【正文】 節(jié)能材料的發(fā)展又必須與外墻保溫技術(shù)相結(jié)合 ,才能真正發(fā)揮其作用。 。 能。應(yīng)根據(jù)所設(shè)計(jì)的建筑的造價(jià)、地理位置等各方面的因素進(jìn)行選擇 。冬季可照常施工； 4)聚苯板外側(cè)掛有鋼絲網(wǎng)，外飾面可用面磚。在冬季可照常施工。這種做法在北京、東北等地已得到廣泛的應(yīng)用，北京裕京花園、臥龍花園、建設(shè)部丙八、丙十樓的改造等許多工程，均采用了這種做法。由于外墻主體與保溫層一次成活 ,工效提高 ,工期大大縮短 ,且施工人員的安全性得到了保證。 目前比較成熟的外墻保溫技術(shù)主要有以下幾種。內(nèi)保溫在技術(shù)上的不合理性 ,決定了其必然要被外保溫所替代。 一、外墻保溫技術(shù) 節(jié)能保溫墻體施工技術(shù)主要分為外墻內(nèi)保溫和外墻外保溫兩大類。 thermal conductivity than the metallic material。3) suitable for cold insulation on the special requirements of the building, and can also be used for exterior wall facing material for brick or stone building,4) as a result of extruded polystyrene and the base wall fixing mode of soil using mechanical fastener. In winter the normal construction. At present. In Beijing, the river runs and other regions have to use this material for outer wall external thermal insulation construction, such as the Beijing New Oriental Plaza, Bank of China and other large public buildings. But the extruded polystyrene price is on the high side, thus is suitable for higher grade of the building. The construction technology and node structure needs to be further perfected. The 3single side steel mesh polystyrene board with the exterior wall external insulation This is developed in recent years, used for castinplace concrete construction of external wall insulation system, a kind of liu. It has the following advantages:1) this system in the construction of. The steel mesh polystyrene board is arranged to pouring wall inside an external mold, external insulation board and the wall a survival, after stripping the insulation board and the wall be made one, thus saving manpower, time and cost of installation。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。s energysaving housing construction work unceasingly thorough, continuously improve the energy efficiency standards, the introduction of the development of many new energysaving technology and materials, vigorously promote the use of residential buildings. But our country39。s current level of building energy conservation, but also far lower than developed countries, China39。2) due to the expanded polystyrene insulation materials, the price is very expensive, so that the whole system of moderate price. Convenient user acceptance。2) selection of steel mesh polystyrene plate, light weight, easy construction。 gaseous material thermal conductivity less than the liquid material, the liquid material is less than solid. So when conditions permit, should try to use the organic polymer materials or amorphous inorganic material, which is favorable for heat insulation. From the material structure, as the material is apparent density decreased, the porosity increases, the material inside the pores as a substantially enclosed micro hole, coefficient of heat conductivity of the material is relatively small. For foam products, to meet the requirements of thermal insulation materials and the best apparent density of 16~ 40kg / m3. 2 monly used thermal insulation materials. Can meet the performance 煙 臺(tái) 大 學(xué) 畢 業(yè) 設(shè) 計(jì) 6 requirements for exterior insulation energysaving materials are: polystyrene foam board ( EPS and XPS ), rock ( ore) cotton board, glass wool felt and super light particles of polystyrene insulation slurry etc.. All of the above materials are a mon feature of the materials within a closed hole, their apparent density is small, it is also used as insulation materials required. Rock ( ore) wool and glass wool are sometimes referred to as the mineral cotton, which belongs to the field of inorganic material. Rock wool, not bustion, low price, to meet the heat insulation performance but also has a certain sound insulation effect. But the rock quality varied widely, good thermal insulation properties of low density, the tensile strength is low, poor durability. Three, conclusion At present our country external wall thermal
