(Configuration of driving tool 100)
The driving tool 100 mainly includes a driving jig 200 and a driving guide 300. The driving jig 200 is an instrument that is applied to the construction bar portion 92 of the U-shaped fastener 90 and transmits the impact force when the U-shaped fastener 90 is driven. As shown in C), a workpiece abutting portion 210 is provided. The workpiece abutting portion 210 is a portion that is fitted to the erection rod portion 92 of the U-shaped fastener 90 and abuts against the erection rod portion 92 from above in the drawing, and has a width that allows the erection rod portion 92 to be detachably fitted. A cross-sectional shape that opens downward in the figure at a depth is formed in a substantially U-shape. In this case, the workpiece abutting portion 210 is formed to have a length substantially the same as the length of the erection rod portion 92 (slightly shorter length in the present embodiment), and the left and right ends in the drawing are in the horizontal direction in the drawing. Open. A hammer fitting portion 220 is formed on the upper portion of the workpiece abutting portion 210 in the figure.

ハンマー嵌合部２２０は、Ｕ字留め具９０に打撃を加える電動ハンマー４００におけるハンマー４０２が着脱自在に接続される部分であり、ワーク突き当て部２１０に対して図示上方に向かって延びる円筒状に形成されている。このハンマー嵌合部２２０は、電動ハンマー４００におけるハンマー４０２が着脱自在かつ摺動自在に嵌合する摺動部２２１と、この摺動部２２１より小径の貫通部２２２とで構成されており、これら摺動部２２１と貫通部２２２との間の段部がハンマー受け部２２３として構成されている。ハンマー受け部２２３は、ハンマー４０２による打撃を受ける部分であり、ハンマー嵌合部２２０内においてリング状に形成されている。このハンマー受け部２２３は、後述する延長壁部２２４が形成された図示上下方向の範囲内、換言すれば延長壁部２２４の内側の領域内に形成される。   The hammer fitting portion 220 is a portion to which the hammer 402 of the electric hammer 400 that strikes the U-shaped fastener 90 is detachably connected, and has a cylindrical shape that extends upward in the figure with respect to the workpiece abutting portion 210. Is formed. The hammer fitting portion 220 includes a sliding portion 221 into which the hammer 402 of the electric hammer 400 is detachably and slidably fitted, and a through portion 222 having a smaller diameter than the sliding portion 221. A step portion between the sliding portion 221 and the penetrating portion 222 is configured as a hammer receiving portion 223. The hammer receiving portion 223 is a portion that receives a hit by the hammer 402 and is formed in a ring shape in the hammer fitting portion 220. The hammer receiving portion 223 is formed in a range in the illustrated vertical direction in which an extension wall portion 224 to be described later is formed, in other words, in a region inside the extension wall portion 224.

ハンマー嵌合部２２０の外周部は、平面視において略平行四辺形（本実施形態においては、ひし形（斜方形））に形成されている。より具体的には、ハンマー嵌合部２２０の外周部は、ワーク突き当て部２１０の長手方向に直交する方向の長さ、すなわち、ハンマー嵌合部２２０の外周部の幅が最も厚い部分でワーク突き当て部２１０の幅（長手方向に直交する方向の長さ）と同じ長さに形成されている。一方、ハンマー嵌合部２２０の外周部におけるワーク突き当て部２１０の長手方向は、後述する従側案内嵌合部２３０まで延びて形成されており延長壁部２２４を構成している。   The outer peripheral portion of the hammer fitting portion 220 is formed in a substantially parallelogram shape (in the present embodiment, a rhombus (rhombic shape)) in plan view. More specifically, the outer peripheral portion of the hammer fitting portion 220 has a length in a direction orthogonal to the longitudinal direction of the workpiece abutting portion 210, that is, a portion where the width of the outer peripheral portion of the hammer fitting portion 220 is the thickest. The abutting portion 210 is formed to have the same length as the width (the length in the direction orthogonal to the longitudinal direction). On the other hand, the longitudinal direction of the workpiece abutting portion 210 at the outer peripheral portion of the hammer fitting portion 220 is formed to extend to a slave guide fitting portion 230 described later, and constitutes an extended wall portion 224.

