Description

本発明は、二つの部材を接合する継手、特に、二つの部材を接合面に平行乃至はやや傾斜した方向に動かして接合するのに適した継手部材、継手構造及びシールドセグメント用継手部材に関する。   The present invention relates to a joint for joining two members, and more particularly to a joint member, joint structure and joint member for shield segment suitable for jointing by moving two members in a direction parallel or slightly inclined to the joint surface.

特許文献１には、横板部材に径大挿入窓と長窓から成る挿入口を、縦板部材に軸部と鍔部から成る突出部を設けた部材の取付構造が記載されている。この取付構造では、鍔部を径大挿入窓から挿入した後、縦板部材を接合面に平行な方向に動かして、鍔部と長窓を係合させることによって縦板部材を横板部材に取り付ける（特許文献１の段落００１７、図３）。   Patent Document 1 describes a mounting structure of a member in which a horizontal plate member is provided with an insertion opening including a large diameter insertion window and a long window, and a vertical plate member is provided with a projection including a shaft portion and a collar portion. In this mounting structure, after the collar portion is inserted from the large diameter insertion window, the vertical plate member is moved in a direction parallel to the joint surface to engage the collar portion and the long window, thereby the vertical plate member to the horizontal plate member Attach (Paragraph 0017 of Patent Document 1, FIG. 3).

特許文献２には、第２黒鉛版にスライド係合溝を、第１黒鉛版にスライド係合溝に係合する係合突部をそれぞれ設けた焼成器具が記載されている。この焼成器具では、スライド係合溝の一端から係合突部を挿入し、接合面に平行な方向に部材をスライドさせて所定の位置に組み合わせ、スライド係合溝の方向に動かないようにピンで止める（特許文献２の００２２〜００２４、図２）。   Patent Document 2 describes a baking tool in which a slide engagement groove is provided on a second graphite plate, and an engagement protrusion is provided on the first graphite plate to be engaged with the slide engagement groove. In this baking apparatus, the engagement projection is inserted from one end of the slide engagement groove, and the member is slid in a direction parallel to the joint surface and assembled in a predetermined position so that the pin does not move in the direction of the slide engagement groove. Stop (see Patents 2 of 0022 to 0024, FIG. 2).

二つの部材を接合する方法として接合面に対して傾斜したボルトによる方法が知られている。例えば、特許文献３には、一方の部材に雌ねじを形成し、他方の部材にはボルトを貫通させる孔部とナットを固定するための空間を形成し、二つの部材をボルトにより結合する方法が記載されている（引用文献３の段落０００４、図１８）。   As a method of joining two members, a method using a bolt inclined to the joint surface is known. For example, in Patent Document 3, there is a method in which an internal thread is formed in one member, a hole for passing a bolt and a space for fixing a nut are formed in the other member, and two members are connected by the bolt. It is described (paragraph 0004 of cited reference 3 and FIG. 18).

特許文献４には、一方の部材にはメス型のコーンを、他方の部材にはオス型のコーンをそれぞれ設け、接合面に平行な方向に両部材を移動させてメス型のコーンとオス型のコーンを嵌合させる方法が記載されている（特許文献４の段落０００４、図６）。   According to Patent Document 4, a female cone is provided on one member, and a male cone is provided on the other member, and both members are moved in a direction parallel to the joint surface to obtain a female cone and a male. The method of fitting the cones of (1) has been described (paragraph 0004 of FIG. 4, FIG. 6).

特許文献１に記載の方法では、挿入口と突出部の形状が複雑で、接合する部材の材質によっては製作が困難であるという問題があった。また、接合する際に接合面と垂直方向に部材を動かすスペースがない場合に適用できないという問題があった。   The method described in Patent Document 1 has a problem that the shapes of the insertion port and the projecting portion are complicated, and it is difficult to manufacture depending on the material of the members to be joined. In addition, there is a problem that it can not be applied when there is no space for moving the member in the direction perpendicular to the bonding surface when bonding.

特許文献２に記載の方法では、接合面の全長に亘ってスライド係合溝が設けられているので、部材をスライドさせるために大きな空間がなければならないという問題があった。
また、部材の設置条件によっては、ピンを挿入することができないという問題があった。 In the method described in Patent Document 2, since the slide engagement groove is provided over the entire length of the joint surface, there is a problem that a large space is required to slide the member.
In addition, depending on the installation conditions of the members, there is a problem that the pins can not be inserted.

特許文献３に記載の傾斜したボルトによる継手では、二つの部材が正確に位置決めされた状態を維持しながらボルトの締結をしなければならず、施工が煩雑であるという問題があった。   In the inclined bolted joint described in Patent Document 3, it is necessary to fasten the bolt while maintaining the state in which the two members are accurately positioned, and there is a problem that the construction is complicated.

特許文献４に記載のメス型のコーンとオス型のコーンを組み合わせた継手を用いると、二つの部材の接合面を当接させた状態で接合面の方向にスライドさせることにより二つの部材を結合することができるため、傾斜したボルトを用いた場合に比べると施工性が良い。しかし、メス型のコーンとオス型のコーンという形状の異なる部品が必要となるため、製造コストや部品管理コストが大きくなるという問題があった。   When a joint in which a female cone and a male cone are combined as described in Patent Document 4 is used, the two members are joined by sliding them in the direction of the joint surface while the joint surfaces of the two members are in contact. Since it can be carried out, its workability is better than in the case where inclined bolts are used. However, there is a problem that the manufacturing cost and the part management cost become large because parts having different shapes such as a female cone and a male cone are required.

そこで、本発明では、組立性や施工性が良く安価な継手部材を提供することを目的とする。   So, in this invention, it aims at providing a cheap joint member which is good in assembling property and workability.

本発明の第１実施形態である継手部材１について説明する。図１は継手部材１の形状を説明する図であり、（Ａ）は正面図、（Ｂ）は左側面図、（Ｃ）は右側面図、（Ｄ）は平面図である。以後の説明を簡単にするため、図１（Ａ）の矢印で示したように、紙面の左右方向を挿入方向、紙面の上下方向を接合方向、紙面に垂直な方向を奥行き方向と呼ぶことにする。   A joint member 1 according to a first embodiment of the present invention will be described. FIG. 1 is a view for explaining the shape of the joint member 1, (A) is a front view, (B) is a left side view, (C) is a right side view, and (D) is a plan view. In order to simplify the following description, as indicated by the arrows in FIG. 1A, the horizontal direction of the paper is referred to as the insertion direction, the vertical direction of the paper is referred to as the joining direction, and the direction perpendicular to the paper is referred to as the depth direction. Do.

継手部材１は、他の継手部材と組み合わされて、被接合部材１００の接合面１０１と他の被接合部材の接合面を当接させた状態で接合するための継手を構成する。以下、本第１実施形態における他の継手部材は図示の継手部材１と略同一の構造であるとして説明する。   The joint member 1 is combined with another joint member to form a joint for joining in a state where the joint surface 101 of the joint member 100 and the joint surface of the other joint member are in contact with each other. Hereinafter, the other joint members in the first embodiment will be described as having substantially the same structure as the illustrated joint member 1.

継手部材１は、被接合部材１００の接合面１０１から接合方向負の向きに突出する突出部１０と、被接合部材１００に埋設される受部２０と、被接合部材１００に埋設され突出部１０と受部２０を接続する接続部３０を備えている。この実施形態では、継手部材１は鍛造によって形成されたものであり、突出部１０、受部２０、接続部３０は鍛造によって一体に形成されているが、鍛造以外の方法、例えば、鋳造や切削、三次元造形、放電加工、溶接による貼り合わせ等で形成することが可能である。   The joint member 1 is a protrusion 10 embedded in the member to be joined 100 and a protrusion 10 which protrudes from the joint surface 101 of the member to be joined 100 in the negative direction of the joint direction, the receiver 20 embedded in the member 100 to be joined And the connection part 30 which connects the receiving part 20 with each other. In this embodiment, the joint member 1 is formed by forging, and the projecting portion 10, the receiving portion 20, and the connecting portion 30 are integrally formed by forging, but methods other than forging, for example, casting or cutting It is possible to form by three-dimensional modeling, electric discharge machining, bonding by welding or the like.

突出部１０は、その全体が接合面１０１から突出している。即ち接合面１０１が突出１０と接続部３０との境界となっている。図１（Ｂ）、（Ｃ）に示すように、挿入方向に垂直な平面で切った場合の突出部１０の断面形状は上縁１２が下縁１１よりも小さい台形形状であり、この断面形状は挿入方向に一定である。端面１３と端面１４は挿入方向に対して垂直である。即ち、突出部１０の立体的な形状は、奥行き方向の幅が接合面に対向する側の端面から接合面側の端面に向かって漸次減少する一軸くさび形状である。なお、端面１３と端面１４は挿入方向に対して傾斜させたり、凹凸を設けたりしても良い。   The entire protrusion 10 protrudes from the bonding surface 101. That is, the joint surface 101 is the boundary between the protrusion 10 and the connection portion 30. As shown in FIGS. 1 (B) and 1 (C), the cross-sectional shape of the protrusion 10 when cut by a plane perpendicular to the insertion direction is a trapezoidal shape where the upper edge 12 is smaller than the lower edge 11, and this cross-sectional shape Is constant in the insertion direction. The end face 13 and the end face 14 are perpendicular to the insertion direction. That is, the three-dimensional shape of the protrusion 10 is a uniaxial wedge shape in which the width in the depth direction gradually decreases from the end face on the side opposite to the joining face to the end face on the joining face side. The end face 13 and the end face 14 may be inclined with respect to the insertion direction or may be provided with asperities.

