Door frame structure and method for mounting door frame structure

A door frame structure comprising:

• a first frame body having a first groove portion recessed along an outer periphery of a jamb, and a first coupling portion adjacent to the first groove portion;
• a first reinforcing member that is installed at a predetermined position in the first groove portion, and has a first projection formed thereon;
• a second frame body having a second groove portion recessed along an outer periphery of a jamb, and a second coupling portion that couples to the first coupling portion of the first frame body, wherein the first frame body and the second frame body substantially align with each other and the second coupling portion is disposed adjacent to the second groove portion;
• a second reinforcing member that is installed at a predetermined position in the second groove portion, and has a second projection formed thereon;
• a wall having a wall opening formed in which the first frame body and the second frame body are fitted;
• and
• a mounting angle including at least two surfaces one of which is fixed to the first reinforcing member and another of which is fixed to an inner periphery of the wall, wherein
• the mounting angle is a unitary piece,
• the first reinforcing member is installed slidably with respect to the first groove portion, and
• the second reinforcing member is fixed with respect to the second groove portion.

A method for mounting a door frame structure comprising the steps of:

• installing a first reinforcing member at a predetermined position in a first groove portion recessed along outer peripheries of at least three sides of a first frame body being a frame;
• fixing one surface of a mounting angle having at least two surfaces to the first reinforcing member and fixing another surface to an inner periphery of a wall in which a wall opening is formed;
• installing a second reinforcing member at a predetermined position in a second groove portion recessed along outer peripheries of at least three sides of a second frame body being a frame;
• and
• coupling a second coupling portion of the second frame body to a first coupling portion of the first frame body such that the first frame body and the second frame body face each other, wherein
• the mounting angle is a unitary piece,
• the wall having the wall opening formed in which the first frame body and the second frame body are fitted,
• the first coupling portion is disposed adjacent to the first groove portion and the second coupling portion is disposed adjacent to the second groove portion,
• a first projection is formed on the first reinforcing member, and
• a second projection is formed on the second reinforcing member.

• the wall having the wall opening formed in which the first frame body and the second frame body are fitted,
• the first coupling portion is disposed adjacent to the first groove portion and the second coupling portion is disposed adjacent to the second groove portion,
• a first projection is formed on the first reinforcing member, and
• a second projection is formed on the second reinforcing member.
