Detailed Description
The following examples are provided to further understand the present invention, not to limit the scope of the present invention, but to provide the best mode, not to limit the content and the protection scope of the present invention, and any product similar or similar to the present invention, which is obtained by combining the present invention with other prior art features, falls within the protection scope of the present invention.
Examples
A construction method of a decorative outer wall comprises the following steps:
s1, cleaning the base layer of the original cantilever structure by using an auxiliary tool, mainly removing floating slurry and other materials attached to the surface of the original cantilever structure, and leveling the local uneven base layer in a mode of chiseling, spot repairing and the like;
s2, determining the blanking height of the flat steel keel and the Ett plate according to the height of the suspensible part of the outer wall overhanging structure and the height difference between the suspensible part and the existing backfill soil, wherein the length of the Ett plate is ensured to be not less than 100mm and can be embedded in the backfill soil, and the length of the flat steel keel can be shortened by 50mm compared with each end of the length of the Ett plate; determining the blanking width of the Ett plate according to the width of the outer wall overhanging structure, and determining the number of flat steel keels according to the width of the Ett plate, wherein the transverse spacing of the flat steel keels is not more than 600mm in principle; the thickness of the flat steel keel is 2mm, and the thickness of the Egtel plate is 5 mm;
s3, determining the distance and the number of rows of the cement nails according to the existing height of the cantilever structure, wherein the cement nails are fixed on the Ett plate above the flat steel keel, and the vertical distance is 200 mm;
s4, uniformly pulling lines according to the heights and the lengths of different areas of the cantilever structure to determine the specific positions of the cement nails;
s5, cutting a groove at a backfill position below the Ether board at the periphery of the main building to ensure that the insertion of the Ether board into a soil body is not less than 100 cm;
s6, fixing the flat steel keel to an overhanging structure, and then fixing the Empedo plate by adopting a cement nail for auxiliary installation; the flat steel keel is fixed on the overhanging structure through expansion bolts, and the Ett plates are vertically fixed on the flat steel keel at intervals of 200 mm; the depth of the cement nail anchored into the concrete substrate is not less than 30mm, and the distance between the cement nail fixed on the flat steel keel and the Ett plate is not more than 200 mm;
s7, leveling to the original outer wall thickness by adopting anti-crack mortar, wherein the method is the same as the original outer wall construction method, but the positions of the anchor bolts are staggered with the positions of the flat steel keels; meanwhile, in order to avoid cracking at the splicing position of the ETT plate, glass fiber mesh cloth is adopted to reinforce the splicing position;
s8, spraying an outer wall decoration material to ensure that the overall appearance and effect of the outer wall are consistent;
