Abstract

The invention relates to a composite insulating energy-saving light concrete wallboard as well as a preparation method thereof. The wallboard comprises an aerated concrete core plate, wherein wallboard composite surface layers are spliced on two surfaces with the maximum area of the aerated concrete core plate. The preparation method comprises the following steps: preparing slurry; preparing a framework of steel reinforcement; preparing the aerated concrete core plate; and finally preparing the wallboard. The wallboard has good building energy efficiency and meets the demand of circular economy. The wallboard prepared is internally provided with the framework of steel reinforcement, so that the wallboard has good sound insulating performance, high breaking strength and good nailing and hanging performance. The calcium silicate board veneering light wallboard fully meets the demand of wall function and creates advantages for environment-friendliness, energy saving, waste utilization and circular economy, so that the wallboard is the optimum product for revolution of current wall materials. Therefore, the wallboard has a good development prospect.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a composite thermal insulation and energy-saving lightweight concrete wallboard and a preparation method thereof. Background technique [0002] A wall panel is a building structure that consists of walls and floors that form a load-bearing system. The wall is not only a load-bearing member, but also a room partition. It is the most commonly used and economical structural form in residential buildings. The disadvantage is that the flexibility of the indoor layout is poor. In order to overcome this disadvantage, it is currently developing in the direction of large bays. The wall panel structure is mostly used in houses, apartments, and public buildings such as office buildings and schools. Load-bearing walls of panel construction can be made of bricks, blocks, precast or cast-in-place concrete. [0003] Existing ordinary concrete wall panels are of single structure, and...
