Description

[Detailed Description of the Invention] The present invention relates to a heat insulating material which is formed by integrally connecting and molding a pair of metal members with synthetic resin, and which is mainly used as a shape material such as aluminum sash.

In recent years, it has been considered to use a heat insulating material that combines a metal member and a synthetic resin for the purpose of heat insulation and prevention of condensation for frames and frames such as aluminum sashes. However, even though synthetic resins have a high heat insulating function, they have weaker strength than metal members, so a large amount of the material must be used, resulting in high manufacturing costs. are doing.

In order to achieve the above object, the present invention provides a heat insulating material formed by integrally connecting and molding at least a pair of metal members with a synthetic resin material, by inserting the pair of metal members into a composite extruder and forming the synthetic resin The metal member and the synthetic resin material are integrally connected by composite extrusion molding, and the pair of metal members are non-hollow and form parallel plate-shaped portions, and at least one of the metal members has a pair of metal members. forming a linking protrusion of
A synthetic resin material is provided between the plate-shaped parts, and the synthetic resin material includes a plurality of connecting molded parts that connect the two plate-shaped parts, a backbone that connects the connecting molded parts together, and the connecting molded part and a covering part that continuously covers at least one outer surface of the plate-shaped part, and the connecting molded part of the synthetic resin material overlaps with the connecting protrusion piece of the metal member, and the backbone has a covering part that covers the outer surface of at least one plate-like part, and the connecting molded part of the synthetic resin material overlaps with the connecting protrusion piece of the metal member. By partitioning and separating the tip of the metal member from the other metal member, it is possible to achieve insulation and prevent condensation with an extremely simple structure, reducing the number of manufacturing steps. This paper proposes a heat insulating material that can be firmly bonded and supported by materials.

Hereinafter, embodiments of the present invention shown in the drawings will be described in detail. FIG. 1 is a cross-sectional view of a heat insulating material according to a first embodiment, and this first embodiment shows the upper stile of a glass shoji screen.

In the figure, the heat insulating material of this embodiment is formed by integrally connecting and molding at least a pair of metal members 1 with a synthetic resin material 2, and the pair of metal members 1 have parallel plate-like parts 3A and 3B. This plate-shaped portion 3A,
3B, a synthetic resin material 2 having a plurality of connecting molded parts 4, 4 and a backbone 5 that connects them together is provided.

The pair of metal members 1 forming the parallel plate portions 3A and 3B are non-hollow and are mainly formed from extruded aluminum sections. On the other hand, the synthetic resin material 2 having the connecting molded parts 4, 4 and the backbone 5 is molded from a synthetic resin such as vinyl chloride resin or acrylic resin, for example.
The synthetic resin material 2 is integrally connected to the metal member 1 at the same time by inserting the aluminum extruded shape into a composite extruder and performing composite extrusion molding with the resin material. By the above molding, the plate-like parts 3A, 3 are formed simultaneously with the molding of the synthetic resin material 2.
B can be connected, facilitating molding of the heat insulating material, and the plate parts 3A and 3B can be firmly connected. Further, by making the metal member 1 non-hollow, the structure of the composite extrusion die can be simplified, and composite extrusion molding can be easily performed.

Plate-shaped portion 3 constituting the pair of metal members 1
A and 3B are made to face each other in parallel with a predetermined interval. Moreover, the plate-like parts 3A and 3B are formed to have a normal thickness suitable for the upper stile of a glass shoji.

One of the plate-shaped parts 3A and 3B is the outdoor side member 3A
, and the other indoor side member 3B is attached inside this.
A pair of interlocking protrusions 7, 7 protruding in parallel toward
is provided. The opposing inner sides of these plate parts 3A and 3B, and the connecting molded part 4 of the synthetic resin material 2,
4 is provided with engaging portions 8, 8 that engage with the concave and convex portions, respectively, and these engaging portions 8, 8 engage the metal member 1.
The integral connection between the synthetic resin material 2 and the synthetic resin material 2 is further strengthened. The metal member has a pair of plate-like parts 3A and 3B.
An auxiliary member may be provided in addition to the above.

