Abstract: A main rope of an elevator includes a load support portion made of a composite material of high-strength fiber and resin. A design method for the elevator includes setting a design parameter so that a maximum compressive stress at the load support portion bent along a sheave including a drive sheave and a deflector sheave does not exceed compressive strength, and setting the design parameter so that a sum of a maximum tensile stress at the load support portion bent along the sheave and a mean stress additionally applied to the load support portion when a load required to decelerate a car running in a maximum loading state by gravitational acceleration is applied to the main rope does not exceed tensile strength.

Abstract: A suspension body for an elevator includes a core having a belt-like shape, and a covering layer. The core includes a load bearing layer. The load bearing layer is formed of an impregnation resin and a plurality of high-strength fibers. The covering layer covers at least a part of an outer periphery of the core. The plurality of high-strength fibers include a plurality of kinds of high-strength fibers.

Abstract: Provided is a rope including a load supporting member and a covering member covering an outer periphery of the load supporting member. The load supporting member includes: an impregnation material and reinforcement fiber bodies, which continuously extend in a longitudinal direction of the rope, are embedded in the impregnation material, and are configured to support a load acting in the longitudinal direction. The reinforcement fiber bodies include corrugated reinforcement fiber bodies which have, at least in part, a corrugated shape in a section parallel to the longitudinal direction. The corrugated reinforcement fiber bodies have such a length that a total length thereof given when the corrugated reinforcement fiber bodies are straightened is equal to or larger than 1.1 times a total length of the load supporting member.

The core includes a load bearing layer. The load bearing layer is formed of an impregnation resin and a plurality of high-strength fibers. Further, the load bearing layer is divided into a plurality of segment layers arranged apart from each other in a thickness direction of the core. An intermediate layer made of a material different from that for the load bearing layer is interposed between the segment layers adjacent to each other in the thickness direction of the core.

Abstract: A waterproof sheet fixing member for fixing a waterproof thermoplastic resin sheet on a structure to be waterproofed, includes a plate-like main member made of thermoplastic resin, and a conductive multi-aperture sheet having an upper surface and a lower surface. The conductive multi-aperture sheet has a plurality of joining apertures each communicating the upper surface with the lower surface, and is integrally provided in the main member. A method of fixing the waterproof thermoplastic resin sheet includes the steps of fixing the fixing member on a surface of the structure, spreading the waterproof thermoplastic resin sheet on the surface of the structure, and induction heating the conductive multi-aperture sheet via the waterproof thermoplastic resin sheet to melt a portion where the main member contacts the waterproof thermoplastic resin sheet. Thus, the main member is integrally welded to the waterproof thermoplastic resin sheet.
