Description

本発明は、道路用の床版およびその施工方法に関する。 The present invention relates to a road slab and its construction method.

道路工事では、工事中の迂回路や建設機械の通路として仮設橋を建設する場合がある。仮設構造物では、恒久的な構造物に比べて耐久性は要求されないが、耐震性は同様に要求される。また、仮設構造物では、設置および撤去が容易であることも求められる。このような要求に対し、仮設橋の上部構造を軽量化することによって、設置および撤去を容易にするとともに、下部構造にかかる地震荷重を低減することができる。上部構造の中でも、床版は死荷重を負担する割合が大きいため、構造の改善が種々検討されている。 During road construction, temporary bridges may be constructed as detours or passageways for construction machinery during construction. Although temporary structures do not have the same durability requirements as permanent structures, they do have similar earthquake resistance requirements. Temporary structures are also required to be easy to install and remove. In response to these demands, by reducing the weight of the upper structure of a temporary bridge, it is possible to facilitate installation and removal and reduce the seismic load applied to the lower structure. Among the superstructures, deck slabs bear a large proportion of the dead load, so various structural improvements are being considered.

例えば、特許文献１には、道路の延長方向（橋軸方向）に延びる複数の角形鋼管を平行に配列し、角形鋼管の側面に設けた開口部に棒状部材を挿通してせん断キーを構成するとともに、角形鋼管と棒状部材との交差部分にコンクリートなどの経時硬化性材料を充填する技術が記載されている。これによって、溶接を使用せずに複数の角形鋼管を接合して床版を構成することができ、設置時の施工性が向上する。 For example, Patent Document 1 discloses that a plurality of square steel pipes extending in the road extension direction (bridge axis direction) are arranged in parallel, and a rod-shaped member is inserted into an opening provided on the side surface of the square steel pipe to constitute a shear key. In addition, a technique is described in which the intersection of a square steel pipe and a rod-shaped member is filled with a material that hardens over time, such as concrete. This allows the deck slab to be constructed by joining a plurality of square steel pipes without using welding, improving workability during installation.

特開２００４－２８５８２３号公報Japanese Patent Application Publication No. 2004-285823

しかしながら、特許文献１に記載された技術では、角形鋼管の内部にコンクリートなどの経時硬化性材料を充填するため、撤去時の施工性は必ずしも高いとはいえない。さらに、迂回路には車両の走行性も求められる。すなわち車両荷重に対して床版が変形した後にも、路面に顕著な凹凸がなく、走行が妨げられないことが求められる。変形後の路面が連続的であることは舗装の劣化も抑制できる。従来の技術ではこうした施工性や走行性の要求に対する解決方法が十分に提供されていない。 However, in the technique described in Patent Document 1, since the inside of the square steel pipe is filled with a material that hardens over time, such as concrete, the workability at the time of removal is not necessarily high. Furthermore, vehicle drivability is also required for detours. In other words, even after the floor slab deforms due to the vehicle load, the road surface is required to have no noticeable irregularities and to not impede driving. Having a continuous road surface after deformation can also suppress pavement deterioration. Conventional technology does not provide sufficient solutions to these requirements for workability and runnability.

そこで、本発明は、設置および撤去の施工性を向上させ、かつ車両の走行性を確保できる道路用の床版およびその施工方法を提供することを目的とする。 SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a road slab and its construction method that can improve installation and removal workability and ensure vehicle drivability.

本発明のある観点によれば、道路用の床版であって、道路の幅方向に架設される複数の横梁部材と、複数の横梁部材の上面に接合されることによって複数の横梁部材を互いに連結し、かつ路面を形成する鋼板とを備える床版が提供される。 According to one aspect of the present invention, the floor slab for a road includes a plurality of cross beam members installed in the width direction of the road, and a plurality of cross beam members that are connected to each other by being joined to the upper surfaces of the plurality of cross beam members. A floor slab is provided that includes steel plates that connect together and form a road surface.

上記の床版において、複数の横梁部材は、互いに離間して配置されてもよい。また、この場合において、複数の横梁部材は、道路の幅方向に沿って拡大または縮小する間隔で配置されてもよい。 In the above floor slab, the plurality of cross beam members may be arranged apart from each other. Moreover, in this case, the plurality of cross beam members may be arranged at intervals that expand or contract along the width direction of the road.

上記の床版において、複数の横梁部材は角形鋼管を含んでもよく、Ｈ形鋼を含んでもよく、また断面形状が互いに異なる部材を含んでもよい。 In the above floor slab, the plurality of cross beam members may include square steel pipes, H-beam steel, or members having different cross-sectional shapes.

上記の床版において、複数の横梁部材の上面と鋼板とは締結手段を用いて接合されていても良い。 In the above floor slab, the upper surfaces of the plurality of cross beam members and the steel plate may be joined using a fastening means.

