(3) periphery finished product protection: need, with multicolored cloth or plastic sheeting, factory building is safeguarded to wall, steel column, colored steel safeguard before construction, carry out finished product protection;
(4) location unwrapping wire, a side form: before installation form, should hang logical line, by logical line position, side template is placed in basic unit, tentatively fixes its position, with level gauge, check whether template top absolute altitude meets designing requirement, and check that whether template is straight, strictly control side form absolute altitude;
(5) concrete speading: concrete adopts jumping storehouse to build, constuction joint should arrange together in conjunction with shrinkage joint, short is every across formwork in each section, thereby accomplish every across concreting, after concrete strength reaches designing requirement, utilize the concrete surface build for the first time to carry out second this concrete building as the side form of concreting for the second time;
(6) concrete vibrating: concrete surface is vibrated, struck off and flattens with striking off the evener that vibrates;
(7) finisher is carried slurry troweling: when concrete is in critical initial setting time, adopt finisher repeatedly troweling, propose slurry, compacting, after often smearing and finishing for one time, after concrete surface moisture evaporate, beat and smear next time again;
(8) mechanical press polish: in strict accordance with pouring order of concrete, carry out floating, press polish, corner and local mechanical smear less than place by manually rubbing hair, press polish with the hands with machinery.
(9) maintenance: carry out maintenance after concreting 24h, take common covering, trickle or sprinkling to carry out maintenance;
(10) slot: on the concrete surface of having built perpendicular to concreting direction cutting machine joint-cutting.
Further improve technique scheme, concrete the paving of described step (five) adopts the method construction of longitudinal itemize, and longitudinally the width of itemize and partitioning slot, with wide, pave from end, when mixing concrete thing is poured in mould, discharging will be concentrated, and speed is slow, the empty thick template 2cm left and right that exceeds, carry out if desired material reducing or feed supplement work, vertical and horizontal section meets the requirements, and during spread concrete, should pave continuously, must not interrupt.
Further, during the operation of described step (six) evener, can by vibrating motor rotation direction, be drawn back and forth by operating personnel the drag cable that is located at evener two ends, concrete is vibrated and struck off, come and go vibration secondary, gait of march is controlled at 1-2 rice per minute, can reach requirement smooth and compacting.
Further, in described step (ten), the time of slot is to be that concrete crushing strength reaches 6～10MPa the suitable time.
Further, described step (ten) concrete operation method is as follows: on the cement concrete of intending joint-cutting, eject the line of ink marker, good and sound guide rail leading truck, joint cutter is located, start joint cutter, discharge water lubricated, rotating turret handle, slowly feed, adopt the thick diamond saw blade joint-cutting of 0.7mm, make saw blade first reach design seam dark, then screwing screw, pin screw mandrel and start walking, thereby forming the seam that the degree of depth is greater than 50mm, wide 0.8mm.
Compared with prior art, its beneficial effect is in the present invention: the construction method on Factory Concrete of the present invention ground, and easy construction, well-behaved science, the facility floor bearing capacity making by the method is high, is difficult for dusting.
