Construction process of aluminum plastic plate door head

The construction process of aluminum plastic plate door head is as follows:

1. According to the axis and elevation line on the main structure, the installation position line of the support skeleton shall be accurately snapped onto the main structure according to the design requirements.

2. Weld and fix the connector with the embedded parts on the main structure. When there are no embedded iron parts on the main structure, holes can be drilled on the main structure and expansion bolts can be installed to fix the connecting iron parts.

3. Fix the antirust treated column on the connector with welding or bolts accurately according to the snap line position.

4. Install fireproof materials and use high-quality fireproof cotton. The fire resistance period shall meet the requirements of relevant departments. Fix the fireproof cotton with galvanized steel plate. The fireproof cotton shall be continuously sealed on the space between the floor slab and the metal plate to form a fireproof belt, and there shall be no gap in the middle.

5. Install the aluminum plate, and fix the aluminum alloy plate finish on the section steel frame one by one with rivets or bolts according to the construction drawing. A joint of 10 ~ 15mm shall be reserved between plates to adjust the installation error.

6. Deal with the plate joint. After cleaning the metal plate and frame surface with detergent, immediately place a sealing strip or weatherproof adhesive strip in the gap between aluminum plates, and then inject silicone weather resistant sealant and other materials. The glue injection shall be full without gap or bubble.
