The trunk edge 43 is bolted to the support flange 21 (31) through the hole 43c.

  An interval between the trunk flange 43a and the claw portion 43b is an interval at which the reinforcing member 42 can be gripped. The reinforcing material 42 pierced by the rhombus metal mesh 41 is gripped at this interval, so that the panel 4 is formed.

  Thus, when the panel 4 is comprised so that it can expand-contract vertically, it can shrink | contract compactly when conveying the manufactured panel 4 from a manufacturing place to a construction site. In the conventional wire mesh fence, the transportability was poor because the panel was transported to the construction site in the unfolded state, but the wire mesh fence 1 according to the present embodiment can contract the panel 4 in this way. It has excellent transportability to the site.

  In addition, as described above, the wire mesh pieces 410a and 410b constituting the panel 4 are slidable in the left-right direction, so that the wire mesh fence 1 can be installed on an inclined ground.

  Next, the construction method of the wire fence 1 using the above-mentioned end column 2, intermediate column 3, and panel 4 will be described.

  First, the end struts 2, the intermediate struts 3, and the panels 4 that are constituent members of the wire mesh fence 1 are transported from the manufacturing site or storage location to the construction site. At this time, since the panel 4 is transported in a contracted state, it is easy to carry.

  Next, a plurality of end columns 2 and at least one intermediate column 3 are erected at predetermined intervals on the construction site. The end support columns 2 are erected so as to be positioned at both ends in the longitudinal direction of the wire mesh fence 1 when the construction of the wire mesh fence 1 is completed. The number of intermediate struts 3 is adjusted according to the length of the wire mesh fence 1.

  Next, the panel 4 transported to the construction site in a contracted state is developed at the construction site.

  Next, the two metal mesh pieces 410a and 410b of the developed panel 4 are slid according to the inclination of the installation location of the metal mesh fence as necessary. If the installation location of the wire mesh fence 1 is flat, this sliding operation is not necessary.

  Next, the panel 4 which is unfolded and the metal mesh pieces 410a and 410b are slid as necessary is temporarily placed between the end column 2 and the intermediate column 3 and between the intermediate column 3 and the intermediate column 3. That is, it is temporarily positioned without bolt fastening. The temporary placement of the panel 4 is performed as follows.

  FIG. 10 is a partial perspective view showing a state in which the panel 4 is temporarily placed on the column 2. FIG. 11 is a side sectional view showing a state in which the panel 4 is temporarily placed on the column 2 (3). The panel 4 on which the metal mesh pieces 410a and 410b are slid as needed is placed on the column flange 21 of the end column 2 and the column flange 31 of the intermediate column 3 to be temporarily placed.

  Specifically, two adjacent two gaps are formed in the gap formed between the trunk edge flange 43a located on the upper side (+ Z direction) of the panel 4, the rhombus metal mesh 41, and the reinforcing material 42 pierced therewith. By inserting the upper end of the column flange 21 (31) of the column 2 (3), the upper side of the panel 4 is positioned, and the panel 4 is temporarily placed.

  At this time, the trunk edge flange 43a located on the upper side of the panel 4 attached to the column 2 (3) and the trunk edge flange 43a located on the lower side are respectively in the Y direction across the column flange 21 (31). It will be in the state located on the opposite side.

  When the panel 4 is temporarily placed on the support 2 (3), as shown in FIG. 15, the hole 421 of the reinforcing member 42, the hole 22 (32) of the support flange 21 (31), and the hole 43c of the trunk flange 43a. In the XZ plane are aligned. These holes 421, 22 (32), 43c have the same diameter into which the bolt 7 can be inserted.

  As described above, in the wire mesh fence 1 according to the present embodiment, the panel 4 can be temporarily placed on the support column 2 (3) before the bolt is tightened, so the panel 4 is bolted to the support column 2 (3). At this time, it is not necessary for the worker to lift the panel 4, and even one worker can easily perform the installation. Therefore, compared with the conventional wire mesh fence, the wire mesh fence 1 which concerns on this embodiment is the thing excellent in the workability | operativity at the time of the installation.

