Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a heat insulation wall base panel,
The present invention relates to a metal fitting for fixing to a lip channel steel that constitutes a horizontal rail of a window frame.

[0002]

2. Description of the Related Art In general, in a building having a steel frame structure, when the outer wall has a curtain wall structure, it is necessary to construct a self-standing base material and a heat insulating material which adheres to the back surface of the inner wall when constructing the inner wall.

Therefore, conventionally, as shown in FIG. 5, self-standing metal studs b are installed by allocating them according to the width dimension of the heat insulating material a, and a bag is folded by a waterproof / moisture-proof sheet c between the metal studs b. After inserting the insulation a
The heat insulating material a was fixed using a push pin with an adhesive tape or an adhesive tape d.

[0004]

However, in the case of the above-mentioned conventional method of applying the base material, it is necessary to determine the total allocation from the beginning of the operation, which requires time. Further, when it takes time and effort to insert the heat insulating material a and the heat insulating material a is not inserted in a state suitable for the layout, a gap e is formed between the metal stud b and the heat insulating material a, and the heat insulating effect is improved. Will fall. Further, when constructing a partition portion orthogonal to the wall surface or a window portion of the wall surface, the bag-folded heat insulating material a is cut on site so that the dimensions match, and the cut end after cutting does not reduce the heat insulating effect. It is annoying to have to close it with tape. Furthermore, metal stud b
Since heat is transferred through the metal stud b
Hard rock wool f and the like must be fixed along the wall so that the heat insulating effect is not deteriorated. Further, since the metal stud b portion projects more than the heat insulating material a portion, when the inner wall panel g is installed on the surface thereof, the back surface of the inner wall panel g and the waterproof / moisture-proof sheet c on the surface of the heat insulating material a are formed. There will be a gap between them. As a result, dew condensation due to living humidity is likely to occur on the back surface of the inner wall panel g.

Therefore, the inventors of the present invention have proposed a heat insulating wall base panel in which a heat insulating material is provided in advance inside a frame of a wooden base material framed in a rectangular shape and a waterproof / moisture-proof sheet is attached on one side. The above-mentioned inconvenience was solved by constructing the panel.

However, when the heat insulating wall base panel is constructed, if the work is more time-consuming than when the conventional metal stud b is installed, the effect of the heat insulating wall base panel will be halved. . In particular, when the conventional metal stud b is applied, the metal stud b can be directly attached to the lip channel steel forming the window frame, but in the case of the heat insulation wall base panel proposed by the present inventors, Since the material is made of wood, it is a problem to fix it to the window frame efficiently and reliably.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a metal fitting for efficiently and reliably fixing the lip grooved steel forming the window frame and the heat insulating wall base panel. I am trying.

[0008]

In order to solve the above-mentioned problems, a metal fitting for fixing a window frame of a heat insulating wall base panel of the present invention has a waterproof and moisture-proof sheet attached to one side of a wooden base material framed in a rectangular shape. It is a metal fitting for fixing the heat insulating wall base panel, which has the heat insulating material inside the frame, to the horizontal rail of the window frame frame made of lip grooved steel and is abutted on the side surface of the lip grooved steel. A frame contact portion and a panel contact portion that is in contact with the side surface of the heat insulating wall base panel. A locking portion for locking the lip of the lip channel steel is formed, while a screw hole for fixing a screw is drilled in the panel contact portion.

[0009]

According to the present invention, first, the engaging portion is engaged with the lip portion of the lip channel steel, and the frame contact portion of the fixing metal fitting is brought into contact with the window frame. Then, the side surface of the heat insulating wall base panel to be constructed is positioned in a state of abutting against the panel abutting portion of the fixing metal fitting, and fixed by screw fixing.

[0010]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 shows an outline of the whole structure of the fixing metal fitting 1, and FIGS. 2 to 4 show a lip groove shape which constitutes a heat insulating wall base panel 2 and a horizontal rail of the window frame 3 by the fixing metal fitting 1. The fixed state with the steel 30 is shown.

That is, the fixing metal fitting 1 is composed of a plate-like member bent so as to form a frame abutting portion 11 and a panel abutting portion 12, and the heat insulating wall base panel 2 is formed from a lip grooved steel 30. The window frame 3 can be fixed to the cross rail.

