Even if there is, the steel pile 2 can be driven while avoiding this buried object.
Description
【０００１】[0001]
本考案は、標識や街路灯の支持ポールを市街地の縁石付近に建てる際に有用な 鋼杭基礎に関する。 The present invention relates to a steel pile foundation useful when constructing a support pole for a sign or a street light near a curb in an urban area.
【０００２】[0002]
従来、標識や街路灯の支持ポールを建てるには、地盤を大きく掘り下げ、生コ ンを打込んで支持ポールを固定する方法が採られていたが、この建柱工法では、 工事スペースを広く取り、掘削、型枠組み立て、生コンの打ち込み、養生などの 時間のかかる作業が必要となるため、近年になって図２に示すような打設式の鋼 杭基礎が用いられるようになった。 Conventionally, in order to build a support pole for signs and street lights, a method of digging deep into the ground and driving a raw concrete to fix the support pole was adopted, but this construction pillar method requires a large construction space. Since time-consuming work such as excavation, formwork assembly, driving of raw concrete and curing is required in recent years, the driving type steel pile foundation as shown in Fig. 2 has been used.
【０００３】 図２の鋼杭基礎１１は、Ｈ鋼杭１２の頂端部に定盤１３を溶着し、定盤１３の 上面側の四隅とその内方に固定ボルト１６ａと仮設ボルト１６ｂとを夫々植立状 態に固着して成るもので、この鋼杭基礎１１を地盤１０中に立てる際には、Ｌ字 形の打込みアタッチメント１５の下面に突設した回止め用突起１５ａを定盤１３ 上の穿孔１３ａに係止すると共に、アタッチメント１５に穿設したボルト孔１５ ｂを定盤１３上の仮設ボルト１６ｂに挿通して締結する。そして、この定盤１３ 上に定着したアタッチメント１５を不図示のバイブロハンマーで握持して打設す ることによりＨ鋼杭１２の先端から所定の地盤中に貫入し、定盤１３が地盤面に 達したところで貫入を止めて定盤１３上の各固定ボルト１６ａに支持ポール９の 下端に固着したフランジ９ａの穿孔を通してボルト締結し、次いで定盤１３とフ ランジ９ａとの周辺の掘削孔を結合部を生コン１９で固める。In the steel pile foundation 11 shown in FIG. 2, the surface plate 13 is welded to the top end of the H steel pile 12, and the fixing bolts 16a and the temporary bolts 16b are provided at the four corners on the upper surface side of the surface plate 13 and inside thereof. When the steel pile foundation 11 is erected in the ground 10, a detent 15a protruding from the lower surface of the L-shaped driving attachment 15 is provided on the surface plate 13 when the steel pile foundation 11 is set up in the ground. The bolt hole 15b formed in the attachment 15 is inserted into the temporary bolt 16b on the surface plate 13 and fastened. Then, the attachment 15 fixed on the surface plate 13 is gripped by a vibro hammer (not shown) and driven to penetrate into the predetermined ground from the tip of the H steel pile 12, and the surface plate 13 is ground. At that point, the penetration is stopped and each fixing bolt 16a on the surface plate 13 is bolted through the holes in the flange 9a fixed to the lower end of the support pole 9, and then the drilling holes around the surface plate 13 and the flange 9a are secured. The joint is fixed with fresh concrete 19.
【０００４】 この鋼杭基礎１１によると打設工程が主体となり、地盤１０の掘削は定盤１３ と支持ポール９のフランジ９ａとの結合部周辺ですむから、従来の建柱工法に比 べはるかに掘削土量が少なく、また工事スペースを広く取る必要がなく、型枠組 み立て、生コンの打ち込み、養生などの手間と時間が省略できるものである。According to this steel pile foundation 11, the placing process is mainly performed, and the excavation of the ground 10 is performed only around the joint between the surface plate 13 and the flange 9a of the support pole 9, so that it is far more than the conventional building pillar method. In addition, the amount of excavated soil is small, and there is no need to take a large construction space, and it is possible to save time and labor such as forming a formwork, driving in ready-mixed concrete, and curing.
