The improved structure comprises a plate type rubber supporting seat which is clamped and positioned by supporting seat plate and an upper cover plate; SMA wires which are arranged between the supporting seat plate and the upper cover plate, and are arranged in a vertical crossing are wound around the plate type rubber supporting seat; each SMA wire is wrapped around a fixed pulley which is fixed on the supporting seat board or the upper cover plate, and is fixed on the corresponding upper cover plate or the corresponding supporting seat plate (2).
Description
Technical field
The utility model relates to a kind of new-type structure design that subtracts the shock insulation laminated rubber bearing.
Background technology
China has entered the epoch of speedway high speed development.Speedway is directed at the growth at full speed of highway bridge construction to the extension of outlying mountain area.Just increasing in the highway bridge construction at present to the demand that subtracts the shock insulation laminated rubber bearing, require also more and more higher to its shock resistance.The vibration absorption and isolation support that is usually used in bridge and other works at present has: common laminated rubber bearing, pot rubber bearing, spherical bearing etc.Above vibration absorption and isolation support in use all has certain effect.But bad to the compliance that direction of earthquake source changes, absorption and earthquake energy can't discharge fully again, and be therefore serious in the earthquake-prone region fatigue failure.Above problem has become industry technical barrier anxious to be solved.
Summary of the invention
Goal of the invention of the present utility model is to design a kind of shock insulation rubber bearing that subtracts of new structure, make the energy in its absorption shake process as much as possible, and can release energy in time and the geometric deformation of bearing is reduced as much as possible, to be applicable to the earthquake zone, make its seismic energy that can effectively dissipate, increase horizontal rigidity, the displacement of controlling level direction prevents that works from destroying.
Basic imagination of the present utility model is transformed on original laminated rubber bearing basis.Improved laminated rubber bearing is by a seat board and the upper and lower clamping of upper cover plate two block plates location, the SMA silk of arranged crosswise surrounds laminated rubber bearing about being provided with between a seat board and the upper cover plate, and every SMA silk is all walked around a fixed pulley that is fixed on a seat board or the upper cover plate and is fixed on the corresponding upper cover plate or undersetting.
SMA is the english abbreviation of " marmem ".This material is to refuel the ferroalloy of NiTi is arranged, and " China YouSe metal academy " produced the existing history for many years of this alloy material.The physical property of SMA silk and other alloy phase specific energy memory original-shape, as when when 1cm begins to be stretched to 2cm, cancel power after, this SMA alloy silk can be returned to original length size 1cm, and common alloy has permanent set after pulling force is cancelled, and can not be returned to original length; Have super-elasticity, this alloy silk is being subjected under the tension, and its stress-strain diagram does not have constriction, after pulling force is cancelled, curve when its stress-strain diagram leaves former stretching, but the return curve shape almost when stretching curve parallel, get back to initial position again.
The technical solution of the utility model is owing to adopt the SMA silk of upper and lower interlaced arrangement, and when adding seat board generation displacement up and down, the SMA silk produces stretcher strain by pulley.The seismic energy that dissipates in the repeated deformation process of SMA silk under geological process, and increase the rigidity of neoprene bearing, stop displacement structure excessive, make the structure recovery original position, to satisfy the normal instructions for use of structure, new construction has strengthened the automatic recovery ability of neoprene bearing, reaches the damping requirement.When displacement exceeds the neoprene bearing allowed band, the SMA silk can be avoided the neoprene bearing unstability of rolling.Fixed pulley is fixed on upper and lower the seat board by screw thread and two nuts, can adjust the prestressing force level that direction is adjusted the SMA silk that screws of two nuts as required respectively, thereby satisfy different horizontal rigidity of bearing and design displacement request, reach best energy-dissipating and shock-absorbing effect.The SMA silk connects by pulley goes up lower support plate, improved the utilization ratio of SMA silk, the SMA silk is in extended state all the time under the displacement in any direction of this method, the utilization ratio of SMA silk is reached capacity, and satisfy the big displacement request of SMA-neoprene bearing under big shake, avoid the neoprene bearing unstability of rolling because of displacement is excessive.The adaptivity of this bearing is strong, by adjusting the mechanical property that different SMA prestressing force levels can change the SMA neoprene bearing, increases its scope of application.Be applicable to common laminated rubber bearing and teflon slider bearing, and low cost of manufacture, be convenient to installation.
How further specify goal of the invention of the present utility model below in conjunction with accompanying drawing realizes.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is intensive reinforced structural representation.
Wherein 1 is upper cover plate, and 2 are a seat board, and 3 is laminated rubber bearing, and 4 is the SMA silk, and 5 is fixed pulley, and 6 is nut, and 7 is positioning bolt, and 1A/2A is the locating slot of laminated rubber bearing.
The specific embodiment
The laminated rubber bearing 3 that often uses is according to different cross section rectangle and the circular two big classes of being divided into bridge construction in the place of using at present, the cross section of laminated rubber bearing 3 is circle or rectangle, and a pairing upper cover plate 1 and 2 of a seat board are circle or rectangle.For stability of structure respectively is provided with a groove (1A who matches with the physical dimension of pressure-bearing surface up and down of laminated rubber bearing 3 on the bottom surface of end face that props up seat board 2 and upper cover plate 1,2A), laminated rubber bearing 3 is positioned upper bracket plate 2 and upper cover plate) between the end groove (1A, 2A) in.Fixed pulley 5 is positioned on the bolt 7 and by nut 6 and is fixed on a upper cover plate 1 or the seat board 2.Above structure can be finished the installation and the prestressed adjustment of SMA silk very easily.Different displacement according to bearing are wanted, and can adjust the direction that screws of two nuts 6 respectively, thereby adjust the prestressing force level of SMA silk 4, thereby effectively control the horizontal rigidity of bearing, satisfy the different displacement request of bearing, reach best energy-dissipating and shock-absorbing effect.
The connection angle of SMA silk and board-like shock absorption and insulation rubber support determines his anti-deformation intensity, and what Fig. 2 was given is the structural representation of a reinforcement.Can determine according to different horizontal rigidities and design displacement request, be that symmetry or laterally zygomorphic being evenly distributed on a upper cover plate 1 and the seat board 2 that misplace are decided according to designing requirement up and down and fix on bolt 7 on a upper cover plate 1 and the seat board 2.
