[0011] 図 2は図 1の主ロープ 6の断面図である。主ロープ 6の中心には、芯子縛 21が配置 されている。芯子縛 21は、複数本の鋼製素線が撚り合わされてなる芯子縛本体 22と 、芯子縛本体 22を被覆する榭脂製の芯子縛被覆体 23とを有している。芯子縛本体 22の外周部に位置する鋼製素線の断面は、芯子縛本体 22を外周から圧縮すること により異形ィ匕されている。芯子縛被覆体 23は、例えばポリエチレン榭脂等の硬質榭 脂からなっている。  FIG. 2 is a cross-sectional view of the main rope 6 of FIG. In the center of the main rope 6, a core binding 21 is arranged. The core binding 21 has a core binding main body 22 formed by twisting a plurality of steel strands, and a resin core core covering covering 23 covering the core binding main body 22. The cross section of the steel wire located on the outer peripheral portion of the core restraint body 22 is deformed by compressing the core restraint body 22 from the outer periphery. The core-bound covering body 23 is made of a hard resin such as polyethylene resin.
[0012] 芯子縛 21の外周には、複数本 (ここでは 8本)の内層子縛 24からなる内層子縛集 合体 25が配置されている。内層子縛 24は、芯子縛 21を中心として芯子縛 21の外周 に撚り合わされている。各内層子縛 24は、複数本の鋼製素線が撚り合わされてなる 内層子縛本体 26と、内層子縛本体 26を被覆する榭脂製の内層子縛被覆体 27とを 有している。内層子縛本体 26の外周部に位置する鋼製素線の断面は、内層子縛本 体 26を外周から圧縮することにより異形化されている。 [0013] また、内層子縛本体 26の外周には、接着剤が塗布されており、内層子縛本体 26と 内層子縛被覆体 27とは接着剤を介して互いに接着されている。さら〖こ、内層子縛本 体 26に内層子縛被覆体 27を被覆した後、内層子縛 24には、接着剤の接着性能を より確実に発揮させるための安定ィ匕処理が施されている。安定化処理とは、 50— 15 0°C程度の炉内に数分一数日間放置して加熱することにより接着力の強化を図る処 理である。さらに、各内層子縛 24の径は、芯子縛 21の径よりも小さい。即ち、各内層 子縛本体 26に含まれる鋼製素線の本数は、芯子縛本体 22に含まれる構成素線の 本数よりも少ない。 [0012] On the outer periphery of the core tie 21, an inner layer tie assembly 25 composed of a plurality (eight in this case) of inner layer ties 24 is arranged. The inner layer tie 24 is twisted around the core tie 21 around the core tie 21. Each inner layer tying 24 has an inner layer tying body 26 in which a plurality of steel strands are twisted together, and an inner layer tying sheath 27 made of resin that covers the inner layer tying body 26. . The cross section of the steel wire located at the outer peripheral portion of the inner layer constraining body 26 is deformed by compressing the inner layer constraining main body 26 from the outer periphery. [0013] In addition, an adhesive is applied to the outer periphery of the inner layer tying body 26, and the inner layer tying body 26 and the inner layer tying cover 27 are bonded to each other via an adhesive. Furthermore, after coating the inner layer tying cover 27 on the inner layer tying main body 26, the inner layer tying 24 is subjected to a stable treatment for more reliably exhibiting the adhesive performance of the adhesive. Yes. Stabilization is a process of strengthening the adhesive force by leaving it in a furnace at about 50 to 150 ° C for several minutes and heating for a few days. Furthermore, the diameter of each inner layer tie 24 is smaller than the diameter of the core tie 21. That is, the number of steel strands included in each inner layer binding body 26 is smaller than the number of constituent strands included in the core binding body 22.
[0014] さらにまた、内層子縛 24は、芯子縛本体 22に芯子縛被覆体 23を被覆するとともに 、内層子縛本体 26に内層子縛被覆体 27を被覆した後に芯子縛 21の外周に撚り合 わされている。また、内層子縛被覆体 27は、例えばポリエチレン榭脂等の硬質榭脂 からなつている。  [0014] Furthermore, the inner layer tie 24 covers the core tie main body 22 with the core tie cover 23 and the inner layer tie main body 26 with the inner layer tie cover 27 after It is twisted around the outer periphery. Further, the inner-layer child-bound covering 27 is made of hard resin such as polyethylene resin.
