本発明は、かごせり上は式エレベータのロープ引止め装
置に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a rope retaining device for a car elevator.
従来、ロープ引止め装置は第３図、π４図、第５図のよ
うに溝形鋼の梁１３の７ランジ部分に座板１４を設け、
ロープ留め金具１２を溝内に取付ける構造としていた。Conventionally, a rope restraining device has a seat plate 14 provided at the 7-lung portion of a channel steel beam 13, as shown in Figs. 3, π4, and 5.
The structure was such that the rope fastener 12 was attached within the groove.
ｊ、かじ、この構造には次の欠点があった。This structure had the following drawbacks.
（１）＠重荷重点Ｐは第５図のように梁１３の形状によ
って定められるせん断中心点Ｃとはａの距離のずれが生
じる。このため、梁にはねじりモーメントが発生する。(1) As shown in FIG. 5, the load point P deviates from the shear center point C determined by the shape of the beam 13 by a distance of a. Therefore, a torsional moment is generated in the beam.
（２）ローブ留め金具１２を溝内に収容するために金具
の長さｔより大きい溝の幅りを必要とし、梁１２は強度
上からみて必要以上の大形材料の採用を余儀なくされ、
材料の無駄使いであった。(2) In order to accommodate the lobe fastener 12 in the groove, the width of the groove is required to be larger than the length t of the metal fitting, and the beam 12 is forced to use a larger material than necessary from the viewpoint of strength;
It was a waste of material.
本発明の目的は、梁のねじれをなくすこと、軽量化によ
る省資源、据付作業性の向上が図れるエレベータロープ
引止め装置を提供することにある。SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator rope retaining device that eliminates twisting of beams, saves resources by reducing weight, and improves installation workability.
理論上、梁のねじれをなくすには梁のもりせん断中心位
置を求め、懸垂荷重点はこのせん断中心位置に近づける
ことが必要となる。溝形鋼のせん断中心は反溝側に求め
ることができる。従って、懸垂荷重点を反溝側に置く構
造とすればよい。Theoretically, in order to eliminate twisting in a beam, it is necessary to find the shear center position of the beam and move the suspension load point close to this shear center position. The shear center of the channel steel can be found on the side opposite to the groove. Therefore, a structure may be adopted in which the suspension load point is placed on the side opposite to the groove.
また、梁が強饗上必要最少限のサイズを選定できるよう
にするためには、ロープ留め金具の取付けに際し、収容
寸法の制約を受けない構造とすることである。In addition, in order to be able to select the minimum necessary size of the beam for strength, the structure should be such that the installation of the rope fasteners is not restricted by the accommodation dimensions.
以下、本発明の実施例を第１図により説明する。 Embodiments of the present invention will be described below with reference to FIG.
ローブ引止め装置の座板１４は梁１３の上部に取付ける
。座板１４の取付は強度を増すには補強板１６を座板と
梁のウェブの間に設ける。The seat plate 14 of the lobe retaining device is attached to the upper part of the beam 13. To increase the strength of mounting the seat plate 14, a reinforcing plate 16 is provided between the seat plate and the web of the beam.
このように、ロープ留め金具の取付位置を梁のせん断中
心位置に近いＳの位置に設ける。In this way, the attachment position of the rope fastener is provided at the position S near the shear center position of the beam.
本実施例によれば、第２図のよう１、梁１３に留め金具
１２の長さｔは梁の溝内に収容しないので、梁寸法Ｈは
制約を受けることなく、強匿上の必要条件を満たせば、
任意の材料を使用することができる。According to this embodiment, as shown in FIG. 2, the length t of the fastener 12 on the beam 13 is not accommodated in the groove of the beam, so the beam dimension H is not subject to any restrictions and meets the requirements for security. If you satisfy
Any material can be used.
本発明によれば梁にねじりモーメントが発生したいこと
よシ梁は強度上安全である。According to the present invention, the beam is safe in terms of strength, even though torsional moments do not occur in the beam.
また、材料の軽量化ができ、省資源と共に、据付時の運
搬、荷上げ作業に労を些せず、作業性が向上する。In addition, the weight of the material can be reduced, and in addition to saving resources, there is no need to worry about transportation and loading during installation, which improves work efficiency.