延長壁部２２４は、主として、ハンマー４０２の打撃音を緩和するための中実の部分であり、ハンマー嵌合部２２０からワーク突き当て部２１０の長手方向外側に向かってワーク突き当て部２１０の幅（長手方向に直交する長さ）の半分の長さよりも長い長さの壁状に形成されている。この場合、延長壁部２２４は、ハンマー嵌合部２２０における先端部、すなわち、ハンマー嵌合部２２０が開口する打込み治具２００の図示上端面から従側案内嵌合部２３０側（図示下方に）に向かって広がって形成されている。
The extension wall portion 224 is mainly a solid portion for reducing the hammering sound of the hammer 402, and the width of the workpiece abutting portion 210 from the hammer fitting portion 220 toward the outside in the longitudinal direction of the workpiece abutting portion 210. It is formed in the shape of a wall having a length longer than half the length (the length perpendicular to the longitudinal direction). In this case, the extension wall portion 224 is located at the distal end portion of the hammer fitting portion 220, that is, from the upper end surface of the driving jig 200 where the hammer fitting portion 220 opens to the slave guide fitting portion 230 side (downward in the drawing). It is formed to spread toward.

換言すれば、延長壁部２２４は、ハンマー嵌合部２２０における先端部から図示水平方向に延びた後、長手方向外側に向かって高さが低くなるように形成されている。また、この延長壁部２２４は、ハンマー嵌合部２２０側からワーク突き当て部２１０の長手方向外側（本実施形態においては従側案内嵌合部２３０）に向かって厚さが薄くなるように形成されている。   In other words, the extension wall portion 224 is formed so as to extend in the horizontal direction in the drawing from the tip portion of the hammer fitting portion 220 and then decrease in height toward the outside in the longitudinal direction. Further, the extension wall portion 224 is formed so that its thickness decreases from the hammer fitting portion 220 side toward the outside in the longitudinal direction of the workpiece abutting portion 210 (in this embodiment, the secondary guide fitting portion 230). Has been.

ワーク突き当て部２１０における長手方向両端部には、従側案内嵌合部２３０がそれぞれ形成されている。従側案内嵌合部２３０は、Ｕ字留め具９０を設置対象個所Ｇに打ち込む際に打込み治具２００を打込み方向に案内するための部分であり、ワーク突き当て部２１０の両端部からそれぞれ長手方向外側に向かって凸状に突出して形成されている。この場合、各従側案内嵌合部２３０は、後述する主側案内嵌合部３０２に対して着脱自在かつ摺動自在に嵌合する四角棒状に形成されている。   Subordinate guide fitting portions 230 are formed at both ends in the longitudinal direction of the workpiece abutting portion 210. The subordinate guide fitting portion 230 is a portion for guiding the driving jig 200 in the driving direction when driving the U-shaped fastener 90 into the installation target location G, and extends from both ends of the workpiece abutting portion 210. It protrudes in a convex shape toward the outside in the direction. In this case, each subordinate guide fitting portion 230 is formed in a square bar shape that is detachably and slidably fitted to a main side guide fitting portion 302 described later.

この打込み治具２００は、鋼材に対してフライス加工などの機械加工を行うことによってワーク突き当て部２１０、ハンマー嵌合部２２０および従側案内嵌合部２３０を一体的に成形して製作される。本実施形態においては、打込み治具２００は、炭素鋼（例えば、Ｓ５０Ｃ）によって構成されている。この場合、打込み治具２００は、ハンマー嵌合部２２０にのみ焼入れ処理などの熱処理を行って表面硬度を上昇させておくとよい。   The driving jig 200 is manufactured by integrally forming the workpiece abutting portion 210, the hammer fitting portion 220, and the slave guide fitting portion 230 by performing machining such as milling on a steel material. . In the present embodiment, the driving jig 200 is made of carbon steel (for example, S50C). In this case, the driving jig 200 may increase the surface hardness by performing a heat treatment such as a quenching process only on the hammer fitting portion 220.

