Construction method of large-span retard-bonded prestress
The invention relates to the field of engineering construction, in particular to a large-span retard-bonded prestress construction method which comprises the steps of prestressed tendon laying, concrete pouring, tensioning and cutting and anchor sealing. According to the retard-bonded prestressed concrete construction technology, pre-stress from non-bonding to bonding between the prestressed tendons and the concrete is achieved through curing of the retard-bonded agent, the requirements of large-span and large-space buildings are met, compared with a traditional bonded pre-stress construction technology, the retard-bonded prestressed concrete construction technology saves the two construction procedures of corrugated pipe burying and grouting, and the retard-bonded prestressed concrete construction technology is simpler and more convenient, and the construction efficiency is improved. The construction process is simple, the operability is higher, the construction quality is easier to control, and the structural performance is more excellent. In the construction process, the construction period is shortened, labor is saved, and the overall economical efficiency is better.
本发明涉及工程施工领域，尤其涉及一种大跨度缓粘结预应力的施工方法，包括步骤预应力筋铺设、混凝土浇筑、张拉和切割封锚。通过缓粘结剂的固化实现预应力筋与混凝土之间从无粘结到有粘结的预应力，在满足大跨度，大空间建筑的需求外，相比传统的有粘结预应力施工技术相比，缓粘结预应力混凝土施工技术节省了埋设波纹管及注浆两道施工工序，更加简便，施工工序简单，可操作性更强，在施工质量更容易控制，结构性能更优越。在施工过程中缩短工期，节省劳动力，总体经济性更好。
