I will provide a. SOLUTION: A heavy load transport structure TR includes a support member 5 that detachably connects a temporary rail 2 and a hoisting machine 4. Since the hoisting machine is integrated with the temporary rail through the supporting material, the force generated when the wire 3 is wound up by the hoisting machine after the trolley 1 carrying a heavy load has been on the temporary rail for a while. Since the (pulling force between the carriage and the hoisting machine) is offset by the force compressing the supporting material 5, the hoisting machine, the supporting material, and the temporary rail are moved toward the heavy object by the reaction force of the winding. Therefore, it is not dragged.Therefore, a hole is made in a part of the existing building at the site for transporting heavy goods, and anchors are fixed to the hole to fix the hoisting machine, or members other than the hoisting machine are similarly fixed.

Description

本発明は、階段の上下フロア面を結ぶ経路等に沿って重量物を搬送する際に利用される重量物搬送構造に関し、特に、既設建物の構造にダメージを与えることなく重量物を搬送することができ、かつ、重量物の設置に要する工事期間の短縮と工事費用の低減を図るのに好適なものである。   The present invention relates to a heavy load transport structure used when transporting a heavy load along a route connecting upper and lower floor surfaces of stairs, and particularly to transporting a heavy load without damaging the structure of an existing building. In addition, it is suitable for shortening the construction period required for installing heavy objects and reducing the construction cost.

従来、エスカレータ、自動販売機等の重量物を例えば駅の2階フロアに設置する場合には、その重量物を階段に沿って搬送しなければならない。このような階段における重量物の搬送構造は、例えば特許文献1に開示されている。   Conventionally, when a heavy object such as an escalator or a vending machine is installed on the second floor of a station, for example, the heavy object must be transported along stairs. Such a heavy object transport structure on a staircase is disclosed in Patent Document 1, for example.

特許文献1の重量物搬送構造(以下「従来の重量物搬送構造」という)は、階段(R)に仮設レール(R)を2本設置し、これらの仮設レール(R)を支持する支持柱(3)間をアングル鋼材(46)で固定した構造になっている(同文献1の段落[0031]の記載と同文献1の図1を参照)。   The heavy load transport structure of Patent Document 1 (hereinafter referred to as “conventional heavy load transport structure”) has two temporary rails (R) installed on a stair (R), and a support column that supports these temporary rails (R). (3) has a structure in which an angle steel material (46) is fixed between the portions (see paragraph [0031] of the document 1 and FIG. 1 of the document 1).

また、従来の重量物搬送構造を利用して階段(J)下のフロア面(F1)から階段(J)上のフロア面(F2)へ重量物を搬送する場合は、階段下(J)のフロア面(F2)において重量物を台車(A)に乗せ、その台車(A)の車輪(1A)を2本の仮設レール(R)上に導いた後、階段(J)上のフロア面(F2)に向って当該台車Aを引き上げている(同文献1の段落[0032]の記載と同文献1の図1を参照)。   In addition, when a conventional heavy load transport structure is used to transport a heavy load from the floor surface (F1) below the stairs (J) to the floor surface (F2) above the stairs (J), After placing a heavy object on the truck (A) on the floor surface (F2) and guiding the wheels (1A) of the truck (A) onto the two temporary rails (R), the floor surface on the stairs (J) ( The trolley A is pulled up toward F2) (see paragraph [0032] of Document 1 and FIG. 1 of Document 1).

以上の説明において、カッコ内の符号は特許文献1で用いられている符号である。   In the above description, the reference numerals in parentheses are the reference numerals used in Patent Document 1.

しかしながら、従来の重量物搬送構造では、台車を引き上げる手段としてウインチ等の巻上機を用いており、この巻上機と台車をワイヤーで連結し、該ワイヤーを巻上機で巻き取ることによって台車Aを引き上げている。その際、巻取りの反力によって巻上機が台車の方向に引きずられないようにする手段として、重量物の搬送現場における既設建物の一部(例えば、柱、梁、床、天井あるいは壁)に穴を開け、その穴にアンカーを打って巻上機を固定する必要があるため、下記(1−1)から(1−5)のような問題点を有している。   However, in the conventional heavy load carrying structure, a hoisting machine such as a winch is used as a means for lifting the bogie, and the hoisting machine and the bogie are connected by a wire, and the wire is wound by the hoisting machine. A is raised. At that time, as a means to prevent the hoisting machine from being dragged in the direction of the trolley due to the reaction force of the winding, a part of the existing building (for example, a pillar, a beam, a floor, a ceiling or a wall) at the transportation site for heavy goods. Since it is necessary to make a hole in the hole and hit the anchor in the hole to fix the hoisting machine, the following problems (1-1) to (1-5) occur.