上記の床版において、鋼板は、道路の延長方向の第１の区間で複数の横梁部材の上面に接合される第１の鋼板と、道路の延長方向の第２の区間で複数の横梁部材の上面に接合される第２の鋼板とを含み、第１の鋼板と第２の鋼板との境目は複数の横梁部材のいずれかの上面に位置してもよい。 In the above deck slab, the steel plates include a first steel plate that is joined to the upper surface of the plurality of cross beam members in the first section in the road extension direction, and a first steel plate that is joined to the upper surface of the plurality of cross beam members in the second section in the road extension direction. and a second steel plate joined to the upper surface, and the boundary between the first steel plate and the second steel plate may be located on the upper surface of any one of the plurality of cross beam members.

上記の床版は、道路の延長方向に架設され、複数の横梁部材の下面に接合される縦梁部材をさらに備えてもよい。 The above-mentioned floor slab may further include a vertical beam member that is constructed in the extending direction of the road and joined to the lower surfaces of the plurality of horizontal beam members.

本発明の別の観点によれば、道路用の床版の施工方法であって、複数の横梁部材を道路の幅方向に架設する工程と、複数の横梁部材の上面に鋼板を接合することによって複数の横梁部材を互いに連結する工程とを含み、路面を舗装する場合には鋼板によって支持される舗装材を施工する工程も含む床版の施工方法が提供される。 According to another aspect of the present invention, there is provided a method for constructing a road slab, which includes the steps of constructing a plurality of cross beam members in the width direction of the road, and joining a steel plate to the upper surface of the plurality of cross beam members. A method for constructing a deck slab is provided, which includes a step of connecting a plurality of cross beam members to each other, and also includes a step of constructing a paving material supported by steel plates when paving a road surface.

上記の床版の施工方法において、複数の横梁部材の上面に鋼板を接合する工程は、複数の横梁部材を架設する工程の前に実施されてもよい。また、鋼板によって支持される舗装材を施工する工程は、前記鋼板または前記鋼板と横梁部材を接合した組立体を道路として使用する位置に設置する工程の前に実施されても良い。 In the above-mentioned floor slab construction method, the step of joining the steel plate to the upper surface of the plurality of cross beam members may be performed before the step of constructing the plurality of cross beam members. Further, the step of constructing the paving material supported by the steel plate may be performed before the step of installing the steel plate or an assembly in which the steel plate and the cross beam member are joined at a position where it will be used as a road.

上記の構成によれば、道路の幅方向に架設される複数の横梁部材を、横梁部材の上面に接合される鋼板を用いて互いに連結するため、例えば溶接や経時硬化性材料の充填などの工程が必要とされず、従って設置および撤去の施工性を向上させることができる。 According to the above configuration, a plurality of cross beam members installed in the width direction of the road are connected to each other using steel plates bonded to the upper surfaces of the cross beam members, so processes such as welding and filling with time-hardening materials are required. Therefore, installation and removal workability can be improved.

以下に添付図面を参照しながら、本発明の好適な実施形態について詳細に説明する。なお、本明細書および図面において、実質的に同一の機能構成を有する構成要素については、同一の符号を付することにより重複説明を省略する。 DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Note that, in this specification and the drawings, components having substantially the same functional configurations are designated by the same reference numerals and redundant explanation will be omitted.

図１は、本発明の第１の実施形態に係る道路用の床版を用いた仮設橋の部分切開斜視図である。図示された例において、仮設橋１は、床版１０と、主桁２０とを含む。床版１０は、道路の幅方向（橋幅方向、図中のｙ方向）に架設される複数の横梁部材１１と、複数の横梁部材１１の上面に接合されることによって複数の横梁部材１１を互いに連結し、かつ路面を形成する鋼板１２とを含む。なお、本明細書において、鋼板１２が路面を形成する、とは、道路を走行する車両等の荷重を支持する面が鋼板１２によって形成されることを意味する。具体的には、鋼板１２の上面に直接車両を走行させても良いし、鋼板１２の上面に舗装材等を敷設し、その上に車両を走行させても良い。 FIG. 1 is a partially cutaway perspective view of a temporary bridge using a road slab according to a first embodiment of the present invention. In the illustrated example, the temporary bridge 1 includes a deck slab 10 and a main girder 20. The floor slab 10 has a plurality of cross beam members 11 installed in the width direction of the road (bridge width direction, y direction in the figure), and is joined to the upper surface of the plurality of cross beam members 11 to connect the plurality of cross beam members 11. and steel plates 12 that are connected to each other and form a road surface. Note that, in this specification, the expression that the steel plate 12 forms a road surface means that the steel plate 12 forms a surface that supports the load of a vehicle or the like traveling on the road. Specifically, a vehicle may be driven directly on the upper surface of the steel plate 12, or a paving material or the like may be laid on the upper surface of the steel plate 12, and the vehicle may be driven on it.

図示された例において、横梁部材１１は角形鋼管である。複数の横梁部材１１は道路の延長方向（橋軸方向、図中のｘ方向）に配列される。なお、本明細書において、角形鋼管は、例えば冷間成形によって加工され、正方形または長方形の角が丸められた断面形状の鋼管を含む。それぞれの横梁部材１１は、主桁２０によって道路の幅方向について３点で支持されている。主桁２０は、図示された例ではＨ形断面であり、上フランジ部分にそれぞれの横梁部材１１が載置される。 In the illustrated example, the cross beam member 11 is a square steel pipe. The plurality of cross beam members 11 are arranged in the road extension direction (bridge axis direction, x direction in the figure). Note that in this specification, a square steel pipe includes a steel pipe processed by, for example, cold forming and having a cross-sectional shape of a square or rectangle with rounded corners. Each cross beam member 11 is supported by main girders 20 at three points in the width direction of the road. The main girder 20 has an H-shaped cross section in the illustrated example, and each cross beam member 11 is placed on the upper flange portion.

