Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a stepping plate support pillar, and more particularly to a scaffolding plate support pillar used to support the scaffolding board, which is formed by passing the scaffolding board between the stepladders.

[0002]

[Prior art]

 The stepladder scaffold made by passing the scaffolding board between the stepladders is used as a so-called temporary scaffolding for work such as indoor walls and ceilings. That is, as an example of the stepping scaffolding, as shown in FIG. 3, the scaffolding plate 6 is passed to the third steps 7a, 7a of the steppings 7, 7 to make a simple temporary scaffolding 8, and It is used when the worker 10 works on a wall, a ceiling or the like inside the riding room. However, when using the stepladder scaffolding, it is regulated to support the scaffolding board at three points or to use two scaffolding boards in order to ensure the safety of work.

[0003]

[Problems to be solved by the device]

 As mentioned above, when using a stepping scaffold in construction work, etc., it is obligatory to support the scaffolding board at three points or to use two scaffolding boards in layers, but in practice this regulation is observed. The current situation is not.

The reason is that it is troublesome to install a stepladder in the middle of one scaffolding board or to set two scaffolding boards in the field work. Is a simple temporary scaffold, so there is no danger of height, there is no fear of breaking because it is a steel scaffolding board, and lateral movement is inconvenient if three points are supported. Therefore, the above regulations are not observed. However, when the load on the scaffolding plate is large, there is a risk that the scaffolding plate bends, the scaffolding plate breaks, or the worker shakes on the scaffolding plate and falls.

The present invention has been made in view of the current situation in which regulations such as three-point support of scaffolding boards passed between stepladders are not observed and the problems thereof, and the purpose thereof is to bend or break the scaffolding board. It is an object of the present invention to provide a stepping plate support pillar that can be easily carried and moved, and can be easily attached.

[0006]

[Means and Actions for Solving the Problems]

 The present inventor made various studies on the solution to the above-mentioned problems, and paid attention to a supporting column composed of a U-shaped metal object and a column body for sandwiching the scaffolding plate as a column supporting the scaffolding plate passed between the stepladders. .

The present invention is based on the above idea, and the gist thereof is a step for supporting a scaffold plate in a stepladder scaffold formed by passing a scaffold plate between the stepladder. A stepping scaffolding board support strut characterized by connecting a U-shaped metal object for sandwiching the board and a pillar body provided with a substrate at one end,

In a stepladder scaffold formed by passing a scaffolding board between stepladders, a pillar for supporting the scaffolding board, a U-shaped metal object for sandwiching the scaffolding board and a substrate provided at one end Are connected via a height adjusting tool.

The stepping scaffold in the present invention is mainly used for interior finishing, but is not limited to this. Further, as the stepladder, those made of steel pipe or aluminum alloy are generally used. Further, the scaffolding board to be passed between the stepladders is mainly made of steel.

The stepping scaffolding plate supporting column according to the present invention supports a scaffolding plate in a state in which two points are supported by the above-mentioned two legs of the scaffolding plate, for example, an intermediate point of the scaffolding plate. The structure is composed of a U-shaped metal object for sandwiching and supporting the scaffolding plate and a columnar body having a substrate provided at one end. Further, the stepping plate support pillar according to the present invention has a structure in which a U-shaped metal object for sandwiching the scaffold plate and a column body having a substrate provided at one end are connected through a height adjusting tool, thereby making It is convenient to use in practice. An example of this height adjuster is a bolt provided below the U-shaped metal piece and a nut provided at the other end of a column body having a substrate at one end. Can be raised.

【Example】

 The present invention will be described below based on examples. The stepladder scaffold is used as a so-called temporary scaffold for work such as indoor walls and ceilings, but it is made by passing a scaffold board between the stepladder and the stepladder, and generally, the above-mentioned figure. As shown in FIG. However, when using the stepladder scaffolding, it is regulated to support the scaffolding board at three points or to use two scaffolding boards in order to ensure the safety of work.

When supporting three points of the scaffolding board when using the stepping scaffold, the scaffolding board 6 is passed to the third step 7a, 7a of each of the stepladders 7, 7 shown in FIG. In the field work, one more stepladder is installed at the intermediate point 6a of the scaffolding plate 6 to support the scaffolding plate, or as shown in FIG. There is a method of mounting and supporting.

In view of this, the present invention has a structure in which a U-shaped metal member for sandwiching a scaffolding plate and a columnar body having a substrate provided at one end are coupled via a height adjuster as shown in FIG. 1 (1). Present the stepping plate support pillars. That is, FIG. 1 (1) shows a stepping scaffolding plate supporting column 1 in which a U-shaped metal fitting 2 for sandwiching a scaffolding plate 6 and a columnar body 4 having a substrate 3 at one end are connected via a height adjusting tool 5. It is shown. The height adjusting tool 5 is composed of a bolt 5b provided below the U-shaped metal fitting 2 via a support frame 5a, and a nut 5c provided at the other end of the pillar 4 having the substrate 3 provided at one end. It is a thing.

Further, FIG. 1 (2) is a perspective view of a stepping scaffolding board supporting column 1 according to the present invention. In the figure, 2 is a U-shaped metal object for sandwiching the scaffolding board, and 4 is a substrate 3 provided at one end. The U-shaped metal fitting 2 and the above-mentioned pillar 4 are joined together via a height adjuster 5 to form a stepladder scaffolding board support pillar 1.

[0015]

[Effect of device]

 The present invention relates to a pillar for supporting a scaffolding board, which is formed by passing a scaffolding board between the stepladders, and is provided with a U-shaped metal object for sandwiching the scaffolding board and a board at one end. It is a stepping scaffolding board supporting strut with a structure in which pillars are connected and a stepping scaffolding board supporting strut that can adjust the height at which the scaffolding board is clamped. Therefore, it is possible to prevent the scaffolding plate from bending or breaking, easy to carry and move, and easy to attach in a two-point supporting state. Furthermore, since it is easy to adjust the support height and position of the scaffolding plate, it is easy to use at the work site and it is possible to easily comply with the regulation of three-point support.
