Description
Technical field
The utility model relates to the experiment field of civil engineering work, particularly a kind of for concrete column bias-load test unit.
Background technology
The bias-load test of concrete column is one of civil engineering work fundamental test.Numerous scholars are also by the eccentric compression mechanical property of bias-load experimental study post.But in the process of test, there are a lot of difficulties:
1, the size of test specimen itself is larger, not easy to operate;
2, meet the constraint condition at test specimen two ends more difficult;
3, the charger at two ends is difficult to alignment;
4, before prestrain, be difficult to guarantee that test specimen is vertical.
To sum up problem causes test efficiency low, and the precision of test findings is inadequate.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of concrete column bias-load test unit, can locate easily and the load testing machine that aligns, and improves work efficiency and the test accuracy of test.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of concrete column bias-load test unit, comprise sun hinge plate and cloudy hinge plate, sun hinge plate is provided with raised line, on cloudy hinge plate, relevant position is provided with groove, in the position of the both sides of sun hinge plate or cloudy hinge plate, is provided with chute, and that in chute, slides is provided with back up pad, on chute lateral wall, be provided with through hole, shearing bolt is connected with the threaded hole in back up pad through through hole.
The outer end of described shearing bolt is provided with handle.
The position of cutting with scissors plate near sun in back up pad is provided with handle.
Described back up pad is parallel with raised line.
In back up pad, be also provided with the bolt hole for fixed support plate.
A kind of concrete column bias-load test unit that the utility model provides, by the back up pad and the chute that arrange, thereby be convenient to the loading of test unit, be convenient to set accurate eccentric throw and fixed position, the shearing bolt arranging is convenient to back up pad to be locked in chute, now between raised line and groove, do not stress, be further convenient to load testing machine.The utility model carrys out lock support plate by shearing bolt, easy to operate simple, is easy to realize centering and the stability problem of load testing machine, can improve test efficiency, improves test precision.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is plan structure schematic diagram of the present utility model.
Fig. 2 is the A-A cross-sectional schematic of Fig. 1.
Fig. 3 is side-looking structural representation of the present utility model.
Fig. 4 is the B-B cross-sectional schematic of Fig. 1.
Fig. 5 is that the utility model carries out the bias-load structural representation in when test.
In figure: sun hinge plate 1, cloudy hinge plate 2, back up pad 3, handle 4, handle 5, shearing bolt 6, bolt hole 7, concrete column 8, raised line 9, groove 10, chute 11, eccentric throw H.
Embodiment
In Fig. 5, at concrete column 8 two ends, device of the present utility model is set, due to the existence of eccentric throw H, and the raised line 9 in sun hinge plate 1 and cloudy hinge plate 2 and the structure of groove 10, it is difficult being carried in reliably concrete column 8 two ends.
In Fig. 1～5, a kind of concrete column bias-load test unit, comprise sun hinge plate 1 and cloudy hinge plate 2, sun hinge plate 1 is provided with raised line 9, on cloudy hinge plate 2, relevant position is provided with groove 10, in the position of the both sides of sun hinge plate 1 or cloudy hinge plate 2, is provided with chute 11, chute 11 interior slips be provided with back up pad 3, on chute 11 lateral walls, be provided with through hole, shearing bolt 6 is connected with the tapped through hole in back up pad 3 through through hole.Structure thus, when loading, make shearing bolt 6 through the threaded hole in back up pad 3, thereby the position of lock support plate 3, so that when loading, by back up pad 3 supporting sun hinge plates 1 or cloudy hinge plate 2, and raised line 9 is not contacted with groove 10, make when loading sun hinge plate 1 or cloudy hinge plate 2 can not produce skew.
Preferred as in Fig. 2, the outer end of described shearing bolt 6 is provided with handle 5.Structure, is convenient to turn shearing bolt 6 thus.
Preferred as in Fig. 1～3, the position of cutting with scissors plate 1 near sun in back up pad 3 is provided with handle 4.Structure, is convenient to mention sun hinge plate 1 thus.It should be noted that, when the moon hinge plate 2 is positioned at top, the position of handle 4 is exactly the position near cloudy hinge plate 2.
Preferred as in Fig. 1, described back up pad 3 is parallel with raised line 9.Structure, can not interfere the support between raised line 9 and groove 10 thus.
Preferred as in Fig. 2～4, in back up pad 3, be also provided with the bolt hole 7 for fixed support plate 3.Structure after test completes, is screwed into bolt in bolt hole 7 thus, back up pad 3 can be fixed in chute 11, in order to avoid back up pad 3 is lost.
Or contrary, when sun hinge plate 1 is positioned at top, sun is cut with scissors to plate 1 and be bearing on the upper surface of cloudy hinge plate 2, in order to avoid damage raised line 9 or groove 10.
During test, as in Fig. 2, the threaded hole promoting in back up pad 3 by handle 4 before test aligns with the through hole on chute 11 lateral walls, is screwed into shearing bolt 6 by the locking position of back up pad 3, and now the supported plate 3 of cloudy hinge plate 2 supports, and can not rock, and is convenient to load.During test, at two loading ends of test specimen, respectively place a set of device of the present utility model, according to the eccentric throw H of testing requirements, determine position of the present utility model.After preliminary work completes, start prestrain and finely tune load testing machine, after prestrain completes, suspending loading equipemtn.Unscrew shearing bolt 6, back up pad 3 falls in the chute 11 of sun hinge plate 1.Continue test until complete.After off-test, by shearing bolt 6, be connected with bolt hole 7, back up pad 3 is fixed in sun hinge plate 1.This bias-load test unit can improve test efficiency, improves test precision.