鋼板１２は、複数の横梁部材１１の上面に接合される。複数の横梁部材１１に共通の鋼板１２を接合することによって、複数の横梁部材１１を互いに連結し、道路の延長方向について複数の横梁部材１１の変形挙動を連続的にすることができる。鋼板１２の上に舗装材（図示せず）が施工される場合は、舗装材は鋼板１２を介して横梁部材１１によって支持される。路面が鋼板１２の上に形成されるため、道路の延長方向に配列されるそれぞれの横梁部材１１の間は密着していなくてもよく、複数の横梁部材１１は互いに離間して配置されてもよい。 The steel plate 12 is joined to the upper surfaces of the plurality of cross beam members 11. By joining the common steel plate 12 to the plurality of cross-beam members 11, the plurality of cross-beam members 11 can be connected to each other, and the deformation behavior of the plurality of cross-beam members 11 can be made continuous in the extending direction of the road. When a paving material (not shown) is constructed on the steel plate 12, the paving material is supported by the cross beam member 11 via the steel plate 12. Since the road surface is formed on the steel plate 12, the respective cross beam members 11 arranged in the extending direction of the road do not need to be in close contact with each other, and the plurality of cross beam members 11 may be arranged apart from each other. good.

図２は、本発明の第１の実施形態に係る道路用の床版を用いたトンネル内の仮設構造物の断面図である。図示された例において、トンネル２は、床版１０と、覆工体３０と、隔壁４０とを含む。床版１０の構成は上記で図１を参照して説明した例と同様であるが、それぞれの横梁部材１１は、覆工体３０に取り付けられるブラケット３１と、隔壁４０の上面とによって、トンネル幅方向について４点で支持されている。このように、本実施形態に係る道路用の床版１０について、それぞれの横梁部材１１を支持する支持体は限定されず、またそれぞれの横梁部材１１の支持点の数も限定されない。 FIG. 2 is a sectional view of a temporary structure in a tunnel using a road slab according to the first embodiment of the present invention. In the illustrated example, the tunnel 2 includes a floor slab 10, a lining 30, and a partition wall 40. The structure of the floor slab 10 is the same as the example described above with reference to FIG. The direction is supported by four points. In this way, regarding the road slab 10 according to the present embodiment, the supports that support each of the cross beam members 11 are not limited, and the number of support points of each of the cross beam members 11 is also not limited.

上記で説明したような本実施形態に係る床版１０を施工する場合、例えば、まず現場で複数の横梁部材１１を主桁２０（図１の例）、またはブラケット３１および隔壁４０（図２の例）上に架設する工程が実施され、次に、架設された複数の横梁部材１１の上面に鋼板１２を接合することによって複数の横梁部材１１を互いに連結する工程が実施されことによって、図１の例における仮設橋１、または図２の例におけるトンネル２内の仮設構造物が構築される。鋼板１２によって支持される舗装材を施工する工程があってもよい。舗装材は、現場で架設された複数の横梁部材１１に鋼板１２を接合する工程の前に、鋼板１２に施工されていてもよい。 When constructing the floor slab 10 according to the present embodiment as described above, for example, first, a plurality of cross beam members 11 are installed at the site on the main girder 20 (example in FIG. 1), or brackets 31 and bulkheads 40 (example in FIG. 2). Example) The step of constructing the plurality of crossbeam members 11 above is carried out, and then the step of connecting the plurality of crossbeam members 11 to each other by joining the steel plates 12 to the upper surfaces of the plurality of crossbeam members 11 that have been erected is carried out. A temporary bridge 1 in the example of FIG. 2 or a temporary structure inside the tunnel 2 in the example of FIG. 2 is constructed. There may also be a step of constructing the paving material supported by the steel plates 12. The paving material may be applied to the steel plate 12 before the step of joining the steel plate 12 to the plurality of cross beam members 11 constructed on site.

他の例として、例えば工場などで複数の横梁部材１１の上面（または、架設後に上面になる面）に鋼板１２を接合する工程を先に実施し、その後に現場で複数の横梁部材１１および鋼板１２からなる組立体を架設する工程が実施されてもよい。鋼板１２の上面（または、設置後に上面になる面）に舗装材を施工する工程は、工場などで複数の横梁部材１１の上面に鋼板１２を接合する工程の前に実施されてもよい。この場合、架設された複数の横梁部材１１の上面に舗装材が予め施工された鋼板１２が接合される。あるいは、工場などで複数の横梁部材１１の上面に鋼板１２を接合する工程の後に、鋼板１２の上面に舗装材を施工してもよい。 As another example, the step of joining the steel plates 12 to the upper surfaces (or the surfaces that will become the upper surfaces after erection) of the plurality of cross beam members 11 is first carried out in a factory, etc., and then the plurality of cross beam members 11 and the steel plates are joined at the site. A step of erecting an assembly consisting of 12 may be performed. The step of applying a paving material to the upper surface of the steel plate 12 (or the surface that will become the upper surface after installation) may be performed before the step of joining the steel plate 12 to the upper surfaces of the plurality of cross beam members 11 in a factory or the like. In this case, the steel plate 12 on which paving material has been applied in advance is joined to the upper surface of the plurality of horizontal beam members 11 that have been constructed. Alternatively, the paving material may be applied to the upper surface of the steel plate 12 after the step of joining the steel plate 12 to the upper surface of the plurality of cross beam members 11 in a factory or the like.

