Purpose of the invention: The purpose of this utility model is to provide a portable beam width measuring tool with simple structure, convenient operation and high precision for the deficiencies of the prior art. The tool can be used to accurately check the beam width and avoid mistakes.

Technical solution: A portable beam width measuring tool described in the utility model includes a handle, a connecting arm and a measuring ear, the connecting arm is placed between the handle and the measuring ear, and the handle and the measuring ear are connected as A whole body; a certain angle is formed between the handle and the connecting arm, and a 90° angle is formed between the connecting arm and the measuring ear;

The measuring ear is a rectangular plate with several layers of stepped notches at any lower corner position, each notch is marked with a scale, and the scale is based on the side without notch on the measuring ear as the zero point.

Further, in order to facilitate on-site construction operations, an angle of 90° is formed between the handle and the connecting arm.

Further, the stepped notch is a two-layer stepped notch.

Further, in order to ensure that the standards of each detection are consistent and improve the detection accuracy, the height of each step of the step-shaped notch is the same.

Further, the length of the notch at the bottom of the ladder-shaped notch is the largest, and the notch at the highest level is the smallest.

Further, the connecting arm is connected to the side of the measuring ear without a notch, and the measuring range of the measuring ear is L≤500 mm.

Further, the connecting arm is arranged on the vertical line of the measuring ear, and the measuring range of the measuring ear is 600mm≤L≤800 mm.

Further, in order to improve the structural stability of the testing tool, the handle, the connecting arm and the measuring ear are integrally formed.

Beneficial effects: (1) The tool is easy to manufacture and easy to carry. During the measurement process, the process of taking a point and squatting down to measure it with a ruler is avoided. When measuring, you only need to insert the measuring ear with the scale engraved into the beam, which can be seen intuitively. The deviation of the beam width can be accurately detected, and the workload is reduced while the accuracy is high; The extracted questions minimize the measurement error.

detailed description

The technical scheme of the utility model will be described in detail below with the accompanying drawings, but the protection scope of the utility model is not limited to the described embodiments.

Embodiment 1: An integrated portable beam width measuring tool, including a handle, a connecting arm and a measuring ear, the connecting arm is placed between the handle and the measuring ear, and the handle and the measuring ear are connected into one Overall; the handle and the connecting arm are at an angle of 90°, and the connecting arm and the measuring ear are at an angle of 90°;

The measuring ear is a rectangular plate with two layers of stepped notches at any lower corner position, and each notch is marked with a scale in the horizontal direction. The scale length of the actual mark on one layer is 100mm. In order to ensure the consistency of the standard for each inspection and improve the detection accuracy, the height of each step of the stepped notch is the same, and the notch at the bottom of the stepped notch has the largest length. The notch at the highest level has the smallest length. In this structure, the connecting arm is connected to the side of the measuring ear without the notch. The two-layer stepped notch can measure beam widths of 300mm, 400mm and 500mm in turn.

When using the above tool to measure the beam width, hold the handle 1 directly and place the tool on the beam directly, so that the beam deviation can be read out conveniently, avoiding the large deviation of the beam width in the existing point-taking and squatting measurement method. Large points may not be able to be extracted, and the measurement error will be minimized; as shown in Figure 2~4, when using this device to detect a beam with a width of 400mm, place the tool on the beam, and Figure 2 shows that the beam width has no error Figure 3 is a diagram with a smaller beam width, and Figure 4 is a diagram with a larger beam width.
