Description

[Detailed description of the invention] This invention relates to a movable scaffold that allows the work floor to be adjusted.

As shown in Figure ₁ , conventionally used mobile scaffolding has a space A ₁ that allows workers to pass through in the horizontal direction _.
The work floor was placed on top of the floor, and the height could not be adjusted, making it impossible to work efficiently. Therefore, when adjusting the height, it was necessary to change the position appropriately by using special metal fittings or by assembling using appropriate pipes.

However, such a device has drawbacks such as its assembly and disassembly is troublesome and takes many man-hours, and its position is not fixed, making it unstable and potentially impairing work safety.

This invention eliminates the above-mentioned drawbacks, makes it easy to adjust the height of the work floor, and because the installation position is a fixed part, the work can be done safely without danger, and it is suitable for ceiling work, etc., which allows workers to pass through. Our goal is to provide mobile scaffolding.

The structure of this invention to achieve the above-mentioned object is such that there is a space between the vertical main supports on both sides of the frame formed by the vertical main supports on both sides and the upper and lower horizontal frame members, so that a worker can pass through the space 2. One of the vertical sub-posts of the book should be placed at the end of the horizontal frame near one of the main vertical posts, and the other sub-vertical sub-post should be placed closer to the main vertical post from the center of the horizontal frame. When two work floors are lined up with their longitudinal edges touching on multiple work floor support horizontal members installed in lopsided positions and installed between the vertical main strut and the vertical sub-strut, the width of each work floor Attach the vertical sub-pillars to the upper and lower horizontal frames and multiple work floor support horizontal members at intervals that allow each latch provided in the direction to be locked, creating two building frames, and connect these frames with the horizontal frames. It consists of connected movable scaffolds.

Hereinafter, embodiments of this invention will be described based on the drawings.

In Figure 2, reference numeral 1 denotes a building frame, which is formed by vertical main supports 2a, 2b on both the left and right sides and upper and lower horizontal frames 3a, 3b, and workers can pass through between the upper and lower horizontal frames 3a, 3b. Vertical sub-pillars 5a and 5b are installed on the left and right with an interval of 4. In this case, in FIG. 2, the left vertical sub-support strut 5a is
At a position near one of the vertical main columns 2a at the end of b, a right vertical sub-branch 5b is provided in a position biased toward the left vertical main column 2a from the center of the upper and lower horizontal frames 3a, 3b, Between the left vertical main column 2a and the left vertical sub-column 5a, and between the right vertical main column 2b and the right vertical sub-column 5b
Between the upper horizontal frame member 3a and the lower horizontal frame member 3b
In between, in FIG. 3, the work floor support cross members 6a, 7
a, 8a and work floor support cross members 6b, 7b, 8b
is installed.

The 12 frames formed in this way are placed in the third
As shown in the figure, connect with horizontal frame 9, and use braces 10 as appropriate.
to form a mobile scaffold.

The work floor 11 includes a horizontal frame member 3a and a work floor support horizontal member 6.
The position can be adjusted up or down by engaging any one of a, 6b, 7a, 7b, 8a, and 8b. In this rehanging, the latch 12 can be removed by simply lifting the work floor 11, and after raising or lowering it to the required position, it can be reliably hooked to the cross frame or work floor support cross member by simply lowering it down. can be installed. 13 is a wheel, and 14 is a handrail.

Because this device has the above-mentioned configuration, even though it is a mobile scaffold that workers can pass through laterally, it creates a wide work area with two work floors lined up on the top of the scaffold. A work floor that allows you to secure a convenient space for working in large areas such as can be adjusted to the vertical position, improving work efficiency.Moreover, this adjustment does not require the use of special fittings or troublesome work such as assembling pipes, and can be adjusted easily on the work floor. This can be easily done by simply lifting the work floor support member upward, then lowering it onto the work floor support cross member at an appropriate height, and locking the latch. The horizontal members are attached to the vertical main column and the vertical sub-column, and their positions are fixed, so they are stable, and the work floor can be adjusted safely. This has the effect of greatly increasing the utility value of the work.

Claims (1)

[Scope of utility model registration request] Vertical main struts 2a and 2b on both sides and upper and lower horizontal frames 3
A worker can pass through the space 4 between the vertical main supports 2a and 2b on both sides of the frame body formed by the frame body formed by the frame members 5a and 3b. At the end of the frame members 3a, 3b, near one vertical main strut 2a, and the other vertical sub-strut 5b.
is provided at a position that is biased toward one vertical main support 2a side from the center of the horizontal frame members 3a, 3b, and the vertical main support 2a, 2b
When two work floors 11 are arranged with their longitudinal edges touching each other on a plurality of work floor support horizontal members 6a, 6b, 7a, 7b provided between the vertical sub-pillars 5a, 5b, each work floor The vertical sub-pillars 5a, 5b are connected to the upper and lower horizontal frame members 3a, 3b and a plurality of work floor support horizontal members 6a, 6b, 7a, 7b at intervals such that each latch 12 provided in the width direction of the frame 11 can be locked. This is a mobile scaffolding that is attached to the frame to form two building frames 1 and 1, and these building frames 1 and 1 are connected by horizontal frames 9 and 9.