【０００５】[0005]
ところが、ガス管、水道管、各種ケーブル等の各種の埋設物１６が入り組んだ 市街地において、この鋼杭基礎１１を打設するには、これらの埋設物１６を損傷 或は破壊することがないように避けて打設する必要があるが、縁石１８に近接し た地盤中に埋設物１６があると、その場所での打設工事自体が全くできなくなる という不都合があった。 However, in an urban area where various buried objects 16 such as gas pipes, water pipes, various cables, etc. are complicated, in order to drive this steel pile foundation 11, it is necessary to prevent the buried objects 16 from being damaged or destroyed. It is necessary to avoid it, but if there is an embedded object 16 in the ground near the curbstone 18, there was the inconvenience that the installation work itself could not be performed at that location.
【０００６】 本考案は、このような事情に鑑みてなされたもので、縁石に近接した地盤中に 各種の埋設物があっても標識や街路灯の支持ポールを建柱できるようにした鋼杭 基礎を提供することを目的とする。[0006] The present invention has been made in view of the above circumstances, and is a steel pile capable of forming a support pole for a sign or a street light as a pillar even if there are various buried objects in the ground near the curb. The purpose is to provide the basis.
【０００７】[0007]
本考案の課題を解決するための手段を、実施例に対応する図１に基づいて説明 すると、鋼杭２の頂端部に該鋼杭２の軸線２ａから水平方向にずらして定盤３を 補強板４を介して固着し、前記定盤３の上面側に所要箇所に支持ポール９を連結 するための固定ボルト６ａを立設すると共に、この定盤３の上面側に打込み用ア タッチメント５を締結するための仮設ボルト６ｂを前記鋼杭２の略同軸上に立設 し、前記アタッチメント５はその底部に設けられた突起５ａを前記定盤３の穿孔 ３ａに係止した状態で該定盤３に連結可能としたことを特徴とする。 A means for solving the problems of the present invention will be described with reference to FIG. 1 corresponding to the embodiment. The surface plate 3 is reinforced by horizontally shifting the steel pile 2 from the axis 2a of the steel pile 2 at the top end portion thereof. A fixing bolt 6a for connecting the support pole 9 to a required position is erected on the upper surface side of the surface plate 3 and fixed to the upper surface side of the surface plate 3, and the attachment 5 for driving is mounted on the upper surface side of the surface plate 3. A temporary bolt 6b for fastening the bolt is erected substantially coaxially with the steel pile 2, and the attachment 5 is fixed in a state in which the protrusion 5a provided on the bottom of the attachment 5 is locked in the hole 3a of the surface plate 3. It is characterized in that it can be connected to the board 3.
【０００８】[0008]
上記構成において、定盤３を鋼杭２の軸線２ａから所要間隔だけずらして該鋼 杭２の頂端部に定盤３を補強板４を介して固着したため、定盤３の上面に固定ボ ルト６ａを介して固設される支持ポール９は鋼杭２の打設位置と異なる土壌面に 建柱されるから、支持ポール９の直下に土壌中の埋設物があっても鋼杭２はこの 埋設物を避けて打設することが可能となる。 In the above structure, the platen 3 is displaced from the axis 2a of the steel pile 2 by a required distance, and the platen 3 is fixed to the top end of the steel pile 2 via the reinforcing plate 4. Since the support pole 9 fixed via 6a is built on a soil surface different from the placement position of the steel pile 2, even if there is an embedded object in the soil directly below the support pole 9, It is possible to place the material while avoiding buried objects.
【０００９】 また、鋼杭２を土壌中に埋設するのにバイブロハンマーで打設する場合、バイ ブロハンマーが握持する打込み用アタッチメント５は定盤３上の鋼杭２の略同軸 上に設けられた仮設ボルト６ｂに取り付けられるから、バイブロハンマーは鋼杭 ２の軸心を打設することとなり、定盤３が鋼杭２の軸線からずれた位置にあって も打設効率は良好に保たれる。When the steel pile 2 is driven by a vibro hammer to be buried in the soil, the driving attachment 5 held by the vibro hammer is provided on the surface plate 3 substantially coaxially with the steel pile 2. Since it is attached to the temporary bolt 6b, the vibro hammer drives the shaft center of the steel pile 2 to maintain good driving efficiency even when the surface plate 3 is displaced from the axis of the steel pile 2.

