Description

[Detailed description of the invention] The present invention relates to a joint material used for window frames, shoji frames, etc. for cold regions, and in particular inserts a connecting material with low heat conductivity between two metal shapes. This relates to a heat insulating material in which both metal members are connected to each other.

In this kind of molding material, which has been known in the past, a synthetic resin is injected between the two metal molding materials to hold the two metal molding materials at an appropriate distance, and the two metal molding materials are integrated with this synthetic resin. , and after injecting a synthetic resin into the hollow part of a metal mold that has been integrally molded in advance and hardening it, the metal wall that makes up the hollow part is cut, and the mold is divided into two parts, etc. However, these had the following problems that should be improved.

In other words, in the conventional method, a resin such as a sealant is filled between two metal molds, so ■ there is no dimensional stability due to shrinkage as the resin hardens; It has been pointed out that peeling may occur due to differences in thermal expansion coefficients, which impairs the integrity and reduces strength; and (2) the watertight effect is also reduced due to poor adhesion.

In view of the above-mentioned drawbacks, the inventor of the present invention proposed that, in a molded material in which two metal molded materials are joined together by a connecting material inserted or filled between them, each of the joint surfaces of both metal molded materials is By providing a fitting groove formed by a pair of upper and lower projecting pieces that extend in opposite directions, and by crimping and fitting a specially shaped hard strip or piece with heat insulating properties into this fitting groove, two This project proposes a highly insulating mold material that is made by strongly bonding two metal mold materials.

Embodiments of the present invention will be described below with reference to the drawings.

In FIG. 1, numerals 1 and 2 indicate shapes made of a metal material such as aluminum or its alloy material, or steel material.

These molding materials 1 and 2 are molded separately in advance, and at that time, a pair of upper and lower protruding pieces 3.3 and 4, 4 are formed projecting from the joining surfaces of both molding materials in the longitudinal direction of the molding materials.

That is, the upper protruding pieces 3, 3 are, for example, hook-shaped pieces with a cut-off cross section, and the hook portions 3a are connected downwardly to the protruding pieces 4 below the waist.
．． 4 has an inverted T-shaped cross section and is provided with an upwardly protruding portion 4a.

After forming the fitting grooves 5, 5 for the connecting members described later between the protruding pieces 3, 4, respectively, in this way, the two molded members 1 and 2 are placed opposite each other at an appropriate distance and placed in the space where they face each other. ,
A connecting member 6 made of a hard heat insulating material is inserted.

The main body of this connecting member 6 is made of ABS resin with high heat insulation properties.
It is made of a generally T-shaped piece or elongated material made of a hard resin molded product such as vinyl chloride resin, and has sloped walls 7, 7, 8°8 extending outward on both the upper and lower sides of the connecting member 6. Engagement grooves 17 and 18 are formed (see FIG. 2).

In addition, a soft sealer is applied to the groove on the upper surface of the connecting member 6 to prevent rainwater from entering after the connecting member 6 is inserted into the mold.

FIG. 3' shows an example of a construction method for tightly adhering the connecting member 6 to the shapes 1 and 2.

In the figure, the upper protruding pieces 3, 3 of the molded members 1 and 2 are previously inclined upward during molding, so that the space of the fitting groove 5 is made larger than the connecting member 6 into which it is to be inserted.

After that, a connecting member 6 is inserted into the fitting groove 5 from one end of the mold material.
Insert as shown in Figure 3.

Next, a presser jig 11 is applied to the lower surface of the protruding piece 4, and then the inclined protruding piece 3 is pressed from above with a press 12.
The inclined wall 7 of the connecting member 9 is pressed by the hook portion 3a of the protruding piece.

In this way, the hook portion 3a and the protruding portion 4a and the inclined wall 7
, 8, force acts on the connecting member 6 in the direction of arrow A, and on the shapes 1 and 2 in the direction of arrow B.

As a result, the connecting member 6 is firmly attached to the shapes 1 and 2, and the shapes 1 and 2 are tightly connected to each other with the legs 13 of the connecting member in between.

Incidentally, since the spacing regulating leg part 13 is made to protrude between the opposing protruding pieces 3:, 3 and 4.4 from the engagement grooves 17 and 18, the shape members 1 and 2 that face each other with this leg part in between. The interval between is always constant.

The reason why the protruding pieces 3, 3 are inclined in FIG. 3 is to facilitate the insertion of the connecting member 6, but it is not necessary to make them inclined.

As mentioned above, the present invention is a combination of a molded material having a specially shaped fitting groove on the joining surface and a specially structured heat-insulating rigid connecting member. By fitting a heat insulating hard bolt into the fitting groove, the two molded members are mechanically and tightly fixed by this connecting member.

In the present invention, the shape of the connecting member 6 for connecting is not necessarily limited to the T-shape, and a cross-shaped overall shape 14 as shown in FIG. 4 may also be used. In addition, as shown in Fig. 5, a hollow part is provided inside the connecting member 1
It is also possible to use 5.

Since the present invention has a structure as shown in the above embodiment, if the heat insulating connecting member 6 is fitted into the fitting grooves 5, 5 of the two facing sections 1, 2, the two sections will be mechanically connected to each other by this connecting member. It has the advantage that it can be fixed easily and quickly to the mold, and there is no need to wait for time for it to harden after injecting the resin as in the conventional method, and since the two molds are separated by a heat-insulating connecting member, heat conduction is possible. is blocked.

Therefore, when the proposed profile is used as a window frame or shoji frame in a cold region, even if the outside temperature drops, the cooling of the outside air will not be transmitted to the indoor profile, so there is no risk of condensation forming on the indoor profile. There is also less heat escaping to the outside.

Further, according to the present invention, when the two shapes 1 and 2 and the connecting member 6 are joined together, after the connecting member 6 is fitted between the shapes 1 and 2, a presser jig is attached to the lower surface of the protruding piece 4. After applying pressure, the protruding piece 3 is pressurized from above to press the tip of the protruding piece 3 against the inclined groove 7, and by wedge engagement between the two, the connecting member 6 and both mold members 1 and 2 are mechanically brought into close contact. Since it is integrated, there is no need for assembly processing.

In addition, the protruding pieces β, 3 and 4 that face the interval regulating leg 13 are
, 4, the distance between the mold members 1 and 2 facing each other with the leg portions in between is always constant, and the thickness does not change over time.

Therefore, since the present invention has excellent dimensional stability, it is possible to provide a highly accurate fitting material.

Furthermore, a soft sealer 1 is applied to at least one of the engagement grooves 17 and 18.
0 is pasted to fill the gap between the engagement groove and the protruding piece, the only effect is that the connecting member 6 and the shapes 1 and 2 do not move relative to each other and are tightly integrated. First, it has the effect of preventing rainwater from entering the gap.
