Description

本発明は柵および柵用パネル、特に、パイプ製の柵および柵用パネルに関する。 The present invention relates to a fence and a fence panel, and more particularly to a pipe fence and a fence panel.

従来、車道と歩道との分離する柵（パイプフェンス）、道路の中央分離帯等に設置される柵（ガードフェンス）、公園などの境界柵や案内柵等は、上下に配置される一対の胴縁と、両端がそれぞれ前記胴縁に溶接される縦格子とから構成されていた。ところが、かかる溶接による接続では、柵を傾斜地に設置する際、傾斜の程度に応じて、それぞれの角度になるよう胴縁に縦格子を斜めに溶接する必要が生じ、製造管理および在庫管理が煩雑になるという問題があった。
このため、溶接に替えて、機械的に胴縁に縦格子を連結し、設置現場において両者の傾斜角度を調整自在にする技術が開示されている（例えば、特許文献１参照）。 Conventionally, a fence (pipe fence) that separates the roadway from the sidewalk, a fence (guard fence) that is installed in the median strip of the road, a boundary fence such as a park, a guide fence, etc., are a pair of trunks that are arranged vertically The frame was composed of an edge and a vertical grid welded to the body edge at both ends. However, in such a connection by welding, when installing the fence on an inclined ground, it is necessary to weld a vertical lattice diagonally to the trunk edge so as to be at each angle according to the degree of inclination, and manufacturing management and inventory management are complicated. There was a problem of becoming.
For this reason, instead of welding, a technique is disclosed in which a vertical lattice is mechanically coupled to the body edge so that the inclination angle of both can be adjusted at the installation site (see, for example, Patent Document 1).

特開２００４−３６０３７２（第３−４頁、図５）JP-A-2004-360372 (page 3-4, FIG. 5)

しかしながら、特許文献１に開示された技術には以下の問題があった。すなわち、該技術は、縦格子の両端部に角パイプが溶接または両端部が角パイプ状に絞り加工され、該角パイプ部に貫通孔が形成されている。また、胴縁には角パイプが挿入可能な角穴が形成されている。そして、縦格子の角パイプ部が胴縁の角穴に挿入された状態で、胴縁内に係止棒を挿入し、該係止棒を前記貫通孔に挿通させることによって、縦格子と胴縁との連結するものである。
（あ）このため、角パイプの溶接または角パイプ状の絞り加工が高価であるため、コスト競争力が劣るという問題があった。
（い）また、長尺の係止棒が撓む（弾性変形する）ため、係止棒を前記貫通孔に挿通させる作業が困難であって、作業性が悪いという問題があった。
（う）さらに、前記作業性を改善するため、貫通孔を大きくすると、組立後のガタ（遊び）が大きくなるという問題があった。 However, the technique disclosed in Patent Document 1 has the following problems. That is, in this technique, square pipes are welded to both ends of the vertical lattice, or both ends are drawn into a square pipe shape, and through holes are formed in the square pipe portions. In addition, a square hole into which the square pipe can be inserted is formed on the trunk edge. Then, with the square pipe portion of the vertical grid inserted into the square hole of the trunk edge, a locking rod is inserted into the trunk edge, and the locking bar is inserted through the through hole, thereby allowing the vertical grid and the trunk to be inserted. It connects with the edge.
(A) For this reason, there is a problem that cost competitiveness is inferior because square pipe welding or square pipe-shaped drawing is expensive.
(Ii) Further, since the long locking rod bends (elastically deforms), it is difficult to insert the locking rod into the through hole, and there is a problem that workability is poor.
(Iii) Further, when the through hole is enlarged in order to improve the workability, there is a problem that play (play) after assembly becomes large.

本発明は、このような問題を解決するためになされたものであり、簡素な構成によって製造コストを抑えると共に、設置現場における施工を容易にし、さらに、組立後のガタを最少にする柵および柵用パネルを提供することを目的とする。 The present invention has been made in order to solve such problems.

The convex part of the material is locked.
(3) Further, the vertical lattice has a circular outer shape,

The convex portion of the support member is locked to the concave portion or the through hole of the vertical lattice that is inserted into the groove portion of the support member through the insertion hole.

