Detailed Description
The present invention will be further explained below.
Example (b):
as shown in fig. 1-3, the concrete resilience auxiliary testing device comprises a mounting plate 1, wherein a guide cylinder 2 is fixed on the mounting plate 1, and the central axis of the guide cylinder 2 is coincident with the vertical central axis of the mounting plate 1; a through hole is arranged on the mounting plate 1 at a position corresponding to the inner cavity of the guide cylinder 2; two positioning plates 3 are arranged on two opposite edges of one end of the mounting plate 1, which is far away from the guide cylinder 2, and the two positioning plates 3 are symmetrically arranged; the one end edge that mounting panel 1 was kept away from to two locating plates 3 all parallels with mounting panel 1, and the position of two locating plates 3 and the contact of mounting panel 1 is provided with dop 4, run through on the mounting panel 1 be provided with dop 4 assorted draw-in groove 5.
In this embodiment, the guide cylinder 2 is used for inserting the resiliometer and plays a role in limiting the resiliometer from deviating, so the inner diameter of the guide cylinder 2 should be equal to the outer diameter of the resiliometer, but in order to ensure that the resiliometer can be pushed, the inner wall of the guide cylinder 2 does not generate resistance, so the inner diameter of the guide cylinder 2 is slightly larger than the outer diameter of the resiliometer. When the rebound measurement of the hardened concrete or mortar is carried out, the mounting plate 1 with the two positioning plates 3 is firstly held, and the inner wall surfaces of the two positioning plates 3 or the edges far away from the mounting plate 1 are propped against the surface of the concrete to be measured; no matter whether the surface of the area to be measured is a cylindrical surface or a plane, because the two mounting plates 1 are symmetrically arranged, the edges of one ends, far away from the mounting plates 1, of the two positioning plates 3 are parallel to the mounting plates 1, the guide cylinder 2 is positioned at the center of the mounting plates 1, and the center of the guide cylinder 2 can be kept perpendicular to the surface to be measured; after the resiliometers with matched sizes are inserted into the guide cylinder 2, the axis of the rebound rod of the resiliometer can be always vertical to the concrete detection surface in the test process, the rebound quantity test of a plane or an arc surface of a concrete column can be adapted, and the accuracy is high; simultaneously, two locating plates 3 insert in draw-in groove 5 through dop 4, realize that locating plate 3 and mounting panel 1 can dismantle fixedly, easy dismounting is convenient for accomodate.
Wear-resisting bed course 6 is installed to the internal face of every locating plate 3 and the end of keeping away from mounting panel 1, and wear-resisting property at 3 edges of locating plate can be increased in setting up of wear-resisting bed course 6, frequently with concrete surface contact, can play the effect of protection, ensures the symmetry of locating plate 3, guarantees among the test process that resiliometer tapping rod axis keeps perpendicular with the test surface, further guarantees test data's accuracy. The wear-resisting bed course 6 material in this embodiment is stereoplasm steel, and wear-resisting bed course 6 is fixed in the end of locating plate 3 through countersunk screw 7, after wear-out appears when wear-resisting bed course 6 uses for a long time, can carry out wear-resisting bed course 6's change, easy dismounting through pulling down countersunk screw 7.
