Description

この発明は、エレベータの据付のために使用される据付作業床装置、並びに据付作業床装置の組立方法に関するものである。   The present invention relates to an installation work floor device used for installing an elevator, and an assembly method of the installation work floor device.

エレベータを建物に据え付けるためには、エレベータの運転に必要な機器類、及びそれらの機器類を揚重及び取り付けるための機材等を、昇降路の頂部や中間部に設置（或いは、仮設）しなければならない。特に、昇降路の上方に機械室が備えられていない機械室エレベータの据付時や、エレベータのモダニゼーションでは、このような作業が多く発生する。   In order to install the elevator in the building, the equipment necessary for the operation of the elevator and the equipment for lifting and mounting these equipment must be installed (or temporarily) at the top or middle of the hoistway. I must. In particular, such work often occurs during installation of a machine room elevator that does not include a machine room above the hoistway or in modernization of the elevator.

上述のようなエレベータの据付作業において、昇降路のピットから足場を組み上げていたのでは、特に建物が高い場合に作業効率が著しく低下してしまう。このため、これまでにも、エレベータの乗場側から取り付けることができる据付作業床装置が、数多く提案されている。
エレベータの乗場側から組立可能な据付作業床装置の従来技術として、例えば、エレベータの乗場に立設された縦柱に２本の斜め梁（斜材、支持材）を連結し、据付作業員が乗るための作業床を、この２本の斜め梁によって支持するものが提案されている（特許文献１参照）。 In the installation work of the elevator as described above, if the scaffold is assembled from the pit of the hoistway, the work efficiency is remarkably lowered particularly when the building is high. For this reason, many installation work floor apparatuses which can be attached from the elevator landing side have been proposed so far.
As a conventional technology of an installation work floor device that can be assembled from the elevator landing side, for example, two diagonal beams (diagonal material, support material) are connected to a vertical column standing on the elevator landing, There has been proposed one that supports a working floor for riding by these two diagonal beams (see Patent Document 1).

他の従来技術として、作業床を水平梁上に組み立てるとともに、この水平梁を、乗場に立設された縦柱と昇降路奥側の壁面とによって支持するものが提案されている（例えば、特許文献２参照）。
また、他の従来技術として、上下二階床の乗場を使用して、作業床を昇降路内に設置するものも提案されている（例えば、特許文献３参照）。 As another conventional technique, a work floor is assembled on a horizontal beam, and the horizontal beam is supported by a vertical column standing on a landing and a wall surface on the back side of a hoistway (for example, a patent) Reference 2).
In addition, as another conventional technique, there is also proposed one in which a work floor is installed in a hoistway using a landing floor of upper and lower second floors (for example, see Patent Document 3).

特開２００５−８９１４８号公報JP 2005-89148 A 特開平９−１９４１６０号公報JP-A-9-194160 特開２０００−３２８７７７号公報JP 2000-328777 A

特許文献１記載のものでは、昇降路が広くなる（即ち、昇降路の平面寸法が大きくなる）と、作業床を支持する水平梁や斜め梁（支持材９）の長さが必然的に長くなってしまい、所定の強度を確保するためにその重量も増加してしまう。このため、据付作業床装置の組み立てを行う作業員の人数を増やしたり、安全対策を強化したりしなければならず、作業効率が悪化するといった問題があった。   In the thing of patent document 1, when the hoistway becomes wide (namely, the plane dimension of the hoistway becomes large), the length of the horizontal beam and the diagonal beam (support material 9) which support a work floor inevitably becomes long. In other words, the weight increases to ensure a predetermined strength. For this reason, the number of workers for assembling the installation work floor device has to be increased or safety measures have to be strengthened, resulting in a problem that work efficiency deteriorates.

また、特許文献２記載のものでは、昇降路奥側の壁面によって据付作業床装置の一部を支持しているため、上記壁面の構成によっては、作用する荷重を支持できない場合があった。特に高層建物では、鉄骨や荷重支持力の弱い石膏ボード等によって昇降路が構成される場合が多い。したがって、かかる場合は、昇降路奥側の壁面によって据付作業床装置を支持することができず、特許文献２記載のものを適用できないことがあった。   Moreover, in the thing of patent document 2, since a part of installation work floor apparatus is supported by the wall surface of the hoistway back | inner side, depending on the structure of the said wall surface, the load which acts may not be supported. Particularly in a high-rise building, the hoistway is often constituted by a steel frame or a gypsum board having a weak load supporting ability. Therefore, in such a case, the installation work floor device cannot be supported by the wall surface on the back side of the hoistway, and the one described in Patent Document 2 may not be applied.

また、特許文献３記載のものでは、据付作業床装置を設置するために、上下二階床の乗場を使用しなければならない。このため、階間が長い場合やシャトルエレベータのように停止階が連続していない場合には、構成部材の寸法及び重量が著しく増加したり、据付作業床装置の設置が困難になったりするといった問題があった。   Moreover, in the thing of patent document 3, in order to install an installation work floor apparatus, you have to use the landing of the upper and lower two floors. For this reason, when the floors are long or when the stop floors are not continuous as in a shuttle elevator, the size and weight of the structural members are remarkably increased, or the installation work floor device is difficult to install. There was a problem.

