Description

本発明は、床面上で横動可能に設置される移動ラックの案内用レールとして利用できる埋設レール装置に関するものである。   The present invention relates to an embedded rail device that can be used as a guide rail for a movable rack that is installed to be laterally movable on a floor surface.

移動ラックの案内用レールとして利用される埋設レール装置は、既設コンクリート層の上に門形の支持部材を介してレールを所定高さで水平に支持し、このレールの表面と面一になるように前記既設コンクリート層の上に床面形成コンクリート層を打設して成る特許文献１に記載の埋設レール装置や、床面形成コンクリート層に形成した溝内に、床面とレール表面とが面一になるようにレールを支持し、前記溝内に合成樹脂を充填硬化させて成る特許文献２に記載の埋設レール装置などが知られているが、何れの場合もレールは、下側面が平坦な水平面であって、レール巾方向の縦断面形状が矩形のものが一般的であった。
特開平４−２５８４０１号公報 特開平１１−０１８８５０号公報 An embedded rail device used as a guide rail for a moving rack supports a rail horizontally at a predetermined height on a concrete layer via a gate-shaped support member, and is flush with the surface of the rail. The floor surface and the rail surface are placed in a buried rail device described in Patent Document 1 formed by placing a floor surface forming concrete layer on the existing concrete layer, or in a groove formed in the floor surface forming concrete layer. A buried rail device described in Patent Document 2 is known in which a rail is supported so as to become one, and a synthetic resin is filled and cured in the groove. In each case, the rail has a flat bottom surface. In general, the horizontal plane has a rectangular longitudinal section in the rail width direction.
JP-A-4-258401 Japanese Patent Laid-Open No. 11-018850

上記のような従来の矩形断面のレールを埋設して成る埋設レール装置では、レールの下側面が平坦な水平面であるため、支持する移動ラックの車輪から受ける荷重によってレール下側面に発生する単位面積当りの面圧が大きくなる。このレール下側面に発生する単位面積当りの面圧を小さくするためには、レールの巾を車輪巾よりも広くすると共にレール巾方向の曲げ剛性を高めるようにレールの厚さも大きくしなければならず、レール自体の大幅なコストアップは勿論のこと、レールの敷設コストも高くなる。又、レールの下側面が平坦な水平面であるため、このレールを埋めるように既設コンクリート層の上に打設されるコンクリート内の気泡や溝内に充填される合成樹脂内の気泡がレールの下側に滞留し易く、レール下側面に発生する単位面積当りの面圧が大きいことと相まって、レールの不規則な沈下を招き、移動ラックなどの走行に支障を来す恐れがあった。   In the buried rail device formed by embedding the conventional rectangular cross-section rail as described above, since the lower side surface of the rail is a flat horizontal surface, the unit area generated on the lower side surface of the rail due to the load received from the wheels of the moving rack to be supported The contact pressure per contact increases. In order to reduce the surface pressure per unit area generated on the rail lower surface, the rail width must be wider than the wheel width and the rail thickness must be increased to increase the bending rigidity in the rail width direction. Of course, the cost of laying the rails increases as well as the cost of the rails. In addition, since the lower surface of the rail is a flat horizontal surface, bubbles in the concrete placed on the existing concrete layer and bubbles in the synthetic resin filled in the groove are buried under the rail to fill the rail. In combination with a large surface pressure per unit area generated on the lower side surface of the rail, the rail may be irregularly settled, which may hinder the traveling of a moving rack or the like.

本発明は上記のような従来の問題点を解消し得る埋設レール装置を提供することを目的とするものであって、請求項１に記載の埋設レール装置は、後述する実施形態の参照符号を付して示すと、レール表面８が床面３と面一になるようにレール４Ａ，４Ｃを埋設した埋設レール装置であって、レール巾方向の縦断面形状における下側面７を下に凸の円弧形に形成した構成となっている。   An object of the present invention is to provide an embedded rail device that can solve the conventional problems as described above, and the embedded rail device according to claim 1 uses the reference numerals of the embodiments described later. If it attaches and shows, it is an embedding rail device which embedded rails 4A and 4C so that rail surface 8 may become flush with floor surface 3, Comprising: The lower side 7 in the longitudinal section shape of a rail width direction is projected downward It has a configuration formed in an arc shape.

