Description

本発明は、スライダー部とスライダー収納部と取付具との組み合せに関する。 The present invention relates to a combination of a slider portion, a slider storage portion, and a fixture.

建設現場において、ボルト、工具等の敷地外への落下防止のために建築物の外側構面に垂直ネットが設置されることがある。垂直ネットは鉄骨柱間に張った被覆ワイヤーに取り付けられるが、鉄骨梁が取り付けられていないと隣接する鉄骨柱間に被覆ワイヤーを架け渡すことが困難であり、また、鉄骨梁架設作業の障害になるおそれがあるため、垂直ネットは鉄骨梁を架設した後に設置されることが多い。
鉄骨建方作業において、外周部の鉄骨梁を取り付ける際には垂直ネットが設置されていないため、ボルトや工具等が落下すると、建設敷地内のみならず、外部に落下することがあり、工事関係者だけでなく、歩行者や通行車両等の第三者にとっても危険であった。 At a construction site, a vertical net may be installed on the outer structure of the building to prevent bolts, tools, etc. from falling outside the site. The vertical net is attached to the covering wire stretched between the steel columns, but if the steel beam is not attached, it is difficult to bridge the covering wire between the adjacent steel columns, and it becomes an obstacle to the steel beam erection work. Vertical nets are often installed after the steel beams have been erected because of the risk of this.
In steel frame construction work, a vertical net is not installed when attaching the steel beam on the outer circumference, so if bolts or tools fall, they may fall not only inside the construction site but also outside, which is related to construction work. It was dangerous not only for people but also for third parties such as pedestrians and passing vehicles.

特許文献１には、鉄骨梁を取り付ける前に垂直ネットを設置する垂直ネット先行設置工法を提供する発明が記載されており、垂直ネット先行設置工法は、「鉄骨柱の頂部に、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り付ける工程（第１の工程）、図９を参照」と「前記鉄骨柱を、前記固定部が外側となるように建て込む工程（鉄骨柱建込み工程）」とからなる。そして、「垂直ネットが固定された棒部材の両端それぞれを、隣接する前記鉄骨柱の前記固定部に取り付ける工程（第２の工程），図１０を参照」とからなる。
第１の工程は、鉄骨柱が地上にある場合に、地上で手作業により行うことができるが、
鉄骨柱建込み工程は、改良を必要としない工程（図１１を参照）である。
第２の工程は、鉄骨柱建込み工程の後の工程で鉄骨柱を建て込んだ後であり、建て込んだ鉄骨柱は地上にはないため、地上での手作業により安全かつ簡便に行うことは到底できないという従来技術の欠点を有していた（図１０を参照）。
また、垂直ネットが固定された棒部材の両端それぞれを、隣接する前記鉄骨柱の前記固定部に取り付ける工程（第２の工程）は、クレーン等の重機を必要とするので、地上でかつ手作業にて安全かつ簡便に行うことはできないという従来技術の欠点を有していた（図１０を参照）。
さらに、「鉄骨柱の頂部に、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り付ける工程（第１の工程）」を採用すると、鉄骨柱の頂部に、垂直ネット設置治具を溶接等で取り付ける必要があり、かつ、鉄骨柱Ｐ上に上節柱となる別の鉄骨柱を接合するためには、鉄骨柱の頂部に取付けられた、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り除く工程が必要となるが、当該、鉄骨柱の頂部に取付けられた、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り除く工程は、クレーン等の重機を必要とし、鉄骨柱の頂部に、溶接等で取付けられた垂直ネット設置治具を取り除くことは煩雑であり、地上でかつ手作業にて安全かつ簡便に行うことはできないという従来技術の欠点を有していた（図１２を参照）。
上記［背景技術］については、特開２０１６−２１１２３４号公報に記載の［背景技術］を参照した。
発明者は、かかる従来技術の欠点に鑑み鋭意研究した結果、本発明を完成させた。 Patent Document 1 describes an invention that provides a vertical net pre-installation method for installing a vertical net before attaching a steel beam, and the vertical net pre-installation method is described as "at the top of the steel column, the steel column A step of attaching a vertical net installation jig having a fixing portion protruding from the outer periphery (first step), see FIG. 9 "and a step of building the steel frame column so that the fixing part is on the outside (steel frame column). Building process) ”. Then, it is composed of "a step of attaching both ends of the rod member to which the vertical net is fixed to the fixed portion of the adjacent steel frame column (second step), see FIG. 10".
The first step can be performed manually on the ground when the steel columns are on the ground,
The steel column building process is a process that does not require improvement (see FIG. 11).
The second step is after the steel column is built in the process after the steel column building process, and since the built steel column is not on the ground, it should be done safely and easily by manual work on the ground. Had a drawback of the prior art that it could never be done (see FIG. 10).
