Stone facing prefabricated external wall plate as well as production method and external wall system thereof

Abstract

The invention discloses a stone facing prefabricated external wall plate as well as a production method and an external wall system thereof. The stone facing prefabricated external wall plate comprises a stone facing layer, a heat preservation material layer and a concrete structural layer which are arranged layer by layer through a connection piece, wherein the stone facing layer comprises a stone plate; a mounting slot is formed in the side end face of the stone plate; the connection piece comprises a connection plate and a hooking end; the connection plate is perpendicular to layering surfaces; the hooking end extends from the end part of the connection plate to the direction perpendicular to the connection plate; the hooking end is fixedly embedded into the mounting slot; the connection plate penetrates through the heat preservation material layer and is embedded to be anchored into the concrete structural layer. The mounting slot is formed in the side end face of the stone plate, so that the thickness of the stone facing layer can be reduced; therefore, the whole thickness and the weight of the external wall plate are reduced; the load contribution of the assembled external wall system to a building main body is small, heat isolation and drying heat preservation are facilitated, and the building energy consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of exterior walls of prefabricated buildings, in particular to a stone-faced prefabricated exterior wall panel, a production method thereof, and an exterior wall system assembled from the exterior wall panel. Background technique [0002] Traditional residential buildings adopt the method of pouring concrete on site. The on-site construction of the main structure of the external wall generally needs to go through processes such as supporting formwork, laying steel bars, pouring concrete, and demolishing the formwork. A series of tedious work such as decorative layer construction and interior decoration construction; this construction method has a long cycle, requires a lot of manpower, serious waste of materials, and a lot of construction waste. [0003] With the development of housing industrialization, prefabricated exterior wall panels and exterior wall systems suitable for my country's building construct...

AI Technical Summary

Problems solved by technology

[0006] Based on this, it is necessary to provide a prefabricated exterior wall panel with stone veneer for the problems of large wall thickness, high self-weight, difficult processing, high assembly requirements, and high production cost, and at the same time provide its production method and the characteristics of the exterior wall panel. assembled façade system
