Description

この発明は、エレベータおよびエレベータのリニューアル方法に関し、特に、骨組構造体が昇降路内に設置されているエレベータをリニューアルする際に必要な、ガイドレールを固定するための立柱を昇降路内に敷設する方法、および立柱の敷設構造に関するものである。   The present invention relates to an elevator and a method of renewing an elevator, and in particular, erects a pillar in the hoistway for fixing a guide rail, which is necessary when renewing an elevator in which a frame structure is installed in the hoistway. The present invention relates to a method and a laying structure of a pillar.

一般に、エレベータにおいては、昇降路の壁又は囲い、および出入り口の戸などが、耐火被覆材で覆われている（例えば、特許文献１参照）。このようなエレベータをリニューアルする場合、搬入性の問題から、短いガイドレールが用いられる。短いガイドレールは、昇降路内の建築梁にブラケットを介して固定できないので、ガイドレールを固定するための立柱を、建築梁を利用して昇降路内に設置し、ガイドレールをブラケットを介して立柱に固定していた。   Generally, in an elevator, a wall or enclosure of a hoistway and a door of an entrance and the like are covered with a fireproof covering (see, for example, Patent Document 1). When renewing such an elevator, a short guide rail is used because of the problem of carrying in. Since a short guide rail can not be fixed to a building beam in the hoistway via a bracket, a standing column for fixing the guide rail is installed in the hoistway using the building beam, and the guide rail is via a bracket It was fixed to a standing pole.

立柱は、それぞれ、両端を上下に離間する建築梁に溶接されて、昇降路内に、建築梁の長さ方向に２列となって、上下方向に敷設される。このとき、上下に離間する建築梁の間の昇降路の壁に被覆されていた耐火被覆材を剥ぎ落とし、立柱を敷設した後、耐火被覆材を昇降路の壁に被覆する必要があり、立柱の敷設負荷が大きいという課題があった。   The upright columns are respectively welded to the building beams whose ends are vertically separated, and are laid in the vertical direction in two rows in the longitudinal direction of the building beams in the hoistway. At this time, it is necessary to peel off the fireproof covering material coated on the wall of the hoistway between building beams which are separated up and down and lay the upright pillar, and then coat the fireproof covering material on the hoistway wall. There was a problem that the laying load of

この発明は、上記課題を解決するためになされたもので、耐火被覆材の剥ぎ落とし量を削減し、立柱の敷設負荷を軽減できるエレベータのリニューアル方法およびエレベータを得ることを目的とする。   The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide an elevator renewal method and an elevator capable of reducing the removal amount of a fireproof covering material and reducing the laying load of a vertical column.

この発明のエレベータのリニューアル方法は、建築梁を四角形に組んだ複数の枠部材を、節点同士を建築柱で連結して、上下方向に組み上げて構成されて、昇降路内に設置された骨組構造体と、上記昇降路の壁に被覆された耐火被覆材と、を備えたエレベータのリニューアル方法であって、上記節点の周りの上記耐火被覆材を剥ぎ取る工程と、つなぎ部材を上記節点で直交する上記建築梁の間に架け渡し、上記つなぎ部材を上記建築梁に固定する工程と、立柱を上下方向に相対する上記つなぎ部材の間に配置し、上記立柱を上記つなぎ部材に固定する工程と、を備える。   A method of renewing an elevator according to the present invention is a frame structure installed in a hoistway, comprising a plurality of frame members in which building beams are assembled in a quadrangle, connecting the nodes by building columns and assembling them in the vertical direction. A method of renewing an elevator comprising a body and a fireproof covering coated on a wall of the hoistway, the step of peeling off the fireproof covering around the nodal point, and the connecting member being orthogonal to the nodal point Bridging between the building beams, fixing the connecting member to the building beam, arranging a vertical column between the vertical connecting members opposite to each other, and fixing the vertical column to the horizontal member; And.

この発明によれば、立柱を敷設するに先立って、節点の周りの耐火被覆材のみを剥ぎ取っているので、耐火被覆材の剥ぎ取り量が低減される。そこで、耐火被覆材の剥ぎ取り作業負荷および耐火被覆材の再吹き付け作業負荷が低減され、立柱の敷設負荷が軽減される。   According to the present invention, since only the fireproof covering material around the nodal point is peeled off prior to laying the erected column, the amount of peeling off of the fireproof covering material is reduced. Therefore, the load of stripping off the fireproof coating material and the load of re-spraying of the fireproof coating material are reduced, and the laying load of vertical columns is reduced.

