FLOOR STRUCTURE AND WOODEN FLOOR BOARD IN BUILDING CONSTRUCTED BY STEEL FRAMEWORK

摘要

PROBLEM TO BE SOLVED: To shorten the execution period of construction work by the method wherein square woods are connected to each other through fitting of a tongue and a recessed groove, arranged in a collected manner, and tightened by passing through connection bolts, and formed in a board. ;SOLUTION: Square woods 1 are connected to each other by fitting a tongue 10 to a recessed groove 11, arranged in parallel, connection bolts 2 are inserted in bolt insertion holes 12, and tightened by washer plates and nuts so as to be connected in a floor board. A floor board A to be assembled is loaded on beams 5, 5 of steel framework, screws are driven from the beam 5 so as to be directly connected to the beam 5, or a bracket is abutted on the beam 5, the bracket is tightened to the floor board A by screws, and connected integratedly with the beams 5, 5 for assembly. The execution to the steel framework is only to stretch and connect the pre-fabricated wooden floor board to the beam, and the execution period of a floor structure can be shortened.;COPYRIGHT: (C)1998,JPO
