Description

この発明は、線路上空構造物の構築方法及びその装置に関するものであり、既設のプラットホーム上等の既設の駅構内の線路上空に人工地盤等を架設し、プロムナードや駅ビル等の構造物を新築・増築する場合などに適用される。   The present invention relates to a method for constructing a structure over a track and an apparatus therefor, in which an artificial ground or the like is installed over a track in an existing station such as an existing platform, and a structure such as a promenade or a station building is newly built.・ Applicable when expanding.

このような電車が運行している線路上空に構造物を構築する場合には、電車の運行を優先させて運行時間外に工事をしなければならないなど様々な制約を受け、特に、都市近郊の駅周辺では、搬入路に制限があり三方塞がりや四方塞がりの場所や狭隘空間での作業が珍しくなく、構造物の構成材を揚重及び搬入し、建方を行う際に問題があった。   When constructing structures over the railway lines where such trains operate, there are various restrictions, such as prioritizing train operations and having to work outside the operating hours, especially in the suburbs of cities. In the vicinity of the station, there are restrictions on the carry-in route, and it is not uncommon to work in three- and four-way-blocked places and confined spaces, and there was a problem when carrying out construction by lifting and carrying structural components.

従来、このような構造物の建方などには、タワークレーンや自走式の油圧クレーン等が用いられており、タワークレーンは、常設固定式であるため安全上電車が運行する線路にあまり近接して設置できない。そのため、ほとんど線路構外に設置せざるを得ず、実際に構造物を構築する場所とタワークレーンの設置場所とが離れてしまい、揚重物に比べて作業半径の大きい大型のクレーンを選定しなければならないため不経済であるという問題や、駅周辺の線路構内において、タワークレーンの設置に必要な組払しヤードやクレーンの組立部材の搬入路などを確保することが困難であるという問題があった。また、タワークレーンの基礎等を設計し、その申請及び許可の手続を経て基礎等を施工し、その上にタワークレーンを組立てなければならないため、計画から使用開始まで時間がかかってしまうという問題があった。   Conventionally, tower cranes, self-propelled hydraulic cranes, etc. have been used for the construction of such structures, and the tower cranes are permanently fixed, so they are very close to the tracks on which the train operates for safety reasons. Can not be installed. For this reason, it must be installed almost outside the railway track, and the place where the structure is actually built is separated from the place where the tower crane is installed, so a large crane with a larger working radius than the lifted object must be selected. There is a problem that it is uneconomical because it has to be carried out, and that it is difficult to secure a pay-in yard necessary for installing a tower crane and a carrying-in path for assembly members of the crane in the railway premises around the station. It was. In addition, it is necessary to design the foundation of the tower crane, construct the foundation etc. through the application and permission procedures, and assemble the tower crane on it, so it takes time from planning to the start of use. there were.

また、自走式の油圧クレーンでも、クローラクレーンなどの組立式のクレーンでは、前記タワークレーンと同様に、組払しヤードやクレーン部材の搬入路などを確保する必要があるし、軌陸両用のクレーンでは、駅構外の比較的スペースのある場所から線路上にクレーンを進入させ、構造物を構築する場所の近くまでクレーンを移動して、線路構内の軌道間にクレーンを設置することはできるが、その場合でも構成部材を吊り下げて建方を行う関係上、ブームの旋回範囲内のトロリー線を移設又は盛替えする工事を行わなければならないという問題や、トロリー線を盛替える場合には、そのために夜間などに行う建方工事毎に電気工事の担当者や見張り員を更に動員しなければならないという問題があった。また、クレーン設置場所には、アウトリガーをクレーン本体外側に張り出して設置地盤の反力を得る関係上、広範囲に亘って線路の覆工及びその撤去工事を行わなければならず、建方工事に時間と手間がかかってしまうという問題があった。   In addition, even in self-propelled hydraulic cranes, assembly cranes such as crawler cranes need to secure a pay-in yard and a crane member carry-in path, as in the case of the tower crane, and a crane for both road and land use. Then, it is possible to install a crane between the tracks on the track yard by moving the crane near the place where the structure is built by entering the crane from a place with relatively space outside the station premises, Even in that case, because of the construction of hanging components, the problem of having to relocate or replace the trolley wire within the swivel range of the boom, or when replacing the trolley wire, In addition, there was a problem in that it was necessary to further mobilize the person in charge of electrical work and the watchman for each construction work performed at night. In addition, in order to obtain the reaction force of the installation ground by extending the outrigger to the outside of the crane body at the crane installation site, it is necessary to carry out line lining and removal work over a wide range, and time for construction work There was a problem that it took time and effort.

