Description
Technical field
The present invention relates to a kind of aseismic joint damping device.
Background technology
Aseismic joint extensively is present in industry and the civilian construction; Like super-long structural, usually the shrinkage joint need be set; The discrepancy in elevation obviously reaches irregular structure need establish aseismic joint, or has the building structure of differential settlement requirement need establish settlement joint; The building aseismicity regulation and stipulation, when establishing shrinkage joint and settlement joint, its width should meet the requirement of aseismic joint.
Usually after aseismic joint was provided with completion, simple covering treatment measures were only adopted in building operations, and aseismic joint both sides building is not carried out further requirement of shelter; Cause under the geological process; Both sides building easily collision is impaired, and the shake back is difficult for repairing, and the influence building is attractive in appearance, influence structural safety.
Summary of the invention
The present invention provides a kind of aseismic joint damping device, reduces building collision effect under the geological process, the protection damage of building, and construction is simple, cost is low.
In order to solve the problems of the technologies described above; The present invention adopts following technical scheme: a kind of aseismic joint damping device; Comprise the left and right vibration absorption unit that is symmetrically arranged on the concrete structure of aseismic joint both sides, described left and right vibration absorption unit comprises that the inboard is embedded the steel drum in concrete structure, is provided with the piston of band piston rod in the steel drum; The outer end of piston rod is provided with the sphere steel deck-plate, is provided with spring between sphere steel deck-plate and the concrete structure.
The steel drum outer is located concordant with concrete structure and is fixed through the annular steel drum cover plate that is provided with, and sphere steel deck-plate one all outers are corresponding in the horizontal direction with annular steel drum cover plate, between sphere steel deck-plate and annular steel drum cover plate, are provided with spring.
The outer end of piston rod is provided with two-layer sphere steel deck-plate at least.
Steel drum is cylindrical, and is piston-shaped adaptive with steel drum.
Piston comprises the circular steel plate and middle rubber pad of both sides.
Rely on Piston Compression air and spring damping effect to delay collision during earthquake, reduce the collision effect; Annular steel drum cover plate plays the collision of protection structural element and increases the vibration abatement anchorage effect; The sphere steel deck-plate plays buffering, power consumption, protective effect; The sphere steel deck-plate can be done bilayer or multilayer; Spring plays the initial alignment effect; Damping action during pressurized; Return action when not stressing impels the sphere steel deck-plate to drive piston fast reposition.
The present invention is applicable to and is installed in the aseismic joint place, slows down the collision of building under the geological process, the protection damage of building.Play during the earthquake pressurized delay, the power consumption effect, do not reset fast when stressing, can play again when stressed once more delay, the power consumption effect; Can be repeatedly used; Cost is low, and it is convenient to construct; Flexible and convenient to use, can be provided with at correct position as required.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Embodiment: as shown in Figure 1; A kind of aseismic joint damping device comprises the left and right vibration absorption unit that is symmetrically arranged on the aseismic joint 8 both sides concrete structures 7, and described left and right vibration absorption unit comprises that the inboard is embedded the steel drum 1 in concrete structure 7; Be provided with the piston 2 of band piston rod 3 in the steel drum 1; Steel drum 1 is cylindrical, and piston 2 shapes and steel drum 1 are adaptive, and piston 2 comprises the circular steel plate and middle rubber pad of both sides.The outer end of piston rod 3 is provided with two-layer sphere steel deck-plate 6 at least, and in the present embodiment, the sphere steel deck-plate 6 of left vibration absorption unit is double-deck, and the sphere steel deck-plate 6 of right vibration absorption unit is an individual layer.Place, steel drum 1 outer is concordant and fixing through the annular steel drum cover plate 4 that is provided with concrete structure 7, and sphere steel deck-plate 6 one all outers are corresponding in the horizontal direction with annular steel drum cover plate 4, between sphere steel deck-plate 6 and annular steel drum cover plate 4, are provided with spring 5.
The present invention adopts the symmetric arrangement device, is symmetrically arranged on the concrete structure of seam both sides; The position is set for being prone to colliding part, displacement structure is than large part.During practical implementation, can increase as required quantity is set, spacing is arranged to organize device for about 1 meter, also can become rectangular extent to arrange.Annular steel drum cover plate diameter than the big 100mm of cylindrical steel drum diameter about; Sphere steel deck-plate diameter than the big 70mm of cylindrical steel drum diameter about; The steel drum cover plate diameter than the big 30mm of sphere steel deck-plate diameter about.Under geological process,, reduce the collision effect, thereby better protect building through adopting protective device.
During geological process because the both sides body of wall is subjected to displacement, both near, at this moment, contact earlier by the sphere steel deck-plate of protrusion metope, drive the Piston Compression air, compress spring simultaneously, two structures are progressively approaching, and follow the energy-dissipating and shock-absorbing effect.When piston runs to steel drum when bottom soon, the sphere steel deck-plate contacts with annular steel drum cover plate, and the distortion that bumps of sphere steel deck-plate is carried out energy-dissipating and shock-absorbing once more, alleviated the collision effect.This moment, the contact of two structure walls was nearest, but sharp impacts does not directly take place body of wall itself, and the present invention plays the purpose of energy-dissipating and shock-absorbing protection body of wall.When the earthquake distortion recovered, two structure walls separated, and spring and sphere steel deck-plate drive piston fast reposition, wait for geological process once more.
Among the present invention, owing to adopt the sphere steel deck-plate to link to each other with piston, give full play to the two superiority and consume energy and alleviate collision, the piston steel drum structure initial stage plays a major role, and the sphere steel deck-plate later stage plays a major role.The sphere steel deck-plate is convenient to contact power transmission, makes the irregular effect of all directions through the contact of protrusion position, and then drives the piston transfer function; In the piston displacement final stage, the sphere steel deck-plate deforms, and not only brings into play the elastic dissipation energy effect, also alleviates the effect of steel drum structure pressurized, protection piston steel drum structure.Because the mating reaction of spring well is combined as a whole whole system, really play the purpose of protection structure on two sides simultaneously.