(1−1)穴開け工事によって既設建物の構造自体にダメージを与えるおそれがある。
(1−2)穴開け工事時やアンカー打ち工事時に、騒音や粉塵が発生する。
(1−3)穴開け工事だけでなく、その穴開け工事で開けた穴を後で埋める補修作業も必要になるため、重量物の設置に要する工事期間が長くなり、その工事費用も高くならざるを得ない。
(1−4)巻上機は前述の通りアンカーで固定されているので、工事期間中は巻上機を容易に取り除くことができない。このため、巻上機付近は工事関係者以外の立入を終日禁止する必要があり、禁止区域内の施設はその営業を停止せざるを得ない等、工事現場付近の施設の営業に支障が生じ得る。
(1−5)アンカーや他の方法でも巻上機を固定できない現場では、重量物の搬送が不可能になる。
(1-1) There is a risk that the structure itself of the existing building may be damaged by the drilling work.
(1-2) Noise and dust are generated during drilling work and anchoring work.
(1-3) Not only the drilling work, but also the repair work to fill the holes drilled by the drilling work later, the construction period required to install heavy objects will be long and the construction cost will be high. I have no choice.
(1-4) Since the hoisting machine is fixed by the anchors as described above, the hoisting machine cannot be easily removed during the construction period. For this reason, it is necessary to prohibit access to the hoisting machine except for construction personnel all day long, and the facilities in the prohibited area have to stop their business. obtain.
(1-5) It is impossible to carry heavy objects at a site where the hoist cannot be fixed by anchors or other methods.

A trolley for loading objects, a temporary rail for traveling the trolley, a hoisting machine connected to the trolley via a wire, and a supporting material for detachably connecting the temporary rail and the hoisting machine, The temporary rail is installed along a path connecting the upper and lower floor surfaces of the stairs, a path connecting the upper and lower sides of the step, or a path overcoming the obstacle, and connecting the temporary rail and the supporting member. Is a structure via a first connecting member, and the connection between the temporary rail and the hoisting machine is a structure via a second connecting member, and the first connecting member is a first connecting member. The temporary rail by fastening means The second connection has a temporary rail mounting portion to which one end is detachably attached, and a first supporting material attachment portion to which one end of the supporting material is detachably attached by second fastening means. The member includes a second support member attachment portion to which the other end portion of the support member is detachably attached by third fastening means, and a hoisting machine to which the hoisting machine is detachably attached by fourth fastening means. possess a mounting portion, the the upper surface of the first connecting member recess is formed, the structure of which one end portion of the temporary rail is fitted into the recess, and, at one end of the temporary rail its temporary rails A pair of blades protruding in the left-right direction is provided, and the pair of blades is fixed to the outer peripheral edge of the recess by the first fastening means. To do.

前記本発明において、前記第1の連結部材との接触による前記ワイヤーの擦れを防止する手段として、前記第1の連結部材の上面にローラが設けられ、このローラの外周面に対して前記ワイヤーが当接し、かつ、前記ワイヤーと前記ローラとの摩擦力によって前記ローラが回転するように構成したことを特徴としてもよい。   In the present invention, a roller is provided on the upper surface of the first connecting member as means for preventing rubbing of the wire due to contact with the first connecting member, and the wire is provided on the outer peripheral surface of the roller. The roller may be rotated by the contact force and the frictional force between the wire and the roller.

前記本発明において、前記仮設レールは、複数のレール片を一列に着脱自在に繋ぎ合わせた構造になっていることを特徴としてもよい。   In the present invention, the temporary rail may have a structure in which a plurality of rail pieces are detachably connected in a row.

本発明では、重量物搬送構造として、前述の通り、支保材によって仮設レールと巻上機とが連結される構造を採用した。このため、巻上機は支保材を介して仮設レールと一体化しているので、重量物を積載した台車が仮設レール上に少しでも乗っかった後は、巻上機でのワイヤーの巻取り時に生じる力、すなわち、台車と巻上機との間で引き合う力は支保材を圧縮する力となって相殺されるから、巻取りの反力によって巻上機、支保材、仮設レールが重量物の方向に引きずられることはない。従って、重量物の搬送現場における既設建物の一部(例えば、柱、梁、床、天井あるいは壁)に穴を開け、その穴にアンカーを打って巻上機を固定したり、巻上機以外の部材(例えば仮設レール、支保材)を同様に固定したりする必要がないことから、下記(2−1)から(2−5)のような作用効果が奏し得られる重量物搬送構造を提供し得る。   In the present invention, as the heavy load carrying structure, as described above, the structure in which the temporary rail and the hoisting machine are connected by the supporting material is adopted. For this reason, the hoisting machine is integrated with the temporary rail via the supporting material, so that it occurs when the wire is wound up by the hoisting machine after the trolley carrying heavy objects has been on the temporary rail for a while. The force, that is, the force of attraction between the bogie and the hoisting machine, is offset by the force of compressing the supporting material, so that the hoisting machine, the supporting material, and the temporary rail cause the hoisting machine to move in the direction of the heavy object. You won't be dragged by. Therefore, make a hole in a part of an existing building (for example, a pillar, a beam, a floor, a ceiling, or a wall) at the transport site for heavy goods, and anchor the hoist with an anchor in the hole, or other than the hoist. Since it is not necessary to similarly fix the members (for example, temporary rails and supporting members) of the above, it is possible to provide a heavy load carrying structure that can achieve the following operational effects (2-1) to (2-5). You can

