【発明の属する技術分野】本発明は土留工等に使用される石詰籠に関する。
【０００２】
【従来の技術】従来の、菱形金網製「ふとん籠」は直方体であって、垂直壁状或いは階段状に積み上げて使用されてきたが、景観、構造、流木、植生等の観点から、スロープ形状をより評価する場合が多い。併しながら菱形金網で傾斜型籠体を製作するのは、手間が掛かり過ぎて実務上、不可である。そもそも菱形金網は強度の観点からいっても軟弱であって傾斜型籠体の製作には不向きである。
【０００３】
また、従来の菱形金網製「ふとん籠」の長さは４ｍ止まりであって、長い区間に敷設する場合には、隣接の籠同士を連結する手間を削減するため、また籠間のズレ発生の構造的原因を排除するため、また中網の重複を排除するため、長尺ものが求められている。傾斜型石詰籠に関しても事情は同じであって長尺ものが求められる。
【０００４】
【発明が解決しようとする課題】本発明の課題とするところは、石詰籠に関する傾斜型と長尺の要望を同時に解決するため、「長尺で傾斜型の石詰籠」を提供しようとするものである。更に、本発明に係る「長尺で傾斜型の石詰籠」を連設する場合、直線型連結に加えて、折れ線型連結にも対応できる連結方法を提供して、「長尺で傾斜型の石詰籠」（以後、長傾籠と略称する。）の実施に万全を期したい。
【０００５】
【課題を解決するための手段】上記目的を達成するために次の手段を講じる。先ず長傾籠の胴網の製作に関して。
（イ）長傾籠の胴網は所定仕様の亀甲金網で形成する。亀甲金網は列線の「ねじり」を「かど」にすれば容易にＵ字状に折曲される。更に亀甲金網は剛性大であり、折曲部分は自立しＵ字状形状を保持するので、前網、底網、後網からなる胴網が効率良く形成される。
（ロ）この胴網は長手方向に於いて一体構造であるから、従来の菱形金網製ふとん籠工に現われた「籠同士の連結作業」「ズレ」「側面網の重複」は無くなる。

台形中網の製作に関して次の手段を講じる。
（イ）長傾籠用台形中網は所定仕様の亀甲金網で形成する。長方形に切断した亀甲金網に於いて、上辺の網目から斜め位置に相接する網目を、逐一通過して下辺の網目に至る斜線を切断線として、台形の傾斜側辺を形成する。
（ロ）台形中網は上辺＜下辺とし、傾斜側辺で籠の前面を構成する。長傾籠の前網は台形中網の勾配で沿って後寄りに傾斜する。傾斜の変化には網目の縦横比を変化させて対応するのが基本であるが、階段状にずらして積み上げる方法や、直方体石詰籠と傾斜型を併用する方法や、敷設地面に傾斜を付けて対応する。
（ハ）次に胴網の所定位置に台形中網を配置し、結合具を介して結合して上面開放の石詰空間を形成し。石詰め後、蓋網を被着すれば長傾篭の製作は完了する。

長傾籠の直線型連結に関して次の手段を講じる。
（イ）台形中網を、胴網両端部の縁から内側に所定間隔を置いて配設して、胴編両端部に夫々張出部を留保する。
（ロ）長傾籠の連結に当たっては、対向する張出部の縁同士を、重ね合わせ、結合具を介して結合する。連結部には両方の張出部を併せて１個の石詰空間が形成される。石詰め後、蓋網を被着すれば長傾篭の連結は完了する。
（ハ）連結部のズレや中網の重複は最早見られない。
【００１０】
長傾籠の折れ線型連結に関して次の手段を講じる。
（イ）折れ線型連結に於いては、相連結する長傾籠底面間に空隙が生じるので、亀甲金網製底面連結網を用意する。網目は強固なので、長傾籠の底面の縁を、底面補填網の任意の網目に、即ち任意角度で結合することが出来る。
（ロ）前面及び背面に生じる空隙の補填用に亀甲金網製連結網を用意する。列線の「ねじり」を「かど」にすれば容易に折曲出来るので、幅調整は自在である。更に［図８］に示すように前面連結網は２部材からなる合成構造にして形状変化も可能にする。
（ハ）長傾籠と連結網の当接部を、結合具を介して結合すれば、石詰空間が形成され、石詰め後、蓋網を被着すれば長傾篭の連結は完了する。

【発明の実施の形態】以下、本発明の実施の形態を図面により説明する。
［図１］は本発明の長傾籠用亀甲金網２の一例を示す平面図である。本例の亀甲金網２の仕様は、列線２１は表面処理鋼線で、線径は４ｍｍ、網目３は（左右相対向するねじりの間隔）×（上下相対向する頂角の距離）＝８０×１００ｍｍである。略２ｍ３００幅（＝８０ｍｍ×２８．５目）に編んだ亀甲金網２を長尺のままで敷地に展開し、「ねじり」２２を逐次通過する折曲線２３を「かど」にしてＵ字状に折り曲げる。コイル状金網の長さは機械によるが最大５０ｍで、カットして輸送する場合は８ｍが一般である。
【００１３】
［図２］は本発明に係る台形中網用亀甲金網２を示す平面図である。本例に於いて台形中網４を形成する亀甲金網２は、［図１］と同じ仕様で、長さ５００ｍｍに切断した長方形のものである。上辺の網目３から斜め位置に相接する網目３１を、逐一通過して下辺の網目３２に至る斜線を切断線５として、台形の傾斜側辺を形成する。切断線５が亀甲金網２の長方形の中心網目３３を通過すれば、分割されて形成された二つの台形は合同であり、製作は効率的である。
【００１４】
