Exterior thermal-insulation and exterior decoration system for external wall and construction method therefor

Abstract

The invention involves a insulating and finishing systems of the outer walls of buildings and its construction methods, particularly a low-cost, durable and safe insulating walls and it's more advanced construction methods. Said aim is achieved by the following technical methods: 1. pretreating the outer walls of buildings to making the outer walls binding with cement tightly. 2. fixing the decorative plate on the disposed walls using the stones dr-hanging technique, said decorative plate includes stone face brick, ceramic face brick and other decorative face brick for walls. The distance between walls and decorative face brick is given by designer. 3. Casting objects into the cavity formed between the outer walls and decorative face brick and reaching the construction requirement, the objects is prepared by mixing the light-weight insulation particles, cement and water. The light-weight insulation particles include polyphenyl foam particles, rock fiber particles, pearlstone particles and other insulating materials which can be processed into particles. The insulating walls constructed according the method has advantages such as the quality is durable and aesthetic, cost is low, process is simple and the construction period is short.

Description

Technical field [0001] The invention relates to a thermal insulation and facing system and a construction method for an external wall of a building, in particular to a low-cost, strong and safe thermal insulation wall, and a more advanced construction method. Background technique [0002] In recent years, my country has vigorously promoted energy-saving buildings and has made great progress in the energy-saving technology of external walls of buildings. At present, wall insulation systems are mainly divided into external wall insulation and wall internal insulation. Wall insulation technology is due to many The unfavorable reason is that the external wall insulation technology has not been promoted and applied, and there are many solutions for external wall insulation technology, the main ones are polystyrene board external sticking, polystyrene board cast-in-place concrete composite, rubber powder polystyrene particles, rigid polyurethane foam and other technologies. These techn...

Problems solved by technology

[0002] In recent years, my country has vigorously promoted energy-saving buildings, and has made great progress in the energy-saving technology of building exterior walls. Now the wall insulation system is mainly divided into wall insulation and wall insulation. Due to many The unfavorable reason is that it is no longer popularized and applied. There are many schemes for the external wall insulation technology, the main ones are polystyrene board external sticking, polystyrene board cast-in-place concrete composite, rubber powder polystyrene particles, rigid polyurethane foam and other technologies. These technologies generally have the following disadvantages: 1. The construction process is complicated

2. Quality control is difficult

3. Long construction period

4. High cost

Due to the existence of these disadvantages, the development of energy-saving wall buildings has been greatly restricted.
