Description

本発明は、アングル鉄塔の建設工事において、クライミングクレーンを上部に固定するマストをアングル鉄塔の内側に設け、鉄塔の組み上げ高さに応じて伸長していくマストを建設中のアングル鉄塔と連結して転倒を防止する支線をアングル鉄塔に係止するための支線取付金具に関する。   In the construction work of the angle tower, the mast for fixing the climbing crane to the upper part is provided inside the angle tower, and the mast extending according to the height of the tower is connected to the angle tower under construction. The present invention relates to a branch line mounting bracket for locking a branch line for preventing a fall to an angle steel tower.

従来、鋼管鉄塔の建設方法として、上部にクライミングクレーンを固定したマストを建築中の鉄塔の主柱の内側に設け、鉄塔の組み上げの進行に応じてマストを順次せり上げるものがある（特許文献１）。マストは、鉄塔の主柱と水平にワイヤロープで連結してマストの転倒を防ぐ。このワイヤロープの一端は、マストを取り囲むガイド枠に接続され、他端は主柱に引止ワイヤを巻回し両端の引手に係止したり、主柱にワイヤロープを直接巻き付け係止している。   Conventionally, as a method for constructing a steel pipe tower, there is a method in which a mast with a climbing crane fixed to the upper part is provided inside a main pillar of a steel tower under construction, and the mast is sequentially raised according to the progress of the construction of the steel tower (Patent Document 1 ). The mast is connected to the main pillar of the steel tower horizontally with a wire rope to prevent the mast from falling. One end of this wire rope is connected to a guide frame that surrounds the mast, and the other end is wound around the main column with a retaining wire and locked to the pulls at both ends, or the wire rope is directly wound around and locked to the main column. .

特開平０６−０９３７６１号公報Japanese Patent Application Laid-Open No. 06-093761

上記従来の鋼管鉄塔の組立工法をアングル鉄塔に適用し、主柱を構成するアングル材に引止ワイヤあるいはワイヤロープを巻き付けると、引止ワイヤ等の屈曲部に荷重が集中し、キンクにより強度が低下し、これらの破断を招くおそれがある。引止ワイヤ等がアングル材に直接接触するのを回避するために、主柱にドングロス等の緩衝材を巻いたり、さらに主柱の内側に丸太を添えて緩衝材を巻き付けても、ワイヤロープに大きな張力がかかると、アングル材の角部で応力が集中し局部的に過度の屈曲が生じることでキンクが発生し強度的に不十分である。また、特に傾斜したワイヤロープに張力をかけると、緩衝材が主柱上を滑りワイヤロープに弛みが生ずるおそれがある。アングル材に緩衝材及び重量物の丸太を介してワイヤロープを巻き回す作業は、複数の作業員が関わる大きな労力を必要とし、作業が容易でない。
そこで本発明は、クライミングクレーンを支持するマストをアングル鉄塔の主柱に連結する支線を接続する作業を簡易化して、作業労力を軽減すると共に、支線の接続部分でのキンクによる強度低下や滑りによる弛みを防止するアングル鉄塔用の支線取付金具を提供することを目的とする。 When the conventional steel pipe tower assembly method is applied to an angle tower and a retaining wire or wire rope is wound around the angle material constituting the main column, the load concentrates on the bent portion of the retaining wire and the strength is increased by the kink. There is a risk of lowering and incurring these breaks. In order to prevent the retaining wire etc. from coming into direct contact with the angle material, even if a cushioning material such as a dongle is wrapped around the main pillar, or even if a cushioning material is wrapped around the inside of the main pillar, When a large tension is applied, stress concentrates at the corners of the angle member and excessive bending occurs locally, resulting in kinks and insufficient strength. In particular, when tension is applied to the inclined wire rope, the cushioning material may slide on the main column and the wire rope may become slack. The operation of winding the wire rope around the angle member through the cushioning material and the heavy log requires a large amount of labor involving a plurality of workers and is not easy.
Therefore, the present invention simplifies the work of connecting the branch line connecting the mast supporting the climbing crane to the main column of the angle tower, reduces the work labor, and reduces the strength due to kink at the connecting part of the branch line or due to slippage. An object of the present invention is to provide a branch line mounting bracket for an angle steel tower that prevents loosening.

Both ends of the outer clamp plate 2 are provided with long holes 6 and 7 in the longitudinal direction for allowing the bolts 4 to pass therethrough. One end portion of the outer clamp plate 2 includes an inclined portion 8 that rises outside the bend.

