Description

本発明は、雨水貯留浸透施設用組立体、及び、これを用いた雨水貯留浸透施設に関する。   The present invention relates to an assembly for a rainwater storage and penetration facility, and a rainwater storage and penetration facility using the same.

雨水貯留浸透施設について、従来より種々のタイプのものが提案され、実用に供されている。例えば、特許文献１に開示されている雨水貯留浸透施設は、構造体を有している。特許文献１記載の構造体は、複数の枠状部材を、地下貯水空間の容量を画定する内壁に沿って六面体状に組み合わせたものでなり、内壁の崩壊を防止するために、地下貯水空間に埋設される。   Various types of rainwater storage and penetration facilities have been proposed and put into practical use. For example, the rainwater storage and penetration facility disclosed in Patent Document 1 has a structure. The structure described in Patent Document 1 is a combination of a plurality of frame-like members in a hexahedron shape along the inner wall that defines the capacity of the underground water storage space. In order to prevent the inner wall from collapsing, Buried.

ところで、この種の雨水貯留浸透施設には、一般住宅向けの小容量なものから、商業施設向けの大容量なものまで幅広い需要が存在し、需要に応じて地下貯水空間の具体的な容量が決定される。特に、大容量の雨水貯留浸透施設を設置する場合、予め決定された地下貯水空間の高さ寸法に追従して、複数の構造体を高さ方向に積み重ねる必要が生じる。従って、この種の構造体、及び、構造体を積み重ねて形成される組立体には、土圧等の押圧力や、上載荷重に十分耐えうる構造的一体性を有していることが求められる。   By the way, this kind of rainwater storage and infiltration facilities has a wide range of demands ranging from small capacity for general housing to large capacity for commercial facilities. The specific capacity of underground water storage space depends on the demand. It is determined. In particular, when installing a large-capacity rainwater storage and penetration facility, it is necessary to stack a plurality of structures in the height direction following the predetermined height dimension of the underground water storage space. Therefore, this type of structure and an assembly formed by stacking the structures are required to have structural integrity that can sufficiently withstand pressing force such as earth pressure and an overload. .

また、構造体を積み重ねて組立体を構成する場合、積層数に比例して構成部材数が増えるから、組立作業を効率的に行いうることが求められる。さらに、構造体を積み重ねて組立体を構成する場合、基礎となる下層側の構造体上で、上層側の構造体の組立作業を行うこととなるから、組立作業を安全に行いうることが求められる。   Further, in the case of constructing an assembly by stacking structures, the number of constituent members increases in proportion to the number of layers, so that it is required that the assembly work can be performed efficiently. In addition, when constructing an assembly by stacking structures, the assembly work of the upper layer side structure is performed on the lower layer side structure which is the foundation, and therefore it is required that the assembly work can be performed safely. It is done.

しかし、特許文献１記載の発明では、上述した何れの要請に対しても充分に応えることができない。例えば、特許文献１の図１５では、複数の枠状部材により構成される構造体を、高さ方向に直接積み重ねて組立体を構成しているから、構造的一体性の面で改善の余地が認められる。   However, the invention described in Patent Document 1 cannot sufficiently satisfy any of the above-mentioned requests. For example, in FIG. 15 of Patent Document 1, a structure constituted by a plurality of frame-like members is directly stacked in the height direction to form an assembly, so there is room for improvement in terms of structural integrity. Is recognized.

また、特許文献１では、枠状部材、又は、複数の枠状部材により構成される構造体を、高さ方向に直接積み重ねて組立体を構成しているから、作業員は、足場の悪い下層側の構造体上で、上層側の構造体の組立作業を行うこととなる。従って、組立作業の効率性、及び、安全性確保の観点から改善の余地が認められる。   Moreover, in patent document 1, since the structure comprised from a frame-shaped member or a some frame-shaped member is directly piled up in the height direction, and an assembly is comprised, a worker is a lower layer with a bad scaffold. The assembly work of the upper layer side structure is performed on the side structure. Therefore, there is room for improvement from the viewpoint of ensuring the efficiency of assembly work and ensuring safety.

