Problems solved by technology

According to the requirements of national engineering survey regulations, for high-rise buildings, bridges, dams and other projects, it is necessary to embed several permanent signs for settlement measurement on the surrounding walls. The traditional observation signs are relatively simple and buried with steel bars. On the wall, one end is exposed for inspection. The disadvantage of this method is that the exposed part is prone to displacement or damage, and it also affects the appearance

Abstract

The invention discloses an L-shaped settlement marker. The L-shaped settlement marker is mainly composed of a marker rod of a settlement observation marker and a circular observation head arranged on the top of the marker rod, wherein the top of the circular observation head is provided with an observation point; the marker rod is connected with a main rod through a 90-DEG bend; the tail part of the main rod is provided with retaining knurled threads; and the end part of the main rod is a flattened positioning head. The L-shaped settlement marker is applicable to settlement observation of a variety of buildings, bridges, roads, subways and the like.

Description

technical field [0001] The invention relates to an L-shaped observation mark for measurement. Background technique [0002] In large buildings, such as high-rise buildings, bridges, etc., its safety is very important, and it is related to a century-old project, so it is necessary to regularly detect the settlement of the building. According to the requirements of national engineering survey regulations, for high-rise buildings, bridges, dams and other projects, it is necessary to embed several permanent signs for settlement measurement on the surrounding walls. The traditional observation signs are relatively simple and buried with steel bars. On the wall, one end is exposed outside for inspection. The disadvantage of this method is that the exposed part is prone to displacement or damage, and it also affects the appearance. Contents of the invention [0003] The object of the present invention is to provide a settlement observation mark for measurement with reasonable de...