本発明に係る柵は以上の構成であるから、以下の効果を奏する。
（ｉ）本発明に係る柵は、胴縁に縦格子が挿入自在な挿入孔が形成され、縦格子の両端部に凹部または貫通孔が形成され、支持材が溝形状で、その側壁に凸部が形成されているから、挿入孔を通過して支持材の溝部に挿入した縦格子は、その凹部または貫通孔に支持材の凸部が係止しているため、胴縁から抜け出すことがない。また、かかる係止状態の縦格子は支持材（胴縁に同じ）の長手方向に対して傾動するから、縦格子を傾斜させて設置することができる。また、構成が簡素であるから製造コストを安価に抑えることができ、また、設置現場における施工が容易である。さらに、常に前記係止をしているから、組立後のガタを最少にすることができる。 Since the fence which concerns on this invention is the above structure, there exist the following effects.
(I) The fence according to the present invention is formed with insertion holes through which the vertical lattice can be freely inserted in the trunk edge, concave portions or through-holes are formed at both ends of the vertical lattice, the support material has a groove shape, and protrudes on the side wall. The vertical lattice that has been inserted into the groove portion of the support material through the insertion hole can be pulled out from the trunk edge because the convex portion of the support material is locked in the concave portion or the through hole. Absent. In addition, since the vertical lattice in the locked state is tilted with respect to the longitudinal direction of the support member (same as the trunk edge), the vertical lattice can be installed in an inclined state. In addition, since the configuration is simple, the manufacturing cost can be kept low, and the construction at the installation site is easy. Furthermore, since the locking is always performed, the backlash after assembly can be minimized.

（ｉｉ）また、支持材を動かないようにして縦格子を挿入後傾けることにより、凹部または貫通孔に凸部を係止させたものであるから、組み立てが容易であると共に、一旦係止した後は、縦格子が支持材から抜け出すことがない（縦格子の軸方向に、相当大きな力を掛けても、前記係止が外れることがない）ため、柵の信頼性の向上や保全性の向上が図られる。
（ｉｉｉ）また、縦格子の外形が円形であって、縦格子を回転することによって、凹部または貫通孔に凸部を係止させたものであるから、かかる係止作業が容易である（比較的小さな力で係止する）と共に、一旦係止した後は、縦格子が支持材から抜け出すことがない（縦格子の軸方向に、相当大きな力を掛けても、前記係止が外れることがない）ため、柵の信頼性の向上や保全性の向上が図られる。 (Ii) In addition, since the convex portion is locked to the concave portion or the through hole by tilting after inserting the vertical lattice so as not to move the support material, the assembly is easy and it is temporarily locked. After that, the vertical grid will not come out of the support material (the locking will not be released even if a considerable force is applied in the axial direction of the vertical grid), improving the reliability and maintenance of the fence. Improvement is achieved.
(Iii) Since the vertical lattice has a circular outer shape, and the convex portion is locked to the concave portion or the through hole by rotating the vertical lattice, the locking operation is easy (comparison) Once locked, the vertical grid will not come out of the support (even if a considerable force is applied in the axial direction of the vertical grid, the lock may be released). Therefore, it is possible to improve the reliability and maintainability of the fence.

（ｉｖ）また、支持材の側端縁と隅部との合計４箇所が胴縁の内面に当接しているから、支持材が胴縁に拘束され両者の間にガタがない。
（ｖ）また、支持材がばね鋼板によって形成されるから、前記係止作業が容易になると共に、一旦係止した後は、確実に弾性復元（スプリングバック）して前記係止を長期間にわたって継続するため、柵の信頼性の向上や保全性の向上が図られる。 (Iv) In addition, since a total of four locations of the side edges and corners of the support material are in contact with the inner surface of the body edge, the support material is restrained by the body edge and there is no backlash between the two.
(V) Further, since the support material is formed of a spring steel plate, the locking operation is facilitated, and once locked, it is elastically restored (spring back) for a long period of time. In order to continue, the reliability and maintenance of the fence will be improved.

（ｖｉ）さらに、本発明に係る柵用パネルは以上の構成であるから、部材構成が簡素であって、施工が容易である。特に、挿入孔を丸孔にすれば、加工が迅速かつ安価になる。また、凹部が狭搾部に挟まれたまま縦格子が傾動するため、設置場所の傾斜に応じた角度に縦格子を倒すことができると共に、組立後のガタが最少に抑えられる。 (Vi) Furthermore, since the fence panel according to the present invention has the above-described configuration, the member configuration is simple and the construction is easy. In particular, if the insertion hole is a round hole, the processing is quick and inexpensive. In addition, since the vertical lattice tilts while the recess is sandwiched between the narrowed portions, the vertical lattice can be tilted at an angle corresponding to the inclination of the installation place, and the assembled play is minimized.

(overall structure)
FIG. 1 is a front view showing a fence according to Embodiment 1 of the present invention. In FIG. 1, a fence 1 is inserted into a pair of trunk edges 10 a, 10 b, vertical lattices 30 a, 30 b,. Of supporting members 20a, 20b (shown by broken lines) holding one end of 30a, 30b, 30c,..., And vertical lattices 30a, 30b, 30c,. Support members 20c and 20d (shown by broken lines) that hold the other end, and support columns 3a and 3b erected on the ground 2 are provided.

