Assembled external wall plate and preparation method thereof

Abstract

The invention relates to the field of a building material, in particular to an assembled external wall plate. The assembled external wall plate comprises an outer side plate, an inner side plate and a multifunctional structure layer, wherein the multifunctional structure layer is arranged between the outer side plate and the inner side plate; one side of the outer side plate is connected with one side of the multifunctional structure layer; an outer decoration layer is compounded at the other side of the outer side plate; one side of the inner side plate is connected with the other side of the multifunctional structure layer; an inner decoration layer is compounded at the other side of the inner side plate; the multifunctional structure layer comprises a force bearing frame; and waterproof heat insulation and heat preservation materials are filled in gaps between the outer side plate and the force bearing frame and gaps between the inner side plate and the force bearing frame. The quality can be ensured; the construction and the hoisting are easy; the construction efficiency is improved; the integral performance is stable; the impact resistant performance is good; the conventional common quality faults of wall plate cracking and deformation, edge missing, corner falling and the like can be avoided; after once installation completion, the veneer construction is not needed; and the engineering manufacturing cost and the construction period are reduced.

Description

technical field [0001] The invention relates to the field of building materials, in particular to an assembled exterior wall panel and a preparation method thereof. Background technique [0002] In order to meet the needs of green building development, vigorously develop the industrial manufacturing and application technology of composite wall materials. The construction of traditional exterior wall panels needs to go through a complex process of "setting-out-cutting-sizing-installation-adjustment-correction-grouting and grouting-fixing", and is faced with the problem that the load-bearing wall and thermal insulation system are not fully integrated. Construction Low efficiency, serious environmental pollution (construction waste per unit of GDP ranks first in the world), difficulty in guaranteeing project quality, and high labor costs. Compared with the development of prefabricated concrete structural components and steel structural components, the development of wall panel...
