Description

本発明は、例えば、高速道路、高速鉄道、高架橋、一般橋梁等（以下これらを「橋梁」という）の橋軸直角方向側方（路肩より外側）に設置されるコンクリート壁高欄の施工方法と、壁高欄に関する。   The present invention is, for example, a method for constructing a railing for a concrete wall installed on the side perpendicular to the bridge axis (outside the road shoulder) of a highway, a high-speed railway, a viaduct, a general bridge (hereinafter referred to as “bridge”), Concerning wall rails.

橋梁の橋軸直角方向両端には、車両の転落や逸脱を防止する高欄（壁高欄）が橋軸方向に沿って設置されている。従来、壁高欄の施工方法としては、コンクリート床版や鋼床版の上に配設した鉄筋の周囲を型枠で囲み、当該型枠内にコンクリートを打設する方法（いわゆる現場打ち）が一般的であった。しかし、現場打ちでは、鉄筋の配置（配筋）や型枠の設置、コンクリートの打設、打設コンクリートの養生に時間がかかるため、施工期間が長期化するという問題があった。   At both ends of the bridge in the direction perpendicular to the bridge axis, rails (wall rails) are installed along the bridge axis direction to prevent the vehicle from falling or departing. Conventionally, as a method for constructing a wall rail, a method of placing concrete around a reinforcing bar placed on a concrete slab or steel slab with a formwork and placing concrete in the formwork (so-called on-site casting) is generally used. It was the target. However, there is a problem that the construction period is prolonged because it takes time to place reinforcing bars (bar arrangement), formwork, concrete placement, and concrete curing.

この問題を解決するため、近年では予め工場で生産したプレキャストコンクリート壁高欄を現場に運搬して施工するプレキャスト工法が提案されている（特許文献１及び２）。プレキャスト工法によれば、現場打ちするコンクリートの量を最小限に抑えることができるため、施工の急速化（工期短縮）を図ることができる。   In order to solve this problem, in recent years, a precast construction method has been proposed in which a precast concrete wall rail produced in advance in a factory is transported to the work site (Patent Documents 1 and 2). According to the precast method, the amount of concrete to be cast on site can be minimized, so that the construction can be accelerated (shortening the construction period).

特開２０１５−１７８７１０号公報JP2015-178710A 特開２０１３−３６２０５号公報JP2013-36205A

前記特許文献１記載の工法は、工期短縮という点では優れているが、当該工法により得られる壁高欄は衝突時の抵抗力（耐荷力）という点で改善の余地がある。   Although the construction method described in Patent Document 1 is excellent in terms of shortening the construction period, the wall rail obtained by the construction method has room for improvement in terms of the resistance force (load bearing capacity) at the time of collision.

前記特許文献２記載の工法は、床版上側に立設された複数の鉄筋がプレキャスト壁材下側の複数の下向き鉄筋に互いに干渉しないように配置されるようにしなければならないため位置合せが難しく、急速施工を阻害するおそれがある。また、鉄筋によるループ継手による接合ということで上下部の壁高欄を結ぶ間詰め部の体積が大きくそのため現場接合に多大な時間を要していた。   The method described in Patent Document 2 is difficult to align because the plurality of reinforcing bars erected on the upper side of the floor slab must be arranged so as not to interfere with the plurality of downward reinforcing bars below the precast wall material. There is a risk of impeding rapid construction. In addition, the volume of the space between the upper and lower wall rails is large due to the joining by means of the loop joint with the reinforcing bars, and therefore it takes a lot of time for the on-site joining.

本発明の解決課題は、前記両工法の有する課題を解決可能な壁高欄施工方法と、前記両工法により得られる壁高欄の有する課題を解決可能な壁高欄を提供することにある。   The problem to be solved by the present invention is to provide a wall rail construction method capable of solving the problems of the two methods and a wall rail capable of solving the problems of the wall rails obtained by the two methods.

