Manufacturing process of light prefabricated assembly type external wallboard

Abstract

The invention relates to a manufacturing process of a light prefabricated assembly type external wallboard. The manufacturing process comprises the following steps: (1) a through hole is formed in anouter base plate, a thermal insulation material is poured, to bond the outer base plate and an inner base plate, and an outer side plate is bonded through the through hole in the outer base plate, sothat the whole wallboard forms a whole; (2) a keel framework is manufactured, and a pouring hole is formed in one side wall of the keel framework; (3) the inner base plate is fixed to the inner side face of the keel framework through a penetrating connecting piece, the outer base plate and the outer side plate are fixed to the outer side face of the keel framework through the penetrating connecting piece, the outer side plate is located on the outer side of the outer base plate, and a pouring cavity is defined by the outer base plate, the keel framework and the inner base plate; (4) a thermalinsulation material is poured into the pouring cavity, and foaming is carried out; and (5) after the thermal insulation material is solidified, the whole wallboard is moved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a manufacturing process of a light-weight prefabricated exterior wall panel. Background technique [0002] Vigorously develop prefabricated buildings, realize industrialization of building parts production, integration of technology applications, standardization of engineering design, assembly of on-site construction, integration of civil engineering and decoration, and informatization of life cycle management. This is a profound change in the industrial transformation and upgrading of the construction field. Major innovations in construction technology and engineering construction methods are an inevitable trend in the development of green buildings and building energy conservation. They are conducive to reducing resource and energy consumption, reducing construction waste and dust pollution, improving construction efficiency and building quality, and contributing to building in...

Problems solved by technology

[0003] The wall panels of the traditional prefabricated concrete structure are generally reinforced concrete wall panels, which are heavy, and the production, transportation and construction costs are high; the wall panel technology of the traditional prefabricated steel structure is not perfect, and there are still thermal bridges, roof panel leakage, and floor panel sound insulation and the poor heat insulation effect of the wall; the level of industrialization and standardization of building components is low, and it does not match the main body of the steel structure building, which no longer meets the requirements of the modern development of my country's construction industry
