the method comprises the steps of firstly, emitting a horizontal control line and a vertical control line on a wall body, and then emitting a plate block arrangement line of the curtain wall plate according to the lofting design of the curtain wall and by combining the changing position, elevation and changing characteristics of the vertical face of the curtain wall. According to the on-site situation after paying off, measuring the actually constructed civil structure, and processing the position with large error and needing to be adjusted;
step two, mounting a fixed steel plate according to the positioning paying-off and design interval of the square steel, fixing the fixed steel plate on the wall body through expansion bolts, checking the tightening force of the bolts and the nuts by using a torque wrench after the mounting is finished, and fixing by spot welding;
determining the positions of the first supporting piece and the second supporting piece according to the vertical control line, spot-welding the first supporting piece and the second supporting piece on a fixed steel plate during construction, checking three-dimensional errors of the first supporting piece and the second supporting piece one by one, and fully welding and fixing the first supporting piece and the second supporting piece after the three-dimensional errors are checked and adjusted to be qualified;
after the fixed steel plate, the first supporting piece and the second supporting piece which are installed are checked and accepted, performing anti-corrosion treatment on the welding position;
constructing a heat insulation layer on the cleaned wall, wherein the installation of the heat insulation plate is determined according to different projects and requirements thereof, but the heat insulation plate must meet the acceptance and acceptance criteria of construction quality of building energy-saving projects (GB 50411-2007);
step four, mounting the triangular keels on the first fixing sections and the second fixing sections of the outer ends of the first supporting piece and the second supporting piece through bolts, and checking the tightening force of the bolts and the nuts by using a torque wrench after the mounting is finished;
and step five, cutting the curtain wall board, and performing 45-degree cutting treatment on the opposite angle of the curtain wall board at the internal corner of the curtain wall.
Sliding the outer ends of the hidden frame keels into mounting grooves formed in the inner plate surface of the curtain wall plate, and mounting four hidden frame keels on the inner plate surface of each curtain wall plate;
hang the curtain board on triangular keel through dark frame fossil fragments, from the successive layer installation from bottom to top, adjust the board after the board of curtain board is first adorned and is accomplished, through the roughness and the straightness that hangs down of adjustment curtain board, guarantee that the curtain board is violently flat vertical. The size of the gap meets the requirements;
and seventhly, directly cleaning with clear water after construction is finished, cleaning a local polluted part by using a cotton cloth dipped with a dimethylbenzene solvent, cleaning with a short brush when objects such as mortar are sprayed on the curtain wall board and are close to dry, cleaning with clear water, and directly polishing with hard objects such as sand paper and the like so as to avoid damaging a self-cleaning layer of the curtain wall board.
