Description

【考案の詳細な説明】[Detailed description of the device]

【0001】[0001]

【考案の属する技術分野】[Technical field to which the device belongs]

本考案はコンクリートのセグメント同志を接続するためのセグメント継手に関 する。 The present invention relates to a segment joint for connecting concrete segments to each other.

【0002】[0002]

【従来の技術】[Prior art]

コンクリートセグメントは円環体を放射状に幾つかに分断した形状をしており 、トンネルの内壁面を形成する場合、セグメントを円周方向に接続すると共に幅 の方向にも順次接続していく。 The concrete segment has a shape in which a torus is radially divided into several parts. When forming the inner wall surface of a tunnel, the segments are connected in the circumferential direction and also in the width direction.

【0003】 この接続にはボルト・ナットが使われるが、接続面に強大な締付力がかかるた め、継手金物が埋設されている。この継手金物の一面はセグメント表面に露出し 、他面はセグメント内に埋もれる。セグメント同志の接続の際、ボルトを両セグ メント間に挿通してナット締めするが、このボルトの挿通及びナットの締付けに は所要の空間がセグメントに用意されていなくてはならない。Bolts and nuts are used for this connection, but since a strong tightening force is applied to the connection surface, a joint metal fitting is embedded. One surface of this joint metal is exposed on the surface of the segment, and the other surface is buried in the segment. When connecting the segments to each other, insert bolts between both segments and tighten the nuts. The space required for inserting the bolts and tightening the nuts must be provided in the segments.

【0004】 従来の継手には接続板部の背面上部に短いひさしがついたものがあるが、コン クリートの打設時にコンクリートがひさしの下側にまわってしまうので、連結ボ ルト空間用型枠を設置してボルト・ナットによる締付け作業空間を作り出してい る。Some conventional joints have a short eaves on the upper back surface of the connecting plate portion, but since concrete turns around the eaves when the concrete is placed, the formwork for the connecting bolt space is formed. Is installed to create a work space for tightening with bolts and nuts.

【0005】[0005]

【考案が解決しようとする課題】[Problems to be solved by the device]

本考案は、この連結ボルト空間用型枠をコンクリートセグメント製造の都度設 置する工程を省略してもなおかつ必ずボルト・ナットの作業空間が確保できる、 セグメント継手を提供することを目的とする。 An object of the present invention is to provide a segment joint in which a work space for bolts and nuts can be secured without omitting the step of installing the connecting bolt space formwork each time a concrete segment is manufactured.

【0006】[0006]

【課題を解決するための手段】[Means for Solving the Problems]

本考案にかかるセグメント継手は接合板部とボックス部を有する。該接合板部 は連結用ボルトの挿通孔が貫通しかつその一面の側縁部にアンカー鉄筋螺合用の 雌ねじを有する。該ボックス部は該接合板部の該一面から該雌ねじを避けて連続 しかつ該接合板部側は開放している。 The segment joint according to the present invention has a joint plate portion and a box portion. The joint plate portion has an insertion hole for the connecting bolt penetrating therethrough, and has a female screw for screwing the anchor reinforcing bar on a side edge portion of one surface thereof. The box portion is continuous from the one surface of the joining plate portion while avoiding the female screw, and the joining plate portion side is open.

【0007】 また、本考案にかかる別のセグメント継手は接合板部とボックス部を有する。 該接合板部は連結用ボルトの挿通孔が貫通し、その一面に、ストッパー機能を有 する一対の溝と、該溝より外縁側のアンカー鉄筋螺合用の雌ねじを有する。該ボ ックス部は該接合板部の該一面との対向面及びこの対向面の一端でこの対向面と 直角をなす一面が開放し、該対向面の両側縁に該接合板部の溝と係合する突条を 備えている。そして、該突条と溝による該ボックス部と該接合板部との係合完了 状態で該ストッパー機能により接合板部の各端面と該ボックス部の一面とその対 向面がそれぞれ同一水準に位置する。Further, another segment joint according to the present invention has a joint plate portion and a box portion. The joint plate portion has an insertion hole for the connecting bolt penetrating therethrough, and has on one surface thereof a pair of grooves having a stopper function and a female screw for screwing the anchor reinforcing bar on the outer edge side of the groove. The box portion has a surface facing the one surface of the joining plate portion and one surface perpendicular to the facing surface at one end of the facing surface is open, and a groove of the joining plate portion engages with both side edges of the facing surface. It has ridges that fit together. Then, when the engagement between the box portion and the joining plate portion by the ridge and the groove is completed, each end surface of the joining plate portion, one surface of the box portion and its facing surface are positioned at the same level by the stopper function. To do.

【0008】 該ボックス部の該接合板部と反対側の壁体は該一面側での長さが対向面の長さ より大きい、傾斜面となっていてもよい。 該ストッパー機能は該溝と該突条による楔作用によりなされていてもよい。The wall body of the box portion opposite to the joint plate portion may be an inclined surface whose length on the one surface side is larger than the length of the facing surface. The stopper function may be performed by a wedge action of the groove and the protrusion.