(2−1)穴開け工事によって既設建物の構造自体にダメージを与えるおそれがない。
(2−2)穴開け工事やアンカー打ち工事のような騒音や粉塵が発生することもない。
(2−3)穴開け工事だけでなく、その穴開け工事で開けた穴を後で埋める補修作業も不要であり、重量物の設置に要する工事期間の短縮と、工事費用の低減を図れる。
(2−4)重量物搬送現場では、手間と時間を要する穴開け工事やアンカー打ち工事を必要とせず、仮設レールと巻上機を支保材で連結する組立・設置作業とその連結を解除する解体・撤去作業を行うだけでよく、そのような組立・設置から解体・撤去に要する時間と重量物の搬送に要する時間は合計で約30分から1時間程度で済むから、重量物搬送現場付近の施設の営業に支障が生じることは殆どない。重量物搬送現場が例えば既設駅であるとしたら、その既設駅の階段における重量物の搬送は終電から始発までの間の短時間に行うことができ、既設駅や駅利用者に迷惑をかけることもない。
(2−5)巻上機はアンカーで固定しなくてもよいので、アンカーや他の方法でも巻上機を固定できない現場でも、重量物の搬送が可能である。
(2-1) There is no possibility of damaging the structure of the existing building by the drilling work.
(2-2) No noise or dust is generated unlike the drilling work and anchoring work.
(2-3) Not only the drilling work, but also the repair work for filling the holes drilled by the drilling work later is not necessary, and the construction period required for installing heavy objects can be shortened and the construction cost can be reduced.
(2-4) At the heavy load transportation site, the assembly / installation work for connecting the temporary rail and the hoisting machine with the support material and the connection are released without the need for the time-consuming and time-consuming drilling work and anchor striking work. Only dismantling / removing work is required, and the time required for dismantling / removing from such assembly / installation and the time required for carrying heavy objects is about 30 minutes to 1 hour in total. There is almost no obstacle to the operation of the facility. If the heavy goods transport site is, for example, an existing station, the heavy goods can be transported on the stairs of the existing station in a short time from the last train to the first train, which may cause trouble to existing stations and station users. Nor.
(2-5) Since the hoist does not have to be fixed with an anchor, it is possible to carry heavy goods even at a site where the hoist cannot be fixed with an anchor or another method.

《重量物搬送構造の概要》
図1および図2を参照すると、図1の重量物搬送構造TRは、階段S1の上下フロア面F1、F2を結ぶ経路R1に沿って重量物HO(図3、図4を参照)を搬送する構造であって、重量物HOを積載する台車1(図3、図4を参照)と、台車1を走行させる仮設レール2と、台車1にワイヤー3を介して連結される巻上機4と、仮設レール2と巻上機4とを着脱自在に連結する支保材5と、を備えている。
<< Outline of heavy goods transport structure >>
Referring to FIGS. 1 and 2, the heavy load transport structure TR of FIG. 1 transports a heavy load HO (see FIGS. 3 and 4) along a route R1 connecting upper and lower floor surfaces F1 and F2 of a staircase S1. A truck 1 having a structure (see FIGS. 3 and 4) for loading a heavy load HO, a temporary rail 2 for traveling the truck 1, and a hoisting machine 4 connected to the truck 1 via a wire 3. A supporting member 5 that detachably connects the temporary rail 2 and the hoisting machine 4 is provided.

《仮設レール2の詳細》
仮設レール2は、階段S1の上下フロア面F1、F2を結ぶ経路R1に沿って設置されており、仮設レール2と支保材5との連結は、第1の連結部材6を介する構造、および、仮設レール2と巻上機4との連結は、第2の連結部材7を介する構造になっている。仮設レール2の具体的な配置構成例として、図1の重量物搬送構造TRでは、2本の仮設レール2を並列に配置している。
<< Details of Temporary Rail 2 >>
The temporary rail 2 is installed along a route R1 that connects the upper and lower floor surfaces F1 and F2 of the stairs S1, and the temporary rail 2 and the supporting member 5 are connected to each other via the first connecting member 6, and The temporary rail 2 and the hoisting machine 4 are connected to each other via a second connecting member 7. As a concrete example of the arrangement of the temporary rails 2, in the heavy goods transport structure TR of FIG. 1, two temporary rails 2 are arranged in parallel.

仮設レール2の具体的な構造例として、図1の重量物搬送構造TRでは、仮設レール2は、図示しない取付け金具で複数のレール片20を一列に着脱自在に繋ぎ合わせた構造になっている。したがって、図示しない取付け金具の取り外しによって仮設レール2はそれより長さの短い複数のレール片20に分解できる。   As a specific structural example of the temporary rail 2, in the heavy goods transport structure TR of FIG. 1, the temporary rail 2 has a structure in which a plurality of rail pieces 20 are detachably connected in a row by a mounting bracket (not shown). . Therefore, the temporary rail 2 can be disassembled into a plurality of rail pieces 20 having a shorter length by removing a mounting member (not shown).

