第1例では、道路Rと歩道Fとの境界に段差を形成して設置される縁石ブロックからなる構造物Bに関するものを示してある。  In the first example, a structure relating to a structure B composed of curb blocks installed with a step formed at the boundary between the road R and the sidewalk F is shown.

まず、第1例の構造物用表面改良材Cの構成について説明する。  First, the structure of the structural surface improvement material C of the first example will be described.

第1例の構造物用表面改良材Cは、図1に示すように、カバー本体1,テーパ面2,溝3,ボルト挿通孔4からなる。  As shown in FIG. 1, the surface improvement material C for a structure of the first example includes a cover main body 1, a tapered surface 2, a groove 3, and a bolt insertion hole 4.

カバー本体1は、合成樹脂材で構造物Bの上面Baと側面Bbとに連続して対面する面積を有するように形成された曲板形に形成されている。材料となる合成樹脂材としては、耐候性,耐衝撃性に優れたものが採用される。カバー本体1の表面11は、構造物Bの上面Ba,側面Bbと相似形の平坦面に形成されている。カバー本体1の背面12は、構造物Bの上面Baから側面Bbに向かう方向に延びた多数本のリブ13が設けられて凹凸面に形成されている。  The cover main body 1 is formed in a curved plate shape that is formed of a synthetic resin material so as to have an area that continuously faces the upper surface Ba and the side surface Bb of the structure B. As the synthetic resin material, a material excellent in weather resistance and impact resistance is employed. The surface 11 of the cover body 1 is formed as a flat surface similar to the upper surface Ba and the side surface Bb of the structure B. The back surface 12 of the cover body 1 is formed in an uneven surface with a plurality of ribs 13 extending in a direction from the upper surface Ba of the structure B toward the side surface Bb.

テーパ面2は、カバー本体1の上縁(構造物Bの上面Baに対面する側の縁)と下縁(構造物Bの側面Bbに対面する側の縁)とに設けられ、カバー本体1の表面11から上縁,下縁に向けて下降する傾斜をもつように形成されている。  The taper surface 2 is provided on the upper edge (the edge on the side facing the upper surface Ba of the structure B) and the lower edge (the edge on the side facing the side surface Bb of the structure B). It is formed to have an inclination that descends from the surface 11 toward the upper edge and the lower edge.

溝3は、前述のカバー本体1の背面12のリブ13の間となる凹部に設けられ雨水の流通を確保するもので、構造物Bの上面Baから側面Bbに向かって連通している。  The groove 3 is provided in a concave portion between the ribs 13 on the back surface 12 of the cover body 1 described above to ensure the circulation of rainwater, and communicates from the upper surface Ba of the structure B toward the side surface Bb.

In addition, handling is easy because no special conditions are required for transportation and storage.

合成樹脂材成形技術を利用する製造方法としては、合成樹脂材系である農業用のビニルハウス等で使用されて廃棄されるポリ塩化ビニルシートを製造材料として有効利用し、農業用のビニルハウス等の廃棄物の処理コストを無用にするとともに、材料に掛かるコストを低減することができる。  As a manufacturing method using synthetic resin material molding technology, polyvinyl chloride sheets used and discarded in agricultural vinyl houses that are synthetic resin materials are effectively used as manufacturing materials, agricultural vinyl houses, etc. This makes it possible to eliminate the waste disposal cost and reduce the cost of the material.

この製造材料については、図2に示すように、高温下(例えば、300℃)で洗浄,乾燥を短時間で確実に実施させ、品質を低コストで良質にする。従って、製品としての縁石ブロックの品質も低コストで良質にすることができる。そして、洗浄,乾燥された製造材料については、電気炉等で加熱して溶融させ、必要に応じて着色(必要に応じて、蓄光性,蛍光性のものを選択することも可能)を施してから、金型に注入して圧縮成形する。製造材料としてポリ塩化ビニルを選択した場合には、特に耐候性等に優れ高度の耐久性能が得られる。  As shown in FIG. 2, the manufacturing material is reliably washed and dried at a high temperature (for example, 300 ° C.) in a short time, thereby improving the quality at a low cost. Therefore, the quality of the curb block as a product can be improved at a low cost. The cleaned and dried production material is heated and melted in an electric furnace or the like, and colored as necessary (a phosphorescent or fluorescent material can be selected as necessary). Then, it is injected into a mold and compression molded. When polyvinyl chloride is selected as the production material, it is particularly excellent in weather resistance and the like, and a high durability performance is obtained.

At this time, if necessary, the mounting bolt 5 is not inserted into the bolt insertion hole 4 of the cover body 1 positioned near the damaged portion Bc of the structure B, and the tube is inserted into the bolt insertion hole 4 of the cover body 1. A repair material S having fluidity such as mortar and solidifying later is filled in the damaged portion Bc of the structure B by inserting T or the like.

