Description
Technical field
This utility model relates to the survey tool of concrete experiments, particularly relates to line before modulus of elasticity of concrete experiment.
Background technology
When carrying out the experiment of concrete sample elastic modelling quantity, need to paste resistor disc and measure the strain of test specimen, in order to accurately
Measure test specimen deformation, need to be attached to resistor disc the centre of two opposite faces of test specimen, this be accomplished by patch resistor disc it
The artificial setting-out of front employing positions, at present, it is common practice to rule with pencil with ruler, and it exists subject matter and is: (1) is fixed
Position difficulty, setting-out error is relatively big, and phenomenon of doing over again is many；(2) setting-out operation needs repeatedly to overturn concrete sample, on the one hand effect
Low, on the other hand easily cause concrete sample chamfering damaged.
Utility model content
The technical problems to be solved in the utility model is for above-mentioned the deficiencies in the prior art, it is provided that a kind of concrete elastic
Modulus test specimen scale instrument, simple in construction, easy to operate, quick, accurate, improve degree of accuracy and the work efficiency of experiment.
For solving above-mentioned technical problem, technical solution adopted in the utility model is: modulus of elasticity of concrete test specimen mark
Chi instrument, it is characterised in that include that long target and short target, long target meet at right angle with short target plate face, long target and short mark
Being respectively provided with a limit parallel with right-angle side on plate, the distance on described two parallel limits to right-angle side is pasted resistor disc by test specimen
The position line.
The technical scheme optimized further is described long target and short target is rectangle, long target and short target at square
The long edge position of shape intersects vertically.
The technical scheme optimized further is to fix a handle outside described long target and short target respectively.
The length of side that technical scheme is described long target and short target optimized further is according to the length in test specimen patch resistance face
Wide and piezoresistance length determines.
The described long target that the technical scheme optimized further is described is parallel to the patch that the length of side the is test specimen electricity of short target
The length in resistance face, wide 1/2 in the patch resistance face that the length of side is test specimen being perpendicular to short target adds the thickness of short target, and short target is put down
Row is in the width in the patch resistance face that the length of side is test specimen of long target, and it is that test specimen pastes resistance face that short target is perpendicular to the length of side of long target
Long and resistor disc length is subtracted each other the 1/2 of rear length and is added the thickness of long target.
Use and have the beneficial effects that produced by technique scheme: without artificial alignment any two parallel edges, only need
Two targets of scale instrument being adjacent to test specimen, i.e. can determine that the position of Chip-R, convenient location, easy to operate, accuracy is high,
And advantages of simple structure and simple.
Accompanying drawing explanation
Fig. 1 is the structural representation of one embodiment of this utility model.
Fig. 2 is use state 1 schematic diagram of Fig. 1.
Fig. 3 is use state 2 schematic diagram of Fig. 1.
In figure: 1, long target；2, short target；3, handle；4, test specimen patch resistance face.
Detailed description of the invention
Below in conjunction with the accompanying drawing of one embodiment of this utility model, the technical scheme in this utility model embodiment is entered
Row clearly and completely describes, it is clear that described embodiment is only a part of embodiment of this utility model rather than all
Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not making creative work premise
Under any amendment, equivalent and the improvement etc. made within spirit of the present utility model and principle, broadly fall into this practicality new
The scope of type protection.
As it is shown in figure 1, the utility model discloses a kind of modulus of elasticity of concrete test specimen scale instrument, including long target 1, short
Target 2 and handle 3, long target 1 and short target 2 are rectangle, long target 1 and short target 2 while being connected, and long target
1 and short target 2 vertically connect fixing.It is respectively equipped with handle 3 outside long target 1 and short target 2, conveniently takes.Long target 1 and short
The length of side of target 2 determines according to the length and width in test specimen patch resistance face 4 and the length of resistor disc.
As shown in Figures 2 and 3, long target 1 is parallel to the length that the length of side of short target 2 is test specimen patch resistance face 4, is perpendicular to short
The length of side of target 2 is that wide 1/2 in test specimen patch resistance face 4 adds the thickness of short target 2；Short target 2 is parallel to the length of side of long target 1
For the width in test specimen patch resistance face 4, the length that the length of side is test specimen patch resistance face being perpendicular to long target 1 subtracts each other rear length with resistor disc length
1/2 thickness adding long target 1.
When using the position of SMD resistor of this utility model location modulus of elasticity of concrete test specimen, first will need the face of paster
Polishing smooth, be placed in by long target 1 on test specimen patch resistance face 4, short target 2 is positioned at the side that patch resistance face 4 is vertical, long target 1
It is adjacent to two faces of short target 2 with test specimen, draws centrage with pen along long target 1 side, then by long target 1 and short target 2
Dislocation, draws the both sides of resistor disc, i.e. can determine that the patch location of modulus of elasticity of concrete test specimen according to above-mentioned steps.
Use technique scheme, it is not necessary to artificial alignment any two parallel edges, only the two of scale instrument target need to be pasted
Tight test specimen, i.e. can determine that the position of Chip-R, convenient location, avoids concrete sample simultaneously and repeatedly overturns cause broken
Damage, be effectively increased precision and the efficiency of experiment.