Further, the step of attaching both ends of the rod member to which the vertical net is fixed to the fixed portion of the adjacent steel column (second step) requires a heavy machine such as a crane, so that it is manually performed on the ground. It had a drawback of the prior art that it could not be carried out safely and easily (see FIG. 10).
Further, if the "step of attaching a vertical net installation jig having a fixing portion protruding from the outer periphery of the steel column to the top of the steel column (first step)" is adopted, the vertical net is installed on the top of the steel column. It is necessary to attach the tool by welding or the like, and in order to join another steel column to be the upper node column on the steel column P, it protrudes from the outer circumference of the steel column attached to the top of the steel column. A step of removing the vertical net installation jig having a fixed portion is required, but the step of removing the vertical net installation jig having a fixed portion protruding from the outer periphery of the steel column attached to the top of the steel column is , A heavy machine such as a crane is required, and it is complicated to remove the vertical net installation jig attached to the top of the steel column by welding, etc., and it cannot be done safely and easily on the ground and manually. It had the drawbacks of the prior art (see FIG. 12).
For the above [background technique], the [background technique] described in JP-A-2016-21234 is referred to.
The inventor has completed the present invention as a result of diligent research in view of the drawbacks of the prior art.

○外管２１とは、スライダー収納部２０の構成要素であって、スライダー部１０の構成要素である内管１１の一部を伸縮可能に収納する。
外管２１には、内管１１が外管２１に対して伸縮可能なように、距離２ΔＬ（ｃｍ）離れた２つのストッパー穴ｈ２が貫通されてなる。
○スライダー収納部２０（単に、「収納部２０」ともいう。）とは、本発明の構成要素であって、外管２１と垂直板２２とからなり、垂直板２２と外管２１とは（溶接等により）接合されてなる。

スライダー収納部２０（左側タイプ）は、スライダー部１０を左側に取付けてなり、スライダー収納部２０（右側タイプ）は、スライダー部１０を右側に取付けてなり、スライダー収納部２０（両側タイプ）は、スライダー部１０を左右両側に取付けてなる。
○角柱Ｐは、鉄骨材（角パイプ）を垂直に建てて建築物の支え（ささえ）としたものをいう。
○取付具３０とは、本発明の構成要素であって、スライダー部１０とスライダー収納部２０を角柱Ｐに取付けるための手段をいい、垂直板２２が収納される垂直板収納凹部３１を有する。
