Built-in type building settlement observation nail

Abstract

The invention discloses a built-in type building settlement observation nail. The built-in type building settlement observation nail comprises a sleeve, a guide rod and an built-in measuring nail, wherein the sleeve is a semi-closed structure, the guide rod can slide inside the sleeve, and the built-in measuring nail is accommodated in a C-shaped groove in the middle portion of the guide rod. After the built-in building settlement observation nail is inserted into a wall and a column to reach a scale line, and the length of a portion remaining outside the wall and the column is only 3cm, so that the observation nail can be effectively prevented from being manually damaged or deformed. When in measurement, the built-in measuring nail can be withdrawn from the sleeve, so that the measuring nail is ensured to have sufficient length to provide a large space for setting a leveling rod, thereby eliminating errors generated in the measuring process, and obtaining accurate data.

Description

technical field [0001] The invention relates to the field of building measurement, in particular to an inward-facing building settlement observation nail. Background technique [0002] In high-rise building engineering, with the increase of upper floors, building settlement deformation begins to develop gradually, which requires long-term and accurate monitoring of building settlement to ensure the safety of high-rise buildings. In the existing building settlement measurement, an L-shaped measuring nail is often driven into the wall and column as the measuring point for measurement. However, the length of this measuring nail is limited, and there is more space for erecting the leveling rod after being driven into the wall. Small, it will be difficult to measure the ruler, which will have a great impact on the accuracy of the obtained data. Moreover, the environment of the construction site is relatively complex, and the construction personnel have insufficient understanding...

Problems solved by technology

In the existing building settlement measurement, an L-shaped measuring nail is often driven into the wall and column as the measuring point for measurement. However, the length of this measuring nail is limited, and there is more space for erecting the leveling rod after being driven into the wall. Small, it will be difficult to measure the ruler, which will have a great impact on the accuracy of the obtained data

Moreover, the environment of the construction site is relatively complex, and the construction personnel have insufficient understanding of the role of measuring nails, resulting in a large number of measuring nails being artificially damaged or deformed during the long-term monitoring process, resulting in the lack of settlement data, which cannot accurately reflect high-rise buildings The real situation of subsidence
