Description

本発明は、道路の路肩に並べて設置し、道路に沿って設けるガードレールの支柱を支持するプレキャスト型のガードレール用の基礎ブロックに関するものである。   The present invention relates to a base block for a precast type guardrail that is installed side by side on a shoulder of a road and supports guardrail columns provided along the road.

この種のガードレール用の基礎ブロックは、道路に沿って路肩に配置し、これに設けた支柱用穴に支柱を建て込み固定するようになっており、またこれの結合構造は、隣接するもの双方の側壁を貫通するボルトにて連結するようになっている(例えば、特許文献1参照)。   This type of guardrail base block is placed on the shoulder along the road, and the struts are built in and fixed to the strut holes provided on the base block. It connects with the volt | bolt which penetrates the side wall of this (for example, refer patent document 1).

上記従来のガードレール用の基礎ブロックは、底版と、この底版の前端部に立設すると共に、支柱用穴を有する前壁と、底版の両側で、かつ前壁に対して直角方向に設けられた左右の側壁とからなっている。そしてこの基礎ブロックを道路に沿って路肩に並べた状態で、隣接する基礎ブロックの側壁相互にボルトを水平方向に貫通させ、その両端をナットで固定するようにしている。また、ボルトにて連結される両側壁間の連結用空間内にコンクリートを充填している。   The base block for the conventional guard rail is provided on the bottom plate, the front end portion of the bottom plate, the front wall having a column hole, on both sides of the bottom plate and in a direction perpendicular to the front wall. It consists of left and right side walls. Then, in a state where the foundation blocks are arranged on the shoulder along the road, the bolts are passed through the side walls of the adjacent foundation blocks in the horizontal direction, and both ends thereof are fixed with nuts. Moreover, the concrete is filled in the space for connection between both side walls connected with a volt | bolt.

特開2003−119739号公報Japanese Patent Laid-Open No. 2003-119739

上記従来の基礎ブロックにあっては、これを連結するためのボルトが隣接して対向する2つの側壁を貫通し、その両側に、各側壁の連結用空間の反対側からナットを締め付けて結合するようになっているため、ボルトの側壁間における部分はコンクリートにて覆われるが、ナット部分が底版側に露出されているため、この部分に防錆処理等の対策をとらなければならなかった。   In the above-mentioned conventional basic block, the bolt for connecting it passes through two adjacent side walls facing each other, and a nut is fastened to both sides from the opposite side of the connecting space of each side wall. As a result, the portion between the side walls of the bolt is covered with concrete, but the nut portion is exposed on the bottom plate side, so measures such as rust prevention treatment have to be taken on this portion.

また、ガードレールはカーブ施工を伴うことが多く、その場合に用いられる基礎ブロックも上記カーブに沿う姿勢に設置されるが、このときの隣接対向して連結するための両側壁の平行姿勢が扇状になる。このため、両側壁を貫通するボルトの貫通姿勢に自由度をもたせるために、これの貫通穴を上記ガードレールの施工曲率半径を考慮した形状にしなければならずやっかいであった。想定されるあらゆる曲率に対応させるにはこのボルト穴の径が大きくなってしまい、往々にしてこれが大きすぎて、側壁の強度低下を誘発している。また、ボルトに締結するナットの座部形状もボルトに対する側壁の姿勢に応じて対応するように球面状にしなければならず、高価になってしまう。   Also, guardrails often involve curve construction, and the foundation block used in that case is also installed in a posture along the curve, but the parallel posture of both side walls to connect adjacently facing at this time is a fan shape Become. For this reason, in order to give a freedom degree to the penetrating posture of the bolts penetrating the both side walls, it has been troublesome to make the through hole into a shape in consideration of the radius of curvature of the guard rail. The diameter of the bolt hole is increased to accommodate all possible curvatures and is often too large, causing a reduction in the strength of the sidewall. In addition, the shape of the seat portion of the nut to be fastened to the bolt must be spherical so as to correspond to the posture of the side wall with respect to the bolt, which is expensive.

