-3.1. Fixing hanging bolts
(Use M10 hanging bolts. The bolts should be supplied in the field.)
(Give site of suspension strong structure.)
Hanging structure
• Ceiling: The ceiling structure varies from one building to one another. For de-
tailed information, consult your construction company.
1 Reinforcing the ceiling with additional members (edge beam, etc) must be re-
quired to keep the ceiling at level and to prevent the ceiling from vibrations.
2
Cut and remove the ceiling members.
3 Reinforce the ceiling members, and add other members for fixing the ceiling
boards.
For wooden construction
• Use the tie beam (for one story building) or second-floor beam (for two story
building) as strength members.
• To hang the air-conditioner, use a hard square timber of more than 6 cm if the
distance between beams is less than 90 cm and a hard square timber of more
than 9 cm if the distance between beams is less than 180 cm.
For reinforced concrete construction
• As shown in the figure below, fix the hanging bolts, or use square timbers to fix
the hanging bolts.
