Description

この発明は、落石防止柵、特に、支柱の山側への倒れ込みを阻止する支持柱を設ける必要がなく、支柱の山側への倒れ込みを阻止する谷側ワイヤーが張れない場合であっても、支柱の山側への倒れを確実に阻止することができ、しかも、支持柱の傾斜角度を自在に調整することができ、さらに、支柱の谷側への倒れ込み阻止効果を増大させることができる落石防止柵に関するものである。   The present invention eliminates the need for a rockfall prevention fence, in particular, a support column that prevents the column from falling to the mountain side, and even if the trough side wire that prevents the column from falling to the mountain side cannot be stretched, A rock fall prevention fence that can surely prevent falling to the mountain side, can adjust the inclination angle of the support column freely, and can further increase the effect of preventing the column from falling to the valley side Is.

道路等への落石を防止する落石防止柵の一例が特許文献１に開示されている。以下、この落石防止柵を従来落石防止柵Ａといい、図面を参照しながら説明する。   An example of a rockfall prevention fence that prevents rockfall on a road or the like is disclosed in Patent Document 1. Hereinafter, this rock fall prevention fence will be referred to as a conventional rock fall prevention fence A and will be described with reference to the drawings.

図５は、従来落石防止柵Ａを示す側面図である。   FIG. 5 is a side view showing a conventional rock fall prevention fence A. FIG.

図５において、１１は、斜面１２に所定間隔をあけて起倒可能に構築された支柱、１３は、支柱１１の上端部と山側（Ｍ）の斜面１２との間に張られた山側ワイヤー、１４は、隣接する支柱１１の上端部間に通された上部ワイヤー、１５は、隣接する支柱１１の下端部間に通された下部ワイヤー、１６は、上部ワイヤー１４と下部ワイヤー１５との間に張られた、落石を受け止める金網、１７は、支柱１１の山側（Ｍ）への倒れ込みを阻止する支持柱である。支持柱１７の上端は、支柱１１の下部に固定され、支持柱１７の下端は、山側（Ｍ）の斜面１２に当接され、これによって、支柱１１の山側（Ｍ）への倒れ込みが阻止される。   In FIG. 5, 11 is a support column constructed so as to be able to rise and fall at a predetermined interval on the slope 12, and 13 is a mountain-side wire stretched between the upper end portion of the support column 11 and the mountain side (M) slope 12, 14 is an upper wire passed between the upper ends of adjacent struts 11, 15 is a lower wire passed between the lower ends of adjacent struts 11, and 16 is between the upper wire 14 and the lower wire 15. A stretched wire mesh 17 for catching falling rocks is a support column that prevents the support 11 from falling onto the mountain side (M). The upper end of the support column 17 is fixed to the lower portion of the support column 11, and the lower end of the support column 17 is brought into contact with the slope 12 on the mountain side (M), thereby preventing the column 11 from falling into the mountain side (M). The

落石防止柵の別の例が特許文献２に開示されている。以下、この落石防止柵を従来落石防止柵Ｂといい、図面を参照しながら説明する。   Another example of a rockfall prevention fence is disclosed in Patent Document 2. Hereinafter, this rockfall prevention fence will be referred to as a conventional rockfall prevention fence B and will be described with reference to the drawings.

図６は、従来落石防止柵Ｂを示す側面図である。   FIG. 6 is a side view showing a conventional rock fall prevention fence B. FIG.

図６において、１８は、斜面１９に所定間隔をあけて構築された支柱、２０は、支柱１８の上端部と山側（Ｍ）の斜面１９との間に張られた山側ワイヤー、２１は、支柱１８の上端部と谷側（Ｖ）の斜面１９との間に張られた谷側ワイヤー、２２は、支柱１８間に張られた、落石を受け止める金網である。   In FIG. 6, 18 is a column constructed with a predetermined interval on the slope 19, 20 is a mountain wire stretched between the upper end of the column 18 and the mountain side (M) slope 19, and 21 is a column. A trough side wire 22, which is stretched between the upper end of 18 and the slope 19 on the trough side (V), is a wire net that stretches between the columns 18 and catches falling rocks.