あるいは、複数の横梁部材１１の上面に舗装材が予め施工された鋼板１２を接合し、その後に複数の横梁部材１１、鋼板１２および舗装材からなる組立体を架設する工程が実施されてもよい。このように、複数の横梁部材１１と鋼板１２との接合や、鋼板１２の上面への舗装材の施工を予め行うことによって、例えば運搬や保管に支障がない大きさの組立体（パネル）を工場などで予め製造して施工現場に搬入し、施工現場での工程を簡略化することができる。 Alternatively, a step of joining the steel plates 12 on which paving material has been previously applied to the upper surfaces of the plurality of cross beam members 11, and then constructing an assembly consisting of the plurality of cross beam members 11, the steel plates 12, and the paving material may be carried out. . In this way, by joining the plurality of cross beam members 11 and the steel plates 12 and applying paving material to the upper surface of the steel plates 12 in advance, it is possible to create an assembly (panel) of a size that does not pose a problem for transportation or storage, for example. It can be manufactured in advance at a factory and delivered to the construction site, simplifying the process at the construction site.

図３～図８は、本発明の第１の実施形態に係る道路用の床版における横梁部材のバリエーションを示す図である。図３は、図１のIII－III線矢視図である（主桁２０の図示は省略している）。図３の例において、横梁部材１１は断面が角丸正方形の角形鋼管である。図示していないが、断面が角丸長方形の角形鋼管を横梁部材に用いてもよい。図４の例において、横梁部材１１ＡはＨ形鋼であり、上面になる上フランジ部分１１１Ａで鋼板１２に接合される。図５の例において、横梁部材１１Ｂはハット形鋼である。図６の例において、横梁部材１１Ｃは溝形鋼である。なお、溝形鋼の横梁部材１１Ｃは、図示された例のように溝形の側面１１１Ｃが鋼板１２に接合されるように配置されてもよいし、あるいは溝形の底面１１２Ｃが鋼板１２に接合されるように配置されてもよい。このように、鋼板１２を介して路面を形成することが可能である限りにおいて横梁部材の断面形状は限定されず、例えば各種の形鋼材を横梁部材に用いることができる。 3 to 8 are diagrams showing variations of the cross beam members in the road slab according to the first embodiment of the present invention. FIG. 3 is a view taken along the line III--III in FIG. 1 (the main girder 20 is not shown). In the example of FIG. 3, the cross beam member 11 is a square steel pipe with a rounded square cross section. Although not shown, a square steel pipe with a rounded rectangular cross section may be used as the cross beam member. In the example of FIG. 4, the cross beam member 11A is an H-beam steel, and is joined to the steel plate 12 at an upper flange portion 111A that becomes the upper surface. In the example of FIG. 5, the cross beam member 11B is a hat-shaped steel. In the example of FIG. 6, the cross beam member 11C is a channel steel. Note that the cross beam member 11C made of channel steel may be arranged such that the channel-shaped side surface 111C is joined to the steel plate 12 as in the illustrated example, or the channel-shaped bottom surface 112C is joined to the steel plate 12. It may be arranged so that As described above, the cross-sectional shape of the cross-beam member is not limited as long as the road surface can be formed through the steel plate 12, and for example, various shaped steel materials can be used for the cross-beam member.

一方、図７の例では、角形鋼管の横梁部材１１とＨ形鋼の横梁部材１１Ａとが道路の延長方向について交互に配置される。また、図８の例では、高さの異なる２種類のＨ形鋼の横梁部材１１Ａ１，１１Ａ２が道路の延長方向について交互に配置される。横梁部材１１Ａ１，１１Ａ２は、それぞれ上面になる上フランジ部分１１１Ａ１，１１１Ａ２で鋼板１２に接合される。主桁２０（図１の例）、またはブラケット３１および隔壁４０（図２の例）による横梁部材１１Ａ１，１１Ａ２の支持のために、高さが小さい横梁部材１１Ａ２の下面になる下フランジ部分１１２Ａ２には、スペーサー１３が介挿される。例えば図７および図８に示された例のように、横梁部材には断面形状が互いに異なる部材が含まれてもよい。 On the other hand, in the example of FIG. 7, the cross beam members 11 made of square steel pipes and the cross beam members 11A made of H-shaped steel are arranged alternately in the extending direction of the road. Moreover, in the example of FIG. 8, two types of horizontal beam members 11A1 and 11A2 made of H-shaped steel having different heights are arranged alternately in the extending direction of the road. The cross beam members 11A1 and 11A2 are joined to the steel plate 12 at upper flange portions 111A1 and 111A2, respectively. In order to support the cross beam members 11A1 and 11A2 by the main girder 20 (example in FIG. 1) or the bracket 31 and bulkhead 40 (example in FIG. 2), the lower flange portion 112A2, which is the lower surface of the cross beam member 11A2 with a small height, is A spacer 13 is inserted. For example, as in the examples shown in FIGS. 7 and 8, the cross beam members may include members having mutually different cross-sectional shapes.

