11.1.1, the side edge of the flat window is painted in place, the window frame is well installed, and foaming agent or cement mortar is filled densely;
11.1.2 the carbon silicon board is pasted on the front of the outer wall and is flush with the side of the windowsill, when the thin plastering surface layer is made, one layer of plastering mortar is firstly plastered until the edge of the window frame, when the whole large surface is hung with the mesh cloth, the mesh cloth is wrapped on the edge of the window frame before the mortar is not dried, and the mesh is pressed into the window frame without exposing the mesh; after the bottom layer mortar is dried, plastering the surface mortar for one to two times to flatten and straighten the window corner and the window side;
11.1.3 the construction unit of door and window is used to apply the sealant on the side of window frame and paint;
11.2, construction of the outer bay window part:
11.2.1 before two side edges of the bay window are constructed, a foaming agent or cement mortar is installed on a window frame and is filled compactly, and a wall body is painted in place;
11.2.2 before the carbon silicon boards are adhered, lines are well flipped at a position 10 cm from the side of the window frames at two sides, a package turning net is laid at the flipped lines, the width of the package turning is 20 cm, the package turning net is fixed at the basic level wall body by using plastering mortar, the net is not exposed, other parts are thrown out for standby, the carbon silicon boards are adhered to the positions of the flipped lines, the thrown grids are wrapped on the carbon silicon boards by using the plastering mortar, and then the cement mortar used by civil engineering units is immediately responsible for well powdering the gaps at the position 10 cm at the side edges; when the large-area net is hung after drying, smearing the plastering mortar to the edge of the window frame, hanging the grid cloth to the side edge of the window frame, pressing the grid cloth in without exposing the net, and after surface drying, smearing the plastering mortar for one to two times and flattening and straightening the whole;
11.2.3 setting a rigid bracket for each floor, wherein the rigid bracket must be treated with rust-proof treatment;
11.2.3 the door and window company seals the side of the door and window frame and applies paint.