［図３］は本発明の長傾籠１の胴網１１を形成する態様を示す斜視図である。［図１］に記した仕様の亀甲金網２を長尺のまま敷地に展開し、折曲線２３を折り曲げて、列線の「ねじり」を「かど」にして断面Ｕ字状を形成する。本例では網目３が８ツの前網７、６ツ半の後網８と１６コの底網９とを形成する。本亀甲金網２は４ｍｍ列線２１で剛性大であるから、折曲された形状は保持される。胴網１１は長手方向に於いて一体構造であるから、従来のふとん籠工に現われた籠同士の連結作業やズレ、中網の重複は無くなった。
【００１５】
［図４］は本発明の長傾籠１の組み立て態様を示す斜視図である。［図２］に示した台形中網４を、傾斜辺を前面にして、胴網１１の所定位置に、例えば１ｍ間隔で配置する。次に、結合金具例えば螺旋状鉄線を介して、台形中網４の縁を前網７、後網８及び底網９と結合すれば組み立ては完了、複数の石詰空間１３が形成される。前網７は台形中網４の傾斜辺に結合しているので、後ろ寄りに傾斜していることを特徴とする。
【００１６】
［図５］は本発明の長傾籠１の製作完了態様を示す斜視図である。石詰空間１３に石詰め終了後、蓋網１０を被せ結合具１２を介して前網７と後網８の上縁に結合すれば、長傾籠の製作は完了する。
【００１７】
［図６］は本発明の長傾籠１、１を直線型連結する態様を示す斜視図である。胴網１１の両端部に於いて、台形中網４を胴網１１の縁から離して配設して、張出部１５、１５を留保し、縁同士を一目程度重ね合わして結合する。連結部に於いては両者の張出部１５、１５を併せて１個の石詰空間１３が形成される。石詰後、蓋網１０を被着して連結は完了する。かくて連結作業の能率化と工事費の削減が実現される。
【００１８】
［図７］は本発明の長傾籠１、１を折れ線型連結する態様を示す平面図である。
（イ）折れ線状に配置された長傾籠１、１の間隙に、亀甲金網２からなる適宜大きさの連結網６を敷き、長傾籠１、１の底網９、９の縁を、結合具１２を介して連結網６に結合する。連結網６の亀甲網目３は頑丈なので、任意の網目に結合出来る。従って底網９、９は任意方向の折れ線に結合出来る。
（ロ）次に長傾籠１、１の連結部前面及び背面の間隙を、亀甲金網２からなる適宜大きさの連結網６１、６２で補完すれば、連結部は上面開放の石詰空間１３となる。石詰後、蓋網１０を被着して連結は完了する。
【００１９】
［図８］は本発明の長傾籠１の折れ線型連結に係る前面連結網６１の他の例を示す説明図である。この例では、前面連結網６１は２枚の長方形の亀甲金網２、２で合成され、結合具１２を介して結合される。斜線結合に依って台形に形状修正出来る。また夫々の亀甲金網２、２に関して、列線の「ねじり」を「かど」にすれば容易に折り曲げられるので、側縁の折曲に依って幅を自在に調整出来る。かくて本例の前面連結網６１を「図７］の折れ線型連結の前面間隙に嵌着出来る。
【００２０】
【発明の効果】本発明の長傾籠を使用すれば、元々、景観、構造、流木、植生等々の観点から評価されて来たスロープ形状の石詰籠工は、長尺化により更なるメリットを重ねるようになった。即ち従来の「ふとん籠」工に現われた籠同士の連結作業と中網の重複、連結場所に現われた「ズレ」の構造的原因は無くなった。また更に本発明に係る長傾籠の連結工法の開発は長傾籠の実施を支援するものである。尚、長傾籠の地網とした亀甲金網は強度、屈撓性に関して、菱形金網より格段に優っている。本発明の長傾籠は、地網の長所を十分保持しながらスロープ形状と長尺籠の長所を兼備したものである。

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stone basket used for earth retaining work and the like.
[0002]
2. Description of the Related Art Conventionally, "futon baskets" made of diamond-shaped wire mesh are rectangular parallelepipeds and have been used by being stacked in a vertical wall shape or a step shape. However, from the viewpoint of landscape, structure, driftwood, vegetation, etc., a slope shape is used. Is often evaluated more. At the same time, it is not practical in practice to manufacture an inclined basket with a diamond-shaped wire mesh because it takes too much work. In the first place, a diamond-shaped wire mesh is weak even from the viewpoint of strength, and is not suitable for manufacturing a tilted basket.
[0003]
