Description

この発明は、乗客コンベヤ（例えばエスカレータや動く歩道等）の主枠に関するものである。   The present invention relates to a main frame of a passenger conveyor (for example, an escalator or a moving sidewalk).

通常、乗客コンベヤの主枠は、互いに離れた一対の構造物にそれぞれ設けられた受け梁間に架けられて設置されている。主枠の両端部には、支持金具が固定されている。主枠は、支持金具を受け梁に載せた状態で受け梁間に架けられている。従って、支持金具には、乗客コンベヤの全荷重が加わることとなる。   In general, the main frame of the passenger conveyor is installed between receiving beams provided in a pair of structures separated from each other. Support metal fittings are fixed to both ends of the main frame. The main frame is spanned between the receiving beams in a state where the support fitting is placed on the receiving beams. Therefore, the full load of the passenger conveyor is applied to the support fitting.

また、乗客コンベヤでは、一方の支持金具のみが受け梁に固定され、他方の支持金具は受け梁に固定されずにそのまま載せられた状態で、主枠が設置されることがある。このような乗客コンベヤでは、例えば乗客の重みによる主枠のたわみや地震等が発生しても、他方の支持金具が受け梁に対してずれることにより、主枠と受け梁との間で大きな応力が生じることが防止される。   In the passenger conveyor, the main frame may be installed in a state in which only one support fitting is fixed to the receiving beam and the other support fitting is not fixed to the receiving beam but is placed as it is. In such a passenger conveyor, for example, even if a deflection of the main frame due to the weight of the passenger, an earthquake, or the like occurs, a large stress is generated between the main frame and the receiving beam because the other support bracket is displaced with respect to the receiving beam. Is prevented from occurring.

しかし、支持金具が受け梁から離れる方向へずれる場合には、支持金具の支持間距離が大きくなるので、支持金具が受ける曲げモーメントが増大する。従って、支持金具の破損や変形を防止するために、支持金具には高い強度が要求される。   However, when the support bracket is displaced away from the receiving beam, the distance between the support brackets is increased, and the bending moment received by the support bracket is increased. Therefore, in order to prevent breakage and deformation of the support bracket, the support bracket is required to have high strength.

従来、支持金具を補強するために、主枠端部の縦部材に固定された支持金具に補強板を重ねて溶接した乗客コンベヤの主枠が提案されている（例えば特許文献１参照）。   Conventionally, in order to reinforce a support metal fitting, a main frame of a passenger conveyor has been proposed in which a reinforcing plate is overlapped and welded to a support metal fitting fixed to a longitudinal member at the end of the main frame (see, for example, Patent Document 1).

また、従来、主枠の上弦材を主枠端部の縦部材から突出させるとともに、上弦材の突出部分の下面と縦部材とに断面Ｌ字状の支持金具を固定することにより、支持金具を補強した乗客コンベヤの主枠も提案されている（例えば特許文献１参照）。   Conventionally, the upper chord member of the main frame protrudes from the vertical member at the end of the main frame, and the support metal fitting is fixed by fixing the L-shaped support metal fitting to the lower surface and the vertical member of the protruding portion of the upper chord material. A main frame of a reinforced passenger conveyor has also been proposed (see, for example, Patent Document 1).

さらに、従来、主枠の端部の縦部材に複数の支持金具を固定するとともに、構造物に複数の受け梁を設け、各支持金具を各受け梁に個別に載せることにより、１つの支持金具に加わる荷重を低減するようにした乗客コンベヤの主枠も提案されている（例えば特許文献２参照）。   Further, conventionally, a plurality of support brackets are fixed to the vertical member at the end of the main frame, a plurality of support beams are provided on the structure, and each support bracket is individually mounted on each support beam, thereby providing one support bracket. A main frame of a passenger conveyor has also been proposed that reduces the load applied to the vehicle (see, for example, Patent Document 2).

特開平４−１７９６９１号公報Japanese Patent Laid-Open No. 4-179691 特開平４−１５９９９５号公報Japanese Patent Laid-Open No. 4-159995

しかし、支持金具に補強板を重ねて溶接した主枠では、支持金具の破損や変形は防止されるが、支持金具で受けた荷重が縦部材に集中することとなり、縦部材が曲がってしまうおそれがある。   However, in the main frame in which the reinforcing plate is welded to the support bracket, the support bracket is prevented from being damaged or deformed, but the load received by the support bracket is concentrated on the vertical member, and the vertical member may be bent. There is.

また、上弦材を縦部材よりも突出させた主枠では、上弦材を載せる位置に窪みを設ける必要があるので、上弦材の突出部分の位置やサイズに合わせて掘り込み工事を受け梁に行う必要がある。従って、主枠の設置に手間がかかってしまう。   Also, in the main frame in which the upper chord material protrudes from the vertical member, it is necessary to provide a recess at the position where the upper chord material is placed, so that the beam is subjected to excavation work according to the position and size of the protruding portion of the upper chord material There is a need. Therefore, it takes time to install the main frame.

さらに、主枠の端部の縦部材に複数の支持金具を固定した主枠でも、各支持金具を受け梁に個別に載せるために、各支持金具の位置に合わせて複数の受け梁を設ける掘り込み工事を行う必要があり、主枠の設置に手間がかかってしまう。   Furthermore, even in a main frame in which a plurality of support brackets are fixed to the vertical member at the end of the main frame, a plurality of support beams are provided in accordance with the positions of the support brackets so that each support bracket is individually placed on the support beam. It is necessary to perform complicated construction, and it takes time to install the main frame.

この発明は、上記のような課題を解決するためになされたものであり、強度の向上を図ることができるとともに、容易に設置することができる乗客コンベヤの主枠を得ることを目的とする。   The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain a main frame of a passenger conveyor that can be improved in strength and can be easily installed.

この発明に係る乗客コンベヤの主枠は、主枠本体と、主枠本体の長さ方向端部に設けられ、構造物の受け部に載せられる支持部材とを備えている乗客コンベヤの主枠であって、主枠本体は、支持部材が固定された縦部材と、支持部材が固定された縦部材に固定され、縦部材を補強する補強部材とを有し、補強部材は、支持部材が重なる縦部材の部分と支持部材から外れた縦部材の部分との境界に重なるように縦部材に固定されている。
また、この発明に係る乗客コンベヤの主枠は、主枠本体と、主枠本体の長さ方向端部に設けられ、構造物の受け部に載せられる支持部材とを備えている乗客コンベヤの主枠であって、主枠本体は、主枠本体の長さ方向端部を補強する補強部材を有し、補強部材は、主枠本体の一部及び支持部材間を繋いだ状態で主枠本体の一部及び支持部材に固定されている。 A main frame of a passenger conveyor according to the present invention is a main frame of a passenger conveyor provided with a main frame main body and a support member provided at a longitudinal end of the main frame main body and placed on a receiving portion of a structure. The main frame main body includes a vertical member to which the support member is fixed, and a reinforcing member that is fixed to the vertical member to which the support member is fixed and reinforces the vertical member, and the support member overlaps the support member. It is fixed to the vertical member so as to overlap the boundary between the vertical member portion and the vertical member portion removed from the support member.
A main frame of a passenger conveyor according to the present invention is a main frame of a passenger conveyor provided with a main frame main body and a support member provided at a longitudinal end of the main frame main body and placed on a receiving portion of a structure. The main frame main body has a reinforcing member that reinforces the longitudinal end of the main frame main body, and the reinforcing member is connected to a part of the main frame main body and the support member. Are fixed to a part of the support member and the support member.

