Step 5, hydroelectric facility pipeline (4) pre-buried and fixing: carried out the installation of hydroelectric facility pipeline before the wall panel of mating formation, hydroelectric facility pipeline is fixed between adjacent centre keel, line box and lightgage steel joist are connected and fixed, and at the relevant position of panel reserving hole, line box flushes with panel, stagger in the position of hole and centre keel, cross-arm keel are installed in online box below;
The installation of basic unit's panel outside step 6, lightgage steel joist: panel is successively installed from bottom to top, first installs in the outside of lightgage steel joist the exterior sheathing that first floor panel is built as body of wall layering initial period, and panel and lightgage steel joist carry out anchoring;
The installation of basic unit's panel inside step 7, lightgage steel joist: the inner formword of the first floor panel of mating formation in the inner side of lightgage steel joist during as body of wall placement layer by layer, wherein, panel is no longer established and directly using frame column as inner formword in the surface of frame column that embeds infilled wall inside;
The floating shutoff of step 8, hole and plate seam: the plate seam on mounted both sides panel (21) and frame beam plate rod structure face are connected to gap clay carry out shutoff with the panel of inner formword; Build front inspection window and strengthen the airtight situation of gap plugging of keel and panel, also can adopt polyurethane foam glue to play glue processing in inner side;
Building of step 9, light porous inorganic core material (22): build light porous inorganic core material between inner and outer template, adopt placement layer by layer method, build for every layer and be highly not more than 600mm, be not less than 2 hours the interval time that two-layer light porous inorganic core material is built;
Step 10, other deck panels are installed and build light porous inorganic core material from bottom to top: carry out the method according to step 6～ten, other deck panels are installed from bottom to top and carry out the placement layer by layer of light porous inorganic core material, complete until build all, now, light porous inorganic core material and lightgage steel joist are condensated as a whole, there is no seam and tie point, form good rigidity external wall system;
Installation and the construction of step 11, window structure (7): adopt aluminium alloy window frame to make window frame, four limit esconsons all have fixing hole, every 300～500mm spacing, utilizing electric drill to pierce headed self-tapping self-drilling screw nail is fixed on window frame to strengthen on keel (5), strengthen adopting thermal insulation foaming glue (10) sealing between keel (5) and window frame, thermal insulation foaming glue (10) flushes with window frame edge after repairing;
The sticking construction of step 12, canvas cloth (8): breathable waterproof cloth is pasted in border inside window frame, paste airtight canvas cloth in border, outside, canvas cloth is the wide rolling of 80mm, carry the wide adhesive area of 20mm along long limit one side, be used for the window frame of aluminium alloy bondingly, other non-adhesive areas are smeared after building adhesive bonding tight with body of wall;
After step 13, quality inspection, hidden acceptance(check), carry out outer lateral layers decoration construction in window, construction completes.
10. the construction method of the energy-saving heat preserving of light inlet window according to claim 8 structure, it is characterized in that: in described step 12, on the surface layer of canvas cloth (8), extrude the concavo-convex netted of rule, the combination of the receipts face such as be conducive to plaster, closing in material, increases surface roughness.