In addition, the length of the conventional "futon cage" made of diamond-shaped wire mesh is limited to 4 m, and when laying in a long section, in order to reduce the labor for connecting adjacent cages, a gap between the cages may be generated. In order to eliminate structural causes and to eliminate duplication of the net, long ones are required. The situation is the same for inclined stone baskets, and long ones are required.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to provide a "long and inclined type stone basket" in order to simultaneously solve the inclined type and the long request for the stone basket. Is what you do. Furthermore, in the case of continuously installing the “long and inclined type stone basket” according to the present invention, in addition to the linear type connection, a connection method capable of coping with the broken line type connection is provided. I want to make sure that Ishizume baskets (hereafter abbreviated as long baskets) are implemented.
[0005]
To achieve the above object, the following means are taken. First of all, regarding the production of the long net.
(B) The body net of the long inclined basket is formed of a turtle shell wire mesh of a predetermined specification. The tortoiseshell wire net can be easily bent into a U-shape by changing the "twist" of the column lines to a "corner". Furthermore, since the turtle shell wire mesh is large in rigidity and the bent portion is self-supporting and retains a U-shaped shape, a trunk net consisting of a front net, a bottom net, and a rear net is efficiently formed.
(B) Since this trunk net is of an integral structure in the longitudinal direction, the "connection work between cages", "displacement" and "overlap of side nets" appearing in a conventional diamond-shaped wire mesh futon cage are eliminated.
[0006]
[Patent Document 1] JP-A-11-172648 Long stone basket
The following measures are taken for the production of trapezoidal nets.
(A) The trapezoidal mesh for long baskets is formed of a tortoise-mesh mesh of specified specifications. In the tortoise-shaped wire mesh cut into a rectangle, a trapezoidal inclined side is formed by setting a diagonal line passing through the mesh adjacent to the oblique position from the mesh on the upper side to the mesh on the lower side as a cutting line.
