Description
【０００１】[0001]
本考案は公園その他の遊歩道などに敷設される舗装用の路盤表装材に関し、特 に直列または様々な曲率に見栄え良く思い通り極簡単に敷設できるようにした路 盤表装材に関する。 The present invention relates to a pavement surface covering material for pavement laid on a park or other promenade, etc., and more particularly, to a subgrade surface covering material which can be laid in a straight line or at various curvatures so that it can be laid very easily as desired.
【０００２】[0002]
従来、コンクリートなどを素材にして成形された路盤表装材を公園内の遊歩道 などに敷き詰めて舗装することが一般に広く行われているが、その種の路盤表装 材は方形体状にして整地した路床上に単に設置するだけのものが殆どであり、上 から荷重を受けたときには隣接する路盤表装材が相互にＶ字形に傾くなどして表 面の周縁部が破損して美観を損なうことがあった。これを防止するには隣接する 路盤表装材の間に僅かに間隙をあければよいが、路盤表装材を一定の間隔にして 順に配置する作業は煩わしく困難なものである。 In the past, it has been widely practiced to spread the pavement surface covering material formed of concrete or the like on the promenades in parks, etc. Most of them are simply installed on the floor, and when a load is applied from above, adjacent roadbed surface materials may be inclined in a V-shape with each other, and the peripheral edge of the surface may be damaged, degrading the appearance. Was. In order to prevent this, it is only necessary to provide a slight gap between the adjacent roadbed surface covering materials, but it is cumbersome and difficult to arrange the roadbed surface covering materials at regular intervals in order.
【０００３】 そこで、近年にあって側面に目地幅調整用の突起を形成した路盤表装材が実用 化されている。その一例を図１２に示しているように、その種の路盤表装材Ａは 方形体状に成形した本体部Ｂの四側面Ｂ１〜Ｂ４に各１〜２条の突起Ｃを形成し てあり、その突起Ｃの突出分で目地幅を容易に調整することができる。図１３は その敷設例を示した平面図であり、この図から明らかなように突起Ｃを形成した 路盤表装材Ａによれば、その突起Ｃを相互に相手方の側面に突き合わせることに より、容易に一定幅の目地を形成することができる。[0003] Therefore, in recent years, a roadbed surface covering material having a projection for adjusting joint width formed on a side surface has been put to practical use. As shown in FIG. 12, one example of such a roadbed surface covering material A is formed with one or two protrusions C on each of four side surfaces B1 to B4 of a main body B formed in a rectangular shape. The joint width can be easily adjusted by the protrusion of the protrusion C. FIG. 13 is a plan view showing an example of the laying. As is apparent from this figure, according to the roadbed surface covering material A having the projections C formed thereon, Joints having a constant width can be easily formed.
【０００４】[0004]
しかしながら、上記従来のように側面に突起を形成した路盤表装材にして、こ れを一定の目地幅で直列状に規則正しく容易に並べられるものの、曲線的な配列 は非常に困難なものであった。 However, although it is a conventional roadbed material with projections formed on the side surface as in the above-mentioned conventional case, it can be easily and regularly arranged in series with a fixed joint width, but it is extremely difficult to arrange it in a curved line. .
【０００５】 すなわち、曲線的に配列する場合には突起が相互に係わり合わないので目地幅 の調整が難しく時間がかかる上、敷設後には横ずれを生じ、しかも本体部が方形 状であるので曲線的な配列にできても目地が三角形状に大きく広がって見栄えを 損なうという欠点があった。[0005] That is, in the case of a curved arrangement, it is difficult to adjust the joint width because the projections do not relate to each other, it takes time, and a lateral displacement occurs after the laying, and the main body has a square shape. Even if it can be arranged in a proper manner, the joints are greatly spread in a triangular shape, and the appearance is impaired.
【０００６】 このように、曲線的な配列が困難であることは、施工場所である遊歩道その他 が直線状であるとは限らず、寧ろ曲線的な敷設を要求されることが多いことから して致命的な欠点であった。[0006] As described above, the difficulty of the curved arrangement means that the promenade or the like as the construction site is not necessarily straight, but rather a curved laying is often required. It was a fatal drawback.
