Description
【０００１】[0001]
本考案は、止水を確保してコンクリートブロック相互を安定的に接合するコン クリートブロックの止水接合装置に関するものである。 The present invention relates to a concrete block water-stop joint device for securing water stoppage and stably joining concrete blocks to each other.
【０００２】[0002]
コンクリートブロック相互を止水を確保して接合する従来要領の一例としては 、ブロック接合面の当接部分に樹脂硬化物を形成するものがある。これを図１６ に基づいて説明すると、該コンクリートブロックａは、その接合面ｂの前側に位 置させて、長さ方向に凹溝ｃが設けられ、該凹溝ｃの両側には、弾性軟質止水材 ｄを嵌め込むための嵌込溝ｅが設けられ、又接合面ｂの後側には該接合面ｂに一 端が開口してブロックの長さ方向に延びるボルト挿入孔ｆが設けられ、該ボルト 挿入孔ｆの他端は、側面部に設けた接合用凹部ｇに開口していた。 As an example of a conventional procedure for joining concrete blocks to each other while securing water blocking, there is one in which a resin cured product is formed at the abutting portion of the block joining surface. This will be described with reference to FIG. 16. The concrete block a is provided on the front side of the joint surface b thereof and is provided with concave grooves c in the longitudinal direction, and both sides of the concave groove c are provided with elastic soft material. A fitting groove e for fitting the water blocking material d is provided, and a bolt insertion hole f whose one end opens at the joint surface b and extends in the length direction of the block is provided on the rear side of the joint surface b. The other end of the bolt insertion hole f was open to the joining recess g provided on the side surface.
【０００３】 該ブロック相互の接合に際しては、予め、一方の接合面の嵌込溝ｅの底部に弾 性軟質止水材ｄが貼着された。そして、両接合面ｂ，ｂを当接させて凹溝ｃ，ｃ の合致による充填孔ｈを形成し、且つ直線状に連通するボルト挿入孔ｆ，ｆにボ ルトｉを挿入してその両端部分のネジ部ｊ，ｊを前記接合用凹部ｇ，ｇ内に突出 させた。なお、ボルト挿入孔ｆへのボルトｉの挿入を容易に行うため、ボルト挿 入孔の径はボルトの径よりも稍大きめに形成していた。そしてネジ部ｊにナット ｋを螺合して締め付け、嵌込溝の合致によって形成された収容部ｍ内に弾性軟質 止水材ｄを圧縮状態に収容せしめ、その後接合用凹部ｇをモルタルｎで埋め、又 充填孔ｈには樹脂液を充填し、樹脂液の硬化物ｐによりブロックの接合部分ｑを 止水するものであった。When joining the blocks to each other, an elastic soft water blocking material d is previously attached to the bottom of the fitting groove e on one joining surface. Then, the joint surfaces b, b are brought into contact with each other to form the filling hole h by the matching of the concave grooves c, c, and the bolt i is inserted into the bolt insertion holes f, f communicating with each other in a straight line so that both ends thereof are inserted. The threaded portions j, j of the portions are projected into the recessed portions g, g for joining. In order to easily insert the bolt i into the bolt insertion hole f, the diameter of the bolt insertion hole is slightly larger than the diameter of the bolt. Then, the nut k is screwed into the screw portion j and tightened, and the elastic and soft water blocking material d is housed in a compressed state in the housing portion m formed by the matching of the fitting grooves, and then the joining concave portion g is formed by the mortar n. The filling or filling hole h was filled with a resin liquid, and the cured portion p of the resin liquid stopped the joint portion q of the block.
【０００４】[0004]
しかしかかる従来の接合要領によるときには、ボルトの周囲に隙間ｒが生じた ままであってブロックとボルトの一体性に乏しく、従ってブロックの接合部分ｑ が外力を受けてずれやすい問題があった。加えて、ボルトがボルト挿入孔内部で 動きやすいことからボルトが剪断補強材として有効に機能しなかったこと及びボ ルトは通常鋼製のものであって挿入孔に侵入した水によって腐食しやすかったこ とから、ブロック接合の信頼性に欠ける問題があった。かかる従来の接合におい て、もしも前記間隙ｒを充填剤で充填することを欲するならば、その充填のため に特別な工程が必要となって、施工に手間を要し又施工コストの上昇を招くこと となる。 本考案はかかる問題点を一挙に解決しうるコンクリートブロックの止水接合装 置の提供を目的とするものである。 However, according to the conventional joining method, there is a problem that the gap r remains around the bolt and the integrity of the block and the bolt is poor, so that the joining portion q 1 of the block is likely to be displaced by an external force. In addition, the bolt did not function effectively as a shear reinforcement material because it moved easily inside the bolt insertion hole, and the bolt was usually made of steel and easily corroded by water entering the insertion hole. Therefore, there is a problem that the reliability of the block bonding is lacking. In such a conventional joining, if it is desired to fill the gap r with a filler, a special process is required for the filling, which requires time and labor for construction and increases the construction cost. It will be. An object of the present invention is to provide a water-blocking joint device for concrete blocks that can solve all of these problems at once.
