Description
【０００１】[0001]
本願考案は、開削工法における土留壁、止水壁等に利用される矢板壁、切梁を 支持するための矢板壁用ブラケット、および矢板部材を吊り込むための吊り治具 に関するもので、比較的施工深度の浅い矢板壁を比較的軽量な矢板部材によって 構築する場合に適している。 The present invention relates to a sheet pile wall used as a retaining wall, a water stop wall, etc. in the excavation method, a sheet pile wall bracket for supporting a cutting beam, and a hanging jig for suspending sheet pile members. It is suitable for constructing a sheet pile wall with a shallow construction depth using relatively lightweight sheet pile members.
【０００２】[0002]
例えば、下水管、ガス管、その他の埋設物を開削工事により敷設する場合、あ るいは小口径管推進工法による管の埋設のための立坑の掘削等においては、施工 深度が深い場合、従来の木製の矢板等に代えて鋼矢板が用いられることが多い。 また、比較的軽量な矢板部材として、軽量鋼矢板、アルミニウム合金製の矢板、 あるいはＦＲＰ製の矢板等も用いられている。 For example, when laying sewage pipes, gas pipes, and other buried objects by excavation work, or when excavating vertical shafts for burying pipes by the small-diameter pipe propulsion method, etc. Steel sheet piles are often used instead of wooden sheet piles. Further, as a relatively lightweight sheet pile member, a lightweight steel sheet pile, an aluminum alloy sheet pile, or an FRP sheet pile is used.
【０００３】 特に、ＦＲＰ製の矢板の場合、機械的強度が高いだけでなく、非常に軽量であ ることから、運搬費用の軽減、作業の安全性の面等でも優れており、深度が２〜 数ｍ程度までの施工では、大型の機械を必要とせず、ほとんど人力で作業を行う ことができるといった利点がある。Particularly, in the case of the FRP sheet pile, not only is it high in mechanical strength but also extremely lightweight, it is excellent in terms of transportation cost reduction, work safety, etc. -Construction up to a few meters has the advantage that large machines are not required and the work can be done almost manually.
【０００４】[0004]
比較的深度の浅い施工では、従来、木製の矢板等が使用されてきたが、ＦＲＰ 製の矢板は、上述のような利点があるにもかかわらず、未だ施工実績が少なく、 矢板部材の吊り込みや、腹起し、切梁の取り付け等に関する施工法が確立されて いないため、強度面や耐久性の面での利点が十分に生かされていない。 Conventionally, wooden sheet piles have been used for relatively shallow construction, but despite the advantages described above, FRP sheet piles still have a poor track record of construction, making it possible to suspend sheet pile members. In addition, since the construction method for angling and attachment of cutting beams has not been established, the advantages of strength and durability have not been fully utilized.
【０００５】 このことは、軽量鋼矢板、アルミニウム合金製の矢板等の場合についても同様 である。This is also the case with lightweight steel sheet piles, aluminum alloy sheet piles, and the like.
【０００６】 本願考案は、上述のような比較的施工深度の浅い矢板壁を、ＦＲＰ製、アルミ ニウム合金製の矢板、あるいは軽量鋼矢板等の比較的軽量な矢板部材で構築する 場合について、矢板部材の取り扱いが容易で、施工性に優れ、それによって矢板 部材の持つ特性を十分に生かすことができる矢板壁の構築を可能とすることを目 的としたものである。The present invention is directed to a case where the sheet pile wall having a relatively shallow construction depth as described above is constructed by a sheet pile member made of FRP, an aluminum alloy sheet, or a lightweight steel sheet pile, which is relatively lightweight. The aim is to enable the construction of sheet pile walls that are easy to handle, have excellent workability, and can fully utilize the characteristics of sheet pile members.

【００１６】[0016]
図１および図２は、本願考案の矢板壁およびブラケットの一実施形態を示した ものである。 1 and 2 show an embodiment of a sheet pile wall and a bracket of the present invention.