このような問題を解決するべく、本出願人は、線路上空構造物の構築方法及びその装置として、鉄骨構造物の本設の1節柱を全て立設し、その一端側に構築した本設の端部架構の上で、上部構造部の適宜長さのブロックを組立てる工程と、組立てられたブロックを他端側へスライドさせる工程と、スライドしたブロックに次のブロックを組立てて接続する工程を順次繰り返し、端部架構から他端側へ迫り出した上部構造を他端側の1節柱で支承しつつスライドさせ、上部構造が所定の据え付け位置に達すると、上部構造をリフトダウンさせて上部構造の2節柱を1節柱に接合し、1節床版を正規の取付位置までリフトダウンさせて1節柱に接合する鉄骨構造物の建方工法及びその装置を既に提案している(特許文献1参照)。   In order to solve such a problem, the present applicant, as a construction method and apparatus for an over-the-rail structure, installed all the one-node pillars of the steel structure in a standing manner, and constructed the end of the construction constructed on one end side thereof. On the frame, the process of assembling an appropriate length block of the upper structural part, the process of sliding the assembled block to the other end side, and the process of assembling and connecting the next block to the slide block are sequentially repeated. The upper structure protruding from the end frame to the other end side is slid while being supported by the one-node pillar on the other end side. When the upper structure reaches a predetermined installation position, the upper structure is lifted down to We have already proposed a construction method and apparatus for a steel structure in which a 2-node column is joined to a 1-column column, and a 1-node floor slab is lifted down to a proper mounting position and joined to the 1-node column (Patent Literature). 1).

しかし、特許文献1に記載の鉄骨構造物の建方工法及びその装置であっても、1節目の柱等の線路直上の鉛直部材の建込みにおいては、従来通りタワークレーンや自走式の油圧クレーンを使用するか、軌道走行用のフォークリフトを使用するか、して工事を行う他なく、タワークレーンや自走式の油圧クレーンを使用する場合では、1節目の柱等の建方工事に関して前記従来の問題が解決されていないし、フォークリフトを使用する場合では、揚重する部材は比較的軽量な物に限られるため、構成部材を分節しなければならず不経済であるという問題や、3次元的な揚重作業ができないため、仮止めボルトの挿入や、建入れ調整などに時間がかかり、作業に手間と時間がかかってしまうという問題があった。
特開2005−036485号公報
However, even in the construction method and apparatus for steel structures described in Patent Document 1, in the conventional construction of a vertical member directly above the track such as a first column, a tower crane or a self-propelled hydraulic When using a tower crane or a self-propelled hydraulic crane, the work must be done by using a crane or a forklift for running on a track. The conventional problems have not been solved, and when using a forklift, the members to be lifted are limited to relatively light objects, so that the components must be segmented, which is uneconomical, and three-dimensional Since the lifting work cannot be performed efficiently, it takes time to insert the temporary fixing bolts and adjust the erection, and the work takes time and effort.

The outer arm 7a and the inner arm 7b are connected by an arm telescopic cylinder 27 provided in the arm, and the inner arm 7b can be expanded and contracted with respect to the outer arm 7a by operation of the cylinder.

把持装置8は、伸縮アーム7の先端、つまりインナーアーム7bの先端に軸着されると共に、インナーアーム7bに枢支された上下首振りシリンダ30でリンク31を介して連結されている。このため、把持装置8は、上下に首振り動可能となっている。この把持装置8は、左右の首振り部33と回転部34と把持部35を具えている。   The gripping device 8 is pivotally attached to the tip of the telescopic arm 7, that is, the tip of the inner arm 7b, and is connected via a link 31 by a vertical swing cylinder 30 pivotally supported by the inner arm 7b. For this reason, the gripping device 8 can swing up and down. The gripping device 8 includes left and right swinging portions 33, a rotating portion 34, and a gripping portion 35.

