(57) [Abstract] [PROBLEMS] When inserting a joint plate between boundary blocks, fine adjustment of the gap must be performed without any trouble. In addition, when arranging the boundary blocks, the joint plates were misaligned, so it was necessary to position them. Furthermore, if the joint plate is not adhered between the boundary blocks, a large amount of adhesive is used, or its function is not fulfilled, resulting in a drastic decrease in adhesive strength. Therefore, it is an object of the present invention to provide a concrete boundary block having a joint board which can efficiently perform the construction of the concrete boundary block by a simple work and can surely obtain a stable adhesive force. A joint plate (2) is integrally provided at one end of a block body (1) via an insert (3), and a groove hole (21) for adhesion is formed at the other end surface of the joint plate (2) to form a joint plate (2). The filling groove 22 is formed from the upper surface to the vicinity of the center of the slot 21.
Description
【0001】[0001]
本考案は道路工事又は土地境界の施工に使用する目地板を有するコンクリ−ト 境界ブロックに関する。 The present invention relates to a concrete boundary block having a joint board used for road construction or land boundary construction.
【0002】[0002]
従来、道路工事又は土地境界の施工などの土木工事に於いて、コンクリ−ト境 界ブロックを使用する際には、境界ブロックを先に並べて置き、該境界ブロック の間にセメントが細い左官コテで押し込まれて気密性を保持させていた。しかし セメントの押し込む作業は、天候に左右されて工期が遅れたり、その作業に熟練 技能を必要とするため素人が容易に応援出来なかった。このため、本考案者が実 用新案登録第3006815号「コンクリ−ト境界ブロック用目地板」を提案し 、これを使用して施工すれば、天候に余り左右されず、且つ作業が簡単で誰にで もコンクリ−ト境界ブロックの施工が出来るようになった。この目地板は弾力性 を有し、境界ブロック間に接着剤を流し込むことにより、気密性が保持されるも のであった。 Conventionally, when using concrete boundary blocks in civil works such as road construction or construction of land boundaries, the boundary blocks are placed side by side, and a plaster trowel with thin cement between the boundary blocks is used. It was pushed in and kept airtight. However, the work of pushing cement in was delayed due to the weather, and the work required expert skills, so amateurs could not easily support it. For this reason, the inventor of the present invention has proposed practical model registration No. 3006815 "joint board for concrete boundary block", and if the construction is performed using this, it is not affected by the weather and the work is easy. It is now possible to construct concrete boundary blocks even in Japan. This joint board had elasticity and the airtightness was maintained by pouring the adhesive between the boundary blocks.
【0003】[0003]
しかしながら、前記目地板は予め並べられた境界ブロックの間に挿入する際、 境界ブロックの隙間が狭い時には、必要な隙間を確保するために後方の境界ブロ ックを移動させなければならず、面倒であった。又、境界ブロックの隙間が広過 ぎる時には、且つ目地板を挿入した後から後方の境界ブロックを押し付けて密着 させなければならず、境界ブロックの隙間の微調節は、目地板を挿入する際に必 ず行わなければならなかった。しかも境界ブロックを並べる際、凹みがあると目 地板が境界ブロックの間で、下方に下がってしまい、その目地板を持ち上げるに は大変手間が掛り、且つ突部があると、目地板が境界ブロックの上部や横部から 出てしまい、その都度、両境界ブロック間の地面を平らに削ったりしてうまく収 まるように位置決めをしなければならなかった。更に前記目地板は境界ブロック の間に密着されていないと接着剤を多く使用したり、或いは接着剤の役目が果せ ず、接着力が激減する等の問題点があった。 However, when the joint board is inserted between the boundary blocks arranged in advance, if the clearance between the boundary blocks is small, the rear boundary block must be moved in order to secure the necessary clearance, which is troublesome. Met. In addition, when the boundary block gap is wide, and after the joint plate is inserted, the rear boundary block must be pressed to make a close contact.Fine adjustment of the boundary block gap is required when inserting the joint plate. I had to do it. Moreover, when arranging the boundary blocks, if there is a dent, the joint plate will fall downward between the boundary blocks, and it will take a lot of time to lift the joint plate, and if there is a protrusion, the joint plate will be the boundary block. I had to get out of the upper and side parts of the building, and every time I had to position it so that it would fit well by grounding the ground between the boundary blocks. Further, if the joint board is not adhered between the boundary blocks, a large amount of adhesive is used, or the adhesive cannot serve its purpose, resulting in a drastic decrease in adhesive strength.
