2. Description of the Related Art When joining structural members such as studs to a steel beam, it is necessary to reinforce the joints with rib plates or the like.
However, welding of rib plates is poor in manual workability, and quality control is difficult. On the other hand, the structural members and their joints that are joined to the beams vary depending on the building and its parts.
If beams prepared by welding rib plates to only the necessary parts are prepared, there will be too many types, and quality control and automatic welding will be difficult. Therefore, when the steel frame beam is prefabricated, as shown in FIG. 8, the rib plates 43 are attached to all the portions where structural members such as the studs 42 of the steel beam 41 and the brace panel (not shown) may be attached. It is customary to weld.

According to the beam-reinforcing structure having this structure, since the reinforcing metal member 13 is attached by the axial fastener, the beams 4, 5 are attached.
The shaft-shaped fastener can be easily attached without welding by only providing the through holes 12A and 12B for the shaft-shaped fastener. Therefore, the beams 4 and 5 to which the structural members such as the brace-reinforced frames 2 and 2A and the studs 18 are attached are different from each other, and only the place where the reinforcement is required can be performed without complicating the member management and reducing the productivity. The cost can be reduced by eliminating unnecessary work and members. Since the reinforcing metal member 13 is adapted to be joined to the inner surface of the flange of the beams 4 and 5 and the inner surface of the web, it can be firmly attached and the size between the upper and lower flanges 4a, 4b, 5a and 5b of the beams 4 and 5 can be increased. The same joining hardware 13 can be used to deal with tolerances and beam differences. Further, since the joining work of the reinforcing hardware 13 also serves as the joining work of the bracing reinforcement frames 2 and 2A and the stud 18, the working man-hour can be reduced accordingly. Furthermore, the beams 4,
No. 5 can be completely weldless by combining the structure in which the column 3 is bolted and the reinforcing metal 13 is bolted, and the unit box 1 can be welded to a higher degree to improve productivity. It is possible to improve the reliability and the reliability.