上記請求項１に記載の本発明を実施するについて、具体的には請求項２に記載のように、レール長さ方向の適当間隔おきの位置の前記円弧形下側面７を、門形のレール支持部材１１の中央部に形成した下に凸の円弧形部分１１ｃに嵌合させて互いに溶接し、このレール支持部材１１の左右両端部（取付け板部１１ｂ）を既設コンクリート層１４に固定し、この既設コンクリート層１４の上に、前記レール表面８と面一に床面形成コンクリート層１５を打設することができる。   In carrying out the present invention described in claim 1, specifically, as described in claim 2, the arc-shaped lower side surface 7 at appropriate intervals in the rail length direction is formed in a portal shape. The rail support member 11 is fitted into a downwardly convex arcuate portion 11c formed at the center portion and welded to each other, and the left and right ends (mounting plate portion 11b) of the rail support member 11 are fixed to the existing concrete layer 14. Then, the floor forming concrete layer 15 can be placed on the existing concrete layer 14 so as to be flush with the rail surface 8.

又、請求項３に記載の埋設レール装置は、レール表面８が床面３と面一になるようにレール４Ｂを埋設した埋設レール装置であって、レール巾方向の縦断面形状における下側面１８を下に凸の倒立山形に形成した構成となっている。   The embedded rail device according to claim 3 is an embedded rail device in which the rail 4B is embedded so that the rail surface 8 is flush with the floor surface 3, and the lower side surface 18 in the longitudinal sectional shape in the rail width direction. Is formed in an inverted inverted mountain shape.

上記請求項３に記載の構成の本発明を実施するについて、具体的には請求項４に記載のように、レール長さ方向の適当間隔おきの位置の前記倒立山形下側面１８を、門形のレール支持部材１１の中央部に形成した下に凸の倒立山形部分１１ｄに嵌合させて互いに溶接し、このレール支持部材１１の左右両端部（取付け板部１１ｂ）を既設コンクリート層１４に固定し、この既設コンクリート層１４の上に、前記レール表面８と面一に床面形成コンクリート層１５を打設することができる。   In practicing the present invention having the structure described in claim 3, specifically, as described in claim 4, the inverted mountain-shaped lower side surface 18 at positions at appropriate intervals in the rail length direction is formed as a gate shape. The rail support member 11 is fitted to a downwardly projecting inverted chevron 11d formed at the center of the rail support member 11 and welded to each other, and the left and right ends (mounting plate portion 11b) of the rail support member 11 are fixed to the existing concrete layer 14. Then, the floor forming concrete layer 15 can be placed on the existing concrete layer 14 so as to be flush with the rail surface 8.

上記請求項１又は３に記載の本発明に係る埋設レール装置によれば、レール巾方向の縦断面形状における下側面が下に凸の円弧形又は倒立山形であるため、レール巾が同一であるとすると、当該レールを支持するコンクリート層又は充填樹脂層に対する設置面積が広くなり、単位面積当りの面圧が小さくなる。しかも、このレールを埋めるように既設コンクリート層の上に打設されるコンクリート内の気泡や溝内に充填される合成樹脂内の気泡がレールの前記円弧形又は倒立山形の下側面に沿って左右両側上方に誘導され、レール下側面に接して滞留することが極めて少なくなるので、レール下側面の面圧が小さくなることと相まって、レールの不規則な沈下を招く恐れが殆ど解消する。勿論、レールの巾や厚さを特に大きくする必要もないので、コストアップにつながることもない。   According to the buried rail device according to the first or third aspect of the present invention, since the lower side surface in the longitudinal cross-sectional shape in the rail width direction is a downwardly convex arc shape or inverted mountain shape, the rail width is the same. If it exists, the installation area with respect to the concrete layer or filling resin layer which supports the said rail will become large, and the surface pressure per unit area will become small. Moreover, air bubbles in the concrete cast on the existing concrete layer to fill the rail or air bubbles in the synthetic resin filled in the groove are along the lower surface of the arc shape or the inverted mountain shape of the rail. Since it is guided to the upper side of the right and left sides and stays in contact with the lower side surface of the rail, the possibility of causing the irregular settlement of the rail is almost eliminated in combination with the reduction of the surface pressure on the lower side surface of the rail. Of course, it is not necessary to increase the width and thickness of the rail, so that the cost is not increased.