受部２０は、接合方向の端面の一方の接合方向の位置が接合面１０１と一致するように被接合部材１００に埋設されている。受部２０は、二つの側壁２１と天部２２を備え、図１（Ａ）の右側の端面は開口部２３となっており、この開口部２３から他の継手部材の突出部を挿入可能となっている。そして、二つの側面２１、天部２２、開口部２３、開口部２３に対向する端面２４ａにより画定される空間は、開口部２３から挿入された他の継手部材の突出部を収容する収容部２４となっている。収容部２４の挿入方向に垂直な面で切った断面形状は、上縁２３ａの幅が突出部１０の下縁１１の幅と等しく、下縁２３ｂの幅が突出部１０の上縁１２の幅と等しい台形形状であり、この断面形状は挿入方向に一定である。また、収容部２４の挿入方向の長さは、突出部１０の同方向の長さとほぼ等しくなっている。即ち、収容部２４の形状は、他の継手部材の突出部の形状とほぼ同一であり、収容部２４は他の継手部材の突出部を完全に収容し得る。なお、受部２０の接合方向の端面の一方の接合方向の位置は接合面１０１と一致しないようにすることもできる。   The receiving portion 20 is embedded in the joined member 100 such that the position in one joining direction of the end face in the joining direction coincides with the joining surface 101. The receiving portion 20 is provided with two side walls 21 and a top portion 22, and the end face on the right side of FIG. 1A is an opening 23, from which the protrusion of another joint member can be inserted. It has become. A space defined by the two side surfaces 21, the top 22, the opening 23, and the end face 24 a facing the opening 23 is a housing 24 that accommodates the projections of other coupling members inserted from the opening 23. It has become. The cross-sectional shape of the accommodation portion 24 taken along a plane perpendicular to the insertion direction is such that the width of the upper edge 23a is equal to the width of the lower edge 11 of the projection 10 and the width of the lower edge 23b is the width of the upper edge 12 of the projection 10 And the cross-sectional shape is constant in the insertion direction. Further, the length in the insertion direction of the housing portion 24 is substantially equal to the length in the same direction of the protrusion 10. That is, the shape of the housing portion 24 is substantially the same as the shape of the projecting portion of the other joint member, and the housing portion 24 can completely accommodate the projecting portion of the other joint member. The position of one of the end faces in the joining direction of the receiving portion 20 in the joining direction may not coincide with the joining surface 101.

受部２０に他の継手部材の突出部が挿入された状態で、接合面に引張力が作用した場合には、他の継手部材の突出部は二枚の側板２１を押し広げて抜け出そうとするが、側板２１は自身の剛性の他、収容部２４の端面２４ａと天部２２によって支持されると共に、被接続部材１００により拘束されているので、抜け出すことができない。勿論、側板２１は肉厚を厚くして強度向上させるという方法以外に、側板２１の外側にリブやフランジ等の補強手段を設けて増強することで、側板２１が内側から押し広げられることを防止するように構成してもよい。   In a state where the projection of another joint member is inserted into the receiving portion 20, when a tensile force acts on the joint surface, the projection of the other joint member pushes the two side plates 21 apart and tries to break out However, the side plate 21 is supported by the end face 24a of the housing portion 24 and the top 22 in addition to its own rigidity, and is restrained by the connected member 100, so it can not be removed. Of course, the side plate 21 is reinforced by providing reinforcing means such as ribs and flanges on the outside of the side plate 21 other than the method of increasing the thickness and enhancing the strength, thereby preventing the side plate 21 from being pushed out from the inside It may be configured to

接続部３０は略直方体状の部材で、被接合部材１００に埋設されているが、勿論これには限定されていない。接続部３０の挿入方向の一方の端面３１には受部２０が、接合方向の一方の端面３２には突出部１０が接続されている。突出部１０の端面１４と収容部２４端面２４ａの挿入方向の位置は、接続部３０の端面３１と一致する位置関係になっている。この例では、接続部３０の形状を、製造を容易にするために直方体としているが、突出部１０と受部２０を概ね上記のような位置関係で接続し、また、接合時に他の継手部材の突出部により押圧される際の荷重に耐えることができれば、他の形状としてもよい。   Although the connection part 30 is a substantially rectangular parallelepiped member and is embedded in the to-be-joined member 100, of course, it is not limited to this. The receiving portion 20 is connected to one end surface 31 of the connecting portion 30 in the insertion direction, and the projecting portion 10 is connected to one end surface 32 of the connecting direction. The position in the insertion direction of the end surface 14 of the protrusion 10 and the end surface 24 a of the accommodation portion 24 is in a positional relationship that matches the end surface 31 of the connection portion 30. In this example, the shape of the connecting portion 30 is a rectangular solid to facilitate manufacture, but the projecting portion 10 and the receiving portion 20 are generally connected in the positional relationship as described above, and another joint member is used at the time of joining Other shapes may be used as long as they can withstand the load when pressed by the projection of the.

図２は、第１実施形態の変形例を示す図で、突出部１０と収容部２３の形状を一軸くさび形状以外の形状とした例である。突出部１０の断面形状を段差部１５を有する形状とし、収容部２４の断面形状を突出部１０と同型状としている。他の継手部材の突出部の段差部と収容部２４の段差部２６が係合するため、受部２０は他の継手部材の突出部が接合面から接合方向に抜け出さないように保持することができる。受部２０の形状は、他の継手部材の突出部を接合方向に動かないように係合することができれば、図１、２に示した形状とは異なるものとすることもできる。また、この条件を満たせば、他の継手部材の突出部と収容部２４の形状は同一でなくても良い。   FIG. 2 is a view showing a modified example of the first embodiment, and is an example in which the shapes of the projecting portion 10 and the housing portion 23 are shapes other than the uniaxial wedge shape. The cross-sectional shape of the projecting portion 10 is a shape having the step portion 15, and the cross-sectional shape of the housing portion 24 is the same shape as the projecting portion 10. Since the step portion of the projection of the other joint member engages with the step portion 26 of the accommodation portion 24, the receiving portion 20 can be held so that the projection of the other joint member does not come out of the joining surface in the joining direction it can. The shape of the receiving portion 20 may be different from the shape shown in FIGS. 1 and 2 as long as the protrusions of the other joint members can be engaged so as not to move in the joining direction. Moreover, as long as this condition is satisfied, the shapes of the projecting portion of the other joint member and the housing portion 24 may not be the same.

図３は、第１実施形態の他の変形例を示す図である。継手部材１の突出部１０と接続部３０の形状は図１に示したものと同一であるが、受部２０の側壁２７を三角形形状とし、開口部２８を接合面１０１に対して傾斜させている。これは、側壁２７を支持する天部２２及び接続部３０から離れているため側壁２７の強度には余り寄与しない部分２８ａを省略して材料の節約を図ったものである。このように、開口部は接合面に対して傾斜していても良く、また、収容部２４の形状を突出部１０を完全には収容しない形状としても良い。また、逆に突出部１０を収容部２４よりも小さくし、収容部２４に空間が残るようにしても良い。   FIG. 3 is a view showing another modified example of the first embodiment. The shapes of the projecting portion 10 and the connecting portion 30 of the joint member 1 are the same as those shown in FIG. 1, but the side wall 27 of the receiving portion 20 is triangular and the opening 28 is inclined with respect to the joining surface 101 There is. This is intended to save the material by omitting the portion 28a which does not contribute much to the strength of the side wall 27 because it is far from the top 22 supporting the side wall 27 and the connecting portion 30. As described above, the opening may be inclined with respect to the bonding surface, and the shape of the accommodation portion 24 may be a shape that does not completely accommodate the protrusion 10. Also, conversely, the protrusion 10 may be smaller than the housing 24 so that a space remains in the housing 24.

継手部材１の材料は、所望の強度、製造コスト、被接続部材１００が使用される環境条件等に応じて種々のものを使用することができ、勿論、継手部材１は金属の他、合成樹脂、木、紙、ガラス、セラミックス、ゴム或いはこれらの複合材料など適宜の材料を用いて適宜の製造方法で形成することが可能である。   Various materials can be used as the material of the joint member 1 according to the desired strength, manufacturing cost, the environmental conditions in which the connected member 100 is used, etc. Of course, the joint member 1 is not only metal but also synthetic resin It is possible to form by an appropriate manufacturing method using an appropriate material such as wood, paper, glass, ceramics, rubber or a composite material of these.

製造コストの観点からは、他の継手部材は継手部材１と同一の形状であることが望ましいが、接続部品１と機能的に同等の突出部、受部、連結部とを備え、他の継手部材の受部は、接合面と略平行な方向から継手部材１の突出部１０を挿入可能な開口部と、挿入された突出部１０を接合面から接合方向に抜け出さないように保持できる形状の収容部とを備えていれば、形状が異なっていてもよい。また、他の継手部材と継手部材１は素材が異なっていても良い。   From the viewpoint of manufacturing cost, it is preferable that the other joint members have the same shape as the joint member 1, but it has a projection, a receiving portion, and a connecting portion functionally equivalent to the connection part 1; The receiving portion of the member is shaped to be able to hold the opening into which the protrusion 10 of the joint member 1 can be inserted from the direction substantially parallel to the bonding surface and the inserted protrusion 10 not to be pulled out from the bonding surface in the bonding direction. The shape may be different as long as the housing portion is provided. In addition, the materials of the other joint members and the joint member 1 may be different.

次に、図４を参照して継手部材１を用いた部材の接合方法について説明する。図４では、既設の部材である被接合部材１００ａに対して被接合部材１００ｂを接合することを想定している。被接合部材１００ａには図１の継手部材１と同形状の継手部材１ａが、被接続部材１００ｂには図１の継手部材１と同形状の継手部材１ｂがそれぞれ固定されている。継手部材１ａの突出部１０ａは接合面１０１ａから、継手部材１ｂの突出部１０ｂは接合面１０１ｂから、それぞれ突出している。   Next, referring to FIG. 4, a method of joining members using the joint member 1 will be described. In FIG. 4, it is assumed that the member to be joined 100b is joined to the member to be joined 100a which is an existing member. The joint member 1a of the same shape as the joint member 1 of FIG. 1 is fixed to the member to be joined 100a, and the joint member 1b of the same shape as the joint member 1 of FIG. 1 is fixed to the member to be connected 100b. The protrusion 10a of the joint member 1a protrudes from the joint surface 101a, and the protrusion 10b of the joint member 1b protrudes from the joint surface 101b.

