| Abstract: | The roof beams of frame of some multi-layer workshops in Anyang City are concrete structure of the behind tension curve pre-stressed force. It involves construction technology of working procedure: the curve lofting of corrugated pipes, the steel stranded wire arranged ties, fixing of the corrugated pipes, tension of the steel wires the and so on, at the same time, selected materials with the curve pre-stressed force should be paid attention to. |

| Keywords: | roof beam of frame steel twisted group of lines of the behind tension curve pre - stressed force symmetrical tension of corrugated pipes |
