Description

[Detailed description of the invention] Industrial application field The present invention relates to a mechanism for attaching wire mesh to the rim of a fence, and more specifically, to lock a wire mesh or expanded metal inside the rim, which is a component of a fence. This relates to the structure of the suspension wire used for this purpose.

Conventional technology Fence structures and walls are constructed around expressways and Shinkansen tracks in order to prevent outsiders, such as children, from entering them, and to clearly mark the boundaries of the premises. ing. These constructs are
In addition to having physical strength that can withstand long-term use, there is a strong demand for simpler component structures in order to reduce construction costs and ease construction. In response to such demands, for example, Japanese Utility Model Application Publication No. 123228/1983,
Publication No. 111535 or Japanese Utility Model Publication No. 18034/1983 proposes a wire mesh fixing mechanism in which hanging wires and wire mesh or expanded metal are attached to the inside of the rim when constructing a fence or fence.

Problems to be solved by the invention However, with the wire mesh fixing mechanism as described above, it is necessary to prepare a wire mesh fixing tool separately from the hanging wire.
Its overall structure is not necessarily sufficiently simplified. For this reason, the fixing function of wire mesh is generally low, and the workability is also poor. Therefore, it is difficult to achieve the desired effects in improving the service life of the fence and saving labor in construction work.

The main purpose of the present invention is to provide a mechanism for attaching wire mesh to the edge of a fence, which has a simple structure and is easy to install, which can eliminate the above-mentioned disadvantages of conventional wire mesh fixing mechanisms. There is a particular thing.

Another main object of the present invention is to provide a highly durable wire mesh tensioning mechanism that can be placed within the fence in a state in which the wire mesh, which is a fence component, and the hanging wire are firmly connected. .

Means for Solving the Problems In view of this purpose, the present invention provides a suspension wire 2 for suspending the upper and lower ends of a wire mesh or an expanded metal 1.
and a rim 4 provided with an insertion opening 3 for the suspension wire 2, and the suspension wire 2 is made of a coiled wire having a helical pitch P that is approximately equal to the pitch when the wire mesh or expanded metal 1 is stretched. The gist of this invention is a wire mesh covering structure for the fence rim, which is characterized by the following structure.

Effect According to the present invention, the wire mesh or expanded metal 1 has a spiral pitch P that is approximately equal to the loop 5 of the wire mesh or the expanded metal 1.
Since the coiled wire 2 having a diameter is fixed in the furring 4, the fence can be stretched between the fence supports at a predetermined pitch without using any other fasteners.

Embodiment FIG. 1 is a perspective view illustrating an embodiment of the present invention. As shown in the figure, an insertion opening 3 for the expanded metal 1 and its suspension wire 2 is opened at the end face of the furring rim 4, and the expanded metal 1 and side bars (not shown) are provided in the generatrix direction of the furring 4. An opening flange 6 is provided for insertion. On the other hand, the hanging wire 2 is formed from a steel wire wound into a coil, and its coil pitch is such that it can travel spirally through a loop 5 formed along the upper and lower edges of the expanded metal 1. Designed. That is, the hanging wire 2 is connected to the adjacent loops 5, 5.
A helical pitch P approximately equal to that of the loop 5 is provided so that one coil 8 can be placed between the loops 5 and 5.

When attaching the expanded metal 1 to the trunk rim 4, first turn the suspension line 2 along its longitudinal direction,
The tip of the suspension wire 2 is inserted into the first loop 5 of the expanded metal 1, and thereafter the suspension wire 2 is rotated forward into the expanded metal 1 so that one coil 8 is placed between adjacent loops 5, 5. Repeat over the entire width. When the insertion of the suspension wire 2 into the loops 5, 5... is completed, both ends 7 of the suspension wire 2 are bent and fixed to the expanded metal 1, and in this state, the expanded metal 1 and the suspension wire 2 are attached to the rim 4. It is inserted into the flanges 4 through the inserted insertion opening 3 and between the opening flanges 6, 6. Thereafter, the fence is constructed by attaching the furring 4 to fence supports (not shown) in accordance with a conventional method.

Effects of the invention If the upper and lower ends of wire mesh or expanded metal are not fastened together, the shape of the mesh becomes vertically elongated or flat, making it uncertain and the mesh pitch easily changing. ,
Since the hanging wire is made of a coiled wire having a helical pitch that is approximately the same as the predetermined pitch when the expanded metal is stretched, it can be easily, accurately, and quickly set at the predetermined pitch without using any special fixing equipment. Can do fence installation work. Therefore, the present invention can greatly exceed the conventional technology in terms of simplifying the structure of the fence and saving labor in construction work.