上記従来落石防止柵Ａによれば、斜面１２からの落石は、金網１６により受け止められる。この際、支柱１１は、山側ワイヤー１３により引っ張られているので、支柱１１が谷側（Ｖ）に倒れるおそれはない。   According to the conventional rock fall prevention fence A, rock fall from the slope 12 is received by the wire mesh 16. At this time, since the column 11 is pulled by the mountain-side wire 13, there is no possibility that the column 11 falls to the valley side (V).

また、落石が金網１６に衝突すると、山側ワイヤー１３に引張力が作用し、その反動で支柱１１には、支柱１１が山側（Ｍ）に倒れ込む力が作用する。しかし、支持柱１７の下端が山側（Ｍ）の斜面１２に当接する結果、支柱１１が山側（Ｍ）に倒れ込むおそれはない。   Further, when the falling rock collides with the wire mesh 16, a tensile force acts on the mountain-side wire 13, and the reaction force causes the column 11 to fall on the mountain side (M). However, as a result of the lower end of the support column 17 coming into contact with the slope 12 on the mountain side (M), there is no possibility that the column 11 will fall into the mountain side (M).

支柱１１の山側（Ｍ）への倒れ込みは、山側ワイヤー１３上に雪が積もり、その積雪荷重により山側ワイヤー１３に下向きの力が作用した場合等にも生じる。   The falling of the support 11 to the mountain side (M) also occurs when snow accumulates on the mountain side wire 13 and a downward force acts on the mountain side wire 13 due to the snow load.

上記従来落石防止柵Ｂによれば、落石は、金網２２により受け止められる。この際、支柱１８は、山側ワイヤー２０により引っ張られているので、支柱１８が谷側（Ｖ）に倒れるおそれはない。   According to the conventional rock fall prevention fence B, the rock fall is received by the wire mesh 22. At this time, since the column 18 is pulled by the mountain-side wire 20, there is no possibility that the column 18 falls to the valley side (V).

また、従来落石防止柵Ａにおけると同様に、斜面１９からの落石が金網２２に衝突すると、山側ワイヤー２０に引張力が作用し、その反動で支柱１８には、支柱１８が山側（Ｍ）に倒れ込む力が作用するが、支柱１８は、谷側ワイヤー２１により引っ張られているので、支柱１８が山側（Ｍ）に倒れ込むおそれはない。   Further, as in the conventional rock fall prevention fence A, when the rock fall from the slope 19 collides with the wire mesh 22, a tensile force acts on the mountain side wire 20, and the column 18 is moved to the mountain side (M) by the reaction. Although a falling force acts, the support column 18 is pulled by the trough-side wire 21, so that the support column 18 does not fall into the mountain side (M).

しかしながら、従来落石防止柵Ａによれば、山側（Ｍ）の起伏に応じて、支持柱１７の長さを変える必要があるので、この分、落石防止柵の構築費用が増加するといった問題があった。   However, according to the conventional rock fall prevention fence A, since it is necessary to change the length of the support column 17 according to the undulations on the mountain side (M), there is a problem that the construction cost of the rock fall prevention fence increases accordingly. It was.

また、従来落石防止柵Ｂは、従来落石防止柵Ａの有する上記のような問題はないが、場所的に谷側ワイヤー２１を張ることができない場合があるといった問題があった。   Further, the conventional rock fall prevention fence B does not have the above-mentioned problem that the conventional rock fall prevention fence A has, but has a problem that the valley-side wire 21 may not be stretched in some places.

従って、この発明の目的は、支柱の山側への倒れ込みを阻止する支持柱を設ける必要がなく、しかも、支柱の山側への倒れ込みを阻止する谷側ワイヤーが張れない場合であっても、支柱の山側への倒れを確実に阻止することができ、さらに、支柱の傾斜角度を自在に調整することができる落石防止柵を提供することにある。   Therefore, the object of the present invention is not to provide a support column for preventing the column from falling to the mountain side, and even if the trough side wire for preventing the column from falling to the mountain side cannot be stretched, An object of the present invention is to provide a rockfall prevention fence that can surely prevent the mountain from falling down and that can freely adjust the inclination angle of the column.

この発明は、上記目的を達成するためになされたものであり、下記を特徴とする。   The present invention has been made to achieve the above object, and is characterized by the following.