また、被接合部材１００ａの継手部材１ａに挿入方向に隣接する位置には空間１０２ａが、被接合部材１００ｂの継手部材１ｂに挿入方向に隣接する位置には空間１０２ｂが、それぞれ設けられている。この空間１０２ａ、１０２ｂは突出部１０ｂ、１０ａを収容でき、接合面１０１ａ、１０１ｂから突出部１０ｂ、１０ａを接合方向に挿入できる形状とする。   Further, a space 102a is provided at a position adjacent to the joint member 1a of the joined member 100a in the insertion direction, and a space 102b is provided at a position adjacent to the joint member 1b of the joined member 100b in the insertion direction. The spaces 102a and 102b can accommodate the protrusions 10b and 10a, and can be inserted in the bonding direction from the bonding surfaces 101a and 101b.

まず、図４（Ａ）に示すように、被接合部材１００ｂを接合面１０１ｂが被接合部１０１ａと対向し、突出部１０ｂと空間１０２ａの挿入方向の位置が一致するように被接合部材１００ａの近傍に配置する。   First, as shown in FIG. 4A, the bonding surface 101b of the bonding member 100b faces the bonding portion 101a, and the positions of the protrusion 10b and the space 102a in the insertion direction coincide with each other. Place in the vicinity.

この状態から、図４（Ａ）の矢印Ａのように、被接合部材１００ｂを被接合部材１００ａの方向に移動させ、接合面１００ａと接合面１００ｂを当接させ、図４（Ｂ）に示す状態とする。突出部１０ａは空間１０２ｂに、突出部１０ｂは空間１０２ａにそれぞれ収容されている。   From this state, as shown by arrow A in FIG. 4A, the member to be joined 100b is moved in the direction of the member to be joined 100a to bring the joining surface 100a into contact with the joining surface 100b, as shown in FIG. It will be in the state. The protrusion 10a is accommodated in the space 102b, and the protrusion 10b is accommodated in the space 102a.

次に、接合面１０１ａと接合面１０１ｂを当接させた状態で、被接合部材１００ｂを図４（Ｂ）の矢印Ｂの方向に移動させ、図４（Ｃ）に示すように突出部１０ｂが受部２０ａに、突出部１０ａが受部２０ｂにそれぞれ収容されるようにする。前述のように、受部２０ａ（２０ｂ）は、突出部１０ｂ（１０ａ）が接合方向に抜け出さないように保持できる形状となっているので、継手部材１ａは他の継手部材１ｂと組み合わされて継手７を構成することができる。   Next, in a state where the bonding surface 101a and the bonding surface 101b are in contact with each other, the member to be bonded 100b is moved in the direction of arrow B in FIG. 4 (B), and as shown in FIG. 4 (C) In the receiving portion 20a, the projecting portion 10a is accommodated in the receiving portion 20b. As described above, since the receiving portion 20a (20b) has a shape capable of holding the projecting portion 10b (10a) so as not to be pulled out in the joining direction, the joint member 1a is combined with another joint member 1b 7 can be configured.

図５は、接合面が挿入方向に対してやや傾斜している場合の継手部材１による部材の接合方法の一例を説明する図である。図５では、既設の被接合部材１００ｃ、１００ｄの間に被接合部材１００ｅをはめ込むことを想定している。各被接合部材の接合面１０３ｃ、１０３ｄ、１０３ｅは挿入方向に対して角度αだけ傾斜している。具体的な例としては、シールド工法に使用するリング部材を形成する際の、周方向に接合済のセグメント群に対して最後のセグメントを接合してリング部材を完成させる工程を挙げることができる。   FIG. 5 is a view for explaining an example of a method of joining members by the joint member 1 when the joining surface is slightly inclined with respect to the insertion direction. In FIG. 5, it is assumed that the member to be joined 100e is fitted between the existing members to be joined 100c and 100d. The bonding surfaces 103c, 103d, and 103e of the respective members to be bonded are inclined at an angle α with respect to the insertion direction. As a specific example, the process of joining the last segment with respect to the segment group joined in the circumferential direction at the time of forming the ring member used for a shield construction method can be mentioned, and a ring member is completed.

被接続部材１００ｃには継手部材１ｃが、被接続部材１００ｄには継手部材１ｄが、被接続部材１００ｅには二個の継手部材１ｅが、それぞれ固定されている。継手部材１ｃ、１ｄ、１ｅの形状は図１に示した継手部材１の形状と基本的には同一である。ただし、図５（Ｂ）に示すように、収容部２０ｃ、２０ｄ、２０ｅの接合面側の端面２９ｃ、２９ｄ、２９ｅを、接合面の挿入方向に対する傾斜αに合わせて傾斜させている。   The joint member 1c is fixed to the connected member 100c, the joint member 1d is fixed to the connected member 100d, and the two joint members 1e are fixed to the connected member 100e. The shapes of the joint members 1c, 1d and 1e are basically the same as the shape of the joint member 1 shown in FIG. However, as shown in FIG. 5B, the end faces 29c, 29d, 29e on the joint surface side of the housing portions 20c, 20d, 20e are inclined in accordance with the inclination α with respect to the insertion direction of the joint surface.

被接続部材１００ｃと被接合部材１００ｄの間隙の形状は、被接合部材１００ｅがちょうど嵌め込める形状となっているため、被接合部材１００ｅを接合方向には僅かしか動かすことができない。そのため、まず、被接合部材１００ｅを、被接合部材１００ｃ、１００ｄに対して奥行き方向にずらし、二つの突出部１０ｅと空間１０２ｃ、１０２ｄの挿入方向の位置が一致するように配置する。次に、被接合部材１００ｅを奥行き方向に移動して突出部１０ｅが空間１０２ｃ、１０２ｄに収容されるようにし、図５（Ａ）の状態とする。このように、被接合部材１００ｅを奥行き方向に移動させる必要があるため、空間１０２ｃ、１０２ｄ、１０２ｅは、図５（Ｄ）に示すように被接合部材１００ｅが挿入される方向が開口している必要がある。   The shape of the gap between the connected member 100c and the member to be joined 100d is such a shape that the member to be joined 100e can be just fitted, so the member to be joined 100e can be moved only slightly in the joining direction. Therefore, first, the members to be joined 100e are shifted in the depth direction with respect to the members to be joined 100c and 100d, and the positions of the two protrusions 10e and the spaces 102c and 102d in the insertion direction are aligned. Next, the members to be joined 100e are moved in the depth direction so that the protrusions 10e are accommodated in the spaces 102c and 102d, and the state shown in FIG. 5A is obtained. Thus, since it is necessary to move the to-be-joined member 100e to a depth direction, as the space 102c, 102d, 102e is shown to FIG 5 (D), the direction where the to-be-joined member 100e is inserted is opened. There is a need.

次に、図５（Ａ）の矢印Ｃの方向に被接合部材１００ｅを移動して、図５（Ｃ）の状態とする。突出部１０ｅは受部２０ｃ、２０ｄに、突出部１０ｃ、１０ｄは二つの受部２０ｅにそれぞれ収容され、継手８が構成される。   Next, the member to be joined 100e is moved in the direction of the arrow C in FIG. 5 (A) to obtain the state of FIG. 5 (C). The projecting portion 10 e is accommodated in the receiving portions 20 c and 20 d, and the projecting portions 10 c and 10 d are accommodated in the two receiving portions 20 e, respectively, and the joint 8 is configured.

図６（Ａ）〜（Ｄ）は、接合面が挿入方向に対してやや傾斜している場合の継手部材１による部材の接合方法の他の例を説明する図である。基本的には図５に示した方法と同様であるから、図５と同様の構成要素には図５と同一の符号を付して説明を省略する。   FIGS. 6A to 6D are diagrams for explaining another example of the method for joining members by the joint member 1 when the joining surface is slightly inclined with respect to the insertion direction. Basically, the method is the same as the method shown in FIG. 5, so the same components as in FIG. 5 will be assigned the same reference numerals as in FIG.

図５の例では、空間１０２ｃ、１０２ｄ、１０２ｅの形状を、継手部材の突出部１０ｃ、１０ｄ、１０ｅよりやや大きい台形状としたが、図６の例では、空間１０５ｃ、１０５ｄ、１０５ｅの形状を挿入方向に長い三角形形状としている。このようにしたため、被接合部材１００ｅを図６（Ａ）に示す位置に配置することができ、図４の例と同様に矢印Ｄ方向に動かして図６（Ｃ）に示すように継手８を構成することができる。側壁２０ｃ、２０ｅ、２０ｄの端面は図６（Ｂ）に示すように部材の傾斜α似合わせて傾斜させている。   In the example of FIG. 5, the shape of the spaces 102c, 102d, 102e is a trapezoidal shape slightly larger than the protrusions 10c, 10d, 10e of the joint members, but in the example of FIG. 6, the shape of the spaces 105c, 105d, 105e is It has a long triangle shape in the insertion direction. Since it did in this way, the member 100e to be joined can be arrange | positioned in the position shown to FIG. 6 (A), it moves to the arrow D direction similarly to the example of FIG. 4, and as shown to FIG. It can be configured. The end faces of the side walls 20c, 20e and 20d are inclined in conformity with the inclination α of the member as shown in FIG. 6 (B).

図６の例では、被接合部材１００ｅを奥行き方向に動かす必要がないので、各被接合部材の配置の自由度が図５の例に比べて大きくなる。また、空間１０５ｃ、１０５ｄ、１０５ｅの形状は、図６（Ｄ）に示すように奥行き方向に開口していない溝状とすることができるため、接合後に空間１０５ｃ、１０５ｄ、１０５ｅが被接合部材の表面に現れない。   In the example of FIG. 6, since it is not necessary to move the to-be-joined member 100e to a depth direction, the freedom degree of arrangement | positioning of each to-be-joined member becomes large compared with the example of FIG. In addition, since the shapes of the spaces 105c, 105d, and 105e can be grooves which are not opened in the depth direction as shown in FIG. 6D, the spaces 105c, 105d, and 105e are members to be joined after bonding. It does not appear on the surface.

