Description

  The present invention relates to a grid body formed by arranging a plurality of wire rods in a grid pattern and a fence using the grid body.

  2. Description of the Related Art Conventionally, as a fence installed at a site boundary, an adjacent land boundary, a road cover, or the like, a fence in which a lattice formed using a wire rod is supported between columns is used. For this lattice body, a rhombus wire mesh knitted in a rhombus shape using a plurality of wire rods, and a mesh wire mesh in which wires are arranged vertically and horizontally and their intersections are welded are employed.

  The grid body is generally rectangular and easy to install on a horizontal ground, but when installed on an inclined ground, the grid shape of the grid body is made into a parallelogram according to the slope, It is necessary to tilt the grid body and install it. However, the former needs to measure the inclination angle of an installation place each time in the field, and it is not efficient to create a metal net for every inclination angle. In the latter case, when fixing the wire mesh body to the support column, the position of the wire crossing the support column is not constant, so it is necessary to adjust the fixing position, and there may be a place where it overlaps with the adjacent wire mesh body. There is concern about the decline.

  For example, in Patent Document 1, a vertical line of a wire mesh formed by weaving wires in a vertical and horizontal direction is configured in a straight line, and a horizontal line is a wave of a plurality of wires that are made close to each other by corrugation processing. There has been proposed a lattice metal mesh configured to sandwich the vertical line between the valleys.

  In addition, as shown in Patent Document 2, the present applicant also deforms a square wire mesh formed by wrapping a vertical wire strip in a loop shape at the intersection of the vertical wire strip and the horizontal wire strip, or diagonally. An inclined wire mesh fence has been proposed in which a parallelogram wire mesh is formed and this wire mesh is stretched around a frame having a similar shape.

  However, in the lattice metal mesh described in Patent Document 1, if a force is applied from the outside at the intersection of the vertical and horizontal wires, the horizontal line may move in the vertical direction with respect to the vertical line, and the inclination angle is inclined. If the angle of the horizontal line is changed to match the horizontal line, it is necessary to make the wave undulation of the horizontal line moderate to some extent.Therefore, the holding force of the vertical line by the horizontal line may decrease and the vertical line may move in the left and right direction. In the case of installation on a slope, there is a risk that the lattice shape will be deformed. Further, in the inclined wire mesh fence described in Patent Document 2, when a force is applied from the outside, the vertical wire moves in the left-right direction with respect to the horizontal wire, and the lattice shape may be deformed.

  The present invention solves the problems as described above, and at the intersection of the grid body, the intersection angle between the vertical wire and the horizontal wire is connected so as to be changeable, and the intersection is less likely to be displaced from each other. It is intended to provide a body and a fence using the lattice body.

In order to achieve the above object, the present invention is configured as follows.
That is, the lattice body according to the present invention includes a first wire and a second wire connected in a lattice shape at the intersection, and at each intersection, the first wire has a winding core on the lattice body. A coil portion is formed in the front-rear direction of the surface portion, and the shaft core portion formed on the second wire is loosely inserted into the hollow of the coil portion, and the first wire and the second wire The crossing angle can be changed.

  In the grid body according to the present invention, the coil portion of the first wire is formed by winding the first wire twice or more, and the inner diameter of the coil portion is the outer diameter of the shaft core portion of the second wire. It is good also as a structure made into 2 times or less.

  Moreover, the fence which concerns on this invention is characterized by the grid body of Claim 1 or 2 being supported between the support | pillars standing at intervals on the ground.

  According to the lattice body according to the present invention, the first wire rod and the second wire rod connected in a lattice shape at the intersecting portion, and at each intersecting portion, the first wire rod has a winding core on the lattice. A coil portion formed in the front-rear direction of the body surface portion is formed, and an axial core portion formed on the second wire is loosely inserted into the hollow of the coil portion, and the first wire and the second wire The crossing angle of the grid body can be changed, so that at each crossing portion, the connection between the first wire and the second wire is difficult to be removed, and the lattice shape of the lattice body is an arbitrary shape such as a rectangular shape or a parallelogram shape. It can be changed to a square shape.

  The coil portion of the first wire is formed by winding the first wire twice or more, and the inner diameter of the coil portion is less than twice the outer diameter of the shaft core portion of the second wire. Then, the coil portion of the first wire rod becomes difficult to move beyond the end portion of the shaft core portion of the second wire rod, and therefore the movement range of the coil portion is restricted within the front-rear width of the shaft core portion. Can do.

  According to the fence according to the present invention, since the lattice body is supported between the pillars erected on the ground at intervals, the lattice body is arranged so as to follow the undulations on the ground when the fence is installed. The lattice shape can be changed to a rectangular shape, a parallelogram shape, or the like.

It is the schematic which shows 3rd Embodiment in the fence which concerns on this invention. It is an expanded sectional view which shows the deformation | transformation of FIG.

