Description
Technical field
The utility model relates to a kind of building unit for limiting angle of rotation of joint displacement and damping, is specifically related to a kind of angle adjustable sector lead viscoelastic corner damper, belongs to Structural Engineering field.
Background technology
Traditional structural seismic is the resistivity relying on structure self, by increasing the cross section of post and increasing the anti-seismic performance that bean column node arrangement of reinforcement improves building structure post and bean column node, so both caused more material consumption, and also made building conduct oneself with dignity and increase, lose more than gain.The existing lead viscoelastic damper that can be used for beam-column joint reinforcing, as a kind of composite damper, is that the shearing lag return distortion producing plastic strain and viscoelastic material after make use of plumbous shearing or extruding surrender is consumed energy.
Energy-dissipating and shock-absorbing technology has huge superiority compared with shock resistance system; do not destroy in paroxysmal exceeding in fortification intensity earthquake, do not collapse; both architecture protection structure itself, the plant and instrument of architecture protection inside configuration and the safety of personnel, economic and practical again.This is aggressive seismic countermeasures, is also the important breakthrough in current seismic countermeasures and developing direction.
Power consumption effect and plumbous shearing just can be played under existing sector lead viscoelastic corner damper member (if Authorization Notice No. is CN101736828B and CN101713226B) takes full advantage of the effect of viscoelastic damper small deformation, extrusion pressing type damper yield displacement is little, the advantage that limit restoring force is large, it is made to do well when being applied to Seismic Response Control and Wind Vibration Response controls, but it is only limitted to use at the bean column node place at 90 ° of angles, architecture structure form diversification in socialist modernization drive, under complicated background, single 90 ° fan-shaped corner dampers can not meet the installation at wide-angle bean column node place or steel structure node place, and the production of multi-angle corner damper has high requirement to production technology, expense also costly.Also the fan-shaped corner damper of angular adjustment can not carried out at home and abroad accordingly.
Utility model content
In view of prior art exists above-mentioned deficiency, the purpose of this utility model is to provide a kind of angle adjustable sector lead viscoelastic corner damper being applicable to multiple angles beam-column joint reinforcing.
Concrete technical scheme is: comprise composite elastic body and be located at the first junction plate and second junction plate at composite elastic body two respectively, wherein composite elastic body is made up of elastic body, shearing steel plate, column lead for retractable pencil and angular adjustment steel plate; Elastic body and shearing steel plate are superimposed, column lead for retractable pencil crosses shearing steel plate and elastic body, shearing steel plate and the angular adjustment steel plate in outside are bolted, middle shearing steel plate extends to the first junction plate to one and is fixedly connected with it, and the angular adjustment steel plate of both sides extends to the second junction plate and is fixedly connected with it to other end; Each elastic body and shearing steel plate and angular adjustment steel plate are the concentric fan-shaped of composite elastic body; The extended line of the first junction plate and the second junction plate lateral surface meets at the center of circle of composite elastic body.
Further, in same arc length, between the adjacent bolt center of circle, central angle is 15 °, and be 30 ° near the center of circle of bolt of the first junction plate and the line in the fan-shaped center of circle and the first junction plate lateral surface extended line, bolt establishes four groups altogether, often organizes at least 2.Can by this damper angular adjustment to 105 °, 120 °, 135 ° three different angles by bolt.Also can in same arc length between the adjacent bolt center of circle central angle be set to 5 ° or other angles, make damper angle adjustable to other angles, be applied to different building structure.
In composite elastic body, both sides shearing steel plate not only bears shear action but also bear effect of contraction together with the angular adjustment steel plate of both sides with one end that angular adjustment steel plate connects, and the outside of its another free end is without any constraint.Therefore, at outside shearing steel plate, two restraining plates are set near one end of the first junction plate, two restraining plates are connected with the head of described outboard shear steel plate, form the restraining structure that a cross section is rectangular, and this restraining structure is not connected with both sides angular adjustment steel plate.
Be provided with gap between restraining plate and composite elastic body, this gap length is set to 1 ~ 5mm and is advisable, with the torsional deformation avoiding restraining plate to limit composite elastic body.
Described column lead for retractable pencil is at least two, and this is because the distortion of the beam and column in building structure when earthquake or wind carry is very complicated, and therefore whole damper must bear and make composite elastic body produce torsional deformation perpendicular to the torsion of column lead for retractable pencil.Also column lead for retractable pencil can be sheared well and dissipation energy when described torsional deformation in order to make shearing steel plate, the diameter of described column lead for retractable pencil and the size of the visual damping force of quantity and the sectional dimension of damper are determined, when needs damping force is large and damper dimensional requirement is less, the quantity of column lead for retractable pencil can be increased, or increase the diameter of column lead for retractable pencil, vice versa.
Elastic body in angle adjustable sector lead viscoelastic corner damper can be conventional various viscoelastic materials (as rubber) also can be the composite material that viscoelastic material and steel sheet layer are superimposed to form.
Angle adjustable sector lead viscoelastic corner damper described in the utility model, its adjusting angle can be 90 °, 105 °, 120 °, 135 ° four different angles, therefore can be directly installed on there is multiple wide-angle bean column node Structure in Complex Structure, steel work Liang Yuzhu under armpit or possess the structure node place of respective angles, to realize the increase of building structure at bean column node place limiting angular displacement and the seismic hardening of node.The utility model angle of regulation range is wide, makes simple, is applicable to self assembly, the angular adjustment in manufacturer production and use procedure.In addition, the utility model has that whole damper structure is simple, angular adjustment is convenient, volume is little does not take usage space and the advantage such as with low cost.
