〔産業上の利用分野〕
本考案は、集水、汚水桝又は下水道用のマンホ
ール等のコンクリート製品のコア（芯材）抜き装
置に関するものである。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device for removing cores from concrete products such as manholes for water collection, sewage basins, and sewerage.
従来一般に行なわれているこの種のものは、
イ 木材による木枠組立てによるもの、
ロ 鉄枠によるもの、
ハ 発泡スチロールを使用する方法、などがあ
る。
Conventionally common methods of this type include (a) assembling a wooden frame using wood, (b) using an iron frame, and (c) using styrofoam.
前述の従来の技術において、先ず
イの木枠組立てによるものは、木材の消費量
と、木枠組立時の工数等の点からして非常に不経
済であると共に、木枠を取外す際、コンクリート
製品に対してハンマー、バール等を使用する為
に、製品に損傷を与えるなどで品質の低下を来た
すような問題点がある。
Among the conventional techniques described above, first, the method of assembling a wooden frame in (a) is extremely uneconomical in terms of wood consumption and man-hours when assembling the wooden frame, and when removing the wooden frame, it is difficult to assemble the wooden frame. Since hammers, crowbars, etc. are used on the product, there are problems such as damage to the product and deterioration of quality.
ロの鉄枠法は、半永久的ではあるが、脱型の為
の抜き勾配がある為、不定形である位置にはセツ
トすることが出来ず、ペースト漏れが発生する。
更に鉄枠は重量がかかり、一人の作業員では取付
けが出来ず、従つて作業性が悪く、又取り外しの
際に、ハンマー等を使用するので、製品に角欠
け、クラツク等の損傷を与え品質低下などの問題
点がある。 Although the iron frame method (b) is semi-permanent, it has a draft angle for demolding, so it cannot be set in an irregularly shaped position, and paste leakage occurs.
Furthermore, iron frames are heavy and cannot be installed by one worker, making them difficult to work with. Also, since a hammer or other tool is used to remove them, the product may suffer damage such as chipped corners or cracks, resulting in poor quality. There are problems such as decline.
ハの発泡スチロール法では、比較的作業性は良
好であるが、スチロール材の消費量が多く、甚だ
不経済であるなどの問題点がある。 The foamed polystyrene method (C) has relatively good workability, but has problems such as a large amount of styrene material being consumed and being extremely uneconomical.
本考案は、上記のような種々の問題点を除去す
ることを目的とする。 The present invention aims to eliminate the various problems mentioned above.
