Description

本発明は、空頭制限がある作業領域にて使用可能な重量物建込装置に関する。   The present invention relates to a heavy-duty construction device that can be used in a work area where there is a sky head limitation.

例えば、地中連続壁を構築する場合には、特許文献1に開示されているようなクローラークレーンにて地中を掘削して設けた掘削溝の直上に鉄筋籠を配置し、先行して掘削溝内へ挿入されている鉄筋籠との継ぎ足しを行いつつ挿入する工程を繰り返し、所望の高さとなるまで継ぎ足した複数の鉄筋籠を建て込んだ後、掘削溝内にコンクリートを打設する方法が知られている。   For example, when building an underground continuous wall, a rebar is placed immediately above the excavation groove provided by excavating the underground with a crawler crane as disclosed in Patent Document 1, and excavated in advance. There is a method in which a concrete is placed in an excavation groove after a plurality of reinforcement rods that have been added to a desired height are built by repeating the insertion process while adding the reinforcement rods inserted into the groove. Are known.

引用文献1で開示されているようなクローラークレーンは、大きい高さに組み立てられた超重量の鉄筋籠を吊持することができるため、効率よく鉄筋籠の建込作業を行うことができるが、作業領域に空頭制限があると使用できない場合が生じる。このため、作業領域が低空頭である場合には、ベースマシンに空頭制限を満足する高さのリーダーを備えたリーダー式昇降機を設置し、これらリーダー式昇降機にて鉄筋籠の建込みを行うなどしていた。   Since the crawler crane as disclosed in the cited document 1 can suspend a super-weight rebar bar assembled to a large height, it can efficiently perform the work of building the rebar bar. If the work area has an empty head limit, it may not be used. For this reason, when the work area is low-headed, install a leader-type elevator equipped with a leader with a height that satisfies the head-of-head restriction on the base machine, and build a reinforcing bar with these leader-type elevators. Was.

しかし、上記のベースマシンとリーダー式昇降機にて鉄筋籠を吊持する方法では、鉄筋籠の重量に応じてベースマシンのサイズを変更する必要があり、超重量の鉄筋籠を吊持しようとするとベースマシンも大型化することから、空頭制限はもとより作業帯幅に収まらない事態となりやすい。また、リーダー式昇降機のストロークによって鉄筋籠の高さにも制限が生じることから、鉄筋籠を製作するにあたりその大きさや重量を、使用するベースマシンとリーダー式昇降機に対応できるように配慮しなければならず、鉄筋籠の継ぎ足し作業回数が増加する等、施工性に影響が生じていた。さらに、ベースマシンとリーダー式昇降機による鉄筋籠の建込作業では、吊持した状態で重量物の平面位置を微調整できないことから、別途位置出し作業を実施するため多大な時間を要するだけでなく、精度よく建て込むための作業が煩雑となっていた。   However, in the method of suspending the reinforcing bar rod with the above base machine and the leader type elevator, it is necessary to change the size of the base machine according to the weight of the reinforcing rod rod. Since the base machine is also increased in size, it is prone to a situation that does not fall within the working band width as well as the limited head. In addition, the height of the reinforcing bar is also limited by the stroke of the leader type elevator. Therefore, when manufacturing the reinforcing bar, the size and weight must be considered so as to be compatible with the base machine and leader type elevator used. However, the workability was affected, for example, the number of times of rebar reinforcement work was increased. Furthermore, in the construction work of the reinforcing bar with the base machine and the leader type elevator, the plane position of the heavy load cannot be finely adjusted in the suspended state, so it takes not only a great deal of time to perform the separate positioning work. Therefore, the work for accurately building is complicated.

本発明は、かかる課題に鑑みなされたものであって、その主な目的は、作業領域が狭隘でかつ空頭制限がある場合にも、所望の重量を有する重量物を吊持可能であるとともに、重量物を建て込む際の位置出しを容易に行うことの可能な重量物建込装置を提供することである。   The present invention has been made in view of such problems, and its main purpose is to be able to suspend a heavy object having a desired weight even when the work area is narrow and there is a sky head limitation, It is an object of the present invention to provide a heavy-duty construction device capable of easily performing positioning when constructing a heavy article.

