BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view showing an embodiment of an attachment plate mounting bracket according to the present invention. First, an attachment plate mounting bracket according to the first embodiment of the present invention will be described. FIG. 1 is a front view of an attachment plate mounting bracket according to the first embodiment of the present invention,
FIG. 2 is a front view (a) and a side view (b) of a cylindrical body having a lid at one end of the attachment plate mounting bracket of FIG. 1, and FIG.
FIG. 4 is a front view (a) and a side view (b) of the rod-shaped body of the attachment plate mounting bracket of FIG. 1, and FIG. 4 is a front view (a) and a side view (b) of the tubular body having a lid at the other end. ) And FIG. 5 are views for explaining a method of manufacturing a cylindrical body having a lid at an end. Attached plate mounting bracket 1a according to the first embodiment of the present invention
As shown in FIGS. 1 to 4, a cylindrical body 2a having a lid at one end, a cylindrical body 2b having a lid at the other end, and a hole in the cylindrical body having these lids It is composed of a rod-shaped body 3 that enters inside.
It is for using two or more at a time.

The cylindrical body 2a having a lid at one end is
As shown in FIGS. 2 (a) and 2 (b), one end of the tube is provided with a lid 5a, and the entire hole 4a of the tube is covered with the lid 5a. Even if it covers the portion, any material may be used as long as the rod-like body 3 that enters the portion does not pass through. The lid 5a may be fixed by welding, screws, or the like, or may be manufactured by cutting a cylindrical body, or press-fit a hexahedron 8 at one end of the pipe as shown in FIG. May be fixed, and the press-fitted hexahedron 8
May be fixed to the pipe by welding.

A cylindrical body 2b having a lid at the other end.
Has a lid 5b provided so as to cover the other end of the hole 4b of the tube as shown in FIGS. 3 (a) and 3 (b). It may have the same shape as the cylindrical body 2a, or may have a different shape and dimensions such as different dimensions of each part, but may have the same shape or substantially the same shape as the cylindrical body 2a having a lid at one end. Dimensions are preferred because they are easier to manufacture. The cylindrical body 2b having the lid at the other end can be manufactured by a method similar to the method of manufacturing the cylindrical body 2a having the lid at the one end.

As shown in FIGS. 4 (a) and 4 (b), the rod-shaped body 3 of the attachment plate mounting bracket 1a according to the first embodiment of the present invention may have a columnar shape or an outer periphery. It may be a circular tubular body. The rod 3 has a hole 4 formed in a cylindrical body 2a having a lid at one end and a cylindrical body 2b having a lid at the other end.
It has an outer diameter smaller than the diameter of the smaller one of the holes a and 4b, preferably 1 mm or more. By reducing the diameter of the rod-shaped body 3 by 1 mm or more in this manner, even if the attachment plate 14 is fixed to the attachment plate mounting bracket 1a fixed to the beam 12 by welding, the attachment plate is 1 mm left and right.
This is because they can move.

The length of the rod 3 is 2 if the depth of the hole is longer than the depth of the hole of the cylindrical body having a smaller depth.
The cylindrical body 2a having two lids may be at least the total depth of the holes 4a and 4b of the cylindrical bodies 2a and 2b, but is preferably a cylindrical body 2a having two lids.
The total depth of the holes 4a and 4b of 2b is less than 90mm if the depth of each of the holes 4a and 4b is 45 mm, and the holes 4a and 4b of the cylindrical bodies 2a and 2b having two lids In the case where the depth is different (although it is actually different in all cases), the depth of the hole is longer than the depth of the hole of the cylindrical body by 20 mm or more. Even when the length of the rod-shaped 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 lids, the interval between the cylindrical bodies 2a and 2b having two lids is set. Longer lengths can be used, but they are too far apart and become unstable. On the other hand, if the rod 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 lids, as shown in FIG. This is because if used at an interval from the cylindrical body 2b having the above, at least the attachment plate can be moved up and down by the interval. In addition, rod-shaped body 3
The lower limit of the length can be used as long as it is longer than the depth of the hole of the cylindrical body having the shallower hole. However, the lower limit of the length is preferably at least 20 mm longer than the depth of the hole of the cylindrical body having the deeper hole. Even if the interval between the two cylindrical bodies 2a and 2b is about 5 mm, the cylindrical body 2a and 2b will enter about 15 mm into the shallower cylindrical body, so that it can be used stably as an attachment plate mounting bracket. . However, if the length is equal to or less than the total depth of the holes 4a, 4b of the cylindrical bodies 2a, 2b having two lids, it is preferable that the length is as long as possible, because it is more stable.

Next, an example of a method of using the attachment plate mounting bracket 1a will be described with reference to FIGS. 6 and 7. Referring to FIG.
The cylindrical body 2b having the lid of 1a and the mounting plate mounting metal fitting 1a used at the lower part are fixed to the web 13b of the beam 12 by welding, and the mounting metal fitting 1a used at the upper part is fixed to the web 13b of the beam 12.

The outer diameter of the tube and the diameter of the hole 7 may be substantially the same as or different from the outer diameter of the cylindrical bodies 2a and 2b having the lids at the ends and the diameter of the hole 7.

The shape of the rod 3 of the attachment plate mounting bracket 1b according to the second embodiment of the present invention is the same as that of the attachment plate mounting bracket according to the first embodiment. If the length is longer than the total depth of the depth of the hole of the cylindrical body having the shallower hole and the depth (length) of the hole 7 of the cylindrical body 6 without the lid, two pieces are required. It may be longer than the total depth of the holes 4a, 4b, 7 of the cylindrical bodies 2a, 2b having the lids and the cylindrical body 6 without the lid, but preferably the cylindrical bodies 2a, 2b having the two lids And the length of the holes 4a, 4b and 7 of the cylindrical body 6 without a lid, the length of which is smaller than the total depth of the cylindrical body having the lid with the deeper hole and the hole of the cylindrical body 6 without the lid. It is longer than the total length by 20 mm or more. The reason why the length of the rod-shaped body 3 is limited in this way is the same as that described for the attachment plate mounting bracket 1a of the second embodiment.

Next, an example of a method of using the attachment plate mounting bracket 1b will be described with reference to FIG. 10. Using two attachment plate mounting brackets 1b, one on the front and the other on the back, is used. The cylindrical body 2a, 2b having two lids of the contact plate mounting bracket 1b is
