The seal line A and the seal line B are formed as shown in FIG. In addition, as shown in FIG. 7, a water barrier 66 is attached to the combined portion of the outer sash and the inner sash to form a seal line C shown in FIG. Therefore, if the outdoor side and the indoor side can be insulated along the continuous seal line of the seal line A, the seal line C, and the seal line B shown in FIG. The conduction can be interrupted.

However, when the sash lower frame is to be formed from a shape material such as an extruded aluminum alloy, it is easier to assemble the structure by forming a heat insulating line in a straight line.
Therefore, as shown in FIG. 6, the insulation line shown in FIG. 1 is formed along the seal line B along the entire length of the lower frame so that the insulation line does not fall outside the watertight line.
When the heat insulating connecting member is disposed at the position of 3a (13b), the portion (a) shown in FIG. 6 is on the indoor side, but is in contact with the outdoor base member of the lower frame. In addition, the portion on the right side from the room to the outside of the room of the upper surface member for the inner sash,
Since it is located outdoors, it is transmitted to the left indoor side through the inner member of the inner sash. That is, if the heat conduction to the portion (a) in FIG. 6 is not interrupted and the outside air is lower than room temperature, there is a technical problem that dew condensation occurs in the portion (a). Was.

In view of the above technical background, an object of the present invention is to provide an outdoor lower frame flat sash having an excellent dew condensation preventing property in an outdoor sash structure in which the upper surface of the lower frame is formed substantially flat. It is to provide a heat insulating structure.

The upper surface member was attached to form a substantially flat upper surface of the lower frame, and the upper member for the inner sash was formed of a heat insulating material such as a resin.

[0008] By forming the upper member for the inner shroud with a heat-insulating material such as resin as shown in FIG.
In the heat-insulated line of the sash, it is located outside, and in the air-tight and water-tight lines, the heat conduction of the portion located indoors can be cut off, and when the outside air temperature is low, dew condensation can be prevented.

In the present invention, the purpose is to block the heat conduction of the portion located in the room and to prevent dew condensation and the like. In the sliding door that slides open and close the upper surface of the lower frame of the outdoor sash, the lower frame base member is configured by connecting the outdoor side base member and the indoor side base member with a heat insulating connecting member, The upper surface member for the outer sash and the upper member for the inner sash may be attached to the frame base member using a heat-insulating material such as a resin or separately, and the lower frame upper surface may be formed substantially flat. Needless to say, the entire lower frame may be formed of a heat-insulating material such as a resin, but it is difficult to secure the strength and the cost is high.

[0010] Further, when the surface portion of the upper member for the inner sash or the outer member of the outer sash made of resin or the like is formed by a separate piece member using a wear-resistant material such as an aluminum alloy extruded material or a SUS plate material, Abrasion scratches and the like due to the opening and closing of the shoji are less likely to occur. In other words, the purpose is to use a metal material or resin material that is harder than the material of the sliding door roller as the surface portion of the upper surface member that touches the sliding door roller.

[0011] The external,
When both the inner member and the upper member are attached to the outdoor base member side, the outdoor base member can be integrally formed into a cross-sectional shape having a hollow portion by using an aluminum alloy extruded material, and the strength is also improved. Excellent.
