次に第４図、第５図によりワーゲンＷ後退時の作業方法
を説明する。Next, a working method when reversing the Volkswagen W will be explained with reference to FIGS. 4 and 5.
初めに第４図のように橋桁８幅方向の両端に張られた斜
材Ｃの両外側に仮設レール４，４を橋桁ａ長さ方向に敷
設する。First, as shown in FIG. 4, temporary rails 4, 4 are laid in the length direction of the bridge girder a on both outsides of the diagonal members C stretched at both ends of the bridge girder 8 in the width direction.
この敷設作業と並行して、または敷設後仮設レール４上
を走行可能な車輪５ａを有する支持部材５を吊柱２．２
の内側に突設し、これによって吊柱２，２及び足場３を
支持する。In parallel with this laying work or after laying, the supporting member 5 having wheels 5a that can run on the temporary rail 4 is attached to the hanging pillar 2.2.
The suspension pillars 2, 2 and the scaffolding 3 are supported by this.
続いて第５図のように少なくとも架設梁１ａの斜材Ｃと
交差する部分を取り外してワーゲンＷを後退可能とする
。実施例では架設梁１ａとともに吊柱２，２の一部も取
り外している。Subsequently, as shown in FIG. 5, at least the portion of the construction beam 1a that intersects with the diagonal member C is removed to enable the wagon W to retreat. In the embodiment, part of the hanging columns 2, 2 is also removed along with the construction beam 1a.
第４図において中心線の左側は第３図のＸ−Ｘ線断面、
右側はＹ−Ｙ線断面を示しているが、Ｙ−Ｙ線断面に示
すようにワーゲンＷの前面に配置される吊柱２も取り外
される。In Figure 4, the left side of the center line is the cross section taken along the line X-X in Figure 3;
The right side shows a cross section taken along the line YY, and as shown in the cross section taken along the YY line, the hanging pillar 2 disposed on the front of the Volkswagen W is also removed.
そして第５図の状態でワーゲン本体１と吊柱２．２とを
それぞれ個別に主塔すまで後退させる。Then, in the state shown in FIG. 5, the wagon main body 1 and the hanging pillars 2.2 are individually retreated to the main tower.
ワーゲン本体１の後退は前進と逆の操作により行われ、
また吊柱２，２はワーゲン本体１の後退と同じく駆動装
置等により後退させられる。The backward movement of the main body 1 of the Volkswagen is carried out by the reverse operation of the forward movement.
Further, the hanging pillars 2, 2 are moved back by a drive device or the like in the same way as the wagon main body 1 is moved back.
ワーゲン本体１と吊柱２，２は共に主塔すにおいて分割
・解体され、撤去される。The main body 1 of the wagon and the hanging pillars 2, 2 are both divided and dismantled at the main tower and removed.
