Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary assembly jig used for assembling an inner mold when manufacturing a hollow precast concrete column (referred to as an outer shell PCa column) and an inner jig using the same. The present invention relates to a method for assembling a mold.

[0002]

2. Description of the Related Art In an outer shell PCa column of this kind, an outer mold is arranged with a gap corresponding to a thickness outside an inner mold provided for forming a hollow portion. It is manufactured by pouring concrete into the space between the formwork. The problems in this case are the work of assembling the inner formwork, which requires work in a very narrow space, and the work of dismantling the inner formwork after the poured concrete has hardened.

[0003] For this reason, a method of eliminating the need for an inner mold by manufacturing the outer shell PCa column using a centrifugal apparatus, a method of directly using an air tube as the inner mold, or a method of using a metal lath wire mesh that does not require dismantling is used. A method of using the frame has been proposed.

However, the method of manufacturing using the centrifugal apparatus is substantially difficult to apply to manufacturing at a site where only a limited space is available because the apparatus is considerably large. In addition, the method of directly using the air tube as the inner formwork does not separate the air tube from the concrete surface at the time of disassembly, and requires cleaning of the surface for each product, and the air tube breaks while being diverted. There was a problem in diversion. In addition, when installing, after assembling the surrounding shear reinforcement (hoop muscle) and longitudinal main reinforcement, insert it into a narrow space, then send compressed air to inflate it, but surround it with the pillar hoop muscle. Inserting it tightly into a narrow space is very time-consuming, and it can cause the air tube to break because it was hooked on a reinforcing bar when it was inserted or on a reinforcing bar when inflated. was there.

[0005] On the other hand, in the case of the method using a metal lath wire mesh, although the above-mentioned problem does not occur, it takes time and effort to install the metal lath wire mesh inside the hoop streaks, and a member that is not originally required is required. There is a problem that the material cost increases due to the addition.

Accordingly, the present applicant has filed Japanese Patent Application No. 9-105.
No. 294 (Japanese Unexamined Patent Publication No. 10-278027), an inner mold apparatus having advantages such as requiring no skill in assembling, being easily workable in a site space on site, being excellent in peelability, and being easily diverted.