なお、胴縁１０ａ、１０ｂについて、支持材２０ａ、２０ｂ、２０ｃ、２０ｄについて、および縦格子３０ａ、３０ｂ、３０ｃ・・・・について、それぞれに共通する内容を説明する際は、添え字「ａ、ｂ・・・・」を省略して、それぞれ「胴縁１０」、「支持材２０」および「縦格子３０」と称する。また、以下の各部材を説明する図は、全体構成を説明する図１に組み立てられた状態を基準にして、正面図、側面図および平面図を規定する。 For the trunk edges 10a, 10b, the support members 20a, 20b, 20c, 20d, and the vertical lattices 30a, 30b, 30c,. ... are omitted and referred to as “body edge 10”, “support material 20”, and “vertical lattice 30”, respectively. Further, the drawings for explaining the following members define a front view, a side view, and a plan view on the basis of the state assembled in FIG.

柵１は「梯子」状であって、胴縁１０の両端が地面２に立設された一対の柱３ａ、３ｂにそれぞれ取り付けられている。なお、図１において、縦格子３０は胴縁１０の軸方向にに対して直角に連結されているが、傾斜して連結することができるものである（すなわち、平行四辺形状になる。図示しない）また、胴縁１０の一対の柱３ａ、３ｂへの取り付け要領は限定するものではない。なお、柱３ａ、３ｂのそれぞれに共通する内容を説明する際は、添え字「ａ、ｂ」を省略して、それぞれ「柱３」と称する場合がある。また、地面２とは、文字通りの陸上の地面に限定するものではなく、海底や河床、あるいは道路、建建築物ないし機械等の構造物を含むものを指している。 The fence 1 has a “ladder” shape, and both ends of the trunk edge 10 are respectively attached to a pair of pillars 3 a and 3 b erected on the ground 2. In FIG. 1, the vertical lattice 30 is connected at right angles to the axial direction of the trunk edge 10, but can be connected with an inclination (that is, has a parallelogram shape, not shown). In addition, the attachment procedure of the trunk edge 10 to the pair of pillars 3a and 3b is not limited. In addition, when explaining the content common to each of the pillars 3 a and 3 b, the subscript “a, b” may be omitted and each may be referred to as “pillar 3”. Moreover, the ground 2 is not limited to the literal land surface, but includes the seabed, riverbed, roads, buildings, or structures such as machines.

（胴縁）
図２は本発明の実施形態１に係る柵における胴縁を示す、（ａ）は平面図、（ｂ）は正面図、（ｃ）は側面図、（ｄ）は一部断面にして模式的に示す斜視図である。図２において、胴縁１０は丸鋼管（断面円形）であって、上面（図２の（ｃ）において１２時の位置）に、縦格子３０が挿入自在（正確には、縦格子３０の凸部３９が通過自在、これについては別途詳細に説明する）な挿入孔１１が複数形成されている。
なお、挿入孔１１は縦格子３０（正確には、縦格子３０の凸部３９）が通過自在な形状である限り円形に限定するものではなく、楕円であっても、矩形（縦格子３０が角鋼管等の断面矩形状の場合）であってもよい。また、柵１が傾斜地に設置される場合には、挿入孔１１を軸方向に長い長孔や、丸孔であっても縦格子３０の外径よりも大きな孔（いわゆるバカ孔）にしておけば、縦格子３０を胴縁１０の軸方向に対して容易に傾斜させることができる。 (Trunk edge)
2A and 2B show trunk edges of the fence according to Embodiment 1 of the present invention, FIG. 2A is a plan view, FIG. 2B is a front view, FIG. 2C is a side view, and FIG. It is a perspective view shown in FIG. In FIG. 2, the trunk edge 10 is a round steel pipe (circular cross section), and a vertical lattice 30 can be inserted on the upper surface (position at 12 o'clock in FIG. 2C) (exactly, the convexity of the vertical lattice 30 is A plurality of insertion holes 11 are formed, through which the portion 39 can pass, which will be described in detail separately.
The insertion hole 11 is not limited to a circle as long as the vertical lattice 30 (exactly, the convex portion 39 of the vertical lattice 30) can pass therethrough. (In the case of a rectangular section such as a square steel pipe). Further, when the fence 1 is installed on an inclined ground, the insertion hole 11 may be a long hole that is long in the axial direction or a hole that is larger than the outer diameter of the vertical lattice 30 (so-called fool hole). For example, the vertical lattice 30 can be easily inclined with respect to the axial direction of the trunk edge 10.

また、両端部の側面（図２の（ｃ）において３時の位置および９時の位置）には通し孔１２が形成されている。そして、柱３ａ、３ｂには柵１を取り付けるための取り付け用金具（図示しない）が設置され、取り付け用金具には取り付け用孔が形成されているから、該取り付け用孔と通し孔１２とを同時に貫通する通しボルト（図示しない）によって、柱３ａ、３ｂに柵１（胴縁１０に同じ）を取り付けることが可能になる。
また、通し孔１２は胴縁１０の軸方向に長い長孔になっているから、柱３ａと柱３ｂとの施工がバラついても（間隔や平行度がズレても）、取り付けが容易になっている。 Further, through holes 12 are formed on the side surfaces of the both end portions (the 3 o'clock position and the 9 o'clock position in FIG. 2C). Since the mounting brackets (not shown) for mounting the fence 1 are installed on the pillars 3a and 3b, and mounting holes are formed in the mounting brackets, the mounting holes and the through holes 12 are connected to each other. Through the through bolts (not shown) penetrating at the same time, the fence 1 (same as the trunk edge 10) can be attached to the columns 3a and 3b.
Further, since the through-hole 12 is a long hole that is long in the axial direction of the trunk edge 10, even if the construction of the pillar 3a and the pillar 3b varies (even if the interval or parallelism is shifted), the attachment becomes easy. ing.