請求項１に記載の発明は、斜面に構築される落石防止柵において、前記斜面に所定間隔をあけて構築される支柱と、前記支柱の上端部と山側の前記斜面との間に張られる山側ワイヤーと、前記支柱間に張られた、落石を受け止める金網と、伸縮可能な連結部材とを備え、前記連結部材の上端は、前記支柱に固定され、前記連結部材の下端は、谷側の前記斜面に固定されていることに特徴を有するものである。   The invention according to claim 1 is a rockfall prevention fence constructed on a slope, and a mountain side stretched between a pillar constructed with a predetermined interval on the slope, and an upper end portion of the pillar and the slope on the mountain side A wire, a wire mesh that catches falling rocks, and a telescopic connecting member, the upper end of the connecting member is fixed to the post, and the lower end of the connecting member is the trough side It is characterized by being fixed to a slope.

請求項２に記載の発明は、請求項１に記載の発明において、前記連結部材は、ターンバックルからなっていることに特徴を有するものである。   The invention described in claim 2 is characterized in that, in the invention described in claim 1, the connecting member is formed of a turnbuckle.

請求項３に記載の発明は、請求項１または２に記載の発明において、前記連結部材の下端は、前記支柱の基台の谷側に固定されていることに特徴を有するものである。   The invention described in claim 3 is characterized in that, in the invention described in claim 1 or 2, the lower end of the connecting member is fixed to the valley side of the base of the support column.

この発明によれば、支柱の山側への倒れ込みを阻止する支持柱を設ける必要がなく、支柱の山側への倒れ込みを阻止する谷側ワイヤーが張れない場合であっても、支柱の山側への倒れを確実に阻止することができ、しかも、支柱の傾斜角度を自在に調整することができ、さらに、支柱の谷側への倒れ込み阻止効果を増大させることができる。   According to the present invention, it is not necessary to provide a support column that prevents the column from falling to the mountain side, and even if the trough side wire that prevents the column from falling to the mountain side cannot be stretched, the column falls to the mountain side. Can be reliably prevented, the inclination angle of the support can be freely adjusted, and the effect of preventing the support from falling to the valley side can be increased.

この発明の落石防止柵の一実施態様を、図面を参照しながら説明する。   An embodiment of the rockfall prevention fence of the present invention will be described with reference to the drawings.

図１は、この発明の落石防止柵において、連結部材を伸ばした状態を示す側面図、図２は、この発明の落石防止柵において、連結部材を縮めた状態を示す側面図である。   FIG. 1 is a side view showing a state in which a connecting member is extended in the rockfall prevention fence of the present invention, and FIG. 2 is a side view showing a state in which the connecting member is contracted in the rockfall prevention fence of the present invention.

図１および図２において、１は、斜面２に所定間隔をあけて構築された支柱である。支柱１は、基台３上にピン８を中心として起倒可能に固定されている。基台３は、斜面２に打ち込まれたアンカー４によって斜面２に固定されている。５は、支柱１の上端部と山側（Ｍ）の斜面２との間に張られた山側ワイヤー、６は、支柱１間に張られた、落石を受け止める金網である。   In FIG. 1 and FIG. 2, 1 is a support | pillar constructed | assembled on the slope 2 at predetermined intervals. The support column 1 is fixed on the base 3 so that it can be tilted around a pin 8. The base 3 is fixed to the slope 2 by an anchor 4 driven into the slope 2. Reference numeral 5 denotes a mountain-side wire stretched between the upper end portion of the support column 1 and the mountain-side (M) slope 2, and reference numeral 6 denotes a wire mesh stretched between the support columns 1 for receiving a falling rock.

７は、支柱１と支柱１の基台３の谷側（Ｖ）との間に固定された伸縮可能な連結部材である。すなわち、連結部材７の上端は、支柱１に固定され、連結部材７の下端は、支柱１の基台３の谷側（Ｖ）に固定されている。連結部材７が固定されている基台３部分にもアンカー４が打ち込まれている。この例では、連結部材７は、ターンバックルからなっているが、支柱１と谷側（Ｖ）の斜面２との間を剛に連結かつ伸縮可能なものであれば、ターンバックルに限定されない。   Reference numeral 7 denotes an extendable connecting member fixed between the support column 1 and the valley side (V) of the base 3 of the support column 1. That is, the upper end of the connecting member 7 is fixed to the column 1, and the lower end of the connecting member 7 is fixed to the valley side (V) of the base 3 of the column 1. The anchor 4 is also driven into the base 3 portion to which the connecting member 7 is fixed. In this example, the connecting member 7 is formed of a turnbuckle. However, the connecting member 7 is not limited to the turnbuckle as long as it can be rigidly connected and stretchable between the support column 1 and the slope 2 on the valley side (V).

