Hereinafter, a mounting jig according to an embodiment of the present invention will be described with reference to the drawings.
A mounting jig 1 shown in FIG. 1 has a hard resin or steel piece 3 having a cross section with legs 2 on both sides and having a substantially staple shape or a substantially inverted U-shape. 4 is protruded and fixed to both sides of the piece 3, and a bolt through hole 5 is formed in the center through the piece 3 and the mounting plate 4, and the mounting jig 1 is configured in the bolt through hole 5 together with the piece 3. A bolt 6 serving as a stopper is inserted from below (FIG. 2), and a nut 7 shown in FIG. 3 is screwed into the bolt 6 protruding from the mounting plate 4 so that the bolt 6 can be fixed.

  The lattice-like structure 9 shown in FIG. 3 has a structure in which vertical bars 9a and horizontal bars 9b are combined vertically and horizontally. For example, the lattice-like structure 9 is formed of a molded product made of FRP (a molded product other than FRP may be used). When the mounting jig 1 is assembled, the mounting jig 1 is inserted into the required opening 9c of the lattice structure 9 from the upper side of FIG.

  As shown in FIGS. 1, 1, and 2, the leg 2 is formed in a tapered shape, and the opening 9 c has a draft angle (when forming the lattice-like structure 9, the cross section gradually increases toward the upper end. The leg tip can be inserted into the upper end of the opening 9c.

  When the leg 2 is inserted from the tip of the leg into the opening 9c, the leg 2 eventually supports the crosspiece 9a or 9b that forms the opening 9c. However, when the leg 2 is further pushed in as it is, both legs 2 are pushed in while deforming inward. Then, the elastic force hits and fixes to the crosspiece 9a or 9b. The leg 2 is pushed in until the mounting plate 4 hits the edge of the opening 9c. When the mounting plate 4 protruding from the piece 3 hits the edge of the opening 9c, the mounting plate 4 acts as a stopper to prevent further pressing. .

  After the piece 3 is fixed to the opening 9c, as described above, the bolt 6 is passed through the bolt through hole 5 and fixed by screwing the nut 7 (FIG. 3).

  The attachment jig 1 of the embodiment shown in FIG. 1 is similar to the attachment jigs shown in the following embodiments in the openings 9c of the lattice-like structure 9 upside down from FIGS. It is also possible to install by pushing.

  The lattice-like structure 9 is used for a wall surface such as a partition, and when a member to be attached such as a book, a picture, a black (white) board, or an electric product is attached, the lattice-like structure 9 is attached to a required opening 9c of the leaning lattice-like structure 9 A mounting member (not shown) is removed from the bolt 6 protruding from the opening 9c of the mounting jig 1, and a member to be mounted is attached.

  When the lattice-like structure 9 is used for the passage and a member to be attached made of a display board displaying an arrow or the like is attached, the bolts of the attachment jig 1 attached to the required openings 9c of the lattice-like structure 9 arranged in the passage. The display board which is the said to-be-attached member is attached to 6. In this case, the bolt 6 is passed from above the display plate to the mounting plate 4 and the piece 3, and a nut is screwed and tightened in the piece. In this case, it is desirable to remove the mounting plate 4 and replace the display plate with the mounting plate 4.
