したものである。The structure of this invention is that the ladder frame is attached to both ends of the scaffold board so that it can be folded and protruded downward, and the ladder frame is held in such a way that it can be attached to and detached from the fly 1-.
The latches that support the rungs of the ladder frame are fixed, and the ladder frames on both sides are connected using scaffolding boards to make the ladder stand on its own.

以下、この発明を添付図面の実施例Ｇこ基づいて説明す

定した掛止−ｊ！、４、４とで構成されている。As shown in the figure, the work scaffold consists of a scaffolding board 1, holders 2.2 attached to both ends of this scaffolding board 1, and each holder 2.2.
A pair of ladder frames 3.3 held by 2G and a scaffold board 1
The hooks -j fixed at both ends Q of the scaffolding board 1 so as to connect the ladder frame 3.3 and the ladder frame 3. , 4, and 4.

字形の掛止具４が固定されている。1a by U-shaped rods 1b at both ends, and a horizontal U-shaped rod is formed on the outer end surface of both U-shaped rods 1b.
A letter-shaped hook 4 is fixed.

に回動自在となるように取付けられている。The holder 2.2 includes a pair of hinges 5 fixed to both ends of a U-shaped rod 1b so as to protrude diagonally outward from the bottom, a guide frame 6 assembled in a U-shape using pipes, and 1. The guide frame 6 is formed by a combination of holding fittings 8 fixed to both ends of both parallel parts 7 of the guide frame 6 and a bi-fold rod 9.
It is mounted so that it can rotate freely.

の配置になる。The bi-fold rod 9 connects the horizontal part 11 of the guide frame 6 and the lower surface of the scaffold board 1, and when the bi-fold is rubbed, the guide frame 6 becomes parallel to the lower surface of the scaffold board 1 as shown in FIG. The guide frame 6, which is folded and straightened, is maintained in a state extending obliquely from the end of the scaffolding board 1 to the lower part and outward from the end of the scaffolding board 1, centering on the pivot shaft 10, as shown in FIG. 2 at both ends of the scaffolding board 1. It becomes a V-shaped arrangement.

長手方向に移動自在となるよう取付けられる。The ladder frame 3.3 has treads 3b installed horizontally at regular intervals between vertical columns 3a on both sides, and grounding legs 3c at the lower ends of the vertical columns 3a and '3a.
Both vertical pillars 3as3a are formed at an equal distance O from both parallel parts 7.7 of the holder 2, and the vertical pillars 3a are held by the parallel parts 7 and the holding fittings 8 as shown in FIG. Therefore, the ladder frame 3 is attached to the holder 2 so as to be movable in its longitudinal direction.

ｂを掛止具４に掛合させることができる。The latches 4 fixed to both ends G of the scaffolding board 1 are formed in a horizontal U-shape into which the treadle 3b can be fitted, and when the holder 2 is made into a V-shape as shown by the solid line in FIG. When hooked to the hook 4, the ladder frame 3 is prevented from moving up and down and the scaffold board 1
The work scaffold becomes independent, and
When the bifold rod 9 of the holder 2 is bent as shown by the dashed line in FIG. 3, the ladder frame 3 rotates together with the guide frame 6.
Since the treadle 3b is removed from the hook 4, the ladder frame 3 can be moved freely in the vertical and longitudinal directions, and the treadle 3 can be placed at a desired height.
b can be engaged with the hook 4.

えるようになっている。Since the ladder frame 3.3 is held so as to rotate together with the guide frame 6 of the holder 2, it can be folded and stored on the back side of the scaffold board 1 as shown in FIG. In order to fit the frames 3.3 overlapping each other, the holder 2 located on the left side of FIG. , it has a low bulk and can be folded smoothly.

