Description
【０００１】 （産業上の利用分野） この考案は冬道において道路の所どころで、マンホール鉄蓋部分の上の雪が融 け、大きな段差ができ、交通安全上支障となっています。 この段差を解消するために考案したマンホール断熱鉄蓋に関するものである。(Industrial field of application) [0001] This device is a road safety problem on winter roads because snow on the iron cover of manholes melts and large steps are created. The present invention relates to a manhole insulating iron lid devised to eliminate this step.
【０００２】 （従来の技術） 従来のマンホール断熱鉄蓋はポリエチレン樹脂製で、マンホール鉄蓋と分離し ていて、マンホール鉄蓋の裏面には補強突起板があるため、空間ができ密着され ず断熱性が劣っていた。 又マンホール鉄蓋と一体化されていないため水が混入し耐水性が劣る欠点や、 破損した場合、補修ができない欠点もあり、設置する場所の気温条件により容易 に断熱材の厚さを変える事もできない欠点もあり実用化するにも問題があった。(Prior Art) A conventional manhole heat insulating iron lid is made of polyethylene resin and is separated from the manhole iron lid, and since there is a reinforcing projection plate on the back of the manhole iron lid, there is a space and heat is not tightly adhered. The sex was inferior. In addition, since it is not integrated with the manhole iron cover, it has the drawback of poor water resistance due to water mixing in, and the inability to repair it if it is damaged. There was a drawback that could not be achieved, and there was a problem in putting it to practical use.
【０００３】 （考案が解決しようとする課題） 本考案は以上の欠点を解決するため瞬間吹き付け発砲ウレタンフォームと厚手 粘着性布テープを使用しマンホール鉄蓋と一体化し、より効果のでる実用的な物 にすることを目的てして考案されたのである。(Problems to be Solved by the Invention) In order to solve the above-mentioned drawbacks, the present invention uses a momentary blowing foaming urethane foam and a thick adhesive cloth tape and integrates them with a manhole iron lid to make it more practical. It was devised with the aim of becoming a product.
【０００４】 （考案を解決するための手段） マンホール鉄蓋（２）の外周に厚手粘着性布テープ（３）を張り、瞬間吹き付 け発砲ウレタンフォーム（１）をマンホール鉄蓋（２）の裏面に吹き付けし硬化 させ接合一体化したもの。(Means for Solving the Invention) A thick adhesive cloth tape (3) is attached to the outer periphery of the manhole iron cover (2), and a momentary blowing foam urethane foam (1) is attached to the manhole iron cover (2). It is sprayed on the back side, cured, and joined and integrated.
【０００５】 （作 用） 道路用積雪時事故防止マンホール断熱蓋はマンホール鉄蓋裏面に、瞬間吹き付 け発砲ウレタンフォームを吹き付けし接合一体化されたもので鉄蓋裏面の補強突 起板にも密着し気密性と断熱効果のある構造となっている。吹き付け発砲ウレタ ンフォームの厚さも厚手粘着性布テープをマンホール鉄蓋外周に使用することに より自在に変えることができ短時間で設置施工ができ断熱効果があるため積雪時 の段差解消となり車両や歩行者の事故防止となるものである。(Working) Preventing accidents during snowfall for roads The manhole insulation cover is integrated with the back of the manhole iron lid by spraying urethane foam with instant spraying on the back of the iron lid. It has a structure that is in close contact with airtightness and has a heat insulating effect. The thickness of the blowing foam urethane foam can be freely changed by using a thick adhesive cloth tape on the outer circumference of the manhole iron lid, and it can be installed in a short time and has a heat insulating effect, which eliminates the step difference in snow and This will prevent accidents for pedestrians.
【０００６】 （実施例） このマンホール断熱鉄蓋は車道にある既設マンホール鉄蓋や歩道にある既設マ ンホール鉄蓋などの裏面に設置施工し使用する。(Example) This manhole insulating iron lid is installed and used on the back surface of an existing manhole iron lid on a roadway or an existing manhole iron lid on a sidewalk.
【０００７】 （考案の効果） 積雪時など車道や歩道に設置されているマンホール鉄蓋は、マンホールの中の 温度が外気温度より高いため、その熱によりマンホール鉄蓋の上面はいつも雪が 融けているため段差があり車両や歩行者の通行に支障をきたし事故の発生がたび たびあった。 又従来の工法だと現場での施行時間がかかり車両や歩行者の通行にも支障があり 、断熱効果もあまりなかった、本考案はこれらを解決するために役立つものであ る。 考案の効果としてはマンホール裏面に瞬間吹き付け発砲ウレタンフォームを吹き 付けすることにより、鉄蓋と一体化され密着度があるため、より断熱効果と耐水 性に優れマンホール鉄蓋の上面は雪が融けなく段差ができなくなり車両や歩行者 の事故防止につながる。 使用する材質は瞬間吹き付け発砲ウレタンフォームなので、６０秒以内で硬化し 、厚手の粘着性布テープを鉄蓋外周に張り付け型枠とするためウレタンフォーム の厚さも自在に変えることができる。 ウレタンフォームが硬化したら、すぐに粘着性布テープを取り外し出来るため短 時間で施工が完了する事が出来る。 又設置施工後破損した場合でも短時間で部分補修ができ非常に経済的である。(Effect of the Invention) Since the temperature inside the manhole of the manhole iron lid installed on the roadway or sidewalk such as during snowfall is higher than the outside air temperature, the heat always melts the snow on the upper surface of the manhole iron lid. As a result, there were steps, which hindered the passage of vehicles and pedestrians, and accidents frequently occurred. In addition, the conventional construction method takes a long time for on-site execution, obstructs the passage of vehicles and pedestrians, and does not have much heat insulation effect. The present invention is useful for solving these problems. The effect of the idea is that by spraying urethane foam on the back of the manhole, it is integrated with the iron lid and has a close contact, so it has better heat insulation and water resistance. This will prevent accidents for vehicles and pedestrians. The material used is urethane foam that is instantly blown, so it cures in less than 60 seconds, and a thick adhesive cloth tape is attached to the outer circumference of the iron lid to form a form, so the thickness of the urethane foam can be freely changed. Once the urethane foam has hardened, the adhesive cloth tape can be removed immediately, so the construction can be completed in a short time. Moreover, even if it is damaged after installation, it can be repaired in a short time, which is very economical.
