Precautions for fire rolling shutter door
The style of fireproof rolling shutter door and matters needing attention in measurement design. The fireproof rolling shutter door is widely used in commercial buildings, factory buildings and underground garages. The specific installation standards and specific reputation are as follows: measurement design: step one: general classification of rolling shutter installation. Self inspection of fire shutter: manual operation mode: whether a circular iron chain set in the storage box at one side of the shutter can be found to operate the lowering and rolling.. When the installation form is wall side installation: when there are embedded parts (steel plates) in the building, after cleaning the installation datum plane, check and verify whether the size and external position of the embedded parts are suitable for the installation drawing design. If the design requirements are appropriate, this is the datum plane for the installation of large and small supports. The facing bricks around the wall projections shall be cut and matched with the whole brick, and the edges shall be clean. (Check the date of delivery and the date of maintenance; carbon dioxide, dry powder and clean gas extinguishers are outdated if they have been delivered for 5 years or maintained for 2 years; foam extinguishers are outdated if they have been delivered for 3 years or maintained for 1 year, and they need to be sent to the fire extinguisher factory or professional maintenance unit for maintenance).
After the Henan fireproof rolling shutter door is installed, the ceiling shall be installed, and the edge of the ceiling shall be 50mm away from the shutter to avoid friction; c. The foundation dimensions of rolling shutter doors and parts shall be measured, which shall be consistent with the requirements of the design institute.
Requirements and area calculation for fireproof Henan fireproof rolling shutter door Requirements for fireproof Henan fireproof rolling shutter door: prepare for curtain surface installation, open the roll and check whether the curtain surface (steel, inorganic cloth) is deformed or damaged due to storage, transportation and other factors. Drill expansion bolt holes with impact drill, and the requirements for upper expansion bolt are the same as before. Solid wood composite floor surface shall be free of warpage. Determine the center height of the auxiliary shaft at one end of the gate post, and set out the cross line of the bearing plate adjacent to the bolt hole. With this as the benchmark, the rigid horizontal tube finds out the center position of the auxiliary shaft at the other end of the gate post, and sets out the cross line of the bearing plate screw hole. f. After the guide rail is installed, the clear width of the hole shall be ensured. The sealing strip of plastic door and window sash shall not be out of groove. c? The guide rail shall be installed stably on site, and the adjacent distance between the embedded steel parts and the guide rail shall not be greater than 600mm. 2. Site acceptance record and re inspection statement.
