Outer wall surface transformation method without removing original outer wall surface

Abstract

The invention discloses an outer wall surface transformation method without removing an original outer wall surface. The outer wall surface transformation method comprises the following steps that a first layer of interface agent is brushed on a structural base layer of the original outer wall surface after an aged outer wall surface is removed; cement mortar continues to be smeared on the surface of the first layer of interface agent till an original ceramic tile surface / original plaster layer is leveled; the surface of the cement mortar is continuously coated with a second layer of interface agent and an adhesive in sequence, an extruded sheet is anchored into the surface of the adhesive, and the extruded sheet is fixed to the structural base layer of the original outer wall surface after the aged outer wall surface is removed through anchor bolts; and the surface of the extruded sheet is sequentially coated with a layer of anti-crack mortar, putty powder and exterior wall paint. According to the outer wall surface transformation method, the risk of falling of construction waste is reduced, the safety protection pressure is reduced, collection and transfer of the construction waste are reduced, manpower and material resources are saved, and the construction period is shortened.

Description

technical field [0001] The invention relates to the field of exterior wall reconstruction methods. More specifically, the present invention relates to a method for renovating an exterior wall without removing the original exterior wall. Background technique [0002] Due to the influence of various factors such as construction period and construction method, the old buildings can no longer adapt to the development of modern cities. It is very necessary to upgrade and renovate these old buildings. Among them, the renovation of building facades occupies a major position in the entire renovation work, while the reconstruction of walls in existing facade renovations usually directly removes the original exterior walls, and then carries out corresponding decorations according to the design, in order to achieve The effect of the design. [0003] The method of directly removing the original outer wall will cause secondary damage to the original wall and affect the structural safet...