FIG. 1 is a schematic view showing a frame structure installed in a hoistway of an elevator according to Embodiment 1 of the present invention, and FIG. 2 is a fireproof covering material in the elevator renewal method according to Embodiment 1 of the present invention. FIG. 3 is a perspective view of an essential part showing a state in which a connecting member is attached in the method of renewing an elevator according to Embodiment 1 of the present invention, and FIG. FIG. 5 is a view from the top of the vertical direction with the upright attached in the elevator renewal method according to the first aspect, and FIG. 5 is a horizontal direction with the upright attached in the elevator renewal method according to the first embodiment of the present invention. It is the figure seen from. In addition, in FIG. 1, only a part of fireproof coating material is illustrated for convenience.

図１において、骨組構造体１００は、４本の直線状の建築梁１１を四角形に組んだ枠部材１０を、節点同士を直線状の建築柱１２で連結して、鉛直方向、すなわち上下方向に複数段に組み上げて構成されている。なお、枠部材１０の節点が、一方の建築梁１１の端面を、他方の建築梁１１の端部の側面に突き合わせ、両者を溶接などにより剛接合して、構成されている。また、枠部材１０の節点が、建築柱１２と溶接などにより剛接合される。   In FIG. 1, the frame structure 100 is a vertical direction, that is, in the vertical direction, by connecting frame members 10 in which four straight building beams 11 are assembled in a quadrangle, and connecting nodes by straight building columns 12. It is built up in multiple stages. In addition, the node of the frame member 10 abuts the end face of one building beam 11 to the side face of the end of the other building beam 11 and is rigidly joined by welding or the like. Further, the nodes of the frame member 10 are rigidly connected to the building column 12 by welding or the like.

このように構成された骨組構造体１００は、例えば、昇降路のピットの床面に固定されて、昇降路内に上下方向に敷設される。そして、建築柱１２が、昇降路内の四隅に位置して上下方向に延びている。さらに、昇降路の壁が耐火材としての耐火被覆材４で覆われている。なお、図１では、骨組構造体１００は、建築柱１２を介して枠部材１０を４段に重ねて構成されているが、実際には、昇降路の上下方向の全長と同等の高さとなるように枠部材１０が多段に重ねられている。   The frame structure 100 configured in this manner is fixed to, for example, the floor surface of the pit of the hoistway, and is laid in the hoistway in the vertical direction. Then, the building columns 12 are located at four corners in the hoistway and extend in the vertical direction. Furthermore, the wall of the hoistway is covered with a fireproof covering 4 as a fireproofing material. In addition, in FIG. 1, although the frame structure body 100 is constructed by superposing the frame members 10 in four stages via the building columns 12, actually, the height is equivalent to the overall length in the vertical direction of the hoistway. Thus, the frame members 10 are stacked in multiple stages.

つぎに、このように構成されたエレベータのリニューアル方法について説明する。   Below, the renewal method of the elevator comprised in this way is demonstrated.

まず、図２に示されるように、枠部材１０の節点の周りの耐火被覆材４を剥ぎ取り、節点の周りの建築梁１１の上面を露出させる。ついで、図３に示されるように、例えば、Ｈ形鋼で作製されたつなぎ部材２０を節点で直交する建築梁１１間に架け渡し、溶接、ボルトによる締着などにより、建築梁１１に固定する。このようにして、つなぎ部材２０が、各節点の近傍に、建築梁１１の上部間に水平に架け渡される。   First, as shown in FIG. 2, the fireproof covering 4 around the nodal point of the frame member 10 is peeled off to expose the upper surface of the building beam 11 around the nodal point. Then, as shown in FIG. 3, for example, the bridge member 20 made of H-shaped steel is bridged between the building beams 11 orthogonal to each other at the nodes, and fixed to the building beams 11 by welding, bolting or the like. . In this manner, the bridging member 20 is bridged horizontally between the tops of the building beams 11 in the vicinity of each nodal point.

ついで、図４および図５に示されるように、例えば、Ｈ形鋼で作製された立柱１３を上下に離間するつなぎ部材２０間に配置し、立柱１３の端部を溶接、ボルトによる締着などにより、つなぎ部材２０に固定する。これにより、骨組構造体１００の四隅のそれぞれに、立柱１３が上下方向に一列に並んで敷設される。   Next, as shown in FIG. 4 and FIG. 5, for example, upright pillars 13 made of H-shaped steel are disposed between connecting members 20 which are vertically separated from each other, and the ends of the upright pillars 13 are welded, fastened by bolts, etc. It fixes to the connection member 20 by this. As a result, at each of the four corners of the frame structure 100, the upright columns 13 are laid in a line in the vertical direction.

