Topic There being a gadget for the former corner, in the column plate supporter the time tune doing, it was installed and because as for the standing up fixed part it is not concatenated, the screw it stopped the standing up fixed part in the beam and when it locks, the resistance flexural strength of the beam because becomes only tensile strength of the bend section, bent and vis-a-vis the standing up fixed part there was a possibility of displacing to the vertical when the power for direction and vertical direction operation problem was generated strength. Solutions The column plate the screw in the vertical it is the gadget for the corner which the time tune, it tries to do the aforementioned standing up fixed part, to extend the loop fixed part 24 which is piled up with other standing up fixed part 22 from shorter side side of the standing up fixed part 23 of aforementioned one to cover the opening of the corner section of the standing up fixed part with the said loop fixed part to form the respective standing up fixed part 22,23 of the perpendicular arm in the column plate supporter 21 of the triangular form which stops vis-a-vis the aforementioned column plate supporter.