仮設レール2の全長に比べてレール片20の全長は短いので、重量物搬送現場へのレール片の持ち込みは容易であり、取扱い性の悪い長い仮設レール2を当該現場に持ち込む必要はない。   Since the total length of the rail piece 20 is shorter than the total length of the temporary rail 2, it is easy to bring the rail piece to the heavy goods transport site, and it is not necessary to bring the long temporary rail 2 with poor handleability to the site.

仮設レール2の具体的な設置例として、図1の重量物搬送構造TRでは、経路R1に沿って所定の間隔で支持柱21(図2参照)を立て、立てた支持柱21の先端部に図示しない取付け金具を介して仮設レール(具体的にはレール片20)が取付けられる構成を採用している。したがって、取付け金具の取り外しによって仮設レールと支持柱21は分解できる。   As a specific installation example of the temporary rail 2, in the heavy goods transport structure TR of FIG. 1, the support columns 21 (see FIG. 2) are erected at predetermined intervals along the route R1, and the support columns 21 are provided at the tip end portions of the erected support columns 21. A configuration is adopted in which a temporary rail (specifically, the rail piece 20) is attached via an attachment fitting (not shown). Therefore, the temporary rail and the support column 21 can be disassembled by removing the mounting bracket.

《支保材5の詳細》
図5を参照すると、支保材5はその両端にジョイントJ1、J2を有している。このジョイントJ1、J2は、一の支保材5(5A)に対して直列に他の支保材5(5B)を連結したり、第1の連結部材6に対して支保材5(5A)を連結したりする手段として機能する。
<< Details of Support Material 5 >>
Referring to FIG. 5, the supporting member 5 has joints J1 and J2 at both ends thereof. These joints J1 and J2 connect one supporting member 5 (5A) to another supporting member 5 (5B) in series, or connect the supporting member 5 (5A) to the first connecting member 6. Function as a means to do.

ジョイントJ1、J2の具体的な構造として、図1の重量物搬送構造TRでは、図5に示したように支保材5の端部にボルト挿入穴H付きの接合板Dを設けている。   As a concrete structure of the joints J1 and J2, in the heavy goods transport structure TR of FIG. 1, as shown in FIG. 5, a joining plate D with a bolt insertion hole H is provided at the end of the supporting member 5.

一の支保材5(5A)に対して直列に他の支保材5(5B)を連結する場合は、それぞれの支保材5(5A、5B)の接合板Dどうしを対向させる。そして、その対向状態において双方のボルト挿入穴Hにボルトを通してナットで接合板Dどうしを強く締め付け固定すれば、2本の支保材5(5A、5B)連結は完了する。第1の連結部材6に対して支保材5(5A)を連結する場合も後述の通り同様である。   When connecting another supporting member 5 (5B) in series to one supporting member 5 (5A), the joining plates D of the respective supporting members 5 (5A, 5B) are opposed to each other. Then, in the opposite state, the bolts are passed through both bolt insertion holes H, and the joining plates D are strongly tightened and fixed with the nuts, whereby the connection of the two supporting members 5 (5A, 5B) is completed. The same applies to the case where the supporting member 5 (5A) is connected to the first connecting member 6 as described later.

支保材5の具体的な構造例として、図1の重量物搬送構造TRでは、四角柱の支保材を採用しているが、これに限定されることはない。   As a specific structural example of the supporting member 5, the heavy-weight carrying structure TR of FIG. 1 employs a quadrangular supporting member, but the supporting member 5 is not limited to this.

《第1の連結部材6の詳細》
第1の連結部材6は、第1の締結手段B1(図1の例ではボルトとナット)によって仮設レール2の一端部2Aが着脱自在に取付けられる仮設レール取付け部61と、第2の締結手段B2(図1の例ではボルトとナット)によって支保材5の一端部が着脱自在に取付けられる第1の支保材取付け部62と、を有している。
<< Details of the first connecting member 6 >>
The first connecting member 6 includes a temporary rail mounting portion 61 to which one end portion 2A of the temporary rail 2 is detachably mounted by a first fastening means B1 (bolts and nuts in the example of FIG. 1), and a second fastening means. B2 (bolts and nuts in the example of FIG. 1) has a first supporting member attaching portion 62 to which one end of the supporting member 5 is detachably attached.