【0004】 本考案は境界ブロックを単に並べると共に目地板の充填溝から接着剤を流し込 むだけの簡単な作業でコンクリ−ト境界ブロックの施工が効率良く行える目地板 を有するコンクリ−ト境界ブロックを提供する。又、他の目的として、目地板の 位置決め作業を省略すると共に安定した接着力が必ず得られる目地板を有するコ ンクリ−ト境界ブロックを提供するにある。The present invention is a concrete boundary block having a joint board which can be efficiently constructed by simply arranging the boundary blocks and pouring an adhesive from a filling groove of the joint board. I will provide a. Another object of the present invention is to provide a concrete boundary block having a joint plate which can omit the positioning work of the joint plate and surely obtain a stable adhesive force.

上記問題点を解決するために本考案は成されたものであり、つまり、ブロック 体の一端に目地板がインサ−トを介して一体に設けられ、且つ前記目地板の他端 面に接着用の溝穴を形成し、前記目地板の上面から前記溝穴の中心付近に渡って 充填溝を穿設させる構造とする。 The present invention has been made to solve the above problems, that is, a joint plate is integrally provided at one end of a block body through an insert, and is attached to the other end surface of the joint plate. The groove is formed, and the filling groove is formed from the upper surface of the joint plate to the vicinity of the center of the groove.
【0006】[0006]
図1,図2は本考案の実施形態を図であり、これに基づき説明する。(1)は 道路工事又は土地境界の施工に使用するコンクリ−ト境界ブロック体である。( 2)はブロック体(1)の一端面へ一体に設けた目地板であり、該目地板(2) の形状はブロック体(1)の端面と同一形状で且つその厚さが15mm前後である。 また前記目地板(2)の表側端面には、円形或いは多角形で且つその深さが 0.5 mm〜2mmの接着用の溝穴(21)が形成され、又、その目地板(2)の上面から前 記溝穴(21)の中心付近に渡って半円形或いはU字状の充填溝(22)が穿設され ている。更に目地板(2)の材質としてはゴム板或いはゴム系発泡体の抜きもの 、またはゴム板或いは発泡体の粉砕品を合成樹脂等で固めて成形したものを用い る。尚、ゴム系発泡体の発泡倍率は3〜20倍の範囲のものが良いが、7倍のも のが最良である。又、前記溝穴(21)の深さは接着層の厚みと成り、その大きさ は大きくなればなるほど接着面積が増加される。(3)は金属製或いは合成樹脂 製のインサ−トであり、これはブロック体(1)と目地板(2)を連結するもの である。 1 and 2 are diagrams showing an embodiment of the present invention, and description will be given based on these. (1) is a concrete boundary block body used for road construction or land boundary construction. (2) is a joint plate integrally provided on one end face of the block body (1). The joint plate (2) has the same shape as the end face of the block body (1) and has a thickness of about 15 mm. is there. Further, a circular or polygonal groove for adhering (21) having a depth of 0.5 mm to 2 mm is formed on the front end surface of the joint plate (2), and the upper surface of the joint plate (2) is also formed. Thus, a semicircular or U-shaped filling groove (22) is formed in the vicinity of the center of the groove hole (21). Further, as the material of the joint plate (2), a material obtained by removing a rubber plate or a rubber-based foam, or a product obtained by solidifying a crushed product of a rubber plate or a foam with a synthetic resin or the like is used. The expansion ratio of the rubber-based foam is preferably in the range of 3 to 20 times, but 7 times is the best. The depth of the groove (21) is the thickness of the adhesive layer, and the larger the size, the larger the adhesive area. (3) is an insert made of metal or synthetic resin, which connects the block body (1) and the joint plate (2).
