り、省力化、工期短縮等から改善が要望された。 Conventionally, reinforced concrete or steel structures are often pre-assembled to the required size on the ground and then assembled on site. However, in the case of steel frames and reinforced concrete structures, even if the steel frames are pre-assembled, the reinforcing bars are placed on-site around the erected steel frames, and improvements have been requested to save labor and shorten the construction period.

In the figure, main reinforcing bars 2 and hoop reinforcing bars 3 are preassembled in a cage shape around a column steel frame 1 made of H-shaped steel or the like. At this time, the steel frame 1 is used as a support, retaining rods 4 are assembled around the steel frame 1 in a cross-shaped configuration, and the main reinforcing bars 2 are tied and attached to the retaining rods 4 to form a prefabricated unit.

骨は梁型枠，床型枠の支保工として利用できる。 Figure 4 shows another embodiment in which the column steel frame 1 and one beam steel frame 10 are integrally connected, the column steel frame 1 is used as a support, the main reinforcing bars 2 are attached, and the hoop bars are shaped like cages. The beam main reinforcing bars 12 and stirrups 13 are attached to the beam steel frame 10 as well.
The columns are pre-assembled to form a cage-like structure, and a prefabricated unit of column, beam, and steel frames and reinforcing bars is constructed. Next, this prefabricated unit is lifted up. In this case, the beam in the other direction may have either a reinforced concrete structure or a steel reinforced concrete structure. Additionally, the one-way beam steel frame can be used as support for beam formwork and floor formwork.

げる。 Figure 5 shows a beam steel frame 10 integrally connected to a column steel frame 1 in both directions, with the column main reinforcing bars 2 and beam main reinforcing bars 12 attached in a cross-shaped manner using the column steel frame and beam steel frame as supporting materials. As shown in the figure, the reinforcing bars of each column and beam are pre-assembled in a cage-like manner to form a prefabricated unit of column and beam steel frames and reinforcing bars, which is then lifted up.

は現場作業がなくなり、より施工が容易である。 In the second and third embodiments, columns, beams, and floor concrete are cast at the same time, but other construction procedures are substantially the same as in the first embodiment. Furthermore, in these embodiments, the reinforcement arrangement in the panel zone portion is simplified or on-site work is eliminated, making construction easier.

業能率が向上する。 This invention has the above structure, and when constructing a steel reinforced concrete structure, the steel frames and reinforcing bars are pre-assembled and prefabricated as much as possible, resulting in significant labor savings on site.Also, the steel frames are allowed to stand on their own before being connected to the reinforcing bars. This makes construction safer, and prefabrication improves accuracy, shortens construction time, and improves work efficiency.