また従来の基礎ブロックの側壁は前壁に対して直角方向で、かつ直線状になっていたため、連結用空間に充填固化されたコンクリートに対して側壁の1つの側面にて結合されることになり、隣接する基礎ブロックにおいて、一方の基礎ブロックに自動車事故等により、これの底版の後端側が浮き上がる方向に力が加わったときにおいての側壁の抵抗力が今一つ少なかった。   In addition, since the side walls of the conventional foundation block are perpendicular to the front wall and are linear, the side walls of the foundation block are bonded to the concrete filled and solidified in the connecting space. In the adjacent foundation block, the resistance of the side wall when the force was applied in the direction in which the rear end side of the bottom plate was lifted due to an automobile accident or the like on one of the foundation blocks was still less.

本発明は上記した従来の課題を解決するためになされたもので、その構成、すなわちガードレール用の基礎ブロックは、延長方向に連結して用いられるガードレール用の基礎ブロックにおいて、底版と、この底版の前端に立設した前壁と、この前壁の一部を厚くして支柱建て込み用の穴を設けた補強ブロックと、底版の両端より内側の位置に上記前壁に接続して設けられた側壁とを一体成形してなり、側壁を、一端を前壁に接続して前後方向に延設した長辺側壁と、長辺側壁の他端より底版の側端に向けて前壁と平行に連設した短辺側壁とにてL字状に形成し、この側壁と前壁の一部とで囲まれる連結用空間内に、隣接するブロック相互を連結する連結手段を設けた構成になっている。   The present invention has been made in order to solve the above-described conventional problems, and the configuration thereof, that is, the guardrail foundation block, is a guardrail foundation block that is used by being connected in the extending direction. A front wall standing at the front end, a reinforcing block with a part of this front wall thickened and provided with holes for building up the columns, and connected to the front wall at positions inside the both ends of the bottom plate The side wall is integrally formed, and the side wall is connected to the front wall with a long side wall extending in the front-rear direction, and parallel to the front wall from the other end of the long side wall toward the side edge of the bottom plate. It is formed in an L shape with the short side wall provided continuously, and has a configuration in which connecting means for connecting adjacent blocks is provided in a connecting space surrounded by this side wall and a part of the front wall. Yes.

そして上記のガードレール用の基礎ブロックにおいて、連結手段が、連結用空間内の前後方向の複数個所に、ねじ穴部材をインサートして設けた複数のボルト用台座と、隣接するブロック相互のボルト用台座間に、ボルトによる締結間隔を任意にすることができるようにかけわたして両端をボルトにてボルト用台座に固定する連結鉄筋と、連結用空間内に充填されるモルタルあるいはコンクリートからなっており、また、上記ボルト用台座の底面を連結用空間の底面に対して高くし、さらに連結用空間の側面に底面と平行にして連続あるいは断続する溝を設けた構成になっている。   In the base block for the guard rail, the connecting means includes a plurality of bolt bases provided by inserting screw hole members at a plurality of positions in the front-rear direction in the connecting space, and a bolt base between adjacent blocks. It consists of a connecting rebar that fixes both ends to the bolt pedestal with bolts, and a mortar or concrete filled in the connecting space, so that the fastening interval between the bolts can be set arbitrarily. The bottom surface of the bolt base is made higher than the bottom surface of the connection space, and a groove that is continuous or intermittent is provided on the side surface of the connection space in parallel with the bottom surface.

本発明によれば、隣接するブロック相互を連結する連結部の構成を簡素化することができると共に、連結強度を大きくすることができる。   ADVANTAGE OF THE INVENTION According to this invention, while being able to simplify the structure of the connection part which connects adjacent blocks, connection strength can be enlarged.

そして特に請求項1に係る発明では、L字状に形成した側壁と前壁とで囲まれる連結用空間内に上記連結手段を設けたことにより、従来のように側壁にボルトが貫通する穴を設ける必要がなく、プレキャスト成形する際の基礎ブロックの成形を容易に行うことができる。   In particular, in the invention according to claim 1, by providing the connecting means in the connecting space surrounded by the L-shaped side wall and the front wall, a hole through which the bolt penetrates the side wall as in the prior art. There is no need to provide it, and it is possible to easily form the foundation block during precast molding.

