発明が解決しようとする課題Problems to be solved by the invention

しかしながら、上記従来の支柱は、屋外に立設されているために吊り張りされたネットが風の影響を受け易く、従来の円筒形状の支柱、特に下部支柱体はネットの吊り張り方向に対して垂直な方向を補強すべく幅広のプレートを吊り張り方向と並行になるように下部支柱体に取り付ける必要がありその取り付け作業が煩雑であるとともに、穿孔する孔の径も大きくする必要があった。However, since the above-mentioned conventional column is erected outdoors, the suspended net is easily affected by the wind, and the conventional cylindrical column, especially the lower column, is in the direction of the net tension. In order to reinforce the vertical direction, it is necessary to attach a wide plate to the lower column so as to be parallel to the suspending direction, and the installation work is complicated, and the diameter of the hole to be drilled must be increased.

また、円筒形状の支柱は、上部支柱体に連結具を介して直接又は滑車を介して移動するロープに間接的にネットを取り付けるが、連結具の取り付けが球面への取り付けとなり、その取り付け作業効率が煩雑であるという欠点があった。In addition, a cylindrical column has a net attached to a rope that moves directly or via a pulley to the upper column body, but the attachment of the connector is attached to a spherical surface, and the installation work efficiency However, there was a drawback that it was complicated.

また、上部支柱体が円筒形状に形成され上部支柱体の半面で風の影響を直接受けるために、ネットの吊り張りする面積及び風の影響を考え径を拡大する等の強度を補強しなければならない。In addition, since the upper support body is formed in a cylindrical shape and is directly affected by the wind on the half of the upper support body, it is necessary to reinforce the strength such as expanding the diameter considering the area of the net suspended and the influence of the wind. Don't be.

さらに、風の影響を受けたネットが上部支柱体に絡みつくために、ネットの摩耗が激しいという問題点があった。Furthermore, since the net affected by the wind is entangled with the upper support body, there is a problem that the net wears heavily.

そこで、本発明は上記課題を解決すべく、風の影響を受けにくく、支柱の立設時での強度があり、ネットの取り付けが容易なネット用の支柱の立設方法を提供することを課題とする。Therefore, in order to solve the above-mentioned problems, the present invention provides a method for erecting a support for a net that is not easily affected by wind, has strength at the time of erecting a support, and is easy to attach a net. And

上記課題を解決する本発明の解決手段としてのネット用支柱の立設方法は、請求項１に記載のように、屋外空間部の外側に沿ってネットの吊り張りするために所望の間隔で孔を穿孔した後、下部支柱体を地中に埋設して支柱を立設するネット用の支柱の立儲方法において、前記下部支柱体の断面形状を三角形状又は多角形状に形成し、ネット吊り張り方法に対して該下部支柱体の一方の角が垂直方向となるように孔に埋設するとともに、前記上部支柱体の断面形状を前記下部支柱体と同一又は相違する三角形状又は多角形状に形成し、ネットの吊り張り方向に対して該上部支柱体の一方の角が垂直方向となるように立設することを特徴とする。Standing設方method net for posts as solving means of the present invention to solve the above problems, as described in claim 1, holes at desired intervals to the hanging tension of the net along the outside of the outdoor space In the method of standing up a net support, the lower support body is buried in the ground and the support post is erected, the cross-sectional shape of the lower support body is formed in a triangular shape or a polygonal shape, The method is to be embedded in a hole so that one corner of the lower support column is perpendicular to the method, and the cross-sectional shape of the upper support column is the same or different from that of the lower support column. Further, the present invention is characterized in that it is erected so that one corner of the upper support column is perpendicular to the direction in which the net is suspended.

発明の作用効果Effects of the invention

本発明のネット用の支柱の立設方法の作用効果について説明する。The operation and effect of the net post support method of the present invention will be described.

また、ネットの吊り張りに沿って上部支柱体の対角線を垂直方向に設置することで、ネットの風方向に自在に対応して強度を保った状態で使用できる。Moreover, by installing the diagonal line of the upper support body in the vertical direction along the suspension of the net, it can be used in a state where the strength is maintained corresponding to the wind direction of the net.

