2) should conscientiously check before inner membrance is in place that base plate and girt strip cushion block of concrete bar protective layer the most all install；
3), after inner membrance is in place, should ensure that the size between inner membrance and girt strip, between inner membrance and inner membrance meets design requirement；
4, colligation fixing Anti-floating reinforcing steel bar；
1) Anti-floating reinforcing steel bar presses G-Design and layout；
2) Anti-floating reinforcing steel bar all should overlap at girt strip；
3) Anti-floating reinforcing steel bar is firm with falsework drawknot at girt strip and inner membrance gap location iron wire；
5, concreting；
1) concrete requires preparation according to design, stone and the medium sand that aggregate selects particle diameter to be 5～20mm, slump >=
180；
2), during casting concrete, first pour stigma and Vierendeel girder, then it is mixed to pour girt strip and floorslab concrete, girt strip and floor
Solidifying soil is carried out in a direction simultaneously；Should first fill interior intermembrane space during casting concrete and fill girt strip again, to guarantee that inner membrance gap size accords with
Close design requirement；Girt strip and two positions, inner membrance gap use two poker vibrators to vibrate simultaneously, it is ensured that base plate is closely knit.
The invention has the beneficial effects as follows:
1, inner membrance uses density more than 15Kg/m3 The solid polystyrene foam block of flame retardant type, its comprcssive strength meets coagulation
Pressure requirements when soil pours, will not damage rupture in work progress, it is to avoid occur that concrete infiltration is filled into the sky ruptured
Phenomenon in cavity configuration, reduces concrete amount, and cost of material of the present invention is low, reduces comprehensive cost.
2, flexible design is in addition to basic size, also can be nonstandard with on-site actual situations "one off" production different according to design drawing
Type inner membrance, solves top board boundary dimensions very well and does not fixes and special-shaped border inner membrance filling problem, and the scope of application is wider.
3, sound insulation, heat insulation employing density are more than 15Kg/m3 The solid polystyrene foam block of flame retardant type has good guarantor
Temperature, soundproof effect.
4, light weight inner membrance light weight, with 15Kg/m3 As a example by the solid polystyrene foam block of flame retardant type, single inner membrance group
Part weight is at about 2.3 3.1Kg, and during template support design, load can be disregarded, and on-the-spot transport is installed light, saves machinery, people
Expenses of labour is used.
5, construction is fast, duration short construction technology is simple, after floor bottom mould and reinforcing bar are completed, directly lays inner membrance,
Rear colligation Anti-floating reinforcing steel bar.After concreting, inner membrance combines with concrete, need not tear inner membrance open, the reduction of erection time,
Save material and labour cost.
