Wherein, in step (2), during installing bottom layer thin-walled light steel wall framework 8, skeleton bottom uses the leveling of mortar 11.
Wherein, in step (3), several symmetrical holes are drilled through on thin-walled light steel wall framework 8, it is symmetrical in hole
Wear template mortar pad 10；One end of the template mortar pad 10 is that the other end is iron wire 23 with ring-shaped groove 100；
The iron wire 23 of the template mortar pad 10 passes through the hole on thin-walled light steel wall framework 8, and in thin-walled light steel wall framework 8
It is bent downwardly, fixed form mortar pad 10.The advantages of template mortar pad, includes：Making is simple, cost is cheap；Template mortar
Cushion block rear molding has iron wire, the hole being drilled in advance through light steel skeleton, stoops iron wire and hangs up, installation rate is fast；Template mortar
The groove of cushion block, for the fixation of steel wire position, position is accurate, simple, installation rate is fast.
Wherein, in step (3), mortar chain link door window frame 7 is that door and window housing and steel wire are used together mortar and pour shape
Into prefabricated component, after intensity to be achieved, in-site installation is transported to；During installation, mortar chain link door window frame 7 is positioned over the light steel of thin-walled
In door-window opening under girder truss 25.Mortar chain link door window frame 7 and sash 27 are cast as one by mortar, are one pre-
Product.
Mortar chain link door window frame instead of door-window opening side template, and the installation of sash is synchronous complete with wall perfusion
Into；Solve the problems, such as the problem of sash side mould produces formwork added cost because of template size modulus, the engineering time is spun out,
Also solve the problems, such as that sash periphery is easily seeped water simultaneously.
Wherein, in step (4), the height of every layer of warming plate 13 is 1150mm~1200mm, upper and lower two layers of warming plate 13 it
Between be spaced 50mm, ensure that the outer screed of warming plate does not play drum, come off, fireproof partition can also be played a part of；Warming plate passes through
Warming plate drilling tail tapping screw 15 is fixed on the light wall skeleton 8 of steel 23 of thin-walled；The template sand in the outside of thin-walled light steel wall framework 8
Slurry cushion block 10 passes from warming plate 13；It is evenly distributed with warming plate 13 to wall penetration body screw sleeve 16.
In step (5), before plastic formwork is installed, the first reinforcing bar on wall both sides installation steel wire 19, steel wire 19
In the ring-shaped groove 100 of embedded template mortar pad 10；The steel wire 19 is cracking resistance galvanized steel wire netting；Both sides steel wire 19 it
Between diameter 4mm zinc-plated lacing wire is set away from 500mm up and down, between left and right；Prevent surface of wall from cracking；Warming plate is protected not produce
Life comes off.Appropriate distance between plastic formwork and steel wire is ensured using template mortar pad.
Transparent plastic film 24 is covered on the surface of plastic formwork 4 contacted with concrete, after form removable, transparent plastic is thin
Film is stayed on foam concrete metope, and because foam concrete has certain viscosity, transparent plastic film can stick in foam coagulation
On cob wall face, without adhesion plastic formwork,.Transparent plastic film plays a part of isolating with foam concrete, because foam mixes
Coagulating native additive has certain adhesion effect to plastic formwork, avoids foam concrete slurry adhesion template, reduces cleaning mould
The expense that the expense of labour of plate is used and template is lost, saved form oil caused by cleaning template surface, ensure that surface of wall
Smooth quality.Plastic sheeting is retained on metope after form removal, is kept the moisture inside wall to be not vaporized, is played foam coagulation
The maintenance action of soil, also reaches water-saving purpose.
Bulkhead formula vibrator 28 is provided with the plastic formwork 4.Its position placed synchronously is moved with wall pouring construction
It is dynamic：1) the part bubble pressed close near template surface layer is elapsed among foam concrete wall, the foam near template surface layer
Concrete density can increase, intensity improves therewith, and surface of wall intensity can improve 20%, enhance the breaking resistance of metope；2)
Increase the mobility of foam concrete, reduce hole and pitted skin inside foam concrete wall.
The supporting effect of building system of plastic template system and the present invention is good, and artificial branch, form removal are than traditional plank sheathing
Effect at least improves 50%, has reached reduction labour cost, accelerating construction progress, ensures the effect of quality.Building site neatly without timber,
Without landing ash, without building waste, small, the waste and old recyclable recycling of template, energy-conserving and environment-protective are influenceed on surrounding enviroment.
In step (6), the light steel floorboard of thin-walled emits girder steel 5 and is fixed on by drilling tail self-tapping screw 14 and cement fibrolite plate 6
Together；The spacing of the drilling tail self-tapping screw 14 is 300mm；Bottom thin-walled light steel wall framework 8 and upper 1~be less than 6 layers of thin-walled
Light steel wall framework 8 and ring beam reinforcing steel bar are wrapped to form firm structure node by pouring mortar collar tie beam 20.Floor emit girder steel, on
Firm connection between lower floor thin-walled light steel skeleton so that power transmission is uniformly reasonable between floor.Cement fibrolite plate is i.e. as bubble
The end template of foam concrete flooring is the ceiling in next layer of room again.
The setting of collar tie beam 20 has the effect that：
Upper vertical load more firmly and can be evenly transferred to lower floor by the 1, levels wall skeleton node connection；
2nd, it is beneficial to antidetonation, the wind loading rating for improving building；
3rd, crackle caused by differential settlement is reduced to occur；
4th, foam concrete wall pours respectively up and down by boundary of collar tie beam, avoids foam concrete area excessive, wall
Surface shrinkage cracks；
5th, large span door-window opening is met, collar tie beam increases arrangement of reinforcement as lintel；
6th, encorbelment sunshading board, small awning are met, increase arrangement of reinforcement is as antitorque beam；
In step (7), outer outrigger scaffold 3 is by the way that wall penetration body screw rod 26 is fixed；After outer outrigger scaffold 3 is removed, then
To placing diameter 6mm reinforcing bars 22 in wall penetration body screw hole 21, then UEA cement bonded sands are being filled to wall penetration body screw hole 21 is interior
Slurry, strengthen the globality (centre has warming plate to separate) of the foam concrete of wall both sides, also function to waterproof and compensation foam mixes
Coagulate the effect of the portion retracts of soil.Outer outrigger scaffold simple system, without traditional steel pipe scaffold, reduce construction cost and add
Fast speed of application.
Wherein, wall and the flooring foam concrete uses unit weight 1000kg/m3~1400kg/m3, intensity 4.9MPa~
10.9MPa；Using special foam concrete foamer, the indices for product of constructing meet《Foam concrete JG/T266-
2011》It is required that.
Using the technical parameter of foam concrete：
