Have been. A door body 20 is attached to the inside of the outdoor side frame member 1 so as to be openable and closable. On the other hand, the indoor side frame member 5 is a frame member provided around the inner periphery of the door opening B on the indoor side on four sides.
Become attached to. This indoor side frame member 5 is not in contact with the outdoor side frame member 1 so that outdoor cool air does not transfer heat indoors. In addition, each member of the said outdoor side frame material 1 and the said indoor side frame material 5 is shape | molded by the extrusion type | mold material of aluminum. Further, an iron plate such as stainless steel may be partially attached to these members to improve the strength.

As shown in FIGS. 1 and 2, the heat insulating material 10 is sandwiched between the connecting piece 2 of the outdoor frame member 1 and the connecting piece 6 of the indoor frame member 5. , 6 are screwed with connection screws 11 to form heat-insulated connection portions 12. That is, a connection piece 2 is formed at one end of the outdoor frame material 1, and a connection piece 6 is formed on the indoor frame material 5 corresponding to the connection piece 2. The heat insulating material 10 is provided over substantially the entire circumference between the connecting piece 6 and the connecting piece 6. The connection pieces 2 and 6 and the heat insulating material 10 are provided with screw holes at a plurality of locations in the longitudinal direction corresponding to each other. The connection screw 11 connects the screw hole of the connection piece 2 and the heat insulation material 10 to each other. It penetrates into the screw hole of the connecting piece 6 and is screwed to form the heat insulating linking portion 12. The heat insulating material 10 is made of a hard member having a low thermal conductivity such as a hard rubber or a hard resin. The heat insulating material 10 is hollow and has an air layer formed therein. It is easy to deform in conformity with the contact surfaces with the pieces 2 and 6.

The indoor side frame member 5 is provided with an extending piece 7 which covers the inner peripheral side of the heat insulating connecting portion 12 and extends to the outdoor side, and a tip end of the extending piece 7 and the outdoor side frame member 1 are provided. The tight material opening 9 located on the outdoor side of the heat-insulating connecting portion 12 is formed therebetween. That is, the indoor side frame member 5 is formed with an extending piece 7 by extending the inner side piece to one side, and the extending piece 7 covers the inner circumferential side of the heat insulating connecting portion 12. And its tip is slightly bent toward the outer periphery. On the other hand, a protrusion 3 is formed on the inner peripheral surface of the outdoor side frame material 1, and the tight material opening 9 is formed as a space between the protrusion 3 and the extension piece 7. ing. The tight material opening 9 is connected to the heat insulating connecting portion 12.
It is located on the outdoor side. As described above, since the tight material opening 9 is arranged on the outdoor side of the heat-insulating connecting portion 12, the heat-insulating door frame and the heat-insulating door frame that does not require the tight material 8 form the door opening B. The dimensions can be made the same, so that the door body 20 can be shared and the door opening B can be unified. The projecting piece 3 does not need to be particularly provided to form the opening 9 for the tight material, and may be used as a screw hole of the outdoor side frame material 1 or another member. Therefore, the structure of the outdoor side frame member 1 can be simplified.

The tight material opening 9 is used as a working opening for the connection screw 11 of the heat-insulating connecting portion 12, and the tight material 8 is attached to the tight material opening 9. That is, the tight material opening 9 disposed almost in front of the heat-insulating connection portion 12 on the outdoor side is connected to the heat-insulating connection portion 12.
The connecting screw 11 has a diameter that allows it to be inserted, and is a working opening for screwing and mounting the connecting screw 11. A fitting leg 8a extending from the tight material 8 to the indoor side is fitted into the tight material opening 9 also serving as the work opening, and the tight material 8 is mounted. The tight member 8 is formed of a soft member having a low thermal conductivity such as a soft rubber or a soft resin.
It absorbs the impact when the door is closed and improves the heat insulation efficiency indoors and outdoors. Since the tight material 8 is attached to the tight material opening 9 which also serves as the work opening, the tight screw 8 prevents the connection screw 11 from being seen from the outdoor side. In tight material 8
A member for concealing the connecting screw 11 such as the protruding piece 8b provided in the above is unnecessary, and the member molding becomes easier.

Further, each of the connecting pieces 2, 6 and the heat insulating material 10
The abutment surface is made into a substantially U-shape and butted 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 bends and protrudes to one side, and the connection piece 2 and the heat insulating material 10 and the connection piece 6 and the heat insulating material Each of 10 is butted in an uneven shape. By forming the contact surfaces of the connecting pieces 2 and 6 and the heat insulating material 10 into a substantially rectangular shape and abutting them in an uneven manner, these members can be tightly and firmly connected via a wide range of surfaces. Can be.
When the connection screws 11 for connecting the connection pieces 2 and 6 are tightened when each member is attached, the connection 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

As described above, the present invention provides an insulated door frame formed by connecting an outdoor frame material and an indoor frame material via a heat insulating material, while providing an extended piece on the indoor frame material. Since the tight material opening located on the outdoor side of the heat-insulating joint is formed between the tip of the extension piece and the outdoor frame material, the dimensions of the heat-insulating door and door opening that do not require a tight material are the same. In addition to this, the door body can be used in common, and the production and management of members can be facilitated, and the door openings can be unified.

Further, according to the present invention, since the opening for the tight material is used as a working opening for the connecting screw of the heat insulating connecting portion, and a tight material is attached to the opening for the tight material, the tight material is hidden behind the tight material. Since the connecting screw becomes invisible from the outdoor side, there is no need to provide a member for hiding the connecting screw, and there is an effect that member molding can be simplified.
