Title:
BEAM STRUCTURE
Document Type and Number:
Japanese Patent JP2016191190
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve shear capacity.SOLUTION: In a man through-hole installation part 5 in a reinforced concrete beam part 3, a shaped steel 6 is embedded in such a manner that the material axis direction is directed toward the beam height direction. A pair of flange parts 8 of the shaped steel 6 is arranged in the extending direction of the beam part 3, a web part 9 of the shaped steel 6 has a man through-hole part 16 formed, preliminary main reinforcement bars 12 provided across the pair of flange parts 8 are arranged on both sides of upper and lower parts of the web part, and the preliminary main reinforcement bars 12 of the upper or lower part are bound to upper or lower main reinforcement bars 21 of the beam part 3 through preliminary shear reinforcement bars 23. The structure can be made simple by fitting both end parts of the preliminary main reinforcement bars 12 in penetration hole parts provided in the pair of flange parts 8. The shear capacity of the man through-hole 5 can be improved further by providing anchor parts 15 which extend laterally outward from the pair of flange parts 8.SELECTED DRAWING: Figure 3