打込みガイド３００は、図１（Ａ）〜（Ｃ）に示すように、打込み治具２００を設置対象個所Ｇに向かって案内するための器具であり、２つのガイド体３０１を備えている。ガイド体３０１は、打込み治具２００における２つの従側案内嵌合部２３０がそれぞれ着脱自在かつ摺動自在に嵌合されて案内する部分であり、図示上下方向に沿って互いに平行に延びる柱状に形成されている。これら２つのガイド体３０１における互いの対向面には、各従側案内嵌合部２３０が摺動自在に嵌合する凹状に凹んだ主側案内嵌合部３０２がそれぞれ形成されている。   As shown in FIGS. 1A to 1C, the driving guide 300 is an instrument for guiding the driving jig 200 toward the installation target location G, and includes two guide bodies 301. The guide body 301 is a portion in which the two secondary guide fitting portions 230 of the driving jig 200 are detachably and slidably fitted to each other, and are guided in a columnar shape extending in parallel with each other along the vertical direction in the figure. Is formed. On the opposing surfaces of the two guide bodies 301, a main guide fitting portion 302 that is recessed in a concave shape to which each of the secondary guide fitting portions 230 is slidably fitted is formed.

そして、これらの２つのガイド体３０１は、連結部３０３によって互いに連結されている。連結部３０３は、２つのガイド体３０１の平行状態を維持した状態で互いに連結する部分であり、２つのガイド体３０１における図示下端部側および図示上端部側にそれぞれ形成されている。この場合、図示下端部側に設けられた連結部３０３は、打込みガイド３００の前方側に張り出して設けられている。また、ガイド体３０１における図示上端部側に設けられた連結部３０３は、打込みガイド３００の後方側に張り出して設けられている。   And these two guide bodies 301 are mutually connected by the connection part 303. FIG. The connecting portion 303 is a portion for connecting the two guide bodies 301 to each other while maintaining the parallel state, and is formed on the illustrated lower end side and the illustrated upper end side of the two guide bodies 301, respectively. In this case, the connecting portion 303 provided on the lower end side in the figure is provided so as to protrude to the front side of the driving guide 300. In addition, the connecting portion 303 provided on the upper end portion side of the guide body 301 is provided so as to protrude to the rear side of the driving guide 300.

これらの連結部３０３は、棒部３０３ａと筒部３０３ｂとでそれぞれ構成されている。棒部３０３ａは、２つのガイド体３０１のうちの一方からから張り出した後、他方のガイド体３０１側に屈曲して延びる棒体である。また、筒部３０３ｂは、棒部３０３ａが設けられたガイド体３０１とは異なる前記他方のガイド体３０１から張り出して棒部３０３ａが貫通する筒体を備えて構成されている。この場合、筒部３０３ｂは、セットボルト３０３ｃを備えており、貫通する棒部３０３ａの固定位置を調整することができる。すなわち、２つのガイド体３０１は、互いの間隔が調節可能に連結されている。
These connection parts 303 are each comprised by the rod part 303a and the cylinder part 303b. The rod portion 303a is a rod body that protrudes from one of the two guide bodies 301 and then bends and extends toward the other guide body 301 side. Moreover, the cylinder part 303b is provided with the cylinder body which protrudes from the said other guide body 301 different from the guide body 301 in which the rod part 303a was provided, and the rod part 303a penetrates. In this case, the cylinder part 303b is provided with a set bolt 303c, and the fixing position of the penetrating rod part 303a can be adjusted. That is, the two guide bodies 301 are connected so that the interval between them can be adjusted.