【０００７】 これに関係し、従来では台形状の路盤表装材も存在したが、この種のものは側 面を突き合わせて敷設するので曲率を変えることができず利便性に欠けるもので あった。また、その欠点を解消するべく形状の異なる数種類を取り揃えたものも 存在しているが、それらは決められた順番通りに敷設しなければならないなど作 業性に難があった。[0007] In this connection, there has been a trapezoidal roadbed surface covering material in the past, but since this type is laid with its side surfaces abutting each other, the curvature cannot be changed and the convenience is lacking. There are also several types with different shapes in order to solve the drawbacks, but they have to be laid in a predetermined order, which has been difficult to work.
【０００８】 そこで、本考案の目的は、直列または様々な曲率に見栄え良く思い通り極簡単 に敷設することのできる路盤表装材を提供することにある。[0008] Therefore, an object of the present invention is to provide a roadbed surface covering material that can be laid in a straight line or with various curvatures with good appearance and as easily as desired.
【０００９】[0009]
本考案は上述の目的を達成するため、本体部を四角形状の表面をもつブロック にして該本体部の側面に目地幅調整用の突起を形成した路盤表装材において、前 記本体部の表面を台形状にして前記突起を該本体部の非平行な両側面に互い違い に形成し、その突起は一端側が頂部として前記本体部の両側面中央部より***し 他端がそれぞれ本体部の対角に向けて傾斜状に延びていることを特徴とする路盤 表装材を提供するものである。 In order to achieve the above object, the present invention provides a roadbed surface covering material in which a main body is formed as a block having a square surface and a projection for adjusting joint width is formed on a side surface of the main body. In a trapezoidal shape, the protrusions are alternately formed on the non-parallel side surfaces of the main body, and the protrusions are raised at one end side as a top from the center of both side surfaces of the main body portion, and the other ends are each at a diagonal of the main body portion. It is intended to provide a roadbed surface covering material characterized by extending in an inclined manner toward the road surface.
【００１０】 特に、本考案ではより好適な態様として、突起の頂部に丸みを付けている。ま た、突起の上端縁を本体部の表面より低くし、更に本体部における平行する両側 面の少なくとも一方に、表面より高さの低い突面部を形成している。Particularly, in the present invention, as a more preferable embodiment, the top of the projection is rounded. Further, the upper end edge of the projection is lower than the surface of the main body, and a projection lower than the surface is formed on at least one of the two parallel side surfaces of the main body.
【００１１】 ここで、本願の路盤表装材は天然石や合成樹脂あるいはゴムなど種々の材料に より形成することができるが、加工性や強度の点ではコンクリート製にすること が望ましい。そこで、請求項５の考案では顔料を含浸したコンクリートにより本 体部と突起および突面部を一体に形成している。なお、顔料を加えることにより 様々な色合いに着色して天然石風、或いは天然石には無い色合いにすることがで きる。Here, the roadbed surface covering material of the present invention can be formed from various materials such as natural stone, synthetic resin, or rubber, but is preferably made of concrete in terms of workability and strength. Therefore, in the invention of claim 5, the main body, the projection and the protruding surface are integrally formed by the concrete impregnated with the pigment. It should be noted that by adding a pigment, it can be colored in various colors to give a natural stone style or a color not found in natural stone.
【００１２】 特に、請求項６の考案のように本体部の表面を粗面状にすることで、天然石風 の割肌にすることができる。In particular, by making the surface of the main body part rough as in the invention of claim 6, it is possible to obtain a natural stone-like split skin.
【００１３】[0013]
以下、本考案の実施の形態を図面に基づいて詳細に説明する。先ず、図１は舗 装した路盤の断面を示す。図１において、１は遊歩道その他の路床であり、この 路床１は所定の深さまで掘削してからその上に砕石２と砂３が順に敷き詰められ る。砕石２は１００ｍｍ程度の層状にしてタンデムローラなどの転圧機にて転圧 され、その上に砂３が３０ｍｍ程度の層状にして敷き詰められる。 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, FIG. 1 shows a cross section of a paved roadbed. In FIG. 1, reference numeral 1 denotes a promenade and other subgrades. The subgrade 1 is excavated to a predetermined depth, and then crushed stones 2 and sand 3 are spread over the excavation. The crushed stone 2 is formed into a layer of about 100 mm, and is compacted by a rolling machine such as a tandem roller, and sand 3 is layered thereon in a layer of about 30 mm.
