Title:
METHOD OF MANUFACTURING MAIN GIRDER FOR FLOOR SLAB AND METHOD OF CONSTRUCTING FLOOR SLAB
Document Type and Number:
Japanese Patent JP2023110372
Kind Code:
A
Abstract:
To shorten an on-site construction period of a floor slab.SOLUTION: A main girder 2 has one side face 11 and the other side face 12 on both sides in a width direction, a recessed part for adhesion is provided on the one side face 11 of the adjacent one main girder 2, a release sheet 29 is provided on the other side face 12 of the adjacent other main girder 2 opposed to the one side face 11 provided with the recessed part for adhesion, and space-filling concrete is filled in a joint part 3 between the one side face 11 and the other side face 12 of the adjacent main girders 2, 2, since the adjacent main girders 2, 2 are separated by the release sheet 29 after the space-filling concrete is cured to form a space-filling concrete part 4 closely adhered to the recessed part 25 for adhesion, an interval of the joint part 3 is adjusted to place the space-filling concrete, since an outer surface 24 of the cured space-filling concrete part 4 has a shape formed by transferring the other side surface 12 of the adjacent main girder 2, it is possible to form a floor slab 1 with a prescribed dimension by lining it up at an installation site, thereby shortening an on-site construction period.SELECTED DRAWING: Figure 6
