Thin-bottom groove type prestressed concrete superposed beam
The invention discloses a thin-bottom groove type prestressed concrete superposed beam. The concrete superposed beam comprises a concrete side wall, a concrete thin bottom, prestressed longitudinal steel bars, a plurality of stirrups and common steel bars, and the stirrups are equidistantly arranged along the same straight line. In the production process, the operation process is simple and convenient, and factory-like manufacturing is easy to achieve; in the on-site construction process, the common steel bars are laid on the concrete thin bottom and anchored into a column or a beam according to the anti-seismic specification, then upper longitudinal bars are laid and anchored into the column, and finally the upper longitudinal bars, plates and the column can be connected into a whole in a cast-in-place mode, so that joint stress of the later-laid steel bars and a prefabricated part can be achieved; and the problems that a traditional fabricated building joint is poor in performance, beam column reinforcing steel bar interference of the prefabricated part and a prestressed superposed beam does not meet the standard requirement due to the fact that no common steel bar is anchored into the column are solved, and the advantages of being good in anti-seismic performance and overall performance and the like are achieved.
本发明公开了一种薄底槽型预应力混凝土叠合梁，其包括混凝土侧壁、混凝土薄底、预应力纵向钢筋、箍筋以及普通钢筋，所述箍筋设置有若干个，且若干个所述箍筋沿同一条直线等距排列。本发明在生产过程中，操作流程较为简单、便捷，容易实现工厂化制作；在现场施工过程中，混凝土薄底上铺设普通钢筋，普通钢筋按照抗震规范锚固入柱中或梁中，然后铺设上部纵筋并锚固至柱内，最后可以与板、柱现浇连接成为一个整体，可以实现后铺钢筋同预制构件共同受力，避免了传统装配式建筑节点性能差的问题、预制构件梁柱钢筋干扰问题和预应力叠合梁无普通钢筋锚固至柱内而不满足规范要求的问题，具有抗震性和整体性能好等优点。
