For example, JP-A-11-30043 or JP-A-2
The one disclosed in Japanese Patent Publication No. 000-34838 is known. In the case of Japanese Patent Laid-Open No. 11-30043, as shown in FIG. 9 (a), the main rope 40 is provided on the upper portion of the sandwiching portion 42 made of a clamp that is detachably fixed to the beam upper flange 41 and the like. Is a master rope strut 46 of a type in which the strut 43 having the locking ring portion of is firmly fixed in an inclined state,
Further, in the case of JP 2000-34838 A, FIG.
As shown in (b), the reinforcing core metal fitting 44 is attached from above in the lateral direction to the upper portion of the sandwiching portion 42 made of a clamp that is detachably fixed to the beam upper flange 41 and the like, and the supporting pillar 43 in the inclined state is attached. It is a master rope column 46 of a type that is detachably and firmly fixed by bolts and nuts 45.

があった。In any of the above-mentioned conventional cases, the support column 43 is a fixed type in which the position cannot be adjusted when the support column portion is attached to the sandwiching portion (clamp portion) 42. In the case where the width of the steel beam flange is narrow, the main rope columns 46 are symmetrically attached to both ends of the steel beam upper flange 41 in the left-right direction (width direction) according to the widthwise dimension of the scaffold on the beam flange 41 or the like. In the case where the main rope support column spacing is narrow, or the steel beam flange width is wide, the parent rope support spacing becomes wide, and it is difficult to make the width of the top of the support pillar easy to work. There is a problem that it is necessary to separately prepare a large number of main rope columns 46 having columns 43 having an appropriate vertical state or an inclination angle corresponding to the flange width dimension to accommodate the steel beam flange width.

することができる。In the above-described embodiment, the horizontal shaft 29 which is a stepped bolt having the small diameter male screw shaft portions 26 at both ends is used.
Although a slip-out preventing member composed of a nut 49 is screwed on both ends and the nut serves as a loosening prevention means by a set screw 47, when the present invention is carried out, the horizontal shaft 29 is
You may use the horizontal shaft 29 which consists of a pin or a bolt which has a diameter expansion head at one end. Further, when implementing the present invention, one or two openings that are slightly larger than the L-shaped cross-sectional shape of the ratchet member 13 are provided at symmetrical positions on either or both of the front wall 3 and the rear wall 4. The cover plate or rattling member 1 is provided so that these openings serve as openings for inserting or removing the rattling member 13 and that the opening is closed.
When the cover plate with 3 is detachably provided on the front wall 3 or the rear wall 4 by bolting or the like, the horizontal shaft 29, the tilt adjusting metal fitting 14, and the support post 34 are not removed.
Simply remove the lid plate and the ratchet stop member 13,
The column 34 can be held in the vertical state or the inclined state only by rotating the tilt adjusting metal fitting 14 to which is attached about the horizontal axis 29 and simply attaching the rattling stop member 13 from the other opening. .

垂直状態から傾斜状態への分解組み立てが容易である。According to the main rope with adjustable tilt according to claim 1 or 2 of the present invention, depending on the width of the beam flange of a steel frame or the like, the pillar is erected vertically or spreads outward. Since the worker can stand upright, the worker can walk easily and workability is improved. Further, since one master rope support column whose tilt can be adjusted can be installed in correspondence with the width of a plurality of steel beam flanges, etc., it is an economical master rope support pillar whose tilt can be adjusted. Further, the rattling member is arranged in the upward opening concave portion of the sandwiching metal fitting, so that the tilt adjusting metal fitting can be easily prevented from rotating and the pillar can be held in a stable state, and it is not necessary to remove it. The tilt adjustment metal fittings can be pivoted to the sandwich metal fittings by a horizontal axis or a detachable horizontal axis, or have a simple structure that is detachable. ,
The disassembly and assembly from the vertical state to the inclined state is easy.
