例えば、建物敷地とこの建物敷地に隣接する道路や隣地との境界に沿って設けられるフェンスとして、ユニット化されたフェンス本体の横桟部材をコンクリートブロックやコンクリート基礎に立設支持された支柱に支持することによってフェンスを容易に組み立て施工するようにしたものがある。
また、この種のフェンスとして図10および図11に示すフェンスFが提案されている(特許文献1)。
For example, as a fence provided along the boundary between a building site and the road adjacent to this building site or the adjacent site, the horizontal fence member of the unitized fence body is supported by a column supported upright on a concrete block or concrete foundation By doing this, there is one that makes it easy to assemble and install the fence.
Moreover, the fence F shown in FIG. 10 and FIG. 11 is proposed as this kind of fence (patent document 1).

すなわち、このフェンスFは、図11に示すように、引寄せ金具300の係止部311を、フェンス本体100の上胴縁110の支柱側面に設けられた溝111内に臨ませたのち、支柱200の壁面に設けられたボルト挿通孔220を介して支柱200内に臨ませた固定ボルト400を引寄せ金具300のねじ孔312にねじ込んで行き、引寄せ金具300を支柱200側に引き寄せ、図10に示すように、係止部311と、支柱200との間に、フェンス本体100に設けられた係止壁部112を挟み込んでフェンス本体100の上端部を支柱200に支持固定するようにしている。
すなわち、このフェンスFは、通常、道路等の敷地外に配置されるフェンス本体100の上端部を支柱200の敷地側に向いた面から固定ボルト400をねじ込んでフェンス本体100の上端部を支柱200に支持固定するようになっている。
したがって、敷地外から上記固定ボルト400の解締が難しく、子供等が敷地外から固定ボルト400を弛めたり、取り除いたりするいたずらを防止できる。
That is, as shown in FIG. 11, the fence F has the locking portion 311 of the drawing metal fitting 300 faced in the groove 111 provided on the side of the column of the upper trunk edge 110 of the fence body 100, and then the column The fixing bolt 400 facing the inside of the column 200 through the bolt insertion hole 220 provided on the wall surface of the 200 is screwed into the screw hole 312 of the drawing metal 300, and the drawing metal 300 is drawn to the column 200 side. As shown in FIG. 10, the upper end portion of the fence body 100 is supported and fixed to the column 200 by sandwiching the locking wall portion 112 provided on the fence body 100 between the locking portion 311 and the column 200. Yes.
In other words, the fence F is usually configured such that the upper end of the fence body 100 arranged outside the site such as a road is screwed with the fixing bolt 400 from the surface of the support 200 facing the site, and the upper end of the fence body 100 is connected to the support 200. It is designed to be fixed to support.
Therefore, it is difficult to unfasten the fixing bolt 400 from outside the site, and it is possible to prevent a child or the like from loosening or removing the fixing bolt 400 from outside the site.

特開平2010-261260号公報Japanese Unexamined Patent Publication No. 2010-261260

ところで、支柱200は、一般にアルミニウムやアルミニウム合金等の軽量金属の押出型材を加工したものが用いられている。
一方、上記フェンスFの場合、図10および図11に示すように、支柱200のフェンス本体側の壁に引寄せ金具300を上下に移動可能にする長孔210を設ける必要がある。また、フェンスは、施工現場の状況や施主の都合によって、支柱200の長さを調整しなければならならないことがある。

したがって、上記支柱200のような形状の場合、予め支柱200の下端側を長く形成し、下端側を現場の状況に応じて切断できるようにするか、いろいろな長さの支柱200を予め用意しておくようにしなければならない。
しかしながら、前者の場合、端材が多く発生するおそれがあり、後者の場合、工場で長さの異なる支柱200を多数ストックする必要があり、いずれもコストがかかるという問題が発生する。
Therefore, in the case of the shape like the support column 200, the lower end side of the support column 200 is formed long in advance and the lower end side can be cut according to the situation on the site, or the support columns 200 of various lengths are prepared in advance. You have to keep it.
However, in the former case, there is a possibility that a large amount of offcuts may be generated. In the latter case, it is necessary to stock a large number of struts 200 having different lengths at the factory, and there is a problem that both are costly.

