Abstract
The utility model provides a building vertical member loading device with adjustable, includes base, adjusting screw, test piece earth anchor, vertical long bolt, crossbeam, punching jack and supporting sensor, servo actuator, the base is divided into base and lower base two parts, reserve the bolt hole in the middle of the last base of base, adjusting screw's the one end and the lower base fixed connection of base, adjusting screw's the other end is stretched into the last base preformed hole of base, the last base preformed hole of base with the adjusting screw phase -match, last base and the vertical long bolt of base pass through free bearing swing joint, the other end of vertical long bolt pass the crossbeam preformed hole with punching jack and supporting sensor nut connect, the utility model overcomes the biggest shortcoming of traditional vertical loading method has very strong practicality in low all repetition tests.
Description
Technical field
The utility model relates to building test field, is specifically related to the reversed loading building vertical member.
Background technology
In recent years the Experimental Study on Seismic Behavior of component is come into one's own gradually, actual conditions for imitation specimen better in process of the test can apply vertical load to component, and to there is in process of the test vertical load change greatly in existing vertical loading device, surface of contact angle easily causes many drawbacks such as slippage, can not simulating actual conditions and meet testing requirements well.
Current researcher's majority is pseudo-static experimental test specimen being adopted to low Zhou Fanfu.When carrying out Low-cycle Test, horizontal push-and-pull load can be applied by horizontal servo actuator, and many troubles can be run into when applying vertical load, the method of now commonplace applying vertical load is expanded by column cap, applies vertical load after pillar hoisted in position between capital and portal frame crossbeam by steel plate, roller bearing, lifting jack, sensor.Because testing column applies vertical axis power to design load under vertical state, in the process of horizontal servo actuator push-and-pull, the vertical height of pillar can change, because the lifting jack applying vertical load can not adjust accordingly with the change of vertical height, payload values is remained unchanged, easily cause slippage because surface of contact is more, so the larger change of vertical load can be caused in whole process of the test simultaneously.
For addressing this problem, if imagination vertical loading device can do concentric circles with the push-and-pull of component rotate the change just effectively can avoiding vertical load like this.
Utility model content
For the weak point of above charger, proposing one can adjustable vertical loading device.
This device is a kind of adjustable building vertical member charger, and comprise base, adjusting screw(rod), test specimen earth anchor, vertical long bolt, crossbeam, punching lifting jack and supporting sensor, described base is divided into upper bed-plate and lower bottom base two parts; Prepared screw-bolt hole in the middle of the upper bed-plate of described base; One end of described adjusting screw(rod) is fixedly connected with the lower bottom base of base; The other end of described adjusting screw(rod) puts in the upper bed-plate preformed hole of described base, and the upper bed-plate preformed hole of described base and described adjusting screw(rod) match; The upper bed-plate of described base is flexibly connected by free bearing with vertical long bolt; The other end of described vertical long bolt is connected with described punching lifting jack and supporting sensor nut through crossbeam preformed hole.
The distance of described adjusting screw(rod) and adjustable frames Up/down base.
Because the change moment everywhere with vertical long bolt vertical height is different in the process of push-and-pull, the curvature of component is different throughout, thus component be not around with base present circular-rotation with the tie point on ground.By regulating the distance between Up/down base, make the upper section of rotating hinge on upper bed-plate and test component base in same level position, to realize concentric rotation.
Horizontal push-and-pull load can be applied by horizontal servo actuator, and is realized by the punching lifting jack between vertical long bolt and crossbeam and supporting sensor at applying vertical load, and sensor connects display to show the axle power applied.Be loaded on axial pressure by servo actuator during loading, axial pressure passes to test specimen by crossbeam.Vertical counter-force reaches ground, laboratory by vertical long bolt and base and reserves groove.
Advantage of the present invention to realize the rotation of charger with test component, and look different the up-down adjustment run-on points of test component substructure height, reduces the change of vertical load in test loading procedure to greatest extent.
