Description

Technical Field

[0001] The utility model belongs to the technical field of thickness measuring devices, and in particular relates to a device for measuring the horseshoe chamfer size and web thickness of a T-beam. Background Art

[0002] When a highway project is handed over for acceptance, the structural dimensions of the T-beam need to be measured. During the construction process, the cross-sectional dimensions of the T-beam need to be measured and controlled. Among the structural dimensions, the web thickness and horseshoe chamfer are difficult to measure.

[0003] After searching, the Chinese patent with the existing patent number: CN215003454UT discloses a T-beam web measuring device, including a base frame and at least one pair of oppositely arranged columns, the axis of the column can be perpendicular to the base frame, the columns are arranged on the same side of the base frame, there is a spacing between each pair of the columns, and the columns are provided with distance measuring elements, and the distance measuring elements on each pair of the columns are arranged oppositely. When measuring with the T-beam web measuring device provided by the utility model, the base frame is first contacted with the bottom end of the T-beam, and the two columns in each pair of columns are respectively located on both sides of the T-beam web, and then the distance between the column and the surface of the T-beam web is measured using the distance measuring element. The difference between the distance between the two columns minus the measured values ​​of the two distance measuring elements is the thickness of the T-beam web. During the measurement process, no additional tools are required, and only one person is required to fix the base frame and the T-beam relatively, which is convenient to operate and has a fast measurement speed.

[0004] However, the above method for detecting the horseshoe chamfer size and web thickness of the T-beam can only measure the chamfer width and height through the coordinated measurement of the level ruler and the steel ruler. The measurement process not only requires the cooperation of two people, but also requires that the level ruler and the steel ruler be perpendicular to each other, which makes the process difficult.
