Description

本発明は、舗装路の境界や側溝、中央分離帯等に用い、舗装材との境に防草機能を備えた防草機能付ブロックに関するものである。   The present invention relates to a block with a herbicidal function that is used for a boundary of a paved road, a gutter, a median strip, and the like and has a herbicidal function at the boundary with a pavement material.

従来、コンクリートやアスファルトで舗装された舗装路において、歩道と車道の境界や中央分離帯、舗装路脇の側溝等にはコンクリート製の境界ブロックもしくは側溝ブロックが敷設される。そして、コンクリートやアスファルト等の舗装材は、これらブロック本体の舗装路側の側面に接するように打設される。しかしながら、舗装材は寒暖差や車両運行時の振動等により収縮、膨張を繰り返し、年を経るごとにブロック本体の側面と舗装材との間には徐々に隙間が形成される。そして、この状態を放置するとこの隙間に土が溜まって雑草が生育し、舗装路の美観や安全性を損なうという問題点がある。この問題点に関し、下記［特許文献１］には、図１３に示すように、縁石体２の舗装側の側面上部にＬ状の溝状切り欠き部３（防草部）を設け、さらにその溝状切り欠き部３の水平面に断面Ｖ字状の溝３ｃを備えた防草機能を有する縁石に関する考案が開示されている。   Conventionally, in a paved road paved with concrete or asphalt, a concrete boundary block or a side groove block is laid on a boundary between a sidewalk and a roadway, a median strip, a side groove on the side of the paved road, or the like. Then, a paving material such as concrete or asphalt is placed so as to be in contact with the side surface of the block body on the side of the paved road. However, the pavement material repeatedly shrinks and expands due to differences in temperature and vibrations during vehicle operation, and a gap is gradually formed between the side surface of the block main body and the pavement material over the years. If this state is left unattended, soil accumulates in the gaps and weeds grow, which impairs the beauty and safety of the paved road. With regard to this problem, in [Patent Document 1] below, as shown in FIG. 13, an L-shaped groove-shaped notch 3 (weedproof portion) is provided on the side surface of the curb body 2 on the pavement side, and further, A device relating to a curb stone having a weedproof function provided with a groove 3c having a V-shaped cross section in the horizontal surface of the groove-shaped notch 3 is disclosed.

しかしながら、［特許文献１］に記載の考案は、舗装側の側面上部にＬ状の防草部を設けるため、その分、ブロック本体の上部（舗装材からの露出部）の幅が狭くなるという問題点がある。   However, since the device described in [Patent Document 1] is provided with an L-shaped grass protection portion on the side surface of the pavement, the width of the upper portion of the block body (exposed portion from the pavement material) is reduced accordingly. There is a problem.

本発明は上記事情に鑑みてなされたものであり、ブロック本体の幅寸法への影響が少ない防草機能付ブロックを提供することを目的とする。   The present invention has been made in view of the above circumstances, and an object thereof is to provide a block with a herbicidal function that has little influence on the width of the block body.

前記上側の傾斜面３２ａの水平面からの角度を角度θ１とし、前記下側の傾斜面３２ｂの水平面からの角度を角度θ２としたときに、
前記凹条の上側の傾斜面３２ａの角度θ１が下側の傾斜面３２ｂの角度θ２よりも大きく、さらに、前記下側の傾斜面３２ｂの角度θ２が１０°〜３０°であることを特徴とする防草機能付ブロック８０を提供することにより、上記課題を解決する。
（２）上端３４ａが下端３４ｂよりも５ｍｍ〜３０ｍｍ内側に位置することを特徴とする上記（１）記載の防草機能付ブロック８０を提供することにより、上記課題を解決する。 The present invention
(1) In the block with the weed control function provided with the weed control section 30 on the side surface 52 on the pavement side of the block body 50,
The grass-proof portion 30 is a groove that is recessed in a substantially trapezoidal shape or a substantially triangular shape toward the inside of the block body 50, and an upper end 34a thereof is positioned on the inner side of the lower end 34b
The concave stripe has an upper inclined surface 32a extending obliquely upward from the back side, and a lower inclined surface 32b extending obliquely downward from the deep side,
When the angle from the horizontal plane of the upper inclined surface 32a is an angle θ1, and the angle from the horizontal plane of the lower inclined surface 32b is an angle θ2,
The angle θ1 of the upper inclined surface 32a of the recess is larger than the angle θ2 of the lower inclined surface 32b, and the angle θ2 of the lower inclined surface 32b is 10 ° to 30 °. The above problem is solved by providing the block 80 with the herbicidal function.
(2) The above problem is solved by providing the block 80 with the weedproof function according to the above (1), wherein the upper end 34a is located 5 mm to 30 mm inside the lower end 34b.