【０００５】[0005]
上記課題を解決するため本考案は次のような手段を採用する。 即ち本考案に係るコンクリートブロックの止水接合装置（以下止水接合装置と いう）１は、接合面１２に凹溝１５が設けられ、該凹溝１５に開口する直線状の 挿通孔２１が設けられてなるコンクリートブロック相互を、該挿通孔２１を挿通 する緊張棒材３を用いて接合する止水接合装置である。 In order to solve the above problems, the present invention employs the following means. That is, a watertight joining device for concrete blocks (hereinafter referred to as a watertight joining device) 1 according to the present invention is provided with a concave groove 15 on a joint surface 12 and a linear insertion hole 21 opening to the concave groove 15. The watertight joining apparatus joins the concrete blocks thus formed with each other by using the tension rods 3 that are inserted through the insertion holes 21.
【０００６】 該コンクリートブロックの接合面１２，１２が当接することにより、凹溝１５， １５が合致して所要長さの充填孔１３が形成され且つ挿通孔２１，２１が直線状 に連通する如くなされ、又該充填孔２１は注入口１８に連なる如くなされている 。When the joint surfaces 12, 12 of the concrete block come into contact with each other, the recessed grooves 15, 15 are aligned with each other to form the filling hole 13 having a required length, and the insertion holes 21, 21 communicate with each other in a linear manner. The filling hole 21 is formed so as to be continuous with the injection port 18.
【０００７】 そして係る構成を有するコンクリートブロック相互を、充填孔１３を遮断しない ように挿通孔２１に遊挿せしめられた前記緊張棒材３を用い、該緊張棒材を緊張 状態としてその両端部分をコンクリートブロックに固定することにより接合する ことを特徴とするものである。Then, the concrete rods having the above-mentioned configuration are used with the tension rods 3 inserted into the insertion holes 21 so as not to block the filling holes 13, and the tension rods are placed in a tensioned state so that both end portions thereof are tightened. It is characterized by being fixed by being fixed to a concrete block.
【０００８】 本考案に係る止水接合装置において、接合面１２に、弾性軟質止水材１６を嵌 め込むための嵌込溝１７を、凹溝１５を囲むように設けるのがよい。In the waterproof joint device according to the present invention, it is preferable that the joint surface 12 be provided with a fitting groove 17 for fitting the elastic and soft water blocking material 16 so as to surround the concave groove 15.
【０００９】[0009]
然してコンクリートブロック相互を接合するに際しては次のように行う。 即ち、接合面に嵌込溝１７が設けられている場合には、一方の接合面１２の嵌 込溝１７に弾性軟質止水材１６を貼着して後、凹溝１５，１５が向かい合うよう に接合面１２，１２を当接させて充填孔１３を形成し、且つ、凹溝に開口して連 通する挿通孔２１，２１に遊挿せしめられた緊張棒材３を用い、該緊張棒材を緊 張状態としてその両端部分をコンクリートブロックに固定することによりブロッ ク相互を接合し、嵌込溝１７，１７の合致によって形成された収容部１９内に弾 性軟質止水材１６を圧縮状態に収容させる。接合面間に弾性軟質止水材を介在さ せない場合には、図１５に示す如く、接合面当接部分４３の両端部分４７，４７ をライニング材４９によって塞ぐ。 However, when joining concrete blocks to each other, proceed as follows. That is, when the fitting groove 17 is provided on the joint surface, the elastic soft water stop material 16 is attached to the fitting groove 17 of the one joint surface 12, and then the concave grooves 15, 15 are opposed to each other. The tension rod 3 is formed by abutting the joining surfaces 12, 12 on the joint surface 12 to form the filling hole 13 and is loosely inserted into the insertion holes 21 and 21 which are opened in the groove and communicate with each other. The blocks are joined to each other by fixing both ends to a concrete block in a tensioned state, and the elastic soft water stop material 16 is compressed into the accommodating portion 19 formed by the mating of the fitting grooves 17 and 17. To be accommodated in the state. When the elastic and soft waterproof material is not interposed between the joint surfaces, both end portions 47, 47 of the joint surface abutting portion 43 are closed by the lining material 49 as shown in FIG.
