Flexible high-tensile-strength and anti-corrosion integrated shock insulation rubber support

Abstract

The invention discloses a flexible high-tensile-strength and anti-corrosion integrated shock insulation rubber support. Integrated vulcanization anti-corrosion layers are arranged on the faces, facing a support body, of an upper flange plate and a lower flange plate and the side faces of the upper flange plate and the lower flange plate; and a framework plate comprises one or more large-hole framework plate bodies. The large-hole framework plate bodies, conventional framework plate bodies or edge special-shaped framework plate bodies are independently used or used in cooperation, on the premise that the lateral restraint of a steel plate on internal rubber is not weakened, the total thickness of a rubber layer is increased, the vertical compressive rigidity and the vertical bearing force of the shock insulation rubber support cannot be reduced, the horizontal rigidity and the vertical tensile rigidity are further reduced, and the shock insulation efficiency and the tensile capacity of a shock insulation layer are improved. The anti-corrosion capacity of the support can be improved through the arrangement of the integrated anti-corrosion layers, the production process is simplified, and the production cost is reduced.

Problems solved by technology

Constrained by the tight conditions of construction land, buildings are gradually developing to high-rise buildings. Due to the poor tensile performance of seismic isolation rubber bearings, the application of seismic isolation technology in high-rise buildings is limited; as scientific researchers improve their understanding of earthquake mechanisms, The requirements for seismic design of buildings are also gradually increasing, which requires seismic isolation rubber bearings with better tensile properties to resist earthquake overturning; The series or parallel connection of seismic rubber bearings resists the tensile stress together, which can theoretically achieve a better tensile effect, but the series and parallel tensile members and the seismic isolation rubber bearings are often not synchronized when they are subjected to earthquakes. As a result, the theoretical model used in the design process is inconsistent with the actual stress state, so there are certain safety hazards in the seismic isolation structure designed in the form of series or parallel connection of tensile members and seismic isolation rubber bearings; at the same time, the existing seismic isolation The anti-corrosion treatment of rubber bearings is generally brushed or sprayed with rigid anti-rust paint. The brushing or spraying process is easy to pollute the environment. The operation process is relatively complicated, time-consuming and laborious, and it is easy to fall due to collision during the construction process. Manual paint touch-up treatment is required before acceptance, the anti-corrosion effect is average, and integrated anti-corrosion cannot be achieved, and the process is cumbersome