【００１７】 矢板部材１としては、ＦＲＰ製の矢板部材等の機械的強度に優れ、かつ比較的 軽量であり、比較的施工深度の浅い施工に適したものを用いる。矢板部材１は、 図に示すように、平坦部１ａと山部１ｂを交互に形成した水平断面が波形の矢板 部材であり、山部１ｂが施工における掘削側に突出するようにして矢板壁を形成 する。As the sheet pile member 1, a sheet pile member made of FRP or the like having excellent mechanical strength, being relatively lightweight, and being suitable for construction having a relatively shallow construction depth is used. As shown in the drawing, the sheet pile member 1 is a sheet pile member having a flat horizontal portion 1a and a mountain portion 1b which are alternately formed and has a corrugated horizontal cross section. Form.
【００１８】 図示した例では、一体成形した２枚の矢板部材をボルト７で接続して一枚の矢 板部材１を形成し、図３に示すように上端にアングル８を固着することで、吊り 込み時や地盤への打設時に面外方向の変形が生じ難いようにしてある。In the illustrated example, two sheet pile members integrally formed are connected by bolts 7 to form one sheet pile member 1, and an angle 8 is fixed to the upper end as shown in FIG. It is designed so that deformation in the out-of-plane direction is unlikely to occur at the time of hanging or placing it on the ground.
【００１９】 矢板部材１の山部１ｂの頂部には図３(a) に示されるように間隔をおいて複数 の長孔２が２列（１つの山部１ｂに）穿設されており、設置される腹起し９およ び切梁１０の高さに応じて長孔２を選び、その長孔２に腹起し支持用のブラケッ ト３を取り付けるようになっている。As shown in FIG. 3 (a), a plurality of elongated holes 2 are formed in two rows (in one mountain portion 1b) at intervals at the top of the mountain portion 1b of the sheet pile member 1. The long hole 2 is selected according to the heights of the uprising member 9 and the truss 10 to be installed, and the uprising member 2 is attached with the bracket 3 for supporting the uprising member.
【００２０】 また、本実施形態におけるブラケット３は、筒状のブラケット本体の端部に切 欠きを設け、この切欠き部分に水平断面をＶ字状とした端板４を固定して、矢板 部材１の山部１ｂと嵌合する凹部３ａを形成し、端板４に鉤状の係止部材３ｂを 溶接等で取り付けたものである。In the bracket 3 according to the present embodiment, a notch is provided at an end of a tubular bracket body, and an end plate 4 having a V-shaped horizontal cross section is fixed to the notch so that the sheet pile member. The concave portion 3a is formed so as to fit with the ridge portion 1b of No. 1 and the hook-shaped locking member 3b is attached to the end plate 4 by welding or the like.

Since the mountain portion 1b of the sheet pile member 1 and the recessed portion 3a of the bracket 3 are fitted to each other, stress transmission between the bracket 3 that supports the uprising 9 and the sheet pile member 1 that forms the earth retaining wall is possible. Is smooth and a stable support structure can be obtained.
【００２２】 図４〜図６は、本願考案の吊り治具の一実施形態を示したものである。4 to 6 show an embodiment of the hanging jig of the present invention.
【００２３】 本願考案の吊り治具５は、上述のような矢板部材１について、ブラケット取付 け用の長孔２を吊り込み孔として利用するものであり、ワイヤー等の吊り材１１ を玉掛けするための連結部５ａと、矢板部材１の長孔２に嵌入される係止部５ｂ とからなる。The hanging jig 5 of the present invention uses the long hole 2 for mounting the bracket as a hanging hole in the sheet pile member 1 as described above, for hanging the hanging member 11 such as a wire. And a locking portion 5b fitted in the elongated hole 2 of the sheet pile member 1.
