Description

[Detailed Description of the Invention] The present invention relates to a wire mesh to be installed on the top of a block wall, etc.

Generally, when installing wire mesh on top of a block wall, posts are set up at appropriate intervals to match the holes in the blocks at the top of the block wall, and wire mesh, etc. is stretched between these posts. The position of the holes varies depending on the stacking error of the blocks and the type of blocks, and if the length of the wire mesh does not match the length of the block wall, there are drawbacks such as difficulty in installing the wire mesh.

Therefore, the present invention forms a shelf net by integrally providing groove-shaped support sections and insertion sections at both ends of a wire mesh, and connects them by fitting the insertion sections of adjacent shelf nets into the support sections. ,
The shelf net is configured so that its position can be adjusted, thereby making it possible to install wire netting on the top of a block wall, etc., extremely easily and quickly.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In FIGS. 1 and 2, 1 is a block wall constructed of a large number of concrete blocks 2, 2... A wire mesh-like structure is installed at the upper end of the wire mesh-like structure 3, and the wire mesh-like structure 3 has a large number of shelf nets 4, 4 arranged in the length direction.
It is made up of.

The shelf net 4 is first formed by crossing and abutting a large number of arranged vertical strands 5 with horizontal strands 6 perpendicular to them, and welding and integrating the contact portions by electric resistance welding or the like, to form a wire mesh. Next, at both ends of the wire mesh, wide groove-shaped support portions 7.7 which are bent at the ends and open in a direction perpendicular to the surface of the wire mesh are vertically provided in opposite directions, and the support portions 7.7 An inset part 8°8 is formed on the edge of the wire mesh to project perpendicularly from the surface of the wire mesh, and these strut parts 7, 7, inset part 8°8, and rope part 9 are constructed as one body. When installing the wire netting 3, the legs 7a at the lower ends of the support columns 7 of the multiple shelf nets 4, 4, . . . are inserted into the holes of the blocks 2, and the adjacent shelf nets are , the fitting part of the other shelf net is fitted into the support part of one shelf net so that it can be moved left and right, and the position of each fence net 4 is adjusted left and right within the range in which the fitting part 8 can move within the support part 7. By adjusting the position of the leg part 7a and the hole on the block, the position of the leg part 7a and the hole on the block is adjusted, and then the support part 7 and the fitting part 8 are
The vertical strands 5, 5 or the horizontal strands 6, 6 are connected to each other, and the leg 7a at the lower end of the support 7 is fixed with mortar or the like.

In this case, the leg portion 7a may be previously provided integrally with the lower end of the support portion 7 by extending the lower end of the vertical strand 5, but the vertical strand 7 may not be formed long in advance. The leg portions 7a may be formed later by connecting similar wires or other members.

In addition, in the above embodiment, the rims, crossbars, etc. at the top and bottom of the shelf net are omitted, but by narrowing the interval between the horizontal strands at the top and bottom ends of the shelf net, the strength of the top and bottom ends of the shelf net can be increased. Alternatively, by bending the upper end of the rope horizontally or into a cylindrical shape, it can be used as a rim or crosspiece, or it can be used as a shinogaeshi that can be installed on top of a block wall with a high X. In this case, the tips of the vertical wires can be left as they are.

Further, the connecting fitting 10 may be of any type as long as it can connect the horizontal strands or the vertical strands in the support section 7 and the insertion section 8 as shown in FIG. 2, and for example, as shown in FIG. 3. In this case, it is possible to use a connecting fitting in which the two opposing pieces 10a and 10b, which are made to freely move the twill wire by screws 11, are provided with unevenness 10C, and when connecting vertical strands with these connecting fittings 10. In terms of strength, it is preferable to connect the wires as close to the horizontal strands as possible.

In the embodiment shown in FIG. 4, support columns 7.7 are provided at both ends of the wire mesh in the same direction.

In each of the above embodiments, the leg portions 7a were provided only on the vertical strands in the struts 7, 7, but similar leg portions were provided integrally or at the lower ends of all or some of the vertical strands in the rope portion 9. It is also possible to extend them as separate pieces and insert and fix them into the holes of the block 2.

Furthermore, in the above embodiment, the case where the wire mesh fence is erected on top of the block wall has been described, but the wire mesh fence can be used in other places where the position of the pillars is limited in the same way as in the case of the block wall. Of course, it is also possible to install

According to the present invention having the above configuration, the groove-shaped support portions and the inset portions are integrally formed at both ends of the wire netting, and are connected to the support portions of the adjacent shelf netting so as to be movable and adjustable from side to side. , the position of each shelf network can be arbitrarily adjusted within the width of the support section, and therefore, slight errors may occur in the positions of the holes for inserting and standing up the support sections due to block stacking errors, etc. However, by absorbing this error, each shelf net can be reliably installed on the block wall, and furthermore, by forming support sections at the inner ends of the shelf nets and fitting them into each other, Not only is there no need to separately prepare expensive posts made of iron pipes, but the shelf net with integrated posts makes it easy to create a wire mesh fence with almost no distinction between the front and back, and the supporting force of the posts is uniform on both the front and back sides. Can be configured.
