CEILING CONSTRUCTION WITH ACCESS DOOR

摘要

A ceiling construction for buildings comprises a plurality of flanged main beams (11) disposed in a predetermined spaced relationship to each other and bridging wall mouldings opposed and spaced to each other; a plurality of flanged cross beams (12) connected to the main beams (11) in a predetermined spaced relationship to each other at right angles to the main beams (11) so as to form a ceiling framework; a ceiling wall (13) mounted to the ceiling framework so as to form an access opening (21) in a predetermined position; a pair of auxiliary beams (14); a plurality of fastening means (15) for the auxiliary beams (14); an access door (16); and a plurality of mounting means (17) for the access door. The pair of auxiliary beams (14) each is bridged in a predetermined relationship flanges the opposite main beams (11) of the main beams 11 adjacent to and spaced to each other or flanges of the opposite cross beams (12) of the cross beams (12) adjacent to and spaced to each other in the access opening (21) on the ceiling wall (13). Further, the opposite ends of the auxiliary beams (14) are secured to one of the main and cross beams (11, 12) by the fastening means (15). Furthermore, the access door (16) is positioned in the access opening (21), and is secured to the ceiling framework by the use of the auxiliary beams (14) and mounting means (17).