この発明に係る乗客コンベヤの主枠では、支持部材が固定された縦部材に補強部材が固定され、補強部材は、支持部材が重なる縦部材の部分と支持部材から外れた縦部材の部分との境界に重なるように縦部材に固定されているので、縦部材に生じる応力の集中部分を効率良く補強することができ、主枠の強度の向上を効果的に図ることができる。また、縦部材が補強されるので、上弦材を縦部材から突出させたり、複数の支持部材を縦部材に固定したりする必要がなくなり、支持部材の厚さ寸法を大きくするだけで支持部材の形状をほとんど変更させずに支持部材の強度を向上させることができる。従って、主枠の設置の際に構造物の受け部に対して掘り込み工事等を行う必要がなくなり、主枠の設置を容易にすることができる。
また、補強部材は、主枠本体の一部及び支持部材間を繋いだ状態で主枠本体の一部及び支持部材に固定されているので、支持部材の形状をほとんど変更させずに支持部材の強度を向上させることができる。従って、主枠の設置の際に構造物の受け部に対して掘り込み工事等を行う必要がなくなり、主枠の設置を容易にすることができる。 In the main frame of the passenger conveyor according to the present invention, the reinforcing member is fixed to the vertical member to which the supporting member is fixed. Since it is fixed to the vertical member so as to overlap the boundary, the concentrated portion of stress generated in the vertical member can be reinforced efficiently, and the strength of the main frame can be effectively improved. In addition, since the vertical member is reinforced, it is not necessary to project the upper chord material from the vertical member or to fix the plurality of support members to the vertical member, and by simply increasing the thickness dimension of the support member, The strength of the support member can be improved with almost no change in shape. Therefore, it is not necessary to perform digging work or the like on the receiving portion of the structure when installing the main frame, and the main frame can be easily installed.
Further, since the reinforcing member is fixed to a part of the main frame body and the support member in a state where the part of the main frame body and the support member are connected to each other, the shape of the support member is hardly changed. Strength can be improved. Therefore, it is not necessary to perform digging work or the like on the receiving portion of the structure when installing the main frame, and the main frame can be easily installed.

下弦材９、上弦材１０、下部縦部材１１、上部縦部材１２、中間縦部材１３及び主枠下部材１４のそれぞれは、断面Ｌ字形の棒状部材とされている。また、下弦材９、上弦材１０、下部縦部材１１、上部縦部材１２、中間縦部材１３及び主枠下部材１４は、互いに溶接により固定されている。   Each of the lower chord member 9, the upper chord member 10, the lower vertical member 11, the upper vertical member 12, the intermediate vertical member 13, and the main frame lower member 14 is a rod-shaped member having an L-shaped cross section. The lower chord member 9, the upper chord member 10, the lower vertical member 11, the upper vertical member 12, the intermediate vertical member 13, and the main frame lower member 14 are fixed to each other by welding.

下部縦部材１１は、主枠本体４の長さ方向下端部に配置され、かつ主枠本体４の幅方向両端部にそれぞれ配置されている。上部縦部材１２は、主枠本体４の長さ方向上端部に配置され、かつ主枠本体４の幅方向両端部にそれぞれ配置されている。下部縦部材１１及び上部縦部材１２は、それぞれ上下方向に沿って配置されている。   The lower vertical member 11 is disposed at the lower end in the length direction of the main frame body 4 and is disposed at both ends in the width direction of the main frame body 4. The upper vertical member 12 is disposed at the upper end in the length direction of the main frame body 4 and is disposed at both ends in the width direction of the main frame body 4. The lower vertical member 11 and the upper vertical member 12 are arranged along the vertical direction.

上部支持金具６は、図２及び図３に示すように、左右の上部縦部材１２の上部間に溶接により固定されている。また、上部支持金具６は、主枠本体４の幅方向に沿って配置されている。さらに、上部支持金具６は、上部縦部材１２に当てられた縦板部６ａと、縦板部６ａから上部構造物２側へ突出する横板部６ｂとを有している。上部支持金具６の断面形状は、縦板部６ａ及び横板部６ｂによってＬ字形になっている。   As shown in FIGS. 2 and 3, the upper support fitting 6 is fixed between the upper portions of the left and right upper vertical members 12 by welding. Further, the upper support fitting 6 is disposed along the width direction of the main frame body 4. Further, the upper support metal fitting 6 has a vertical plate portion 6a applied to the upper vertical member 12, and a horizontal plate portion 6b protruding from the vertical plate portion 6a to the upper structure 2 side. The cross-sectional shape of the upper support fitting 6 is L-shaped by the vertical plate portion 6a and the horizontal plate portion 6b.

上部支持金具６は、上部縦部材１２の上部構造物２側の面（即ち、上部縦部材１２の外面）に縦板部６ａを重ねた状態で上部縦部材１２の上部に固定されている。横板部６ｂは、複数（この例では、２つ）の支持板８を介して上部構造物２の受け梁に載せられている。各支持板８は、互いに離して配置されている。   The upper support bracket 6 is fixed to the upper portion of the upper vertical member 12 in a state where the vertical plate portion 6a is superimposed on the surface of the upper vertical member 12 on the upper structure 2 side (that is, the outer surface of the upper vertical member 12). The horizontal plate portion 6b is placed on the receiving beam of the upper structure 2 via a plurality of (two in this example) support plates 8. Each support plate 8 is arranged away from each other.

縦板部６ａ及び横板部６ｂのそれぞれの厚さ寸法は、上部支持金具６が乗客コンベヤの荷重を支持可能な強度を持つように所定の大きさに設定されている。即ち、上部支持金具６は、縦板部６ａ及び横板部６ｂのそれぞれの厚さ寸法を所定の大きさにすることにより、乗客コンベヤの荷重を支える強度を確保している。   The thickness dimension of each of the vertical plate portion 6a and the horizontal plate portion 6b is set to a predetermined size so that the upper support fitting 6 has a strength capable of supporting the load of the passenger conveyor. That is, the upper support fitting 6 secures the strength to support the load of the passenger conveyor by making the thickness dimensions of the vertical plate portion 6a and the horizontal plate portion 6b a predetermined size.

In this example, the reinforcing member 15 is a rectangular plate. Further, the side portion of the reinforcing member 15 is overlaid on the back surface of the upper vertical member 12 (that is, the surface opposite to the outer surface of the upper vertical member 12 to which the upper support metal fitting 6 is fixed). Of the back surface of the upper vertical member 12, the range in which the reinforcing member 15 overlaps is as follows from the portion of the upper vertical member 12 where the vertical plate portion 6a overlaps, to the vertical plate portion 6a and the main frame lower member 14, respectively, as shown in FIG. The portion of the upper vertical member 12 that is separated from the upper vertical member 12 reaches the portion of the upper vertical member 12 where the main frame lower member 14 overlaps. As a result, the side portion of the reinforcing member 15 overlaps the boundary between the portion of the upper vertical member 12 where the vertical plate portion 6a overlaps and the portion of the upper vertical member 12 removed from the vertical plate portion 6a, and the main frame lower member 14 It also overlaps the boundary between the overlapping upper vertical member 12 portion and the upper vertical member 12 portion removed from the main frame lower member 14. The reinforcing member 15 is fixed to the upper vertical member 12 in a state where the side portion is overlapped with the back surface of the upper vertical member 12.

The vertical plate portion 6 a is provided with a plurality of bolt through holes 17 spaced from each other in the length direction of the upper support fitting 6. The main frame lower member 14 is provided with a plurality of bolt through holes 18 spaced from each other in the length direction of the main frame lower member 14. The reinforcing member 15 is provided with a plurality of bolt through holes 19 corresponding to the positions of the bolt through holes 16, 17 and 18.

縦板部６ａ、上部縦部材１２及び主枠下部材１４のそれぞれに対する補強部材１５の固定は、ボルト及びナットを有する締結具２０により行われている。補強部材１５は、各ボルト通し穴１６，１９に通されたボルトにナットが締め付けられることにより上部縦部材１２に固定され、各ボルト通し穴１７，１９に通されたボルトにナットが締め付けられることにより縦板部６ａに固定され、各ボルト通し穴１８，１９に通されたボルトにナットが締め付けられることにより主枠下部材１４に固定されている。   Fixing of the reinforcing member 15 to each of the vertical plate portion 6a, the upper vertical member 12, and the main frame lower member 14 is performed by a fastener 20 having bolts and nuts. The reinforcing member 15 is fixed to the upper vertical member 12 by tightening nuts to bolts passed through the bolt through holes 16 and 19, and nuts are tightened to bolts passed through the bolt through holes 17 and 19. Is fixed to the main plate lower member 14 by being fastened to the vertical plate portion 6a and by tightening nuts to the bolts passed through the respective bolt through holes 18 and 19.

