Description

この発明は工事現場の搬送装置に関する。更に詳しくは、高架道路や橋梁の工事現場で鉄筋等の建設資材を搬送するために簡便に設置して使用することができる搬送装置に関する。   The present invention relates to a transfer device at a construction site. More particularly, the present invention relates to a transport device that can be easily installed and used for transporting construction materials such as reinforcing bars on construction sites of elevated roads and bridges.

高架道路や橋梁の工事現場に鉄筋などの建設資材を搬入する方法としては、トラックで建設資材を工事現場の近くに搬送し、クレーンにより荷揚げして工事現場に搬入する方法がとられている。
ここで、高架道路工事や橋梁工事では工事現場が長い距離範囲にわたるが、峡谷の上や街中ではトラックにより建設資材を搬入できる搬入口が限られること、クレーンを設置できる場所が限られることから、建設資材を工事現場内の建設資材を使用する施工場所へ直接クレーンで荷揚げすることが困難である。そこで、建設資材を工事現場内の積載場所へ一端荷揚げした後、積載場所から施工場所まで搬送することが必要となる。
ここで、高架道路や橋梁の基礎となる鋼材桁が敷設された状態では鋼材桁の上面にはコンクリートに埋設される多数のスタッドが埋め込まれているため、鋼材桁上で建設資材の搬送路を確保することは困難である。また、床板設置後においても、工事現場の床部の一部にはコンクリートに埋設される鉄筋が既に配設されている等により床部が平坦でないため、床板上においても建築資材の搬送路を確保することが困難である。
そのため、鉄筋等の建設資材を積載場所から施工場所まで搬送する作業は、もっぱら作業者の人力に頼っている。そこで、作業者は足場の悪い中を重量のある鉄筋等の建設資材を担いで運ぶことが必要となるため、作業者への負担が大きなものとなっている。 As a method of carrying construction materials such as reinforcing bars to the construction site of an elevated road or a bridge, a method of transporting the construction material near the construction site with a truck, unloading it with a crane, and carrying it to the construction site is used.
Here, in the construction of elevated roads and bridges, the construction site spans a long distance range, but on the canyon and in the city, there are limited entrances where construction materials can be carried by truck, and the places where cranes can be installed are limited. It is difficult to unload the construction material directly to the construction site using the construction material in the construction site with a crane. Therefore, after the construction material is once unloaded to the loading place in the construction site, it is necessary to transport the construction material from the loading place to the construction place.
Here, in the state where steel girders that are the basis of elevated roads and bridges are laid, a large number of studs buried in concrete are embedded on the upper surface of the steel girders. It is difficult to secure. In addition, even after the floorboards are installed, the floors are not flat due to the fact that some of the floors at the construction site are already provided with reinforcing bars embedded in concrete. It is difficult to secure.
For this reason, the work of transporting construction materials such as reinforcing bars from the loading place to the construction place relies solely on the human power of the worker. Therefore, since it is necessary for the worker to carry heavy construction materials such as reinforcing bars through a poor scaffold, the burden on the worker is large.

ここで、作業者の負担を軽減するものとして、特開２００５−１８８０７９号公報（特許文献１）には、橋梁工事の工事現場で鉄筋等の建設資材を搬送する荷役方法及び荷役装置の従来技術が開示されている。特許文献１に記載の従来技術は、工事現場の鋼桁のフランジに立設された検棒を利用して単軌条を支持し、単軌条を搬送路とし、単軌条上を走行する駆動台車により荷積み台車を牽引し、荷積み台車に建設資材を積載して搬送するというものである。
この方法によれば、鉄筋等の建設資材を作業者が担いで運搬しなくてもよい。
特開２００５−１８８０７９号公報 Here, as a method for reducing the burden on the worker, Japanese Patent Laid-Open No. 2005-188079 (Patent Document 1) discloses a conventional loading / unloading method and a loading / unloading apparatus for conveying construction materials such as reinforcing bars at a construction site for bridge construction. Is disclosed. The prior art described in Patent Document 1 is based on a driving carriage that supports a single rail using a test rod erected on a flange of a steel girder at a construction site, uses a single rail as a transport path, and runs on the single rail. The truck is towed and loaded with construction materials and transported.
According to this method, the worker does not have to carry construction materials such as reinforcing bars.
JP 2005-188079 A

