Description

【0001】
【発明の属する技術分野】
本発明は、歩道と車道の境界に設置した側溝の開口に装着し、歩道と車道の境界を形成する歩車道境界蓋ブロックを成形する型枠に関する。
【0002】
【従来の技術】
図11〜13は従来の歩車道境界蓋ブロック40、40’に関する。図11の歩車道境界蓋ブロック40は、板状の蓋部41と、蓋部41上面から長さ方向に沿って立設した境界部42とで断面が概略逆T字形に形成されている。両端には集水切欠43が形成されている。図12の歩車道境界蓋ブロック40’は歩車道境界の始点又は終点に用いるもので、境界部42’の一端が斜面部42aとなっている点が歩車道境界蓋ブロック40と異なり、他端に集水切欠43が形成されている。歩車道境界蓋ブロック40、40’は、図13に示すように、側溝Uの開口を塞ぐように側溝Uに被せられる。側溝Uの左右の一側が歩道、他側が車道となっている。
【0003】
従来、歩車道境界蓋ブロックを用いる場合は側溝内の清掃などのために管理桝を設けるのが一般的である。管理桝50は側溝Uの間に適宜間隔で設けられる桝で、図14、15に示すように、側溝Uよりもやや深く形成され、上面にはグレーチング52が装着され、埋込ナット54が植設されている。また、境界部51がボルト53によって固定されている。桝内を清掃する場合は、ボルト53を外して境界部51及びグレーチング52を取り除く。
【0004】
図16は側溝U、歩車道境界蓋ブロック40、41、管理桝50の施工状態を説明する側面図である。同図に示すように、歩車道境界の端部には歩車道境界蓋ブロック40’が設置され、中間部には歩車道境界蓋ブロック40が設置される。管理桝50は、適宜間隔で側溝Uの間に設けられる。歩車道境界蓋ブロック40、40’の端部には集水切欠43が設けられているので、隣り合うブロックの集水切欠43が合わさって集水孔が形成される。
【0005】
【発明が解決しようとする課題】
従来の歩車道境界蓋ブロックは端部に集水切欠が設けられていたので集水孔はブロックの継ぎ目に形成されるのみであった。このため、集水孔の数が制限され、路面に水たまりが生じることが多いという問題があった。また、管理桝を設置しなければならないので施工が煩雑であり、管理桝の清掃の際にはボルトによって境界部を着脱しなければならないので作業が煩雑であり、また、ボルト及び埋込ナットの腐食、螺条へのゴミ詰まりなどの問題もあった。
【0006】
本発明は、集水孔を任意の間隔で任意の数だけ設けることを可能とし、道路面の水たまりの発生を防ぐと共に、管理桝の設置を不要とし、また、側溝の清掃作業を容易に行えるような歩車道境界蓋ブロックを成形する型枠を提供することを課題としてなされたものである。
【0007】
【課題を解決するための手段】
本発明は、板状の蓋部と、蓋部上面から長さ方向に沿って立設した境界部とで断面が概略逆T字形に形成され、その長さ方向の中間部に、前記境界部を水平方向に貫通する横孔と、該横孔に連通し前記蓋部を縦方向に貫通する縦孔とからなる集水孔が形成されている歩車道境界蓋ブロックを成形する型枠である。
【0008】
本発明の型枠によって成型されるブロックは、集水孔がブロックの長さ方向の中間部に設けられるので、任意の位置に任意の数だけ集水孔を設けることができる。集水孔は、境界部を水平方向に貫通する横孔と、該横孔に連通し前記蓋部を縦方向に貫通する縦孔とからなるが、横孔は中央部が最も断面積が小さく、両側にいくにしたがって次第に断面積が大きくなるテーパ孔とし、前記縦孔は上部が最も面積が小さく、下部にいくにしたがって次第に断面積が大きくなるテーパ孔となっている。このようにすることによって、以下に示す本発明の型枠によって容易にこの歩車道境界蓋ブロックを製造することができる。
【0009】
本発明の型枠は、薄い箱状の蓋成形部とその底部が深くなるように形成された境界成形部によってキャビティーがT字形をなす外枠と、一端が面積の小さい小端面、他端が面積の大きな大端面となっているテーパ筒状の2個の半体の小端面どうしを互いに接合分離自在に接合し、前記境界成形部の最上部に配設される、前記横孔を成形する横孔中子と、該横孔中子の上面に接合分離自在に接合し、下部が面積の小さな小端面上部が面積の大きな大端面となっている、前記縦孔を成形するテーパ筒状の縦孔中子とを有することを特徴とする歩車道境界蓋ブロックの型枠である。
【0010】
横孔中子の半体及び縦孔中子がテーパ筒状となっているので、これらのテーパが、いわゆる抜き勾配となり、硬化したコンクリートから中子を容易に抜き取ることができる。
【0011】
例えば、半体の一方の小端面に突起を、他方の小端面に凹部を形成し、該突起が該凹部に係合、分離するようにすれば、該2個の半体の小端面どうしを互いに接合分離自在に接合することができる。
【0012】