尚、請求項２や４に記載の構成によれば、レール下側面が下に凸の円弧形又は倒立山形であるレールでありながら、当該レールを、既設コンクリート層（一次コンクリート層）の上に打設される床面形成コンクリート層（二次コンクリート層）内にレール下側面を利用して容易に埋設することができる。特に請求項４に記載の構成によれば、レール支持部材の倒立山形部分にレールの倒立山形下側面を嵌合させるだけで当該レールの姿勢が決まり、レールを所定の姿勢でレール支持部材に溶接する作業が容易に行える。   In addition, according to the structure of Claim 2 or 4, although the rail lower surface is a rail which is a convex arcuate shape or an inverted mountain shape, the rail is placed on the existing concrete layer (primary concrete layer). The floor surface forming concrete layer (secondary concrete layer) to be laid can be easily embedded using the rail lower surface. In particular, according to the configuration of the fourth aspect, the posture of the rail is determined simply by fitting the lower side surface of the inverted mountain shape of the rail to the inverted mountain shape portion of the rail support member, and the rail is welded to the rail support member in a predetermined posture. Can be done easily.

以下に本発明の具体的実施例を添付図に基づいて説明すると、図１Ａにおいて、１Ａ，１Ｂは固定ラック、２Ａ，２Ｂは両固定ラック１Ａ，１Ｂ間に設置される移動ラックである。各移動ラック２Ａ，２Ｂは、レール表面が床面３と同一レベルになるように両固定ラック１Ａ，１Ｂ間の床に埋設された複数本のレール４と、これら各レール４上を転動するように移動ラック２Ａ，２Ｂの底部に軸支された車輪５とによって、両固定ラック１Ａ，１Ｂ間で横動可能に支持されている。尚、従来周知の移動ラック装置であるから詳細図は省略しているが、レール４は、移動ラック２Ａ，２Ｂの移動方向に対し直交するラック間通路６の奥行き方向に適当間隔おきに複数本が並列配置され、各移動ラック２Ａ，２Ｂには、各レール４に対し複数個の車輪５が設けられ、各移動ラック２Ａ，２Ｂが備える車輪５の内、少なくとも１つの車輪がモーター駆動される。更に、少なくとも１つのレール４上を転動する複数個の車輪５には鍔付き車輪が採用され、この複数個の鍔付き車輪とこれに対応するレール４とが係合することにより、ラック間通路６の奥行き方向に関する移動ラック２Ａ，２Ｂの位置が規制される。   A specific embodiment of the present invention will be described below with reference to the accompanying drawings. In FIG. 1A, 1A and 1B are fixed racks, and 2A and 2B are mobile racks installed between the fixed racks 1A and 1B. Each of the movable racks 2A and 2B rolls on the rails 4 and a plurality of rails 4 embedded in the floor between the fixed racks 1A and 1B so that the rail surface is at the same level as the floor surface 3. Thus, the fixed racks 1A and 1B are supported so as to be laterally movable by the wheels 5 pivotally supported on the bottoms of the movable racks 2A and 2B. Although a detailed drawing is omitted because it is a conventionally known mobile rack device, a plurality of rails 4 are provided at appropriate intervals in the depth direction of the inter-rack passage 6 perpendicular to the moving direction of the moving racks 2A and 2B. Are arranged in parallel, each moving rack 2A, 2B is provided with a plurality of wheels 5 for each rail 4, and at least one of the wheels 5 provided in each moving rack 2A, 2B is motor-driven. . Further, the plurality of wheels 5 that roll on the at least one rail 4 are provided with hooked wheels, and the plurality of hooked wheels and the corresponding rails 4 are engaged with each other, so that The positions of the movable racks 2A and 2B in the depth direction of the passage 6 are restricted.

