Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a guard fence that is installed in civil engineering works, construction sites, etc. to surround a work place and maintain safety.

[0002]

2. Description of the Related Art Hitherto, there has been known a guard fence in which an outer frame and a leg portion are integrally formed by a metal pipe, and a wire net or a fiber net is stretched inside the outer frame.

[0003]

The guard fence in which the outer frame and the legs are integrally formed with a conventional metal pipe and a wire mesh or the like is stretched inside the outer frame has the legs protruding from the outer frame. When storing or transporting a guard fence, more storage space or storage space is required. It often happened that it could not be used as a guard fence even though it was not damaged.

Further, since a guard fence in which an outer frame and a leg are integrally formed by a metal pipe has a variation in the interval between the legs, a guard to be connected to a hole provided at an upper end of one guard fence is provided. There are problems such as the inability to insert the legs of the fence or the troublesome connection, resulting in poor work efficiency.

Further, when the guard fences are connected to form an enclosure, it is not always necessary to attach the legs to the pillars or bury them in the ground, but to simply connect the guard fences in a square shape. In such cases, the enclosure without the legs will be more stable, and if the guard fence is attached to the pillar, there will be a gap between the lower end of the guard fence and the ground. It is not preferable because an object can enter through this gap.

Further, in the case where the guard fence is integrally formed of a synthetic resin from the viewpoint of reducing the weight of the guard fence or preventing rust, etc., the molding process becomes complicated due to the presence of the legs, and the molding is also difficult. There is a problem that the structure of the guard fence is limited or the manufacturing cost increases.

An object of the present invention is to solve the problems of the conventional guard fence as described above, and to provide a guard fence which is excellent in assembling workability, handling and handling such as transportation and storage, and is lightweight and has high installation stability. Is to do.

As shown in FIG. 1, the vertical frame y is provided with a plate-like inner frame 9 and an outer frame 10 which extend in a vertical direction and are parallel to each other. The above-mentioned vertical ribs 2 and horizontal ribs 3 are arranged. The inner diameter of the upper insertion tube 4 and the lower insertion tube 5 in the vicinity of the opening 11 is formed in a tapered shape expanding toward the opening so that a connecting tube described later can be easily inserted.

The lower insertion tube 5 is provided with a through hole 12 into which a locking piece provided in a connecting tube described later is inserted.
The through hole 12 is, as shown in FIG.
The guard fence body F is provided at two places, a front side F1 and a back side F2. A through hole 13 ′ is formed in the bottom portion 13 of the lower insertion tube 5 opposite to the opening 11, and a through hole 13 ″ is also formed in the vertical rib 2 adjacent to the through hole 13 ′. It is configured such that foreign substances such as dust or rainwater, water used for washing, etc. which have entered the lower insertion pipe 5 can be discharged, and the same configuration is provided for the upper insertion pipe 4. That is, a through hole 14 'is also formed in the bottom portion 14 of the upper insertion tube 4, and a through hole 14 "is formed in the vertical rib 2 adjacent to the through hole 14'.

Next, the connecting pipe C will be described with reference to FIG. 3 which is a perspective view of the connecting pipe C. The connecting pipe C is formed in a substantially cylindrical shape, and has a length that is approximately twice the depth of the upper insertion pipe 4 or the lower insertion pipe 5 described above. When connecting the guard fence main body F, approximately half of the connecting pipe C is inserted into the upper insertion pipe 4 of the guard fence main body F located below, and the other approximately half of the lower part of the guard fence main body F located above. It is inserted into the insertion tube 5 so that no gap is formed between the guard fence bodies F. In the case where a gap is required between the stacked guard fence bodies, a bulging portion having a diameter larger than the inner diameter of the upper insertion pipe 4 or the lower insertion pipe 5 is provided near the center of the connecting pipe C, or A gap can be provided by appropriately lengthening the connecting pipe C.

As described above, the upper insertion tube 4 of the connecting tube C
In order to facilitate insertion into the lower insertion tube 5 and the upper insertion tube 4 and the lower insertion tube 5, the vicinity of the opening 11

[Effects of the Invention] Since the present invention is configured as described above, it has the following effects.

Since the guard fence is composed of a guard fence body without legs and a connecting pipe separate from the guard fence body, storage or storage space can be reduced, and an object can be placed on the legs like a conventional guard fence. Since the legs do not bend or break due to the collision, the workability or handleability of transporting and assembling the guard fence is improved.

[0021] Even if the guard fence main body has manufacturing variations, it is easy to insert the connecting pipe into the upper insertion pipe or the lower insertion pipe, so that the assembling workability is remarkably improved. That is, it is possible to solve a problem that a leg portion of a guard fence to be connected cannot be inserted as in the case of a conventional guard fence, or that connection is troublesome and work efficiency is deteriorated.

When the guard fence main body is connected to form an enclosure, there is no gap between the lower end of the guard fence main body and the ground. Can be prevented.

When the guard fence is integrally formed of synthetic resin, since the guard fence body has no legs, the molding process can be simplified and restrictions on the structure of the guard fence body are reduced, and the manufacturing cost is reduced. Reduction and diversification of products can be achieved.