また、連結用空間を構成するための側壁をL字状に形成し、前後方向で延設した長辺側壁の他端より短辺側壁を底版の側端に向けて前壁と平行に連設したことにより、長辺側壁と共に、短辺側壁の内側面にて連結用空間内のモルタルやコンクリートの固化結合材をグリップすることができて、モルタルやコンクリートを介しての隣接する基礎ブロックとの連結を強めることができ、前壁の前端を支点として前方向へ転倒する力が基礎ブロックに作用したときに、この短辺側壁のグリップ力が有効に作用して上記の転倒力に対する抵抗力を大きくすることができる。   Further, the side wall for forming the connecting space is formed in an L shape, and the short side wall is connected in parallel with the front wall from the other end of the long side wall extending in the front-rear direction toward the side edge of the bottom plate. As a result, the mortar and concrete solidified binder in the connecting space can be gripped on the inner side surface of the short side wall together with the long side wall, and the adjacent base block via the mortar or concrete can be gripped. When the force that falls forward is applied to the base block with the front end of the front wall as a fulcrum, the gripping force of this short side wall effectively acts to increase the resistance against the above-mentioned fall force. Can be bigger.

また、請求項2に係る発明では、連結手段においての連結鉄筋が連結用空間内に位置して、ここに充填されるモルタルやコンクリート内に埋設されることにより、この連結鉄筋及びこれをボルト用台座に締結するボルトの防錆処理を省くことができる。   Moreover, in the invention which concerns on Claim 2, the connection rebar in a connection means is located in the space for connection, and it is embed | buried in the mortar and concrete with which this connection rebar and this are used for bolts. It is possible to omit the rust prevention treatment of the bolts fastened to the pedestal.

さらに、請求項3に係る発明では、上記ボルト用台座が連結用空間の底面に対して高くなっていることにより、これに締結される連結鉄筋が連結用空間内の底面から浮いた状態で固定され、この連結鉄筋の全体を上記のモルタルやコンクリート内に埋設させることができる。   Furthermore, in the invention which concerns on Claim 3, since the said pedestal for bolts is high with respect to the bottom face of the connection space, it fixes in the state in which the connection reinforcement fastened by this floated from the bottom face in the connection space Then, the entire connecting reinforcing bar can be embedded in the mortar or concrete.

そしてさらに、連結用空間を構成する側壁の側面に溝を設けたことにより、この部分での上記グリップ力を大きくすることができる。   Further, by providing the groove on the side surface of the side wall constituting the connection space, the grip force at this portion can be increased.

The groove 9 may also be provided on the short side walls 5b and 6b. Further, the groove 9 may have an intermittent shape other than the continuous shape.

連結用空間8,8の底面には、前後方向に離隔された2箇所に連結用台座10,10が底面より高くして設けてある。そしてこの連結用台座10の座面にはボルト用穴11が、台座側にインサートされた棒材に形成して設けてある。   On the bottom surfaces of the connecting spaces 8 and 8, connecting pedestals 10 and 10 are provided at two positions separated in the front-rear direction so as to be higher than the bottom surface. Bolt holes 11 are formed on the seating surface of the connecting pedestal 10 so as to be formed on a bar inserted on the pedestal side.

上記構成の基礎ブロック1は、前壁3の側端を隣接させて道路に沿って路肩部に配置される。このとき、図5に示すように、隣接する基礎ブロック1の相互の連結用空間8が対向される。そしてこの連結用空間8,8内で隣接方向に対向するボルト用台座10,10が、それぞれのボルト用ねじ穴11,11にねじ込むボルト12に両端を結合した連結鉄筋13にて連結される。   The foundation block 1 having the above-described configuration is disposed on the shoulder portion along the road with the side ends of the front wall 3 being adjacent to each other. At this time, as shown in FIG. 5, the mutual connection spaces 8 of the adjacent basic blocks 1 are opposed to each other. The bolt bases 10 and 10 facing in the adjacent direction in the connecting spaces 8 and 8 are connected by connecting reinforcing bars 13 having both ends coupled to bolts 12 screwed into the bolt screw holes 11 and 11, respectively.

また、上記連結鉄筋13を結合してからの連結用空間8内にモルタルあるいはコンクリートを充填する。このときのモルタルやコンクリートは連結鉄筋13の下側にも空間が生じることなく充填されると共に、側壁5,6に設けた溝9内にも充填される。   Further, mortar or concrete is filled in the connecting space 8 after the connecting rebar 13 is connected. At this time, the mortar and concrete are filled in the groove 9 provided in the side walls 5 and 6 while filling the lower side of the connecting rebar 13 without generating a space.

