Do.
鋳型定盤を架設させてコンクリート流し込み作業及びコンクリート固めを行い、図５Ｎのように、固まったコンクリートにより梁主筋７１０及び梁あばら筋７２０を被覆させて梁７００を形成させ、固まったコンクリートは橋あばら筋８１０及び鉄筋籠２１０を被覆させる複合橋体８４０となり、橋台８００を形成させる。梁主筋７１０は主杭の連結杭部３００の柱面から突出させ橋台８００へ進入させる連結筋となり、橋台８００を更に突出させ他の主杭の連結杭部３００の柱面へ連結させて、梁の梁主筋７１０とする。 As shown in FIG. 5N, the main plate 710 and the beam stirrup 720 are covered with the solid concrete to form the beam 700, and the solid concrete is loosened from the bridge. A composite bridge body 840 that covers the reinforcing bar 810 and the reinforcing bar 210 is formed, and the abutment 800 is formed. The beam main reinforcement 710 becomes a connection reinforcement that protrudes from the column surface of the connection pile portion 300 of the main pile and enters the abutment 800, further protrudes the abutment 800 and is connected to the column surface of the connection pile portion 300 of the other main pile, It is assumed that the beam main reinforcement 710.
以上、本考案はこのような実施形態に限定されるものではなく、考案の趣旨を逸脱しない範囲において、種々の形態で実施することができる。 As mentioned above, this invention is not limited to such embodiment, In the range which does not deviate from the meaning of invention, it can implement with a various form.
