Continuously-variable-height-adjusting and force-measuring pot bearing

Abstract

The invention discloses a continuously-variable-height-adjusting and force-measuring pot bearing comprising an upper bearing plate, a polytetrafluoroethylene (PTFE) sliding plate, a height-adjusting lining plate, a height-adjusting support, a cylinder sleeve, a lower bearing plate, a force-measuring system, a pot plug and a rubber plate, wherein a mirror stainless steel plate is welded on the bottom of the upper bearing plate and forms a plane friction pair with the PTFE sliding plate; the PTFE sliding plate is embedded in a groove of the height-adjusting lining plate; the height-adjusting support is matched with the height-adjusting lining plate; the rubber plate is positioned in a cavity formed between the height-adjusting support and the pot plug; the pot plug is positioned in an inner cavity of the cylinder sleeve and forms an enclosed inner cavity with an oil seal, a sealing ring and a retainer ring matched with the sealing ring; and the force-measuring system is fixed to the cylinder sleeve and is communicated with the enclosed inner cavity formed by the pot plug and the cylinder sleeve. The continuously-variable-height-adjusting and force-measuring pot bearing can be used as a bearing for bridges, buildings or other engineering structures, and can be used as a component for adjusting the elevation of superstructures or replacing substructures which are settled, while also monitoring and measuring various vertical loads of structures.

Description

technical field [0001] The invention relates to a support capable of realizing stepless height adjustment and real-time monitoring of various loads in the vertical direction of structures; specifically, a stepless height adjustment force-measuring basin type support. Background technique [0002] With the continuous development of my country's scientific and technological level, the span of bridge structure is getting larger and larger, the structural forms are more and more, and the functional requirements are gradually increasing. The common point of these long-span complex structure bridges is that they all belong to high-order hyperstatically indeterminate structures, and their internal force calculations are extremely complicated. At the same time, after the bridge is completed, the abutment may settle within a certain period of time, which will cause the redistribution of the internal force of the bridge structure, which will have a catastrophic effect on the high-spee...

Problems solved by technology

However, the rubber plate has become a key part of the entire support. It is necessary to ensure that the rubber plate does not leak oil during use, and it must also have the function of an ordinary rubber support. Therefore, this solution has the disadvantages of easy leakage and small application range. At the same time It is also unable to solve the settlement problem of bridge piers