しかしながら、特許文献１に記載の方法では、駆動台車を使用するので、駆動台車の走行制御のために、作業者が駆動台車の移動に合わせて一緒に移動しなければならない。また、運搬荷重が大きくなる場合は、台車を安定走行させるために搬送路の補強が必要となり、搬送路の構造が大がかりで複雑なものとなるため、搬送路の設置及び撤去に手間がかかることとなる。   However, in the method described in Patent Document 1, since a driving cart is used, an operator must move together with the movement of the driving cart to control the driving cart. In addition, when the transport load becomes large, it is necessary to reinforce the transport path in order to make the carriage run stably, and the structure of the transport path becomes large and complicated, so it takes time to install and remove the transport path. It becomes.

そこで、本発明が解決しようとする課題は、高架道路や橋梁の工事現場で鉄筋等の建設資材を手軽に搬送することができ、搬送路の設置及び撤去を簡便に行うことができる工事現場の搬送装置を提供することである。   Thus, the problem to be solved by the present invention is that the construction materials such as reinforcing bars can be easily transported on the construction site of the elevated road and the bridge, and the construction site where the transportation path can be easily installed and removed. It is to provide a transport device.

Detachment of the transfer platform from the transfer path is suppressed. Further, when the conveyance table comes into contact with the protruding piece, the frictional resistance with the protruding piece is reduced by the rotation of the roller, so that it is possible to suppress an increase in resistance when the conveying table moves in the conveyance path.

上記本発明の各発明によれば、次の効果が得られる。
まず、上述の第１の発明によれば、支柱を鋼材桁に取付けて支柱間に連結部材を連結すれば搬送路を設置でき、連結部材を取外して支柱を取外せば搬送路を撤去できるため、搬送路の設置や撤去が容易である。また、この搬送装置は、ローラの回転で搬送台が移動する構成であり搬送の負荷は非常に小さいため、搬送のための特別な動力は不要であり、建設資材を積んだ搬送台を人力により搬送路上で移動させることができる。そこで、搬送台にロープを取付けて作業者がロープを引き寄せることで、作業者が移動することなく、工事現場で手軽に建設資材を搬送することができる。
次に上述の第２の発明によれば、ローラを支持する支柱を嵌合させる計測棒は、予め鋼材桁に設置されているものを利用する。よって、支柱を立脚させるために鋼材桁に対して追加の施工作業は不要である。また、計測棒は等間隔に設置されているので、ローラを支持する支柱も等間隔となる。
次に上述の第３の発明によれば、搬送台が搬送路の片側に寄ると、搬送台の側面に設けられた自転可能なコロが連結部材から搬送路の内側に突出した突起片に当接するため、搬送台の搬送路からの離脱が抑止される。また、搬送台が突起片に当接したときは、コロの回転により突起片との摩擦抵抗が減少するため、搬送台が搬送路を移動するときの抵抗の増大を抑えることができる。 According to each invention of the present invention, the following effects can be obtained.
First, according to the above-mentioned first invention, the transportation path can be installed by attaching the support column to the steel beam and connecting the connection member between the support columns, and the transportation path can be removed by removing the connection member and removing the support column. The installation and removal of the transport path is easy. In addition, this transport device has a configuration in which the transport platform is moved by the rotation of the rollers, and the load of transport is very small, so no special power is required for transport, and the transport platform loaded with construction materials is manually It can be moved on the transport path. Therefore, by attaching the rope to the transport table and the operator pulling the rope, the construction material can be easily transported at the construction site without the worker moving.
Next, according to the above-mentioned second invention, the measuring rod for fitting the column supporting the roller is one that is previously installed on the steel beam.

