Assembly type end bearing plate of perforated plate connecting piece combination beam

XU YANGMING

The invention discloses a perforated plate connecting piece combination beam assembly type end bearing plate which comprises a working system composed of pressure-bearing steel plates on the two sides and long bolts, and the pressure-bearing steel plates on the two sides are provided with glue injection channels correspondingly so that effective connection of the pressure-bearing steel plates and perforated steel plates can be achieved; the pressure-bearing steel plates on the left side and the right side are connected through long tenons, so that connection failure of the pressure-bearing steel plates and the perforated steel plates caused by bending moment is prevented; the pressure-bearing steel plates on the left side and the right side are connected through long bolts so that disassembly and repositioning can be facilitated, and the purpose of accurate positioning in the working process is achieved. The device is suitable for the perforated plate connecting piece composite beam, the concrete end bearing effect can be effectively improved by adopting the novel device, and the shear bearing capacity of the perforated plate connecting piece composite beam is improved; by adopting the novel device, the number of welding seams and the number of holes of the perforated steel plate can be effectively reduced, and the anti-fatigue performance of the perforated plate connecting piece composite beam is improved.

本发明公开了开孔板连接件组合梁装配式端承板，包括了两侧的承压钢板及长螺栓组成的工作系统，两侧的承压钢板分别设置注胶通道，以实现承压钢板与开孔钢板的有效连接；左、右两侧的承压钢板设置长榫连接，以防止由弯矩引起承压钢板与开孔钢板的连接失效；左、右两侧的承压钢板采用长螺栓连接，以便于拆卸重新定位，实现工作时准确定位的目的。本发明适用于开孔板连接件组合梁，采用该新型装置可以有效的提高混凝土端承效应，提高开孔板连接件组合梁的抗剪承载力；采用该新型装置可以有效减少焊缝数量及开孔钢板的开孔数量，提高开孔板连接件组合梁的抗疲劳性能。
