PROBLEM TO BE SOLVED: To overcome problems of a form for a floor opening of a reinforced concrete building, wherein, though the concrete around the form is disassembled after being solidified, since the upper part of the form is made slightly larger than the lower part to facilitate disassembly, namely, a draft is provided thereto, the shaft of an anchor using a long nut attached at right angle to the side plate of the form is buried while being tilted by the same angle as the draft of the side plate, and therefore, several tens of deformed reinforcements screwed with the anchor later are also tilted temporarily, and much labor and time are required for correcting these reinforcements horizontally.SOLUTION: The four corners of the form are held with a pair of brackets made of a steel angle and fixed, while the side plate of the form at the floor opening is vertically installed. However, since the brackets have a structure as shown in Figs. 2 and 3, the brackets can be easily disassembled and removed from a solidified slab irrespective of the fact that the side plate is installed vertically. Then, the deformed reinforcements screwed with the anchor are stored horizontally, and can be welded without bending the deformed reinforcements brought into contact with these deformed reinforcements so as to face each other. |