また、２つのガイド体３０１には、前記後方側に向かって張り出す連結部３０３の図示下方にハンドル３０４がそれぞれ設けられている。ハンドル３０４は、打込みガイド３００の移動や位置決め、およびＵ字留め具９０の打ち込み作業時に打込みガイド３００の位置ずれや傾倒を防止するために作業者が把持する部分であり、各ガイド体３０１から張り出した後、図示上側に屈曲して延びて形成されている。この打込みガイド３００は、アングル状、棒状および板状の鋼材をそれぞれ互いに溶接加工することによって製作される。   The two guide bodies 301 are respectively provided with handles 304 below the connecting portion 303 that projects toward the rear side. The handle 304 is a portion that is gripped by the operator in order to prevent the displacement and tilting of the driving guide 300 during the movement and positioning of the driving guide 300 and the driving operation of the U-shaped fastener 90, and protrudes from each guide body 301. Then, it is formed to bend and extend upward in the figure. The driving guide 300 is manufactured by welding each of an angle-shaped, bar-shaped and plate-shaped steel materials.

（打込み用具１００の作動）
次に、上記のように構成した打込み用具１００の作動について説明する。まず、Ｕ字留め具９０の設置作業を行う作業者は、Ｕ字留め具９０の他に、打込み治具２００と打込みガイド３００とからなる打込み用具１００、および電動ハンマー４００をそれぞれ用意する。この場合、電動ハンマー４００は、Ｕ字留め具９０を打撃するための公知の機器であり、主として本体部４０１とハンマー４０２とを備えて構成されている。本体部４０１は、ハンマー４０２を駆動する電動機、電動機を制御する制御回路、電源回路、操作スイッチおよびハンドルなどを備えて構成されている。また、ハンマー４０２は、本体部４０１が備える電動機の駆動によって図示上下方向に往復動する鋼製の円柱体である。なお、図１（Ａ）においては、電動ハンマー４００における本体部４０１を省略するとともにハンマー４０２を破断した状態で示している。 (Operation of driving tool 100)
Next, the operation of the driving tool 100 configured as described above will be described. First, an operator who performs the installation work of the U-shaped fastener 90 prepares the driving tool 100 including the driving jig 200 and the driving guide 300 and the electric hammer 400 in addition to the U-shaped fastener 90. In this case, the electric hammer 400 is a known device for hitting the U-shaped fastener 90, and mainly includes a main body 401 and a hammer 402. The main body 401 includes an electric motor that drives the hammer 402, a control circuit that controls the electric motor, a power supply circuit, an operation switch, a handle, and the like. The hammer 402 is a steel cylinder that reciprocates in the vertical direction in the figure by driving an electric motor included in the main body 401. In FIG. 1A, the main body 401 of the electric hammer 400 is omitted and the hammer 402 is shown in a broken state.

次に、作業者は、設置対象個所Ｇ上に打込みガイド３００を配置した後、Ｕ字留め具９０を２つのガイド体３０１に図示上端部からそれぞれ挿入して設置対象個所Ｇ上に配置する。次に、作業者は、打込み治具２００における２つの従側案内嵌合部２３０を２つのガイド体３０１に図示上端部からそれぞれ挿入してＵ字留め具９０上に位置させる。これにより、打込み治具２００は、ワーク突き当て部２１０内にＵ字留め具９０の架設棒部９２が嵌合して突き当てられる。なお、作業者は、Ｕ字留め具９０および打込み治具２００に対して２つのガイド体３０１の間隔が不適当であると判断した場合には、セットボルト３０３ｃを弛めることにより２つのガイド体３０１間の間隔を適宜調整することができる。
Next, the worker, after placing the implant guide 300 on an installation object pieces plant G, disposed on the installation target number office G inserting them from the shown upper end a U-shaped fastener 90 into two guide member 301 To do. Next, the operator inserts the two slave guide fitting portions 230 in the driving jig 200 into the two guide bodies 301 from the upper end portions in the drawing and positions them on the U-shaped fastener 90. As a result, the driving jig 200 is abutted by fitting the construction bar portion 92 of the U-shaped fastener 90 into the workpiece abutting portion 210. When the operator determines that the interval between the two guide bodies 301 is inappropriate for the U-shaped fastener 90 and the driving jig 200, the two guide bodies 301 are loosened by loosening the set bolts 303c. The interval between them can be adjusted as appropriate.

