Combination Structure of Doorframe and Reinforcing Member of Doorframe

摘要

The door frame and stiffener joining structure according to the present invention includes a door installation part 11 formed on a side of an outer side of the door frame and having a long side in the longitudinal direction and a wooden insert part A pair of protrusions 14 protruding rearward so as to form a recessed portion 13 in a spaced apart space formed in the longitudinal direction on the inner side of the protrusion 14, The inclined surface 15a is formed on the inner side of the oblong surface and is elongated in the longitudinal direction and inclined at an acute angle from the inner lower portion to the outer upper portion along the protruding direction of the protruding portion 14. The inclined surface 15a is formed from the inclined surface 15a to the protruding portion 14, And a vertical surface (15b) perpendicularly formed to the upper surface of the door frame (15); A bottom portion 21 formed in a shape of a cross section in the shape of a letter "C" and elongated in the longitudinal direction of the door frame 10 and in contact with the bottom surface of the recessed portion 13; At least one of the side portions 22 and the side portions 22 which are bent at the opposite sides of the recessed portion 13 are horizontally bent outward and contact with the outer end surface of the projected portion 14, A plurality of protrusions 22 protruding outwardly and spaced a predetermined distance in the longitudinal direction of the door frame 10 and inserted into any one of the protrusion insertion grooves 15, Preventing protrusion (24) for preventing the protrusion (24) from being detached from the recessed part (13). And a control unit.