継手部材１によれば、受部２０は他の継手部材の突出部を挿入可能な開口部２３と、挿入された他の継手部材の突出部を収容し接合面から接合方向に抜け出さないように保持できる受部２０を備えている。そのため、二つの被接合部材の接合面を当接させて二つの被接合部材を挿入方向に相対的に移動させるだけで容易に接合することができる。   According to the joint member 1, the receiving portion 20 accommodates the opening 23 into which the projection of the other joint member can be inserted and the projection of the other joint member inserted and prevents the joint portion from coming out of the joint surface The receiving part 20 which can be hold | maintained is provided. Therefore, it can join easily only by making the joint surface of two to-be-joined members contact | abut, and relatively moving two to-be-joined members to an insertion direction.

継手部材１は突出部１０と受部２０を接続する接続部３０を備え、一体の部品として構成されている。そのため、被接続部材１００に容易に取り付けることができる。   The joint member 1 includes a connecting portion 30 that connects the projecting portion 10 and the receiving portion 20, and is configured as an integral part. Therefore, it can be easily attached to the connected member 100.

継手部材１によれば、突出部１０も他の継手部材の受部に挿入され接合面から抜け出さないように保持され、係合箇所が二つ形成される。そのため、強固な継手を形成することができる。   According to the joint member 1, the protrusion 10 is also inserted into the receiving portion of another joint member and held so as not to come out of the joint surface, and two engagement points are formed. Therefore, a strong joint can be formed.

継手部材１によれば、突出部１０と連結部３０は、接合面を跨いで配置されている。そのため、継手部材１の様に構成された継手は、接合方向に沿った引張力に抵抗するだけでなく、接合面に対する剪断力に抵抗することもできる。   According to the joint member 1, the protruding portion 10 and the connecting portion 30 are disposed across the joint surface. Therefore, the joint configured as the joint member 1 can not only resist the tensile force along the joint direction but also resist the shear force on the joint surface.

本発明の第２実施形態である継手部材２について説明する。図７は継手部材２の形状を説明する図であり、（Ａ）は正面図、（Ｂ）は左側面図、（Ｃ）は右側面図、（Ｄ）は平面図である。継手部材２は、突出部、受部、連結部を備え、他の継手部材と組み合わされて継手を構成する点では第１実施形態の継手部材１と同様であるが、各部の形状が異なっている。以下、他の継手部材は図示の継手部材２とほぼ同一の形状であるとして説明する。   A joint member 2 according to a second embodiment of the present invention will be described. FIG. 7 is a view for explaining the shape of the joint member 2, (A) is a front view, (B) is a left side view, (C) is a right side view, and (D) is a plan view. The joint member 2 is similar to the joint member 1 according to the first embodiment in that the joint member 2 includes a projection, a receiving portion, and a connecting portion and is combined with another joint member to form a joint, but the shape of each portion is different There is. The other joint members will be described below as having substantially the same shape as the illustrated joint member 2.

継手部材２は、被接合部材１００の接合面１０１から突出する突出部４０と、被接合部材１００に埋設される受部５０と、被接合部材１００に埋設され突出部４０と受部５０を接続する接続部６０を備えている。   The joint member 2 includes a protrusion 40 protruding from the joint surface 101 of the member 100 to be joined, a receiving portion 50 embedded in the member 100 to be joined, and a portion 40 embedded in the member 100 to be joined. The connection unit 60 is provided.

突出部４０は、その全体が接合面１０１から突出している。即ち接合面１０１が突出４０と接続部６０との境界となっている。図７（Ｂ）、（Ｃ）に示すように、挿入方向に垂直な平面で切った場合の突出部４０の断面形状は、端面４３においては接合面側の幅をｂ１、接合面に対向する側の幅をｂ２とするとき、これらの大小関係が次の不等式（１）を満たす台形である。
ｂ２＞ｂ１ 不等式（１）
挿入方向に垂直な平面で切った場合の突出部４０の断面形状は、端面４４においては接合面側の幅をｂ３、接合面に対向する側の幅をｂ４とするとき、これらの大小関係が次の不等式（２）を満たす台形となっている。
ｂ４＞ｂ３ 不等式（２）
また、挿入方向に関しては、ｂ１＜ｂ３、ｂ２＜ｂ４という大小関係になっている。即ち、突出部４０の立体的な形状は、接合方向の幅が奥行き方向に漸次減少すると共に、挿入方向にも漸次減少する二軸楔形状の構造を成す。 The projecting portion 40 entirely protrudes from the bonding surface 101. That is, the joint surface 101 is the boundary between the protrusion 40 and the connection portion 60. As shown in FIGS. 7B and 7C, the cross-sectional shape of the projecting portion 40 in the case of cutting by a plane perpendicular to the insertion direction has a width b1 on the bonding surface side at the end surface 43 and is opposed to the bonding surface When the width of the side is b2, the magnitude relation between them is a trapezoid satisfying the following inequality (1).
b2> b1 inequality (1)
The cross-sectional shape of the protrusion 40 when cut by a plane perpendicular to the insertion direction is the size relationship of the end surface 44 when the width on the bonding surface side is b3 and the width on the side facing the bonding surface is b4. The trapezoid satisfies the following inequality (2).
b4> b3 inequality (2)
Further, regarding the insertion direction, there is a magnitude relationship of b1 <b3 and b2 <b4. That is, the three-dimensional shape of the projecting portion 40 has a two-axis wedge-shaped structure in which the width in the joining direction gradually decreases in the depth direction and also gradually decreases in the insertion direction.

受部５０は、接合方向の端面の一方の接合方向の位置が接合面１０１と一致するように被接合部材１００に完全に埋設されている。受部５０は、二つの側壁５１と天部５２を備え、図７（Ａ）の右側の端面は開口部５３となっており、この開口部５３から他の継手部材の突出部を挿入可能となっている。そして、二つの側面５１、天部５２、開口部５３に対向する端面５４ａの内部の空間は、開口部５３から挿入された他の継手部材の突出部を収容する収容部５４となっている。収容部５４の形状は、他の継手部材の突出部の形状と略同一であるが僅かに収容部５４の方が、挿入方向に深く、端面５４ａの幅が突出部４０の端面４３の幅より狭くなっている。収容部２４は他の継手部材の突出部を完全に収容する。   The receiving portion 50 is completely embedded in the workpiece 100 such that the position in the one joining direction of the end face in the joining direction coincides with the joining surface 101. The receiving portion 50 includes two side walls 51 and a top portion 52, and the end surface on the right side of FIG. 7A is an opening 53, and the projection of another joint member can be inserted from the opening 53. It has become. The space inside the end face 54 a facing the two side surfaces 51, the ceiling 52 and the opening 53 is a housing 54 that accommodates the projections of other coupling members inserted from the opening 53. The shape of the housing portion 54 is substantially the same as the shape of the projecting portion of the other joint member, but the housing portion 54 is slightly deeper in the insertion direction, and the width of the end surface 54 a is greater than the width of the end surface 43 of the projection 40 It is getting narrower. The housing 24 completely accommodates the projections of the other coupling members.

突出部４０の形状を二軸楔形状とすることにより、突出部４０の端面を接続部６０の端面に確実に当接させて三次元的な位置決めを可能とする。そのため、継手部材２によれば、継手部材１による効果に加えて、挿入方向の荷重に対してもある程度抵抗できるという効果が得られる。   By making the shape of the projecting portion 40 into a biaxial wedge shape, the end face of the projecting portion 40 is reliably brought into contact with the end face of the connecting portion 60 to enable three-dimensional positioning. Therefore, according to the joint member 2, in addition to the effect of the joint member 1, an effect of being able to resist the load in the insertion direction to some extent is obtained.

接続部６０は、被接合部材１００に完全に埋設されている。接続部６０の挿入方向の一方の端面３１には受部２０が、接合方向の一方の端面３２には突出部１０が接続されている。突出部４０の端面４４と収容部５４の挿入方向の位置は、接続部６０の端面６１と一致する位置関係になっている。接続部５０の端面６１付近にはテーパー部６３を設けて、端面６４側の奥行き方向寸法を端面６１側の奥行き方向寸法より減少させている。これは、第１実施形態と同様に、接続部６０は、突出部４０と受部５０を上記のような位置関係で接続し、また、接合時に他の継手部材の突出部により押圧される際の荷重に耐えることができればよいため、材料無駄の無い形状としつつ、鍛造による加工をし易い形状にしたものである。従って、接続部６０の形状を図７に示したものと異なる形状とすることもできる。   The connection portion 60 is completely embedded in the bonded member 100. The receiving portion 20 is connected to one end surface 31 of the connecting portion 60 in the insertion direction, and the projecting portion 10 is connected to one end surface 32 of the connecting direction. The position in the insertion direction of the end surface 44 of the projecting portion 40 and the housing portion 54 is in a positional relationship that matches the end surface 61 of the connection portion 60. A tapered portion 63 is provided in the vicinity of the end face 61 of the connection portion 50 so that the dimension in the depth direction on the end face 64 side is smaller than the dimension in the depth direction on the end face 61 side. This is similar to the first embodiment, when the connecting portion 60 connects the projecting portion 40 and the receiving portion 50 in the positional relationship as described above, and when it is pressed by the projecting portion of another joint member at the time of joining. As long as it can withstand the load of the above, it is a shape that is easy to process by forging while having a shape free from material waste. Therefore, the shape of the connection portion 60 can be made different from that shown in FIG.