斜地での使用も可能になる。The work scaffold of this invention has the above-mentioned configuration, and each ladder frame 3 is inserted and attached to the guide frame 6 of the holder 2 attached to both ends of the scaffold board 1, and the ladder frames 3 on both sides are attached together with the holder 2. When the treadle 3b is rotated upright and the treadle 3b at the desired position is engaged with the hook 4, the ladder frames 3 on both sides become the lower floor and both ends G of the scaffolding board 1 are fixed. It can stand on its own as shown in the figure, and can also be used on stepped floors or slopes, as shown in Figure 10.

また、収納や輸送時には、ホルダー２と梯子枠３を足場
板１の裏面側に折畳めばよく、第４図の如く足場板１と
両梯子枠３．３とが扁平に重なる。Further, when storing or transporting, the holder 2 and the ladder frame 3 may be folded to the back side of the scaffolding board 1, and the scaffolding board 1 and both ladder frames 3.3 overlap flatly as shown in FIG.

両側の梯子枠３．３は足場板１の高さを踏桟３ｂの間隔
で自由に調整でとると共に、ホルダー２から抜取れば梯
子として使用することができる。The ladder frames 3.3 on both sides allow the height of the scaffolding board 1 to be freely adjusted by adjusting the spacing between the rungs 3b, and can be used as a ladder when removed from the holder 2.

以上のように、この発明によると上記のような構成であ
るので、以下に列挙する効果がある。As described above, since the present invention has the above configuration, it has the following effects.

（１）足場板の両端に取付けたホルダーで梯子枠を長手
方向に移動自在となるようＧこ保持し、梯子枠をホルダ
ーＧこよって、足場板の両端で起立する状態から足場板
の裏面に平行する折畳自在とし、足場板の端部に梯子枠
踏桟の掛止具を設けたので、両側の梯子枠を足場板の下
面Ｑこ折畳むことにより、全体を扁平にすることかでき
、収納や輸送が極めて至便になる。(1) Hold the ladder frame with holders attached to both ends of the scaffold board so that it can move freely in the longitudinal direction, and move the ladder frame from the holder G to the back side of the scaffold board from the state where it stands up on both ends of the scaffold board. Since the platform can be folded parallel to each other, and a hook for the ladder frame treadle is provided at the end of the scaffolding board, the entire structure can be made flat by folding the ladder frames on both sides along the bottom surface of the scaffolding board. This makes storage and transportation extremely convenient.

（２）梯子枠の踏桟を掛止具Ｏこ掛合して足場板と固定
化するので、足場板に対する梯子枠の結合が強固Ｇこな
り、作業が安全に行なえる。(2) Since the rungs of the ladder frame are fixed to the scaffolding board by engaging them with the hooks, the ladder frame is firmly connected to the scaffolding board, allowing work to be carried out safely.

（３）ホルダーに対して梯子枠をフライ１ζ自在とした
ので、作業条件に応じて足場板の高さを踏桟の間隔で自
由Ｑこ調整することができる。(3) Since the ladder frame is freely movable with respect to the holder, the height of the scaffolding board can be freely adjusted by the distance between the treads according to the work conditions.

（４）ホルダー〇二対して梯子枠が着脱自在であるので
、梯子枠を梯子として単独使用できる。(4) Since the ladder frame is detachable from the holder 〇2, the ladder frame can be used alone as a ladder.

（５）梯子枠と足場板は分離可能であるため、相互に長
さの異なるものを用意し、作業条件Ｑこ応じて必要なも
のを選択すれば、高さや長さの異なるものを自由に組立
てることができ、梯子枠と足場板Ｏこ互換性をもたせる
ことができる。(5) Since the ladder frame and scaffolding board can be separated, you can freely use different heights and lengths by preparing ones with different lengths and selecting the necessary one according to the working conditions. It can be assembled and the ladder frame and scaffolding board can be interchanged.

（６）両梯子枠の足場板との結合位置を自由に選択でき
るので、段のついた床や傾斜地Ｇこおいても使用するこ
とができる。(6) Since the joining position of both ladder frames to the scaffolding board can be freely selected, it can be used even on stepped floors and slopes.
