Description
【発明の詳細な説明】 「産業上の利用分野」 本発明は、鉄骨建方法に関する。Description: FIELD OF THE INVENTION The present invention relates to a steel frame construction method.
「従来の技術」 従来の鉄骨建方は、骨組架構の形状，重量が運搬上の
制約を大きく受けることから、単材の形で現場に運搬し
たのち、タワークレーンあるいは移動式クレーンによる
積上げ方式でもって立体的に骨組架構を組立てている。"Conventional technology" In conventional steel frame construction, since the shape and weight of the framed structure are greatly restricted in transportation, they are transported to the site in the form of a single material and then stacked using a tower crane or mobile crane. The frame structure is assembled three-dimensionally.
叙上クレーンは、単材の重量及び作業半径，鉄骨構築
物の高さ等から選定される。The lifting crane is selected based on the weight and working radius of the single material, the height of the steel structure, and the like.
「発明が解決しようとする課題」 しかし、従来の建方では、 （１） 単材を現場で組立てるものであるので、構築時
間が長くかかり、また、仕口誤差が重って大きな累積誤
差となり、本接合前の建直し調整にかなりの手間を要す
る。"Problems to be Solved by the Invention" However, in the conventional construction method, (1) Since a single material is assembled on site, it takes a long construction time, and a large accumulation error due to a large overlap error. However, it takes a considerable amount of time to adjust the rebuilding before the actual joining.
（２） 作業の大部分が高所で行われることとなるた
め、作業が困難で作業能率が低上に危険が多く工期も長
くかかるが、高所で組立て作業を行なうとび職の技能は
一般的に低下してきており、また高所作業に要求される
仮設安全対策はより厳しくなってきているという難点が
ある。(2) Since most of the work is performed at high altitudes, the work is difficult, the work efficiency is low, and there are many dangers and the construction period is long, but the skill of assembling work at high altitude is common. The problem is that temporary safety measures required for work at heights are becoming stricter.
（３） 構築物が高くなれば大型のクレーンを使用しな
ければならないため、その輸送費や稼働費は膨大なもの
となり、更にトラッククレーンはもちろんのこと、クラ
イミングクレーンを用いる場合にも、構造物の外側に設
置しなければならず、クレーン据付のためのかなり広い
余分なスペースとクレーン設備のための基礎工事または
地盤の養生を要するが、ほとんどの現場は、周囲に建物
が密集していることが多いことなどにより、材料の搬
入、取扱い、足場の確保などが難かしいこと、または障
害物であって、クレーンの搬入が不可能な現場には対応
し得ない。(3) If the structure becomes high, a large crane must be used, so the transportation and operating costs become enormous. Furthermore, not only when using a truck crane but also when using a climbing crane, the structural It must be installed outside and requires a fair amount of extra space for crane installation and foundation work or ground curing for crane installations, but most sites have a dense surrounding building Due to the large number, it is difficult to carry in, handle, and secure a scaffolding of materials, or it is impossible to cope with an obstruction where a crane cannot be carried in.
等の問題点がある。And so on.
本発明は、単材の組立てを不安定な足場のもとでする
ことなく、充分な管理が期し得る地組みにてなし得ると
共に別段大型のクレーンを必要とすることなくして僅か
な高所作業のみでもって建方がし得る従来手段の難点の
起因である大型クレーンを必要とする高所作業での単材
の組立てという常識から脱した新規な鉄骨建方法を提供
することを目的としている。The present invention is capable of assembling a single piece of material on an unstable scaffold, in a terrain where sufficient control can be expected, and working at a slightly higher place without the need for a specially large crane. It is an object of the present invention to provide a new steel building method which departs from the common sense of assembling single materials at a high place requiring a large crane, which is one of the drawbacks of the conventional means that can be built only by a conventional method.
「課題を解決するための手段」 上記目的を達成するために、本発明の鉄骨建方法は、
隣立する本設鉄骨群中の少なくとも安定架構最小単位分
の本設鉄骨を、その基端を所定位置にピン止めした状態
で小型クレーンで地組みし、次いで起立させて組付けて
少なくとも安定架構最小単位分を完成させ、以下、順次
隣接位置の本設鉄骨をその基端をピン止めした状態で小
型クルーンで地組みし、これを先行起立の本設鉄骨上端
に配置した滑車を介してウインチで起立させると共に当
該先行起立本設鉄骨にジョイントさせていって鉄骨架構
を構築し、建直し調整のうえ該ピン止め部を固定すると
したものである。"Means for solving the problem" In order to achieve the above object, the steel-frame building method of the present invention,
At least the minimum unit of the stable steel frame of the adjacent group of permanent steel frames is erected with a small crane with its base end pinned at a predetermined position, and then erected and assembled to at least the stable frame. After completing the minimum unit, the main steel frames at the adjacent positions are sequentially laid with small crunes with their base ends pinned, and this is winched via a pulley arranged at the upper end of the front standing main steel frame. Then, the steel frame is connected to the pre-standing standing steel frame to construct a steel frame, and the pinned portion is fixed after rebuilding and adjustment.
「作用」 上記のように構成された本発明の工法によるならば、

して高層架構が立ち上がることとなる。[Operation] According to the method of the present invention configured as described above,
The main steel frame is finished with high quality and quick by the terrain,
When assembling, a small crane is sufficient. The finished steel frame is pinned at the base end, so that it can be easily raised by a winch, and a high-rise frame can be raised without using a crane.
高所作業は、先行起立の本設鉄骨に対しての後行起立
の本設鉄骨に付設の持ち出し梁のジョイントのみであ
り、単材を組立てる従来手段に比し極めて少なくなる。The work at height is only a joint of a take-out beam attached to the main standing steel frame of the preceding standing main steel frame with respect to the preceding standing main steel frame, which is extremely small as compared with the conventional means of assembling a single member.
