Description

本発明は、道路橋の継手の構造に関するものである。   The present invention relates to a structure of a joint for a road bridge.

コンクリート床版で構成した道路橋は、コンクリートの伸縮を吸収するために継手部に間隔を設けてある。
しかしその間隔から雨水などが落下しては不都合なので、落下しないような工夫を施してある。
例えば図6に示すように、床版コンクリートaの端面の鋼製の端面板bの間の継手部cに伸縮性の膜dを取り付けたり、シール材を充填して構成している。
The road bridge composed of concrete floor slabs has a gap in the joint to absorb the expansion and contraction of the concrete.
However, since it is inconvenient if rainwater falls from the interval, it is designed not to fall.
For example, as shown in FIG. 6, a stretchable film d is attached to a joint portion c between steel end plates b on the end surface of the floor slab concrete a, or a sealing material is filled.

特許3442362号公報Japanese Patent No. 3442362

前記したような従来の道路橋の継手の構造にあっては、次のような問題点がある。   The conventional road bridge joint structure as described above has the following problems.

まず、継手部の端面板bを鋼製の板材で構成したことによる問題は以下の通りである。
<1> 継手の端面板bが鋼製の板材であるために大きい耐摩耗性を備えている。
<2> 一方、コンクリート版aの路面やその上の舗装面はタイヤの通過、打撃で摩耗しやすい。
<3> そのために、摩耗しにくい鋼製の端面板bと、コンクリートaとの間に、図7に示すように、摩耗の結果による段差が生じてしまう。
<4> すると、先に摩耗したり破損したコンクリートaと、摩耗の遅れる鋼製の端面板bとの段差で、端面板bが突出した状態となり、その端面板bの側面に、通行する自動車のタイヤが乗り上げてジャンプして落下する。その繰り返しの衝撃によってコンクリートaが損傷を受け続ける。
<5> その繰り返しの打撃によって、コンクリートaが損傷を受けると、コンクリートaの摩耗部分に雨水が溜まり、溜まった水が端面板bとの隙間から浸入して、端面板bを錆びさせる結果となる。
<6> 特に凍結防止のために塩を散布する地域では、塩分がコンクリートaと鋼製の端面板bとの隙間に浸入して鋼材の腐食を早める。
First, problems due to the fact that the end face plate b of the joint portion is made of a steel plate material are as follows.
<1> Since the end face plate b of the joint is a steel plate material, it has high wear resistance.
<2> On the other hand, the road surface of the concrete plate a and the paved surface thereon are easily worn by passing and hitting the tire.
<3> Therefore, as shown in FIG. 7, the level | step difference by the result of abrasion will arise between the steel end surface board b which is hard to wear, and the concrete a.
<4> Then, the end plate b protrudes at the level difference between the worn or damaged concrete a and the steel end plate b that is delayed in wear, and the vehicle passes through the side surface of the end plate b. Tires jump on and jump and fall. The concrete a continues to be damaged by the repeated impact.
<5> When the concrete a is damaged due to repeated hitting, rain water accumulates in the worn part of the concrete a, and the accumulated water enters through the gap between the end face plate b and causes the end face plate b to rust. Become.
<6> Particularly in an area where salt is sprayed to prevent freezing, salt enters the gap between the concrete a and the steel end plate b to accelerate corrosion of the steel material.

次に継手部の止水の問題は次の通りである。
<1> 従来の継手の止水は、継手間に充填した膨張材や、図6に示すように両者間に張り渡した伸縮膜dによって行っている。
<2> この伸縮膜dが破損した場合に、交換する必要があるが、破損した膜dの撤去と新たな膜dの取り付けを行う際に、わずか数cmの狭い継ぎ目の隙間から行なわなければならず、非常に困難な作業であり、信頼性の低いものだった。
<3> さらに伸縮膜dの両端部を、鉛直な端面板dに取り付けているだけであるから、冬季にコンクリートaが収縮して継手部cの間隔が開くと、剥離しやすい構造であった。
Next, the problem of water stoppage at the joint is as follows.
<1> The water stop of a conventional joint is performed by an expansion material filled between the joints or a stretchable film d stretched between the two as shown in FIG.
<2> When this stretchable membrane d is damaged, it is necessary to replace it. However, when removing the damaged membrane d and attaching a new membrane d, it must be performed from a gap of a narrow seam of only a few cm. It was very difficult and unreliable.
<3> Furthermore, since both ends of the stretchable film d are only attached to the vertical end plate d, the structure is easy to peel off when the concrete a contracts and the interval between the joints c opens in winter. .

