Shear reinforcement device for junctional region of column-slab

摘要

The present invention pillars which are mounted vertically on each of reinforcement slab reinforcement at the top and bottom side horizontally in areas that are joined to each other the pillars and slabs forming a reinforced concrete structure thereby increasing the resistance to shear-vertical locking type shear of slab joints It provides reinforcement. Such a pillar-vertical locking type shear reinforcement of the slab joint body is made up of configuration sub shaped to leave between the insertion space formed in the up and down direction in the central portion symmetrical to one another on both sides frame position of the slab reinforcement is cross-presented reinforcement each other by vertical descent to be installed in accordance with the upper jam easily fixed to the slab reinforcement, the other hand, improves the efficiency of the slab, reinforcing the construction of the shear reinforcement made simple and easy on the slab reinforcement. ; Column in accordance with the present invention shear reinforcement member 100, a vertical locking-type (100 ') of the slab joints are the first sub-frame 20, 20' and the second sub-frame 40, 40 'and, connecting piece It consists of 60, 60 '. The first sub-frame 20, 20 'slab reinforcement (3) in respect vertically arranged such that a predetermined length to form at which the first shear reinforcement for the bar (bar) (22) (22'), the first shear reinforcement for bar "and so the horizontal position on top of the first shear reinforcing bars 22 (22 for 22, 22, agent having a wide horizontal cross-sectional area than) 1, the upper head 24, 24 'and the first 'being presented horizontal position at the bottom of the first front reinforcement bars 22 (22 for the comprises a first lower head 26 (26') having a wide horizontal cross-sectional area than) shear reinforcing bars (22) 22 'for . The second sub-frame 40, 40 'the second front end reinforcement bars (42) (42 for being formed into a prescribed length so that it is placed perpendicular to the slab reinforcement (3) "bar for), a second shear reinforcement ( 42 and 42 the second upper head 44 ') being presented horizontally at the top of second shear reinforcing bars 42 (42 for the' having a wide horizontal cross-sectional area than) 44 'and the second for the shear reinforcement bar (42) (42 ') being presented horizontally at the bottom of the bar for the second shear reinforcement (42, 42' made of a second lower head 26 (26 ') having a wide horizontal cross-sectional area than), the 1 'is located spaced apart from the first sub-frame 20 (20 sub-frames 20, 20' so that the insertion space 30 is formed between a). Then, the coupling piece 60, 60 'are spaced apart from each other in the first sub-frame 20, 20' and the second sub-frame 40, 40 'both sides on both ends are fixed to the first sub-frame 20 20 'and the second sub-frame 40 (40' combine), and the first sub-frame 20, 20 'and the second sub-frame 40, 40' a between the insertion space 30 across the top so that the closure of the insertion space 30. The columns are configured as Vertical engaging type shear reinforcement member 100, 100 'of the slab junction By installation by vertical descent from the upper side of the post, the slab reinforcement (3) a construction the slab reinforcement (3) connecting piece (60) (60 ') characterized in that fixed to the rear so that the slab reinforcement (3) which passes through the insertion space 30. ; Pillars, slabs, slab reinforcement, shear reinforcement, shear reinforcement bars for the head
