ある。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application 1] The present invention relates to a structure of a PCa (precast concrete) column, particularly a hollow PCa column having a cross-sectional shape.
［従来の技１１Ｆｊ］

筋を配しない型枠のみのものがあった。[Conventional Technique 11Fj] Conventionally, this type of hollow PCa column has been constructed by integrally arranging hoop reinforcements as shown in Fig. 4, or by reinforcing only the lower part of the column as shown in Fig. 5. Some were hollow, and others were only formwork without reinforcing bars.

ある等の間Ｎ魚があった。[Problem to be solved by the invention 1 However, in the case where only the hoop reinforcement is arranged, the column main reinforcement is set later, so there are problems such as insufficient rationalization of construction on site. There are points, and
Columns that are hollow at the bottom only have problems such as having a lot of swollen concrete and are time-consuming to work with, and those that only have formwork cannot be included in the strength calculations as a frame, so the shape of the column is There were N fish during the period when the fish became large and uneconomical in terms of cost.

荷重を受けることがで終るようになっている。Furthermore, as is particularly clear from FIG. 3, the inner wall surface of the hollow column body 1 is provided with a sure connector 4 having an annular groove in the horizontal direction, and is connected to the concrete that is optically layered at the site. It is designed so that it can be integrated and bear the load as a frame over its entire cross section.
