摘　　要：目的研究龙骨腹板开孔对开孔龙骨复合墙体热工性能的影响,以便为其在我国严寒地区使用时提供设计参考.方法通过标定热箱法对其进行试验,测得墙体的传热系数K,研究龙骨厚度、腹板开孔参数及龙骨间距对开孔龙骨复合墙体保温性能的影响.结果建议在实际工程中,龙骨腹板高度可根据实际需要进行取值,开孔排数取5~7排,开孔长度取为70~80 mm,开孔横向间距取为6~8 mm,龙骨厚度取为1 mm,龙骨间距取为600 mm.结论龙骨腹板开孔可有效减小热桥效应,提高开孔龙骨复合墙体的保温性能.In order to study the influence of the web-perforated on the thermal performance of slotted light steel-framed composite wall,so as to provide a design reference for its use in cold regions of China.The heat transfer coefficient K of the wall was measured by calibrating the hot box method,and the effects of stud metal thickness,perforated parameters of the stud web and stud spacing on thermal insulation performance of slotted light steel-framed composite wall were studied.The relationship between the wall heat transfer coefficient and each parameter is obtained through analysis,and reasonable suggestions are given.It is recommended that in actual engineering,the web height of stud can be determined according to actual needs,rows of slots are 5~7 rows,the length of slots is 70~80 mm,and the distance between slots in the transverse direction is 6~8 mm,the stud metal thickness is 1 mm and the stud spacing is 600 mm.Web-perforated can effectively reduce the thermal bridge effect and improve the thermal insulation performance of slotted light steel-framed composite wall.
