Constructional column used for installing prefabricated concrete wallboard

The utility model discloses a constructional column for mounting a precast concrete wallboard. The constructional column comprises a flat tube, an embedded part and a reinforcing column, wherein the flat tube is made of hollow square steel; the embedded parts are welded and fixed to the two ends of the flat tube and used for connecting floor slabs. The plate surface area of the embedded part is larger than the cross section area of the flat tube; the reinforcing columns are welded between the embedded parts at the two ends of the flat tube and welded to the side wall of the flat tube. The flat tube is arranged, the flat tube is connected with the floor through the embedded part, and the reinforcing column is welded on the side wall of the flat tube, so that the deformation of the constructional column during stress or non-uniform temperature change can be reduced, the wall body is prevented from cracking, the construction quality is improved, secondary treatment is not needed, and in the actual construction,
