Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for manufacturing a heat insulating sash bar that constitutes window frames, glass doors, shutters, shoji frames, etc. The present invention relates to a method for manufacturing a heat insulating sash bar formed by connecting the sash bars.

Conventionally, the manufacturing method for this type of heat insulating sash bar involves molding the indoor side member and the outdoor side member separately, and placing the indoor side member and the outdoor side member facing each other with a gap between them to form a space. A manufacturing method in which a heat insulating material made of a thermosetting synthetic resin or a heat insulating material made of a foamed synthetic resin is injected and connected into the space, or an indoor member and an outdoor member placed opposite each other. A connecting member made of a heat insulating material is loosely fitted across the
A manufacturing method is known in which a foaming synthetic resin insulation material is then injected and connected.

However, no matter which manufacturing method is used, it is difficult to accurately connect the indoor side member and the outdoor side member to predetermined dimensions.

This is because when injecting and filling the insulation material, the indoor and outdoor members are not connected and fixed to each other, and in the latter method, the indoor and outer members are loosely fitted to the connecting member, so they may move slightly relative to each other. This is because it will be put away.

In addition, in the latter method, for example, JP-A-51-11
As shown in Japanese Patent No. 3339, a pair of connecting members is loosely fitted across both widthwise sides of the indoor side member and the outdoor side member,
Since a space is formed between the pair of connecting members and the indoor/outside member, and a heat insulating material is injected and filled into this space to form a heat insulating sash bar, the pair of connecting members are exposed to the outside.

For this reason, if rainwater or the like penetrates into the gap created at the loosely fitting part between the connecting member and the indoor/outside member and freezes, the loosely fitting part between the connecting member and the indoor/outside member may be damaged. ,
The strength of the heat insulating satsushi bar becomes weak.

The present invention has been made in view of the above circumstances, and its purpose is to accurately connect an indoor side member and an outdoor side member to a predetermined dimension via a heat insulating material, and also to connect a heat insulating connecting member and an indoor/outside member. To provide a method for manufacturing a heat insulating sash bar that prevents rainwater etc. from penetrating into the fixed part of the sash bar.