次に、作業者は、打込み治具２００におけるハンマー嵌合部２２０内に電動ハンマー４００におけるハンマー４０２の先端部を挿入してハンマー４０２と打込み治具２００のハンマー嵌合部２２０とを接続する。そして、作業者は、Ｕ字留め具９０の打込み作業を開始する。具体的には、作業者は、電動ハンマー４００を図示しない電源に接続した後、電動ハンマー４００の電源をＯＮにすることにより作動を開始させる。   Next, the operator inserts the tip of the hammer 402 of the electric hammer 400 into the hammer fitting portion 220 of the driving jig 200 to connect the hammer 402 and the hammer fitting portion 220 of the driving jig 200. Then, the worker starts driving operation of the U-shaped fastener 90. Specifically, the operator starts the operation by connecting the electric hammer 400 to a power source (not shown) and then turning on the electric hammer 400.

これにより、打込み治具２００は、ハンマー嵌合部２２０内のハンマー受け部２２３が電動ハンマー４００のハンマー４０２によって打撃されることによってＵ字留め具９０の架設棒部９２を打撃する。この場合、打込み治具２００は、ハンマー嵌合部２２０の外側に長手方向に沿って延長壁部２２４が形成されているため、打撃による衝撃の一部を吸収して緩和しながらＵ字留め具９０を打ち込むことができる。また、打込み治具２００は、延長壁部２２４によって打込み治具２００の剛性が高められているため、ハンマー４０２の打撃による損傷および劣化が抑えられて耐久性が向上する。   Accordingly, the driving jig 200 hits the construction bar portion 92 of the U-shaped fastener 90 by hitting the hammer receiving portion 223 in the hammer fitting portion 220 with the hammer 402 of the electric hammer 400. In this case, since the extension jig 224 is formed on the outside of the hammer fitting portion 220 along the longitudinal direction, the driving jig 200 absorbs a part of the impact caused by the impact and relaxes the U-shaped fastener. 90 can be typed. Moreover, since the rigidity of the driving jig 200 is enhanced by the extension wall portion 224, the driving jig 200 can be prevented from being damaged and deteriorated by the hammer 402, and the durability is improved.

このＵ字留め具９０の打込み作業においては、Ｕ字留め具９０が設置対象個所Ｇ内に打込まれるごとに打込み治具２００における従側案内嵌合部２３０が打込みガイド３００における主側案内嵌合部３０２内を摺動して図示下方に下降していく（図示破線矢印参照）。そして、設置対象個所Ｇ内にＵ字留め具９０が打ち込まれた場合には、作業者は、打込み治具２００におけるハンマー嵌合部２２０内からハンマー４０２の先端部を引抜いてハンマー４０２を取り外す。次いで、作業者は、打込み治具２００の従側案内嵌合部２３０を主側案内嵌合部３０２から抜きながら打込みガイド３００を設置対象個所Ｇから撤去した後、設置対象個所Ｇに打込まれたＵ字留め具９０の架設棒部９２上から打込み治具２００を撤去する。これにより、作業者は、Ｕ字留め具９０の打込み作業を終了することができる。
In driving operation of the U-shaped fastener 90, the main side guide in detail side guide fitting portion 230 is driving guide 300 in driving jig 200 each time the U-shaped fastener 90 is driven into the installation target number plants in G It slides in the fitting portion 302 and descends downward in the figure (see broken arrow in the figure). When the U-shaped fastener 90 has been driven to the installation target number plants in G, the operator removes the hammer 402 by pulling out the leading end of the hammer 402 from the hammer engaging portion 220. in driving jig 200 . Then, the operator, after removing the implant guide 300 while venting from the implanted primary side guide fitting portion 302 a detail side guide fitting portion 230 of the jig 200 from the setting target number plants G, striking the installation target pieces plant G The driving jig 200 is removed from the construction bar portion 92 of the inserted U-shaped fastener 90. Thereby, the operator can finish the driving operation of the U-shaped fastener 90.