本発明のフェンスは、以上のように、フェンス本体の上端部の支柱側壁面に設けられた金具係止部に上部固定金具のフェンス本体係止部を係止した状態で、筒状の支柱を貫通して設けられた固定ボルトを前記上部固定金具のねじ孔にねじ込んで、前記フェンス本体係止部を前記支柱側に引き寄せて前記フェンス本体係止部と、支柱外壁面との間で前記金具係止部を挟み込んで前記フェンス本体の上端部を支柱に固定するようにしたフェンスであって、前記上部固定金具は、フェンス本体係止部を有するとともに固定ボルトのねじ孔を備えた金具本体と係止爪部とを備え、前記係止爪部が前記フェンス本体係止部を前記金具係止部に係止した状態で前記支柱の上端に係止されてフェンス本体の上端を仮止め状態に支持可能に形成されているので、支柱に設ける固定ボルトのボルト挿通孔は、ボルトの径より少し大きな丸孔でよい。
したがって、フェンスの施工現場においても、電動ドリルなどの一般的な工具を用いて容易にボルト挿通孔を穿設することができる。すなわち、施工現場で長尺の型材を必要な支柱の長さに切断し、上記のようにしてボルト挿通孔を穿設して支柱とすることができるので、端材の発生を少なくすることができるとともに、いろいろな長さの支柱をストックしておく必要がなく、コストダウンをはかることができる。しかも,敷地外から上記固定ボルトの解締が難しく、子供等が敷地外から固定ボルトを弛めたり、取り除いたりするいたずらを防止できる。
As described above, the fence according to the present invention is configured so that the cylindrical column is attached in a state where the fence body locking portion of the upper fixing bracket is locked to the bracket locking portion provided on the column side wall surface of the upper end portion of the fence body. A fixing bolt provided through is screwed into a screw hole of the upper fixing bracket, and the fence main body locking portion is pulled toward the support column side, and the metal fitting is provided between the fence main body locking portion and the outer wall surface of the support column. A fence in which an upper end portion of the fence body is fixed to a support by sandwiching an engaging portion, wherein the upper fixing metal fitting has a fence main body engaging portion and is provided with a fixing bolt screw hole and A locking claw portion, and the locking claw portion is locked to the upper end of the column in a state where the fence main body locking portion is locked to the metal fitting locking portion, and the upper end of the fence main body is temporarily fixed. Because it is formed to be supportable Bolt insertion hole of the fixing bolt provided on the strut can be a little larger round hole than the diameter of the bolt.
Therefore, the bolt insertion hole can be easily drilled using a general tool such as an electric drill even at a fence construction site. In other words, it is possible to cut the long mold material to the length of the required struts at the construction site and drill the bolt insertion holes as described above to make the struts, thereby reducing the generation of end materials. In addition, it is not necessary to stock struts of various lengths, and costs can be reduced. In addition, it is difficult to unfasten the fixing bolt from outside the site, and children and the like can be prevented from tampering with loosening or removing the fixing bolt from outside the site.

さらに、フェンス本体を、上端部の支柱側壁面に、上下から張り出す上下一対の金具係止部と金具本体が遊嵌される凹溝を有する支柱側に開口する凹溝を備える構成とすれば、金具本体が凹溝内をスムーズにスライドする。
したがって、金具本体を凹溝内に遊嵌状態にセットし、係止爪部を支柱の上端に係止させた状態でフェンス本体を水平方向にずらせて固定ボルトのボルト挿通孔とねじ孔の位置合わせを容易に行うことができる。
Furthermore, if the fence body is configured to include a pair of upper and lower metal fitting locking portions protruding from above and below on the column side wall surface of the upper end portion and a concave groove that opens to the column side having a concave groove in which the metal fitting body is loosely fitted. The bracket body slides smoothly in the groove.
Therefore, the bracket body is set in a loose fit in the groove, and the fence body is shifted horizontally with the locking claw locked to the upper end of the column, and the bolt insertion hole and screw hole position of the fixing bolt Matching can be performed easily.

また、上部固定金具の係止爪部を、金具本体から支柱側に張り出すように設けられた略逆L字形をしている構成とすれば、逆L字の縦辺部分が支柱の内部に臨み、安定した係止状態になる。すなわち、固定ボルトを金具本体のねじ孔に締め込まない状態でも安定した仮止め状態とすることができるので、安全に施工することができる。   Further, if the latching claw portion of the upper fixing bracket has a substantially inverted L shape provided so as to protrude from the bracket body to the column side, the vertical side portion of the inverted L shape is placed inside the column. It will be in a stable locked state. That is, even if the fixing bolt is not tightened into the screw hole of the metal fitting body, a stable temporary fixing state can be obtained, so that the construction can be performed safely.

