Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a mobile scaffold in which a longitudinal direction of a scaffold rail is a non-linear shape such as a linear shape and a curved shape.

[0002]

[Prior art]

 Conventionally, as this type of mobile scaffolding, a mobile scaffolding in which the longitudinal direction of the scaffolding rail is linear is known.

[0003]

[Problems to be solved by the device]

 If the construction site continuously changes to a straight line, the scaffolding that has been used in the past can be used to continuously perform construction using a mobile scaffolding whose longitudinal direction is linear. However, there is a problem that the construction cannot be carried out using the mobile scaffolding when the construction continuously changes to a non-linear shape such as a curved shape.

The present invention has been made in view of the above problems of the prior art, and the purpose thereof is not to mention the case where the construction site continuously changes to a straight line shape, It is intended to provide a mobile suspension scaffolding that can be used even when the construction site continuously changes to a non-linear shape such as a curved shape.

The traveling device mounting base 5D is attached to the lower portions of the pair of traveling machines 5A. The control box 5B is attached to the traveling device attachment base 5D. The scaffolding beam suspension fitting 11 is attached to the traveling device mounting base 5D. The guardian 2 can be attached so as to surround the work floor 3. A winch 9 is arranged inside the scaffolding beam 4.

A method of assembling the mobile suspension scaffold will be described. In an existing steel girder (or similar), a plurality of upper suspension fittings 6 are attached to the lower part of the planned construction site by welding or the like. Hang one end of the chain block 8 on the upper suspension metal fitting 6. A plurality of scaffolding beams 4 are transported on the ground where the construction is planned, and the scaffolding beams 4 are arranged parallel to each other. The work floor 3 is transported onto the scaffolding beam 4. The work floor 3 is fixed to the scaffold beam 4. Carry protective worker 2. The guardian 2 is attached around the work floor 3. The scaffolding rail 1 is transported near the work floor 3.

The winch wire 10 wound around the winch 9 is pulled out, and the tip of the winch wire 10 is passed through the hook of the scaffold beam suspension fitting 11. The hook at one end of the chain block 8 has already been hung on the upper hanging metal fitting 6, but the hook at the other end of the chain block 8 hangs on the lower hanging metal fitting 7. The chain block 8 is rolled up, and the scaffolding rail 1 is horizontally suspended and fixed at a predetermined height to be fixed. Next, the tip of the winch wire 10 passed through the hook of the scaffold beam suspension fitting 11 is pulled to horizontally suspend the scaffold beam 4.

In this way, the conditions for starting construction are set.

A case where the protection work 2 and the work floor 3 are moved to the next adjacent construction site after the construction is completed will be described. The operating device 5C is operated to start the traveling machine 5A. Since a constant voltage is applied to the traveling machine 5A, the traveling machine 5A eventually reaches a steady speed. When the guardian 2 and the work floor 3 reach the bottom of the next adjacent construction site, the traveling machine 5A is stopped. Normally, a scaffolding rail 1 having a linear longitudinal direction is used, but if necessary, a scaffolding rail 1 having a non-linear longitudinal direction is used.

When disassembling the mobile suspension scaffold, the procedure is the reverse of the method for assembling the mobile suspension scaffold.
