It is formed to extend continuously in the longitudinal direction of the material.

FIGS. 2 to 6 show a connecting unit 13 used in an embodiment of the present invention, in which a pair of connecting pieces 6 are arranged opposite to each other with a gap between them, and on opposite sides thereof, A slope 7 is formed that is inclined with respect to the longitudinal direction of the connecting piece 6, and the slope 7 has projections and recesses for preventing slippage consisting of a large number of protrusions extending in the width direction of the connecting piece 6, and each facing connecting piece 6 A wedge-shaped space 14 is formed by the slope 7 of the connecting piece 6, and two locking grooves 15 into which the locking flanges 2 of the connecting grooves 3 and 5 are to be fitted are formed on the plane opposite to the slope 7 of each connecting piece 6. The connecting piece is provided to extend in the longitudinal direction, and on both sides of the tightening wedge 9,
A slope 8 is formed that is inclined with respect to the longitudinal direction of the tightening wedge 9, and the slope 8 has projections and depressions for preventing slippage consisting of a large number of protrusions extending in the width direction of the tightening wedge 9,
In addition, a positioning protrusion 16 extending in the longitudinal direction of the wedge is integrally provided in the widthwise center of each slope 8,
Furthermore, a positioning groove 17 into which the positioning protrusion 16 is to be fitted is provided in the center of the slope 7 of each connecting piece 6 so as to extend in the longitudinal direction of the wedge, and a positioning groove 17 is provided on the thin wall side of the tightening wedge 9. The end portion is located at the wide end of the wedge-shaped space 14. The thicker inner end of each connecting piece 6 is connected via a thin groove-shaped connecting plate 18 that is easily deformable, and the thinner end of one of the connecting pieces 6 and the thinner end of the tightening wedge 9 are thinner. The connecting unit 13 is integrally molded in advance from a heat insulating material such as synthetic resin, and the connecting grooves 3 and 5 are connected to each other via a connecting plate 19.
In order to facilitate the fitting and insertion of the coupling grooves 3 and 5, the outer dimensions of the fitting portion of the coupling unit 13 into the coupling grooves 3 and 5 are made slightly smaller than the inner dimensions of the coupling grooves 3 and 5.

FIGS. 7 to 14 show an embodiment of the present invention. First, as shown in FIGS. 7 and 8, the connection groove 3 of the indoor frame member 1 constructed as described above and the connection grooves 5 of the outdoor frame material 4 are arranged so as to face each other in parallel, and each connection piece 6 in the connection unit 13 configured as described above is fitted across each connection groove 3, 5. At the same time, the locking grooves 15 of each connecting piece 6 are fitted into the locking flanges 2 of the connecting grooves 3 and 5, and in this state, the connecting unit 13 is moved to a predetermined position in the longitudinal direction of the frame material, and then As shown in FIG. 9, each connecting piece 6 is pressed from the direction of arrow C, and the tightening wedge 9 is press-fitted into the wedge-shaped space between each connecting piece 6 from the direction of arrow D, and as shown in FIGS. As shown in FIG. 3, the tightening wedge 9 is press-fitted to a position where it completely or almost completely overlaps each connecting piece 6, and the tightening surfaces 20 on both sides of each connecting piece 6 fit into the grooves of each connecting groove 3, 5. It is pressed against the side. Note that when the tightening wedge 9 is strongly pressed toward the wedge-shaped space 14, the connecting plate 19 is automatically cut, and the connecting pieces 6 are moved in the direction away from each other by press-fitting the tightening wedge 9. Then, the channel-shaped connecting plate 18 is extended or cut.

Thereafter, in the same manner, the required number of connecting units 13 are sequentially fitted across the respective connecting grooves 3 and 5 and moved in the longitudinal direction of the frame material to a predetermined position, and the wedge-shaped connecting pieces 6 in each connecting unit 13 are formed. A tightening wedge 9 is press-fitted into the space, and the sealing groove formed by the sealing member supporting protrusions 11 and 12, the groove-shaped portion between the groove side plates of the connecting grooves 3 and 5, and one connecting piece 6 is inserted into the sealing groove. A sealing material 21 made of silicone rubber, synthetic rubber, or other heat-insulating material is inserted into the
A heat insulating frame material for a sash is constructed as shown in FIGS. 12 and 13.

The insulation frame material constructed in this way is cut at appropriate lengths at both ends (diagonally cut at a 45° angle).
Four heat insulating frame members with both ends cut (obliquely cut) are arranged to form a rectangle, and the joints (corner parts) of the ends of each heat insulating frame member are connected to each other. As the coupling means, a means of fitting an L-shaped connector into the hollow hole 10 and fixing it by caulking or screws may be adopted, or a fixing means by welding may be adopted.

FIG. 14 shows a part of a shoji door using the heat insulating frame material of the above embodiment, in which 22 is glass, 23 is a glass liner, and 24 is a sealing material.

When carrying out this invention, each connecting piece 6 and the tightening wedge 9 may be manufactured separately from each other without being connected by the connecting plates 18 and 19; however, as in the above embodiment, each connecting piece 6 and the tightening wedge 9, the connection plate 18,
If connected via 19, the connection unit 13
While the connecting pieces 6 and the tightening wedges 9 constituting the connecting unit are inserted into the respective connecting grooves 3 and 5 to predetermined positions,
Since the two do not separate, the work of inserting and inserting the connecting unit can be carried out easily and quickly.

The tightening wedge 9 may be made of metal such as aluminum, but in this case, in order to prevent the tightening wedge from coming into contact with the frame materials 1 and 4, the tightening wedge 9
It is necessary to make the width of the connecting piece 6 slightly smaller than the width of the connecting piece 6.

According to this invention, the connecting groove 3 in the shape of an outward opening groove having the locking flanges 2 protruding in the direction toward each other is formed on the outside of the indoor frame material 1 so as to extend in the longitudinal direction of the frame material. On the inside of the outdoor frame material 4, an inward opening groove-shaped connection groove 5 having locking flanges 2 protruding in the direction toward each other is formed so as to extend in the longitudinal direction of the frame material, and each of the connections A heat insulating connecting piece 6 is fitted across one widthwise side of the grooves 3 and 5, and a heat insulating connecting piece 6 is fitted across the other widthwise side of each of the connecting grooves 3 and 5. The connecting grooves 3 and 5 are formed in the mutually opposing portions of each connecting piece 6.
A slope 7 inclined with respect to the longitudinal direction of the connecting piece 6 is provided in the wedge-shaped space formed by the slope 7 of each connecting piece 6.
Since the tightening wedge 9 having the slope 8 that engages with the slope 7 is press-fitted from the longitudinal direction of the connecting groove, the indoor frame material 1 and the outdoor frame material 4 can be connected by simple means. The slope 7 of the connecting piece 6 can be firmly insulated and connected in a stable state so as not to move relative to the outside of the room and in the direction of the connecting groove width.
Since the slope 8 of the tightening wedge 9 is provided with a large number of projections and depressions for preventing slippage extending in a direction perpendicular to the longitudinal direction of the connecting groove, there is no possibility that the tightening wedge 9 will slip out from between the connecting pieces 6 after the adiabatic connection. Effects such as being able to eliminate the problem can be obtained.
