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...

The invention patent with the application number CN201510906488 "An Assembled Composite Wallboard and Its Manufacturing Method Based on Foamed Cement External Thermal Insulation Treatment" discloses a composite wallboard and its manufacturing method, which plays a positive role in promoting the development of composite wall materials. However, the production cycle of the invention is long, the weight of the composite wallboard is large, and the construction requirements are relatively high, so it is difficult to achieve large-scale popularization and application

The invention patent with the application number CN201610167280 "Assembled EPS Module Sandwich Thermal Insulation Composite Wall Panel for Steel Structure Wall" discloses a thermal insulation composite wall panel specially used for supporting steel structure buildings, which has good strength and thermal insulation performance , but this kind of composite wallboard needs waterproofing, heat preservation, decoration and other constructions after installation, the process is complex, the construction period is long, and the level of industrialization is low

[0003] At this stage, there are few applications of integrated wall panels for building exterior wall decoration on the market, and the construction speed of traditional wall panels is slow, the overall cost is high, and the quality of the project is difficult to guarantee. Shrinkage cracking, hollowing and other phenomena are prone to occur, which seriously affects the later use

At present, most wall panels are mainly suitable for building interior partition walls, and have not been treated with internal and external finishes. After the wall panels and core panels are installed, the base treatment of the walls and the decorative decoration of the walls still need to be carried out on site. The degree of worker approval is low. , The construction process is complicated, the efficiency is low, and the follow-up project quality problems are difficult to be held accountable, which no longer meets the requirements of the modernization development of my country's construction industry

[0004] Some enterprises have developed thermal insulation and decoration integrated wall panels in recent years, but most of them can only be used for internal partition walls. The prefabricated wall panels that can be used for external walls are mainly prefabricated sandwich concrete panels. The leaf wall is easy to fall off, and it is impossible to provide an integrated solution for exterior wall insulation and decoration
