Description

本発明は、受圧板を吊り下げるための吊下げ治具に関し、特に、受圧板を傾斜させた状態で保つ機能を備えた吊下げ治具に関する。 The present invention relates to a hanging jig for suspending a pressure receiving plate , and more particularly to a hanging jig having a function of keeping the pressure receiving plate in an inclined state.

一般に、グラウンドアンカー用として使用される受圧板３１は、図１０及び図１１に示すように、略円錐台形状をなすものであって、地山５０の斜面５１上に、斜面５１の傾斜角度、向きに合わせて設置され、この受圧板３１を介して地山５０に打設されるテンドン（図示せず）の緊張力が地山５０側に伝達され、地山５０に地すべり等が生じるのが防止される。 In general, the pressure receiving plate 31 used for the ground anchor has a substantially truncated cone shape as shown in FIGS. 10 and 11, and the inclination angle of the inclined surface 51 on the inclined surface 51 of the natural ground 50, The tension force of a tendon (not shown) that is installed according to the direction and is placed on the natural ground 50 through the pressure receiving plate 31 is transmitted to the natural ground 50 side, and a landslide or the like occurs in the natural ground 50. Is prevented.

上記のような構成の受圧板３１を地山５０の斜面５１上に設置するには、図１０及び図１１に示すように、２台のクレーン（又はチェーンブロック）を用い、受圧板３１の周面の４箇所にそれぞれアイボルト３８を介してワイヤー３７の一端部を取り付ける。 In order to install the pressure receiving plate 31 configured as described above on the slope 51 of the natural ground 50, as shown in FIGS. 10 and 11, two cranes (or chain blocks) are used to surround the pressure receiving plate 31. One end of a wire 37 is attached to each of four locations on the surface via eyebolts 38.

そして、斜面５１の上位側となる受圧板３１の部分に取り付けた２本のワイヤー３７、３７の他端部を一方のクレーン（又はチェーンブロック）のフック３６に取り付け、斜面５１の下位側となる受圧板３１の部分に取り付けた２本のワイヤー３７、３７の他端部を他方のクレーン（又はチェーンブロック）のフック３５に取り付ける。 Then, the other ends of the two wires 37, 37 attached to the portion of the pressure receiving plate 31 on the upper side of the slope 51 are attached to the hook 36 of one crane (or chain block), and become the lower side of the slope 51. The other ends of the two wires 37 attached to the pressure receiving plate 31 are attached to the hook 35 of the other crane (or chain block).

そして、一方のクレーン及び他方のクレーンを操作し、一方のクレーンのフック３５の上下方向の位置及び他方のクレーンのフック３６の上下方向の位置を調整することにより、受圧板３１の傾斜角度を地山５０の斜面５１の傾斜角度に合わせる。そして、受圧板３１を矢印の方向に押すことにより、受圧板３１の水平方向の向きを地山５０の斜面５１の向きに合わせる。そして、このような傾斜角度の調整作業、向きの調整作業を行うことにより、受圧板３１が地山５０の所定の位置の斜面５１上に設置される。 Then, by operating one crane and the other crane and adjusting the vertical position of the hook 35 of one crane and the vertical position of the hook 36 of the other crane, the inclination angle of the pressure receiving plate 31 can be adjusted to the ground. Adjust to the slope angle of slope 51 of mountain 50. Then, by pressing the pressure receiving plate 31 in the direction of the arrow, the horizontal direction of the pressure receiving plate 31 is matched with the direction of the slope 51 of the natural ground 50. And the pressure receiving plate 31 is installed on the slope 51 of the predetermined position of the natural ground 50 by performing adjustment work of such an inclination angle, and adjustment work of direction.

そして、受圧板３１を地山５０の斜面５１上に設置した後に、地山５０に打設したテンドン（図示せず）の上端部を受圧板３１の中心部の貫通孔３２内を挿通させ、ジャッキ（図示せず）によりテンドンを緊張させ、テンドンの上端部に定着具（図示せず）を装着し、テンドンを緊張させた状態に保持することにより、テンドンの緊張力を地山５０側に伝達させることができる。 And after installing the pressure receiving plate 31 on the slope 51 of the natural ground 50, the upper end part of the tendon (not shown) cast in the natural ground 50 is inserted in the through-hole 32 of the center part of the pressure receiving plate 31, The tendon is tensioned by a jack (not shown), a fixing tool (not shown) is attached to the upper end of the tendon, and the tendon is held in a tense state, so that the tendon tension is applied to the natural ground 50 side. Can be transmitted.