【００１４】 そして、本考案に係る路盤表装材４は、例えば上述のように砕石２と砂３とで 整地した路床１の上に一面に敷設される。その路盤表装材４は例えばコンクリー ト製であり、好ましくは透水性を有するコンクリートブロックにして一定の間隔 をあけて砂３の上に順に設置される。なお、通常のコンクリートであっても、こ れはモルタルを使用しない後述の乾式施工であるため目地から雨水などを路盤に 浸透させることができる。[0014] The roadbed surface covering material 4 according to the present invention is laid on the entire surface of the subgrade 1 laid with the crushed stone 2 and the sand 3 as described above, for example. The roadbed surface covering material 4 is made of concrete, for example, and is preferably made of a concrete block having water permeability and is sequentially placed on the sand 3 at regular intervals. Even for ordinary concrete, since this is a dry-type construction described below that does not use mortar, rainwater and the like can permeate the roadbed from the joint.
【００１５】 図２は、その路盤表装材４を示した斜視図である。この図で明らかにするよう に、路盤表装材４は四角形状の表面５Ａをもつブロックにした本体部５をベース にして構成される。本体部の表面５Ａは複数の凹凸を不規則に形成して粗面状に 加工してあり、更に全体に着色を施して天然石風の色合いに仕上げている。FIG. 2 is a perspective view showing the roadbed surface covering material 4. As apparent from this figure, the roadbed surface covering material 4 is configured based on a main body portion 5 formed into a block having a square surface 5A. The surface 5A of the main body is formed into a rough surface by forming a plurality of irregularities irregularly, and is further colored throughout to give a natural stone-like hue.
【００１６】 また、本体部５には表面５Ａと直交する側面５Ｂ，５Ｃに突起６と突面部７を 一体にして形成し、それら突起６と突面部７を利用して各路盤表装材４を見栄え 良く思い通り容易に敷設できるようにしている。Further, the main body 5 is formed integrally with the projections 6 and the protruding portions 7 on the side surfaces 5 B and 5 C orthogonal to the surface 5 A, and the roadbed surface covering material 4 is formed by using the protrusions 6 and the protruding portions 7. It looks good and easy to lay as you wish.
【００１７】 次に、図３は路盤表装材４の平面図を示す。この図で明らかなように、本体部 ５はその表面５Ａを線対称の台形状に形成して該本体部の非平行な両側面５Ｂ， ５Ｂに突起６，６を形成している。それらの突起６はそれぞれ側面５Ｂの片側に あって互い違いに形成されている。特に、それらの突起６は左右の一端側が丸み を付けた頂部６Ａとして側面５Ｂの中央部より***し、また他端側がそれぞれ本 体部５の対角８Ａ，８Ｂに向けて延びており、それぞれ本体部の側面５Ｂに対し て一定の勾配をもって傾斜する傾斜面として形成されている。Next, FIG. 3 shows a plan view of the roadbed surface covering material 4. As is clear from this figure, the main body 5 has its surface 5A formed in a line-symmetric trapezoidal shape, and has projections 6, 6 formed on the non-parallel side surfaces 5B, 5B of the main body. The projections 6 are formed on one side of the side surface 5B and are formed alternately. In particular, the protrusions 6 have left and right ends protruding from the center of the side surface 5B as rounded tops 6A, and the other ends extend toward diagonals 8A and 8B of the main body 5, respectively. It is formed as an inclined surface that is inclined with a constant gradient with respect to the side surface 5B of the main body.
【００１８】 一方、側面５Ｂと交わる面すなわち互いに平行する両側面５Ｃ，５Ｄのうち、 短辺側の側面５Ｃには突面部７が形成される。突起６が左右方向に目地を形成す るものであるのに対し、この突面部７は路盤表装材を敷設したときに前後方向に 一定幅の目地を形成するものである。ここで、突面部７は側面５Ｃと平行する平 滑面にして、側面５Ｃの全幅で２ｍｍ程度突出させてある。なお、突面部７は長 辺側の側面５Ｄに形成するか、または側面５Ｃ，５Ｄに相対して形成するように してもよい。また、その形状は平滑面状に限らず従来のように筋状にして側面５ Ｃまたは５Ｄの両側に形成することもできる。On the other hand, of the surfaces intersecting with the side surface 5B, that is, the side surfaces 5C and 5D parallel to each other, a protruding surface portion 7 is formed on the side surface 5C on the short side. The projections 6 form joints in the left-right direction, whereas the protruding surface portions 7 form joints having a constant width in the front-rear direction when the roadbed surface covering material is laid. Here, the protruding surface portion 7 is a smooth surface parallel to the side surface 5C, and protrudes by about 2 mm over the entire width of the side surface 5C. The protruding portion 7 may be formed on the long side surface 5D, or may be formed opposite to the side surfaces 5C and 5D. Further, the shape is not limited to a smooth surface shape, and may be formed in a streak shape as in the related art and formed on both sides of the side surface 5C or 5D.
