It may be formed.

  The core member 6 has an oval shape that is long in the front-rear direction. For example, as shown in FIG. 5, in this embodiment, in the state where the first core member 61 and the second core member 62 having the same diameter and the same size divided into two parts are screwed in the front-rear direction, It has an oval shape that is long in the direction. By forming the core material 6 in the shape of an ellipse that is long in the front-rear direction, the core material 6 rotates even when the net-shaped member 2 is pulled by an external force such as wind pressure, so that the net-shaped member 2 is The escape from the frame member 3 is suppressed.

  In the present embodiment, the core member 6 is formed by screwing a member divided into two parts. However, the core member 6 is not particularly limited to this form. For example, it is integrally formed in the front-rear direction by extrusion molding of an aluminum alloy. The core material 6 having a long oval shape may be formed, or may be formed using a member divided into three or more parts.

  The decorative member 5 is attached to the vertical frame material body 31 of the vertical frame material 3 so that the core material 6 accommodated in the storage part 33 of the vertical frame material body 31 is concealed from the outside. Further, the front surface 35 and the back surface 36 of the vertical frame member 3 are symmetric with the decorative member 5 attached to the vertical frame member main body 31.

Is done.

  Next, a method for holding the end 21 of the net-like member 2 will be described in detail. First, the end 21 of the net-like member 2 is sandwiched between the first core member 61 and the second core member 62 using a screw such as a tapping screw B to The core member 61 and the second core member 62 and the net-like member 2 sandwiched between the core member 61 and the net-like member 2 are screwed in the front-rear direction, and sandwiched between the first core member 61 and the second core member 62. The net-shaped member 2 is integrated with the end portion 21 of the net-shaped member 2 wound around the outer periphery of the core member 6 around the outer periphery of the core member 6. The core member 6 around which the end portion 21 of the cylindrical member 2 is wound is accommodated, and the pressing bolt 7 which is the pressing member is provided in the two concave portions 63 formed at positions facing each other in the left-right direction of the core member 6. And the protruding portion 341 of the protruding portion 34 are inserted, and the push bolt 7 and the protruding portion 341 of the protruding portion 34 are inserted. With an end portion 21 of the net-like member 2 by the the core material 6 is sandwiched, it said core material 6 is fixed to the vertical frame member main body 31. Thereafter, the decorative member 5 is attached to the front side surface of the vertical frame material body 31 to form the vertical frame material 3.

  Next, a method for stretching the net-like member 2 will be described. As shown in FIG. 2, first, the vertical frame member 3 holding the end portion 21 of the net-like member 2 is attached to the support column 1 via the extending portion 32 and the extending bolt 4. Next, when the nut A attached to the tension bolt 4 is tightened and the tension portion 32 is moved to the column 1 side, the vertical frame member 3 is also moved to the column 1 side in conjunction with it. Thereby, the said net-like member 2 is stretched in the left-right direction.

  In another embodiment of the windproof snow fence according to the present invention shown in FIG. 9, the vertical frame member 3 on which the end 21 of the net-like member 2 is held is passed through the extension part 32 and the extension bolt 4. The nut A attached to the tension bolt 4 is not in direct contact with the tension portion 32, and a coil spring D is inserted therebetween. By inserting the coil spring D, when the nut A is tightened, the tension of the net-like member 2 can be managed by measuring the amount by which the coil spring D contracts. Furthermore, after the windbreak snow fence P is installed, when the nut A is loosened for some reason, the coil spring D can be extended and the tension state of the net-like member 2 can be maintained.

  The end portion 21 of the net-like member 2 is in pressure contact with the push bolt 7, the protruding portion 34, and the core member 6 in the housing portion 33. The end portion 21 of the net-like member 2 is pushed by the frictional force generated between the end portion 21 of the net-like member 2, the push bolt 7, the convex portion 341 of the projecting portion 34, and the core member 6. The bolt 7, the projecting portion 34, and the core material 6 are sandwiched. With this structure, even when the end portion 21 of the net-like member 2 is pulled with a force exceeding the frictional force, the entire end portion 21 of the net-like member 2 is not easily pulled out of the accommodating portion 33. That is, since it is not necessary to hold the end 21 of the net-like member 2 during the tensioning operation, the workability of the tensioning work can be improved.

  In general, when the net-like member 2 is stretched, the net-like member 2 is relatively easy to loosen due to the weight of the net-like member 2 or the attachment of snow or the like. The plate-like portion of the column 1 can be adjusted so that the tension of the net-like member 2 can be adjusted, for example, when the net-like member 2 is tightly stretched or when the slackening of the net-like member 2 is relieved. More preferably, a plurality of the tension bolts 4 are attached to the vertical direction 12, and a plurality of the tension portions 32 are attached to the tension bolts 4.