上記作動説明からも理解できるように、上記実施形態によれば、打込み治具２００は、Ｕ字留め具９０に打撃を加える柱状のハンマー４０２が摺動自在に嵌合するハンマー嵌合部２２０に延長壁部２２４がワーク突き当て部２１０の長手方向に沿って同ワーク突き当て部２１０の幅よりも長い長さで張り出して形成されている。これにより、打込み治具２００は、ハンマー４０２によって打撃される部分の周囲の一部に設けられた延長壁部２２４がハンマー４０２の打撃による衝撃の一部を吸収するため、Ｕ字留め具９０の打込み作業時における騒音や振動を抑えることができる。   As can be understood from the above description of operation, according to the embodiment, the driving jig 200 is attached to the hammer fitting portion 220 into which the columnar hammer 402 that strikes the U-shaped fastener 90 is slidably fitted. The extension wall portion 224 is formed to protrude along the longitudinal direction of the workpiece abutting portion 210 with a length longer than the width of the workpiece abutting portion 210. As a result, in the driving jig 200, the extension wall portion 224 provided in a part of the periphery of the portion hit by the hammer 402 absorbs a part of the impact caused by the hammer 402 hitting. Noise and vibration during driving operation can be suppressed.

さらに、本発明の実施にあたっては、上記実施形態に限定されるものではなく、本発明の目的を逸脱しない限りにおいて種々の変更が可能である。   Furthermore, in carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention.

例えば、上記実施形態においては、打込み治具２００は、Ｓ５０Ｃの炭素鋼で構成した。しかし、打込み治具２００は、電動ハンマー４００の打撃に耐えてＵ字留め具９０を打ち込むことができる材料で構成されていれば、上記実施形態に限定されるものではない。したがって、打込み治具２００は、Ｓ５０Ｃ以外の炭素鋼（例えば、ＳＫ材、ＳＫＳ材、ＳＫＤ材）などを用いることができるほか、炭素鋼以外の金属材料、例えば、炭素が含まれていない所謂生材（ＳＳ材）や鋳鉄などを用いて構成することができる。この場合、本発明者の実験によれば、打込み治具２００は、炭素鋼で構成することによって他の金属材料、具体的には、鋳鉄で構成する場合に比べてＵ字留め具９０の打込み作業時における騒音および振動を抑えることができることを確認した。   For example, in the above embodiment, the driving jig 200 is made of S50C carbon steel. However, the driving jig 200 is not limited to the above embodiment as long as it is made of a material that can withstand the hit of the electric hammer 400 and can drive the U-shaped fastener 90. Therefore, the driving jig 200 can use carbon steel other than S50C (for example, SK material, SKS material, SKD material) and the like, and can also use a metal material other than carbon steel, for example, so-called raw material that does not contain carbon. A material (SS material) or cast iron can be used. In this case, according to the experiment of the present inventor, the driving jig 200 is made of carbon steel, so that the U-shaped fastener 90 is driven as compared with the case where it is made of another metal material, specifically, cast iron. It was confirmed that noise and vibration during work can be suppressed.

