【正文】 mal insulation technology applies not only to new construction, also apply to the transformation of old buildings, applicable to a wide range, with high technical content。 external insulation package in the main structure of the lateral, to protect the main structure, prolongs the service life of buildings。 effectively reduces the thermal bridges in building construction, increase the construction of effective space。 while eliminating condensation, improve the living fort. (1) external external thermal insulation external insulation materials of rock ( ore) cotton, glass cotton Mat, polystyrene foam board ( referred to as polystyrene board, EPS, XPS ), ceramisite concrete posite polystyrene insulation board, stone decorative wire mesh frame sandwich wallboard. The polystyrene board has excellent physical properties and cheap cost, already all over the world within the external wall insulation plug technology is widely used in. The plugin technology is the use of adhesive mortar or special fasteners, thermal insulation material affixed hanging on the wall, then wipe the anticracking mortar, press glass fiber grid cloth to form a protective layer, finally bined with decorative surface. This type of external insulation installation is timeconsuming, difficult construction, and the construction period to be occupied dominant, main body after the inspection to construction. In the 煙 臺(tái) 大 學(xué) 畢 業(yè) 設(shè) 計(jì) 3 highrise construction, the safety of construction personnel is not easy to be guaranteed. (2) polystyrene plate wall of a casting molding The technique is in the concrete frame shear wall system the polyphenyl board built in building templates, in the gating of the wall outside, then pouring the concrete, concrete and polystyrene board in a casting molding for posite wall. The technology to solve the external insulation problems, its advantage is very obvious. Because the outer wall body with insulation layer of a survival, efficiency, significantly shortening the construction period, and the construction personnel safety assured. But when construction in winter, polystyrene board insulation effect, can reduce the peripheral wall heat preservation measures. But in the concrete to uniform, continuous casting, or because the concrete lateral pressure effect will cause the polystyrene board in Chaimo after deformation and staggered stubble, affect the order of the construction. All kinds of insulation technology and advantages 1, expanded polystyrene board and thin plastering and reinforced by glass fiber approach and advantages It is currently in use in our country most one kind of external insulation wall, wherein the polystyrene board in the primary wall fixed in one of three ways:1) by bonding mortar fixed。2) using a mechanical fixture fixed。3) more than two kinds of fixed bination. This approach has the following advantages:1) because it is in Europe and the United States have been in use for nearly thirty years, in the United States have built high up to 44 layers, therefore. This technology already formed a system, the bonding layer, heatinsulating layer and facing layer supporting the use, more mature technical documents。2) due to the expanded polystyrene insulation materials, the price is very expensive, so that the whole system of moderate price. Convenient user acceptance。3) no plex construction technology, construction unit after a brief training, can grasp the essentials for construction, technology promotion。4) it set insulation, waterproofing and decoration function in a body, has the advantages of multiple functions。5) the whole system has good weatherability, good waterproof and water vapor permeability。6) a variety of color and texture of the surface coating for selection, and the entire system supporting the use of. At present. This approach in Beijing, Northeast China and other places has been widely applied, Beijing Yu Garden, Wolong garden, the Ministry of construction of C eight, C ten buildings transformation and many other engineering, have adopted this approach. However, due to expansion polystyrene against termites, termite in areas not available。 due to the construction of environmental
