Plate type vibration damping boom

Abstract

The invention provides a plate-type damping suspender and relates to the field of bridges. The plate-type damping suspender comprises a hanger plate and a wind resistance device which are mounted on the hanger plate, and the wind resistance device comprises a fixed plate, a rain diversion edge and a rotation component; the fixed plate is fixed mounted on the hanger plate, the rain diversion edge is mounted on the fixed plate, and the rain diversion edge changes wind field to have rain water diverted so as to reduce wind-induced vibration of the suspender; the rotation component comprises a rotation shaft, a first rotating piece and a second rotating piece; the rotation shaft is connected with the fixed plate, the first rotating piece and the second rotating piece are respectively fixedly mounted on the rotation shaft and can rotate around the rotation shaft respectively to break the even wind field, and meanwhile, the wind-induced vibration of the suspender can be further lowered through rotational energy consumption of the suspender. The plate-type damping suspender is ingenious in structural design, the wind-induced vibration can be lowered through change of the wind field and rotational energy consumption of the suspender, wind resistance is good, and high reliability is achieved; by the arrangement, wind and rain resonance can be effectively prevented, and stability of the suspender is improved.

Description

Technical field [0001] The invention relates to the technical field of bridges, and in particular to a plate-type vibration damping boom. Background technique [0002] Suspension rods are generally used in bridge construction and have been subjected to wind and rain for a long time, and the use environment is harsh, but the suspension rods are important components in the bridge structure. For example, in a suspension bridge, the suspension rod is a rod connecting the suspension cable and the bridge deck system, and the load of the bridge deck system is transmitted to the suspension cable through the suspension rod. With the continuous development of the bridge industry, there are more and more bridges of various types. For example, when the span of a mid-through or through-through arch bridge increases, the length of the boom is longer and more flexible, and the more sensitive it is to wind, the worse its wind resistance stability. [0003] At present, viscoelastic quenched and t...

Problems solved by technology

[0003] At present, viscoelastic modified dampers are generally used as windproof measures for suspenders. However, the viscoelastic modified damper structure itself has poor durability, high engineering cost, and high maintenance costs, so it is difficult to be popularized and applied.
