Abstract

The application relates to the technical field of building construction, and discloses a joint cutting device for building construction, the device comprises a turning plate, a linear sliding table, a moving plate, a hollow shaft, a rotating arm, a first spline shaft, a first spline sleeve, an electric push rod, a rotating shaft and a cutting piece. When the rotary cutting machine is used, the rotary shafts on the two sides are driven by external force to rotate, and then the cutting sheets on the two sides can be driven to rotate. And then the electric push rod is controlled to work, and along with the extension or retraction of the moving end of the electric push rod, the rotating arms at two sides can reciprocally rotate around the hollow shafts at two sides, so that the rotating shafts at two sides are driven to descend or ascend. Finally, the two side cutting pieces are driven to descend or ascend so as to cut or remove from the ground. A strip area convenient for impact breaking can be formed by one cutting stroke, so that the construction is convenient. And the linear sliding tables on the two sides are controlled to work, so that the moving plates on the two sides can be driven to move, and the distance between the hollow shafts on the two sides is changed. Finally, the spacing between the cutting sheets at the two sides is changed, so that the strip areas with different widths are cut.
