Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This invention relates to a simple folding scaffolding suitable for high-altitude work in on-site construction.

0002

[Conventional technology]

Traditionally, scaffolding for on-site construction was constructed using logs as shown in Figure 4, or as shown in Figure 5. Scaffolding is assembled using steel pipes, but in this case, the pillars 01, the width beams 02, and the length The brace 04 that intersects with the longitudinal beam 03 is all a single item, and these separate pieces are in the order of column 01 → width direction beam 02 → length direction beam 03 → brace 04. It was assembled in sequence.

0003

[Problem that the idea aims to solve]

However, when assembling scaffolding on-site, there are many components, and when transporting the components, Not only does it require a lot of manpower, but it also takes time to assemble, and the assembly requires work at heights. There were problems such as being dangerous. This invention was developed to deal with such problems, and the scaffolding can be folded freely. The purpose is to assemble.

0004

[Means to solve the problem]

1 to 3, which correspond to embodiments of the configuration of the present invention to achieve the above object, are shown in FIGS. To explain using this, the present invention connects a plurality of columns 2 and the columns 2 so as to be foldable in the width direction. The plurality of width direction beams 3 and the support columns 2 are connected vertically in parallel so as to be freely foldable in the length direction. The bi-fold longitudinal beam 4 to be connected and the pillar 2 are intersected in the length direction and are foldable upwardly. It consists of a two-fold frame 6 with a turnbuckle 5 that intersects and connects to the bottom.

[0005]

[Effect]

According to the above-mentioned means of the present invention, the support in the width direction is supported in the width direction by the beam in the width direction. The longitudinal support is folded longitudinally by the longitudinal beam and the frame. The entire structure can be folded compactly into a bundle of columns for easy transportation and storage. Ru.

【Example】

An embodiment of the present invention will be described below based on FIGS. 1 to 3. 1 indicates a scaffold; The scaffold 1 has a plurality of columns 2 and a plurality of widths that connect the columns 2 so as to be foldable in the width direction. A bi-fold length that connects the direction beam 3 and the support column 2 in a vertically parallel manner so as to be freely foldable in the length direction. A tab that connects the transverse beam 4 and the support column 2 by vertically intersecting each other so as to be freely foldable in the length direction. It consists of a bi-fold brace 6 with a ring buckle 5, and in the illustrated one, the scaffold 1 is There are three pillars 2 on both the left and right sides, and these three pillars have pin joints at both ends. Scaffolding boards 7 are installed on the left and right sides of the width direction beam 3 as shown in FIG. I made it possible to lock it.

[0007] Thus, the scaffold 1 can be constructed at a single point in FIG. 1 by folding the longitudinal beams 4 and the braces 6. It is folded in the length direction as shown by the chain line, and the width direction beams 3 are further folded on both left and right sides. As a result, it is folded in the width direction as shown by the dashed line in Figure 2, and these folded supports form a bundle. It can be summarized as follows. In addition, when using it, transport the bundled pillars to the place where they will be used and place them on the floor. First, expand the longitudinal beams 4 that connect the columns 1 on both the left and right sides in the longitudinal direction to increase the length of the scaffold. Next, the width direction beams 3 that connect the columns 1 on both left and right sides in the width direction are widened. to form the width direction of the scaffold. In this state, the brakes protrude and connect to the four corner pillars. Expand the braces 6 and tighten the braces 6 using turnbuckles 5, then use the separately prepared scaffolding. A scaffold 1 is formed by fitting the plate 7 between the width direction beams 3.

[0008] Finally, connect the walls of nearby structures to stabilize them. Also, there is no one to connect to the wall. If this is not possible, attach the ends of the wire to the lugs attached to the top of the pillars at the four corners and attach them to nearby supports. to support.

[0009]

[Effect of the idea] In this way, according to the present invention, a plurality of columns are connected to each other so that the columns can be freely folded in the width direction. The multiple width direction beams connected to each other and the pillars are connected vertically in parallel so that they can be freely folded in the length direction. The bi-folded longitudinal beam and the pillar are vertically foldable and intersect vertically between them. The scaffold consists of bi-folded braces with 5 connecting turnbuckles. As a result, it is easier to assemble and dismantle the scaffolding, which simplifies the construction of the scaffolding. has.