図１Ｂ及び図２は、車輪５の内の鍔付き車輪５Ａと、レール４の内の鍔付き車輪５Ａを支持案内する溝付きレール４Ａとを示している。溝付きレール４Ａは、レール巾方向の縦断面形状における下側面７が下に凸の円弧形であると共に平坦なレール表面８を有する、レール巾方向の縦断面形状が切円形のレールであって、平坦なレール表面８の巾方向の中央位置に鍔付き車輪５Ａの中央鍔部９が遊嵌する溝１０が形成されている。   FIG. 1B and FIG. 2 show a flanged wheel 5 </ b> A in the wheel 5 and a grooved rail 4 </ b> A that supports and guides the flanged wheel 5 </ b> A in the rail 4. The grooved rail 4A is a rail whose longitudinal cross-sectional shape in the rail width direction has a rounded arc shape with the lower side surface 7 in the longitudinal cross-sectional shape in the rail width direction having a downwardly convex arc shape and a flat rail surface 8. Thus, a groove 10 is formed in the central position of the flat rail surface 8 in the width direction so that the central flange 9 of the flanged wheel 5A is loosely fitted.

上記溝付きレール４Ａの敷設作業について説明すると、溝付きレール４Ａには、その円弧形下側面７のレール長さ方向の適当間隔おきの位置にレール支持部材１１が固着されている。このレール支持部材１１は、レール支持用板部１１ａの左右両側に一段低い取付け板部１１ｂを有するように、帯状鉄板を門形（正確にはハット形）に曲げ加工したものであって、レール支持用板部１１ａの中央部には下に凸の円弧形部分１１ｃが形成されており、この円弧形部分１１ｃに溝付きレール４Ａの円弧形下側面７の下半部を面接触状態で嵌合させた状態で両者を溶接により互いに固着している。   The laying operation of the grooved rail 4A will be described. The rail support members 11 are fixed to the grooved rail 4A at positions of the arc-shaped lower side surface 7 at appropriate intervals in the rail length direction. The rail support member 11 is formed by bending a belt-like iron plate into a gate shape (precisely a hat shape) so as to have a lower mounting plate portion 11b on both the left and right sides of the rail support plate portion 11a. A downwardly convex arc-shaped portion 11c is formed at the center of the support plate portion 11a, and the lower half of the arc-shaped lower side surface 7 of the grooved rail 4A is in surface contact with the arc-shaped portion 11c. Both are fixed to each other by welding in a state of being fitted in a state.

而して、溝付きレール４Ａのレール長さ方向の適当間隔おきの位置に固着されているレール支持部材１１の左右両側の取付け板部１１ｂを、アンカーボルト１２と締結用ナット１３を利用して既設コンクリート層（一次コンクリート層）１４の上方所定高さに固定して、レール表面８が水平になるように溝付きレール４Ａを支持させる。この状態で既設コンクリート層１４の上に床面形成コンクリート層（二次コンクリート層）１５を、当該床面形成コンクリート層１５で形成される床面３ａとレール表面８とが面一になるように打設する。   Thus, the mounting plate portions 11b on both the left and right sides of the rail support member 11 fixed at appropriate intervals in the rail length direction of the grooved rail 4A are used using the anchor bolt 12 and the fastening nut 13. The grooved rail 4A is supported so that the rail surface 8 is horizontal by fixing it to a predetermined height above the existing concrete layer (primary concrete layer) 14. In this state, the floor surface forming concrete layer (secondary concrete layer) 15 is placed on the existing concrete layer 14 so that the floor surface 3a formed by the floor surface forming concrete layer 15 and the rail surface 8 are flush with each other. To cast.

