Overturn-preventing device and method for small box girder boundary beam of prefabricated anti-collision wall
The invention discloses an anti-overturning device and method for a prefabricated anti-collision wall small box girder boundary beam. The anti-overturning device comprises a pull lug (1), a hanging ring (2), a connecting plate (3) and a pull rod (4). The pull lug (1) is installed on the cover beam (5) in an embedded mode, the upper end of the pull lug (1) forms an annular structure above the cover beam (5), the lower end of the hanging ring (2) is connected with the pull lug (1) through the annular structure, and the upper end of the hanging ring (2) is fixedly connected with the connecting plate (3). The lower end of the pull rod (4) is fixedly connected with the connecting plate (3), and the upper end of the pull rod (4) is adjustably connected with the box girder (6), so that the anti-overturning device is rigidly tied between the cover beam (5) and the box girder (6). On the basis of not influencing the structural performance of the box girder and the cover beam and the subsequent construction operation, rigid pulling connection is formed between the box girder boundary beam and the cover beam top, and the box girder is effectively prevented from overturning due to the bias pressure weight of the anti-collision wall.
本发明公开了一种预制防撞墙小箱梁边梁的防倾覆装置及方法，该防倾覆装置包括拉耳(1)、吊环(2)、连接板(3)和拉杆(4)；拉耳(1)预埋安装在盖梁(5)上，拉耳(1)的上端在盖梁(5)上方形成环状结构，使吊环(2)的下端通过该环状结构与拉耳(1)连接，吊环(2)的上端与连接板(3)固定连接；拉杆(4)的下端与连接板(3)固定连接，拉杆(4)的上端与箱梁(6)可调节式连接，使防倾覆装置刚性拉结在盖梁(5)与箱梁(6)之间。本发明能在不影响箱梁和盖梁结构性能和后续施工作业的基础上，在箱梁边梁与盖梁梁顶之间形成刚性拉结，有效防止箱梁由于防撞墙偏压重量而倾覆。