上記のような課題を解決するために、本発明の道路橋の継手の構造は、道路橋のコンクリート床版の道路の中心軸横断方向の端面を、曲線を連続した鉛直曲面によって構成し、その表面はFRPの鉛直面で構成し、FRP板の鉛直曲面の背面には控え板を突出し、控え板はコンクリートの内部に配置したものである。
そしてFRP板の鉛直曲面の背面、控え板の表面には砂などの粒子を接着剤で塗布してコンクリートとの付着を大きくする。
また本発明の道路橋の継手の構造は、道路橋のコンクリート床版の道路の中心軸横断方向の端面を、曲線を連続した鉛直曲面によって構成し、その表面のFRP製の鉛直曲面には、水平方向に係合溝を連続して形成し、ひとつのコンクリート床版を隣接するコンクリート床版と端面を対向して設置した場合に、一方の鉛直曲面の係合溝と他方の鉛直曲面の係合溝は対向する位置に配置し、両側の係合溝の内部に断面V字形の止水ゴムの折り返し端部を嵌合し得るように構成したものである。
In order to solve the above-described problems, the road bridge joint structure of the present invention is configured such that the end surface in the direction crossing the central axis of the road of the concrete floor slab of the road bridge is constituted by a continuous vertical curved surface. The surface is composed of a vertical surface of the FRP, and a back plate protrudes from the back surface of the vertical curved surface of the FRP plate, and the back plate is disposed inside the concrete.
Then, particles such as sand are applied with an adhesive on the back surface of the vertical curved surface of the FRP plate and the surface of the back plate to increase the adhesion to the concrete.
Moreover, the structure of the joint of the road bridge of the present invention is configured such that the end surface in the direction of the center axis of the road of the concrete floor slab of the road bridge is constituted by a continuous curved vertical curve, When engaging grooves are continuously formed in the horizontal direction and one concrete floor slab is installed with the adjacent concrete floor slab facing the end surface, the relationship between the engaging groove of one vertical curved surface and the other vertical curved surface The mating grooves are arranged at opposing positions, and are configured so that folded ends of water-stopping rubber having a V-shaped cross section can be fitted inside the engaging grooves on both sides.

本発明の道路橋の継手の構造は以上説明したようになるから次のような効果を得ることができる。
まずFRP板を使用したための効果は次の通りである。
<1> FRP製の鉛直曲面は、摩擦に対する抵抗が大きくないから、コンクリートの摩耗とともに摩耗してゆき、鋼板のように突出することがない。
<2> そのためにコンクリートとの一体化が維持され、隙間が生じたり、その隙間に雨水や塩水が浸入することがない。
<3> 鋼板と異なって塩水によっても腐食することがない。
<4> 軽量であるから、設置作業、交換作業が容易である。
Since the structure of the joint of the road bridge of the present invention is as described above, the following effects can be obtained.
First, the effect of using the FRP plate is as follows.
<1> Since the FRP vertical curved surface does not have a large resistance to friction, it wears with the wear of concrete and does not protrude like a steel plate.
<2> Therefore, integration with concrete is maintained, and no gap is formed, and rainwater and salt water do not enter the gap.
<3> Unlike steel sheets, it is not corroded by salt water.
<4> Since it is lightweight, installation work and replacement work are easy.

また係合溝を設けたための効果は次の通りである。
<1> わずか数cmの狭い隙間からの止水帯の撤去も嵌合も、すべて鉛直方向の作業であるから、作業が容易であり、嵌合後の信頼性が高い。
<2> 係合溝が鉛直方向に形成してあるから、冬季に鉛直面間の間隔が開いた場合にも止水帯が鉛直面から剥離することがない。
<3> したがって長期にわたって継手部分における止水性について、高い信頼性を維持できる。
The effects of providing the engaging groove are as follows.
<1> Since the removal and fitting of the waterstop from a narrow gap of only a few centimeters are all work in the vertical direction, the work is easy and the reliability after fitting is high.
<2> Since the engagement groove is formed in the vertical direction, the waterstop does not peel from the vertical surface even when the interval between the vertical surfaces is opened in winter.
<3> Therefore, high reliability can be maintained for the water stoppage at the joint portion over a long period.

以下図面を参照にしながら本発明の好適な実施の形態を詳細に説明する。   DESCRIPTION OF EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

<1>前提条件
本願発明は、道路橋の継手の構造に関するものである。
道路橋のコンクリート床版1は図1に示すように橋脚Aの上に配置した鋼材の桁Bの上に設置してある。
そして隣接するコンクリート床版1との継手部分は、コンクリート床版1の伸縮を吸収できるだけの隙間を介在して位置している。
本発明は、このコンクリート床版1の端面である継手部分の改良に関するものである。
<1> Precondition The present invention relates to the structure of a joint for a road bridge.
A concrete floor slab 1 of a road bridge is installed on a steel beam girder B arranged on a pier A as shown in FIG.
And the joint part with the adjacent concrete floor slab 1 is located through the gap which can absorb the expansion and contraction of the concrete floor slab 1.
The present invention relates to an improvement of a joint portion which is an end face of the concrete floor slab 1.

