【0001】
【発明が属する技術分野】
本発明は、鋼板または敷鉄板を互い同志接続する際に、接続部位を2枚1組とするフラットバーをボルト締めすることにより鋼板同士の段差をなくし、敷き鋼板による仮設路への車両の乗り入れを段差なく安全に保つことができるようにした鋼板または敷鉄板の接続方法に関する。
【0002】
【従来の技術】
工事現場の車両導入用スロープや傾斜地に敷く鋼板または敷鉄板は、鋼板等の滑り防止のために、フラットバーを用いて鋼板同士を溶接で固定を行っているが、
傾斜地に敷く鋼板の量にかかわらず、溶接工を手配しなければならないので、工費が嵩むという難点がある。このため、実用新案登録第3283837号では、隣接する敷鉄板の各辺の適当な位置に、互いに対向する鋼板縁部を上下両側から挟み付け可能な複数組の連絡片を備えた連結金具を配置し、連絡片の各端近くにあけたメネジに締付要素(ネジ)を螺合して締付けることにより敷鉄板を接続する方法が提案されている。
【0003】
【発明が解決しようとする課題】
上記のように、連結金具の締め付けによって鋼板同士を接続することができるが、接続強度が弱く、かつ連結金具が鋼板面から25mm程度高く突出するため車両タイヤを損傷するおそれがある。
本発明は、鋼板同士を接続が容易で、車両の乗り入れを段差なく安全に保つことができるようにした鋼板の接続方法を提供することを目的とする。
【0004】
【課題を解決するための手段】
上記目的を達成するため、本発明鋼板の接続方法は、鋼板接続部を挟んで上下2枚のフラットバーを配置し、両フラットバーと鋼板に明けた孔にボルトを通して締付けることを特徴とする。請求項2の発明は、下部フラットバーは第1、第2のタップ孔を有し、上部フラットバーは前記下部フラットバーの第1、第2のタップ孔に合致する位置に第1、第2のボルト通し孔を有していることを特徴とするものである。
【0005】
また、請求項3の発明は、下部フラットバーに凸部を形成し、または第3のボルトを挿入して鋼板に明けた姿勢制御用の孔に挿合するようにし、
鋼板接続時には、上部フラットバーを鋼板縁部と平行に維持すると共に、下部フラットバーは前記姿勢制御用の孔を利用して鋼板縁部に対し直交し、かつ第2のタップ孔を含む下部フラットバーの過半部が鋼板縁部より突出するように仮止めして隣接する鋼板縁部に突き合わせたのち、
前記上部フラットバーを水平面内に旋回することにより鋼板を挟んで上下部フラットバーを重合させてボルト締めする、ことを特徴とするものである。
【0006】
【発明の実施の形態】
本発明は、鋼板10の接続部を上下2枚のフラットバー30、20で挟み、両フラットバーと鋼板に明けた孔にボルト41、42を通して締付けて接続するものである。
図1は本発明方法による鋼板10の接続状態を示す。図1(a)のように、水平地盤から下降傾斜面に鋼板を敷設する場合に、水平地盤の接続部10A、傾斜面上限部分の上に凸の接続部10B、傾斜面上での接続部10Cが現れ、また、図1(b)のように下降傾斜面から水平地盤に鋼板を敷設する場合には、傾斜面上の接続部10C、傾斜面下限部分で上に凹んだ接続部10D及び水平地盤の接続部10Aが現れる。上記水平接続部10A、10Cの詳細は後記図3、4に、上に凸となる接続部10Bは図5に、上に凹んだ接続部10Dは図6に基づいてそれぞれ後述する。
【0007】
鋼板10は、図2の拡大平面図に示すように、一方の長辺4箇所と両短辺各2箇所にそれぞれ外孔11と内孔13(8個所×2=16個の孔)を明け、他方の長辺4箇所に1箇ずつの外孔12(4個所×1=4個の孔)、合計20ケの孔を明けてある。
鋼板の一方の長辺縁部14と、この長辺に直交する両短辺縁部15、15aに上部フラットバー30の第1のボルト通し孔31に挿通したボルト41をルーズに挿合しうる外孔11をあけると共に、下部フラットバー20を鋼板縁と直交させた状態に保持するための姿勢制御用内孔13を設ける。また、他方の長辺縁部14aには、上部フラットバー30の第2のボルト通し孔32に挿通したボルト42をルーズに挿合しうる外孔12を設ける。
なお、鋼板10の一方の長辺縁部14の中央に、クレーンのフック18を掛けるための吊り用長孔17を設けている。
【0008】
