[0003]

Since the beams are projected from the columns in all directions, there are many restrictions on transportation. In addition, as a problem before transportation, when large assembly is performed in a factory, since there are many assembly pieces, careful construction is required to ensure product accuracy, and the number of man-hours in the factory is extremely large.

[0004] The present invention provides a method of manufacturing a beam-column joint capable of obtaining a beam-column joint capable of reducing restrictions on transportation and reducing man-hours in a factory.

[0005]

According to the present invention, there is provided a method of manufacturing a beam-column joint of a building, the method comprising firstly forming four sides and four corners at a predetermined place where the building is to be built. ,
Construct a steel column that is substantially square or rectangular in plan view. Then, each of the four steel beams having a horizontal flange is joined to a predetermined position on each side of the erected column with the horizontal flange substantially horizontal. Thereafter, the two beams within the corner interval defined by the two beams and the columns positioned adjacent to each other in plan view
Reinforcing diaphragms are welded to the horizontal flange of the beam and the side and corners of the column.

Another method of manufacturing a beam-column joint of a building according to the present invention is to first build a column in the same manner as described above. Before or in parallel with erecting the column, four steel beams having horizontal flanges, when each beam is joined to a predetermined position on each side of the column, a plan view A reinforcing diaphragm formed to fit alone or jointly with another adjacently positioned corner interval defined by the two beams to be positioned adjacent to each other and the column. Are prepared at predetermined positions on the horizontal flange of the required number of beams. Thereafter, each of these four beams is joined at predetermined positions on each side of the erected column with a horizontal flange substantially horizontal. Finally, the diaphragm is welded to the side portions and corners of the post within the corner spacing.

[0007]

According to the first invention, the beam is joined to the column after the column is erected at a predetermined position. Then, the horizontal flange of the two beams within the corner interval defined by the two beams and the columns positioned adjacent to each other in a plan view and the diaphragm extending to the side portion and the corner of the column are arranged. Welded.

In the second invention, a diaphragm having a predetermined shape is attached to the beam in advance, and the beam is joined to the side of the column, and then the diaphragm is welded to the side and the corner of the column.

Since the columns have no beams or diaphragms, there are few restrictions on transportation, and transportation efficiency can be improved.

[0010] Large assembly is easy in factory production. In addition, since the number of assembly pieces is small, it is easy to secure product accuracy. Therefore, cost can be reduced.

Since the number of man-hours for manufacturing a factory is very small,
It is possible to shorten the period from the production of the steel frame to the method of building on site. On the other hand, the number of on-site welding operations increases, but it is advantageous if a large number of on-site welding workers can be secured.