<2>鉛直曲面
本発明のコンクリート床版1では、その道路の中心軸方向と直交する端面である継ぎ目を、曲線を連続した鉛直曲面2によって構成する。
そして、実際に道路橋として鋼材の桁Bの上に設置する場合には、一方のコンクリート床版1の鉛直曲面2の凹部を、隣接する他方のコンクリート床版1の鉛直曲面2の凸部に組み合わせ、隙間を介して対向する状態で設置する。
あるいは一方のコンクリート床版1の鉛直曲面2を、橋台側の継手の鉛直曲面2の凹凸に合わせ、隙間を介して対向する状態で設置する。
<2> Vertical curved surface In the concrete floor slab 1 of the present invention, the seam, which is an end surface orthogonal to the direction of the central axis of the road, is constituted by a vertical curved surface 2 having a continuous curve.
And when installing actually on the steel beam B as a road bridge, the recessed part of the vertical curved surface 2 of one concrete floor slab 1 is made into the convex part of the vertical curved surface 2 of the other adjacent concrete floor slab 1 Install in a state of facing each other through a gap.
Or the vertical curved surface 2 of one concrete floor slab 1 is installed in the state which opposes the unevenness | corrugation of the vertical curved surface 2 of the joint by the side of an abutment, and opposes through a clearance gap.

<3>FRPで構成
この鉛直曲面2の表面をFRP板で構成する。
実際の床版1の構築に際しては、鉛直曲面2を構成するFRP板を、コンクリート床版1の妻板としての型枠として配置する。
そしてFRP板の裏側に鉄筋を配置し、コンクリートを打設してコンクリート床版1を形成する。
<3> Configuration with FRP The surface of the vertical curved surface 2 is configured with an FRP plate.
In actual construction of the floor slab 1, the FRP plate constituting the vertical curved surface 2 is arranged as a formwork as the end plate of the concrete floor slab 1.
Then, a reinforcing bar is disposed on the back side of the FRP plate, and concrete is placed to form the concrete slab 1.

<4>控え板
FRP板の鉛直曲面2の背面には、複数個所に控え板3を突出する。
この控え板3は床版1のコンクリートの内部に配置されることになる。
各控え板3には貫通孔31を開口して、これらの貫通孔31を貫通させて鉄筋などを配置する。
この貫通させた鉄筋は、道路橋の中心軸を横断する方向に配置することになる。
さらに、FRP板の鉛直曲面2の背面や、控え板3の表面には砂などの粒子を接着剤で塗布すると、コンクリート床版1とコンクリートとの付着を大きくすることもできる。
<4> Retaining plate Retaining plates 3 protrude at a plurality of locations on the back surface of the vertical curved surface 2 of the FRP plate.
The backing plate 3 is disposed inside the concrete of the floor slab 1.
Through holes 31 are opened in the respective retainer plates 3, and reinforcing bars and the like are disposed through the through holes 31.
This penetrated reinforcing bar is arranged in a direction crossing the central axis of the road bridge.
Further, when particles such as sand are applied to the back surface of the vertical curved surface 2 of the FRP plate and the surface of the backing plate 3 with an adhesive, the adhesion between the concrete floor slab 1 and the concrete can be increased.

<5>係合溝
FRP製の鉛直曲面2には、水平方向に係合溝4を連続して形成する。
FRP製の鉛直曲面2が連続した曲面を形成しているから、係合溝4もまた連続した曲線を形成することになる。
この係合溝4の溝底41と縁板は、鉛直曲面2から外側に向けて突出して状態で位置している。
実際の道路橋においてコンクリート床版1を鋼桁Bの上に配置する場合には、一方のコンクリート床版1の鉛直曲面2の係合溝4と、隣接する他方のコンクリート床版1の鉛直曲面2の係合溝4は対向する位置に配置されることになる。
<5> Engagement groove The engagement groove 4 is continuously formed in the horizontal direction on the vertical curved surface 2 made of FRP.
Since the FRP vertical curved surface 2 forms a continuous curved surface, the engagement groove 4 also forms a continuous curve.
The groove bottom 41 and the edge plate of the engagement groove 4 are located in a state protruding from the vertical curved surface 2 toward the outside.
When the concrete floor slab 1 is arranged on the steel beam B in an actual road bridge, the engaging groove 4 of the vertical curved surface 2 of one concrete floor slab 1 and the vertical curved surface of the other adjacent concrete floor slab 1 are provided. The two engaging grooves 4 are arranged at opposing positions.

