The present invention relates to a beam body for construction. The beam body comprises: a long main body; two erection walls; one top wall connected to the top edge of the two erected walls; two bottom walls horizontally extended inward from the bottom edge of the two erection walls; and bottom erection walls extended upward from the free edge of the two bottom walls at a predetermined height. Multiple interval parts are installed between the two erection walls of the main body. The same interval parts maintain an interval of the two fixed erection walls. When erected on the beam bodies to be installed, the wooden pieces are matched with fixing parts of the beam bodies to install a foam board. One connection part is axially connected between the two beam bodies to extend a beam body. |
