Abstract

PROBLEM TO BE SOLVED: To develop a fence structure in a fence for a heavey snow area with high plane rigidity by applying integral welding by using a member (furring strip) with high section modulus and a linear element in order to correspond to the fence for the heavy snow area. SOLUTION: In the fence for the heavy snow area, the fence structure in the fence for the heavy snow area is so constituted that the regular linear element 1 is used in the vertical direction, the furring strip 2 having a channel- shaped section is provided in the horizontal direction and that two spots of a contact section between the vertical linear element 1 and the furring strip are respectively welded.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a fence structure for a fence for heavy snowfall.

[0002]

2. Description of the Related Art In conventional fences for heavy snowfall, it is necessary to consider the load caused by snowfall. However, as in the case of ordinary fences, a wire mesh (fence surface) is provided with a slightly thicker wire mesh. The wire netting and the body edge on which the wire netting is erected are produced separately, and are united by screws, rivets, welding or the like.

[0003] Therefore, in this means, rigidity is not sufficiently exhibited because integration in a pure sense is not performed.
In addition, it takes time to assemble for integration and the like, and the joining surfaces of the vertical member and the horizontal member have a shift noise and rust, and various problems have occurred.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and a member (body member) having a large section modulus is required to cope with a fence in heavy snowfall. Another object of the present invention is to develop a fence structure for heavy snowfall fences that increases surface rigidity by performing integral welding using a wire and a wire.

[0005]

As means for solving the problem, a conventional wire rod as a vertical member and a cross-sectional body-shaped iron plate having a channel-like cross section are provided as cross members. The fence structure of a fence for heavy snowfall, which is formed by welding two places in contact with a vertical wire rod, is obtained.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
In a fence for heavy snowfall, a wire rod (1) is used in the vertical direction, a body edge member (2) having a channel-shaped cross section is provided in the horizontal direction, and a wire rod (1) in the vertical direction is provided. And the contact portion between the channel-shaped body material (2) and
It consists of a fence structure for fences for heavy snowfall, characterized by welding at different locations. (See Fig. 6)

Next, another embodiment of the present invention will be described with reference to FIG. 2. In a fence for heavy snowfall, a normal wire rod (1) is used in a vertical direction, and a cross section is formed in a horizontal direction. Shape of the rim material (2) (2 ')
Characterized in that a total of four contact portions between the longitudinal wire (1) and the facing body edge material (2) are welded to each other, with a total of four locations being welded. It consists of fence structure in fence. (See Fig. 6)

The general cross-sectional shape of the channel-shaped rim member (2) is a U-shape shown in FIGS.
Then, as shown in FIG. 3, (a) a semicircle, (b) a parabola, (c) a U-shape, (d) a V-shape, etc. are conceivable.
Other shapes may be used, and those used in the present invention are selected from these, and the welding is performed by spot welding.

As shown in FIG. 4 (a), the longitudinal end of the wire rod (1) is treated in the same direction as the longitudinal direction of the shell material (2), as shown in FIG. As shown in FIG. 3 (b), it may be processed by bending it into a cylindrical shape in a direction orthogonal to the shell material (2), and as shown in FIG. ).

[0010]

According to the present invention, a normal wire rod (1) is used in the vertical direction, a body edge member (2) having a channel-like cross section is provided in the horizontal direction, and the vertical wire rod (1) is used. When two contact portions with the body member (2) are provided and the body member (2) is opposed to each other with the longitudinal wire (1) interposed therebetween, four parts are provided to the welding means, respectively. Because of this, the vertical wire and the horizontal rim (2) that make up the fence can be fixed firmly, there is no noise caused by strong wind, and there is no rust due to snow and rain. Leading to increased rigidity,
In the plating process and the like, the channel-shaped body material (2) has an extremely beneficial effect, such as difficulty in accumulation and dripping of the processing liquid.
