发明名称 INSTALLATION STRUCTURE OF COLUMN BASE, AND ERECTING METHOD THEREFOR
摘要 <p>PURPOSE:To simply and firmly install a column base for a handrail by a method wherein a stand for the column base and a pressing plate are fastened together after the pressing plate attached to the lower end of the column base is engaged with the peripheral edge of an installation hole. CONSTITUTION:A plurality of installation holes 3 in polygonal shape or in shape of imperfect circle are formed to specified positions over a structure like a floor or a rooftop made of ALC board 2. A column base 4 for a handrail to which a pressing plate 5 approximately the same in the shape as the hole 3 and capable of being inserted is attached to its lower end is inserted into the installation hole 3. Then, the pressing plate 5 is turned so that its long side becomes in parallel with the short side of the installation hole 3, and thereby the pressing plate 5 is engaged with the peripheral edge of the installation hole 3 provided to the underside of the structure. After openings occurring to a place between the pressing plate 5 and the installation hole 3 are covered with mortar-receiving plates 8 and 8, the column base stand 9 and the pressing plate 5 are fastened together with bolts 6 and nuts 7, 13, 14. Then, mortar is poured into the installation hole 3 through an opening 9A of the column base stand 9.</p>