ところで、上記のように２台のクレーン（又はチェーンブロック）を使用して受圧板３１を地山５０の斜面５１上に設置する場合に、２台のクレーン（又はチェーンブロック）を操作して、一方のクレーンのフック３５及び他方のクレーンのフック３６の上下方向の位置を調整して受圧板３１の角度を調整しなければならないため、その作業に多大な労力と時間を有し、作業効率が低下し、工期が長くなってしまう。 By the way, when installing the pressure receiving plate 31 on the slope 51 of the natural ground 50 using two cranes (or chain blocks) as described above, the two cranes (or chain blocks) are operated, Since the angle of the pressure receiving plate 31 must be adjusted by adjusting the vertical position of the hook 35 of one crane and the hook 36 of the other crane, the work has a lot of labor and time, and the work efficiency is high. It will decrease and the construction period will be longer.

また、クレーンを操作する作業者の熟練度によって受圧板３１の傾斜角度の調整にばらつきが生じるため、常に一定の精度で受圧板３１を斜面５１上に設置することができない。このため、図１２に示すように、受圧板３１と斜面５１との間に不陸調整用マット５２を使用する場合には、受圧板３１の傾斜角度、向きを調整する作業中に、不陸調整用マット５２に傷を付けたり、損傷させたりする虞があるため、受圧板３１の傾斜角度の調整に多大な労力と時間がかかり、作業効率が低下し、工期が長くなってしまう。 Further, since the adjustment of the inclination angle of the pressure receiving plate 31 varies depending on the skill level of the operator who operates the crane, the pressure receiving plate 31 cannot always be installed on the slope 51 with a certain accuracy. For this reason, as shown in FIG. 12, when the unevenness adjustment mat 52 is used between the pressure receiving plate 31 and the inclined surface 51, the unevenness during the operation of adjusting the inclination angle and direction of the pressure receiving plate 31 is not performed. Since there is a risk of scratching or damaging the adjustment mat 52, adjustment of the inclination angle of the pressure receiving plate 31 takes a great deal of labor and time, resulting in a decrease in work efficiency and a longer work period.

本発明は、上記のような従来の問題に鑑みなされたものであって、受圧板を地山の斜面上に設置する場合、受圧板の傾斜角度及び向きを設置箇所の斜面の傾斜角度及び向きに容易にかつ高精度で合わせることができ、これにより、受圧板を斜面へ設置する際に要する労力、時間を大幅に削減することができ、作業効率を高め、工期を短縮することができる吊下げ治具を提供することを目的とするものである。 The present invention has been made in view of the conventional problems as described above, when installing the pressure receiving plate on the slope of the natural ground, the inclination angle and orientation of the tilt angle and orientation of installation locations slope of the pressure receiving plate Can be adjusted easily and with high accuracy. This makes it possible to significantly reduce the labor and time required to install the pressure receiving plate on the slope, to improve work efficiency and shorten the construction period.

A ground anchor tendon (not shown) is inserted through the inside 12. A plurality of screw holes (not shown) are provided at predetermined intervals in the circumferential direction in the peripheral portion of the through hole 12 on the upper surface side of the pressure receiving plate 11. The hanging jig 1 is attached to the upper portion of the pressure receiving plate 11 by screwing screws (not shown) inserted into the respective screw insertion holes 4 of the attachment portion 2.