The frame contact portion 11 and the panel contact portion 1
2 is formed by bending a plate-like body into an L shape. Of these, as shown in FIG.
A locking piece forming the locking portion 13 is fixed by a rivet 14 so that the locking portion 13 projects from the tip of the frame contact portion 11. The engaging portion 13 is adapted to engage with the lip portion 31 of the lip channel steel 30 with the frame contact portion 11 in contact with the side surface of the lip channel steel 30. In addition, this locked state is
Since it is maintained by the elasticity of the locking portion 13, it is preferable that the locking portion 13 be formed by bending a plate-shaped body having a thickness that allows an appropriate elastic force to be obtained. On the other hand, a screw hole 10 is provided in the panel abutting portion 12, and the panel abutting portion 12 can be fixed by a screw 4 in a state of abutting against the side surface of the heat insulating wall base panel 2.

The heat-insulating wall base panel 2 is constructed by sticking a waterproof / moisture-proof sheet 23 on one surface in a state where the heat-insulating material 22 is filled in each section of a wooden base material 21 framed in a rectangular shape. Further, a base plate 24 is provided at a position other than the wooden base material 21 in a section where screws are fixed later, and a waterproof / moisture-proof sheet 23 is attached to the surface of the base plate 24.
By adopting the wooden base material 21, the heat insulating wall base panel 2 does not require a heat insulating process as in the case of using a metal stud. In addition, since the heat insulating material 22 is packed in each section of the wooden base material 21 at the factory to form a panel, the wooden base material 21
It is also possible to prevent a gap between the heat insulating material 22 and the heat insulating material 22 from deteriorating the heat insulating effect. Furthermore, the waterproof / moisture-proof sheet 23
Is attached to one side of the heat insulation wall base panel 2 so that it is flush.
When the inner wall panel 5 is constructed on this surface, the waterproof / moisture-proof sheet 23 can be closely attached to the back surface of the inner wall panel 5. That is, the heat insulating wall base panel 2 can solve various inconveniences when the conventional metal stud is used.

The heat insulation wall base panel 2 thus constructed is used as a lip channel steel 3 which constitutes a horizontal rail of the window frame 3.
In order to fix it to 0, as shown in FIGS. 1 to 4, first, the lip portion 31 of the lip channel steel 30 to be constructed is to be constructed.
Then, the locking portion 13 of the fixing metal fitting 1 is locked, and the frame contact portion 11 is brought into contact with the side surface of the lip channel steel 30. Then, the side surface of the heat insulating wall base panel 2 is brought into contact with the panel abutting portion 12 of the fixing metal fitting 1, and is fixed with the screw 4.

When the heat insulating wall base panel 2 is installed on the upper side of the lip channel steel 30 which constitutes the upper horizontal rail of the window frame 3, as shown in FIG. It is fixed by the panel contact portion 12. Further, in this case, as shown in FIG. 4, the upper portion of the heat insulating wall foundation panel 2 is fixed to the beam 62 by the beam fixing metal fitting 61.

When the heat insulating wall base panel 2 is installed on the lower side of the lip channel steel 30 which constitutes the lower horizontal rail of the window frame 3, as shown in FIG. Are fixed by the panel contact portion 12. Further, in this case, as shown in FIG. 4, the lower portion of the heat insulating wall base panel 2 is fixed to the floor base material 74 including the heat insulating material 72 and the plywood 73 by the floor runner 71.

Further, after fixing, as shown in FIG. 4, the inner wall panel 5 is attached to the heat insulating wall base panel 2, and the window frame 81 is constructed so as to hide the panel contact portion 12. Further, a sash 82 is installed between the window frame 81 and the outer wall 8. Furthermore, the upper heat insulating wall base panel 2 of the lip channel steel 30 that constitutes the upper horizontal rail of the window frame 3 is
The field 92 is provided via the field runner 91, and the ceiling panel 9 is constructed.

As described above, the fixing metal fitting 1 locked to the lip grooved steel 30 and the heat insulating wall base panel 2 are fixed with screws 4 in a very simple manner without requiring fine positioning adjustment. It is possible to fix the heat insulation wall base panel 2 to the window frame 3 by various operations, and it is possible to perform on-site work efficiently and easily. Further, when the fixing metal fitting 1 is used, the heat insulation wall base panel 2 can be erected and connected from the inner wall side instead of being inserted and connected from the side, so that there is no room for insertion and movement. Even when the heat insulating wall base panel 2 is connected to the window frame 3 or the like, the connection work can be easily performed.

[0020]

As described above, according to the present invention, the locking portion of the fixing metal fitting is locked to the lip portion of the lip channel steel,
Since the heat insulating wall base panel can be fixed to the window frame by an extremely simple work such as fixing the panel contact part of this fixing bracket to the heat insulating wall base panel with a screw, the advantage of construction of the heat insulating wall base panel can be obtained. It will be even better, and work on site can be done efficiently and easily.