より具体的には、取付具３０は、高さＨ（ｃｍ）の角柱接触板３０１、角柱接触板３０１と直交する側板３０２と角柱接触板３０１と平行な前面板３０３からなると共に、

○伸縮調節穴ｈ１とは、内管１１に、距離ΔＬ（ｃｍ）毎に対応して貫通されてなる伸縮調節穴をいい、内管１１が外管２１に対して、距離ΔＬ（ｃｍ）毎に伸縮可能なように調節される。
伸縮調節穴ｈ１とストッパー穴ｈ２は内径は同じであるが、隣接する前者同士の離隔距離が離ΔＬ（ｃｍ）であるのに対して、隣接する後者同士の離隔距離が離２ΔＬ（ｃｍ）であるので離隔距離は２倍相違する。
この理由は、後述の＜内管１１が外管２１に対して伸び切った状態において、２つのストッパー穴ｈ２の離隔距離が大きくしてある理由＞…図１４を参照を参照すれば、ストッパー穴ｈ２の離隔距離が大きくすることによって、垂直ネット荷重Ｑ（ｋｇ重）に起因してストッパー穴ｈ２に作用する荷重Ｑ１（ｋｇ重）、荷重Ｑ２（ｋｇ重）を少なくなるからである。
隣接する伸縮調節穴ｈ１同士の離隔距離を小さくするのは、内管１１の伸縮量を細かく調節できるようにするためである。
内管１１の伸縮調節穴ｈ１は、内管１１を伸ばしていけば、外管２１から露出するのに対して（伸ばし切った状態では、内管１１の伸縮調節穴ｈ１が外管２１から露出する。）、内管１１のストッパー穴ｈ２は外管２１の中に収納されたままであるという相違点がある。
○リベットピンｌｐとは、内管１１の伸縮調節穴ｈ１又はストップ穴ｈ２と外管２１のストップ穴ｈ２の位置を合わせ両穴に差し込んで内管１１と外管２１の位置を固定する部品である。

○スナップピンｓｐとは、取付具３０からスライダー収納部２０が抜け出るのを防止するために、スナップピン穴ｐ３に挿入する部品である。
○内管１１のストッパー穴ｈ２、外管２１のストッパー穴ｈ２について
（１）内管１１が、外管２１に対して伸縮可能な場合
内管１１の外管２１に対する位置が調節可能になるように、離隔距離ΔＬ（ｃｍ）毎離れた内管１１の２つの伸縮調節穴ｈ１（２つの伸縮調節穴ｈ１の離隔距離は、２ΔＬ（ｃｍ）である。）と離隔距離２ΔＬ（ｃｍ）離れた外管２１の２つのストッパー穴ｈ２の中心が合わされ、リベットピンｌｐを挿入して一対の穴の位置が固定される。
（２）内管１１が、外管２１に対して伸び切った場合
内管１１の縮む側の２つのストッパー穴ｈ２と外管２１の２つのストッパー穴ｈ２の中心が合わされ、リベットピンｌｐを挿入して一対の穴の位置が固定される（図１４）。
○垂直板２２が垂直板収納凹部３１に収納された場合について
垂直板２２が垂直板収納凹部３１収納された場合、垂直板２２が垂直板収納凹部３１を貫通してなるとともに、垂直板２２の下端のスナップピン穴ｈ３にスナップピンｐ３を挿入してなる（図示せず。）。
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
＜記号の説明＞
○ΔＬ（ｃｍ）とは、内管１１の位置が、外管２１に対して、伸縮可能な距離又は長さ（ｃｍ）をいい、ΔＬ（ｃｍ）毎に伸縮可能である。
ΔＬ（ｃｍ）とは、内管１１の隣接する伸縮調節穴ｈ１同士の離隔距離をいう。また、内管１１の隣接する伸縮調節穴ｈ１とストッパー穴ｈ２の離隔距離をいう。
すなわち、内管１１に伸縮調節穴ｈ１が、距離ΔＬ（ｃｍ）毎に貫通されてなり、外管２１に伸縮調節穴ｈ１が、距離ΔＬ（ｃｍ）毎に対応して貫通されてなる。
さらに、内管１１の縮まる側に２つのストッパー穴ｈ２の離隔距離が２ΔＬ（ｃｍ）に貫通されてなり、外管２１にストッパー穴ｈ２の離隔距離が２ΔＬ（ｃｍ）に貫通されてなり）、内管１１のストッパー穴ｈ２は、外管２１にストッパー穴ｈ２に位置対応して収納される。
○２ΔＬ（ｃｍ）とは、内管１１のストッパー穴ｈ２の離隔距離をいう。
２ΔＬ（ｃｍ）とは、外管２１のストッパー穴ｈ２の離隔距離をいう。
○Ｈ（ｃｍ）とは、取付具３０を構成する、角柱接触板３０１、角柱接触板３０１と直交する側板３０２と角柱接触板３０１と平行な前面板３０３の高さが共に、Ｈ（ｃｍ）である。
上記の場合、取付具３０は一辺がＨ（ｃｍ）の板から、角柱接触板３０１と側板３０２と前面板３０３の境界線で山折り又は谷折りされて、製造される。
＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊＊
＜内管１１が外管２１に対して伸び切った状態において、２つのストッパー穴ｈ２の離隔距離が大きくしてある理由＞…図１４を参照
内管１１には、２又は３以上の伸縮調節穴ｈ１と２つのストッパー穴ｈ２が貫通されてなり、伸縮調節穴ｈ１は、伸縮調節穴ｈ１同士の離隔距離ΔＬ（ｃｍ）毎に貫通されてなる。
伸縮調節穴ｈ１とストッパー穴ｈ２の離隔距離は、ΔＬ（ｃｍ）であるが、２つのストッパー穴ｈ２の離隔距離は、２ΔＬ（ｃｍ）と、伸縮調節穴ｈ１同士の離隔距離ΔＬ（ｃｍ）よりも、大きくしてある。