この発明の落石防止柵によれば、斜面２からの落石は、金網６により受け止められる。この際、支柱１は、山側ワイヤー５により引っ張られているので、支柱１が谷側（Ｖ）に倒れるおそれはない。しかも、支柱１の基台３と谷側（Ｖ）の斜面２との間に、連結部材７が固定されているので、支柱１の谷側（Ｖ）への倒れ込み阻止効果は、増大する。   According to the rockfall prevention fence of the present invention, rockfall from the slope 2 is received by the wire mesh 6. At this time, since the column 1 is pulled by the mountain-side wire 5, there is no possibility that the column 1 falls to the valley side (V). And since the connection member 7 is being fixed between the base 3 of the support | pillar 1 and the slope 2 of the trough side (V), the fall prevention effect to the trough side (V) of the support | pillar 1 increases.

また、落石が金網６に衝突すると、山側ワイヤー５に引張力が作用し、その反動で支柱１には、支柱１が山側（Ｍ）に倒れ込む力が作用する。しかし、連結部材７が支柱１と谷側（Ｖ）の斜面２との間に固定されているので、支柱１が山側（Ｍ）に倒れ込むおそれはない。   Further, when the falling rock collides with the wire mesh 6, a tensile force acts on the mountain side wire 5, and the reaction force causes the column 1 to fall on the mountain side (M). However, since the connecting member 7 is fixed between the column 1 and the slope 2 on the valley side (V), there is no possibility that the column 1 falls to the mountain side (M).

また、連結部材７が谷側ワイヤー２１（図６参照）と同様な機能を発揮するので、場所的に谷側ワイヤー２１を張ることができない場合であっても容易に対応可能である。   Moreover, since the connection member 7 exhibits the same function as the trough-side wire 21 (see FIG. 6), it is possible to easily cope with the case where the trough-side wire 21 cannot be stretched locally.

さらに、連結部材７は伸縮可能であるので、斜面２に対する支柱１の傾斜角度を自在に調整することができる。すなわち、図１に示すように、斜面２の傾斜角度（θ１）が大きい場合には、連結部材７を伸ばして長さ（Ｌ１）とし、図２に示すように、斜面２の傾斜角度（θ２）が小さい場合には、連結部材７を縮めて長さ（Ｌ２）とする。この結果、斜面２の傾斜角度によらず、水平線に対する支柱１の傾斜角度（θ３）を一定に維持することができる。   Furthermore, since the connecting member 7 can expand and contract, the inclination angle of the support column 1 with respect to the inclined surface 2 can be freely adjusted. That is, as shown in FIG. 1, when the inclination angle (θ1) of the slope 2 is large, the connecting member 7 is extended to a length (L1), and the inclination angle (θ2) of the slope 2 is shown in FIG. ) Is small, the connecting member 7 is contracted to a length (L2). As a result, the inclination angle (θ3) of the support column 1 with respect to the horizontal line can be maintained constant regardless of the inclination angle of the slope 2.

以上説明したように、この発明によれば、支柱１の山側（Ｍ）への倒れ込みを阻止する支持柱を設ける必要がなく、場所的に支柱１の山側（Ｍ）への倒れ込みを阻止する谷側ワイヤーが張れない場合であっても、支柱１の山側（Ｍ）への倒れを確実に阻止することができ、さらに、支柱１の傾斜角度を自在に調整することができ、しかも、支柱１の谷側（Ｖ）への倒れ込み阻止効果を増大させることができる。   As described above, according to the present invention, there is no need to provide a support column for preventing the support column 1 from falling to the mountain side (M), and the valley for preventing the support column 1 from falling to the mountain side (M) is located. Even when the side wire cannot be stretched, the column 1 can be reliably prevented from falling to the mountain side (M), and the inclination angle of the column 1 can be freely adjusted. The fall prevention effect to the valley side (V) can be increased.
