| Abstract: | An oblique roof is a traditional type of roofs.These years an inclined cast-in-situ reinforced concrete roof is adopted mostly.In this text,construction technique and method for an inclined cast-in-situ reinforced concrete roof is demonstrated,including deep design on scaffolding,coordination and solution of problems of reinforced steel bars crowded together by many ways,initiation on two-side form system by remaining horizontal cast trench and closing form according divided sections,and research and carry out the measures of technique and organization on promoting concrete construction performance. |
