Problems solved by technology

Therefore, this existing fluid damper cannot meet the requirements of allowing relative movement under low-speed loads and locking movement under high-speed loads, so it cannot be applied to the bridge wind-resistant bearing

Embodiment Construction

[0018] like figure 1 As shown, this embodiment includes two speed lockers A and two anchoring devices B, the one anchoring device B is fixed on the inner side of the cable-stayed bridge tower C, and the other is fixed on the bridge corresponding to the previous anchoring device On the side of the beam body D, the two ends of the speed locker A are respectively hinged on the two anchoring devices B. The arrangement of the two adjacent speed lockers between the anchorage device on the inner side of the cable-stayed bridge tower C and the anchorage device on the side of the bridge girder body D is a quadrilateral, and the base angle of the quadrilateral is less than 90°, so The bottom angle of the quadrilateral is the inner angle between the locking device and the long side. Of course, in this embodiment, the above-mentioned arrangement form can also be a triangle, at this time, figure 1 The upper ends of the two speed lockers A are jointly hinged at the same point on the ancho...

Abstract

The invention provides a speed associated wind-resistant support for a cable stayed bridge, which comprises at least two speed lockers and at least two anchoring devices and is characterized in that: one anchoring device is fixed on the inner side of the cable stayed bridge; the other anchoring device is fixed on the side edge of the bridge body corresponding to the former anchoring device; and two ends of the speed lockers are respectively hinged to the anchoring device on the inner side of the cable stayed bridge and the anchoring device on the side edge of a bridge body. Because the arrangement way of the speed lockers is a triangle or a quadrangle, and the speed lockers lock under the condition of a high speed, the structural stability of the triangle or the quadrangle is exerted, the bridge body and a bridge tower are fixed and the aim of resisting wind is fulfilled; and under the condition of a low speed, because of the characteristics of the speed lockers that the speed lockers can freely retract, the stability of the triangle or the quadrangle is overcome and the bridge body and the bridge tower can move relatively.

Description

technical field [0001] The present invention relates to bridge supports, in particular to a speed-dependent wind-resistant support for cable-stayed bridges, which allows the bridge to move laterally and longitudinally under temperature loads, and the support under strong winds or earthquakes It will be locked to control the horizontal and vertical movement of the bridge. Background technique [0002] As bridge spans become larger, cable-stayed and suspension bridges are gradually becoming the first choice of bridge engineers. However, the larger the span of the bridge, the higher the tower of the cable-stayed bridge, and the longer the locks, the greater the harm of strong winds to the cable-stayed bridge. How to improve the wind resistance capacity of cable-stayed bridges, especially the lateral wind resistance capacity of the girder itself, is a very important issue. [0003] For the wind resistance of cable-stayed bridges, for a long time, people have often installed tw...
