연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

초록

A crush resistant seamless roofing system is formed by a layer of adjacent panels having loose joints filled by expanding rising foam adhesive, which is trimmed to remove excess foam adhesive above a top plane of the roofing system. The roofing system thus formed is covered by a fabric layer and a coating.

I claim: 1. A method of producing a seamless roofing system comprising the steps of: providing a plurality of hardened foam roofing panels, applying layer of a rising foam adhesive to a pre-determined surface of a roof to be covered, placing a first hardened foam roofing panel of said plurality of hardened foam roofing panel upon said rising foam adhesive upon said roof to be covered; each said hardened foam roofing panel being formed of polyurethane foam wherein each said hardened foam roofing panel has a density of about 2.5 to 3.16 cubic pounds per foot and said hardened foam roofing panel has a top surface, a bottom surface, and at least one first indented periphery; said top surface having an integral layer of fabric bonded to said hardened foam roofing panel; mating said at least one first indented periphery of said first hardened foam roofing panel to a further hardened foam roofing panel upon said layer of rising foam adhesive applied to said predetermined surface of said roof, said further hardened foam roofing panel having at least one further indented periphery, said at least one further hardened foam roofing panel having a density substantially equal to said density of said first hardened foam roofing panel, said at least one first indented periphery of said first hardened foam roofing panel being larger than said at least one second indented periphery of said second hardened foam roofing panel, thereby preventing a tight fit between said at least one first indented periphery of said first hardened foam roofing panel and said at least one second indented periphery of said second hardened foam roofing panel, fitting said at least one first indented periphery and said at least one second indented periphery loosely together with a gap provided between said first hardened foam roofing panel and said at least one second hardened foam roofing panel, and, allowing said rising foam adhesive to rise within said gap therebetween. 2. A method of producing a seamless roofing system according to claim 1, wherein said at least one first indented periphery and said at least one further indented periphery are tongue and groove, respectively. 3. A method of producing a seamless roofing system according to claim 2, wherein said groove is about 22 mm wide and said tongue is about 19 mm wide. 4. A method of producing a seamless roofing system according to claim 2, wherein said at least one first indented periphery and said at least one further indented periphery together form a respective ship and lap joint, respectively. 5. A method of producing a seamless roofing system according to claim 2, wherein said at least one first indented periphery anti said at least one further indented periphery each have a first and a second groove, respectively; and a tongue slideably mounted within said first and said second grooves. 6. The method of producing a seamless roofing system as in claim 1 wherein said fabric is a non-woven polyester fabric. 7. A method of producing a seamless roofing system comprising the steps of: providing a plurality of hardened foam roofing panels, applying layer of a rising foam adhesive to a pre-determined surface of a roof to be covered, placing a first hardened foam roofing panel of said plurality of hardened foam roofing panel upon said rising foam adhesive upon said roof to be covered; each said hardened foam roofing panel has a top surface, a bottom surface, and at least one indented periphery; said top surface having an integral layer of fabric bonded to said hardened foam roofing panel; mating said at least one first periphery of said first hardened foam roofing panel to a further hardened foam roofing panel upon said layer of rising foam adhesive applied to said predetermined surface of said roof, said further hardened foam roofing panel having at least one further indented periphery, said at least one first indented periphery of said first hardened foam roofing panel being larger than said at least one second indented periphery of said second hardened foam roofing panel, thereby preventing a tight fit between said at least one first indented periphery of said first hardened foam roofing panel and said at least one second indented periphery of said second hardened foam roofing panel; and, fitting said at least one first indented periphery and said at least one second indented periphery loosely together with a gap provided between said first hardened foam roofing panel and said at least one second hardened foam roofing panel, allowing said rising foam adhesive to rise within said gap therebetween. 8. The method of producing a seamless roofing system according to claim 7, wherein said at least one first indented periphery and said at least one further indented periphery are tongue and groove, respectively. 9. The method of producing a seamless roofing system according to claim 8, wherein said groove is about 22 mm wide and said tongue is about 19 mm wide. 10. The method of producing a seamless roofing system according to claim 7, wherein said at least one first indented periphery and said at least one further indented periphery together form a ship and lap joint, respectively. 11. The method of producing a seamless roofing system according to claim 7, wherein said at least one first indented periphery and said at least one further indented periphery each have a first and a second groove, respectively; and a tongue slideably mounted within said first and said second grooves. 12. The method of producing a seamless roofing system as in claim 7 wherein said fabric is a non-woven polyester fabric.
