Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, and more specifically, to a measuring ruler for building construction. Background Art

[0002] The quality of construction projects refers to the comprehensive requirements for the safety, applicability, economy, environmental protection, aesthetics and other characteristics of the project in the current national laws, regulations, technical standards, design documents and contracts. The quality of construction is more important than Mount Tai and is related to the safety of people's lives and property. Therefore, construction quality inspection is a relatively important project in construction projects. In the process of construction quality inspection, various inspection instruments are often needed. The most common one is the inspection ruler. The existing inspection ruler is a long ruler with readable marks on it. Then the inspectors hold the inspection ruler to measure and inspect various data of the building.

[0003] In order to improve the detection range of the measuring ruler, an extension ruler is generally slidably arranged inside the existing ruler. However, the slidingly connected extension ruler is easily affected by friction, which makes it very inconvenient to extend and retract it, or even get stuck. At the same time, the slid-out extension ruler can only measure in the same direction, but cannot measure multiple points in the vertical direction, which reduces the practicality of the extension ruler. At the same time, it is not convenient to read the indication of the measuring ruler when the sight is dim, and the marking pen on the measuring ruler is easy to lose, which reduces the adaptability of the measuring ruler.
