Abstract
Description
この発明は、集合住宅、スタジアム、その他の建物の手すりや公園等の公共施設の手すり柵に関するもので、特に、風切り音を小さく乃至は消音する構造を有する手すり柵に関するものある。 The present invention relates to a handrail for public housing such as a housing for a housing complex, a stadium, other buildings, and a park, and more particularly to a handrail for a structure that can reduce or mute wind noise.
従来、図２４及び図２５に示すように、間隔を空けて設けた２本の支柱５１の上下に桟５２を夫々設け、これらの当該上下の桟５２の間に、上下の桟５２に沿って等間隔で多数の細板状の手すり子５３を縦方向に設けた手すり柵が設けられている。そして、この細板状の手すり子５３の断面形状は強度や経費の面から矩形である場合が多い。前記細板状の手すり子５３は前記桟５２の長手方向に対して直交して配設されている。 Conventionally, as shown in FIG. 24 and FIG. 25, crosspieces 52 are provided above and below two support posts 51 provided at intervals, and between the upper and lower crosspieces 52, along the upper and lower crosspieces 52. A handrail fence provided with a large number of thin plate-like handrails 53 at equal intervals in the vertical direction is provided. In many cases, the cross-sectional shape of the thin plate-shaped balustrade 53 is rectangular in terms of strength and cost. The thin plate-shaped handrail 53 is disposed orthogonal to the longitudinal direction of the crosspiece 52.
この様な手すり柵は、上記等間隔に多数並べられた、細幅板から成る手すり子先端に風が吹き付けると高い音が発生して騒音となり、近隣の住民の苦情となるおそれがある。この騒音の原因は、断面矩形の細幅の板状の手すり子を多数並べた場合、手すり子の先端に風が吹き付けたときに、各手すり子の端面に音源となる小さな渦が発生してへばりつくことで音が発生し、その音が各手すり子間の空間で共鳴し、周波数の高い音が強く発生する。 When such a handrail fence is blown at the tip of a handrail made of narrow plates arranged at regular intervals, a high noise is generated and there is a risk of complaining to neighboring residents. The cause of this noise is that when a large number of thin plate-shaped handrails with a rectangular cross section are arranged, a small vortex that becomes a sound source is generated on the end face of each handrail when wind blows on the end of the handrail. A sound is generated by sticking, and the sound resonates in the space between the handrails, and a high-frequency sound is generated strongly.
また他に、風が吹き付けたときに、各手すり子の下流に周期的に放出される「カルマン渦」に伴う圧力変動が原因となり、周波数の低い音が発生したり、または、手すり子の振動と手すり子の取付け部で擦れる音が発生することがある。 In addition, when wind blows, pressure fluctuations accompanying the “Karman vortex” periodically released downstream of each balustrade cause a low frequency sound or vibration of the balustrade. A rubbing sound may be generated at the handrail attachment part.
そこで、特許文献１及び２のように、手すり子柵に風が吹き付けると、手すり子毎に同周期の空気の乱れが発生し、手すり子は空気の流れと垂直方向に力を受けて振動するが、多数の手すり子同士を連結する棒状、板状の接続部材又は防振用連結部材を手すり子間に設け、上記振動を抑制するものが開発されている。 Therefore, as in Patent Documents 1 and 2, when wind blows on the balustrade fence, turbulence of air with the same period occurs for each baluster, and the balustrade vibrates by receiving a force in a direction perpendicular to the air flow. However, a rod-like or plate-like connecting member or a vibration isolating connecting member for connecting a large number of handrails between the handrails to suppress the vibration has been developed.
しかしながら、特許文献１及び特許文献２のものは、手すり子の振動による低周波の音の発生は抑制されたが、断面が矩形の各手すり子の端面に風を受けた場合に音源となる小さな渦が発生し、その音が各手すり子間の空間で共鳴し、周波数の高い音が強く発生する点は解消されていない。さらに、これらの特許文献１及び２では、工場又は現場で、手すりを作成した後、多数の手すり子に前記接続部材又は防振用連結部材を取り付けるため、手間のかかる作業が必要となる。 However, in Patent Document 1 and Patent Document 2, generation of low-frequency sound due to handrail vibration is suppressed, but a small sound source becomes a sound source when wind is received at the end face of each handrail whose section is rectangular. The point that a vortex is generated, the sound resonates in the space between the handrails, and a high-frequency sound is generated strongly has not been solved. Furthermore, in these patent documents 1 and 2, since a handrail is created in a factory or on-site, the connecting member or the vibration-isolating connecting member is attached to a large number of handrails, which requires laborious work.
そこで、この発明はこの様な従来の課題を解決し、極めて簡単な構造で、製造コストも低減でき、風切音による騒音を小さく乃至は減少させる手すり柵を提供することを目的としたものである。 SUMMARY OF THE INVENTION Accordingly, the present invention aims to provide a handrail that solves such conventional problems, has an extremely simple structure, can reduce manufacturing costs, and reduces or reduces noise caused by wind noise. is there.