以下、本考案の実施例を図面を参照しながら説明する。 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

A side view and a bottom view of the pile foundation, and Fig. 1 (d) is a side view of the construction state in which the support pole is connected to the steel pile foundation. In these drawings, the same parts as those in FIG. 5 are designated by the same reference numerals.
【００１２】 本実施例の鋼杭基礎１は、図１(a) に示すように、所要長さのＨ鋼からなる鋼 杭２の頂端部において該鋼杭２の軸線２ａからずらした位置に定盤３を溶着する と共に、定盤３と鋼杭２の接合隅部に補強板４を溶着し、定盤３の上面側には、 四隅に固定ボルト６ａを立設し、同じく定盤３の上面側において鋼杭２の略同軸 上に仮設ボルト６ｂを立設してなり、図１(b) に示す打込み用アタッチメント５ はその底部に設けられた回止め用の突起５ａを定盤３の穿孔３ａに係止した状態 でボルト孔５ｂを定盤３の仮設ボルト６ｂに挿通して不図示のナットで締結する 。従って、定盤３の仮設ボルト６ｂに挿通した打込み用アタッチメント５と鋼杭 ２の軸線２ａとは略一致するものである。As shown in FIG. 1 (a), the steel pile foundation 1 of this embodiment is located at a position displaced from the axis 2 a of the steel pile 2 at the top end of the steel pile 2 made of H steel having a required length. While the surface plate 3 is welded, the reinforcing plate 4 is welded to the joint corners of the surface plate 3 and the steel pile 2, and the fixing bolts 6a are erected at the four corners on the upper surface side of the surface plate 3, and the surface plate 3 is also fixed. On the upper surface side of the steel pile 2, a temporary bolt 6b is erected substantially coaxially with the steel pile 2, and the driving attachment 5 shown in FIG. 1 (b) has a protrusion 5a for stopping rotation which is provided on the bottom thereof. The bolt hole 5b is inserted into the temporary bolt 6b of the surface plate 3 while being locked in the hole 3a of FIG. Therefore, the driving attachment 5 inserted into the temporary bolt 6b of the surface plate 3 and the axis 2a of the steel pile 2 are substantially coincident with each other.
【００１３】 このような構成からなる、鋼杭基礎１を沿道の敷石１８付近に打設するには、 図１(d) に示すように、土壌中の埋設管１６を探査した後、この埋設管１６を避 けた位置の土壌表面を掘削し、鋼杭２の定盤３に固設した打込み用アタッチメン ト５を不図示のバイブロハンマーで握持して打込む。このとき、打込み用アタッ チメント５の突起５ａは定盤３の穿孔３ａに係止してあるため、打込み用アタッ チメント５がバイブロハンマーの振動によって離脱することがない。そして、定 盤３が地盤面からやや低い位置まで貫入したところで打込みを停止し、バイブロ ハンマーを取り除いて定盤３上の仮設ボルト６ｂから打込み用アタッチメント５ を離脱し、さらに仮設ボルト６ｂを切断し除去する。次いで、支持ポール９のフ ランジ９ａに穿設されたボルト孔を定盤３上の固定ボルト６ａに通してナットで で締着し、土壌表面の掘削箇所に生コンを打設して支持ポール９の建柱を終える 。In order to drive the steel pile foundation 1 having such a structure near the paving stones 18 along the road, as shown in FIG. 1D, after exploring the buried pipe 16 in the soil, The soil surface at a position away from the pipe 16 is excavated, and the driving attachment 5 fixed to the surface plate 3 of the steel pile 2 is gripped and driven by a vibro hammer not shown. At this time, since the projection 5a of the driving attachment 5 is locked in the hole 3a of the surface plate 3, the driving attachment 5 does not come off due to the vibration of the vibro hammer. Then, when the surface plate 3 penetrates to a position slightly lower than the ground surface, the driving is stopped, the vibro hammer is removed, the driving attachment 5 is detached from the temporary bolt 6b on the surface plate 3, and the temporary bolt 6b is further cut. Remove. Next, the bolt holes formed in the flange 9a of the support pole 9 are passed through the fixing bolts 6a on the surface plate 3 and fastened with nuts, and the ready-mixed concrete is placed at the excavated site on the soil surface to support the pole 9 Finish the building pillar of.