継手部材２の材料は、第１実施形態の継手部材１と同様に、所望の強度、製造コスト、被接続部材１００が使用される環境条件等に応じて種々のものを使用することができ、金属の他、合成樹脂、木、紙、ガラス、セラミックス、ゴム、或いはこれらの複合材料など適宜の材料を用いて適宜の製造方法で形成することが可能である。   Similar to the joint member 1 of the first embodiment, various materials can be used for the joint member 2 according to desired strength, manufacturing cost, environmental conditions under which the connected member 100 is used, etc. It can be formed by an appropriate manufacturing method using an appropriate material such as a synthetic resin, wood, paper, glass, ceramics, rubber, or a composite material of these, in addition to metal.

また、第１実施形態の場合と同様に、継手部材２と他の継手部材の形状及び材質は、製造コストの観点からは同一であることが好ましいが、異なる形状及び材質とすることもできる。また、収容部５４と他の継手部材の突出部の形状は同一でなくてもよい。なお、継手部材６による被接続部材の接合は、図４、５、６に示した第１実施形態における方法と同様に行うことができる。   Further, as in the case of the first embodiment, the shapes and materials of the joint member 2 and other joint members are preferably the same from the viewpoint of manufacturing cost, but may be different shapes and materials. Moreover, the shape of the accommodating part 54 and the protrusion part of another coupling member may not be the same. In addition, joining of the to-be-connected member by the coupling member 6 can be performed similarly to the method in 1st Embodiment shown to FIG.

次に、図８を参照して、本発明の第３実施形態である継手部材３について説明する。継手部材３は、被接続部材１００がコンクリート製部材等の流動体を固化させて製造される部材である場合の、本発明の適用例である。この継手部材３は、第１実施形態の継手部材１（その変形例も含む）または、第２実施形態の継手部材２（その変形例も含む）と同一形状の本体３ａを備えている。本体３ａの受部の接続面と対向する端面３ｂと、接続部の接続面と対向する端面３ｃには、それぞれ、アンカー７０が固定されている。アンカー７０として、例えば、直線状、或いはＵ字形、Ｌ字形等の適宜の形状の異形鉄筋等を用いることができ、想定される接合方向の荷重に対して、本体３ａが被接続部材から接合方向に抜けないようにアンカー７０の長さと径を設定する。アンカー７０の固定としては、溶接の他、ねじ部を設けて螺合しても良い。なお、コンクリート以外の材料の場合でも、継手部材と材料との付着だけでは接合方向の引き抜き抵抗が不十分な場合には、アンカーを設けると良い。   Next, with reference to FIG. 8, a joint member 3 according to a third embodiment of the present invention will be described. The joint member 3 is an application example of the present invention in the case where the connected member 100 is a member manufactured by solidifying a fluid such as a member made of concrete. The joint member 3 includes a main body 3a having the same shape as the joint member 1 of the first embodiment (including its modification) or the joint member 2 of the second embodiment (including its modification). An anchor 70 is fixed to the end face 3b opposite to the connection surface of the receiving part of the main body 3a and the end face 3c opposite to the connection surface of the connection part. As the anchor 70, it is possible to use, for example, a straight or a U-shaped, an L-shaped or other appropriate shaped rebar, and the main body 3a is joined from the connected member to the load in the assumed joining direction. The length and diameter of the anchor 70 are set so as not to slip out. As fixation of the anchor 70, a screw part may be provided and screwed together other than welding. Even in the case of materials other than concrete, it is preferable to provide an anchor if the adhesion between the joint member and the material alone is insufficient for the drawing resistance in the joining direction.

次に、図９を参照して、本発明の第４実施形態である継手部材４について説明する。継手部材４は、被接続部材１００がコンクリート製部材等の流動体を固化させて製造される部材である場合の、本発明の他の適用例である。この継手部材４は図８の継手部材３と同様の本体４ａとアンカー７０を備えている。継手部材４は更に、挿入方向から見た形状が略Ｕ字形若しくは馬蹄形の形態を成し、本体４ａの外周に接合面と略直角方向に配置された二枚の外周補強部材７１を備えている。外周補強部材７１は、馬蹄形を成す構造の本体４ａの外面に対して法線方向に凸設され、本体４ａと一体的に形成しても良く、別体として溶接や接着、嵌合によって設けても良い。外周補強部７１の凸設高さや幅や形状は、特に限定されるものではなく、要求水準に合わせて本体４ａを十分に補強出来るものであればよい。図９では、外周補強部材７１の挿入方向の位置は、アンカー７０と一致しているが、必ずしも一致しなくても良く、枚数も一枚又は三枚以上としても良い。また、アンカー７０を設けない場合にも外周補強部材７１を設けても良い。外周部補強部材７１を設けることによって、収容部が開くように変形することを防止し、継手の接合方向の引張強度を向上させることができる。この他、この外周補強部材７１によれば、継手部材４に対して作用し得る嵌合時における挿嵌方向に対する外力に対しても抵抗力を発揮し得る。   Next, a joint member 4 according to a fourth embodiment of the present invention will be described with reference to FIG. The joint member 4 is another application example of the present invention in the case where the connected member 100 is a member manufactured by solidifying a fluid such as a member made of concrete. The joint member 4 includes a main body 4 a and an anchor 70 similar to the joint member 3 of FIG. 8. The joint member 4 further includes two outer peripheral reinforcing members 71 having a substantially U-shaped or horseshoe-like shape when viewed in the insertion direction and disposed in a direction substantially perpendicular to the joint surface on the outer periphery of the main body 4a. .

In FIG. 9, the position in the insertion direction of the outer periphery reinforcing member 71 matches the anchor 70, but may not necessarily match, and the number may be one or three or more. The outer circumferential reinforcing member 71 may be provided also when the anchor 70 is not provided. By providing the outer peripheral portion reinforcing member 71, it is possible to prevent the housing portion from being deformed so as to open and to improve the tensile strength in the joint direction of the joint. In addition to this, according to this outer periphery reinforcing member 71, it is possible to exert a resistance against external force in the insertion direction at the time of fitting which can act on the joint member 4.

次に、図１０を参照して、本発明の第５実施形態である継手部材５について説明する。
継手部材５は、被接続部材１００がコンクリート製部材等の流動体を固化させて製造される部材である場合の、本発明の他の適用例である。この継手部材５は図９の継手部材４と同様の本体５ａとアンカー７０と外周補強部材７１を備えている。継手部材５は更に、本体５ａの接合面側の端面に配置され、接合面と平行な板状の接合面補強部材７２を備えている。接合面補強部材７２を接合面付近に配置することによって、接合面の剛性を高めることができる。 Next, with reference to FIG. 10, a joint member 5 according to a fifth embodiment of the present invention will be described.
The joint member 5 is another application example of the present invention in the case where the connected member 100 is a member manufactured by solidifying a fluid such as a member made of concrete. The joint member 5 includes a main body 5a similar to the joint member 4 of FIG. 9, an anchor 70, and an outer peripheral reinforcing member 71. The joint member 5 further includes a plate-like joint surface reinforcing member 72 which is disposed on the end surface of the main body 5 a on the joint surface side and is parallel to the joint surface. By arranging the joint surface reinforcing member 72 near the joint surface, the rigidity of the joint surface can be enhanced.

図１１に、本発明の継手部材１〜５を地中にトンネルを構築するシールド工法に適用した例を示す。シールド工法においては、工場等で予め製作したセグメント８１、８２を周方向に接合してリング８３を製作し、このリング８３を軸方向に順次接続してトンネル８０を構築する。セグメント８２は、最後に接合されるセグメントで、接合面がトンネルの軸方向に対して僅かに傾斜している。図１１では短い直線で記号的に示したセグメントの周方向の継手８４、８５に本発明を好適に用いることができる。   FIG. 11 shows an example in which the joint members 1 to 5 of the present invention are applied to a shield construction method for constructing a tunnel in the ground. In the shield method, segments 81 and 82 manufactured in advance in a factory or the like are joined in the circumferential direction to produce a ring 83, and the rings 83 are sequentially connected in the axial direction to construct a tunnel 80. The segment 82 is a segment to be joined last, and the junction surface is slightly inclined with respect to the axial direction of the tunnel. The invention can be advantageously used for the circumferential joints 84, 85 of the segments which are symbolically indicated by short straight lines in FIG.

図１２に、本発明の継手部材１、２を木製の本棚に適用した例を示す。本棚９０は、鉛直方向に配置される二枚の側板９１の間に、一枚の天板９２と複数の棚板９３を配置した構造となっている。図１２では短い直線で記号的に示した側板９１と天板９２の継手９４及び側板９１と棚板９３の継手９５に本発明を好適に用いることができる。木材等の部材に継手部材１、２を固定する方法としては、例えば、受部と連結部を収容できる空間を形成し、その空間に継手部材１、２を圧入し或いは接着剤等で固定する。継手部材１、２を圧入する場合は、受部及び挿入部に鬼目ナットを形成しても良い。継手部材１、２によれば、一体に形成されている突出部と接続部が、側板９１と天板９２及び側板９１と棚板９３にまたがって配置されている。そのため、継手部材１、２により構成される継手は、図１２の上下方向の剪断力に対して著しく高い強度を有している。二枚の側板９１の間に天板９２及び棚板９３を挿入する方向は、紙面に垂直な方向とすることも、紙面の上下方向とすることもできるが、上下方向とした方が、使用時に天板９２及び棚板９３が抜け出すことがなく好ましい。   FIG. 12 shows an example in which the joint members 1 and 2 of the present invention are applied to a wooden bookcase. The bookshelf 90 has a structure in which a top plate 92 and a plurality of shelf plates 93 are disposed between two side plates 91 disposed in the vertical direction. The present invention can be suitably used for the joint 94 of the side plate 91 and the top plate 92, and the joint 95 of the side plate 91 and the shelf plate 93, which are symbolically indicated by short straight lines in FIG. As a method of fixing the joint members 1 and 2 to a member such as wood, for example, a space capable of accommodating the receiving portion and the connection portion is formed, and the joint members 1 and 2 are press-fitted into the space or fixed with an adhesive or the like. . In the case where the joint members 1 and 2 are press-fitted, a fitting nut may be formed on the receiving portion and the inserting portion. According to the joint members 1 and 2, the integrally formed projecting portion and the connecting portion are disposed across the side plate 91, the top plate 92, the side plate 91, and the shelf plate 93. Therefore, the joint constituted by the joint members 1 and 2 has extremely high strength against the vertical shear force in FIG. The direction in which the top plate 92 and the shelf plate 93 are inserted between the two side plates 91 may be the direction perpendicular to the paper surface or the vertical direction of the paper surface, but the vertical direction is the direction of use. Sometimes the top plate 92 and the shelf plate 93 do not come off, which is preferable.

