WANG YAO / WANG PEIXIN / YANG SHUO / GE SHANSHAN / ZHOU YONG

The invention discloses a prefabricated concrete composite beam and a construction method thereof. The prefabricated concrete composite beam comprises a supporting beam, wherein a fixing mechanism is arranged on the supporting beam, the fixing mechanism comprises a fixing plate, a first butt-joint reinforcing steel bar, a second butt-joint reinforcing steel bar and fixing parts, the fixing plate is fixedly connected to the top of the supporting beam, the first butt-joint reinforcing steel bar and the second butt-joint reinforcing steel bar are fixedly connected to the two sides of the fixing plate correspondingly, the two fixing parts are arranged in the fixing plate, a stabilizing mechanism is in butt joint with the butt-joint block through the first butt-joint reinforcing steel bar and the second butt-joint reinforcing steel bar and then extrudes a moving block through a rotating bolt, the moving block is pushed to fix the first butt-joint reinforcing steel bar and the second butt-joint reinforcing steel bar, then the connecting tightness between two composite beams is improved through butt joint of supporting rods, fixed rods and transverse rods, and the space formed between the two composite beams can be poured through butt joint between the supporting beams and fixing between the composite beams through supporting blocks, and the working efficiency of workers is improved.

本发明公开了一种预制混凝土组合梁及其施工方法，包括支撑梁，支撑梁上设置有固定机构，固定机构包括固定板、第一对接钢筋、第二对接钢筋和固定部件，固定板固定连接于支撑梁的顶部，第一对接钢筋和第二对接钢筋分别固定连接于固定板的两侧，两组固定部件均设置于固定板内，稳定机构，通过第一对接钢筋和第二对接钢筋与对接块的对接，再通过转动螺栓挤压移动块，推动移动块对第一对接钢筋和第二对接钢筋进行固定，再通过支撑杆与固定杆和横杆之间的对接，增加两个组合梁之间连接的紧密性，通过支撑梁之间的对接，加之支撑块的对组合梁之间的固定，可对两个组合梁之间形成的空间进行浇筑，增加了工作人员的工作效率。
