Description

本発明は、建築営造用の中空薄殻柱体に関し、詳しく言えば、中空薄殻柱体の製造方法及び成形装置に関するものである。   The present invention relates to a hollow thin shell column for building operation, and more particularly to a method for manufacturing a hollow thin shell column and a molding apparatus.

一般的に、ビルを建造する場合、骨組みは鉄筋コンクリートから構成される骨組みと鋼鉄から構成される骨組みなどに分けられている。鉄筋コンクリートから構成される骨組みを採用して建造する形態は、下記の通りである。一つは、ビルの施工現場で鉄筋及びプレートを架設してコンクリートを流し込んで支柱を形成することである。もう一つは、成形工場で中空薄殻柱体を予め製造し、その後、ビルの施工現場に搬入し、組立ての施行法により基部または梁と結合することである。前者の方法を採用してビルの支柱を建造する場合、支柱基部の位置に鉄筋とプレートをあらかじめ架設して固定することを必要とし、その後、コンクリートを流し込んでプレート中のコンクリートが固まるまで、次の工程が進まないため、建造時間が長くなり、ビルの施工期間が延びる可能性がある。後者の方法を採用してビルの支柱を建造する場合、成形工場で中空薄殻柱体をあらかじめ製造することが可能であるが、中空薄殻柱体は鉄筋とコンクリートから構成された支柱で、重量が極めて大きいため、搬送及び現場施工に不便な点があるだけではく、コストを増加させる。   Generally, when building a building, the framework is divided into a framework composed of reinforced concrete and a framework composed of steel. The form of construction using a skeleton composed of reinforced concrete is as follows. One is to build up the reinforcing bars and plates at the construction site of the building and pour concrete into the columns. The other is to pre-manufacture a hollow thin shell column in a molding factory, and then carry it into a building construction site and combine it with the base or beam according to the assembly method. When building the column of the building using the former method, it is necessary to lay and fix the reinforcing bar and the plate in advance at the position of the column base, and after that, until the concrete in the plate is solidified by pouring the concrete Since this process does not proceed, the construction time becomes longer and the construction period of the building may be extended. When building the pillar of a building using the latter method, it is possible to manufacture a hollow thin shell column in advance at a molding factory. However, the hollow thin shell column is a column composed of reinforcing steel and concrete, and is extremely heavy. For this reason, not only is there inconvenience in transportation and on-site construction, but the cost is increased.

したがって、本発明者は、成形材料の重量を減らすことで、吊り上げ、搬送及び組立などの作業を容易にし、かつ梁柱の品質を強化し、工期短縮と生産力向上を実現させ、そして、上述の欠点を有効改善することを可能にする中空薄殻柱体の製造方法及び成形装置を提出する。   Therefore, the inventor reduces the weight of the molding material to facilitate the operations such as lifting, conveying and assembling, strengthening the quality of the beam column, shortening the work period and improving the productivity, and A manufacturing method and a forming apparatus of a hollow thin shell column that can effectively improve the drawbacks of the present invention are submitted.
