Furthermore, the manufacturing process is time-consuming and is not suitable for mass production. 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. Also, in this sleeve,
Since a backing plate is also required on the back side of the web, the number of parts increases accordingly, and the number of installation steps increases, which does not contribute to shortening the construction period. When welding the backing plate of the sleeve, a temporary fixing jig is required for temporarily fixing the sleeve, and moreover, the temporary fixing with the jig requires time and effort.

により接合する部分である。 The material for casting the beam penetrating sleeve is selected from materials compatible with the structural material of the beam 3, such as iron, light alloy, FRP, etc. Outer periphery 11 of sleeve body 1
is formed so that its wall thickness gradually increases from both ends of the sleeve body toward the base of the flange 2, and reaches its maximum thickness at the intersection with the base. The outer shape of the flange 2 is similar to that of the web 31 of the beam 3.
The size is set such that it can be positioned within the beam through hole 32 provided in the. Further, a groove 21 is provided on the outer peripheral edge of the flange, and a substantially K-shaped groove is formed between this outer peripheral edge and the inner peripheral part of the beam through hole 32. Although it is desirable to provide the groove at the outer peripheral edge of the flange, the groove 33 may be provided at the inner peripheral portion of the beam through hole by cutting, as shown in FIG. 3A. 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 welded 4 to the inner peripheral part of the beam through hole 32.
This is the part to be joined by.
次に梁貫通スリーブの取付けについて説明す

となり、取付け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 molded, there is no need for assembling work by welding the sleeve body and the plate as in the past. This makes management easier, eliminates the problem of quality variations, and further improves mass production. During installation, only one welding point is required, on the outer peripheral edge of the flange, and the welding length can be reduced compared to the conventional example, helping to save labor and eliminating the problem of eccentricity of the beam due to welding distortion. Since the outer periphery of the sleeve body is formed to gradually become thicker from both ends of the sleeve 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. Furthermore, since both sides of the flange are tapered so that the wall thickness of the flange becomes thinner toward the outer periphery, stress transmission through the beam becomes smooth. The temporary fixing stopper provided on the flange eliminates the need for a temporary fixing jig, simplifying the installation work.