かかる目的を達成するため、本発明の重量物建込装置は、間隔をおいて並列配置される一対の走行体と、該一対の走行体各々の走行方向前後に配置される脚部と、前記走行体の走行方向と直交する方向に隣り合う該脚部どうしを連結する一対の上部連結部材と、該一対の上部連結部材に平面位置調整装置を介して垂下される吊持装置と、を備え、前記脚部が、鉛直方向に伸縮する伸縮装置を有し、前記平面位置調整装置が、前記吊持装置を前記走行体の走行方向及び走行方向と直交する方向に移動させる移動手段を有することを特徴とする。   In order to achieve such an object, the heavy-duty construction device of the present invention includes a pair of traveling bodies arranged in parallel at intervals, leg portions disposed before and after the traveling direction of each of the pair of traveling bodies, A pair of upper connecting members that connect the leg portions adjacent to each other in a direction orthogonal to the traveling direction of the traveling body, and a suspension device that is suspended from the pair of upper connecting members via a planar position adjusting device. The leg portion has a telescopic device that expands and contracts in the vertical direction, and the planar position adjusting device has a moving means for moving the suspension device in a traveling direction of the traveling body and a direction orthogonal to the traveling direction. It is characterized by.

上記の重量物建込装置によれば、重量物を吊持する吊持装置が、重量物建込装置を構成する4体の脚部の内方であって一対の上部連結部材の下方に配置される。したがって、吊持装置を平面視で4体の脚部の略中央に配置し、櫓をなすように4体の脚部の配置間隔を十分取ることにより、作業領域が狭隘でかつ空頭制限がある場合にも、所望の重量を有する重量物を安全に搬送でき、かつ効率よく建込作業を行うことが可能となる。   According to the above-described heavy-duty construction device, the suspension device that suspends the heavy material is disposed inside the four legs constituting the heavy-duty construction device and below the pair of upper connecting members. Is done. Accordingly, the suspension device is arranged in the approximate center of the four legs in plan view, and the working space is narrow and the head is limited by sufficiently arranging the arrangement of the four legs so as to form a heel. Even in this case, it is possible to safely transport a heavy object having a desired weight and efficiently perform the erection work.

また、吊持装置が、平面位置調整装置により走行体の走行方向および走行方向と直交する方向へ移動するため、走行体にて重量物建込装置自体を移動することなく、吊持装置にて吊持された重量物の平面位置を微調整でき、重量物を建て込む際の作業性および建込み精度を大幅に向上することが可能となる。   In addition, since the suspension device moves in the traveling direction of the traveling body and the direction orthogonal to the traveling direction by the planar position adjusting device, the suspension device does not move the heavy article building device itself in the traveling body. The planar position of the suspended heavy object can be finely adjusted, and the workability and installation accuracy when building a heavy object can be greatly improved.

また、本発明の重量物建込装置は、前記吊持装置が、鉛直方向に伸縮する伸縮装置と、該伸縮装置を中心軸として水平面内で回転する吊り治具を備えることを特徴とする。   In the heavy-duty construction apparatus according to the present invention, the suspension device includes a telescopic device that expands and contracts in a vertical direction, and a hanging jig that rotates in a horizontal plane with the telescopic device as a central axis.

上記の重量物建込装置によれば、吊り治具が鉛直方向に伸縮する伸縮装置に備えられることから、吊り治具の鉛直方向における可動範囲は、前記脚部の伸縮量に伸縮装置の伸縮量が加算された量となるため、脚部のみが伸縮する場合と比較して、より高さの大きい重量物を吊り治具にて吊持することが可能となる。   According to the heavy construction apparatus, since the suspension jig is provided in an expansion / contraction device that expands / contracts in the vertical direction, the movable range of the suspension jig in the vertical direction can be expanded / contracted by the expansion / contraction amount of the leg portion. Since the amount is an added amount, it is possible to suspend a heavy object with a height higher than that when only the leg portion expands and contracts with the lifting jig.

