Embodiment 1

[0022] Such as figure 1 As shown, an overload yielding wind-resistant support includes a steel basin 5, a pressure bearing plate 6, an intermediate steel plate 7, a support adjustment ring 3, and a flat steel plate 1 arranged sequentially from top to bottom. The pressing plate 6 and the middle steel plate 7 are fixed to each other. The middle steel plate 7 is sleeved in the support adjustment ring 3, and the middle steel plate 7 moves up and down along the support adjustment ring 3. The connection between the support adjustment ring 3 and the plane steel plate 1 A plane wear-resistant slide plate 2 is connected on the surface, an internal thread is provided on the inner wall of the support adjustment ring 3, and a corresponding external thread is provided on the outside of the middle steel plate 7.

[0023] The setting of this embodiment overcomes the problem that the installation size of the support in the prior art cannot adapt to the errors existing in the construction. The...

Embodiment 2

[0025] Further optimization is made on the basis of the overload yielding wind-resistant support described in Example 1. A copper sealing ring 4 is provided at the joint between the steel basin 5 and the side wall of the pressure bearing plate 6, which has good sealing performance.

Embodiment 3

[0027] Further optimization is carried out on the basis of an overload yielding wind-resistant bearing described in Embodiment 1 or 2. The material of the pressure bearing plate 6 is rubber, which is easy to find, low in cost, and can play a role in cushioning and shock absorption. effect.

Abstract

The invention discloses an overloading yield type wind-resistant support and belongs to the technical field of bridges. The overloading yield type wind-resistant support comprises a planar steel plate, a supporting adjusting ring which is provided with a trapezoidal thread on the inner side and comprises a planar abrasion-resistant sliding plate, a steel sealing ring, a steel pot, a pressure bearing rubber (polyurethane) plate, a middle steel plate provided with a trapezoidal thread on the outer side, a pressing plate and pressing plate bolts. Under the normal working condition or E1 earthquake working condition, the force transferring path of the support is the steel pot, the pressure bearing rubber (polyurethane) plate, the middle steel plate, the supporting adjusting ring and the planar steel plate. Under the E2 earthquake working condition, the trapezoidal threads are cut off, and the force transferring path of the support is the steel pot, the supporting adjusting ring and the planar steel plate.

Description

technical field [0001] The invention relates to the technical field of bridges, in particular to an overload yielding wind-resistant bearing. Background technique [0002] Wind-resistant bearings are generally used in cable-stayed bridges or suspension bridges. They are installed between towers and bridges. On the one hand, they can transmit horizontal force and fix the bridge; on the other hand, they can prevent the bridge from consolidating with the towers. The wind-resistant support is installed between the bridge tower and the bridge, and it can usually be installed at a later stage. Due to construction errors, the installation size of the existing support is often fixed and cannot adapt to the errors in the construction. [0003] For areas with low seismic intensity, the bridge structure can easily meet the transmission of horizontal forces. But for high-intensity earthquake areas, to meet the force transmission, one solution is to increase the size of the structure, t...