[0015] 内層子縛集合体 25の外周には、榭脂製の内層被覆体 28が被覆されている。内層 被覆体 28の外周には、複数本 (ここでは 20本)の外層子縛 29からなる外層子縛集 合体 30が配置されている。外層子縛 29は、内層被覆体 28の外周に撚り合わされて いる。実施の形態 1では、各外層子縛 29は、複数本の鋼製素線が撚り合わされてな る外層子縛本体のみカゝら構成されている。また、各外層子縛 29の径は、内層子縛 24 の径よりも小さい。即ち、外層子縛 29に含まれる構成素線の本数は、内層子縛本体 26に含まれる構成素線の本数よりも少な!/、。  [0015] On the outer periphery of the inner-layer child-bound assembly 25, an inner-layer covering 28 made of resin is coated. On the outer circumference of the inner layer covering 28, an outer layer binding assembly 30 composed of a plurality (20 in this case) of outer layer bindings 29 is arranged. The outer layer tie 29 is twisted around the outer periphery of the inner layer covering 28. In the first embodiment, each outer layer tie 29 is composed only of an outer layer tie main body in which a plurality of steel strands are twisted together. Further, the diameter of each outer layer tie 29 is smaller than the diameter of the inner layer tie 24. That is, the number of constituent wires contained in the outer layer child restraint 29 is smaller than the number of constituent wires contained in the inner layer child restraint body 26! /.
[0016] 外層子縛集合体 30の外周には、榭脂製の外層被覆体 31が被覆されている。内層 被覆体 28は、外層被覆体 31と同種の材料 (成分や機械的特性が同一又は似ている 材料)からなり、外層被覆体 31と一体ィ匕されている。即ち、内層被覆体 28及び外層 被覆体 31は、耐摩耗性が高ぐ摩擦係数が 0. 2以上の高摩擦榭脂材、例えばポリウ レタン樹脂からなっている。  An outer layer covering 31 made of resin is coated on the outer periphery of the outer layer binding assembly 30. The inner layer covering 28 is made of the same kind of material as the outer layer covering 31 (a material having the same or similar components and mechanical properties), and is integrated with the outer layer covering 31. That is, the inner layer covering 28 and the outer layer covering 31 are made of a high-friction resin material having high wear resistance and a friction coefficient of 0.2 or more, for example, a polyurethane resin.
[0017] 外層子縛 29の外周には、接着剤が塗布されており、外層子縛 29と内層被覆体 28 及び外層被覆体 31とは接着剤を介して互いに接着されている。また、内層子縛 24 の外周に接着剤を塗布し、内層子縛 24と内層被覆体 28とを接着剤を介して互いに 接着してもよい。外層子縛 29についても、内層子縛 24と同様に、接着剤の塗布後に 安定化処理が施されて!/、る。 [0017] An adhesive is applied to the outer periphery of the outer layer restraint 29, and the outer layer restraint 29, the inner layer covering 28, and the outer layer covering 31 are bonded to each other via an adhesive. Alternatively, an adhesive may be applied to the outer periphery of the inner layer strap 24 and the inner layer strap 24 and the inner layer covering 28 may be bonded to each other via an adhesive. For the outer layer tie 29, as with the inner layer tie 24, after applying the adhesive Stabilization is applied! /
[0018] 内層及び外層被覆体 28, 31にポリウレタン榭脂を用いる場合、被覆体 28, 31と子 縛 24, 29との接着に使用される接着剤としては、例えばエポキシ系接着剤、フエノー ル系接着剤又はウレタン系接着剤が好適である。  [0018] When polyurethane resin is used for the inner layer and outer layer coverings 28, 31, the adhesive used for bonding the coverings 28, 31 and the straps 24, 29 includes, for example, epoxy adhesives and phenols. A system adhesive or a urethane-based adhesive is preferred.
[0019] このようなエレベータ用ロープでは、芯子縛 21に芯子縛被覆体 23が設けられ、内 層子縛 24に内層子縛被覆体 27が設けられ、外層子縛集合体 30が外層被覆体 31 により被覆されているので、層間や子縛間に安定した榭脂厚を確保することができる とともに、子縛同士の接触をより確実に防止し、長寿命化を図ることができる。  [0019] In such an elevator rope, the core restraint 21 is provided with the core restraint covering 23, the inner layer restraint 24 is provided with the inner layer restraint covering 27, and the outer layer restraint assembly 30 is the outer layer. Since it is covered with the covering 31, it is possible to secure a stable resin thickness between the layers and between the ties, and more reliably prevent contact between the ties, thereby extending the life.
