Abstract

PURPOSE:To obtain a fence provided with a protecting function and convenient in transport and handling by providing a net material, in which a wire rod is swollen out in obverse and reverse sides and partitioned spaces between opposed wires are continuously arranged, and a band plate inserted into each space of the net material. CONSTITUTION:In a net material 1, wire rods are swollen out in obverse and reverse sides of a net surface to continuously form a space 11 between the wire rods and adjacent wire rods are turnably connected by hinges 12. A mesh pitch and size of the space 11 are determind to such a dimension that a band plate 2 can be inserted and possible to suppress looseness in the transverse direction. In the band plate 2, its sectional shape is not only a rectangular shape but also right square and circular shape, lateral width, thickness and total height are determined according to the purpose of use. The band plate 2 is successively inserted into the space 11 for the purpose of reinforcement of the fence and shielding, and blinding and see-through functions are selectively determined. In this way, the band plate 2 can be attached/detached in accordance with the purpose of use so as to facilitate assembling work at a work site.

Description

[Detailed description of the invention] <Industrial field of application><Priorart> It is known that various types of wire mesh are used as fences to prevent intrusion, and at construction sites, strip-shaped fences are used that serve as both a blindfold and protection. Panels are used side by side.

<Problems to be Solved by the Present Invention> The conventional wire mesh fences and panels described above each have the following problems.

<A> Although chain-link fences can be expected to have the effect of preventing intruders, they cannot be expected to have a concealing function.

<Exposure> Many panels are made of steel plates formed into sheet piles to ensure strength, which makes them inconvenient to transport and handle.

Furthermore, since the two panels are attached to the temporary frame at multiple locations using bolts and nuts, it takes time to attach and detach them.

Also, because the panels are just a single piece of board, you can't see through the inside like you would with a chain-link fence.

<Object of the present invention> The present invention was made to solve the above-mentioned problems, and its purpose is to make it convenient to transport and handle, and also to provide a blindfold function as needed while providing a protective function. The objective is to provide a fence that can be used with different viewing functions.

A further object of the present invention is to provide a fence manufacturing method that allows fences to be manufactured easily.

<Means for Solving the Problems> In other words, the present invention provides a steel material in which wire rods protrude from the front side and the back side, and spaces separated between the opposing wires are continuously arranged, and the steel material. It consists of a plurality of strips that are removably inserted into the space.

It's a fence.

Furthermore, the present invention uses a steel material in which wire rods protrude on the front side and back side, and spaces spaced apart between the opposing wires are continuously arranged, and a strip is inserted into each space of the steel material. This is a fence manufacturing method that involves inserting.

<Description of the present invention> The present invention will be described below with reference to the drawings.

<A> Fence FIG. 1 shows an example of a fence according to the present invention.

The fence is composed of a steel material 1 and a plurality of strip plates 2 inserted into the steel material 1.

<Exit> Steel material Figure 2 shows a partial cross-sectional view of the fence taken along the horizontal direction.

Steel material 1 has wire rods protruding from the front and back sides of the mesh surface,
A well-known diamond-shaped wire mesh or wire lath can be used as a mesh in which a space 11 is continuously formed between the wire rods and adjacent wire rods are rotatably connected by a hinge 12.

As other materials for the steel material 1, crimp wire mesh or expanded metal wire protruding from the front and back sides can be used.

The mesh pitch of the steel material 1 and the size of the space 11 must be set to dimensions that allow insertion of the strip plate 2 and also suppress horizontal wobbling.

<C> Strip board The strip board 2 is a board for the purpose of reinforcing and shielding the fence, and can be made of materials such as resin or wood, and has a width, thickness,
The overall height will be determined depending on the purpose of use.

The cross-sectional shape of the strip plate 2 is not limited to the rectangular shape shown, but may be square, polygonal, circular, oval, or the like.

<2> Measures to prevent strips from falling off If the strips 2 are used with the lower end touching the ground, there is no problem of the strips 2 falling off, but if the strips 2 are installed with the lower end away from the ground, etc. As shown in FIG. 3, a method of supporting the lower part of the strip plate 2 by bending the end line 13 extending from the lower end of the steel material 1 can be considered.

Alternatively, an angle member having a trowel-shaped cross section may be used, and the entire strip plate 2 and the lower part of the steel material 1 may be gripped and the angle member may be fixed to a temporary frame or the like.

<Manufacturing method> In the present invention, it is only necessary to sequentially insert the strips 2 into the spaces 11 of the steel material 1.

The strip plate 2 may be inserted before use at a factory or other site, or the strip plate 2 may be inserted into the space 11 from above after parts of the steel material 1 are attached to a temporary frame at the site.

〈Operation〉〈A〉 How to use: Roll up the fence and unfold it on site.

Then, the unfolded fence is propped up against a temporary frame made of pipe materials arranged vertically and horizontally, and the parts between the two are fixed in place.

<Opening> Blindfolding function Since the fence of the present invention has strips 2 arranged continuously with gaps between the 12 hinges, a blindfolding effect can be expected.

This blinding effect is caused by the difference between the strip plate 2 and the hinge 12 gap width.
The larger the width ratio, the more noticeable it becomes.

<C> Since the strength of both the protective function steel material 1 and the strip plate 2 is exhibited synergistically, the wire rod and the strip plate 2 constituting the steel material 1 can be designed to have low strengths, respectively.

<2> If the strip plate 2 is removed over a necessary range from the transparent functional steel material 1, that range can be seen through.

Since the strip plate 2 is simply inserted into the steel material 1 without using fixing tools such as bolts or nuts, the strip plate 2 can be easily removed.

<Other Modifications> In the above embodiment, the case where the strip plate 2 is oriented vertically with respect to the steel material 1 has been explained. However, if the spaces 11 of the steel material 2 are arranged diagonally, the strip plate 2 can be arranged in a vertical direction. It can be installed at an angle.

<Effects of the Present Invention> Since the present invention is as described above, the following effects can be obtained.

<B> The strength of the fence is uniform because the steel is in even contact with the strip.

Moreover, since the steel material and the strip plate complement each other in strength, the steel material and the strip plate can be designed to have low strength.

<mouth> The band can be removed depending on the purpose of use, so
It can be used blindfolded or transparently.

<C> Convenient for transportation and handling.

Additionally, because the installation is completed by simply rolling out the rounded fence and fixing it in place, on-site assembly is extremely easy compared to installing conventional panels.

2〉 Since the fence is foldable, it is convenient for transportation and storage.

<E> It can be applied to various purposes and has a wide range of uses.
