Abstract
The utility model relates to a detection device of the construction field, in particular to a settlement observation positioning bar group, solving the problems in the prior art, for example, settlement observation points tend to be covered or discarded, which influences accuracy of detection value, which comprises an observation pole with a threaded hole on one end, an observation screw fitted with the thread and a forcing-off screw of a hexagon socket countersunk head cap screw, the forcing-off screw closes the port to prevent dust entering the port or man-made destroy of a port thread. An outer wall is provided with screw thread protrusion, so the observation pole is embedded in a structural entity more stably. A spherical cap is arranged on the non-threaded end of the observation screw. The utility model has the advantages of good protection effect on observation points, accurate measured value, simple processing, and low cost.
Description
Technical field
The utility model relates to a kind of building field pick-up unit, particularly a kind of settlement observation backstay group.
Background technology
In recent years along with the development of building industry, the raising that engineering process requires, it is elegant in appearance that exterior decoration is tending towards.Settlement observation point is essential as the necessary project of the engineering construction and the back settlement observation that is delivered for use.But adopt simple and easy coarse settlement observation point now in the engineering construction, affect in the exterior decoration construction of engineering later stage, the while covers the settlement observation point of former setting inevitably or scraps, and is bigger to the detection influence of settlement observation.
Summary of the invention
The utility model influences the problems such as accuracy of detected value in order to solve in the prior art settlement observation point and easily to cover or scrapping, and a kind of high settlement observation backstay group of accuracy of observing is provided.
The utility model is to adopt following technical scheme to realize: settlement observation backstay group is provided with the observation base bar of threaded hole by an end, and forms with the observation screw rod of its threaded engagement.
Settlement observation bar group described in the utility model is provided with the observation base bar of threaded hole by an end, and forms with the observation screw rod and the jackscrew of its threaded engagement.Jackscrew prevents dirt bits entry port or artificial destruction port screw thread with port closed.Outer wall is established the screw-like projection, makes the basic bar of observation implant infrastructure entity more stably.The non-threaded end of observation screw rod is provided with spherical caps.Jackscrew is a hexagon socket countersunk flat cap head screw.
The beneficial effects of the utility model are as follows: 1, effective to the observation station protection, measured value is accurate; 2, processing is simple, with low cost.

Among the figure: 1-observes basic bar, and 2-observes screw rod, 3-countersunk head jackscrew, 4-projection, 5-spherical caps.
Embodiment
In conjunction with the accompanying drawings embodiment of the present utility model is described further, present embodiment is to be used for illustrating of the present utility model, rather than the utility model is done any restriction.
Settlement observation backstay group is provided with the observation base bar 1 of threaded hole by an end, and forms with the observation screw rod 2 and the jackscrew 3 of its threaded engagement.Observe basic bar 1 outer wall establish screw-like projection 4.Observation screw rod 2 non-threaded ends are provided with spherical caps 5.Jackscrew 3 is a hexagon socket countersunk flat cap head screw.
Observe basic bar 1 adopt HRB335 Φ 25 or Φ 28 reinforcing bars, length is scraped in the hope of attractive in appearance to exposed parts according to demand processing in the actual engineering, and at the threaded hole of end processing M12 of scraping, the screw degree of depth 50～70mm.After the base bar machine-shaping, at body of rod port with the interior hexagonal countersunk head jackscrew 3 of corresponding 30～70mm with port closed, prevent dirt bits entry port or artificial destruction port screw thread, the back is installed observes at every turn and finishing using also in time with port closed.
During installation,, determine the position of observation station and the length of the basic bar 1 of observation according to the demand of buildings and furring.Specification pore-forming according to the settlement observation bar group base bar of selecting for use 1 is set at need on the structural solid at settlement observation point position, and dust in the hole is cleaned out.Adopt structure glue will observe on the basic bar 1 implant infrastructure entity, clean out, install back with supporting countersunk head jackscrew 3 closed ports.Take the certain protection measure after installing, can use after waiting for a week.
Earlier the sealing countersunk head jackscrew 3 of observation station port is back-outed during observation, the demand when measuring is installed observation screw rod 2, installs whether coaxial with the basic bar of observation 1 splash screw rod 2 at once, the accuracy of data when guaranteeing that observation detects.Standing up Sopwith staff after installing on the spherical termination of observation screw rod 2 can observe.After finishing, observation will observe screw rod 2 unload immediately, with countersunk head jackscrew 3 closed ports from observing basic bar 1.
