It is widely present, as the compression bar both ends in Cable dome are all connected with the rope in several directions, supporting role of these ropes to compression bar
Equivalent to elastic bearing.For this problem of the elastic bearing of uniaxial force component, the required hinged-support of binding project
And hold-down support, devise multipurpose bearing.It has small, simple structure, low cost, may be used as uniaxial force component
Different-stiffness elastic support, hinged-support and hold-down support.
Utility model content
The purpose of this utility model is to provide a kind of multipurpose bearing for axis compression member experimental study, the branch
Seat has the function of hinged-support, the elastic support of different-stiffness and hold-down support concurrently.
The technical solution for realizing the utility model aim is:A kind of multipurpose branch for axis compression member experimental study
Seat, including upper end bearing, lower end bearing, place test specimen, upper end bearing and lower end bearing are equal between upper end bearing and lower end bearing
Including inner face, the first plate of groove, the second plate, 2 dismountable springs, several dismountable fixed cylinders, removable is set
The knife hinge unloaded;Wherein the bearing includes three kinds of connection modes:
A, knife hinge is assemblied between the first plate and the second plate and knife hinge coordinates with groove, forms hinged-support;
B, spring, knife hinge are assemblied between the first plate and the second plate and knife hinge coordinates with groove and spring is located at knife hinge two
Side, forms elastic support;
C, fixed cylinder both ends are individually fixed in the first plate, the second plate, form hold-down support.
The utility model uses for reference the knife of uniaxial force component compared with bearing, and multipurpose bearing has hinged-support, different-stiffness concurrently
The function of elastic support and hold-down support, small, simple structure, parts are few, low cost, turning power are good, solve axis
The elastic bearing problem of heart primary structure member.Spring can be replaced as needed, to obtain the elastic bearing of required rigidity.
The utility model is described further with reference to Figure of description.

Embodiment
With reference to Fig. 1 to Fig. 6, a kind of multipurpose bearing for axis compression member experimental study, including upper end bearing, under
Bearing is held, test specimen is placed between upper end bearing and lower end bearing, upper end bearing and lower end bearing include inner face and set groove 7
The first plate 1, the dismountable fixed cylinder 14 of 5,2, the dismountable spring of the second plate 2,2, dismountable knife hinge 6;Wherein should
Bearing includes three kinds of connection modes:
A, knife hinge 6 is assemblied between the first plate 1 and the second plate 2 and knife hinge coordinates with groove 7,
B, spring 5, knife hinge 6 are assemblied between the first plate 1 and the second plate 2 and knife hinge coordinates with groove 7 and spring 5 is located at
Knife cuts with scissors 6 both sides,
C, 14 both ends of fixed cylinder are individually fixed in the first plate 1, the second plate 2.
The function of hinged-support is wherein realized using A kind connection modes, the elasticity of different-stiffness is realized using B kind connection modes
The function of bearing, the function of hold-down support is realized using C kind connection modes.
2 upper surface of the second plate of upper end bearing is threaded cylinder 11 and universal testing machine upper end phase in the utility model
Even, 2 lower face of the second plate of lower end bearing sets rectangular strip 12, which is inserted into the lower channel of universal testing machine
In.
In two kinds of connection modes of A and B, knife hinge 6 is identical, but the knife hinge 6 in B connection modes is arranged on cylinder 8, cylinder