本発明に係る防草機能付ブロック８０の実施の形態について図面に基づいて説明する。ここで、図１は本発明に係る防草機能付ブロック８０を縁石部を備えた両面型の歩車道境界ブロックに適用した例を示す図である。尚、図１（ａ）はこの防草機能付ブロック８０の正面図を、図１（ｂ）は平面図を、図１（ｃ）は左側面図を、図１（ｄ）は右側面図を、図１（ｅ）は背面図を、図１（ｆ）は底面図を、それぞれ示す。   An embodiment of a block 80 with a weedproof function according to the present invention will be described with reference to the drawings. Here, FIG. 1 is a diagram showing an example in which the block 80 with the grass protection function according to the present invention is applied to a double-sided pedestrian boundary block having a curb portion. 1 (a) is a front view of the block 80 with the weedproof function, FIG. 1 (b) is a plan view, FIG. 1 (c) is a left side view, and FIG. 1 (d) is a right side view. 1 (e) is a rear view, and FIG. 1 (f) is a bottom view.

本発明に係る防草機能付ブロック８０は、図１に示すように、ブロック本体５０と、このブロック本体５０の少なくとも一方の舗装側の側面５２に形成された防草部３０と、を有している。尚、図１では一方の側面５２に防草部３０を形成した例を示しているが、防草部３０は一方の側面５２のみならず、両側の側面に形成しても良い。また、防草部３０は基本的に舗装材の上面位置より若干（後述のＬ２寸法）下に形成する。よって、防草部３０の形成位置は舗装面の位置に準じ、適用する防草機能付ブロック８０によって変化する。これらのことは、後述の各ブロックに適用した例においても同様である。   As shown in FIG. 1, the block 80 with a weedproof function according to the present invention has a block main body 50 and a weedproof portion 30 formed on a side surface 52 on at least one pavement side of the block main body 50. ing. In addition, although the example which formed the grass prevention part 30 in the one side surface 52 is shown in FIG. 1, you may form the grass prevention part 30 not only in the one side surface 52 but in the side surface of both sides. In addition, the weedproof portion 30 is basically formed slightly below the upper surface position of the pavement (L2 dimension described later). Therefore, the formation position of the weed prevention part 30 changes according to the block 80 with a weed prevention function to apply according to the position of a pavement surface. The same applies to an example applied to each block described later.