【００１９】 次に、図４は図３におけるＸ−Ｘ線断面、図５はＹ−Ｙ線断面を示す。また、 図６は路盤表装材４の側面図である。これらの図で明らかなように、突起６は所 定の高さにして本体部の底面５Ｅから表面５Ａより低い位置まで一連に形成され る。例えば、本体部５の高さを６５ｍｍとして、突起６は本体部の底面５Ｅから ５０ｍｍの高さをもって形成される。一方、突面部７もその突起６と同じ高さに して形成される。そして、本体部５はその表面５Ａから突起６や突面部７の上端 縁までの距離を表装部９とし、この表装部９の周面を含めて表面５Ａを粗面状に 形成している。Next, FIG. 4 shows a cross section taken along line XX in FIG. 3, and FIG. 5 shows a cross section taken along line YY in FIG. FIG. 6 is a side view of the roadbed surface covering material 4. As is clear from these figures, the projections 6 are formed at a predetermined height from the bottom surface 5E of the main body to a position lower than the surface 5A. For example, assuming that the height of the main body 5 is 65 mm, the protrusion 6 is formed with a height of 50 mm from the bottom surface 5E of the main body. On the other hand, the protruding surface 7 is also formed at the same height as the protrusion 6. The distance from the surface 5A of the main body 5 to the upper end edge of the projection 6 or the protruding surface 7 is defined as a surface mounting portion 9, and the surface 5A including the peripheral surface of the surface mounting portion 9 is formed in a rough surface shape.
【００２０】 ここで、上述のように構成される路盤表装材４は、例えば以下のようにして製 造される。図７に基づいて説明すれば、１０は路盤表装材の成形型であり、この 成形型１０は例えばゴム製にして、その底部１１に複数の凹凸が不規則に形成さ れている。そして、路盤表装材４を製造するには、その種の成形型１０を用い、 その中にコンクリート１２を充填するのである。コンクリート１２は混練時に鉱 物質などの固体粉末で成る種々の顔料を加えて着色し、これを成形型１０に充填 して一定時間放置する。そして、コンクリート１２の固化後に成形型１０より固 形物を取り出すことにより、本体部５と突起６および突面部７が一体に成形され た路盤表装材４を得る。Here, the roadbed surface covering material 4 configured as described above is manufactured, for example, as follows. Referring to FIG. 7, reference numeral 10 denotes a molding die for a roadbed surface covering material. The molding die 10 is made of, for example, rubber, and a plurality of irregularities are irregularly formed on a bottom portion 11 thereof. Then, in order to manufacture the roadbed surface covering material 4, a molding die 10 of that kind is used, and concrete 12 is filled therein. The concrete 12 is colored by adding various pigments made of a solid powder such as a mineral substance at the time of kneading, filling the mold 10 with the pigment, and allowing it to stand for a certain period of time. Then, after solidification of the concrete 12, the solid object is taken out from the molding die 10 to obtain the roadbed surface covering material 4 in which the main body portion 5, the projection 6, and the protruding surface portion 7 are integrally formed.
【００２１】 このようにして得られる路盤表装材４は、通常の天然石などがモルタルなどの 結合材を下地や目地に充填して使用するのに対し、乾式施工といって上述のよう に砕石２や砂３で整地した路床１の上に単に設置して敷設するのであり、それで も突起６が相互に噛み合うため横ずれを生じない。また、この乾式施工により雨 水が目地から砕石層へと浸透する舗装を提供することができる。そして、特に本 発明の路盤表装材４によれば、直列または様々な曲率に見栄え良く思い通り容易 に並べることができるのである。The roadbed surface covering material 4 obtained as described above is used in a dry construction method as described above, while ordinary natural stone or the like is used by filling a base material or joints with a binder such as mortar. It is simply installed and laid on the subgrade 1 that has been leveled with sand or sand 3, and even so, the protrusions 6 mesh with each other, so that no lateral displacement occurs. In addition, the pavement through which rainwater permeates from the joint to the crushed stone layer can be provided by this dry construction. In particular, according to the roadbed surface covering material 4 of the present invention, it is possible to easily and easily arrange them in a series or at various curvatures as desired.