次に、請求項２に記載のネット用の支柱の立設方法は、先ず屋外空間部の外周に沿って所望の間隔で孔を穿設した後、該孔に下部支柱体を挿入して埋設することで、地上部分に上部支柱体を立設する。Next, according to the method for erecting a support for a net according to claim 2, first, holes are drilled at desired intervals along the outer periphery of the outdoor space portion, and then a lower support body is inserted into the hole and embedded. By doing so, the upper support body is erected on the ground part.

その後、前記上部支柱体それぞれに直接又は間接的にネットを取り付けることで、屋外空間部の外周に沿ってネットを吊り張りすることができる。Thereafter, the net can be suspended along the outer periphery of the outdoor space by directly or indirectly attaching the net to each of the upper support columns.

この際、前記下部支柱を形成する下部支柱体の断面形状を三角形状又は多角形状に形成することで、該下部支柱体の一方の角を、ネットを吊り張り方向に対して垂直方向となるように埋設することで他方の角がネットの吊り張り方向に対して並行方向となり、ネットが受ける風方向に対し地中の面積を拡大することができ、より強固に支柱を立設することができる。At this time, by forming the cross-sectional shape of the lower support body forming the lower support structure into a triangular shape or a polygonal shape, one corner of the lower support body is perpendicular to the direction in which the net is suspended. By embedding in, the other corner becomes a parallel direction to the direction of the net suspension, the area under the ground can be expanded with respect to the wind direction received by the net, and the column can be erected more firmly .

また、前記上部支柱体の断面形状を下部支柱体と同一又は相違する三角形状又は多角形状に形成し、該上部支柱体の一方の角をネットの吊り張り方向に対して垂直方向となるように立設することで、ネットと上部支柱体の側面との接触面積を減少するとともに、ネットが受ける風の荷重を左右方向に流すことで、風の影響を軽減することができる。In addition, the cross-sectional shape of the upper support column is formed in a triangular or polygonal shape that is the same as or different from that of the lower support column, and one corner of the upper support member is perpendicular to the net hanging direction. By standing, the contact area between the net and the side surface of the upper column body can be reduced, and the influence of wind can be reduced by flowing the wind load received by the net in the left-right direction.

また、風の影響を受けたネットを一端側で支えることができ、上部支柱体にネットが絡みつくことがない。In addition, the net affected by the wind can be supported on one end side, and the net does not get entangled with the upper support body.

このように、本願発明のネット用の支柱の立設方法は、下部支柱体の断面形状を三角形状又は多角形状に形成することで、ネットの吊り張り方向に対して垂直方向に一方の角を一致させ強度を増した状態で立設でき、その立設工程が容易であり、また、少なくとも前記上部支柱体の断面形状を三角形状又は多角形状に形成することで、ネットの吊り張り方向に対して垂直方向に一方の角を一致させ風の抵抗を分散することができ、上部支柱体の強度を維持して安全に立設することができ、容易に支柱を立設することができる。As described above, in the method for erecting the support for a net according to the present invention, by forming the cross-sectional shape of the lower support body in a triangular shape or a polygonal shape, one corner is formed in a direction perpendicular to the direction in which the net is suspended. It can be erected in a state where it is matched and increased in strength, and its erection process is easy, and at least the cross-sectional shape of the upper support column is formed in a triangular or polygonal shape, so that Thus, one of the corners can be made to coincide with each other in the vertical direction, and the wind resistance can be dispersed. The strength of the upper column body can be maintained and the column can be erected safely, and the column can be erected easily.

次に、本発明のネット用の支柱の立設方法について図面を参照して説明する。Next, a method for erecting a net support according to the present invention will be described with reference to the drawings.

FIG. 4 is a schematic explanatory view showing a state in which the net is suspended in an arc shape, and FIGS. 5, 6 and 7 are other embodiments of the post for the net of the present invention. 8 is a schematic side view showing the support for the net shown in FIG. 7, and FIGS. 9 and 10 are schematic plan views showing other embodiments of the support for the net. FIG. 12 is a schematic side view showing the lower support body of FIG. 10, and FIG. 12 is a flowchart showing the net support method of the present invention.

