したものから構成されるのが好ましいが、第６図に示す
ように中空でなく、概略Ｃ形断面のもの等がある。Further, members such as the cleat 2, the socket 3, and the stanchion 4 are also preferably made of aluminum, and in particular, the cleat 2 is a hollow body with integrally formed uneven parts on the top to prevent slipping, as shown in Fig. 4. It is preferable to be constructed from an extruded aluminum material cut to a predetermined size, but as shown in FIG. 6, it is not hollow but has a roughly C-shaped cross section.
しかるに従来の構造では、第７図および第８図に示すよ
うに、各クリート２の固定は溶接８によってなされたた
め前記のような欠点があった。However, in the conventional structure, as shown in FIGS. 7 and 8, each cleat 2 was fixed by welding 8, which resulted in the above-mentioned drawbacks.
この渡り足場は、中空の本体１の表面の両側の縁には、
その縁に沿って、幅方向に突出する一体の延長部１１が
備えられており、さらに好ましくは各延長部１１の縁に
は上方に突出する立上り部１２が一体に設けられている
。This crossing scaffold has two edges on both sides of the surface of the hollow main body 1.
Along its edges, integral extensions 11 are provided that project in the width direction, and more preferably, the edges of each extension 11 are integrally provided with rising portions 12 that project upward.
これらの延長部１１および立上り部１２は本体１の押出
成形と共に形成されるので、それらを設けるための特別
の手間を要しない。Since these extension portions 11 and rising portions 12 are formed together with extrusion molding of the main body 1, no special effort is required to provide them.
各延長部１１は渡り足場の表面と同一面に在るのが好ま
しく、その表面の幅寸法を若干大きくすると共に、以下
に述べるように各クリート２を連結部材により固定する
のを可能にする役割を果す。Each extension 11 is preferably flush with the surface of the crossing scaffold and serves to slightly increase the width of that surface and to allow each cleat 2 to be fixed by a connecting member as described below. fulfill.
なお、ここで用いる連結部材とはリベットまたはボルト
ナツトのことであって、連結部材としては図示のように
リベット９であるのが好ましいが、ボルトナツトであっ
てもナツトに適当なゆるみ止めを施こすことによってリ
ベットと同じ役割を果し得る。Note that the connecting member used here refers to a rivet or a bolt nut, and it is preferable that the connecting member is a rivet 9 as shown in the figure, but even if it is a bolt nut, it is necessary to apply an appropriate locking mechanism to the nut. can play the same role as a rivet.
また、立上り部１２は渡り足場の曲げ強さの向上に寄与
し且つ横方向のすべりを防止する役割を果している。Further, the rising portion 12 contributes to improving the bending strength of the crossing scaffold and plays a role in preventing lateral slipping.
各クリート２は中空のものでは第３図に見られるように
、両端が押潰されて平坦部２１になっており、その押潰
し加工はプレス等によって行なうことができる。If each cleat 2 is hollow, both ends are crushed to form a flat portion 21, as shown in FIG. 3, and the crushing process can be performed by a press or the like.
各平坦部２１には連結部材を通す孔をあけ、且つ本体表
面上のクリート２の取付位置における延長部１１の個所
にも孔をあけた上、各クリート２は両端の平坦部２１に
おいて延長部１１の所定位置にリベット９等によって固
定される。Each flat part 21 has a hole through which the connecting member passes, and a hole is also made at the extension part 11 at the mounting position of the cleat 2 on the surface of the main body. It is fixed at a predetermined position of 11 with a rivet 9 or the like.
従って、各クリート２の両端の平坦部２１はリベツティ
ングのためのものであるため、その寸法は必要最小限に
するのが好ましい。Therefore, since the flat portions 21 at both ends of each cleat 2 are for riveting, it is preferable to minimize their dimensions.
なお、第６図に示すような断面が概略Ｃ形のクリート２
では両端を押潰す必要がなく、そのまま固定される。Note that the cleat 2 has a roughly C-shaped cross section as shown in FIG.
In this case, there is no need to crush both ends, and it is fixed as is.
上記のように、本考案によれば、各クリートは渡り足場
