And binding measure；
2) concrete batching；
3) concreting: successively pouring, and one-time-concreting molding, concreting is pumped using automobile, first by one
Concrete is divided to inject girt strip, marginal not enters side and vibrates, and injects the height of girt strip concrete in 200mm or so, first with a dedicated vibration
Dynamic stick vibrating casting concrete first allows a part of mortar to penetrate into core model bottom by vibration, and closely knit bottom surface makes cracking resistance panel and bottom
It penetrates into mortar to organically combine, forms smooth bottom surface, pour direction of propulsion and carried out by easy stages along girt strip axis direction；
Wherein, pouring out concrete uniformly should prevent from accumulating excessively high and damaging steel mesh and engrave, using the sphere of action of vibration, make
Concrete gets into steel mesh and engraves bottom, guarantees that lower concrete mortar penetrates into and steel mesh engraves the closely knit of bottom, avoids vibrating head direct
Vibration steel mesh is engraved；
4) vibrating time is held, prevents from excessively vibrating: firstly, observed during girt strip concrete vibrating when vibrating,
It observes by the naked eye steel mesh and engraves bottom, when lower concrete has penetrated into or should stop shaking immediately close to penetrating into when steel mesh engraves bottom
It smashes, avoids the infiltration for excessively vibrating and causing concrete, inject concrete to top flange panel, the height of injection to girt strip again later
Degree meets the requirement of design plate thickness；
5) concrete curing: concrete curing is covered using gunnysack or plastic film, keeps concrete surface wet, in case of
The wet waterside number of hot weather is increase accordingly, interior for 24 hours after the completion of concreting to avoid people, upper object on concrete；
6) demoulding: concrete reaches the intensity i.e. collapsible die of construction demoulding requirement through conserving.
Preferably, it during step 3) casting concrete, avoids directly bearing against construction equipment into steel mesh and engrave, construction behaviour
Making personnel should construct on girt strip reinforcing bar, avoid directly trampling steel mesh and engrave and roof steel bar.
Preferably, in step 4), when vibrated concrete, should use diameter to shake for the vibrating head or plate of Φ 30 or Φ 50
Movable plate.
Preferably, engineering floorboard uses gunnysack covering curing, roof boarding plastic covering membrane curing after levelling.
Preferably, concrete slump control is in 200mm ± 20mm, and concrete gravel size controlling is between 10-30mm.
Compared with prior art, the beneficial effects of the present invention are:
The present invention can be improved the intensity of concrete and can satisfy the requirement of hollow floor, in addition, using this hair
The engineering floorboard and roof boarding that casting in open is built have better waterproofness and crack resistance, have the advantages that long service life, the present invention
Process flow it is simple, technical process is easily controllable.
