Description
Technical field
The present invention relates to elasticity modulus fields of measurement, and in particular to a kind of concrete test block elastic modulus detection free of demolition
Instrument.
Background technique
Concrete test block elastic modulus tester currently in use is as shown in Figure 1, by lower installation board 1, holding screw
2, upper mounting plate 3, detector mounting base 4, Light deformation detector 5, detector holding screw 6 and detector test platform 7 form.
Its top view is shown in Fig. 2, and centre is concrete test block 8 (being rectangle in figure).Current Basic practice is: the ruler of concrete test block 8
Very little: length × width × height is 150 × 150 × 300；First altimeter is used, according to size shown in Fig. 3, to draw on concrete test block 8
Position line 9 (Fig. 3 only gives the position line in the two adjacent sides of concrete test block and a top surface).By lower installation board 1
It is inserted in 8 outside of concrete test block, is aligned with holding screw 2 on the cross searching for the position line 9 that 8 lower part of concrete test block is finished
Tightly, when make-up, it should ensure that lower installation board 1 is overlapped relative to 8 center of concrete test block.Then with same method, by upper installation
Plate 3 is installed on 9 center of position line finished on 8 top of concrete test block, and detector mounting base 4 is installed on 3 on upper mounting plate, is slightly variable
Shape detector 5 is mounted in detector mounting base 4, being tightened, being made under Light deformation detector 5 by will test instrument holding screw 6
It is directed toward on the detector test platform 7 (a specially cushion block) of lower mounting seat 1 at end.
When test, concrete test block 8 is put into togerther in reaction frame in company with elastic modulus tester, in test, is passed through
Apply certain even distributed force on the above and below of concrete test block 8, at this point, flexible deformation will occur for concrete test block 8, due to
Upper mounting plate 3 and lower installation board 1 are separately fixed on concrete test block 8 by holding screw 2, upper mounting plate 3 and lower installation board 1
Will with the deformation of concrete test block 8 occur micro-displacement, by the Light deformation detector 5 being mounted on upper mounting plate 3 and its refer to
Needle probe (is directed toward the detector test platform 7 on lower installation board 1), detects the opposite micro-displacement of upper and lower mounting plate, mixed to calculate
Solidifying soil 8 elasticity modulus of test block.
Current elastic modulus tester there are the problem of have: 1) all components of elastic modulus tester all be separate
, it to be installed one by one when test every time, waste the plenty of time；2) since upper and lower mounting plate does not fix relative position, installation
Before, it is necessary to it first crosses in test block, anchor point is installed to determine.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of concrete test block elastic modulus testers, can be to avoid every
The dismounting and scribing line problem of secondary test.
The technical scheme to solve the above technical problems is that a kind of concrete test block springform free of demolition measures
Determine instrument, including upper mounting plate, lower installation board and equal-high base, the equal-high base is equipped with multiple, and the upper mounting plate is horizontally arranged at
The top of multiple equal-high bases, the lower installation board are horizontally arranged at the lower part of multiple equal-high bases.
The beneficial effects of the present invention are: in the present invention, since upper mounting seat and lower mounting seat are solid by multiple equal-high bases
It is scheduled on together, it, thus can be to avoid so upper mounting seat and lower mounting seat can be sleeved on the outside of concrete test block simultaneously
The dismounting and scribing line problem tested every time, facilitate taking and placing and preservation.
Based on the above technical solution, the present invention can also be improved as follows.
Further, the equal-high base includes pedestal, seat bar, upper bracket, lower bracket and locator；The seat bar is vertically fixed
On the base, what the upper bracket and lower bracket can move up and down is interspersed on the seat bar, and the upper bracket is located at
The top of the lower bracket；It has been separately equipped in the upper bracket and lower bracket for the upper bracket and lower bracket to be fixed on
The locator on the seat bar；The upper mounting plate and lower installation board are separately mounted in the upper bracket and lower bracket.
Further, the locator is specially bracket holding screw, the bracket clamp screw in the upper bracket and lower bracket
Nail is respectively interposed in the upper bracket and lower bracket, by adjusting the position of the upper bracket and lower bracket and tightens described tight
Screw is determined, with the height of the fixation upper bracket and lower bracket.
Further, the upper and lower part of the seat bar is respectively equipped with contour slot, the bracket in the upper bracket and lower bracket
Holding screw is respectively interposed in the upper bracket and lower bracket, and corresponding can be interspersed in the contour of seat bar upper and lower part
In slot.
Further, fixation hole, the side of the upper mounting plate and lower installation board are respectively equipped on the upper bracket and lower bracket
Through-hole corresponding with the fixation hole in the upper bracket and lower bracket, consolidating in the upper bracket and lower bracket are equipped on frame
Determine that the attachment screw has been respectively interposed between hole and the corresponding upper mounting plate and the through-hole of lower installation board, and the cooperation
Screw is fixed on the upper mounting plate and lower installation board are corresponding in the upper bracket and lower bracket.
Further, the seat bar is equipped with scale.
Further, the position that the upper bracket and lower bracket are connected with corresponding upper mounting plate and lower installation board respectively is
Planar structure.
Further, it is uniformly laid with multiple holding screws respectively on the upper mounting plate and lower installation board, and multiple
The holding screw is inserted through the frame of the corresponding upper mounting plate and lower installation board from side respectively.
It further, further include Light deformation detector, the Light deformation detector is fixed on described by detector mounting base
On upper mounting plate, the lower installation board is equipped with detector test platform, and described in the lower end direction of the Light deformation detector
Detector test platform.
Further, multiple equal-high bases are evenly and symmetrically distributed on the surrounding of the upper mounting plate and lower installation board.
Beneficial effect using above-mentioned further scheme is: in using the present invention, respectively by upper bracket and lower bracket tune
The contour slot of bed rearrangement bar upper and lower part position (under contour slot distance be 75mm, upper contour slot distance be 225mm, meet concrete
The measurement request of test block), whole bracket holding screws are tightened, that is, can determine the distance of detection, not manually in mixed mud test block
Upper scribing line；Since upper mounting seat and lower mounting seat are fixed together by multiple equal-high bases, so upper mounting seat and lower mounting seat
It can be sleeved on the outside of concrete test block simultaneously, then tighten all holding screws on upper and lower mounting plate, unclamp again cooperation
Screw and bracket holding screw, when test, since upper and lower bracket and upper and lower mounting plate unclamp, so will not influence mounting plate
The all of elastic modulus tester to be installed one by one with the displacement of concrete test block, when thus can be to avoid each test
Components save the plenty of time；When jack platen width is not enough put into equal-high base, upper and lower mounting plate and mixed mud test block
After fixing, whole equal-high bases can also be directly removed.