一方、外管２１には、２つのストッパー穴ｈ２が１対（図４（Ａ）図又は図４（Ｂ）図）又は２対（図３）貫通されてなり、２つのストッパー穴ｈ２の離隔距離は、２ΔＬ（ｃｍ）と大きくしてある。
内管１１の２つのストッパー穴ｈ２が、外管２１の２つのストッパー穴ｈ２の位置が一致するように外管２１の中に納まるようにしてある。内管１１の２つのストッパー穴ｈ２と外管２１の２つのストッパー穴ｈ２に、リベットピンｌｐを挿入して内管１１と外管２１が伸縮制限されてなる。
２つのストッパー穴ｈ２の離隔距離が大きくしてある理由は、
内管１１のネット取付具１２には、垂直ネットの（自重）荷重Ｑ（ｋｇ重）が作用し、この荷重をストッパー穴ｈ２に作用する荷重Ｑ１（ｋｇ重）と荷重Ｑ２（ｋｇ重）で支える。
荷重Ｑ２（ｋｇ重）が作用するストッパー穴ｈ２の回りのモーメントの釣合と垂直方向の力の釣合を考えれば、下式が成立する。
Ｑ×ΔＬ×９＝Ｑ１×２ΔＬ……（Ａ）式
Ｑ＋Ｑ１＝Ｑ２……（Ｂ）式
Ａ）式、（Ｂ）式より、Ｑ１＝４．５Ｑ、Ｑ２＝５．５Ｑとなる。
ストッパー穴ｈ２に作用する荷重Ｑ１（ｋｇ重）と荷重Ｑ２（ｋｇ重）はかなり大きな値である。
２つのストッパー穴ｈ２の離隔距離は、２ΔＬ（ｃｍ）をΔＬ（ｃｍ）とすれば、Ｑ１＝９Ｑ、Ｑ２＝１０Ｑとなる。
すなわち、内管１１が外管２１に対して伸び切った状態における強度面の安全性を向上させるためには、内管１１が外管２１に対して伸び切った状態において、２つのストッパー穴ｈ２の離隔距離が大きくする必要がある。

＜鉄骨構造工程の説明＞
Ｓ１：鉄骨柱（角柱）が地上にある場合において、先行設置手段を使用して垂直ネットを設置する工程
鉄骨柱（角柱）を建て込む前であって、かつ、鉄骨柱（角柱）が地上にある場合において、鉄骨柱（角柱）を建て込む前に地上において、クレーン等の重機を使用することなく全て手作業で先行設置手段を使用して垂直ネットを設置することによって、安全かつ簡便に、鉄骨柱（角柱）を建て込む前に垂直ネットを鉄骨柱（角柱）に設置する先行設置手段を提供すること（すなわち、本発明の第１〜第３課題）を達成することができた。
Ｓ２：鉄骨柱（角柱）建込み工程
先行設置手段を使用して地上において垂直ネットを設置した鉄骨柱（角柱）を、地上において鉄骨柱に取付けた取付部が外側（建物外構側）となるように建て込む。当該工程は、従来と違って、垂直ネットを設置した鉄骨柱をクレーンで吊って建て込む。
鉄骨柱（角柱）建込み工程が完了した場合には、垂直ネットは既に鉄骨柱に設置されている。
Ｓ３：前記垂直ネットの内部で、鉄骨梁を架設する工程
鉄骨柱に鉄骨梁を架設する前に、Ｓ２：鉄骨柱（角柱）建込み工程において、垂直ネットを地上で設置することができる。垂直ネットを設置した後に鉄骨梁を架設するため、鉄骨梁架設時にボルトや工具等が落下しても、建設敷地外の歩行者や通行車両の上に落下することはない。
Ｓ４：前記鉄骨柱にワイヤーを取り付け、前記垂直ネットを前記棒部材から前記ワイヤーに付け替える工程
鉄骨梁Ｂを架設した鉄骨柱Ｐの被覆ワイヤー用フックに被覆ワイヤーを取り付け、垂直ネットをスライダー部１０から被覆ワイヤーに付け替える。
Ｓ５：スライダー部１０とスライダー収納部２０とを前記鉄骨柱から取り外す工程
垂直ネット４が取り外されたスライダー部１０とスライダー収納部２０とを鉄骨柱２から手作業で取り外し、クレーンで吊り下ろす。従来用いられている被覆ワイヤーに垂直ネットを付け替え、スライダー部１０を取り除くこと、及び、鉄骨柱Ｐからスライダー収納部２０を取り外すことで、次の鉄骨柱（角柱）建込み工程において、再使用することができ省資源、省エネルギーに貢献し、コスト低減を図ることができる。
このようにして、鉄骨柱Ｐ上に上節柱となる別の鉄骨柱を接合することができる。この別の鉄骨柱に本発明の垂直ネット先行設置工法を適用しながら、鉄骨柱を積み上げることにより、高層建築物を建設することができる。

以下、本発明に係る、スライダー部１０とスライダー収納部２０と取付具３０との組み合せ１００に関する最良の実施形態について、図面を参照しながら説明する。
［図１］図１は、本発明に係る、スライダー部１０を表す図面である。（Ａ）図は、スライダー部１０（右側タイプ）を表す平面図である。（Ｂ）図は、スライダー部１０（右側タイプ）を表す正面図である。

［図３］図３は、本発明に係る、スライダー収納部２０を表す図面である。（Ａ）図は、スライダー収納部２０（両側タイプ）を表す平面図である。（Ｂ）図は、スライダー収納部２０（両側タイプ）を表す正面図である。
［図４］図４は、本発明に係る、スライダー収納部２０を表す図面である。（Ａ）図は、スライダー収納部２０（左側タイプ）を表す正面図である。（Ｂ）図は、スライダー収納部２０（右側タイプ）を表す正面図である。