また、吊持装置に備えた伸縮装置に対して吊り治具が水平面内で回転することから、吊持した重量物の平面位置を、伸縮装置を中心とした水平回転方向にも微調整することが可能となる。   In addition, since the suspension jig rotates in a horizontal plane with respect to the expansion / contraction device provided in the suspension device, the planar position of the suspended heavy object can be finely adjusted in the horizontal rotation direction around the expansion / contraction device. Is possible.

本発明の重量物建込装置によれば、重量物を吊持する吊持装置が、上部連結部材に平面位置調整装置を介して設置され、また4体の脚部の略中央に配置できるため、作業領域が狭隘でかつ空頭制限がある場合にも、超重量の重量物を吊持することが可能であるとともに、重量物を建て込む際の位置出しを容易に行うことが可能となる。   According to the heavy-duty construction device of the present invention, the suspension device for suspending heavy objects is installed on the upper connecting member via the planar position adjustment device, and can be arranged at the approximate center of the four leg portions. Even when the work area is narrow and the head is limited, it is possible to suspend a very heavy object and to easily position the object when building the heavy object.

本発明の重量物建込装置は、低空頭で狭隘な作業領域において、鉄筋籠、構真柱、プレキャスト部材等の重量物を搬送可能で、かつ、これら重量物を地盤中に設けた掘削領域へ挿入し建込む際の、平面位置の微調整を行うことの可能な装置である。本実施の形態では、重量物として地中連続壁や場所打ちコンクリート杭等を構築する際に用いる鉄筋籠を事例に挙げ、以下に、重量物建込装置1を図1〜図5を参照しつつ説明する。   The heavy-duty construction apparatus of the present invention is capable of transporting heavy objects such as reinforcing bar, structural pillar, precast member, etc., in a low-altitude and narrow work area, and an excavation area in which these heavy objects are provided in the ground It is a device that can finely adjust the plane position when it is inserted and built. In this embodiment, a steel bar used when constructing underground continuous walls, cast-in-place concrete piles, etc. as heavy objects is taken as an example, and the heavy object building device 1 will be described below with reference to FIGS. I will explain.

図1で示すように、重量物建込装置1は、地盤上に設置されたレールR上を走行する走行体2、該走行体2に設置される脚部3、該脚部3を連結する上部連結部材4、該上部連結部材4に架け渡されるように配置される平面位置調整装置5、該平面位置調整装置5に設置され、鉄筋籠Gを吊持する吊持装置15を備えている。   As shown in FIG. 1, the heavy-duty construction device 1 connects a traveling body 2 traveling on a rail R installed on the ground, a leg 3 installed on the traveling body 2, and the leg 3. The upper connecting member 4, the planar position adjusting device 5 arranged so as to be bridged over the upper connecting member 4, and the suspension device 15 that is installed in the planar position adjusting device 5 and suspends the reinforcing bar rod G are provided. .

走行体2は、走行方向の前後に配置される脚部支持架台21と、該脚部支持架台21を連結する架台連結部材22を備え、脚部支持架台21の下面にはそれぞれ、レールR上を走行するためのボックスホイール23と、走行停止時のストッパとして機能する、鉛直方向に伸縮自在なアウトリガジャッキ24が設置されている。このような構成の走行体2は、図2の平面図で示すように、走行方向と直交する方向に間隔をおいて一対が並列配置されている。なお、一対の走行体2は、鉄筋籠Gが挿入される掘削領域Tの幅より広い間隔をもって配置されることは言うまでもない。   The traveling body 2 includes a leg support pedestal 21 that is arranged before and after the traveling direction, and a gantry connecting member 22 that couples the leg support pedestal 21. A box wheel 23 for traveling the vehicle and an outrigger jack 24 that functions as a stopper at the time of traveling stop and that can extend and contract in the vertical direction are installed. As shown in the plan view of FIG. 2, a pair of traveling bodies 2 having such a configuration are arranged in parallel at intervals in a direction orthogonal to the traveling direction. In addition, it cannot be overemphasized that a pair of traveling body 2 is arrange | positioned with the space | interval wider than the width | variety of the excavation area | region T in which the reinforcing bar G is inserted.