本発明のネット用の支柱１は、地中に埋設する下部支柱体２と、地上部分に立設される上部支柱体３とから構成されている。The net support 1 according to the present invention includes a lower support 2 that is buried in the ground and an upper support 3 that is erected on the ground.

前記下部支柱体２は、断面形状が三角形状又は多角形状（実施例では正方形状）で、側面は下部側より上部側が幅狭に傾斜して形成され、該下部支柱体２の上端面に連続して一体的に上部支柱体３が取り付けられ、上部支柱体３の上端側にはネット取り付け用のロープを移動する滑車（図示せず）が取り付けられている。The lower support column 2 has a triangular or polygonal cross section (in the embodiment, a square shape), and the side surface is formed so that the upper side is inclined narrower than the lower side, and is continuous with the upper end surface of the lower support column 2. Thus, the upper support body 3 is integrally attached, and a pulley (not shown) for moving the rope for attaching the net is attached to the upper end side of the upper support body 3.

上記のように、本発明のネット用の支柱１は下部支柱体２と上部支柱体３とが一体的に形成されているが、本発明のネット用の支柱１の構成はこれに限定されるものでなく、下部支柱体２と上部支柱体３とを別体として構成することも可能である。As described above, in the net support 1 of the present invention, the lower support 2 and the upper support 3 are integrally formed, but the configuration of the net support 1 of the present invention is limited to this. It is also possible to configure the lower support body 2 and the upper support body 3 as separate bodies.

これにより、下部支柱体２の対角線Ａと上部支柱体３の対角線Ｂとを交差するように連結し、下部支柱体２と上部支柱体３とで強度をさらに補強することも可能であり、また、下部支柱体２と上部支柱体３の断面形状を相違させることで、風等の影響を自在に対応することができる。例えば、下部支柱体２の断面形状を五角形に形成し、上部支柱体３の断面形状を三角形状に形成することで、下部支柱体２の一方の角をネット４の吊り張り方向に対して垂直方向にするとともに、他の角をネットの吊り張り方向に対して並行方向にすることとなり、下部支柱体の埋設時の強度を維持でき、また、上部支柱体３は一方の角をネットの吊り張り方向に対して垂直方向に一致させることで、他の２つの角がネットの吊り張り方向に対して並行方向となり、風の流れを分散することができる。Thereby, it is possible to connect the diagonal line A of the lower column body 2 and the diagonal line B of the upper column body 3 so as to cross each other, and the lower column body 2 and the upper column body 3 can further reinforce the strength. By making the cross-sectional shapes of the lower support body 2 and the upper support body 3 different, the influence of wind or the like can be dealt with freely. For example, by forming the cross-sectional shape of the lower support column 2 into a pentagon and forming the cross-sectional shape of the upper support column 3 in a triangular shape, one corner of the lower support column 2 is perpendicular to the tension direction of the net 4. And the other corners are parallel to the suspension direction of the net, so that the strength when the lower support body is buried can be maintained, and the upper support body 3 has one corner suspended from the net. By making it coincide with the direction perpendicular to the tension direction, the other two corners are parallel to the net tension direction, and the wind flow can be dispersed.

また、上記ネット用の支柱１は下部支柱体２と上部支柱体３の断面形状を正方形に形成したが、本発明において、下部支柱体２と上部支柱体３との断面形状はこれに限定されるものでなく、長方形状、五角形状等に形成することも可能で、ネット４の高低に応じて受ける風の影響に対応して自在に選択することも可能である。In the above-described net support 1, the lower support 2 and the upper support 3 are formed in a square cross section. However, in the present invention, the cross sections of the lower support 2 and the upper support 3 are limited to this. It can be formed in a rectangular shape, a pentagonal shape, or the like, and can be freely selected according to the influence of the wind received according to the height of the net 4.