上記のようにして構成された埋設レール装置における溝付きレール４Ａは、図２Ｂで示すように床面形成コンクリート層１５で支持される下側面７が下に凸の円弧形であるため、図７に示す同一巾の矩形断面の従来の埋設レール装置における溝付きレール１６の平坦水平下側面１７と比較して、床面形成コンクリート層１５で支持される下側面７が広くなっており、鍔付き車輪５Ａから受ける移動ラック２Ａ，２Ｂの荷重が分散し、床面形成コンクリート層１５と下側面７との間の単位面積当りの面圧が小さくなる。又、図７に示す矩形断面の従来の埋設レール装置における溝付きレール１６では、平坦水平下側面１７の下に床面形成コンクリート層１５を形成する打設コンクリート中の気泡１５ａが滞留し易いが、図２Ｂで示す円弧形下側面７を有する本発明の溝付きレール４Ａでは、打設コンクリート中の気泡は円弧形下側面７に沿って左右両側上方に誘導され易いので、円弧形下側面７の下に打設コンクリート中の気泡が滞留することは殆どなくなる。   As shown in FIG. 2B, the grooved rail 4A in the buried rail device configured as described above has an arc shape in which the lower side surface 7 supported by the floor surface forming concrete layer 15 is convex downward. Compared with the flat horizontal lower side surface 17 of the grooved rail 16 in the conventional buried rail device of the same width rectangular cross section shown in FIG. 7, the lower side surface 7 supported by the floor surface forming concrete layer 15 is widened. The load of the movable racks 2A and 2B received from the attached wheels 5A is dispersed, and the surface pressure per unit area between the floor surface forming concrete layer 15 and the lower side surface 7 is reduced. Further, in the grooved rail 16 in the conventional buried rail device having the rectangular cross section shown in FIG. 7, the bubbles 15 a in the cast concrete forming the floor surface forming concrete layer 15 are likely to stay below the flat horizontal lower side surface 17. In the grooved rail 4A according to the present invention having the arc-shaped lower side surface 7 shown in FIG. 2B, the bubbles in the cast concrete are easily guided upward along the arc-shaped lower side surface 7 on both the left and right sides. Air bubbles in the cast concrete hardly remain below the lower side surface 7.

尚、本発明の埋設レール装置におけるレールは、上記実施形態に示した円弧形下側面７を有するものに限定されない。例えば、図３に示すように、円弧形下側面７に代えて倒立山形下側面１８を形成することもできる。この場合、図４に示すように、倒立山形下側面１８の両側に高さの低い垂直壁面１９が形成されても良い。これら倒立山形下側面１８を有する溝付きレール４Ｂの場合、レール支持部材１１のレール支持用板部１１ａには、倒立山形下側面１８の下半部が嵌合する倒立山形部分１１ｄを形成すれば良い。而して、レール支持部材１１の倒立山形部分１１ｄに溝付きレール４Ｂの倒立山形下側面１８の下半部を嵌合させるだけで、当該溝付きレール４Ｂのレール表面８が、レール支持部材１１の左右両レール支持用板部１１ａを結ぶ仮想平面と平行になるように構成できるので、溝付きレール４Ｂに対するレール支持部材１１の溶接による取付け作業が容易になる。   The rail in the embedded rail device of the present invention is not limited to the rail having the arc-shaped lower side surface 7 shown in the above embodiment. For example, as shown in FIG. 3, an inverted mountain-shaped lower side surface 18 can be formed instead of the arc-shaped lower side surface 7. In this case, as shown in FIG. 4, low vertical wall surfaces 19 may be formed on both sides of the inverted mountain-shaped lower side surface 18. In the case of the grooved rail 4 </ b> B having the inverted mountain-shaped lower side surface 18, the rail supporting plate 11 a of the rail support member 11 is formed with an inverted mountain-shaped portion 11 d that fits the lower half of the inverted mountain-shaped lower side surface 18. good. Thus, the rail surface 8 of the grooved rail 4B can be brought into contact with the rail support member 11 simply by fitting the lower half of the inverted mountain shape lower side surface 18 of the grooved rail 4B to the inverted mountain shape portion 11d of the rail support member 11. Since it can be configured to be parallel to a virtual plane connecting the left and right rail supporting plate portions 11a, it is easy to attach the rail supporting member 11 to the grooved rail 4B by welding.