図９～図１２は、本発明の第１の実施形態に係る道路用の床版における横梁部材と鋼板との接合構造のバリエーションを示す断面図である。図９の例では、横梁部材１１の上面から突出するスタッドボルト１１４Ａが鋼板１２に形成された貫通孔に挿通され、ナット１１５をスタッドボルト１１４Ａに螺合させることによって横梁部材１１に鋼板１２が接合される。図１０の例では、横梁部材１１の上面および鋼板１２のそれぞれに貫通孔が形成され、これらの貫通孔に挿通されるボルト１１４Ｂにナット１１５を螺合させることによって横梁部材１１に鋼板１２が接合される。図１１の例では、鋼板１２に形成された貫通孔に、タッピングボルト１１４Ｃを挿通し、横梁部材１１の上面に形成されたねじ孔に螺合させることによって横梁部材１１に鋼板１２が接合される。このように、横梁部材１１と鋼板１２との接合には、例えば鋼板１２に形成された貫通孔に挿通される各種の締結部材を用いることができる。他の締結手段の例として、例えば貫通孔に挿通されるピンを用いてもよい。また、貫通孔に挿通される締結手段以外にも、例えばスナップフィットのような凹凸の組み合わせによる機械式接合によって横梁部材１１と鋼板１２とを接合してもよい。 9 to 12 are cross-sectional views showing variations in the joint structure between the cross beam member and the steel plate in the road slab according to the first embodiment of the present invention. In the example of FIG. 9, a stud bolt 114A protruding from the upper surface of the cross beam member 11 is inserted into a through hole formed in the steel plate 12, and the steel plate 12 is joined to the cross beam member 11 by screwing a nut 115 onto the stud bolt 114A. be done. In the example of FIG. 10, through-holes are formed in the upper surface of the cross-beam member 11 and the steel plate 12, and the steel plate 12 is joined to the cross-beam member 11 by screwing nuts 115 onto bolts 114B inserted into these through-holes. be done. In the example of FIG. 11, the steel plate 12 is joined to the cross beam member 11 by inserting a tapping bolt 114C into a through hole formed in the steel plate 12 and screwing it into a screw hole formed on the upper surface of the cross beam member 11. . In this way, various fastening members that are inserted into through holes formed in the steel plate 12 can be used to join the cross beam member 11 and the steel plate 12, for example. As another example of fastening means, for example, a pin inserted through a through hole may be used. In addition to the fastening means inserted through the through-hole, the cross beam member 11 and the steel plate 12 may be joined by mechanical joining using a combination of concave and convex portions, such as a snap fit.

一方、図１２の例では、横梁部材１１の上面に貫通孔が形成され、鋼板１２には皿孔が形成され、これらの貫通孔および皿孔に挿通される皿型ボルト１１４Ｄにナット１１５を螺合させることによって横梁部材１１に鋼板１２が接合される。この場合、皿型ボルト１１４Ｄが鋼板１２の上面から突出しないため、例えば舗装材１１３が無い、もしくは厚みが小さい場合であっても、路面を平坦に保つことができる。上記の図９～図１１の例では鋼板１２の上面からスタッドボルト１１４Ａ、ボルト１１４Ｂまたはタッピングボルト１１４Ｃの頭部が突出するが、舗装材１１３の厚みが突出高さより大きい場合には路面は平坦に保たれる。なお、角形鋼管の横梁部材１１の内部にナット１１５が配置される図１０および図１２の例では、施工に横梁部材１１の内部を自走するナット締結装置を利用してもよい。 On the other hand, in the example shown in FIG. 12, a through hole is formed in the upper surface of the cross beam member 11, a countersunk hole is formed in the steel plate 12, and a nut 115 is screwed into a countersunk bolt 114D that is inserted through these through holes and the countersunk hole. By matching them together, the steel plate 12 is joined to the cross beam member 11. In this case, since the dish-shaped bolts 114D do not protrude from the upper surface of the steel plate 12, the road surface can be kept flat even if, for example, there is no paving material 113 or the paving material 113 is small. In the examples shown in FIGS. 9 to 11 above, the heads of the stud bolts 114A, bolts 114B, or tapping bolts 114C protrude from the upper surface of the steel plate 12, but if the thickness of the paving material 113 is greater than the protrusion height, the road surface becomes flat. It is maintained. In addition, in the example of FIG. 10 and FIG. 12 in which the nut 115 is arranged inside the cross beam member 11 of a square steel pipe, a nut fastening device that moves automatically inside the cross beam member 11 may be used for construction.

