Abstract

The invention discloses an outer wall outer heat-preservation system with a gel glass bead heat-preservation plate. The outer wall outer heat-preservation system is applied to the field of building wall bodies and is a renewal product of an existing outer wall heat-preservation system. According to the key points of the technical scheme, the outer wall outer heat-preservation system comprises a bonding layer, a heat-preservation layer, a plastering layer and a facing layer which are sequentially arranged on a base layer wall body; the bonding layer is formed by coating of bonding mortar; the gel glass bead heat-preservation plate serves as the heat-preservation layer; the plastering layer is formed by coating of plastering mortar and internally provided with an alkali-resistant glass fibergrid cloth; and the facing layer is formed by laying flexible facing bricks. The outer wall outer heat-preservation system prepared from all the layers has the advantages of excellent appearance quality, high wind-load resistance, high impact resistance, high freeze-thaw resistance, heat preservation, heat insulation, fire prevention and waterproofness.

Description

technical field [0001] The invention relates to a building wall system, in particular to an external thermal insulation system for an external wall of a gel glass bead thermal insulation board. Background technique [0002] In recent years, energy saving and environmental protection have become a common topic all over the world. With the implementation of my country's new building energy-saving standards, the building has developed from a low-level solution for people's living to a high-level green ecological building. In the heat consumption of buildings, the heat consumption of exterior walls accounts for about 30%. Therefore, how to reduce the K value of exterior walls is one of the main ways to reduce energy consumption of buildings. Therefore, exterior wall insulation technology has emerged as the times require. [0003] Among the many thermal insulation technologies, the one that can significantly reduce the K value is the external thermal insulation technology of ext...