左右首振り部33は、ブラケット37にピン38を中心として左右に揺動自在に取付けたブラケット39と、これらのブラケット37,39の左右に取付けた一対の左右揺動シリンダ41,42とにより構成され、左右揺動シリンダ41,42の一方を伸長させると同時に他方を収縮させることにより、ブラケット39を左右に揺動・首振りさせるものである。   The left / right swinging portion 33 includes a bracket 39 attached to the bracket 37 so as to be able to swing left and right around a pin 38, and a pair of left and right swing cylinders 41, 42 attached to the left and right of the brackets 37, 39. Then, by extending one of the left and right swing cylinders 41 and 42 and simultaneously contracting the other, the bracket 39 swings and swings left and right.

回転部34は、ブラケット39に取付けた外輪44と、この外輪44の内周に旋回自在に取付けられるとともに内歯歯車を有する内輪(図示せず)と、ブラケット39に取付けた回転モータ46と、この回転モータ46の出力軸に取付けられ、内輪の内歯歯車と噛合するピニオン(図示せず)と、この内輪に固定された旋回フレーム47とからなっている。   The rotating part 34 includes an outer ring 44 attached to the bracket 39, an inner ring (not shown) which is rotatably attached to the inner periphery of the outer ring 44 and has an internal gear, a rotation motor 46 attached to the bracket 39, A pinion (not shown) is attached to the output shaft of the rotary motor 46 and meshes with the internal gear of the inner ring, and a turning frame 47 fixed to the inner ring.

把持部35は、旋回フレーム47の両側に固定して取付けた側板48と、各側板48の下部にそれぞれ取付けた固定爪49と、リンク機構50を介して各側板48の頂部に取付けられた可動爪51と、可動爪51の開閉用把持シリンダ52とにより構成されている。そして、把持シリンダ52を作動することにより固定爪49と可動爪51で構造物の構成部材を1つずつ掴むことができるようになっている。リンク機構50は、各側板48にそれぞれピン54,55により回動自在に取付けられたリンク56,57と、各リンク56,57の先端にピン58,59により回動自在に連結されている。また、固定爪49と可動爪51には、角形材把持用の欠き込み61が設けられていると共に、把持用治具であるH鋼用のアダプタ63が装着可能となっている。このため、鉄骨の柱と梁のどちらも確実に把持することができる。このアダプタ63を把持する構成部材の種類に応じたものとすれば、構成部材の種類にかかわらず確実に把持することができる。   The grip portion 35 is fixedly attached to both sides of the revolving frame 47, a fixed plate 49 attached to the lower portion of each side plate 48, and a movable portion attached to the top of each side plate 48 via a link mechanism 50. The claw 51 and the opening / closing gripping cylinder 52 of the movable claw 51 are configured. Then, by operating the gripping cylinder 52, the structural members of the structure can be gripped one by one by the fixed pawl 49 and the movable pawl 51. The link mechanism 50 is rotatably connected to the side plates 48 by pins 54 and 55, and is rotatably connected to the tips of the links 56 and 57 by pins 58 and 59, respectively.

Yes.

前記に説明した作業車1及び軌陸走行車2を用いて構造物の構築する方法を説明する。先ず、作業車1の設置工程を説明する。前述のように、作業車1は軌道走行装置12を使用することにより線路上も走行できるので、線路が密集していて作業車1を荷降ろしする場所がとりにくい駅構内などではなく、駅から少し離れたような比較的スペースのある場所から作業車1をキャタピラ装置13が線路を跨ぐように位置させる。しかる後、軌道走行装置12を図5に示すようにキャタピラ装置13より下方に突出するように起立させて線路上に載せる。このようにして作業車1を線路上に進入させ、そこから軌道走行装置12により所定位置まで自走させ、所定位置に到達したところで停止させる。   A method for constructing a structure using the work vehicle 1 and the track running vehicle 2 described above will be described. First, the installation process of the work vehicle 1 will be described. As described above, since the work vehicle 1 can travel on the track by using the track traveling device 12, the work vehicle 1 is not located in the station premises where the track is dense and the work vehicle 1 is difficult to unload. The work vehicle 1 is positioned so that the caterpillar device 13 straddles the track from a place with a relatively large space such as a little away. Thereafter, the track traveling device 12 is erected so as to protrude downward from the caterpillar device 13 as shown in FIG. In this way, the work vehicle 1 enters the track, and from there, the track traveling device 12 self-travels to a predetermined position, and stops when it reaches the predetermined position.