（縦格子）
図３は本発明の実施形態１に係る柵における縦格子を示す、（ａ）平面図、（ｂ）は一部破断した正面図、（ｃ）は側面図、（ｄ）は一部断面にして模式的に示す斜視図である。
図３において、縦格子３０は丸鋼管（断面円形）であって、両端面から所定の距離に貫通孔３１が形成されている。 (Vertical grid)

In FIG. 3, a vertical lattice 30 is a round steel pipe (circular cross section), and a through hole 31 is formed at a predetermined distance from both end faces.

なお、貫通孔３１は後記する支持材２０の凸部２１（これについては、別途詳細に説明する）が係止自在な限り、その形状は図示するものに限定するものではなく、所定深さの凹部であってもよい。さらに、貫通孔３１（または凹部）の形成要領も限定するものではなく、機械加工（たとえば、ドリル切削）または塑性加工（たとえば、パンチ打ち抜き）の何れであってもよい。
なお、縦格子３０の先端面３８と側面３６との角部３７に面取り部を形成してもよい。このとき、縦格子３０を胴縁１０の挿入孔１１や支持材２０の懐内に挿入することが容易になる。 Note that the shape of the through hole 31 is not limited to that shown in the drawing as long as a convex portion 21 (which will be described in detail later) of the support member 20 to be described later can be locked. It may be a recess. Furthermore, the formation procedure of the through-hole 31 (or the recess) is not limited, and any of machining (for example, drill cutting) or plastic processing (for example, punching) may be used.
A chamfered portion may be formed at a corner portion 37 between the front end surface 38 and the side surface 36 of the vertical lattice 30. At this time, it becomes easy to insert the vertical lattice 30 into the insertion hole 11 of the trunk edge 10 or the pocket of the support member 20.

（支持材）
図４は本発明の実施形態１に係る柵における支持材を示す、（ａ）は平面図、（ｂ）は正面図、（ｃ）は凸部を示す側面視の断面図、（ｄ）は凸部を示す平面視の断面図、（ｅ）は凸部を模式的に示す斜視図である。図４において、支持材２０は、ばね鋼の薄板（たとえば、厚さ０．６〜１．５ｍｍ）を曲げ加工したものであって、底面部２８と一対の側面部２６からなる正面視においてコ字状の溝形を呈している。そして、側面部２６には、長手方向で内側に向かって突出した複数の凸部２１が形成されている。凸部２１はエンボス加工によって形成されたものであって、先端範囲は略球面の一部であって、裾野範囲は側面部２６に滑らかに連なっている。なお、以下の説明において、底面部２８と一対の側面部２６に囲まれた範囲であって、概ね凸部２１より底面部２８に近い範囲を「懐部２９」と称す。 (Support material)
FIG. 4: shows the support material in the fence which concerns on Embodiment 1 of this invention, (a) is a top view, (b) is a front view, (c) is sectional drawing of the side view which shows a convex part, (d) is Sectional drawing of the planar view which shows a convex part, (e) is a perspective view which shows a convex part typically. In FIG. 4, the support member 20 is formed by bending a spring steel thin plate (for example, a thickness of 0.6 to 1.5 mm). It is shaped like a groove. A plurality of convex portions 21 projecting inward in the longitudinal direction are formed on the side surface portion 26. The convex portion 21 is formed by embossing, and the tip end range is a part of a substantially spherical surface, and the skirt range is smoothly connected to the side surface portion 26. In the following description, a range surrounded by the bottom surface portion 28 and the pair of side surface portions 26 and generally closer to the bottom surface portion 28 than the convex portion 21 is referred to as a “head portion 29”.

