Double-breadth separation continuous beam bridge anti-overturning device and anti-overturning method
The invention discloses an anti-overturning device and an anti-overturning method for a double-amplitude separation continuous beam bridge, the device comprises a rod piece system, the rod piece system comprises a horizontal rod and an inclined rod, one end of the horizontal rod is connected with the side face of one main beam of the separation continuous beam bridge, and the other end of the horizontal rod is connected with the other main beam of the separation continuous beam bridge; one end of the inclined rod is connected with the side face of one main beam of the separated continuous beam bridge, and the other end of the inclined rod is connected with the other main beam of the separated continuous beam bridge; the horizontal rod is parallel to the surface of the main beam, and the inclined rod and the surface of the main beam are obliquely arranged. The transverse connection structure is arranged between the two bridges, under the condition that the stress states of the two bridges are not changed and the operation characteristics of the bridges are not changed, rigid overturning of the main beam is prevented, the moment is formed by utilizing the weight of the other bridge to resist the overturning moment, and therefore the overturning moment is prevented. Under the action of normal loads such as live loads, temperature loads and automobile braking force, the stress state of the main beam is not changed.
本发明公开了一种双幅分离连续梁桥抗倾覆装置及抗倾覆方法，装置包括杆件系统，杆件系统包括水平杆和斜杆，水平杆的一端和分离连续梁桥的一个主梁的侧面相连接，另一端和分离连续梁桥的另一个主梁相连接；斜杆的一端和分离连续梁桥的一个主梁的侧面相连接，另一端和分离连续梁桥的另一个主梁相连接；水平杆和主梁梁面相平行，斜杆和主梁梁面倾斜设置。本申请通过在两幅桥梁之间设置横向联系构造，在不改变两幅桥梁各自的受力状态、不改变桥梁运营特征的情况下，实现防止主梁的刚性倾覆，利用利用另外一幅桥的重量形成力矩以抵抗倾覆力矩，在正常荷载如活载、温度荷载、汽车制动力等作用下，主梁受力状态不改变。
