Abstract
The utility model belongs to the technical field of building shock insulation and relates to a lead core laminated rubber bearing. The lead core laminated rubber bearing comprises a standard lead core laminated rubber bearing body (1), a steel hinge (2) and hinge connecting pieces (8). An upper connecting plate (3) and a lower connecting plate (4) of the standard lead core laminated rubber bearing body (1) are connected in a pulling mode through the steel hinge (2). Two ends of the steel hinge (2) are respectively fixed on the upper connecting plate (3) and the lower connecting plate (4) through the hinge connecting pieces. A common rubber shock insulation bearing can horizontally deform at earthquake time to bear upper portion structural load and vertical earthquake pressure. The high-strength steel hinge does not provide horizontal rigidity, but can bear vertical earthquake tension produced in the position of the bearing. Thus, not only shock insulation effect of an insulation bearing is achieved, but also the rubber bearing being not damaged when the bearing produces tension is ensured.
Description
Technical field
The utility model belongs to the architectural vibration-insulation technical field, relates to a kind of lead rubber bearing.
Background technology
Base isolation is exactly a kind ofly by between structure and basis Seismic Isolation of Isolation Layer being set superstructure and ground to be separated, thereby reduces the technology of superstructure earthquake effect.Because the Seismic Isolation of Isolation Layer horizontal rigidity is very little, thus shock insulation can extending structure natural vibration period, increase structural damping, prevent upwards transmitting of earthquake ability, and then reduce the geological process of superstructure, reach the purpose of protection superstructure safety.Lead for retractable pencil laminated rubber bearing shock insulation is a kind of seismic isolation technology of maturation, this technology has good isolation property, can automatically reset, and has suitable damping, simple structure has enough durability, thereby has been widely used on the structures such as domestic and international dwelling house, office building, nuclear power station.
The traditional standard lead rubber bearing has good Compressive Performance and shear behavior, can bear the vertical pressure at neoprene bearing place and transverse shearing force and failure not.But when the works depth-width ratio is large, Vertical Earthquake Loads is large or laminated rubber bases horizontal shear distortion when larger, all can produce tensile stress at bearing total cross-section or partial cross section, and the tensile capacity of standard lead rubber bearing is very poor, under less tensile stress, just destruction may be produced, thereby the destruction of whole Seismic Isolation of Isolation Layer may be caused.
The utility model content
The purpose of this utility model is to provide a kind of lead rubber bearing that prevents tensile failure for overcoming the poor defective of prior art Plays lead rubber bearing tensile capacity, this bearing lead for retractable pencil laminated rubber can bear very large earthquake pulling force and failure not, can play again the purpose of shock insulation.
To achieve these goals, the utility model is by the following technical solutions:
In the standard lead rubber bearing, increase the steel hinge, with the steel hinge with lower connecting plate drawknot on the standard lead rubber bearing, the pulling force at standard lead rubber bearing place when bearing geological process by the steel hinge, thus prevent the tensile failure of bearing.
A kind of lead rubber bearing, comprise the standard lead rubber bearing, also include steel hinge and hinge connector, the upper junction plate of described standard lead rubber bearing and lower connecting plate be by steel hinge drawknot, and the two ends of the described steel hinge part that is connected through the hinge is separately fixed on upper junction plate and the lower connecting plate.
Its stage casing of described standard lead rubber bearing be rubber thin-bed and steel sheet successively spacer stack paste the combination rubber layer that forms, be inserted with lead for retractable pencil in the centre of combination rubber layer.
The up and down both ends of the surface of the combination rubber layer of described standard lead rubber bearing are bonded with respectively upper sealing plate and lower shrouding, and described upper sealing plate is connected with lower connecting plate with upper junction plate respectively by set bolt with lower shrouding.
Upper junction plate and the lower connecting plate of described standard lead rubber bearing are equipped with hinge mounting hole.
The described steel hinge part that is connected through the hinge is fixed in the hinge mounting hole, and the steel hinge is that twin shaft is symmetrical arranged.
Described steel hinge is flexible member, and its upper and lower side is connected through the hinge part with upper and lower connector drawknot.
The utlity model has following beneficial effect:
The standard lead rubber bearing can produce horizontal shear distortion and vertical compressive strain, can bear horizontal earthquake shear and superstructure load and vertical seismic force.Both can satisfy the coordination of vertical compressive strain and horizontal distortion because the high strength steel hinge is the flexible member without horizontal rigidity this moment, do not bear again horizontal shear and vertical pressure.And do the time spent when bearing produces tension, and this pulling force will all be born by the high strength steel hinge, and the standard stack neoprene bearing is bearing tension not then.Can reach like this isolating affection of standard stack neoprene bearing, can guarantee that again neoprene bearing does not destroy when bearing produces pulling force, thereby better realize the purpose of highrise building earthquake isolation.This scheme simple structure, easy to make, construction easily both can well realize the earthquake isolation effect of neoprene bearing, can guarantee again the safety of bearing under geological process, can be widely used in Tall Building Foundation shock insulation field.
