Description

Integral settlement observation nail capable of being connected secondarily

Technical Field

The utility model relates to the technical field of observation nails, in particular to an integral sedimentation observation nail capable of being connected secondarily.

Background

Sedimentation, particularly uneven sedimentation, of the construction works will lead to tilting, cracking, and even collapse of the building. Therefore, the settlement observation of the building engineering is an important deformation measurement work in the building construction and use process. National and industry related standard standards specify that settlement observation buildings should be subjected to settlement deformation observation during construction and use. At present, the settlement observation points are generally arranged on a bearing wall or a column of a building, one end of each settlement observation point is usually stuck by colloid or expansion nails to penetrate into and be fixed in the wall or the column, and the other end of each settlement observation point is exposed out of the wall surface and is used for a vertical ruler for settlement observation. The outside of the settlement observation nail adopts a protection box to protect and avoid damage.

Because settlement observation is performed through the whole construction stage and the use stage for a period of time in the future, the current common observation nails and protection boxes have the following defects:

many sedimentation observation nails are of fixed length, and the length cannot be changed during observation. The settlement observation point is generally installed immediately after the construction of a layer of bearing wall or column is finished, if the pre-buried observation nails are too long, the construction period is easy to touch and damage, and the observation cannot be continued; if the embedded observation nails are too short, after the outer wall heat insulation layer and the decoration surface layer are constructed in the later period, the sedimentation nails are wrapped in the heat insulation layer or the decoration layer, and the observation cannot be continued during the use period. Even if the individual length-adjustable settlement observation nails are connected by the screw-bearing parts of which the extension parts and the embedded wall parts are tightly abutted against 1cm-2cm, the deformation of the observation nail parts extending out of the wall is large, and the accuracy is difficult to ensure in the measurement work. In addition, protection box on the existing market is mostly fixed size, and the volume is great, and on the one hand damages easily, and on the other hand can't form effective connection with subside nail, unable normal play guard action.
