Problems solved by technology

When the exposed height of the wear-resistant material layer of the support is exhausted due to wear and creep, the friction between the steel plates will occur, and the friction coefficient and reaction force will increase sharply, which will seriously affect the bending and temperature displacement of the bridge, reducing the bridge and Service life of bridge piers

Embodiment Construction

[0020] The structure and working principle of a novel bridge support provided by the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0021] Such as figure 1 Shown is a schematic structural view of the spherical bridge bearing in the novel bridge bearing provided by the present invention. The structure constituting the spherical bridge bearing includes the upper bearing plate 1, the lower bearing plate 4, which can be fixedly connected with the bridge beam body and the bridge pier through the upper and lower anchor components 2 and 3, and the bottom sandwiched between them is Spherical structure intermediate liner 5, the above-mentioned lower support plate is provided with a spherical groove corresponding to the above-mentioned spherical structure; a plane wear-resistant plate 6 is arranged between the above-mentioned upper support plate and the intermediate liner, the plane wear-resistant The grinding plate is clamp...

Abstract

The invention belongs to the technical field of bridge supports, and in particular relates to a novel bridge support. Its main technical solution: its structure is composed of upper and lower support plates which can be fixedly connected with the bridge girder body and pier respectively, and an intermediate liner sandwiched between them; wherein, the upper support plate and the intermediate liner A plane wear-resistant plate made of high molecular weight polyethylene or polytetrafluoroethylene is arranged between the plates; the plane wear-resistant plate is clamped and fixed by a plane wear-resistant clasp fixed on the intermediate liner. The novel bridge bearing has the characteristics of simple structure, improved friction height and durability of the wear-resistant plate.

Description

technical field [0001] The invention belongs to the technical field of bridge supports, and in particular relates to a novel bridge support, which is used to increase the durability of the bridge support so as to prolong its service life. Background technique [0002] The bridge support is set between the bridge and the bridge pier, and is an important connecting part that fixes the beam structure to the bridge pier. It can not only transmit the load on the upper part of the bridge, but also adjust and adapt to the rotation angle and relative displacement of the beam structure. [0003] The wear-resistant material layer between the upper and lower bearing plates and the middle lining plate that constitutes the bridge bearing is a crucial sliding part in the bearing. The wear-resistant material layer plays two roles: one is to use its vertical Rigidity and elastic deformation, transfer the support reaction force of the bridge deck to the pier, and bear the vertical load; the ...