上部支持金具６は、図３に示すように、主枠本体４の幅方向について、各補強部材１５が固定された一対の補強区間Ａと、各補強区間Ａ間に位置する中間区間Ｂとに区分されている。支持板８は、補強区間Ａ内に配置されている。この例では、支持板８は、補強区間Ａ内の中間区間Ｂに接する位置に配置されている。   As shown in FIG. 3, the upper support fitting 6 is divided into a pair of reinforcing sections A to which the reinforcing members 15 are fixed and an intermediate section B located between the reinforcing sections A in the width direction of the main frame body 4. It is divided. The support plate 8 is disposed in the reinforcing section A. In this example, the support plate 8 is disposed at a position in contact with the intermediate section B in the reinforcing section A.

ここで、主枠本体４から補強部材１５を外した状態で主枠３の応力分布の解析を構造解析技術を用いて行った。図４は、補強部材１５を外した主枠３の長さ方向上端部において応力が集中する範囲を示す側面図である。また、図５は図４の主枠３の長さ方向上端部を示す正面図、図６は図５の主枠３の長さ方向上端部を示す上面図である。図４〜図６に示すように、応力が集中する範囲は、横板部６ｂの根元の範囲Ｃ、及び上部縦部材１２の縦板部６ａに隣接する範囲Ｄであることが分かる。   Here, the analysis of the stress distribution of the main frame 3 was performed using a structure analysis technique in a state where the reinforcing member 15 was removed from the main frame body 4. FIG. 4 is a side view showing a range in which stress is concentrated at the upper end in the length direction of the main frame 3 with the reinforcing member 15 removed. 5 is a front view showing the upper end portion in the length direction of the main frame 3 in FIG. 4, and FIG. 6 is a top view showing the upper end portion in the length direction of the main frame 3 in FIG. As shown in FIGS. 4 to 6, it can be seen that the stress concentration range is a range C at the base of the horizontal plate portion 6 b and a range D adjacent to the vertical plate portion 6 a of the upper vertical member 12.

横板部６ｂの根元の範囲Ｃにおいては、縦板部６ａ及び横板部６ｂのそれぞれの厚さ寸法が所定の大きさに設定されていることにより、断面係数が調整され、応力が許容値以下に下げられている。上部縦部材１２の縦板部６ａに隣接する範囲Ｄにおいては、上部縦部材１２に補強部材１５が固定されることにより、上部縦部材１２の荷重が補強部材１５に分散され、応力が許容値以下に下げられる。   In the range C at the base of the horizontal plate portion 6b, the thickness of each of the vertical plate portion 6a and the horizontal plate portion 6b is set to a predetermined size, so that the section modulus is adjusted and the stress is allowed. Has been lowered to: In the range D adjacent to the vertical plate portion 6a of the upper vertical member 12, the load of the upper vertical member 12 is distributed to the reinforcing member 15 by fixing the reinforcing member 15 to the upper vertical member 12, and the stress is allowed. Lowered to:

下部支持金具５の構成は、上部支持金具６と同様の構成である。また、主枠本体４の長さ方向下端部の構成についても、主枠本体４の長さ方向上端部の構成と同様である。   The configuration of the lower support bracket 5 is the same as that of the upper support bracket 6. The configuration of the lower end portion in the length direction of the main frame main body 4 is the same as the configuration of the upper end portion in the length direction of the main frame main body 4.

このようなエスカレータの主枠３では、上部支持金具６が固定された上部縦部材１２に補強部材１５が固定され、補強部材１５は、上部支持金具６が重なる上部縦部材１２の部分と上部支持金具６から外れた上部縦部材１２の部分との境界に重なるように上部縦部材１２に固定されているので、上部縦部材１２に生じる応力の集中部分を効率良く補強することができ、主枠３の強度の向上を効果的に図ることができる。また、上部縦部材１２が補強されるので、上弦材を縦部材から突出させたり、複数の支持金具を縦部材に固定したりする必要がなくなり、上部支持金具６の厚さ寸法を大きくするだけで上部支持金具６の形状をほとんど変更させずに上部支持金具６の強度を向上させることができる。従って、主枠３の設置の際に上部構造物２の受け梁に対して掘り込み工事等を行う必要がなくなり、主枠３の設置を容易にすることができる。さらに、補強部材１５を主枠本体４に追加するだけで、主枠３の構造が従来とほとんど変わらないので、主枠３の構成部材や製造手順等の大幅な変更を避けることができる。従って、主枠３の製造や改修も容易にすることができる。
また、下部支持金具５が固定された下部縦部材１１にも補強部材が固定されているので、主枠本体４の長さ方向下端部においても、同様の効果を得ることができる。 In the main frame 3 of such an escalator, the reinforcing member 15 is fixed to the upper vertical member 12 to which the upper support bracket 6 is fixed, and the reinforcement member 15 includes the portion of the upper vertical member 12 on which the upper support bracket 6 overlaps and the upper support member. Since it is fixed to the upper vertical member 12 so as to overlap the boundary with the portion of the upper vertical member 12 removed from the metal fitting 6, the concentrated portion of stress generated in the upper vertical member 12 can be efficiently reinforced, and the main frame 3 can be effectively improved. Further, since the upper vertical member 12 is reinforced, it is not necessary to project the upper chord material from the vertical member or to fix the plurality of support brackets to the vertical member, and only to increase the thickness dimension of the upper support bracket 6. Thus, the strength of the upper support fitting 6 can be improved without substantially changing the shape of the upper support fitting 6. Therefore, it is not necessary to perform digging work or the like on the receiving beam of the upper structure 2 when the main frame 3 is installed, and the main frame 3 can be easily installed. Furthermore, since the structure of the main frame 3 is almost the same as that of the prior art only by adding the reinforcing member 15 to the main frame main body 4, it is possible to avoid significant changes in the constituent members and manufacturing procedures of the main frame 3. Accordingly, the manufacture and repair of the main frame 3 can be facilitated.
Further, since the reinforcing member is also fixed to the lower vertical member 11 to which the lower support metal fitting 5 is fixed, the same effect can be obtained at the lower end in the length direction of the main frame body 4.

また、補強部材１５は、上部縦部材１２とともに、上部支持金具６にも固定されているので、上部縦部材１２が受ける荷重をさらに分散させることができ、主枠３の強度の向上をさらに図ることができる。
下部縦部材１１に固定された補強部材も下部支持金具５に固定されているので、主枠本体４の長さ方向下端部においても、同様の効果を得ることができる。 In addition, since the reinforcing member 15 is fixed to the upper support member 6 together with the upper vertical member 12, the load received by the upper vertical member 12 can be further dispersed, and the strength of the main frame 3 is further improved. be able to.
Since the reinforcing member fixed to the lower vertical member 11 is also fixed to the lower support fitting 5, the same effect can be obtained at the lower end in the length direction of the main frame body 4.

なお、上記の例では、補強部材１５が上部縦部材１２、上部支持金具６及び主枠下部材１４のそれぞれに締結具２０によって固定されているが、上部縦部材１２、上部支持金具６及び主枠下部材１４のそれぞれに補強部材１５を溶接によって固定してもよい。主枠本体４の長さ方向下端部においても同様に、下部縦部材１１、下部支持金具５及び主枠下部材のそれぞれに補強部材を溶接によって固定してもよい。   In the above example, the reinforcing member 15 is fixed to the upper vertical member 12, the upper support bracket 6, and the main frame lower member 14 by the fastener 20, but the upper vertical member 12, the upper support bracket 6, and the main support bracket 6 and the main frame lower member 14 are fixed. The reinforcing member 15 may be fixed to each of the frame lower members 14 by welding. Similarly, a reinforcing member may be fixed to each of the lower vertical member 11, the lower support fitting 5, and the main frame lower member by welding at the lower end in the length direction of the main frame body 4.

実施の形態２．
実施の形態１では、補強部材１５が矩形状の板とされているが、補強部材１５を三角形状の板としてもよい。 Embodiment 2. FIG.
Although the reinforcing member 15 is a rectangular plate in the first embodiment, the reinforcing member 15 may be a triangular plate.

