Description

  The present invention was devised to eliminate the above-mentioned problems, and the field edge is inserted into the inverted U-shaped groove through a field edge fixing bracket fixed to the field edge receiver on the ceiling base. The field edge of the field edge support receiving part is supported by the field edge support receiving part inserted in In addition to receiving the vibration load on the reverse U-shaped groove, the vibration in the lower direction (the direction away from the reverse U-shaped groove on the field edge) is regulated, and rattling between the field edge and the field edge receiver An object of the present invention is to provide an anti-seismic reinforcement member for a field edge fixing bracket that can prevent misalignment of the edge edge fixing bracket and the like.

  The present invention is configured as described above, so that the field edge is supported by the field edge support receiving part inserted into the inverted U-shaped groove via the field edge fixing bracket fixed to the field edge receiver. However, since the field edge support receiving part can be attached in a state where the upper surface piece of the field edge fitted part is brought into contact with the field edge receiving mounting part and is firmly covered by the tilt regulating part, When the field edge support receiving part receives vibration in the vertical direction due to an earthquake or the like, the rising upper end part of the field edge support receiving part concentrates on the inverted U-shaped groove on the field edge and is in upper dynamic pressure contact Such a vibration load can be received and distributed by the field edge fitting part, and can not only prevent the deformation of the inverted U-shaped groove and the expansion of the field edge, but also the inverted U-shaped groove of the field edge. Vibrations in the downward direction that are separated from the It is possible to prevent the occurrence of rattling between the field edge and the field edge receiver and the positional displacement of the field edge fixing bracket, etc., and the reinforcement work to improve the seismic strength against the field edge fixing bracket can be easily performed. At the same time, the upper end of both sides of the field edge support receiving part can be permanently kept in a good state where it is in close contact with the inverted U-shaped groove, contributing to the maintenance of structural quality characteristics by improving the earthquake resistance of the entire ceiling substrate can do. In addition, since both ends of the field edge fitting portion are screw-fixed at both side surface portions of the field edge which is the lower surface area of the field edge support receiving portion, the fixed screw itself together with the tilt regulating portion is an inverted U-shaped groove on the field edge. It is possible to contribute to the regulation of the downward movement of the field edge support receiving portion in the portion, and it is possible to prevent the occurrence of further backlash and displacement.
