Description

この発明は、路面の舗装層に埋設した配管に加温された熱媒体を流すことによって路面を加温して当該路面の融雪ないし凍結防止を行い、更に、当該配管に流した水に太陽熱で加熱された路面の熱を伝達して給湯を行うことを可能にする技術に関するものである。   The present invention warms the road surface by flowing a heated heat medium through a pipe embedded in the pavement layer of the road surface to prevent snow melting or freezing of the road surface, and further, the solar water is applied to the water flowing through the pipe. The present invention relates to a technology that makes it possible to supply hot water by transmitting heat of a heated road surface.

コンクリートやアスファルトで舗装された路面の当該コンクリートやアスファルトの層内に金属管や樹脂管を埋設し、地上の温度が低くなって路面に積雪や凍結のおそれが生じたときに、埋設した金属管や樹脂管に温水その他の熱媒体を流すことにより、舗装面を内部から加温し、その熱で路面の融雪や凍結防止を行う技術は公知である。   When a metal pipe or resin pipe is buried in the concrete or asphalt layer of the road surface paved with concrete or asphalt, and the temperature on the ground becomes low, there is a risk of snow accumulation or freezing on the road surface. A technique for heating a pavement surface from the inside by flowing hot water or other heat medium through the resin pipe and preventing the snow melting and freezing of the road surface with the heat is known.

この従来の融雪路面構造は、平らな基礎面を形成して、その上に金属管や樹脂管からなる熱媒体管をジグザグ状に配置し、これを埋め込むように下地コンクリート層を施工し、その上に表面舗装を施すというものである。路面に積雪や凍結のおそれがあるときは、ボイラなどで加温した水その他の熱媒体を熱媒体管に流して路面を内部から暖め、その熱で路面の融雪や凍結防止を行う。

上記のような従来の融雪路面構造は、基盤上に熱媒体管を配置するときの管の位置決めや固定が面倒で時間がかかること、熱媒体管を埋設した下地コンクリート層が硬化した後でなければ路面の転圧仕上げを行うことができないことなどのために、施工が面倒で時間がかかるという問題があった。また、地盤の不等沈下や不等***によって熱媒体管が損傷したとき、これを部分的に補修することが非常に困難であるという問題があった。   The conventional snow melting road surface structure as described above must be troublesome and time-consuming to position and fix the pipe when placing the heat medium pipe on the base, and after the ground concrete layer in which the heat medium pipe is embedded has hardened. In other words, there is a problem that the construction is troublesome and takes time because the rolling of the road surface cannot be performed. In addition, when the heat medium pipe is damaged due to uneven settlement of the ground or uneven elevation, there is a problem that it is very difficult to partially repair it.

この発明は、上記の問題を解決するためになされたもので、熱媒体管の設置が容易であると共に施工時間も短縮でき、また熱媒体管が損傷したときの路面の部分的な補修も容易に可能な融雪路面構造を得ることを課題としている。   The present invention has been made to solve the above-described problems, and it is easy to install the heat medium pipe, shorten the construction time, and easily repair the road surface when the heat medium pipe is damaged. The objective is to obtain a snowmelt road surface structure that is possible.

この発明は、基盤上に敷設することによって路面を舗装する舗装ブロックを基礎ブロック1(1a、1b)とその上に覆着される上蓋ブロック2(2a、2b)とに二分し、基礎ブロック1には路面下に配置される熱媒体管の位置を規定する管受部6を設けておき、この管受部に嵌め込んだ状態で配設した熱媒体管4を基礎ブロック1上に覆着される上蓋ブロック2によって上から押えて固定する構造の融雪路面構築用の舗装ブロックを提供するものである。   The present invention divides a paving block paving a road surface by laying on a base into a base block 1 (1a, 1b) and an upper cover block 2 (2a, 2b) covered thereon, and the base block 1 Is provided with a tube receiving portion 6 for defining the position of the heat medium tube disposed below the road surface, and the heat medium tube 4 disposed in a state of being fitted in the tube receiving portion is covered on the base block 1.

