大模内置外墙保温施工技术在高层建筑中的应用

在建筑施工的过程中,外墙的施工是非常耗费能量的,为了能够更好地保证建筑施工的质量,外墙保温技术在建筑施工中得到了非常广泛的应用。在外墙保温中建筑材料的类型和所选择的施工技艺也对整体的效果产生了非常重要的影响。本文主要分析了大模内置外墙保温施工技术在高层建筑中应用,希望能够给相关的施工人员提供一定的经验和借鉴。

Experimental study on axial compressive behaviors of prefabricated composite thermal insulation walls after single-side fire exposure

The axial bearing capacity of prefabricated composite walls composed of inner and outer concrete wythes,expandable polystyrene(EPS)boards and steel sleeve connectors is investigated.An experimental study on the axial bearing capacity of four prefabricated composite walls after fire treatment is carried out.Two of the prefabricated composite walls are normal-temperature specimens,and the others are treated with fire.The damage modes and crack development are observed,and the axial bearing capacity,lateral deformation of the specimens,and the concrete and reinforcing bar strain are tested.The results show that the ultimate bearing capacity of specimens after a fire is less than that of normal-temperature specimens;when the insulation board thicknesses are 40 mm and 60 mm,the decrease amplitudes are 20.8%and 16.8%,respectively.The maximum lateral deformation of specimens after a fire is greater than that of normal-temperature specimens,and under the same level of load,the lateral deformation increases as the insulation board thickness increases.Moreover,the strain values of the concrete and reinforcing bars of specimens after a fire are greater than those of normal-temperature specimens,and the strain values increase as the thickness of insulation board increases.

倚天·盛世钱塘的“建筑节能”住宅是什么?

[XPS 外墙外保温隔热系统]围合结构外墙的节能,对于建筑节能目标的实现无疑是一项关键措施。在浙江外墙外保温仍然处于起步阶段,所以大家对它的了解不是很多。一般来说,外墙外保温的材料主要有三种,保温效果由差到好依次为高保温砂浆、砂浆聚苯颗粒和聚苯挤塑板。倚天·盛世钱塘采用的美国陶氏化学公司舒泰龙品牌挤塑型聚苯板,是目前外墙外保温材料中节能效果较好的一种。该材料具有极低的稳定的导热系数、极低的吸水率及优异的尺寸稳定性,再加上无表皮的毛面特色,确保了系统稳定、优异的热工性能和机械性能。外墙外保温系统即保温材料处于外墙的外侧,由于其具有保温隔热性能优良、消除结构性冷热桥、保护主体结构、不占室内使用面积、不影响室内装修。
