Description

[Detailed Description of the Invention] [Industrial application] The present invention relates to a scaffolding device for stairs, and more particularly to a scaffolding device which is convenient for lower surface work such as an emergency staircase of a steel frame.

[Conventional technology]

Conventionally, in lower surface work of a steel frame emergency staircase or a steel frame staircase during construction, for example, rust prevention, finish painting work, etc., scaffolds have been assembled from a stairway portion under the staircase to a standing state using a large number of pipes and clamps. That is, since the installation surface is a staircase, it is difficult to use a pre-assembled running scaffold or the like.

[Problems to be solved by the device]

In the conventional scaffolding device, a large number of pipes and clamps must be prepared, and since the installation surface is a stair, it requires skill and labor for assembling, and dismantling also requires danger. There were problems such as being accompanied by.

Moreover, when handling the pipes during the assembly and disassembly, the stairs may be damaged. In addition, the pipes used as stanchions could pinch the work space and interfere with painting work.

The present invention has been made in view of the above circumstances, and simplifies the structure, facilitates handling such as transportation and storage, and does not require labor for installation and dismantling, which enables quick work and is economical. It is intended to provide a scaffolding device for stairs.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention provides a hook clamp that can be fixed to the upper part of a column, a rectangular vertical frame that can be fixed to the center part and that has a substantially stair width, and a lower part. And a locking clamp that can be fixed to the lower side stairs.

[Action]

The scaffold of the present invention is not assembled from the installation surface in a standing state, but is installed in a suspended state from one side of the stairs.

Therefore, it is possible to easily install and dismantle from one side of the stairs without being affected by the installation surface (stairs) as in the conventional case, and to improve work efficiency.

Further, unlike the prior art, it is not necessary to prepare a large number of pipes, clamps, etc., so that handling such as transportation and storage is easy and economical, and the working space is not narrowed.

〔Example〕

An embodiment of the present invention will be described below in detail with reference to the drawings.

The column (1) is composed of a pipe having an appropriate length, and a hook clamp (2) which can be fixed is provided on the upper portion. That is, the hook clamp (2) is fixed to the column (1) by the tightening screw (4) which constitutes the hook clamp (2).

Reference numeral (5) is a backing plate for stabilizing the hook clamp (2) and the column (1).

Further, a fixable rectangular vertical frame body (6) is provided at the center of the column (1).

That is, the rectangular vertical frame body (6) is fixed to the column (1) by the tightening screws (8) of the clamps (7) provided above and below one end of the rectangular vertical frame body (6).

The rectangular vertical frame body (6) has a length substantially equal to the width (W) of the stairs (S), and is literally a vertical frame body. That is, it has an upper bar (9) and a lower bar (10) which form a stepped scaffold.

Further, it is desirable that the vertical rods (11) provided at the tip ends of the upper rail (9) and the lower rail (10) are upper end open pipes.

As a result, the column (12) for constituting the handrail can be easily erected on the vertical rod (11).

Next, a fixing clamp (13) that can be fixed is provided on the lower portion of the column (1). That is, the locking clamp (13) is fixed to the support column (1) by the tightening screw (15) constituting the locking clamp (13).

The locking clamp (13) further has a fixing portion (16) which can be fixed to the lower side stairs (S ').

In the embodiment shown in the drawings, the fixing portion (16) is provided with a side downward stair (S ').
It is composed of two plate bodies (18) for receiving the side plates (17) and a tightening screw (19) screwed into one of the plate bodies (18).

1 and 2, the hook clamp (2) of the present invention having the above-mentioned structure is fixed to the upper proper position of the support column (1) with the tightening screw (4), and the proper position of the step of the stairs (S) is obtained. Placed on.

At the same time, the rectangular vertical frame body (6) is fixed by a clamp (7) at a position suitable for lower surface work of the stairs (S). Furthermore, the locking clamp (13) is adjusted up and down, and its fixing portion (16) is fitted to the side plate (17) of the side lower stairs (S '),
It is fixed by a tightening screw (19) provided in the fixing portion (16).

As described above, the support columns (1) are fixed between the stairs (S) and the side lower stairs (S ') with a predetermined space therebetween, and the upper crosspiece (9) of the adjacent rectangular vertical frame (6) is provided. The scaffold plate (F) is placed and fixed between the lower crosspieces (10).

As the scaffolding plate (F), a commercially available scaffolding plate having hooks (20) provided at both ends in advance is used as in the embodiment shown in the drawings, and the hooks (20) are attached to the upper crosspiece ( 9) and the lower rail (10) are used to lock the entire scaffold.

[Effect of device]

ADVANTAGE OF THE INVENTION According to this invention, the labor required for installation and disassembly is not required, the work space is not narrowed, and further, it is easy to handle and economical.
