<p><P>PROBLEM TO BE SOLVED: To provide a joint method capable of safe construction without requiring time and labor of construction compared to a conventional bracket joint method, regarding a bracket joint method of columns/beams in a prestressed concrete structure. <P>SOLUTION: In the bracket joint method of columns/beams, a bracket 1 for disposing a beam between columns is formed by integrating both upper and lower leg parts 1a and 1b inserted and fixed to fixing holes perforated on sidewalls of the columns, a receiving part 1c, a support part 1d and a reinforcing filler 4 filled in a space part with a column sidewall surface on the inner side of the bracket. After the bracket is fixed by inserting the leg parts of the bracket to the fixing holes of columns 2, a beam 5 is disposed between the columns 2 and 2 that the bracket 1 is made to face, non-shrinkage mortar 6 is filled in a joint part 5a for fitting the bracket of the beam. Thereafter, prestress is introduced to the beam 5 between the columns 2 and 2 by tension of a tension member 7. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
