<P>PROBLEM TO BE SOLVED: To provide a structure for shear reinforcement of joint hardware positions, etc. and at the same time for reinforcement of an opening, in order to solve a structural problem caused by the opening in a structure with the opening formed in the position where the joint hardware is provided. <P>SOLUTION: In a structure, in which joint hardware is used for reinforcing bars in the main structure parts of a structure such as a reinforced concrete or steel framed reinforced concrete structure and a position of the joint hardware is provided with an opening, integrated shear reinforcing bars made of bundled reinforcing bars mutually winding outermost reinforcing bars are disposed on the outward positions of both end parts of the joint hardware, an opening is provided in a plain space part surrounded by the joint hardware and the integrated shear reinforcing bars, and strengthening steel bars having diagonal members or curved members and straight members continued thereto are provided in a remaining space part around the opening so as to surround the opening. The strengthening steel bars are disposed in the position inside of the integrated shear reinforcing bars overlapping the strengthening steel bars, and some of the strengthening steel bars are connected with the integrated shear reinforcing bars or with the shear reinforcing bars, main reinforcing bars, and core steel bars in addition to the integrated shear reinforcing bars to constitute the reinforcement of the opening. <P>COPYRIGHT: (C)2012,JPO&INPIT |
