Description

【０００１】
【発明の属する技術分野】
本発明は、所定間隔を隔てて隣接した建物にわたって架設される廊下用手摺りの連結構造に関する。
【０００２】
【従来の技術】
大きな建物になると、大きな地震を受けたときに、建物の水平方向両端間で捩じりや収縮等を生じ、一部の箇所に大きな応力が集中し、それが原因で建物に亀裂などを生じ、建物全体が破損する問題があった。
【０００３】
そこで、近年では、建物を構築する場合に、上述のような大きな応力の集中を回避するために、水平方向で複数の建物に分割して構築し、それらの隣接した建物間を廊下等で繋いでいる。
ところが、水平方向の揺れによる影響を回避するために、下方では隣接間隔が狭くても、上方になるほど隣接間隔が広くなって危険なため、連結した廊下の両側に、手摺りを設ける必要が生じてきた。
【０００４】
このような手摺りとして、従来では、図１０の正面図、図１１の要部の一部切欠平面図、図１２の要部の縦断面図に示すような構成が採用されていた。
すなわち、隣接した建物Ａ，Ｂの一方の建物Ａに、その建物Ａ側の廊下の両側壁０１それぞれに連なるように、蝶番０２を介して鉛直方向の軸芯Ｐ１周りで揺動可能に第１の手摺り部材０３が取り付けられている。
【０００５】
他方の建物Ｂに、その建物Ｂ側の廊下の両側壁０１それぞれに連なるように、蝶番０２を介して鉛直方向の軸芯Ｐ２周りで揺動可能に第２の手摺り部材０４が取り付けられている。
【０００６】
第１の手摺り部材０３の遊端側の上下それぞれに、コの字状のガイド部材０５が取り付けられている。
両側の第１の手摺り部材０３それぞれの外側に位置させて、ガイド部材０５内に、両建物Ａ，Ｂが互いに対向する水平方向に移動可能に第２の手摺り部材０４が嵌入されている。
【０００７】
ガイド部材０５に、先端を第２の手摺り部材０４に当接するストッパー部材０６が取り付けられ、第２の手摺り部材０４の揺動範囲を規制するように構成されている。
【０００８】
第１および第２の手摺り部材０３，０４それぞれに、互いに高さを異ならせて、緩衝ゴム０７が取り付けられ、第１および第２の手摺り部材０３，０４が直接当接して損傷することを防止できるように構成されている。
【０００９】
【発明が解決しようとする課題】
しかしながら、従来例の場合、隣接する建物Ａ，Ｂの互いに対向する水平の直線方向と、それに直交する水平方向との二次元方向での振動に対しては有効であるが、両建物Ａ，Ｂが上下方向にずれたり、捩じれるような力がかかった場合、第１および第２の手摺り部材０３，０４を介して両建物Ａ，Ｂ間で力が直接的に伝達されてしまう欠点があった。
【００１０】
本発明は、このような事情に鑑みてなされたものであって、三次元方向での振動に対して、隣接する建物間で力が伝達されることを抑制し、地震に際しての廊下用手摺りに起因する建物の損壊を有効に防止できるようにすることを目的とする。
【００１１】

BACKGROUND OF THE INVENTION
The present invention relates to a connecting structure for handrails for hallways constructed over buildings adjacent to each other at a predetermined interval.
[0002]
[Prior art]
When it becomes a big building, when it receives a big earthquake, it causes torsion and shrinkage between the horizontal ends of the building, and a large stress concentrates in some places, which causes cracks in the building, There was a problem that the whole building was damaged.
[0003]
Therefore, in recent years, when building a building, in order to avoid the concentration of large stress as described above, the building is divided into a plurality of buildings in the horizontal direction and the adjacent buildings are connected by a corridor or the like. It is out.
However, in order to avoid the effects of horizontal shaking, even if the adjacent interval is narrow at the bottom, it is dangerous because the adjacent interval becomes wider as it goes upward, so it is necessary to provide handrails on both sides of the connected corridors. I came.

A second guide member 7 is attached to the member 6 so as to be swingable about the longitudinal axis Q.
[0021]
Positioned on the outer sides of the first handrail members 3 on both sides, the second building A and B is movable between the first and second guide members 6 and 7 in the horizontal direction opposite to each other. A handrail member 5 is inserted, and the second guide member 7 and the second handrail member 5 are connected to each other through a temporary set screw 8.
[0022]
As a result, for example, when a large force is applied due to an earthquake with a seismic intensity of 4 or 5, the temporary set screw 8 is broken, so that the connection is released and the second guide member 7 freely swings, The first handrail member 3 and the second handrail member 5 allow relative displacement in the three-dimensional direction, and the first and second hands are horizontally and vertically opposed to each other. While moving the sliding members 3 and 5 relative to each other, the second handrail member 5 is moved away from the first handrail member 3 in the horizontal direction perpendicular to the horizontal direction in which both buildings A and B face each other. It is possible to block the transmission of impact force between the two buildings A and B.
[0023]
The first and second handrail members 3 and 5 are attached with the shock absorbing rubber 9 at different heights, and the first and second handrail members 3 and 5 are in direct contact with each other and are damaged. It is configured to prevent it.

FIG. 4 is an enlarged front view showing the mounting configuration of the first elastic member, and FIG. 5 is a partially cutaway enlarged plan view of FIG. 4, and the first elastic member 2 is made of a compression coil spring made of stainless steel. In addition, it is configured to be able to be displaced in a three-dimensional direction by expansion and contraction and bending deformation with respect to a force larger than the set value. The first elastic member 2 is covered with a cover 10 made of silicon rubber pipe. The second elastic member 4 is configured in the same manner.
[0025]
A channel member 13 which is attached to an anchor female screw 11 on the side wall 1 on the side of the building A via a washer and a spring washer (both not shown in the figure number) and a bolt 12, and a channel shape of the first handrail member 3. An insertion hole 14 through which the first elastic member 2 can be inserted is formed in each of the vertical frames 3a.
[0026]
A nut 15 is forcibly fitted to the vertical frame 3a of the first handrail member 3 so as to correspond to the insertion hole 14, and the first elastic member 2 is screwed into the nut 15 as a male screw. The first O-ring 16 prevents it from coming off.
[0027]

【The invention's effect】
As described above, according to the connection structure of the handrail for the corridor between the adjacent buildings of the invention according to claim 1, the displacement of the adjacent buildings in the horizontal direction facing each other is the first handrail member. Absorbed by displacement with the second handrail member, and absorbs horizontal and vertical displacement and twist perpendicular to the direction in which adjacent buildings face each other by displacement of the elastic material. As a result, it is possible to suppress the transmission of force between adjacent buildings, and to effectively prevent damage to buildings due to handrails for corridors during an earthquake.
[0038]
According to the connection structure of the handrail for the corridor between the adjacent buildings according to the second aspect of the invention, the displacement of the adjacent buildings in the horizontal direction opposite to each other is detected by the first handrail member and the second handrail. The horizontal displacement perpendicular to the direction in which adjacent buildings face each other is absorbed by the displacement with the sliding member, and the first handrail member swings around the vertical axis and the elastic material Because it absorbs by displacement and further absorbs displacement and twist in the vertical direction of adjacent buildings by displacement of elastic material, force is transmitted between adjacent buildings against vibration in the three-dimensional direction.
