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 a risk that part of the parts may fall.

The curved portion 42) is locked only at one side in the extending direction of the base member 3. In the present embodiment, the extension direction of the base member 3 is a direction from the first attachment portion 31 of the first base member 30 toward the second attachment portion 32 via the corner portion.

  In this temporary assembled state, for example, the first attachment portion 31 of the first base member 30 and the bending portion 44 of the second base member 40 are pinched to compresses and deform the elastic member 9 on the first connection bolt 7 side. Thus, the first base member 30 and the second base member 40 are expanded (see FIG. 8). Then, the suspension bolt P is slid between the first base member 30 and the second base member 40 in a radial direction and inserted through the gap G generated thereby (* actually, the bolt connector 1 side is Move and move relative as above). Thereafter, when the external pressure on the elastic member 9 is released, the elastic member 9 presses the first base member 30 against the second base member 40, and the base member 3 is temporarily fixed to the suspension bolt P.

To conclude. Further, the angle adjustment of the second narrowing member 6 and the second stop bolt Q 2 is performed, and the second stop bolt Q 2 is locked to the locking notch portion 64 of the second narrowing member 6. To conclude. Since the two anti-vibration bolts Q are tightly fixed between the base member 3 and the corresponding narrowing members 5, 6 by the fastening of the corresponding connection bolts 7, 8, the three bolts crossing each other are mutually connected. Can be easily connected.

  Further, in the state where all the parts constituting the bolt connector 1 are temporarily assembled, the mounting operation can be performed while handling them collectively, so that the mounting operation can be easily performed. Especially at high places, the mounting work can be performed safely.
