Auxiliary cutting device for building construction and using method thereof

The invention relates to the technical field of building construction, in particular to an auxiliary cutting device for building construction and a using method of the auxiliary cutting device for building construction. A first angle encoder and a distance sensor are used for measuring the change of the relative position between the detection probe and the supporting rod and transmitting a detection signal to a control system for processing, and then a processor of the control system is used for respectively controlling a first stepping motor and a second stepping motor of the cutting mechanism to work; therefore, the high-pressure water jet cutter can simulate the motion trail of the detection probe, the shape of the material needing to be cut can be accurately determined, the shape of the material is matched with the shape of the area to be laid, the cutting accuracy is effectively guaranteed, and waste of the material in the cutting process can be greatly reduced. 本发明涉及建筑施工技术领域，尤其涉及一种建筑施工用辅助剪裁装置及其使用方法，通过设置