そして、作業車1が所定位置に停止すると、キャタピラ装置13を図2の矢印方向に突出させると共に、軌道走行装置12を倒伏させて線路から上方に離すようにする。これにより作業車1はキャタピラ装置13が図のように地上に接地するので、その接地状態で据え付け固定する。尚、図2等に示すように、予め線路覆工の工事を行い、接地面であるキャタピラ装置13の下方に、枕木、端太角などを敷き詰め養生すれば、揚重時に均等な反力を得易く旋回動作などに対して安全であり、また、工事中に線路廻りを傷めることがないので好ましい。   When the work vehicle 1 stops at a predetermined position, the caterpillar device 13 is protruded in the direction of the arrow in FIG. 2 and the track traveling device 12 is laid down and separated upward from the track. As a result, the caterpillar device 13 is grounded to the ground as shown in the figure, so that the work vehicle 1 is installed and fixed in the grounded state. In addition, as shown in FIG. 2 etc., if the work of line lining is performed in advance, and sleepers, thick corners, etc. are spread and cured under the caterpillar device 13 which is the ground contact surface, a uniform reaction force will be generated during lifting. It is preferable because it is easy to obtain and safe against turning operation and the like and does not damage the track.

次に、構造物の構成部材の搬入工程を説明する。鉄骨柱Cなどの構成部材を製作工場などで軌陸台車2に積載する。そして、軌陸台車2も作業車1と同様に、駅構外の比較的スペースのある場所から軌陸台車2を作業車1が走行する線路と隣接する線路上に進入させるとともに、そこから作業車1の設置位置近くの所定位置まで走行させ、所定位置に到達したところで停止させる。そして、軌陸台車2が所定位置に停止すると、図1に示すように軌道走行装置12を倒伏させて線路から上方に離すようにする。これにより軌陸台車2が図のようにタイヤで地上に接地するので、その接地状態で据え付け固定する。尚、電車の運行時には、送電所から、饋電線などを介してトロリー線に通電し、パンタグラフなどを介して電車に送電している。この饋電線への通電を停止又は開始するには、それぞれ30分程度の時間を要し、首都圏のように電車運行停止時間が3時間程度しかない地域で工事を行う際には、饋電線への通電停止又は開始にかかる時間ロスが問題となっている。しかし、建方工事の準備段階にあたるここまでの工程は、後で詳述するが、饋電線に送電される電気を止めずに行うことができる。   Next, the carrying-in process of the structural member of a structure is demonstrated. A structural member such as a steel column C is loaded on the rail car 2 at a production factory or the like. As with the work vehicle 1, the gauge land carriage 2 also enters the gauge land carriage 2 on a track adjacent to the track on which the work vehicle 1 travels from a place with a relatively large space outside the station, and from there, the work vehicle 1 The vehicle travels to a predetermined position near the installation position and stops when it reaches the predetermined position. When the track carriage 2 stops at a predetermined position, the track traveling device 12 is laid down and separated upward from the track as shown in FIG. As a result, the track carriage 2 is grounded with tires as shown in the figure, and is installed and fixed in the grounded state. During train operation, the trolley line is energized from the power transmission station via a feeder and the like, and is transmitted to the train via a pantograph or the like. It takes about 30 minutes each to stop or start energization of this feeder, and when working in an area where the train stoppage time is only about 3 hours like the metropolitan area, There is a problem of loss of time required to stop or start energization. However, the process so far, which is the preparation stage of the construction work, can be performed without stopping the electricity transmitted to the feeder, as will be described in detail later.

