Description
Technical field
The utility model is related to a kind of fixtures, more particularly, to a kind of fixture of test Hysteresis Behavior.
Background technology
In recent years, being increasingly enhanced with the economic strength in China, building trade is maked rapid progress therewith to flourish.It is all kinds of
Building is gradually built up in Divine Land.Such as Grand National Theatre, 2008 Beijing Olympic Games stadiums, Shanghai World's Fair venue
117 mansion of space structure and Tianjin, Guangzhou television tower, the systems complexity such as Shanghai World Financial Center high-rise building work
Journey.The life security of this kind of large public building relationship numerous people, it is ensured that the security performance of structure is particularly important.
The Hysteresis Behavior of node undoubtedly plays very important effect in civil structure field, in space structure
The quality of interior joint Hysteresis Behavior has apparent influence, measuring node to exist anti-seismic performance, the wind-excited responese etc. of total
Stress performance under Cyclic Loading has vital meaning to the deformability and energy dissipation capacity of evaluation node.
Utility model content
The purpose of this utility model is exactly to overcome the problems of the above-mentioned prior art and providing one kind can meet
The fixture of the test Hysteresis Behavior of the requirement of test specimen Hysteresis Behavior test.
The purpose of this utility model can be achieved through the following technical solutions：
A kind of fixture of test Hysteresis Behavior, including upper fixture, lower fixture, and what is be arranged between two fixtures is in axis
Symmetrically arranged two pieces of backing plates, the upper fixture are fixedly connected on the upper end of two pieces of backing plates, and the lower surface of upper fixture is equipped with pressure
Tight plate, the pressure plate are connect through elastic element with upper fixture,
The lower fixture is movably connected in the lower end of two pieces of backing plates, can be slided up and down along backing plate.
When being put into tested component between the upper fixture and lower fixture, the elastic element is in by compression shape
State.As preferred embodiment, elastic element is spring.So when being detected, when no matter testing pulling force or pressure,
It can ensure that upper fixture tightly clamps tested component with lower fixture, increase the rigidity of clamping, by the load for the machine that loads
Power is evenly transferred on tested component.
Sliding slot is offered on the backing plate, the both ends of the lower fixture are movably connected in sliding slot and can be along sliding slot
It moves up and down, to realize the adjustment of loading force.
It is additionally provided with elastomeric pad on the inside of the backing plate, which is more than the side of tested component, in this way may be used
To control the position for being tested component from another direction, and using the elasticity of elastomeric pad itself, than contacting effect firmly
More preferably, to make loading force steadily be transmitted on tested component.
The elastomeric pad is through being bolted on backing plate.
The bolt stretches into that the length in elastomeric pad is adjustable, and control bullet can be further adjusted by the adjustment of length
Property gasket and backing plate and tested component between clamping force, realize loading force preferably transmit.
Compared with prior art, the utility model passes through the mutual cooperation between each component so that no matter pressure or draws
The loading force that power is applied can be fine and be evenly transferred on tested component so that test specimen can either bear pulling force and also can
Pressure is enough born, the requirement of test specimen Hysteresis Behavior test can be met.

Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram at pressure plate.
In figure, fixture under 1- upper fixtures, 2- pressure plates, 3- elastic elements, 4- backing plates, 5- elastomeric pads, 6- bolts, 7-.
Specific implementation mode
The utility model is described in detail with reference to specific embodiment.Following embodiment will be helpful to this field
Technical staff further understands the utility model, but does not limit the utility model in any form.It should be pointed out that ability
For the those of ordinary skill in domain, without departing from the concept of the premise utility, various modifications and improvements can be made.
These belong to the scope of protection of the utility model.
Embodiment
A kind of fixture of test Hysteresis Behavior, structure includes as shown in Figure 1 upper fixture 1, lower fixture 7, is connected to
On the pedestal for testing the upper and lower side of load machine, pressure is applied to the component being placed in fixture and pulling force carries out Hysteresis Behavior survey
Examination.It is equipped with two pieces of backing plates 4 being axisymmetricly arranged between two fixtures, upper fixture 1 is fixedly connected on the upper of two pieces of backing plates 4
End, and it is equipped with pressure plate 2 in the lower surface of upper fixture 1, which connect through elastic element 3 with upper fixture 1, such as Fig. 2 institutes
Show.Lower fixture 7 is movably connected in the lower end of two pieces of backing plates 4, and sliding slot is offered on backing plate 4, and the both ends of lower fixture 7 are movably connected in
It can move up and down in sliding slot and along sliding slot, to realize the adjustment of loading force.
When being put into tested component between upper fixture 1 and lower fixture 7, elastic element 3 is in confined state.The present embodiment
The middle elastic element used is spring, and spring is demountable, in the different components of test or to pulling force and pressure
Power is replaced when having different require.So when being detected, when no matter testing pulling force or pressure, can ensure on press from both sides
Tool with lower fixture tightly clamp tested component, increase the rigidity of clamping, by the loading force for the machine that loads be evenly transferred to by
On test suite.
The inside of backing plate 4 is additionally provided with elastomeric pad 5, which is more than the side of tested component, in this way can be from
The position for being tested component is controlled on another direction, and using the elasticity of itself of elastomeric pad 5, than contacting effect firmly more
It is good, to make loading force steadily be transmitted on tested component.
As more preferred embodiment, elastomeric pad 5 can also be connected to by bolt 6 on backing plate 4, and bolt
6 length that stretch into elastomeric pad 5 are adjustable, by the adjustment of length can further adjust control elastomeric pad and backing plate and
Clamping force between tested component realizes that loading force preferably transmits, preferably meets wanting for test specimen Hysteresis Behavior test
It asks.
Specific embodiment of the utility model is described above.It is to be appreciated that the utility model not office
It is limited to above-mentioned particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims,
This has no effect on the substantive content of the utility model.
