Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal fitting for fixing a heat insulating wall base panel to a flange portion of a beam.

[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. 4, 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 between the metal studs b by a waterproof / moisture-proof sheet c. 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 constructed, it is easy to try to attach it to the steel beam because it is made of metal, but in the case of the heat insulation wall base panel proposed by the present inventors, the base material is wooden, An issue is to fix the steel beam with the steel 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 a heat insulating wall foundation panel to a flange portion under a steel frame beam.

[0008]

Means for Solving the Problems A beam fixing metal fitting for a heat insulating wall base panel of the present invention for solving the above-mentioned problems has a waterproof and moisture-proof sheet attached to one side of a wooden base material framed in a rectangular shape. A heat-insulating wall foundation panel provided with a heat-insulating material inside the frame, a metal fitting for fixing the upper end portion of the heat-insulating wall foundation panel and the beam in a state of standing upright under the beam,
A metal fitting body formed with two parallel cut portions, and a facing piece that is bent and formed into a U-shaped cross section that can be inserted into the cut portion of the metal fitting body.
A fixing member having an engaging portion adapted to be engaged with a flange portion below the beam, and fixing the metal fitting body to the upper end of the heat insulation wall base panel with a screw, and cutting the notch portion of the metal fitting body with the beam. The contact piece of the fixing member is inserted into the notch of the metal fitting body in the state of being brought into contact with the tip of the flange portion, and the facing piece of the fixing member is engaged with the flange portion of the beam. is there.

[0009]

According to the present invention, first, the metal fitting body is fixed to the upper end portion of the heat insulating wall base panel with a screw, and the heat insulating wall is provided under the beam so that the notch of the metal fitting body comes into contact with the tip of the flange portion of the beam. Set up the base panel. Then, in this state, the facing piece of the fixing member is inserted into the notch of the metal fitting body and meshes with the flange. Then, the metal fitting body is sandwiched and fixed between the fixing member and the flange portion, and the heat insulating wall base panel is fixed under the beam.

[0010]

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

FIG. 1 shows the outline of the entire structure of the beam fixing metal fitting 1, and FIGS. 2 and 3 show the fixed state of the beam fixing metal fitting 1.

That is, this beam fixing metal fitting 1 comprises a metal fitting body 2 and a fixing member 3, and is designed to fix the heat insulating wall base panel 4 and the beam 5.

The metal fitting body 2 is formed by bending a plate-like body, and a step portion 21 is formed in the central portion thereof.
The lower side of this step portion 21 is a panel fixing portion 22 for fixing to the heat insulating wall base panel 4, and the upper side thereof is the flange portion 51 of the beam 5.
And a flange contact portion 23 that abuts against. Among them, the panel fixing portion 22 is provided with a screw hole 24 for fixing the metal fitting body 2 to the heat insulating wall base panel 4 with the screw 6. On the other hand, the flange contact portion 23 is provided with two notches 25 that are parallel to each other along the longitudinal direction from the upper end side thereof. Further, the intermediate portion 26 sandwiched between the two notches 25 has a tip portion bent so as to position the fixed state by the fixing member 3.

The fixing member 3 is formed by bending into a U-shaped cross section so that it can be inserted into the notch 25 of the metal fitting body 2.
A mating portion 32 is provided on the facing piece 31 facing each other in this bent state. The meshing portion 32 is cut in a wave shape from the distal end portion of each facing piece 31 toward the proximal end portion,
It is shaped like a bite that is wide at some parts and narrow at some parts. Then, the flange portion 51 of the beam 5 is sandwiched and fixed by the meshing portion 32.

The heat-insulating wall base panel 4 is constructed by sticking a waterproof / moisture-proof sheet 43 on one surface in a state where the heat-insulating material 42 is packed in each section of the wooden base material 41 framed in a rectangular shape. By adopting the wooden base material 41, the heat insulating wall base panel 4 does not require a heat insulating process as in the case of using a metal stud. Further, since the heat insulating material 42 is packed into each section of the wooden base material 41 at the factory to form a panel, it is not necessary to form a gap between the wooden base material 41 and the heat insulating material 42 to reduce the heat insulating effect. Further, since the waterproof / moisture-proof sheet 43 is attached flush to one side of the heat insulating wall base panel 4, when the inner wall panel 40 is installed on this surface, the waterproof / moisture-proof sheet 43 is closely attached to the back surface of the inner wall panel 40. Can be made. That is, the heat insulating wall base panel 4 can solve various inconveniences when the conventional metal stud is used.

In order to construct the heat insulating wall base panel 4 thus constructed, first, the panel of the metal fitting body 2 is attached to the upper end of the surface of the heat insulating wall base panel 4 on which the waterproof / moisture-proof sheet 43 is attached. The fixing portion 22 is fixed with screws 6. Then, after laying a floor base material 73 composed of a heat insulating material 71 and a plywood 72 on the concrete floor material 7, the lower end portion of the heat insulating wall base panel 4 is inserted into a floor runner 74 fixed to the floor base material 73. The heat insulating wall foundation panel 4 is raised from the inner wall side to directly below the beam 5. Then, the flange contact portion 23 of the metal fitting body 2
Contact the flange portion 51 of the beam 5, so that in this state, the facing pieces 31 of the fixing member 3 are inserted into the notches 25 so that the engaging portions 32 are engaged with the flange portion 51 of the beam 5. (Not shown) or the like. As a result, the metal fitting body 2 fixed to the heat insulating wall base panel 4 is clamped and fixed between the flange portion 51 and the fixing member 3, and the heat insulating wall base panel 4 is fixed immediately below the beam 5. Becomes After the heat insulating wall base panel 4 is constructed in this manner, the inner wall panel 40 is attached to the surface of the waterproof / moisture proof sheet 43. Further, a field edge 92 is provided from the surface of the inner wall panel 40 via the field edge runner 91 at the position of the wooden base material 41 for receiving the field edge, and the ceiling panel 9 is constructed.

According to the fixing metal fitting 1, the heat insulating wall base panel 4 can be freely moved up and down by the notch 25 provided in the metal fitting body 2 before the fixing member 3 is driven in. It is possible to naturally adjust the insulative wall foundation panel 4 in a state where it is inserted and erected. Further, since the fixing member 3 is regulated by the intermediate portion 26 so as not to come into close contact with the metal fitting body 2 in the driven state, it can be easily loosened,
Even if the mounting position is wrong, it can be easily redone. Furthermore, since the heat insulating wall foundation panel 4 can be raised from the inner wall side and the metal fitting body 2 can be fixed by contacting the beam 5, the construction procedure is not particularly limited. However, the construction work can be performed easily without any trouble.

[0018]

As described above, according to the present invention, the metal fitting body fixed to the heat insulating wall base panel with the screw is brought into contact with the flange portion, and the fixing member is provided so as to sandwich the metal fitting body with the flange portion. Since this heat insulation wall base panel and the flange part under the beam can be fixed by extremely simple work such as striking, the advantages of installing the heat insulation wall base panel will be further enhanced, and on-site work will be efficient and easy. It can be carried out.
