The damper is high in material utilization ratio, good in energy consumption effect and excellent in reset function, meanwhile, the damper is simple in manufacturing and mounting and convenient to use, not only can be used for the aseismic design of a newly-built constructional project, but also can be used in the reinforcement and maintenance of an existing project.
Description
Technical field
The invention belongs to building structure technology field, particularly relate to a kind of reversion Self-resetting lead extrusion damper that intersects.
Background technology
Metallic damper (metallic yielding damper) is the various forms of damping energy dissipation devices made by mild steel or other softer metals.Mainly comprise mild steel damper, lead damper and marmem (shape memory alloys is called for short SMA) damper etc.The mechanism that it carries out vibration isolation to structure is dissipated by the surrender hysteretic energy of the portion of energy of structural vibration by metal, thus reach the object reducing structural response.
Wherein lead damper, make full use of the features such as lead density is large, fusing point is low, plasticity is high, intensity is low, corrosion resistant is strong, lubricating ability is strong, owing to having higher ductility and flexibility, so a large amount of energy can be absorbed in deformation process, and there is stronger deformation tracking ability, and by dynamic recovery and recrystalline process, its structure and properties also can return to the state before distortion, and therefore lead damper has that application life is unrestricted, the damping that provides reliable, do not need the advantages such as maintenance in displacement sensitive, simple structure, work.But general lead extrusion damper is due to the restriction of plumbous extrusion mouth, and the plumbous scope by effectively extruding power consumption is less, and most of lead cannot play effective effect, and therefore energy consumption effect receives impact, also has the shortcomings such as restorative difference and lead contamination.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the invention provides a kind of reversion Self-resetting lead extrusion damper that intersects, it effectively improves plumbous utilization rate and energy efficiency.By arranging threaded hole, plumbous extruding rotating disc, movable axial lead can be made effectively to be extruded, flow and recrystallization, and adjoining spiral hole, plumbous extruding rotating disc reversely rotate, and therefore make lead all can participate in shear extrusion, significantly improve the energy-dissipating property of damper.The integral rigidity of building structure can be increased when using in normal state, and when running into earthquake, utilize the surrender power consumption of intersection reversion Self-resetting lead extrusion damper can reduce the earthquake response of building structure, building structure is played a very good protection.
The technical solution used in the present invention is as follows:
The present invention's one intersection reversion Self-resetting lead extrusion damper, comprise urceolus, end plate stiffener, end plate, movable axis, fixed axis, connecting lug, lead, sealing ring, movable axis conduit, spacing supporting and postive stop baffle, all arrange end plate stiffener and end plate at urceolus two ends, in the cylinder of urceolus, two ends all arrange sealing ring and spacing supporting; Side arranges movable axis wherein, and opposite side arranges fixed axis with end plate is connected; Movable axis and fixed axis all arrange connecting lug; The middle part of described movable axis arranges multiple lead extruding rotating disc, and each lead extruding rotating disc has multiple threaded hole, and the direction, angle of inclination in adjoining spiral hole is contrary; Between each lead extruding rotating disc and movable axis, all back-moving spring is set; Adjacent threaded hole and plumbous extruding rotating disc are contrary with direction of rotation in the process that lead is sheared mutually.
Beneficial effect of the present invention:
The present invention by arranging multiple lead extruding rotating disc by back-moving spring on movable axis, it has the threaded hole by lead, when being subject to tension and compression effect, lead is subject to the squeezing action of plumbous extruding rotating disc and extrudes the threaded hole on rotating disc by lead, but plumbous extruding rotating disc rotates, because the direction, angle of inclination in adjoining spiral hole is contrary, therefore the direction of rotation of adjacent lead extruding rotating disc is contrary, and then makes plumbous direction of rotation present awave rotation.After reaching maximum displacement, plumbous extruding rotating disc can have the trend returning to equilbrium position under action of reset spring, and then forms antipodal motion process.The motion ratio of such lead, range of movement, movement degree are all significantly improved, and energy dissipation capacity improves.
Stock utilization of the present invention is high, energy consumption effect good, and has good reset function etc.; The fabrication and installation of the Self-resetting of intersection reversion simultaneously lead extrusion damper are simple, easy to use, both may be used for the seismic design of new building engineering, and can also be used for the strengthen maintenance of existing engineering.

Detailed description of the invention
Describe the present invention below in conjunction with drawings and Examples:
Embodiment: as shown in Figure 1 and Figure 2, the present invention includes urceolus 1, end plate stiffener 2, end plate 3, movable axis 4, fixed axis 5, connecting lug 6, lead 9, sealing ring 10, movable axis conduit 11, spacing supporting 12 and postive stop baffle 13, all arrange end plate stiffener 2 and end plate 3 at urceolus 1 two ends, in the cylinder of urceolus 1, two ends all arrange sealing ring 10 and spacing supporting 12; Side arranges movable axis 4 wherein, and opposite side arranges fixed axis 5 with end plate 3 is connected; Movable axis 4 and fixed axis 5 all arrange connecting lug 6; The middle part of described movable axis 4 arranges multiple lead extruding rotating disc 8, and each lead extruding rotating disc 8 has multiple threaded hole 7, and the direction, angle of inclination in adjoining spiral hole 7 is contrary; Between each lead extruding rotating disc 8 and movable axis 4, back-moving spring 14 is all set; Adjacent threaded hole 7 and plumbous extruding rotating disc 8 are contrary with direction of rotation in the process that plumbous 9 shear mutually.
Operating principle of the present invention: when being subject to tension and compression effect, lead is subject to the squeezing action of plumbous extruding rotating disc and extrudes the threaded hole on rotating disc by lead, but plumbous extruding rotating disc rotates, because the direction, angle of inclination in adjoining spiral hole is contrary, therefore the direction of rotation of adjacent lead extruding rotating disc is contrary, and then makes plumbous direction of rotation present awave rotation.After reaching maximum displacement, plumbous extruding rotating disc can have the trend returning to equilbrium position under action of reset spring, and then forms antipodal motion process.The motion ratio of such lead, range of movement, movement degree are all significantly improved, and energy dissipation capacity improves.
