Description

本発明は、構台杭の杭頭構造および構台杭の杭頭に設置される杭頭キャップに関し、打設された複数の構台杭の杭頭高を設定された杭頭高に容易に調整することができ、かつその上に作業構台を効率的に構築できるようにしたものである。 In the present invention, with respect to the pile head structure of the gantry pile and the pile head cap installed on the pile head of the gantry pile, the pile head height of a plurality of gantry piles placed can be easily adjusted to the set pile head height. And it is possible to efficiently build a work gantry on it.

建築・土木工事では、建設機械の作業スペースや建設資材の仮置スペース等を確保のため、本体工事に先行して作業構台が構築される。 In construction and civil engineering work, a work platform is constructed prior to the main construction in order to secure a work space for construction machinery and a temporary storage space for construction materials.

図４は、従来の作業構台の概要を図示したものであり、作業構台30は、地盤に一定間隔に離間して打設された複数の構台杭31,31の上に構築され、各構台杭31の上に立て付けられた構台柱32、構台柱32,32の上端部間に架設された大引33、大引33,33間に架設された根太34および根太34,34間に敷設された覆工板35、さらに各構台柱32,32間に架設された垂直ブレース36等からなり、特に、構台杭31には先端部に螺旋状の羽根を備えた羽根付き鋼管杭が用いられている。 FIG. 4 illustrates an outline of a conventional work gantry. The work gantry 30 is constructed on a plurality of gantry piles 31, 31 placed at regular intervals on the ground, and each gantry pile is constructed. The gantry pillar 32 erected on 31 and the large pull 33 erected between the upper ends of the gantry pillars 32 and 32, and the joists 34 and the joists 34, 34 erected between the large pulls 33 and 33. It consists of a lining plate 35 and vertical braces 36 erected between the gantry pillars 32 and 32. In particular, the gantry pile 31 uses bladed steel pipe piles with spiral blades at the tip. There is.

羽根付き鋼管杭は、鋼管の先端部に地盤への回転貫入を容易にする翼を備え、特に低振動、低騒音、無排土施工が可能で環境への負荷が少ない。 The bladed steel pipe pile is equipped with wings at the tip of the steel pipe that facilitates rotational penetration into the ground, and is capable of low vibration, low noise, and soil-free construction, and has a low impact on the environment.

また、大きな支持力を持ちながら撤去が容易で、かつ再使用が可能で経済性に優れているため、作業構台などの後々撤去される仮設構造物の基礎杭として用いられる。 In addition, it is used as a foundation pile for temporary structures that will be removed later, such as work gantry, because it has a large bearing capacity, is easy to remove, can be reused, and is economical.

しかし、羽根付き鋼管杭は、施工に際して杭頭レベルの管理が非常に難しく、施工される杭の全てについて杭頭高を一致させることは非常に困難であった。 However, it is very difficult to control the pile head level of the steel pipe pile with blades at the time of construction, and it is very difficult to match the pile head height for all the piles to be constructed.

このため、従来、打設された各構台杭の上に構台柱を立設して作業構台を構築する際は、各構台杭ごとに構台柱の長さを決め、また、構台柱に接合される大引や垂直ブレース等をボルト締結するためのボルト孔は、機械式穴明け機を用い現地で穴明けを行う必要があった。このため、施工効率が非常に悪く、工期の長期化等が避けられない等の課題があった。 For this reason, conventionally, when a gantry pillar is erected on each gantry pile that has been cast to construct a work gantry, the length of the gantry pillar is determined for each gantry pile and is joined to the gantry pillar. Bolt holes for bolting large pulls and vertical braces had to be drilled locally using a mechanical drilling machine. For this reason, there are problems such as very poor construction efficiency and inevitable prolongation of the construction period.

本発明は、以上の課題を解決するためになされたもので、打設された複数の構台杭の杭頭高を設定された杭頭高に容易に調整することができ、かつその上に作業構台を効率的に構築できるようにした構台杭の杭頭構造および杭頭キャップを提供することを目的とするものである。 The present invention has been made to solve the above problems, and the pile head heights of a plurality of gantry piles placed can be easily adjusted to the set pile head heights, and the work is performed on the pile head heights. It is an object of the present invention to provide a pile head structure and a pile head cap of a gantry pile that enables efficient construction of a gantry.