脚部3は、図1で示すように、鉛直方向に伸縮するよう配置される油圧式ジャッキよりなり、走行体2の走行方向前後に配置される脚部支持架台21に対してシリンダ31が着脱自在に固定されている。図2で示すように、脚部3は合計4体設置されることから、例えば、油圧式ジャッキに20tの荷重を支持可能なものを採用すると、重量物建込装置1は、鉄筋籠G、上部連結部材4および平面位置調整装置5の重量を合計して80tまで支持することが可能となる。   As shown in FIG. 1, the leg portion 3 is composed of a hydraulic jack arranged so as to extend and contract in the vertical direction, and the cylinder 31 is attached to and detached from the leg portion support base 21 arranged before and after the running body 2 in the running direction. It is fixed freely. As shown in FIG. 2, since a total of four legs 3 are installed, for example, when a hydraulic jack that can support a load of 20 t is adopted, the heavy-weight building device 1 is a rebar rod G, The total weight of the upper connecting member 4 and the planar position adjusting device 5 can be supported up to 80 t.

上部連結部材4は、図1及び図3で示すように、一対の走行体2各々に設置された脚部3のうち、走行体2の走行方向と直交する方向に隣り合う該脚部3どうしを連結するよう、走行方向に間隔をおいて一対配置されている。これにより、一対の走行体2各々に設置された脚部3は、走行方向前方側に位置する脚部3どうし及び走行方向後方側に位置する脚部3どうしがそれぞれ連結される。また、上部連結部材4は、脚部3をなす油圧式ジャッキのロッド32に対して着脱自在に固定されている。   As shown in FIGS. 1 and 3, the upper connecting member 4 is formed by connecting the leg portions 3 adjacent to each other in the direction orthogonal to the traveling direction of the traveling body 2 among the leg portions 3 installed in each of the pair of traveling bodies 2. A pair is arranged at intervals in the traveling direction so as to connect the two. Thereby, the leg part 3 installed in each of a pair of traveling body 2 connects the leg part 3 located in the running direction front side, and the leg part 3 located in the running direction back side, respectively. The upper connecting member 4 is detachably fixed to a rod 32 of a hydraulic jack forming the leg portion 3.

平面位置調整装置5は、後に述べる吊持装置15の平面位置を走行体2の走行方向及び走行方向と直交する方向に微調整するための装置であり、図4で示すように、一対の上部連結部材4に架け渡されるように配置される一対の走行直交方向移動部材6、一対の走行直交方向移動部材6間に架け渡される井桁状部材7、および該井桁状部材7上に配置される走行方向移動部材8により構成される。なお、井桁状部材7は、一対の走行直交方向移動部材6どうしを連結する一対の第1桁部材71と、一対の第1桁部材71どうしを連結する一対の第2桁部材72とにより構成される。そして、走行方向移動部材8は、一対の第2桁部材72に架け渡されるように設置される。   The planar position adjusting device 5 is a device for finely adjusting the planar position of the suspension device 15 described later in the traveling direction of the traveling body 2 and the direction orthogonal to the traveling direction. As shown in FIG. A pair of traveling orthogonal direction moving members 6 arranged so as to be bridged over the connecting member 4, a cross beam-like member 7 bridged between the pair of traveling orthogonal direction moving members 6, and the cross beam-like member 7. The traveling direction moving member 8 is used. The cross-girder member 7 includes a pair of first girder members 71 that couple the pair of travel orthogonal direction moving members 6 and a pair of second girder members 72 that couple the pair of first girder members 71 to each other. Is done. The traveling direction moving member 8 is installed so as to be bridged between the pair of second girder members 72.

