Thin-bottom prestressed concrete superposed beam
The invention discloses a thin-bottom prestressed concrete superposed beam. The thin-bottom prestressed concrete superposed beam comprises 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. According to the thin-bottom prestressed concrete superposed beam, in the assembling production process of the thin-bottom prestressed concrete superposed beam, the operation process is simple and convenient, and factory manufacturing is easy to achieve; in the on-site construction process, the common steel bars are laid on a prefabricated bottom plate and anchored into a column or a beam according to anti-seismic specifications, then the prestressed longitudinal steel bars are laid and anchored into the column, and finally the prestressed longitudinal steel bars, the plate and the column can be connected into a whole in a cast-in-place mode. According to the thin-bottom prestressed concrete superposed beam, the problems that a traditional fabricated building joint is poor in performance, beam-column steel bars of prefabricated parts interfere with one another, and the prestressed superposed beam does not have the common steel bars anchored into the column and cannot meet the standard requirement are solved, and the thin-bottom prestressed concrete superposed beam has the advantages of being good in anti-seismic performance and overall performance and the like.
本发明公开了一种薄底预应力混凝土叠合梁，其包括混凝土薄底、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。本发明装置在组装生产过程中，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，预制底板上铺设普通钢筋，普通钢筋按照抗震规范锚固入柱中或梁中，然后铺设预应力纵向钢筋并锚固至柱内，最后可以与板、柱现浇连接成为一个整体，避免了传统装配式建筑节点性能差的问题、预制构件梁柱钢筋相互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。
