Composite thermal-insulating wall of the present invention can adopt following scheme construction:
Construction sequence is following:
Step 1, at the opposite face of two load-bearing pillars 1; Respectively weld a vertical angle steel 17 along the inside edge; Weld a horizontal corner steel 18 respectively in the lower surface of last collar tie beam 2 and the upper surface of lower ring beam 24; Vertical angle steel 17 on the load-bearing pillar 1 and the horizontal corner steel 18 on the last lower ring beam constitute the fixed frame 10 of interior wall flaggies 4, and along continuous straight runs is every fixed frame 10 in vertically is provided with a web towards outdoor T-steel 12 at a distance from 400mm-600mm, the two ends of T-steel 12 respectively with last lower ring beam on horizontal corner steel 18 weld; Constitute the skeleton II 11 of interior wall flaggy 4, the T-steel 12 in the skeleton II 11 is separated into multiple row concrete slab draw-in groove with fixed frame 10;
Step 2, at the opposite face of two load-bearing pillars 1; Respectively weld a vertical angle steel 17 along outer ledge; Weld a horizontal corner steel 18 respectively in the lower surface of last collar tie beam 2 and the upper surface of lower ring beam 24; Vertical angle steel 17 on the load-bearing pillar 1 and the horizontal corner steel 18 on the last lower ring beam constitute the fixed frame 10 of exterior wall flaggies 3, and along continuous straight runs is every fixed frame 10 in vertically is provided with a web towards indoor T-steel 12 at a distance from 400mm-600mm, the two ends of T-steel 12 respectively with last lower ring beam on horizontal corner steel 18 weld; Constitute the skeleton I 9 of exterior wall flaggy 3, the T-steel 12 in the skeleton I 9 is separated into multiple row concrete slab draw-in groove with fixed frame 10;
Step 3, on the web of the T-steel of skeleton I 9, vertically whenever a support bar 15 is installed at a distance from 600mm-800mm, the other end of support bar 15 is connected with the web of the T-steel of skeleton II 11;
Step 4, choose a block concrete plate, make cementing agent with cement mortar, concrete slab is installed in the row concrete slab draw-in groove in the skeleton I 9, the perpendicular end surface of concrete slab is attached on the web of T-steel, with anchor clamps 26 concrete slab and skeleton I 9 is clamped;
Step 5, choose a block concrete plate; Make cementing agent with cement mortar; Concrete slab is installed in the row concrete slab draw-in groove in the skeleton II 11; And a block concrete plate that installs with above-mentioned steps four is relative, and the perpendicular end surface of concrete slab is attached on the web of T-steel, with anchor clamps 26 concrete slab and skeleton II 11 is clamped;
Step 6, between two relative concrete slabs that step 4 and step 5 have installed, a support bar 27 is set, two concrete slabs that are oppositely arranged are fixed on the wing plate of corresponding T-steel, after take off the anchor clamps on the two block concrete plates;
Step 7, according to the method for step 4, in the adjacent row concrete slab draw-in groove of the level of the concrete slab that skeleton I 9 has installed, a block concrete plate is installed again; According to the method for step 5, in the adjacent row concrete slab draw-in groove of concrete slab level that skeleton II 11 has installed, a block concrete plate is installed again; Between two relative concrete slabs, a support bar 27 is set, two concrete slabs that are oppositely arranged are separately fixed on the wing plate of corresponding T-steel, after take off the anchor clamps on the two block concrete plates;
Step 8, according to the method for step 7, on skeleton I 9 and skeleton II 11, block-by-block is accomplished the installation of delegation's concrete slab in regular turn, fills up the slit between each concrete slab with jointing cement mortar 19;
The step of step 9, repeating step four to step 8; On skeleton I 9 and skeleton II 11; Block-by-block is installed concrete slab line by line in regular turn; Skeleton I 9 last column concrete slabs are mounted to the lower surface of collar tie beam 2, reserve the high sprue gate of 100-200mm 40 between interior wall flaggy 4 last column concrete slabs and the last collar tie beam 2, dry 24-48 hours;
Step 10, cast foam concrete insulation layer: by every cubic metre of consumption; Get the cement of 168-360kg, the flyash of 0-144kg, the blowing agent of 0.25-0.32kg and the water of 140-198kg, after mixing, process the foam concrete pours; Pour into the foam concrete pours from the sprue gate of interior wall flaggy 4; Irritate to the space of filling up between exterior wall flaggy 3 and the interior wall flaggy 4, dry 12-24 hours, form foam concrete insulation layer 5;
Step 11, with the space between foam concrete filling block 16 filled and process concrete heat-insulating layers 5 and interior wall flaggy 4 and last collar tie beam 2 bottom surfaces;
Cement sand plaster is used on the surface of step 12, difference external wall board layer 3 and interior wall flaggy 4, forms wall face plastering mortar layer 6 and interior metope plastering mortar layer 7, accomplishes the construction of heat-preserving wall.
Described foam concrete filling block 16 adopts with foam concrete insulation layer 5 same foam concrete pours to be processed.After filling foam concrete pours and drying between external wall board layer 3 and the interior wall flaggy 4, fill in foam concrete filling block 16, the cavity in the body of wall is filled up from sprue gate along the strip of collar tie beam setting.
