Abstract
The utility model discloses a hidden settlement observation point mark piece which comprises a sleeve and measuring bolts installed in the sleeve, wherein the measuring bolts are circular truncated cone-shaped measuring bolts, and spherical outer measuring points are arranged on the tops of the measuring bolts. The hidden settlement observation point mark piece disclosed by the utility model is simple in structure and convenient to operate. When the hidden settlement observation point mark piece is used, the sleeve is connected with the measuring bolts through a screw thread, and the piece is observed and measured through special outer points. The sleeve can be further buried in a brick wall and concrete. The piece is extremely good in invisibility and not easy to damage. The sleeve and the measuring bolts are detachable. When the piece is used, partial measuring bolts can be cancelled. The piece is strong in universality, firm and reliable, and practical. After the piece is used, the measuring bolts are reversely screwed into the sleeve, so that the space is saved, and the spherical outer point is prevented from not being damaged.
Description
Technical field
The utility model relates to the measurement apparatus, is specifically related to a kind of observation station mark piece.
Background technology
Flourish along with national economic development, the engineering surveys such as covil construction, industrial building, skyscraper and deformation monitoring are increasing, and settlement observation point mark piece is as the most basic in Surveying Engineering and the deformation monitoring, the important symbol of permanent preservation is widely used, yet traditional settlement observation point mark piece uses inconvenience, and is disguised bad, fragile, and versatility is bad, and easily firmly loosening, impact detects effect.
The utility model content
Goal of the invention: the utility model provides hidden settlement observation point mark piece a kind of simple in structure, easy to operate, solid and reliable for problems of the prior art.
Technical scheme: for solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of hidden settlement observation point mark piece comprises sleeve and is installed in the interior survey bolt of sleeve; Described survey bolt is that circular platform type is surveyed bolt, and is provided with measuring point outside the sphere on the top of survey bolt.
Wherein, described sleeve and survey bolt are for being threaded, and the bottom of described survey bolt is provided with external thread, and the openend of described sleeve is provided with internal thread; Be threaded connection, solid and reliable being difficult for becomes flexible.
Wherein, the diameter of described sleeve is 20-24mm, and wall thickness is 2mm.The diameter that sleeve reasonably is set can be saved cost, reaches best observer state.
Wherein, the diameter of described spherical points outside is 18-20mm.The diameter that spherical points outside reasonably is set can improve observation effect and the interior protection of the sleeve of better packing into.
Beneficial effect: compared with prior art, the utlity model has following advantage: the utility model is simple in structure, and is easy to operate, sleeve is threaded connection the survey bolt in use, and spherical points outside observation is measured, and sleeve can also be embedded in brick wall and the concrete, disguise is namely good, and is also not fragile; Sleeve and survey bolt are detachable, and can also save part during use and survey bolt, highly versatile, solid and reliable, can also oppositely screw in the sleeve surveying bolt after practicality is complete, save the space, protect spherical points outside not to be damaged.