<6>止水帯
止水帯5は、ゴムなどの柔軟性、耐久性のある材料の薄い膜によって構成した断面V字状の長い部材である。
そしてその断面の両端には、折り返し縁51を形成する。
すなわち断面でみると、中央のV字状の両縁に、逆V字状の折り返し縁51を形成した形状を呈する。
この折り返し縁51の寸法は、前記した係合溝4の内部に、上から挿入できる厚さ、幅を備えている。
そして、実際にコンクリート床版1を鋼桁Bの上に配置した場合に、対向する場所に位置する両側の係合溝4の内部に、断面V字形の止水帯5の折り返し縁51を嵌合する。
この止水帯5の設置は、コンクリート床版1の配置後に行うから、狭い隙間からの作業になる。
しかし本発明の係合溝4は上向きの空間であり、止水帯5の折り返し縁51は下向きの単片であるから、何らかの治具を使用して上から押込めるだけで、両者をパチッと嵌合することができる。
<6> Water stop zone The water stop zone 5 is a long member having a V-shaped cross section constituted by a thin film of a flexible and durable material such as rubber.
Then, folded edges 51 are formed at both ends of the cross section.
That is, when viewed in cross-section, it has a shape in which inverted V-shaped folded edges 51 are formed on both edges of the center V-shape.
The folded edge 51 has a thickness and a width that can be inserted into the engaging groove 4 from above.
And when the concrete floor slab 1 is actually disposed on the steel beam B, the folded edge 51 of the water-stop band 5 having a V-shaped cross section is fitted inside the engaging grooves 4 on both sides located at opposite positions. Match.
Since the waterstop 5 is installed after the concrete slab 1 is arranged, the work is performed from a narrow gap.
However, since the engagement groove 4 of the present invention is an upward space and the folded edge 51 of the waterstop 5 is a downward single piece, both can be snapped by simply pushing in using some jig. Can be fitted.

<7>止水帯の撤去と再設置
図4に示すように、道路橋Iと、道路橋IIのコンクリート床版1の継手部Cには隙間が存在する。
そのために、この隙間から砂や塵埃が挿入し、それらがタイヤで押込められるので止水帯5は破損しやすい。
破損したら撤去して再設置をする必要があるが、その場合に、道路橋の交通の支障になる時間を短くするために、破損した止水帯5の撤去と、再設置の作業は簡単で短時間に完了する作業であることが要求される。
その点で本発明の止水帯5の設置構造は、前記したように係合溝4は上向きの空間であり、止水帯5の折り返し縁51は下向きの単片であるから、何らかの治具を使用して上から引き揚げるだけで容易に止水帯5を係合溝4から引き出すことができる。
再設置の際には、引き出して撤去した後に、何らかの治具を使用して上から押込めるだけで、再度、両者をパチッと嵌合することができる。
<7> Removal and Reinstallation of Water Stop Zone As shown in FIG. 4, there is a gap in the joint portion C of the road deck I and the concrete floor slab 1 of the road bridge II.
Therefore, sand and dust are inserted from this gap and they are pushed in by the tire, so the water stop zone 5 is easily damaged.
If it is damaged, it must be removed and re-installed. In that case, in order to shorten the time that hinders traffic on the road bridge, the removal and re-installation of the damaged water stop 5 is easy. The work must be completed in a short time.
In that respect, the installation structure of the waterstop 5 of the present invention is that, as described above, the engagement groove 4 is an upward space, and the folded edge 51 of the waterstop 5 is a downward single piece. The waterstop 5 can be easily pulled out from the engagement groove 4 simply by lifting the top from above.
At the time of re-installation, after pulling out and removing, it is possible to snap them together again simply by pushing in from above using some kind of jig.

<8>均一な摩耗(図5)
上記したように本願発明の継手では、その端面はFRP製の鉛直曲面2で構成してある。
そのために、従来の鋼材と比較して、タイヤの通過による摩擦に対する抵抗が大きくない。
そのために、図5に示すように、FRP製の端面の鉛直曲面2はコンクリート1の摩耗と同時に摩耗してゆく。
したがって従来の鋼板製の継手構造のように、端面の板だけが地上部分へ突出することがない。
その結果、端面とコンクリートとの一体化が長く維持され、両者間に隙間が生じたり、その隙間に雨水や塩水が浸入することがない。
<8> Uniform wear (Figure 5)
As described above, in the joint of the present invention, the end surface is constituted by the vertical curved surface 2 made of FRP.
Therefore, compared with the conventional steel material, the resistance with respect to the friction by passage of a tire is not large.
Therefore, as shown in FIG. 5, the vertical curved surface 2 of the end surface made of FRP is worn simultaneously with the wear of the concrete 1.
Therefore, unlike the conventional steel plate joint structure, only the end face plate does not protrude into the ground portion.
As a result, the integration between the end face and the concrete is maintained for a long time, and there is no gap between them, and rainwater and salt water do not enter the gap.