図１３および図１４は、本発明の第１の実施形態に係る道路用の床版における鋼板の接続部分の平面図である。図１３に示された例において、道路の延長方向の第１の区間Ｓ１で複数の横梁部材１１の上面に接合される鋼板１２Ａと、第１の区間Ｓ１に隣接する道路の延長方向の第２の区間Ｓ２で複数の横梁部材１１の上面に接合される鋼板１２Ｂとの境目は、これらの鋼板１２Ａ，１２Ｂが接合される複数の横梁部材１１のいずれかの上面に位置する。すなわち、図示された例では、いずれかの横梁部材１１の上面が、鋼板１２Ａ，１２Ｂの両方に接合される。このように鋼板１２Ａ，１２Ｂを配置することによって、第１の区間Ｓ１と第２の区間Ｓ２との間で複数の横梁部材１１の変形挙動を連続的にすることができる。図１４に示された例では、鋼板１２Ａと鋼板１２Ｂとの境目が横梁部材１１の上面に位置するように配置するのに加えて、道路の幅方向に隣接する鋼板１２の間で、道路の延長方向の鋼板１２の境目が位置する横梁部材１１が異なるように、すなわち、道路の延長方向の鋼板１２の境目が千鳥配置になるように配置することによって、道路の延長方向についての床版１０の剛性を向上させている。 13 and 14 are plan views of a connecting portion of steel plates in a road slab according to the first embodiment of the present invention. In the example shown in FIG. 13, the steel plate 12A is joined to the upper surface of the plurality of cross beam members 11 in the first section S1 in the road extension direction, and the steel plate 12A is joined to the upper surface of the plurality of cross beam members 11 in the first section S1 in the road extension direction, and The boundary with the steel plate 12B joined to the upper surface of the plurality of cross beam members 11 in section S2 is located at the upper surface of any one of the plurality of cross beam members 11 to which these steel plates 12A, 12B are joined. That is, in the illustrated example, the upper surface of one of the cross beam members 11 is joined to both of the steel plates 12A and 12B. By arranging the steel plates 12A and 12B in this manner, the deformation behavior of the plurality of cross beam members 11 can be made continuous between the first section S1 and the second section S2. In the example shown in FIG. 14, in addition to arranging the steel plates 12A and 12B such that the boundary between them is located on the upper surface of the cross beam member 11, the border between the steel plates 12A and 12B is located on the upper surface of the cross beam member 11. By arranging the horizontal beam members 11 where the boundaries of the steel plates 12 in the extension direction are different, that is, by arranging the boundaries of the steel plates 12 in the extension direction of the road in a staggered arrangement, the floor slab 10 in the extension direction of the road is The rigidity is improved.

図１５は、本発明の第１の実施形態に係る道路用の床版を、道路の湾曲部分に配置した例を示す図である。上述のように、本実施形態では道路の延長方向に配列される複数の横梁部材１１が必ずしも互いに略密着していなくてよい。従って、図示された例のような道路の湾曲部分では、複数の横梁部材１１を道路の幅方向に沿って拡大または縮小する間隔で配置することによって、横梁部材１１が配列される方向（道路の延長方向）を湾曲させることができる。 FIG. 15 is a diagram showing an example in which the road slab according to the first embodiment of the present invention is arranged on a curved portion of a road. As described above, in this embodiment, the plurality of cross beam members 11 arranged in the road extension direction do not necessarily have to be in substantially close contact with each other. Therefore, in a curved portion of a road such as the illustrated example, by arranging a plurality of cross beam members 11 at intervals that expand or contract along the width direction of the road, the direction in which the cross beam members 11 are arranged (the direction of the road) (extension direction) can be curved.

図１６は、本発明の第２の実施形態に係る道路用の床版を用いた仮設橋の部分切開斜視図である。図示された例において、仮設橋１Ａは、床版１０Ａと、主桁２０とを含む。床版１０Ａは、上記の第１の実施形態と同様の複数の横梁部材１１および鋼板１２に加えて、縦梁部材１４を含む。縦梁部材１４は、道路の延長方向（橋軸方向、図中のｘ方向）に架設され、複数の横梁部材１１の下面に接合される。 FIG. 16 is a partially cutaway perspective view of a temporary bridge using a road slab according to a second embodiment of the present invention. In the illustrated example, the temporary bridge 1A includes a deck slab 10A and a main girder 20. The floor slab 10A includes a longitudinal beam member 14 in addition to the plurality of horizontal beam members 11 and steel plates 12 similar to those in the first embodiment. The longitudinal beam member 14 is constructed in the extending direction of the road (the bridge axis direction, the x direction in the figure) and is joined to the lower surface of the plurality of horizontal beam members 11.