一方、支柱の上部端面に受けられ上部開口を塞ぐキャップ本体と、前記上部開口から支柱内に嵌入される支柱嵌入部を有し、この支柱嵌入部が、金具本体のねじ孔にねじ込まれる固定ボルトが挿通されてキャップ本体を上部端面に受けられた状態に保持するボルト挿通孔を備えている支柱キャップによって支柱の上端を塞ぐ構成とすれば、支柱の上端側からの支柱内へのゴミや雨水の入り込みを防止できるとともに、固定ボルトがしっかりとねじ孔にねじ込まれていると支柱キャップが支柱からはずれない。すなわち、支柱キャップ専用の固定ねじを取り付ける作業が不要となり、作業性に優れている。   On the other hand, it has a cap body that is received by the upper end face of the column and closes the upper opening, and a column insertion portion that is inserted into the column from the upper opening, and this column insertion portion is screwed into the screw hole of the metal fitting body If the upper end of the column is closed by a column cap that has a bolt insertion hole that holds the cap body in a state where the cap body is received by the upper end surface, dust and rainwater entering the column from the upper end side of the column Can be prevented, and if the fixing bolt is firmly screwed into the screw hole, the support cap will not come off the support. That is, the work of attaching a fixing screw for the column cap is unnecessary, and the workability is excellent.

さらに、上部固定金具の金具本体が、支柱側の面にねじ孔の支柱側端から徐々に拡径するように設けられたボルト誘導部を備えている構成とすれば、固定ボルトをねじ孔にねじ込む際に、ボルト誘導部のテーパ面に固定ボルトの先端があたり、固定ボルトがスムーズにねじ孔に誘導される。
したがって、固定ボルトの締め込み作業が容易になる。
Furthermore, if the bracket body of the upper fixing bracket is configured to have a bolt guiding portion provided on the column side surface so as to gradually increase the diameter from the column end of the screw hole, the fixing bolt is formed into the screw hole. When screwing in, the tip of the fixing bolt hits the tapered surface of the bolt guiding portion, and the fixing bolt is smoothly guided into the screw hole.
Therefore, the fixing bolt can be easily tightened.

以下に、このフェンス1の施工方法の1例を工程順に説明する。
(1)長尺の押出型材を規格化された長さあるいは施工現場の状況に応じた長さに切断し、支柱3の上端側にボルト挿通孔32を穿設する。
なお、押出型材の切断およびボルト挿通孔32の穿設は、工場でもよいし、施工現場で行ってもよい。
(2)図1、図3および図6に示すように、受け金具31をボルト挿通孔32が穿設された壁面の一方に取り付けるとともに、支柱3の下端側をベース8に埋め込み、受け金具31が敷地外を臨むように支柱3をベース8に立設状態とする。
なお、受け金具31の取り付けは、支柱3をベース8に埋め込む前でも後でも構わない。
(3)図6に示すように、上胴縁21の第1凹溝部21aの凹溝21d内に金具本体61を遊嵌状態にはめ込むとともに、係止爪部62を金具係止部21bと金具係止部21cの隙間を介して第1凹溝部21a外に突出するようにセットする。