［図５］図５は、本発明に係る、取付具３０を表す図面である。（Ａ）図は、取付具３０を表す平面図である。（Ｂ）図は、取付具３０を表す正面図である。
［図６］図６は、鉄骨柱（角柱）が地上にある場合において、本発明に係る、先行設置手段を鉄骨柱（角柱）に設置する工程の状態図を表している。本発明に係る、先行設置手段を鉄骨柱（角柱）に設置する工程は全て地上においてクレーン等の重機を使うことなく手作業にて簡便になされる。取付具３０が、鉄骨柱（角柱）Ｐに、スミ肉溶接等により接合される。スライダー部１０の内管１１の一部を、外管２１に伸縮可能に収納させる。スライダー収納部２０の外管２１に接合されてなる垂直板２２を、取付具３０の垂直板収納凹部３１の中に挿入させて収納する。なお、図７の中に示されたｘｙｚ座標系は、鉄骨柱（角柱）が地上にある場合（横たわった状態である）において、ｘ方向、ｙ方向は、水平方向であり、ｚ方向は垂直（反重力）方向である。鉄骨柱（角柱）が建て込んだ状態では、ｙ方向が垂直方向になり、ｚ方向が水平方向になる（すなわち、紙面視、上方向がｙ方向になる。）。
［図７］図７は、鉄骨柱（角柱）が地上にある場合において、本発明に係る、先行設置手段を鉄骨柱（角柱）に設置した後に、先行設置手段に垂直ネットを取付ける工程の状態図を表している。本発明に係る、先行設置手段に垂直ネットを取付ける工程は全て地上においてクレーン等の重機を使うことなく手作業にて簡便になされる。垂直ネットに取付けられた紐をスライダー部のネット取付具１２を括り付けてることにより、先行設置手段に垂直ネットを取付ける。これにより、鉄骨柱（角柱）Ｐに、スミ肉溶接等により接合される。スライダー部１０の内管１１の一部を、外管２１に伸縮可能に収納させる。スライダー収納部２０の外管２１に接合されてなる垂直板２２を、取付具３０の垂直板収納凹部３１の中に挿入させて収納させる。鉄骨柱（角柱）を建て込む前であって、かつ、鉄骨柱（角柱）が地上にある場合において、鉄骨柱（角柱）を建て込む前に地上において、クレーン等の重機を使用することなく全て手作業で先行設置手段を使用して垂直ネットを設置することによって、安全かつ簡便に、鉄骨柱（角柱）を建て込む前に垂直ネットを鉄骨柱（角柱）に設置する先行設置手段を提供すること（すなわち、本発明の第１課題）を達成することができた。なお、図７の中に示されたｘｙｚ座標系は、鉄骨柱（角柱）が地上にある場合（横たわった状態である）において、ｘ方向、ｙ方向は、水平方向であり、ｚ方向は垂直（反重力）方向である。鉄骨柱（角柱）が建て込んだ状態では、ｙ方向が垂直方向になり、ｚ方向が水平方向になる（すなわち、紙面視、上方向がｙ方向になる。）。
［図８］図８は、建て込んだ鉄骨柱（角柱）に取付ける垂直ネットの必要な範囲の考え方を示す図である。（Ａ）図は、建て込んだ鉄骨柱（角柱）Ｐ’、Ｐの位置関係、及び、垂直ネットの必要な範囲を表す平面図である。建て込んだ鉄骨柱（角柱）Ｐ、Ｐ’は、それぞれ、標準タイプ（コーナータイプでない）鉄骨柱（角柱）、コーナータイプの（コーナーの位置にある）鉄骨柱（角柱）である。（Ｂ）図は、建て込んだ鉄骨柱（角柱）Ｐ’、Ｐの位置関係、及び、垂直ネットの必要な範囲を表す正面図である。垂直ネットの必要な範囲は、鉄骨柱（角柱）Ｐ（標準タイプ）は、幅Ｗ（ｃｍ）の範囲であり、鉄骨柱（角柱）Ｐ’（コーナータイプ）は、幅Ｗ’（ｃｍ）の範囲であり、隙間ΔＷ（ｃｍ）の範囲は、垂直ネットを必要としない。この理由は、鉄骨建方作業において、外周部の鉄骨梁を取り付ける際には垂直ネットが設置されていないため、ボルトや工具等が落下すると、建設敷地内のみならず、外部に落下することがあり、工事関係者だけでなく、歩行者や通行車両等の第三者にとっても危険であったことから分るように、外周部の鉄骨梁を取り付ける際に、ボルトや工具等が落下するのであり、隙間ΔＷ（ｃｍ）の範囲は、ボルトや工具等が落下するおそれがなく、垂直ネットを必要としない。発明者は、隙間ΔＷ（ｃｍ）の範囲は、ボルトや工具等が落下するおそれがなく、垂直ネットを必要としないことに初めて気が付き、鉄骨柱を建て込む前であって、かつ、鉄骨柱が地上にある場合において、鉄骨柱を建て込む前に地上において、垂直ネットをクレーン等の重機を使用することなく全て手作業で設置することによって、安全かつ簡便に、鉄骨梁を取付ける前に設置する垂直ネット先行設置手段を提供するという本発明を想到した。
［図９］図９は、従来技術（［特許文献１］特開２０１６−２１１２３４号公報の図４）の技術内容を開示している。鉄骨柱の頂部に、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り付ける工程（第１の工程）を開示している。
