It is provided. On the other hand, the indoor frame member 5 is integrally formed with a connecting piece 6 at an end on the outdoor side. The connecting piece 6 is provided along substantially the entire circumference of the indoor frame member 5 and The connection piece 2 of the outer frame member 1 is opposed to the connection piece 2.

The heat insulating material 10 sandwiched between the connecting piece 2 and the connecting piece 6 is a hollow member disposed substantially over the entire circumference between the connecting piece 2 and the connecting piece 6. Thus, the shape is substantially adapted to the space formed by the connecting pieces 2 and 6. The heat insulating material 10 is made of hard rubber
It is made of a hard member having a low thermal conductivity such as a hard resin. In the present embodiment, an air space is formed by making the inside hollow, and the thermal conductivity inside and outside is reduced, and it is easily deformed in accordance with the contact surface with each of the connecting pieces 2 and 6. I have.

The connecting pieces 2 and 6 and the heat insulating material 10 are provided with screw holes at a plurality of positions corresponding to each other in the longitudinal direction. The connecting screws 11 are connected to the screw holes of the connecting pieces 2. It penetrates through the heat insulating material 10 to reach the screw hole of the connecting piece 6 and is screwed. The connection piece 6 has a thread groove formed on the inner periphery of the screw hole when the connection screw 11 is screwed, and has a slightly thick central portion so that the screw groove can be formed. ing.

The contact surfaces between the connecting pieces 2 and 6 of the outdoor frame material 1 and the indoor frame material 5 and the heat insulating material 10 are formed into a substantially rectangular shape and are abutted in an uneven shape. That is, in the present embodiment, each of the connection pieces 2 and 6 and the heat insulating material 10 are formed in a substantially rectangular shape that is bent and projected to one side, and the connection piece 2 and the heat insulating material 10 and the connection are formed on the bent and projected surface. The piece 6 and the heat insulating material 10 are butted in an uneven shape. In this manner, the contact surfaces between the connection pieces 2 and 6 and the heat insulating material 10 are formed in a substantially rectangular shape and are abutted in an uneven shape, whereby these members are tightly and firmly connected via a wide range of surfaces. be able to. When the connecting screw 11 for connecting the connecting pieces 2 and 6 is tightened when each member is attached, the connecting pieces 2 and 6 may be tightened.
By applying a correcting force to the heat insulating material and the heat insulating material 10, the positional deviation between these members can be automatically corrected.

In the present embodiment, the contact surfaces of these members need not be shaped as shown in FIGS. 1 and 2, but may be shaped as shown in FIGS. That is, as shown in FIG. 4, the connecting piece 2 has a protruding shape on one side and the connecting piece 6 has a protruding shape on the other side, and the heat insulating material 10 has a shape substantially adapted to each of the connecting pieces 2, 6. May be formed. Alternatively, as shown in FIG. 5, each of the connecting pieces 2 and 6 may be formed to project in a direction opposite to that of FIG. These Figure 4

Further, as shown in FIG.
Is provided with a hook-shaped extending piece 7 so as to cover the inner peripheral side of the heat insulating material 10. The distal end of the hook-shaped extending piece 7 and the connecting piece 2 of the outdoor side frame material 1 are connected to each other. Tight material opening 13 between
The tight material 12 is fitted in the tight material opening 13. This tight material 12 is used for the door body 20.
And a fitting leg 12b extending from the main body portion 12a to the indoor side. The space between the door body 20 and the outdoor side frame member 1 is provided. The hermetic shape improves the heat insulation efficiency inside and outside, and more reliably prevents the dew condensation of indoor air.

As described above, in the present embodiment, the extending piece 7 is formed in a hook shape and the tight material 12 is disposed on the inner peripheral side of the connecting screw 11, but it is not necessarily required to be on the inner peripheral side. That is, as shown in FIG. 3, the indoor side frame member 5 is provided with an extending piece 7 that covers the inner peripheral side of the heat insulating material 10 and extends to the outdoor side. The tight material opening 13 may be formed between the outer frame material 1 and the tight material 12 may be fitted into the tight material opening 13. In this case, the door opening B may be used for both the heat-insulating door body requiring the tight material 12 and the non-insulating door body requiring no tight material 12.
Can be made the same, the door body 20 can be shared, and the opening operation of the door opening B can be unified.

In this embodiment, as shown in FIGS. 1 and 2, a projecting piece 12c is formed on the main body 12a of the tight material 12 so as to extend to the outer peripheral side.
2c serves as a cover for the connecting screw 11 so that the connecting screw 11 cannot be seen from the outdoor side. On the other hand, when the tight material 12 is arranged as shown in FIG. 3, the connection screw 11 can be hidden by the tight material 12 itself, and the tightly extending material 12 is formed on the outer peripheral side of the main body of the tight material 12. The projecting piece 12c that has been used becomes unnecessary.
In this case, the fastening operation of the connecting screw 11 is performed through the tight material opening 13.

[0015]

As described above, according to the present invention, the contact surface between each connecting piece and the heat insulating material is reduced in the heat insulating door in which the outdoor frame material and the indoor frame material are connected via the heat insulating material. Since it is shaped like a letter and butted in an uneven shape, tightening the connecting screw causes the connecting piece and the heat insulating material to contact in an inclined manner, generating a correcting force between these members, and automatically correcting the positional deviation between these members. Therefore, there is an effect that the work of attaching the frame material can be performed accurately and easily.

Further, according to the present invention, since the contact surfaces of the connecting pieces and the heat insulating material are formed in a substantially rectangular shape and butted in an uneven shape, the members can be fastened through a wider surface, and these members can be connected. There is an effect that the connection can be made tightly and firmly.