なお、この状態で、第1嵌入部52のボルト挿通孔52aと、支柱3のボルト挿通孔32が一直線上に並んだ状態となる。
(6)上記(5)の状態を保持しながら、図9に示すように、固定ボルト63をフェンス本体2とは逆側の支柱3の壁に設けられたボルト挿通孔32から、ボルト挿通孔52a、他方のボルト挿通孔の順に通し、図4に示すように、固定ボルト63が支柱3を貫通した状態とするとともに、固定ボルト63の先端を金具本体61のねじ孔61aにねじ込み、金具本体61を支柱3側に引き寄せて、上下の金具係止部21b,21cを金具本体61と、支柱3の外壁面とで挟み込込ませることによってフェンス本体2の上端部を支柱3の上端部に固定する。
すなわち、この状態で、支柱キャップ5が固定ボルト63によって上方へ抜け無いように固定される。
また、第1嵌入部52のボルト挿通孔52aの軸方向両側の壁面が、支柱3のボルト挿通孔32が設けられた対面する内壁面に圧接状態となっているので、固定ボルト63の頭部から支柱3の壁面にかかる力が第1嵌入部52によって受けられている。
Below, an example of the construction method of this fence 1 is demonstrated in order of a process.
(1) A long extruded mold material is cut into a standardized length or a length according to the situation at the construction site, and a bolt insertion hole 32 is formed in the upper end side of the support column 3.
Note that the cutting of the extrusion mold material and the drilling of the bolt insertion hole 32 may be performed at a factory or at a construction site.
(2) As shown in FIGS. 1, 3, and 6, the receiving bracket 31 is attached to one of the wall surfaces provided with the bolt insertion holes 32, and the lower end side of the support column 3 is embedded in the base 8, The support column 3 is set up on the base 8 so as to face the outside of the site.
Note that the mounting of the receiving bracket 31 may be performed before or after the support column 3 is embedded in the base 8.
(3) As shown in FIG. 6, the metal fitting body 61 is fitted in the loose groove 21 d of the first concave groove portion 21 a of the upper trunk edge 21, and the locking claw 62 is connected to the metal locking portion 21 b and the metal fitting. It sets so that it may protrude outside the 1st ditch | groove part 21a through the clearance gap between the latching | locking parts 21c.
(4) As shown in FIG. 7, the receiving portion 31 a of the receiving fitting 31 engages with the receiving fitting fitting groove 22 b of the lower trunk edge 22, and the locking claw 62 b is inserted into the supporting post 3 from the upper end opening of the supporting post 3. Insert the fence body 2 into a temporarily fixed state.
(5) As shown in FIG. 8, the column cap 5 is supported with the fence body 2 supported by a hand or the like so that the outer wall surfaces of the metal fitting locking portions 21 b and 21 c of the fence body 2 are in close contact with the outer wall surface of the column 3. As shown in FIG. 9, the first insertion portion 52 and the second insertion portion 53 are completely inserted into the support column 3 and set so that the lower surface of the cap body 51 is in close contact with the upper end of the support column 3.
In this state, the bolt insertion hole 52a of the first insertion portion 52 and the bolt insertion hole 32 of the support column 3 are aligned in a straight line.
(6) While maintaining the state of (5) above, as shown in FIG. 9, the fixing bolt 63 is inserted into the bolt insertion hole 32 from the bolt insertion hole 32 provided on the wall of the column 3 opposite to the fence body 2. 52a and the other bolt insertion hole are passed through in this order, and as shown in FIG. 4, the fixing bolt 63 passes through the column 3, and the tip of the fixing bolt 63 is screwed into the screw hole 61a of the metal fitting body 61. The upper end of the fence body 2 is moved to the upper end of the column 3 by pulling 61 toward the column 3 and sandwiching the upper and lower bracket locking portions 21b and 21c between the bracket main body 61 and the outer wall surface of the column 3. Fix it.
That is, in this state, the support cap 5 is fixed by the fixing bolt 63 so as not to be pulled upward.
Further, the wall surfaces on both axial sides of the bolt insertion hole 52a of the first insertion portion 52 are in pressure contact with the facing inner wall surface provided with the bolt insertion hole 32 of the support column 3, so that the head of the fixing bolt 63 The force applied to the wall surface of the column 3 is received by the first insertion portion 52.

このフェンス1は、上記のように、支柱3の敷地側壁面から固定ボルト63を、フェンス本体2の上部固定金具6の金具本体61のねじ孔61aにねじ込んでフェンス本体2の上端部を支柱3に支持固定するようにしたので、敷地外側から固定ボルト63を解締しにくい。   In this fence 1, as described above, the fixing bolt 63 is screwed into the screw hole 61 a of the metal fitting body 61 of the upper fixing fitting 6 of the fence body 2 from the site side wall surface of the pillar 3, and the upper end portion of the fence body 2 is attached to the pillar 3. It is difficult to unfasten the fixing bolt 63 from the outside of the site.

また、ボルト挿通孔32は、固定ボルト63のねじ部63bが挿通される丸孔でよい。
したがって、フェンス1の施工現場においても、電動ドリルなどの一般的な工具を用いて容易にボルト挿通孔32を穿設することができる。すなわち、施工現場で長尺の型材を必要な支柱の長さに切断し、上記のようにしてボルト挿通孔を穿設して支柱3とすることができるので、端材の発生を少なくすることができるとともに、いろいろな長さの支柱サをストックしておく必要がなく、コストダウンをはかることができる。
Further, the bolt insertion hole 32 may be a round hole through which the threaded portion 63b of the fixing bolt 63 is inserted.
Accordingly, the bolt insertion hole 32 can be easily drilled using a general tool such as an electric drill even at the construction site of the fence 1. That is, it is possible to cut a long mold material to a necessary length of a support column at a construction site and to make a bolt insertion hole as described above to form the support column 3, thereby reducing the generation of end materials. It is possible to reduce costs by eliminating the need to stock struts of various lengths.

