Description

A kind of concrete test block elastic modulus tester free of demolition
Technical field
The utility model relates to elasticity modulus fields of measurement, and in particular to a kind of concrete test block elasticity modulus free of demolition Analyzer.
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.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of concrete test block elastic modulus testers, can keep away Exempt from the dismounting tested every time and scribing line problem.
The technical solution that the utility model solves above-mentioned technical problem is as follows: a kind of concrete test block springform free of demolition Analyzer, including upper mounting plate, lower installation board and equal-high base are measured, the equal-high base is equipped with multiple, the upper mounting plate level peace Mounted in the top of multiple equal-high bases, the lower installation board is horizontally arranged at the lower part of multiple equal-high bases.
The beneficial effects of the utility model are: in the present invention, due to upper mounting seat and lower mounting seat pass through it is multiple Equal-high base is fixed together, so upper mounting seat and lower mounting seat can be sleeved on the outside of concrete test block simultaneously, thus Taking and placing and preservation can be facilitated to avoid the dismounting and scribing line problem tested every time.
Based on the above technical solution, the utility model can also do following improvement.
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: when the utility model is used, respectively by upper bracket and subiculum The contour slot of seat adjusting seat bar upper and lower part position (under contour slot distance be 75mm, upper contour slot distance is 225mm, is met mixed The measurement request of solidifying soil test block), whole bracket holding screws are tightened, that is, can determine the distance of detection, not manually in mixed mud It crosses in test block;Since upper mounting seat and lower mounting seat are fixed together by multiple equal-high bases, so upper mounting seat and lower peace Dress seat can be sleeved on the outside of concrete test block simultaneously, then tighten all holding screws on upper and lower mounting plate, unclamp again Attachment screw and bracket holding screw, when test, since upper and lower bracket and upper and lower mounting plate unclamp, so will not influence peace Loading board thus will can install one by one elastic modulus tester with the displacement of concrete test block to avoid when testing every time All 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 After test block fixes, whole equal-high bases can also be directly removed.