On the other hand, the connecting molded parts 4, 4 constituting the synthetic resin material 2 are located between the plate-like parts 3A, 3B of the metal member 1, and are arranged in a pair of parallel molded parts so as to connect them with a predetermined interval. It is formed from a plate-like body. The thickness of this plate-like body is slightly thicker than that of the plate-like parts 3A and 3B. In addition, the connecting protrusions 7, 7 of the plate-like part 3A, which is the outdoor side member, are overlapped and brought into close contact with each inner side of the pair of connecting molded parts 4, 4, thereby making the plate-like part 3A and This has further strengthened the connection between the two. Since the pair of metal members 1 are separated from each other by the connecting molded portion 4 and do not come into contact with each other, adiabatic dew condensation can be prevented between the indoor and outdoor facing portions during use. Note that the number of connecting molded portions 4, 4 is not limited to one pair, but may be any plural number.

Further, the outer surface of the other plate-shaped portion 3B is covered with a covering portion 6 of the synthetic resin material 2 so that the metal member 1 is not exposed on the outer surface at all. With this configuration, when the plate portion 3B is located on the indoor side, further prevention of dew condensation can be achieved. The thickness of the covering portion 6 may be thinner than that of the plate portion 3B since there are few problems in terms of strength. Further, the covering portion 6 is integrally molded with the connecting molded portions 4, 4 at the same time.

The plurality of connected molded parts 4, 4 described above are integrally linked by providing a backbone 5 between the opposing parts. This backbone 5 maintains a strong connection between the connecting molded parts 4, 4, and eliminates wasteful use of a large amount of resin material by making it unnecessarily thick. This backbone 5 spans approximately the center of the connecting molded portions 4, 4, and has an overall approximately H-shaped cross section, and this shape further improves the support strength of the plate-shaped portions 3A, 3B. In addition, the backbone 5 partitions and separates the tips of the interlocking protrusions 7 and the other metal member 1 (on the right side in the figure), eliminating direct contact between the metal members 1 and 1, and providing heat insulation. It's starting to be effective.

Note that the number of backbones 5 is not limited to one, and a plurality of backbones 5 may be provided between the connecting molded parts 4, 4. When a plurality of them are used, a hollow part is formed between the connected molded parts 4, 4, and further support strength can be obtained.

The above-mentioned plate-like parts 3A, 3B and connection molded parts 4, 4
Hollow portions 10A and 10B partitioned by the backbone 5 are formed in the intermediate portion surrounded by. These hollow portions 10A and 10B improve the torsional and bending strength of the entire heat insulating material.

Note that the plate-like parts 3A and 3B that constitute the metal member 1
The upper end portions of each form a stepped portion 11, 11,
It is used as an airtight material contacting part when used as a shoji upper frame. Also, there is a screw hole 9 on the inside of the connecting protrusion 7.
is provided. For example, a panel made of glass or the like is mounted in the recess 12 formed between the plate-shaped parts 3A and 3B.

FIG. 2 is a cross-sectional view of the second embodiment, and this figure shows the lower stile of the glass shoji. In this figure, the same parts as in the first embodiment are indicated by the same reference numerals.

Since this figure shows the lower stile as an example, it has an overall rectangular cross-sectional shape compared to the embodiment of FIG. 1, and the other basic configurations are the same.

In the figure, a stepped portion 11 serving as an airtight material abutting portion is formed at the lower end of one of the plate portions 3B. Moreover, the upper end recess 1 formed between the plate-like parts 3A and 3B.
2 is fitted with a panel such as glass, and the lower end recess 13 is fitted with a door roller, for example.

As described above, the present invention forms parallel plate-shaped parts on a pair of metal members, and molds them so as to integrally connect them with a plurality of connecting molded parts made of synthetic resin material. Heat transfer is cut off between the metal members to prevent adiabatic condensation, and integral molding simplifies the structure and reduces manufacturing costs.

In addition, since the present invention is constructed from a composite extrusion molded material, it is possible to further reduce the manufacturing process mentioned above.
Moreover, since the pair of metal members are made non-hollow, the composite extrusion mold can be simplified and manufactured easily.

Furthermore, the rigidity of the integral connection can be achieved by overlapping the connecting molded part of the synthetic resin material with the connecting protrusion piece of the metal member, and in addition, the backbone that integrally connects the connecting molded part is formed on the connecting protrusion piece of the metal member. Since the tip and the other metal member are partitioned and separated, a non-contact part is formed between the metal members at the linking part of the synthetic resin material that integrally connects the pair of metal members. Therefore, the heat transfer blocking effect between the pair of metal members can be further improved.

In addition, since we decided to provide a covering part that connects to the connecting molding part and covers the outer surface of at least one of the plate parts, it is possible to prevent the metal member from being exposed on the outer surface and further prevent dew condensation. There is an effect that it can be done.
