Construction method for external wall surface washed stones

Abstract

The invention belongs to the technical field of building outer wall construction, and discloses a construction method for outer wall surface washed stones. The construction method comprises the following steps: conducting base layer treatment, specifically, plastering or brushing an interface agent on an outer wall to obtain a washed stone wall surface base layer; snapping lines, specifically, snapping grids/dripping sutures on the outer wall; pasting grid division strips and water dripping strips, specifically, arranging the grid division strips or the water dripping strips according to the grids/dripping sutures; brushing cement mortar, specifically, scraping the cement mortar on a wet base layer to form a cement mortar layer; smearing a washed stone slurry surface layer, specifically, smearing washed stone slurry on the cement mortar layer, and kneading, pressing and compacting to form the washed stone slurry surface layer; flushing the surface layer, specifically, after initially setting the washed stone slurry surface layer, flushing the surface of the surface layer by using an under-pressure spray head to expose the washed stones and form a washed stone surface; and forming strips and pointing, specifically, after naturally air-drying the washed stone surface, forming dividing strips and water dripping strips, and conducting pointing through cement and fine sand mortar. The construction method is short in construction period, suitable for large-area outer wall decoration, not prone to stripping, resistant to pollution, free of discoloration and good in economic benefits.

Description

technical field [0001] The invention belongs to the technical field of building exterior wall construction, and in particular relates to a construction method of washed stone on the exterior wall. Background technique [0002] With the vigorous development of my country's construction industry, building exterior wall decoration projects are also developing rapidly. Existing exterior walls of buildings are mostly decorated with wall bricks and paint, but as time goes by, the walls of wall bricks and paint layers of many construction projects have cracked, bulging, falling off, discoloration, and water seepage within a few years after completion. And other problems, seriously affect the facade effect and aesthetics of the building. [0003] The essence of washed stone is similar to that of washed stone. It has physical properties and characteristics such as high density, high hardness, wear resistance, no dust, and not easy to peel off. It also has good water permeability, an...

AI Technical Summary

Problems solved by technology

Washed stone raw materials have different colors and shapes, and are widely used in interior decoration and outdoor landscape modeling; however, they are rarely used in large-area building exterior wall decoration.

The traditional washed stone construction method is mostly suitable for laying roads and small-area wall construction, but not suitable for laying large-area exterior walls, and is prone to problems such as hollowing and cracking. Therefore, the present invention is based on the traditional washed stone construction method. Provides A washed stone construction method suitable for large-area decoration of building exterior walls