なお、支持材２０は無負荷状態で、一対の側面部２６が互いに平行であるものに限定するものではなく、後記するように、支持材２０を弾性変形させて胴縁１０内に挿入自在であって、凸部２１が縦格子３０の貫通孔３１に係止する限り、一対の側面部２６の側縁２５同士の間隔が、側面部２６と底面部２８との境界に相当する隅部２７同士の間隔よりも、大きくてもよい。反対に、支持材２０の懐部２９に縦格子３０が挿入自在である限り、一対の側面部２６の側縁２５同士の間隔が、側面部２６と底面部２８との境界に相当する隅部２７同士の間隔よりも、小さくてもよい。 The support member 20 is not limited to the unloaded state and the pair of side surface portions 26 are parallel to each other. As described later, the support member 20 can be inserted into the trunk edge 10 by being elastically deformed. And as long as the convex part 21 latches in the through-hole 31 of the vertical lattice 30, the space | interval of the side edges 25 of a pair of side part 26 is the corner part 27 corresponded to the boundary of the side part 26 and the bottom face part 28. It may be larger than the interval between them. On the contrary, as long as the vertical lattice 30 can be inserted into the pocket 29 of the support member 20, the distance between the side edges 25 of the pair of side surfaces 26 corresponds to the boundary between the side surface 26 and the bottom surface 28. It may be smaller than the interval between 27.

また、隅部２７は所定の曲率半径を具備するものである。
さらに、底面部２８は平面であるものを示しているが本発明はこれに限定するものではなく、断面円弧状であってもよい。同様に、側面部２６は平面に限定するものではなく、後記する組立作業を可能にする限り、断面円弧状であったりしてもよい。
なお、図１において、一方の胴縁１０に２本の支持材２０が配置されているが、胴縁１０と略同じ長さの一本物であってもよい。 The corner 27 has a predetermined radius of curvature.
Furthermore, although the bottom surface portion 28 is a flat surface, the present invention is not limited to this, and the cross-sectional arc shape may be used. Similarly, the side surface portion 26 is not limited to a flat surface, and may be arcuate in cross section as long as assembly work described later is possible.
In FIG. 1, two support members 20 are disposed on one trunk edge 10, but a single object having substantially the same length as the trunk edge 10 may be used.

（柵の組立−１）
図５および図６は本発明の実施形態１に係る柵の組立要領を工程を追って説明する、図５は正面図、図６は平面視の部分断面図であって、図５の（ａ）が図６の（ａ）に、図５の（ｂ）および（ｃ）が図６の（ｃ）にそれぞれ対応し、図６の（ｂ）は図５の（ａ）から（ｂ）に移行する途中を示している。なお、上側の胴縁１０ａへの組立と下側の胴縁１０ｂへの組立とは、上下を反転すれば同一であるため、添え字「ａ、ｂ」を省略して下側の胴縁１０ｂについて説明する。 (Assembly of fence-1)

Corresponds to (a) of FIG. 6, (b) and (c) of FIG. 5 correspond to (c) of FIG. 6, respectively, and (b) of FIG. 6 shifts from (a) to (b) of FIG. Showing the way to do. The assembly to the upper trunk edge 10a and the assembly to the lower trunk edge 10b are the same if they are turned upside down, so the subscript “a, b” is omitted and the lower trunk edge 10b is omitted. Will be described.

図５の（ａ）および図６の（ａ）において、胴縁１０の内部に支持材２０が配置され、胴縁１０の端部に組み立て軸１４が当接している。組み立て軸１４は胴縁１０の貫通孔１２に挿入された組み立て用ボルト１３によって、胴縁１０から抜け出し不能に支持されている。したがって、支持材２０は、胴縁１０から抜け出す方向（図６において右方向）の力が作用しても移動することがない。
そして、胴縁１０の挿入孔１１に縦部材３０が斜めに挿入されている。このとき、縦格子３０の側面が、支持材２０の凸部２１に近接または当接している。 5A and 6A, the support member 20 is disposed inside the trunk edge 10, and the assembly shaft 14 is in contact with the end of the trunk edge 10. The assembly shaft 14 is supported by an assembly bolt 13 inserted into the through-hole 12 of the trunk edge 10 so as not to come out of the trunk edge 10. Therefore, the support member 20 does not move even when a force in the direction of pulling out from the trunk edge 10 (the right direction in FIG. 6) is applied.
The vertical member 30 is inserted obliquely into the insertion hole 11 of the trunk edge 10. At this time, the side surfaces of the vertical lattice 30 are close to or in contact with the convex portions 21 of the support member 20.

図６の（ｂ）において、胴縁１０に斜めに挿入された縦部材３０を起立させている（胴縁１０の長手方向と縦部材３０の軸方向とを垂直にする）。このとき、胴縁１０の挿入孔１１の縁が傾動支点となって、縦部材３０は容易に傾動し、かかる傾動によって、縦部材３０の側面は支持材２０の凸部２１に摺動しながら、支持材２０を押し広げている。 In FIG. 6B, the longitudinal member 30 inserted obliquely into the trunk edge 10 is erected (the longitudinal direction of the trunk edge 10 and the axial direction of the longitudinal member 30 are perpendicular). At this time, the edge of the insertion hole 11 of the trunk edge 10 serves as a tilting fulcrum, and the vertical member 30 easily tilts, and the side surface of the vertical member 30 slides on the convex portion 21 of the support member 20 by such tilting. The support material 20 is spread out.

