Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a temporary handrail that can be installed without a pre-arranged mounting base.

[0002]

2. Description of the Related Art As a conventional handrail that can be assembled and removed, a mounting base such as an anchor or an anchor hole is previously arranged at a predetermined position, and the predetermined position is provided through these mounting bases. It is assembled only in.

As a device that can be installed at any place without requiring a specially arranged mounting base as described above, a standing stand of a fixed length of 1 to 2 m having a tread that can be carried or a standing stand that can be carried. There are those that hang the rope between poles, or those that use the pillars at construction sites to lay the rope.

[0004]

In the former one of those described in the prior art, the stability is almost the same as that of the fixed one because it is through the mounting foundation, but its installation location is predetermined. It has a problem that it is limited to the place where the mounting base is provided.

In the latter case, there is a problem that the stability is almost non-existent, and the stability is merely calm, and the safety is not guaranteed at all.

The present invention has been made in view of the above problems of the prior art. The object of the present invention is to provide a preliminary arrangement having excellent stability and safety. The purpose of the present invention is to provide a temporary handrail that can be installed / removed freely and can be installed in any place without requiring a mounting base that must be installed.

[0007]

In order to achieve the above object, a temporary handrail according to the present invention has a stacking step portion having a bolt through hole for interconnecting at one end and the bolt at the other end. It has a planting anchor bolt corresponding to the through hole, and further has a base plate projecting an engaging cylinder part for fitting and fixing a cylindrical column at a predetermined part of the central part, and a planar lattice fence on its side surface. It is configured to include the tubular column having an attachment portion and the planar lattice fence in which an assembly portion for the attachment portion of the tubular column is provided on a side surface thereof.

At one end, there is a step portion for overlapping with a bolt through hole for interconnection, and at the other end there is a planting anchor bolt corresponding to the bolt through hole. -Shaped base plate with anchor bolts for fixing the lower horizontal bending part, and the plate-shaped column having an engagement part with the planar lattice fence on its side surface, and the attachment of the plate-shaped column on its side surface. The above-mentioned planar lattice fence is provided with an assembly portion for the portion.

It is preferable that each of the above-mentioned members is made of lightweight steel material.

[0010]

Since the temporary handrail constituent members are plate-shaped, plane-shaped, and column-shaped, respectively, they can be stored without being bulky at the time of disassembly. In addition, at the time of assembly, the base plate and the lattice fences are continuously elongated to stabilize as a three-dimensional mutual support body. Further, the elongated base plate is fixed without excessive sliding due to the friction effect produced by its large combined weight and contact area.

[0011]

EXAMPLES Examples will be described with reference to the drawings.

1 to 5, the base plates 1, ... As units are set to dimensions suitable for handling during storage and transportation, and one end thereof is a stepped portion 2 in a rising shape for overlapping. ... and anchor bolts 3 for connection are planted at the other end. As a matter of course, the stepped portions 2, ... Are provided with through holes 4, ... For the anchor bolts 3 ,. As a result of the above, the plates 1, ...

In FIGS. 1, 2, and 4, the plate 1 is shown.
Square or circular connecting cylinders 5, ... Are provided in a protruding manner at a predetermined portion of the central portion of the cylinder for fitting and fixing a cylindrical column to be described later.

As described above, the cylindrical columns 6, ... Are removably fitted in the connecting cylinders 5, ... And are fixed via fastening bolts. On the side surfaces of the cylindrical pillars 6, ..., Joining portions 7 ,.

The above-mentioned planar lattice fences 8, ... Are provided on their side surfaces with an assembly portion that meshes with the fitting portions 7, ..., Through the through bolts 9 ,. Erected in.

As described above, as shown in FIG. 4, the cylindrical columns 6, ... On the base plates 1, ...
Are adjacent to each other in a row, and the planar lattice fences 8 are installed between the pillars 6. This is not connected to the floor via some mounting foundation pre-disposed on the installation floor, but merely placed. But,
It is stable by mutual support by continuation and resists sliding by friction of the total contact area backed up by the united weight, so it is almost fixed and stable.

The most preferred mode of use is shown in FIG. That is, when the continuous body 10 of the handrail of the present invention is completely surrounded by a predetermined floor surface 11 as shown in the drawing, the whole body reasonably communicates with each other. It can be used for non-walking rooftops for temporary use at events and for fall prevention at construction sites. Long-term use is also possible. If complete enclosure cannot be achieved and there is no choice but to break off,
It will be safe when combined with pillars, walls, etc.

FIG. 3 shows a case where plate-like columns 12, ... Are assembled in place of the cylindrical column 6. That is, the anchor bolts 13, ...
Are planted, and the lower horizontal bent portion 14 of the plate-shaped column 12 is fastened and fixed via this. Plate pillar 1
On the side surface of 2, ..., the connecting portion 15, for the planar lattice fence 8 ,.
... is provided, and the fence 8 is detachably assembled.

If each of the assembly members of the present invention is made of a lightweight steel material, the durability is excellent, and the friction effect on the floor surface can be greatly expected from the total weight.

[0020]

Since the present invention is configured as described above, it has the following effects. 1. It can be installed even if the floor to be installed does not have a pre-installed foundation, which is convenient for curing rooftops and the like without handrails installed in advance. 2. Since each constituent member is a plate, a surface, and a columnar body, it is not bundled and bulky, which is convenient for storage and transportation. 3. By the friction effect that is summed up by the connection,
It is safe because it gives the same stability as when fixed. 4. By linking, each fence is stable and safe by mutual support, so it is much safer than the method of placing a short fence alone or laying a rope.