［図１０］図１０は、従来技術（［特許文献１］特開２０１６−２１１２３４号公報の図５）の技術内容を開示している。垂直ネットが固定された棒部材の両端それぞれを、隣接する前記鉄骨柱の前記固定部に取り付ける工程（第２の工程）を開示している。従来技術では、垂直ネットが鉄骨柱の間は、隙間ΔＷ（Ｃｍ）もなく完全に貼られているのに対して、本発明では、垂直ネットが鉄骨柱の間は、隙間ΔＷ（ｃｍ）を許容している。外周部の鉄骨梁を取り付ける作業は鉄骨柱の廻りに限定されるので、隙間ΔＷ（ｃｍ）の範囲ではボルトや工具等が落下するおそれがないからである。
［図１１］図１１は、従来技術（［特許文献１］特開２０１６−２１１２３４号公報の図６）の技術内容を開示している。図１１で開示している鉄骨柱建込み工程は、改良を必要としない工程（図１１を参照）である。
［図１２］図１２は、従来技術（［特許文献１］特開２０１６−２１１２３４号公報の図７）の技術内容を開示している。「鉄骨柱の頂部に、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り付ける工程（第１の工程）」を採用すると、鉄骨柱の頂部に、垂直ネット設置治具を溶接等で取り付ける必要があり、かつ、鉄骨柱Ｐ上に上節柱となる別の鉄骨柱を接合するためには、鉄骨柱の頂部に取付けられた、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り除く工程が必要となるが、当該、鉄骨柱の頂部に取付けられた、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り除く工程は、クレーン等の重機を必要とし、鉄骨柱の頂部に、溶接等で取付けられた垂直ネット設置治具を取り除くことは煩雑であり、地上でかつ手作業にて安全かつ簡便に行うことはできないという従来技術の欠点を有していた。
［図１３］図１３は、請求項２に記載された発明を説明する図面である。図１３の左図は、図４（Ａ）図の、スライダー収納部２０（左側タイプ）を表す正面図である。図１３の右図は、図２（Ａ）図の、スライダー部１０（左側タイプ）を表す正面図である。図１３は、左側のスライダー収納部２０へ右側のスライダー部１０を挿入しようとする状態を表している。内管１１と外管２１が角パイプであって、内管１１が外管２１に対して距離ΔＬ（ｃｍ）毎に伸縮可能なように、内管１１には、２又は３以上の伸縮調節穴ｈ１が距離ΔＬ（ｃｍ）毎に貫通されてなり、外管２１には、２つのストッパー穴ｈ２が距離２ΔＬ（ｃｍ）に貫通されてなる。内管１１の外管２１に対する位置が調節可能になるように、距離ΔＬ（ｃｍ）毎離れた内管１１の２つのストッパー穴ｈ２（図１３では、イとロ）と距離２ΔＬ（ｃｍ）離れた外管２１の２つのストッパー穴ｈ２の中心が合わされ、リベットピンｌｐを挿入して一対の穴の位置が固定される。すなわち、内管１１の管端がストッパー穴ｈ２（ロ）の中心から距離Ｌ０（ｃｍ）の位置に動かないように固定される。
［図１４］図１４は、内管１１が外管２１に対して伸び切った状態を表す図である。内管１１が外管２１に対して伸び切った状態にあっても、ネットの荷重Ｑ（ｋｇ重）によるモーメントを支えるために、（１）２つのストッパー穴ｈ２の離隔距離を２ΔＬ（ｃｍ）とし、伸縮調節穴ｈ１の離隔距離ΔＬ（ｃｍ）より大きくしてある。（２）内管１１の２つのストッパー穴ｈ２が、外管２１の２つのストッパー穴ｈ２の位置が一致するように外管２１の中に納まるようにしてある。内管１１の２つのストッパー穴ｈ２と外管２１の２つのストッパー穴ｈ２に、リベットピンｌｐを挿入して内管１１と外管２１が伸縮制限されてなる。

There is. All the steps of attaching the vertical net to the preceding installation means according to the present invention are simplified manually on the ground without using a heavy machine such as a crane. The vertical net is attached to the preceding installation means by tying the string attached to the vertical net to the net attachment 12 of the slider portion. As a result, it is joined to the steel frame column (square column) P by fillet welding or the like. A part of the inner tube 11 of the slider portion 10 is housed in the outer tube 21 so as to be expandable and contractible.