【0007】 本考案品を製造する時には、先ず初めにインサ−ト(3)を目地板(2)用の 型にセットし、そこにゴム板或いは発泡体の粉砕品に合成樹脂等を混入したもの を入れて固めることにより、目地板(2)が成形されるのである。尚、ゴム板或 いはゴム系発泡体を抜いて成形した目地板(2)の場合には、インサ−ト(3) を取付ける穴や凹みが予め設けられており、そこへインサ−ト(3)を取付けれ ば良い。この時には、インサ−ト(3)の一部が目地板(2)の一端から突出さ れる。次に前記目地板(2)をコンクリ−ト境界ブロック用の型の所定位置にセ ットしてから、コンクリ−トを流し込むことにより、ブロック体(1)が成型さ れると同時に目地板(2)は前記インサ−ト(3)を介して一体に固着されるの である。When the product of the present invention is manufactured, first, the insert (3) is set in a mold for the joint plate (2), and a synthetic resin or the like is mixed therein with a rubber plate or a crushed product of foam. The joint plate (2) is molded by putting and hardening things. Incidentally, in the case of the joint plate (2) formed by removing the rubber plate or the rubber-based foam, a hole or a recess for mounting the insert (3) is provided in advance and the insert ( 3) should be attached. At this time, a part of the insert (3) is projected from one end of the joint plate (2). Next, by setting the joint plate (2) at a predetermined position of the mold for the concrete boundary block, and then pouring the concrete, the block body (1) is molded and at the same time, the joint plate ( 2) is integrally fixed via the insert (3).
【0008】 次に本考案品を用いて道路工事又は土地境界の施工を行う場合について説明す る。先ず目地板(2)が端面に設けられたブロック体(1)を用意し、それを所 定位置に順次配置させる。この時、目地板(2)がブロック体(1)間に必ず来 るように配置すると共に隙間が出来ないように押し付けて密着状態を確保しなが ら配列させる。その後、目地板(2)の上面の充填溝(22)位置から図3の矢印 のように接着剤を流し込む。すると、充填溝(22)の下方が溝穴(21)中心付近 まで達しているので、ここから接着剤が流れ込んで下方から順次充填でき、且つ 接着剤を多量に流し込んだ際であっても、溝穴(21)内部にある充填溝(22)の 横から接着剤が流れ出て充填出来るので、接着作業が素早く、且つ充填も確実に 行えるものとなる。その溝穴(21)が充填された後は、次の目地板(2)の充填 溝(22)から前記同様に接着剤を順次注入して行けば良い。このように本考案品 はブロック体(1)を並べる前に、該ブロック体(1)の端面に目地板(2)が 固着して定位置へ常に保持されるため、ブロック体(1)を単に並べるだけで、 従来のような目地板(2)のずれや外れがなくなるのである。またブロック体( 1)と目地板(2)の隙間も殆どない密着状態で接着して固定されるので、安定 した接着力を得ることが出来る。[0008] Next, a case where road construction or land boundary construction is performed using the product of the present invention will be described. First, a block body (1) having a joint plate (2) provided on the end face is prepared, and the block bodies (1) are sequentially arranged at predetermined positions. At this time, the joint plate (2) is arranged so as to always come between the block bodies (1), and the joint plates (2) are pressed against each other so that no gap is formed, and are arranged while ensuring a close contact. After that, the adhesive is poured from the position of the filling groove (22) on the upper surface of the joint plate (2) as shown by the arrow in FIG. Then, since the lower part of the filling groove (22) reaches near the center of the groove hole (21), the adhesive flows in from here and can be sequentially filled from below, and even when a large amount of the adhesive is poured, Since the adhesive flows out from the side of the filling groove (22) inside the groove (21) and can be filled, the bonding work can be performed quickly and the filling can be surely performed. After the groove hole (21) is filled, the adhesive may be sequentially injected from the filling groove (22) of the next joint plate (2) as described above. As described above, in the product of the present invention, before the block bodies (1) are arranged, the joint plate (2) is fixed to the end surface of the block body (1) and is always held in the fixed position. By simply arranging them, the displacement and disengagement of the conventional joint plate (2) can be eliminated. Further, since the block body (1) and the joint plate (2) are adhered and fixed in a close contact state with almost no gap, a stable adhesive force can be obtained.

