BACKGROUND OF THE INVENTION
The present invention relates to a heat insulating sash material formed by combining an aluminum extrusion mold material and a resin mold material.
[0002]
[Prior art]
Conventionally, a heat insulating sash material formed by joining an aluminum extrusion mold material and a resin mold material is known. This type of heat-insulating sash material is used for sash frames and sash rods. Usually, an aluminum extrusion mold material is disposed on the outdoor side, and accordingly, a resin mold material is disposed on the indoor side. With this resin mold material, heat transfer from the aluminum extrusion mold material or heat transfer to the aluminum extrusion mold material is prevented, so that condensation does not occur indoors, or indoor heat insulation and cooling are maintained.

The resin mold material is bonded to the aluminum extrusion mold material by providing an engagement groove in the aluminum extrusion mold material and mounting the resin mold material on the aluminum extrusion mold material, or conversely by providing the engagement groove in the resin mold material and joining the aluminum extrusion mold material. An appropriate structure is adopted.
[0004]
[Problems to be solved by the invention]
Since this type of heat-insulating sash material constitutes a sash material that is integrated by combining an aluminum extrusion mold material and a resin mold material, the aluminum extrusion mold material and the resin mold material are bonded in close contact. However, since the aluminum extrusion mold material and the resin mold material have different coefficients of thermal expansion, the heat-insulating sash material formed by bonding in a tight manner has a problem of causing a warp phenomenon over time.
[0005]
The present invention has been made in view of the above problems, and an object of the present invention is to provide a heat insulating sash material that does not cause a warp phenomenon in a heat insulating sash material formed by combining an aluminum extrusion mold material and a resin mold material. To do.
[0006]
[Means for Solving the Problems]
The present invention relates to a heat insulating sash material formed by combining an aluminum extrusion mold material and a resin mold material. The aluminum extrusion mold material and the resin mold material each have two engaging portions on the aluminum extrusion mold material and the resin mold material. It is formed along the longitudinal direction, and has two engagement portions formed by engaging the engagement portion of the aluminum extrusion mold material and the engagement portion of the resin mold material, and one of the aluminum extrusion mold materials The engagement portion includes an extrusion groove formed by extrusion, and the engagement portion of the resin mold material is inserted into the engagement groove, the engagement groove is crimped, and the aluminum extrusion mold material is further formed. And the other engagement portion of the resin mold member is a heat insulating sash material having an engagement gap formed between both engagement portions when both engagement portions are engaged.
[0007]
The aluminum extrusion mold material and the resin mold material are engaged and coupled at the two engagement portions. Even if the both mold materials have some expansion due to the difference in thermal expansion coefficient, the both mold parts are brought into a non-separated state by caulking coupling between the engagement groove of the aluminum extrusion mold material and the engagement portion of the resin mold material. The difference in thermal expansion of the mold material is adjusted by the engaging portion having the engaging gap. In other words, even if a position shift occurs in the other engagement part due to the difference in thermal expansion between both mold materials, there is an engagement gap, so that one engagement part of the mold material forcibly presses and extends the other engagement part. Can prevent the deformation of the mold material.
