本考案はボルト接続用継手構造を有するコンク
リート杭に関する。[Detailed Description of the Invention] The present invention relates to a concrete pile having a joint structure for bolt connection.
従来のコンクリート杭の継手部は杭同志を溶接
により接続するために杭の両端面に溶接可能な端
板を取りつけていた。しかしながら、杭の接続に
は特殊技術を有する溶接工が必要であり、かつ、
溶接に耐える厚みの端板が必要としていた。その
他、従来のコンクリート杭は端面全面を端板で覆
つていたため、その端板にコストがかかるという
欠点も有していた。 Conventional concrete pile joints have weldable end plates attached to both end faces of the piles in order to connect the piles by welding. However, connecting the piles requires a welder with special skills, and
We needed an end plate thick enough to withstand welding. In addition, conventional concrete piles had the disadvantage that the entire end surface was covered with end plates, which added cost to the end plates.
本考案は、溶接が不要で、接続作業が簡単で、
かつ杭の製造費が安価である継手構造を有するコ
ンクリート杭を提供するものである。 This invention does not require welding, and the connection work is easy.
The present invention also provides a concrete pile having a joint structure that is inexpensive to manufacture.
本考案の杭は第１図、第２図に示すように、杭
１の一方の端面２にアンカーボルトを挿通し得て
ナツトを貫通し得ない小孔５を有し、かつ杭外周

用継手構造を持つコンクリート杭である。 As shown in FIGS. 1 and 2, the pile of the present invention has a small hole 5 in one end surface 2 of the pile 1 through which an anchor bolt can be inserted but cannot pass through a nut. A plurality of box-shaped metal fittings 7 having an opening and anchor reinforcing bars 6 on both sides are buried, and as shown in FIG. This concrete pile has a bolt connection joint structure including a plurality of anchor bolts 3.
このように、本考案の杭は必要なだけの数の箱
状金物７を杭の一端面のみに有し、端面全体に端
板を有しないものであるから、従来の端板を有す

７の上面及び下面の形状を杭の外周に沿つた開口
部となるようにするのが好ましい。また、その箱
状金物７の両側部にアンカー筋６を設け、箱状金
物７とコンクリートとの一体化を高めている。 As described above, the pile of the present invention has the necessary number of box-shaped hardware 7 only on one end face of the pile and does not have end plates on the entire end face, so it is different from conventional piles with end plates. Comparatively, it is cheaper. Also, this box-shaped hardware 7
When embedding during manufacturing of pile 1, box-shaped hardware 7
The box-like hardware 7 can be buried in a predetermined position by passing bolts through the small holes 5 and fixing them at the side ends of the formwork, and pouring concrete into the formwork. In addition, box-shaped hardware 7
In order to prevent concrete from entering the opening of the pile, it is preferable to close the surface facing the opening and to shape the top and bottom surfaces of the box-shaped hardware 7 so that the opening follows the outer periphery of the pile. . In addition, anchor bars 6 are provided on both sides of the box-shaped hardware 7 to enhance the integration of the box-shaped hardware 7 and concrete.
また、本考案の杭の他端は、第３図のように、
箱状金物７の小孔５の位置に対応する位置に、ね
じ切りしたアンカーボルト３がコンクリート端面
８より直接露出している。 In addition, the other end of the pile of the present invention is as shown in Figure 3.
A threaded anchor bolt 3 is directly exposed from the concrete end face 8 at a position corresponding to the position of the small hole 5 of the box-shaped hardware 7.
それ故、本考案の杭同志を接合するに際して
は、箱状金物７の小孔５に、アンカーボルト３を
さしこみ、第４図に示すように、箱状金物７の開
口部よりナツト４を挿入して納め付ければ容易に
杭が接続できる。 Therefore, when joining the piles of the present invention, the anchor bolt 3 is inserted into the small hole 5 of the box-shaped hardware 7, and the nut 4 is inserted through the opening of the box-shaped hardware 7, as shown in FIG. If you put it in place, you can easily connect the stakes.
このように本考案の杭は、箱状金物７を複数個

である上部構造物の重量を支持地盤まで伝える鉛
直力を充分カバーできるのである。更に、杭端面
全面を金具で覆うよりも安価になるというもので
ある。 In this way, the pile of the present invention has a plurality of box-shaped hardware 7 buried therein, anchor bars 6 are provided on both sides of the box-shaped hardware 7, and the points of contact between the anchor bars 6 and the box-shaped hardware 7 are increased. Since the box-like hardware 7 and the concrete are highly integrated, the piles are joined together, and even if the piles become misaligned due to lateral stress on the pile joint, it can be accommodated, and the piles can be The vertical force that transmits the weight of the superstructure to the supporting ground, which is the original function of the structure, can be sufficiently covered. Furthermore, it is cheaper than covering the entire end face of the pile with metal fittings.
なお、接続効果を一層確実ならしめる必要があ

緩み留めに嫌気性有機固化剤を用いたり、埋設金
物の開口部内をセメント等で埋め込む。 In addition, when it is necessary to make the connection effect even more reliable, it is necessary to connect the anchor bolt and nut after applying adhesive to the end face of the pile, use an anaerobic organic solidifying agent to prevent the nuts from loosening, or tighten the openings of the buried hardware. Fill the inside with cement, etc.
なお近年、打撃工法が騒音公害などにより難か
しくなつているが、本考案の杭は打ち込まない杭
の継手構造として有用であり、また長尺の杭が不
適当な住宅地などで用いられる短尺杭、例えば長
さ３ｍ〜５ｍの杭などを本考案の杭とすることに
より簡単に継ぎたしながら杭を埋設できる。 Although the percussion method has become difficult in recent years due to noise pollution, the pile of this invention is useful as a joint structure for piles that are not driven, and is also suitable for short piles used in residential areas where long piles are inappropriate. For example, by using the present invention as a pile with a length of 3 m to 5 m, the pile can be easily connected and buried.