  Next, the best mode for carrying out the present invention will be specifically described with reference to the drawings.

  In the drawings, 1 is a support column, 2 is a lattice body supported by the support column 1, and the fence P according to the present invention is mainly composed of the support column 1 and the lattice body 2.

  FIG. 1 is an explanatory view showing a first embodiment of a fence P according to the present invention, wherein (a) is a schematic front view, and (b) is an AA enlarged end view. The strut 1 is generally a square pipe-shaped steel pipe that is stable in strength and low in cost, but may be a round pipe-shaped steel pipe, such as a H-shaped, T-shaped, or hat-shaped steel material. It may be a support made of. Further, it may be formed from other metals such as stainless alloy and aluminum alloy. The struts 1 are erected at intervals and support the lattice body 2 between the struts 1.

  In the lattice body 2, the first wire 3 and the second wire 4 are arranged at intervals, and are connected in a lattice form at each intersection 21 between the first wire 3 and the second wire 4. Yes. The grid body 2 is arranged along the undulations on the ground, and the grid shape is rectangular when the ground is horizontal, and the grid shape is parallel four sides along the ground slope when the ground is inclined. It is made into a shape. In this embodiment, the 1st wire 3 is bent by the inclination change part T according to the undulation on the ground, and the 2nd wire 4 on the ground is arrange | positioned substantially perpendicularly irrespective of the undulation on the ground.

  In the present embodiment, the lattice body 2 is fixed to the support column 1 via a fixing member 5 as shown in FIG. The support column 1 is provided with a fixing hole 11 penetrating in the front-rear direction. The fixing member 5 is a rod-like body 53 in which a male screw part 51 is formed on one side and a J-shaped hook part 52 is formed on the other side. The rod-like body 53 penetrates the connection hole 11 of the support column 1 in the front-rear direction, the first wire 3 of the lattice body 2 is locked to the hook portion 52, and the nut N is fastened to the male screw portion 51. The lattice body 2 is fixed to the support column 1.

  2A and 2B are explanatory views of the lattice body 2 of FIG. 1, wherein FIG. 2A is a partially enlarged front view, FIG. 2B is a BB cross-sectional view, and FIG. 2C is a CC cross-sectional view. In each crossing portion 21 of the lattice portion 2, the first wire 3 is formed with coil portions 32 with the winding core 31 in the front-rear direction of the surface portion of the lattice body 2 at intervals. The second wire 4 is provided with an axial portion 41 that is loosely inserted into the hollow 33 of the coil portion 32. Thereby, in each cross | intersection part 21, it becomes possible to change a crossing angle arbitrarily, without the crossing position of the 1st wire 3 and the 2nd wire 4 shifting. Then, the shape of the grid body 2 can be reversibly changed to a rectangular shape or a parallelogram shape, and the grid body 2 can be arranged in accordance with the undulations on the ground as shown in FIG.

  In the present embodiment, the first wire 3 is wound around the core 31 from the front to the back as shown in (b) to form a coil portion 32, and another winding is again spaced apart. The configuration in which the coil portion 32 is formed by winding the core 31 from the front to the back is repeated. As a result, when the first wire rod 3 is wound and the coil portion 32 is sequentially formed at intervals, the first wire rod 3 and the adjacent coil portion 32 are unlikely to interfere with each other. Since manufacture becomes easy, it is preferable.

  Although not illustrated in the first wire rod 3 as another embodiment, the coil portion 32 is formed by winding from the front to the back with respect to the core 31, and is separated again at intervals. The coil 31 may be formed by winding the core 31 from the back to the front, and this configuration may be repeated.

  In the first wire 3, the number of turns of the coil portion 32 is two. Thereby, since the coil part 32 is not long in the direction of the winding core 31, the coil part 32 hardly crosses the front end part 42 and the rear end part 43 of the axial part 41 in the crossing part 21 of the lattice body 2, and the second It is preferable that the first wire 3 and the second wire 4 are less likely to move along the wire 4 and the crossing position between the first wire 3 and the second wire 4 is more difficult to shift. The number of turns of the coil portion 32 is not particularly limited. However, if the number of turns is extremely large, the length of the shaft core portion 41 is increased according to the length of the coil portion 32, and thus the second wire 4 When a tensile force is applied in the longitudinal direction, the moment generated at the front and rear end portions of the shaft core portion 41 becomes large, and there is a possibility that the shaft core portion 41 may be deformed to rise. Therefore, the number of turns of the coil portion 32 is preferably 1 to 5 turns, and more preferably 1 to 3 turns.

  In the present embodiment, the second wire 4 is formed by repeating a configuration that extends obliquely upward and rearward from the front end portion of the linear shaft core portion 41 and reaches the rear end portion of the adjacent shaft core portion 41. It is a thing. As a result, the angle formed by the second wire at the front end portion and the rear end portion of the shaft core portion 41 is smaller than 90 degrees. It is preferable that the front end portion and the rear end portion are not further crossed, and the crossing position of the first wire 3 and the second wire 4 is more difficult to shift.

