Description
Technical Field
The utility model belongs to the technical field of the deformation monitoring, concretely relates to be applied to high accuracy deformation monitoring's combination formula and force centering survey mark.
Background
When monitoring deformation of a high slope and a dam, the conventional measuring method adopts conventional measuring marks such as measuring nails and the like, and is assisted by a prism with a centering rod for measurement, and the method can generate large errors due to manual centering; when building horizontal displacement and settlement monitoring, because conventional settlement monitoring sign can't place the prism and carry out horizontal displacement monitoring, traditional measuring method needs to lay horizontal displacement monitoring point separately with the settlement monitoring point, increases work load, and conventional horizontal displacement monitoring adopts the prism of taking the centering rod to measure, because artifical centering can produce great error equally.
Disclosure of Invention
The utility model aims at solving the problem of great error existing in the horizontal displacement and settlement of the existing measurement dam or building.
Therefore, the utility model provides a be applied to combination formula of high accuracy deformation monitoring and force centering survey mark, including the connecting rod, set up in the prism connector of connecting rod top.
And a threaded hole is formed in the upper part of the middle part of the connecting rod.
And a threaded hole is formed above one end of the connecting rod.
The lower extreme of prism connector is provided with the external screw thread.
And a metal ball is arranged at the upper end of the prism connector.
The connecting rod is made of a solid steel bar with the diameter of 12 mm.
The prism connector is made of a solid steel bar with the diameter of 10 mm.
The utility model has the advantages that: the combined forced centering measurement mark applied to high-precision deformation monitoring provided by the utility model does not need to be provided with a measurement nail, can avoid manual centering operation of the prism, and improves the detection precision; when the deformation of a high slope and a dam is monitored, the prism connector and the cross-shaped connecting rod are assembled, the prism can be clamped into the prism connector, and accurate centering can be achieved; when monitoring horizontal displacement and settlement of a building, combining the prism connector and the L-shaped connecting rod as a common measurement mark, and directly erecting a leveling rod on the mark to measure; when the horizontal displacement is measured, the prism is clamped into the prism connector, so that the prism can be accurately centered, and the device has the advantages of simplicity in operation, small error and less workload.
The present invention will be described in further detail with reference to the accompanying drawings.

In the figure: 1. a connecting rod; 2. a prism connector; 3. a metal ball.
Detailed Description
To further illustrate the technical means and effects of the present invention adopted to achieve the predetermined purpose, the following detailed description of the embodiments, structural features and effects of the present invention will be made with reference to the accompanying drawings and examples.
Example 1
For this, the utility model provides a be applied to combination formula of high accuracy deformation monitoring and force centering survey mark as shown in figure 1, figure 2, including connecting rod 1, set up in the prism connector 2 of connecting rod 1 top, prism connector 2 is the forced centering device of prism, and in practical application, only need go into prism connector 2 with the prism card to carry out accurate centering during the measurement.
Further, be provided with the screw hole on the connecting rod 1, the lower extreme of prism connector 2 is provided with the external screw thread, the external screw thread is coincide with the screw hole, and the degree of depth of screw hole is no longer than 10 mm.
Further, the upper end of prism connector 2 is provided with metal ball 3, and metal ball 3 is the solid steel spheroid of diameter 10mm, and metal ball 3 is used for going into prism connector 2 with the prism card to carry out centering operation.
Further, metal ball 3 and prism connector 2 structure as an organic whole, in the time of actual preparation, directly make the upper end of prism connector 2 polish for metal ball 3 can.
Furthermore, the connecting rod 1 is made of a solid steel bar with the diameter of 12mm, and a cross-shaped connecting rod or an L-shaped connecting rod can be formed in practical application.
Further, the prism connector 2 is made of a solid steel rod with the diameter of 10 mm.
Further, the prism connector 2 is manufactured: a steel bar with the length of 100mm and the diameter of 10mm is cut, one end of the steel bar is made into a hemisphere with the diameter of 10mm, the joint of the hemisphere and the steel bar is polished into an arc shape with the diameter of 5mm, and the other end of the steel bar is made into a thread with the length of 10 mm.
Further, a cross-shaped connecting rod is made (as shown in fig. 1, not an actual cross shape): firstly, a steel bar with the length of 100mm and the diameter of 12mm is cut, then, a threaded hole with the depth of 8mm and the diameter of 10mm is punched in the middle of the steel bar along the vertical direction, and the connecting rod 1 can be manufactured.
Further, L shape connecting rod, as shown in fig. 2, at first, a length is 100mm diameter for 12mm rod iron for the intercepting, then reserves 5mm in the one end of rod iron, along vertical to punching the preparation degree of depth be 8mm diameter for 10 mm's screw hole, can make connecting rod 1.
When laying high slope, dam monitoring point, assemble prism connector 2 and cross connecting rod, then, pre-buried at observing pile top, make the top expose the pile top 50mm, only need during the measurement with the prism card go into prism connector 2, can measure after adjusting the prism direction.
When building horizontal displacement and settlement monitoring points are arranged, the prism connector 2 and the L-shaped connecting rod are assembled, then the prism connector is buried in a building monitoring position in a punching fixing mode, the punching fixing depth is 60mm, and the prism connector 2 is adjusted to be vertical to the ground upwards; when monitoring the settlement, the leveling rod can be directly erected on the prism connector 2 for measurement.
When the horizontal displacement is observed, the prism can be measured only by clamping the prism into the prism connector 2 and adjusting the direction of the prism.
