Hereinafter, an attachment plate mounting structure according to an embodiment of the present invention will be described with reference to the accompanying drawings.
The attachment plate mounting bracket 1 used in the attachment plate attachment structure according to the embodiment of the present invention includes a first cylindrical body 2a having a stopper 5a at one end as shown in FIG. When the end plate has a second cylindrical body 2b having a stopper 5b and a rod-shaped body 3 that enters into the hole of the cylindrical body having these stoppers, the attachment plate is large and heavy. For use two or more at a time.

  The first cylindrical body 2a having a stopper at one end thereof has a shape in which a stopper 5a is provided at one end of a tube as shown in FIG. 2, and the stopper 5a is made of a cylindrical material. A portion having a predetermined width in the circumferential direction of the end portion and a predetermined length in the length direction is bent inward, and a plurality of, for example, 2 to 4 stoppers are provided at the end of the cylindrical body 2a (see FIG. 2, FIG. 3, FIG. 4 and FIG. 5).

  The stopper is formed by providing two pairs of cuts extending a predetermined length in the length direction of the tubular material, and bending a tongue piece between the two cuts inward. It is preferable that the cutting and bending when forming the tongue piece are performed simultaneously. This is possible by providing two cutters in the press.

  Further, the second cylindrical body 2b having the stopper 5b at the other end is formed by caulking a circular stopper 5b at the other end of the tube hole 4b as shown in FIG. The stopper 5b of the cylindrical body 2b may have another shape / form. In short, any shape and form may be used as long as the first stopper 5a can be distinguished from a distance.

  The rod-like body 3 of the attachment plate mounting bracket 1a shown in FIG. 1 may be cylindrical or a tubular body having a circular outer periphery. This rod-shaped body 3 has an outer diameter smaller than the diameter of the smaller one of the holes 4a and 4b of the cylindrical body 2a having a stopper at one end and the cylindrical body 2b having a stopper at the other end, Preferably, it has an outer diameter smaller than 1 mm. Thus, by reducing the diameter of the rod-shaped body 3 by 1 mm or more, even if the attachment plate 14 is fixed by welding to the attachment plate mounting bracket 1 a fixed to the beam 12 by welding, the attachment plate is left and right by 1 mm or more. It is because it can move.

  Moreover, if the length of this rod-shaped body 3 is longer than the depth of the hole of the cylindrical body with the shallower depth, the length of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers is reduced. The total depth may be greater than or equal to, but preferably less than or equal to the total depth of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers, for example, 90 mm if the depths of the holes 4a and 4b are both 45 mm. In the following, when the depths of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers are different (actually different in all cases), the depth of the holes is deep. It is longer than the depth of the hole of the cylindrical body by 20 mm or more. Even if the length of the rod-like body 3 is equal to or greater than the total depth of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers, the interval between the cylindrical bodies 2a and 2b having two stoppers is reduced. If it is long, it can be used, but it becomes unstable because the interval is too wide. On the other hand, if the rod-shaped body 3 has a length equal to or less than the total depth of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers, the cylindrical body 2a and the stopper having stoppers as shown in FIG. This is because at least the attachment plate can be moved up and down by an amount spaced apart from the cylindrical body 2b having a gap. Further, the lower limit of the length of the rod-shaped body 3 can be used if it is longer than the depth of the hole in the cylindrical body with the shallower hole, but 20 mm or more than the depth of the hole in the cylindrical body with the deeper hole. If the distance between the two cylindrical bodies 2a and 2b is increased by about 5mm, the longer one will be inserted into the cylindrical body with the shallower hole about 15mm. Because you can. However, if the length is equal to or less than the total depth of the holes 4a and 4b of the cylindrical bodies 2a and 2b having two stoppers, the longer one is preferable because it is stable.

  Next, the attachment plate mounting structure according to the embodiment of the present invention using the above-mentioned attachment plate mounting bracket 1 will be described with reference to FIGS. 7 and 8. The cylindrical body 2a having the stopper 5a is disposed on the upper side of the attachment plate mounting bracket 1a used for the upper portion and on the lower side of the attachment plate mounting bracket 1b used for the lower portion. At this time, the stopper 5a is disposed so as to be positioned on the upper side in the cylindrical body 2a of the attachment plate mounting bracket 1a used in the upper portion and on the lower side in the cylindrical body 2a of the attachment plate mounting bracket 1b used in the lower portion. Is done. The cylindrical body 2b having the stopper 5b is disposed on the lower side in the attachment plate mounting bracket 1a used in the upper portion and on the upper side in the attachment plate mounting bracket 1b used in the lower portion.

This is because omissions will occur. In this sense, the upper cylindrical body 2a of the upper attachment plate mounting bracket 1a and the lower cylindrical body 2a of the lower attachment plate mounting bracket 1b may be fixed to the web 13b of the beam 12. Further, the contact plate 14 a is fixed to the web 13 b of the beam 12 with one or two temporary bolts. After the steel column 10 (see FIG. 9 and the like) is erected and before the beam 12 is abutted against the bracket 11 (see FIG. 9 and the like) of the steel column 10, the temporary bolt is removed, and the attachment plate 14a is shown by a two-dot chain line in FIG. Expand as shown. After that, when the bracket 11 and the beam 12 are brought into contact with each other, the attachment plate 14a is closed, the hole is aligned, and fixed with a bolt. The same applies to the back side.

  A cylindrical body (not shown) without a stopper is interposed between a cylindrical body 2a having a stopper 5a at one end and a cylindrical body 2b having a stopper 5b at the other end. It can be used with the plate mounting bracket lengthened.

  A cylindrical body without a stopper is simply a tube with a hole. The outer diameter of the tube and the diameter of the hole may be substantially the same as or different from the outer diameter and the hole diameter of the cylindrical bodies 2a and 2b each having a stopper at the end.

  In the attachment plate mounting structure of the present invention, for example, two attachment plate mounting brackets on the upper and lower sides are used, and two types of cylindrical bodies are used. Since the cylindrical body is welded to the same member (web, attachment plate), it can be accurately welded and the above-mentioned artificial welding mistakes can be prevented.

  In the above description, the cylindrical bodies 2a and 2b can be confirmed based on the shape of the stopper. However, the above determination may be made based on a difference in color or the like. Moreover, you may combine these.