（壁高欄施工方法の実施形態１）
本発明の壁高欄施工方法の第一の実施形態を、図面を参照して説明する。この実施形態の壁高欄施工方法は、プレキャスト下部高欄１の上側にプレキャスト上部高欄２を配置する工程（高欄配置工程）と、所定空隙に間詰め材３を充填する工程（間詰め材充填工程）と、間詰め材３を所定時間養生し硬化する工程（養生工程）を備えている。ここでは、一本の直線状の凹溝４を備えたプレキャスト下部高欄１と複数本の突部材５を備えたプレキャスト上部高欄２を用いる場合を一例として説明する。なお、本願におけるプレキャスト下部高欄１及びプレキャスト上部高欄２は、予め工場で生産したプレキャストコンクリート製品である。 (Embodiment 1 of wall railing construction method)
1st embodiment of the wall railing construction method of this invention is described with reference to drawings. The wall railing construction method of this embodiment includes a step of placing the precast upper rail 2 on the upper side of the precast lower rail 1 (a rail placement step), and a step of filling the predetermined gap with the filling material 3 (filling material filling step). And a step (curing step) for curing and curing the filling material 3 for a predetermined time. Here, the case where the precast upper rail 1 provided with the one linear groove 4 and the precast upper rail 2 provided with the several protrusion member 5 is demonstrated as an example. In addition, the precast lower balustrade 1 and the precast upper balustrade 2 in this application are the precast concrete products produced beforehand in the factory.

図１（ａ）〜（ｃ）及び図２（ａ）〜（ｃ）に示すように、この実施形態のプレキャスト下部高欄１は、床版部１ａと地覆部（路肩より外側で路面より高くなっている部分）１ｂを備えている。床版部１ａは鉄筋コンクリート製であっても、鋼製であってもよい。プレキャスト下部高欄１の地覆部１ｂの上面には断面視縦長方形状の凹溝４が設けられている。凹溝４は前記プレキャスト上部高欄２に設けられた突部材５が収まる空間である。この実施形態の凹溝４は橋軸方向に長い長溝である。凹溝４はプレキャスト下部高欄１の橋軸方向全長に及ぶ長さとしてある。凹溝４の深さは突部材５の半分程度が収まる深さとしてある。凹溝４は地覆部１ｂの上面の幅方向中心付近に設けてある。凹溝４の長さや深さ、形成位置はこれ以外であってもよい。   As shown in FIGS. 1 (a) to 1 (c) and FIGS. 2 (a) to (c), the precast lower rail 1 of this embodiment has a floor slab 1a and a ground cover (on the outside of the road shoulder and higher than the road surface). Part 1b provided. The floor slab portion 1a may be made of reinforced concrete or steel. On the upper surface of the ground cover portion 1b of the precast lower rail 1 is provided a concave groove 4 having a vertical rectangular shape in cross section. The concave groove 4 is a space in which the protruding member 5 provided in the precast upper rail 2 is accommodated. The concave groove 4 of this embodiment is a long groove long in the bridge axis direction. The concave groove 4 has a length extending over the entire length of the precast lower rail 1 in the bridge axis direction. The depth of the recessed groove 4 is set to a depth that can accommodate about half of the protruding member 5. The concave groove 4 is provided in the vicinity of the center in the width direction of the upper surface of the ground covering portion 1b. The length, depth, and formation position of the groove 4 may be other than this.

プレキャスト下部高欄１の地覆部１ｂの上面には高さ調整ボルト６が上向きに突設されている。あるいは、高さ調整ボルト６はあらかじめプレキャスト上部高欄２に埋設された高さ調整用インサート７に螺合してきても良い。高さ調整ボルト６はプレキャスト上部高欄２に埋設された高さ調整用インサート７に螺合して、プレキャスト上部高欄２の高さを調整するものである。図１（ｂ）及び図２（ｂ）に示すように、高さ調整ボルト６は、プレキャスト下部高欄１を正面から見た際に凹溝４の幅方向両外側に設けられている。高さ調整ボルト６は橋軸方向に沿って複数個ずつ設けられている。高さ調整ボルト６の設置位置や設置個数は、プレキャスト下部高欄１内に配筋された鉄筋Ｘの位置等に応じて決定することができる。   A height adjusting bolt 6 is projected upward on the upper surface of the ground cover portion 1b of the precast lower rail 1. Alternatively, the height adjusting bolt 6 may be screwed into the height adjusting insert 7 embedded in the precast upper column 2 in advance. The height adjusting bolt 6 is screwed into a height adjusting insert 7 embedded in the precast upper column 2 to adjust the height of the precast upper column 2. As shown in FIGS. 1B and 2B, the height adjusting bolts 6 are provided on both outer sides in the width direction of the groove 4 when the precast lower rail 1 is viewed from the front. A plurality of height adjustment bolts 6 are provided along the bridge axis direction. The installation position and the number of installation of the height adjusting bolts 6 can be determined according to the position of the reinforcing bar X arranged in the precast lower rail 1 or the like.

