Construction method of external wall thermal insulation building structure introduction of external wall thermal insulation materials

There are two kinds of cold now, one is the cold in the south and the other is the biting cold wind in the north. It is necessary to make thermal insulation structure for the external walls of some buildings in the north, which can not only beautify the buildings, but also take into account the thermal insulation of the internal walls. So what is the construction scheme of the external thermal insulation building structure? Let's take you to know what the relevant knowledge is.

A, the construction method of external thermal insulation building structure

1. With polystyrene board as thermal insulation material, polymer bonding mortar as bonding material, polymer gypsum mortar as decorative layer, alkali-resistant glass fiber plastic-coated grid cloth as supplementary wall, it is fixed with fastening nails to realize the construction and acceptance of external thermal insulation system of private buildings.

2. Product material requirements: the technical performance of all materials used for external wall insulation construction must meet the relevant national standards.

3. Requirements of construction personnel: Establish a construction team according to the project scale and schedule requirements. Before construction, the construction personnel should be trained to ensure the quality and progress of the construction project from the aspects of ideology, technology, quality and safety.

Second, the introduction of external wall thermal insulation materials

1. Inorganic active exterior wall insulation materials, rubber powder polystyrene particles, silicate insulation materials, steel wire mesh cement foam board (Shule board), extruded board XPS, rigid foam polyurethane exterior wall spraying, ceramic insulation materials, rigid polyurethane spraying foam, EPS foam board, rigid foam polyurethane insulation board, foamed cement.

2.EPS board refers to the expanded polystyrene board made of expanded polystyrene material after pretreatment, hardening, molding, drying and cutting. This kind of external wall thermal insulation material can be made of foam plastic products with different thicknesses, shapes, densities and shapes.

3. Phenolic foam. Phenolic foam is an internationally recognized construction team dedicated to developing new external wall insulation materials. The external wall insulation layer does not burn, melt or emit toxic gas when it meets fire, and has the advantages of light weight, non-toxicity, non-corrosion, heat insulation, energy saving, sound insulation and low price.

4.XPS extruded board, polystyrene board and gypsum external wall have the characteristics of thermal insulation, high strength, excellent thermal insulation performance and excellent air permeability. It is a kind of thermal insulation system, which is widely used in construction projects with high thermal insulation requirements, such as frozen areas, real estate, refrigeration projects and so on.

5. The external wall insulation net is made of medium-alkali or alkali-free glass fiber net, woven into glass fiber net as base material, coated with acrylic polymer solution and dried. Alkaline new products. This product has the advantages of stable structure, high strength, alkali resistance, corrosion resistance, crack resistance, reinforcement, simple structure and easy implementation, and is a new building material for external wall insulation engineering.

6. Rock wool board refers to mineral fibers mainly made of natural rocks, which are melted at high temperature and mixed with a certain proportion of adhesives and additives. Water-containing insulation board and rock wool insulation material are the second largest insulation materials in Europe after polystyrene insulation materials, which are mainly used in high-rise buildings with high fire protection requirements.

The above is a detailed introduction of the construction method of external wall thermal insulation building structure and the introduction of external wall thermal insulation materials. In this small series, it is suggested that some buildings should not do external insulation, such as ice storage and some cold storage facilities, which have extremely low temperature requirements and should choose suitable materials according to the characteristics of buildings.