そして、上記のように構成したこの実施の形態による吊下げ治具１を用いて被吊下げ体１０である受圧板１１を地山２０の斜面２１上に設置するには、まず、取付け部２を受圧板１１の上部に位置して、取付け板３のねじ挿通用の孔４を受圧板１１のねじ孔に一致させ、取付け板３の各ねじ挿通用の孔４内にねじ（図示せず）を挿通させ、各ねじを受圧板１１側のねじ孔に螺合させて締め付け、取付け部２を介して吊下げ治具１を受圧板１１に取り付ける。この場合、図５に示すように、吊下げ治具１を受圧板１１に固定する前に、吊下げ治具１を受圧板１１上で回転させて、受圧板１１を地山２０の斜面２１上に設置したときに上位となる受圧板１１の部分に吊下げ治具１の吊下げ部６を位置させ、受圧板１１の円周方向に対する吊下げ治具１の相対的な位置決めをする。 In order to install the pressure receiving plate 11 as the suspended body 10 on the slope 21 of the natural ground 20 using the hanging jig 1 according to this embodiment configured as described above, first, the mounting portion 2 Is positioned above the pressure receiving plate 11, the screw insertion hole 4 of the mounting plate 3 is matched with the screw hole of the pressure receiving plate 11, and a screw (not shown) is inserted into each screw insertion hole 4 of the mounting plate 3. ) Are inserted, each screw is screwed into a screw hole on the pressure receiving plate 11 side and tightened, and the hanging jig 1 is attached to the pressure receiving plate 11 via the attachment portion 2. In this case, as shown in FIG. 5, before fixing the hanging jig 1 to the pressure receiving plate 11, the hanging jig 1 is rotated on the pressure receiving plate 11, so that the pressure receiving plate 11 is inclined to the slope 21 of the natural ground 20. The hanging portion 6 of the hanging jig 1 is positioned at the upper pressure receiving plate 11 when installed on the upper side, and the hanging jig 1 is positioned relative to the circumferential direction of the pressure receiving plate 11.

そして、図３及び図４に示すように、吊下げ治具１の吊下げ部６の各アーム板７の所定の吊下げ孔８ａ〜８ｌ内にアイボルト等を介してワイヤー１７の一端部を掛着させ、ワイヤー１７の他端部をクレーン１５のフックに掛着させる。この場合、図示はしないが、１本のワイヤーを両アーム板７、７の所定の吊下げ孔８ａ〜８ｌ間に掛着させても良い。 As shown in FIGS. 3 and 4, one end of the wire 17 is hooked into the predetermined suspension holes 8 a to 8 l of the arm plates 7 of the suspension part 6 of the suspension jig 1 via eyebolts or the like. The other end of the wire 17 is hooked on the hook of the crane 15. In this case, although not shown, one wire may be hooked between predetermined suspension holes 8a to 8l of both arm plates 7 and 7.

そして、クレーンを操作することにより、２本のワイヤー１７、１７及び吊下げ治具１を介して受圧板１１を上昇させ、受圧板１１を地山２０の所定の位置に搬送し、地山２０の斜面２１上に設置する。 Then, by operating the crane, the pressure receiving plate 11 is raised via the two wires 17 and 17 and the hanging jig 1, and the pressure receiving plate 11 is conveyed to a predetermined position of the natural ground 20. It is installed on the slope 21.

この場合、受圧板１１は、ワイヤー１７、１７を掛着させる吊下げ孔８ａ〜８ｌの位置に応じた角度に傾斜し、その傾斜角度を保った状態で地山２０の所定の位置に搬送されるので、地山２０の斜面２１の傾斜角度に対応する吊下げ孔８ａ〜８ｌを用いることにより、斜面２１への設置の際に、図３に矢印で示すように、受圧板１１の水平方向の向きのみを調整すれば良いことになる。 In this case, the pressure receiving plate 11 is inclined at an angle corresponding to the position of the suspension holes 8a to 8l to which the wires 17 and 17 are hooked, and is conveyed to a predetermined position of the natural ground 20 while maintaining the inclination angle. Therefore, by using the suspension holes 8 a to 8 l corresponding to the inclination angle of the slope 21 of the natural ground 20, the horizontal direction of the pressure receiving plate 11 is shown in FIG. It is only necessary to adjust the direction of the.

すなわち、アーム板７に設ける複数の吊下げ孔８ａ〜８ｌを、各種の傾斜角度の斜面に対応するように予め設定しておくことにより、設置箇所において、受圧板１１の傾斜角度を調整する必要はなく、受圧板１１の向きを斜面の向きに合わせる作業だけですむことになる。 That is, it is necessary to adjust the inclination angle of the pressure receiving plate 11 at the installation location by setting in advance the plurality of suspension holes 8a to 8l provided in the arm plate 7 so as to correspond to the inclined surfaces having various inclination angles. Rather, it is only necessary to adjust the direction of the pressure receiving plate 11 to the direction of the slope.