上蓋ブロック2には、熱媒体管4の間の伝熱を促進する構造を備えさせる。また、基礎ブロック1側には、断熱性を高める構造を付与する。これにより、熱媒体管4を流れる熱媒体の熱が効率よく路面に伝達され、太陽光による路面の熱が効率よく熱媒体管を流れる熱媒体に伝えられる。   The upper lid block 2 is provided with a structure that promotes heat transfer between the heat medium tubes 4. Moreover, the structure which improves heat insulation is provided to the foundation block 1 side. Thereby, the heat of the heat medium flowing through the heat medium pipe 4 is efficiently transmitted to the road surface, and the heat of the road surface by sunlight is efficiently transmitted to the heat medium flowing through the heat medium pipe.

基礎ブロック1に断熱性を付与する構造としては、例えば、ブロックのコンクリートに微細気泡や断熱材を混入し、あるいは熱媒体管4との間に断熱材層26を設ける。また、基礎ブロック1の底面に断熱材層や浅い凹所27を設けることにより、基盤と基礎ブロック1との間の断熱性を高めることができる。上蓋ブロック2の伝熱性を高める構造としては、例えば、金属粉などの熱良導体を混入したコンクリートで上蓋ブロック2を成型する構造、熱媒体管4を押える凹溝10の周面に瀝青、タールなどの可塑性を備えた伝熱材層30を設ける構造が採用できる。更に、熱媒体管4を押える凹溝10の溝面に露出する円弧屈曲部11を設けた熱良導体の伝熱板3を埋設成型することにより、熱媒体管4と路面との間の効率の良い伝熱を図ることができる。   As a structure for imparting heat insulation to the basic block 1, for example, fine bubbles or heat insulating material is mixed in the concrete of the block, or the heat insulating material layer 26 is provided between the heat medium pipe 4. Further, by providing the heat insulating material layer and the shallow recess 27 on the bottom surface of the foundation block 1, the heat insulation between the foundation and the foundation block 1 can be enhanced. As a structure for enhancing the heat transfer property of the upper cover block 2, for example, a structure in which the upper cover block 2 is molded with concrete mixed with a good heat conductor such as metal powder, a bitumen, tar or the like on the peripheral surface of the concave groove 10 for holding the heat medium pipe 4 The structure which provides the heat-transfer material layer 30 provided with the plasticity of this can be employ | adopted.

FIG.

この発明の融雪路面構造は、平面に仕上た基盤面上に基礎ブロック1を敷き並べ、それによって形成される複数の管受部6に熱媒体管4を嵌め込んで配置し、その上に上蓋ブロック2を覆着して目地7をモルタル等で埋めることによって施工される。熱媒体管4として可撓性のある樹脂管を用いることにより、敷設された基礎ブロック1上への熱媒体管4の配置及び位置決めを極めて迅速かつ容易に行うことができる。   In the snow melting road surface structure of the present invention, the foundation block 1 is laid out on a base surface finished in a plane, the heat medium pipes 4 are fitted and arranged in a plurality of pipe receiving portions 6 formed thereby, and an upper cover is formed thereon. It is constructed by covering the block 2 and filling the joint 7 with mortar or the like. By using a flexible resin tube as the heat medium tube 4, the heat medium tube 4 can be arranged and positioned on the laid foundation block 1 very quickly and easily.

基礎ブロック1上に配置された熱媒体管4は、その外周上面を上蓋ブロック2の凹溝10の周面に面接触した状態で固定される。凹溝10の周面に可塑性の伝熱材層30を設けることにより、上蓋ブロック2と熱媒体管4との良好な密着性が得られる。また、上蓋ブロック2に埋設した伝熱部材3の露出部分11によって上から押接されて固定される。熱媒体管4の外周上面と伝熱部材3とが直接接触しているため、熱媒体管4に流した媒体の熱が伝熱部材3に伝えられて上蓋ブロック2に平面的に拡散される。   The heat medium pipe 4 disposed on the base block 1 is fixed in a state in which the outer peripheral upper surface thereof is in surface contact with the peripheral surface of the concave groove 10 of the upper lid block 2. By providing the plastic heat transfer material layer 30 on the peripheral surface of the concave groove 10, good adhesion between the upper lid block 2 and the heat medium pipe 4 can be obtained. In addition, the exposed portion 11 of the heat transfer member 3 embedded in the upper lid block 2 is pressed and fixed from above. Since the outer peripheral upper surface of the heat transfer medium tube 4 and the heat transfer member 3 are in direct contact, the heat of the medium that has flowed through the heat transfer medium tube 4 is transferred to the heat transfer member 3 and diffused planarly to the upper lid block 2. .

