[Detailed description of the invention]

[0001]

[Industrial Application Field] The present invention is to diagonally move a temporary scaffold from a temporary scaffold onto a road to protect work materials and tools from directly falling on the road when the temporary scaffold is adjacent to the road. The present invention relates to a bosh apparatus that is erected upward, and particularly to a foldable bosh apparatus that can be folded along a temporary scaffold.

[0002]

2. Description of the Related Art A conventional bosh apparatus has been assembled using versatile clamp fittings, pipe materials, panel materials, and the like. In addition, there was a problem that the demolition work was dangerous.

Therefore, as disclosed in, for example, Japanese Patent Publication No. 4-54788 and Japanese Patent Publication No. 4-72023, it is possible to fold the morning glory device from a position protruding on the road to a position along a temporary scaffold. A folding type morning glory device has been proposed. In other words, Japanese Patent Publication No. 4-54788 discloses a diagonal member that supports the base end of a bosh device so as to be rotatable in the vertical direction, and that is capable of extending and contracting the bosh device and fixing it in an extended state and a contracted state. There is disclosed an apparatus which is supported from below, and in which the bosh device is in a folded state when the oblique member is in an extended state and is in an extended state in a shortened state.
Further, Japanese Patent Publication No. 4-72023 discloses that a base end of a bosh apparatus is supported rotatably in a vertical direction, and the bosh apparatus is supported by a hanging member having an joint, and the hanging member is bent at a joint position. There is disclosed an apparatus in which a folded state is obtained by causing the apparatus to be folded.

[0004]

However, in Japanese Patent Publication No. 4-54788, since the oblique member is folded when fully extended, the length of the oblique member is fixed. It can be performed at a position close to the temporary scaffold, and when completely shortened, it can be fixed at a position close to the temporary scaffold at the base end of the diagonal member, so that work can be performed without danger. When fixing the device by changing its inclination angle, it is necessary to perform the fixing operation of the oblique member at a position away from the temporary scaffolding, and there is a problem that the operation involves danger. A similar problem occurs when the distance between the base end of the bosh apparatus and the base end of the oblique member or the connection position between the bosh apparatus and the oblique member changes.

On the other hand, in Japanese Patent Publication No. 4-72023, there is a problem that it is impossible to fix the bosh apparatus by changing its inclination angle unless it is changed to hanging members having different lengths. Further, since the hanging member is located on the bosh apparatus, there is a problem that a falling object may hit the hanging member, jump over the bosh apparatus and fall to the ground.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, an object of the present invention is to propose a folding bosh apparatus which can always work safely even when the bosh apparatus is fixed at different inclination angles. .

In order to achieve the above-mentioned object, the present invention provides a method according to the present invention, in which one or more pairs of main members 3, 3 are provided with a temporary scaffold 2 as shown in FIG. And a front end and a base end of the main member 3 are connected to each other by a front end connection member 4 and a base end connection member 5, respectively, to form a frame. And a guide portion 17 extending in the vertical direction corresponding to each main member 3 is attached to a position at an appropriate distance in the vertical direction from the mounting position of the main member 3 of the temporary scaffold 2, and the oblique member is attached to the main member 3. One end of the oblique member 15 is rotatably connected, and the other end of the oblique member 15 is movably supported in the longitudinal direction by a guide portion 17 and a fixing means 25 for fixing the guide portion 17 at a predetermined position is provided. Is adopted.

[0008]

In the present invention, the main member 3 is attached to the temporary scaffold 2 so as to be vertically rotatable. 15, connecting the distal end connecting member 4 and the proximal end connecting member 5 to form a frame, arranging the panel 6 in the frame, and mounting the guide portion 17, all of the assembly work of the morning glory apparatus 1 is temporarily performed. It can be performed easily and safely at a position close to the scaffold 2.

Further, when the morning glory device 1 is extended and fixed, when the main member 3 is suspended by a rope or the like and turned downward, the other end of the oblique member 15 is accordingly connected to the guide portion 17.
, The other end of the oblique member 15 may be fixed to the guide portion 17 by the fixing means 25 at a position where the bosh apparatus 1 is in a desired inclined state. In the case where the main member 3 is fixed with the guide member 17 or the distance between the base end of the main member 3 and the mounting position of the guide portion 17 or the connection position between the main member 3 and the oblique member 15 is changed, the fixing operation of the oblique member 15 is always performed. It can be performed on the guide portion 17 and can be safely and easily performed at a position close to the temporary scaffold 2.

The oblique member 15 and the guide portion 17 may be disposed above or below the main member 3. However, if disposed below, the falling object hits the oblique member 15 and the morning glory device is operated. The risk of jumping and falling to the ground can be eliminated.