本発明は、地盤中に打設された羽根付き鋼管杭からなる複数の構台杭と、前記構台杭のそれぞれの杭頭に立設された複数の構台柱と、前記構台柱間に架設された複数の大引および複数の垂直ブレースと前記大引間に架設された複数の根太および前記根太の上に敷設された複数の覆工板とを備えてなる作業構台において施工される構台杭の杭頭構造の発明であり、前記構台杭の杭頭に、前記構台杭間の杭頭高を同一高に調整する杭頭キャップが設置され、前記杭頭キャップは、前記構台杭の設定された杭頭高(設計杭頭高)に対して不足する高さを補足する高さに形成され、かつ前記構台杭の杭頭に固定されたキャップ本体と、前記キャップ本体の上端部に設けられ、前記構台柱が固定されたベース部と、前記キャップ本体と前記ベース部との隅角部に設けられ、前記キャップ本体および前記ベース部を補強する複数の補強リブを備えていることを特徴とするものである。 The present invention is erected between a plurality of gantry piles made of steel pipe piles with blades placed in the ground, a plurality of gantry pillars erected at the pile heads of the gantry piles, and the gantry pillars. Pile of gantry piles constructed in a work gantry including a plurality of large pulls and a plurality of vertical braces, a plurality of roots erected between the large pulls, and a plurality of lining plates laid on the roots. It is an invention of the head structure, and a pile head cap for adjusting the pile head height between the gantry piles is installed on the pile head of the gantry pile, and the pile head cap is a pile on which the gantry pile is set. The cap body is formed at a height that supplements the height that is insufficient with respect to the head height (design pile head height) and is fixed to the pile head of the gantry pile, and is provided at the upper end of the cap body. It is characterized in that it is provided at a base portion to which a gantry pillar is fixed and a corner portion between the cap body and the base portion, and is provided with a plurality of reinforcing ribs for reinforcing the cap body and the base portion. Is.

前記構台杭には、特に先端部に螺旋状の羽根を備えた羽根付き鋼管杭が用いられていることで、低振動、低騒音、無排土施工が可能となり、環境への負荷を少なくすることができる。 Since a steel pipe pile with blades having spiral blades at the tip is used for the gantry pile, low vibration, low noise, and soil-free construction are possible, and the burden on the environment is reduced. be able to.

また、羽根付き鋼管杭は、大きな支持力を持ちながら撤去が容易で、後々撤去される作業構台の基礎杭には適している。 Further, the bladed steel pipe pile has a large bearing capacity and is easy to remove, and is suitable for a foundation pile of a work platform to be removed later.

通常は、各構台杭のそれぞれの杭頭に、設定された杭頭高(設計杭頭高)に対して不足する杭頭高を補足する高さに調整された杭頭キャップを設置し、その上に作業構台の構台柱を直接立て付けるが、作業構台の設置地盤が不安定であったり、或いは作業構台の床面積が広く作業構台の規模が大きいとき等には、前記杭頭キャップを設置した杭頭間に敷桁を架設し、その上に作業構台の構台柱を立て付けることにより、杭頭部を補強して作業構台の安定性を高めることができる。 Normally, a pile head cap adjusted to a height that supplements the pile head height that is insufficient for the set pile head height (design pile head height) is installed on each pile head of each gantry pile. The gantry pillar of the work gantry is erected directly on the top, but when the installation ground of the work gantry is unstable, or when the floor area of the work gantry is large and the scale of the work gantry is large, the pile head cap is installed. By erection of a laying girder between the pile heads and erection of the gantry pillar of the work gantry on it, the pile head can be reinforced and the stability of the work gantry can be improved.

その際、一部の杭頭キャップを省略し、その代替部材として杭頭と敷桁との間にプレート等を複数層に重ねて介在することにより、杭頭キャップの種類を減らすこともできる。 At that time, the number of types of pile head caps can be reduced by omitting a part of the pile head caps and interposing a plate or the like in a plurality of layers between the pile heads and the floor girders as an alternative member.

杭頭キャップは、鋼管と複数のプレートを用いて溶接により形成することができ、また、鋳造によって一体的に形成することもできる。 The pile head cap can be formed by welding using a steel pipe and a plurality of plates, or can be integrally formed by casting.