[0020] また、内層子縛本体 26と内層子縛被覆体 27とは接着剤を介して接着されており、 かつ外層子縛 29と外層被覆体 31とは接着剤を介して接着されているので、これによ つても層間や子縛間に安定した榭脂厚を確保することができ、長寿命化を図ることが できる。即ち、主ロープ 6が繰り返し曲げ伸ばしされても、被覆体 27, 28, 31がずれ ることがなく、安定した断面形状が維持される。  [0020] Further, the inner-layer tie-down body 26 and the inner-layer tie-down cover 27 are bonded via an adhesive, and the outer-layer tie 29 and the outer-layer cover 31 are bonded via an adhesive. Therefore, this can also ensure a stable resin thickness between the layers and between the ties, and can extend the service life. That is, even when the main rope 6 is repeatedly bent and stretched, the coverings 27, 28, 31 are not displaced, and a stable cross-sectional shape is maintained.
[0021] さらに、形状が崩れ難い子縛構造を有するとともに硬質樹脂で被覆されている芯子 縛 21が断面の中心に配置されているので、全体としての形状も崩れ難くなり、これに よっても層間や子縛間に安定した榭脂厚を確保することができ、長寿命化を図ること ができる。  [0021] Furthermore, since the core restraint 21 having a restraint structure that does not easily collapse in shape and coated with a hard resin is disposed at the center of the cross section, the overall shape is not easily collapsed. A stable resin thickness can be ensured between the layers and the ties, and the life can be extended.
[0022] ここで、内層子縛 24は、芯子縛本体 22に芯子縛被覆体 23を被覆 (第 1の工程)す るとともに、内層子縛本体 26に内層子縛被覆体 27を被覆 (第 1の工程)した後に、芯 子縛 21の外周に撚り合わされ (第 2の工程)、さらに最外層に外層被覆体 31が被覆( 第 3の工程)される。即ち、内層子縛 24は、子縛 21, 24毎に被覆体 23, 27を施工し た後に芯子縛 21に撚り合わせられる。これにより、芯子縛 21と内層子縛 24との間、 及び互いに隣接する内層子縛 24間に安定した榭脂厚を確保することができる。  [0022] Here, the inner layer tie 24 covers the core tie main body 22 with the core tie cover 23 (first step) and the inner layer tie main body 26 with the inner layer tie cover 27. After the (first step), the outer periphery of the core strap 21 is twisted (second step), and the outer layer covering 31 is further coated on the outermost layer (third step). That is, the inner layer tie 24 is twisted to the core tie 21 after the coverings 23 and 27 are applied to the tie 21 and 24 respectively. As a result, a stable resin thickness can be secured between the core tie 21 and the inner layer tie 24 and between the inner layer tie 24 adjacent to each other.
[0023] また、内層子縛被覆体 27の厚さ誤差や、内層子縛 24を撚り合わせる際の押し付け 力誤差により、内層子縛集合体 25の外周に多少の凹凸が生じることがあるが、内層 子縛集合体 25の外周に内層被覆体 28が被覆されているので、芯ロープの断面形状 を安定した形状(円形)とすることができる。これにより、ロープ全体の断面形状も安定 させることがでさる。 [0024] さらに、内層被覆体 28を被覆する際の熱により内層被覆体 28と内層子縛被覆体 2 7とが溶着されるので、ロープ全体の断面形状をより安定ィ匕することができる。 [0023] Further, due to the thickness error of the inner layer tie-down covering 27 and the pressing force error when twisting the inner layer tie-down 24, some unevenness may occur on the outer periphery of the inner layer tie-down assembly 25, Since the inner layer covering 28 is coated on the outer periphery of the inner layer constraining assembly 25, the cross-sectional shape of the core rope can be made stable (circular). As a result, the cross-sectional shape of the entire rope can be stabilized. [0024] Furthermore, since the inner layer covering 28 and the inner layer constraining covering 27 are welded by heat when covering the inner layer covering 28, the cross-sectional shape of the entire rope can be made more stable.
さらにまた、内層被覆体 28は、外層被覆体 31と同種の材料からなり、外層被覆体 3 1と一体化されているので、断面形状をより安定ィ匕し、ロープ全体の長寿命化を図る ことができる。また、外層と内層とが一体化され、外力に対する荷重負担や幾何学的 な変形'変位を、全断面で負担することができる。  Furthermore, the inner layer covering 28 is made of the same material as the outer layer covering 31, and is integrated with the outer layer covering 31, so that the cross-sectional shape is further stabilized and the life of the entire rope is extended. be able to. In addition, the outer layer and the inner layer are integrated, and the load burden on the external force and the geometric deformation and displacement can be borne in the entire cross section.

In the second embodiment, each outer layer tie 32 includes an outer layer tie main body 34 formed by twisting a plurality of steel strands, and an outer layer tie cover made of resin that covers the outer layer tie tie main body 34. 35 and have.
