CEILING CONSTRUCTION WITH ACCESS DOOR

摘要

A ceiling construction for buildings has a plurality of flanged main beams disposed in a predetermined spaced relationship to each other and bridging wall mouldings opposed and spaced from each other; a plurality of flanged cross beams connected to the main beams in a predetermined spaced relationship to each other at right angles on the main beams so as to form a ceiling framework; a ceiling wall mounted to the ceiling framework so as to form an access opening in a predetermined position; a pair of auxiliary beams; an access door; and a plurality of mounting devices for the access door. The pair of auxiliary beams each is bridged in a predetermined relationship to the opposite main beams of the main beams adjacent to and spaced from each other or the opposite cross beams of the cross beams adjacent to and spaced from each other on the inner side of the ceiling wall in relation to the access opening. Further, the access door is positioned in the access opening, and is secured to the ceiling framework by the use of the auxiliary beams and mounting devices.