(B) The trapezoidal middle net has an upper side <a lower side, and the inclined side forms the front surface of the basket. The front net of the long basket is inclined rearward along the slope of the trapezoid medium net. Basically, changes in the slope are handled by changing the aspect ratio of the mesh.However, they can be stacked in a stair-like manner, combined with a rectangular parallelepiped stone basket and an inclined type, or sloped on the laid ground. Correspond.
(C) Next, a trapezoidal mesh net is arranged at a predetermined position of the trunk net, and they are joined via a joining tool to form a stone filling space having an open top surface. After the stuffing of stones, the production of the long inclined basket is completed by attaching a lid net.
[0008]
[Technical Document 2] JP-A-2002-108570 Inclined Ishizume Basket
The following measures are taken for the linear connection of the long basket.
(A) The trapezoidal middle nets are arranged at predetermined intervals inward from the edges of both ends of the body net, and the overhangs are retained at both ends of the body knitting.
(B) In connecting the long inclined baskets, the edges of the opposed protruding portions are overlapped with each other and connected via a connecting tool. A single stone-filled space is formed in the connecting portion together with both overhanging portions. After the stuffing of stones, attaching the lid net completes the connection of the long basket.
(C) There is no longer any discrepancy in the joints or overlap in the middle net.
[0010]
The following measures will be taken with regard to the polygonal connection of long inclined baskets.
(A) In the broken-line type connection, a gap is formed between the bottom surfaces of the long inclined baskets that are connected to each other. Since the mesh is strong, the edge of the bottom surface of the long basket can be connected to any mesh of the bottom filling net, that is, at any angle.
(B) A connection net made of a tortoiseshell wire mesh is prepared to compensate for voids generated on the front and back surfaces. If the "torsion" of the column line is changed to "corner", it can be easily bent, and the width can be adjusted freely. Further, as shown in FIG. 8, the front connection network has a composite structure of two members, so that the shape can be changed.
(C) If the contact part of the long basket and the connecting net is connected via the connecting tool, a stone packing space is formed, and after the stone packing, the connection of the long basket is completed by attaching the lid net. .

Embodiments of the present invention will be described below with reference to the drawings.
[FIG. 1] is a plan view showing an example of a turtle shell wire mesh 2 for a long inclined basket according to the present invention. The specifications of the turtle wire mesh 2 of this example are as follows: the column wire 21 is a surface-treated steel wire, the wire diameter is 4 mm, and the mesh 3 is (interval of the left and right opposing torsion ) × (distance of the vertical angle opposing the upper and lower sides) = 80. × 100 mm. The turtle shell wire mesh 2 woven into a width of about 2m300 (= 80mm × 28.5 meshes) is unfolded on the site as it is long, and the folding curve 23 that sequentially passes through the “torsion” 22 is turned into a “corner” into a U shape. Bend. The length of the coiled wire mesh is up to 50 m depending on the machine, and is generally 8 m when cut and transported.
[0013]
FIG. 2 is a plan view showing the trapezoidal mesh net 2 for trapezoidal mesh according to the present invention. In this example, the wire mesh 2 forming the trapezoidal mesh 4 has the same specifications as in FIG. A diagonal line that passes through the meshes 31 adjacent to the oblique position from the mesh 3 on the upper side one by one and reaches the mesh 32 on the lower side is set as a cutting line 5 to form a trapezoidal inclined side. If the cutting line 5 passes through the rectangular central mesh 33 of the wire mesh 2, the two trapezoids formed by division are congruent and the production is efficient.
[0014]
FIG. 3 is a perspective view showing a mode of forming the trunk net 11 of the long basket 1 of the present invention. The turtle wire mesh 2 having the specifications shown in FIG. 1 is unfolded on the site as it is long, and the folding curve 23 is bent, and the "torsion" of the column line is changed to a "corner" to form a U-shaped cross section. In this example, the mesh 3 forms eight front nets 7, six and a half rear nets 8, and 16 bottom nets 9. Since the tortoise shell wire mesh 2 is large in rigidity at the 4 mm line 21, the bent shape is maintained. Since the trunk net 11 has an integral structure in the longitudinal direction, there is no longer any connection work between baskets, displacement, and overlap of the middle net, which appeared in the conventional futon cage.
