Friction type damping device for connecting and separating main beams
The invention relates to a friction type damping device for connecting and separating main beams, which is mounted between two adjacent separating type steel box beams and comprises a movable steel pressing plate, a fixed steel pressing plate, a friction plate, a first connecting steel plate and a second connecting steel plate, and the first connecting steel plate and the second connecting steel plate are mounted on the two separating type steel box beams respectively. One end of the movable steel pressing plate is rotatably connected with the first connecting steel plate, one end of the fixed steel pressing plate is fixedly connected with the second connecting steel plate, the ends, close to each other, of the movable steel pressing plate and the fixed steel pressing plate coincide with each other, and the friction plate is located at the coincidence position of the movable steel pressing plate and the fixed steel pressing plate. The movable steel pressing plate, the fixed steel pressing plate and the friction plate are connected with one another through prepressing bolts. Compared with the prior art, the device can play a role when the steel box girders move in the vertical direction and the transverse direction, the movable steel pressing plate and the fixed steel pressing plate which are connected between the two separated steel box girders generate dislocation, the friction plates between the movable steel pressing plate and the fixed steel pressing plate are rubbed, and vortex-induced vibration of the separated steel box girders is effectively reduced.
本发明涉及一种连接分离主梁的摩擦型阻尼装置，安装在相邻的两个分离式钢箱梁之间，包括活动钢压板、固定钢压板、摩擦板以及分别安装在两个分离式钢箱梁上的第一连接钢板和第二连接钢板，活动钢压板的一端可转动连接第一连接钢板，固定钢压板的一端固定连接第二连接钢板，活动钢压板和固定钢压板相互靠近的一端相互重合，摩擦板位于活动钢压板和固定钢压板的重合处，活动钢压板、固定钢压板和摩擦板通过预压螺栓相互连接。与现有技术相比，本发明能够在钢箱梁发生垂直方向以及横向位移时，发挥作用，由连接在两个分离式钢箱梁之间的活动钢压板和固定钢压板产生错动，其间的摩擦板受到摩擦，有效减小了分离式钢箱梁的涡激振动。
