Abstract
The utility model provides an arch-shaped soft steel spring piece tension and compression damper, and relates to a building damper. The damper is composed of arch-shaped soft steel spring pieces (1), spring piece fixing clamps (2), rotatable adapting pieces (3), internal bolts (4), external bolts (5) and nuts, wherein the arch-shaped soft steel spring pieces (1) are arranged up and down in pairs, each pair of the arch-shaped soft steel spring pieces (1) forms a closed ellipse, the two ends of the closed ellipses are fixed through the spring piece fixing clamps (2) and clamped and fixed through the bolts and the nuts, and the outer sides of the spring piece fixing clamps (2) are connected with the rotatable adapting pieces (3). According to the arch-shaped soft steel spring piece tension and compression damper, the arch-shaped spring pieces which are staggered up and down are connected together through the fixing clamps and stressed together under the action of axial external force, seismic energy is consumed through elasticity and plastic deformation, the damper has the advantages of being simple in structure, stable in system, quick in response, convenient to machine and adjustable in energy consumption capacity, and components are convenient to replace.
Description
Technical field
Utility model relates to a kind of arc mild steel spring leaf tension and compression damper, particularly relates to a kind of arc mild steel spring leaf tension and compression damper.
Background technology
The mechanism that can produce sliding friction that frcition damper is made up of under certain pretightning force metallic combination member and friction plate, utilizes sliding friction acting dissipation energy.Under the pre-constant load of damper before the surrender of primary structure member, produce slippage or distortion, rely on friction or Damping work seismic energy.Meanwhile, because lengthen natural vibration period after malformation, reduce earthquake input, thereby reached the object that reduces structural seismic response.Such damper has typical coulomb of characteristic, and under course under cyclic loading, energy dissipation capacity is strong, stable work in work, and degradation phenomena is not obvious, and load, frequency and load mode are also less to its performance impact.
Metal damper is that while utilizing earthquake, metal material surrender enters plasticity, produces hysteresis distortion dissipation energy, thereby reaches the object of damping.Be characterized in thering is stable hysteretic characteristic, good anti-low cycle fatigue property and be not subject to impact of environment temperature etc.Metal current damper mainly comprises three classes: mild steel yielding damper, lead extrusion damper and memory alloy damper.
Mild steel has performance after good surrender, and under little shake effect, steel plate is elastic deformation; Under severe earthquake action, steel plate is elastic-plastic deformation, for structure provides certain adhering to rigidity and adhere to damping, can effectively reduce the earthquake response of framework.Mild steel yielding damper take full advantage of after mild steel enters the plastic stage, there is good hysteretic characteristic, good low cycle fatigue property, long-term reliability and be not subject to the features such as environment, temperature affect, be a kind of up-and-coming energy consumer.
Summary of the invention
The object of utility model is to provide a kind of arc mild steel spring leaf tension and compression damper, this damper, by fixed clip, the arc mild steel spring leaf of paired multiple upper and lower interlaced arrangement is linked together, corresponding three level requirementss for fortification against earthquake in seismic design, make damper have simple structure, stable system, are swift in response, are convenient to processing, conveniently install and change parts, energy dissipation capacity adjustable feature.
The object of utility model is achieved through the following technical solutions:
Arc mild steel spring leaf tension and compression damper, described damper is made up of arc mild steel spring leaf, spring leaf fixed clip, the part that is rotatably connected, inner bolt, outer bolt and nut, arc mild steel spring leaf is setting up and down in pairs, every pair forms closed oval, use spring leaf fixed clip at both ends, be fixedly clamped by bolt and nut, and connect in spring leaf fixed clip outside the part that is rotatably connected.
Described arc mild steel spring leaf tension and compression damper, described arc mild steel spring leaf is made the plane that facade is straight line in end, and end is provided with bolt hole.
Described arc mild steel spring leaf tension and compression damper, is provided with bolt hole on described spring leaf fixed clip and the part that is rotatably connected, and the two is bolted.
Advantage and the effect of utility model are:
The utility model links together the arc mild steel spring leaf of paired multiple upper and lower interlaced arrangement by fixed clip, and under axial force effect, multiple spring leafs are jointly stressed.In first power consumption stage, by elastic deformation earthquake energy.In the time that seismic energy is larger, arcuate bombing leaf damper enters second power consumption stage, and spring leaf, under seismic force effects, produces plastic strain gradually, by plastic strain earthquake energy.This power consumption gradient design of power consumption stage by stage, corresponding to a certain extent three level requirementss for fortification against earthquake in seismic design, make the design of damper more reasonable.Meanwhile, can adjust energy dissipation capacity according to actual conditions by the quantity of increase and decrease arcuate bombing leaf, in the time of component damage, also be convenient to replace.The advantages such as the utlity model has simple structure, stable system, is swift in response, and is convenient to processing, conveniently installs and changes parts, and energy dissipation capacity is adjustable.The theory of gradient type power consumption has been proposed simultaneously.

The specific embodiment
Below in conjunction with accompanying drawing illustrated embodiment, utility model is described in further detail.
The utility model is made up of following major part: arc mild steel spring leaf 1, spring leaf fixed clip 2, the part 3 that is rotatably connected, inner bolt 4, outer bolt 5 and nut, bolt hole 6.Arc mild steel spring leaf 1 is arranged in couples up and down, and every pair forms closed ellipse, is fixedly clamped, and connects in spring leaf fixed clip 2 outsides the part 3 that is rotatably connected at both ends with spring leaf fixed clip 2 by bolt and nut.Arc mild steel spring leaf 1 is made up of mild steel.The non-cambered surface in end, but make the plane that facade is straight line, be convenient to fastening.Having two bolts hole 6 in end is that the interspersed bolt of spring leaf fixed clip 2 is used.Arc mild steel spring leaf 1 is appearance in pairs up and down, and concrete magnitude setting is determined by actual conditions.On spring leaf fixed clip 2 and the part 3 that is rotatably connected, be provided with bolt hole, the two is bolted and can moves freely.According to the actual definite number of arc mild steel spring leaf 1 of engineering and the size of each member, manufacture each member according to required size.By spring leaf fixed clip 2, required paired arc mild steel spring leaf is staggered fixing up and down with bolt, then the part 3 that will be rotatably connected is bolted on spring leaf fixed clip 2, is finally connected in building structure.
