Cutting device for building construction

The utility model discloses a cutting device for building construction, and relates to the field of building construction. The cutting device for building construction comprises a supporting and fixing base, a clamping mechanism, a cutting machine and a clamping mechanism used for fixing a rotating roller. When the cutting device for building construction is used, firstly, the position of an object needing to be cut is fixed through the clamping mechanism, then the position of the cutting machine is adjusted through the clamping mechanism, then the cutting angle is adjusted, finally, the cutting machine is driven by the electric push rod to move downwards, and the object to be cut is cut; the cutting mode is simple and convenient, time and labor are saved, the accurate cutting angle of a cut object can be guaranteed through the arrangement of the angle positioning disc, and therefore the good material cutting effect in the building construction process is achieved. 本实用新型公开一种建筑施工用切割装置，涉及建筑施工领域。该建筑施工用切割装置包括支撑固定