【００１４】 このように、図１(d) に示すような縁石１８或は側溝１７と埋設物１６とが接 近した場所に支持ポール９を建柱する場合、従来の鋼杭基礎であれば、鋼杭２の 直上に支持ポール９を建てようとすると縁石１８に当たって建柱が不可能となる が、本実施例の鋼杭基礎１であれば、鋼杭２を埋設管１６を避けた状態で打設し た後、次いでこの鋼杭２の上に立設する支持ポール９を縁石１８を避けた状態で 連結することができるため、縁石１８と埋設管１６とが相当接近した場所であっ ても鋼杭２の打設及び支持ポール９の建柱が可能となる。しかも、本実施例にお いては、定盤３が鋼杭２の軸心からずれた位置に設けられているが、打込み用ア タッチメント５を締着するための仮設ボルト６ｂは鋼杭２の軸心２ａと略一致し た位置に設けられているから、鋼杭２の打込みが効率よく行われる。As described above, when the support pole 9 is to be constructed at a place where the curb 18 or the gutter 17 and the buried object 16 are close to each other as shown in FIG. However, if the support pole 9 is to be built right above the steel pile 2, the curb 18 hits and the building pillar becomes impossible, but in the case of the steel pile foundation 1 of this embodiment, the steel pile 2 avoids the buried pipe 16. Since the support pole 9 standing upright on the steel pile 2 can be connected to the steel pile 2 while avoiding the curb 18, the curb 18 and the buried pipe 16 are close to each other. However, it is possible to drive the steel piles 2 and to construct the support poles 9. Moreover, in the present embodiment, the surface plate 3 is provided at a position deviated from the axial center of the steel pile 2, but the temporary bolt 6b for fastening the attachment 5 for driving is the steel pile 2. Since it is provided at a position that substantially coincides with the axis 2a of the steel pile 2, the steel pile 2 can be driven efficiently.
【００１５】[0015]
以上説明したように、本考案の鋼杭基礎によれば、鋼杭の軸心からずれた位置 に支持ポールを連結することができるから、複雑に埋設物が入り組んだ市街地の 縁石付近であっても支持ポールが縁石に当たらない位置であれば埋設物を避けて 鋼杭を打設することができ、従来施行不可能であった箇所での標識や街路灯等の 設置が可能となる。 As explained above, according to the steel pile foundation of the present invention, since the support pole can be connected at a position deviated from the axial center of the steel pile, it can be used in the vicinity of the curb in the city where complicated buried objects are complicated. However, if the support pole does not hit the curb, it is possible to drive steel piles while avoiding buried objects, and it is possible to install signs and street lights at locations that were not possible in the past.
【００１６】 しかも、本考案は、打込み用アタッチメントが鋼杭の軸線と略一致した位置に 取り付けられ、バイブロハンマーを用いて効率よく打設することができるから、 掘削土量が少なくてすみ、また工事スペースを広く取る必要がない、また型枠組 み立て、生コンの打ち込み、養生などの手間と時間が省略できる等の上記した従 来の打設式鋼杭基礎の利点はすべて満足することができる。Moreover, according to the present invention, since the driving attachment is mounted at a position substantially aligned with the axis of the steel pile and can be efficiently driven by using the vibro hammer, the amount of excavated soil can be small, and It is not necessary to take a large construction space, and it is possible to satisfy all the advantages of the above-mentioned conventional castable steel pile foundations, such as the time and effort required for forming the frame, driving the ready-mixed concrete, and curing. ..
