次に、本発明の実施形態に係る継手部品及び施工方法について、図を参照して説明する。
図１及び図２に示されるように、本実施形態に係る継手部品１は、内周面にネジ溝が形成された略筒状のスリーブ２、ボルト頭３１が扁平な多角形状のボルト３、及びスリーブ２が圧着した棒鋼４からなり、一端が接着系アンカーとなるアンカー側端部を構成し、他端が機械継手となる継手側端部を構成する。 Next, a joint component and a construction method according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIGS. 1 and 2, the joint component 1 according to the present embodiment includes a substantially cylindrical sleeve 2 having a thread groove formed on the inner peripheral surface, a polygonal bolt 3 with a flat bolt head 31, The sleeve 2 is made of a bar steel 4 that is crimped, and one end constitutes an anchor-side end portion that serves as an adhesive anchor, and the other end constitutes a joint-side end portion that serves as a mechanical joint.

スリーブ２は、両端が開口した略円筒形状からなる金属製の管である。このスリーブ２は、一端側が挿通部２１を構成し、他端側が螺合部２２を構成している。また、スリーブ２の中空部分は、棒鋼４やボルト３が挿し込まれる貫通孔２ａを構成しており、さらに、この貫通孔２ａのうち、挿通部２１の中空部分は挿通孔２１ａを、螺合部２２の中空部分は螺合孔２２ａを構成している。   The sleeve 2 is a metal tube having a substantially cylindrical shape with both ends opened. One end side of the sleeve 2 constitutes an insertion part 21, and the other end side constitutes a screwing part 22. Further, the hollow portion of the sleeve 2 constitutes a through hole 2a into which the steel bar 4 and the bolt 3 are inserted. Further, of the through hole 2a, the hollow portion of the insertion portion 21 is screwed into the insertion hole 21a. The hollow portion of the portion 22 constitutes a screwing hole 22a.

挿通部２１は、棒鋼４が挿入されると共に、内周面が棒鋼４に圧着される部分である。この挿通部２１に設けられている挿通孔２１ａは、開口部から棒鋼４の端部が挿入される孔であって、内周面は平滑で、棒鋼４の直径と略同じか、僅かに大きい径を有している。この挿通孔２１ａに棒鋼４が挿入され、この状態で外周面から径方向内側に押圧力を加える塑性加工が施されることによって、スリーブ２の内周面が棒鋼４に圧着している。   The insertion part 21 is a part into which the steel bar 4 is inserted and whose inner peripheral surface is crimped to the steel bar 4. The insertion hole 21 a provided in the insertion portion 21 is a hole into which the end of the steel bar 4 is inserted from the opening, and the inner peripheral surface is smooth and is substantially the same as or slightly larger than the diameter of the steel bar 4. It has a diameter. The steel bar 4 is inserted into the insertion hole 21a, and in this state, the inner peripheral surface of the sleeve 2 is pressure-bonded to the steel bar 4 by performing a plastic working that applies a pressing force radially inward from the outer peripheral surface.

螺合部２２は、ボルト３及び連結ボルト５（図４参照）が螺合する部分である。この螺合部２２に設けられている螺合孔２２ａは、棒鋼４よりも径が小さいボルト３及び連結ボルト５が螺合する孔であって、棒鋼４や挿通孔２１ａよりも径が小さく、内周面にはボルト３及び連結ボルト５に応じたネジ溝が形成されている。
また、この螺合部２２は、予め挿通部２１と同じ径で構成されていたものを、外周面から径方向内側に押圧されることによって縮径されている。 The screwing portion 22 is a portion where the bolt 3 and the connecting bolt 5 (see FIG. 4) are screwed together. The screwing hole 22a provided in the screwing portion 22 is a hole into which the bolt 3 and the connecting bolt 5 having a diameter smaller than that of the steel bar 4 are screwed, and has a diameter smaller than that of the steel bar 4 and the insertion hole 21a. A thread groove corresponding to the bolt 3 and the connecting bolt 5 is formed on the inner peripheral surface.
Further, the screwing portion 22 is reduced in diameter by being pressed in the radial direction from the outer peripheral surface, which has been configured in advance with the same diameter as the insertion portion 21.