【００１０】 然る後、注入口１８より充填孔１３に、液状充填剤（硬化によって止水機能を 発揮する樹脂液やグラウト等）を充填するのであるが、この注入の際、充填孔１ ３は圧縮状態の弾性軟質止水材１６によって囲まれた状態にあり、あるいはライ ニング材４９によって接合面当接部４３の両端部分４７，４７が塞がれているた め、充填孔１３から接合面当接部４３（図９）に液状充填剤が侵入したとしても 、これが外部に漏出する恐れはない。そのため注入された液状充填剤は、充填孔 １３を満たしつつその一部は挿通孔２１に流入し、緊張棒材３の周囲の間隙４４ も液状充填剤で充填されることとなる。After that, a liquid filler (resin liquid or grout exhibiting a water blocking function by curing) is filled into the filling hole 13 through the filling port 18. During the filling, the filling hole 13 is filled. Is surrounded by the elastic soft water stop material 16 in a compressed state, or both end portions 47, 47 of the joint surface abutting portion 43 are closed by the lining material 49. Even if the liquid filler enters the surface contact portion 43 (FIG. 9), there is no possibility that it will leak to the outside. Therefore, the injected liquid filler partially flows into the insertion hole 21 while filling the filling hole 13, and the gap 44 around the tension rod 3 is also filled with the liquid filler.
【００１１】 液状充填剤の硬化によって形成された充填孔部分における硬化物４２（図９） は止水作用を発揮する。又挿通孔における硬化物４５（図１）は、緊張棒材周囲 の隙間４４を埋めて緊張棒材とブロックを一体化させることから、緊張棒材３は 剪断補強材として設計通り有効に機能する。又挿通孔における硬化物４５は緊張 棒材３を被覆し、緊張棒材を防錆する。The hardened material 42 (FIG. 9) in the filling hole portion formed by hardening the liquid filler exhibits a water blocking effect. Further, the hardened material 45 (FIG. 1) in the insertion hole fills the gap 44 around the tension rod material to integrate the tension rod material and the block, so that the tension rod material 3 effectively functions as a shear reinforcement material as designed. . Further, the cured product 45 in the insertion hole covers the tension rod 3 to prevent the tension rod 3 from rusting.

【００１３】 該コンクリートブロック２は、例えば図３に示す如き、浄化槽を構築するため の立壁ブロックとして形成されており、上下方向に長い立壁部５下端に、つま先 部分６とかかと部分７を具える台座部９が設けられ、又立壁部５の内面には、水 平板１０の端部を受ける受部１１が突設されている。The concrete block 2 is formed as a standing wall block for constructing a septic tank, for example, as shown in FIG. 3, and has a toe portion 6 and a heel portion 7 at the lower end of the standing wall portion 5 which is long in the vertical direction. A pedestal portion 9 is provided, and a receiving portion 11 that receives the end portion of the horizontal plate 10 is provided on the inner surface of the standing wall portion 5 so as to project.
【００１４】 又ブロック両端の接合面１２，１２には、図４〜６に示す如く、上方に開口し 下方に直線状に延びて台座部９の下端近傍に至る充填孔１３を該接合面１２，１ ２相互が当接した状態において形成する（図４）、例えば半円弧状をなす凹溝１ ５，１５が、上下連続して設けられている。又該接合面１２には、例えばブチル ゴムからなる弾性軟質止水材１６を嵌込むための台形状をなす嵌込溝１７を、凹 溝１５をその上端を除いてＵ字状に囲むように設けてなり、接合面相互が当接し たとき、弾性軟質止水材１６を圧縮状態に収容させる収容部１９が対応嵌込溝１ ７，１７の合致によって形成される。なお図６において、説明の便宜上、弾性軟 質止水材１６は密集状態に点を付して表している。Further, as shown in FIGS. 4 to 6, the joint surfaces 12 and 12 at both ends of the block are provided with a filling hole 13 that opens upward and extends linearly downward to reach the vicinity of the lower end of the pedestal portion 9. , 12 are formed in a state where they are in contact with each other (FIG. 4), for example, recessed grooves 15, 15 in the shape of a semicircle are provided continuously in the vertical direction. Further, a trapezoidal fitting groove 17 for fitting an elastic and soft waterproof material 16 made of, for example, butyl rubber, is formed in the joint surface 12 so as to surround the concave groove 15 in a U shape except for the upper end thereof. When the joining surfaces are brought into contact with each other, the accommodating portion 19 for accommodating the elastic and soft water blocking material 16 in a compressed state is formed by the mating of the corresponding fitting grooves 17 and 17. Note that, in FIG. 6, for convenience of explanation, the elastic and soft water blocking material 16 is shown in a dense state with dots.
