Construction technology of building external wall decoration with imitation stone effect

Abstract

The invention discloses a construction technology of the building external wall decoration with the imitation stone effect. According to an external wall constructed by using the process technology, the corrosion resistance, the crack resistance, the water resistance and the radiation resistance of the building external wall are greatly improved, the structure is rigid and firm, the external wall and a building wall surface are mixed into a whole, and the external wall cannot be faded or discolored permanently. The later load of a building is effectively reduced, and mixing is conducted by using quartz sand different in color so that the constructed wall surface can be imitated into various nature stones so as to be on a par with a stone cladding effect.

Description

technical field [0001] The invention belongs to the technical field of architectural decoration, and in particular relates to a construction process for building exterior wall decoration with imitation stone effect. Background technique [0002] At present, the construction industry usually adopts three methods for the wall surface and modeling decoration of the building's exterior wall: the first is to directly use the spraying process of paint coating or artificial stone paint; The spraying process of paint coating or imitation stone paint with GRC surface layer; the third is pasting ceramic tiles, wet pasting granite or dry hanging marble. The first type generally has defects such as severe cracking, shedding, powder removal, fading, easy mildew, corrosion, dust absorption, and easy dirt. And there is a short service life, and it needs to be painted again in about 3-5 years. The second type of GRC installation is to use electric welding connection or expansion bolt conn...

Problems solved by technology

The first type generally has defects such as severe cracking, shedding, powder removal, fading, easy to mold, corrosion, dust absorption and easy to get dirty.

And there is a short service life, and it needs to be painted again in about 3-5 years

The second type of GRC installation is to use electric welding connection or expansion bolt connection, because there are also common risks of cracks, water seepage, corrosion, and falling off between the wall and the secondary connection. Now it is used in the facade decoration of high-rise or small high-rise buildings. Also used less

The third type of tile or granite wet paste construction, because the tile or granite is pasted vertically, the mud on the upper part of the tile or granite is usually not sufficient, and after a long time, there will be whitening and water seepage, which will directly affect the wall. Decoration, even buildings are corroded, falling off, endangering the safety of pedestrians; although dry-hanging marble is the most spectacular, but its cost is high, when high-rise buildings fall off, it will seriously endanger personal safety, and its seams are corroded by rainwater, easy Cause water seepage in the wall or corrosion of dry-hanging components, causing great safety hazards

All of these have brought real troubles to modern architectural decoration.