図５の（ｂ）および図６の（ｃ）において、縦部材３０はさらに傾動しているから、縦格子３０の貫通孔３１に支持材２０の凸部２１が係止（陥没）すると共に、支持材２０はスプリングバックしてその幅が元に戻っている。
すなわち、支持材２０の凸部２１は、断面円弧状の縦部材３０の側面を軸方向に対して垂直の面内で登って貫通孔３１に陥没したことになる。このため、陥没した後に、縦部材３０の軸方向に向かって貫通孔３１から抜け出そうとすると、支持材２０を陥没直前の幅以上に大きく拡げる必要が生じる。すなわち、支持材２０の凸部２１は、縦部材３０の貫通孔３１から容易に抜け出さないことになる。 In (b) of FIG. 5 and (c) of FIG. 6, since the vertical member 30 is further tilted, the convex portion 21 of the support member 20 is locked (depressed) in the through hole 31 of the vertical lattice 30. The support member 20 is springback and its width is restored.
That is, the convex portion 21 of the support member 20 is recessed in the through hole 31 by climbing the side surface of the vertical member 30 having an arcuate cross section in a plane perpendicular to the axial direction. For this reason, if it tries to escape from the through-hole 31 toward the axial direction of the vertical member 30 after sinking, it will be necessary to expand the support material 20 more than the width | variety just before sinking. That is, the convex portion 21 of the support member 20 does not easily come out of the through hole 31 of the vertical member 30.

図５の（ｃ）において、縦部材３０を起立させている。このとき、支持剤２０の端面は組み立て治具１４から離れているから、組み立て治具１４および組み立て用ボルト１３を容易に撤去することができる。
そして、胴縁１０の両端部を、それぞれ支柱３に設置することにより、柵１が完成する（図示しない）。 In FIG. 5C, the vertical member 30 is erected. At this time, since the end surface of the support 20 is separated from the assembly jig 14, the assembly jig 14 and the assembly bolt 13 can be easily removed.
And the fence 1 is completed by installing the both ends of the trunk edge 10 in the support | pillar 3, respectively (not shown).

以上は、縦格子３０が支持材２０に対して垂直（胴縁１０に対して垂直に同じ）に組み立てられる場合を示しているが、図５の（ｂ）に示す工程の後、縦格子３０を支持材２０の長手方向に対して所望の角度に傾斜することができる。このとき、凸部２１が球面の一部であって、貫通孔３１が円形であるから、所望の角度に容易に傾斜することができると共に、何れの角度に傾斜しても、凸部２１は貫通孔３１から抜け出し難くなっている。 The above shows the case where the vertical grid 30 is assembled perpendicularly to the support member 20 (the same as the vertical to the trunk edge 10), but after the step shown in FIG. Can be inclined at a desired angle with respect to the longitudinal direction of the support member 20. At this time, since the convex portion 21 is a part of a spherical surface and the through hole 31 is circular, the convex portion 21 can be easily inclined to a desired angle, and the convex portion 21 can be inclined at any angle. It is difficult to get out of the through hole 31.

よって、支持材２０は縦格子３０によって確実に把持された状態になるため、胴縁１０から抜け出すことがない。また、当該把持部には間隙（ガタ）がないため、縦格子３０がガタつくことがない。さらに、前述のように、支持材２０は胴縁１０に４点で当接しているから支持材２０を引き出すような力が作用しても、支持材２０を把持している縦格子３０は持ち上げられないから、縦格子３０のガタつきは最少に抑えられている。 Therefore, since the support member 20 is securely held by the vertical lattice 30, it does not come out of the trunk edge 10. Further, since there is no gap (backlash) in the grip portion, the vertical lattice 30 does not play back. Further, as described above, since the support member 20 is in contact with the trunk edge 10 at four points, the vertical lattice 30 holding the support member 20 is lifted even if a force that pulls out the support member 20 is applied. Therefore, the backlash of the vertical lattice 30 is minimized.

特に、貫通孔３１に一旦係止（嵌入）した凸部２１は、支持材２０の長手方向には極めて抜け出し難くなっている。すなわち、平面板上を転がった球体が、平面板に設けた丸孔に係止（嵌入）した場合、丸孔から抜け出すために球体を平面板と平行に押す力は、何れの方向でも同じ大きさになる。一方、平面板でなく円筒に丸孔が設けられている場合、丸孔から抜け出すために球体を円筒の軸方向に押す力は、円筒の軸に垂直面で外面に接する方向に押す力に比較して格段に大きなものになるからである。 In particular, the convex portion 21 once locked (inserted) in the through hole 31 is very difficult to come out in the longitudinal direction of the support member 20. That is, when a sphere rolling on a plane plate is locked (inserted) into a round hole provided in the plane plate, the force that pushes the sphere parallel to the plane plate to get out of the round hole is the same in any direction. It will be. On the other hand, when a round hole is provided in a cylinder instead of a flat plate, the force that pushes the sphere in the axial direction of the cylinder in order to get out of the round hole is compared with the force that pushes the sphere in a direction perpendicular to the cylinder axis and in contact with the outer surface. Because it will be much bigger.

