[0002] During the decoration process of a building, it is necessary to measure the building corner angle in order to adjust the size of the decoration materials. Common building angles are right angles, and the less common building wall angles are arc angles. In the process of measuring the central angle corresponding to the building arc angle, the existing measurement method usually uses a straight line to first measure the chord length and chord height of the arc angle, then use a ruler to find the midpoint of the chord length, and finally use a pencil to draw the arc radius on the construction ground, and then use a protractor to measure the size of the central angle. The existing measurement method has the problems of cumbersome operation steps and low accuracy, which can easily lead to a prolonged measurement period. For this reason, we propose a building corner angle measurement device that can shorten the measurement period and improve the measurement accuracy. Utility Model Content
