Description
【発明の詳細な説明】 （産業上の利用分野） 本発明は塔状構造物の架構に適用される鉄骨建方ユニ
ツト足場工法に係るものである。DETAILED DESCRIPTION OF THE INVENTION (Industrial application field) The present invention relates to a steel-framed unit scaffolding method applied to a frame of a tower-like structure.
（従来の技術） 従来この種の施工においては、吊足場、籠足場等を架
設し、所要階の建方後、垂直ネツトを張設して次位の層
の建方に移行していた。(Conventional technology) Conventionally, in this type of construction, a suspension scaffold, a cage scaffold, and the like are erected, and after the required floor is constructed, a vertical net is stretched to shift to the construction of the next layer.
（発明が解決しようとする課題） 前記従来の方法は、足場の架設に多くの時間を要し、
しかも高所作業であるため危険を伴なう。(Problems to be Solved by the Invention) The conventional method requires much time for erection of a scaffold,
In addition, it is dangerous because it is a work at height.
また本設床が施工できないため、全層の足場を架設し
たのち、上層から順次足場の解体を行なわなければなら
ない。In addition, since a permanent floor cannot be constructed, the scaffolds must be dismantled sequentially from the upper layer after the scaffolds of all layers are erected.
特に梁が鋼管製の場合には、梁上の歩行が難しく、安
全養生材の架設、撤去ですら危険作業となる。更にまた
建方後にしか外部垂直ネツトの張設ができないために、
建方時にボルト、工具類の落下の危険を伴なう。In particular, when the beam is made of steel pipe, it is difficult to walk on the beam, and even erection and removal of the safety curing material is dangerous work. In addition, since the external vertical net can be stretched only after the construction,
There is a danger of bolts and tools falling during construction.

に構成されている。(Means for Solving the Problems) In order to achieve the above object, a moving steel framed scaffolding method according to the present invention employs a vertical steel frame on an outer edge of a work floor in which a net-like piece is stretched on a horizontal steel frame. A plurality of L-shaped unit scaffolds, which are formed by integrally connecting outer peripheral curing nets in which a net-like piece is stretched to a frame member and which can be inserted between adjacent pillars in a tower-like structure, are required to have a required construction. Installed on the beam on the floor, and at the time of rehabilitation, the L-type unit scaffold is suspended from the space between the tower pillars to the outside of the tower-like structure via a tower crane, and lifted to the next floor to start construction. It is configured to be inserted between adjacent tower columns on the floor.

物外側に吊出すように構成されている。The inner end of the work floor of the L-type unit scaffold is formed in a tower-like structure so that the steel beam is not damaged when the L-type unit scaffold is pulled sideways and the load posture is maintained when the L-type unit scaffold is lifted. A winch disposed in the center of the object supports the rope via a rope, and the winch is operated to lift the inner end of the work floor, and a load is lifted between the work floor and a lifting rope of the tower crane. After the posture maintaining chain block is provided, the link between the winch and the work floor is released, and then the L-type unit scaffold is suspended from the space between the tower columns through the tower crane to the outside of the structure. .
