Description

[Detailed Description of the Invention] The present invention relates to a heat insulating structural material that blocks heat conduction between indoors and outdoors.

In this specification, structural materials are those used as various members such as sash frames, shoji frames, blinds, orientations, door frames, door frames, and refrigerated showcases.

Conventionally, as shown in FIG. 1, this type of heat insulating structural material has been constructed by forming concave grooves 3 and 4 having locking claws 1, 1, and 2 degrees 2 at the openings, and facing each other with a connecting wall 5 in between. By aligning the grooves 3 and 4 in the opposite direction, a groove 6 for filling a heat insulating material is formed between both grooves 3 and 4, and an indoor part a and an outdoor part of arbitrary shapes are connected to each groove 3 and 4. The member A is extruded in advance and the heat insulating material 7 is injected into each of the grooves 3 and 4 from the groove opening 8 of the aluminum member A and cured, as shown in FIG. It is known that the aluminum member A is manufactured by cutting out the connecting wall 5 and dividing the aluminum member A into two parts, an indoor part a and an outdoor part. Since the metal inside the groove is filled with a synthetic resin type heat insulating material, it requires a lot of materials and has the problem of increasing product cost.

Therefore, the present invention aims to reduce the manufacturing cost of heat insulating structural materials, and while reducing the amount of synthetic resin heat insulating material used, it has sufficient strength and exhibits excellent heat insulation properties. For the purpose of providing thermal insulation structural materials,
The structure has a unique twist.

That is, the heat insulating structure material according to the present invention includes a pair of metal members in which grooves having locking claws in the openings face each other at a constant interval, and a pair of metal members interposed between the two members and integrally integrated. It consists of a heat insulating material that is connected to a single structural member, and a separately molded heat insulating partition wall material that is fitted into the groove to form a hollow part, and the hollow part is connected to the heat insulating material in the direction of heat conduction. It is characterized by being arranged side by side so as to overwhelm the heat insulating barrier layer.

Hereinafter, the present invention will be explained based on the illustrated embodiment. A pair of metal members 9 and 10, which are to be opposed to each other at a certain interval, are integrally extruded as extruded sections in a connected state in advance. As shown in FIG. 2A, one wall 13 forming the opposing grooves 11 and 12
．． 14 are integrally connected to each other by a connecting wall 15 and are extruded from an aluminum alloy.

By extrusion molding in this way, the double concave grooves 11, 1
A heat insulating material filling groove 16 is formed between the two grooves 11 and 12.
Opposing walls 13.13 a, 14.14 a that constitute
Partition wall material fitting grooves 17.17a and 18.18a are also provided in the .

The partition material 19.20 fitted into each of the grooves 11.12 is a sheet or plate-like material made of hard synthetic resin, and is molded separately from the extrusion-molded metal members 9, 10.

The partition wall material 19.20 is inserted into the fitting groove 17°17.
By fitting into the grooves 11.a and 18.18a, a hollow portion 21.22 is formed in each groove 11.12, as shown in FIG. 2A.

The following method is used to make the extruded shape B having the above structure into a heat insulating structural material.

That is, in the extruded section B that is integrally extruded, first,
The heat insulating material 23 is injected and filled into the heat insulating material filling groove 16 which is sandwiched between the partition wall materials 19 and 20 in each of the grooves 11 and 12, as shown in the opening in FIG.

As a result, after the heat insulating material 23 has hardened in the heat conduction direction (indicated by the arrow in the figure), the concave groove connecting wall 15 is cut away, and an opening is opened between the two metal members 9 and 10 as shown in FIG. 2C. Groove 24
It forms.

Although the extruded shape member B is divided into both metal members 9 and 10, the hardened heat insulating material 23 serves as the locking claws 25 and 25a at the openings of the respective grooves 11 and 12.

26 and 26a, the two metal members 9 and 10 maintain an integrally connected state and form a single structural member.

The heat insulating structure material manufacturing process may also be carried out as follows.

That is, as shown in FIGS. 3 to 5, the partition wall materials 19, 2
While conveying the extruded shape B with 0 fitted thereon by means of conveyance such as a conveyor, the cutter 2
At step 7, the connecting wall 15 is cut out to divide the extruded profile B into two parts, and the opening groove 24 created by this cutting process is immediately filled with adhesive tape 2.
8, while injecting and filling the new groove 16a formed by the closure with the heat insulating material 23,
The adhesive tape 28 is peeled off after the heat insulating material 23 is cured.

In addition, FIG. 6 shows another embodiment of the heat insulating structural material according to the present invention, in which a partition wall material 19 is fitted only in one groove 11, and the heat insulating barrier layer is insulated from the hollow part 21. It has two layers of material 23.

Further, FIG. 7 shows a case in which a hollow part 21 is formed in the groove 11 using a partition wall material 19 a having leg pieces 29 and 30 without providing any partition wall material fitting groove in the groove 11.12. It is something.

In the heat insulating structure material manufactured as described above, the hollow portions 21 and 22 and the heat insulating material 23 are lined up in the heat conduction direction to form a three-layer barrier layer, which is different from the conventional structure simply filled with heat insulating material. Compared to the conventional method, when configuring a heat insulating barrier part of the same size, it is possible to block heat conduction more effectively and to greatly reduce the amount of heat insulating material used.
This has the practical benefit of reducing costs.

In addition, when obtaining the same heat insulation effect as the heat insulation structural material of the conventional structure, the amount of heat insulation material used can be further reduced.

In particular, a major feature of the present invention is that the hollow portion is formed using a separately molded heat insulating partition wall material.

Conventionally, partition walls have been extruded together with metal members, but even if a hollow part is formed by integrally molding the partition wall with the same material, this hollow part is only meant to be reinforced, and has no effect on heat insulation. It is clear that this has no effect at all. On the other hand, since the partition wall material of the present invention is made of a separately molded heat insulating member, the heat conduction from the metal member to the partition wall material is Therefore, the hollow part itself is also provided with heat insulating properties, making it possible to form a three-layer heat insulating barrier layer as described above, which has a remarkable heat insulating effect compared to conventional ones. It is something that can be demonstrated.
