「産業上の利用分野」
本発明は、ダム、橋脚等のコンクリート構造物
の構築に用いる移動式型枠におけるアンカー装置
に関するものである。DETAILED DESCRIPTION OF THE INVENTION "Field of Industrial Application" The present invention relates to an anchor device for movable formwork used for constructing concrete structures such as dams and bridge piers.
「従来の技術と発明が解決しようとする問題点」
ダム、橋脚等のコンクリート構造物の構築に
は、通常、型枠を上方へ盛替えてはコンクリート
を打継ぐいわゆるステツプフオーム工法がとられ
ている。``Problems to be solved by conventional technology and inventions'' When constructing concrete structures such as dams and bridge piers, the so-called step-form construction method is usually used, in which the formwork is moved upwards and concrete is then poured. There is.
この場合の型枠の盛替えは、数名の熟練工によ
つてクレーンを使用して行われることが多い。 In this case, the formwork is often replaced by several skilled workers using a crane.
しかし、この場合には、
1回に1ユニツトしか盛替えられず能率的で
ない。 However, in this case, only one unit can be replaced at a time, which is inefficient.
ダミーボルト、シーボルト、支持ボルト等の
ボルトの着脱作業に多くの労力と時間を要す
る。 It takes a lot of effort and time to attach and detach bolts such as dummy bolts, Siebolds, and support bolts.
高所作業となることが多く、クレーンで吊つ
た型枠上での作業にはかなりの危険が伴う。 Work often involves working at heights, and working on formwork suspended by a crane is quite dangerous.
作業員の豊富な経験と熟練を要する。 Requires extensive experience and skill on the part of workers.
などの欠点がある。There are drawbacks such as.
そこで、近年、型枠に自力上昇手段を講じた移
動式型枠が提案された(例:特開昭53−125330号
公報、特開昭54−63521号公報、特開昭54−
108430号公報)。 Therefore, in recent years, mobile formworks with self-lifting means have been proposed (e.g., JP-A-53-125330, JP-A-54-63521, JP-A-54-
Publication No. 108430).
しかし、この場合には、上昇手段により型枠を
上昇させることはできても、ダミーボルト、シー
ボルト、支持ボルト等の着脱については未だ人力
に頼られており、
ボルトの着脱作業に多くの労力と時間を要す
る。 However, in this case, although it is possible to raise the formwork using a lifting means, the attachment and detachment of dummy bolts, Siebolds, support bolts, etc., still relies on manual labor, and it takes a lot of effort to attach and detach the bolts. It takes time.
ボルト着脱作業に足場が2段必要となる。 Two levels of scaffolding are required to attach and remove bolts.
などの欠点がある。There are drawbacks such as.
本発明は、斯る従来の欠点を除去しようとする
ものである。 The present invention seeks to eliminate such conventional drawbacks.
