Description

  The present invention relates to a cross connector for connecting a plurality of rod-shaped bodies that cross each other.

  For example, suspension equipment such as cable racks, ducts, lighting equipment, and indoor units of air conditioning equipment may be suspended from structures such as ceiling slabs using rod-like bodies such as suspension bolts. In such a case, in order to suppress the swinging movement of the suspended equipment caused by an earthquake or the like, another rod-shaped body is arranged in a crossing posture with respect to the suspended rod-shaped body, and these are mutually connected to be reinforced. There is a case. For this purpose, a cross connector that connects three or more rod-like bodies in a crossed state may be used. An example of the above-described cross connector is disclosed in, for example, a catalog “Negros Electric Works Co., Ltd.,“ New Release Gatchly Lock Suspension Bolt Stabilizer / Fully Screw Cross Metal ”(Non-Patent Document 1).

  Hereinafter, the cross connector of Non-Patent Document 1 is shown in FIG. 10 of the present application and will be described with reference to FIG. The cross connector 100 of Non-Patent Document 1 includes a T-shaped narrowing member 110 for tightly attaching a suspension bolt 140 and three swing members 120 connected to the narrowing member 110 using bolts and nuts. The swing member 120 is bent and formed in an L shape having a support piece 121 and a mounting piece 122. The three brace bolts 150 that intersect the suspension bolt 140 are fastened from both sides using a pair of nuts while being inserted into the insertion holes of the mounting piece 122, and are fixed to the swing member 120.

  In the cross connector 100 of Non-Patent Document 1, nut tightening operations are required at a total of six locations, and two nut tightening operations per one are required to fix the brace bolt 150. For this reason, much labor is required to connect one suspension bolt 140 and three brace bolts 150. Further, in order to fix the brace bolt 150 to the attachment piece 122, it is necessary to insert the brace bolt 150 through the insertion hole of the attachment piece 122. For example, when the brace bolt 150 is long, such insertion operation is not easy. There may be no. Therefore, also from this point, much labor is required to connect the suspension bolt 140 and the brace bolt 150.