【0009】[0009]

【課題を解決するための手段】[Means for Solving the Problems]

ボックス部の開放した側は型枠の底面に載せられ、接続板部の他面は型枠の側 面に取付けられる。 The open side of the box is placed on the bottom of the form, and the other side of the connecting plate is attached to the side of the form.

【0010】 雌ねじにはアンカー鉄筋が螺合される。コンクリートを型枠内の空間に打設す ると、型枠底面、ボックス部及び接合板部で囲まれた空間にはコンクリートが入 らず、製品となった状態でこの空間は製品の一面に開放する。An anchor rebar is screwed into the female screw. When concrete is poured into the space inside the formwork, concrete does not enter the space surrounded by the bottom of the formwork, the box part, and the joint plate part, and this space becomes a surface of the product when it is a product. Open.

【0011】 セグメント同志を対向させて継手同志を接合させ、ボルトを一方の製品の空間 に入れ、その継手の挿通孔から他方の継手の挿通し、他方の継手側の空間にナッ トを入れてこのボルトに螺合し、締付けて両セグメントを緊結する。Join the joints with the segments facing each other, insert the bolt into the space of one product, insert the other joint through the insertion hole of that joint, and insert the nut into the space of the other joint side. It is screwed onto this bolt and tightened to tighten both segments.

【0012】 本考案にかかる別の例の場合、ボックス部が接合板部と別個に造られる点が相 違している。両者は組合せて使用されるが、接合板部は一面にストッパー機能を 有する一対の溝を備えている。また、ボックス部は接合板部との対向面及びこの 対向面の一端でこの対向面と直角をなす一面が開放している。そしてこの対向面 の両側縁に接合板部の溝と係合する突条を備えている。Another example of the present invention is different in that the box portion is formed separately from the joining plate portion. Both are used in combination, but the joint plate part has a pair of grooves having a stopper function on one surface. Further, the box portion is open to a surface facing the joining plate portion and one surface perpendicular to the facing surface at one end of the facing surface. Then, on both side edges of this facing surface, there are provided ridges that engage with the grooves of the joint plate portion.

【0013】 ストッパー機能は接合板部とボックス部を所定の位置で一体化させるためのも ので、溝及び突条がそれぞれ平行の場合は溝の所定の位置にストッパーを形成し ておいてもよい。Since the stopper function is to integrate the joining plate portion and the box portion at a predetermined position, a stopper may be formed at a predetermined position of the groove when the groove and the protrusion are parallel to each other. .

【0014】[0014]

【考案の実施の形態】[Embodiment of device]

第一及び第二の考案の場合、該ボックス部の該接合板部と反対側の壁面は、該 開放口側での長さが該開放口との対向側の長さより大きい、傾斜面となっている と、緊結用ボルトを挿通孔に挿通する作業がし易くなる。 第二の考案の場合、該ストッパー機能は該溝と該突条による楔作用によりなさ れると、接合板部とボックス部が密接に一体化され、がたつきがなくなる。 In the case of the first and second inventions, the wall surface of the box portion on the side opposite to the joining plate portion is an inclined surface whose length on the opening side is larger than the length on the side facing the opening. This makes it easier to insert the tightening bolt into the insertion hole. In the case of the second invention, when the stopper function is performed by the wedge action of the groove and the ridge, the joining plate portion and the box portion are closely integrated and rattling is eliminated.

【実施例】【Example】

図面で、同一符号は同一もしくは相応部分を示す。 図1乃至図6で、1は接合板部、2はボックス部である。 接合板部1は連結用ボルト3の挿通孔11が貫通し、かつその一面12の側縁 部にアンカー鉄筋4を螺合するための雌ねじ13を有する。 In the drawings, the same reference numerals indicate the same or corresponding parts. 1 to 6, 1 is a joining plate portion, and 2 is a box portion. The joint plate portion 1 has an insertion hole 11 for the connecting bolt 3 penetrating therethrough, and has a female screw 13 for screwing the anchor rebar 4 into a side edge portion of one surface 12 thereof.

【0016】 ボックス部2は接合板部1の一面12から雌ねじ13を避けて連続し、かつ接 合板部1側は開放している。 この継手は通常のようにコンクリートセグメント5に埋設される。この場合、 ボックス部2、接合板部1及び型枠の底面で囲まれた空間にコンクリートは流れ 込まないので、型枠から外した製品の一面には空間6が露出する。The box portion 2 is continuous from the one surface 12 of the joining plate portion 1 avoiding the female screw 13, and the joining plate portion 1 side is open. This joint is normally embedded in the concrete segment 5. In this case, since concrete does not flow into the space surrounded by the box portion 2, the joining plate portion 1 and the bottom surface of the mold, the space 6 is exposed on one surface of the product removed from the mold.

