PROBLEM TO BE SOLVED: To provide a movable form for continuously and satisfactorily molding a porous concrete composition with a small quantity of binder to coarse aggregate. SOLUTION: The movable form for continuously molding concrete structures of the same cross-sectional shape has a molding part 2 provided with a lateral pair of side plates 2A facing each other, and a top plate 2B forming an upper face; a receiving frame part connected with the front end of the molding part; and a hopper part 5 connected with the upper end of the receiving frame part to receive ready mixed concrete supplied to the molding part 2, from the outside. The hopper part 5 is formed as a vibrating frame 8 vibrated by a vibrator 7, and the inside of the vibrating frame is divided into a plurality of regions 10 by a partition member 9. Each region 10 is formed into a passage of predetermined length for allowing ready mixed concrete to pass through. Consequently, even if the porous concrete composition is used for ready mixed concrete, vibration is propagated to the whole composition to attain satisfactory molding. COPYRIGHT: (C)2006,JPO&NCIPI
