Abstract
Description
本発明は、エレベータの据付作業に用いられるエレベータの据付装置、及びこの据付装置の組立方法に関する。 The present invention relates to an elevator installation device used for elevator installation work, and an assembly method of the installation device.
従来より、エレベータの据付作業では、据付対象となる建屋内のエレベータ昇降路の全高及び機械室の躯体造作が完了した後に、エレベータの据付を行うのが最も安全かつ効率的である。しかし、近年のビルの超高層化に伴い、発注者よりエレベータの早期完成が要請され、エレベータの全高及び機械室の躯体が完成される前に、最下階と最上階との間の途中階の乗場より下方でエレベータの据付を先行して行うことによりエレベータの完成時期を早め、このエレベータを利用することで建物全体の工期を早める必要性が生じている。 Conventionally, in the elevator installation work, it is safest and most efficient to install the elevator after the overall height of the elevator hoistway in the building to be installed and the building of the machine room are completed. However, with the recent rise in the height of buildings, the orderer requested the early completion of the elevator, before the overall height of the elevator and the machine room frame were completed, the intermediate floor between the lowest floor and the top floor. There is a need to advance the completion of the elevator by installing the elevator in advance below the platform, and to advance the construction period of the entire building by using this elevator.
一方、現在行われているエレベータの据付作業では、昇降路内に足場を必要としない、いわゆる「足場無し工法」が採用されているので、昇降路内に足場は設置されていない。従って、このような条件下で途中階の乗場から上方へエレベータの据付を行うためには、この途中階の乗場から昇降路へ足場を設置する必要がある。 On the other hand, in the current elevator installation work, a so-called “no scaffolding method” that does not require a scaffold in the hoistway is adopted, so no scaffold is installed in the hoistway. Therefore, in order to install the elevator upward from the landing on the intermediate floor under such conditions, it is necessary to install a scaffold from the landing on the intermediate floor to the hoistway.
そこで、昇降路に足場を設置する従来技術の1つとして、鉄骨柱、鉄骨梁等からなる鉄骨造の多層の建物躯体を構築しながら、エレベータシャフトとなる部分以外の部分の周囲を含む鉄骨梁上の所定の部分にデッキプレート、プレキャストコンクリート板等の板体を載設し、かつエレベータシャフトとなる部分の両側に位置する鉄骨梁間に複数の支持梁を配し、各支持梁の両端部を鉄骨梁に着脱可能に支持させ、支持梁の上側に板状体を着脱可能に取付けたエレベータシャフト及びエレベータの組立施工法が提案されている(例えば、特許文献1参照)。 Therefore, as one of the conventional techniques for installing a scaffolding in a hoistway, a steel beam including the periphery of the part other than the part that becomes the elevator shaft, while constructing a multi-layered steel frame consisting of steel columns, steel beams, etc. A plate body such as a deck plate or a precast concrete plate is placed on a predetermined part above, and a plurality of support beams are arranged between the steel beams located on both sides of the part to be the elevator shaft, and both ends of each support beam are connected to each other. An elevator shaft that is detachably supported by a steel beam and a plate-like body is detachably attached to the upper side of the support beam and an elevator assembly method have been proposed (see, for example, Patent Document 1).
しかし、上述した特許文献1に開示された従来技術のエレベータシャフト及びエレベータの組立施工法は、各支持梁の上側の板状体がエレベータシャフトとなる部分を各層毎に塞ぐことにより、作業者がエレベータシャフト内で作業を行う際の安全が図られているが、各支持梁及び板状体の配設作業における安全性についてまでは、十分に考慮されていない。従って、このようなエレベータの据付作業が行われる足場を安全に設置するために、作業者はより注意を払う必要があるので、足場の設置作業に多くの時間を費やすことが懸念されている。 However, according to the prior art elevator shaft and elevator assembly method disclosed in Patent Document 1 described above, the upper plate-like body of each support beam closes the portion that becomes the elevator shaft for each layer. Although safety is ensured when working in the elevator shaft, sufficient consideration is not given to the safety in the work of disposing each support beam and plate-like body. Therefore, since it is necessary for an operator to pay more attention in order to safely install a scaffold on which such elevator installation work is performed, there is a concern that a lot of time may be spent on the installation work of the scaffold.
本発明は、このような従来技術の実情からなされたもので、その目的は、エレベータの据付作業を行うための足場をより安全かつ効率良く設置することができるエレベータの据付装置、及びこの据付装置の組立方法を提供することにある。 The present invention has been made based on the actual situation of the prior art as described above, and an object of the present invention is to provide an elevator installation apparatus capable of installing a scaffold for performing an elevator installation operation more safely and efficiently, and the installation apparatus.
