Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to the structure of a door frame in a house, etc.
The present invention relates to a door frame structure that is easy to assemble and has good workability.

[Prior Art] In general, in determining the internal structure of a house, it is not enough to simply consider the habitability, and it is necessary to respond to the occupants' demand for comfort by also considering the sufficient designability. I won't. For example, various considerations have been made around the opening of the wall for attaching the door. 2 to 5 show an example of the structure of the door frame applied to the opening for mounting the door. The frame 2 is attached to the inner peripheral surface of the opening of the wall body 1, and By fixing the frame 3 to the recess 2a on the side surface of 2, the joint between the frame 2 and the wall 1 can be hidden by the frame 3, and the design of the opening of the wall 1 can be improved. it can.

[Problems to be solved by the invention] By the way, as a method of attaching the wall 1 and the frame 2, when nailing is performed from the inner peripheral surface side of the frame 2, the nail head is exposed to the inside of the room to improve the design. An adhesive is generally used because it damages. However, in order to attach the wall body 1 and the frame 2 with an adhesive, after applying an adhesive to the back surface of the frame 2 and bringing it into contact with the inner peripheral surface of the wall body 1, a predetermined device or the like is used. Since it was necessary to temporarily press the frame 2, it took time and effort to assemble the door frame. In order to avoid such an inconvenience, there is also a method of nailing from the inside of the recess 2a of the frame 2 to the wall body 1 side and then holding the nail head, as shown by the one-dot chain line in FIG. However, in this method, for example, when a nail is driven as shown by A in FIG. 5, it is difficult to drive the nail head completely into the frame 2 because the hammer does not enter the recess 2a. Workability is poor. Further, when driving in a nail as shown by B in FIG. 5, it is necessary to drive the nail diagonally from the opening end of the recess 2a toward the wall. There was a disadvantage that it was time consuming and it took time to accurately nail.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a door frame structure that is easy to assemble and has good workability.

[Means for Solving the Problems] Therefore, the present invention is directed to a wall body in which face materials are attached to the front and back surfaces of a frame body, and a rectangular opening for attaching a door is formed at a predetermined position, and the front and back surfaces. A base mounted on the inner peripheral surface of the opening in a state of being inserted between the members and having a recess at the opening end of the side surface along the longitudinal direction, and integrally fixed to the inner peripheral surface side of the base And a nailing surface provided by chamfering at the opening end on the wall side of the recess, a fitting portion whose one end fits in the recess, and the other end of the fitting portion. Frame extending substantially vertically outward from the part and covering the nailing surface and the inner peripheral side of the face material, and being attached along the longitudinal direction of the frame, and the inner periphery of the frame. The door body is provided so as to project toward the surface side, and the wall body and the frame drive a nail from the nailing surface to the wall body. It is characterized in that they are inserted into each other and attached to each other, and that the extending piece covers the nailing surface and the inner peripheral side of the face material.

[Embodiment] FIG. 1 is a view showing an embodiment of the structure of the door frame according to the present invention.

In this figure, 10 is a wall. This wall 10 is a frame
It is made up of wooden panels with 11 facings on each side. The wall 10 has an opening 13 for mounting the door 50. The opening 13 is formed in a substantially rectangular shape when the whole is viewed from the front.

A frame 20 is attached to the inner peripheral surface of the opening 13 (the upper part of the opening 13 is shown in the illustrated example). The frame 20 is composed of a base plate 21 attached to the opening 13 side and a decorative plate 22 integrally fixed to the inner peripheral surface side of the base plate 21. The base 21 is formed in a long shape having a substantially rectangular cross section, and the width thereof is formed to be substantially equal to the width of the frame body 11, and is inserted between the front and back face materials 12. It is attached to the frame body 11 in the closed state. The corners of the widthwise end surfaces on the inner peripheral side of the base 21 are
It is cut out in a rectangular shape when viewed in cross section. That is,
The frame 20 as a whole has a recess on the side surface along its longitudinal direction.
20a is provided. A nail striking surface 23 is provided by chamfering at the opening end of the recess 20a on the wall 10 side. The nail striking surface 23 is formed to be inclined at about 45 °. At the center of the nail striking surface 23 in the width direction,
A substantially V-shaped groove 24 is provided along the longitudinal direction of 23. Nails 25 are driven into the groove 24 at regular intervals. The nail 25 penetrates through the base 21 and the frame 11 and is driven in. That is, the wall body 10 and the frame
The reference numeral 20 indicates that the nails 25 are attached to each other by driving the nails 25 into the wall body 10 from the nail striking surface 23. Further, a recess 22a is formed in the center of the decorative plate 22 in the width direction along the longitudinal direction thereof. The recess 22a has 40
However, the convex portion 40a provided on one side thereof is fitted and attached by an adhesive.

The frame 20 has a long frame 30 along the longitudinal direction.
Is attached. The frame 30 is formed by arranging a fitting portion 31 attached to the frame 20 and an extending piece 32 extending so as to cover the lower end portion on the front surface side of the face material 12 in a cross-sectional angle shape. It is a thing.

Next, the assembling means of the structure of the door frame of the present embodiment configured as described above will be described.

First, the base 21 of the frame 20 is brought into contact with the inner peripheral surface side of the frame body 11 of the wall body 10. Then, the groove 2 formed in the nailing surface 23 of the recess 20a
