Description
Technical field
The dynamic test field of concrete is the utility model is related to, especially a kind of concrete, which is split, draws experiment to split drawing device.
Background technology
In terms of concrete material dynamic characteristic scientific research, the drawing characteristic of splitting for studying concrete is the one of concrete research field
The important content of item, and relatively other axle last items are drawn and the experiment of shearing, split and draw experiment to presently, there are the problem of bigger,
Its problem mainly have some（1）It is all that in the vertical direction is carried out that what now many laboratories were carried out, which splits drawing experiment, with
This direction for splitting drawing carries out experiment and the problem of very big be present because vertical direction concrete up and down two split and socket contacting surface
All it is to be contacted in an arc-shaped device, support concrete is the straight line that two faces are in contact.Due in the vertical direction, so meeting
It is easy to allow concrete run-off the straight, the meeting that tilting can not only allow the failure of an experiment serious, which destroys, splits drawing device, it could even be possible to allowing
Split drawing device to drop from concrete top, there is security risk.（2）The either original of the structure of human factor or concrete itself
Cause, split load load when pair in be always one be difficult solves the problems, such as, centering do not directly result in strictly experiment load when send out
Raw inclination makes the failure of an experiment.So in experiment now in spite of when spent big time on in, it is last or unavoidable real
Test failure.（3）Now split the problem of drawing device does not only exist centering, and the heavy trouble of the device tested, installation is very not
Just.In order to solve problem above well, the mode of loading is improved to be changed by original vertical direction loading by the utility model
For the loading of horizontal direction.And propose the loading of a set of horizontal direction splits drawing device.
The content of the invention
Technical problem to be solved in the utility model be to provide a kind of concrete split draw experiment split drawing device, can realize
Horizontal addload, ensure that centering is accurate.
In order to solve the above technical problems, technical scheme is used by the utility model：
A kind of concrete, which is split, draws experiment to split drawing device, including two split drawing backing plate, each split and draw backing plate to include bottom plate, bottom plate
Upper center is longitudinally provided with semicolumn, and the front/rear end of semicolumn end face outside, top end face and bottom plate is equipped with screwed hole, two halves
The top of cylinder, the front and rear bolt connection of bottom plate have upper limit plate and lower limiting board.
The two halves cylinder end face outside bolt connection disk.Disk ensure loading post and vertical semicolumn it is uniform by
Power, the centering of test specimen is also convenient for, left and right loading post is loaded on the same line.
The lower limiting board is higher by bottom plate upper surface 2mm-3mm.So, front and rear lower limiting board can block test specimen,
Thus concrete both sides can have been played with a fixation, also allowed for centering, the installation of concrete.
Rectangular channel is equipped with the upper limit plate and lower limiting board, bolt passes through rectangular channel and semicolumn or upper limit plate
Or lower limiting board is detachably connected.
Test specimen is fixed by the bolt on rectangular channel when installing test specimen, to avoid movement；After preloading just
Bolt can be suitably unclamped, can so ensure that screw rod thereon can be with two when splitting displacement of the drawing generation to concrete center position
Splitting for side draws backing plate to move together.
A kind of concrete of the utility model, which is split, draws experiment to split drawing device, has following technique effect：
1）, by using horizontal addload mode, solve and drawing device unstable easily run-off the straight split during vertical loading
Problem, improve the security of experiment.
2）, the apparatus structure it is simple, easily installation, it is easy to operate, greatly save the time of experiment.
3）, by setting bottom plate of the middle part with semicolumn, bottom plate is front and rear to set lower limiting board, so solves test specimen centering
The problem of inaccurate, the success rate of experiment and the accuracy of the data of experiment is set also to greatly improve.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples：
Fig. 1 is structural representation of the present utility model.
Fig. 2 is schematic diagram when the utility model is tested.
In figure：Split and draw backing plate 1, bottom plate 2, semicolumn 3, upper limit plate 4, disk 5, lower limiting board 6, load post 7, concrete
Test specimen 8.
Embodiment
As shown in Figure 1-2, a kind of concrete, which is split, draws experiment to split drawing device, is made of steel plate, ensures enough intensity.
The device is split including two and draws backing plate 1, each splits and draws backing plate 1 to include bottom plate 2, and the upper center of bottom plate 2 is longitudinally provided with semicolumn
3.The front/rear end of the end face outside of semicolumn 3, top end face and bottom plate 2 is equipped with screwed hole, the top of two halves cylinder 3, bottom plate 2
Front and rear bolt connection has upper limit plate 4 and lower limiting board 6.So pass through the setting in structure, it is ensured that concrete sample clamping
Centering can be completed after fixation, improves accuracy.
Operation principle and process：
1）, first take one to split to draw backing plate 1, by one end of front and rear lower limiting board 6 and split drawing backing plate and be connected and tighten bolt, it is complete
Lain in after on experimental bench.
2）, one side of cube Shanghai and Nanjing figure test specimen is placed on above-mentioned 1）In split draw backing plate 1 on make the one side of concrete tight
Split and draw 1 semicircle cambered surface of backing plate, and be generally centered.
3）, the another side of concrete somewhat lifted, another is split and draws the bottom plate 2 of backing plate 1 to be put into concrete base,
The position of appropriate adjustment concrete, makes it between two front and rear lower limiting boards 6.
4）, put well after, respectively fix before and after the both ends of lower limiting board 6 bolt, make concrete be stuck in front and rear lower limiting board 6 it
Between fixation do not offset.
5）, fixed top upper limit plate 4, concrete is placed under loading post 7, preloaded.
6）, remove when, loose nut, unload upper limit plate 4, lower limiting board 6 etc..