なお、以上は胴縁１０や縦格子が丸鋼管によって形成された場合を示しているが本発明はこれに限定するものではなく、ステンレス管、アルミニウム管、その他金属（合金を含む）管、または樹脂管であってもよい。
また、胴縁１０は断面角形状や断面異形状であってもよい。さらに、胴縁１０ａと胴縁１０ｂとが同一形状である場合を示しているが本発明はこれに限定するものではなく、胴縁１０ａと胴縁１０ｂとが異なった形状（外径、断面形状）であってもよい。
さらに、胴縁１０ａ内に配置される支持材２０ａ、２０ｂの凸部の形状と胴縁１０ｂに配置される支持材２０ｃ、２０ｄの凸部の形状とが相違する場合には、縦格子３０の両端部には、それぞれ相違する形状の貫通孔または凹部が形成されてもよい。 In addition, although the above has shown the case where the trunk edge 10 and the vertical lattice are formed of round steel pipes, the present invention is not limited to this, and stainless steel pipes, aluminum pipes, other metal (including alloys) pipes, or A resin tube may be used.
Further, the trunk edge 10 may have a cross-sectional angular shape or a cross-sectional irregular shape. Furthermore, although the case where the trunk edge 10a and the trunk edge 10b have the same shape is shown, the present invention is not limited to this, and the trunk edge 10a and the trunk edge 10b have different shapes (outer diameter, cross-sectional shape). ).
Furthermore, when the shape of the convex portions of the support members 20a and 20b disposed in the trunk edge 10a is different from the shape of the convex portions of the support members 20c and 20d disposed on the trunk edge 10b, Through holes or recesses having different shapes may be formed at both ends.

（柵の組立−２）
図７は本発明の実施形態１に係る柵の組立要領を工程を追って説明する、（ａ）および（ｂ）は部分側面図、（ｃ）は側面視の部分断面図である。なお、上側の胴縁１０ａへの組立と下側の胴縁１０ｂへの組立とは、上下を反転すれば同一であるため、添え字「ａ、ｂ」を省略して下側の胴縁１０ｂについて説明する。
図７の（ａ）において、胴縁１０の内部に支持材２０が配置されている。このとき、支持材２０の断面コ字形状はスプリングバックして、隅部２７と側縁２５との４点（正確には４条）において胴縁１０の内面に当接している。
そして、縦格子３０の貫通孔３１が支持材２０の長手方向（胴縁１０の長手方向に同じ）になるように配置して、縦格子３０を胴縁１０の挿入孔１１に挿入しようとしている。
このとき、支持材２０の側縁２５同士の間隔が縦格子３０の外径よりも大きいから、縦格子３０は支持材２０の一対の側面部２６の間に容易に挿入することになる。 (Assembly of fence-2)
FIGS. 7A and 7B illustrate steps for assembling the fence according to the first embodiment of the present invention, step by step, (a) and (b) being a partial side view, and (c) being a partial sectional view in side view. The assembly to the upper trunk edge 10a and the assembly to the lower trunk edge 10b are the same if they are turned upside down, so the subscript “a, b” is omitted and the lower trunk edge 10b is omitted. Will be described.
In FIG. 7A, the support member 20 is disposed inside the trunk edge 10. At this time, the U-shaped cross section of the support member 20 is spring-backed and is in contact with the inner surface of the trunk edge 10 at four points (exactly four) of the corner 27 and the side edge 25.
Then, the through holes 31 of the vertical lattice 30 are arranged so as to be in the longitudinal direction of the support member 20 (the same as the longitudinal direction of the trunk edge 10), and the vertical lattice 30 is to be inserted into the insertion hole 11 of the trunk edge 10. .
At this time, since the interval between the side edges 25 of the support member 20 is larger than the outer diameter of the vertical lattice 30, the vertical lattice 30 is easily inserted between the pair of side surface portions 26 of the support member 20.

そして、さらに縦格子３０が挿入すると、縦格子３０の角部３７は、支持材２０の凸部２１の裾野に当接し、凸部２１に摺動しながら支持材２０を押し広げる（図示しない）。やがて、縦格子３０の角部３７が凸部２１の頂上に到達した後は、側面３６が凸部２１の頂上に摺動しながら挿入を続ける。
図７の（ｂ）において、縦格子３０はさらに挿入して貫通孔３１が支持材２０の凸部２１と同じ位相（高さ）になっている。このとき、凸部２１の頂上同士の距離は最大幅に押し広げられ、縦格子３０の外径に等しくなっている。 When the vertical lattice 30 is further inserted, the corners 37 of the vertical lattice 30 abut against the skirt of the convex portion 21 of the support member 20 and push the support member 20 while sliding on the convex portion 21 (not shown). . Eventually, after the corner portion 37 of the vertical lattice 30 reaches the top of the convex portion 21, the side surface 36 continues to be inserted while sliding on the top of the convex portion 21.
In FIG. 7B, the vertical lattice 30 is further inserted so that the through holes 31 have the same phase (height) as the convex portions 21 of the support member 20. At this time, the distance between the tops of the convex portions 21 is expanded to the maximum width and is equal to the outer diameter of the vertical lattice 30.