  Although not shown in the second wire 4 as another embodiment, the second wire 4 extends upward from the front end portion 42 of the shaft core portion 41 and is adjacent to the front end portion 42 of the shaft core portion 41 adjacent on the upper side. And the rear end portion 43 extending upward from the rear end portion 43 of the shaft core portion 41 to reach the rear end portion 43 of the adjacent shaft core portion 41 on the upper side. .

  3A and 3B show still another embodiment, in which FIG. 3A is an enlarged front view of the intersecting portion 21 of the lattice body 2, and FIG. 3B is an enlarged side view of the intersecting portion 21. In the present embodiment, the second wire rod 4 is bent, and the tip portion of the second wire rod 4 is folded back so that the second wire rod 4 is overlapped and protruded to form the shaft core portion 41 of the coil portion 32 of the first wire rod 3. The hollow 33 may be loosely inserted, the distal end of the loose insertion may be bent and engaged with the coil portion 32, and the shaft core portion 41 may not be pulled out of the coil portion 32.

  The coil portions 32 of the first wire 3 are each formed with the winding core 31 in parallel, and the shaft core portions 41 of the second wire 4 are also provided in parallel. Thereby, since the crossing angle of the 1st wire 3 and the 2nd wire 4 can be changed smoothly, the deformation | transformation operation | work which deform | transforms the lattice shape of the lattice body 2 becomes easy.

  In the present embodiment, the second wire 4 is juxtaposed in the vertical direction, and the first wire 3 is juxtaposed with the second wire 4, but the first wire 3 is in the vertical direction. The second wire 4 may be arranged in parallel with the first wire 3 in parallel.

  The first wire 3 and the second wire 4 are generally produced by cutting a metal wire into an appropriate length, and steel, aluminum alloy, stainless alloy, or plating on the surface thereof. Those that have been applied, those that have been painted, or resin fibers such as polypropylene, polyester, and nylon are used.

  4A and 4B are explanatory views showing a second embodiment of the lattice body 2 according to the present invention, wherein FIG. 4A is a front view, FIG. 4B is a DD cross-sectional view, and FIG. 4C is an EE cross-sectional view. It is. Compared with the grid body 2 shown in FIGS. 1 and 2, the grid body 2 according to the present embodiment includes the form of the coil portion 32 of the first wire rod 3 and the second wire rod 4 adjacent in the left-right direction. The main difference is that they are arranged in the reverse direction, and the other parts have the same configuration.

  That is, at the intersection 21 adjacent to the left and right, one of the front end portions 42 of the shaft core portion 41 of the second wire rod 4 loosely inserted into the hollow 33 of the coil portion 32 is extended upward, and the other is downward. The rear end portion 43 of the shaft core portion 41 extends in the opposite direction.

  Thereby, in the intersection part 21 adjacent to right and left, both the coil parts 32 are prevented from moving along the second wire 4 beyond the front end part 42 or the rear end part 43 of the shaft core part 41. It is possible to prevent the positional deviation of the intersecting portion 21 of the lattice body 2. Further, as shown in FIG. 4, even when the number of turns of the coil portion 32 is one, as described above, it is possible to prevent the positional deviation of the intersecting portion 21 of the lattice body 2.

  That is, as shown in FIG. 6, coil portions 32 in which the core 31 is parallel are formed at both ends of the first wire 3. The coil portion 32 is wound with a gap 35 between the windings 34. As a result, in the two first wire rods 3, the integral coil portion 32 is formed in which the winding 34 of one coil portion 32 is inserted and connected to the gap 35 of the other coil portion 32. The lattice body 2 can be formed by loosely inserting the shaft core portion 41 of the second wire 4 into the hollow 33 of the coil portion 32.

  The dimensional relationship between the gap 35 of the coil part 32 and the winding 34 is not particularly limited. For example, as shown in FIG. 5, if the first wire rods 3 formed with the coil portions 32 in which the width R2 of the gap 35 is wider than the outer diameter R1 of the winding 34 are connected in the same manner as described above, the coil portions The crossing angle of the first wire 3 can be changed with respect to the second wire 4 provided with the shaft core portion 41 loosely inserted into the 32 hollows 33. Thereby, when installing the fence P in an inclined ground, since the 2nd wire 4 can be used as an inclination change part, as shown in FIG. 1, the 1st wire 3 is bent each time in an inclination change part, as shown in FIG. There is no need, and the construction work becomes easier.

  Although not shown, the width R2 of the gap 35 between the windings 34 is made narrower than the outer diameter R1 of the winding 34 of the coil part 32, and the winding 34 of the coil part 32 is pressed into the gap 35 for insertion. If it does, coil parts 32 can be connected firmly.