That (that is, the first problem of the present invention) could be achieved. In the xyz coordinate system shown in FIG. 7, when the steel frame column (square column) is on the ground (lying state), the x direction and the y direction are the horizontal direction, and the z direction is the vertical direction. (Antigravity) direction. In the state where the steel column (square column) is built, the y direction is the vertical direction and the z direction is the horizontal direction (that is, the paper view, the upward direction is the y direction). 図８は、建て込んだ鉄骨柱（角柱）に取付ける垂直ネットの必要な範囲の考え方を示す図である。（Ａ）図は、建て込んだ鉄骨柱（角柱）Ｐ’、Ｐの位置関係、及び、垂直ネットの必要な範囲を表す平面図である。建て込んだ鉄骨柱（角柱）Ｐ、Ｐ’は、それぞれ、標準タイプ（コーナータイプでない）鉄骨柱（角柱）、コーナータイプの（コーナーの位置にある）鉄骨柱（角柱）である。（Ｂ）図は、建て込んだ鉄骨柱（角柱）Ｐ’、Ｐの位置関係、及び、垂直ネットの必要な範囲を表す正面図である。垂直ネットの必要な範囲は、鉄骨柱（角柱）Ｐ（標準タイプ）は、幅Ｗ（ｃｍ）の範囲であり、鉄骨柱（角柱）Ｐ’（コーナータイプ）は、幅Ｗ’（ｃｍ）の範囲であり、隙間ΔＷ（ｃｍ）の範囲は、垂直ネットを必要としない。この理由は、鉄骨建方作業において、外周部の鉄骨梁を取り付ける際には垂直ネットが設置されていないため、ボルトや工具等が落下すると、建設敷地内のみならず、外部に落下することがあり、工事関係者だけでなく、歩行者や通行車両等の第三者にとっても危険であったことから分るように、外周部の鉄骨梁を取り付ける際に、ボルトや工具等が落下するのであり、隙間ΔＷ（ｃｍ）の範囲は、ボルトや工具等が落下するおそれがなく、垂直ネットを必要としない。発明者は、隙間ΔＷ（ｃｍ）の範囲は、ボルトや工具等が落下するおそれがなく、垂直ネットを必要としないことに初めて気が付き、鉄骨柱を建て込む前であって、かつ、鉄骨柱が地上にある場合において、鉄骨柱を建て込む前に地上において、垂直ネットをクレーン等の重機を使用することなく全て手作業で設置することによって、安全かつ簡便に、鉄骨梁を取付ける前に設置する垂直ネット先行設置手段を提供するという本発明を想到した。FIG. 8 is a diagram showing the concept of the required range of the vertical net to be attached to the built-in steel column (square column). The figure (A) is a plan view which shows the positional relationship of the built-in steel column (square column) P', P, and the required range of the vertical net. The built-in steel columns (prisms) P and P'are standard type (non-corner type) steel columns (prisms) and corner type (corner positions) steel columns (prisms), respectively. (B) is a front view showing the positional relationship between the built-in steel columns (square columns) P'and P, and the required range of the vertical net. The required range of the vertical net is that the steel column (prism) P (standard type) has a width W (cm), and the steel column (prism) P'(corner type) has a width W'(cm). It is a range, and the range of the gap ΔW (cm) does not require a vertical net. The reason for this is that in the steel frame construction work, a vertical net is not installed when attaching the steel beam on the outer periphery, so if bolts or tools fall, they may fall not only inside the construction site but also outside. As you can see from the fact that it was dangerous not only for construction personnel but also for third parties such as pedestrians and passing vehicles, bolts and tools will fall when installing the steel beam on the outer circumference. There is no risk of bolts, tools, etc. falling in the range of the gap ΔW (cm), and a vertical net is not required. The inventor first noticed that the range of the gap ΔW (cm) is such that bolts and tools do not fall and does not require a vertical net, and before the steel column is built, and the steel column is When it is on the ground, it is safe and convenient to install the vertical net before installing the steel beam by manually installing the vertical net on the ground before building the steel column without using heavy machinery such as cranes. The present invention has been conceived to provide a means for pre-installing a vertical net. 図９は、従来技術（［特許文献１］特開２０１６−２１１２３４号公報の図４）の技術内容を開示している。鉄骨柱の頂部に、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り付ける工程（第１の工程）を開示している。FIG. 9 discloses the technical contents of the prior art (FIG. 4 of Japanese Patent Application Laid-Open No. 2016-21124). A step (first step) of attaching a vertical net installation jig having a fixing portion protruding from the outer periphery of the steel frame column to the top of the steel frame column is disclosed. 図１０は、従来技術（［特許文献１］特開２０１６−２１１２３４号公報の図５）の技術内容を開示している。垂直ネットが固定された棒部材の両端それぞれを、隣接する前記鉄骨柱の前記固定部に取り付ける工程（第２の工程）を開示している。従来技術では、垂直ネットが鉄骨柱の間は、隙間ΔＷ（ｃｍ）もなく完全に貼られているのに対して、本発明では、垂直ネットが鉄骨柱の間は、隙間ΔＷ（ｃｍ）を許容している。外周部の鉄骨梁を取り付ける作業は鉄骨柱の廻りに限定されるので、隙間ΔＷ（ｃｍ）の範囲ではボルトや工具等が落下するおそれがないからである。