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.

A multi-directional scaffold transport device, which may be attached to each base of a scaffold's legs, provides increased mobility in relation to movement atop corrugated floor decking with vertical anchor studs used in conventional steel I-beam superstructures. The device comprises an elongated flat plate with angled extensions. The angled extensions may form a trapezoidal shape, or more preferably a triangular shape, and may be curved or have compound curvature to enable deflection of the device to either side of any anchor stud encountered, rather than jamming thereon. The elongated flat plate may have minimal length sufficient to normally receive support from at least two peaks of the corrugated decking. The device may incorporate threaded studs protruding from the elongated flat plate, which may be received by holes in the base of the scaffold, and be removeably fastened thereto using nuts. The device may also incorporate vertical walls for increased stiffness.

1. A multi-directional transport device, adapted for use atop a corrugated decking of a building superstructure, said multi-directional transport device comprising: an elongated flat plate, said elongated flat plate having a first end and a second end, a top surface and a bottom surface, said bottom surface being flat and without any steps, each of said first and second ends of said flat plate having an extension plate protruding therefrom at an acute angle with respect to a plane of said elongated flat plate, said extension plate at said first and second ends each narrowing with increasing distance from respective first and second ends, said device comprising one or more studs fixedly secured to a top surface of said elongated flat plate to protrude upwardly therefrom. 2. The multi-directional transport device according to claim 1, wherein said extension plates at said first and second ends each narrow to form a trapezoidal shape, or narrow to a point to form a triangular shape. 3. The multi-directional transport device according to claim 2, wherein said elongated flat plate further comprises one or more stiffeners, said one or more stiffeners protruding upward from said elongated plate between said first end and said second end. 4. The multi-directional transport device according to claim 3, wherein said one or more stiffeners on said elongated plate comprises a first stiffener and a second stiffener respectively located at a first side and a second side of said elongated plate. 5. The multi-directional transport device according to claim 4, wherein said extension plates at said first and second ends each further comprise one or more stiffeners configured to respectively protrude away from a top surface of said extension plates. 6. The multi-directional transport device according to claim 5, wherein said one or more stiffeners on said extension plates comprises a first stiffener and a second stiffener respectively located at a first side and a second side of said extension plates. 7. A multi-directional transport device, adapted for use atop a corrugated decking of a building superstructure, said multi-directional transport device comprising: an elongated flat portion, said elongated flat portion having a top surface, a bottom surface, a first side, a second side, a first end and a second end, said elongated flat portion comprising: a center section, said top surface and bottom surface for said center section being substantially rectangular with said first and second sides being substantially parallel at a center section of said elongated flat portion, said bottom surface of said center section being flat and without any steps therein; andfirst and second end sections, said center section transitioning into said first and second end sections at opposite ends of said center section, each of said first and second end sections comprising a substantially trapezoidal-shaped top surface and bottom surface, with said first and second sides for each of said first and second end sections thereby configured to be respectively convergent toward said first and second ends;first and second angled extension portions protruding respectively from each of said first and second end sections at said first and second ends of said elongated flat portion, each of said first and second angled extension portions having a top surface, a bottom surface, a first side, a second side, and an elevated end being distal from said respective first and second ends of said elongated flat portion; each said first and second sides of said first and second angular extension portions configured to converge to form a triangular shape, with a tip of said triangular shape positioned at each of said respective elevated ends; andone or more studs fixedly secured to said elongated flat portion, and configured to protrude upward and away from said top surface of said elongated flat portion, a portion of each of said one or more studs having external threads. 8. The multi-directional transport device according to claim 7 further comprising a multi-legged scaffold and a plurality of said transport device, each leg of said multi-legged scaffold comprising a base plate with one or more orifices therein configured to correspondingly receive said one or more studs of a respective said transport device. 9. The multi-directional transport device according to claim 8 further comprising means for releasably securing each said base plate of said multi-legged scaffold to said respective transport device. 10. The multi-directional transport device according to claim 7, wherein each of said first and second sides of said first and second angular extension portions converge to form a sharp edge at each said tip. 11. The multi-directional transport device according to claim 7, wherein said bottom surface of each of said first and second angled extension portions is substantially flat. 12. The multi-directional transport device according to claim 7, wherein said bottom surface of each of said first and second angled extension portions is upwardly curved. 13. The multi-directional transport device according to claim 7, further comprising an upstanding stiffener portion on each of said first and second sides of said center section of elongated flat portion. 14. The multi-directional transport device according to claim 13, further comprising an upstanding stiffener portion on each of said first and second sides of said center section of elongated flat portion and of said triangular shape of said first and second angled extension portions. 15. The multi-directional transport device according to claim 7 wherein said tip of said triangular shape of each of said first and second angled extension portions is radiused. 16. The multi-directional transport device according to claim 7 further comprising a coating material applied to said bottom surface of said elongated flat portion, said coating material adapted to provide a low coefficient of sliding friction.
