Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a frame member made of fiber reinforced plastic or the like, a nonmetallic net being stretched to form a fence, and a nonmetallic frame for partial removal. The present invention relates to a fence fixing frame member and a fixing device.

[0002]

2. Description of the Related Art Many fences conventionally used for protecting various outdoor facilities are made of metal and have low durability against salt damage and chemical damage, and electromagnetic induction occurs near electric facilities. However, there are problems such as power loss, heat generation of members, electric corrosion, and electrical insulation. Accordingly, plastic nets and frame members made of fiber reinforced plastic (hereinafter referred to as FRP) have been considered instead of metal fences in recent years.

Therefore, there has been proposed a synthetic resin fence having a frame made of fiber-reinforced synthetic resin and having a support and a rim, and a net made of polyethylene terephthalate in the frame (Japanese Patent Application Laid-Open No. 9-279910).

[0004]

When FRP is used to stop the fence of the plastic net,
Since the metal cannot be fixed by welding as in the case of metal, it is difficult to provide a fixing part for the net, and there is a problem that the fixing with a pin or a bolt tends to be incomplete. For example, when an external force acts on the fence, a local stress acts only on the fastening portion. Therefore, it is considered that a fastening structure in which a uniform force is applied to the entire net without such a stress has been desired.

In the above-mentioned known invention, since the end support member is suspended in the body edge, it is partially removed (for example, only the net between the desired columns is replaced after assembly and fixing). There was a problem that could not be done. Therefore, there is a problem in that the workability is poor because it is necessary to assemble the fences one by one.

[0006]

According to the present invention, however, a support member is inserted and hooked on the edge of a non-metallic net, and
The above-mentioned conventional problem was solved by sandwiching the mesh hooked on the portion with the mounting ribs of the columns and the mounting ribs of the trunk. In addition, by connecting the body edges with joints at each strut, the fence installation work for each section has been facilitated, workability has been improved, and the construction period has been shortened, thereby reducing the construction cost. . Also, when repairing a fence, only the section to be repaired can be easily replaced.

That is, the present invention provides a non-metallic end support member which is inserted into and hooked to an edge of a non-metallic net, and fixing of the same or similar strut and body edge for fixing the end support member. A frame member for fixing a non-metallic fence, comprising a member and fixing means for connecting and fixing the members. The non-metal net is a plastic net or a plastic-reinforced synthetic fiber net, and the non-metal end support member, the support and the rim are a fiber-reinforced plastic end support member, It is a pillar and a rim.

In another aspect of the invention, an end supporting member is inserted around four sides of a fence made of a non-metallic net, and the edge of the net with the end supporting member is connected to a mounting rib on a side surface of a column and two ribs.

Therefore, it has a similar shape to the cross-sectional shape of the body edge (excluding the mounting ribs), and can be inserted into the inside of the body edge and fixed by tightening the body edge. Also, depending on the structure of the fixing device of the fence, it is conceivable that the hooking portion between the support member and the net edge may enter deeply into the body edge, but in such a fixing device, A groove is provided so that the support member can be inserted.

The supporting member used in the present invention is made of FRP, has a length substantially equal to the peripheral length of the plastic net, has bolt holes formed at appropriate intervals, and has a mounting rib and a supporting member. Used to fix.

According to the fence of the present invention, the upper and lower edges of the plastic net and the supporting members are inserted into the crevice of the body edge, and are fastened and fixed with bolts. Insert between the ribs and tighten with bolts. Therefore, the edges of the plastic net are clamped by the support members and the mounting ribs, and are uniformly tightened and fixed. Therefore, when an external force is applied to the fence, the forces are dispersed over the entire edges and the stress is reduced. Since there is no risk of local concentration, there is no risk of the plastic net breaking down locally.

The work of stretching the plastic net in the fence of the present invention can be performed at an appropriate position for one section regardless of before and after the installation of the fence post, because of the joint at the trunk edge. Very well, it can be installed from a convenient place.

Further, in the present invention, the rim can be removed by moving the joint, so that it can be removed and replaced for each fence between the columns, or the passage is changed during construction, and a plastic net can be stretched. Release is easy.