ボルト３は、ボルト頭３１が扁平な多角形状からなり、ボルト軸３２が雄ネジを構成するボルトである。ボルト軸３２の外周面に形成されている雄ネジは、スリーブ２の螺合孔２２ａに形成されているネジ溝に対応したものであり、螺合孔２２ａに着脱可能に螺合させることができる。
なお、本実施形態におけるボルト３は、ボルト頭３１が扁平な六角形状からなるが、ボルト３を固定的に保持して継手部品１を回動させたり、ボルト頭３１を打突したりするのに好適であれば、他の多角形状等に構成することもできる。 The bolt 3 is a bolt in which the bolt head 31 has a flat polygonal shape, and the bolt shaft 32 forms a male screw. The male screw formed on the outer peripheral surface of the bolt shaft 32 corresponds to the screw groove formed in the screwing hole 22a of the sleeve 2, and can be detachably screwed into the screwing hole 22a. .
The bolt 3 in the present embodiment has a flat hexagonal bolt head 31, but the bolt 3 is fixedly held to rotate the joint component 1 or hit the bolt head 31. If it is suitable for, it can also comprise in other polygonal shapes.

このボルト３は、接着系アンカーを構成する棒鋼４側の端部が躯体に接着させる際に用いられ、その後、継手構造を形成する際にスリーブ２から取り外される。   The bolt 3 is used when the end portion on the steel bar 4 side constituting the adhesive anchor is bonded to the housing, and then removed from the sleeve 2 when forming a joint structure.

棒鋼４は、外周面に凹凸状の節が形成された異形棒鋼である。異形棒鋼であれば、スリーブ２の貫通孔２ａ内に挿入した棒鋼４をスリーブ２と圧着させた際、棒鋼４の外周面の節がスリーブ２の貫通孔２ａの内周面に食い込んで、より強固に棒鋼４とスリーブ２とを圧着させることができる。
なお、これに関わらず、本発明の実施において、棒鋼４は他の種類の棒鋼とすることもできる。 The steel bar 4 is a deformed steel bar in which uneven nodes are formed on the outer peripheral surface. In the case of a deformed steel bar, when the steel bar 4 inserted into the through hole 2a of the sleeve 2 is pressure-bonded to the sleeve 2, the nodes on the outer peripheral surface of the steel bar 4 bite into the inner peripheral surface of the through hole 2a of the sleeve 2, The steel bar 4 and the sleeve 2 can be firmly bonded to each other.
Regardless of this, in the practice of the present invention, the steel bar 4 may be another type of steel bar.

この棒鋼４の端部のうち、スリーブ２と反対側の端部は、接着系アンカーとなるアンカー側端部を構成し、躯体に設けられた穿孔内に挿入された接着剤封入カプセルを破砕するために、その先端が尖形状に形成されている。
なお、この先端の形状は、接着剤封入カプセルを破砕することができれば、各図において示す尖形形状とは異なる尖形形状であってもよい。 Of the ends of the steel bar 4, the end opposite to the sleeve 2 constitutes an anchor side end serving as an adhesive anchor, and crushes the adhesive-encapsulated capsule inserted in the perforation provided in the housing. Therefore, the tip is formed in a pointed shape.
The tip shape may be a pointed shape different from the pointed shape shown in each figure as long as the adhesive-encapsulated capsule can be crushed.

また、継手部品１を接着系アンカーとして用い、躯体に設けた穿孔内に棒鋼４を挿入させた際、穿孔内への棒鋼４の埋込み深さを識別するため、棒鋼４の外周面には一定の長さごとに目印４１が付されている。
この目印４１は、棒鋼４の外周面状において作業者が視認可能な態様で付されていればよく、塗料を塗布して目印４１としたものや、小さな凹部を形成して目印４１としたものなど、各種の態様によることができる。 In addition, when the joint part 1 is used as an adhesive anchor and the steel bar 4 is inserted into the perforation provided in the housing, the depth of the steel bar 4 embedded in the perforation is identified so that the outer peripheral surface of the steel bar 4 is constant. The mark 41 is attached | subjected for every length.
The mark 41 is only required to be attached to the outer peripheral surface of the steel bar 4 in such a manner that the operator can visually recognize it. The mark 41 is formed by applying a paint, or the mark 41 is formed by forming a small recess. It can depend on various aspects.