本発明のネット用の支柱１は上記のように構成され、次に該ネット用の支柱１を用いて屋外空間部の防球用ネット４を吊り張りするのに使用する場合について説明する。The net post 1 of the present invention is configured as described above, and the case where the net post 1 is used to suspend the ballproof net 4 in the outdoor space will be described next.

先ず、屋外空間部に設置するネット４の面積の大小、及びネット４を吊り張りする高さに応じてネット用の支柱１を選択する。First, the net support 1 is selected according to the size of the area of the net 4 installed in the outdoor space and the height at which the net 4 is suspended.

即ち、ネット４の面積が大きく、吊り張りする高さが高いと風の影響を受け易く、上部支柱体３の断面形状を三角形状、又は四角形状等少ない角に形成し、一方の角をネット４の吊り張り方向に対して垂直方向とすることで風を左右方向に分散でき、また、上部支柱体３と下部支柱体２との断面形状を相違する場合は、下部支柱体２を四角形等にすることで、下部支柱体２の埋設時の強度を強化することができる。That is, if the area of the net 4 is large and the suspended height is high, it is easily affected by the wind, and the cross-sectional shape of the upper support body 3 is formed in a small corner such as a triangle or a quadrangle, and one corner is formed on the net. 4 can be distributed in the left-right direction by making the direction perpendicular to the suspending direction of 4 and when the cross-sectional shapes of the upper column body 3 and the lower column body 2 are different, the lower column body 2 is rectangular or the like. By doing, the intensity | strength at the time of embedding the lower column body 2 can be strengthened.

また、下部支柱体２と上部支柱体３とを別体で形成した場合は、上部支柱体３を鋼管ポール等のコンクリート製より強度を有する材質で構成することで、さらに、強度を強化することができる。Moreover, when the lower column body 2 and the upper column body 3 are formed separately, the upper column body 3 is made of a material having a strength higher than that of concrete such as a steel pipe pole, thereby further strengthening the strength. Can do.

次に、上記のようにして選択したネット用の支柱１を立設する場合は、屋外空間部の外周に沿って所望の間隔で孔を穿孔し、該孔にネット用の支柱１の下部支柱体２を挿入する。この際、該ネット用の支柱１の上部支柱体３がネット４の吊り張り方向に対して、一方の端部側を垂直方向になるように挿入する（本願実施例では一方の対角線方向を垂直方向に一致させる）。Next, when the net support 1 selected as described above is erected, holes are drilled at desired intervals along the outer periphery of the outdoor space, and the lower support post of the net support 1 is formed in the hole. Insert body 2. At this time, the upper column body 3 of the net column 1 is inserted so that one end side is perpendicular to the direction in which the net 4 is suspended (in the embodiment of the present invention, one diagonal direction is perpendicular). Match the direction).

即ち、屋外空間部の外周部分が直線状に形成されている部分は、隣り合う支柱１は上部支柱体３をそれぞれ同じ方向になるように立設し、円弧状に形成されている部分は、中心点を基準とする方向にそれぞれ対角線を一致させることで、ネット４の吊り張り方向に対して対角線が垂直方向と一致することとなる。That is, the part where the outer peripheral part of the outdoor space part is formed in a straight line is such that the adjacent pillars 1 stand so that the upper pillars 3 are in the same direction, and the part formed in an arc shape is By making the diagonal lines coincide with each other in the direction with the center point as a reference, the diagonal lines coincide with the vertical direction with respect to the hanging direction of the net 4.

これにより、ネット４の受ける風方向に対して上部支柱体３は左右方向に風の影響を受け流してネット４の吊り張りを維持できるとともに、下部支柱体２の一方の角がネット４の吊り張り方向に対して垂直方向であるために、風を受ける方向に対して強度を強化することができ、安全に立設することができる。As a result, the upper support column 3 can be affected by the wind in the left-right direction with respect to the wind direction received by the net 4 to maintain the suspension of the net 4, and one corner of the lower support column 2 has the suspension of the net 4. Since the direction is perpendicular to the direction, the strength can be enhanced with respect to the direction of receiving the wind, and the apparatus can be erected safely.