面板部１１２０は、平板状であって、板面の大部分が閉じており、一面の側の空間と、他面の側の空間とを仕切ることができる。面板部１１２０は、板面が長方形形状であって、板面の幅方向Ｗで相対向する２辺１１２２、１１２３と、幅方向Ｗに交差する高さ方向Ｈで相対向する２辺１１２４、１１２５とを有している。   The face plate portion 1120 has a flat plate shape, and most of the plate surface is closed, and can partition a space on one side and a space on the other side. The face plate portion 1120 has a rectangular plate surface, and two sides 1122 and 1123 facing each other in the width direction W of the plate surface, and two sides 1124 and 1125 facing each other in the height direction H intersecting the width direction W.

The ribs 1121 extend along the width direction W and the height direction H in the plane of one surface and the other surface and intersect in a lattice pattern.

通水孔１３は、リブ１１２１によって格子状に区画された領域内において、面板部１１２０を厚み方向Ｌに貫通している。通水孔１３は、第１の構造体１０ａが雨水貯留施設に用いられる場合には、設けないこともできる。   The water passage hole 13 penetrates the face plate portion 1120 in the thickness direction L in a region partitioned by the ribs 1121 in a lattice shape. The water passage hole 13 can be omitted when the first structure 10a is used in a rainwater storage facility.

図５の第２の構成部材１１２のもう一つの特徴は、幅方向Ｗに向かい合う２辺１１２２、１１２３に、それぞれ凹状嵌合部１４、凸状嵌合部１５を有している点にある。凹状嵌合部１４は、辺１１２３において、辺１１２３の端面から幅方向Ｗに後退した位置に形成され、面板部１１２０の一面及び他面を、高さ方向Ｈに沿って条状に連続して伸びている。凸状嵌合部１５は、辺１１２２において、辺１１２２の端面から幅方向Ｗに後退した位置に形成され、高さ方向Ｈに沿って連続して伸びている。この構成によると、図４の第１の構成部材１１１のみを用いて組み合わせたときに生じる隙間に対して第２の構成部材１１２を取り付けることにより、前記隙間を第２の構成部材１１２で塞ぐことができる。   Another feature of the second component member 112 in FIG. 5 is that a concave fitting portion 14 and a convex fitting portion 15 are provided on two sides 1122 and 1123 facing in the width direction W, respectively. The concave fitting portion 14 is formed at a position in the side 1123 that is retreated in the width direction W from the end surface of the side 1123, and one surface and the other surface of the face plate portion 1120 are continuously formed in a strip shape along the height direction H. It is growing. The convex fitting portion 15 is formed at a position retracted in the width direction W from the end surface of the side 1122 on the side 1122 and continuously extends along the height direction H. According to this configuration, the second structural member 112 is attached to the gap that is generated when the first structural member 111 of FIG. 4 is used alone, thereby closing the gap with the second structural member 112.

It is continuously growing.

貫通部１２１７は、外枠部１２１０の内部領域を構成する貫通部分が、凹状嵌合部１４と、内枠部１２１６によって、格子状に４分割されて形成されている。貫通部１２１７は、部材の軽量化、及び、製造コストの低減を図るとともに、第３の構成部材１２１が雨水貯留浸透施設に用いられた場合に、貯留された雨水の流動性を向上させる。   The penetrating portion 1217 is formed by dividing a penetrating portion constituting the inner region of the outer frame portion 1210 into a lattice shape by a concave fitting portion 14 and an inner frame portion 1216.

The substrate portion 31 of FIG. 11 has a concave portion and a convex portion corresponding to each other on two sides facing each other in the width direction W of the plate surface and two sides facing each other in the vertical direction L of the plate surface. The so-called “Hatoo joint” can be constructed.

基板部３１は、内板３２と、リブ３３とによって構成されており、内板３２の板面に対してリブ３３が垂直に突設された構造を有している。   The substrate part 31 is constituted by an inner plate 32 and ribs 33, and has a structure in which the ribs 33 project vertically from the plate surface of the inner plate 32.

凸部３５は、第２の開口部１７に差込可能な平面形状、及び、外周形状を有し、第１の開口部１６に向かい合う基板部３１の他面において、複数の第２の開口部１７に対応する位置に突設されている。   The convex portion 35 has a planar shape that can be inserted into the second opening portion 17 and an outer peripheral shape, and a plurality of second opening portions on the other surface of the substrate portion 31 facing the first opening portion 16. It protrudes at a position corresponding to 17.