以上の実施形態では、鍔付き車輪５Ａを支持案内する溝付きレール４Ａ，４Ｂを例示したが、図５に示すように、鍔無し車輪を支持案内する溝無しレール４Ｃに関しても本発明を適用して実施することができる。勿論、図５では溝無しレール４Ｃとして円弧形下側面７を備えたレールを例示しているが、図４や図５に示したような倒立山形下側面１８を備えた溝無しレールとしても実施できる。   In the above embodiment, the grooved rails 4A and 4B for supporting and guiding the flanged wheel 5A are exemplified. However, as shown in FIG. 5, the present invention is applied also to the grooveless rail 4C for supporting and guiding the flangeless wheel. Can be implemented. Of course, in FIG. 5, a rail having the arc-shaped lower side surface 7 is illustrated as the grooveless rail 4C, but a grooveless rail having the inverted mountain-shaped lower side surface 18 as shown in FIG. Can be implemented.

更に、図６に示すように、既設コンクリート層１４で床面３を形成させる場合、当該既設コンクリート層１４の床面３に凹溝部２０を刻設し、上記各実施形態で示した本発明に係るレール、例えば円弧形下側面７を備えた溝無しレール４Ｃを、そのレール表面８に取付けネジ２１により着脱自在に取り付けたアングル材などのレール吊下げ部材２２の両端部を凹溝部２０の両側で既設コンクリート層１４の床面３にコンクリート釘２３などで仮止めすることにより、レール表面８が床面３と面一になるように凹溝部２０内に吊下げ、係る状態で凹溝部２０内に合成樹脂２４を充填硬化させ、その後、レール吊下げ部材２２を取り外す方法により溝無しレール４Ｃを凹溝部２０内に埋設固定することもできる。この場合、合成樹脂２４に代えてモルタルを充填硬化させることもできる。即ち、円弧形下側面７又は倒立山形下側面１８を備えた本発明の溝付きレール４Ａ，４Ｂや溝無しレール４Ｃの埋設方法は限定されるものではない。   Further, as shown in FIG. 6, when the floor surface 3 is formed with the existing concrete layer 14, a groove 20 is formed on the floor surface 3 of the existing concrete layer 14, and the present invention described in the above embodiments is applied. Such a rail, for example, a grooveless rail 4C having an arcuate lower side surface 7 is attached to the rail surface 8 with a mounting screw 21 so as to be detachable. By temporarily fixing the floor surface 3 of the existing concrete layer 14 on both sides with concrete nails 23 or the like, the rail surface 8 is suspended in the recessed groove portion 20 so as to be flush with the floor surface 3, and in this state, the recessed groove portion 20 is suspended. The grooveless rail 4C can also be embedded and fixed in the recessed groove portion 20 by filling and curing the synthetic resin 24 therein and then removing the rail suspension member 22. In this case, mortar can be filled and cured instead of the synthetic resin 24. That is, the embedding method of the grooved rails 4A and 4B and the grooveless rail 4C of the present invention having the arc-shaped lower side surface 7 or the inverted mountain-shaped lower side surface 18 is not limited.
