図１を参照すると、異形鉄筋からなる２つの鉄筋１２、１４（図３）を相互に接合するために用いられる機械式継手の１つである充填式継手が全体に符号１０で示されている。   Referring to FIG. 1, a filling joint, which is one of mechanical joints used for joining two reinforcing bars 12 and 14 (FIG. 3) made of deformed reinforcing bars to each other, is indicated generally by the numeral 10. .

充填式継手１０は、スリーブ又はカプラーと称される継手金物１６を有する。継手金物１６は同軸の２つの筒状空間１８、２０と、両筒状空間１８、２０をこれらの共通の軸線の伸長方向に相互に隔てる仕切壁２２とを有する。仕切壁２２は、好ましくは、前記共通の軸線の伸長方向におけるほぼ中央部に位置する。また、継手金物１６は各筒状空間１８、２０を規定する周壁面２４、２６を有し、各周壁面２４、２６は凹凸状を呈する。図示の各周壁面２４、２６は、その軸線方向に交互に配置されその周方向へ伸びる複数の突条及び複数の凹溝からなり、これらの突条及び凹溝により各筒状空間の周壁面２４、２６が凹凸状を呈している。   The filling type joint 10 has a fitting hardware 16 called a sleeve or a coupler. The joint hardware 16 includes two coaxial cylindrical spaces 18 and 20 and a partition wall 22 that separates the cylindrical spaces 18 and 20 from each other in the extending direction of the common axis. The partition wall 22 is preferably located substantially at the center in the extending direction of the common axis. Further, the joint hardware 16 has peripheral wall surfaces 24 and 26 that define the cylindrical spaces 18 and 20, and the peripheral wall surfaces 24 and 26 have an uneven shape. Each of the peripheral wall surfaces 24 and 26 shown in the drawing is composed of a plurality of ridges and a plurality of concave grooves alternately arranged in the axial direction and extending in the circumferential direction, and the peripheral wall surfaces of each cylindrical space are formed by these ridges and the concave grooves. 24 and 26 are uneven.

継手金物１６の両筒状空間１８、２０はそれぞれ２つの鉄筋１２，１４の端部１２ａ、１４ａを受け入れる。この受け入れのため、両鉄筋の端部１２ａ、１４ａが同時に又は時間的に前後して両筒状空間１８、２０内へこれらの仕切壁２２に向けてそれぞれ挿入される。   Both cylindrical spaces 18 and 20 of the joint hardware 16 receive the end portions 12a and 14a of the two reinforcing bars 12 and 14, respectively. For this reception, the end portions 12a and 14a of both reinforcing bars are inserted into the cylindrical spaces 18 and 20 toward the partition walls 22 respectively at the same time or before and after.

充填式継手１０は、さらに、その両筒状空間１８、２０にそれぞれ収容されたグラウトを有する。前記グラウトは継手金物１６とその各筒状空間１８、２０に受け入れられた各鉄筋１２，１４の端部１２ａ、１４ａとの間に存する隙間を満たす後記接着剤３２や、モルタル、セメントペースト等（図示せず）のような流体からなる。各筒状空間１８、２０内への前記グラウトの収容は、例えば、後述する容器２８、３０や袋（図示せず）に入れて、あるいは、各筒状空間１８，２０に前記グラウトを入れかつ該筒状空間に連なる継手金物１６の各開放端を蓋（図示せず）で塞ぐことにより、行うことができる。容器２８、３０、前記袋、前記蓋等は、継手金物１６の各筒状空間１８、２０に挿入される各鉄筋の端部１２ａ、１４ａの押圧力を受けて破壊可能であるガラス製、合成樹脂製等からなるものとすることができる。   The filling joint 10 further has grouts respectively accommodated in the cylindrical spaces 18 and 20 thereof. The grout is a postscript adhesive 32, mortar, cement paste, etc. that fills the gap between the joint hardware 16 and the ends 12a, 14a of the reinforcing bars 12, 14 received in the cylindrical spaces 18, 20 ( (Not shown). The grout is accommodated in each cylindrical space 18, 20, for example, in containers 28, 30 and bags (not shown), which will be described later, or in each cylindrical space 18, 20 This can be done by closing each open end of the joint hardware 16 connected to the cylindrical space with a lid (not shown). The containers 28, 30, the bag, the lid, etc. are made of glass and can be broken by receiving the pressing force of the end portions 12 a, 14 a of the reinforcing bars inserted into the cylindrical spaces 18, 20 of the joint hardware 16. It can be made of resin or the like.