図示された例において、縦梁部材１４はＨ形鋼であり、上フランジ部分でそれぞれの横梁部材１１に接合される。上述のように、複数の横梁部材１１は上面に共通の鋼板１２が接合されることによって互いに連結され、道路の延長方向について変形挙動が連続的になるが、下面にも共通の縦梁部材１４を接合することによって、このような作用を強化することができる。図示された例において縦梁部材１４および主桁２０はいずれもＨ形鋼であるが、主桁２０が床版１０を支持する機能を有するのに対して、縦梁部材１４は上記のように複数の横梁部材１１を互いに連結する機能を有するため、例えば主桁２０よりも小さい断面のＨ形鋼を用いることができる。 In the illustrated example, the longitudinal beam members 14 are H-beams and are joined to the respective cross beam members 11 at the upper flange portions. As described above, the plurality of horizontal beam members 11 are connected to each other by joining the common steel plate 12 on the upper surface, and the deformation behavior is continuous in the extending direction of the road. This effect can be strengthened by joining the two. In the illustrated example, both the longitudinal beam member 14 and the main girder 20 are made of H-beam steel, but while the main girder 20 has the function of supporting the floor slab 10, the longitudinal beam member 14 has the function of supporting the deck slab 10. Since it has the function of connecting the plurality of cross beam members 11 to each other, it is possible to use, for example, an H-section steel having a smaller cross section than the main girder 20.

図１７Ａ～図１７Ｃは、本発明の第２の実施形態に係る道路用の床版における横梁部材と縦梁部材との接合構造の例を示す図である。図１７Ａは接合構造の平面図であり、図１７Ｂおよび図１７Ｃはそれぞれ図１７ＡのＢ－Ｂ線およびＣ－Ｃ線の断面図である。図示された例では、横梁部材１１の下面と縦梁部材１４とが、横梁部材１１の下面に形成される貫通孔１１６および縦梁部材１４の上面（上フランジ部分）に形成される貫通孔１４１にそれぞれ挿通される締結手段であるボルト１４２およびナット１４３を用いて接合される。なお、例えばタッピングボルトなどの他の締結手段が用いられてもよい。図示された例において、ボルト１４２を締結するためにレンチなどの工具を挿入するアクセスホール１１７は、横梁部材１１の上面で貫通孔１１６に対向する位置に形成される。 17A to 17C are diagrams showing an example of a joint structure between a horizontal beam member and a vertical beam member in a road slab according to a second embodiment of the present invention. FIG. 17A is a plan view of the joining structure, and FIGS. 17B and 17C are cross-sectional views taken along line BB and line CC in FIG. 17A, respectively. In the illustrated example, the lower surface of the horizontal beam member 11 and the vertical beam member 14 are connected to a through hole 116 formed on the lower surface of the horizontal beam member 11 and a through hole 141 formed on the upper surface (upper flange portion) of the vertical beam member 14. They are joined using bolts 142 and nuts 143, which are fastening means that are respectively inserted into the parts. Note that other fastening means such as tapping bolts may also be used. In the illustrated example, an access hole 117 into which a tool such as a wrench is inserted in order to fasten the bolt 142 is formed at a position opposite to the through hole 116 on the upper surface of the cross member 11.

一方、図１７Ａ～図１７Ｃに示された例において、横梁部材１１と鋼板１２とは、横梁部材１１の上面から突出するスタッドボルト１１４Ａを鋼板１２に形成された貫通孔に挿通し、ナット１１５をスタッドボルト１１４Ａに螺合させることによって接合される。図１７Ａに示されるように、横梁部材１１の上面において、スタッドボルト１１４Ａは、アクセスホール１１７とは異なる位置から突出する。従って、スタッドボルト１１４Ａに対応した位置に形成される鋼板１２の貫通孔はアクセスホール１１７には重複しない。このため、図示された例において、横梁部材１１に鋼板１２が接合された後は、アクセスホール１１７が鋼板１２によって塞がれる形になり、連続した路面が形成されるのに加えて、アクセスホール１１７を形成したことによって生じる横梁部材１１の断面欠損部分を補強することができる。 On the other hand, in the example shown in FIGS. 17A to 17C, the cross beam member 11 and the steel plate 12 are connected by inserting a stud bolt 114A protruding from the upper surface of the cross beam member 11 into a through hole formed in the steel plate 12, and then tightening a nut 115. It is joined by screwing into the stud bolt 114A. As shown in FIG. 17A, on the upper surface of the cross beam member 11, the stud bolt 114A protrudes from a position different from the access hole 117. Therefore, the through hole of the steel plate 12 formed at the position corresponding to the stud bolt 114A does not overlap the access hole 117. Therefore, in the illustrated example, after the steel plate 12 is joined to the cross beam member 11, the access hole 117 is closed by the steel plate 12, and a continuous road surface is formed. It is possible to reinforce the section-deficient portion of the cross-beam member 11 caused by forming the cross-beam member 117.

図１８Ａ～図１８Ｃは、図１７Ａ～図１７Ｃに示した接合構造においてアクセスホールの位置を変更した例を示す図である。図示された例では、アクセスホール１１７が、横梁部材１１の上面で貫通孔１１６に対向しない位置に形成される。これによって、上述のように鋼板１２によって横梁部材１１の断面欠損部分が補強されるのに加えて、横梁部材１１において貫通孔１１６およびアクセスホール１１７の両方が形成される断面が発生するのを避けることができ、貫通孔１１６およびアクセスホール１１７の形成による横梁部材１１の断面欠損自体を最小限に抑えることができる。鋼板１２による補強で断面欠損が問題にならない程度である場合、アクセスホール１１７の位置は例えばボルト１４２を締結するためのレンチなどの工具の形状に応じて決定されてもよい。 18A to 18C are diagrams showing examples in which the positions of access holes are changed in the joining structures shown in FIGS. 17A to 17C. In the illustrated example, the access hole 117 is formed on the upper surface of the cross beam member 11 at a position that does not face the through hole 116. As a result, in addition to reinforcing the cross-sectional defect portion of the cross-beam member 11 with the steel plate 12 as described above, it is also possible to avoid the occurrence of a cross-section in which both the through-hole 116 and the access hole 117 are formed in the cross-beam member 11. Therefore, the cross-sectional loss of the cross beam member 11 due to the formation of the through hole 116 and the access hole 117 can be minimized. If the reinforcement by the steel plate 12 does not cause cross-sectional defects, the position of the access hole 117 may be determined depending on the shape of a tool such as a wrench for tightening the bolt 142, for example.