内クランプ板３は、両端部がアングル材Ｔ１の内側面部に沿うように中間部から立ち上がる断面略Ｌ字状をなす。内クランプ板３は、両端部にボルト４を貫通させ外クランプ板２と一体に結合する。内クランプ板３は、図１，図４に示すように、外クランプ板２の一方の長孔６に貫通するボルト４にナット５が螺合することにより外クランプ板２に連結した状態で取り扱われる。内クランプ板３は、長孔６により外クランプ板２に対して、アングル材Ｔ１を受け入れ可能な離間位置と、ボルト４で締め込む接近位置との間で水平方向に相対移動可能である。また内クランプ板３は、傾斜部８により外クランプ板２に対する連結角度を広げることによりアングル材Ｔ１を受け入れる間隔を拡大可能である。内クランプ板３の中間部には、曲がりの内側に向かって突出するように設けられた引手９を備える。引手９は、支線Ｗの先端のシャックルＳを係止する接続孔９ａを備える。   The inner clamp plate 3 has a substantially L-shaped cross section that rises from an intermediate portion so that both end portions are along the inner side surface portion of the angle member T1. The inner clamp plate 3 is coupled integrally with the outer clamp plate 2 by passing bolts 4 through both ends. As shown in FIGS. 1 and 4, the inner clamp plate 3 is handled in a state of being connected to the outer clamp plate 2 by screwing a nut 5 into a bolt 4 penetrating through one long hole 6 of the outer clamp plate 2. It is. The inner clamp plate 3 can be moved relative to the outer clamp plate 2 through the long hole 6 in a horizontal direction between a separated position where the angle member T1 can be received and an approach position where the inner clamp plate 3 is tightened with the bolt 4. Moreover, the space | interval which receives the angle material T1 can be expanded for the inner clamp board 3 by expanding the connection angle with respect to the outer clamp board 2 by the inclination part 8. FIG. The intermediate portion of the inner clamp plate 3 is provided with a handle 9 provided so as to protrude toward the inside of the bend. The pull handle 9 includes a connection hole 9a for locking the shackle S at the tip of the branch line W.

ボルト４は、アングル材Ｔ１の外側において外クランプ板２及び内クランプ板３の両端部を貫通する。ボルト４には、ナット５の内側位置において外クランプ板２と内クランプ板３との間に配置されるスペーサ１０が螺合する。長孔６を貫通するボルト４の軸端部には、ナット５を抜け止めするための割ピン１１が差し込まれる。   The bolt 4 penetrates both end portions of the outer clamp plate 2 and the inner clamp plate 3 outside the angle member T1. A spacer 10 disposed between the outer clamp plate 2 and the inner clamp plate 3 at the inner position of the nut 5 is screwed into the bolt 4. A split pin 11 for preventing the nut 5 from coming off is inserted into a shaft end portion of the bolt 4 penetrating the long hole 6.

外クランプ板２及び内クランプ板３の対向面には、アングル材Ｔ１に当接する部分に弾性合成樹脂製の滑り止めシート１２が貼着されている。   On the opposing surfaces of the outer clamp plate 2 and the inner clamp plate 3, a non-slip sheet 12 made of an elastic synthetic resin is attached to a portion in contact with the angle member T <b> 1.

この支線取付金具１は、アングル鉄塔Ｔの建設工事において、アングル鉄塔ＴとマストＭとを連結する支線Ｗ１を、アングル鉄塔Ｔに係止するためにアングル材Ｔ１に装着される。支線取付金具1は、図４に示すように未使用状態において、予め内クランプ板３の一端部にボルト４を貫通させ、スペーサ１０を介して外クランプ２の長孔６に貫通させてナット５を装着し割ピン１１を差し込んだ状態で、内クランプ板３を外クランプ２に結合しておく。
内クランプ板３は、外クランプ２に対して一端側の長孔６の範囲で相対移動すると共に、外クランプ２の傾斜部８において外クランプ板２との相対角度が拡大するので、他端部において外クランプ２との間隔を拡げることにより、アングル材Ｔ１を容易に受け入れる。
内クランプ板３と外クランプ板２との間にアングル材Ｔ１を配置し、外クランプ板２の他端部にボルト４を貫通させる際、ボルト４が外クランプ板２に対して垂直位置から外れた位置においても長孔7に挿入可能である。
支線取付金具1は、外クランプ板２と内クランプ板３とでアングル材Ｔ１を挟み込み、両ボルト４をナット５で締め込めば、アングル材Ｔ１に確実に固定することができる。取付金具１をアングル材Ｔ１に取り付けたら、引手９にシャックルＳを掛け止めれば支線Ｗ１を係止できる。
なお、外クランプ板２と内クランプ板３との他端部を止めるボルト４やこれに装着するスペーサ１０は、アングル材Ｔ１への装着前に内クランプ板３に一体に組み置けば、分離することがなく取り扱いやすい。 This branch line fitting 1 is attached to the angle member T1 in order to lock the branch line W1 connecting the angle tower T and the mast M to the angle tower T in the construction work of the angle tower T. In the unused state as shown in FIG. 4, the branch line fitting 1 is made to pass through a bolt 4 through one end of the inner clamp plate 3 in advance, and through a long hole 6 of the outer clamp 2 via a spacer 10. And the inner clamp plate 3 is coupled to the outer clamp 2 with the split pin 11 inserted.
The inner clamp plate 3 moves relative to the outer clamp 2 in the range of the long hole 6 on one end side, and the relative angle with the outer clamp plate 2 increases at the inclined portion 8 of the outer clamp 2. The angle member T1 is easily received by widening the gap with the outer clamp 2 in FIG.
When the angle member T1 is disposed between the inner clamp plate 3 and the outer clamp plate 2 and the bolt 4 is passed through the other end portion of the outer clamp plate 2, the bolt 4 comes off the vertical position with respect to the outer clamp plate 2. It can be inserted into the long hole 7 even at a different position.
The branch fitting 1 can be securely fixed to the angle member T1 by sandwiching the angle member T1 between the outer clamp plate 2 and the inner clamp plate 3 and tightening both bolts 4 with the nut 5. When the mounting bracket 1 is attached to the angle member T1, the branch line W1 can be locked if the shackle S is hooked on the handle 9.
In addition, the bolt 4 which stops the other end part of the outer clamp plate 2 and the inner clamp plate 3 and the spacer 10 attached thereto are separated if they are assembled integrally with the inner clamp plate 3 before being attached to the angle member T1. Easy to handle.
