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.

In the handrail fence in which the handrails are arranged in the vertical direction, each baluster is a narrow plate, and the support column is also a narrow plate. The two handrails between the handrails or the columns are handrails arranged so as to have a “C” shape along the longitudinal direction of the crosspiece.
請求項2の発明は、間隔を空けて設けた2本の支柱の上下に桟を夫々わたして設け、これらの当該上下の桟の間に、上下の桟に沿って等間隔で多数の手すり子を縦方向に並べた手すり柵において、各手すり子又は支柱を含むこれらの一つおき毎に細幅板とし、これらの各手すり子又は支柱の細幅板は前記桟の長手方向に直交するよう配置され、これらの手すり子又は支柱の間の各手すり子は丸棒から成る、手すり柵とした。 According to the invention of claim 2, a crosspiece is provided on the upper and lower sides of two struts provided at intervals, and a large number of handrails are provided at equal intervals along the upper and lower crosspieces between the upper and lower crosspieces. In the handrail fence in which the handrails are arranged in the vertical direction, every other one including each handrail or pillar is a narrow plate, and the narrow plate of each handrail or post is perpendicular to the longitudinal direction of the rail. Arranged, each balustrade between these balustrades or struts was a balustrade fence consisting of round bars.
請求項3の発明は、間隔を空けて設けた2本の支柱の上下に桟を夫々わたして設け、これらの当該上下の桟の間に、上下の桟に沿って等間隔で多数の手すり子を縦方向に並べた手すり柵において、各手すり子を細幅板とし、隣接する各手すり子は前記桟の長手方向に沿って相互に正、逆の「ハ」の字となるように配設された、手すり柵とした。 According to the invention of claim 3, a crosspiece is provided above and below two struts provided at intervals, and a large number of handrails are equally spaced along the upper and lower crosspieces between the upper and lower crosspieces. In the handrail fence in which the bars are arranged in the vertical direction, each handrail is a narrow plate, and adjacent handrails are arranged so as to be in the shape of the opposite “C” along the longitudinal direction of the crosspiece. It was a handrail fence.
請求項4の発明は、前記「ハ」の字となるよう配設された各手すり子の細幅板の、前記桟の長手方向に直交する方向に対する傾斜角度は30度〜70度である、請求項1又は3に記載の手すり柵とした。 In the invention of claim 4, an inclination angle of the narrow plate of each handrail arranged so as to have the shape of “C” is 30 degrees to 70 degrees with respect to a direction orthogonal to the longitudinal direction of the crosspieces. The railing fence according to claim 1 or 3.
請求項1、2、3及び4の各発明によれば、風速や、風向きがどのような状態であっても、高い周波数の騒音や風切音による騒音を小さく乃至は減音することができる。また、手すり柵を構成する手すり子を上記のように細幅板又は丸棒としているため、簡単な構造で、製造コストも低減できる。さらに、従来のように、手すり柵が製造された上に、他の部材を加えて取り付けることなく、騒音の発生しない手すり柵を提供できる。 According to the first, second, third, and fourth aspects of the invention, it is possible to reduce or reduce noise caused by high-frequency noise and wind noise regardless of the wind speed and wind direction. . Moreover, since the balustrade which comprises a handrail fence is made into the narrow board or the round bar as mentioned above, it can also reduce manufacturing cost with a simple structure. Further, as in the prior art, a handrail can be provided that does not generate noise without having to be added with other members after the handrail has been manufactured.