即ち、図７は、この発明の実施の形態２によるエスカレータの主枠の長さ方向上端部を示す正面図である。なお、図７は、実施の形態１の図３に対応する図である。図において、各補強部材１５は、三角形状の板とされている。また、補強部材１５は、上部縦部材１２、上部支持金具６の縦板部６ａ及び主枠下部材１４のうち、上部縦部材１２及び縦板部６ａのみに固定されている。即ち、補強部材１５は、主枠下部材１４には固定されずに、主枠下部材１４から離して配置されている。主枠本体４の長さ方向下端部の構成についても、主枠本体４の長さ方向上端部の構成と同様である。また、他の構成は実施の形態１と同様である。   That is, FIG. 7 is a front view showing the upper end in the length direction of the main frame of the escalator according to Embodiment 2 of the present invention. FIG. 7 is a diagram corresponding to FIG. 3 of the first embodiment. In the figure, each reinforcing member 15 is a triangular plate. The reinforcing member 15 is fixed only to the upper vertical member 12 and the vertical plate portion 6 a among the upper vertical member 12, the vertical plate portion 6 a of the upper support metal 6 and the main frame lower member 14. That is, the reinforcing member 15 is not fixed to the main frame lower member 14 but is arranged away from the main frame lower member 14. The configuration of the lower end portion in the length direction of the main frame main body 4 is the same as the configuration of the upper end portion in the length direction of the main frame main body 4. Other configurations are the same as those in the first embodiment.

このように、補強部材１５を三角形状の板とし、補強部材１５を主枠下部材１４から離して配置するようにしても、上部縦部材１２を補強することができ、主枠３の強度の向上を図ることができる。また、上部縦部材１２が補強されるので、上部支持金具６の形状をほとんど変更させずに上部支持金具６の強度を向上させることができ、主枠３の設置を容易にすることができる。さらに、補強部材１５の材料を削減することができ、コストの低減化も図ることができる。
また、主枠本体４の長さ方向下端部においても、同様の効果を得ることができる。 Thus, even if the reinforcing member 15 is a triangular plate and the reinforcing member 15 is arranged away from the main frame lower member 14, the upper vertical member 12 can be reinforced, and the strength of the main frame 3 can be increased. Improvements can be made. Moreover, since the upper vertical member 12 is reinforced, the strength of the upper support fitting 6 can be improved without changing the shape of the upper support fitting 6 and the installation of the main frame 3 can be facilitated. Furthermore, the material of the reinforcing member 15 can be reduced, and the cost can be reduced.
The same effect can also be obtained at the lower end of the main frame body 4 in the length direction.

なお、上記の例では、補強部材１５が上部縦部材１２及び上部支持金具６のそれぞれに締結具２０によって固定されているが、上部縦部材１２及び上部支持金具６のそれぞれに補強部材１５を溶接によって固定してもよい。主枠本体４の長さ方向下端部においても同様に、下部縦部材１１及び下部支持金具５のそれぞれに補強部材を溶接によって固定してもよい。   In the above example, the reinforcing member 15 is fixed to the upper vertical member 12 and the upper support bracket 6 by the fastener 20, but the reinforcing member 15 is welded to the upper vertical member 12 and the upper support bracket 6. It may be fixed by. Similarly, a reinforcing member may be fixed to each of the lower vertical member 11 and the lower support fitting 5 by welding at the lower end in the length direction of the main frame body 4.

実施の形態３．
実施の形態１では、縦部材の支持金具に重なる部分に補強部材１５の一部が重なった状態で、補強部材１５が支持金具、縦部材及び主枠下部材に固定されているが、縦部材の支持金具に重なる部分に重ねずに補強部材１５を支持金具及び主枠下部材に固定してもよい。 Embodiment 3 FIG.
In the first embodiment, the reinforcing member 15 is fixed to the supporting bracket, the vertical member, and the main frame lower member in a state where a part of the reinforcing member 15 overlaps the portion of the vertical member that overlaps the supporting bracket. The reinforcing member 15 may be fixed to the support bracket and the main frame lower member without overlapping the portion overlapping the support bracket.

即ち、図８は、この発明の実施の形態３によるエスカレータの主枠の長さ方向上端部を示す正面図である。なお、図８は、実施の形態１の図３に対応する図である。各上部縦部材１２のそれぞれの上端部は、主枠本体４の長さ方向に沿って見たとき、上部支持金具６の両端部に重なっている。各補強部材１５は、上部縦部材１２の上部支持金具６に重なる部分から離して配置されている。また、各補強部材１５は、上部支持金具６及び上部縦部材（主枠本体４の一部）１２間を繋いだ状態で上部支持金具６及び上部縦部材１２に固定されている。各補強部材１５は、主枠下部材１４に固定されずに、主枠下部材１４から離して配置されている。   That is, FIG. 8 is a front view showing the upper end in the length direction of the main frame of the escalator according to Embodiment 3 of the present invention. FIG. 8 corresponds to FIG. 3 of the first embodiment. Each upper end of each upper vertical member 12 overlaps both ends of the upper support fitting 6 when viewed along the length direction of the main frame body 4. Each reinforcing member 15 is arranged away from a portion of the upper vertical member 12 that overlaps the upper support fitting 6. Each reinforcing member 15 is fixed to the upper support member 6 and the upper vertical member 12 in a state where the upper support member 6 and the upper vertical member (a part of the main frame body 4) 12 are connected. Each reinforcing member 15 is not fixed to the main frame lower member 14 but is arranged away from the main frame lower member 14.

補強部材１５としては、例えば平板、チャネル部材、Ｈ形部材、Ｌ形部材又は中空部材等、長さを持つ部材が用いられている。補強部材１５の一端部は上部支持金具６の中間部に締結具２０で固定され、補強部材１５の他端部は上部縦部材１２の中間部に締結具２０で固定されている。これにより、各補強部材１５は、上部支持金具６及び上部縦部材１２のそれぞれに対して傾斜して配置され、上部支持金具６及び上部縦部材１２間に筋交いとして固定されている。この例では、左右の上部縦部材１２のそれぞれと上部支持金具６との間に補強部材１５が１本ずつ固定されている。   As the reinforcing member 15, a member having a length such as a flat plate, a channel member, an H-shaped member, an L-shaped member, or a hollow member is used. One end of the reinforcing member 15 is fixed to the intermediate portion of the upper support fitting 6 with a fastener 20, and the other end of the reinforcing member 15 is fixed to the intermediate portion of the upper vertical member 12 with the fastener 20. Accordingly, each reinforcing member 15 is disposed to be inclined with respect to each of the upper support fitting 6 and the upper vertical member 12, and is fixed as a brace between the upper support fitting 6 and the upper vertical member 12. In this example, one reinforcing member 15 is fixed between each of the left and right upper vertical members 12 and the upper support fitting 6.

主枠本体４の長さ方向下端部に設けられる補強部材の構成についても、主枠本体４の長さ方向上端部に設けられる補強部材１５の構成と同様である。他の構成は実施の形態１と同様である。   The configuration of the reinforcing member provided at the lower end portion in the length direction of the main frame main body 4 is the same as the configuration of the reinforcing member 15 provided at the upper end portion in the length direction of the main frame main body 4. Other configurations are the same as those in the first embodiment.