[0026] 図 4は図 3の外層子縛 32の拡大断面図である。外層子縛本体 34と外層子縛被覆 体 35との間、及び外層子縛本体 34を構成する鋼製素線間は、接着剤 36により接着 されている。また、図 5に示すように、各外層子縛 32の外周、即ち外層子縛被覆体 3 5の外周には、外層子縛 32の撚り合わせ前に接着剤 36が塗布される。さら〖こ、これら の接着剤 36には、安定化処理が施される。他の構成は、実施の形態 1と同様である  FIG. 4 is an enlarged cross-sectional view of the outer layer restraint 32 of FIG. The outer layer child restraint body 34 and the outer layer child restraint covering body 35 and the steel wires constituting the outer layer child restraint body 34 are bonded by an adhesive 36. Also, as shown in FIG. 5, an adhesive 36 is applied to the outer periphery of each outer layer tie 32, that is, the outer periphery of the outer layer tie cover 35 before the outer layer tie 32 is twisted. Sarakuko, these adhesives 36 are subjected to stabilization treatment. Other configurations are the same as those in the first embodiment.
[0027] このようなエレベータ用ロープでは、全ての子縛 21, 24, 32の外周に被覆体 23, 2 7, 35が設けられているので、層間や子縛間に安定した榭脂厚を確保することができ 、長寿命化を図ることができる。 [0027] In such an elevator rope, the coverings 23, 2 7, 35 are provided on the outer periphery of all the restraints 21, 24, 32. It can be ensured and the life can be extended.
また、外層被覆体 31を被覆する際の熱により外層被覆体 31と外層子縛被覆体 35 とが溶着されるので、ロープ全体の断面形状をより安定ィ匕することができる。  In addition, since the outer layer covering 31 and the outer layer constraining covering 35 are welded by heat when covering the outer layer covering 31, the cross-sectional shape of the entire rope can be further stabilized.
さらに、各外層子縛 32の外周にも接着剤 36が塗布されているので、外層子縛 32と 被覆体 28, 31とをより確実に一体ィ匕することができる。  Furthermore, since the adhesive 36 is also applied to the outer periphery of each outer layer tie 32, the outer layer tie 32 and the coverings 28 and 31 can be joined together more reliably.
[0028] また、実施の形態 1、 2では、内層子縛 24及び外層子縛 29, 32の撚り合わせ方向 について特に述べていないが、内層子縛 24と外層子縛 29, 32とを互いに逆向きに 撚ることにより、内部の回転トルクをバランスさせることができ、ロープ全体の撚り戻しト ノレクを低減することがでさる。 [0028] In Embodiments 1 and 2, the twisting directions of the inner layer straps 24 and the outer layer straps 29 and 32 are not particularly described. However, the inner layer straps 24 and the outer layer straps 29 and 32 are opposite to each other. In the direction Twisting can balance the internal rotational torque and reduce the untwisting torque of the entire rope.

次に、図 6はこの発明の実施の形態 3によるエレベータ用ロープの断面図である。こ の例では、隣接する内層子縛 24間に極薄い榭脂膜が介在されている力、又は隣接 する内層子縛 24が互いに直接接触している。また、隣接する外層子縛 32間に極薄 Vヽ榭脂膜が介在されて ヽるか、又は隣接する外層子縛 32が互 、に直接接触して ヽ る。内層子縛被覆体 27及び外層子縛被覆体 35の断面形状は、隣接する被覆体 27 , 35との接触面積を十分に確保するため、四隅が丸められた略台形状になっている 。このような断面構造は、例えば、内層子縛 24及び外層子縛 32を撚り合わせる際に 、熱や圧力を加えることにより実現することができる。他の構成は、実施の形態 2と同 様である。  Next, FIG. 6 is a cross-sectional view of an elevator rope according to Embodiment 3 of the present invention. In this example, a force in which an extremely thin resin film is interposed between adjacent inner layer restraints 24, or adjacent inner layer restraints 24 are in direct contact with each other. Further, an ultra-thin V-resin film is interposed between adjacent outer layer bindings 32, or adjacent outer layer bindings 32 are in direct contact with each other. The cross-sectional shapes of the inner layer constraining covering 27 and the outer layer constraining covering 35 are substantially trapezoidal with rounded four corners in order to ensure a sufficient contact area with the adjacent coverings 27 and 35. Such a cross-sectional structure can be realized, for example, by applying heat or pressure when the inner layer strap 24 and the outer layer strap 32 are twisted together. Other configurations are the same as those in the second embodiment.
