上記従来のフェンスにおいては、強風時にパネル体が風圧により全体的に持ち上げられたり、またパネル体が風圧により湾曲したりしてパネル体の下部が浮き上がり、パネル体の下部が支持金具から外れてしまうことがあった。また、支柱は中空部内に補強材を差し込んで補強してあるが、従来の補強材は角パイプやコ字状断面のものであったため、支持金具や他の部品を支柱にネジで取付けるために、補強材にそれらの取付ネジのための逃がし孔をいちいち加工しなければならず、その加工に大変手間がかかっていた。 As one form of a conventional fence, as shown in Patent Documents 1 and 2, a panel body assembled using an extruded shape of an aluminum alloy or the like was attached to a front surface of a support column erected at an appropriate interval from the ground with a metal fitting. There is something. As shown in FIG. 1 of Patent Document 1, the fence described in Patent Document 1 is provided with a support metal fitting (panel receiving portion 9) at the bottom of the support column and a drawing metal fitting (engaging member 6) at the upper portion of the support column. The lower part of the panel body is locked to the support bracket from above, the attracting bracket is hooked in the groove formed on the upper part of the panel body, and the screw screwed to the attracting bracket is turned to draw the panel. The body is attached to the column. In the fence described in Patent Document 2, the lower part of the panel body is locked to the support bracket (lower bracket 4) provided at the lower part of the support column, and the upper bracket 3 is attached across the upper surface of the panel body and the upper surface of the support column. The panel body is attached to the column.
In the conventional fence described above, the panel body is lifted entirely by wind pressure in strong winds, or the panel body is bent by wind pressure, the lower part of the panel body is lifted, and the lower part of the panel body is detached from the support bracket. There was a thing. In addition, the strut is reinforced by inserting a reinforcing material into the hollow part, but the conventional reinforcing material was a square pipe or a U-shaped cross section, so to attach the support bracket and other parts to the strut with screws The relief holes for the mounting screws had to be machined one by one in the reinforcing material, which was very laborious.

The support fitting 3 is fixed with a screw 24 screwed into the support column 1 from the road side by locking a rotation-preventing protrusion 23 to the support column 1. A locking groove 25 is provided on the upper surface of the support bracket 3 along the road side surface of the column 1. A groove 5 that opens downward is formed on the lower surface of the lower rail 14, and the bottom surface 5 a of the groove 5 and the wall 5 b on the site side are locked to the support fitting 3.
At the position just above the support bracket 3, a removal prevention screw 4 is provided through the support column 1 and the reinforcing material 8 from the site side, and the tip of the removal prevention screw 4 projects from the support column 1 to the road side, It is inserted into a groove 26 formed on the site side surface of the crosspiece 14. On the lower side surface of the groove 26, a ridge 6 protrudes upward, and the ridge 6 engages with the removal prevention screw 4. Further, as shown in FIGS. 1 and 2 (b), the removal prevention screw 4 is inserted through a through hole 27 formed in the connecting portion 10 of the reinforcing member 8.
The through hole 27 may be a female screw hole into which the removal prevention screw 4 is screwed, and a relief hole through which the removal prevention screw 4 is inserted may be formed in the road side and site side walls of the column 1. The support column 1 and the reinforcing member 8 are also fixed by the removal prevention screw 4.

パネル体２の支柱１への取付け方は、特許文献１記載の従来のフェンスとほぼ同様であって、まず図５（ａ）に示すように、パネル体２の下桟１４の下面の溝５を支柱１下部に取付けた支持金具３に上方より係止させ、引寄せ金具２０を上桟１３の溝２１に引っ掛け、ネジ２２を回して上桟１３を支柱１に引寄せて固定する。その後、図５（ｂ）に示すように、抜け防止ネジ４を支柱１に敷地側から挿入し、抜け防止ネジ４の先端部を下桟１４の敷地側面に形成された溝２６内に差し入れる。すると、溝２６内の突条６が抜け防止ネジ４と係合し、パネル体２の浮き上がりが規制される。 The method of attaching the panel body 2 to the column 1 is substantially the same as that of the conventional fence described in Patent Document 1. First, as shown in FIG. 5A, the groove 5 on the lower surface of the lower rail 14 of the panel body 2 is used. Is locked from above with the support fitting 3 attached to the lower part of the column 1, the attracting member 20 is hooked on the groove 21 of the upper beam 13, and the screw 22 is turned to draw the upper beam 13 to the column 1 to be fixed. Thereafter, as shown in FIG. 5B, the removal prevention screw 4 is inserted into the support column 1 from the site side, and the tip of the removal prevention screw 4 is inserted into a groove 26 formed on the side surface of the lower rail 14. . Then, the protrusion 6 in the groove | channel 26 engages with the removal prevention screw 4, and the floating of the panel body 2 is controlled.