このようなエスカレータの主枠３では、補強部材１５が、上部縦部材１２の上部支持金具６に重なる部分から離して配置された状態で、上部支持金具６及び上部縦部材１２に固定されているので、各上部縦部材１２及び上部支持金具６間に補強部材１５を筋交いとして固定することができる。これにより、上部支持金具６及び上部縦部材１２を補強しながら補強部材１５の材料を削減することができ、コストの低減化をさらに図ることができる。また、上部支持金具６の形状をほとんど変更させずに上部支持金具６の強度を向上させることができるので、主枠３の設置の際に上部構造物２の受け梁に対して掘り込み工事等を行う必要がなくなり、主枠３の設置を容易にすることができる。さらに、標準品の主枠３に補強部材１５を追加するだけで主枠３の補強をすることができるので、主枠３の構成部材や製造手順等の大幅な変更を避けることができ、主枠３の製造や改修も容易にすることができる。
また、主枠本体４の長さ方向下端部においても、同様の効果を得ることができる。 In the main frame 3 of such an escalator, the reinforcing member 15 is fixed to the upper support member 6 and the upper vertical member 12 in a state where the reinforcing member 15 is arranged away from the portion overlapping the upper support member 6 of the upper vertical member 12. Therefore, the reinforcing member 15 can be fixed as a brace between the upper vertical members 12 and the upper support fitting 6. Thereby, the material of the reinforcing member 15 can be reduced while reinforcing the upper support fitting 6 and the upper vertical member 12, and the cost can be further reduced. Further, the strength of the upper support bracket 6 can be improved without changing the shape of the upper support bracket 6, so that when the main frame 3 is installed, excavation work or the like is performed on the receiving beam of the upper structure 2. There is no need to perform the operation, and the installation of the main frame 3 can be facilitated. Furthermore, since the main frame 3 can be reinforced simply by adding the reinforcing member 15 to the standard main frame 3, it is possible to avoid major changes in the components and manufacturing procedures of the main frame 3, Manufacture and repair of the frame 3 can also be facilitated.
The same effect can also be obtained at the lower end of the main frame body 4 in the length direction.

なお、上記の例では、各上部縦部材１２のそれぞれと上部支持金具６との間に補強部材１５が左右１本ずつ固定されているが、各上部縦部材１２のそれぞれと上部支持金具６との間に補強部材１５を左右複数本ずつ並べて固定してもよい。主枠本体４の長さ方向下端部においても同様に、各下部縦部材１１のそれぞれと下部支持金具５との間に補強部材を左右複数本ずつ並べて固定してもよい。この場合、各補強部材は互いに離して並べてもよいし、互いに接触させて並べてもよい。また、接触させて並べた複数本の補強部材を溶接等により一体化してもよい。   In the above example, one reinforcing member 15 is fixed between each of the upper vertical members 12 and the upper support bracket 6. However, each of the upper vertical members 12, the upper support bracket 6, A plurality of reinforcing members 15 may be arranged side by side and fixed between them. Similarly, at the lower end in the length direction of the main frame main body 4, a plurality of reinforcing members may be arranged side by side between the lower vertical members 11 and the lower support bracket 5. In this case, the reinforcing members may be arranged apart from each other or arranged in contact with each other. A plurality of reinforcing members arranged in contact with each other may be integrated by welding or the like.

また、上記の例では、補強部材１５が上部縦部材１２及び上部支持金具６のそれぞれに締結具２０で固定されているが、上部縦部材１２及び上部支持金具６のそれぞれに補強部材１５を溶接によって固定してもよい。主枠本体４の長さ方向下端部においても同様に、下部縦部材１１及び下部支持金具５のそれぞれに補強部材を溶接によって固定してもよい。   In the above example, the reinforcing member 15 is fixed to the upper vertical member 12 and the upper support bracket 6 with the fastener 20, but the reinforcing member 15 is welded to each of the upper vertical member 12 and the upper support bracket 6. It may be fixed by. Similarly, a reinforcing member may be fixed to each of the lower vertical member 11 and the lower support fitting 5 by welding at the lower end in the length direction of the main frame body 4.

実施の形態４．
実施の形態３では、補強部材１５が、主枠下部材に固定されずに支持金具及び縦部材に固定されているが、補強部材１５を、縦部材に固定せずに支持金具及び主枠下部材に固定するようにしてもよい。 Embodiment 4 FIG.
In Embodiment 3, the reinforcing member 15 is fixed to the support bracket and the vertical member without being fixed to the main frame lower member. However, the reinforcing member 15 is not fixed to the vertical member and is fixed to the support bracket and the main frame. You may make it fix to a member.

即ち、図９は、この発明の実施の形態４によるエスカレータの主枠の長さ方向上端部を示す正面図である。なお、図９は、実施の形態１の図３に対応する図である。各補強部材１５は、上部縦部材１２の上部支持金具６に重なる部分から離して配置されている。また、各補強部材１５は、上部支持金具６及び主枠下部材（主枠本体４の一部）１４間を繋いだ状態で上部支持金具６及び主枠下部材１４に固定されている。さらに、各補強部材１５は、上部縦部材１２に固定されずに、上部縦部材１２から離して配置されている。   That is, FIG. 9 is a front view showing the upper end in the length direction of the main frame of the escalator according to Embodiment 4 of the present invention. FIG. 9 is a diagram corresponding to FIG. 3 of the first embodiment. Each reinforcing member 15 is arranged away from a portion of the upper vertical member 12 that overlaps the upper support fitting 6. Each reinforcing member 15 is fixed to the upper support bracket 6 and the main frame lower member 14 in a state where the upper support bracket 6 and the main frame lower member (a part of the main frame main body 4) 14 are connected. Further, each reinforcing member 15 is not fixed to the upper vertical member 12 but is arranged away from the upper vertical member 12.

補強部材１５は、実施の形態３と同様の部材である。補強部材１５の一端部は上部支持金具５の中間部に締結具２０で固定され、補強部材１５の他端部は主枠下部材１４の中間部に締結具２０で固定されている。これにより、各補強部材１５は、上部縦部材１２と平行に上下に沿って配置され、上部支持金具５及び主枠下部材１４間に固定されている。この例では、上部支持金具６及び主枠下部材１４間に補強部材１５が左右１本ずつ互いに離して固定されている。   The reinforcing member 15 is the same member as in the third embodiment. One end portion of the reinforcing member 15 is fixed to the intermediate portion of the upper support fitting 5 with the fastener 20, and the other end portion of the reinforcing member 15 is fixed to the intermediate portion of the main frame lower member 14 with the fastener 20. Thereby, each reinforcing member 15 is arranged along the upper and lower sides in parallel with the upper vertical member 12, and is fixed between the upper support fitting 5 and the main frame lower member 14. In this example, the reinforcing members 15 are fixed apart from each other on the left and right sides between the upper support fitting 6 and the main frame lower member 14.

主枠本体４の長さ方向下端部に設けられる補強部材の構成についても、主枠本体４の長さ方向上端部に設けられる補強部材１５の構成と同様である。他の構成は実施の形態３と同様である。   The configuration of the reinforcing member provided at the lower end portion in the length direction of the main frame main body 4 is the same as the configuration of the reinforcing member 15 provided at the upper end portion in the length direction of the main frame main body 4. Other configurations are the same as those of the third embodiment.

このように、上部縦部材１２から離して配置した状態で上部支持金具６及び主枠下部材１４間に補強部材１５を固定するようにしても、上部支持金具６を補強しながら補強部材１５の材料を削減することができ、コストの低減化をさらに図ることができる。
また、主枠本体４の長さ方向下端部においても、同様の効果を得ることができる。 As described above, even if the reinforcing member 15 is fixed between the upper support bracket 6 and the main frame lower member 14 in a state of being arranged away from the upper vertical member 12, the reinforcement member 15 is reinforced while reinforcing the upper support bracket 6. The material can be reduced, and the cost can be further reduced.
The same effect can also be obtained at the lower end of the main frame body 4 in the length direction.

なお、上記の例では、上部支持金具６及び主枠下部材１４間に補強部材１５が左右１本ずつ固定されているが、上部支持金具６及び主枠下部材１４間に３本以上の補強部材１５を並べて固定してもよい。主枠本体４の長さ方向下端部においても同様に、下部支持金具５及び主枠下部材１４間に３本以上の補強部材を並べて固定してもよい。この場合、各補強部材は互いに離して並べてもよいし、互いに接触させて並べてもよい。また、接触させて並べた複数本の補強部材を溶接等により一体化してもよい。   In the above example, one reinforcing member 15 is fixed between the upper support fitting 6 and the main frame lower member 14, but one or more reinforcement members 15 are fixed between the upper support fitting 6 and the main frame lower member 14. The members 15 may be fixed side by side. Similarly, at the lower end of the main frame body 4 in the length direction, three or more reinforcing members may be arranged and fixed between the lower support bracket 5 and the main frame lower member 14. In this case, the reinforcing members may be arranged apart from each other or arranged in contact with each other. A plurality of reinforcing members arranged in contact with each other may be integrated by welding or the like.

