８を載置するとともに可動支保エフの前端に設けられた
車輪１７によって可動支保エフを支承する。The movable support F, 8 is lifted up by the lifting devices 14 at both ends of the movable support F, and the movable support F, 8 is placed on the wheels 21 which are the third sliding bodies provided on the sandals 12 of the pier 10A. The movable support F is supported by wheels 17 provided at the front end of the movable support F.
これによって可動支保エフ、８は前後端がそれぞれ車輪
１７．２１によって前後方向走行自在に支承されたこと
になる。As a result, the front and rear ends of the movable supports F and 8 are supported by the wheels 17 and 21, respectively, so that they can move freely in the front and rear directions.
次に橋脚１０Ｂの固定支保工１１上設置されたサンドル
１２を撤去し、可動支保エフ、８を前進させる。Next, the sandals 12 installed on the fixed supports 11 of the pier 10B are removed, and the movable supports F, 8 are moved forward.
可動支保工８の前端部底面には前方に向って上り勾配の
滑動面２２が形成され、移動型枠装置１を前進していく

けられた車輪２１上に乗り上げて可動支保工８の前端が
サンドル１２上において支承される。A sliding surface 22 with an upward slope toward the front is formed on the bottom surface of the front end of the movable support 8, and as the movable formwork device 1 moves forward, the sliding surface 22 is first provided on the sandal 12 of the pier 10C. The front end of the movable support 8 is supported on the sandle 12 by riding on the wheels 21 .
可動支保工８前端の橋脚１０Ｃによる支承が開始される
前に可動支保エフの車輪１７による支承が解除されると
、可動支保エフが固定支保工１１上に直接摺接すること
になり、移動型枠装置１の前進が不可能になる。If the support by the wheels 17 of the movable support F is released before the support by the pier 10C at the front end of the movable support 8 is started, the movable support F comes into direct sliding contact with the fixed support 11, and the movable formwork Advancement of device 1 becomes impossible.
そこで可動支保工８は可動支保エフの前方に充分長く突
出し、車輪１７が固定支保工１１の前端に至ったときに
は既に滑動面２２が車輪２１に乗り上げるようになって
いる。Therefore, the movable support 8 protrudes sufficiently long in front of the movable support F, so that when the wheel 17 reaches the front end of the fixed support 11, the sliding surface 22 is already riding on the wheel 21.
移動型枠装置１をさらに前進させていくと可動支保エフ
前端の車輪１７は固定支保工１１から外れるが、このと

る。When the movable formwork device 1 is further advanced from this state, the rear end of the movable support 8 is connected to the wheels 2 on the sandals 12 of the pier 10A.
1, but before that, the wheels 17 provided at the rear end of the movable support F ride on the fixed support 11.
従って橋脚１０Ａのサンドル１２上における可動支保工
８の支承が解除される前に橋脚１０Ｂの固定支保工１１
上における車輪１７による支承が開始される。Therefore, before the support of the movable support 8 on the sand 12 of the pier 10A is released, the fixed support 11 of the pier 10B
The support by the wheels 17 on the top begins.
さらに移動型枠装置１を前進させると、可動支保工８が

乗り上げる。When the movable formwork device 1 is further advanced, the movable support 8 slides on the wheels 21 provided on the sandals 12 of the pier 10C, and the wheels 17 at the rear end of the movable support E slide on the fixed support 11. As it slides, the rear end of movable support F becomes pier 1.
When reaching the front end of the fixed support 11 of 0B, the wheels 17 at the front end of the movable support F ride on the sandals 12 of the pier 10C.
次に橋脚１０Ｂの固定支保工１１上にサンドル１２を設