図１及び図２の組立体における、図９及び図１０の中間板２０と、図１１の蓋板３０の結合構造について、図１２を参照して説明する。第１、第２の構造体１０ａ、１０ｂは、互いの第１の開口部１６が中間板２０を介して向かい合う関係で積層され、積層された状
態で凸部２５が第２の開口部１７に差し込まれ、且、凹溝部２６に仕切り部１２の端縁が嵌合されている。第２の開口部１７に凸部２５が差し込まれ、凹溝部２６に、仕切り部１２の端縁が嵌合されことにより、組立体の構造的一体性が向上する。違う言葉で表現すれば、複数の第２の開口部１７に対して、中間板２０に一体的に形成された複数の凸部２５を差し込むことにより、中間板２０によって、例えば構造体１０ａの開口端面が固定されるから、組立体の構造的一体性が向上する。中間板２０は、構造体の積層数、すなわち高さ方向Ｈに向かい合う構造体相互の連結部分が増えれば、その分だけ設置が増加する。 A coupling structure of the intermediate plate 20 of FIGS. 9 and 10 and the cover plate 30 of FIG. 11 in the assembly of FIGS. 1 and 2 will be described with reference to FIG. The first and second structures 10a and 10b are stacked such that the first openings 16 face each other through the intermediate plate 20, and the protrusions 25 are formed on the second openings 17 in the stacked state. The end edge of the partition portion 12 is fitted into the recessed groove portion 26. The convex portion 25 is inserted into the second opening portion 17 and the edge of the partition portion 12 is fitted into the concave groove portion 26, so that the structural integrity of the assembly is improved. In other words, by inserting a plurality of convex portions 25 formed integrally with the intermediate plate 20 into the plurality of second openings 17, the intermediate plate 20 allows, for example, opening of the structure 10a. Since the end faces are fixed, the structural integrity of the assembly is improved. If the number of structures stacked, that is, the number of connecting portions between structures facing each other in the height direction H is increased, the intermediate plate 20 is installed correspondingly.

蓋板３０は、第２の構造体１０ｂにおいて、上側の第１の開口部１６に取り付けられ、取り付けられた状態で、凸部３５が第２の開口部１７に差し込まれ、且、凹溝部３６に仕切り部１２の端縁が嵌合されている。従って、第２の開口部１７に凸部３５が差し込まれ、凹溝部３６に、仕切り部１２の端縁が嵌合されことにより、組立体の構造的一体性が向上する。   The cover plate 30 is attached to the upper first opening 16 in the second structure 10b, and in the attached state, the convex portion 35 is inserted into the second opening 17 and the concave groove portion 36 is attached. The end edge of the partition part 12 is fitted to this. Therefore, the convex portion 35 is inserted into the second opening portion 17 and the edge of the partition portion 12 is fitted into the concave groove portion 36, thereby improving the structural integrity of the assembly.

図１２の組立体の構造によると、第１、第２の構造体１０ａ、１０ｂの第１の開口部１６に、それぞれ中間板２０、蓋板３０を凹凸嵌合させるだけでよいから、組立作業が極めて容易になる。しかも、上述した組立構造は、第１〜第４の構成部材１１１〜１２２の第２の開口部１７と、中間板２０の内部構造たる凸部２５、及び、蓋板３０の内部構造たる凸部３５との組み合わせによって行われ、特殊な連結器具を用いる必要がないから組立効率を向上することができる。   According to the assembly structure shown in FIG. 12, the intermediate plate 20 and the cover plate 30 need only be concavo-convexly fitted into the first openings 16 of the first and second structures 10a and 10b. Is extremely easy. Moreover, the assembly structure described above includes the second opening 17 of the first to fourth constituent members 111 to 122, the convex portion 25 that is the internal structure of the intermediate plate 20, and the convex portion that is the internal structure of the lid plate 30. As a result, the assembly efficiency can be improved.

図１乃至図１２を参照して説明したように、第１、第２の構造体１０ａ、１０ｂは、第１〜第４の構成部材１１１〜１２２によって組み立てられている。この結合は、第１〜第４の構成部材１１１〜１２２の内部構造たる凹状、凸状嵌合部１４、１５の組み合わせによって行われ、特殊な連結器具を用いる必要がないから組立効率を向上することができる。   As described with reference to FIGS. 1 to 12, the first and second structures 10 a and 10 b are assembled by the first to fourth component members 111 to 122. This coupling is performed by a combination of the concave and convex fitting portions 14 and 15 which are the internal structures of the first to fourth constituent members 111 to 122, and it is not necessary to use a special connecting device, thereby improving the assembly efficiency. be able to.

