Prefabricated low-mass, heat-preservation and noise-reduction wallboard and preparation method thereof

Abstract

The invention relates to the technical field of wallboards, and discloses a prefabricated low-mass, heat-preservation and noise-reduction wallboard and a preparation method thereof. The wallboard comprises a three-layer structure: two outer side layers are reinforced concrete layers, and a middle layer is a porous mixture sandwich layer; reinforcements penetrating through the three layers are arranged in the wallboard; and bamboo and wood mixed fibers are arranged in the porous mixture sandwich layer. The preparation method comprises the following steps: 1) one reinforced concrete layer is prepared; the reinforcements are embedded before solidification; and the two ends of the reinforcements penetrate through the surface of the reinforced concrete layer; 2) after solidification, the reinforced concrete layer is in vertical butt joint with the other reinforced concrete layer just cast; and the reinforcements are inserted in the other reinforced concrete layer to form a two-layer hollowbody; 3) after solidification, the hollow body is vertical for pouring casting materials in the porous mixture sandwich layer; and 4) finished products are obtained after curing in constant-temperature and constant-humidity environments. The wallboard is novel and unique in structure, low in weight, excellent in heat preservation and noise reduction effect and quick in transportation and installation, and can realize large-batch assembly type automatic production.

Description

Technical field [0001] The invention relates to the technical field of wallboards, in particular to a prefabricated and assembled light-weight thermal insulation and noise-reducing wallboard and a preparation method thereof. Background technique [0002] Most of the existing wallboard construction methods are bricklaying or cast-in-place moulding, which is labor intensive, requires a lot of consumables, and the construction period and cost are high. Although there are some prefabricated wall panels on the market, they are generally self-heavy and inconvenient for transportation. At present, the prefabricated wall panels for heat preservation and noise reduction in the market are in order to achieve high temperature and noise reduction effects. , Lightweight porous cement, such as foamed cement, is widely used, which not only has unsatisfactory insulation and noise reduction effect, but also its strength cannot meet the application in many fields (the strength of foamed cement is ...

AI Technical Summary

Problems solved by technology

[0002] Most of the existing wallboard construction methods are bricklaying or cast-in-place formwork, which is labor-intensive, consumes a lot of materials, and the construction period and cost are relatively high.

Although there are some prefabricated wall panels on the market, they generally have the disadvantages of being heavy and inconvenient to transport, and the prefabricated wall panels currently on the market for heat preservation and noise reduction are designed to achieve high temperature and noise reduction effects. , generally use lightweight porous cement such as foamed cement, etc., not only the thermal insulation and noise reduction effect is not ideal, but also its strength cannot meet the applications in many fields (the strength of foamed cement is low)
