Title:
FIXED STRUCTURE OF MAIN GIRDER AND PRECAST SLAB AND METHOD OF FIXING MAIN GIRDER AND PRECAST SLAB
Document Type and Number:
Japanese Patent JP2020100967
Kind Code:
A
Abstract:
To provide a fixed structure of a main girder and a precast slab with same number of protrusions capable of improving the strength against shear force.SOLUTION: A fixed structure 1A between a main girder 2 and a precast floor slab 3A, includes: the main girder 2; a protrusion 5A protruding upward on the main girder 2; the precast floor slab 3A having a housing 8 on the lower surface 6 for accommodating the protrusion 5A; and a filler 9 for filling the housing 8 accommodating the protrusion 5A. Since the protrusion 5A is formed of a tubular member in which one end of the opening 13 side is welded to the main girder 2, compared with the case where the protrusion 5A is a stud such as a steel rod, the welding length of the protrusion 5A to the main girder 2 with respect to the lateral projection area of the protrusion 5A can be increased. With this, the strength against the shear force of the fixed structure 1a including the main girder 2 and the precast floor slab 3A of the same number of protrusions 5A is improved.SELECTED DRAWING: Figure 3
