Easy-to-detach construction site temporary housing structure

The invention relates to an easy-to-detach construction site temporary housing structure which comprises a plurality of stand columns vertically arrayed at equal intervals. Wall boards with the same height as the stand columns are clamped between the adjacent stand columns. Clamping pieces protrude out of the side faces, perpendicular to the ground, of the wall boards. Clamping grooves for clamping the clamping pieces are formed in the side faces, facing the wall boards, of the stand columns. Long-strip-shaped sealing strips horizontally slide in the clamping grooves and are located on the sides, away from the wall boards, of the clamping pieces and matched with the sections of the clamping grooves. The stand columns are hollow and are internally rotationally connected with a plurality ofcams. The cams abut against the sides, away from the clamping pieces, of the sealing strips. A roof or floor is in lap joint with the upper sides of the wall boards jointly and is fixedly connected with the wall boards. Throu