次に、本発明の第６実施形態である継手部材６について説明する。継手部材６は、被接合部材が型枠に流動性材料（例えばコンクリート、合成樹脂）を注入し硬化させて作成される場合に好適な実施形態である。図１３は継手部材６の斜視図、図１４は型枠１２０に配置した継手部材６の平面図である。図１３、１４では被接合部材１００の接合面１０１が上面となるように型枠を作成した場合を想定している。   Next, a joint member 6 according to a sixth embodiment of the present invention will be described. The joint member 6 is a preferred embodiment in the case where the member to be joined is produced by injecting and curing a flowable material (for example, concrete, synthetic resin) in a mold. FIG. 13 is a perspective view of the joint member 6, and FIG. 14 is a plan view of the joint member 6 disposed on the mold 120. In FIGS. 13 and 14, it is assumed that the mold is formed such that the bonding surface 101 of the workpiece 100 is the upper surface.

被接合部材１００の継手部材６は、図３に示した継手部材１の変形例と同様の本体６ａとアンカー７０を備えている。継手部材６ａは、突出部６ｂと連結部６ｄの境界が接合面と一致するように型枠に固定されるが、収容部６ｅが開放された形態の場合には、このままでは、収容部６ｅとなるべき空間に流動性材料が流入してしまい、収容部６ｅを形成することができない。そのため、継手部材６は、流入防止部材１１０を備えている。流入防止部材１１０は、収容部６ｅと接合時に必要な空間１０２の外周に沿った側壁１１１と、側壁１１１の下端に接続された底板１１２を備えている。側壁部１１１の上端には、必須ではないが、ループ状の把持部１１３が設けられている。側壁部１１１の上端は、接合面（打設面）から少し突出するようにしている。   The joint member 6 of the joined member 100 includes a main body 6 a and an anchor 70 similar to the modification of the joint member 1 shown in FIG. 3. The joint member 6a is fixed to the mold so that the boundary between the projecting portion 6b and the connecting portion 6d coincides with the joint surface, but in the case where the housing portion 6e is open, the housing portion 6e and The flowable material flows into the space to be done, and the housing portion 6e can not be formed. Therefore, the joint member 6 is provided with the inflow prevention member 110. The inflow prevention member 110 includes a side wall 111 along the outer periphery of the space 102 necessary for joining to the housing portion 6 e and a bottom plate 112 connected to the lower end of the side wall 111. At the upper end of the side wall portion 111, although not essential, a loop-like grip portion 113 is provided. The upper end of the side wall portion 111 is slightly protruded from the joining surface (casting surface).

図１３、１４に示すように、収容部６ｅの内面に側壁部１１１と底面１１２が当接するように、流入防止部材１１０を設置し、流動性材料を型枠１２０に注入する。流動性材料は流入防止部材１１０に阻まれて空間１０２及び収容部６ｅに流入することができない。
流動性材料が硬化した後、把持部１１３を図１３の上方に引き上げ流入防止部材１１０を除去すると空間１０２と収容部が形成される。この除去がスムーズに行えるように、側壁１１１と底板１１２は流動性材料と付着しにくい材料で形成するのが好ましい。 As shown in FIGS. 13 and 14, the inflow prevention member 110 is installed so that the side wall 111 and the bottom surface 112 abut on the inner surface of the housing 6 e, and the flowable material is injected into the mold 120. The flowable material is blocked by the inflow preventing member 110 and can not flow into the space 102 and the storage portion 6e.
After the flowable material hardens, the grip portion 113 is pulled upward in FIG. 13 to remove the inflow prevention member 110, thereby forming the space 102 and the housing portion. It is preferable that the side wall 111 and the bottom plate 112 be formed of a fluid material and a material that does not easily adhere so that this removal can be performed smoothly.

把持部１１３は、流動性材料の硬化後に流入防止部材１１０を除去しやすい形状であれば、図示のものと形状が異なっていても良く、取付位置も図示のものと異なっていても良い。また、把持部１１３を省略することもできる。   The grip portion 113 may have a shape different from that shown in the drawings as long as it is a shape that facilitates removal of the inflow prevention member 110 after curing of the flowable material, and the attachment position may also differ from that shown. Moreover, the holding part 113 can also be abbreviate | omitted.

流入防止部材１１０は、図１３、１４に示すような上部が開口した箱状の部材とするほか、収容部６ｅ及び空間１０２の形状に対応したブロック状の部材とすることもできる。
その場合、材料は例えば発泡スチロールを用いることができる。この場合も、把持部を設けても良い。 The inflow preventing member 110 may be a box-like member having an open upper portion as shown in FIGS. 13 and 14, or may be a block-like member corresponding to the shapes of the housing portion 6e and the space 102.
In that case, for example, expanded polystyrene can be used as the material. Also in this case, a grip portion may be provided.

Moreover, there is no limitation in the material and shape of the to-be-joined member to which the coupling member of each embodiment is applied, and any joining member may be applied as long as the joining surfaces are brought into contact with each other. . As a material, it is applicable to concrete, metal, a synthetic resin, a wood etc., for example. As a shape of a to-be-connected member, it is applicable to joining of members of the same kind, such as plate shape, columnar shape, and a block shape, or a different kind of member, for example. In addition to the shield segment and the bookcase illustrated above, concrete members (precast concrete members) by precast in general, general furniture, general construction materials for civil engineering and / or construction and construction including housing frame materials, various machines, etc. It can be applied to any item of

次に、第１実施形態乃至第６実施形態の継手部材の種々の変形例について説明する。これらの変形例は矛盾のない限り、相互に組み合わせて実施することができる。継手部材の基本的な構造は、第１実施形態の継手部材１と同様であるので、継手部材１と同様の構成要素には図１と同一の符号を付して説明を省略する。   Next, various modifications of the joint member according to the first to sixth embodiments will be described. These modifications can be implemented in combination with each other as long as there is no contradiction. Since the basic structure of the joint member is the same as that of the joint member 1 of the first embodiment, the same components as those of the joint member 1 are denoted by the same reference numerals as those in FIG.

図１５（Ａ）は、接合方向の引張強度を向上させた変形例を説明する図である。継手部材１ａは、収容部２４の端面１３１が接合面に対して天部２２側が連結部３０方向に入るように傾斜している。突出部１０の端面１３２も端面１３１と平行な方向に傾斜している。そのため、受部２０の側壁２１（図１参照）と他の継手部材の突出部の側面が係合するのに加え、端面１３１と端面１３２も係合し、継手の接合方向の引張強度（引抜強度や押込強度）が向上する。   FIG. 15A is a view for explaining a modified example in which the tensile strength in the bonding direction is improved. The joint member 1a is inclined such that the end surface 131 of the housing portion 24 is in the direction of the connecting portion 30 with respect to the joining surface. The end face 132 of the protrusion 10 is also inclined in the direction parallel to the end face 131. Therefore, in addition to engagement of the side wall 21 (see FIG. 1) of the receiving portion 20 and the side surface of the projecting portion of the other joint member, the end face 131 and the end face 132 are also engaged, and the tensile strength in the joint direction (extraction Strength and indentation strength) improve.

図１５（Ｂ）は、接合方向の引張強度を向上させた別の変形例を説明する図である。継手部材１ｂの収容部２４の端面１４３には、直方体状の凹部１４１が設けられている。また、突出部１０の端面１４４には、凹部１４４と略同形状の突部１４２が設けられている。そのため、受部２０の側壁２１（図１参照）と他の継手部材の突出部の側面が係合するのに加え、凹部１４１と他の継手部材の凸部１４２が係合し、継手の接合方向の引張強度（引抜強度）が向上する。なお、凹部１４１と凸部１４２が係合できれば、位置と形状は図１５（Ｂ）に示したものと異なっていても良い。   FIG. 15B is a view for explaining another modified example in which the tensile strength in the bonding direction is improved. A rectangular parallelepiped recess 141 is provided on the end surface 143 of the housing portion 24 of the joint member 1 b. Further, on the end surface 144 of the protrusion 10, a protrusion 142 having substantially the same shape as the recess 144 is provided. Therefore, in addition to engagement of the side wall 21 (see FIG. 1) of the receiving portion 20 with the side surface of the projection of the other joint member, the recess 141 engages with the projection 142 of the other joint member to join the joint The tensile strength in the direction (pull-out strength) is improved. In addition, as long as the recessed part 141 and the convex part 142 can be engaged, a position and a shape may differ from what was shown to FIG. 15 (B).

図１５（Ｃ）は、挿入方向の引張強度を向上させた変形例を説明する図である。継手部材１ｃの収容部２４の天部２２には、段差部１５２を有する三角形形状の凹部１５１が設けられている。突出部１０の他の継手部材の天部２２と当接する端面には凹部１５１と同形状（必須ではない。）で段差部１５４を有する凸部１５３が凹部１５１と略同数設けられている。そのため、段差部１５２と段差部１５４が係合し、継手の挿入方向の引張強度（引抜強度）が向上する。なお、凸部１５３や凹部１５１の数量や大きさ、形状等は、各種の要請に応じて適宜設定可能である。   FIG. 15C is a view for explaining a modified example in which the tensile strength in the insertion direction is improved. The top portion 22 of the housing portion 24 of the joint member 1 c is provided with a triangular recess 151 having a step portion 152. The same number (not essential) of the recessed portions 151 as the recessed portions 151 is provided with approximately the same number of convex portions 153 having the step portions 154 as the recessed portions 151 at the end face of the projecting portion 10 which contacts the top portion 22 of the other joint member. Therefore, the step portion 152 and the step portion 154 are engaged, and the tensile strength (extraction strength) in the insertion direction of the joint is improved. The number, size, shape and the like of the convex portion 153 and the concave portion 151 can be appropriately set according to various requests.