また、第１、第２の構造体１０ａ、１０ｂは、第１〜第４の構成部材１１１〜１２２の端部を結合することにより構成されているから、様々な施工条件に追従した側壁部１１を形成することができる。   Moreover, since the 1st, 2nd structure 10a, 10b is comprised by couple | bonding the edge part of the 1st-4th structural members 111-122, the side wall part 11 which followed various construction conditions Can be formed.

第１、第２の構成部材１１１、１１２は、それぞれ軽量であって、取り扱いが容易な平板状であるから、組立作業に大型の建設機械等を用いる必要が無い。従って、組立効率を向上することができる。   Each of the first and second constituent members 111 and 112 is a flat plate shape that is lightweight and easy to handle, so there is no need to use a large construction machine or the like for the assembly work. Therefore, assembly efficiency can be improved.

第１、第２の構成部材１１１、１１２は、板面の大部分が閉じているから、第１、第２の構成部材１１１、１１２を筒状に組み合わせることにより、内部空間１００を画定する側壁部１１を形成することができる。   Since most of the plate surfaces of the first and second constituent members 111 and 112 are closed, the side walls that define the internal space 100 are formed by combining the first and second constituent members 111 and 112 in a cylindrical shape. The part 11 can be formed.

側壁部１１は、第１、第２の構成部材１１１、１１２の組み合わせによって構成されている。しかも、側壁部１１を内側から支持する第３、第４の構成部材１２１、１２２は枠状であるから、内部空間１００の容量を最大限確保することができる。   The side wall portion 11 is configured by a combination of first and second constituent members 111 and 112. Moreover, since the third and fourth constituent members 121 and 122 that support the side wall portion 11 from the inside are frame-shaped, the capacity of the internal space 100 can be ensured to the maximum.

図１３は本発明の一実施形態に係る雨水貯留浸透施設について一部を破断して示す正面断面図である。図１３の雨水貯留浸透施設は、雨水浸透施設であって、組立体１と、点検口部材７と、設置穴５と、保護層６とを含む。ＧＬは地表面を示す。   FIG. 13 is a front cross-sectional view showing a part of the rainwater storage and infiltration facility according to one embodiment of the present invention. The rainwater storage and penetration facility in FIG. 13 is a rainwater penetration facility and includes an assembly 1, an inspection port member 7, an installation hole 5, and a protective layer 6. GL indicates the ground surface.

組立体１は、図１乃至図１２を参照して説明したものでなり、設置穴５の内部であって、地下に埋設されている。蓋板３０は、予め所定の箇所に点検のための設置孔が開設されている。点検口部材７は、高さ方向Ｈの一端が蓋板３０に載置され、他端が地表面ＧＬに
配置されている。 The assembly 1 is described with reference to FIGS. 1 to 12, and is embedded in the installation hole 5 and underground. The lid plate 30 is previously provided with an installation hole for inspection at a predetermined location. The inspection port member 7 has one end in the height direction H placed on the lid plate 30 and the other end placed on the ground surface GL.

保護層６は、設置穴５の内壁面５１と、組立体１の外周面との間に設けられる。保護層６は、不織布等の透水構造を有し、組立体１の内部に土砂や塵埃など異物混入を防止すると共に、組立体１の内部に貯留した雨水を地中に分散浸透させるための排出路として用いられる。もっとも、保護層６は、雨水貯留浸透施設の役割に応じて構造、及び、機能を設定することができる。例えば、雨水貯留浸透施設が貯留施設である場合、保護層６は、合成樹脂材料を主成分とするシート材であって、好ましくはゴムシートを用いた遮水層にかえられる。これは、雨水の貯留を主目的としていることに起因する。   The protective layer 6 is provided between the inner wall surface 51 of the installation hole 5 and the outer peripheral surface of the assembly 1. The protective layer 6 has a water-permeable structure such as a nonwoven fabric, and prevents foreign matter such as earth and sand and dust from entering the assembly 1 and discharges the rainwater stored in the assembly 1 to disperse and penetrate into the ground. Used as a road. But the protective layer 6 can set a structure and a function according to the role of a rainwater storage penetration facility. For example, when the rainwater storage and penetration facility is a storage facility, the protective layer 6 is a sheet material mainly composed of a synthetic resin material, and is preferably replaced with a water shielding layer using a rubber sheet. This is because the main purpose is to store rainwater.