プレキャスト下部高欄１は橋軸方向に並べて、隣接するプレキャスト下部高欄１同士を一体化して使用する。橋軸方向に隣接するプレキャスト下部高欄１同士は、図３（ａ）（ｂ）に示すように橋軸方向に隣接するプレキャスト下部高欄１同士を一体化することができる。プレキャスト下部高欄１同士の一体化には鉄筋Ｘと間詰め材Ｙを利用する。間詰め材Ｙには、プレキャスト下部高欄１とプレキャスト上部高欄２の一体化に用いる間詰め材３を用いることができる。   The precast lower rails 1 are arranged in the direction of the bridge axis, and adjacent precast lower rails 1 are integrated and used. As shown in FIGS. 3A and 3B, the precast lower height rails 1 adjacent to each other in the bridge axis direction can be integrated with each other. Reinforcing bars X and padding material Y are used for the integration of the precast lower rail 1. As the interlining material Y, the interlining material 3 used for integrating the precast lower balustrade 1 and the precast upper balustrade 2 can be used.

図１（ａ）〜（ｃ）及び図２（ａ）〜（ｃ）に示すように、この実施形態のプレキャスト上部高欄２は、プレキャスト下部高欄１の地覆部１ｂの上に配置される部材である。プレキャスト上部高欄２の底面には一列に並ぶ複数本の突部材５が下向きに突設されている。この実施形態では、突部材５として異形棒鋼（例えば、異形棒鋼Ｄ４１）５ａの上下両端寄りの箇所にナット５ｂが螺合されたものを用いている。ナット５ｂは引抜抵抗力を増すために設けており、突部材５に十分な付着力がある場合や高欄の設計断面力が小さな場合は、これを省いても良い。異形棒鋼５ａの太さはこれより細くても太くてもよい。突部材５の本数は、その突部材５の太さや凹溝４の長さ等に応じて決定することができる。突部材５には、異形棒鋼のほか丸鋼や鋼管などを用いることもできる。突部材５として鋼管を用いる場合、周面に肉厚方向に貫通する貫通孔を備えたものを用いることもできる。突部材５として貫通孔を備えた鋼管を用いる場合、間詰め材３が鋼管の内部にも充填されるため、引抜抵抗力及び耐荷力が向上する。鉄筋（異形棒鋼や丸鋼）は鋼管に比して低額であるため、鉄筋を用いることで、コストを抑えることができる。   As shown in FIGS. 1A to 1C and FIGS. 2A to 2C, the precast upper rail 2 of this embodiment is a member disposed on the ground cover portion 1b of the precast lower rail 1. It is. A plurality of projecting members 5 arranged in a row project downward from the bottom surface of the precast upper rail 2. In this embodiment, as the protruding member 5, a deformed steel bar (for example, a deformed steel bar D41) 5a is used in which nuts 5b are screwed at positions near both upper and lower ends. The nut 5b is provided to increase the pulling resistance, and may be omitted when the protruding member 5 has a sufficient adhesion force or when the design cross-sectional force of the rail is small. The thickness of the deformed bar 5a may be thinner or thicker than this. The number of the projecting members 5 can be determined according to the thickness of the projecting member 5, the length of the concave groove 4, and the like. As the projecting member 5, a round steel bar, a steel pipe, etc. can be used in addition to a deformed bar steel. When a steel pipe is used as the projecting member 5, it is possible to use one having a through-hole penetrating in the thickness direction on the peripheral surface. When a steel pipe provided with a through hole is used as the projecting member 5, the filling material 3 is also filled into the steel pipe, so that the pulling resistance and load resistance are improved. Reinforcing bars (deformed bar steel and round steel) are less expensive than steel pipes, so the cost can be reduced by using reinforcing bars.

プレキャスト上部高欄２の底面には、プレキャスト下部高欄１に設けられた高さ調整ボルト６を螺合可能な高さ調整用インサート７が埋設されている。高さ調整用インサート７は高さ調整ボルト６に対応する位置に、対応する数だけ設けてある。なお、高さ調整ボルト６や高さ調整用インサート７がなくても適切な高さ調整ができる場合には、これらを省略することができる。   A height adjusting insert 7 capable of screwing a height adjusting bolt 6 provided in the precast lower height column 1 is embedded in the bottom surface of the precast upper height column 2. A corresponding number of height adjusting inserts 7 are provided at positions corresponding to the height adjusting bolts 6. In addition, when an appropriate height adjustment can be performed without the height adjustment bolt 6 and the height adjustment insert 7, these can be omitted.