FIG. 10 discloses the technical contents of the prior art (FIG. 5 of Japanese Patent Application Laid-Open No. 2016-21234). A step (second step) of attaching both ends of a rod member to which a vertical net is fixed to the fixed portion of the adjacent steel frame column is disclosed. In the prior art, the vertical net is completely attached between the steel columns without a gap ΔW (cm), whereas in the present invention, the vertical net has a gap ΔW (cm) between the steel columns. Tolerate. This is because the work of attaching the steel beam on the outer peripheral portion is limited to the circumference of the steel column, so that there is no possibility that bolts, tools, etc. will fall within the range of the gap ΔW (cm). 図１１は、従来技術（［特許文献１］特開２０１６−２１１２３４号公報の図６）の技術内容を開示している。図１１で開示している鉄骨柱建込み工程は、改良を必要としない工程（図１１を参照）である。FIG. 11 discloses the technical contents of the prior art (FIG. 6 of Japanese Patent Application Laid-Open No. 2016-21234). The steel column building process disclosed in FIG. 11 is a process that does not require improvement (see FIG. 11). 図１２は、従来技術（［特許文献１］特開２０１６−２１１２３４号公報の図７）の技術内容を開示している。「鉄骨柱の頂部に、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り付ける工程（第１の工程）」を採用すると、鉄骨柱の頂部に、垂直ネット設置治具を溶接等で取り付ける必要があり、かつ、鉄骨柱Ｐ上に上節柱となる別の鉄骨柱を接合するためには、鉄骨柱の頂部に取付けられた、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り除く工程が必要となるが、当該、鉄骨柱の頂部に取付けられた、該鉄骨柱の外周から突出する固定部を有する垂直ネット設置治具を取り除く工程は、クレーン等の重機を必要とし、鉄骨柱の頂部に、溶接等で取付けられた垂直ネット設置治具を取り除くことは煩雑であり、地上でかつ手作業にて安全かつ簡便に行うことはできないという従来技術の欠点を有していた。FIG. 12 discloses the technical contents of the prior art (FIG. 7 of Japanese Patent Application Laid-Open No. 2016-21234). When the "step of attaching a vertical net installation jig having a fixing portion protruding from the outer periphery of the steel column to the top of the steel column (first step)" is adopted, the vertical net installation jig is attached to the top of the steel column. It is necessary to attach by welding or the like, and in order to join another steel column to be the upper node column on the steel column P, a fixed portion attached to the top of the steel column and protruding from the outer periphery of the steel column. The step of removing the vertical net installation jig having a fixing portion protruding from the outer periphery of the steel column, which is attached to the top of the steel column, is a step of removing the vertical net installation jig. It is a conventional technique that it is complicated to remove the vertical net installation jig attached to the top of the steel column by welding, etc., and it cannot be safely and easily performed on the ground and manually.

FIG. 13 shows a state in which the slider portion 10 on the right side is to be inserted into the slider storage portion 20 on the left side. The inner pipe 11 and the outer pipe 21 are square pipes, and the inner pipe 11 can be expanded or contracted by 2 or 3 or more so that the inner pipe 11 can be expanded and contracted with respect to the outer pipe 21 by a distance ΔL (cm). The hole h1 is penetrated every distance ΔL (cm), and the outer tube 21 is formed by two stopper holes h2 penetrating the distance 2ΔL (cm). Two stopper holes h2 (a and b in FIG. 13) and a distance of 2ΔL (cm) apart from each other by a distance ΔL (cm) so that the position of the inner pipe 11 with respect to the outer pipe 21 can be adjusted. The centers of the two stopper holes h2 of the outer tube 21 are aligned, and the positions of the pair of holes are fixed by inserting the rivet pin lp. That is, the end of the inner pipe 11 is fixed so as not to move at a distance L0 (cm) from the center of the stopper hole h2 (b). 図１４は、内管１１が外管２１に対して伸び切った状態を表す図である。内管１１が外管２１に対して伸び切った状態にあっても、ネットの荷重Ｑ（ｋｇ重）によるモーメントを支えるために、（１）２つのストッパー穴ｈ２の離隔距離を２ΔＬ（ｃｍ）とし、伸縮調節穴ｈ１の離隔距離ΔＬ（ｃｍ）より大きくしてある。（２）内管１１の２つのストッパー穴ｈ２が、外管２１の２つのストッパー穴ｈ２の位置が一致するように外管２１の中に納まるようにしてある。内管１１の２つのストッパー穴ｈ２と外管２１の２つのストッパー穴ｈ２に、リベットピンｌｐを挿入して内管１１と外管２１が伸縮制限されてなる。FIG. 14 is a diagram showing a state in which the inner pipe 11 is fully extended with respect to the outer pipe 21.