この発明は、上述のような課題を解決するためになされたもので、その目的は、昇降路の広さや昇降路の壁面の強度等に関わらず種々のエレベータに対応することができ、更に、乗場側から簡単に組み立てることができるエレベータの据付作業床装置と、その組立方法とを提供することである。   The present invention has been made to solve the above-described problems, and its purpose can be applied to various elevators regardless of the width of the hoistway, the strength of the wall surface of the hoistway, and the like. It is an object to provide an elevator installation work floor device that can be easily assembled from a landing side, and an assembling method thereof.

次に、図２乃至図７に基づき、上記構成を有する据付作業床装置５の組立方法について具体的に説明する。図２乃至図７は図１に示す据付作業床装置の組立方法を説明するための図である。
エレベータの据付作業員は、据付作業床装置５を図１に示す状態に組み立てる場合、先ず、最上階の乗場２において、アンカーボルト１２を利用して床面２ａに基部６を強固に固定する。そして、縦柱７の下端部を基部６に固定して縦柱７を乗場２に立設し、その上端部を、支持部材１３を介して開口４上方の乗場壁３に支持させる。 Next, based on FIG. 2 thru | or FIG. 7, the assembly method of the installation work floor apparatus 5 which has the said structure is demonstrated concretely. 2 to 7 are views for explaining a method of assembling the installation work floor apparatus shown in FIG.
When assembling the installation work floor device 5 in the state shown in FIG. 1, first, the elevator installation worker first firmly fixes the base 6 to the floor 2 a using the anchor bolts 12 at the landing 2 on the top floor. And the lower end part of the vertical column 7 is fixed to the base 6, the vertical column 7 is erected on the landing 2, and the upper end portion is supported by the landing wall 3 above the opening 4 via the support member 13.

据付作業員は、上記２分割構成からなる斜め梁１０を、予め、一端側１０ａと他端側１０ｂとを重ね合わせて半分に折り畳んだ状態にしておき、一端部を縦柱７の下端部に回動自在に連結する。また、斜め梁１０の一端部を縦柱７の下端部に連結する前、或いは連結した後に、補助梁１１の一端部を斜め梁１０の中間部に回動自在に連結する。据付作業員は、斜め梁１０の一端部を縦柱７の下端部に連結し、且つ補助梁１１の一端部を斜め梁１０の中間部に連結した後、補助梁１１の一端部を昇降路１内に押し出して、斜め梁１０をその一端部を中心に回転させる。そして、斜め梁１０の一端側１０ａを、乗場２から斜め上方に向けて昇降路１内に突出させる。また、斜め梁１０の上記配置を保持したまま補助梁１１を水平に配置し、補助梁１１の他端部を縦柱７の中間部に固定する（図３参照）。   The installation worker puts the oblique beam 10 having the above-described two-divided configuration in advance in a state where the one end side 10a and the other end side 10b are overlapped and folded in half, and one end portion is set to the lower end portion of the vertical column 7. It connects so that it can rotate freely. Further, before or after connecting one end portion of the diagonal beam 10 to the lower end portion of the vertical column 7, one end portion of the auxiliary beam 11 is rotatably connected to an intermediate portion of the diagonal beam 10. The installation worker connects one end portion of the diagonal beam 10 to the lower end portion of the vertical column 7 and connects one end portion of the auxiliary beam 11 to the middle portion of the diagonal beam 10, and then connects one end portion of the auxiliary beam 11 to the hoistway. 1 and the diagonal beam 10 is rotated around its one end. And the one end side 10a of the diagonal beam 10 is protruded in the hoistway 1 toward diagonally upward from the landing 2. Further, the auxiliary beam 11 is arranged horizontally while maintaining the above-described arrangement of the oblique beam 10, and the other end of the auxiliary beam 11 is fixed to the middle part of the vertical column 7 (see FIG. 3).

次に、据付作業員は、図４に示すように、斜め梁１０の他端側１０ｂを、一端側１０ａとの連結部分を中心に回転させるように持ち上げ、その他端部を水平梁８の先端側に回動自在に連結する。なお、乗場２の間口方向に所定の間隔を有して立設された２本の縦柱７（図１乃至図７においては、一方の縦柱７のみ図示されており、一方の縦柱７に重なって配置された他方の縦柱７は図示されていない）間には、補助梁１１の設置高さよりも上方位置で、且つ水平梁８の設置高さよりも下方位置に、補助部材１７が水平に設けられている。このため、据付作業員は、例えば、図４に示すように、水平梁８を補助部材１７に立て掛けておき、その状態で、斜め梁１０の他端側１０ｂと水平梁８との連結作業を行う。   Next, as shown in FIG. 4, the installation worker lifts the other end side 10 b of the oblique beam 10 so as to rotate around the connecting portion with the one end side 10 a, and lifts the other end to the tip of the horizontal beam 8. It is connected to the side so that it can rotate freely. It should be noted that only two vertical pillars 7 (in FIG. 1 to FIG. 7, only one vertical pillar 7 is shown, and one vertical pillar 7 is erected at a predetermined interval in the frontage direction of the hall 2. (The other vertical column 7 arranged to overlap the vertical beam 7 is not shown), and the auxiliary member 17 is located above the installation height of the auxiliary beam 11 and below the installation height of the horizontal beam 8. It is provided horizontally. Therefore, for example, as shown in FIG. 4, the installation worker leans the horizontal beam 8 against the auxiliary member 17, and in that state, connects the other end side 10 b of the diagonal beam 10 and the horizontal beam 8. Do.