また、上記実施形態においては、打込み治具２００は、延長壁部２２４がハンマー嵌合部２２０の先端部（打込み治具２００の図示上面）からワーク突き当て部２１０までの間の領域に連続的に形成した。この場合、ワーク突き当て部２１０までの間とは、ワーク突き当て部２１０におけるＵ字留め具９０が突き当てられる部分を構成する部分までの間、または同突き当てられる部分がハンマー４０２の打撃に耐えることができる肉厚を介した上面上までの間をいう。これにより、延長壁部２２４は、Ｕ字留め具９０の打込み作業時における騒音および振動をより効果的に抑えることができるとともに打込み治具２００の耐久性をより効果的に向上させることができる。しかし、延長壁部２２４は、ハンマー受け部２２３の少なくとも近傍に形成されていればよいため、必ずしもハンマー嵌合部２２０の先端部の高さまで形成する必要はない。
In the above embodiment, the driving jig 200 has the extension wall portion 224 in the region between the tip end portion of the hammer fitting portion 220 (the upper surface in the drawing of the driving jig 200) and the workpiece abutting portion 2 10. Formed continuously. In this case, the until workpiece abutting section 2 1 0, until the portion constituting the devoted portion abutting the U-shaped fastener 90 in the workpiece abutting section 2 1 0 or the abutted portion, hammer It refers to the interval up to the upper surface through the thickness that can withstand the hit of 402. Thereby, the extension wall part 224 can suppress more effectively the noise and vibration at the time of driving operation of the U-shaped fastener 90, and can improve the durability of the driving jig 200 more effectively. However, since the extension wall portion 224 only needs to be formed in the vicinity of the hammer receiving portion 223, it is not always necessary to form the extension wall portion 224 up to the height of the tip end portion of the hammer fitting portion 220.

また、上記実施形態においては、打込み治具２００は、延長壁部２２４がハンマー嵌合部２２０の先端部側からワーク突き当て部２１０側に向かって広がって形成されている。これにより、延長壁部２２４は、Ｕ字留め具９０の打ち込み時における打撃音や振動を抑えながら打込み治具２００自体の重量を軽量化することができる。しかし、延長壁部２２４は、ハンマー受け部２２３の近傍に形成されていればよいため、例えば、ハンマー嵌合部２２０の先端部側から同じ高さでワーク突き当て部２１０の各端部または従側案内嵌合部２３０の各端部まで延びて形成することもできる。これによれば、延長壁部２２４は、Ｕ字留め具９０の打ち込み時における打撃音や振動をより効果的に抑えることができる。   Further, in the above embodiment, the driving jig 200 is formed such that the extension wall portion 224 extends from the tip end portion side of the hammer fitting portion 220 toward the workpiece abutting portion 210 side. Thereby, the extension wall part 224 can reduce the weight of the driving jig 200 itself while suppressing the hitting sound and vibration when the U-shaped fastener 90 is driven. However, since the extension wall portion 224 only needs to be formed in the vicinity of the hammer receiving portion 223, for example, each end portion or subordinate portion of the workpiece abutting portion 210 is at the same height from the tip end side of the hammer fitting portion 220. It can also be formed to extend to each end of the side guide fitting portion 230. According to this, the extension wall part 224 can suppress the impact sound and vibration at the time of driving in the U-shaped fastener 90 more effectively.

また、上記実施形態においては、打込み治具２００は、延長壁部２２４がハンマー嵌合部２２０内におけるハンマー受け部２２３の外側に形成した。これにより、打込み治具２００は、ハンマー４０２の打撃音や振動を効果的に抑えることができる。しかし、延長壁部２２４は、ハンマー受け部２２３の近傍に形成されていればよく、ハンマー受け部２２３に対して図示上方または図示下方に形成されていてもよい。   In the above embodiment, the driving jig 200 has the extension wall portion 224 formed outside the hammer receiving portion 223 in the hammer fitting portion 220. Thereby, the driving jig 200 can effectively suppress the hitting sound and vibration of the hammer 402. However, the extension wall portion 224 only needs to be formed in the vicinity of the hammer receiving portion 223, and may be formed above or below the hammer receiving portion 223 in the drawing.