さらに、上部固定金具6の金具本体61が第1凹溝部21aの凹溝21dに遊嵌状態にはまり込むので、仮止め状態においても金具本体61を凹溝21dに沿ってスライドさせて、ねじ孔61aと支柱3のボルト挿通孔32の位置合わせを容易に行うことができる。   Furthermore, since the metal fitting body 61 of the upper fixing metal fitting 6 fits into the loose groove 21d of the first concave groove portion 21a in a loosely fitting state, the metal fitting body 61 is slid along the concave groove 21d even in the temporarily fixed state, and screw holes 61a and the bolt insertion hole 32 of the support | pillar 3 can be aligned easily.

また、上部固定金具6の係止爪部62が略逆L字形をしているので、係止爪62bが支柱の内部に臨み、安定した係止状態になる。すなわち、固定ボルト63を金具本体61のねじ孔61aにねじ込んでいない安定した仮止め状態とすることができる。したがって、固定ボルト63のねじ込み作業を安全かつ容易に行える。   Moreover, since the latching claw part 62 of the upper fixing bracket 6 has a substantially inverted L shape, the latching claw 62b faces the inside of the support column and is in a stable latched state. In other words, the fixing bolt 63 can be in a stable temporarily fixed state in which the fixing bolt 63 is not screwed into the screw hole 61 a of the metal fitting body 61. Therefore, the fixing bolt 63 can be screwed in safely and easily.

また、フェンス本体2の固定ボルト63が、支柱キャップ5の第1嵌入部52に設けられたねじ挿通孔52aにも挿通された状態で上部固定金具6の金具本体のねじ孔61aにねじ込まれるので、支柱キャップ5が、固定ボルト63によって抜け止め状態になる。
したがって、支柱キャップ5専用の固定ボルトが必要が無く、部品点数を少なくすることができるとともに、作業も簡略化できる。
In addition, the fixing bolt 63 of the fence body 2 is screwed into the screw hole 61a of the metal fitting body of the upper fixing metal fitting 6 while being inserted into the screw insertion hole 52a provided in the first insertion portion 52 of the support cap 5. The support cap 5 is prevented from being detached by the fixing bolt 63.
Therefore, there is no need for a fixing bolt dedicated to the column cap 5, the number of parts can be reduced, and the work can be simplified.

また、第1嵌入部52のボルト挿通孔52aの軸方向両側の壁面が、支柱3のボルト挿通孔32が設けられた対面する内壁面に圧接状態となり、固定ボルト63の頭部から支柱3の壁面にかかる力が第1嵌入部52によって受けられるので、固定ボルト63の過締め込みによって支柱3の壁面が変形するを防止することができる。   Further, the wall surfaces on both sides in the axial direction of the bolt insertion holes 52a of the first insertion portion 52 are brought into pressure contact with the facing inner wall surfaces provided with the bolt insertion holes 32 of the support columns 3, and the heads of the support bolts 3 Since the force applied to the wall surface is received by the first insertion portion 52, it is possible to prevent the wall surface of the support column 3 from being deformed by overtightening the fixing bolt 63.

さらに、上部固定金具6の金具本体61が、支柱3側の面にねじ孔61aの支柱側端から徐々に拡径するように設けられたボルト誘導部61bを備えているので、固定ボルト63をねじ孔61aにねじ込む際に、ボルト誘導部61bのテーパ面にねじ部63b先端があたり、ねじ部63bがスムーズにねじ孔61aに誘導される。
したがって、固定ボルト63のねじ込み作業が容易になる。
Furthermore, since the metal fitting body 61 of the upper fixing metal fitting 6 is provided with a bolt guiding portion 61b provided on the surface on the support column 3 side so as to gradually increase in diameter from the end of the screw hole 61a. When screwing into the screw hole 61a, the tip of the screw part 63b hits the tapered surface of the bolt guiding part 61b, and the screw part 63b is smoothly guided to the screw hole 61a.
Therefore, the screwing operation of the fixing bolt 63 is facilitated.

なお、図4、図8において、27は第1凹溝部21aの支柱3に当接する部分以外で凹溝21dを覆い隠す長尺の蓋部材である。   4 and 8, reference numeral 27 denotes a long lid member that covers the groove 21 d except for the portion of the first groove 21 a that abuts on the column 3.
