【０００１】[0001]
本考案は、擁壁を段積み状に上方に構築する際に用いられる擁壁の各層支持装 置並びにそれを用いた擁壁の構造に関する。 The present invention relates to a device for supporting each layer of a retaining wall, which is used when a retaining wall is built up in a stack, and a structure of the retaining wall using the device.
【０００２】[0002]
道路脇等に構築される擁壁で、上下方向に層状に構築したものが知られている 。従来の擁壁の構築に際しては、図１１、図１２に示すように、擁壁の法面側に 側面視略Ｌ字型のエキスパンドメタル枠材１００を配置させ、縦壁側の鏡壁を法 面に沿うように立てて配置させるとともに地山側の底壁の後端側に敷網部材１０ ２の一端を連結させて地山側に展開して設けている。Ｌ字型エキスパンドメタル 枠材１００は、擁壁法面を形成する鏡壁１０４と、地山側に向けて水平に配置さ れる底壁１０６と、から構成されている。鏡壁１０４の擁壁構築時の内側にはエ キスパンドメタル枠材のストランド杆のピッチ孔を閉塞するマット部材１０８が 張付され、鏡壁からの土等の流出を止めている。Ｌ字型エキスパンドメタル枠材 １００には両端がフック状に曲げられたフック部１１２を有する鉄筋１１０が鏡 壁１０４と底壁１０６とに対して斜めに配置され、鏡壁１０４が地山側からの土 圧によって倒伏しないように支持している。 BACKGROUND ART Retaining walls constructed on the side of a road or the like, which are constructed in layers in a vertical direction, are known. When a conventional retaining wall is constructed, as shown in FIGS. 11 and 12, an expanded metal frame material 100 having a substantially L-shape in side view is disposed on the slope side of the retaining wall, and the mirror wall on the vertical wall side is formed. It is arranged upright along the surface, and one end of the laying net member 102 is connected to the rear end side of the bottom wall on the ground side to be developed and provided on the ground side. The L-shaped expanded metal frame member 100 is composed of a mirror wall 104 forming a slope of a retaining wall, and a bottom wall 106 arranged horizontally toward the ground. A mat member 108 for closing the pitch holes of the strand rods of the expanded metal frame material is attached to the inside of the mirror wall 104 when the retaining wall is constructed, to prevent outflow of soil and the like from the mirror wall. In the L-shaped expanded metal frame material 100, a reinforcing bar 110 having hook portions 112 whose both ends are bent in a hook shape is disposed obliquely with respect to the mirror wall 104 and the bottom wall 106, and the mirror wall 104 is formed from the ground side. They are supported so that they do not fall down due to earth pressure.
【０００３】 敷網部材１０２の一端側は、エキスパンドメタル枠材に係止された鉄筋１１０ の下側のフック部１１２に係止させた棒部材１１４に係止されている。敷網部材 は、その上に土を投入した際にＬ字型のエキスパンドメタル枠材の鏡壁側に向け て加わる土圧に対抗するようにＬ字型のエキスパンドメタルを水平方向に引張係 止する。図１１、図１３に示すように、Ｌ字型のエキスパンドメタルを擁壁法面 側に配置し、底壁と敷網部材の上面に該鏡壁の上端と同じ高さまで土を投入して 転圧し、その上面に次段のＬ字型のエキスパンドメタルと敷網部材を同様に配置 し土を投入して転圧する作業を繰り返して上方向に段積み層状に擁壁を構築する ものであった。[0003] One end of the laying net member 102 is locked to a bar member 114 locked to a hook portion 112 on a lower side of a reinforcing bar 110 locked to the expanded metal frame material. The laying net member holds the L-shaped expanded metal in a horizontal direction so as to oppose the earth pressure applied to the mirror wall side of the L-shaped expanded metal frame material when soil is put on it. I do. As shown in FIGS. 11 and 13, an L-shaped expanded metal is placed on the side of the retaining wall, and soil is poured into the bottom wall and the upper surface of the laying net member up to the same height as the upper end of the mirror wall. The next step was to place the L-shaped expanded metal and the laying net member on the upper surface in the same manner, put the soil in, and repeat the work of compacting, thereby constructing a retaining wall in a layered structure in the upward direction. .
【０００４】[0004]
しかしながら、エキスパンドメタル枠材は金属部材で重量が大きいので可搬性 が悪く搬送や施工作業時に多大な労力が必要であった。また、エキスパンドメタ ル枠材は金属板材を特殊加工したものであり、材料コストが高いとともに錆等も 生じ易くメッキや塗装等の防錆加工を施さなければならず高コストであった。さ らに、鏡壁支持用の鉄筋を鏡壁及び底壁に渡してそれぞれの壁にフック部をかけ る作業は面倒であり、特に鏡壁側を係止する場合にはフック部をマット部材に突 き通す作業が必要であった。これにより、作業能率が悪く多くの労力や時間が必 要であり、施工コストも高価なものであった。 However, the expanded metal frame material is a metal member and has a large weight, so its portability is poor, and a great deal of labor is required for transportation and construction work. The expanded metal frame material is a specially processed metal plate material, which requires high material costs and is liable to generate rust, so plating and painting must be performed to prevent rust. Furthermore, it is troublesome to pass the reinforcing bar for supporting the mirror wall to the mirror wall and the bottom wall and hook the hooks to the respective walls. It was necessary to pierce the road. As a result, the work efficiency was poor, a lot of labor and time were required, and the construction cost was expensive.
【０００５】 本考案は、上記課題に鑑みてなされたものでありその目的は、土圧に耐え得る 構造を有し、しかも可搬性が良く施工作業が簡単でコストが低廉である擁壁の各 層支持装置並びにそれを用いた擁壁の構造を提供することにある。The present invention has been made in view of the above-mentioned problems, and an object of the present invention is to provide a retaining wall which has a structure capable of withstanding earth pressure, is portable, has a simple construction work, and is inexpensive. An object of the present invention is to provide a layer support device and a retaining wall structure using the same.