また例えば、縦孔中子の下面に突起を、横孔中子の上面に凹部を形成し、該突起が該凹部に係合、分離するようにすれば、縦孔中子を横孔中子の上面に接合分離自在に接合することができる。
【0013】
本発明の歩車道境界蓋ブロックの縦孔にグレーチングを着脱自在に装着すると、グレーチングを着脱するのみで、側溝内の清掃を行うことができる。
【0014】
【発明の実施の形態】
以下、実施例を表した図面に基づいて本発明を詳細に説明する。図1は歩車道境界蓋ブロック1の側面図、図2は底面図、図3は歩車道境界蓋ブロック1’の側面図、図4は図1のAA線断面及び図3のBB線断面図、図5は歩車道境界蓋ブロック10の平面図、図6は図5におけるCC線断面図、図7は側溝U内の清掃の説明図、図8は中子24、29の斜視図、図9は実施例の型枠20の断面図、図10は中子の脱型の説明図である。
【0015】
図1、2、4に示す歩車道境界蓋ブロック1は、板状の蓋部2と、蓋部2の上面から長さ方向に沿って立設した境界部3とで断面が概略逆T字形に形成され、その長さ方向の中間部2カ所に集水孔4が形成されている。集水孔4は、境界部3を水平方向に貫通する横孔5と、横孔5に連通し蓋部2を縦方向に貫通する縦孔6とからなる。図4に示すごとく、横孔5は中央部が最も断面積が小さく、両側にいくにしたがって次第に断面積が大きくなるテーパ孔であり、縦孔6は上部が最も面積が小さく、下部にいくにしたがって次第に断面積が大きくなるテーパ孔となっている。
【0016】
図3、4に示す歩車道境界蓋ブロック1’は、歩車道境界の端部に使用するもので、境界部3’の一端側が斜面部1aとなっている他は上述の歩車道境界蓋ブロック1と同じである。
【0017】
図5〜7に示す歩車道境界蓋ブロック10は、板状の蓋部11と、蓋部11の上面から長さ方向に沿って立設した境界部12とで断面が概略逆T字形に形成され、その長さ方向のほぼ中央に集水孔が形成されている。集水孔は、境界部12を水平方向に貫通する横孔15と、横孔15に連通し蓋部11を縦方向に貫通する縦孔16とからなる。縦孔16には段部17が形成され、ここにグレーチング13が載置、装着されている。横孔15は一方が大きく開口したテーパ孔となっており、この大きな開口からグレーチングを容易に着脱でき、また、図7に示すように、清掃ホース18を側溝内に差し込んでバキュームでゴミを吸い出し、容易に清掃することができる。歩車道境界蓋ブロック10を所々に配置することで、管理桝の設置が不要となる。
【0018】
歩車道境界蓋ブロック1は、図8〜10に示す型枠20によって容易に製造することができる。図9に示す型枠20は、歩車道境界蓋ブロック1を上下逆転状態で成形する型枠であって、薄い箱状の蓋成形部22と、その底部が深くなるように形成された境界成形部23によってキャビティー34がT字形をなす外枠21を有する。このような外枠は、従来の歩車道境界蓋ブロックを成形する際の周知の外枠を用いることができる。また、製品の脱型を容易にするために一部に開閉機構を設けることも可能である。
【0019】
本発明の型枠の特徴は中子にある。中子は横孔5を成形する横孔中子24と縦孔6を成形する縦孔中子29からなる。横孔中子24は、一端が面積の小さい小端面26、他端が面積の大きな大端面27となっているテーパ筒状の2個の半体25の小端面26どうしを互いに接合分離自在に接合したものである。2個の半体25は、一方の小端面に突起28が、他方の小端面に凹部(穴)が形成され、突起28が凹部に係合し、また分離することで小端面どうしを互いに接合または分離することができるようになっている。横孔中子24は境界成形部23の最上部にセットされる。縦孔中子29は横孔中子24の上面に接合分離自在に接合される。縦孔中子29の下面には突起32が、横孔中子24の上面には凹部(穴)が設けられ、突起32が凹部に係合し、または分離することで縦孔中子29を横孔中子24の上面に接合または分離できるようになっている。縦孔中子29は下部が面積の小さな小端面30に、上部が面積の大きな大端面31となっているテーパ筒状をなしている。
【0020】
図9の型枠20のキャビティー34にコンクリートを充填し、硬化後外枠21を脱型する。その状態が図10である。図10の状態から先ず、縦孔中子29上面に設けられる把手33をもってこれを上方(矢印D方向)に引き上げる。すると、突起32が横孔中子24上面の凹部から外れて縦孔中子29がブロック1から脱型される。次に、横孔中子24の各半体25を矢印E方向に引き出し、横孔中子24をブロック1から脱型する。横孔中子24の脱型は、縦孔中子を脱型した後の縦孔6にバールなどの治具を挿入してこじってもよいし、大端面27にフックなどを形成しておき、これを引っ張るなどしてもよい。横孔中子24の各半体25及び縦孔中子29は共にテーパ筒状をなし、抜き勾配を有しているので、容易に脱型することができる。なお、外枠21の脱型に先立って縦孔中子29を脱型しても差し支えない。
