Description
Technical field
The present invention relates to civil engineering protection against and mitigation of earthquake disasters field, specifically a kind of steel bar concrete frcition damper.
Background technology
The cushion technique that current building is conventional structurally adds energy-consumption shock-absorption device, and its shock-dampening method is the one of Structure uniformity.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, draw materials easily, cheap, thus there is good application prospect.Particularly in the reaction of control structure near-fault ground motion and structural seismic response on the middle and senior level, there is unique advantage.Frcition damper to the mechanism that structure carries out vibration isolation is: produce slippage or distortion under the pre-constant load of damper before primary structural member surrender, rely on friction or Damping work seismic energy, thus reach the object reducing structural seismic response.The research of current frcition damper technology has achieved certain achievement, but these achievements are mostly expensive, and structure, technique are more complicated, and durability is poor, can not promote the use of in vast house.Therefore, be badly in need of a kind of power consumption obviously, simple structure, draw materials conveniently, cheap, installation and maintenance facilitates damper.
Summary of the invention
The object of the invention is to find a kind of can for need antidetonation shock attenuation measure and 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 solution adopted in the present invention is: a kind of new reinforcing steel bar concrete frcition damper, the bottom high strength RC plate comprise top high strength RC plate, being in contact with it, described top high strength RC plate is fixed by epipleural and superstructure, and described bottom high strength RC plate is fixed by lower side panel and substructure;
A groove is provided with bottom the high strength RC plate of described bottom, one circular steel pad is arranged in described groove, supported by an extrusion spring, a rectangle steel pad is provided with below extrusion spring, one adjusting bolt is through described rectangle steel pad, be fixedly connected with base by hold-down nut bottom described adjusting bolt, top and described rectangle steel pad bottom junctions are provided with an adjusting nut, for regulating the pressure of described extrusion spring.
Further, described top high strength RC plate and bottom high strength RC plate contact surface are provided with dabbing layer, are respectively arranged with top dabbing layer friction shim and bottom dabbing layer friction shim outside described two dabbing layers.
Further, described top high strength RC plate and bottom high strength RC plate (5) all adopt strength grade to be greater than the high-strength armored concrete of C50.
As known from the above, the technical solution adopted in the present invention tool has the following advantages:
1, new reinforcing steel bar concrete frcition damper of the present invention has identical damping energy dissipation performance in all directions, can resist the earthquake in any level direction.Damping force adjusts by changing upper and lower high strength RC plate contact surface roughness; Or by pasting at contact surface, pad different damping materials to change.
2, new reinforcing steel bar concrete frcition damper safety factor of the present invention is high, and armored concrete slab uses the high-strength armored concrete of more than C50, is characterized in wear-resisting, can bear large pressure, good endurance, and substantially non-maintaining, replacement cost is low.Even if 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 new reinforcing steel bar concrete frcition damper prices of raw and semifnished materials of the present invention are cheap, and whole damper is made up 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, only need take the circumstances into consideration to carry out very simple replacing and adjust just can continuing to come into operation after earthquake, and easy construction, is convenient to large-scale promotion, has great economic and social benefit.
4, the damping force of new reinforcing steel bar concrete frcition damper of the present invention not provides by superstructure gravity, but by self spring flexible modulation, spring anticorrosive paint is protected; good endurance; its damping size can be adjusted at any time by adjusting nut, simple and convenient, is convenient to adapt to various situation.
Accompanying drawing explanation
Fig. 1 is the internal construction schematic diagram of new reinforcing steel bar concrete frcition damper of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present invention is further described.
As shown in Figure 1, a kind of new reinforcing steel bar concrete frcition damper, the bottom high strength RC plate 5 comprise top high strength RC plate 2, being in contact with it, described top high strength RC plate 2 is fixed by epipleural 1 and superstructure, and described bottom high strength RC plate 5 is fixed by lower side panel 12 and substructure; Described top high strength RC plate 2 and bottom high strength RC plate 5 contact surface are provided with dabbing layer, are respectively arranged with top dabbing layer friction shim 3 and bottom dabbing layer friction shim 4 outside described two dabbing layers.
A groove is provided with bottom described bottom high strength RC plate 5, one circular steel pad 6 is arranged in described groove, supported by an extrusion spring 7, extrusion spring 7 is provided with a rectangle steel pad 8 below, one adjusting bolt 10 is through described rectangle steel pad 8, be fixedly connected with base 13 by hold-down nut 11 bottom described adjusting bolt 10, top and described rectangle steel pad 8 bottom junctions are provided with an adjusting nut 9, by regulating the position of adjusting nut 9 in adjusting bolt 10, extrusion spring 7 can be made to produce different pressure.
Under geological process, the relative displacement of level is produced between the top high strength RC plate 2 of new reinforcing steel bar concrete frcition damper of the present invention and bottom high strength RC plate 5, the pressure of extrusion spring 7 makes to produce damping energy dissipation between the high strength RC plate contact surface of top and the bottom, thus reaches and weaken the object of geological process on the impact of superstructure
Above-mentioned each function is only for illustration of the present invention, and wherein the specific implementation of each function can carry out equivalents and improvement on the basis of technical solution of the present invention, all should not get rid of outside protection scope of the present invention.
