Problems solved by technology

[0005] The design life of general buildings is 50 years or even more than 50 years, and the rubber in the lead rubber shock-isolation bearing will gradually age, and its service life is less than 50 years. Therefore, within the design life of the building, the lead must be replaced. Core rubber isolation bearings, and the earthquake will also cause damage to the lead rubber isolation bearings, and the lead rubber isolation bearings of the building after the earthquake need to be replaced
However, because the seismic isolation layer of the building is often stressed unevenly, the

Abstract

The invention discloses a lead rubber bearing. The lead rubber bearing comprises a main inside screw thread sleeve (1), an upper pre-buried steel plate (3), an upper connecting steel plate (4), a lead rubber bearing main body (5), a lower connecting steel plate (6), a lower pre-buried steel plate (8), an upper fastener (10), a standby inside screw thread sleeve (11) and main lower fasteners (12), wherein the upper fastener (10) is screwed with an upper buttress (2); a hanging buckle (29) of the upper fastener (10) is locked with the upper connecting steel plate (4); a main protrusion (17) is arranged on the lower pre-buried steel plate (8); a vertical plate (19) of each of the main lower fasteners (12) is screwed with the main protrusion (17); and a pressing plate (20) of each of the main lower fasteners (12) is pressed on the top surface of the lower connecting steel plate (6). The lead rubber bearing is convenient to exchange.

Description

technical field [0001] The invention relates to the field of building shock isolation, in particular to a lead rubber shock-isolation bearing installed in a shock-isolation layer of a building structure. Background technique [0002] Earthquakes can cause massive damage, causing loss of life and economic loss. In order to slow down the disasters caused by earthquakes, people try to enhance the rigidity of buildings as much as possible on the one hand, and on the other hand, people set up seismic isolation facilities for buildings to improve the earthquake resistance and earthquake resistance of buildings. The traditional seismic isolation method generally sets lead-core rubber seismic isolation bearings in the seismic isolation layer of the building structure, absorbs and dissipates seismic energy through the lead cores in the bearings, prevents the seismic action from being transmitted upwards, and uses softness to overcome rigidity, thereby reducing earthquakes vibration ...
