DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for mounting a heat insulating inner wall frame for simplifying installation of a heat insulating material provided inside a wall of a building such as a house at a corner of the building. Regarding the structure.

[0002]

2. Description of the Related Art Conventionally, as a construction method for providing a heat insulating material inside a wall, a method of mounting a wooden heat insulating inner wall frame 51 to a frame 52 as shown in FIG. 10 is known.
The wooden heat-insulating inner wall frame 51 is composed of a wooden frame 55 formed by combining a vertical frame 53 and a horizontal frame 54 so as to have a rectangular outer shape, and a thermal insulation provided inside the wooden frame 55. It is composed of a material 56. The heat insulating material 56 is formed by housing a heat insulating material such as glass wool or rock wool in a bag body, and its outer shape is a substantially rectangular shape having substantially the same shape as the space inside the wooden frame 55. It is formed so that it becomes. Then, the attachment of the wooden heat-insulating inner wall frame 51 to the frame 52 is performed by driving the frame 55 into the frame 55 or the floor surface 57 of the heat-insulating inner wall frame 51 adjacent to the periphery by driving a nail 58 into place. Alternatively, it is performed by fixing to the frame 52 using a predetermined mounting bracket 59.

However, according to the conventional method of applying a heat insulating material, since the frame 55 of the heat insulating inner wall frame 51 is made of wood,
Since the frame 55 is warped or a step is formed on each surface of the frame 55 due to an error in the cross-sectional dimension of the frame 55, when the frame 55 is subsequently constructed, the frame 52 or the adjacent heat-insulating inner wall frame is formed. There is a problem that a slight gap is easily generated between the gap 51 and the center.

[0004] Therefore, as will be described in detail in the section of “Embodiments of the Invention”, the applicant of the present application has proposed a metal frame 1 formed to have a rectangular outer shape, A metal heat-insulating inner wall having an internal heat insulating material 2 provided in the inside surrounded by a circle, and a back heat insulating material 3 having substantially the same outer shape as the frame 1 and provided on a back side surface of the frame 1. A construction method of providing a heat insulating material inside the wall using the frame 4 was newly developed (see FIG. 5). The metal heat-insulating inner wall frame 4 is formed so as to match the interval of the shaft set 13, the metal heat-insulating inner wall frame 4 is fitted into the shaft set 13, and the frame 1 is connected to the shaft set 1.
Since the heat insulating material can be attached to the frame 13 only by fixing the heat insulating material to the frame 3, the heat insulating material provided inside the wall can be easily installed. In addition, since the frame 1 is made of metal and has high dimensional accuracy, almost no gap is formed between the frame 13 and the adjacent metal heat-insulating inner wall frame 4 even when the frame 1 is installed. Can be installed without causing.

[0005] However, the metal heat insulating inner wall frame 4 as described above.
In the case where the heat insulating material provided inside the wall is constructed by using the above, the structure is largely different from that of the conventional wooden heat insulating inner wall frame 51, for example, the back heat insulating material 3 is provided on the back side surface of the frame 1. Due to the difference, the same method as the conventional method of constructing the heat insulating material using the wooden heat insulating inner wall frame 51 cannot be used.
Therefore, a new mounting structure for mounting the metal heat-insulating inner wall frame 4 to the frame 13 is required.
