Description

Technical Field

[0001] The utility model relates to the technical field of rubber bearings, in particular to a bidirectionally movable basin-type rubber bearing for a highway bridge. Background Art

[0002] The pot-type rubber bearing is a new type of bridge bearing composed of steel components and rubber. Compared with other pot-type bearings of the same type and cast steel roller bearings, it has the advantages of large bearing capacity, large horizontal displacement, flexible rotation, etc. The pot-type rubber bearing is composed of an upper seat plate, a sealing ring, a rubber plate, a bottom basin, anchor bolts and a dust cover. It is easy to process and manufacture, saves steel, and reduces the cost. It is an ideal bearing suitable for large-span bridges. The bearing capacity of the bearing is 31 levels, with a bearing capacity of 0.8MN-60MN, which can meet the needs of large bridge construction. In the standard series, the horizontal bearing capacity of the fixed bearing in all directions and the non-slip direction of the unidirectional movable bearing is not less than 10% of the bearing's vertical bearing capacity, and the horizontal bearing capacity of the seismic-resistant bearing is not less than 20% of the bearing's vertical bearing capacity. 01 After silicone grease lubrication, the minimum friction coefficient of the cold-resistant movable bearing is 0.06. The working principle of the pot-type rubber bearing is to use the elastic rubber block in the semi-enclosed steel pot cavity, which has the properties of fluid under the three-way force state, to realize the rotation of the upper structure; at the same time, the low friction coefficient between the polytetrafluoroethylene plate on the middle steel plate and the stainless steel plate on the upper seat plate is used to realize the horizontal displacement of the upper structure. From the experimental data, the compressive elastic modulus of the rubber in the three-way constraint state is 5*104kg / cm2, which is nearly 20 times higher than the compressive elastic modulus without lateral constraint. Therefore, the bearing capacity of the bearing is greatly improved, which solves the limitation of the bearing capacity of ordinary rubber bearings. Therefore, the pot-type rubber bearing is a new product that can meet the requirements of large support reaction force, large horizontal displacement and large rotation angle.

[0003] The currently used unidirectional movable rubber bearings are subject to unidirectional force. When disturbed by other external forces, the rubber bearings are prone to displacement. Large displacements will affect their normal use and pose safety hazards. Therefore, we propose a bidirectional movable pot-type rubber bearing for highway bridges to solve the above problems.
