The present invention relates to containers and devices, the aggregate-forming method using the same. Aggregate containers of the present invention is to form a skeletal body (10). The body 10 may aggregate space 12 formed therein as long as the left and right hexahedral shape are opened in the vertical direction. The laid the lower edge of the body 10 is supported with the guide rail 20 with the rail 22 such that the bottom plate 30 is supported to shield the lower portion of the aggregate space (12). Wherein the bottom plate (30) is provided with a hook (32). The hook 32 is to separate the bottom plate 30 in the body 10, is used. That the reinforcing bar (34) integral with the hanging loop (32) being fixed to the upper surface of the bottom plate 30, the body 10 has interference once skin 18 for avoiding interference with the reinforcing bars (34) it is formed. That the body 10 comprises a body reinforcing bar (17) across the top of the inlet is installed, the top laid inlet edge of the body 10 is provided with upper reinforcing bars 17. The upper inlet of the body 10 is provided with a pair of connection hooks obtain the longitudinal sides (16) to lift the body (10). According to the present invention it has the advantage that facilitates the formation of the aggregate and the treated part (3) of the aggregate for the formation of the aggregate part (3).
