Description

【0001】
【発明の属する技術分野】
本発明は、継ぎ手および継ぎ手を用いてブロック間を契合して得られた地下設備の製造技術に属する。
【0002】
【従来の技術】
オス継ぎ手の凸状部をメス継ぎ手の凹部に挿入して契合する継ぎ手は、図8に示すように、オス継ぎ手の凸部外径とメス継ぎ手の凹部内径がほぼ同等となるように構成されている。 継ぎ手の材質が弾性体であるかあるいは塑性変形を生じるものである場合はオス継ぎ手の外径がわずかにメス継ぎ手の内径より大きくして確実に契合できるようにしている。しかし、この場合、オス継ぎ手の外周全体をあるいはメス継ぎ手の内周全体を変形させるため多大な力を要する。
【0003】
【発明が解決しようとする課題】
本発明は、小さな力で確実な契合を可能とする継ぎ手の提供と、かかる継ぎ手を用いてブロックを相互に契合させることで地下に水槽用の空間を確保し、あるいは軽量盛土の芯とした地下施設の構築方法を提案するものである。
【0004】
【課題を解決するための手段】
本第1の発明は、弾性変形性能を有し、オス継ぎ手の凸部が、メス継ぎ手の凹部に契合するオス、メス継ぎ手において、オス継ぎ手の凸部の周囲に襞部が設けられ、オス継ぎ手がメス継ぎ手と契合する際、前期襞部が契合部において弾性変形を起こすことにより契合を強化することを特徴とする継ぎ手であり、本第2の発明は、上記記載の継ぎ手を用い、ブロック間を契合することで地下に空間を形成して得られた地下施設である。
【0005】
【発明の実施の形態】
以下本発明を図を用いて、より詳細に説明する。
図1は、本発明に関わるオス継ぎ手の外形を示している。
【0006】
図1aに示すように、本発明のオス継ぎ手の外周辺には縦方向に薄い襞が設けられている。
オス継ぎ手のメス継ぎ手との契合部にあたる凸部の外径はメス継ぎ手の内径と同じあるいは襞の変形による厚み増加を考慮し少し小さめであってもよい。
しかし、凸部の襞を含めての外径は凹部の内径以上でなければならない。
必要に応じてオス継ぎ手の先端部にテーパを設け、ガイドとすることが好ましい。本継ぎ手の主用途である地下の雨水貯留槽、浸透槽あるいは軽量盛土の芯の用途に対しては、オス継ぎ手の外寸は、10〜20mmであり、襞の厚み、張り出し長さはそれぞれその先端で0.5〜2、1〜3mm程度が好ましい。張り出し長さはオス継ぎ手の付け根で先端部に対して1.2〜2.0倍程度となる。襞の厚み、張り出し長さは、オス継ぎ手の外寸、契合すべきブロックの大きさ、形状に合わせて変えることが好ましい。
また図1bに示すようにオス継ぎ手が縦方向に複数に櫛状に分割され、メス継ぎ手に挿入する際、櫛状に分割された間隙が狭まるようになっているものでもよい。
【0007】
図2は、本発明の継ぎ手が互に契合した状態を示す概念図である。継ぎ手の材質の弾性限界内にある場合を示しており、継ぎ手の契合部において襞は押しつぶされ、直接契合していない部分は襞が当初の状態を保っている。
図で明らかなように、契合部では継ぎ手間で契合部での襞が弾性変形あるいは塑性変形したことにより強く契合する。弾性変形している場合は、弾性変形による反力が作用する。また、変形が一部塑性変形となる場合であってもなんらさしさわりがない。
また、結合部の下方においては襞部が元の状態に戻り襞部が立つため契合状態がより確実になる。
【0008】
襞部は継ぎ手全体に較べ小さいため、契合状態に入るとき、襞部の変形を伴うがそれに要する力は小さくてすむ。
【0009】
図1では継ぎ手の凸部の外形状が円となっているが、円に限定されるものではなく多角形など適宜変えることができる。また、オス継ぎ手の形状がガイド部を除き上下とも同形として表されているが、先端部から付け根に向かって大きくなるようにテーパを設けた形状であってもよい。
【0010】
図3は、4個のブロックを上下方向あるいは左右方向に契合するための継ぎ手の一例を示している。
図4に示すように、図3の継ぎ手は、4個のブロック(例えば、図7a,bに示すようなブロックの上枠の4隅、あるいは図7c,dに示すブロックの盤体部の四隅)をつき合わせ、上枠あるいは盤体部の隅に設けたメス継ぎ手と契合させる。
図3の継ぎ手は限らず、下方にのみ凸部を有するものあるいは、凸部が直線状に2つ並んだものは、ブロックを並べたときその周辺部に配置されるブロック用に用いるなど、必要に応じて使い分けることができる。
【0011】
図5、図6は、図7に示すブロック類を上記継ぎ手で契合し、空間を構成し、地下に埋設あるいはその上部に土盛りした施設の概要を示している。
図5は、地下貯留槽であり、ブロックを上下左右に契合させ、その周囲を透水性あるいは遮水性のシートでおおい、ブロック部の空間を浸透槽、あるいは貯留槽とするものである。
【0012】
図7は、軟弱地盤上にブロックを組み上げその周囲を透水性シートで覆い、その周囲に土盛りし、その上部を公園、道路等として利用するものを示している。
【0013】
【発明の効果】
本発明は、上記説明の通り、オス継ぎ手の周囲に設けた襞による弾性あるいは塑性変形によって、契合部の契合強さを高めるとともに、契合部外の自由状体の襞部が継ぎ手の契合をはずすのを妨げるため、より確実な契合が得られる。
しかも、襞部が小さいため小さな力で契合できる。
上記継ぎ手を用いて契合組み立てされた地下施設は全体が一体となり、そのため施設にかかる力が全体に広がり、施設の強度が高まる。

BACKGROUND OF THE INVENTION
The present invention belongs to a manufacturing technique of an underground facility obtained by engaging a block with a joint using a joint.
