2. Description of the Related Art A conventional wooden door comprises a middle plate surrounded by a door frame member having left and right vertical frames and upper and lower horizontal frames, and the vertical and horizontal frames of the door frame member are made of a wooden material. An inner holding frame and an outer holding frame disposed outside the inner holding frame, a surface material is bonded to both front and back surfaces between the inner holding frame and the outer holding frame, and a door central portion is provided on an inner surface of the inner holding frame. Are joined together.

However, the conventional door structure has a problem that warpage occurs due to a phenomenon in which the internal stress of the core material changes mainly due to a change in moisture.

[0004] Therefore, as a method of eliminating such a warp, 1) a method of inserting a spine into a middle plate to eliminate internal stress, 2) a method of coating a film to suppress fluctuation of moisture, and 3) a method of coating internal stress. A method using a homogeneous material (board, steel, etc.) as a small core material, 4) an H-shaped material having a large second moment of area as a highly rigid core material,
Alternatively, a method using a square steel material may be used.

However, in this type of door structure using a metal square pipe, an adhesive is used to join the metal square pipe and the wooden member.
Since the adhesive area is extremely small, and the adhesive used has good adhesive properties that are compatible only with wood, there is a problem that a twisting phenomenon occurs.

Also, as described above, since the adhesiveness to a metal square pipe is poor, the adhesive is changed to cope with the problem.
Since it is difficult to obtain uniform adhesiveness, there is also a problem in that the adhesive surface is suddenly partially peeled off, and "noise" is generated, which causes abnormal noise.

Further, if the metal square pipe is integrally joined to the wooden member by an adhesive,
When the door is no longer needed and is discarded, if it is required to separate the metal square pipe from the wooden member for recycling, the separation work becomes difficult, and separation is difficult for the user side. There is a problem that is troublesome.

Accordingly, it is an object of the present invention to provide a rigid wooden door structure which eliminates twisting and warping, as well as provides sufficient adhesive force between joints to eliminate a sound noise phenomenon. Is to do.