次に、構造物の構成部材の搬入後、取付けまでの工程を図6に示す作用図も参照して説明する。図1中に示す(1)は、構造物の構成部材の揚重工程を示しており、作業車1の把持装置8の把持シリンダ52を作動して鉄骨柱Cを把持部35の固定爪49と可動爪51で直接把持し掴む。そして、マストシリンダ20を作動してマスト16の外筒16aを上方にスライドさせ、アーム起伏シリンダ26を作動して伸縮アーム7を起こすと共に、上下首振りシリンダ30を作動して把持部35を首振り動作させて揚重する。(2)は、構成部材を取付ける位置の直上まで移動する移動工程を示しており、鉄骨柱Cを固定爪49と可動爪51で略水平に把持したまま、上部旋回体6を旋回することにより鉄骨柱Cを水平移動させて移動する。このように、トロリー線の下にある揚重場所からトロリー線の下方を通過させて運ぶことができるので、背景技術で述べたように、クレーン等で鉄骨を吊り下げて移動させる場合と違って、トロリー線を移設したり、盛替えしたりする必要がない。(3)は、構成部材の取付け工程を示し、鉄骨柱Cを把持した状態で回転部34の回転モータ46を作動して把持部35を回転させ、鉄骨柱Cの向きを水平方向から所定の向きである鉛直方向に変え(縦方向部材は縦方向に変え、横方向部材はそのまま横方向)、アーム伸縮シリンダ27を作動して伸縮アーム7を伸縮させたり、回転モータ46を作動して把持部35を回転させたり、あるいは上下首振りシリンダ30や左右揺動シリンダ41,42を作動して左右首振り部33を首振り動作させて所定位置に予め設置してある基礎杭上に構成部材の鉛直調整(縦方向調整)や水平調整(横方向調整)などを行いながら建て付け、ボルトなどで固定する。   Next, the steps from the loading of the structural members to the mounting will be described with reference to the operation diagram shown in FIG. (1) shown in FIG. 1 shows a lifting process of structural members of the structure. The gripping cylinder 52 of the gripping device 8 of the work vehicle 1 is operated to fix the steel column C to the fixing claw 49 of the gripping portion 35. Grip directly with the movable claw 51. Then, the mast cylinder 20 is actuated to slide the outer cylinder 16a of the mast 16 upward, the arm hoisting cylinder 26 is actuated to raise the telescopic arm 7, and the vertical swing cylinder 30 is actuated to actuate the grip 35. Shake and lift. (2) shows a moving process in which the component member is moved to a position just above the position where the component member is attached. By turning the upper swing body 6 while holding the steel column C substantially horizontally by the fixed claw 49 and the movable claw 51, The steel column C is moved horizontally. In this way, since it can be carried from the lifting place under the trolley line through the bottom of the trolley line, as described in the background art, unlike the case where the steel frame is suspended and moved by a crane etc. There is no need to relocate or replace the trolley wire. (3) shows a mounting process of the constituent members. In a state where the steel column C is gripped, the rotary motor 46 of the rotating unit 34 is operated to rotate the gripping portion 35, and the direction of the steel column C is changed from the horizontal direction to a predetermined direction. Change to the vertical direction (vertical member changes to vertical direction, horizontal member changes to horizontal direction), and the arm telescopic cylinder 27 is operated to expand and contract the telescopic arm 7 or the rotary motor 46 is operated to grip. Rotating the part 35 or operating the up and down swing cylinder 30 and the left and right swing cylinders 41 and 42 to swing the left and right swing part 33 to constitute a component on a foundation pile previously set at a predetermined position Installed with vertical adjustment (vertical adjustment) and horizontal adjustment (horizontal adjustment), and fixed with bolts.

