Secondary beam structure for assembly type self-bearing prestressed floor slab
A secondary beam structure for a fabricated self-bearing prestressed floor slab comprises two end beams arranged at the two transverse ends in parallel and two longitudinal secondary beams arranged at the two longitudinal sides in parallel, and the end beams at the two ends intersect with the longitudinal secondary beams on the two sides at end points. Longitudinal prestressed steel bars are arranged in the lower portions of the longitudinal secondary beams and penetrate through the end beams, at least one longitudinal middle rib parallel to the longitudinal secondary beams is arranged between the two longitudinal secondary beams, and the two ends of the longitudinal middle rib are connected with the two end beams respectively. At least one transverse rib crossed with the longitudinal middle rib is further arranged between the two end beams, the transverse rib perpendicularly intersects with the longitudinal secondary beam, the end beams, the longitudinal secondary beam, the longitudinal middle rib and the transverse rib jointly form a force bearing framework, a concrete upper plate integrally formed with the framework is arranged on the upper portion of the force bearing framework, and a concrete lower plate integrally formed with the framework is arranged on the lower portion of the concrete upper plate. The whole framework is covered with the concrete upper plate, the lower portions of the longitudinal outer sides of the longitudinal secondary beams protrude outwards to form lower outer flange structures, the bottoms of the lower outer flange structures are flush with the bottoms of the longitudinal secondary beams, and the large-span framework has the advantages that high formwork erecting is avoided, and the large-span requirement is met.
一种用于装配式自承力预应力楼板的次梁结构，所述的次梁结构包括两条平行设置在横向两端的端部梁、两条平行设置在纵向两侧的纵向次梁，两端的端部梁与两侧的纵向次梁在端点相交，所述的纵向次梁的下部中设置有纵向预应力钢筋，纵向预应力钢筋穿过端部梁，在两条所述的纵向次梁之间设置有至少一条与纵向次梁平行的纵向中肋，纵向中肋两端分别连接两条端部梁，同时在两条所述的端部梁中间还设置有至少一条与纵向中肋十字相交的横肋，且横肋垂直相交于纵向次梁，所述的端部梁、纵向次梁、纵向中肋和横肋共同构成承力骨架，所述的承力骨架上部设置有与骨架一体成型的混凝土上板，混凝土上板覆盖整个骨架，所述纵向次梁的纵向外侧下部向外凸出，形成下外翼缘构造，所述下外翼缘构造的底部与纵向次梁底部齐平，具有免高支模，实现大跨度的需求等特点。
