Description

[Detailed description of the invention] [Technical field] The present invention has a movable leg piece at one end that can be flipped up and down and into which a building horizontal member can be inserted, and is particularly suitable for attaching a scaffolding board across the atrium of a building. Regarding scaffolding that can be used for

[Background technology]

In cases such as finishing walls surrounding the atrium of a building, stepladder-like scaffolding that rises from the floor below or a ladder has traditionally been used, but these are less stable and cannot be handled from the scaffolding. The range was small and it had to be moved frequently, resulting in poor work efficiency.

[Purpose of invention]

The present invention has a long base material, and at one end thereof,
By providing movable leg pieces to which building horizontal members can be attached, scaffolding boards can be stably and easily attached to large spaces such as atriums, and large areas can be treated. It is intended to provide scaffolding.

[Disclosure of invention]

An embodiment of the present invention will be described below based on the drawings.

In the figure, a scaffold 1 of the present invention includes a pair of scaffold frames 2, 2, and a scaffold board 3 spanning between them. The scaffolding frame 2 has one end of a long rectangular cylindrical base material 5 bent, and downwardly facing leg pieces 6 having a base plate 13 at the lower end hanging down. The character piece 14 is fixed. A movable leg piece 7 is pivotally supported at the other end of the base member 5. The movable leg piece 7 has a projecting piece fitted into a groove formed at the other end of the base material 5 and is supported pivotably. In the vertically inverted state of the leg piece 7, the receiving surfaces 15 on both sides of the protruding piece are aligned with the upper and lower surfaces 16 of the base material 5,
16 in its perpendicular state, so that the movable leg piece 7 is vertically inverted and perpendicular to the base member 5 in the inverted state. Furthermore, the movable leg piece 7 has the same length as the leg piece 6, and has a shape at its tip when it is flipped up.
The upper end of the wall panel P, etc. that rises near the other end,
A U-shaped locking portion 11 having a width that allows the horizontal building member 9 to be inserted and opening inward is provided. Note that the building horizontal member 9 is the wall panel P described above.
When , the lengths of the leg piece 6 and the movable leg piece 7 are
By setting the height to approximately half the height of the wall panel P and fitting the locking portion 11 to the building horizontal member 9, the base material 5 is held horizontally.

The scaffolding board 3 has a top board 20 attached to a rectangular frame 19, a non-slip board 21 on the top surface, and hanging pieces 22, 22 on the bottom end that sandwich the base material 5.
By lowering the base material 5 on both sides and in the front and back,
It can be installed on the upper surface of the scaffolding frame 2, and can be installed across the scaffolding frame 2.

However, as shown in FIG. 3, when a floor plate F is placed on one side and a wall panel P is placed on the other side with the atrium a in between, the movable leg piece 7 is flipped up and the locking part 11 is used to lock the wall panel P. By attaching the leg pieces 6 to the upper end, installing the leg pieces 6 on the floorboard F, and attaching the scaffolding board 3, the scaffolding board 3 can be spanned across the atrium a. Note that the L-shaped piece 14 of the leg piece 6 has the following:
A hanging scroll 24 is fitted into a recess 25 provided on the lower surface to reinforce the leg piece 6. Furthermore, as shown in Figure 4, the floor plate F
When a well-through portion a is provided in the center of the space, the movable leg piece 7 can be bent downward to cross the well-through portion a.

[Effect of the invention] As described above, the scaffold of the present invention has a leg piece at one end and a reversible movable leg piece at the other end, so it can be used as a normal scaffold by bending the movable leg piece downward. It can also be attached to horizontal building members located at high places by flipping up, expanding the scope of use, and since the base material of the scaffolding frame is long, it can be used in relatively large spaces such as the atrium of a building. The boards can be spanned, and the scaffolding boards can be used to perform scaffolding work over a wide area. The scaffolding of this invention is
It can be suitably used in various places where one leg cannot be installed, such as an atrium or a staircase landing.