また、上記の例では、補強部材１５が上部支持金具６及び主枠下部材１４のそれぞれに締結具２０で固定されているが、上部支持金具６及び主枠下部材１４のそれぞれに補強部材１５を溶接によって固定してもよい。主枠本体４の長さ方向下端部においても同様に、下部支持金具５及び主枠下部材１４のそれぞれに補強部材を溶接によって固定してもよい。   In the above example, the reinforcing member 15 is fixed to each of the upper support bracket 6 and the main frame lower member 14 with the fastener 20, but the reinforcement member 15 is fixed to each of the upper support bracket 6 and the main frame lower member 14. May be fixed by welding. Similarly, at the lower end of the main frame body 4 in the length direction, a reinforcing member may be fixed to each of the lower support fitting 5 and the main frame lower member 14 by welding.

また、実施の形態４の補強部材１５を実施の形態３の補強部材１５と組み合わせて主枠本体４に設けてもよい。   Further, the reinforcing member 15 of the fourth embodiment may be provided in the main frame body 4 in combination with the reinforcing member 15 of the third embodiment.

実施の形態５．
実施の形態１では、補強部材１５が左右一対の縦部材に個別に１枚ずつ固定されているが、共通の１枚の補強部材１５を左右一対の縦部材、支持金具及び主枠下部材に固定してもよい。 Embodiment 5 FIG.
In the first embodiment, the reinforcing members 15 are individually fixed to the pair of left and right vertical members one by one, but the common reinforcing member 15 is used as the pair of left and right vertical members, the support bracket, and the main frame lower member. It may be fixed.

即ち、図１０は、この発明の実施の形態５によるエスカレータの主枠の長さ方向上端部を示す正面図である。なお、図１０は、実施の形態１の図３に対応する図である。主枠本体４の長さ方向上端部には、共通の１枚の補強部材１５が固定されている。補強部材１５は、左右一対の上部縦部材１２、上部支持金具６及び主枠下部材１４で構成された枠の形状に合わせて形成された矩形状の板とされている。各上部縦部材１２、上部支持金具６及び主枠下部材１４で構成された枠には、補強部材１５の外周部が補強部材１５の全周にわたって重なっている。これにより、補強部材１５は、各上部縦部材１２、上部支持金具６及び主枠下部材１４で囲まれた空間を塞いでいる。補強部材１５は、補強部材１５の全周にわたって互いに間隔を置いて配置された複数の締結具２０により、各上部縦部材１２、上部支持金具６及び主枠下部材１４のそれぞれに固定されている。   That is, FIG. 10 is a front view showing the upper end in the length direction of the main frame of the escalator according to the fifth embodiment of the present invention. FIG. 10 is a diagram corresponding to FIG. 3 of the first embodiment. A common reinforcing member 15 is fixed to the upper end of the main frame body 4 in the length direction. The reinforcing member 15 is a rectangular plate formed in accordance with the shape of the frame formed by the pair of left and right upper vertical members 12, the upper support bracket 6 and the main frame lower member 14. The outer peripheral portion of the reinforcing member 15 overlaps the entire circumference of the reinforcing member 15 in the frame formed by the upper vertical members 12, the upper support fitting 6 and the main frame lower member 14. As a result, the reinforcing member 15 closes the space surrounded by the upper vertical members 12, the upper support fitting 6, and the main frame lower member 14. The reinforcing member 15 is fixed to each of the upper vertical member 12, the upper support bracket 6, and the main frame lower member 14 by a plurality of fasteners 20 arranged at intervals from each other around the entire circumference of the reinforcing member 15. .

主枠本体４の長さ方向下端部に設けられる補強部材の構成についても、主枠本体４の長さ方向上端部に設けられる補強部材１５の構成と同様である。他の構成は実施の形態１と同様である。   The configuration of the reinforcing member provided at the lower end portion in the length direction of the main frame main body 4 is the same as the configuration of the reinforcing member 15 provided at the upper end portion in the length direction of the main frame main body 4. Other configurations are the same as those in the first embodiment.

このように、補強部材１５を共通の１枚の板とし、各上部縦部材１２、上部支持金具６及び主枠下部材１４のそれぞれに補強部材１５の外周部を補強部材１５の全周に亘って固定しているので、主枠３の強度の向上をさらに効果的に図ることができる。また、主枠本体４に固定する補強部材１５の数を減らすことができるので、補強部材１５の加工作業や固定作業を容易にすることができる。
また、主枠本体４の長さ方向下端部においても、同様の効果を得ることができる。 In this way, the reinforcing member 15 is a common plate, and the outer peripheral portion of the reinforcing member 15 extends over the entire circumference of the reinforcing member 15 in each of the upper vertical member 12, the upper support bracket 6, and the main frame lower member 14. Therefore, the strength of the main frame 3 can be improved more effectively. Moreover, since the number of the reinforcing members 15 fixed to the main frame main body 4 can be reduced, the processing operation and the fixing operation of the reinforcing members 15 can be facilitated.
The same effect can also be obtained at the lower end of the main frame body 4 in the length direction.

なお、上記の例では、補強部材１５が各上部縦部材１２、上部支持金具６及び主枠下部材１４のそれぞれに締結具２０で固定されているが、各上部縦部材１２、上部支持金具６及び主枠下部材１４のそれぞれに補強部材１５を溶接によって固定してもよい。主枠本体４の長さ方向下端部においても同様に、各下部縦部材１１、下部支持金具５及び主枠下部材１４のそれぞれに補強部材を溶接によって固定してもよい。   In the above example, the reinforcing member 15 is fixed to each of the upper vertical members 12, the upper support bracket 6 and the main frame lower member 14 with the fasteners 20, but each of the upper vertical members 12, the upper support bracket 6 is fixed. The reinforcing member 15 may be fixed to each of the main frame lower member 14 by welding. Similarly, a reinforcing member may be fixed to each of the lower vertical member 11, the lower support bracket 5, and the main frame lower member 14 by welding at the lower end in the length direction of the main frame body 4.

実施の形態６．
実施の形態１では、補強部材１５が縦部材、支持金具及び主枠下部材に固定されているが、補強部材１５を縦部材のみに固定してもよい。 Embodiment 6 FIG.
In Embodiment 1, the reinforcing member 15 is fixed to the vertical member, the support bracket, and the main frame lower member, but the reinforcing member 15 may be fixed only to the vertical member.

即ち、図１１は、この発明の実施の形態６によるエスカレータの主枠の長さ方向上端部を示す上面図である。なお、図１１は、図６に対応する図である。一対の上部縦部材１２のそれぞれは、第１の板部と、第１の板部に垂直な第２の板部とにより構成された断面Ｌ字状のアングル部材とされている。各上部縦部材１２は、主枠本体４の長さ方向に対して第１の板部を垂直にしてそれぞれ配置されている。上部支持金具６は、各上部縦部材１２の第１の板部に固定されている。   That is, FIG. 11 is a top view showing the upper end in the length direction of the main frame of the escalator according to the sixth embodiment of the present invention. FIG. 11 corresponds to FIG. Each of the pair of upper vertical members 12 is an angle member having an L-shaped cross section constituted by a first plate portion and a second plate portion perpendicular to the first plate portion. Each upper vertical member 12 is arranged with the first plate portion perpendicular to the length direction of the main frame body 4. The upper support fitting 6 is fixed to the first plate portion of each upper vertical member 12.