【００２２】 その一例として、図８に路盤表装材４を直列状に敷設した状態を示す。この図 のように路盤表装材４を直列状に敷設するには、路盤表装材４，・・を交互に逆 向きにして突起６を噛み合わせるのである。これにより、各路盤表装材４は突起 ６同士および突起６と側面５Ｂの３点で接触し合い、配列方向と直交する方向へ の移動が規制され、しかも配列方向では突起６により目地Ｍの幅を容易に調整で きるので施工を容易にして綺麗に仕上げられる。また、目地Ｍが形成されること により、隣接する路盤表装材４が相互にＶ字形に傾くなどしても表面の周縁部が 破損するのを防止できる。なお、複数列の施工では突面部７に他の路盤表装材の 突面部のない側面５Ｄを突き合わせるようにし、縦横に形成される目地には突起 ６や突面部７の遮蔽および歩行感の向上を目的として、細かい砕石などを充填す る。As an example, FIG. 8 shows a state in which roadbed surface covering materials 4 are laid in series. In order to lay the roadbed surface covering materials 4 in series as shown in this figure, the roadbed surface covering materials 4,... As a result, the roadbed surface covering materials 4 come into contact with each other at the projections 6 and between the projections 6 at the three points of the side surface 5B, and the movement in the direction orthogonal to the arrangement direction is regulated. Can be easily adjusted, making the construction easy and beautifully finished. The formation of the joints M can prevent the peripheral edge of the surface from being damaged even if the adjacent roadbed surface covering materials 4 are inclined in a V-shape with each other. In the case of the construction of a plurality of rows, the side face 5D of the other roadbed surface covering material without the protruding portion is abutted against the protruding surface portion 7, and the joints formed vertically and horizontally are shielded by the protruding portion 6 and the protruding surface portion 7 and the walking feeling is improved. For this purpose, fine crushed stones are filled.
【００２３】 次に、図９〜図１１は路盤表装材４を円弧状に敷設する状態を示す。図９は曲 率の大きな円弧にして敷設する例であり、この場合には直列に並べるときと同じ ように路盤表装材４，・・を交互に逆向きにして突起６を噛み合わせるようにす る。特に、本例の場合には突起６を噛み合わせたまま各路盤表装材４の一角を近 接させるようにして敷設すればよい。このように、円弧状に敷設する場合でも突 起６の噛み合いで路盤表装材４の移動を規制できるし、本体部が台形状であるか ら目地幅が極端に広くなることもなく見栄えを損なわない。Next, FIGS. 9 to 11 show a state in which the roadbed surface covering material 4 is laid in an arc shape. FIG. 9 shows an example of laying in an arc having a large curvature. In this case, the roadbed surface covering materials 4,... You. In particular, in the case of this example, it is only necessary to lay the roadbed surface covering material 4 such that one corner thereof is close to the other while the projections 6 are engaged. In this way, even when laid in an arc shape, the movement of the roadbed surface covering material 4 can be restricted by the engagement of the protrusions 6, and the appearance is impaired without the joint width becoming extremely wide because the main body is trapezoidal. Absent.
【００２４】 図１０および図１１でも同様であるが、これらの施工例では曲率をより小さく して敷設することができる。何れの場合も路盤表装材４は同じ向きにして順に配 列するのであるが、図１０では各路盤表装材４の外側の一角を近接させて図９の 場合より曲率を小さくでき、更に図１１の施工例によれば各路盤表装材４の内側 の一角を近接させて図１０より曲率を小さくすることができる。特に、このよう な円弧状の配列に際し、突起６の頂部６Ａに丸みを付けてあるから噛み合わせを 適正に行える。The same applies to FIGS. 10 and 11, but in these construction examples, the laying can be performed with a smaller curvature. In any case, the roadbed surface covering materials 4 are arranged in the same direction in order. In FIG. 10, the outer corner of each roadbed surface covering material 4 is made closer to make the curvature smaller than that in the case of FIG. According to the construction example of (1), the inner corner of each roadbed surface covering material 4 can be made closer to make the curvature smaller than in FIG. In particular, in such an arc-shaped arrangement, the top 6A of the projection 6 is rounded, so that the engagement can be performed properly.