[0002]
[Prior art]
As shown in FIG. 8, the joint that engages by inserting the convex portion of the male joint into the concave portion of the female joint is configured such that the convex outer diameter of the male joint and the concave inner diameter of the female joint are substantially equal. Yes. If the material of the joint is an elastic body or causes plastic deformation, the outer diameter of the male joint is slightly larger than the inner diameter of the female joint so as to ensure engagement. However, in this case, great force is required to deform the entire outer periphery of the male joint or the entire inner periphery of the female joint.
[0003]
[Problems to be solved by the invention]
The present invention provides a joint that enables a reliable engagement with a small force, and secures a space for the aquarium in the basement by mutually engaging the blocks with such a joint, or a base for a lightweight embankment. It proposes a construction method of facilities.
[0004]
[Means for Solving the Problems]
The first aspect of the present invention is a male and female joint having elastic deformation performance, wherein the convex part of the male joint engages with the concave part of the female joint, and a collar is provided around the convex part of the male joint. Is a joint that strengthens the engagement by causing elastic deformation at the engagement portion when the first rib is engaged with the female joint, and the second invention uses the joint described above, It is an underground facility obtained by forming a space in the basement by signing.
[0005]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, the present invention will be described in more detail with reference to the drawings.
FIG. 1 shows the external shape of a male joint according to the present invention.
[0006]
As shown in FIG. 1a, a thin ridge is provided in the vertical direction on the outer periphery of the male joint of the present invention.
The outer diameter of the convex portion corresponding to the engagement portion with the female joint of the male joint may be the same as the inner diameter of the female joint or may be slightly smaller in consideration of an increase in thickness due to deformation of the heel.
However, the outer diameter including the wrinkles of the convex portion must be greater than or equal to the inner diameter of the concave portion.
If necessary, it is preferable to provide a taper at the tip of the male joint to provide a guide. For underground rainwater storage tanks, seepage tanks or lightweight embankment cores, which are the main uses of this joint, the outer dimensions of the male joint are 10 to 20 mm, and the thickness of the ridge and the overhang length are respectively About 0.5-2 and 1-3 mm are preferable at the front-end | tip. The overhang length is about 1.2 to 2.0 times the tip of the male joint. It is preferable to change the thickness of the heel and the overhang length according to the outer dimensions of the male joint, the size and shape of the block to be engaged.
Also, as shown in FIG. 1b, the male joint may be divided into a plurality of combs in the vertical direction, and when inserted into the female joint, the gap divided into the combs may be narrowed.
[0007]
FIG. 2 is a conceptual diagram showing a state in which the joints of the present invention are engaged with each other. The case where it is within the elastic limit of the material of the joint is shown, and the heel is crushed at the joint portion of the joint, and the heel keeps the original state in the portion not directly engaged.
As is apparent from the figure, the engagement portion is strongly engaged by the elastic deformation or plastic deformation of the wrinkles at the engagement portion between the joints. In the case of elastic deformation, a reaction force due to elastic deformation acts. Even if the deformation is partly plastic deformation, there is no touch.
Moreover, since the collar part returns to the original state and the collar part stands under the coupling part, the engagement state becomes more reliable.
[0008]
Since the buttock is smaller than the entire joint, when entering the engagement state, the buttock is deformed but the force required for it is small.
[0009]
In FIG. 1, the outer shape of the convex portion of the joint is a circle, but the shape is not limited to a circle, and a polygon or the like can be appropriately changed. Moreover, although the shape of the male joint is expressed as the same shape at the top and bottom except for the guide portion, the shape may be such that a taper is provided so as to increase from the tip portion toward the root.
[0010]
FIG. 3 shows an example of a joint for engaging four blocks in the vertical direction or the horizontal direction.
As shown in FIG. 4, the joint of FIG. 3 has four blocks (for example, the four corners of the upper frame of the block as shown in FIGS. 7a and 7b, or the four corners of the block body of the block shown in FIGS. 7c and d). ) And engage with the female joint provided at the upper frame or the corner of the board.
The joints in FIG. 3 are not limited to those having convex portions only on the lower side or those having two convex portions arranged in a straight line, such as being used for blocks arranged in the periphery when blocks are arranged. It can be used properly according to.
[0011]
FIG. 5 and FIG. 6 show an outline of a facility in which the blocks shown in FIG. 7 are engaged with the above-described joints to form a space and are buried in the basement or buried in the upper part thereof.
FIG. 5 shows an underground storage tank in which a block is engaged vertically and horizontally, and its periphery is covered with a water-permeable or water-impervious sheet, and the space of the block portion is used as an infiltration tank or a storage tank.
[0012]
FIG. 7 shows a structure in which blocks are assembled on soft ground, the periphery is covered with a water-permeable sheet, the surroundings are piled up, and the upper part is used as a park, road, or the like.
[0013]
【The invention's effect】
As described above, the present invention increases the engagement strength of the engagement portion by the elasticity or plastic deformation caused by the heel provided around the male joint, and the flange portion of the free-form body outside the engagement portion releases the engagement of the joint. As a result, a more secure contract is obtained.
Moreover, since the buttock is small, it can be engaged with a small force.
The underground facilities that are contracted and assembled using the above joints are united, so that the force applied to the facilities spreads throughout and the strength of the facilities increases.