補強部材１５は、上部縦部材１２、上部支持金具６及び主枠下部材１４のうち、上部縦部材１２にのみ固定されている。この例では、補強部材１５は、上部縦部材１２に沿った長さを持つ円筒部材とされている。補強部材１５の長さは、上部縦部材１２の長さとほぼ同じになっている。従って、補強部材１５は、上部縦部材１２の全長にわたって上部縦部材１２に固定されている。なお、補強部材１５は、上部縦部材１２に沿った長さを持つ部材であればよく、例えば平板、チャネル部材、Ｈ形部材、Ｌ形部材又は中空部材等であってもよい。   The reinforcing member 15 is fixed only to the upper vertical member 12 among the upper vertical member 12, the upper support bracket 6 and the main frame lower member 14. In this example, the reinforcing member 15 is a cylindrical member having a length along the upper vertical member 12. The length of the reinforcing member 15 is substantially the same as the length of the upper vertical member 12. Therefore, the reinforcing member 15 is fixed to the upper vertical member 12 over the entire length of the upper vertical member 12. The reinforcing member 15 may be a member having a length along the upper vertical member 12, and may be, for example, a flat plate, a channel member, an H-shaped member, an L-shaped member, or a hollow member.

補強部材１５は、上部縦部材１２の内側（即ち、上部支持金具６からみて、上部縦部材１２の裏側）に配置され、第１及び第２の板部のそれぞれの面に接触した状態で上部縦部材１２にのみ溶接により固定されている。   The reinforcing member 15 is disposed on the inner side of the upper vertical member 12 (that is, on the back side of the upper vertical member 12 when viewed from the upper support fitting 6) and is in contact with the respective surfaces of the first and second plate portions. Only the vertical member 12 is fixed by welding.

主枠本体４の長さ方向下端部に設けられる補強部材の構成についても、主枠本体４の長さ方向上端部に設けられる補強部材１５の構成と同様である。他の構成は実施の形態１と同様である。   The configuration of the reinforcing member provided at the lower end portion in the length direction of the main frame main body 4 is the same as the configuration of the reinforcing member 15 provided at the upper end portion in the length direction of the main frame main body 4. Other configurations are the same as those in the first embodiment.

このように、各上部縦部材１２にのみ補強部材１５を固定することによっても、上部縦部材１２を補強することができ、主枠３の強度の向上を図ることができる。
また、主枠本体４の長さ方向下端部においても、同様の効果を得ることができる。 Thus, the upper vertical member 12 can be reinforced by fixing the reinforcing member 15 only to each upper vertical member 12, and the strength of the main frame 3 can be improved.
The same effect can also be obtained at the lower end of the main frame body 4 in the length direction.

なお、上記の例では、補強部材１５が各上部縦部材１２に溶接によって固定されているが、各上部縦部材１２に補強部材１５を締結具２０で固定してもよい。主枠本体４の長さ方向下端部においても同様に、各下部縦部材１１に補強部材を締結具２０で固定してもよい。   In the above example, the reinforcing member 15 is fixed to each upper vertical member 12 by welding, but the reinforcing member 15 may be fixed to each upper vertical member 12 with a fastener 20. Similarly, a reinforcing member may be fixed to each lower vertical member 11 with a fastener 20 at the lower end in the length direction of the main frame body 4.

また、実施の形態６の補強部材１５を実施の形態１〜５の補強部材１５と組み合わせて主枠本体４に設けてもよい。   Further, the reinforcing member 15 of the sixth embodiment may be provided on the main frame body 4 in combination with the reinforcing member 15 of the first to fifth embodiments.

実施の形態７．
実施の形態１では、補強部材１５が主枠本体４の内側から縦部材、支持金具及び主枠下部材に固定されているが、主枠本体４の外側に位置する構造物側から補強部材１５を縦部材、支持金具及び主枠下部材に固定するようにしてもよい。 Embodiment 7 FIG.
In the first embodiment, the reinforcing member 15 is fixed to the vertical member, the support bracket, and the main frame lower member from the inside of the main frame main body 4, but the reinforcing member 15 from the structure side located outside the main frame main body 4. May be fixed to the vertical member, the support metal fitting, and the main frame lower member.

即ち、図１２は、この発明の実施の形態７によるエスカレータの主枠の長さ方向上端部を示す側面図である。なお、図１２は、実施の形態１の図２に対応する図である。各補強部材１５は、上部構造物２側から上部縦部材１２、上部支持金具６及び主枠下部材１４に固定されている。各補強部材１５の上部は、上部支持金具６に接触した状態で締結具２０により上部支持金具６に固定されている。各補強部材１５の側部は、厚さの調整された図示しないスペーサを介して締結具２０により上部縦部材１２に固定されている。各補強部材１５の下部は、厚さの調整された図示しないスペーサを介して締結具２０により主枠下部材１４に固定されている。   That is, FIG. 12 is a side view showing the upper end in the length direction of the main frame of the escalator according to Embodiment 7 of the present invention. FIG. 12 is a diagram corresponding to FIG. 2 of the first embodiment. Each reinforcing member 15 is fixed to the upper vertical member 12, the upper support fitting 6, and the main frame lower member 14 from the upper structure 2 side. The upper part of each reinforcing member 15 is fixed to the upper support fitting 6 by the fastener 20 in a state where it is in contact with the upper support fitting 6. The side part of each reinforcement member 15 is being fixed to the upper vertical member 12 with the fastener 20 through the spacer which the thickness was adjusted which is not illustrated. The lower part of each reinforcing member 15 is fixed to the main frame lower member 14 by a fastener 20 through a spacer (not shown) whose thickness is adjusted.

主枠本体４の長さ方向下端部に設けられる補強部材の構成についても、主枠本体４の長さ方向上端部に設けられる補強部材１５の構成と同様である。他の構成は実施の形態１と同様である。   The configuration of the reinforcing member provided at the lower end portion in the length direction of the main frame main body 4 is the same as the configuration of the reinforcing member 15 provided at the upper end portion in the length direction of the main frame main body 4. Other configurations are the same as those in the first embodiment.

このようにしても、主枠３の強度の向上を図ることができ、実施の形態１と同様の効果を得ることができる。   Even if it does in this way, the improvement of the intensity | strength of the main frame 3 can be aimed at, and the effect similar to Embodiment 1 can be acquired.

なお、上記の例では、補強部材１５を構造物側から主枠本体４に固定する構成が実施の形態１に適用されているが、補強部材１５を構造物側から主枠本体４に固定する構成を実施の形態２〜５のそれぞれに適用してもよい。   In the above example, the configuration in which the reinforcing member 15 is fixed to the main frame body 4 from the structure side is applied to the first embodiment, but the reinforcing member 15 is fixed to the main frame body 4 from the structure side. The configuration may be applied to each of Embodiments 2 to 5.

実施の形態８．
また、各上記実施の形態では、補強部材１５に複数の貫通穴を設けてもよい。この場合、貫通穴の数や大きさは、補強部材１５の強度が確保される範囲内で設定される。このように補強部材１５に複数の貫通穴を設ければ、補強部材１５の軽量化や材料コストの削減を図ることができる。 Embodiment 8 FIG.
In each of the above embodiments, the reinforcing member 15 may be provided with a plurality of through holes. In this case, the number and size of the through holes are set within a range in which the strength of the reinforcing member 15 is ensured. If the reinforcing member 15 is provided with a plurality of through holes in this way, the weight of the reinforcing member 15 and the material cost can be reduced.

実施の形態９．
また、各上記実施の形態では、一対の補強部材１５が主枠本体４の幅方向について左右対称に配置されているが、左右のバランスが崩れて片側に応力集中が生じない程度であれば、左右非対称に各補強部材１５を配置してもよいし、左右の補強部材１５で形状を非対称としてもよい。即ち、左右のバランスが崩れて片側に応力集中が生じない程度であれば、各上記実施の形態のうち、互いに異なる実施の形態の補強部材１５を主枠本体４の左右で別個に適用してもよい。 Embodiment 9 FIG.
Further, in each of the above-described embodiments, the pair of reinforcing members 15 are arranged symmetrically in the width direction of the main frame main body 4, but if left and right balance is lost and stress concentration does not occur on one side, The reinforcing members 15 may be arranged asymmetrically in the left-right direction, or the shape may be asymmetrical with the left and right reinforcing members 15. That is, as long as the balance between the left and right sides is not broken and stress concentration does not occur on one side, the reinforcing members 15 of the different embodiments among the above embodiments are separately applied on the left and right sides of the main frame body 4. Also good.