次に、本発明に係る防草機能付ブロック８０の防草部３０の拡大図を図２に示す。本発明に係る防草部３０は、舗装材が接する側面５２からブロック本体５０の内側に略水平方向に凹んだ凹条で構成され、その断面は上側の傾斜面３２ａと下側の傾斜面３２ｂとを備えた略台形状もしくは略三角形状を呈する。そして、凹条の上端３４ａが下端３４ｂよりも内側に位置することを特徴とする。尚、このように凹条の上端３４ａが下端３４ｂよりも内側に位置することで、転圧による防草部３０内への舗装材の充填性が向上し、防草部３０に空隙が生じることを防止することができる。尚、凹条の上端３４ａと下端３４ｂとの位置の差Ｌ１は大きすぎるとブロック本体５０の幅寸法への影響が大きくなり、小さすぎると舗装材の充填性が低下する。よって、５ｍｍ〜３０ｍｍが好ましく、１０ｍｍ±５ｍｍとすることが特に好ましい。   Next, an enlarged view of the weed control unit 30 of the block 80 with the weed control function according to the present invention is shown in FIG. The grass protection section 30 according to the present invention is configured by a groove that is recessed in a substantially horizontal direction from the side surface 52 in contact with the pavement material to the inside of the block body 50, and the cross section thereof is an upper inclined surface 32a and a lower inclined surface 32b. It has a substantially trapezoidal shape or a substantially triangular shape. And the upper end 34a of a concave strip is located inside the lower end 34b, It is characterized by the above-mentioned. In addition, when the upper end 34a of the concave line is located on the inner side of the lower end 34b in this way, the filling property of the pavement material into the weed prevention unit 30 by rolling pressure is improved, and a gap is generated in the weed prevention unit 30. Can be prevented. If the difference L1 between the positions of the upper end 34a and the lower end 34b of the concave stripe is too large, the influence on the width dimension of the block body 50 becomes large, and if it is too small, the filling property of the pavement material decreases. Therefore, it is preferably 5 mm to 30 mm, and particularly preferably 10 mm ± 5 mm.

そして、本発明に係る防草部３０は前述のように側面５２から内側に向けて凹んだ凹条であるため、露出部分の幅寸法の寸法変化（Ｌ１）が少なく、十分な幅の露出部分を確保することができる。また、露出部分の幅を変えずに埋設部分を拡げる場合でも、幅寸法の変化量（Ｌ１）が少ないためブロック本体５０の体積増加も小さく材料コストも大きく増大しない。   And since the grass-proof part 30 which concerns on this invention is a concave strip dented inward from the side surface 52 as mentioned above, there is little dimensional change (L1) of the width dimension of an exposed part, and the exposed part of sufficient width | variety Can be secured. Even when the embedded portion is expanded without changing the width of the exposed portion, the amount of change in the width dimension (L1) is small, so that the volume of the block body 50 is not increased and the material cost is not significantly increased.

尚、上側の傾斜面３２ａの角度θ１、下側の傾斜面３２ｂの角度θ２は、舗装材の充填性を良好とするために、上側の傾斜面３２ａの角度θ１を下側の傾斜面３２ｂの角度θ２よりも大きくし、特に、上側の傾斜面３２ａの角度θ１は３０°〜４０°が好ましく、３５°±２°が最も好ましい。また、下側の傾斜面３２ｂの角度θ２は１０°〜３０°とし、２０°±４°が最も好ましい。尚、角度θ１、角度θ２が上記の範囲を超えると充填性は向上するものの、防草部３０の屈曲が緩やかになって雑草の根の成長防止効果が低減する虞が有る。また、角度θ１、角度θ２が上記の範囲を下回ると防草部３０が鋭角となって舗装材の充填性が低下する虞が有る。
The angle θ1 of the upper inclined surface 32a, the angle θ2 of the lower inclined surface 32b, to a good good filling of the shop Paneling, the angle θ1 of the upper inclined surface 32a of the lower inclined surface the size comb than the angle θ2 of 32b, in particular, the angle θ1 of the upper inclined surface 32a is preferably 30 ° to 40 °, most preferably 35 ° ± 2 °. The angle θ2 of the lower inclined surface 32b is 10 ° to 30 °, and most preferably 20 ° ± 4 °. When the angles θ1 and θ2 exceed the above ranges, the filling performance is improved, but the bending of the weed control section 30 becomes gentle and there is a possibility that the effect of preventing the growth of weed roots is reduced. Moreover, if the angle θ1 and the angle θ2 are less than the above ranges, the grassproof portion 30 may become an acute angle and the filling property of the pavement material may be reduced.