【００２４】 図示した例では、板状の連結部５ａの中央に玉掛け用のシャックル６を取り付 けるための連結孔５ｃが形成されており、この連結部５ａの下端に、連結部５ａ と直交するように、板状、略台形の係止部５ｂが一体に成形されている。In the illustrated example, a connecting hole 5c for mounting a shackle 6 for slinging is formed in the center of the plate-like connecting portion 5a, and the lower end of the connecting portion 5a is orthogonal to the connecting portion 5a. Thus, the plate-shaped, substantially trapezoidal locking portion 5b is integrally molded.
【００２５】 係止部５ｂは、この部分を鉛直に立てることで、長孔２に通すことができ、長 孔２に通した後、９０°回転させることで、図４に示すように係止部５ｂの両側 端のテーパー部分が矢板部材１の山部１ｂの内面に当接する形で係止され、引抜 き力に対して抜け出さないようになっている。The locking portion 5b can be passed through the long hole 2 by standing this portion vertically, and after passing through the long hole 2 and rotated by 90 °, the locking portion 5b is locked as shown in FIG. The tapered portions at both ends of the portion 5b are locked so as to abut against the inner surface of the mountain portion 1b of the sheet pile member 1 so that they do not come out against the pulling force.
【００２６】 この状態で図６に示すようにシャックル６を介して吊り材１１を取り付け、矢 板部材１の吊り込み、引き抜き等に利用することができる。In this state, as shown in FIG. 6, a suspending member 11 can be attached via a shackle 6 and used for suspending, pulling out, and the like of the sheet pile member 1.
【００２７】 吊り治具５の取外しに関しては、少し押し込むことで係止状態を外し、連結部 ５ａを持って９０度回転させることで、容易に長孔２から引き抜くことができる 。With respect to the removal of the hanging jig 5, it can be easily pulled out from the long hole 2 by releasing the locked state by pushing it a little and rotating it by 90 degrees while holding the connecting portion 5a.
【００２８】[0028]
【考案の効果】 本願考案の矢板壁およびブラケットの場合、腹起し支持用のブラケットの取 り付けを、ワンタッチで行うことができ、かつ矢板部材の山部とブラケットの凹 部が嵌合し合う形状であるため、腹起しを支持するブラケットと土留壁を構成す る矢板部材との間の応力伝達がスムーズであり、安定した支持構造が得られる。[Effects of the Invention] In the case of the sheet pile wall and the bracket of the present invention, the mounting of the upright supporting bracket can be performed with one touch, and the mountain portion of the sheet pile member and the concave portion of the bracket are fitted together. Since the shapes are matched with each other, the stress is smoothly transmitted between the bracket that supports the uprising and the sheet pile member that constitutes the retaining wall, and a stable support structure can be obtained.
【００２９】 本願考案の吊り治具は、矢板部材に設けたブラケット取付け用の長孔をその まま吊り込み孔として利用するものであり、取り付け、取り外しがワンタッチで 行なえるだけでなく、取り付け状態において矢板部材の山部内面にしっかり支持 され、吊り込み作業、引き抜き作業を、安全、確実に行うことができる。The hoisting jig of the present invention utilizes the long hole for mounting the bracket provided on the sheet pile member as the hoisting hole as it is. Not only can it be attached and detached with one touch, but also in the attached state. Since it is firmly supported on the inner surface of the mountain part of the sheet pile member, it is possible to safely and surely perform the hanging work and the pulling work.
【００３０】 以上により、比較的施工深度の浅い矢板壁を、ＦＲＰ製、アルミニウム合金 製の矢板、あるいは軽量鋼矢板等の比較的軽量な矢板部材で構築する場合につい て、矢板部材の取り扱いが容易が容易となり、矢板部材の持つ特性を十分に生か すことができる。As described above, it is easy to handle the sheet pile member when constructing the sheet pile wall having a relatively shallow depth of construction with a relatively lightweight sheet pile member such as a sheet made of FRP, an aluminum alloy, or a lightweight steel sheet pile. Therefore, the characteristics of sheet pile members can be fully utilized.