続いて、継手部品１を接着系アンカーとして用い、アンカー側端部を躯体に接着させる工程について、図３を参照して説明する。
まず、躯体１０の所定位置にドリル等で穿孔１０ａを穿設する。 Next, a process of bonding the anchor side end portion to the housing using the joint component 1 as an adhesive anchor will be described with reference to FIG.
First, a hole 10a is drilled at a predetermined position of the housing 10 with a drill or the like.

そして、穿孔１０ａ内に接着剤封入カプセル１１を挿入した状態で、継手部品１の棒鋼４を穿孔１０ａ内に挿入する。
棒鋼４の先端は尖形状に形成されており、これにより、穿孔１０ａ内の接着剤封入カプセル１１が割られ、接着剤封入カプセル１１に封入されていた接着剤が穿孔１０ａ内に漏出する。 Then, the steel bar 4 of the joint component 1 is inserted into the perforation 10a with the adhesive-encapsulated capsule 11 inserted into the perforation 10a.
The tip of the steel bar 4 is formed in a pointed shape, whereby the adhesive-encapsulated capsule 11 in the perforation 10a is broken, and the adhesive sealed in the adhesive-encapsulated capsule 11 leaks into the perforated 10a.

棒鋼４をそのまま、所定の有効埋込み深さまで穿孔１０ａ内に挿入する。
この際、スリーブ２に螺合しているボルト３を利用して、棒鋼４を容易に穿孔１０ａ内奥に挿入することができる。即ち、六角形状のボルト３を固定的に保持し、継手部品１を回しながら、棒鋼４を穿孔１０ａ内に回し入れることもできるし、ボルト３のボルト頭３１が扁平であることから、ボルト頭３１を打突して、棒鋼４を穿孔１０ａ内に挿し込んでいくこともできる。 The steel bar 4 is inserted as it is into the perforation 10a to a predetermined effective embedding depth.
At this time, the steel bar 4 can be easily inserted into the perforation 10a using the bolt 3 screwed into the sleeve 2. That is, while holding the hexagonal bolt 3 in a fixed manner and turning the joint part 1, the steel bar 4 can be turned into the bore 10 a, and the bolt head 31 of the bolt 3 is flat. The steel bar 4 can also be inserted into the perforation 10a by striking 31.

棒鋼４を所定の有効埋込み深さまで穿孔１０ａ内に挿入させた後は、硬化養生させる。
なお、穿孔１０ａ内への棒鋼４の埋込み深さは、穿孔１０ａ外に露出している目印４１を参照することにより把握することができる。 After the steel bar 4 is inserted into the perforation 10a to a predetermined effective embedding depth, it is hardened and cured.
In addition, the embedding depth of the steel bar 4 in the perforation 10a can be grasped by referring to the mark 41 exposed outside the perforation 10a.

棒鋼４が躯体に接着された後、継手側端部において、鉄筋と継手構造を形成する工程について、図４を参照して説明する。
まず、スリーブ２の螺合孔２２ａからボルト３を取り外す。
躯体に接着された棒鋼４と継手構造を形成する鉄筋７の端部には、スリーブ２と同じスリーブ６が圧着している。
ここで、スリーブ６は、スリーブ２と同様、一端側が挿通部６１を構成し、他端側が螺合部６２を構成している。そして、スリーブ６の中空部分は、鉄筋７や連結ボルト５が挿し込まれる貫通孔６ａを構成しており、さらに、この貫通孔６ａのうち、挿通部６１の中空部分は挿通孔６１ａを、螺合部６２の中空部分は螺合孔６２ａを構成している。 After the steel bar 4 is bonded to the housing, a process of forming a joint structure with a reinforcing bar at the joint side end will be described with reference to FIG.
First, the bolt 3 is removed from the screwing hole 22 a of the sleeve 2.
A sleeve 6, which is the same as the sleeve 2, is pressure-bonded to the end of a reinforcing bar 7 that forms a joint structure with the steel bar 4 bonded to the housing.
Here, like the sleeve 2, the sleeve 6 has an insertion portion 61 on one end side and a screwing portion 62 on the other end side. The hollow portion of the sleeve 6 constitutes a through hole 6a into which the reinforcing bar 7 and the connecting bolt 5 are inserted. Further, of the through hole 6a, the hollow portion of the insertion portion 61 is screwed into the insertion hole 61a. The hollow portion of the joining portion 62 constitutes a screwing hole 62a.