また、舗装材の上面１から防草部３０の上端３４ａまでの距離Ｌ２は短い方がブロック本体５０と舗装材との間に隙間が生じた場合でも雑草の根の成長スペースが浅く制限され、防草効果の面から好ましい。よって、距離Ｌ２は５ｍｍ〜３０ｍｍが好ましく、特に１０ｍｍ±５ｍｍが好ましい。また、凹条の幅Ｌ３は２０ｍｍ〜６０ｍｍが好ましく、特に３０ｍｍ±５ｍｍが好ましい。さらに、防草部３０の側面５２からの深さＬ４は２０ｍｍ〜５０ｍｍが好ましく、特に２５ｍｍ±５ｍｍが好ましい。そして、本発明に係る防草部３０は、上記寸法と上記の角度θ１、θ２の範囲を取ることで適度に屈曲し、この屈曲（傾斜面３２ａ、３２ｂ）による接触抵抗によって舗装材の収縮を防止する。また、仮に隙間が生じた場合でも、この屈曲によって雑草の根の成長は阻害され、雑草の成長を防止することができる。   In addition, when the distance L2 from the upper surface 1 of the pavement material to the upper end 34a of the weed protection unit 30 is shorter, even if a gap is generated between the block main body 50 and the pavement material, the growth space of the weed root is limited shallowly, It is preferable in terms of the grass effect. Therefore, the distance L2 is preferably 5 mm to 30 mm, and particularly preferably 10 mm ± 5 mm. Further, the width L3 of the concave stripe is preferably 20 mm to 60 mm, particularly preferably 30 mm ± 5 mm. Furthermore, the depth L4 from the side surface 52 of the weed prevention unit 30 is preferably 20 mm to 50 mm, and particularly preferably 25 mm ± 5 mm. And the weed prevention part 30 which concerns on this invention bends moderately by taking the range of the said dimension and said angle (theta) 1 and (theta) 2, and the shrinkage | contraction of pavement material by the contact resistance by this bending (inclined surface 32a, 32b). To prevent. Even when a gap is generated, the growth of weed roots is inhibited by this bending, and the growth of weeds can be prevented.

また、本発明の防草部３０はブロック本体５０の垂直方向に凹みを有さない。ここで、例えば従来技術に記したＬ状の防草部のように垂直方向に凹み（断面Ｖ字状の溝３ｃ）を有する場合、この凹み部分の舗装材に自身の膨張収縮時の剪断応力が集中し破断する可能性がある。そして、凹み部分の舗装材が破断すると舗装材の収縮防止機能は劣化する。この点、本発明の防草部３０はブロック本体５０の内側に向けて略水平方向に形成し、傾斜面３２ａ、３２ｂによる接触抵抗によって舗装材の収縮を防止する。このため、舗装材の収縮時の応力は特定の部位に集中せず破断も生じることが無い。これにより、舗装材の収縮防止機能及び防草機能を長期間維持することができる。   In addition, the grass protection unit 30 of the present invention does not have a dent in the vertical direction of the block body 50. Here, for example, in the case of having a dent in the vertical direction (groove 3c having a V-shaped cross section) as in the L-shaped grass-proof portion described in the prior art, the shear stress at the time of expansion / contraction of the pavement material in this dent portion. May concentrate and break. And if the pavement material of a dent part breaks, the shrinkage prevention function of a pavement material will deteriorate. In this regard, the weedproof portion 30 of the present invention is formed in a substantially horizontal direction toward the inside of the block main body 50, and prevents the pavement material from contracting by the contact resistance by the inclined surfaces 32a and 32b. For this reason, the stress at the time of shrinkage | contraction of a pavement material does not concentrate on a specific site | part, but a fracture | rupture does not arise. Thereby, the shrinkage prevention function and the weed prevention function of the pavement material can be maintained for a long time.

次に、本発明に係る防草機能付ブロック８０の適用例を示す。ここで、図３〜図１２の（ａ）は各適用例の正面図を示し、図３〜図１２の（ｂ）は各適用例の平面図を示し、図３〜図１２の（ｃ）は各適用例の左側面図を示し、図３〜図１２の（ｄ）は各適用例の右側面図を示し、図３〜図１２の（ｅ）は各適用例の背面図を示し、図３〜図１２の（ｆ）は各適用例の底面図を示す。   Next, an application example of the block 80 with the grass protection function according to the present invention will be shown.