【００１５】 又ブロック一端の凹溝１５には、図３、図６に示す如く、その下端側の部分に おいて、一端がつま先部分６の表面に開口し且つ他端が凹溝１５に開口１８する 注入孔２０が連設されている。As shown in FIGS. 3 and 6, in the groove 15 at one end of the block, one end is opened on the surface of the toe portion 6 and the other end is opened at the groove 15 at the lower end side thereof. An injection hole 20 is provided in series.
【００１６】 又凹溝１５の上下方向の所要部位には、図１、図５〜６に示す如く、凹溝１５ に開口して立壁部の幅方向に直線状に延びる挿通孔２１が設けられており、接合 面相互が当接したとき、該挿通孔２１，２１は直線状に連通する。本実施例にお いて該挿通孔２１は、前記緊張棒材３の全体を挿入させうる長さに形成されてお り且つ該挿通孔２１の略中央部分にはブロックの内面側の表面部を凹ませること によって、開口端側程拡張する角錐台状の接合用凹部２２が形成されている。As shown in FIGS. 1 and 5 to 6, an insertion hole 21 that opens in the groove 15 and extends linearly in the width direction of the standing wall portion is provided at a required portion of the groove 15 in the vertical direction. Therefore, when the joining surfaces come into contact with each other, the insertion holes 21 and 21 communicate with each other linearly. In this embodiment, the insertion hole 21 is formed to have a length that allows the entire tension rod member 3 to be inserted therein, and a surface portion on the inner surface side of the block is formed at a substantially central portion of the insertion hole 21. By making the recess, a truncated pyramid-shaped recess 22 for joining is formed that expands toward the opening end side.
【００１７】 前記緊張棒材３は、図１〜２に示す如く、充填孔１３の直径よりも稍小径の丸 棒材として形成され、その両端部分は雄ネジ部２３，２３とされており、挿通孔 ２１に遊挿可能である。そして、接合用凹部２２内に突出する雄ネジ部２３に、 接合用凹部２２の傾斜壁面２４と裏面２５が当接し且つ表面２６が挿通孔の軸線 と直角をなす当接面を形成する座金２９を嵌めて後、ナット３０を螺合させこれ を締め付けることによりブロック相互を接合可能とされている（図１〜２）。な お該座金２９には、挿通孔２１に連通する孔３２が形成されている。As shown in FIGS. 1 and 2, the tension rod member 3 is formed as a round rod member having a diameter slightly smaller than the diameter of the filling hole 13, and both end portions thereof are male screw portions 23, 23. It can be freely inserted into the insertion hole 21. Then, a washer 29 is formed so that the inclined wall surface 24 and the back surface 25 of the joining concave portion 22 come into contact with the male screw portion 23 protruding into the joining concave portion 22 and the front surface 26 forms an abutting surface that is perpendicular to the axis of the insertion hole. After fitting, the nut 30 is screwed and the nuts are tightened, so that the blocks can be joined to each other (FIGS. 1-2). A hole 32 communicating with the insertion hole 21 is formed in the washer 29.
【００１８】 又接合用凹部２２は、図１、図５に示す如く蓋部材３３によって閉蓋可能とな されている。該蓋部材３３は円板状をなし、その開口側の円形テーパ周面３５に 設けたネジ溝３６と螺合するネジ部３７を周面に有し且つ周縁に偏らせて透孔３ ９を有し、閉蓋状態においては、図３、図８に示す如く、蓋部材外面が立壁部の 外面と面一となり且つ透孔３９が上位置に存するようになされている。Further, the joint recess 22 can be closed by a cover member 33 as shown in FIGS. The lid member 33 has a disk shape, and has a threaded portion 37 that is screwed into a thread groove 36 provided on a circular tapered circumferential surface 35 on the opening side of the lid member 33 on the circumferential surface and is biased to the peripheral edge to form a through hole 39. In the closed state, as shown in FIGS. 3 and 8, the outer surface of the lid member is flush with the outer surface of the standing wall portion, and the through hole 39 is in the upper position.
