Description
Technical field
The utility model relates to a kind of construction work damping device, particularly a kind of shear support type sinker.
Background technology
Metal sinker is a kind of common type of sinker, utilizes metal flexing to absorb seismic energy, due to the advantage that its stable performance, cost are lower and easy to process, is at home and abroad widely used in recent years.
The metal sinker extensively adopted at present mainly contains tension and compression type, flexure type and shearing-type sinker.Wherein, shearing-type sinker rigidity is large, control sidesway is convenient, but its easy generating plane external drum is bent, causes hysteretic loop to pinch contracting, total cross-section surrender cannot be realized, and edge exist obvious stress concentrate, easily there is crack in advance, largely reducing the fatigue life of sinker, affect sinker and normally work.In addition, the energy-consuming parts of this sinker mainly adopts the mode of welding with fixed part, there is residual stress, and local residual stress may make material yield, thus significantly affects the damping effect of sinker.In order to address this is that, engineering circles proposes three kinds of solutions: 1. weld stiffening rib, the method exists residual stress and distortion; 2. crack, the method can cut off pulling force field, thus weakens rigidity; 3. separately establish device containment surfaces to be out of shape outward, the method complex structure.
Summary of the invention
Goal of the invention: for above-mentioned prior art, proposes a kind of shear support type sinker, and this sinker structure is simple and Hysteresis Behavior is stable.
Technical scheme: a kind of shear support type sinker, comprises upper plate, lower roof plate, some groups of core energy-consuming parts and otic placode; Wherein, described core energy-consuming parts of often organizing comprises two one-tenth core laths arranged in a crossed manner and pin, two ends and the centre position of described every bar core lath are provided with through hole, described pin is through the intermediate throughholes of two core laths, article two, core lath connects otic placode respectively by the pin through its two ends through hole, and described some otic placodes are all fixed on upper plate and lower roof plate.
Further, described each otic placode and core lath contact surface post polyfluortetraethylene plate.
Further, described each otic placode adopts full penetration weld to be connected with between upper plate or lower roof plate.
Further, the through hole of described each otic placode is interior applies graphite powder or lubrication oil.
Further, be provided with the pad through pin between described two the core laths often organized in energy-consuming parts, described gasket surface is provided with antifriction material.
Further, described pin adopts bolt, nut structure, the contact position of the nut of described bolt, bolt and through hole, and the surface that nut contacts with otic placode or core lath all applies antifriction material.
Further, the following Low Yield Point Steel of described core board strip adoption 225MPa or Ductility are the steel of 0.45 ~ 0.5.
Beneficial effect: the sinker that the utility model proposes is primarily of core lath and connecting elements composition.Core lath two ends through hole is connected with the otic placode being connected lower roof plate by pin.Core board bar quantity is even number, is crossed as between two layout, and a pair core lath mid point of intersection is connected by pin.Only there is axial deformation in core lath, utilize the axial deformation dissipation seismic energy of core lath, its theoretical hysteresis loop as shown in Figure 6.The pin of core lath midpoint plays connection two core board bar and reduces calculated length.Sinker operationally, an always core lath pressurized, another core lath tension; Can be there is flexing unstability in the core lath of pressurized, affect sinker energy dissipation capacity, tension core lath does not then have this problem under comparatively huge pressing stress effect.The utility model arranges pin and is connected each other by the lath of two different stresses, tension lath is utilized to provide lateral restraint for pressurized lath, reduce the calculated length of pressurized lath, effectively can prevent lath from occurring flexing unstability, ensure its effective energy dissipation capacity.In addition, core lath logarithm can be increased in engineering as required to control exert oneself and rigidity etc., design also has simplicity and flexibility.
Otic placode pin hole reduces friction by coating graphite powder or wheel lubricating oil, ensures turning power during core lathwork.Article two, core lath contact position posts polyfluortetraethylene plate, arranges the pad of surface with antifriction material between two core laths, thus further reduces friction when core board rotates.The utility model provides and a kind ofly designs and produces good, stressed clear and definite, the stable performance of simple, energy dissipation capacity and the lower shear support type sinker of cost.

Detailed description of the invention
Below in conjunction with accompanying drawing the utility model done and further explain.
A kind of shear support type sinker as shown in Figure 3, comprise upper plate 1, lower roof plate 2, one group of core energy-consuming parts and four otic placodes 4, two otic placodes 4 are connected to upper plate 1 soffit by full penetration weld, two otic placodes 4 by solder design on the upper surface of lower roof plate 2.Wherein, energy-consuming parts comprise adopt below 225MPa Low Yield Point Steel or Ductility be 0.45 ~ 0.5 steel two of preparing become core laths 3 arranged in a crossed manner and a pin 5, two ends and the centre position of every bar core lath 3 are provided with through hole, as shown in Figure 4, the cross-sectional form of core lath has multiple choices, can select according to its stability requirement.Article two, be provided with pad 6 between core lath 3, pad 6 surface is provided with antifriction material polytetrafluoroethylene (PTFE), and pin 5 passes intermediate throughholes and the pad 6 of two core laths 3.Article two, core lath 3 posts polyfluortetraethylene plate with the contact surface Shanghai of pad 6.Article two, the two ends of core lath 3 are connected with otic placode 4 respectively by pin 5, and apply graphite powder or lubrication oil in the through hole of each otic placode, and ensure into two core laths 3 arranged in a crossed manner and be vertically set between lower roof plate.
In this shear support type sinker, pin 5 requires high strength high rigidity, can select ordinary steel or high-strength steel, preferred austenitic manganese steel.Pin 5 adopts bolt, nut structure.At the contact position of the nut of bolt, bolt and through hole, and the surface that nut contacts with otic placode or core lath all applies antifriction material 7, reduces the operating friction between parts with this.Double nut can be adopted fastening when pin adopts during bolt pattern.Upper lower roof plate adopts general steel plate, and function mainly fixes otic placode and the connection with building.
