Description

[Technical Field]

[0001] The present invention relates to a temporary scaffolding device, and more particularly to a temporary scaffolding device that is installed at the corners of a building. [Background technology]

[0002] Conventionally, a scaffolding unit has been proposed as a temporary scaffolding, for example, comprising at least four or more vertically arranged base rods, an appropriate number of horizontal members connecting these base rods in pairs, at least two or more baseboards arranged horizontally opposite each other to form an erect scaffolding frame by connecting the paired base rods, and an appropriate number of scaffolding boards arranged and attached between the opposing baseboards (Patent Document 1).

[0004] In addition, most of the temporary scaffolding provided up until now has been rectangular in shape and has a structure that is installed along the vertical wall of a building. Therefore, when forming scaffolding at the corner of a building, the ends of rectangular scaffolding 1, 1a are crossed at right angles to close the corner, as shown in Figure 9. In the figure, 20 is the building, and 21 is the pillar of building 20. However, preparing and installing scaffolding boards of different sizes was time-consuming.

[0005] Furthermore, as mentioned above, instead of crossing the ends of the scaffolding boards at right angles, boards or other materials were placed across the gaps at the corners of the building to fill them and allow workers to walk on them. However, this did not ensure the safety of the workers and required a lot of work to set up the scaffolding. Summary of the Invention [Problem to be solved by the invention]

[0006] In view of the above circumstances, the present invention aims to provide a temporary scaffolding device that makes it easy to set up scaffolding at corners of buildings and ensures the safety and security of workers. [Means for solving the problem]

[0007] The temporary scaffolding device of the present invention, which solves the above-mentioned problems, is a scaffolding that is approximately a right-angled triangle in plan view, having a right angle portion and two acute angle portions, and is characterized in that support posts are placed at each corner, and scaffolding boards are provided at intervals above and below the interior of the support posts (Claim 1).

[0008] According to the present invention, continuous scaffolding can be easily installed around a building without changing the installation method of conventional rectangular scaffolding. That is, by inserting the temporary scaffolding device of the present invention into the gaps in the corners formed by the conventional rectangular scaffolding and integrating the support columns of the conventional scaffolding installed on both sides with the support columns of the scaffolding device of the present invention using connecting and fixing members, continuous scaffolding can be easily installed around a building. Moreover, the safety and security of workers can be ensured.

[0009] One embodiment of the present invention is characterized in that two support columns are arranged parallel to the right angle portion (claim 2). According to this embodiment, the work of connecting the scaffolding devices on both sides can be carried out easily and evenly.

[0010] One embodiment of the present invention is characterized in that baseboards are provided at the scaffolding board positions between support posts arranged at acute angles (claim 3). This embodiment prevents workers from accidentally losing their feet from the scaffolding boards when turning at right angles, and also prevents working tools and the like from falling.

[0011] One embodiment of the present invention is characterized in that handrails are provided between the upper and lower scaffolding boards between the support posts arranged at acute angles (claim 4). This embodiment ensures safety and security for workers when they change direction at right angles. [Effects of the Invention]

[0012] According to the present invention, it is easy to set up scaffolding at the corners of buildings, and the safety and security of workers can be ensured. [Brief explanation of the drawings]