以下、本発明を実施するための最良の形態について説明する。
図１に本発明の一実施例である搬送装置１０の外観斜視図を示す。搬送装置１０は、高架道路を建設する工事現場に基礎として予め設置された鋼材桁１２の上に搬送路１６を固定設置し、搬送路１６上で搬送物を載置する搬送台３０を移動させて鉄筋等の建設資材を搬送する搬送装置である。搬送路１６は鉄製の支柱２０と鉄製の連結部材４０から構成される。
図２に搬送路１６を構成する支柱２０の外観斜視図を示す。支柱２０は自転可能なローラ２２と、ローラ２２を支えるローラ支持部２６と、中空に形成された脚部２４を備えている。そして、ローラ支持部２６はローラ２２の下方で補強材２７により補強され、ローラ支持部２６の上端には連結部材４０を取付けるための支持孔２８が明けられている。
図３に連結部材４０の外観斜視図を示す。連結部材４０は断面形状がＬ字型で支柱２０の設置間隔と同じ長さを有し、両端に支柱２０と連結するための連結孔４４が明けられている。Ｌ字のうち連結孔４４が明けられている辺が支柱２０に連結され、他方の辺が搬送台３０の搬送路１６からの離脱を抑止する突起片４２となる。 Hereinafter, the best mode for carrying out the present invention will be described.
FIG. 1 shows an external perspective view of a transfer apparatus 10 according to an embodiment of the present invention. The conveyance device 10 fixes and installs a conveyance path 16 on a steel girder 12 installed in advance on the construction site where an elevated road is constructed, and moves a conveyance table 30 on which a conveyance object is placed on the conveyance path 16. This is a transport device that transports construction materials such as reinforcing bars. The conveyance path 16 includes an iron support 20 and an iron connecting member 40.
FIG. 2 shows an external perspective view of the support column 20 constituting the conveyance path 16. The column 20 includes a roller 22 that can rotate, a roller support portion 26 that supports the roller 22, and a leg portion 24 that is hollow. The roller support portion 26 is reinforced by a reinforcing material 27 below the roller 22, and a support hole 28 for attaching the connecting member 40 is formed at the upper end of the roller support portion 26.
FIG. 3 shows an external perspective view of the connecting member 40. The connecting member 40 has an L-shaped cross section and has the same length as the installation interval of the support columns 20, and connection holes 44 for connecting to the support columns 20 are opened at both ends. Of the L shape, the side where the connection hole 44 is opened is connected to the support column 20, and the other side is a protruding piece 42 that prevents the transfer platform 30 from being detached from the transfer path 16.

ここで搬送路１６の設置方法について説明する。まず、鋼材桁１２の上フランジ面に固着されたナット（図示せず）に螺着された計測棒１４に、支柱２０の脚部２４を嵌合させて支柱２０を鋼材桁１２に立脚させる。ここで、脚部２４と計測棒１４は隙間嵌めの状態となる。なお、ナット及び計測棒１４は、高架道路を建設するときに床部に打設されるコンクリートの厚さを計測するために予め鋼材桁１２に設置されているものを利用するものであるので、支柱２０を立脚させるために鋼材桁１２に対する追加の施工作業は不要である。また、計測棒１４は等間隔に設置されているので、支柱２０も等間隔に立脚することとなる。実施例では計測棒１４の間隔は１．５メートルであり、支柱２０の間隔も１．５メートルとなる。
次に、連結部材４０の両端の連結孔４４を隣接する支柱２０の支持孔２８にそれぞれ合わせてボルトを通してナットで締結する。連結部材４０は支柱２０のローラ支持部２６の両側に取付けて固定する。その後、支柱２０の脚部２４に設けられたネジ孔２５でネジ止めして、脚部２４を計測棒１４に固定する。これで、搬送路１６の設置は終了する。
なお、搬送路１６の撤去は上記の逆の手順を踏めばよい。このように、実施例では、特別な工具を用いることなく人手により簡単に搬送路１６の設置及び撤去をすることができる。 Here, the installation method of the conveyance path 16 is demonstrated. First, the support rod 20 is made to stand on the steel beam 12 by fitting the leg portion 24 of the column 20 to the measuring rod 14 screwed to the nut (not shown) fixed to the upper flange surface of the steel beam 12. Here, the leg portion 24 and the measuring rod 14 are in a state of gap fitting. In addition, since the nut and the measuring rod 14 use what was previously installed in the steel material girder 12 in order to measure the thickness of the concrete laid on the floor when constructing the elevated road, In order to make the support column 20 stand, an additional construction work on the steel beam 12 is unnecessary. Further, since the measuring rods 14 are installed at equal intervals, the support columns 20 are also erected at equal intervals. In the embodiment, the interval between the measuring bars 14 is 1.5 meters, and the interval between the support columns 20 is also 1.5 meters.
Next, the connecting holes 44 at both ends of the connecting member 40 are respectively aligned with the support holes 28 of the adjacent struts 20 and tightened with nuts through bolts. The connecting member 40 is attached and fixed to both sides of the roller support portion 26 of the support column 20. Thereafter, the leg 24 is fixed to the measuring rod 14 by screwing with a screw hole 25 provided in the leg 24 of the column 20. This completes the installation of the conveyance path 16.
In addition, the removal of the conveyance path 16 should just follow said reverse procedure. Thus, in the embodiment, the conveyance path 16 can be easily installed and removed manually without using a special tool.