実施の形態１０．
図１３は、この発明の実施の形態１０によるエスカレータの主枠の長さ方向上端部を示す正面図である。なお、図１３は、実施の形態１の図３に対応する図である。図において、上部支持金具６は、左右の上部縦部材１２に個別に固定された一対の支持固定部２１と、各支持固定部２１間を結合する結合部材２２とを有している。 Embodiment 10 FIG.
FIG. 13 is a front view showing the upper end in the length direction of the main frame of the escalator according to Embodiment 10 of the present invention. FIG. 13 is a diagram corresponding to FIG. 3 of the first embodiment. In the figure, the upper support fitting 6 has a pair of support fixing portions 21 individually fixed to the left and right upper vertical members 12, and a coupling member 22 that connects the support fixing portions 21.

各支持固定部２１は、主枠本体４の幅方向について互いに離して配置されている。また、各支持固定部２１は、上部縦部材１２に当てられた縦板部６ａと、縦板部６ａから上部構造物２側へ突出する横板部６ｂとをそれぞれ有している。従って、各支持固定部２１の断面形状は、縦板部６ａ及び横板部６ｂによってＬ字形になっている。この例では、各支持固定部２１の端部が補強区間Ａと中間区間Ｂとの境界に位置している。   The support fixing portions 21 are arranged apart from each other in the width direction of the main frame body 4. Each support fixing portion 21 has a vertical plate portion 6a applied to the upper vertical member 12, and a horizontal plate portion 6b protruding from the vertical plate portion 6a to the upper structure 2 side. Therefore, the cross-sectional shape of each support fixing portion 21 is L-shaped by the vertical plate portion 6a and the horizontal plate portion 6b. In this example, the end of each support fixing portion 21 is located at the boundary between the reinforcing section A and the intermediate section B.

結合部材２２は、所定の長さを持つ平板状の部材である。結合部材２２の幅寸法は、縦板部６ａの幅寸法よりも小さくなっている。即ち、結合部材２２は、支持固定部２１よりも細い部材とされている。結合部材２２の両端部は、縦板部６ａの裏面に重ねられている。結合部材２２は、縦板部６ａの下部に溶接により固定されている。   The coupling member 22 is a flat plate member having a predetermined length. The width dimension of the coupling member 22 is smaller than the width dimension of the vertical plate portion 6a. That is, the coupling member 22 is a member thinner than the support fixing portion 21. Both end portions of the coupling member 22 are overlapped on the back surface of the vertical plate portion 6a. The coupling member 22 is fixed to the lower portion of the vertical plate portion 6a by welding.

ここで、上部支持金具６の中間区間Ｂに位置する部分には、大きな応力が生じないことが構造解析により明らかになっている。従って、結合部材２２が支持固定部２１よりも細い部材であっても、上部支持金具６の強度は確保される。   Here, it is clear from structural analysis that no large stress is generated in the portion located in the intermediate section B of the upper support fitting 6. Therefore, even if the coupling member 22 is a member thinner than the support fixing portion 21, the strength of the upper support fitting 6 is ensured.

主枠本体４の長さ方向下端部の構成についても、主枠本体４の長さ方向上端部の構成と同様である。また、他の構成は実施の形態１と同様である。   The configuration of the lower end portion in the length direction of the main frame main body 4 is the same as the configuration of the upper end portion in the length direction of the main frame main body 4. Other configurations are the same as those in the first embodiment.

このようなエスカレータの主枠３では、上部支持金具６が、一対の上部縦部材１２に個別に固定され互いに離して配置された一対の支持固定部２１と、各支持固定部２１間を結合する結合部材２２とを有し、結合部材２２の幅寸法が各支持固定部２１の幅寸法よりも小さくなっているので、上部支持金具６の材料を少なくすることができる。上部支持金具６は通常、強度を確保するために高価となることから、上部支持金具６の材料を少なくすることにより上部支持金具６のコストを低減することができる。
主枠本体４の長さ方向下端部においても、同様の効果を得ることができる。 In the main frame 3 of such an escalator, the upper support fitting 6 is coupled to the pair of support fixing portions 21 and the pair of support fixing portions 21 that are individually fixed to the pair of upper vertical members 12 and arranged apart from each other. Since the width dimension of the coupling member 22 is smaller than the width dimension of each support fixing portion 21, the material of the upper support fitting 6 can be reduced. Since the upper support fitting 6 is usually expensive to ensure strength, the cost of the upper support fitting 6 can be reduced by reducing the material of the upper support fitting 6.
The same effect can be obtained at the lower end of the main frame body 4 in the length direction.

なお、上記の例では、各支持固定部２１間に結合部材２２が固定されているが、上部支持金具６の強度を確保することができるのであれば、結合部材２２はなくてもよい。このようにすれば、結合部材２２の製造費を削減することができ、上部支持金具６のコストの低減をさらに図ることができる。また、各支持固定部２１間に空間が生じるので、この空間に機器を配置する等、設計の自由度も向上させることができる。   In the above example, the coupling member 22 is fixed between the support fixing portions 21, but the coupling member 22 may be omitted as long as the strength of the upper support fitting 6 can be ensured. In this way, the manufacturing cost of the coupling member 22 can be reduced, and the cost of the upper support fitting 6 can be further reduced. In addition, since a space is generated between the support fixing portions 21, the degree of freedom of design can be improved, for example, by arranging devices in this space.

また、上記の例では、結合部材２２が各支持固定部２１に溶接により固定されているが、ボルト及びナットを有する締結具により結合部材２２を各支持固定部２１に固定してもよい。   In the above example, the coupling member 22 is fixed to each support fixing portion 21 by welding. However, the coupling member 22 may be fixed to each support fixing portion 21 with a fastener having a bolt and a nut.

また、上記の例では、結合部材２２が平板状の部材とされているが、結合部材２２を例えばチャネル部材、Ｈ形部材、Ｌ形部材又は中空部材等としてもよい。   In the above example, the coupling member 22 is a flat plate member. However, the coupling member 22 may be a channel member, an H-shaped member, an L-shaped member, a hollow member, or the like.

また、上記の例では、一対の支持固定部２１及び結合部材２２を有する上部支持金具６及び下部支持金具５の構成が実施の形態１の構成に適用されているが、一対の支持固定部２１及び結合部材２２を有する上部支持金具６及び下部支持金具５の構成を実施の形態２の構成に適用してもよい。   In the above example, the configuration of the upper support fitting 6 and the lower support fixture 5 having the pair of support fixing portions 21 and the coupling member 22 is applied to the configuration of the first embodiment. The configurations of the upper support fitting 6 and the lower support fitting 5 having the coupling member 22 may be applied to the configuration of the second embodiment.

また、各上記実施の形態では、補強部材１５が板状の部材となっているが、これに限定されず、補強部材１５を例えば棒状の部材等としてもよい。   Moreover, in each said embodiment, although the reinforcement member 15 is a plate-shaped member, it is not limited to this, For example, the reinforcement member 15 is good also as a rod-shaped member.

また、実施の形態４を除く各上記実施の形態では、上部縦部材１２に補強部材１５が固定されることにより上部縦部材１２を補強するようになっているが、補強部材１５を上部縦部材１２に固定せずに、上部縦部材１２自体を断面係数の高い部材（例えば、チャネル部材、Ｈ形部材又は中空部材等）とすることにより上部縦部材１２を補強するようにしてもよい。下部縦部材１１の補強についても同様である。   Moreover, in each said embodiment except Embodiment 4, although the upper vertical member 12 is reinforced by fixing the reinforcement member 15 to the upper vertical member 12, the reinforcement member 15 is used as an upper vertical member. The upper vertical member 12 may be reinforced by making the upper vertical member 12 itself a member having a high section modulus (for example, a channel member, an H-shaped member, or a hollow member). The same applies to the reinforcement of the lower vertical member 11.

また、各上記実施の形態では、この発明がエスカレータに適用されているが、動く歩道（乗客コンベヤ）にこの発明を適用してもよい。   Moreover, in each said embodiment, although this invention is applied to the escalator, you may apply this invention to the moving sidewalk (passenger conveyor).
