The anti-loosening cross steel pull rod is characterized in that a viscous damper and a spring are additionally arranged on the steel pull rod, the spring is sheathed on the viscous damper, the viscous damper is composed of two steel pipes, the two steel pipes are respectively welded on two steel plates and are penetrated into the spring, the two steel pipes and the spring are sheathed together to form a sleeve, high-viscosity fluid is filled in the sleeve, the two ends of the spring are respectively welded with the two steel plates which fix the steel pipes by the high-viscosity fluid, and the other faces of the two steel plates are welded with the steel pull rod which composes the anti-loosening cross steel pull rod. The spring and the viscous damper are additionally arranged on the steel pull rod, so as to overcome impact on the performance of the steel pull rod by expansion and contraction of wooden components, and keep the steel pull rod always in tension state. Under the function of an earthquake, lateral migration is allowed to be incurred at the major structure, so as to lead the major structure to bear force together with the steel pull rod, thereby improving the capability of the structure to resist lateral migration. The anti-loosening cross steel pull rod is particularly suitable for low-rise frame buildings in areas with strong wind and strong earthquake.
Description
Technical field
The utility model relates to construction engineering technical field, particularly a kind of anti-lax cross reinforcing pull rod with buffering power consumption function.
Background technology
The existing grange of China adopts the wooden construction framework in a large number, because member section is less than normal, a little less than causing lateral deformation stiffness, so, the destructiveness of farm dwelling is serious far beyond the urban architecture of areal in all previous earthquake, caused a large amount of personnel and property loss, so, existing rural area wooden house is carried out the important process that seismic hardening is a construction departments at different levels antidetonation security engineering.
At present, the method that improves farm dwelling wooden construction lateral deformation stiffness mainly is to set up the cross reinforcing pull rod between beam column and between roof truss, and there are some problems in the reliability of this way.At first, timber compoment directly is exposed among the air, along with ambient humidity and variations in temperature can produce contraction or expansion.Timber compoment produces to expand and causes cross reinforcing pull rod two ends nodal distance to dwindle, and the cross reinforcing pull rod is lax, does not have the purpose that strengthens rigidity; Secondly, under seismic loading, the axial tension that the cross reinforcing pull rod bears increases suddenly, when the anti-sidesway ability of agent structure is not brought into play as yet, reinforcing pull rod and timber compoment connected node just destroy, reinforcing pull rod can not be worked in coordination with the opposing seismic load with agent structure, can't reach the purpose with cross reinforcing pull rod raising wooden construction lateral deformation stiffness of expection.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes existing cross reinforcing pull rod, a kind of anti-lax cross reinforcing pull rod with buffering power consumption function is provided, can overcome timber compoment breathing to the reinforcing pull rod Effect on Performance, keep reinforcing pull rod to be in tensioning state all the time, simultaneously, node is not produced too much imposed load again.
The technical solution of the utility model is: comprise frame column, Vierendeel girder, gusset plate, reinforcing pull rod, flower basket bolt etc., it is characterized in that on reinforcing pull rod, setting up viscous damping device and cover spring thereon, the viscous damping device is made up of two steel pipes, two steel pipes are welded on respectively on two block plates, two steel pipes penetrate spring, the formation sleeve is nested together, filling high-viscosity fluid in the sleeve, with the two ends of spring respectively with the fixedly two block plates welding of steel pipe, the other one side of two block plates and form the reinforcing pull rod welding of reinforcing pull rod.
After being installed to above-mentioned member on the wooden construction gusset plate, adjust flower basket bolt, apply pretension, make anti-lax cross reinforcing pull rod with buffering power consumption function.
The utility model is set up spring and viscous damping device on reinforcing pull rod, when reinforcing pull rod is installed, spring is applied pulling force, utilize the return function of spring, overcome timber compoment breathing to the reinforcing pull rod Effect on Performance, keep reinforcing pull rod to be in tensioning state all the time, simultaneously, node is not produced too much imposed load again.Under horizontal dynamic load effect (wind load, seismic load), reinforcing pull rod mainly is to bear pulling force by the stretching of spring, allows the agent structure of this moment to produce certain sidesway, makes agent structure and reinforcing pull rod cooperative bearing, improves the anti-sidesway ability of structure.Carry in the process of stretching and return at reinforcing pull rod, damper produces the power consumption effect.Stop is set on damper, and when the spring amount of tension reached limit value, stop was had an effect, and control structure sidesway amplitude guarantees that agent structure does not produce whole destruction under the big shake effect.
The beneficial effects of the utility model are:
1), under normal mode of occupation, present technique can keep pull bar to be in tensioning state, improves the stability of wooden construction;
2), under seismic loading, pull bar elongation allows wooden construction to produce certain sidesway, has reduced the rigidity of structure, and then has reduced the earthquake response that acts on the wooden construction, can also make pull bar and wooden construction cooperative bearing, improves the shock resistance of wooden construction;
3), the piston of damper is hollow steel pipe, the hollow steel pipe closing panel is provided with spout hole, than the solid piston power consumption better effects if of existing viscous damping device, and economical with materials;
4), during geological process, the buffer capacity of spring has reduced pull bar and has acted on pulling force increasing degree on the node, improves reliability of nodes;
5), technology is simple, compact conformation is easy to change, cost is comparatively cheap;
6), not only can be used for existing wooden construction and reinforce, can also be used for newly-built wooden construction, newly-built steel work, newly-built bamboo structure to improve its lateral deformation stiffness.