【0017】 従って、セグメント5、5同志を対接し、連結用ボルト3を一方のセグメント 5の空間6に入れて挿通孔11、11に挿通し、他方のセグメント5の空間6に ナット7を入れてボルト3に螺合し、これを締付ければセグメント5、5同志が 緊結される。Therefore, the segments 5 and 5 are opposed to each other, the connecting bolt 3 is inserted into the space 6 of one segment 5 and inserted into the insertion holes 11 and 11, and the nut 7 is inserted into the space 6 of the other segment 5. By screwing it onto the bolt 3 and tightening it, the segments 5 and 5 will be tightly connected.

【0018】 図7乃至図12で、1は接合板部、2はボックス部である。 接合板部1は連結用ボルト3の挿通孔11が貫通し、その一面12に、ストッ パー機能を有する一対の溝15、15と、各溝より外縁側のアンカー鉄筋4用の 雌ねじ13を有する。In FIGS. 7 to 12, 1 is a joining plate portion, and 2 is a box portion. The joining plate portion 1 has an insertion hole 11 for the connecting bolt 3 penetrating therethrough, and has on one surface 12 thereof a pair of grooves 15 and 15 having a stopper function and an internal thread 13 for the anchor rebar 4 on the outer edge side of each groove. .

【0019】 ボックス部2は、接合板部1の一面12との対向面21及びこの対向面21の 一端でこの対向面21と直角をなす一面22が開放している。また、対向面21 の両側縁に接合板部1の溝15と係合する突条23を備えている。In the box portion 2, a surface 21 facing the one surface 12 of the joining plate portion 1 and a surface 22 perpendicular to the facing surface 21 at one end of the facing surface 21 are open. In addition, protrusions 23 that engage with the grooves 15 of the joint plate portion 1 are provided on both side edges of the facing surface 21.

【0020】 そして、突条23と溝15によるボックス部材2と接合板部1との係合完了状 態でストッパー機能により接合板部1の各端面16、17とボックス部2の一面 22とその対向面24がそれぞれ同一水準に位置する。Then, in a state where the box member 2 and the joining plate portion 1 are completely engaged with each other by the protrusions 23 and the grooves 15, each end surface 16 and 17 of the joining plate portion 1 and the one surface 22 of the box portion 2 are provided by a stopper function. The facing surfaces 24 are located at the same level.

【0021】 この継手はボックス部2を接合板部1にその突条23を溝15に係合させて一 体化する。そして第一の考案の場合と同様にセグメントに埋設される。セグメン ト同志の締着は第一の考案の場合と同様であるので、説明は省略する。 ボックス部2と接合板部1が別体なので、格納時等に嵩張らずに済む。In this joint, the box portion 2 is joined to the joining plate portion 1 and the projection 23 thereof is engaged with the groove 15 to be integrated. Then, it is embedded in the segment as in the case of the first invention. The fastening of the segment members is the same as in the case of the first device, and the description thereof will be omitted. Since the box portion 2 and the joining plate portion 1 are separate bodies, they do not need to be bulky when stored.

【0022】 ボックス部2の接合板部1と反対側の壁体25は、一面22での長さが対向面 24の長さより大きい傾斜面となっている。こうすると、連結用ボルト3を挿通 孔11、11に挿通する作業がし易くなる。 ストッパー機能は溝15と突条23による楔作用によりなされる。こうすると 、接合板部1とボックス部2が密接に一体化され、がたつきがなくなる。The wall body 25 of the box portion 2 on the side opposite to the joining plate portion 1 is an inclined surface whose one surface 22 is longer than the opposing surface 24. This makes it easier to insert the connecting bolt 3 into the insertion holes 11 and 11. The stopper function is performed by the wedge action of the groove 15 and the protrusion 23. By doing so, the joining plate portion 1 and the box portion 2 are closely integrated with each other and rattling is eliminated.

【0023】[0023]

【考案の効果】[Effect of device]

本考案は第一及び第二の考案共に、連結ボルト空間用型枠(ボックス部)を連 結板に一体化したので、型枠設置工程を省略でき、従って、セグメント製造工程 の短縮を図れ、このボックス部により連結用のボルト・ナットを収める空間を確 保できる。 In both the first and second inventions of the present invention, the connecting bolt space formwork (box part) is integrated with the connecting plate, so that the formwork installation step can be omitted and therefore the segment manufacturing process can be shortened. With this box part, you can secure a space to store the connecting bolts and nuts.

【0024】 請求項2の本件第二の考案によれば、上記の効果に加え、接続板部とボックス 部を分割して収納、運搬でき、取扱いが容易となる。According to the second invention of the second aspect of the present invention, in addition to the above effects, the connection plate portion and the box portion can be separately stored and transported, and the handling is facilitated.

【0025】 請求項3によれば、連結用ボルトを挿通孔に挿通する作業をし易くできる。 請求項4によれば、接合板部とボックス部が密接に一体化され、がたつきをな くせる。According to the third aspect, the work of inserting the connecting bolt into the insertion hole can be facilitated. According to the fourth aspect, the joint plate portion and the box portion are intimately integrated with each other to prevent rattling.
