Description

Technical Field

[0001] This utility model relates to the field of engineering testing technology, and more specifically, to a device for detecting the spacing of steel bars in building bridge construction. Background Technology

[0002] A rebar spacing detection device for building bridges is a tool specifically designed to accurately measure and detect the spacing between rebars during the construction process. Its main function is to ensure the structural strength and safety of building bridges. If the rebar spacing does not meet the design standards, it may affect the load-bearing capacity and durability of the bridge. Therefore, the rebar spacing detection device plays a crucial role in building bridge construction.

[0003] In actual testing, the spacing of the steel bars protruding from both sides of the partition wall is measured, which makes it difficult to measure directly with conventional measuring instruments. Usually, it is necessary to measure the distance from the steel bars to the partition wall and the width of the partition wall, and then summarize the measurements. This not only makes the measurement steps cumbersome, but also further accumulates measurement errors, resulting in a large final detection error. Utility Model Content
