MULTISPAN CONTINUOUS BEAM (VERSIONS)

摘要

FIELD: construction.SUBSTANCE: invention proposes two versions of double-cantilever beams made of a rolled channel and of a bent Z-shaped channel. The double-cantilever beam is located between supports so that cantilevers of each beam are arranged behind the supports in the previous and the next spans; with that, cantilevers of adjacent beams form a support section near the support, which is equal as to length to two cantilevers. The invention describes versions of attachment of the cantilever to beams of adjacent spans and a beam to a support.EFFECT: reduction of material consumption.2 cl, 9 dwg