この発明の融雪路面構築用の舗装ブロックを用いた路面構造によれば、寒冷地には熱媒体管4に加温媒体を流すことによって路面を加温して、積雪や凍結を防止することができ、一方、夏季においては、太陽熱で加熱された路面の熱を熱媒体管4を流れる水、その他の熱媒体に吸収させて給湯などの熱源として利用できると共に、路面の温度上昇が抑えられてヒートアイランド現象を抑制することができる。   According to the road surface structure using the pavement block for snow melting road surface construction of the present invention, the road surface is warmed by flowing a heating medium through the heat medium pipe 4 in a cold region to prevent snow accumulation and freezing. On the other hand, in the summer, the heat of the road surface heated by solar heat can be absorbed by water flowing through the heat medium pipe 4 or other heat medium and used as a heat source such as hot water supply, and the temperature rise of the road surface is suppressed. The heat island phenomenon can be suppressed.

この発明の融雪路面構造は、基盤上に敷き並べた基礎ブロック1の管受部6に熱媒体管4を嵌め込むことによって熱媒体管4の位置決めが行われるので、熱媒体管4の設置作業が極めて迅速かつ容易に行うことができると共に、熱媒体管4の設置後、すぐに上蓋ブロック2の敷設を行うことができ、従来のように熱媒体管を埋設したコンクリート層の硬化を待つ必要がないので、施工時間も大幅に短縮できる。   In the snow melting road surface structure according to the present invention, the heat medium pipe 4 is positioned by fitting the heat medium pipe 4 into the pipe receiving portion 6 of the foundation block 1 arranged on the base. Can be performed very quickly and easily, and the upper cover block 2 can be laid immediately after the heat medium pipe 4 is installed, and it is necessary to wait for the hardening of the concrete layer in which the heat medium pipe is embedded as in the prior art. Because there is no, the construction time can be greatly reduced.

また、熱媒体管4が損傷したときに、路面の一部の上蓋ブロック2を除去し、更に必要があれば一部の基礎ブロック1を除去して、基盤面を補修して要すれば新たな基礎ブロック1敷設し、切断除去した熱媒体管4を繋ぎ直して新しい上蓋ブロック2を敷設するという作業で、部分的な路面の補修を行うことができるという効果がある。   Further, when the heat medium pipe 4 is damaged, a part of the upper cover block 2 on the road surface is removed, and if necessary, a part of the foundation block 1 is removed, and if necessary, the foundation surface is repaired. The work of laying the basic block 1 and reconnecting the cut and removed heat medium pipe 4 and laying the new upper cover block 2 has the effect of partially repairing the road surface.

また、上蓋ブロック2に設けた凹溝10に可塑性の伝熱材層30を設けることにより、上蓋ブロック2と熱媒体管4とが密着して両者の間の良好な伝熱が得られる。また、上蓋ブロック2内に埋設した熱良導体からなる伝熱部材3で熱媒体管4の上面を押圧して固定する構造を採用することにより、路面と熱媒体管4を流れる熱媒体との間の伝熱効率を向上させて、熱効率の向上を図ることができる。   Further, by providing the plastic heat transfer material layer 30 in the concave groove 10 provided in the upper cover block 2, the upper cover block 2 and the heat medium pipe 4 are brought into close contact with each other, and good heat transfer between them can be obtained. Further, by adopting a structure in which the upper surface of the heat medium pipe 4 is pressed and fixed by the heat transfer member 3 made of a good heat conductor embedded in the upper cover block 2, the road surface and the heat medium flowing through the heat medium pipe 4 are arranged. The heat transfer efficiency can be improved to improve the heat efficiency.