以上に述べたように本フェンスは、支持金具３の上方に抜け防止ネジ４が支柱１から突出して設けてあり、下桟１４の溝２６内に設けた突条６が抜け防止ネジ４と係合することでパネル体２の浮き上がりを規制しているので、強風時にパネル体２が風圧で持ち上がろうとしても下桟１４が支持金具３から外れることがなく、耐風圧性能を大きく向上できる。その結果、支柱１の間隔を広げて支柱１の本数を従来の半分に減らすことが可能となった。パネル体２の支柱１への取付けは、従来のフェンスと同じように簡易に行うことができ、その後に抜け防止ネジ４を支柱１下部に敷地側からねじ込むだけでパネル体２を確実に固定でき、施工性が良い。支柱１は、パネル体２の左右方向の任意の位置に設けることができるいわゆるフリー支柱となっており、施工する現場の状況等に応じて支柱１の位置を適宜ずらすことができる。 As described above, the fence is provided with the removal prevention screw 4 protruding from the support column 1 above the support bracket 3, and the protrusion 6 provided in the groove 26 of the lower rail 14 is engaged with the removal prevention screw 4. Since the lifting of the panel body 2 is regulated by combining, the lower beam 14 does not come off from the support fitting 3 even when the panel body 2 is lifted by wind pressure in a strong wind, and the wind pressure resistance performance can be greatly improved. . As a result, it is possible to increase the interval between the columns 1 and reduce the number of columns 1 to half that of the conventional one. The panel body 2 can be attached to the column 1 as easily as a conventional fence, and the panel body 2 can be securely fixed by simply screwing the drop prevention screw 4 into the bottom of the column 1 from the site side. Good workability. The support column 1 is a so-called free support column that can be provided at an arbitrary position in the left-right direction of the panel body 2, and the position of the support column 1 can be appropriately shifted according to the situation of the construction site.

また本フェンスは、支柱１内に設ける補強材８を断面略Ｈ状としたことにより、図２（ｂ）に示すように、抜け防止ネジ４のための貫通孔２７を補強材８の繋ぎ部１０に最小限の加工で済ませられ、また図４に示すように、支持金具３を支柱１に取付けるネジ２４のための逃がし孔を省略することができる。さらに、補強材８の左右の側部９，９がコ字状断面となっているため、支柱１の側面に部品２８をネジ２９で取付ける場合でも、補強材８にそのネジ２９の逃がし孔を形成する必要がない。 Further, in this fence, the reinforcing member 8 provided in the support column 1 has a substantially H-shaped cross section, so that the through hole 27 for the removal prevention screw 4 is connected to the reinforcing member 8 as shown in FIG. As shown in FIG. 4, the relief hole for the screw 24 for attaching the support fitting 3 to the column 1 can be omitted. Further, since the left and right side portions 9, 9 of the reinforcing member 8 have a U-shaped cross section, even when the component 28 is attached to the side surface of the support column 1 with the screw 29, a relief hole for the screw 29 is provided in the reinforcing member 8. There is no need to form.

本発明は以上に述べた実施形態に限定されない。パネル体２の材質やデザインは任意であり、アルミ形材で組み立てたものに限らず、金網やパンチングパネルを用いたもの、アルミ等の鋳物で一体に形成したものであってもよい。抜け防止具４は、ネジに限らず、ピン状のものであってもよく、支柱を貫通しないもの、支柱から突出しないもの（この場合は、例えば支柱の道路側面に凹部を設けると共に、パネル体に係合部を支柱側に突出して設ける）であってもよい。また抜け防止具４は、支持具３よりも上方に設けてあればよく、必ずしも支持具３のすぐ上になくてもよい。パネル体１の係合部６は、抜け防止具４と係合してパネル体１の浮き上がりを規制できればよく、その形態は特に限定されず、例えば係合部を支柱側に突出する突起状に設けることもできる。 The present invention is not limited to the embodiments described above. The material and design of the panel body 2 are arbitrary, and are not limited to those assembled from aluminum shapes, but may be one using a wire mesh or a punching panel, or one integrally formed of a casting such as aluminum. The removal prevention tool 4 is not limited to a screw, and may be a pin-shaped one that does not penetrate the column or does not protrude from the column (in this case, for example, a recess is provided on the road side surface of the column and the panel body The engaging portion may be provided so as to protrude to the support column side). Moreover, the removal prevention tool 4 should just be provided above the support tool 3, and does not necessarily need to be just above the support tool 3. FIG. The engagement part 6 of the panel body 1 is not particularly limited as long as it can be engaged with the removal prevention tool 4 to restrict the lifting of the panel body 1, and the form thereof is not particularly limited.
