Description

[Detailed description of the invention] This invention relates to a movable scaffold that allows work to be carried out safely at heights, mainly when assembling ridge top girders, main buildings, etc. in wooden buildings.

In wooden buildings, when building columns and installing girders and beams on top of them, workers stand on top of the beams and use brackets to ensure that the girders and beams fit together accurately. However, the work using these racks is dangerous and involves unstable work at heights, such as when constructing a building.

This invention was made to make work at such heights safer and to allow easy movement at heights.Next, the structure, operation, and effects of this invention will be explained.

The movable scaffold of the present invention is constructed so that it can be placed astride horizontally or nearly horizontally arranged beams or girders in wooden buildings, lightweight steel buildings, etc.

The movable scaffold of this invention consists of two scaffold members A and B formed in the same shape along the side surface of a support member H such as a beam, which can be assembled and disassembled into one body using a connector.

Scaffold members A and B have the same shape and are opposed to each other, so
To describe only one of them, there are two vertical rods 1.1 along the sides of the beam, which are large enough to safely accommodate one worker on the mobile scaffold; It consists of a connecting rod 2 whose upper ends are connected almost horizontally, and a footrest 3 which is foldably supported by a shaft 4 at the lower end of the vertical rods 1 and 1.

The vertical rods 1, 1 and the connecting rod 2 are integrally welded together, and the footrest 3 swings from a position substantially parallel to the vertical rod to a position perpendicular to the vertical rod via a shaft 4, and is provided in a foldable manner. ,
When the footrest is opened, it protrudes approximately horizontally outward from the vertical rod, making it convenient for placing feet on it.

Moving wheels 5 are protruded from the lower surface of the connecting rod 2, so that when the moving scaffold is straddled over a beam, etc., the wheels are placed on the upper surface of the beam and the scaffold can be moved by rolling on the upper surface of the beam. Eggplant.

In this way, the two scaffolding members A are formed into the same shape.

B is connected via a connecting tool 6 made of a square pipe material, a round pipe material, etc. similar to a vertical rod, a connecting rod, etc.

One or two connectors 6 slightly longer than the width of the beam are installed between two opposing scaffolding members A and B.

This is done using a connector holder 7 that projects from the top of both scaffolding members.

The connector 6 is inserted into the connector holder 7, and the width of the connector 6 is set so that the beam H can be held between the opposing scaffold members A and B when the movable scaffold is straddled over the beam. Fixed to.

This can be easily done using the set bolt 8 provided on the holding device.

If the connector 6 is detachable from the holder of the scaffolding member, the scaffolding member can be disassembled to reduce its bulk when not in use or when being carried.

To work using this mobile scaffolding, first place the scaffolding over a beam, etc., and work while sitting astride the scaffolding. You can also stand up and work.

Therefore, this mobile scaffolding is unstable and allows for safe work at high places, and it is also easy to carry as it is prefabricated.
Furthermore, even when working at a different location on the same beam, the wheels can be used to easily and safely move the workpiece to the desired location, which is a practical idea with many practical effects.
