After adopting the above structure, compared with the prior art, the utility model anchor bolt verticality inspection device has the following advantages: compared with the prior art, the verticality of the anchor bolts can be judged by directly observing the mercury bubbles on the level, so that the detection The accuracy is low and different. The utility model sets scale marks on the top surfaces of the upper horizontal angle steel and the lower horizontal angle steel. The plumb line formed by the thin line driven by sagging can accurately read the deviation value on the lower scale line. Just because the utility model directly sticks the vertical angle steel on the anchor bolt and measures the deviation value by reading the reading of the plumb line on the lower scale line, therefore, the utility model is very simple to operate. In addition, the upper horizontal angle steel, The lower horizontal angle steel and the vertical angle steel themselves are relatively strong, and they are also very durable compared to the prior art after they are connected.

The setting of the handle makes the utility model very convenient to carry.

Two sets of upper scale lines and two sets of lower scale lines are convenient for inspectors to read the values. In other words, when inspectors are measuring the verticality of anchor bolts, if one of the scale values is blocked by other things, the inspectors will Another set of scale values can be read.

The 500mm distance between the upper horizontal angle steel and the lower horizontal angle steel can ensure the best detection accuracy under the condition that the weight of the utility model is suitable. As we all know, if the distance between the upper horizontal angle steel and the lower horizontal angle steel is larger, the height of the vertical angle steel will be higher, and the corresponding weight will be heavier.