【００１９】 然して、係る構成を有するコンクリートブロック２，２相互を接合する要領は 次のようである。即ち図７に示すように、予め、何れか一方の接合面例えば右側 の接合面１２に形成された嵌込溝１７の底部に弾性軟質止水材１６を貼着してお き、又何れか一方のブロックの挿通孔例えば左側のブロックの挿通孔２１に緊張 棒材３を完全に挿入しておく。その後、両接合面の凹溝１５，１５が合致するよ うに接合面１２，１２を当接させて後、緊張棒材３を接合面１２より突出させ、 これを連通状態にある他方の挿通孔２１内に挿入させて雄ネジ部２３，２３を接 合用凹部２２，２２内に突出させる（図１）。However, the procedure for joining the concrete blocks 2 and 2 having such a configuration to each other is as follows. That is, as shown in FIG. 7, the elastic and soft water blocking material 16 may be attached in advance to the bottom of the fitting groove 17 formed in either one of the joint surfaces, for example, the right joint surface 12, or any one of them. The tension rod 3 is completely inserted into the insertion hole of one block, for example, the insertion hole 21 of the left block. After that, the joining surfaces 12 and 12 are brought into contact with each other so that the concave grooves 15 and 15 of both joining surfaces are aligned with each other, and then the tension rod 3 is projected from the joining surface 12, and this is inserted into the other insertion hole in the communicating state. The male screw portions 23, 23 are inserted into the protrusion 21, and the male screw portions 23, 23 are projected into the recesses 22, 22 for connection (FIG. 1).
【００２０】 その後、雄ネジ部２３に前記座金２９を嵌めてナット３０を締め付けると、緊 張棒材３を介してブロック２，２相互が接合され、弾性軟質止水材１６は、両嵌 込溝１７，１７の合致によって形成された収容部１９内に圧縮状態で収容される 。然る後、接合用凹部２２を蓋部材３３のねじ込みによって閉蓋し（図１）、前 記注入孔２０より液状充填剤（硬化によって止水機能を発揮する樹脂液やグラウ ト等）を充填する。After that, when the washer 29 is fitted into the male screw portion 23 and the nut 30 is tightened, the blocks 2 and 2 are joined to each other through the elastic rod member 3, and the elastic and soft water blocking material 16 is fitted in both sides. It is accommodated in a compressed state in the accommodating portion 19 formed by the matching of the grooves 17, 17. After that, the joining concave portion 22 is closed by screwing the lid member 33 (FIG. 1), and a liquid filler (resin liquid or grout exhibiting a water blocking function by curing) is filled through the injection hole 20. To do.
【００２１】 この充填の際、充填孔１３は、ブロック上端において開放するように、圧縮状態 の弾性軟質止水部材１６によって囲まれているため、注入された液状充填剤は、 外部への漏出が防止されて充填孔１３を満たしつつその一部は挿通孔２１内に流 入し、座金２９に設けた孔３２より接合用凹部２２内に流出する。その際透孔３ ９より内部の空気が排出され、該透孔３９から液状充填剤が流出したことを以て 、接合用凹部２２内が液状充填剤で充填されたことを確認できる（図８参照）。At the time of this filling, since the filling hole 13 is surrounded by the elastic soft water stop member 16 in a compressed state so as to be opened at the upper end of the block, the injected liquid filler does not leak to the outside. While being prevented and filling the filling hole 13, a part thereof flows into the insertion hole 21 and flows out into the joint recess 22 through the hole 32 provided in the washer 29. At that time, the air inside was discharged through the through hole 39, and the liquid filler flowed out through the through hole 39, so that it was possible to confirm that the joining recess 22 was filled with the liquid filler (see FIG. 8). .
【００２２】 この状態で、透孔３９を栓４０で塞ぐ（図３）。液状充填剤はこのようにして充 填孔１３を満たしていき、それが上端開放部（排気口）４１（図４）より流出し たことを以て、充填孔１３、各挿通孔２１、各接合用凹部２２が液状充填剤で充 填されたことを確認できる。In this state, the through hole 39 is closed with the plug 40 (FIG. 3). The liquid filler thus fills the filling hole 13 and flows out from the upper end opening portion (exhaust port) 41 (FIG. 4), so that the filling hole 13, each insertion hole 21, each joint It can be confirmed that the recess 22 is filled with the liquid filler.