[0015]
FIG. 4 is a perspective view showing an assembling mode of the long basket 1 of the present invention. The trapezoidal mesh net 4 shown in FIG. 2 is disposed at a predetermined position of the trunk net 11 at, for example, 1 m intervals, with the inclined side facing forward. Next, the edges of the trapezoidal middle net 4 are connected to the front net 7, the rear net 8 and the bottom net 9 via a connecting metal, for example, a spiral iron wire, whereby the assembly is completed, and a plurality of stone filling spaces 13 are formed. Since the front net 7 is connected to the inclined side of the trapezoidal middle net 4, it is characterized by being inclined rearward.
[0016]
[FIG. 5] is a perspective view showing a completed form of the long inclined basket 1 of the present invention. After completion of the stone filling in the stone filling space 13, if the lid net 10 is covered and connected to the upper edges of the front net 7 and the rear net 8 via the connecting tool 12, the production of the long inclined basket is completed.
[0017]
FIG. 6 is a perspective view showing a mode in which the long baskets 1, 1 of the present invention are linearly connected. At both ends of the trunk net 11, the trapezoidal mesh net 4 is disposed apart from the edge of the trunk net 11, the overhang portions 15, 15 are retained, and the edges are overlapped by about one stitch and joined. In the connecting portion, one overhanging portion 15, 15 is combined to form one stone filling space 13. After filling the stones, the lid net 10 is attached and the connection is completed. Thus, the efficiency of the connection work and the reduction of the construction cost are realized.
[0018]
FIG. 7 is a plan view showing a mode in which the long baskets 1, 1 of the present invention are connected in a polygonal line.
(B) A connecting net 6 of an appropriate size made of a tortoiseshell wire mesh 2 is laid in the gap between the long inclined baskets 1 and 1 arranged in a broken line, and the edges of the bottom nets 9 and 9 of the long inclined baskets 1 and 1 are It is connected to the connection network 6 via the connecting tool 12. Since the tortoise-mesh mesh 3 of the connecting net 6 is strong, it can be connected to any mesh. Therefore, the bottom nets 9 and 9 can be connected to broken lines in any direction.
(B) Next, if the gaps between the front and back surfaces of the connecting portions of the long inclined baskets 1 and 1 are complemented by connecting nets 61 and 62 of an appropriate size made of the wire mesh 2, the connecting portions become the clogging space 13 having an open upper surface. It becomes. After filling the stones, the lid net 10 is attached and the connection is completed.
[0019]
[FIG. 8] is an explanatory view showing another example of the front connection network 61 relating to the polygonal connection of the long inclined basket 1 of the present invention. In this example, the front connection network 61 is composed of two rectangular wire meshes 2 and 2, and is connected via the connection tool 12. The shape can be corrected to a trapezoid by the diagonal connection. Further, with respect to each of the wire meshes 2 and 2, if the "torsion" of the column line is changed to "corner", the wire can be easily bent, so that the width can be freely adjusted by bending the side edge. Thus, the front connection network 61 of this embodiment can be fitted in the front gap of the polygonal connection shown in FIG.
[0020]
According to the present invention, the use of the long inclined basket according to the present invention provides a further advantage of the slope-shaped stone-filled basket work, which has been originally evaluated from the viewpoint of landscape, structure, driftwood, vegetation, etc. Began to overlap. That is, the structural causes of the connection work between the baskets and the overlapping of the inner net, which appeared in the conventional "Futon cage" construction, and the "deviation" appearing at the connection place have been eliminated. Further, the development of the method of connecting long baskets according to the present invention supports the implementation of long baskets. It should be noted that the tortoise-shaped wire netting, which is a ground net of a long inclined basket, is much superior to the diamond-shaped wire netting in strength and flexibility. The long basket of the present invention has both the advantages of the slope shape and the long basket while maintaining the advantages of the ground net sufficiently.