図１５（Ｄ）は、接合方向の引張強度を向上させた別の変形例を説明する図である。継手部材１ｄの収容部２４の天部２２には、波状の凹凸１６１が設けられている。突出部１０の他の継手部材の天部２２と当接する端面には、凹凸１６１と対称（必須ではない。）な形状の凹凸１６２が設けられている。そのため、凹凸１６１と凹凸１６２が係合し、継手の挿入方向の引張強度（引抜強度及び押込強度）が向上する。なお、凹凸１６１、１６２の数量や大きさ、形状等は、各種の要請に応じて適宜設定可能である。   FIG. 15D is a view for explaining another modified example in which the tensile strength in the bonding direction is improved. Wavy unevenness 161 is provided on the top portion 22 of the housing portion 24 of the joint member 1 d. On the end face of the projecting portion 10 in contact with the top portion 22 of the other joint member, an unevenness 162 symmetrical (not essential) to the unevenness 161 is provided. Therefore, the unevenness 161 and the unevenness 162 are engaged, and the tensile strength (pulling strength and pressing strength) in the insertion direction of the joint is improved. The number, size, shape, and the like of the asperities 161 and 162 can be appropriately set according to various requests.

図１６は、本発明の一実施形態に係る継手部材の一例を表す図であり、（Ａ）は斜視図、（Ｂ）は正面図、（Ｃ）は左側面図、（Ｄ）は底面図、（Ｅ）は右側面図である。本発明の一実施形態に係る継手部材２００は、例えば、図１６（Ａ）〜（Ｅ）に示すように、受部２２４の対向する側壁２２１ａ、２２１ｂの内面と、受部２２４に挿入された他の継手部材の突出部２１０の奥行き方向側の側面２１１ａ、２１１ｂとは、他の継手部材が接合方向及び／又は挿入方向に抜け出さないように係合する係合部２７１ａ、２７１ｂ、２７２ａ、２７２ｂを有する。尚、本発明の一実施形態に係る継手部材では、必ずしも対抗する面の両方に係合部を有する必要はなく、受部２２４内面の一の面に係合部が形成されていても良いし、対向しない複数の面に係合部が形成されていても良い。   FIG. 16 is a view showing an example of a joint member according to an embodiment of the present invention, wherein (A) is a perspective view, (B) is a front view, (C) is a left side view, and (D) is a bottom view , (E) is a right side view. The joint member 200 according to the embodiment of the present invention is, for example, as shown in FIGS. 16A to 16E, inserted into the inner surface of the opposing side walls 221a and 221b of the receiving portion 224 and the receiving portion 224. Engaging portions 271a, 271b, 272a, 272b engage with the side surfaces 211a, 211b on the depth direction side of the projecting portion 210 of the other coupling member so that the other coupling member is not pulled out in the joining direction and / or the insertion direction. Have. In the joint member according to the embodiment of the present invention, the engaging portions need not necessarily be provided on both of the opposing surfaces, and the engaging portions may be formed on one surface of the inner surface of the receiving portion 224. The engaging portion may be formed on a plurality of surfaces not opposed to each other.

係合部２７１ａ、２７１ｂ、２７２ａ、２７２ｂは、例えば、上記図１５（Ａ）〜（Ｄ）で説明したような、直方体状、三角形状、或いは円弧状（勿論、これらの形状に限定されることはなく、他の多角形状や不定形な形状でも良い）の凹部及び／又は凸部を有し、受部２２４側の係合部２７１ａ、２７１ｂと、他の継手部材の突出部２１０側の係合部２７２ａ、２７２ｂとが、他の継手部材の突出部２１０を受部２２４に挿入した時に係合されるように設計することができる。   The engaging portions 271a, 271b, 272a, 272b are, for example, rectangular, triangular or arc-shaped (as a matter of course, limited to these shapes as described in FIGS. 15A to 15D). And other concave and / or convex shapes may be used, and the engaging portions 271a and 271b on the receiving portion 224 side may be engaged with the projecting portion 210 on the other joint member. The mating portions 272a, 272b can be designed to be engaged when the projecting portion 210 of another coupling member is inserted into the receiving portion 224.

また、係合部２７１ａ、２７１ｂ、２７２ａ、２７２ｂは、図１６（Ｂ）、（Ｄ）に示すように、受部２２４に対する他の継手部材の突出部２１０の挿入方向が接合面２０１に対して傾斜するように形成されていても良い。このように、係合部２７１ａ、２７１ｂ、２７２ａ、２７２ｂを接合面２０１に対して傾斜させて形成することにより、継手の挿入方向及び接合方向の両方の引張強度（引抜強度）を向上させることができる。勿論、係合部が挿入方向に対して平行に形成される態様も除外されるわけではない。   Further, in the engaging portions 271a, 271b, 272a, 272b, as shown in FIGS. 16B and 16D, the insertion direction of the projecting portion 210 of the other joint member with respect to the receiving portion 224 is with respect to the joint surface 201. It may be formed to be inclined. Thus, by forming the engaging portions 271a, 271b, 272a, 272b at an angle with respect to the joint surface 201, it is possible to improve the tensile strength (extraction strength) in both the insertion direction and the joint direction of the joint. it can. Of course, the aspect in which the engaging portion is formed parallel to the insertion direction is not excluded.

また、係合部２７１ａ、２７１ｂ、２７２ａ、２７２ｂは、他の継手部材の挿入方向に向かって受部２２４の対向する側壁の内面の幅が漸次縮小するように形成しても良い。すなわち、受部２２４側の係合部２７１ａ、２７１ｂの（開口部側の幅ｗ１）＞（挿入方向奥側の端面の幅ｗ２）となるように、係合部２７１ａ、２７１ｂ、２７２ａ、２７２ｂを形成しても良い。例えば、係合部の縁部をテーパー状に形成しても良い。テーパー形状は、例えば、突出部２１０側の係合部２７２ａ、２７２ｂが、受部２２４への挿入方向の開口部側から奥側の端面へとかけて係合部間の幅が狭まるように形成し、受部側の係合部２７１ａ、２７１ｂは、突出部２１０側の係合部２７２ａ、２７２ｂと係合するように形成することができる。このようにすることで、一方の係合部の縁部を他方の係合部の縁部に確実に当接させて三次元的な位置決めを可能とし、挿入方向の荷重に対してもある程度抵抗できるという効果が得られる。勿論、例えば、上述の第２実施形態で説明したように、係合部以外の箇所も同様の構造となっていても良い。   In addition, the engaging portions 271a, 271b, 272a, 272b may be formed such that the width of the inner surface of the opposing side wall of the receiving portion 224 gradually decreases in the insertion direction of the other joint members. That is, the engaging portions 271a, 271b, 272a, 272b are set so that (the opening side width w1) of the engaging portions 271a and 271b on the receiving portion 224 side> (the width w2 of the end surface on the rear side in the insertion direction). You may form. For example, the edge of the engaging portion may be tapered. The tapered shape is formed, for example, such that the engaging portions 272a and 272b on the side of the projecting portion 210 narrow the width between the engaging portions from the opening in the insertion direction to the receiving portion 224 to the end surface on the back side. The engaging portions 271a and 271b on the receiving portion side can be formed to engage with the engaging portions 272a and 272b on the projecting portion 210 side. In this way, the edge of one engaging portion is reliably brought into contact with the edge of the other engaging portion to enable three-dimensional positioning, and the load in the insertion direction is also resisted to some extent. The effect of being able to Of course, for example, as described in the second embodiment described above, portions other than the engaging portion may have the same structure.

また、突出部２１０は、接合方向の少なくとも一部に、平行な側面２７３ａ、２７３ｂを有しその幅が最小となる首部２７４を有していても良い。平行な側面２７３ａ、２７３ｂを有する首部２７４を備えることにより、接合方向の荷重に対して受部２２４が外側に広がるのを防止することができる。また、この他にも、受け部２２４の隅等応力が集中し易い箇所については丸み面取りや傾斜面取り等を行っても良い。   In addition, the projecting portion 210 may have a neck portion 274 which has parallel side surfaces 273a and 273b and has a minimum width at least at a part of the joining direction. By providing the neck portion 274 having the parallel side surfaces 273a and 273b, the receiving portion 224 can be prevented from spreading outward with respect to the load in the joining direction. In addition to this, rounding, beveling, or the like may be performed on a portion where stress is likely to be concentrated, such as a corner of the receiving portion 224.