仮設レール取付け部61の具体的な構造例として、図1の重量物搬送構造TRでは、図6に示したように、第1の連結部材6の上面に凹部61Aを形成し、この凹部61Aに仮設レール2の一端部2Aが嵌め込まれる構造、および、仮設レール2の一端部2Aにはその仮設レール左右方向に飛び出た形状になっている一対の羽根21、21が設けられ、この一対の羽根21、21が凹部61Aの外周縁部に対して第1の締結手段B1(図1の例ではボルトとナット)で固定される構造を採用しているが、この構造に限定されることはない。   As a specific structural example of the temporary rail mounting portion 61, in the heavy goods transport structure TR of FIG. 1, as shown in FIG. 6, a recess 61A is formed on the upper surface of the first connecting member 6, and the recess 61A is formed in the recess 61A. The structure in which one end 2A of the temporary rail 2 is fitted, and the one end 2A of the temporary rail 2 is provided with a pair of blades 21 and 21 having a shape protruding in the left-right direction of the temporary rail. Although a structure in which the first and second fastening means B1 (bolts and nuts in the example of FIG. 1) are fixed to the outer peripheral edge of the recess 61A is adopted, the structure is not limited to this structure. .

第1の支保材取付け部62の具体的な構造例として、図1の重量物搬送構造TRにおいては、前述のジョイントJ1、J2と同じ構造のジョイントJ3(図5参照)を採用している。   As a specific structural example of the first support member mounting portion 62, in the heavy load transport structure TR of FIG. 1, a joint J3 (see FIG. 5) having the same structure as the joints J1 and J2 described above is adopted.

したがって、第1の連結部材6に対して支保材5(5A)を連結する場合は、第1の支保材取付け部62、すなわちジョイントJ3の接合板Dと支保材5(5A)の接合板Dとを対向させ、この状態で双方のボルト挿入穴Hにボルトを通してナットで接合板Dどうしを強く締め付け固定すればよく、これにより、第1の連結部材6に対する支保材5(5A)の連結は完了する。   Therefore, when connecting the supporting member 5 (5A) to the first connecting member 6, the first supporting member attaching portion 62, that is, the joint plate D of the joint J3 and the joint plate D of the supporting member 5 (5A). And, in this state, the bolts can be passed through both bolt insertion holes H and the joining plates D can be strongly tightened and fixed with a nut, whereby the support member 5 (5A) can be connected to the first connecting member 6.

図1の重量物搬送構造TRでは、巻上機4のワイヤー3が第1の連結部材6上を通過するため、第1の連結部材6との摩擦によるワイヤー3の擦れを防止する手段として、第1の連結部材6の上面にローラ8を設けている。このローラ8の外周面に対してワイヤー3が当接し、かつ、ワイヤー3とローラ8との摩擦力によってローラ8が回転することにより、ワイヤー3の擦れは防止される。   In the heavy load transport structure TR of FIG. 1, since the wire 3 of the hoisting machine 4 passes over the first connecting member 6, as means for preventing rubbing of the wire 3 due to friction with the first connecting member 6, A roller 8 is provided on the upper surface of the first connecting member 6. The wire 3 comes into contact with the outer peripheral surface of the roller 8 and the frictional force between the wire 3 and the roller 8 causes the roller 8 to rotate, whereby the rubbing of the wire 3 is prevented.

《第2の連結部材7の詳細》
第2の連結部材7は、第3の締結手段B3(図1の例ではボルトとナット)によって支保材5の他端部が着脱自在に取付けられる第2の支保材取付け部71と、第4の締結手段B4(図1の例ではボルトとナット)によって巻上機4が着脱自在に取付けられる巻上機取付け部72と、を有している。
<< Details of the second connecting member 7 >>

第2の支保材取付け部71の具体的な構造例として、図1の重量物搬送構造TRにおいては、第1の支保材取付け部62と同じく、前述のジョイントJ1、J2と同じ構造のジョイントJ4(図5参照)を採用している。   As a specific structural example of the second supporting material mounting portion 71, in the heavy load transport structure TR of FIG. 1, as with the first supporting material mounting portion 62, a joint J4 having the same structure as the joints J1 and J2 described above. (See FIG. 5) is adopted.

したがって、第2の支保材取付け部71に対して支保材5(5B)を連結する場合は、第2の支保材取付け部71、すなわちジョイントJ4の接合板Dと支保材5(5B)の接合板Dとを対向させ、この状態で双方のボルト挿入穴Hにボルトを通してナットで接合板Dどうしを強く締め付け固定すればよく、これにより、第2の連結部材6に対する支保材5(5B)の連結は完了する。   Therefore, when connecting the supporting material 5 (5B) to the second supporting material mounting portion 71, the second supporting material mounting portion 71, that is, the joining plate D of the joint J4 and the supporting material 5 (5B) is joined. The plate D may be opposed to each other, and in this state, bolts may be passed through both bolt insertion holes H and the joining plates D may be strongly tightened and fixed with a nut, whereby the support member 5 (5B) for the second connecting member 6 is secured. The connection is complete.