本発明は、打設された複数の構台杭の杭頭に杭頭キャップを設置することにより、構台杭間の杭頭高を同じ高さに容易に調整することができ、これにより各構台杭の杭頭に構台柱を立て付けて作業構台をきわめて効率的に構築することができる。 According to the present invention, by installing pile head caps on the pile heads of a plurality of gantry piles that have been cast, the height of the pile heads between the gantry piles can be easily adjusted to the same height, whereby each gantry pile can be easily adjusted. It is possible to construct a work gantry extremely efficiently by erecting a gantry pillar on the pile head of the pile.

特に、構台柱と大引間や垂直ブレース間などの各部材間の接合は、原則、接合ボルト(図省略)によってなされるため、杭頭キャップによって構台杭の杭頭高を全て同じ杭頭高に調整することにより、構台柱や垂直ブレース等のカットや穴あけ加工は、全て工場にて正確かつ容易に行うことができ、また、これにより、現地における作業構台の構築もきわめて効率的に行うことができる。 In particular, since the joint between the gantry pillar and each member such as between the large pulling and the vertical brace is made by the joining bolt (not shown) in principle, the pile head cap makes the pile head height of the gantry pile the same. By adjusting to, all cutting and drilling of gantry pillars and vertical braces can be performed accurately and easily at the factory, and by doing so, the construction of the work gantry on site can be performed extremely efficiently. Can be done.

図１と図２は、本発明の一実施形態を図示したものであり、地盤中に打設された複数の構台杭、複数の構台杭の上に構築された作業構台および複数の構台杭のそれぞれの杭頭に設置された杭頭キャップを図示したものである。 1 and 2 show an embodiment of the present invention, in which a plurality of gantry piles placed in the ground, a work gantry built on a plurality of gantry piles, and a plurality of gantry piles are shown. The pile head caps installed on each pile head are illustrated.

図において、一定区画の敷地内の地盤中に複数の構台杭１が作業構台２の桁行方向および梁間方向に所定間隔に離間して打設され、当該各構台杭１のそれぞれの杭頭に杭頭キャップ３が設置されている。 In the figure, a plurality of gantry piles 1 are placed in the ground in a certain section of the site at predetermined intervals in the girder direction and the beam-to-beam direction of the work gantry 2, and piles are placed at the respective pile heads of the gantry piles 1. The head cap 3 is installed.

構台杭１には、特に先端部に螺旋状の羽根を備えた羽根付き鋼管杭が用いられている。羽根付き鋼管杭は、鋼管の先端部に地盤への回転貫入を容易にする翼を備えていることで、特に低振動、低騒音、無排土施工が可能で環境への負荷が少ない。 As the gantry pile 1, a steel pipe pile with blades having a spiral blade at the tip thereof is particularly used. The bladed steel pipe pile is equipped with a blade at the tip of the steel pipe that facilitates rotational penetration into the ground, which enables low vibration, low noise, and no soil removal, and has a low impact on the environment.

また、大きな支持力を持ちながら撤去が容易で、しかも繰り返しの使用が可能で経済性にも優れているため、作業構台などの後々撤去される仮設構造物の基礎杭などに適している。 In addition, it has a large bearing capacity, is easy to remove, can be used repeatedly, and is economical, so it is suitable for foundation piles of temporary structures that will be removed later, such as work gantry.

杭頭キャップ３は、地盤中に打設された各構台杭１の杭頭高を、設定された杭頭高(設計杭頭高)に調整するための高さ調整部材であり、構台杭１の上端部に取り付けられたキャップ本体3aと、キャップ本体3aの上端部に取り付けられたベースプレート3bと、キャップ本体3aとベースプレート3bとの隅角部(入隅部)に取り付けられた複数の補強リブ3cとを備えている。 The pile head cap 3 is a height adjusting member for adjusting the pile head height of each gantry pile 1 placed in the ground to the set pile head height (design pile head height), and is a gantry pile 1 A plurality of reinforcing ribs attached to the corners (inner corners) of the cap body 3a attached to the upper end of the cap body 3a, the base plate 3b attached to the upper end of the cap body 3a, and the cap body 3a and the base plate 3b. It has 3c.

キャップ本体3aは、構台杭１とほぼ同径の鋼管から形成され、特にその高さｈは、各構台杭１の杭頭高ｈ1ごとに設計杭頭高ｈ2に対して不足する高さを補足する高さｈに設定されている。 The cap body 3a is formed of a steel pipe having almost the same diameter as the gantry pile 1, and in particular, its height h is insufficient for each pile head height h 1 of each gantry pile 1 with respect to the design pile head height h 2 . Is set to a height h that supplements.

