Construction method of irregular decorative column facing with variable cross section

The invention discloses a construction method of an irregular decorative column facing with a variable cross section. The method comprises a series of ordered construction and operation steps of paying off accurately throughcarrying out three-dimensional (3D) model building and 3D composing, accurately surveying and lining, positioning drill holes, nailing a wooden sleeper, producing and installing a wood frame, installing a composite board seal ring, paving a glass grid, leveling and painting a circular arc camber, composing the facing, positioning and snapping a line, and paving a face brick surface layer. The construction of the irregular decorative column facing with the variable cross section with low construction difficulty, ordered process and lower cost can be realized, a bowling type cylindrical deformed surface paved with wavy colorful patterns can be modeled, and the construction facing is smooth, the patterns can be connectedjoined smoothly, the radian feeling is good, and camber lines are smooth; furthermore, the decorative column is strong in modeling plasticity, easy to trim, reliable in quality and short in construction duration, the factory prefabrication of face bricks can be realized without the cutting again on the site, cost saving can be realized, and the patterns on the facing can be continuous uniform and corresponded continuously, uniformly and symmetricallycorresponding and symmetrical, therefore the perfect and uniform facing modeling effect can be reached.
