4) embedded U-shaped reinforcing bar positions；
5) binds inside reinforcing bar, branch inner side template and is reinforced with H200 type flitch back cord and back cord, and diameter 16mm is to drawing spiral shell
Bolt passes through PVC casing, and PVC outer tube is worked as thin-wall internal-mould plate and shored, and is used for the casing of split bolt, its sky is fixed in control
Abdomen and wall geometric dimension；
6) multi-cavity thin-wall slab reinforced concrete is poured, and using the symmetrical laminated pouring concrete of double duct, controls reinforcing bar
Concrete structure size.
Hard high density foam described in step 3), is the foamed polystyrene of 20-30kg/m3, and soft leather bound edge is 4mm
Polypropylene.
The spacing of U-shaped steel muscle described in step 4) disposes concrete cover according to depending on hard high density foam rigidity,
Every layer of hard high density foam and soft leather bound edge upper end are sealed using horizontally U-shaped reinforcing bar, hard when control concrete is poured
High density foam and soft leather bound edge are displaced up and down.
Internal model described in step 5) is shored, in addition to PVC outer tube before molding, the positioning of weld horizontal bar dowel, and length=wall
Thickness -1mm；It is welded into drum reinforcing bar control template position with pre-buried vertical dowel point, in two rows the center of main reinforcement point gear, Ying Xian
Four angles installation side of each cavity is rigidly in position, when dismounting extracts split bolt bar out.
The symmetrical laminated pouring concrete of double duct described in step 6) is using a diameter 100mm conveying steel pipe and to connect
Bifurcated makes steel pipe, that is, double duct by oneself perpendicular to two 80mm of thin-walled, and with symmetrical laminated pouring concrete, symmetrical laminated pouring can
Liner hard high density foam is avoided to be displaced.
Compared with prior art, the invention has the advantages that be not only simple it is practical, save working hour, cost is reduced, convenient for applying
Work.
