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.
