Precast wall having increased pouring resistance

A precast wall having an integrated wall structure comprising concrete between precast panels, the precast wall comprising:

• an outer panel and an inner panel spaced apart at a distance and facing each other;
• a plurality of truss connection members connecting the outer panel and the inner panel;
• and
• rail members buried in the outer panel and the inner panel, respectively, and connected to the truss connection members,
• wherein the truss connection members include horizontal members spaced apart at a distance and horizontally connecting the rail members and inclined members respectively connecting the rail members in an oblique direction between one horizontal member and another horizontal member of the horizontal members;
• and
• coupling members respectively coupled to one surface of a corresponding rail member of the rail members connected to the truss connection members, in a longitudinal direction, wherein:
• the rail members comprise extension members extending in longitudinal directions and buried in the outer panel and the inner panel and a plurality of link members connected to the extension members;
• the coupling members comprise end portions being bent in a same direction and threads being formed on the end portions;
• the precast wall further includes a plurality of reinforcing members connecting the extension members;
• and
• the coupling members are coupled to one surface of the link members with the reinforcing members being fitted between the coupling members and the link members.
