必要として、その上治具による仮止め手業を要する。(Problem to be solved by the invention) However, according to the conventional example, as a combination of a sleeve and two backing plates, it is necessary to weld them to the beam web. It is difficult to control the quality of the dimensional accuracy of the dimensional accuracy of the plate, the quality is likely to vary, and the manufacturing process is time-consuming, making it unsuitable for mass production. And when installing the sleeve,
The beam web and sleeve are welded in two places around the entire circumference.
Two full-circle welds are required for the beam and one backing plate, and two full-circle welds are required for the beam web and the other backing plate, making it a total of six places. There is still room for improvement from the standpoint of reducing the amount and improving workability. Furthermore, since the amount of welding is large, the web of the beam is likely to curve due to welding distortion. Furthermore, this sleeve requires a backing plate on the back side of the web, which increases the number of parts and increases the number of installation steps, which does not contribute to shortening the construction period. In addition, when welding the backing plate of the sleeve, a temporary fixing jig is required for temporarily fixing the sleeve, and additionally, temporary fixing work using the jig is required.

り固定することにより行う。(Means for Solving the Problems) The beam penetrating sleeve of the present invention is obtained by integrally molding a sleeve body 1 and a flange 2 located on the outer periphery of the body by casting. The outer periphery of the sleeve body 1 is connected to the flange 2 from both ends.
It becomes thicker toward the intersection with the 0 base. The diameter of the flange 2 is such that it can be positioned within the beam through hole 32, and the outer peripheral edge of the flange can be welded to the inner peripheral portion of the beam through hole. Furthermore, a stopper 22 for temporarily fixing the sleeve is integrally formed on one side of the flange 2, and the end of this stopper can come into contact with the edge of the beam through-hole. To attach the beam penetrating sleeve to the cast beam 5, insert the sleeve body 1 into the beam through hole 32, position the flange 2 in the hole, and then weld the outer peripheral edge of the flange and the inner peripheral portion of the hole. This is done by fixing with 4.

梁貫通孔３２の内周部に溶接４により接合可能である。As shown in FIGS. 1A and 2A, the beam penetrating sleeve consists of a sleeve body 1 and a prototype flange 2 provided approximately at the center of the outer periphery of the sleeve body. The sleeve body 1 and the flange 2 are integrally formed by casting using cast steel. The wall thickness of the outer peripheral portion 11 of the sleeve body 1 is 7 rank 2.
It gradually becomes thicker toward the 0 base, and reaches its maximum thickness at the intersection with the base. Further, the outer diameter of the flange 2 is set to a size that allows it to be positioned within a beam through hole 32 provided in the web 31 of the beam 3. Furthermore, there is a groove 2 on the outer peripheral edge of the flange.
1 is provided, and a substantially shaped groove is formed between this edge and the inner circumference of the beam through hole 32. Although it is desirable to provide the groove on the outer peripheral edge of the flange, the groove 33 may be provided on the inner peripheral portion of the beam through hole by cutting, as shown in FIG. 6A. Providing the groove on the flange side has the advantage that it can be formed at the same time as the sleeve is formed, so cutting is not required and the beam can be manufactured easily. The outer peripheral edge of the flange 2 is
It can be joined to the inner peripheral part of the beam through hole 32 by welding 4.
次に梁貫通スリーブの取付けについて説明する。Next, installation of the beam penetrating sleeve will be explained.

In the case of , it is necessary to temporarily fix the sleeve to the beam using sleeve temporary fixing means before welding. The distance is the distance from the flange 2 to the left end of the sleeve body 1, as shown in FIG. 1A, and the distance D1 is the distance from the center position of the flange of the beam 3 to the left end.
ここで仮止め手段の一例を第１Ｂ〜３Ｂ図を参照して説

作業が単純化できる。(Effects of the Invention) As explained above, according to the present invention, since the sleeve body and the flange are integrally formed by casting, there is no need for the conventional assembly work of welding the sleeve body and the plate. Quality control becomes easier, the problem of quality variations can be solved, and mass productivity is further improved. During installation, the welding point is only one location on the outer periphery of the flange (compared to the conventional example), the weld length can be reduced, which helps save labor during construction, and eliminates the problem of eccentricity of the beam due to welding distortion. Since the outer circumference of the sleeve body becomes thicker toward the base of the flange, a high reinforcement effect of the beam through-hole can be expected. Furthermore, there is no need to retrofit the conventional backing plate. The temporary fixing stopper provided on the flange eliminates the need for a temporary fixing jig, simplifying the installation process.
