Reinforced concrete column with prefabricated reinforcement cage and UHPC formwork and construction method
The invention provides a reinforced concrete column with a prefabricated reinforcement cage and a UHPC formwork and a construction method. The reinforced concrete column comprises a reinforcement cage, and the reinforcement cage comprises a plurality of longitudinal bars and a plurality of stirrups hooped on the longitudinal bars at intervals in the longitudinal direction; a plurality of transverse bars and a plurality of UHPC templates are further included; the stirrups are welded on the longitudinal bars; a plurality of transverse bars are welded to each stirrup in the same horizontal direction, and the arrangement directions of the transverse bars on every two adjacent stirrups are different. The length of the transverse bar is greater than the external dimension of the stirrup, and two ends of the transverse bar protrude outwards to form protruding sections; the UHPC formwork is supported on the periphery of the reinforcement cage before initial setting, and the protruding section is inserted into the UHPC formwork; after the UHPC formwork is solidified, concrete is poured into the UHPC formwork; uHPC has the advantages of being high in strength, good in durability, good in impermeability and the like, and the problems of cracking, corrosion and the like of the column can be effectively prevented when the UHPC is used as a permanent formwork of the concrete column; and meanwhile, the UHPC templates on each side are connected in a wet manner, so that the integrality of the templates is better, and the situation of slurry leakage is avoided.
本发明提供了一种预制钢筋笼和UHPC模板的钢筋混凝土柱及施工方法；钢筋混凝土柱包括钢筋笼，其包括多个纵筋、以及沿纵向间隔箍设于纵筋上的多个箍筋；还包括有多个横筋以及多个UHPC模板；箍筋焊接于纵筋上；每个箍筋上沿水平的同一方向焊接有多个横筋，且相邻的两个箍筋上的横筋设置方向不一致；横筋的长度大于箍筋的外尺寸，其两端均向外凸出形成有凸出段；UHPC模板在初凝前支设于钢筋笼外周，凸出段插入UHPC模板中；UHPC模板凝固后，其内浇筑混凝土；UHPC具有强度高、耐久性好及抗渗性好等诸多优点，将其用作混凝土柱的永久性模板可以有效防止柱出现裂缝和腐蚀等问题；同时每一面UHPC模板之间的连接都是湿连接，模板之间的整体性更好，不会出现漏浆的情况。