このように、ネット４の吊り張りする高低及び風の影響に応じてネット用の支柱１の対角線をネット４に対して垂直方向となるように立設することで、自在に対応することができる。In this manner, the diagonal of the net support 1 can be set up vertically so as to be perpendicular to the net 4 according to the height of the net 4 and the influence of wind. .

また、上記実施例では、下部支柱体２と上部支柱体３との断面形状を同一形状に形成したが、本願発明において、ネット用の支柱１は下部支柱体２と上部支柱体３との断面形状を同一形状に形成することに限定されるものでなく、例えば、下部支柱体２の断面形状を五角形状に形成し、上部支柱体３の断面形状を三角形状に形成することで、下部支柱体２の埋設時の強度を強化するとともに、上部支柱体３の風を分散し易く構成することも可能である。Moreover, in the said Example, although the cross-sectional shape of the lower support body 2 and the upper support body 3 was formed in the same shape, in this invention, the support | pillar 1 for nets is a cross section of the lower support body 2 and the upper support body 3. The shape is not limited to the same shape. For example, the lower support column 2 is formed in a pentagonal cross section, and the upper support member 3 is formed in a triangular shape in cross section. While strengthening the strength at the time of embedding the body 2, it is possible to make it easy to disperse the wind of the upper support body 3.

また、本実施例では下部支柱体２と上部支柱体３とを一体的に形成したが、本願発明において支柱１の構成はこれに限定されるものでなく、下部支柱体２と上部支柱体３を別体に構成することで、下部支柱体２の断面形状と上部支柱体３の断面形状とを自在に設定することができ、例えば、下部支柱体２の断面形状を五角形状に形成し、上部支柱体２の断面形状を三角形状に形成することで、下部支柱体２はネット４方向に対して強度を維持することができ、上部支柱体３は風を左右方向に分散して継続性を格段に維持することができ、また、下部支柱体２の断面形状を四角形状にし、上部支柱体３の断面形状を三角形状に形成することも可能である。In the present embodiment, the lower column body 2 and the upper column body 3 are integrally formed. However, in the present invention, the configuration of the column 1 is not limited thereto, and the lower column body 2 and the upper column body 3 are not limited thereto. Is configured separately, the cross-sectional shape of the lower column body 2 and the cross-sectional shape of the upper column body 3 can be freely set, for example, the cross-sectional shape of the lower column body 2 is formed in a pentagonal shape, By forming the cross-sectional shape of the upper support body 2 in a triangular shape, the lower support body 2 can maintain the strength with respect to the net 4 direction, and the upper support body 3 distributes the wind in the left-right direction and continues. It is also possible to make the cross-sectional shape of the lower support column 2 a square shape and the cross-sectional shape of the upper support column 3 to be a triangular shape.

また、下部支柱体２の断面形状が三角形状又は多角形状に形成されているために、その各端部に沿ってプレート５を取り付けでき、下部支柱体２の埋設時の強度を格段に向上することができる。Moreover, since the cross-sectional shape of the lower column body 2 is formed in a triangular shape or a polygonal shape, the plate 5 can be attached along each end thereof, and the strength when the lower column body 2 is embedded is remarkably improved. be able to.

また、上記実施例では、下部支柱体２と上部支柱体３との断面形状を三角形状、正方形状、又は正五角形状等各辺が等辺で形成したが、本願発明において断面形状はこれに限定されるものでなく、長方形状や各角度の相違する多角形状で形成することも可能である。これにより、ネット４の吊り張り方向に対して垂直方向に一番鋭角部分を一致させる一方の角のみ鋭角に形成し、該部分による風の左右方向より分散することも可能である。Moreover, in the said Example, although cross-sectional shape of the lower support | pillar body 2 and the upper support | pillar body 3 formed each side, such as a triangle shape, square shape, or a regular pentagon shape, a cross-sectional shape is limited to this in this invention However, it may be formed in a rectangular shape or a polygonal shape having different angles. As a result, it is also possible to form only one of the corners where the most acute angle portion is perpendicular to the direction in which the net 4 is suspended, and to disperse the wind from the left and right directions of the portion.