また、継手構造を形成する際に用いられる連結ボルト５は、外周面にネジ山が形成された円柱状の部材である。
この連結ボルト５の外径は、スリーブ２、６の螺合孔２２ａ、６２ａの径に対応しており、連結ボルト５は、内周面に雌ネジが形成された螺合孔２２ａ、６２ａに螺入させることができる。
さらに、連結ボルト５の軸心方向の長さは、螺合孔２２ａ、６２ａの長さの約２倍であり、一端側を一のスリーブ２の螺合孔２２ａに螺入させると共に、他端側をスリーブ６の螺合孔６２ａに螺入させることにより、棒鋼４と鉄筋７が挿入された一対のスリーブ２、６を連結することができる。 Moreover, the connection bolt 5 used when forming a joint structure is a columnar member in which a thread is formed on the outer peripheral surface.
The outer diameter of the connecting bolt 5 corresponds to the diameter of the screwing holes 22a and 62a of the sleeves 2 and 6, and the connecting bolt 5 is inserted into the screwing holes 22a and 62a in which a female screw is formed on the inner peripheral surface. Can be screwed in.
Furthermore, the axial length of the connecting bolt 5 is about twice the length of the screw holes 22a and 62a, and one end side is screwed into the screw hole 22a of the one sleeve 2 and the other end is screwed. By screwing the side into the screwing hole 62 a of the sleeve 6, the pair of sleeves 2 and 6 into which the steel bar 4 and the reinforcing bar 7 are inserted can be connected.

挿通孔２１ａ、６１ａの内周面が棒鋼４あるいは鉄筋７に圧着した二つのスリーブ２、６について、夫々の螺合孔２２ａ、６２ａの開口端部を向かい合わせにし、この螺合孔２２ａ、６２ａ内に、連結ボルト５の一端側あるいは他端側を螺合させる。
これにより、棒鋼４が圧着したスリーブ２と、鉄筋７が圧着したスリーブ６が連結ボルト５によって連結され、その結果、棒鋼４と鉄筋７が連結される。 With respect to the two sleeves 2 and 6 whose inner peripheral surfaces of the insertion holes 21a and 61a are pressure-bonded to the steel bar 4 or the reinforcing bar 7, the opening ends of the screwing holes 22a and 62a face each other, and the screwing holes 22a and 62a. Inside, one end side or the other end side of the connecting bolt 5 is screwed together.
Thereby, the sleeve 2 to which the steel bar 4 is crimped and the sleeve 6 to which the steel bar 7 is crimped are connected by the connecting bolt 5, and as a result, the steel bar 4 and the steel bar 7 are connected.

以上の本実施形態に係る継手部品１によれば、一端を接着系アンカーによって躯体に接着させつつ、他端に継手構造を形成させることができる。
また、一端を接着系アンカーとして躯体に接着させる際、スリーブ２に螺合させたボルト３によって、回動あるいは打突のいずれによっても棒鋼４を容易に躯体１０の穿孔１０ａ内に挿し込むことができる。
さらに、穿孔１０ａ内に挿し込まれた棒鋼４の埋込み深さを目印４１によって簡単に視認することができる。 According to the above-described joint component 1 according to the present embodiment, a joint structure can be formed at the other end while one end is adhered to the housing by the adhesive anchor.
Further, when the one end is bonded to the housing as an adhesive anchor, the steel bar 4 can be easily inserted into the perforation 10a of the housing 10 by either turning or striking with the bolt 3 screwed into the sleeve 2. it can.
Furthermore, the embedding depth of the steel bar 4 inserted into the perforation 10 a can be easily visually recognized by the mark 41.
