预应力砼结构较普通钢筋筋结构不仅用料省,且使用性能好,但其施瓜工艺复杂,技术要求甚高,在一定程度上阻碍了预应力的进一步发展和推广应用。为简化预应力砼的施工工艺人们曾进行多方面的努力,预弯复合梁即是其中之一,现经过近几年的施工经验,现通过试验,将其在施工中应注意的一些情况进行个人总结。 The prestressed concrete structure is not only expected to use the material and the performance is better than the ordinary steel bar structure, but its application process is complex and the technical requirements are very high, hinder the further development and popularization and application of the prestress to a certain extent. In order to simplify the construction process of prestressed concrete, people have carried out many efforts. The pre-bent composite beam is one of them. Now after several years of construction experience, we have tried some of the conditions that should be noticed during construction Personal summary.
