Description

Technical Field

[0001] The utility model relates to the technical field of concrete detection, in particular to a multifunctional detection ruler. Background Art

[0002] Concrete, referred to as "concrete", is a general term for engineering composite materials that are bonded into a whole by cementitious materials. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates; mixed with water in a certain proportion and obtained by mixing, cement concrete is also called ordinary concrete. With the continuous development of the economy, many parts of my country are vigorously developing urbanization construction. In this process, reinforced concrete has played an important role. However, in the process of construction, reinforced concrete often causes internal structural defects due to various reasons, so it must be tested before use. Therefore, concrete testing devices are needed.

[0003] At present, the traditional method for detecting the thickness of concrete pouring on the construction site is to weld a short transverse steel bar on the J-shaped steel bar. The distance between the transverse steel bar and the bottom of the steel bar, i.e. the thickness of concrete pouring, cannot be flexibly adjusted to meet the needs of different concrete thickness detection. In addition, inaccurate measurement values ​​will directly affect the accuracy of subsequent concrete processing, greatly reducing the quality of concrete. Therefore, we propose a new type of multi-functional detection ruler. Utility Model Content