継手金物１６の両筒状空間１８、２０にはそれぞれ接着剤入りの２つの容器２８，３０が配置されている。各容器２８、３０は、例えばガラス製のものからなり、継手金物１６の各筒状空間１８、２０への各鉄筋の端部１２ａ、１４ａの挿入時、各鉄筋の端部１２ａ、１４ａと筒状空間１８、２０の仕切壁２２との間において各鉄筋の端部１２ａ、１４ａの押圧力を受けて破壊される。   Two containers 28 and 30 each containing an adhesive are arranged in both cylindrical spaces 18 and 20 of the joint hardware 16. The containers 28 and 30 are made of, for example, glass, and when the end portions 12a and 14a of the reinforcing bars are inserted into the cylindrical spaces 18 and 20 of the joint hardware 16, the ends 12a and 14a of the reinforcing bars and the cylinders are inserted. Between the partition walls 22 of the cylindrical spaces 18 and 20, receiving the pressing force of the end portions 12 a and 14 a of the reinforcing bars, and being destroyed.

各容器２８、３０内に収容された接着剤３２は、継手金物１６と各鉄筋１２、１４とを接着可能である例えば二液性エポキシ樹脂のような合成樹脂からなる。前記二液性エポキシ樹脂は本剤（エポキシ樹脂）３２ａと硬化剤３２ｂとからなり、両剤は別梱されている。図示の例では、各容器２８、３０はその内部がガラス製の仕切り２８ａ、３０ａにより仕切られ本剤３２ａと硬化剤３２ｂとをそれぞれ収容する二室を有する。   The adhesive 32 accommodated in the containers 28 and 30 is made of a synthetic resin such as a two-component epoxy resin capable of bonding the joint hardware 16 and the reinforcing bars 12 and 14 to each other. The two-part epoxy resin is composed of a main agent (epoxy resin) 32a and a curing agent 32b, and both agents are packaged separately. In the example shown in the figure, the containers 28 and 30 each have two chambers that are partitioned by glass partitions 28a and 30a to store the main agent 32a and the curing agent 32b, respectively.

本剤３２ａと硬化剤３２ｂとをそれぞれ収容する前記二室は、図示の例におけるように継手金物１６の軸線方向（図上において左右方向）に関して互いに隣接するもの、継手金物１６の軸線に直交する方向(図上において上下方向)に関して互いに隣接するもの等とすることができる。   The two chambers containing the main agent 32a and the curing agent 32b are adjacent to each other with respect to the axial direction of the fitting hardware 16 (left and right in the drawing) as in the illustrated example, and are orthogonal to the axis of the fitting hardware 16. They can be adjacent to each other with respect to the direction (vertical direction in the figure).

本剤３２ａと硬化剤３２ｂとは各容器２８、３０及び仕切り２８ａ、３０ａが破壊されるとき、該容器内から各筒状空間１８、２０内に流出し、互いに混ざり合う。接着剤３２入りの両容器２８、３０は、継手金物１６の製造時、あるいは、その製造後これが使用に供されるまでの任意の時に、継手金物１６の両筒状空間１８，２０内に同時に又は時間的間隔をおいて挿入することにより配置することができる。なお、前記グラウトとして、前記モルタルやセメントペーストを用いるときは、継手金物１６の各筒状空間１８、２０内への各鉄筋の端部１２ａ、１４ａの挿入時期を考慮して、各筒状空間１８、２０内への前記モルタルやセメントペーストの収容時期を設定し、また、前記モルタルやセメントペーストの硬化時期の調整をしておく。   When the containers 28 and 30 and the partitions 28a and 30a are destroyed, the main agent 32a and the curing agent 32b flow out from the container into the cylindrical spaces 18 and 20 and are mixed with each other. The containers 28 and 30 containing the adhesive 32 are simultaneously placed in both the cylindrical spaces 18 and 20 of the joint hardware 16 at the time of manufacturing the joint hardware 16 or at any time after the manufacture until it is used. Or it can arrange | position by inserting at time intervals. When the mortar or cement paste is used as the grout, each cylindrical space is considered in consideration of the insertion time of the end portions 12a, 14a of the reinforcing bars into the cylindrical spaces 18, 20 of the joint hardware 16. The accommodation time of the said mortar and cement paste in 18 and 20 is set, and the hardening time of the said mortar and cement paste is adjusted.

