Abstract

PROBLEM TO BE SOLVED: To make it possible to assemble a fence easily and firmly without using connecting metal fittings or machine screws by erecting poles at predetermined intervals and sequentially inserting pipe connecting portions to the hooks of poles. SOLUTION: A plurality of hook portions 3 are formed in one united body with predetermined intervals in up-down direction at both the side surfaces of the peripheral surface of a pole 1 formed with a cylindrical body with the top end opened. This hook portion 3 is formed to a channel shape with left and right side walls 3a and a front plate 3b. And a U-shaped receiving groove 3c is attached to the front plate 3b. On the other hand, a linking portion 4 of a pipe 2 comprises a neck portion 4a fitted to the receiving groove 3c and an enlarged portion 4b formed at the front portion of the pipe. Then, a leg 1a of the pole 1 is inserted to a hole made in a base block 5 and the poles are arranged at predetermined intervals, and linking portions 4 of the pipes 2 are sequentially inserted to the hook portions 3 thereby assembling the fence linearly.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly fence used for pedestrian safety at a road construction site, a building construction site, etc., and in particular, without using screws or mounting brackets at the site. The present invention relates to an assembly fence that can be easily assembled.

[0002]

2. Description of the Related Art In general, many safety fences for securing pedestrians in road construction or the like, that is, many fences are erected on a base block made of concrete or the like, and are provided with horizontal supports connected to these supports. It is constituted by a crosspiece. The strut and the crosspiece are fixed with dedicated mounting hardware, screws, and the like during assembly.

[0003]

However, since this type of fence is composed of a large number of columns and crossbars, the number of connecting portions between the columns and crossbars is large. Therefore, a lot of connection metal fittings are needed,
Installation took time and assembly and disassembly work was very troublesome.

Accordingly, an object of the present invention is to provide an assembling fence that can be assembled easily, securely, and firmly without using any fittings such as connecting fittings and mounting screws.

[0005]

In order to achieve the above object, the present invention takes the following technical measures. That is, in the assembled fence according to the present invention, the base block 5
And a pipe 2 of a predetermined length detachably connected to the pole 1, and a predetermined interval in a vertical direction on at least one side of a peripheral surface of the pole 1. A plurality of hooks 3 are formed by opening the pipe 2.
Engaging portions 4 detachably fitted to the hook portions 3 at both ends of the
Is provided.

In the present invention, the pole 1 is formed of a cylindrical body having an open upper end, and the lower end of the pole 1 has a small diameter leg 1.
Also, the present invention is characterized in that the leg 1a is formed in such a size that it can be fitted into the upper end opening of the other pole 1 so that the poles can be connected vertically.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. As shown in the drawing, the assembled fence according to the present invention comprises a vertical pole 1 and a horizontal pipe 2 detachably connected to the pole 1.
The pole 1 has a plurality of, for example, three hook portions 3 formed on both sides of the peripheral surface thereof at predetermined intervals in the vertical direction. At both ends of the pipe 2, there are provided engaging portions 4 which are detachably fitted to the hook portions 3.

The pole 1 is formed of a cylindrical body having an open upper end, and is integrally formed with the hooks 3 using a synthetic resin material. Also, a small diameter leg 1 is attached to the lower end of the pole 1.
a is provided, and the leg portion 1 a is formed to have a size that can be fitted into the upper end opening of the other pole 1. That is, the leg 1a
Is formed with a diameter slightly smaller than the inner diameter A formed by the tip of the reinforcing rib 1b provided on the inner surface of the pole 1, as shown in FIG. 4, so that the poles can be connected vertically. ing.

The hook portion 3 shown in this embodiment is formed in a U-shape in plan view by left and right side walls 3a and a front plate 3b. The front plate 3b is provided with a U-shaped receiving groove 3c. I have. The engaging portion 4 of the pipe 2 fitted into the hook portion 3 is formed by a neck portion 4a fitted into the receiving groove 3c and an enlarged portion 4b formed at a front portion thereof.
In the present embodiment, the neck portion 4a and the expanding portion 4b are
Synthetic resin cap 4c over both ends of pipe 2
And are integrally formed.

The above-mentioned assembled fence is constructed by inserting the legs 1a of the poles 1 into the holes formed in the concrete base block 5 and standing upright at predetermined intervals.
By sequentially inserting the engaging portions 4 of the pipes 2 into the hook portions 3, a linear fence can be easily assembled. In this case, one provided with hook portions 3... In three or four directions as shown in FIGS. 7 and 8 is prepared, and by appropriately combining these, the pipes 2. Can be assembled by crossing. If the hook 1 is formed in only one direction as shown in FIG. 6, the end of the fence can be finished well by using it for the end pole of the fence.

The lower leg 1a of the pole 1 is dimensioned so as to fit into the upper opening of the other pole 1 so that the poles can be connected to each other up and down. It is also possible to build a tall fence.

Although the embodiments which are considered to be representative of the present invention have been described above, the present invention is not necessarily limited to the structures of these embodiments. For example, the number of hooks 3 provided on the pole 1 with a vertical space therebetween, the size of the space between the upper and lower hooks, and the like are not specified. Although the pole 1 is formed of a cylindrical body in the above embodiment, it is needless to say that the pole 1 may be formed of a rectangular tube. It is preferable that the pole 1 and the hook 3 are integrally formed of a resin molded product as shown in the above embodiment. However, the pole 1 and the hook 3 are formed of a metal material and fixed by means such as welding. It is also possible to produce. In addition, the present invention has the constituent requirements,
In addition, as long as the above object is achieved and the following effects are obtained, the present invention can be appropriately modified and implemented.

[0013]

Since the assembly fence of the present invention is constructed as described above, the poles are erected at predetermined intervals, and the engaging portions of the pipes are sequentially inserted into the hooks, thereby connecting the fences. Without using any metal fittings such as metal fittings and mounting screws, it is possible to assemble extremely simply and securely and easily disassemble, thereby speeding up work on site.

According to the second aspect of the present invention, the poles can be easily connected to each other up and down, so that a tall fence can be easily assembled according to the situation at the site. .