下部フラットバー20は、図7(a)断面図、(b)平面図に示すように、第1、第2のタップ孔21、22を有し、上部フラットバー30は図4、8に示すように下部フラットバーのタップ孔21、22に合致する位置に第1、第2のボルト通し孔31、32を有している。
下部フラットバーの3ヶのタップ孔21、22、23を、例えばM16mm、上部フラットバー30のボルト通し孔31,32を17φmmとしたとき、鋼板10の内外の孔11、12、13を22φmmとする。
【0009】
前述したように、鋼板を接続するに際し、下部フラットバー20を鋼板縁と直交する方向に突出させた状態に保持するため、下部フラットバー20に設けた凸部25を、一方の鋼板の外孔11の近くにあけた内孔13に挿合して下部フラットバー20の姿勢を制御する手段が形成されている。
図示例の姿勢制御手段は、下部フラットバー20にあけたタップ孔23にフラットバー下面から第3のボルトを螺合し、このボルト首下を凸部として鋼板の外孔近くにあけた内孔13に挿合するようにしているが、ボルトの代りに下部フラットバー20に凸起部を溶接で成形させ、これを姿勢制御用内孔13に挿合するようにしてもよい。
【0010】
水平地盤上で鋼板を接続する場合には、図3、4に示すように、接続される鋼板10、10の両端部に跨って上下のフラットバー30、20が配置され、上部のフラットバー30のボルト通し孔31、32から挿通したボルト41,42を隣接する鋼板の外孔11、12に通し、下部のフラットバー20のタップ孔21、22にそれぞれ螺合して鋼板接続部をボルト41,42によって締め付け一体化する。
地盤の傾斜面上限における上に凸の接続部10B(図1a)では、上下のフラットバー30、20の中央を地盤の傾斜角と同じ、又はほぼ同じ角度に曲げ加工したものを用意して、上部のフラットバー30のボルト通し孔から挿通したボルト41,42を隣接する鋼板の外孔に通し、下部のフラットバー20のタップ孔21、22にそれぞれ螺合して接続部を一体にボルト締めする(図5)。また、上に凹んだ接続部10D(図1b)では、上下のフラットバー30、20の中央を地盤の傾斜角と同じ、又はほぼ同じ角度に曲げ加工したものを用意し、前同様ボルト41,42を下部のフラットバー20のタップ孔21、22に螺合して接続部を一体にボルト締めする(図6)。
【0011】
鋼板を接続するには、予め鋼板の縁部に上部フラットバー30が鋼板縁部と平行になるように重ねて上部フラットバー30の第1のボルト通し孔31から鋼板の外孔11にボルト41を挿通する(図8)一方、姿勢制御用内孔13に向け下部フラットバー20の下面に設けた凸部25を挿合し(図9)、鋼板縁部に対し直交し、かつ第2のタップ孔22を含む下部フラットバー20の過半部が鋼板縁部より突出するように仮止めする。
上部フラットバー30と下部フラットバー20を組み付けた鋼板10をクレーンにより吊り上げて、さきに敷設された鋼板の端部におろし、バールなどを用いて微調整しながら密着させることにより、突出させた下部フラットバー20の第2のタップ孔22と、被接続鋼板の外孔12とが合致する位置にセットする。図10のように、タップ孔22と外孔12とが距離eだけ芯ズレしているときは、第1のボルト41を少し緩め、シノ(芯合わせ工具)を用いて鋼板の外孔12と下部フラットバーの第2のタップ孔22との芯あわせを行う(図11)。
ついで上部フラットバー30を被接続鋼板の上に跨るように第1のボルト41を中心として水平面内に90°(図11の矢印方向に)旋回させ、被接続鋼板を上下のフラットバーで挟んで第2のボルト42を通したのち、第1、第2のボルト41、42を締め付けることにより順次鋼板を接続する(図4)。このようにして順次各鋼板を段差なく接続することができる。
【0012】
【発明の効果】
上記のように、本発明はフラットバーとボルトによる固定(接続)方法であるため溶接の手配が不要である。鋼板の接続部位は、通常、僅かな凹凸で段差を生じやすいが、鋼板の接続部位を2枚のフラットバーで挟んでボルト締めすることにより鋼板同士の段差がなくなり、敷き鋼板による仮設路への車両の乗り入れを段差なく安全に保つことができ、また、ボルトを取り外すことで解体も容易で、かつ、再転用も可能である。