上述する構成の平面位置調整装置5は、一対の走行直交方向移動部材6が、図4で示すように、上部連結部材4に設けた反力板10に支持され走行方向と直交する方向に伸縮する伸縮装置9を介して、上部連結部材4上を走行方向と直交する方向に移動する。また、走行方向移動部材8が、図1及び図4で示すように、一対の走行直交方向移動部材6間に設けた反力板12に支持され走行方向に伸縮する伸縮装置11を介して、井桁状部材7をなす一対の第2桁部材72上を走行方向に移動する。そして、走行方向移動部材8には、吊持装置15が設置されることから、吊持装置15は上述する構成の平面位置調整装置5により、4体の脚部3の内側エリア内を走行方向及び走行方向と直交する方向に平面位置を移動することとなる。   In the planar position adjusting device 5 having the above-described configuration, the pair of traveling orthogonal direction moving members 6 are supported by the reaction force plate 10 provided in the upper connecting member 4 and extend and contract in a direction orthogonal to the traveling direction, as shown in FIG. The upper connecting member 4 is moved in a direction orthogonal to the traveling direction via the extending and contracting device 9. Further, as shown in FIGS. 1 and 4, the traveling direction moving member 8 is supported by a reaction force plate 12 provided between a pair of traveling orthogonal direction moving members 6, via an expansion / contraction device 11 that expands and contracts in the traveling direction. It moves on the pair of second girder members 72 forming the cross-girder member 7 in the traveling direction. Since the travel direction moving member 8 is provided with the suspension device 15, the suspension device 15 travels in the inner area of the four legs 3 by the planar position adjustment device 5 having the above-described configuration. In addition, the plane position is moved in a direction orthogonal to the traveling direction.

また、吊持装置15は、図1で示すように、鉛直方向に伸縮する伸縮装置13と、伸縮装置13に設置された吊り治具14により構成される。伸縮装置13は油圧式ジャッキによりなり、ロッド131の先端が走行方向移動部材8に連結されることで、平面位置調整装置5に対して垂下状態で設置される。そして、吊り治具14は、伸縮装置13のシリンダ132の外周に、当該シリンダ132を軸にして水平面内で回転自在に接合されている。なお、吊り治具14はいずれの形状を有するものでもよいが、本実施の形態では、シリンダ132が貫通する孔を設けた平板部材141と、該平板部材141の下面より垂下される複数のワイヤ142とにより構成している。   Further, as shown in FIG. 1, the suspension device 15 includes an expansion device 13 that expands and contracts in the vertical direction and a suspension jig 14 that is installed in the expansion device 13. The telescopic device 13 is a hydraulic jack, and is installed in a suspended state with respect to the planar position adjusting device 5 by connecting the tip of the rod 131 to the traveling direction moving member 8. The suspension jig 14 is joined to the outer periphery of the cylinder 132 of the telescopic device 13 so as to be rotatable in a horizontal plane with the cylinder 132 as an axis. The hanging jig 14 may have any shape, but in this embodiment, a flat plate member 141 provided with a hole through which the cylinder 132 passes and a plurality of wires suspended from the lower surface of the flat plate member 141. 142.

上述する構成の重量物建込装置1は、吊り治具14に備えた複数のワイヤ142を鉄筋籠Gに連結した状態で走行体2を介してレールR上を走行することにより、鉄筋籠Gを作業領域内で搬送することができる。   The heavy article building apparatus 1 having the above-described configuration travels on the rail R via the traveling body 2 in a state where the plurality of wires 142 provided in the hanging jig 14 are connected to the reinforcing bar G, so that the reinforcing bar G Can be transported in the work area.

また、重量物建込装置1は、脚部3の伸縮および吊持装置15に備えた伸縮装置13の伸縮により、鉄筋籠Gを鉛直方向に移動させることが可能となる。このとき、図1で示すように脚部3と伸縮装置13の両者を伸長した状態から、伸縮装置13のみを短縮することで、鉄筋籠Gを最も上方まで釣り上げることが可能となる。一方、図5で示すように脚部3と伸縮装置13の両者を短縮した状態から、伸縮装置13のみを伸長することで、鉄筋籠Gを最も下方まで釣り下げることが可能となる。このように、吊持装置15に備えた吊り治具14における鉛直方向の可動範囲は、脚部3の伸縮量に伸縮装置13の伸縮量が加算されるから、脚部3のみが伸縮する場合と比較して、より高さの大きい鉄筋籠Gを吊持することが可能となる。   Further, the heavy-duty construction device 1 can move the reinforcing bar rod G in the vertical direction by the expansion and contraction of the legs 3 and the expansion and contraction of the expansion and contraction device 13 provided in the suspension device 15. At this time, as shown in FIG. 1, it is possible to lift the reinforcing bar rod G to the uppermost position by shortening only the telescopic device 13 from the state where both the leg 3 and the telescopic device 13 are extended. On the other hand, as shown in FIG. 5, it is possible to hang down the reinforcing bar rod G to the lowest position by extending only the telescopic device 13 from a state where both the leg 3 and the telescopic device 13 are shortened. As described above, the vertical movable range of the suspension jig 14 provided in the suspension device 15 is obtained by adding the expansion / contraction amount of the expansion / contraction device 13 to the expansion / contraction amount of the leg portion 3, so that only the leg portion 3 expands / contracts. Compared to the above, it is possible to suspend the reinforcing bar rod G having a larger height.

