摘要
有黏结预应力混凝土技术最近几年多应用于大跨度、大空间建筑中。有黏结预应力技术可以解决大跨度混凝土梁的挠度和抗裂问题,同时也大大减小混凝土梁的截面尺寸和混凝土及钢筋的用量,提高了结构的使用空间,降低了工程造价。文章结合实际工程介绍了后张有黏结预应力混凝土梁的施工工艺和质量控制措施,为施工人员掌握后张有黏结预应力混凝土梁施工技术提供了参考。
The technique of cohesive prestressed concrete is often used in large-span and large-space architectures in recent years.It solves the deflection and crack problems of large-span concrete beam,and greatly reduces the section size of the concrete beam and the consumption amount of concrete and steel,which makes the service space of the structure improved and the cost reduced.The construction technique and quality control measures of post-tensioned cohesive prestressed concrete beam are discussed in this paper based on the construction projects,and the results can provide references for the engineers involved.