ついで、図示していないが、耐火被覆材４が剥ぎ取られた部分に、難燃材料を吹き付けて、昇降路１の壁２を耐火被覆材４で覆う。その後、図示していないが、新規のガイドレールを搬入し、ブラケットを用いて、ガイドレールを立柱１３に取り付ける。さらに、新規の巻上機を機械室に据え付け、新規のかごやつり合いおもりを昇降路に据え付ける、などの必要なリニューアル作業を行う。   Then, although not shown, a flame retardant material is sprayed on the portion where the fireproof covering material 4 is peeled off, and the wall 2 of the hoistway 1 is covered with the fireproof covering material 4. Thereafter, although not shown, a new guide rail is carried in, and the guide rail is attached to the upright post 13 using a bracket. In addition, new renewal machines will be installed in the machine room, new cages and counterweights will be installed in the hoistway, and other necessary renewal work will be carried out.

ここで、比較のために、図１２を用いて従来の立柱１３の据え付け方法を説明する。   Here, for comparison, a conventional method of installing the vertical post 13 will be described with reference to FIG.

まず、上下に離間する建築梁１１間の、昇降路１の壁２に被覆されていた耐火被覆材４を剥ぎ取り、上下に離間する建築梁１１間に立柱１３を配置する。ついで、立柱１３の両端部を建築梁１１のそれぞれに溶接、ボルトの締着などにより固定する。そこで、２本の立柱１３が、図１２に示されるように、建築梁１１の長さ方向に離間して建築梁１１間に配設される。同様にして、立柱１３が上下方向に離間する建築梁１１間のそれぞれに２本ずつ配設される。これにより、立柱１３が、昇降路の相対する壁面のそれぞれに、建築梁１１の長さ方向に２列となって上下方向に延びるように敷設され、ガイドレールがブラケットを介して立柱１３に取り付けられる。   First, the fireproof covering material 4 coated on the wall 2 of the hoistway 1 is peeled off between building beams 11 vertically spaced from each other, and vertical pillars 13 are arranged between the building beams 11 vertically spaced from each other. Then, both ends of the vertical column 13 are fixed to each of the building beams 11 by welding, bolt fastening or the like. Therefore, two vertical columns 13 are disposed between the building beams 11 apart from each other in the longitudinal direction of the building beam 11 as shown in FIG. Similarly, two vertical pillars 13 are disposed between the building beams 11 which are vertically separated. Thus, the vertical columns 13 are laid on each of the opposing wall surfaces of the hoistway so as to extend vertically in two rows in the longitudinal direction of the building beam 11, and the guide rails are attached to the vertical columns 13 via the brackets. Be

このように、従来の立柱１３の据え付け方法では、耐火被覆材４の剥ぎ取り量が増大するので、耐火被覆材４の剥ぎ取り作業負荷および耐火被覆材４の再吹き付け作業負荷が増大し、立柱１３の敷設負荷が増大してしまう。   As described above, in the conventional method of installing the vertical column 13, since the removal amount of the fireproof covering material 4 is increased, the removal work load of the fireproof covering material 4 and the respraying work load of the fireproof covering material 4 are increased. The laying load of 13 will increase.

実施の形態１によれば、立柱１３を敷設するに先だって、立柱１３を取り付ける節点の近傍の耐火被覆材４のみを剥ぎ取るだけでよいので、耐火被覆材４の剥ぎ取り作業負荷および耐火被覆材４の再吹き付け作業負荷が軽減され、立柱１３の敷設負荷を大幅に軽減することができる。   According to the first embodiment, since it is only necessary to peel off the fireproof covering 4 in the vicinity of the node to which the standing pillar 13 is attached prior to laying the standing post 13, the work load for removing the fireproof covering 4 and the fireproof covering The re-blasting work load of No. 4 can be reduced, and the laying load of the upright 13 can be significantly reduced.

また、立柱１３が昇降路１内のデッドスペースである骨組構造体１００の四隅に敷設されているので、エレベータの機器との干渉を回避することができる。   Further, since the uprights 13 are laid at the four corners of the frame structure 100 which is a dead space in the hoistway 1, interference with the elevator equipment can be avoided.

なお、上記実施の形態１では、枠部材１０の節点が、一方の建築梁１１の端面を、他方の建築梁１１の端部の側面に突き合わせ、両者を溶接などにより剛接合して、構成されているが、枠部材の節点は、例えば、建築梁１１の端面を建築梁１１の長さ方向に対して４５°傾斜する傾斜面とし、建築梁１１の端面同士を突き合わせて、両者を溶接などにより剛接合して、構成されてもよい。   In the first embodiment, the nodal point of the frame member 10 abuts the end face of one building beam 11 to the side face of the end of the other building beam 11 and is rigidly joined by welding or the like. However, for example, the end points of the building beam 11 are inclined surfaces inclined 45 ° with respect to the length direction of the building beam 11, and the end faces of the building beam 11 are butted, and both are welded It may be configured to be rigidly connected by
