A preparation process for ultra-thin prefabricated thermal insulation exterior wall panels for building industrialization

Abstract

The invention provides a preparation process for an ultra-thin prefabricated heat preservation outer wall plate for building industrialization. The preparation process comprises the following steps that (1) a well prepared concrete material is placed in an inner mould to be poured and tamped to obtain a prefabricated inner layer plate; (2) a well prepared concrete material is placed in an outer mould to be poured and tamped to obtain a prefabricated outer layer plate; (3) a reinforcement material is poured and tamped on the portion, corresponding to a boss structure, of the outer layer plate, and then a heat preservation material covers the surface layer of the reinforcement material; and then (4) the inner layer plate is arranged on the outer layer plate in an overlapped and inverted mode, a reinforcement material is poured and tamped on the portion, corresponding to the boss structure, of the inner layer plate, and the ultra-thin prefabricated heat preservation outer wall plate is obtained after curing and solidification. According to the heat preservation outer wall plate, an inner concrete layer and an outer concrete layer adopt the outer concrete material to wrap the RPC concrete material, on the one hand, overall strength is improved, and on the other hand, the cost can be effectively reduced; and the associative property of the inner layer and the heat preservation material as well as the outer layer and the heat preservation material is high, the inner layer, the outer layer and the heat preservation material make contact with one another and are solidified, the cracking and peeling phenomena are significantly reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a preparation process of an ultra-thin prefabricated thermal insulation exterior wall panel for building industrialization. Background technique [0002] The industrialization of construction is to use the large-scale industrial production mode to construct industrial and civil buildings. It is the whole process of the construction industry gradually transitioning from the small manual production mode to the socialized large-scale production mode. At present, most of the external wall panels in building industrialization are designed as sandwich wall panels, and the selection and thickness of the insulation layer depend on the climate conditions of different regions. There are two concrete layers in the sandwich wallboard, the outer and inner concrete layers, and different types of thermal insulation materials are designed in the middle of the inner and outer concrete ...

AI Technical Summary

Problems solved by technology

Although the ultra-thin thermal insulation exterior wall panels proposed in the prior art have a small weight, RPC removes the coarse aggregate to improve the homogeneity of the material. The material requirements are high, which greatly increases the material cost, and the molding conditions are strict and the process is difficult. not suitable for general use