前記高欄配置工程では、図２（ｂ）及び図４（ａ）に示すように、前記プレキャスト上部高欄２の突部材５がプレキャスト下部高欄１の凹溝４に収まるように、プレキャスト上部高欄２をプレキャスト下部高欄１の上側に配置する。この実施形態では、一本の直線状の凹溝４に一列に並んだ複数本の突部材５を収めればよいため、位置合わせが簡単であり、急速施工を阻害することがない。また、凹溝４と部材間空隙８を連通するようにして、双方に一度に間詰め材３を充填できるようにしてあるため、充填時間の短縮、ひいては施工期間の短縮を図ることができる。なお、高さ調整が必要な場合は、プレキャスト上部高欄２をプレキャスト下部高欄１の上側に配置した後、高さ調整ボルト６の高さ調整用インサート７への螺合量を調整する。   In the rail arrangement step, as shown in FIGS. 2 (b) and 4 (a), the precast upper rail 2 is placed so that the protruding member 5 of the precast upper rail 2 fits in the groove 4 of the precast lower rail 1. It is arranged above the precast lower rail 1. In this embodiment, it is only necessary to store a plurality of projecting members 5 arranged in a line in one linear concave groove 4, so that the alignment is simple and rapid construction is not hindered. Further, since the groove 4 and the inter-member gap 8 are communicated with each other so that the filling material 3 can be filled at the same time, it is possible to shorten the filling time and hence the construction period. In addition, when height adjustment is required, after arrange | positioning the precast upper height column 2 above the precast lower height column 1, the screwing amount to the height adjustment insert 7 of the height adjustment bolt 6 is adjusted.

前記高欄配置工程の完了後、間詰め材充填工程では、図２（ｃ）及び図４（ｂ）に示すように、突部材５が収まった凹溝４及び凹溝４と連通する部材間空隙８に間詰め材３を充填する。間詰め材３には、モルタルやコンクリート等を用いることができる。間詰め材３は、プレキャスト下部高欄１やプレキャスト上部高欄２を構成するコンクリートよりも強度の低いものを用いることができる。間詰め材３としてプレキャスト下部高欄１やプレキャスト上部高欄２を構成するコンクリートよりも強度の低いものを用いることで、車両衝突時に間詰め材３が衝撃を吸収して、プレキャスト下部高欄１やプレキャスト上部高欄２自体が損傷するのを防止することができる。間詰め材３は、プレキャスト下部高欄１やプレキャスト上部高欄２を構成するコンクリートの強度と同じ又はそれよりも強度の高いものを用いることもできる。間詰め材３には、じん性に富む短繊維が混入された（短繊維補強された）モルタルやコンクリートを用いることもできる。短繊維が混入された間詰め材によってエネルギーの消費量を増やすことができ、より衝撃を吸収することが可能である。この実施形態では、間詰め材３として無収縮モルタルを用いている。なお、図示は省略しているが、本工程では、間詰め材３の充填に先立って間詰め材充填領域の周囲に型枠を設置する。   After completion of the railing arrangement step, in the filling material filling step, as shown in FIGS. 2 (c) and 4 (b), the concave groove 4 in which the protruding member 5 is accommodated and the inter-member gap communicating with the concave groove 4 8 is filled with the filling material 3. As the filling material 3, mortar, concrete, or the like can be used. As the filling material 3, a material having lower strength than the concrete constituting the precast lower rail 1 or the precast upper rail 2 can be used. By using a material having lower strength than the concrete constituting the precast lower rail 1 or the precast upper rail 2 as the spacing material 3, the spacing material 3 absorbs an impact at the time of a vehicle collision, and the precast lower rail 1 or the precast upper The rail 2 itself can be prevented from being damaged. As the filling material 3, a material having the same or higher strength than the concrete constituting the precast lower rail 1 or the precast upper rail 2 can be used. As the filling material 3, mortar or concrete mixed with short fibers rich in toughness (reinforced with short fibers) can also be used. Energy consumption can be increased by the interstitial material mixed with the short fibers, and more impact can be absorbed.
