Partition and construction method thereof

A partition comprising:

• at least two stands (1) spaced apart from each other, wherein each of the stands (1) comprises a first panel (11), a second panel (12) corresponding to the first panel (11) and a lateral plate (13) connecting the first panel (11) and the second panel (12);
• at least one inner plate (3), wherein two sides of the inner plate (3) are respectively fixed to and between the two stands (1);
• and
• two outer plates (4, 5) respectively fixed to and between the first panel (11) of each stand (1) and the second panel (12) of each stand (1), wherein the two outer plates (4, 5) and the inner plate (3) form two spaces (6, 7) respectively,
• wherein the lateral plate (13) is bent to form a bending portion (14) on each stand (1), the bending portion (14) forms a groove (141), an extending plate (142) extends outwardly from a bottom of the groove (141) along a concave direction of the groove (141), one of the two sides of the inner plate (3) is plugged into the groove (141) of one of the stands (1) while the other side of the inner plate (3) is positioned on the extending plate (142) of the other stand (1), and
• wherein the bottom of the groove (141) is non-coplanar to the lateral plate (13) and an opening direction of the groove (141) faces toward the lateral plate (13).
