Detector mounting base 4 is installed on 3 on upper mounting plate, and Light deformation detector 5 is mounted in detector mounting base 4, by tightening spiral shell
Bolt 6 tightens, and the lower end of Light deformation detector is made to be directed toward on the cushion block 7 of lower mounting seat 1.
During experiment, concrete test block is put into togerther in boosting frame in company with elastic modulus tester, in test, by
Apply certain even distributed force on the top and bottom of concrete test block, at this point, flexible deformation will occur for concrete test block, due to upper installation
Plate 3 and lower installation board 1 are separately fixed at by holding screw 2 on stone, and upper mounting plate 3 and lower installation board 1 will be with the changes of test block
Micro-displacement occurs for shape, is popped one's head in by the Light deformation detector 5 being mounted on upper mounting plate 3 and its pointer and (is directed toward lower installation board 1
On cushion block 7), the opposite micro-displacement of lower installation board in detection, to calculate concrete test block elasticity modulus.
Current elastic modulus tester there are the problem of have：1) all parts of elastic modulus tester are all to separate
, it to be installed one by one during experiment every time, waste the plenty of time；2) since upper lower installation board does not fix relative position, before installation,
It must first cross in test block, to determine installation anchor point.

And upper end, the holding screw is respectively arranged on lower installation board and upper mounting plate and the outer wall of tightening concrete test block, the inspection
Survey instrument mounting base be installed on upper mounting plate, the Light deformation detector is installed in detector mounting base, further include blade, under
Side wall, upstream target end and the upper peace of vernier, vernier holding screw and upper vernier, the downstream target end and lower installation board
The side wall of loading board is respectively equipped with the plug and jack for the grafting that matches, and the blade sequentially passes through the lower vernier of insertion and upper vernier,
The lower vernier and upstream are put on and are designed with vernier holding screw respectively, and described vernier holding screw one end passes through lower vernier and upper
Vernier one end side wall of vernier and blade is blocked in cooperation.
Preferably, at least two groups of the lower vernier and upper vernier, and it is distributed in the lower installation board and upper mounting plate pair
Answer the surrounding of position.
Preferably, the plug prevents lower installation board and upper mounting plate from being rotated rotating around lower vernier and upper vernier for rectangle.
What the present invention generated has the beneficial effect that：The present invention has arbitrarily adjustment detection range, and positioning accuracy is high, pacifies installation and dismantling
Unload the advantages that facilitating.
