等の狭い所より搬入することができなかつた。 Conventional gate-shaped scaffolding consists of two parallel building blocks and a piece of fabric tied at one end. Generally, this scaffold is connected vertically and horizontally using joints and braces to assemble a framework scaffold. However, fabrics generally have a width of 610 mm to 1219 mm, making it impossible to transport them through narrow spaces such as manholes.
この考案は上記事情に鑑み創案されたものであ
る。以下図示する実施例により説明する。 This idea was devised in view of the above circumstances. This will be explained below with reference to the embodiments shown in the drawings.

鋼管2aには鋼管先端内に連結ピン9が嵌合する
嵌挿孔が設けられている。 As shown in FIG. 2, the connecting ends of the steel pipes 2a and 2b are provided with a plate-shaped bracket 3 protruding from the outside of the end of one of the steel pipes 2a, on which a connecting fitting 4 having a U-shaped cross section rotates. They are pivotally mounted with the bracket 3 sandwiched between them. Further, a nut 5 is fixed to the U-shaped end face of the connecting fitting 4, and a presser bolt 6 is screwed thereto. On the other hand, a locking piece 8 with a locking claw 7 protruding from the tip is fixed to the end of the steel pipe 2b, and a connecting pin 9 whose one end is inserted and fixed into the steel pipe 2b is attached to the outside. It stands out.
A fitting hole into which the connecting pin 9 is fitted is provided in the tip of the steel pipe 2a.

is fitted into the insertion hole of the steel pipe 2a, the bracket 3 and the locking piece 8 are aligned on the same plane, and the ends of the steel pipes 2a and 2b are butted together, and in this state, the connecting fitting 4 is rotated in the direction of the locking piece 8. A locking piece 2 is sandwiched in a groove having a U-shaped cross section in a connecting fitting 4, and a presser bolt 6 is screwed in, and its tip is pressed against the inside of a locking claw 7 of a locking piece 8.

結金具4をボルト6を緩めて外し、連結ピンを引
抜いて2つに分割し、片側の建地側にのみとする
ことにより、片側ずつを搬入し布地を連結し門型
足場として用いることができる。 This gate-shaped scaffold has the above-mentioned configuration, and the fabric 2 can be removed by loosening the bolt 6 of the connecting metal fitting 4, pulling out the connecting pin, dividing it into two parts, and attaching only one side to the building site. It can be used as a gate-shaped scaffold by bringing in fabric and connecting it with fabric.
また、連結金具と係止片とはボルトで締付け圧

で、鋼管の着脱の作業性が優れ、ボルトの紛失に
よるトラブルも起こらない。 In addition, since the connecting fitting and the locking piece are tightened and pressure-welded with bolts, there is no risk of the connecting pin loosening and coming off, resulting in high safety. Bolt tightening can be done easily even in narrow spaces, and the bolt can be attached to a nut fixed to a metal object. Since it is screwed on and can be tightened or loosened at any time, the workability of attaching and detaching the steel pipe is excellent, and troubles due to lost bolts do not occur.
