Description
Technical field
The present invention relates to a kind of building construction vibration control device, particularly relate to a kind of lattice lead extrusion damper of building construction vibration control.
Background technology
Metallic damper (metallic yielding damper) is the various forms of damping energy dissipation devices made from mild steel or other softer metals.Has good Hysteresis Behavior behind the metal yield, the elastoplasticity hysteresis distortion power consumption that utilizes some metal to have.Metallic damper comprises 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 that the portion of energy of the structural vibration surrender hysteretic energy by metal is dissipated, thereby reaches the purpose that reduces structural response.
Lead damper is to take full advantage of lead to have the characteristics such as density is large, fusing point is low, plasticity is high, intensity is low, corrosion resistant is strong, lubricating ability is strong, simultaneously owing to have higher ductility and flexibility, so in deformation process, can absorb a large amount of energy, and has a stronger distortion follow-up control, and by dynamic recovery and recrystallization process, its tissue and performance also can return to the state before the distortion, thus lead damper have application life unrestricted, the damping that provides reliable, to not needing the advantage such as maintenance in displacement sensitive, simple structure, the work.But it has the shortcomings such as restorative difference and lead contamination.
All metal damper has that recoverable deformation is large, damping capacity is strong and durability, corrosion resistance, the advantage such as anti-fatigue performance is good, operating temperature range is large and maintenance cost is low.
At present the lead extrusion damper of research and development has China Patent No. 201120031801.6 to disclose a kind of name to be called " torsional lead extruding damper " utility model patent etc., and it is relatively poor that these dampers can't be used for power consumption or the effect of building structure.
Summary of the invention
The purpose of this invention is to provide a kind of lattice lead extrusion damper, effectively improve plumbous utilization rate and energy efficiency.General lead extrusion damper is because the restriction of plumbous extrusion mouth causes lead to be subjected to the scope of effectively extruding power consumption less, and most of lead can't be brought into play effective effect, so energy consumption effect also has been subject to impact.Therefore the present invention passes through to increase plumbous extrusion mouth, and corresponding each plumbous extrusion mouth has corresponding corresponding region to consume energy separately, and then improves the energy efficiency of damper.Can increase the integral rigidity of building structure when under normal condition, using, and when running into earthquake, utilize the surrender power consumption of lattice lead extrusion damper can reduce the earthquake response of building structure, building structure is played a very good protection.
Technical scheme is as follows:
The lattice lead extrusion damper mainly is comprised of urceolus, end plate stiffener, end plate, movable axis, fixed axis, connecting lug, plumbous extrusion mouth, lead, sealing ring, movable axis conduit, spacing supporting, postive stop baffle, lattice frame, vertical lattice plate and horizontal lattice plate etc., at the urceolus two ends end plate stiffener and end plate are set all, two ends all arrange sealing ring and spacing supporting in the cylinder of urceolus, a side arranges movable axis therein, is connected with end plate and opposite side arranges fixed axis; Movable axis and fixed axis all arrange connecting lug, it is characterized in that: between movable axis and the urceolus lattice frame is set, the middle part of movable axis arranges a plurality of plumbous extrusion mouths, and plumbous extrusion mouth is corresponding one by one with the zone that is horizontally divided into of lattice frame, and the outside of plumbous extrusion mouth arranges respectively postive stop baffle.Lattice frame is made of vertical lattice plate and horizontal lattice plate.
Advantage of the present invention and beneficial effect:
Effect of the present invention and advantage are that stock utilization is high, energy consumption effect is good; The simultaneously fabrication and installation of lattice lead extrusion damper are simple, easy to use, both can be used for the seismic design of new building engineering, can also be used for the reinforcing maintenance of existing engineering.