この実施の形態においては、第１吊下げ孔８ａ〜第１２吊下げ孔８ｌ（第１吊下げ孔８ａ、第３吊下げ孔８ｃ、第４吊下げ孔８ｄ、第１２吊下げ孔８ｌのみ表示。）に対応する受圧板１１の傾斜角度を図６〜図９に示すように設定している。 In this embodiment, only the first to 12th suspension holes 8a to 8l (the first suspension hole 8a, the third suspension hole 8c, the fourth suspension hole 8d, and the 12th suspension hole 8l are displayed.

The pressure receiving plate 11 is inclined at a predetermined angle (the angle formed by the wire 17 and the bottom surface of the pressure receiving plate 11 is 58 °).

（４）第１２吊下げ孔
図９に示すように、第１２吊下げ孔８ｌにワイヤー１７を掛着させた場合には、第１２吊下げ孔８ｌが受圧板１１の重心を通る線から所定の距離離れていることにより、受圧板１１は所定の角度（ワイヤー１７と受圧板１１の底面とのなす角度が２１°）に傾斜する。 (4) 12th hanging hole As shown in FIG. 9, when the wire 17 is hooked on the 12th hanging hole 81, the 12th hanging hole 8l is predetermined from the line passing through the center of gravity of the pressure receiving plate 11. The pressure receiving plate 11 is inclined at a predetermined angle (the angle formed by the wire 17 and the bottom surface of the pressure receiving plate 11 is 21 °).

上記のように構成したこの実施の形態による吊下げ治具１にあっては、受圧板１１をワイヤー１７を介して吊下げることにより、受圧板１１を所定の角度に傾斜させ、その傾斜角度に保つことができるので、地山２０の斜面２１上に設置する場合に、受圧板１１の向きを斜面２１の向きに合わせる作業だけで済むことになる。 In the hanging jig 1 according to this embodiment configured as described above, the pressure receiving plate 11 is inclined at a predetermined angle by suspending the pressure receiving plate 11 via the wire 17, and the inclination angle is set to the inclination angle. Therefore, when installing on the slope 21 of the natural ground 20, it is only necessary to adjust the direction of the pressure receiving plate 11 to the direction of the slope 21.

従って、受圧板１１の地山２０の斜面２１上への設置作業が容易となり、設置に要する手間、時間を大幅に削減することができる。 Therefore, the installation work of the pressure receiving plate 11 on the slope 21 of the natural ground 20 is facilitated, and labor and time required for the installation can be greatly reduced.

また、受圧板１１の傾斜角度を設定する場合に、１台のクレーンの操作によって受圧板１１を所定の傾斜角度に容易に設定することができるので、受圧板１１を所定の傾斜角度に設定する作業の効率を高めることができる。 Moreover, when setting the inclination angle of the pressure receiving plate 11, since the pressure receiving plate 11 can be easily set to a predetermined inclination angle by operation of one crane, the pressure receiving plate 11 is set to a predetermined inclination angle. The work efficiency can be increased.

さらに、使用する吊下げ孔８ａ〜８ｌの位置に応じた角度に受圧板１１の傾斜角度が設定されることになるので、設置精度を大幅に高めることができ、不陸調整用マットを地山２０と受圧板１１との間に介装させる場合にも、不陸調整用マットを傷つけたり、損傷させたりする虞はない。 Furthermore, since the inclination angle of the pressure receiving plate 11 is set to an angle corresponding to the position of the suspension holes 8a to 8l to be used, the installation accuracy can be greatly increased, and the unevenness adjustment mat can be used as a natural ground. Even when it is interposed between the pressure plate 20 and the pressure receiving plate 11, there is no possibility of damaging or damaging the unevenness adjusting mat.

さらに、使用する吊下げ孔８ａ〜８ｌの位置に応じた角度に受圧板１１の傾斜角度が設定されることになるので、１つの吊下げ治具１で各種の傾斜角度の斜面に対応することができ、汎用性を高めることができる。 Furthermore, since the inclination angle of the pressure receiving plate 11 is set to an angle corresponding to the position of the suspension holes 8a to 8l to be used, the single suspension jig 1 can cope with slopes having various inclination angles. And versatility can be improved.
