BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary handrail which is temporarily constructed on stairs, landings and the like when a building is constructed.

[0002]

2. Description of the Related Art Generally, when constructing a building such as a building, temporary handrails are temporarily constructed on stairs, landings and the like. On the other hand, when a building such as a building is being constructed, as the finishing work progresses, the distribution boards are installed at predetermined floors apart from each other. There is a danger of getting stuck in the steps, obstructing traffic, and catching your foot on the electric wires and falling.

Conventionally, for example, as shown in FIG. 3, an electric wire 15 is fixed to a horizontal column 13 of a temporary handrail for stairs composed of a vertical column 11 and a horizontal column 13 by a wire 17 or the like. Is being done.

[0004]

However, in such a conventional method, since the electric wire 15 is fixed to the horizontal support 13 by a wire 17 or the like, a great amount of work time is required for fixing the electric wire 15. It becomes necessary and the appearance is poor. Further, there is a possibility that the electric wires 15 may be damaged due to the collision of the equipment when transporting the equipment.

The present invention has been made to solve such a conventional problem, and provides a temporary handrail which can easily accommodate an electric wire with good appearance and reduce the possibility of damage to the electric wire. What you want to do.

[0006]

A temporary handrail according to the present invention is a temporary handrail in which a long handrail portion is fixed on a column arranged at a predetermined interval, and the handrail portion is formed by: A lower handrail member fixed to the support, and an upper handrail member detachably engaged with an upper portion of the lower handrail member, are formed .
Shape the convex part that is inserted and fixed between the support parts formed at the upper end.
Forms, between the upper handrail member and the lower handrail member is made by forming a wire receiving space.

[0007]

With the provisional handrail of the present invention, the electric wire is accommodated along the electric wire accommodating space of the lower handrail member with the upper handrail member removed from the lower handrail member, and thereafter, the upper handrail member is moved to the lower handrail member. Locked and fixed.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; FIG. 1 is a cross-sectional view taken along line II of FIG. 2, and FIG. 2 is a perspective view showing one embodiment of a temporary handrail of the present invention. In FIG. 2, reference numeral 21 indicates a column vertically arranged at predetermined intervals on the stairs.

These columns 21 are connected by a connecting member 23 inclined at a predetermined angle from the horizontal direction. Prop 2
A long handrail portion 25 is fixed to an upper portion of 1.
In this embodiment, as shown in FIG. 1, the handrail portion 25 includes a lower handrail member 27 fixed to the column 21 and an upper handrail member detachably engaged with an upper portion of the lower handrail member 27. 29.

An electric wire housing space 31 is formed between the upper handrail member 29 and the lower handrail member 27. That is, the lower handrail member 27 is integrally formed of resin or metal, and is formed of the fixed portion 33 and the wire housing portion 35. The fixing portion 33 is inserted between support portions 37 formed at predetermined intervals above the support column 21, and is fixed to the support portion 37 by screws 39.

The electric wire housing 35 has an electric wire housing space 31 formed therein, and a spherical locking portion 41 at the upper end thereof.
Are formed. On the other hand, the upper handrail member 29 is made of resin or metal, has an electric wire housing space 31 formed therein, and has a spherical locking portion 4 of the lower handrail member 27 at the lower end thereof.
1 is formed with an engaging portion 43 that engages with the engaging portion 1.

The engaging portion 43 is formed by integrally forming a semicircular concave portion 45 inside the lower end of the upper handrail member 29. In this embodiment, as shown in FIG. 2, the lower handrail member 27 is formed with a long hole-shaped electric wire outlet 47. In such a temporary handrail, the electric wire 49 is accommodated in the handrail portion 25 with the upper handrail member 29 removed from the lower handrail member 27 and the lower handrail member 2 removed.
For example, the electric wire 49 such as a cab cable or an F cable is accommodated along the electric wire accommodation space 31 of FIG. It is performed by fixing.

In the temporary handrail constructed as described above, the handrail portion 25 is composed of a lower handrail member 27 fixed to the column 21 and an upper portion which is detachably engaged with an upper portion of the lower handrail member 27. While being formed from the handrail member 29 ,
A support formed on the lower handrail member 29 at the upper end of the column 21
The fixing portion 33 composed of a convex portion inserted and fixed between
Between the upper handrail member 29 and the lower handrail member 27,
Since the electric wire housing space 31 is formed, the electric wires 49 can be easily and beautifully housed, and the risk of damage to the electric wires 49 can be reduced. And the bottom
Supporting part 37 formed at the upper end of support 21 on handrail member 29
Forming a fixing portion 33 consisting of a convex portion inserted and fixed between
As a result, the lower handrail member 29 is quickly and securely attached to the support 21.
You can escape.

That is, in the temporary handrail of the embodiment, the upper handrail member 29 is removed from the lower handrail member 27,
The electric wires 49 extend along the electric wire accommodation space 31 of the lower handrail member 27.
Is accommodated, and the upper handrail member 29 is locked and fixed to the lower handrail member 27, so that the electric wire 49 is accommodated in the temporary handrail.

The electric wire 49 is connected to the handrail 25 of the temporary handrail.
Because it is housed inside, it looks very good. Further, when the equipment and the like are transported, the equipment does not directly collide with the electric wire 49, and the electric wire 49 can be prevented from being damaged. In the above-described embodiment, an example in which the present invention is applied to a temporary handrail of a staircase is described. However, the present invention is not limited to such an example, and is widely applied to, for example, a temporary handrail such as a landing. Of course, you can.

[0016]

As described above, the temporary handrail according to the present invention has the advantages that the electric wire can be easily housed in a good appearance and the possibility of damaging the electric wire can be reduced.
