Description

  The present invention relates to a bolt connector that connects three bolts.

  For example, an indoor unit of an air conditioner, a lighting apparatus, a hanging device such as a cable rack may be hung from a structure such as a ceiling slab using a hanging bolt. In such a case, in order to suppress the swinging movement of the lifting equipment caused by an earthquake etc., a suspension bolt is disposed in a cross posture with respect to other lifting bolts located on both sides from the lifting bolts, They may be mutually connected and reinforced. In this case, a bolt connector is used to connect the suspension bolt and the two anti-vibration bolts.

  An example of such a bolt connection is disclosed, for example, in Japanese Patent No. 6069453 (Patent Document 1). The bolt connector of Patent Document 1 comprises a base member [narrowing body 1], two narrowing members [diagonal support 3], and two connecting bolts [n for fixing the narrowing member to the base member] And a connecting bolt 2]. Then, by overlapping the narrowing attachment member and the base member and connecting them with the connection bolt, the angle of the anti-vibration bolt [long bolt Q] can be adjusted centering around the connection bolt, and the anti-vibration bolt is narrowly attached. It is crimped and fixed to the base member by a member. By this, Patent Document 1 states that the swing bolt of the suspension bolt can be easily fixed.

  However, in the bolt connector of Patent Document 1, the base member is composed of two members, the first base member [outside narrow attachment 1A] and the second base member [inward narrow attachment 1B], and these are suspension bolts It is fastened and integrated by two connecting bolts on both sides. In order to attach the bolt connector having such a configuration to the suspension bolt, after the suspension bolt is sandwiched between the first base member and the second base member temporarily assembled by one connection bolt (see FIG. 8 of Patent Document 1) (B)) Attach the second connecting bolt anew (the same figure (b)). Thereafter, a second narrowing member is newly attached to the connection bolt, and then the connection bolt is tightened (the same figure (c)).

  As described above, in the bolt connector of Patent Document 1, the suspension is performed in a state in which at least one of the two connection bolts that integrate the first base member and the second base member that constitute the base member is removed. It is necessary to do the installation work to the bolt. Naturally, it is necessary to work with at least one of the two narrowing members also removed. For this reason, it is necessary to handle a plurality of independent members at the same time, which may take time in the mounting operation. In addition, when such mounting work is performed at a high place, there is also a possibility of danger.