図７の（ｃ）において、縦格子３０を軸心を中心に９０度回転している。すなわち、縦格子３０の貫通孔３１と支持材２０の凸部２１とが同一位置になるため、支持材２０は押し広げられていた支えを失ってスプリングバックするから、支持材２０の凸部２１は縦格子３０の貫通孔３１に係止（嵌入）することになる。
そして、そして、胴縁１０の両端部が、それぞれ支柱３に設置されることにより、柵１が完成する。 In FIG. 7C, the vertical lattice 30 is rotated 90 degrees about the axis. That is, since the through holes 31 of the vertical lattice 30 and the projections 21 of the support member 20 are in the same position, the support member 20 loses the spread support and springs back. Is locked (inserted) into the through holes 31 of the vertical lattice 30.
And the fence 1 is completed by installing the both ends of the trunk edge 10 in the support | pillar 3, respectively.

したがって、前記「柵の組立−１」と同様に、縦格子３０を支持材２０の長手方向に対して所望に角度に傾斜することができ、る縦格子３０のガタつきは最少に抑えられ、さらに、支持材２０の長手方向には極めて抜け出し難くなっている。 Therefore, similarly to the above-mentioned “assembly of the fence-1”, the vertical lattice 30 can be inclined at a desired angle with respect to the longitudinal direction of the support member 20, and the play of the vertical lattice 30 is minimized. Furthermore, it is very difficult to come out in the longitudinal direction of the support member 20.

なお、以上は胴縁１０や縦格子が丸鋼管によって形成された場合を示しているが本発明はこれに限定するものではなく、ステンレス管、アルミニウム管、その他金属（合金を含む）管、または樹脂管であってもよい。
また、胴縁１０は断面角形状や断面異形状であってもよく、縦格子は断面楕円であってもよい。さらに、胴縁１０ａと胴縁１０ｂとが同一形状である場合を示しているが本発明はこれに限定するものではなく、胴縁１０ａと胴縁１０ｂとが異なった形状（外径、断面形状）であってもよい。
さらに、胴縁１０ａ内に配置される支持材２０ａ、２０ｂの凸部の形状と胴縁１０ｂに配置される支持材２０ｃ、２０ｄの凸部の形状とが相違する場合には、縦格子３０の両端部には、それぞれ相違する形状の貫通孔または凹部が形成されてもよい。 In addition, although the above has shown the case where the trunk edge 10 and the vertical lattice are formed of round steel pipes, the present invention is not limited to this, and stainless steel pipes, aluminum pipes, other metal (including alloys) pipes, or A resin tube may be used.
Further, the trunk edge 10 may have an angular cross section or an irregular cross section, and the vertical lattice may have an elliptical cross section. Furthermore, although the case where the trunk edge 10a and the trunk edge 10b have the same shape is shown, the present invention is not limited to this, and the trunk edge 10a and the trunk edge 10b have different shapes (outer diameter, cross-sectional shape). ).
Furthermore, when the shape of the convex portions of the support members 20a and 20b disposed in the trunk edge 10a is different from the shape of the convex portions of the support members 20c and 20d disposed on the trunk edge 10b, Through holes or recesses having different shapes may be formed at both ends.

［実施形態２：柵用パネル］
（全体構成）
本発明の実施形態２に係る柵用パネルは、実施形態１に係る柵１から支柱３を除いたものに同じであるため、図示および各構成部材の説明を省略する。
すなわち、かかる柵用パネルは、これが設置される支柱を限定するものではないため、たとえば、古い柵用パネルを更新する際の「新しい柵用パネル」として既設の支柱に設置されたり、建築物の外壁等の構造物に設置されたりすることも可能である。 [Embodiment 2: Panel for fence]
(overall structure)
Since the fence panel according to the second embodiment of the present invention is the same as the fence 1 according to the first embodiment except for the support column 3, the illustration and description of each component member are omitted.

本発明は以上の構成であるから、任意の傾きの傾斜地に設置することが可能であると共に、設置現場における施工が容易で、簡素な構成であるため製造コストが安価で、さらに、組立後のガタが最少に抑えられるから、平坦地や傾斜地に設置される柵および柵用パネルとして広く利用することができる。 Since the present invention has the above-described configuration, it can be installed on a slope with an arbitrary inclination, is easy to install on the installation site, and has a simple configuration, so that the manufacturing cost is low. Since the backlash is minimized, it can be widely used as a fence and a fence panel installed on a flat or sloping ground.
