The present invention relates to a scaffold, which is a temporary structure for working or transporting materials at high altitudes in a building construction, and more specifically, for industrial safety accidents of workers such as scaffolding and tile work working on the scaffold. Laminated scaffoldings which can be prevented and made easy to install, dismantle, handle and store.

In general, in order to build a high-rise building, scaffolding, which is a temporary structure made to work at high altitudes or to transport materials, must be installed, and the installation hypothesis is made by a scaffold who specializes in this.

A scaffold is usually a vertical scaffolding pillar, a horizontal lattice scaffold that cuts across the scaffold column, a base that holds the scaffold column, and a polygonal shape to prevent angular deformation of the scaffold column and scaffold strip. It is a swashing line that is placed horizontally between the scaffolds facing each other, and the scaffolding line which supports the scaffolding board horizontally, the scaffolding board which is a high scaffolding to work across this scaffolding line, and the upper and lower floors of the building. It consists of stairs which are long roads, and ramps which do not have a step as a deformation | transformation of this stairs.

Conventional such scaffolding should be installed by a scaffold who installs it professionally, and the installation hypothesis takes a lot of time to install the installation hypothesis, accordingly the installation cost was also high.

In addition, no separate safety facilities were provided, which resulted in the occurrence of industrial safety accidents.

Therefore, there is an urgent need for scaffolds that are easy to install, dismantle, handle and store these materials, and to prevent safety accidents.

Therefore, the purpose of the present invention can be easily installed and installed on the beam of the steel structure to be pulled up by the crane at the time of installation. The present invention provides a laminated folding scaffold that can be easily handled and stored, preventing industrial accidents.

Laminated folding scaffold according to the present invention to achieve the above object is a plurality of scaffolding plate for the operator to work, a safety guard detachably mounted to the scaffolding plate to ensure the safety of the operator, the stacking folded on the scaffolding plate It comprises a plurality of ladder scaffolding columns and ladders that allow the worker to climb up and down the building.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

That is, the present invention, as shown in Figures 1 to 4, the number of the height between each of the non-stepping boards 10 is detachably installed so that one or a plurality of safety guards 20 can be safely worked by the operator The ladder-type scaffolding column 30 is installed to have a height between the floors of the building, and each of the scaffolding plates 10 is connected to the ladder 40 so that each scaffolding plate 10 is sequentially stacked and folded.

Each of the scaffolding plate 10 is connected to the upper and lower ends of the ladder-type scaffold column 30 in the front and rear ends, and the guide rail to which the roll 42 of the ladder 40 is rotated and slipped. 12 is formed and the door 13 which rotates up and down at a predetermined position is provided.

In addition, a bolt hole 14 for fixing and fixing the upper end of the ladder 40 with the bolt 15 and the nut 16 is legendary in the door 13 portion of each scaffold scaffold 10. On one side or both ends of the scaffold 10, a male screw 22 formed in the support 21 of the safety guard 20 penetrates, and a through hole 17 for fastening and fastening with the nut 24 is installed.

The safety guard 20 has two pillars 21 having a male screw 22 formed at a lower end thereof, and a horizontal bar 23 having a "ㅁ" shape on the pillars 21 is bent into a flat "-" shape. .

The ladder scaffolding column 30 is the end of each ladder scaffolding column 30 is foldably connected by the connecting piece 31 and the bolt 32 and the ladder 32 each of the ladder scaffolding column (30). In order to prevent the flow and angular deformation of the scaffolding 33 and the brace 24 is fastened by the nut 35 is fastened.

The ladder 40 has a bolt hole 41 penetrated at the top and a rotatable roll 42 at the bottom.

The ladder 40 is fixedly rotatable by fastening with a nut 16 so that the upper end is penetrated by the bolt 15 through the bolt holes 14 and 41 of the scaffolding plate 10 and the ladder 40 as shown in FIG. 3. The lower end is fitted with the roll 42 of the ladder 40 into the guide rail 12 formed at the front and rear ends of each scaffolding plate 10 as shown in FIG.

In the drawings, reference numeral 51 is a hanger including a chain to install a laminated folding scaffold of the present invention on a beam of steel structure, and 52 is a hook of a crane.

According to the present invention, the safety guard 20 is mounted with the nut 24 through the male screw 22 of the support 21 through the through hole 17 of the scaffold 10 of the uppermost stage. Ladder-type scaffolding column (30) connected to the uppermost non-stepping plate (10) like a second tile by collecting the chain of the hanger (51) extending from the topmost stepping plate (10) to Let it spread out vertically from the upper part of.

Next, while fastening the scaffolding strip 33 and the brace 34 with the nut 35 to the bolt 32 at the end of the ladder-type scaffolding column 30, the uppermost scaffold 10 is gradually lifted. In the same state, the first degree is in the same state.

At this time, the roll 42 of the lower end of the ladder 40 is rotated and slipped and moved into the inside of the non-stepping board 10.

Next, the installation hypothesis is completed by mounting the hanger 51 firmly abolished to the beam of the steel structure when the installation is raised to a predetermined height. When the worker wants to go upstairs directly from the predetermined floor, he pushes the door 13 of the non-stepping board 10 in a state where the ladder 40 is raised to a certain height and goes up to the upper floor to close the door 13. You can do it afterwards.

In order to dismantle the laminated folding scaffolding of the present invention in this manner, the chains of the hanger 52 extending from the scaffolding plate 10 at the top of the hook 52 of the crane are collected and laid down on the ground. When the scaffold strip 33 and the brace 34 fastened to the bolt 32 at each end of each ladder-type scaffold column 30 are disassembled and removed, the ladder is connected to the lower scaffold 10 as shown in the second diagram. The type scaffolding pillar 30 is laminated and folded sequentially from the connecting piece 31 and the bolt 32 as a starting point.

At the same time, the roll 42 at the bottom of the ladder 40 rotates and slides out of the non-stepping board 10 in the guide rail 12 of the non-stepping board 10 so as to lie down in a horizontal state. Will be stacked.

Therefore, it is easy to install and dismantle the laminated folding scaffolding according to the present invention, as well as to easily handle them, and to store them in a yard or warehouse, and the worker by a plurality of ladder-type scaffolding pillars 30 and safety guards 20. It is possible to prevent industrial accidents.

As described above, the present invention provides a plurality of scaffolding plates 10 having detachable safety guards 20, and a plurality of ladder-type scaffolding pillars 30 and ladders that are stacked and folded on the scaffolding plate 10. By providing a laminated folding scaffold comprising 40, an operator can safely perform work at high altitudes in a construction work, and can easily prevent installation accidents, dismantle and store industrial safety accidents. It is a useful design.

In addition, there is an effect that the labor costs and material costs are reduced by the easy installation and dismantling.

Claims (1)

However, a plurality of ladder-type scaffolding columns 30 having an even height between each of the scaffolding plates 10 in which a plurality of safety guards 20 are detachably installed are connected to each other to have a height between floors of the building and each scaffolding plate ( Chuck layer folding scaffold, characterized in that 10) is installed in order to be laminated to the upper and lower scaffolding plate (10).
