Description

【0001】
【発明の属する技術分野】
本発明は、工事現場などに設置される仮設足場や資材置場等に設けられる簡易扉に関するものである。
【0002】
【従来の技術】
高架道路の補修などに使用する仮設足場あるいは養生枠で囲った資材置場などの出入口には、一般の人が侵入できないように扉を設ける必要がある。この種の扉は、吊元側をヒンジで開閉自在に支持し、自由端側のロック機構で施錠するのが一般的であり、本発明に関連する先行技術として例えば特許文献1がある。
【0003】
この特許文献1の発明は、工事現場などの出入口等に仮設される仮設門扉用のくぐり戸であり、扉本体を囲むように長方形状の外枠を設け、扉本体と外枠の縦枠同士をヒンジ(丁番)で連結し、ロック機構のラッチ錠やシリンダ錠などの錠扞が挿入される係合穴を外枠の縦枠に設けている。また、外枠の左右一対の縦枠とパネルの左右一対の支柱とがそれぞれ、縦枠に取付けたクランプ取付部材と、支柱を抱持するクランプにより固定されている。
【0004】
【特許文献1】
特開2002−38857号公報
【0005】
【発明が解決しようとする課題】
従来の特許文献1の発明の場合、扉本体の外側を取り囲む長方形状の外枠が必要であり、扉本体と外枠の間にヒンジ部品とロック部品を設け、外枠をクランプ取付部材とクランプによって支柱に取付けるため、扉構造が複雑であり、部材点数も増え、また取付けも面倒であるなど、資材置場や仮設足場等に設ける簡易扉には、適しているとはいえない。
【0006】
本発明は、仮設足場や資材置場等に設けられる扉を簡易な構造とすることができ、取付けも極めて容易なものとすることができ、しかも、人の侵入を確実に防止することのできる簡易扉とそのヒンジ装置及びロック装置を提供することを目的とする。
【0007】
【課題を解決するための手段】
本発明の請求項1は、仮設足場や資材置場等の左右一対の支柱間に取付けられる簡易扉であり、扉本体の吊元側のヒンジ部品がクランプを介して一方の支柱に固定され、扉本体の自由端側のロック部品がクランプを介して他方の支柱に固定されていることを特徴とする簡易扉である。左右一対の支柱は、仮設足場の場合は建枠の建地、資材置場の場合は養生枠を取付ける支柱である。
【0008】
本発明の請求項2は、請求項1に記載の簡易扉において、扉本体がメッシュ扉であることを特徴とする簡易扉である。メッシュ扉は、扉枠にワイヤーメッシュを取付けて構成する。広巾の建枠等の場合、狭巾用の扉本体に追加用の扉本体をボルト・ナットで接続して広巾の扉本体とすることができる。
【0009】
本発明の請求項3は、仮設足場や資材置場等の左右一対の支柱間に取付けられる簡易扉のヒンジ装置であり、前記支柱の外周に取付けられる基体と抱持体とを締結ボルトで緊結してなるクランプの基体に、ヒンジ部品のヒンジボルトが挿入されるクランプ側のヒンジ管が一体的に設けられていることを特徴とする簡易扉のヒンジ装置である。扉本体の吊元側にも扉側のヒンジ管を取付けておく。
【0010】
本発明の請求項4は、仮設足場や資材置場等の左右一対の支柱間に取付けられる簡易扉のロック装置であり、前記支柱の外周に取付けられる基体と抱持体とを締結ボルトで緊結してなるクランプの基体に、ロック部品の扉本体の自由端側を係止可能なフックを有するスライダを水平スライド自在に支持するスライダ受けが一体的に設けられていることを特徴とする簡易扉のロック装置である。スライダとスライダ受けには、施錠状態で上下に重なり合う水平の固定片を設けておき、南京錠等で施錠する。
【0011】
上記のヒンジ装置及びロック装置のクランプには、建地や足場管などの2種類の径に対応できる兼用クランプを用いるのが好ましい。また、建枠の場合には、ヒンジ管やスライダ受けをクランプに直接溶接等で固定する。資材置場の場合は、連結部材を介在させて溶接等で固定し、養生枠の端部をクランプの横に配置して固定できるようにする。
【0012】
以上のような構成において、ヒンジ管が一体的に設けられたクランプを一方の支柱に固定し、スライダ受けが一体的に設けられたクランプを他方の支柱に固定し、扉本体の吊元側のヒンジ管と上記のクランプのヒンジ管にヒンジボルトを挿入して扉本体を開閉自在に取付ける。扉本体を閉じて、スライダを水平スライドさせてスライダのフックを扉本体の自由端側の縦枠に係合させれば、扉本体の開きが阻止される。スライダとスライダ受けの上下に重なり合う水平の固定片に南京錠等を掛ければ、確実に施錠される。
【0013】
以上のような本発明によれば、仮設足場や資材置場等の支柱にヒンジ部品やロック部品をクランプを介して直接取付けるため、従来のような扉本体の外側を取り囲む長方形状の外枠や、外枠を支柱に取付けるクランプ取付部材及びクランプが不要となり、簡易な扉構造で、部材点数も少なく、また取付けも極めて容易に行うことができ、簡易で低コストの扉が得られる。しかも、クランプとヒンジ部品及びロック部品が一体となっており、人の侵入を確実に防止することができる。また、扉本体を上下反転すれば、反対開きとすることができる。
