Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sassive bar that constitutes a window frame, a glass door, a shutter, a frame of a shoji screen, etc. The present invention relates to a method for manufacturing a heat insulating sash bar in which an indoor wall, ie, one side wall, and an outdoor wall, ie, the other side wall of the sass bar are connected via a heat insulating material in order to prevent the air from radiating into the room.

Conventionally, there are various methods for manufacturing this type of heat insulating sash bar. For example, one side wall and the other side wall constituting the sash bar are manufactured separately in advance, and the two side walls and the other side wall are connected with a heat insulating material. Alternatively, a main body having a substantially U-shaped cross section is manufactured by connecting the longitudinal side ends of one side wall and the other side wall constituting the sassive bar with a connecting wall, and after filling the main body with a heat insulating material, the connecting wall However, in the former case, when connecting the H side wall and the other side wall with a heat insulating material, not only must the H side wall and the other side wall be placed opposite each other at a predetermined interval, but - There is a problem that the side wall and the other side wall may shift and move, making it impossible to manufacture the desired heat insulating sash bar.In the latter case, the part where the connecting wall is cut and removed is not filled with heat insulating material and a recess is formed. Problems such as rainwater, garbage, etc. accumulating in the parts, not only prolonging the rain, but also making it unsanitary, or causing corrosion from the cut surfaces, etc.
When cutting the connecting wall, there is a problem in that the filled insulation material and the connecting wall are in close contact with each other, making the cutting process troublesome.

In addition, in the former 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,
A space is formed between the pair of connecting members and the indoor and outer members, and a heat insulating material is injected and filled into this space to form a heat insulating sash bar, so that 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 portion between the connecting member and the indoor or outer member, and freezes, the loosely fitting portion between the connecting member and the indoor or outer member may be damaged. , the strength of the heat insulating sash bar becomes weak.

As described above, in any case, conventional methods of manufacturing heat insulating sash bars have not always been satisfactory.

The present invention has been devised in view of the above circumstances, and provides a method for manufacturing a heat insulating sash bar that eliminates the above-mentioned conventional problems and can easily and accurately produce a desired heat insulating sash bar. The purpose is to

In addition, the width t is narrower than the length that fits between the connecting wall 4 and the protruding pieces 13, 14, that is, the width of the one side wall 2 and the other side wall 3 of the main body 1, and further, Notch grooves 25 and 26 are cut in the opposite corners of the main body 21 from the first protrusion 23 and the second protrusion 24 in the longitudinal direction, and
A plurality of holes 27 passing through the width direction are formed at predetermined intervals in the longitudinal direction, and one end of the name tag 27 is opened at the bottom 22a of the groove 22.

Next, the manufacturing method of the first embodiment as described above will be explained step by step with reference to FIG.

■ Insert the connecting member 20 from the longitudinal direction into the main body 1 shown in FIG. The second projection 23 of the member 20 is fitted between the inner surface 3a of the other side wall 3 of the main body 1 and the bent portion 10.

That is, the connecting member 20 fits into the widthwise intermediate portion of the -IIIJ wall 2 and the other side wall 3 of the main body 1.

[See Figure 2] At this time, since the protruding pieces 13 and 14 are inclined toward the flanges 5 and 6, the connecting member 20 can be easily fitted.

As a result, the pair of notch grooves 25 and 26 of the connecting member 20 face each of the protrusions 13 and 14.

■ Each protruding piece 13, 14 is bent toward the connecting member 20 side, and is fitted into the pair of notch grooves 25, 26 and caulked to form a connecting member across the widthwise intermediate portion of the one side wall 2 and the other side wall 3 of the main body 1. 2
0 is bridged, and the width direction of the connecting member 20 - side surface and one side wall 2
and the opening lower side portion of the other side wall 3, and the groove 22 of the connecting member 20 is continuous with the opening lower, that is, the other side space is formed between the other side in the width direction and the bottom 11 of the connecting wall 4. form each.