また、上記実施形態においては、打込み治具２００は、ワーク突き当て部２１０の両端部に同ワーク突き当て部２１０の長手方向にそれぞれ凸状に張り出した状態で従側案内嵌合部２３０が形成した。しかし、この従側案内嵌合部２３０は、ガイド体３０１に嵌合して案内されるように構成されていれば、必ずしも上記実施形態に限定されるものではない。したがって、従側案内嵌合部２３０は、ワーク突き当て部２１０の両端部に同ワーク突き当て部２１０の長手方向にそれぞれ凹状に凹んだ状態で形成することもできる（図示せず）。この場合、この場合、２つのガイド体３０１における互いの対向面には、各従側案内嵌合部２３０が摺動自在に嵌合する凸状に張り出した主側案内嵌合部３０２がそれぞれ形成される。   Further, in the above embodiment, the driving jig 200 is formed with the secondary guide fitting portion 230 in a state of projecting in the longitudinal direction of the workpiece abutting portion 210 at both ends of the workpiece abutting portion 210. did. However, the subordinate guide fitting portion 230 is not necessarily limited to the above embodiment as long as it is configured to be fitted and guided to the guide body 301. Therefore, the slave side guide fitting part 230 can also be formed in the both-ends part of the workpiece | work abutting part 210 in the state dented in the longitudinal direction of the said workpiece | work abutting part 210, respectively (not shown). In this case, on the opposing surfaces of the two guide bodies 301, the main guide fitting portions 302 projecting in a convex shape are formed, on which the respective slave guide fitting portions 230 are slidably fitted. Is done.

また、上記実施形態においては、打込み治具２００は、ワーク突き当て部２１０の長手方向（図示左右方向）両端部を解放して形成した。これにより、打込み治具２００をＵ字留め具９０の架設棒部９２に嵌める際の位置決めが容易となるとともに、幅広い大きさのＵ字留め具９０に１つの打込み治具２００を流用することができる。しかし、打込み治具２００は、ワーク突き当て部２１０の長手方向（図示左右方向）両端部を閉塞して構成することもできることは当然である。   In the above embodiment, the driving jig 200 is formed by releasing both ends of the workpiece abutting portion 210 in the longitudinal direction (left-right direction in the drawing). This facilitates positioning when fitting the driving jig 200 into the construction bar portion 92 of the U-shaped fastener 90, and allows one driving jig 200 to be used for the U-shaped fastener 90 having a wide size. it can. However, it is natural that the driving jig 200 can be configured by closing both ends in the longitudinal direction (the left-right direction in the drawing) of the workpiece abutting portion 210.

また、上記実施形態においては、打込み用具１００は、鉄道の道床を構成するバラスト袋にＵ字留め具９０を打ち込んだ。しかし、打込み用具１００は、Ｕ字留め具９０を打ち込む際に使用されるものであって、打ち込む対象はバラスト袋以外であってもよいことは当然である。すなわち、打込み用具１００は、例えば、地中に埋設した管を固定するためのＵ字留め具９０を打ち込む際に使用することもできる。また、この打込み用具１００を構成する打込み治具２００は、打込みガイド３００や電動ハンマー４００を使用せず、直接Ｕ字留め具９０上に配置することともにハンマー嵌合部２２０内に棒体を挿し込んで、この棒体を手作業で打撃してＵ字留め具９０を打ち込むようにすることもできる。   In the above-described embodiment, the driving tool 100 drives the U-shaped fastener 90 into the ballast bag that forms the railroad bed. However, the driving tool 100 is used when driving the U-shaped fastener 90, and the target to be driven may be other than the ballast bag. That is, the driving tool 100 can be used, for example, when driving a U-shaped fastener 90 for fixing a pipe buried in the ground. Further, the driving jig 200 constituting the driving tool 100 is arranged directly on the U-shaped fastener 90 without using the driving guide 300 or the electric hammer 400, and a rod body is inserted into the hammer fitting portion 220. The U-shaped fastener 90 can be driven by manually hitting this rod.
