Steel tape for constructional engineering

Abstract

The invention discloses a steel tape for constructional engineering, and the steel tape comprises a steel tape body which is provided with a counting mechanism, a marking mechanism, and a speed control mechanism. The counting mechanism can directly read a measurement result, so that the reading is accurate, and misreading can be avoided; the marking mechanism can mark measuring points conveniently, accurately and clearly; the speed control mechanism can effectively control the speed of energy release of a clockwork spring, can slow down the retraction speed of the tape strip, protects fingers from being scratched, and prevents the internal structure of the steel tape from being damaged. A gradienter is also arranged, so that the levelness can be measured, and the working efficiency is improved; and a buckle and a lifting rope are arranged, so that carrying and using are convenient, and loss is prevented.

Description

technical field [0001] The invention belongs to the technical field of construction engineering measurement, in particular to a steel tape measure for construction engineering. Background technique [0002] Steel tape is a commonly used measuring tool in construction engineering, which is very helpful for project acceptance, project setting-out and project measurement. However, the existing steel tape needs to be manually read from the ruler strip, which is prone to inaccurate readings and misreading problems. Especially in construction projects, the ruler sticks out longer, which is more likely to cause misreading; The steel tape needs to be marked after measuring the length. Usually, a sharp object is used to scratch the wall to record. Not only is the mark easily lost, but the position of the mark is not accurate enough, which affects the quality of the project; The stored energy will be released instantly, causing the ruler to retract too fast, causing the ruler to boun...

However, the existing steel tape needs to be manually read from the ruler strip, which is prone to inaccurate readings and misreading problems. Especially in construction projects, the ruler sticks out longer, which is more likely to cause misreading; The steel tape needs to be marked after measuring the length. Usually, a sharp object is used to scratch the wall to record. Not only is the mark easily lost, but the position of the mark is not accurate enough, which affects the quality of the project; The stored energy will be released instantaneously, causing the ruler to retract too fast, causing the ruler to bounce, which not only easily cuts the user's fingers, but also easily catches other objects so that the ruler cannot be retracted, especially in construction sites. Places with more objects are more likely to be caught by other objects