さらに、重量物建込装置1は、平面位置調整装置5と吊持装置15に備えた吊り治具14により、鉄筋籠Gの平面位置を移動させることができる。つまり、鉄筋籠Gは、走行体2が停止した状態であっても、図4で示すように、平面位置調整装置5により走行体2の走行方向および走行方向と直交する方向の移動が可能である。また、伸縮装置13に対して吊り治具14を水平面内で回転させることにより、鉄筋籠Gは、伸縮装置13を中心軸とした水平回転方向にも平面移動が可能となる。   Furthermore, the heavy article building device 1 can move the planar position of the reinforcing bar rod G by the suspension jig 14 provided in the planar position adjusting device 5 and the suspension device 15. That is, as shown in FIG. 4, the reinforcing bar rod G can be moved in the traveling direction of the traveling body 2 and the direction orthogonal to the traveling direction by the planar position adjusting device 5 as shown in FIG. 4. is there. Further, by rotating the suspension jig 14 with respect to the expansion / contraction device 13 in a horizontal plane, the reinforcing bar rod G can also be moved in the horizontal direction around the expansion / contraction device 13 as a central axis.

加えて、重量物建込装置1は、脚部3を、脚部支持架台21と上部連結部材4の両者に対して着脱自在に固定していることから、脚部3として採用する油圧式ジャッキを適宜交換することが可能である。したがって、4体の脚部3について、平面視で大きく扁平した長方形とならないよう、走行体2の走行方向前後の間隔と走行方向と直交する方向に隣り合う間隔とを櫓をなすように十分取り、吊持したい鉄筋籠Gの重量に応じた油圧式ジャッキを脚部3に採用することにより、重量物建込装置1が変形することなく、安定して超重量の鉄筋籠Gを吊持することが可能となる。   In addition, since the heavy load building device 1 fixes the leg 3 to the leg support base 21 and the upper connecting member 4 in a detachable manner, the hydraulic jack employed as the leg 3 is used. Can be replaced as appropriate. Therefore, with respect to the four leg portions 3, the distance before and after the traveling direction of the traveling body 2 and the distance adjacent to each other in the direction orthogonal to the traveling direction are sufficiently set so as not to be a flattened rectangle in plan view. By adopting a hydraulic jack according to the weight of the reinforcing bar G to be hung on the leg 3, the heavy load erection device 1 can be stably suspended without deforming the heavy load building apparatus 1. It becomes possible.

次に、上記の重量物建込装置1を利用した鉄筋籠Gの建込方法を図6〜9を参照しつつ、以下に説明する。
なお、本実施の形態では、図7で示すように、地中に設けた掘削領域Tには安定液Bが充填されているとともに、既に2段の鉄筋籠G’が建て込まれてかんざし筋16にてその荷重を仮受けした状態となっている。
Next, a method for building a reinforcing bar rod G using the heavy load building device 1 will be described below with reference to FIGS.
In the present embodiment, as shown in FIG. 7, the excavation area T provided in the ground is filled with the stabilizing liquid B, and the two-stage reinforcing bar G ′ has already been built, and the hairpin At 16, the load is temporarily received.

