1. formwork connection: simple tools, easy assembly, convenient operation, low technical requirements and tight splicing to avoid slurry leakage and dislocation.

2. adjustable upright post: the adjustment position is in the middle of the upright post, which is convenient for operation and can be used for coarse adjustment and fine adjustment.

3. Early dismantling system: aluminum alloy formwork can be dismantled first, which improves the turnover rate of formwork.

4. diagonal bracing: diagonal bracing can effectively prevent the wall column from shifting during the pouring process, and it is stable and convenient to fix it on the floor with expansion bolts. The screw device in the middle can effectively adjust the verticality of the wall column.

5. Rachel of external wall: Rachel with hoist chain to realize the combination of top and pull, which can effectively control the verticality and flatness of wall column, and the operation is simple and convenient for workers.

6. Fixation and positioning of box and conduit: the box is fixed with expansion cap, and the hole of water pipe is fixed with screw, which is convenient for removal. When the box and conduit are positioned accurately for the first time, the upper positioning can be consistent.

7. Deck-down formwork: the retractable formwork is linked by bolts, which is convenient to dismantle the formwork and has a good effect on reducing the damage of the external angle at the board-down.

8. Stair formwork: All of them are sealed with aluminum alloy formwork, and observation port is reserved at the bottom to ensure the integrity and size of the stairs are consistent, and the visual effect is very good.

9. reserved transfer hole: it is mainly used for material transfer, and the hole edge is inclined with a large top and a small bottom to facilitate subsequent plugging.

1. release agent: reduce mold sticking, and use vegetable oil as release agent to ensure the visual quality of concrete surface.

Second, special precautions on site

1. The formwork of elevator shaft, stairwell and outer fence column shall not be less than 2mm； into the lower structure; The root of wall column formwork should be sealed tightly to avoid slurry leakage and root rot; After the installation of reinforcement, the sundries in the formwork should be cleaned up.

2. When shuttering, the aluminum alloy formwork (including anti-formwork) must be cleaned, and the water-based release agent should be fully brushed. It is forbidden to use other compounds instead of release agent, so as not to cause concrete surface pollution and mold sticking.

3. The aluminum alloy formwork must be shuttered according to the number, and the redundant screw holes of the formwork should be blocked with special covers or repaired by the manufacturer to avoid slurry leakage from affecting the impression.

4, doors and windows (including windowsill) tongue-and-groove, wall column plastering strip should be retained correctly.

the hanging plate at the floor position between meters in buildings 5, 3#, 5#, 7# and 8# should be changed according to the serial number: 216DPXSJ32, and the position of constructional column there should be retained.

6, when concrete pouring, must appoint someone to look at the mold (bricklayer's team should send a full-time cleaning), found that the mold running, displacement timely processing, to ensure the engineering quality, such as mold running and slurry leakage, timely clean up the concrete to the operational layer, to avoid material waste.

7. The matters of floor formwork elevation shall be carried out according to the technical disclosure of floor elevation control.

8. Do three inspections: self-inspection, mutual inspection and handover inspection! Team self-inspection, mutual inspection: after the aluminum alloy formwork is reinforced and corrected, self-inspection shall be conducted to check whether the bolt pin (spacing @3mm) and wedge are missing, whether the spacing meets the requirements and whether they are fastened. The verticality of the wall column, flatness of the roof, cross-sectional size, etc. shall be mainly checked. After the self-inspection is completed, it shall be reported to the building number chief and the quality inspector, and the next working procedure can be carried out only after the quality inspector has accepted and applied for inspection.
