By the way, since the said wooden heat insulation inner wall frame 14 is wooden, a level | step difference will arise in the said wooden frame 14b by the curvature of a tree, or the cross-sectional dimension error of the said wooden frame 14b, and it is bad for subsequent construction. It has problems such as impact and poor appearance.
[0006]
In order to solve these problems, the applicant of the present invention, as will be described in detail later in the section of `` Embodiment of the invention '', a metal frame formed to have a rectangular outer shape, A metal heat insulating inner wall frame having an inner heat insulating material provided inside surrounded by a frame body, and a back heat insulating material having substantially the same outer shape as the frame body and provided on a back side surface of the frame body. A new construction method that uses a heat insulating material inside the wall was developed. The metal heat insulating inner wall frame is formed so as to coincide with the arrangement interval of the window portion shaft assembly, and the metal heat insulating inner wall frame is simply fitted and fixed to the window portion shaft assembly. Since it can attach to the said window part shaft assembly, construction of the heat insulating material provided in the inside of a wall can be performed easily. Moreover, since the said frame is metal, the finishing precision after attachment improves.
[0007]
However, when a heat insulating material is provided in which the metal heat insulating inner wall frame as described above is provided at the upper and lower portions of the window, the wooden heat insulating inner wall frame 14 as in the conventional example is replaced with the window base 11 or window. If the mounting method of driving the lintel 12 with the nail 17 is adopted, a new problem described below occurs.
[0008]
The member which comprises the said metal heat insulation inner wall frame 4 is formed by bending a metal shape steel or a thin plate. As shown in FIG. 9, the upper and lower parts of the metal heat insulating inner wall frame 4 are members formed of thin plates, and an opening is formed on the side of the inner heat insulating material 2 in order to hold the inner heat insulating material 2. A U-shaped cross-section member 20 is provided so as to have However, if an attempt is made to drive the nail 17 against the U-shaped cross-section member 20 from the indoor side for mounting, the U-shaped cross-section member 20 is not very rigid in the direction in which the nail 17 is applied. Since the U-shaped cross-section member 20 is formed of a thin metal plate, it is difficult to drive the nail 17 into the U-shaped cross-section member 20 and may be deformed like the U-shaped cross-section member 20 shown in FIG. is there. Moreover, since the said metal heat insulation inner wall frame 4 has the said back surface heat insulating material 3 on the back side surface between the said window wooden stand 11 or the said window lintels 12, the position L of the determined appropriate thickness direction is provided. It was not easy to protect, and it was necessary to hit the nail 17 while visually confirming the position L, which was troublesome. Furthermore, it is also necessary to attach the metal heat insulating inner wall frame 4 to an appropriate position determined in the height direction. Therefore, when the nail 17 is driven and the metal heat insulating inner wall frame 4 is fixed, the metal heat insulating inner wall frame 4 is fixed. There is a problem in that the metal heat insulating inner wall frame 4 must be supported by hand from below and moved until it reaches the determined appropriate position, which places a burden on the operator. Therefore, a new mounting structure for mounting the metal heat insulating inner wall frame 4 to the window frame 6 has been required.
