BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a door frame mounting structure, and more particularly to a door frame mounting structure for an interior door for a partition wall of an apartment house or the like.

[0002]

2. Description of the Related Art A door frame is usually composed of left and right vertical frames mounted on studs standing on the left and right sides of an opening and an upper frame provided between the upper ends of the left and right vertical frames. By mounting the door body as the pivot point, the other vertical frame forms the door rest of the door body. Then, a plastic board and an interior wall are attached to both sides of the stud for finishing.

However, since the impact when the door is opened and closed is strongly applied to the upper end portion of the vertical frame, misalignment may occur at the joint between the plastic board and the interior wall at that portion. As the reinforcement of the opening frame, there is, for example, one in which a reinforcing member is provided around the opening frame to reinforce the frame itself, but this one takes into consideration the force that acts intensively on the upper end portion of the vertical frame. Rather, more load will be applied to the upper end portion of the vertical frame.

In addition, when mounting the door frame, it is necessary to assemble the stud and the vertical frame, but in this case, it is difficult to position the stud and the vertical frame, and the plastic board cannot be mounted smoothly. was there.

SUMMARY OF THE INVENTION The present invention was devised to solve such a problem, and aims to reinforce the cut at the upper end of the vertical frame which is the weakest point in the conventional door frame. It is the first purpose. A second object of the present invention is to facilitate positioning when assembling the vertical frame of the door frame and the stud.

[0006]

In order to solve the above-mentioned problems, the technical means adopted by the present invention is a plurality of mounting anchors at appropriate intervals in the length direction of the left and right vertical frames forming the door frame. Is a door frame mounting structure in which the vertical frame is mounted to studs standing upright on the left and right of the opening through the mounting anchors, and the mounting anchors face each other so as to hold the studs. And has a fin that extends
The mounting anchor is formed with a space for movably receiving the elongated reinforcing member in the vertical direction inside the vertical frame, and the reinforcing member is projected upward from the upper end of the vertical frame. It is characterized by being fixed to the stud.

In this way, the anchor is attached separately from the vertical frame.
In addition to adopting, and by using the space formed by the mounting anchor to install a long reinforcing material inside, by mounting the reinforcing material on the stud in a state of protruding above the upper end of the vertical frame,
The reinforcing material bears the force generated at the upper end of the vertical frame. When the door frame is installed, the reinforcing material is simply slid upward in the space and fixedly attached, so that the reinforcing material can be easily attached. The fastening of the reinforcing material is performed by, for example, a screw that penetrates the stud and the reinforcing material.

Further, in the present invention, the fitting anchor is provided with a fitting groove forming side located at the base end side of the fin, and the fitting groove forming side and the base end side of the fin are formed. The plate member is fitted in the groove portion having a substantially U shape in a plan view. The mounting anchor not only facilitates the positioning of the mounting with the stud by the opposed fins, but also facilitates the positioning when mounting the plate material such as the plastic board by the fitting groove.

The door body is rotatably mounted on the door frame by a hinge. However, if a mounting anchor is provided at a portion of the door frame where the hinge is provided, a part of the mounting anchor can be mounted on the hinge. Since it also functions as a back plate, it is not necessary to separately provide a back plate. The distance between the opposing fins has a dimension corresponding to the width of a predetermined stud, but since the mounting anchor is formed in the shape of a short side piece, if a groove is provided at the base of the fin, the fin can be formed. It can be folded with bare hands, and various studs can be handled by folding the fins on one or both sides.