《重量物搬送構造TRの利用例とその組立・分解作業等の説明》
図1の重量物搬送構造TRは、例えば図1に示すような階段S1で重量物を運搬する場合に利用される。その際、同図の重量物搬送構造TRは、階段S1まではコンパクトに分解された状態、すなわちレール片20、支保材5、巻上機4、第1および第2の連結部材6、7等のような小部品に分解された状態で搬入され、階段S1やその上下フロア面F1、F2で組み立てられる。
<< Explanation of usage example of heavy load transport structure TR and its assembly / disassembly work >>
The heavy load transport structure TR of FIG. 1 is used, for example, when transporting a heavy load on stairs S1 as shown in FIG. At that time, the heavy goods transport structure TR of the same figure is in a state in which it is compactly disassembled up to the step S1, that is, the rail piece 20, the supporting member 5, the hoisting machine 4, the first and second connecting members 6 and 7, and the like. It is carried in a state of being disassembled into such small parts and assembled on the stairs S1 and the upper and lower floor surfaces F1 and F2.

階段S1およびその下のフロア面F1では、仮設レール2の組立てを行う。その組立て作業は、まず、階段S1の床面に養生パネルを敷き、次に、階段S1に沿って支持柱21を立てる。そして、立てた各支持柱21の先端部に図示しない取付け金具を介してレール片20を取付けるとともに、取付けたレール片20の端部どうしを前記取付け金具のジョイント部で連結する。これにより、一本の仮設レール2が組み立てられた状態になる。   On the stairs S1 and the floor surface F1 below the stairs S1, the temporary rails 2 are assembled. In the assembling work, first, a curing panel is laid on the floor surface of the stairs S1, and then the support columns 21 are stood along the stairs S1. Then, the rail piece 20 is attached to the leading end of each of the standing support columns 21 via an attachment fitting (not shown), and the ends of the attached rail pieces 20 are connected by the joint portion of the attachment attachment. As a result, one temporary rail 2 is assembled.

前記仮設レール2を2本組立て、これら2本の仮設レール2、2をそれぞれ支持している支持柱21間が幅決めアングル鋼材22で連結固定されることにより、階段S1およびその下のフロア面F1での仮設レール2の組立ては完了する。   By assembling the two temporary rails 2 and connecting and supporting between the support columns 21 respectively supporting these two temporary rails 2 and 2 with a width determining angle steel material 22, the stairs S1 and the floor surface thereunder The assembly of the temporary rail 2 in F1 is completed.

階段S1上のフロア面F1では、前記2本の仮設レール2の延長線より外側の左右スペースに支保材5を1本ずつ配置し、配置した支保材5を介する仮設レール2と巻上機4との連結・組立て作業を行う。この連結・組立て作業は、具体的には、(1)第1の連結部材を介して仮設レールと支保材とを連結する作業、(2)第2の連結部材を介して仮設レールと巻上機とを連結する作業である。   On the floor surface F1 on the stairs S1, the support members 5 are arranged one by one in the left and right spaces outside the extension lines of the two temporary rails 2, and the temporary rail 2 and the hoisting machine 4 through the arranged support members 5 are arranged. Performs connection and assembly work with. Specifically, this connecting / assembling work includes (1) an operation of connecting the temporary rail and the supporting member via the first connecting member, and (2) a temporary rail and hoisting via the second connecting member. It is a work to connect the machine.

以上説明した仮設レール2の組立て作業と、支保材5を介する仮設レール2、2と巻上機4との連結・組立て作業は、同時並行的に行うことができ、これらの作業の終了をもって、図1の重量物搬送構造TRの組立ては完了する。   The assembling work of the temporary rail 2 and the connecting / assembling work of the temporary rails 2 and 2 and the hoisting machine 4 through the supporting member 5 described above can be performed in parallel at the same time, and when these works are completed, The assembly of the heavy goods transport structure TR of FIG. 1 is completed.

そして、以上のようにして組立てられた図1の重量物搬送構造TRを利用して、階段S1下のフロア面F1から階段S1上のフロア面F2まで重量物HOを搬送する際は、フロア面F1で台車1に重量物HOを乗せる作業、当該台車1の車輪を2本の仮設レール2上に導く作業、および、ワイヤー3のフック(図示省略)を台車1に引っ掛ける作業を行った後、巻上機4でワイヤー3を巻き取る。これにより、図3に示したように、台車1が仮設レール2上を走行することで、重量物HOは、階段S1下のフロア面F1から階段S1上のフロア面F2まで搬送される。   When the heavy object transport structure TR of FIG. 1 assembled as described above is used to transport the heavy object HO from the floor surface F1 below the stairs S1 to the floor surface F2 above the stairs S1, the floor surface After carrying out the work of placing the heavy object HO on the trolley 1 by F1, the work of guiding the wheels of the trolley 1 onto the two temporary rails 2, and the work of hooking the hook (not shown) of the wire 3 on the trolley 1, The winding machine 4 winds up the wire 3. As a result, as shown in FIG. 3, the trolley 1 travels on the temporary rail 2, whereby the heavy load HO is transported from the floor surface F1 below the stairs S1 to the floor surface F2 above the stairs S1.