【００２３】 液状充填剤の硬化によって形成された、図９に示す充填孔部分の硬化物４２は 、ブロックの接合面当接部４３を止水し、又図１に示す挿通孔部分の硬化物４５ は、緊張棒材３とブロック２とを一体化させる。The cured product 42 of the filling hole portion shown in FIG. 9 formed by curing the liquid filler stops the joint surface contact portion 43 of the block from water, and the cured product of the insertion hole portion shown in FIG. 45 integrates the tension rod 3 and the block 2.
【００２４】その他の実施態様 図１０は、凹溝１５に開口する挿通孔２１を、ブロック端部の接合用凹部２ ２まで延長し、直線状に連通する挿通孔２１，２１に緊張棒材（本実施例におい てはより線として形成されている）３を挿入し、該緊張棒材３を緊張状態として 後、その両端部分を固定具４４（座金４４ａと楔部材４４ｂと受筒部材４４ｃと からなる）を用いてブロック端部に固定した場合を示すものである。 Other Embodiments In FIG. 10, the insertion hole 21 that opens into the concave groove 15 is extended to the joining concave portion 22 at the end of the block, and the insertion holes 21 and 21 that linearly communicate with each other are provided with a tension rod material ( In the present embodiment, a stranded wire 3 is inserted and the tension rod 3 is placed in a tensioned state. Then, both ends of the tension rod 3 are fixed to a fixture 44 (a washer 44a, a wedge member 44b, a receiving cylinder member 44c). (A) is used for fixing to the end of the block.

本考案は以下の如き優れた効果を奏する。 本考案は、接合面に凹溝が設けられ、該凹溝に開口する直線状の挿通孔が設 けられてなるコンクリートブロック相互を、該挿通孔を挿通する緊張棒材を用い て接合する。そのため、接合面の当接によって形成された充填孔に液状充填剤を 注入すると、液状充填剤は充填孔を満たしつつその一部が挿通孔に流入し、緊張 棒材の周囲の間隙も液状充填材で充填された状態となる。 このようなことから、充填孔部分における硬化物によって、ブロック相互の接 合面当接部を確実に止水できる。 加えて、挿通孔における硬化物は、緊張棒材周囲の隙間を埋めて緊張棒材をブ ロックと一体化させる。従って、従来の如く緊張棒材の周囲に隙間が生ずる場合 とは異なり、ブロックの接合部分が外力を受けてずれるのを確実に防止できると ともに、緊張棒材を剪断補強材として設計通り有効に機能させうる。又挿通孔に おける硬化物は、緊張棒材を被覆して防錆機能を発揮する。このようなことから 、ブロック接合の信頼性が長期に亘って確保されることとなる。 The present invention has the following excellent effects. According to the present invention, concrete blocks each having a groove formed on the joint surface and a linear insertion hole opening to the groove are joined together by using a tension rod member inserted through the insertion hole. Therefore, when the liquid filler is injected into the filling hole formed by the contact of the joint surfaces, the liquid filler partially fills the insertion hole while filling the filling hole, and the gap around the tension rod is also filled with liquid. It becomes the state filled with the material. For this reason, the hardened material in the filling hole portion can surely stop the water from the abutting surface abutting portions of the blocks. In addition, the cured product in the insertion hole fills the gap around the tension rod material to integrate the tension rod material with the block. Therefore, unlike the conventional case where a gap is created around the tension rod material, it is possible to reliably prevent the joint portion of the block from being displaced by an external force, and at the same time effectively use the tension rod material as a shear reinforcement material as designed. It can function. Further, the hardened material in the insertion hole covers the tension rod material to exert a rust preventive function. As a result, the reliability of block joining can be ensured for a long period of time.
【００３３】 又本考案によるときには、充填孔に液状充填剤を注入することによって、挿 通孔及び接合用凹部にも同時に注入できることとなる。従って、図１６に示す従 来施工のように、充填孔への液状充填剤の注入工程、接合用凹部の埋め戻し工程 、特に接合用凹部の挿通孔を液状充填剤で充填する場合にはさらにこの充填工程 の三工程を別々に行わなければならない不都合がなく、これを一工程で達成でき 、施工能率の向上を期しうる。Further, according to the present invention, by injecting the liquid filler into the filling hole, it is possible to inject the liquid filler into the insertion hole and the joining recess at the same time. Therefore, as in the conventional construction shown in FIG. 16, when the step of injecting the liquid filler into the filling hole, the step of backfilling the joining recess, and especially the case of filling the insertion hole of the joining recess with the liquid filler, There is no inconvenience of having to perform the three steps of the filling step separately, and this can be achieved in one step, which can improve the construction efficiency.