まず、図6(a)で示すように、例えばフォークリフト等の作業車両17にて継ぎ足そうとする鉄筋籠Gを搬送し、図6(b)で示すように、掘削領域Tの近傍の仮置き場18に仮置きする。次に、図3で示すような、掘削領域Tを挟んだ両側の地表面に敷設されたレールRを利用して、図7(a)で示すように、走行体2により重量物建込装置1を仮置き場18へ移動させる。このとき、脚部3を伸長するとともに吊持装置15の伸縮装置13を短縮して、吊り治具14を最上部に配置させておくとよい。この後、図7(b)で示すように、鉄筋籠Gの高さに応じて、脚部3の短縮や吊持装置15の伸長を行い、吊り治具14に備えたワイヤ142を鉄筋籠Gの上部に連結する玉掛け作業を行う。   First, as shown in FIG. 6 (a), the reinforcing bar rod G to be added is transported by a work vehicle 17 such as a forklift, for example, and as shown in FIG. Temporary storage in the storage area 18. Next, using the rails R laid on both ground surfaces across the excavation area T as shown in FIG. 3, as shown in FIG. 1 is moved to the temporary storage 18. At this time, it is preferable to extend the leg portion 3 and shorten the telescopic device 13 of the suspension device 15 so that the suspension jig 14 is arranged at the top. Thereafter, as shown in FIG. 7B, the leg 3 is shortened or the suspension device 15 is extended according to the height of the reinforcing bar rod G, and the wire 142 provided in the hanging jig 14 is connected to the reinforcing bar rod. The slinging work connected to the upper part of G is performed.

次に、図8(a)で示すように、脚部3を伸長するとともに吊持装置15の伸縮装置13を短縮して、鉄筋籠Gを最上部まで釣り上げた状態で、図8(b)で示すように、鉄筋籠Gが掘削領域Tの直上に位置するよう重量物建込装置1を移動させた後、走行体2の下面に設置したアウトリガジャッキ24を伸長させて、重量物建込装置1を固定する。この後、継ぎ足そうとする鉄筋籠Gについて、平面位置調整装置5により走行体2の走行方向および走行方向と直交する方向へ移動させる、もしくは伸縮装置13に対して吊り治具14を水平回転させる等、平面位置を微調整することで、掘削領域Tに挿入されている鉄筋籠G’との位置出しを行う。   Next, as shown in FIG. 8 (a), the leg 3 is extended and the telescopic device 13 of the suspension device 15 is shortened so that the reinforcing bar rod G is lifted up to the top, and FIG. 8 (b). As shown in Fig. 2, after moving the heavy load construction device 1 so that the reinforcing bar G is located immediately above the excavation region T, the outrigger jack 24 installed on the lower surface of the traveling body 2 is extended to build the heavy load. The device 1 is fixed. Thereafter, the reinforcing bar G to be added is moved by the planar position adjusting device 5 in the traveling direction of the traveling body 2 and in the direction perpendicular to the traveling direction, or the suspension jig 14 is rotated horizontally with respect to the telescopic device 13. The position of the reinforcing bar rod G ′ inserted in the excavation region T is determined by finely adjusting the planar position, for example.

この状態で、図9(a)で示すように、吊持装置15の伸縮装置13を必要量だけ伸長して継ぎ足そうとする鉄筋籠Gを吊り降ろし、掘削領域Tに挿入されている鉄筋籠G’との連結作業を行う。そして、掘削領域Tに挿入されている鉄筋籠G’の荷重を仮受していたかんざし筋16を取り外し、掘削領域Tに挿入されている鉄筋籠G’とこれに継ぎ足した鉄筋籠Gの荷重の両者を、重量物建込装置1にて支持する。この後、脚部3を短縮するとともに吊持装置15の伸縮装置13を伸長して、継ぎ足した鉄筋籠Gを掘削領域T内に吊りおろし、図9(b)で示すように、継ぎ足した鉄筋籠Gおよび先行して掘削領域Tに挿入されていた鉄筋籠G’の荷重をかんざし筋16に盛り替える。   In this state, as shown in FIG. 9A, the reinforcing bar G to be added by extending the telescopic device 13 of the lifting device 15 by a necessary amount is suspended and the reinforcing bar inserted in the excavation region T is suspended. Connect with 籠 G '. Then, the barb 16 that has temporarily received the load of the reinforcing bar G ′ inserted in the excavation area T is removed, and the load of the reinforcing bar G ′ inserted in the excavation area T and the load of the reinforcing bar G added thereto Both of these are supported by the heavy article erection device 1. Thereafter, the leg portion 3 is shortened and the telescopic device 13 of the suspension device 15 is extended to suspend the added reinforcing bar rod G in the excavation region T, and the added reinforcing bar as shown in FIG. 9B. The load of the reed bar G and the rebar bar G ′ that has been inserted in the excavation area T in advance is replaced with the barb 16.

