SUPPORTER FOR LOWER SECTION OF EXTERNAL CORRIDOR OF BUILDING

摘要

PURPOSE: To realize an external corridor or a balcony, which has no bearing column and is not included in a building area, by a method wherein an arm girder is installed at the upper end section of a body mounting lever and formed in an inverted L shape and using a supporter, to which an angle brace is installed extending over the intermediate section of the mounting lever and the intermediate section of the arm lever. ;CONSTITUTION: One side pieces of two angle materials 3 are disposed back to back, and the other side pieces are connected mutually by connecting plates 4. One side piece sections are formed in webs 1a, width size is broadened from lower sections to upper sections, edge sections are tapered, and slits 1c are formed. The other side piece sections are formed in flanges 1b. On the other hand, arm-lever connecting sections 5 are installed at the upper end sections of mounting levers 1, and affixed to the upper sections of the flanges 1b. The base end sections of arm levers 2 are set up to the plates 5b of the mounting levers 1. Angle braces 7 are fitted extending over the mounting levers 1 and the arm levers 2. Accordingly, this supporter is a body cantilever type and no bearing column is required, and a site can be utilized effectively.;COPYRIGHT: (C)1994,JPO