図１３の雨水貯留浸透施設は、図１乃至図１２の組立体１を含むから、図１乃至図１２を参照して説明した組立体１の利点を全て有することができる。例えば、図１３の雨水貯留浸透施設を構成する組立体１において、第１、第２の構造体１０ａ、１０ｂの内部空間１００は、側壁部１１により画定されているから、地下に埋設された場合に、内部空間１００を、空間効率率の高い地下貯水空間５０として用いることができる。   Since the rainwater storage and infiltration facility of FIG. 13 includes the assembly 1 of FIGS. 1 to 12, it can have all the advantages of the assembly 1 described with reference to FIGS. For example, in the assembly 1 constituting the rainwater storage and infiltration facility of FIG. 13, the internal space 100 of the first and second structures 10 a and 10 b is defined by the side wall portion 11, so that it is buried underground. Moreover, the internal space 100 can be used as the underground water storage space 50 with a high space efficiency.

仕切り部１２は、内部空間１００において、向かい合う側壁部１１に結合されている。この構造によると、側壁部１１は、仕切り部１２によって内部から支持されているから、地下に埋設された場合に、内壁５１から加えられる土圧等の押圧力や、地表面ＧＬや、第１、第２の構造体１０ａ、１０ｂ相互の上載荷重に十分耐えうる構造的一体性を有することができる。   The partition portion 12 is coupled to the side wall portions 11 facing each other in the internal space 100. According to this structure, since the side wall part 11 is supported from the inside by the partition part 12, when buried in the basement, the pressing force such as earth pressure applied from the inner wall 51, the ground surface GL, the first surface The second structural bodies 10a and 10b can have structural integrity that can sufficiently withstand the mounting load between the second structural bodies 10a and 10b.

第１の開口部１６は、中間板２０によって覆われている。この構造によると、例えば、組立体１の組立作業時に、基礎となる下層側の第１の構造体１０ａの第１の開口部１６が、中間板２０で覆われているから、作業員は、中間板２０上を歩きながら上層側の第２の構造体１０ｂの組立作業を行うことができる。従って、組立作業の効率を向上し、且、安全性を確保することができる。   The first opening 16 is covered with the intermediate plate 20. According to this structure, for example, during assembly work of the assembly 1, the first opening 16 of the first structure 10 a on the lower layer side serving as a foundation is covered with the intermediate plate 20. While walking on the intermediate plate 20, the assembly work of the second structure 10b on the upper layer side can be performed. Therefore, the efficiency of assembly work can be improved and safety can be ensured.

第１、第２の構造体１０ａ、１０ｂは、中間板２０を介して第１の開口部１６が向かい合う関係で積層され、積層された状態で凸部２５が第２の開口部１７に嵌合され、且、仕切り部１２の端縁が凹溝部２６に案内されている。この構造によると、構造体に対する中間板２０の位置決めが容易になり、組立作業を効率的に行うことができる。   The first and second structures 10a and 10b are stacked with the first opening 16 facing each other via the intermediate plate 20, and the convex portion 25 is fitted to the second opening 17 in the stacked state. In addition, the edge of the partition portion 12 is guided to the concave groove portion 26. According to this structure, the intermediate plate 20 can be easily positioned with respect to the structure, and the assembly work can be performed efficiently.

また、第２の開口部１７に凸部２５が嵌合されることにより、組立体１の揺動が防止され、構造的一体性が向上する。しかも、１つの中間板２０に突設された複数の凸部２５が、複数の第２の開口部１７に嵌合されるとともに、仕切り部１２の端縁が凹溝部２６に案内されているから、中間板２０と第１、第２の構造体１０ａ、１０ｂとの構造的一体性が向上する。   Further, by fitting the convex portion 25 into the second opening portion 17, the assembly 1 is prevented from swinging and the structural integrity is improved. Moreover, the plurality of convex portions 25 projecting from one intermediate plate 20 are fitted into the plurality of second openings 17 and the edge of the partition portion 12 is guided to the concave groove portion 26. The structural integrity of the intermediate plate 20 and the first and second structures 10a and 10b is improved.

In the plurality of intermediate plates 20, the intermediate plate 20 b in FIG. 18 is disposed at a place where the inspection port member 7 is placed. The intermediate plate 20b in FIG. 18 has the same configuration as the intermediate plate 20 in FIGS. 9 and 10 except that the inspection plate 28 is provided. The inspection hole 28 is disposed at a position overlapping the opening edge of the second opening 17 within the surface of the substrate portion 21, and penetrates the substrate portion 21 from one surface to the other surface.