図４に実施例における搬送台３０の外観斜視図を示す。搬送台３０は、支柱２０の間隔の２倍を越える長さとローラ２２よりもやや狭い幅の鉄枠の中に積載物を支える桁を渡した梯子のような外形を有している。そして、長さ方向の両端には搬送台３０を引っ張るためのロープを結ぶロープ孔３９が設けてある。また、長さ方向の両端の下面にはローラ２２への搬送台３０の乗り上げを滑らかに行うための鍔状でやや上向きに形成された滑片３８が設けられている。
搬送台３０の長さ方向の両端付近の両側面には、コの字型のコロ支持具３４に軸支された自転可能な縦方向のコロ３２が設けられている。また、搬送台３０の両則の上面には積載された搬送物が搬送台３０からこぼれ落ちることを防止するため、着脱が可能な丸棒３６が立設されている。なお、実施例では搬送台３０の長さは４メートルである。 FIG. 4 is an external perspective view of the transport table 30 in the embodiment. The carriage 30 has a ladder-like outer shape in which a girder that supports a load is placed in an iron frame having a length exceeding twice the interval between the columns 20 and a width slightly narrower than that of the roller 22. And the rope hole 39 which connects the rope for pulling the conveyance stand 30 is provided in the both ends of the length direction. Further, on the lower surfaces of both ends in the length direction, there are provided sliding pieces 38 that are formed in a bowl shape and slightly upward so as to smoothly carry the carriage 30 onto the rollers 22.
On both side surfaces in the vicinity of both ends in the length direction of the transport table 30, a vertically rotatable roller 32 that is pivotally supported by a U-shaped roller support 34 is provided. In addition, a detachable round bar 36 is erected on the upper surface of both rules of the transport table 30 in order to prevent a loaded transport object from spilling from the transport table 30. In the embodiment, the length of the transport table 30 is 4 meters.

図５に実施例において搬送台３０を搬送路１６に載せた状態の正面図を示す。搬送台３０を搬送路１６に載せるときは、搬送路１６の搬送方向の端で、搬送台３０を、搬送台３０のコロ支持具３４の下部が支柱２０のローラ２２と連結部材４０の突起片４２の間に入るように差し込む。
ここで、連結部材４０に設けられた突起片４２の先端の間隔は搬送台３０のコロ支持具３４の下側の先端の間隔よりも狭く設定されているので、搬送台３０を搬送路１６に載せた状態では、搬送路１６の途中で搬送台３０が搬送路１６から脱落することはない。
なお、搬送の途中で搬送台３０が搬送路１６の片側に寄ったときは、搬送台３０の側面に設けられた自転可能なコロ３２が連結部材４０から搬送路１６の内側に突出した突起片４２に当接し、コロ３２の回転により突起片４２との摩擦抵抗が減少するため、搬送台３０が搬送路１６を移動するときの抵抗の増大を抑えることができる。 FIG. 5 shows a front view of a state in which the transport table 30 is placed on the transport path 16 in the embodiment. When placing the transport table 30 on the transport path 16, at the end in the transport direction of the transport path 16, the lower part of the roller support 34 of the transport table 30 is the roller 22 of the support column 20 and the protruding piece of the connecting member 40. 42 so that it enters between 42.
Here, since the interval between the tips of the protrusions 42 provided on the connecting member 40 is set to be narrower than the interval between the tips on the lower side of the roller support 34 of the conveyance table 30, the conveyance table 30 is moved to the conveyance path 16. In the loaded state, the transport table 30 does not fall off the transport path 16 in the middle of the transport path 16.
In addition, when the conveyance stage 30 approaches one side of the conveyance path 16 in the middle of conveyance, the rotatable roller 32 provided on the side surface of the conveyance stage 30 protrudes from the connecting member 40 to the inside of the conveyance path 16. Since the frictional resistance with the protruding piece 42 decreases due to the rotation of the roller 32, the increase in resistance when the transport table 30 moves along the transport path 16 can be suppressed.

