Problems solved by technology

However, for bridge supports with different functions, the disadvantage of the existing technology is that the friction pair materials used can only provide a single friction coefficient, which cannot meet the requirements of various supports for the friction coefficient
When the above invention is used as the friction pair material of the bridge support, the overall friction coefficient of the support is expressed as the friction coefficient between ultra-high molecular weight polyethylene or polytetrafluoroethylene and the opposing grinding surface. The friction coefficient is limited by the material of the friction pair and cannot be adjusted. The friction coefficient Relatively simple

Abstract

A composite skeleton structure slide plate for bridge supports, a composite skeleton structure slide plate prepared by three-dimensional compounding of two or more materials, used in bridge supports to meet the different friction coefficients during actual use need.

Description

technical field [0001] The invention belongs to the technical field of composite modification of polymer materials, and in particular relates to a slide plate with composite skeleton structure used for bridge supports. Background technique [0002] Bridge bearings are an important part of bridge structures. The bearing friction pair material is an important part of the bridge bearing to realize the sliding and rotating functions, and it is also a key component that affects the service life of the bridge bearing. With the development of bridge construction in our country, the design and functional subdivision of bridge bearings tend to be more reasonable. For bridge bearings with different functions, different friction coefficients are often required in the design. For example, ordinary spherical bearings require a small friction coefficient, while shock-absorbing and isolating bearings require a relatively large friction coefficient. However, for bridge supports with diffe...
