Description

A kind of one-way eccentric hinged-support and using method thereof
Technical field
The present invention relates to construction engineering technical field, specifically a kind of one-way eccentric hinged-support and using method thereof.
Background technology
In the scientific research of building engineering field, the stress performance of the normal method research member that adopts test. For Elimination test machineMember two ends are retrained to the impact causing, test component often adopts hinged-support. But existing edge of a knife bearing and ball hinged support, onlyCan be used for the axial compression test of member, cannot carry out eccentric compression and the tension test of member.
Existing edge of a knife bearing uses comparatively extensive, but under elevated pressures effect, knife-edge part produces higher stress and concentrates, easilyTeeth groove plate is caused to wearing and tearing; And in the time that member arrives critical condition, the slip of member easily causes collapsing suddenly of bearing, rightTest a machine and threaten with the safety of testing crew. The disclosed a kind of name of China Patent No. CN201320536286.6 is called " twoTo cambered surface hinged-support device " and the disclosed a kind of name of China Patent No. CN201220114934.4 be called " a kind of test loads bearing "Etc. technical scheme, all belong to the improvement to existing edge of a knife bearing. The former has made the triangular knife notch portion of existing edge of a knife bearing intoCircular arc, but still exist deadweight larger, cannot carry out the shortcoming such as eccentric compression and tension test of member. The latter is at existing cutterOn the basis of mouth bearing, add the parts such as jagged teeth groove, can be applicable to axial compression and eccentric compression experimental study simultaneously, but alsoFundamentally do not solve the ubiquitous problem of edge of a knife class bearing.
The disclosed a kind of name of China Patent No. CN201420860322.9 is called " the universal support saddle device of pressurized tests ". Comprise threeIndividual module, each module comprises difform entity steel ingot and plate, although can realize hinged rotation, its complex structure,And cannot be used for tension test; Meanwhile, the large portion of bearing is made up of entity steel ingot, conducts oneself with dignity larger, needs in actual applications customization,Be not suitable for middle-size and small-size test.
The disclosed a kind of name of China Patent No. CN201420831904.4 is called " a kind of novel static(al) loading experiment cylinder hinge rotationBearing ". Bearing bottom adopts flat board and semicolumn parts to support, and ensures that bearing can freely rotate; Bearing top is provided withThe folder support being made up of screw rod and baffle plate etc., in order to fixation test component ends. Although this bearing can be used for axial compression and inclined to one sideHeart pressurized tests, but cannot carry out tension test; And this seat structure is comparatively complicated, be not easy to install and use.
The disclosed a kind of name of China Patent No. CN201210568608.5 is called " a kind of space for the test of asymmestry section bias voltageLoad bearing ". On the level of common testing machine and the basis of vertical actuator, add the special portion such as conversion equipment and ball pivotPart, in order to the actual loading situation of better simulation bending component. But this seat structure is comparatively complicated, be not easy to install and use,Can not carry out tension test.
Above-mentioned patent has represented the prior art that this area is more advanced, but still has problems, therefore, and design oneKind is simple in structure, easy for installation, is convenient to deposit, and can carries out axial compression, axial tension, eccentric compression and eccentric tension etc.The hinged-support of type test is solution that those skilled in the art need badly.
