Preferably, the diameter of the long threaded rod is not less than 10mm, and length is not less than 80mm；Long threaded rod it is pre-buried away from
From 1/3rd for whole long screw thread pole length.
Preferably, the material of the long threaded rod is rustless steel or the ferrum that one layer of anti-corrosive antirusting paint is coated with outside it
Matter.
Preferably, the flat board is that thickness is not less than 10mmPVC plastic plates not less than 2mm steel plates or thickness；It is described
The surface configuration of flat board is circle, rectangle, square or triangle.
Preferably, the central cross-section diameter of the metal hemisphere is not less than 20mm, and metal hemisphere center is provided with
Screwed hole II is adapted with long threaded rod, both are fixed together by the cooperation of screw thread.
Preferably, the material of the built-in fitting is PVC plastic material, with certain rigidity and intensity, it is ensured that
There is no destruction and moderate finite deformation when concrete structure member is poured.
This utility model beneficial effect：
（1）Certainty of measurement is greatly improved.This utility model directly can be fixedly connected with the prism of full-automatic total powerstation so that
Measurement error is greatly reduced, certainty of measurement is greatly improved.
（2）Reduce monitoring cost.The monitoring point being laid on concrete structure member is more easily damaged in the construction stage, repaiies
Multiple cost is big and causes measurement error to become big.This utility model is carried out when work is not measured using stainless steel protection lid
Protection, other operations will not be damaged when constructing to measuring point；The composable dismounting of monitoring device that this utility model is provided and can
Reuse so that monitoring cost greatly reduces.
（3）Monitoring cycle is long, does not affect the construction of xoncrete structure and uses.Because measuring point is built-in type, not only can
It is monitored in the construction stage, be even completed after coming into operation normally to be monitored to concrete structure member.