【００２５】 このように、本考案に係る路盤表装材４では、直列状に敷設したり、円弧状に 敷設したりするにしても目地幅の調整が容易であり、しかも目地が形成されるこ とからして表面５Ａの周縁部の破損を防止することもでき、且つ突起６の噛み合 いにより移動を規制することができる。特に、本体部５が台形状であるから円弧 状に配置しても目地幅を可及的小さくして美観を向上させることができる。As described above, in the roadbed surface covering material 4 according to the present invention, the joint width can be easily adjusted and the joint can be formed even when the joint is laid in series or in an arc shape. In addition, it is possible to prevent the peripheral edge of the surface 5A from being damaged, and to restrict the movement by the engagement of the projections 6. In particular, since the main body 5 has a trapezoidal shape, the joint width can be made as small as possible and the appearance can be improved even if the main body 5 is arranged in an arc shape.
【００２６】 なお、本体部５は左右対称にしているが、本考案によれば本体部の表面が左右 対称な台形状であることに制限されるものでなく、例えば非平行な側面５Ｂの一 方を互いに平行する側面５Ｃ，５Ｄに直交させるようにしてもよい。また、本体 部の表面５Ａを粗面状にする方法として、表面にショット加工を施すようにして もよい。更に、本願の路盤表装材４によれば、公園の遊歩道などに限らず、植木 周りの縁石や建物内外の敷石などとしても利用できる。Although the main body 5 is symmetric, the surface of the main body is not limited to a symmetric trapezoid according to the present invention. The sides may be orthogonal to the side surfaces 5C and 5D that are parallel to each other. Also, as a method of roughening the surface 5A of the main body, a shot process may be performed on the surface. Further, according to the roadbed surface covering material 4 of the present application, it can be used not only as a promenade in a park but also as a curb around a tree plant or a paving stone inside and outside a building.
【００２７】[0027]
以上の説明で明らかなように、本考案にかかる路盤表装材によれば、その本体 部を台形状のブロックにしているので非平行な両側面を近接させて直列あるいは 様々な曲率に配列することができ、とりわけ円弧状に配列したときでも相互間に 形成される三角形状の目地が小さくなって仕上がり状態が良好となり、しかも非 平行な両側面に突起を互い違いに形成しているから敷設時には目地幅の調整を容 易にして見栄え良く綺麗に配列することができる。特に、突起はその一端側を丸 みを付けた頂部として本体部の側面より***させているので、敷設時には突起の 一端が互いに噛み合って横ずれしない。 As is clear from the above description, according to the roadbed surface covering material according to the present invention, since the main body portion is a trapezoidal block, the non-parallel side surfaces are brought close to each other and arranged in series or at various curvatures. In particular, even when arranged in an arc, the triangular joints formed between them are small and the finished state is good, and the projections are alternately formed on both non-parallel sides, so that the joints are laid when laying. The width can be easily adjusted, and the arrangement can be made nicely and neatly. In particular, since the projection is raised from the side surface of the main body portion at one end side as a rounded top, one end of the projection is engaged with each other at the time of laying and does not shift sideways.
【００２８】 また、突起の上端縁を本体部の表面より低くしたため、路盤表装材が上からの 荷重で傾くなどしても突起で表面周縁部が破壊されることがなく、しかも敷設後 には目地に細かい砕石を充填するなどして突起を遮蔽することもできる。その上 、本体部の平行する側面に突起と同じ高さの突面部を形成しているので、複数列 にして敷設する場合でも縦横に目地を形成することができる。In addition, since the upper edge of the projection is lower than the surface of the main body, even when the surface material of the roadbed is inclined by a load from above, the peripheral edge of the surface is not broken by the projection. The protrusions can be shielded by filling the joints with fine crushed stone. In addition, since the protruding portions having the same height as the protrusions are formed on the parallel side surfaces of the main body, joints can be formed vertically and horizontally even when laying in a plurality of rows.
【００２９】 更に、本体部と突起をコンクリートで一体に成形しているので加工性がよく堅 牢であり、特にコンクリートに顔料を加えているからコンクリート製にして天然 石の色合いに調整することができる。しかも、本体部の表面を粗面状にしている ため人工的でなく自然の景観を損なわず、且つ滑り防止としての効果も得られて 安全である。Further, since the main body and the projections are integrally formed of concrete, the workability is good and robust. In particular, since the pigment is added to the concrete, it can be made of concrete and adjusted to the color of natural stone. it can. In addition, since the surface of the main body is made rough, it is not artificial and does not impair the natural scenery, and the effect of preventing slippage is obtained, which is safe.
