はなお改善の余地がある。(Problem to be solved by the invention) However, according to the conventional example, since the sleeve and the backing plate are combined, it is difficult to control the dimensional accuracy of the welded part and the product (sleeve, backing plate), and the quality varies. This is easy to produce, requires time and effort to manufacture, and is therefore not suitable for mass production. When installing the sleeve, two full-circle welding points are required between the beam web and the sleeve, two circumferential welding points are required between the beam and one of the plates, and furthermore, two full-circumferential welding points are required between the beam web and the other backing plate. The plate also required welding around the entire circumference in 2 locations and a total of 6 locations.
There is still room for improvement from the standpoint of improving workability by reducing the weld length.

パ面として、梁６からの応力伝達を円滑にしている。Further, four temporary fixing holes 21 are transparently provided in the flange 2, and the temporary fixing holes are arranged at equal intervals along the outer circumference of the flange. One side surface 22 of the flange 2 (the left side surface in FIG. 1) is a contact surface that comes into contact with one side surface of the beam web 31, and the other side surface 23 is a tapered surface so that the flange becomes thinner toward the outer periphery. Stress transmission from the beam 6 is made smooth.

る。First, as shown in FIG. 1, insert the sleeve body 1 into the hole 32 of the beam web 31 from the left end side, and
2 is brought into contact with the web, and while in contact, the flange is temporarily secured to the web using bolts or welding using the temporary securing holes 21. Thereafter, the entire outer circumference of the flange 2 is fixed to the right side surface of the web by welding 4. Then, the groove 24 on the outer periphery of the sleeve body 1 in the beam through hole 32 is welded 41 from the left side of the web 31 to fix the sleeve body to the web.

の加工も簡単となる。According to Uebi, the other side surface 25 of the flange 2 is tapered,
The intersection of the flange base and the outer periphery of the sleeve body has the maximum wall thickness, eliminating sudden cross-sectional changes.
Stress transmission to the beam becomes smooth, stress concentration can be prevented, and high rigidity can be ensured. Although the temporary fixing holes 21 are not necessarily essential to the present invention, by providing a plurality of them, temporary fixing of the sleeve can be easily performed, a temporary fixing jig is not required, and it can also be used as a reinforcing hole for attaching a flange. can. Furthermore, if a groove 24 is formed at the base of the flange 2 as shown in the figure, processing time can be omitted compared to the case where the groove 24 is formed on the inner periphery of the grooved beam through hole 32.
Processing is also easier.

リーブと実質的に同一である。Other embodiments are shown in FIGS. 3 and 4. In this example, the diameter of the flange 12 is formed shorter than the upper side, and the side surface 123 is a vertical surface. As shown in FIG. 4, the groove 124 has six protrusions 124a protruding in the radial direction at equal intervals. This protrusion positions the sleeve body 1 with respect to the beam through hole 32. The rest of this sleeve is substantially the same as the upper sleeve in its construction and in the way it is attached to the beam web 61.

It facilitates quality control, eliminates the problem of quality variations, and is suitable for mass production. During installation, the number of welded parts can be reduced compared to conventional methods, and the weld length can be reduced, contributing to shortening the construction period.