  Next, the panel 4 temporarily placed in this manner is bolted to the column flange 21 (31) using bolts 7 and nuts 8, whereby the panel 4 is fixed to the column 2 (3). At this time, as shown in FIG. 15, the bolt 7 is inserted through the hole 421 of the reinforcing member 42, the hole 22 (32) of the support flange 21 (31), and the hole 43c of the trunk flange 43a. , By fixing with the nut 8.

  Thus, in a state where the panel 4 is attached to the support column 2 (3), the upper flange flange 43a is located on the opposite side of the surface of the support flange 21 (31) that faces the rhombus metal mesh 41 (wire mesh fence). 1 is in contact with the surface facing the rhombus metal mesh 41 of the support flange 21 (31) (the back side of the metal mesh fence 1). ing.

  Further, in the state where the trunk flange 43a and the reinforcing member 42 are only bolted to the support flange 21 (31), the left and right ends in the X direction of the rhombus metal mesh 41 are the intermediate portions in the Z direction of the support flange 21 (31). ) Is not fixed. Therefore, the rhombus metal mesh 41 can be lifted from the support flange 21 (31).

  Therefore, the rhombus wire mesh 41 is fixed to the support flange 21 (31).

  FIGS. 12A and 12B show a state in which the panel 4 is attached to the end column 2, (A) is an upper enlarged rear view, (B) is an upper enlarged side view, (C) is a lower enlarged rear view, and (D). FIG.

  14A and 14B show a state in which the panel 4 is attached to the intermediate support column 3. FIG. 14A is an enlarged rear view of the central portion, and FIG. 14B is an enlarged plan view of the central portion.

  The rhombus wire mesh 41 is fixed to the support flange 21 (31) by firstly attaching the vertical member 5 to the two support posts 2 (3) along the opposite ends in the Y direction (along the ± Z directions). This is done by piercing the wire mesh 41.

  The vertical member 5 pierced by the rhombus wire mesh 41 is first bolted to the column flange 21 (31) via the bolt 7 and the nut 8 at the upper and lower ends.

  For this bolt fastening, a horizontally long hole 22 (32) provided at the uppermost part of the support flange 21 (31) is used. The vertical member 5 is fixed in the Z direction by the bolt fastening at this time, but is not yet fixed in the X direction.

  Next, the vertical member 5 is fixed to the support flange 21 (31) in the X direction via a plurality of hook bolts 81 and nuts 82.

  The hook bolt 81 is a member formed by bending a steel rod into a J shape, and a thread that can be screwed into the nut 82 is formed at one end.

  In the bolt fastening with the hook bolt 81 and the nut 82, the degree of advancement / retraction of the hook bolt 81 with respect to the support flange 21 (31) can be adjusted.

  When the metal mesh pieces 410a and 410b of the panel 4 slide in the left-right direction and the left and right ends of the metal mesh pieces 410a and 410b are not straight, the vertical material 5 is inserted into these ends. The state is not perpendicular to the Z direction. Therefore, even in such a case, the vertical member 5 can be fixed in the X direction by adjusting the forward and backward movement of the hook bolt 81 according to the inclination of the vertical member 5.

  FIG. 16 is a rear view showing the wire mesh fence 1 provided on the sloping ground in a state where the wire mesh pieces 410a and 410b slide in the left-right direction.

  In this way, the rhombus metal mesh 41 through which the vertical member 5 is pierced is fixed to the support flange 21 (31), and the rhombus metal mesh 41 does not float from the support flange 21 (31).

  According to the wire mesh fence 1 which concerns on this embodiment mentioned above, when conveying each member which comprises this to a construction site, since the panel 4 can be conveyed in the contracted state, the outstanding transportability is exhibited. Moreover, since the panel 4 can be temporarily placed with respect to the support | pillar 2 (3) at the time of construction in a construction site, the installation operation | work of the wire-mesh fence 1 becomes easy and exhibits outstanding workability.