【0021】
【発明の効果】
本発明の歩車道境界蓋ブロックは、集水孔がブロックの長さ方向の中間部に設けられるので、任意の位置に任意の数だけ集水孔を設けることができ、したがって道路面に水たまりが発生するのを防止できる。また、縦孔にグレーチングを着脱自在に装着した歩車道境界蓋ブロックは側溝内の清掃を容易に行うことができ、管理桝を設置する必要もない。さらに本発明の型枠は、本発明の歩車道境界蓋ブロックを容易に製造でき、中子も容易に脱型することができる。

BACKGROUND OF THE INVENTION
The present invention relates to a mold for mounting a pedestrian road boundary lid block that is attached to an opening of a side groove installed at a boundary between a sidewalk and a roadway and forms a boundary between the sidewalk and the roadway.
[0002]
[Prior art]
FIGS. 11-13 relate to conventional pedestrian boundary lid blocks 40, 40 ′. The pedestrian road boundary lid block 40 of FIG. 11 has a plate-shaped lid portion 41 and a boundary portion 42 erected along the length direction from the upper surface of the lid portion 41 so that the cross section is formed in an approximately inverted T shape. Water collecting notches 43 are formed at both ends. The pedestrian road boundary lid block 40 ′ in FIG. 12 is used as a starting point or an end point of the pedestrian road boundary, and is different from the pedestrian road boundary lid block 40 in that one end of the boundary portion 42 ′ is a slope 42 a. A water collecting notch 43 is formed on the surface. As shown in FIG. 13, the pedestrian road boundary lid blocks 40, 40 ′ are placed on the side grooves U so as to close the openings of the side grooves U. One side of the gutter U is a sidewalk and the other side is a roadway.
[0003]
Conventionally, when a pedestrian road boundary lid block is used, a management rod is generally provided for cleaning the side groove. The control rods 50 are provided at appropriate intervals between the side grooves U, and are formed slightly deeper than the side grooves U as shown in FIGS. 14 and 15. A grating 52 is attached to the upper surface, and the embedded nut 54 is planted. It is installed. Further, the boundary portion 51 is fixed by a bolt 53. When cleaning the inside of the bag, the bolt 53 is removed and the boundary 51 and the grating 52 are removed.
