A kind of bean column node low cyclic loading device, this charger has a firm upright counter force wall, laterally one group of counter-force thru-bolt is vertically stretched out in counter force wall, the post test specimen fixing a rectangle is run through in counter-force thru-bolt front portion, laterally vertically run through one group of set bolt in the middle part of post test specimen, set bolt, through horizontal rectangular beam test specimen, fixedly becomes one post test specimen and beam test specimen and adds carrier, in the vertical center of post test specimen, be set with a stake body; Beam test specimen and the post test specimen place of being interconnected are connected and fixed for arc anastomosis, in the end that beam test specimen extends, be set with the lengthening bar of parallel elongate by the set bolt run through, lengthening bar extension end, link together with the form of drawing button with the pressure heads mechanism of servo-pressing machine; This device is applicable to pure specimen joints and loads, thus can reduce sample dimensions, improves test operation convenience; Can avoid occurring Stiffness Deterioration in loading procedure, and be convenient to the distortion of direct measurement node.
Description
Technical field
the utility model relates to a kind of charger of beam column built from concrete, especially a kind of bean column node low cyclic loading device.
Background technology
at present, bean column node low cyclic loading is tested, and classic method generally uses node and component community test specimen to carry out load test, and loads at component ends, and this can bring a lot of drawback, as: sample dimensions is comparatively large, not easy to operate; Cyclic Loading acts directly on beams of concrete or post, can there is Stiffness Deterioration and be unfavorable for Loading Control in beam or post on the one hand, the deformation data recorded on the other hand is the distortion sum of node and component, makes troubles to data processing, easily increases the error of data.In addition, post or beam are generally fixed on the anchoring part such as ground or counter-force wall stand by two crab-bolts by traditional loading method, can only ensure that test specimen does not rotate and perpendicular to the displacement of anchoring part, can not prevent test specimen generation Vertical Anchor seat from moving very well so preferably.
Summary of the invention
larger in order to overcome traditional loading experimental method sample dimensions, not easy to operate, process data inconvenience, error is comparatively large, can produce the problems such as Vertical Anchor seat moves, the utility model provides a kind of bean column node low cyclic loading device, this device is applicable to pure specimen joints and loads, thus can sample dimensions be reduced, improve test operation convenience; Can avoid occurring Stiffness Deterioration in loading procedure, and be convenient to the distortion of direct measurement node.
the utility model solves the technical scheme that its technical matters adopts: a kind of bean column node low cyclic loading device, comprising: counter force wall, counter-force thru-bolt, post test specimen, beam test specimen, servo-pressing machine, lengthening bar, stake body; This charger has a firm upright counter force wall, laterally one group of counter-force thru-bolt is vertically stretched out in counter force wall, the post test specimen fixing a rectangle is run through in counter-force thru-bolt front portion, laterally one group of set bolt is vertically run through in the middle part of post test specimen, set bolt is through horizontal rectangular beam test specimen, and what post test specimen and beam test specimen were fixedly become horizontal stroke " T " font adds carrier, in the vertical center of post test specimen, be set with the stake body that a " # " shape is upright, it can make test specimen more firmly stable; Beam test specimen and the post test specimen place of being interconnected are connected and fixed for arc anastomosis, in the end that beam test specimen extends, the lengthening bar of parallel elongate is set with by the set bolt run through, lengthening bar becomes brachmorphy square tubular shape by Plate Welding, lengthening bar extension end, link together with the form of drawing button with the pressure heads mechanism of servo-pressing machine, this servo-pressing machine can be exerted pressure up and down, to guard column test specimen and beam test specimen with the loading force of above-below direction, thus reach the object that test loads.
during use, stake body is fixed by bolts on earth anchor, reinforces the web member in tight each portion, start servo-pressing machine, give test specimen two-way pressure and load, namely can carry out low-cycle loading experiment.
the beneficial effects of the utility model are: this charger is applicable to pure specimen joints and loads, thus can reduce sample dimensions, improves test operation convenience; Can avoid occurring Stiffness Deterioration in loading procedure, and be convenient to the distortion of direct measurement node.
Accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is further illustrated.
fig. 1 is structure principle chart of the present utility model.
1. counter force walls in figure, 2. counter-force thru-bolt, 3. post test specimen, 4. beam test specimen, 5. servo-pressing machine, 6. lengthening bar, 7. stake body.
Embodiment
in FIG, a kind of bean column node low cyclic loading device, comprising: counter force wall 1, counter-force thru-bolt 2, post test specimen 3, beam test specimen 4, servo-pressing machine 5, lengthening bar 6, stake body 7; This charger has a firm upright counter force wall 1, laterally one group of counter-force thru-bolt 2 is vertically stretched out in counter force wall 1, the post test specimen 3 fixing a rectangle is run through in counter-force thru-bolt 2 front portion, laterally one group of set bolt is vertically run through in the middle part of post test specimen 3, set bolt is through horizontal rectangular beam test specimen 4, what post test specimen 3 and beam test specimen 4 were fixedly become horizontal stroke " T " font adds carrier, in the vertical center of post test specimen 3, be set with the stake body 7 that a " # " shape is upright, it can make test specimen more firmly stable; Beam test specimen 4 with post test specimen 3 place of being interconnected for arc anastomosis is connected and fixed, in the end that beam test specimen 4 extends, the lengthening bar 6 of parallel elongate is set with by the set bolt run through, lengthening bar 6 becomes brachmorphy square tubular shape by Plate Welding, lengthening bar 6 extension end, links together with the form of drawing button with the pressure heads mechanism of servo-pressing machine 5, and this servo-pressing machine 5 can be exerted pressure up and down, to guard column test specimen 3 and beam test specimen 4 with the loading force of above-below direction, thus reach the object that test loads.
during use, stake body 7 is fixed by bolts on earth anchor, reinforces the web member in tight each portion, start servo-pressing machine 5, give test specimen two-way pressure and load, namely can carry out low-cycle loading experiment.