以上で説明したような本発明の実施形態、およびその変形例によれば、道路用の床版の全体が鋼部材で形成されるため、例えばコンクリート床版を用いる場合に比べて同程度の剛性を確保しつつ床版を軽量化することができる。また、横梁部材や鋼板といった単位部材が軽量であるため、架設時の施工性が高い。単位部材の種類が少ないため、部材の製造や管理を効率化することができる。加えて、単位部材間で溶接や経時硬化性材料の充填などの工程を必要としないため、撤去時の施工性も高い。 According to the embodiments of the present invention and their modifications as explained above, the entire road slab is formed of steel members, so that it has the same degree of rigidity as, for example, when using a concrete slab. It is possible to reduce the weight of the floor slab while ensuring the same. Furthermore, since unit members such as cross beam members and steel plates are lightweight, workability during erection is high. Since there are fewer types of unit parts, manufacturing and management of parts can be made more efficient. In addition, there is no need for processes such as welding or filling with time-hardening materials between unit members, making it highly workable during removal.

図１９および図２０は、本発明の実施形態に係る道路用の床版の構造的な利点について説明するための図である。図１９は、鋼板を設置せず、道路の延長方向に配列した角形鋼管の横梁部材９１を所定の本数ごとに溶接などによって互いに接合してパネル９２にした参考例を示す図であり、図２０は本発明の実施形態において鋼板１２を接合することによって横梁部材１１を互いに連結した例を示す図である。 FIGS. 19 and 20 are diagrams for explaining the structural advantages of the road slab according to the embodiment of the present invention. FIG. 19 is a diagram showing a reference example in which a predetermined number of cross beam members 91 made of square steel pipes arranged in the extending direction of the road are joined together by welding or the like to form a panel 92 without installing a steel plate. 1 is a diagram showing an example in which cross beam members 11 are connected to each other by joining steel plates 12 in an embodiment of the present invention.

図１９に示す参考例の場合、互いに接合されてパネル９２を構成する横梁部材９１の間では変形挙動が連続的になるが、パネル９２同士の間の境目では、互いに接合されていない横梁部材９１の間での変形挙動が連続的にならない。つまり、パネル９２同士の間の境目に位置する横梁部材９１の間でたわみ変形量に差が生じた場合、床版上面の形状が不連続になる。このような不連続部が生じることによって、例えば床版上面に施工される舗装材に割れが生じたり、道路の走行性が低下したりする可能性がある。 In the case of the reference example shown in FIG. 19, the deformation behavior is continuous between the cross beam members 91 that are joined to each other to form the panel 92, but at the boundary between the panels 92, the cross beam members 91 that are not joined to each other The deformation behavior between the two is not continuous. In other words, if a difference occurs in the amount of deflection deformation between the horizontal beam members 91 located at the boundaries between the panels 92, the shape of the upper surface of the floor slab becomes discontinuous. The occurrence of such a discontinuous portion may cause cracks in the paving material applied to the upper surface of the deck slab, or may reduce the running performance of the road.

一方、図２０に示す本発明の実施形態の場合、複数の横梁部材１１の上面に共通の鋼板１２が接合されることから、それぞれの横梁部材１１の間でたわみ変形量に差が生じたとしても、隣接する横梁部材１１の間で変形挙動は連続的になる。上述のように、鋼板１２の接続部分でも、鋼板１２同士の境目を横梁部材１１の上面に位置させることによって、複数の横梁部材１１の変形挙動を連続的にすることができる。横梁部材１１の変形挙動が連続的であれば、床版上面に施工される舗装材が変形に追従することが可能であるため、舗装材の割れや道路の走行性の低下を防ぐことができる。 On the other hand, in the case of the embodiment of the present invention shown in FIG. 20, since a common steel plate 12 is joined to the upper surface of a plurality of cross beam members 11, it is assumed that there is a difference in the amount of deflection deformation between the respective cross beam members 11. Also, the deformation behavior between adjacent cross beam members 11 is continuous. As described above, by locating the boundary between the steel plates 12 at the upper surface of the cross-beam member 11 at the connection portion of the steel plates 12, the deformation behavior of the plurality of cross-beam members 11 can be made continuous. If the deformation behavior of the cross beam member 11 is continuous, the paving material installed on the top surface of the deck can follow the deformation, so it is possible to prevent cracking of the paving material and deterioration of road running performance. .