  In the present embodiment, the tension bolt 4 has a head portion 42 disposed on the column 1 side, a screw portion 41 passing through the tension portion 32, and a nut A attached to the tip of the screw portion 41. The net-like member 2 stretched around the column 1 and the tightening nut A are arranged on the same side surface side. As a result, it is possible to easily check the tension of the net-like member 2 while tightening the nut A. Therefore, it is easier to adjust the tension of the net-like member 2 and so on. The workability can be improved.

  Further, when the net-like member 2 is stretched on both side surfaces of the support column 1, as shown in FIG. 6, as the extension bolt 4, a screw portion 41 provided on both sides is attached to the support column 1. The extension portion 32 may be fixed to both screw portions 41, or the extension portion may be attached to the extension bolt 4 attached in the opposite direction above and below the plate-like portion 12 of the support column 1. 32 may be attached. In any case, it is preferable because the mounting position in the front-rear direction of the net-like member 2 stretched on both sides across the support column 1 can be adjusted.

  The net-like member 2 is not particularly limited to a net as long as the end 21 thereof is flexible enough to be accommodated in the accommodating portion 33 of the vertical frame member 3, and is not limited to a net, but is a cloth-like one, synthetic resin A suitable sheet may be used, such as a sheet-like sheet made of plastic or a sheet obtained by punching a flexible sheet. For example, high-strength stretched polyolefin tape, polyester fiber, etc. are used as the core material, and the core material is woven in a net shape and coated with EVA, vinyl chloride resin, acrylic resin, etc., or the core material previously coated with resin is woven in a net shape If a net or the like formed by heat-sealing the intersection is used, the net-like member 2 is less likely to be decomposed and has little possibility of slacking of the net over a long period with little elongation due to wind pressure. Can be obtained.

  If the opening ratio of the net-like member 2 is 50% or more, it is difficult to obtain the effect of windproof snow. If it is in the range of 0 to 50%, a sufficient effect as a windproof snow fence is obtained, but the opening ratio is too low. And road users can not get a view of the surroundings, and also feel a sense of pressure and blockage, so the opening ratio of 30-50% is to balance the effect of windbreaking snow and securing the surrounding view and lighting. preferable. In addition, the color tone of the net-like member 2 is not particularly limited and may be an appropriate color tone. However, the tone of the net-like member 2 can be harmonized with the surrounding scenery, and good outside the windbreak snow fence from an oblique direction. It is preferable that the color tone is gray, black, or a color close to it so that a view can be obtained.

  If the support column 1 has an H-shaped cross section as in this embodiment, when the net-like member 2 is stretched, the vertical frame member 3 and a part of the stretched portion 32 are placed inside the support column 1. Since it can be arranged, it is preferable because it can conceal the gap between the support column 1 and the vertical frame member 3 when viewed from the front side of the windproof snow fence P and improve the appearance, but is not limited to this embodiment. A round pipe, a square pipe, or the like can be used as appropriate.

  In consideration of supporting the net-like member 2 to which a large wind pressure is applied, the vertical frame member 3 is preferably a metal member, and is generally a long pipe made of aluminum, stainless steel, steel, or the like. What cut | disconnected the body to length suitably, what gave them plating and coating, etc. can be used suitably. Similarly, it is preferable to use a metal material for the extending portion 32, and a pipe, a plate-like body, a profile, and various angle materials can be used.

  Similarly, it is preferable to use a metal material for the core material 6 as well, and it is possible to use a material obtained by cutting a long body made of a pipe or a shape material into an appropriate length.

  In the above-described embodiment according to the present invention, the net-like member 2 is stretched in the left-right direction between the struts 1. When it is easier to install the net-like member 2 in the up-down direction, such as when the interval is set relatively narrow, or when the net-like member 2 can be more stably stretched, the net-like member 2 is arranged in the up-down direction. It may be stretched. In this case, a horizontal member is attached vertically between the support columns 1, a vertical frame member 3 is attached to the horizontal member, and the net-like member 2 is vertically moved between the horizontal members via the vertical frame member 3. It may be stretched. In addition, a rectangular frame is attached between the columns 1, and vertical frame members 3 are respectively attached to the upper and lower portions of the frame, and the net-like member 2 is stretched in the vertical direction via the vertical frame member 3. You may set up.
