Manufacturing method of external wallboard

Abstract

The embodiment of the invention provides a manufacturing method of an external wallboard. The manufacturing method is applied to a concrete member prefabricating factory and particularly comprises thesteps of preparing a formwork; presetting an edge template and steel bars; pouring for the first time to form a wall foundation part; forming erecting again on the upper part of the wall foundation part, and arranging reinforcing mesh sheets; pouring with solid benzene particle concrete for the second time to form a heat insulation layer of the external wallboard; carrying out primary steam curing; pouring with mortar for the third time to form a thermal insulation mortar layer; carrying out secondary steam curing; and after the second steam curing is finished, carrying out natural curing, and finally forming a complete finished product of the external wallboard. Due to the fact that the external wallboard is manufactured in the concrete member prefabricating factory and in a controllableenvironment, the quality and quantity requirements of manufacturing the external wallboard can be guaranteed, and the completed external wallboards can be sent to a building site for installation intime, so that the problem that the construction period and the quality cannot be guaranteed under an existing open-air construction condition is solved.

Description

technical field [0001] The invention relates to the technical field of buildings, in particular to a method for making an exterior wall panel. Background technique [0002] At present, for permanent or semi-permanent buildings, the use of reinforced concrete and other building materials is still the mainstream, that is, the foundation is laid on the construction site, the steel bars are bundled on the foundation, and then the formwork is erected, and then concrete is poured to form the frame and floor of the building. , stairs, walls, etc., and finally complete the construction of the building after plastering and decoration. [0003] However, buildings generally adopt open-air construction, especially the outer wall as the main component, which needs to be formed by building blocks after the frame construction is completed. During the open-air construction process, wind, frost, rain and snow are often affected. First, construction cannot be carried out in bad weather, and ...