  Moreover, according to the wire mesh fence 1 which concerns on this Embodiment 1, the two wire mesh pieces 410a and 410b of the panel 4 can be slid to right and left. Therefore, even when the end support column 2 and the intermediate support column 3 are vertically installed on the inclined land, the panel 4 can be attached between the support columns 2 and 3, and the wire mesh fence 1 can be installed on the inclined land. It becomes possible.

  In the above-described embodiment, the number of wire mesh pieces constituting the panel is two. However, the present invention is not limited to this, and the number of wire mesh pieces is adjusted according to the inclination of the ground on which the wire mesh fence is provided. Can do.

  FIG. 17 is a rear view showing a wire mesh fence 1 ′ configured using a panel 4 ′ having three wire mesh pieces 410 a, 410 b and 410 c.

  Unlike the above-described wire mesh fence 1, the wire mesh fence 1 ′ shown in FIG. 17 uses a panel 4 ′ configured using three wire mesh pieces 410a, 410b, and 410c as a wire mesh piece that can slide to the left and right. Others have the same configuration as the wire mesh fence 1 described above. The overall height of the panel 4 ′ and the panel 4 is the same, but the height of the wire mesh pieces is different, and the height of the wire mesh pieces 410a, 410b, 410c in the panel 4 ′ is the total height of the panel 4 ′. It is about 1/3 of.

  The wire mesh piece 410a and the wire mesh piece 410b, and the wire mesh piece 410b and the wire mesh piece 410c are slidably connected to the left and right as the connecting wire 413 is pierced. The connection using the connecting wire 413 is performed in the same manner as the connection between the wire mesh piece 410a and the wire mesh piece 410b of the wire mesh fence 1 described above.

  FIG. 18 is a rear view showing the panel 4 ′ in a state where the three metal mesh pieces 410 a, 410 b, 410 c slide to the left and right.

  The panel 4 ′ is composed of three wire mesh pieces 410a, 410b, 410c, although the overall height is not different from the panel 4 as described above, and is formed at two places between the wire mesh pieces 410a-410b and between the wire mesh pieces 410b-410c. It can slide left and right. Therefore, compared with the panel 4 that can be slid left and right at only one place, the slidable distance to the left and right is doubled.

The overall height of the panel 4 ″ is the same as the above-described panel 4 and panel 4 ′, and the height of the six metal mesh pieces 410a, 410b, 410c, 410d, 410e, 410f is that of the panel 4 and the panel 4 ′, respectively. It is lower than the one.

  The metal mesh pieces 410a and 410b, the metal mesh pieces 410b and 410c, the metal mesh pieces 410c and 410d, the metal mesh pieces 410d and 410e, and the metal mesh pieces 410e and 410f are slidably connected to each other by the connecting wire 413. .

  FIG. 21 is a rear view showing a state in which the six metal mesh pieces 410a, 410b, 410c, 410d, 410e, and 410f of the panel 4 ″ of FIG. 20 are slid left and right.

  The panel 4 ″ is composed of six wire mesh pieces 410a, 410b, 410c, 410d, 410e, 410f, although the overall height is not changed from the panel 4, 4 ′ as described above, and between the wire mesh pieces 410a-410b, the wire mesh pieces. 410b-410c, between the metal mesh pieces 410c-410d, between the metal mesh pieces 410d-410e, and between the metal mesh pieces 410e-410f are slidable to the left and right.

  Therefore, the panel 4 ″ has a slidable distance to the left and right five times that of the panel 4 slidable to the left and right at only one place.

  FIG. 22 is a rear view showing the wire mesh fence 1 ″ in a state where the six wire mesh pieces 410 a, 410 b, 410 c, 410 d, 410 e, 410 f slide to the left and right. As shown in FIG. 22, the wire mesh fence 1 ″ can cope with a steeper slope than the wire mesh fence 1 shown in FIG. 16 or the wire mesh fence 1 ′ shown in FIG. 19.

  In the above-described embodiment, the L-type steel material is used as the end column 2 and the T-type steel material is used as the intermediate column 3, but in the present invention, the panel 4 side is used for temporarily placing and fixing the panel 4. Any column having a column flange projecting from the column can be preferably used. Therefore, for example, a hat-shaped steel material having two flanges as a support can be used.