本剤３２ａと硬化剤３２ｂとは、図示の例に代えて、４以上の偶数個の室に仕切られた容器の前記室に交互に収容することができる。さらに、これらの例に代えて、本剤３２ａと硬化剤３２ｂとをそれぞれ独立した２つのガラス製容器に、あるいは、例えば独立した１つのガラス製容器と該１つのガラス製容器に隣接する互いに独立した２つのガラス製容器とにそれぞれ収容することができる。   The present agent 32a and the curing agent 32b can be alternately accommodated in the chambers of the container partitioned into an even number of four or more chambers instead of the illustrated example. Further, in place of these examples, the present agent 32a and the curing agent 32b are separated into two independent glass containers or, for example, one independent glass container and the one adjacent to the one glass container. Can be accommodated in the two glass containers.

各接着剤３２は各容器２８、３０及びその仕切り２８ａ、３０ａの破壊に伴って各筒状空間１８、２０内に流出し、各筒状空間１８、２０を流動しこれを満たす（図２、図３参照）。したがって、各接着剤３２は、各筒状空間の周壁面２４，２６と各鉄筋の端部１２ａ、１４ａとの間の隙間を満たす液体であるグラウトとしての働きをなし、硬化後、継手金物１６と各鉄筋１２、１４とを相互に接着する。なお、ガラス製の各容器２８、３０及びその仕切り２８ａ、３０ａは、これらが破壊されるとき、多数の破砕片となり、流出した前記接着剤中に散らばり、あるいは、各鉄筋の端部１２ａ、１４ａと継手金物１６の仕切壁２２との間に押し潰された状態におかれる。   Each adhesive 32 flows out into each cylindrical space 18 and 20 with destruction of each container 28 and 30 and its partition 28a and 30a, and flows and fills each cylindrical space 18 and 20 (FIG. 2, (See FIG. 3). Accordingly, each adhesive 32 serves as a grout that is a liquid that fills the gaps between the peripheral wall surfaces 24 and 26 of each cylindrical space and the end portions 12a and 14a of each reinforcing bar. And the reinforcing bars 12 and 14 are bonded to each other. Each of the glass containers 28 and 30 and the partitions 28a and 30a are broken into a large number of pieces when they are broken, scattered in the adhesive that has flowed out, or the ends 12a and 14a of the reinforcing bars. And the partition wall 22 of the joint hardware 16 are crushed.

図２及び図３を参照して説明した充填式継手１０は、該充填式継手を介して両鉄筋１２、１４を相互に接合した後、両鉄筋１２、１４と共に、打設されるコンクリート（図示せず）中に埋設される。   The filling type joint 10 described with reference to FIG. 2 and FIG. 3 is concrete (see FIG. 2) that is placed together with the reinforcing bars 12 and 14 after the reinforcing bars 12 and 14 are joined to each other through the filling type joint. (Not shown).

充填式継手１０は、このような使用態様のほか、図４及び図５に示すような態様での使用が可能である。図４、図５に示す例にあっては、充填式継手１０の継手金物１６とその一方の筒状空間１８に挿入されかつ接着剤３２を介して継手金物１６に接着された一方の鉄筋１２とが、共に、打設コンクリート又はプレキャストコンクリートからなるコンクリートＡ中に埋設されている。この例にあっては、コンクリートＡに打ち継がれる他のコンクリート（図示せず）中に埋設される他方の鉄筋１４の端部１４ａが継手金物１６の他方の筒状空間２０に挿入可能であるように、継手金物１６の他方の筒状空間２０がコンクリートＡにおける打継面Ａ１に開放している。   The filling type joint 10 can be used in a manner as shown in FIGS. 4 and 5 in addition to such a usage manner. In the example shown in FIGS. 4 and 5, one of the reinforcing bars 12 inserted into the joint hardware 16 of the filling joint 10 and one of the cylindrical spaces 18 and bonded to the joint hardware 16 via the adhesive 32. Are embedded in concrete A made of cast concrete or precast concrete. In this example, the end 14a of the other reinforcing bar 14 embedded in another concrete (not shown) to be handed over to the concrete A can be inserted into the other cylindrical space 20 of the joint hardware 16. Thus, the other cylindrical space 20 of the joint hardware 16 is open to the joining surface A1 in the concrete A.
