Embodiment
As shown in Figure 1, the utility model comprises for stretching into the fixed bar 1 in the hole that is arranged on point position, and for being connected and fixed the joint of bar 1 and convergence instrument 6, one end of fixed bar 1 is fixedly connected with the inwall in described hole, the other end of fixed bar 1 is provided with external thread 5, described joint is made up of with the hook ring 3 for being connected convergence instrument 6 thread bush 4, hook ring 3 is fixedly connected with thread bush 4, on thread bush 4, have the threaded hole 2 for being connected and fixed bar 1, the screw thread in threaded hole 2 matches with external thread 5.
In the present embodiment, one end of described fixed bar 1 is bonding by the inwall in resin anchoring agent and described hole.Described hook ring 3 welds with thread bush 4.
When concrete enforcement, described fixed bar 1, thread bush 4 and hook ring 3 are all adopted and are made of a steel; The length of described fixed bar 1 should guarantee that fixed bar 1 is inner fixing definitely firm in described hole, difficult drop-off.
The utility model is applicable to the fields such as mine engineering, Geotechnical Engineering, Tunnel Engineering, coordinates convergence instrument to can be used to accurately measure the relative amount of convergence between two surfaces.
In conjunction with Fig. 2, when the utility model uses, first, point position predetermined on engineering surrounding rock 8 is holed, and matches with length and the diameter of fixed bar 1 respectively in hole depth and aperture; Then, one end of fixed bar 1 is fixedly secured in described hole by resin anchoring agent, guarantee that the external thread 5 of the other end setting of fixed bar 1 exposes measured surface; Two convergence instrument point equipments 7 of general minimum installation, cooperatively interact and restrain measurement as one group of measuring point, and two convergence instrument point equipments 7 are arranged on respectively on two surfaces to be measured; Then, described joint screw thread is connected on fixed bar 1, and two hooks at convergence instrument 6 two ends are hooked respectively on the hook ring 3 of two convergence instrument point equipments 7, rotation regulates described joint, guarantees that the tape measure of convergence instrument 6 is not distorted; Finally, operation either converges instrument 6 can complete once convergence measurement on request, and after once convergence has measured, the lower described joint of dismounting is restrained measurement next time.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification of above embodiment being done according to the utility model technical spirit, change and equivalent structure change, and all still belong in the protection domain of technical solutions of the utility model.
