Be held in the load end plate connection of test specimen two ends and realize, wherein the load end plate of test specimen two ends is connected by pull rod, actuator with plus
It carries end plate and is in same horizontal line.
Due to the self gravity of load end plate and pull rod, load end plate can generate the trend of tenesmus, ordinary circumstance, test
When can using tensile ties and load end plate on weld hanging plate by the way of come prevent load end plate tenesmus, further with guarantees work
Levelness when dynamic device load.According to the actual situation, it loads on end plate and welds hanging plate, load end plate is hung over into this side on test specimen
Formula effect is most ideal.Which will load end plate by hanging plate and hang on test test specimen, can effectively prevent load end plate tenesmus,
Simultaneously not only convenient for the connection of load end plate and pull rod, but also it is easily guaranteed that load end plate and actuator are maintained at same level height.
However, due to civil engineering structure tests sample dimensions multiplicity, test objective difference etc., for the band of certain test processing
The load end plate of hanging plate is tended not to for other tests, namely new test generally is required to redefine the suspension of hanging plate every time
Position is further welded again.It is lower that this also results in load end plate recycling rate of waterused, not only waste of resource but also time-consuming.According to
Practical investigation still lacks a kind of load end plate that can be used for low cycling loads test with preferable general applicability at present.
Summary of the invention
The purpose of this utility model is to provide it is a kind of can satisfy different size specimen test requirements be suitable for low week
The load end plate with adjustment height hanging plate of Cyclic Loading Test.
In order to solve the above technical problems, the technical solution of the utility model is as follows:
Suitable for the load end plate with adjustment height hanging plate of Low-cycle Test, including hanging plate and for it is corresponding
The connecting plate of pull rod connection, hanging plate include side plate and be set at the top of side plate or bottom for hanging the extension being connected on corresponding test specimen
Edge, side plate are posted by the connecting plate, and the guiding elongated slot vertically extended, guiding length are provided on connecting plate or side plate
It is equipped with the connection bolt for realizing that side plate is connected with the connecting plate in slot, connects and has screwed locking nut on bolt.
The guiding elongated slot is opened on the connecting plate.
It hangs along the bottom for being set to side plate, side plate constitutes L-shaped structure with edge is hung together.
It offers respectively for installing bolt at four angles of connecting plate and realizes the first bolt penetration hole being connected with pull rod.
The connecting plate is square the steel plate of structure.
There are two the guiding elongated slots, and two guiding elongated slots are arranged symmetrically along the vertical centerline of connecting plate.
Load end plate further includes the Double hole pad passed through for two connection bolts.
The second bolt penetration hole corresponding with each guiding elongated slot respectively is provided on side plate, connection bolt is threaded onto corresponding
It is oriented in elongated slot and bolt penetration hole.
The utility model has the following beneficial effects: when the utility model is used, connecting plate is connected with pull rod, the extension edge of hanging plate
It then hangs to be connected on test specimen and guarantees that the height and position of connecting plate does not drop, adjusted by movement of the connection bolt in guiding elongated slot
Hanging plate after height adjusts, screws locking nut, realizes and hang with respect to the high and low position of connecting plate to adapt to various sizes of test specimen
Plate is fixedly connected with connecting plate, can be tested.
