Description
Technical field:
The utility model relates to the building unit of a kind of vibration proof or vibrations, is specifically related to the Viscoelastic Composite damper, and it is widely used in building damping, earthquake structural engineering field.
Background technology:
Building structure is when design, often do not consider the combination stressed effect of Vierendeel girder and floor, body of wall, cause the beam section bending rigidity excessive, thereby cause building structure post when earthquake take place to destroy or bean column node destroys, and press the generation " strong column and weak beam " of regulation and stipulation, the mode of failure of " member a little less than the node by force ".Traditional method is by the cross section that increases post and increases the anti-seismic performance that the bean column node arrangement of reinforcement improves building structure post and bean column node that this is the antidetonation countermeasure of passive passiveness.There is following problem in the method for existing bean column node seismic design: (1) bean column node arrangement of reinforcement too much causes reinforcing bar intensive, make troubles to building operations, and waste material; (2) cross section of increase post has just increased the rigidity of post, to a certain extent earthquake is had amplification, and this antidetonation to building is unfavorable on the contrary.
Rational and effective antidetonation approach is that structure is installed antishock device (system), bears geological process jointly by antishock device and structure, and promptly common the storage and the dissipation seismic energy is to alleviate and to adjust the earthquake response of structure.This is aggressive antidetonation countermeasure, also is important breakthrough and developing direction in the present antidetonation countermeasure.
The damping member of existing viscoelastic damper is mainly by the be superimposed elastic body that forms and shear steel plate and be superimposed to form of rubber and steel sheet, can be divided into two types according to its stress, a kind of weighing apparatus that supports carries a vibration-insulation damping device (as the notice of authorization number utility model patent for CN2685420Y, CN2685419Y and CN201258541), it is by above-mentioned damping member and be welded on two junction plates of shearing steel plate upper and lower sides face up and down respectively and form, and is located at usually and plays function of shock insulation between construction level; Another kind is can not support weighing apparatus to carry, only passive damper (number is the utility model patent of CN2276584Y as notice of authorization), it by above-mentioned damping member and be welded on respectively shear up and down steel plate up and down two junction plates at two form, usually be located between two building structure, or cooperate diagonal angle that is supported on two-layer beam column up and down or the middle part that is supported on beam column as resiliency supported with rigid support, destroy because of distortion to avoid building structure.This shows, above-mentioned first kind damper obviously is not suitable for the reinforcing of bean column node, though dwindling specification, the above-mentioned second class damper cooperates with rigid support in the armpit up and down that can be installed to bean column node, but following defective is foreseeable, the one, size to dwindle its supporting capacity obviously limited, even do not have the effect of antidetonation, the 2nd, rigid support had both increased cost of production, bring technical difficulty for again production and construction, obviously also be not suitable for the reinforcing of bean column node.In addition, notice of authorization number is in the technical scheme of utility model patent of CN2276584Y, be positioned at the described composite elastic body outside two shearing steel plates and not only bear shear action but also bear effect of contraction, and its another free-ended outside does not have any constraint, obviously can't bear bigger restraint forces.
Summary of the invention:
In view of there is above-mentioned deficiency in prior art, technical problem to be solved in the utility model provides a kind of viscoelastic damper that is applicable to beam-column joint reinforcing.
The technical scheme that the utility model addresses the above problem is as follows:
A kind of beam-column joint reinforcing sector viscoelastic damper, this damper by composite elastic body and first junction plate and second junction plate that are located at composite elastic body two respectively form, wherein, composite elastic body is made up of elastic body that is superimposed and shearing steel plate, shear in the steel plates for every adjacent two in the described composite elastic body, one extends to first junction plate and fixedly connected with it to one, another piece extends to second junction plate and fixedly connected with it to the other end, and have two be positioned at the outside the shearing steel plate with fixedly connected with a plate, it is characterized in that, described composite elastic body is that central angle is 90 ° fan-shaped, each elastic body and shear steel plate and be with composite elastic body concentric fan-shaped; The angle of described first junction plate and the second junction plate lateral surface also is 90 °, and the extended line of the two meets at the center of circle of composite elastic body.
In the technique scheme, not only bear shear action but also bear effect of contraction owing to be positioned at the described composite elastic body outside two shearing steel plates, and its another free-ended outside there is not any constraint, obviously can't bear bigger restraint forces.In order to solve this technical barrier, in the composite elastic body described in the utility model, two another free ends of not fixedlying connected with junction plate of shearing steel plate that are positioned at the outside are provided with two restraining plates, two restraining plates and described two heads of shearing steel plate fuse, and form the restraining structure of the rectangular frame in a cross section.Limited the composite elastic body torsional deformation for fear of restraining plate, be provided with gap X between described restraining plate and the composite elastic body, the size of this gap X equals 1～5mm and is advisable.
Elastic body in the beam-column joint reinforcing sector viscoelastic damper described in the utility model can be that the various viscoelastic materials of using always (as rubber) also can be the composite materials that viscoelastic material and steel sheet layer are superimposed to form.
Beam-column joint reinforcing sector viscoelastic damper described in the utility model, because being central angle, wherein said composite elastic body is 90 ° fan-shaped, be welded on rear damper on first junction plate or second junction plate also for central angle is 90 ° fan-shaped, therefore can be directly installed on armpit under frame structural beam and the post or/and go up the seismic hardening of the interior implementation framework Structure Beam-column node of armpit.In addition, the utlity model has whole damper and do not have little usage space and the advantage such as with low cost of not taking of other attached members, easy for installation, volume.