斜め梁１０の他端部を水平梁８に連結した後、据付作業員は、水平梁８の先端側を昇降路１内に押し出して、斜め梁１０の他端側１０ｂを一端側１０ａとの連結部分を中心に回転させる。そして、斜め梁１０が乗場２から斜め上方に向けて昇降路１内に突出するように、上記他端側１０ｂを一端側１０ａに対して一直線状に配置する。また、斜め梁１０の上記配置を保持したまま水平梁８を水平に配置し、水平梁８の一端部を縦柱７の上端部寄りに固定する（図５参照）。   After connecting the other end of the diagonal beam 10 to the horizontal beam 8, the installation worker pushes the distal end side of the horizontal beam 8 into the hoistway 1 so that the other end side 10b of the diagonal beam 10 is connected to the one end side 10a. Rotate around the connecting part. Then, the other end side 10b is arranged in a straight line with respect to the one end side 10a so that the oblique beam 10 projects into the hoistway 1 obliquely upward from the landing 2. Further, the horizontal beam 8 is arranged horizontally while maintaining the above arrangement of the oblique beam 10, and one end of the horizontal beam 8 is fixed near the upper end of the vertical column 7 (see FIG. 5).

なお、補助部材１７が上記配置に設けられている場合には、図５に示すように、水平梁８を補助部材１７に支持させた状態で水平梁８を昇降路１内に押し出せば、上記作業をより簡単に行うことができる。   In the case where the auxiliary member 17 is provided in the above arrangement, as shown in FIG. 5, if the horizontal beam 8 is pushed into the hoistway 1 with the horizontal beam 8 supported by the auxiliary member 17, The above operation can be performed more easily.

水平梁８を縦柱７に固定した後、据付作業員は、図６に示すように、縦柱７の下端部と水平梁８とに梯子１６を固定する。そして、取り付けた梯子１６を利用して床板１４を手前側から順番に水平梁８に固定し、その後、床板１４の四方を取り囲むように手摺１５を立設する（図７参照）。
以上の手順によって、据付作業床装置５を図１に示す状態に組み立てることができる。 After fixing the horizontal beam 8 to the vertical column 7, the installation worker fixes the ladder 16 to the lower end portion of the vertical column 7 and the horizontal beam 8 as shown in FIG. 6. And the floor board 14 is fixed to the horizontal beam 8 in order from the near side using the attached ladder 16, and then the handrail 15 is erected so as to surround the four sides of the floor board 14 (see FIG. 7).
By the above procedure, the installation work floor device 5 can be assembled in the state shown in FIG.

この発明の実施の形態１によれば、据付作業床装置５を昇降路１の広さや昇降路１の壁面の強度等に関わらず種々のエレベータに対応させることができ、更に、乗場２側から簡単に組み立てることができるようになる。   According to the first embodiment of the present invention, the installation work floor device 5 can be adapted to various elevators regardless of the size of the hoistway 1 and the strength of the wall surface of the hoistway 1, and from the landing 2 side. Easy to assemble.

即ち、上記構成の据付作業床装置５は、従来技術のように、上下二階床の乗場を利用したり、昇降路１奥側の壁面を利用したりする必要はなく、１つの乗場２に自重及び積載荷重を支持させることができる。また、その組立において、補助梁１１を縦柱７に固定して斜め梁１０の一端側１０ａを動かないようにした後に、この斜め梁１０の一端側１０ａを利用して水平梁８と斜め梁１０の他端側１０ｂとを所望の位置に配置する２段階の押し出し手順を採用しているため、据付作業員は、昇降路１が広い場合であっても、組立時に乗場２から乗り出したり、無理な姿勢で重量物を支えたりする必要もない。   That is, the installation work floor device 5 having the above-described configuration does not need to use the upper and lower second floor landings or the wall on the back side of the hoistway 1 as in the prior art, and does not have to use one weight on one landing 2. And the load capacity can be supported. Further, in the assembly, after the auxiliary beam 11 is fixed to the vertical column 7 so that the one end side 10a of the oblique beam 10 does not move, the horizontal beam 8 and the oblique beam are utilized using the one end side 10a of the oblique beam 10. 10 adopts a two-step extrusion procedure in which the other end side 10b is arranged at a desired position, so that the installation worker can get out of the landing 2 during assembly even when the hoistway 1 is wide, There is no need to support heavy objects in an unreasonable posture.
