Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handrail for temporary stairs on a temporary scaffold installed for construction work or maintenance of a building.

[0002]

2. Description of the Related Art Conventional handrails for temporary stairs have been constructed by cutting and welding pipes or the like in accordance with the site of each individual staircase, and a clamp provided with the handrail is attached to a bite support. is there. However, since the construction of the handrail is time-consuming, there is a fence-like handrail that is used to engage with the stairs. However, the installation state may not be stable, and there is a problem in safety.

[0003]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a handrail for a temporary staircase which can be stably installed by attaching a clamp to a vitality pillar without requiring a pre-assembled fence, and which can be used on either the left or right side. Is provided. Another object of the present invention is to provide a handrail for a temporary staircase in which the length of the handrail can be adjusted so that the clamp can be securely attached to the pillar.

[0004]

SUMMARY OF THE INVENTION Accordingly, the present invention provides a mounting plate at the front and rear ends of an inclined handrail, and connects a turning member capable of being vertically displaced by 180 degrees to the mounting plate. A temporary handrail for stairs, having a clamp provided on one side of a deflection member and attached to a pillar. A mounting plate is provided at the front and rear ends of the two upper and lower handrails in parallel, and a turning member that can be vertically displaced by 180 degrees is connected to the upper portion of the mounting plate, and one side of the turning member is provided. , May be provided with a clamp to be attached to the pillar. Further, the handrail may be made extendable and adjustable in length.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the present invention will be described below with reference to illustrated embodiments. In the embodiment shown in FIGS. 1 and 2,
Reference numeral 1 denotes a pipe-shaped handrail, and an outer tube 10 is attached to an inner tube 11.
Is inserted and made to be expandable and contractible, and the inner cylinder tube 11 is fixed by crimping with the thumb screw 12. 2 is a lower handrail for drop prevention,
Similarly, the inner tube 21 is inserted into the outer tube 20 so as to be expandable and contractible, and the inner tube 11 is crimped and fixed with the thumb screw 22.

[0006] The upper and lower handrails 1 and 2 are inclined in parallel,
The mounting plate 3 is vertically fixed to the front and rear end portions by welding, and the reinforcing tube 4 is fixedly interposed between the outer cylindrical tubes 20 of the upper and lower handrails 1 and 2.

[0007] On the upper part of the front and rear mounting plates 3, a board portion 6 is provided.
An angle-shaped diverting member 6 composed of 1 and a bent piece 62 is connected to each other, and a clamp 7 attached to the bit 8 is fixed to the bent piece 62. That is, the board portion 61 is fixed to the mounting plate 3 with the bolt and nut 5 so as to be rotatable in the vertical direction, and the clamp 7 protrudes from the bent piece portion 62 arranged on the side.

In this embodiment constructed as described above, as shown in FIG. 3, a handrail can be easily provided on a temporary staircase only by attaching the front and rear clamps 7 to the front and rear bit columns 8. At this time, since the handrail 1 is disposed inside the clamp 7, there is no obstruction to the bitity support 8 and the clamp 7. By adjusting the length of the stretchable handrail, the clamp 7 can be securely attached to the front and rear bit supports 8. In addition, if it is attached as shown in FIG. 4, the handrail can be connected continuously.

In this handrail, the clamp 7 can be arranged on the opposite side by rotating the deflecting member 180 by 180 degrees vertically because the mounting portion of the substrate portion 61 rotates, as shown in FIG. Can be used as a handrail on the opposite side. That is, it can be used as a left or right handrail by rotating the deflecting member 6 by 180 degrees.

Although the present embodiment has the above-described configuration, the present invention is not limited to this. For example, the handrail material,
Regardless of the shape and structure, the shape and structure of the mounting plate fixed to the front and rear ends are not limited. Therefore, the handrail may be provided with one upper handrail, or may be a handrail that does not expand and contract. Further, the shape and configuration of the deflecting member connected to the mounting plate and the connecting means for rotating and displacing 180 degrees vertically are also appropriate. Further, the configuration of the clamp for mounting the pillars provided on the deflection member is also optional. In addition, when making a handrail extendable, the structure does not matter.

[0011]

According to the first aspect of the present invention, the handrail for the temporary staircase can be easily arranged simply by attaching to the bite support by the front and rear clamps. In the third aspect, the length of the handrail can be adjusted, and the handrail can be reliably mounted on the pillar.
