The present invention relates to a pi truss structure. In the pi truss structure, in which a bracing part is coupled to a coupling groove defined on the inside of an upper and lower portion of a pi, respectively, web members having two rows of the portions of the pi are disposed and coupled so as to face each other at a right angle within a plate-shaped flange member, and the coupling groove having a ??shape is defined inward in the lengthwise direction. Also, one side of each of the web members is disposed on the flange member, the other side being bent outward so as to form a reinforcing flange part. The coupling grooves of the upper and lower portions of the pi are disposed facing each other so as to couple coupling mechanisms to the coupling grooves, respectively. Also, the bracing part is coupled to the coupling mechanisms. |
