地震灾区援建轻钢结构房屋墙体热桥处理的探讨

陕甘南部交界山区的农村住房在遭受了地震破坏之后,新的援建住房采用了施工速度快的冷弯薄壁轻钢装配式房屋。这种房屋以C型或者U型冷弯薄壁钢龙骨形成整体肋板墙体,并以墙体作为承重结构体系。其墙体构造做法上完全不同于传统的砖砌材料,因此,墙体的热工性能存在明显的热桥效应。针对复合墙体的热桥效应进行了探讨。

Measurements for Wall Thermal Bridge of Cold-Formed Steel Framing House in Earthquake Disaster Area

The rural housing has suffered earthquake damage in southern mountainous areas along the junction of Shaanxi and Gansu Provinces,so the cold-formed light steel prefabricated housing is utilized for reconstruction.The C-type or U-shaped cold-formed steel composed the overall walls,which is constructing as structural system of load-bearing.Its wall structure practice is completely different from the traditional materials of brick,where the significant thermal bridge effect is obvious.
