hollowing, which reduces the service life of the wall