前記のように階段S1上のフロア面F2まで重量物HOを搬送した後は、図4に示したように、図1の重量物搬送構造TRから一方の支保材5を取外すことによって台車出口EXを設け、この台車出口EXから台車1を引き出すことで、階段S1における重量物HOの搬送作業は完了する。   After carrying the heavy load HO to the floor surface F2 on the stairs S1 as described above, as shown in FIG. 4, by removing one of the supporting members 5 from the heavy load transport structure TR of FIG. Is provided and the carriage 1 is pulled out from the carriage exit EX, whereby the work of transferring the heavy load HO on the stairs S1 is completed.

また、図1の重量物搬送構造TRは、前記搬送とは逆の方向への搬送、すなわち階段S1上のフロア面F2から階段S1下のフロア面F1まで重量物HOを降す形式の搬送にも利用できる。この場合は、フロア面F2で台車1に重量物HOを乗せる作業、当該台車1の車輪を2本の仮設レール2上に導く作業、および、ワイヤー3のフック(図示省略)を台車1に引っ掛ける作業を行った後、フロア面F1側への台車1の下降移動に応じて、巻上機4からワイヤー3を少しずつ繰り出す作業を行えばよい。   In addition, the heavy load transport structure TR of FIG. 1 is a transport in a direction opposite to the above transport, that is, a type of transport in which the heavy load HO is lowered from the floor surface F2 above the stairs S1 to the floor surface F1 below the stairs S1. Is also available. In this case, the work of placing the heavy object HO on the truck 1 on the floor surface F2, the work of guiding the wheels of the truck 1 onto the two temporary rails 2, and the hook of the wire 3 (not shown) is hooked on the truck 1. After performing the work, it is sufficient to perform the work of gradually unwinding the wire 3 from the hoisting machine 4 in accordance with the downward movement of the trolley 1 toward the floor surface F1 side.

以上説明したように重量物HOの搬送が完了した後、図1の重量物搬送構造TRは、その組立て前の状態、すなわちレール片20、支保材5、巻上機4、第1および第2の連結部材6、7等のようなコンパクトな小部品に解体されて、別の現場または保管場所に搬送される。   After the transportation of the heavy load HO is completed as described above, the heavy load transport structure TR of FIG. 1 is in a state before being assembled, that is, the rail piece 20, the support member 5, the hoisting machine 4, the first and the second. It is disassembled into compact small parts such as the connecting members 6 and 7 and transported to another site or storage location.

ところで、前記のような重量物HOの搬送において、台車1が仮設レール2上に乗る前に巻上機4でワイヤー4を巻き取り始めると、その巻取りの反力によって巻上機4、支保材5、仮設レール2が台車1の方向に引きずられようとする。   By the way, in transporting the heavy load HO as described above, when the wire 4 is started to be wound by the hoisting machine 4 before the carriage 1 rides on the temporary rail 2, the hoisting machine 4 and the supporting mechanism are supported by the hoisting reaction force. The material 5 and the temporary rail 2 tend to be dragged toward the carriage 1.

しかしながら、図1の重量物搬送構造TRによると、台車1が仮設レール2上に少しでも乗っかっていれば、前記のような巻取の反力による引きずり現象は生じない。   However, according to the heavy goods transport structure TR of FIG. 1, if the carriage 1 is on the temporary rail 2 for a while, the dragging phenomenon due to the reaction force of the winding does not occur.

その理由は要するに、図1の重量物搬送構造TRでは、支保材5によって仮設レール2と巻上機4とが連結される構造を採用することで、巻上機4は支保材5を介して仮設レール2と一体化しているので、重量物HOを積載した台車1が仮設レール2上に少しでも乗っかった後は、巻上機4でのワイヤー3の巻取り時に生じる力、すなわち、台車1と巻上機4との間で引き合う力は、支保材5を圧縮する力となって相殺されるからである。   The reason is that, in the heavy goods transport structure TR of FIG. 1, the structure in which the temporary rail 2 and the hoisting machine 4 are connected by the supporting material 5 is adopted, so that the hoisting machine 4 interposes the supporting material 5. Since it is integrated with the temporary rail 2, the force generated when the wire 3 is wound by the hoisting machine 4, that is, the trolley 1 after the trolley 1 on which the heavy load HO is loaded rides on the temporary rail 2 as much as possible. This is because the force of attraction between the hoisting machine 4 and the hoisting machine 4 is offset by the force of compressing the supporting member 5.

従って、図1の重量物搬送構造TRによると、重量物HOの搬送現場における既設建物の一部(例えば、柱、梁、床、天井あるいは壁)に穴を開け、その穴にアンカーを打って巻上機4を固定したり、巻上機4以外の部材(例えば仮設レール2、支保材5)を同様に固定したりする必要がないことから、下記(3−1)から(3−5)のような作用効果が得られる。   Therefore, according to the heavy load transport structure TR of FIG. 1, a hole is made in a part (for example, a pillar, a beam, a floor, a ceiling, or a wall) of an existing building at the transport site of the heavy load HO, and an anchor is struck in the hole. Since it is not necessary to fix the hoisting machine 4 or the members other than the hoisting machine 4 (for example, the temporary rail 2 and the supporting member 5) in the same manner, the following (3-1) to (3-5) ) Like effect is obtained.

