This paper introduces the key points of aluminum alloy formwork construction technology, including formwork connection, adjustable vertical pole, early dismantling system, diagonal bracing, external wall Rachel, wire box, conduit fixing and positioning, formwork dropping, stair formwork, reserved transfer holes, release agent and aluminum alloy formwork transportation.

Easy to assemble

Simple tools, easy assembly, convenient operation, low technical requirements and tight splicing to avoid slurry leakage and dislocation.

Adjustable column

The adjusting part is in the middle of the vertical rod, which is convenient to operate and can be roughly adjusted and finely adjusted.

Early dismantling system

The aluminum alloy template can be disassembled first, which improves the turnover rate of the template.

diagonal brace

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

External wall Rachel

The combination of top and pull can be realized by knotting the hanging chain, which can effectively control the verticality and flatness of the wall column, and the operation is simple and convenient for workers.

Fixation and positioning of box and catheter

The wire box is fixed with an expansion cap, and the water pipe hole is fixed with screws, which is convenient to disassemble. When the box body and the catheter are positioned accurately for the first time, the upper positioning can be consistent.

Delete template

The opening and closing die is connected by bolts, which is convenient for demoulding and has a good effect on reducing the damage of the external angle at the falling plate.

Stair formwork

All of them are closed by aluminum alloy formwork, and the observation port is reserved at the bottom to ensure the integrity and size of the stairs, and the visual effect is very good.

Reserved transmission hole

It is mainly used for material transfer, and the hole edge is inclined to facilitate subsequent plugging.

demould

Reduce mold sticking and use vegetable oil as release agent to ensure the visual quality of concrete surface.

Transportation of aluminum alloy formwork

After the tower crane is used for the first time, it is transported manually. The maximum size of the formwork is 0.4×2.7m, and its weight is less than 20kg.
