Large-span concrete beam retard-bonded and unbonded prestress comprehensive construction method
The invention discloses a retard-bonded and unbonded prestress comprehensive construction method for a large-span concrete beam. In the invention, the two prestress forms of the retarded-bonding prestressed tendon and the unbonded prestressed tendon are similar in structure and the same in construction process, and by adopting the mode of combining the retarded-bonding prestressed tendon and the unbonded prestressed tendon, the effects of reducing procedures, saving cost, ensuring the construction period and the like can be achieved while the anti-seismic effect is ensured. A large-span concrete beam slow-bonding and non-bonding prestress comprehensive construction technology is applied to a Fuyang Zhengrongfu project, so that the problems that prestress engineering construction is complex and the anti-seismic property is poor are solved. The construction method is suitable for various large stadiums with large-span structures, exhibition centers, indoor weather playgrounds and the like, meets the using functions, is convenient to construct, and further shortens the construction period. Particularly, the anti-seismic requirement of a large-span structure can be met, and objective economic benefits and social benefits are created.
本发明公开了一种大跨度混凝土梁缓粘结与无粘结预应力综合施工方法。本发明中，缓粘结与无粘结预应力筋两种预应力形式构造类似，施工工艺相同，采用两者结合的方式，可以在保证抗震效果的同时，达到减少工序，节约成本，保证工期等效果。在阜阳正荣府项目应用大跨度混凝土梁缓粘结与无粘结预应力综合施工技术，以解决预应力工程施工复杂、抗震性能差的问题。适用于各类大型的、大跨度结构体育场、会展中心、室内风雨操场等，满足其使用功能，施工方便，进一步缩短工期。尤其可以解决大跨度结构的抗震要求，进而创造客观的经济效益及社会效益。
