(2) sheet steel tape system is installed：With plastic housing interpolation steel plate combination steel tape, the spacing in channel-section steel template
30-50cm installs plastic housing and steel tape, and is fastened with self-tapping screw, and plastic housing is embedded into concrete when pouring,
After form removable, steel tape is inserted at the reserved hole of plastic housing；
(3) flush type metal transmission rod and steel tape system are installed：In passageway and passage junction, due to frequency of use compared with
Flush type transmission rod, so installing flush type metal transmission rod and steel tape system herein, is welded and fixed by height during pouring construction
On 10# channel-section steels, while adjusting transmission rod upper surface absolute altitude with spirit level, make it consistent with terrace absolute altitude；
(4) terrace is flattened, leveling ruler is scraped using high-flatness indium steel and strikes off：Employ three kinds of high-flatness scrapes leveling ruler, just
The flat stage scrapes leveling ruler progress both sides using double hand-held and struck off, and apparent surface laitance situation during striking off is clear by unnecessary laitance
Third time is carried out after removing to strike off；The cambered surface indium steel of one man operation is scraped leveling ruler using belt length and struck off for three times in length and breadth by the receipts face stage, receives
Face essence flat stage scrapes leveling ruler using the square indium steel of one man operation and struck off for twice；
(5) concrete curing：Start within 6-8 hours after the completion of the receipts face essence flat stage after being cast thin with sprayer water spray covering
Film, then add one layer of maintenance geotextiles to carry out curing concrete 14 days, it is final to ensure ultra-flat terrace surface layer without transverse crack；
(6) LCM is constructed：The receipts face flat staged construction of essence is completed 14-21 days, and progress is uniformly sprayed at sprayer
On ready-made ground, curing agent is pushed away even with mop, its naturally osmotic is then allowed, started after 4-5 hours with narrow fabrics cushion
Sanding machine is processed by shot blasting, plays a part of sealing and curing terrace concrete topping；
(7) flush type metal transmission rod treatment of construction joints：After 1 month, due to temperature change, two panels steel plate is drawn
Open, gap broadens, joint filling is carried out using polyurea polymer material.
Need to check by four absolute altitudes in described construction technological process to ensure the flatness and level of ultra-flat terrace
Degree：
1. before pouring construction, absolute altitude is carried out to super flat die plate for the first time and checked；
2. after the completion of being flattened after pouring, second of absolute altitude to super flat die plate is checked；
3. in artificial leveling ruler of scraping after four roads strike off, for the third time check formwork elevation measuring；
4. in concrete surface polishing process, the 4th time formwork elevation measuring is checked.
Beneficial effects of the present invention：Formwork elevation measuring is under spirit level cooperation at construction joint of the present invention, and precisely convenient regulation is marked
Height, steel form is reinforced and fixed by Screw arbor with nut at both-ends, it is not necessary to welded, and is punched, and preferably, this method can prevent construction joint to globality
Locate the rupture of concrete corner angle and both sides sedimentation faulting of slab ends, reduce the damage caused on ground using equipment, reduce terrace maintenance and bring
High cost.