[0004]
FIG. 16 is a side view for explaining a construction state of the lateral groove U, the walking road boundary lid blocks 40 and 41, and the management rod 50. As shown in the figure, a walking road boundary lid block 40 'is installed at the end of the walking road boundary, and a walking road boundary lid block 40 is installed in the middle. The management rods 50 are provided between the side grooves U at appropriate intervals. Since the water collecting notches 43 are provided at the ends of the pedestrian road boundary lid blocks 40 and 40 ', the water collecting notches 43 of adjacent blocks are combined to form a water collecting hole.
[0005]
[Problems to be solved by the invention]
Since the conventional pedestrian road boundary lid block has a water collection notch at the end, the water collection hole is only formed at the joint of the block. For this reason, there has been a problem that the number of water collecting holes is limited and a puddle is often generated on the road surface. In addition, the construction of the control rod is complicated, and the construction is complicated. When the management rod is cleaned, the boundary must be attached and detached with bolts, and the work is complicated. There were also problems such as corrosion and clogging of the threads.
[0006]
The present invention makes it possible to provide an arbitrary number of water collecting holes at arbitrary intervals, prevent the occurrence of puddles on the road surface, eliminate the need for installation of a management rod, and facilitate the cleaning work of the side grooves. An object of the present invention is to provide a mold for forming such a pedestrian road boundary lid block.
[0007]
[Means for Solving the Problems]
In the present invention, the plate-shaped lid portion and the boundary portion erected along the length direction from the upper surface of the lid portion are formed in a substantially inverted T shape in cross section, and the boundary portion is formed in the middle portion in the length direction. Is a mold for forming a pedestrian road boundary lid block in which a water collecting hole is formed which includes a horizontal hole penetrating in the horizontal direction and a vertical hole communicating with the horizontal hole and penetrating the lid portion in the vertical direction. .
[0008]
In the block molded by the mold of the present invention, the water collecting holes are provided in the middle part of the block in the longitudinal direction, so that any number of water collecting holes can be provided at any position. The water collecting hole is composed of a horizontal hole penetrating the boundary portion in the horizontal direction and a vertical hole communicating with the horizontal hole and penetrating the lid portion in the vertical direction. The horizontal hole has the smallest cross-sectional area at the center. , and gradually the cross-sectional area becomes larger taper hole toward the sides, the vertical hole upper most area is small, and has a gradually sectional area increases taper hole toward the bottom. By doing in this way, this walkway boundary cover block can be easily manufactured with the formwork of this invention shown below.
[0009]
The mold according to the present invention includes an outer frame in which a cavity is T-shaped by a thin box-shaped lid molding part and a boundary molding part formed so that a bottom part thereof is deep, a small end surface having a small area, and the other end. Is formed by joining the small end faces of two tapered cylindrical halves having a large end face with a large area so that they can be joined and separated from each other, and forming the horizontal hole disposed at the uppermost part of the boundary forming part. A tapered cylindrical shape for forming the vertical hole, wherein the horizontal hole core is joined to the upper surface of the horizontal hole core so as to be freely separable, and the lower end is a small end surface with a small area and the upper end is a large end face with a large area. It is a formwork of the pedestrian road boundary lid block characterized by having a vertical hole core.
[0010]
Since the horizontal hole core half and the vertical hole core have a tapered cylindrical shape, these tapers form a so-called draft, and the core can be easily extracted from the hardened concrete.
[0011]
For example, if a protrusion is formed on one small end surface of a half and a recess is formed on the other small end surface, and the protrusion engages and separates from the recess, the small end surfaces of the two halves are separated from each other. They can be joined to each other so as to be separable.
[0012]
Further, for example, if a protrusion is formed on the lower surface of the vertical hole core and a recess is formed on the upper surface of the horizontal hole core, and the protrusion engages and separates from the recess, the vertical hole core is It can be joined to the upper surface of the steel plate so as to be separable.
[0013]
When the grating is detachably attached to the vertical hole of the pedestrian road boundary lid block of the present invention, the inside of the side groove can be cleaned only by detaching the grating.
[0014]