続く工程では、図3,図8に示すように、取付ボルト5を構造物Bの破損部分Bcの近くに位置しているカバー本体1のボルト挿通孔4にも挿通させボルト穴H(スリーブ6)に螺合させる。  In the subsequent process, as shown in FIGS. 3 and 8, the mounting bolt 5 is also inserted into the bolt insertion hole 4 of the cover main body 1 located near the damaged portion Bc of the structure B, and the bolt hole H (sleeve 6) is inserted. ).

続く工程では、図3,図9に示すように、カバー本体1のボルト挿通孔4にボルトカバー7を嵌合する。ボルトカバー7は、取付ボルト5の頭部を隠蔽して全体の美観を向上させるとともに取付ボルト5への土砂の付着を防止する。  In the subsequent process, as shown in FIGS. 3 and 9, the bolt cover 7 is fitted into the bolt insertion hole 4 of the cover body 1. The bolt cover 7 conceals the head of the mounting bolt 5 to improve the overall aesthetics and prevent soil and sand from adhering to the mounting bolt 5.

第1例によると、構造物Bをボルト締で取付けられる構造物用表面改良材Cで覆ってしまうため、図7に示すように構造物Bの破損部分Bcに補修材料Sを充填しなくても、モルタル塗補修における構造物Bの面倒な表面仕上げや充填部分の剥離,分離の不具合を解消することができる。従って、補修の作業性,耐久性が高くなる。特に、構造物用表面改良材Cの背面に構造物Bの表面における雨水の流下を許容する溝3が設けられ、構造物B,構造物用表面改良材Cの間に雨水が滞溜するのを防止することができるため、補修の耐久性が極めて高くなる。なお、構造物用表面改良材Cの背面に設けられた溝3は、構造物Bとの間に空隙を形成して車両等の衝突に対する緩衝機能を備えることにもなる。  According to the first example, since the structure B is covered with the surface improvement material C for the structure that can be attached by bolting, the damaged material Bc of the structure B is not filled with the repair material S as shown in FIG. In addition, troublesome surface finishing of the structure B and detachment and separation of the filling portion in the mortar coating repair can be solved. Therefore, the workability and durability of repair are enhanced. In particular, a groove 3 that allows the rainwater to flow down on the surface of the structure B is provided on the back surface of the structure surface improvement material C, and rainwater accumulates between the structure B and the structure surface improvement material C. Therefore, the durability of repair is extremely high. In addition, the groove | channel 3 provided in the back surface of the surface improvement material C for structures will also provide a buffer function with respect to collisions, such as a vehicle, by forming a space | gap between the structures B.

また、構造物用表面改良材Cのボルト挿通孔4を利用して補修材料Sを構造物Bの損傷部分Bcに充填することで、従来一般的に行われてきたモルタル充填による補修を併用することができるため、構造物Bをより確実に補修することができる。特に、既に構造物用表面改良材Cによって覆われた構造物Bの損傷部分Bcに補修材料Sが充填されることから、補修材料Sの充填後に特別に養生期間を確保する必要がなくなるため、工期を長期化させることなく充填による補修を併用することができる。  Further, the repair material S is filled in the damaged portion Bc of the structure B by using the bolt insertion hole 4 of the surface improvement material C for the structure, so that the repair by the mortar filling which has been generally performed conventionally is also used. Therefore, the structure B can be repaired more reliably. In particular, since the repair material S is filled in the damaged portion Bc of the structure B already covered with the surface improvement material C for the structure, it is not necessary to secure a special curing period after filling the repair material S. Repair by filling can be used in combination without extending the construction period.

また、構造物用表面改良材Cのカバー本体1に構造物Bの上面Baと側面Bbとに対面する位置に取付ボルト5が挿通されるボルト挿通孔4がそれぞれ貫通されていることで、カバー本体1を構造物Bに沿って精密に覆うように取付けることができる。従って、構造物用表面改良材Cの構造物Bに対するおさまりが良好になる。  Further, the cover body 1 of the surface improvement material C for a structure has a bolt insertion hole 4 through which a mounting bolt 5 is inserted at a position facing the upper surface Ba and the side surface Bb of the structure B. The main body 1 can be attached so as to cover the structure B precisely. Therefore, the fit of the surface improvement material C for structures to the structure B is improved.

また、構造物用表面改良材Cのカバー本体1の上縁に設けられたテーパ面2が歩道Fの急激な段差を消失するため、歩行者の躓きを防止して歩行の安全性を確保することができる。  Moreover, since the taper surface 2 provided in the upper edge of the cover main body 1 of the surface improvement material C for structures lose | disappears the sudden level | step difference of the sidewalk F, a pedestrian's whip is prevented and the safety | security of walking is ensured. be able to.

また、構造物用表面改良材Cは、構造物Bの補修の外に、着色等によって交通安全対策面からの視認性の向上のために改修にも利用が可能である。  In addition to the repair of the structure B, the surface improvement material C for a structure can be used for refurbishment in order to improve the visibility from a traffic safety countermeasure side by coloring or the like.