この搬送装置１０は、ローラ２２の回転で搬送台３０が移動する構成であり搬送の負荷は非常に小さいため、搬送のための特別な動力は不要であり、建設資材を積んだ搬送台３０を人力により搬送路１６上で移動させることができる。そこで、積載場所と施工場所の間に搬送路１６を設置し、搬送台３０の両端のロープ孔３９にロープを取付けておけば、積載場所にいる積み込み担当の作業者と施工場所にいる荷下ろし担当の作業者が交互にロープを引いて搬送台３０を引き寄せることで、積載場所の作業者と施工場所の作業者はその場を移動することなく、搬送台３０に建設資材を積載して積載場所と施工場所の間で簡単に搬送台３０を移動させることができる。よって、工事現場で手軽に建設資材を搬送することができる。
実施例では搬送台３０の重量は約１０Ｋｇであり、搬送装置１０によって一度に５００Ｋｇ程度の積載物を搬送することが可能となる。
なお、ロープをブレーキ付のリールに巻き付けて搬送装置１０を使用するとロープの始末がよくなり、搬送台３０の移動の制御を簡単に行うことができるようになる。 The transport device 10 is configured such that the transport base 30 is moved by the rotation of the roller 22 and the load of transport is very small. Therefore, no special power is required for transport, and the transport base 30 loaded with construction materials is removed. It can be moved on the conveyance path 16 by human power. Therefore, if the conveyance path 16 is installed between the loading place and the construction place, and ropes are attached to the rope holes 39 at both ends of the carrying stand 30, the loading operator at the loading place and the unloading at the construction place are unloaded. The worker in charge pulls the rope alternately and pulls the carrier 30 so that the worker at the loading site and the worker at the construction site can load and load the construction material on the carrier 30 without moving on the spot. The carriage 30 can be easily moved between the place and the construction place. Therefore, the construction material can be easily transported at the construction site.
In the embodiment, the weight of the transport table 30 is about 10 kg, and the transport apparatus 10 can transport a load of about 500 kg at a time.
When the rope is wound around a reel with a brake and the conveyance device 10 is used, the rope is properly handled, and the movement of the conveyance table 30 can be easily controlled.

搬送路１６を構成する支柱２０及び連結部材４０は搬送台３０に積載できる大きのため、搬送路１６の設置や撤去にも搬送装置１０を利用することができる。
また、搬送台３０の長さを超える搬送物についても、搬送台３０を２台並べた上に積載することで、搬送することができる。
また、搬送路１６によって隔てられた両側の間で建設資材等を移動させる必要が生じたときは、部分的に連結部材４０と支柱２０を取外して通路を確保することができるので、搬送路１６を迂回する必要がない。
搬送路１６に傾斜がある場合には、高い位置にいる作業者がロープを巻き付けたリールのブレーキを緩めたり、ロープを巻き上げたりして搬送台３０の移動を制御すればよい。なお、搬送台３０を移動させるためのロープの巻き上げは人力に限ったものではなく、ウインチを使用して巻き上げても良い。 Since the support column 20 and the connecting member 40 constituting the conveyance path 16 are large enough to be loaded on the conveyance table 30, the conveyance apparatus 10 can be used to install and remove the conveyance path 16.
In addition, a conveyed product exceeding the length of the transport table 30 can be transported by stacking two transport tables 30 on top of each other.
Further, when it becomes necessary to move the construction material between both sides separated by the conveyance path 16, the connection member 40 and the column 20 can be partially removed to secure the passage, so that the conveyance path 16 can be secured. There is no need to detour.
When the conveyance path 16 is inclined, an operator at a high position may control the movement of the conveyance table 30 by loosening the brake of the reel around which the rope is wound or winding the rope. Note that the hoisting of the rope for moving the transport table 30 is not limited to human power, and may be hoisted using a winch.
