【正文】 uction 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。s building energy consumption per unit area is still a climate similar to the developed countries 3 times to 5 times. Construction energy conservation is China39。 partial 39。 JGJ2695as a mandatory standard, at the same time, the Ministry of construction and was released in October 1, 2020seventysixth called regulation of civil building energy saving, do not conform to the standard of energy saving project, shall not approved for construction. In such a series of energysaving policies, regulations, standards and mandatory guidance, China39。s construction industry is an important task. One, external wall thermal insulation technology Energy saving thermal insulation wall construction technology mainly divided into exterior wall internal insulation and exterior wall insulation in two categories. 1internal insulation technology and its characteristics. Within the external wall insulation construction, in the exterior wall structure with internal heat insulation layer. 煙 臺 大 學(xué) 畢 業(yè) 設(shè) 計(jì) 2 Thermal insulation in the construction speed is fast, convenient and flexible operation, can ensure the construction progress. Internal insulation application time is long, the technology is mature, construction technology and inspection standard is perfect. In 2020the construction of external wall insulation in about 90% of the engineering application of internal insulation technology. To be popularized in large area of internal insulation technology : reinforced gypsum posite polystyrene insulation board, polymer mortar posite polystyrene insulation board, reinforced cement posite polystyrene insulation panels, interior wall decoration with polystyrene board plastering gypsum and wipe with particles of polystyrene insulation slurry and anticrack mortar is pressed into the mesh approach. But the internal insulation will occupy the area of use, bridge is not easy to solve, easy to crack, but also affects the construction speed, influence dweller decoration two, and the inner wall hanging and fixing it easy to break the internal insulation structure. Internal insulation technology of irrationality, it would be replaced by external insulation. 2external insulation technology and its characteristics. External insulation is currently promoting a building energysaving insulation technology. The outer and inner thermal insulation, reasonable technology, has its obvious advantages, the use of the same specification, the same size and insulation material, insulation than the inner heat preservation effect is good. External thermal 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。2) using a mechanical fixture fixed。4) it set insulation, waterproofing and decoration function in a body, has the advantages of multiple functions。2) due to the inner layer of the [ knife hole structure. So it has good humidity resistance, in the humid environment, can keep good thermal insulation properties。4) the lateral hanging wire, finishes available tiles. At present, this system is mainly used for castinplace concrete, highrise residential, its construction, installation technology has yet to be further improved. A 4 insulation paste material for exterior wall thermal insulation In recent years, insulation paste is also beginning to be used in building outer wall heat preservation. The utility model has the advantages of:1) insulation paste adhesive layer, insulating l