これらの作業が終了した後、継ぎ足した鉄筋籠Gとワイヤ142との連結を解除し、重量物建込装置1を移動させる。上述する作業を、所望の数量の鉄筋籠Gを連結して掘削領域Tに建て込むまで繰り返すことで、掘削領域Tへの鉄筋籠Gの建込み作業が終了する。   After these operations are completed, the connection between the reinforcing bar G and the wire 142 that have been added is released, and the heavy article construction device 1 is moved. The above-described operation is repeated until a desired number of reinforcing bar rods G are connected and built in the excavation area T, whereby the installation operation of the reinforcing bar rod G in the excavation area T is completed.

上記の鉄筋籠Gの建込方法によれば、継ぎ足そうとする鉄筋籠Gを重量物建込装置1にて掘削領域Tの直上に配置した後、鉄筋籠Gの平面位置を重量物建込装置1の移動によることなく、平面位置調整装置5と吊持装置15にて適宜微調整することができる。したがって、先行して掘削領域Tに挿入されている鉄筋籠G’に対する鉄筋籠Gの位置出しを、簡略な作業で効率よく、また精度よく行うことが可能となる。   According to the above-described method of building the reinforcing bar G, after the reinforcing bar G to be added is placed immediately above the excavation region T by the heavy load building device 1, the planar position of the reinforcing bar G is set to the heavy building. The flat position adjustment device 5 and the suspension device 15 can be finely adjusted as appropriate without moving the insertion device 1. Therefore, it is possible to efficiently and accurately position the reinforcing bar rod G relative to the reinforcing bar rod G ′ previously inserted in the excavation region T by a simple operation.

なお、本発明の重量物建込装置1は、上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲で種々の変更が可能であることはいうまでもない。   In addition, it goes without saying that the heavy article building device 1 of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

例えば、本実施の形態では、一対の走行体2どうしを直接連結していないが、走行方向前方側の脚部支持架台21どうし、もしくは走行方向後方側の脚部支持架台21どうしを連結する構成としてもよい。こうすると、4体の脚部3どうしがより強固に連結されるため、脚部3に大荷重を支持可能な油圧式ジャッキを採用し、重量物建込装置1にて超重量物を支持することが可能となる。なお、走行方向前方側および後方側の両者の脚部支持架台21どうしを連結する場合には、いずれか一方を開閉式とし、一対の走行体2の間に鉄筋籠Gを走行方向から挿入できるようにするとよい。   For example, in the present embodiment, the pair of traveling bodies 2 are not directly connected to each other, but the leg supporting bases 21 on the front side in the traveling direction or the leg supporting bases 21 on the rear side in the traveling direction are connected to each other. It is good. In this way, the four leg portions 3 are more firmly connected to each other, so that a hydraulic jack capable of supporting a large load is adopted for the leg portion 3, and the heavy load building device 1 supports the super heavy load. It becomes possible. In addition, when connecting the leg part support bases 21 of both the front side and the back side in the traveling direction, one of them can be opened and closed, and the reinforcing bar G can be inserted between the pair of traveling bodies 2 from the traveling direction. It is good to do so.

また、本実施の形態では、脚部3、平面位置調整装置5に備えた伸縮装置9および伸縮装置11、吊持装置15の伸縮装置13にそれぞれ油圧式ジャッキを採用したが、必ずしもこれに限定されるものではなく、伸縮自在に構成されたジャッキであれば機械式や空気式等いずれを採用してもよい。   Moreover, in this Embodiment, although the hydraulic jack was each employ | adopted as the expansion-contraction apparatus 9 and the expansion-contraction apparatus 11 with which the leg part 3 and the plane position adjustment apparatus 5 were equipped, and the expansion-contraction apparatus 13 of the suspension apparatus 15, it is not necessarily restricted to this. However, any mechanical type or pneumatic type may be adopted as long as the jack is configured to be stretchable.