上記連結鉄筋13の断面形状は問わないが、一般には図7(a)に示すような板状材を短冊状にしたものを用いる。そしてその一端にはボルト穴13aを、他端に長穴13bを設け、両連結用台座10,10間の間隔の不同に対して対応できるようになっている。また、図7(b)に示すように、細い丸棒を長いリング状に成形したものを用いてもよい。   The cross-sectional shape of the connecting rebar 13 is not limited, but generally, a plate-shaped material as shown in FIG. A bolt hole 13a is provided at one end, and a long hole 13b is provided at the other end so as to be able to cope with the non-uniform spacing between the connecting bases 10 and 10. Moreover, as shown in FIG.7 (b), you may use what shape | molded the thin round bar in the long ring shape.

上記のようにして互いに連結された基礎ブロック1は、隣接するもの相互の連結用空間8,8の連結用台座10,10が、両端部がボルト12により固定される連結鉄筋13にて連結される。また、この連結用空間8,8内に充填されて固化されたモルタルあるいはコンクリートにて連結される。基礎ブロック1はガードレールを構築する全域にわたって連続して敷設する。図9は路肩に埋設した状態を示すもので、基礎ブロック1の底版2の上には道路を構成する路材14を入れる。そして穴7に支柱15を建て込み、この支柱15にガードレール16を固定する。   In the foundation blocks 1 connected to each other as described above, the connection bases 10 and 10 of the adjacent connection spaces 8 and 8 are connected to each other by the connecting reinforcing bars 13 whose both ends are fixed by the bolts 12. The In addition, the connecting spaces 8 and 8 are connected by solidified mortar or concrete. The foundation block 1 is laid continuously over the entire area for constructing the guardrail. FIG. 9 shows a state of being embedded in the shoulder of the road, and a road material 14 constituting the road is put on the bottom plate 2 of the foundation block 1. A pillar 15 is built in the hole 7, and the guard rail 16 is fixed to the pillar 15.

上記のように敷設された基礎ブロック1の相互の連結用空間8,8内にモルタルあるいはコンクリートが充填固化されていて、これが側壁5,6の溝9内に入り込んでいること、及び、側壁5,6がL字状に形成されていて、これの短辺側壁5b,6bが前壁3から遠い位置にあることにより、この部分にて、隣接して配置される基礎ブロック1に底版2の後端側が浮き上がる方向に力が作用したときに生じる、前壁3の先端を支点とするモーメントを支持することができる。また、側壁5,6の壁面に設けた溝9内に入り込んだモルタルやコンクリートにても、上記支持力を得ることができる。   Mortar or concrete is filled and solidified in the mutual connecting spaces 8 and 8 of the foundation block 1 laid as described above, and this has entered the grooves 9 of the side walls 5 and 6, and the side walls 5 , 6 are formed in an L shape, and the short side walls 5b, 6b thereof are located far from the front wall 3, so that in this portion, the base block 1 arranged adjacent to the bottom plate 2 It is possible to support a moment generated when a force is applied in a direction in which the rear end side is lifted, with the front end of the front wall 3 as a fulcrum. Further, the supporting force can be obtained even with mortar or concrete that has entered into the grooves 9 provided on the wall surfaces of the side walls 5 and 6.

従って、自動車の衝突等によりガードレールに大きな力が作用して、支柱を介してガードレールを支持している1つの基礎ブロック1に、これの底版2の後端側が浮き上がる方向に大きな力が作用したときに、この力は側壁5,6で固化したモルタルやコンクリート及び連結鉄筋12を介して隣接する基礎ブロックに分散支持される。   Therefore, when a large force acts on the guard rail due to a collision of the automobile and the like, a large force acts on one base block 1 supporting the guard rail via the support in the direction in which the rear end side of the bottom plate 2 is lifted. In addition, this force is distributed and supported by the adjacent foundation blocks via the mortar and concrete solidified on the side walls 5 and 6 and the connecting reinforcing bars 12.