本考案はこのように構成させたことにより、下記の効果を有する。 The present invention has the following effects by being configured in this way.
【0010】 請求項1に示すようにブロック体(1)の一端面には、これと同一形状の目地 板(2)がインサ−ト(3)を介して一体に設けられたこと、前記目地板(2) の表側端面の上方から溝穴(21)の中心付近に渡って充填溝(22)を穿設したこ とにより、ブロック体(1)に目地板(2)が固着されるので、ブロック体(1 )を並べる場合、単に押え付けながら並べるだけでブロック体(1)間が密着状 態となって配置でき、従来のようなブロック体(1)間の隙間の微調節作業が不 要となり、且つ目地板(2)の位置ずれ調節作業も不要となる。従って、本考案 品を用いてコンクリ−ト境界ブロックの施工を行えば、誰にでも簡単に、且つ素 早く行えるため施工費のコストダウンに寄与できる。しかもブロック体(1)と 目地板(2)の隙間も殆どない密着状態で接着して固定されるので、安定した接 着力を得ることが出来る。As described in claim 1, a joint plate (2) having the same shape as that of the block body (1) is integrally provided on one end surface of the block body (1) through an insert (3). Since the filling groove (22) is formed from above the front end surface of the main plate (2) to near the center of the slot (21), the joint plate (2) is fixed to the block body (1). When arranging the block bodies (1), the block bodies (1) can be arranged in a close contact state simply by arranging them while holding them down, and the fine adjustment work of the gap between the block bodies (1) as in the conventional case can be performed. It is unnecessary, and the work for adjusting the displacement of the joint plate (2) is also unnecessary. Therefore, if the concrete boundary block is constructed using the present invention, anyone can easily and quickly carry out the construction, which can contribute to the reduction of the construction cost. Moreover, since the block body (1) and the joint plate (2) are adhered and fixed in a close contact state with almost no gap, a stable adhesion force can be obtained.
【0011】 請求項2に示すように目地板(2)をゴム板或いはゴム系の発泡体で形成させ たことにより、ブロック体(1)間の目地板(2)は、気候条件の変化によるブ ロック体(1)自体の伸縮等で目地部の隙間に変動が生じても、目地板(2)に は弾力性を有しているので充分に追従でき、長期間に渡る気密性の確保が可能と なる。Since the joint plate (2) is formed of a rubber plate or a rubber-based foam as described in claim 2, the joint plate (2) between the block bodies (1) is changed due to a change in climatic conditions. Even if the joint gap changes due to expansion and contraction of the block body (1) itself, the joint plate (2) has elasticity so that it can sufficiently follow and ensure airtightness for a long period of time. Is possible.
【0012】 請求項3のように目地板(2)がゴム板又は発泡体の粉砕品を合成樹脂等で固 めて成形されることにより、耐摩耗性と耐候性が良好なものとなる。尚、前記ゴ ム板又は発泡体の粉砕品は産業廃棄物とならずに再利用できるので、資源の有効 利用に貢献できる。When the joint plate (2) is formed by solidifying a crushed product of a rubber plate or a foam with a synthetic resin or the like as in claim 3, wear resistance and weather resistance are improved. In addition, since the rubber plate or the crushed product of foam can be reused without becoming industrial waste, it can contribute to effective use of resources.
【0013】 請求項4のように充填溝(22)の形状を半円形或いはU字状に設けることによ り、接着剤の流し込みがスム−ズに行え、且つ接着剤が溝穴(2)を確実に充填 出来るものとなる。By providing the filling groove (22) in a semicircular shape or a U shape as described in claim 4, the adhesive can be poured smoothly and the adhesive can be provided in the groove hole (2). Can be reliably filled.
