Description

  The present invention relates to a fitting combination type structural member.

  Conventionally, structural members such as wiring racks have secured dimensional accuracy because the main members on both the left and right sides and the joining auxiliary member (cross member) are joined between the left and right main members and the main members by welding. Special jigs and dedicated welding technicians were necessary to improve work efficiency.

  Of course, if welding is performed, distortion and spatter are generated by welding, so the process of strain relief and repair work is indispensable, which is one of the causes of cost increase.

  Accordingly, there is a demand for early development of a structural member that can be easily assembled by anyone and that can ensure dimensional accuracy and improve work efficiency.

The patent documents of structural members and joining members that have been filed so far are introduced for reference. (See Patent Documents 1 to 3.)

  As means for solving this problem, a pair of main members provided symmetrically opposite to each other, a plurality of auxiliary joining members provided between the main members and the main members and joined, and the joint portions are fixed and dropped off. The main member is formed of a plurality of locking members such as rivets, and the main member includes a rectangular locking hole that fits the convex locking portion of the joining auxiliary member on the lower surface, and a rivet or the like on the side surface. The fixing member mounting holes are provided at predetermined intervals, and the joining auxiliary member includes a convex locking portion that fits the locking holes of the main member at the left and right lower portions at both ends, and a rivet or the like at both side surface portions. Each of the locking member mounting holes is provided, and when the main member and the joining auxiliary member are joined, the convex locking portion of the joining auxiliary member is fitted into the locking hole portion of the main member, and the main member is joined. Rivet etc. in each mounting hole provided in the side part of the member and joining auxiliary member In which is fitted a locking member fixed to caulking.

  As an effect of this device, a pair of main members provided symmetrically opposite to each other, a plurality of joining auxiliary members that are provided and joined between the main members and the main members, and a plurality of members that are secured to the joints to prevent dropping. The main member includes a rectangular locking hole that fits the convex locking portion of the joining auxiliary member on the lower surface portion, and a locking member such as a rivet on the side surface portion. Mounting holes are provided at predetermined intervals, and the joining auxiliary member is provided with a convex locking portion adapted to the locking holes of the main member at the left and right lower portions of both ends, and mounting of locking members such as rivets on both side surfaces. When the main member and the auxiliary joining member are joined, the convex engaging portion of the auxiliary joining member is fitted into the engaging hole portion of the main member, and the main member and the auxiliary joining member are provided. A locking member such as a rivet is attached to each mounting hole provided on the side surface of the member. By staking and fixing, the processing time is reduced, the dimensional accuracy is improved, and the welding process is eliminated, so that welding jigs and welding technicians are unnecessary, and welding spatter and distortion are eliminated. The beauty of the appearance can be improved by elimination, and there are extremely beneficial effects such as improvement of quality and improvement of workability, productivity, safety and economy.
