Description

  The present invention relates to a construction support technique for screwing a mounting portion of a mounting member made of a magnetic material on a mounting target side surface of a mounting portion such as a stud.

  An example of a mounting material made of a lightweight material steel pillar, which is an example of a mounted part, is an example of a magnetic material mounting material for a metal partition that supports equipment such as a wiring box placed inside a wall. A fixing bracket is attached. For example, as shown in Patent Document 1, this fixing bracket is formed by bending a plate-like support portion that supports equipment and a plate-like attachment portion that is screwed to a side surface to which a stud is attached into an L shape. Configured. Further, an attachment hole into which a tapping screw, which is an example of an attachment screw, is inserted is formed through the attachment portion.

  When attaching the fixing bracket to the stud, the mounting position of the fixing bracket is marked on the mounting target side surface of the stud, and the fixing bracket mounting portion is applied to this marking position. In this state, the tapping screw arranged in the mounting hole of the mounting portion is screwed with a tool such as an impact screwdriver, and the mounting portion of the fixing bracket is fastened and fixed to the side surface of the stud to be mounted.

Japanese Patent Laying-Open No. 2015-023626 JP 2008-005687 A

  In the fixing metal fitting shown in Patent Literature 1, when the tapping screw is screwed, the support portion of the fixing metal fitting is gripped with one hand and the attachment portion is pressed against the attachment target side surface of the stud from the vertical direction. However, since the position holding force is weak and unstable only by pressing from the vertical direction, when the tool is operated with the other hand and the tapping screw is screwed in, the tapping screw abutting against the lightweight steel stud is not used. Due to the movement, the mounting portion is easily misaligned, and each time it is necessary to reposition the mounting portion to the marking position on the side surface to be mounted, which is inconvenient for screwing the mounting portion.

  In the fixing metal fitting shown in Patent Document 2, the mounting portion and the projecting portion are in contact with the mounting target side surface and the adjacent side surface orthogonal to each other, so that the holding portion holds the mounting portion at the marking position on the mounting target side surface of the stud. Will improve. On the other hand, it is necessary to bend and form the protruding portion at the mounting portion of the fixing bracket, which increases the cost of the fixing bracket. In addition, the adjacent side surface that is orthogonal to the side surface to which the stud is attached is a mounting surface for the wall material such as gypsum board. It is necessary to bend it to the opposite side position that does not become or to cut and separate the protruding part. Therefore, there is an inconvenience that it takes time to process the protruding portion after the fixing bracket is screwed.

  In view of this situation, the main problem of the present invention is to provide a fixing aid that can efficiently and easily attach the attachment portion of the attachment material to the attachment target side surface of the attachment portion while avoiding an increase in the cost of the attachment material itself. There is in point to do.