例えば、構台杭１の杭頭高がｈ1で設計杭頭高ｈ2より低いときは、キャップ本体3aはｈ2−ｈ1の高さｈに形成されている。したがって、キャップ本体3aは、設置される各構台杭１ごとに高さｈが異なっている。 For example, when the pile head height of the gantry pile 1 is h 1 and is lower than the design pile head height h 2 , the cap body 3a is formed at a height h of h 2 −h 1 . Therefore, the height h of the cap main body 3a is different for each gantry pile 1 to be installed.

このように形成されたキャップ本体3aは、各構台杭１の上端部に溶接によって一体的に取り付けられ、これにより各構台杭１の杭頭高は、すべて設計杭頭高ｈ2に統一されている。 The cap body 3a formed in this way is integrally attached to the upper end of each gantry pile 1 by welding, whereby the pile head height of each gantry pile 1 is unified to the design pile head height h 2. There is.

ベースプレート3bは、キャップ本体3aの外径より大きい寸法の板状に形成され、キャップ本体3aの上端部に一体的に溶接されている。また、ベースプレート3bの所定位置に後述する敷桁４をボルト締結するためのボルト孔3dが複数形成されている。 The base plate 3b is formed in a plate shape having a size larger than the outer diameter of the cap body 3a, and is integrally welded to the upper end portion of the cap body 3a. Further, a plurality of bolt holes 3d for bolting the floor girder 4, which will be described later, are formed at predetermined positions of the base plate 3b.

なお、ベースプレート3bの平面形状は、特に限定されるものではなく、図示するような矩形板状でも円形板状であってもよい。また、補強リブ3cは、キャップ本体3aの円周方向に等間隔に配置され、キャップ本体3aおよびベースプレート3bに一体的に溶接されている。 The planar shape of the base plate 3b is not particularly limited, and may be a rectangular plate or a circular plate as shown in the figure. Further, the reinforcing ribs 3c are arranged at equal intervals in the circumferential direction of the cap body 3a and are integrally welded to the cap body 3a and the base plate 3b.

また、キャップ本体3a、ベースプレート3bおよび補強リブ3cは、工場において杭頭キャップ３として溶接により一体的に製作されており、特に、キャップ本体3aは、全ての構台杭１に対応できるように長めに形成し、現地にて設置される構台杭１の杭頭高ｈ1に合わせてカットするようにしてもよい。 Further, the cap body 3a, the base plate 3b and the reinforcing rib 3c are integrally manufactured by welding as the pile head cap 3 at the factory. In particular, the cap body 3a is made longer so that it can correspond to all the gantry piles 1. It may be formed and cut according to the pile head height h 1 of the gantry pile 1 installed in the field.

また、キャップ本体3a、ベースプレート3bおよび補強リブ3cは、鋳造により杭頭キャップ３として一体的に形成することもできる。 Further, the cap body 3a, the base plate 3b and the reinforcing rib 3c can be integrally formed as the pile head cap 3 by casting.

作業構台２の桁行方向および梁間方向の各構台杭１,１の上端部間に敷桁４が架設されている。敷桁４には主としてＨ形鋼が用いられ、各構台杭１の上端部に設置された杭頭キャップ３のベースプレート3bの上に載置され、かつボルト孔3dを貫通する複数の締結ボルト５によって脱着可能に固定されている。 A laying girder 4 is erected between the upper ends of the gantry piles 1 and 1 in the girder row direction and the beam-to-beam direction of the work gantry 2. H-shaped steel is mainly used for the paving girder 4, and a plurality of fastening bolts 5 which are placed on the base plate 3b of the pile head cap 3 installed at the upper end of each gantry pile 1 and penetrate the bolt holes 3d.

さらに、各敷桁４の上に作業構台２の構台柱６が桁行方向および梁間方向に所定間隔に離間して立て付けられている。構台柱６には主としてＨ形鋼が用いられ、また、構台柱６は構台杭１の直上に立て付けられ、かつ敷桁４の上に複数の固定ボルト７によってボルト締結することで脱着可能に固定されている。 Further, the gantry pillars 6 of the work gantry 2 are erected on each laying girder 4 at predetermined intervals in the girder row direction and the beam-to-beam direction. H-shaped steel is mainly used for the gantry pillar 6, and the gantry pillar 6 is erected directly above the gantry pile 1 and can be attached and detached by bolting on the floor girder 4 with a plurality of fixing bolts 7. It is fixed.
