Multiple-point bearing pot type rubber support

Abstract

The invention discloses a multiple-point bearing pot type rubber support. The multiple-point bearing pot type rubber support comprises an upper support plate, a lower support base plate, a middle supporting plate, a tetrafluorohydrazine sliding plate, a stainless steel plate, a first rubber mat, a second rubber mat, a third rubber mat and a fourth rubber mat, wherein the middle supporting plate isarranged on the lower support base plate, the first rubber mat, the second rubber mat, the third rubber mat and the fourth rubber mat are arranged between the lower support plate and the middle supporting plate, the tetrafluorohydrazine sliding plate is arranged on the middle supporting plate, and the upper support plate is arranged on the tetrafluorohydrazine sliding plate; the stainless steel plate is arranged between the tetrafluorohydrazine sliding plate and the upper support plate, and the tetrafluorohydrazine sliding plate is slidably connected with the stainless steel plate which is embedded into the upper support plate. According to the multiple-point bearing pot type rubber support, four pot type cavities are formed in the lower support base plate, the rubber mats are arranged inthe four pot type cavities respectively, the middle supporting plate is provided with four supporting feet, the four supporting feet are matched with the rubber mats in the four pot type cavities, and the supporting force borne by the support is uniformly dispersed to the four rubber mats, so that the bearing capacity is higher, and the anti-seismic effect is better.

Description

【Technical field】 [0001] The invention relates to the technical field of bearings, in particular to the technical field of a multi-point load-bearing pot rubber bearing. 【Background technique】 [0002] The bridge support is an important structural component connecting the upper structure and the lower structure of the bridge. It is a device erected on the abutment, and the top surface supports the upper structure of the bridge. The effect of the earthquake must be taken into account when constructing bridges and high-rise buildings in earthquake-prone areas, so that when an earthquake occurs, the bridge and high-rise buildings can maintain their use functions, which is of great benefit to subsequent disaster relief and earthquakes. Post-recovery work is of great significance to reduce losses. The pot rubber bearing is a structural component that connects the bridge superstructure and the pier, transmits loads and meets the requirements of bridge displacement and rotation. Mo...

[0002] The bridge support is an important structural component connecting the upper structure and the lower structure of the bridge. It is a device erected on the abutment and the top surface supports the upper structure of the bridge. Its function is to fix the upper structure to the abutment and bear the various forces acting on the upper structure. The effect of the earthquake must be taken into account when constructing bridges and high-rise buildings in earthquake-prone areas, so that when an earthquake occurs, the bridges and high-rise buildings can maintain their function, which is of great benefit to subsequent disaster relief and earthquakes. Post-recovery work is of great significance to reduce losses. The pot rubber bearing is a structural component that connects the bridge superstructure and the pier, transmits loads and meets the requirements of bridge displacement and rotation. The existing pot rubber bearings are mostly single blocks Rubber structure, limited bearing capacity, unable to disperse the force more evenly, and weak earthquake resistance
