にグラウトを充填することにより行っている。In this construction method, in order to protect the tensile steel material (3) from corrosion, the outer circumference of the tensile steel material (3) is covered with a fluid grout. The coating with this grout is
As shown in FIG. 7 and FIG. 8, a tensile steel material (3) is attached to the embedding sheath (4) penetrating the bridge girder (2) and the packing sheath (6) located in the packing gap (5) of the bridge girder (2). ) Is inserted.
Then, the embedded sheath (4) and the padding sheath (6)
It is done by filling the grout with.

のテープ（１０）を巻き付ける事が行われている。However, there is a possibility that fluid grout may flow out from the connecting portion between the packing sheath (6) and the embedded sheath (4).
In order to prevent this outflow, as shown in FIG. 7, after inserting the interlocking sheath (6) into the interlocking sheath (4) of the bridge girder (2), the interlocking sheath (6) and the interlocking sheath (4) are inserted. ) Is applied so that the mortar (8) is coated so as to cover the insertion interval (7). Further, as shown in FIG. 8, a sealing tape (10) is wound around.
また、実公昭６１−３９２８号公報記載の考案の如く、
埋込シースの内径に密着する輪ゴムを間詰シースの両端
に固定し、この輪ゴムを埋込シースに密着挿入する事に
より、隣接する橋桁間の間詰間隔を埋込シースで連結す
る方法が提案されている。Also, as in the invention described in Japanese Utility Model Publication No. 61-3928,
A method is proposed in which a rubber band that closely adheres to the inner diameter of the embedded sheath is fixed to both ends of the packing sheath, and this rubber band is closely inserted into the embedded sheath to connect the packing gap between adjacent bridge girders with the embedded sheath. Has been done.
発明が解決しようとする問題点 しかしながら、上記の方法はいずれも多くの手数を要
し、狭い高所の橋脚上での作業性を極めて悪いものとし
ている。特に、実公昭６１−３９２８号公報記載の考案
は、実施が不能か、極めて困難なものである。DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, each of the above methods requires a lot of troubles and makes workability on a pier at a narrow high place extremely poor. Particularly, the device described in Japanese Utility Model Publication No. 61-3928 is impossible or extremely difficult to carry out.
即ち、上記考案に於いて、間詰シースは両端の輪ゴム
を、隣接する２つの橋桁の埋込シース内に挿入するもの
であるから、２つの橋桁の間詰間隔よりも長い寸法のも
のでなければ成らない。そして、輪ゴムは埋込シース内
に密着挿入するものであるから、埋込シースに対しては
殆ど摺動することが出来ず固定的に挿入される。That is, in the above invention, the packing sheath is one in which the rubber bands at both ends are inserted into the embedding sheaths of two adjacent bridge girders. Therefore, the packing sheath must have a size longer than the packing gap between the two bridge girders. It doesn't happen. Since the rubber band is closely inserted into the embedded sheath, it cannot be slid on the embedded sheath and is fixedly inserted.
すると、一方の輪ゴムが、一方の橋桁の埋込シースに密
着固定された状態で、間詰シースは、２つの橋桁の間詰
間隔よりも大きな寸法分が、他方の橋桁方向に突出して
いる事になる。このような状態で、他方の輪ゴムを他方
の埋込シースに挿入するには、間詰シースが極めて軟弱
なもので容易に折曲したり、湾曲出来るものでなければ
成らない。Then, with one rubber band being in close contact with the embedded sheath of one bridge girder, the packing sheath should have a dimension larger than the spacing between the two bridge girders protruding toward the other bridge girder. become. In order to insert the other rubber band into the other embedded sheath in such a state, the filling sheath must be extremely soft and easily bendable or bendable.
しかし、間詰シースにはこのように軟弱なものではな
く、一定の剛性を有するものでなければ成らない。この
ように剛性を有する間詰シースを、２つの橋桁の間詰間
隔よりも長く形成して、これを２つの橋桁の埋込シース
に挿入するのは極めて困難か不可能なものである。However, the stuffing sheath must not have such weakness, but must have a certain rigidity. It is extremely difficult or impossible to form such a rigid padding sheath longer than the padding spacing of the two bridge girders and insert it into the embedded sheaths of the two bridge girders.
また、他の方法としては、一方の橋桁の埋込シースに、
一方の輪ゴムを挿入した後、他方の橋桁を移動しなが

な橋桁を動かしながら、他方の輪ゴムに埋込シースを合
致させ、しかも輪ゴムを、埋込シース内に橋桁を動かし
ながら密着挿入するのは多くの手数を要し、現実的には
行えないものである。Also, as another method, in the embedded sheath of one bridge girder,
A method of inserting one rubber band and then inserting the rubber sheath while aligning the embedded sheath with the other rubber band that is protruding is also considered. However, in this case as well, it takes a lot of trouble to move the bridge girder with a large weight, match the embedded sheath with the other rubber band, and insert the rubber band closely into the embedded sheath while moving the bridge girder. This is something that cannot be done.
