Description

Technical Field

[0002] Steel structure sliding bearings are a type of equipment used to support and fix steel structures, usually installed in bridges, building steel beams and other structures. They can provide the necessary support and allow the structure to move when subjected to loads and temperature changes. In general, building structure nodes are divided into consolidation bearings (which can transmit bending moments and shear forces), sliding bearings (which can transmit vertical forces but cannot transmit bending moments and horizontal forces), and hinged bearings (which can transmit vertical forces and horizontal forces but cannot transmit bending moments). In order to meet the functional requirements of structural design, bearings are often designed into the above three types according to needs. Among them, sliding bearings are a more special type.

[0003] For example, the prior art announcement number is CN218346417U, which is a steel structure sliding support. The utility model can achieve a certain degree of relative displacement between the column foot bottom plate and the support base through the polytetrafluoroethylene layer between the column foot bottom plate and the base steel plate, which can effectively release the horizontal longitudinal displacement and deformation of the upper steel structure under the action of vertical load, horizontal load and temperature load, and reduce the stress effect of the main component.

[0004] The outer wall of the existing sliding support is directly exposed. After long-term use, dust in the outside air will clog the structure inside the sliding support, which will affect the use of the sliding support. In addition, the sliding support cannot transmit only vertical constraints while ensuring structural safety. Based on this, the utility model provides a steel structure sliding support that can only transmit vertical constraints. Utility Model Content