(3−1)穴開け工事によって既設建物の構造自体にダメージを与えるおそれがない。
(3−2)穴開け工事やアンカー打ち工事のような騒音や粉塵が発生することもない。
(3−3)穴開け工事だけでなく、その穴開け工事で開けた穴を後で埋める補修作業も不要であり、重量物HOの設置に要する工事期間の短縮と、工事費用の低減を図れる。
(3−4)重量物搬送現場では、手間と時間を要する穴開け工事やアンカー打ち工事を必要とせず、仮設レール2と巻上機4を支保材5で連結する組立・設置作業とその連結を解除する解体・撤去作業を行うだけでよく、そのような組立・設置から解体・撤去に要する時間と重量物HOの搬送に要する時間は合計で約30分から1時間程度で済むから、重量物搬送現場付近の施設の営業に支障が生じることは殆どない。重量物搬送現場が例えば既設駅であるとしたら、その既設駅の階段における重量物HOの搬送は終電から始発までの間の短時間に行うことができ、既設駅や駅利用者に迷惑をかけることもない。
(3−5)巻上機4はアンカーで固定しなくてもよいので、アンカーや他の方法でも巻上機4を固定できない現場でも、重量物の搬送が可能である。
(3-1) There is no risk of damaging the structure of the existing building due to the drilling work.
(3-2) No noise or dust is generated unlike the drilling work and anchoring work.
(3-3) Not only the drilling work, but also the repair work to fill the holes drilled by the drilling work later is not required, and the construction period required for installing the heavy load HO can be shortened and the construction cost can be reduced. .
(3-4) Assembling / installing work for connecting the temporary rail 2 and the hoisting machine 4 with the supporting material 5 and the connection therefor without requiring time-consuming and time-consuming drilling work and anchor striking work at the heavy load transport site. It is only necessary to carry out dismantling / removing work to release, and the time required for dismantling / removing from such assembly / installation and the time required for carrying heavy HO is about 30 minutes to 1 hour in total. There is almost no obstacle to the operation of the facilities near the transportation site. If the heavy goods transport site is, for example, an existing station, the heavy goods HO can be carried on the stairs of the existing station in a short time from the last train to the first train, which causes trouble to existing stations and station users. Nothing.
(3-5) Since the hoisting machine 4 does not have to be fixed by an anchor, it is possible to carry heavy objects even at a site where the hoisting machine 4 cannot be fixed by an anchor or another method.

《他の実施形態》
図1の重量物搬送構造TRは、その利用例1として、階段S1の上下フロア面F1、F2を結ぶ経路R1に沿って重量物HOを搬送するときに利用されるものであるが、これとは別に、図1の重量物搬送構造TRは、例えば、利用例2として、図7に示す段差S2に設置し、段差S2の上下を結ぶ経路R2に沿って重量物HOを搬送するときや、利用例3として、図8に示すような障害物S3(例えば配管など)を乗り越える経路R3に沿って重量物HOを搬送するときに利用することができる。
<< Other Embodiments >>
As a first usage example thereof, the heavy load transport structure TR of FIG. 1 is used to transport a heavy load HO along a route R1 connecting the upper and lower floor surfaces F1 and F2 of the stairs S1. Separately, for example, when the heavy load transport structure TR of FIG. 1 is installed at the step S2 shown in FIG. 7 as a usage example 2 and the heavy load HO is transported along the path R2 connecting the upper and lower sides of the step S2, As a usage example 3, it can be used when the heavy object HO is transported along a route R3 that goes over an obstacle S3 (for example, a pipe) as shown in FIG.

前記利用例1と利用例2、3との相違点は、段差S2の上下を結ぶ経路、又は、障害物S3を乗り越える経路に沿って仮設レール2が設置される点であり、その点以外は共通であるため、利用例2、3の詳細説明は省略する。このような利用例2、3でも重量物の搬送現場における既設建物の一部に穴を開け、その穴にアンカーを打って巻上機を固定したり、巻上機以外の部材(例えば仮設レール、支保材)を同様に固定したりする必要がないから、前述の(3−1)から(3−5)の作用効果が得られる。   The difference between the use example 1 and the use examples 2 and 3 is that the temporary rail 2 is installed along the route connecting the upper and lower sides of the step S2 or the route over the obstacle S3, except for that point. Since they are common, detailed description of usage examples 2 and 3 will be omitted. Even in such usage examples 2 and 3, a hole is made in a part of an existing building at a site for transporting heavy objects, an anchor is struck in the hole to fix the hoist, or a member other than the hoist (for example, a temporary rail). Since it is not necessary to similarly fix the supporting material), the above-mentioned effects (3-1) to (3-5) can be obtained.
