Description
Technical field
The utility model relates to civil engineering protection against and mitigation of earthquake disasters field, specifically a kind of steel bar concrete frcition damper.
Background technology
The conventional cushion technique of building is structurally to add energy-consumption shock-absorption device at present, and its shock-dampening method is a kind of of structure Passive Control.Frcition damper is as a kind of energy-dissipating device, and because its energy dissipation capacity is strong, the size of load and frequency thereof is little to its performance impact, and simple structure, draws materials easily, cheap, thereby has good application prospect.Particularly aspect the nearly fault earthquake reaction of control structure and structural seismic response on the middle and senior level, there iing unique advantage.The mechanism that frcition damper carries out vibration isolation to structure is: 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, thereby reach the object that reduces structural seismic response.The at present research of frcition damper technology has obtained certain achievement, but these achievements are mostly expensive, and structure, technique are more complicated, and durability is poor, can not in vast house, promote the use of.Therefore, be badly in need of a kind of power consumption obviously, simple structure, draw materials conveniently, cheap, installation and maintenance facilitates damper.
Utility model content
The purpose of this utility model be to find a kind of can for need antidetonation shock attenuation measure due to limited fund can not take the house of these measures provide a kind of cheap, technique simple, can be promoted the On A Retrofitted Damper of use.And this steel bar concrete frcition damper be exactly a kind of power consumption obviously, simple structure, draw materials conveniently, cheap, installation and maintenance Novel friction damping device easily.
For solving above technical problem, the technical scheme that the utility model adopts is: a kind of new reinforcing steel bar concrete frcition damper, the bottom high tensile reinforcement concrete slab that comprise top high tensile reinforcement concrete slab, is in contact with it, described top high tensile reinforcement concrete slab is fixed by epipleural and superstructure, and described bottom high tensile reinforcement concrete slab is fixed by lower side panel and substructure.
High tensile reinforcement concrete slab bottom, described bottom is provided with a groove, one circular steel pad is arranged in described groove, by an extrusion spring, support, below extrusion spring, be provided with a rectangle steel pad, one adjusting bolt is through described rectangle steel pad, described adjusting bolt bottom is fixedly connected with base by hold-down nut, and top and junction, described rectangle steel pad bottom are provided with an adjusting nut, for regulating the pressure of described extrusion spring.
Further, described top high tensile reinforcement concrete slab and bottom high tensile reinforcement concrete slab contact surface are provided with dabbing layer, and described two dabbing layers outside is respectively arranged with top dabbing layer friction shim and bottom dabbing layer friction shim.
Further, described top high tensile reinforcement concrete slab and bottom high tensile reinforcement concrete slab (5) all adopt strength grade to be greater than the high-strength armored concrete of C50.
As known from the above, the technical scheme tool that the utility model adopts has the following advantages:
1, the utility model steel bar concrete frcition damper has identical damping energy dissipation performance in all directions, can resist the earthquake of any level direction.Damping force can be adjusted by changing upper and lower high tensile reinforcement concrete slab contact surface roughness; Or by pasting at contact surface, pad different damping materials and change.
2, the utility model steel bar concrete frcition damper safety factor is high, and what armored concrete slab was used is high-strength armored concrete more than C50, is characterized in wear-resisting, can bear large pressure, good endurance, and substantially non-maintaining, replacement cost is low.Even under rarely occurred earthquake effect, upper reinforcement concrete slab still can drop on lower rebar concrete slab, can effectively avoid superstructure to collapse.
3, the utility model steel bar concrete frcition damper prices of raw and semifnished materials are cheap, and whole damper is comprised of the good concrete of ageing resistace, steel, pitch ointment material accessory, substantially do not need to safeguard in whole life cycle.These material damping effects are obvious, and durability is very guaranteed, and economy is high, and earthquake only need be taken the circumstances into consideration to carry out later very simple replacing and adjust and just can continue to come into operation, and easy construction, is convenient to large-scale promotion, has great economic and social benefit.
4, the damping force of the utility model steel bar concrete frcition damper not provides by superstructure gravity, but by self spring flexible modulation, spring is protected with anticorrosive paint; good endurance; its damping size can be adjusted at any time by adjusting nut, and simple and convenient is convenient to adapt to various situations.
Accompanying drawing explanation
Fig. 1 is the internal construction schematic diagram of the utility model steel bar concrete frcition damper.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is further described.
As shown in Figure 1, a kind of new reinforcing steel bar concrete frcition damper, the bottom high tensile reinforcement concrete slab 5 that comprise top high tensile reinforcement concrete slab 2, is in contact with it, described top high tensile reinforcement concrete slab 2 is fixed by epipleural 1 and superstructure, and described bottom high tensile reinforcement concrete slab 5 is fixed by lower side panel 12 and substructure; Described top high tensile reinforcement concrete slab 2 is provided with dabbing layer with bottom high tensile reinforcement concrete slab 5 contact surfaces, and described two dabbing layers outside is respectively arranged with top dabbing layer friction shim 3 and bottom dabbing layer friction shim 4.
High tensile reinforcement concrete slab 5 bottoms, described bottom are provided with a groove, one circular steel pad 6 is arranged in described groove, by an extrusion spring 7, support, extrusion spring 7 is provided with a rectangle steel pad 8 below, one adjusting bolt 10 is through described rectangle steel pad 8, described adjusting bolt 10 bottoms are fixedly connected with base 13 by hold-down nut 11, top and described rectangle steel pad 8 junctions, bottom are provided with an adjusting nut 9, by regulating the position of adjusting nut 9 in adjusting bolt 10, can make extrusion spring 7 produce different pressure.
