Description

Technical Field

[0001] The utility model relates to a settlement observation mark, in particular to an L-shaped settlement observation mark which is not easy to loosen. Background Art

[0002] Settlement observation refers to the measurement of the elevation change of the observed object. By comparing the differences between the current data, the previous data, and the first data, the settlement rate, settlement amount, and settlement difference of the observed object are calculated, and the foundation tilt, local tilt, relative bending, and component tilt indicators are calculated as needed to determine whether the observed object is safe.

[0003] Settlement observation must be carried out throughout the entire construction phase of the building and continue into the operational phase until the observed object reaches the stability standard.

[0004] Therefore, during the entire settlement observation process, the relative relationship between the monitoring point and the observed object is required to be stable. If the monitoring mark becomes loose during the process, it will be impossible to determine whether the monitored object is safe and calculate the cumulative settlement amount.

[0005] After years of use, it was found that this type of observation mark is prone to loosening during use, causing inconvenience to the measurement work. Utility Model Content

[0006] The utility model aims to provide an L-shaped settlement observation mark which is not easy to loosen, so as to solve the disadvantage that the circular observation nail in the prior art is unstable.

[0007] The utility model is implemented by adopting the following technical scheme: an L-shaped settlement observation mark which is not easy to loosen, characterized in that it includes an observation head and a support rod, wherein the observation head is arranged at one end of the support rod, and the other end of the support rod is inserted into the installation hole during installation, and the cross-sectional shape of the support rod is a non-rotating cross-sectional shape.

[0008] Furthermore, the support rod is L-shaped, and the support rod includes a marking rod and a fixing rod.

[0009] Furthermore, the sign pole and the fixing pole are perpendicular to each other and integrally connected.

[0010] Furthermore, the observation head is fixedly connected to one end of the sign pole.

[0011] Furthermore, the fixing rod is provided with a knurled surface.

[0012] Furthermore, the knurled surface is completely inserted into the mounting hole during installation.

[0013] Furthermore, the L-shaped settlement observation mark is fixedly connected to the mounting hole by anchoring glue during installation.

[0014] The utility model discloses an L-shaped settlement observation mark which is not easy to loosen, and its beneficial effects include: by changing the circular cross-sectional shape of the existing L-shaped settlement observation mark, the defect of the instability of the circular observation nail is solved, so that the settlement observation data is more reliable.