図１７は、本発明の一実施形態に係る継手部材の一例を表す図であり、（Ａ）は斜視図、（Ｂ）は正面図、（Ｃ）は左側面図、（Ｄ）は底面図、（Ｅ）は右側面図である。本発明の一実施形態に係る接手部品３００は、図１７（Ａ）〜（Ｅ）に示すように、係合部３７１、３７２が複数形成（ａ１，ａ２，・・・，ａｎ，ｂ１，ｂ２，・・・，ｂｎ）されている形態としても良い。係合部を複数形成することにより、受部３２４に他の接手部品の突出部３１０が挿入された際に、各々の係合部３７１、３７２（ａ１，ａ２，・・・，ａｎ，ｂ１，ｂ２，・・・，ｂｎ）が係合するため、継手の挿入方向及び接合方向の両方の引張荷重に対する応力を多段に分散することができ、嵌合部をよりコンパクトな大きさに設定することができる。複数の係合部は、図１７（Ａ）に示すように、連続して形成されていても良いし、間隔をあけて形成されていても良い。また、各係合部の形状は同一及び／又は相似形であっても良いし、一部が異なっていても良い。勿論、対応する係合部（例えば、受部３２４側の係合部３７１ａｉと対応する突出部３１０側の係合部３７２ａｉ（ｉ＝１，２，・・・，ｎ））は係合可能な形状とする。 FIG. 17 is a view showing an example of a joint member according to an embodiment of the present invention, wherein (A) is a perspective view, (B) is a front view, (C) is a left side view, and (D) is a bottom view , (E) is a right side view. As shown in FIGS. 17A to 17E, in the joint component 300 according to the embodiment of the present invention, a plurality of engaging portions 371 and 372 are formed (a 1 , a 2 ,..., An , b 1 , b 2 ,..., b n ) may be used. By forming a plurality of engaging portions, when the projecting portion 310 of the other catch part is inserted into the receiving portion 324, each of the engagement portions 371,372 (a 1, a 2, ···, a n , B 1 , b 2 ,..., B n ) can be engaged, so that stresses against tensile loads in both the insertion direction and the joint direction of the joint can be dispersed in multiple stages, and the fitting portion can be made more compact It can be set to the size. The plurality of engaging portions may be formed continuously as shown in FIG. 17A or may be formed at intervals. In addition, the shape of each engaging portion may be the same and / or similar shape, or may be partially different. Of course, the corresponding engagement portion (for example, the engagement portion 372a i (i = 1, 2,..., N) on the projection 310 side corresponding to the engagement portion 371a i on the reception portion 324 side) is engaged Make it possible shape.

図１７に示す本発明の一実施形態においても、図１６の例と同様に、各係合部は、受部３２４に対する他の継手部材の突出部３１０の挿入方向が接合面３０１に対して傾斜するように形成されていても良いし、各係合部は、他の継手部材の挿入方向に向かって受部３２４の対向する側壁３２１ａ、３２１ｂの内面の幅が漸次縮小するように形成しても良い。   Also in the embodiment of the present invention shown in FIG. 17, in the same manner as in the example of FIG. 16, in each engaging portion, the insertion direction of the protrusion 310 of the other joint member with respect to the receiving portion 324 is inclined with respect to the joint surface 301 Each engaging portion may be formed such that the width of the inner surface of the opposing side walls 321a and 321b of the receiving portion 324 gradually decreases in the insertion direction of the other joint member. Also good.

本発明の一実施形態に係る継手部材は、一体成形で製造しても良いが、複数の構成部材に分割して成形したものを接続及び／又は一体化して製造しても良い。例えば、継手部材を奥行方向の中心線に沿って二分割し、それぞれの部材を成形して接続可能な構成とすることで継手部材を製造しても良い。このようにすれば、例えば、上述した図１６や図１７に示すように受部の内面に係合部を有するような構造であっても比較的容易に成形することができる。或いは、突出部、接続部、受部の各々又は何れかで分割可能となっていても良い。勿論、分割する箇所や個数はこれらの例に限定されない。但し、継手部材として、挿入方向及び／又は接合方向の引張強度（引抜強度）に影響が出ないように分割することが望ましい。又、構成部材を接続する手段は特に限定されず、溶接、接着、締結の何れか、又はこれらの組み合わせによって行うことができる。締結に関しては、ネジ穴が貫通していても良いし貫通していなくても良い。   The joint member according to an embodiment of the present invention may be manufactured by integral molding, but may be manufactured by connecting and / or integrating parts which are divided and formed into a plurality of constituent members. For example, the joint member may be manufactured by dividing the joint member into two along the center line in the depth direction and forming the respective members so as to be connectable. In this way, for example, as shown in FIG. 16 and FIG. 17 described above, it can be relatively easily molded even with a structure having an engaging portion on the inner surface of the receiving portion. Alternatively, it may be divisible by each or any of the projecting portion, the connecting portion, and the receiving portion. Of course, the locations and the number of divisions are not limited to these examples. However, it is desirable to divide the joint member so as not to affect the tensile strength (pull-out strength) in the insertion direction and / or the bonding direction. Moreover, the means to connect a structural member is not specifically limited, It can carry out by welding, adhesion | attachment, fastening, or these combination. With regard to fastening, the screw holes may or may not penetrate.

図１８（Ａ）、（Ｂ）は接合方向の引張強度を向上させた別の変形例を説明する図である。図１８（Ａ）に示すように、継手部材１ｅの収容部２４の挿入方向の長さＬ１は、突出部１０の挿入方向の長さＬ２よりもやや長くなっている。図１８（Ｂ）は収容部２４に他の継手部材の突出部１０が挿入された状態であるが、収容部２４の端面１７１の幅ｂ５は突出部１０の端面１７２の幅ｂ６よりもやや小さくなっている。図１８（Ｂ）では見やすくするためにやや間隔をあけているが、実際には突出部１０の端面１７２の隅角部１７４が収容部の側面１７３に確実に当接し、側壁２１に食い込むようになっている。そのため、隅角部１７４と側壁２１の係合によって、継手の挿入方向の引張強度（引抜強度）が向上する。   FIGS. 18A and 18B are diagrams for explaining another modified example in which the tensile strength in the bonding direction is improved. As shown in FIG. 18A, the length L1 in the insertion direction of the accommodation portion 24 of the joint member 1e is slightly longer than the length L2 in the insertion direction of the projecting portion 10. FIG. 18B shows a state in which the protrusion 10 of another coupling member is inserted into the storage portion 24. However, the width b5 of the end surface 171 of the storage portion 24 is slightly smaller than the width b6 of the end surface 172 of the protrusion 10. It has become. In FIG. 18B, although a slight gap is provided to make it easy to see, in actuality, the corner portion 174 of the end surface 172 of the protrusion 10 reliably abuts on the side surface 173 of the housing portion and bites into the side wall 21. It has become. Therefore, the tensile strength (pull-out strength) in the insertion direction of the joint is improved by the engagement between the corner portion 174 and the side wall 21.

図１９（Ａ）、（Ｂ）は、抜け止め防止機構を備えた変形例を説明する図である。図１９（Ａ）に示すように、継手部材１ｇの収容部２４には、容器１８１が設けられ、容器１８１の内部には流体１８２が収容されている。また、突出部１０及び接続部２０には一端が収容部２４の端面１８４に開口し、他端が突出部１０の端面１８５に開口して収容部２４と空間１０２ｂを連通させる流路１８３も設けられている。   19 (A) and 19 (B) are diagrams for explaining a modification provided with a locking mechanism. As shown in FIG. 19A, the container 181 is provided in the housing portion 24 of the joint member 1g, and the fluid 182 is housed inside the container 181. Further, in the projecting portion 10 and the connecting portion 20, one end is opened to the end surface 184 of the accommodating portion 24, and the other end is opened to the end surface 185 of the projecting portion 10 to provide a flow path 183 communicating the accommodating portion 24 and the space 102b. It is done.

図１９（Ｂ）のように継手部材１ｆの収容部２４に他の継手部材１ｇの突出部１０が挿されると、容器１８１は破壊され流体１８２は突出部１０により押し出され流路１８３を通って空間１０２ａに流出する。ここで、流体１８２は、容器１８１から流出すると固化するものであり、空間１０２ａは固化した流体１８２により満たされる。そのため、突出部１０は固化した流体１８２により拘束され挿入方向に引き抜かれることがなくなる。なお、流路１８３は、一つ以上の孔や穴状及び／又は溝状のものであって、継手部材１ｆの挿嵌時において、流体１８２が初期に配置されていた空間、即ちここでは収容部２４から流体１８２が流路１８３を通じて空間１０２ａに移動するように構成されていればよく、収容部の位置や形状、流体１８２を収容する容器１８１の有無や形態、流路１８３の形態等は適宜設定可能である。例えば、突出部１０の挿入方向における前面と背面の両面に亘って連通するように流路を設けることで、継手部材の嵌合時に流体１８２が流路を通じて初期位置から嵌合後位置に移動するように構成することができる。   When the projection 10 of another joint member 1g is inserted into the housing portion 24 of the joint member 1f as shown in FIG. 19B, the container 181 is broken and the fluid 182 is pushed out by the projection 10 and passes through the flow path 183 It flows into the space 102a. Here, the fluid 182 solidifies when flowing out of the container 181, and the space 102 a is filled with the solidified fluid 182. Therefore, the protrusion 10 is not restrained by the solidified fluid 182 and is not pulled out in the insertion direction. The channel 183 is one or more holes, holes, and / or grooves, and a space in which the fluid 182 is initially disposed at the time of insertion of the joint member 1f, that is, the space here As long as the fluid 182 moves from the portion 24 to the space 102 a through the flow path 183, the position and shape of the storage portion, the presence or absence of the container 181 containing the fluid 182, the shape of the flow path 183, etc. It can be set as appropriate. For example, by providing a flow path so as to communicate both surfaces of the front and back in the insertion direction of the protrusion 10, the fluid 182 moves from the initial position to the post-fit position through the flow path when fitting the joint member It can be configured as follows.

流出したときに固化する流体としては、例えば、二液性の接着剤のように二種類の流体が混合されることにより固化するもの（この場合、容器１８１には図示しない仕切りを設け破壊されるまでは二液が混合しないようにする）や、大気に触れることにより固化する流体を挙げることができる。また、空間１０２ａの体積は収容部２４の体積よりも大きいことがあるので、流体１８２は固化するときに膨張したり、発泡したりすることにより体積が増大するものが好ましい。   As a fluid which solidifies when it flows out, it solidifies by mixing two kinds of fluids like a two-component adhesive, for example (in this case, a partition not shown in the container 181 is provided and broken) It is possible to mention the fluid that solidifies when exposed to the atmosphere or to prevent the two liquids from mixing. In addition, since the volume of the space 102 a may be larger than the volume of the housing portion 24, it is preferable that the fluid 182 expand and solidify when it solidifies and that the volume is increased.
