Heat preservation and sound isolation wall block with a mutually buckled structure

Abstract

The invention discloses a heat preservation and sound isolation wall block with a mutually buckled structure and belongs to the technical field of building materials. A block body is prepared from cement, coal ash, river sand, water, a cement foaming agent and a foam stabilizer through stirring, foaming and molding. Two heat preservation and sound isolation tanks with bottoms are arranged on the top face of the block body in a row in the length direction, and the heat preservation and sound isolation tanks are filled with heat preservation and sound isolation composite materials. A convex portion is formed on one end face of the block body, and a concave portion corresponding to the convex portion in shape is formed in the other end face of the end opposite to the end face with the convex portion. The convex portion and the concave portion are buckled when a wall is built, so that the strength of the wall is enhanced. The heat preservation and sound isolation lightweight aggregate block has high pressure resistance and shear strength and good heat preservation and sound isolation effects, is an ideal material for building various walls, and is particularly suitable for various heat preservation building walls.

Description

technical field [0001] The invention relates to building wall materials, more specifically to the structure of a multifunctional lightweight aggregate block with the main advantage of heat preservation and sound insulation, and belongs to the technical field of building materials. Background technique [0002] Concrete blocks, which are commonly used as wall materials at present, are provided with single or double rows of holes on the block, and their thermal insulation performance is poor. With the improvement of building energy-saving requirements, the thermal performance of building envelopes It has attracted much attention; one of the effective ways to meet the higher requirements of building energy conservation is to focus on the development of the self-insulation system of the enclosure structure, that is, to improve the thermal insulation and sound insulation performance of the wall material itself. To develop a wall material with high thermal insulation and sound ins...

AI Technical Summary

Problems solved by technology

Hollow wall bricks made of this kind of material or through-holes in the middle have certain thermal insulation and sound insulation effects when used in buildings. However, due to the solidity of the side walls of the through-holes, the thermal insulation and sound insulation effects are affected, and it still cannot meet the needs of the construction market.
