Description

  TECHNICAL FIELD The present invention relates to a fixture for fixing a base material for steadying that is used in the construction of a ceiling base, and in particular, between a plurality of suspension bolts suspended at a predetermined interval from a housing ceiling and a plurality of suspension bolts. The present invention relates to a fixing bracket used for fixing a steady rest base material to a suspension bolt when a ceiling foundation including a steady rest base material installed on a ceiling is installed.

  As a conventional ceiling structure, a conventional ceiling or a system ceiling is known (for example, see Patent Document 1). The conventional ceiling has a plurality of field receivers (channels) supported by the frame ceiling through suspension bolts, and a plurality of fields supported by the field receivers through joint members (W clips, S clips, etc.). It is composed of an edge (W bar, S bar, etc.) and a ceiling panel screwed to the field edge. Further, the system ceiling includes a plurality of field receivers supported by the frame ceiling part via suspension bolts, a plurality of T bars supported by the field receivers via joint members (such as T-bar hangers), and a lattice. It is comprised from the ceiling panel mounted on the T-bar assembled in the shape.

  By the way, in such a ceiling structure, in order to maintain the space | interval of a suspension bolt, it is preferable to construct the base material for steadying between several suspension bolts. In particular, in a ceiling base using a long suspension bolt, since the swing width of the suspension bolt is large, it is essential to prevent the suspension bolt from swinging with a base material for steadying. And as a base material for steadying, as shown in patent document 1, the thing of the beam type laid horizontally between several suspension bolts, or as shown in patent document 2, a plurality of suspension bolts A bracing type that is installed in a slanting manner in between is known.

In the construction of the ceiling foundation including the steady rest base material, a fixing bracket for fixing the steady rest base material to the suspension bolt is used. This fixing bracket is provided with a steady-state base material fixing portion fixed to a steady-state base material and a suspension bolt fixing portion fixed to a suspension bolt. Since the base material fixing part and the suspension bolt fixing part are made of different members, the number of parts required for fixing at one place increases, resulting in high costs. In addition, since a large number of fasteners (bolts, nuts, screws, etc.) are used for fixing one place, it takes a considerable amount of time to fix only one place, resulting in poor construction efficiency. In addition, the fixing bracket shown in Patent Document 2 is based on the premise that the base material for steadying is a long bolt material, and is applied when the base material for steadying is a U-shaped channel material in cross section. It was difficult.