以上のようにして、1節目の鉄骨柱Cを立設して既設の基礎杭と接合するが、必要により前記と同様に(1)〜(3)の工程を所定回繰り返し、構造物の縦方向部材である1節目の柱を建て付ける。しかる後、横方向部材である1節目の梁を建て付けた柱間に架け渡していくように積層工法で構造物を構築していく。あるいは、2本の柱を建て付け、その間の梁を掛け渡していくことを繰り返すように建て逃げ工法や屏風建て工法などで構築していってもよく、縦方向部材と横方向部材を設置していく順番は任意である。図6は前記のような作業によりホーム間にわたり基礎杭上に1節目の柱を建て、その上に1節目の梁を建てた例を示している。   As described above, the steel column C of the first node is erected and joined to the existing foundation pile. If necessary, the steps (1) to (3) are repeated a predetermined number of times in the same manner as described above to The pillar of the 1st node which is a direction member is built. After that, a structure is constructed by a laminating method so that it is bridged between the pillars where the first joint beam, which is a transverse member, is built. Alternatively, it may be constructed by a built-in escape construction method or folding screen construction method so that two pillars are built and a beam is passed between them, and a longitudinal member and a transverse member are installed. The order of going is arbitrary. FIG. 6 shows an example in which the first node pillar is built on the foundation pile across the platforms by the above-described work, and the first node beam is built thereon.

また、1節目の梁より上方の構造物の構築は、背景技術で述べた特許文献1に記載の鉄骨構造物の建方工法で行っても構わない。   In addition, the construction of the structure above the first-node beam may be performed by the steel structure construction method described in Patent Document 1 described in the background art.

そして、重量や長さの関係上1本の柱などの構成部材を分節し、例えば、1節目の柱を分節して0節と1節とに分け、0節目の柱を建て付けその上に続けて1節目の柱を建て付けるように構築してもよく、構造物の構成部材の建て付け順番にかかわらず、(1)〜(3)の工程を繰り返して構造物を構築していけばよい。   Then, the components such as one column are segmented due to the weight and length, for example, the first column is segmented into 0 and 1 sections, and the 0th column is built on Continuing to build the first pillar, you can build the structure by repeating steps (1) to (3) regardless of the building order of the structural components. Good.

前記のような構造物の構築方法において、作業車1は、図5で示すように、アーム7が倒伏した状態での全高がトロリー線の下方1.2m以下にされているため、饋電線への通電停止作業中であっても、作業車1を線路上に進入させ、所定の建方位置の近くまで走行させて、そこに設置するまでの作業をきわめて容易に行うことができ、電車の運行停止時間が限られたなかでの作業でも時間ロスを少なく作業をすることができる。また、作業車1は、図2で示すように、上部旋回体6の下面がホーム床面の高さより高くされているため、旋回するときにホームと干渉する恐れがなく安全であり、操作者や見張り員が後方を確認する必要がなく作業手間や作業時間を短縮することができる。   In the construction method of the structure as described above, the work vehicle 1 has a total height of 1.2 m or less below the trolley wire when the arm 7 is lying down as shown in FIG. Even when the current stop operation is in progress, the work vehicle 1 can be made to enter the track, travel to the vicinity of a predetermined construction position, and the work to be installed there can be performed very easily. Even work with limited operation stop time can be done with little time loss. Further, as shown in FIG. 2, the work vehicle 1 has a lower surface of the upper swing body 6 that is higher than the height of the home floor surface. This eliminates the need for the watchman to check the back and saves work and time.

以上のように説明した、この発明の一実施の形態に係る構造物の構築において使用する部材としての作業車1や軌陸台車2は、あくまでも好適な構成を示したものであって、実施に際しては、特許請求の範囲に記載した範囲内でその構成を適宜任意に変更、修正することができる。また、前記の実施の形態では軌陸台車2を隣接する線路上を走行して線路間で接近するようにしたが、ほかに同一の線路上を走行して走行方向前後に接近するようにしてもよい。さらに、線路上空に構築される構造物やその構成部材も一例を示し、必ずしも図示のものに限定されない。   As described above, the work vehicle 1 and the rail vehicle 2 as members used in the construction of the structure according to the embodiment of the present invention show a preferable configuration to the last. The configuration can be arbitrarily changed and modified as appropriate within the scope of the claims. In the above-described embodiment, the track carriage 2 is run on adjacent tracks so as to be close to each other. However, it is also possible to run on the same track and approach the front and rear in the running direction. Good. Furthermore, the structure constructed over the track and its constituent members are also examples, and are not necessarily limited to those illustrated.
