Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a heat insulating panel joining apparatus used as a wall panel, a roof panel, or a floor panel when building a building.

[0002]

2. Description of the Related Art As a conventional bonding apparatus for a heat insulating panel of this type, as shown in FIG. 3, a ridge formed by sandwiching two pieces of wood 53 having a rectangular cross section on the side surface of one heat insulating panel 51 and a plywood 54 therebetween. Piece
55, and a concave groove 58 is formed on the opposite side of the other heat insulating panel 52.
After the convex strip 60 is fitted into this concave groove, the convex strip and the face material 61 of one of the heat insulating panels 51 are stopped by a fastener 62 such as a nail, or as shown in FIG. As both insulation panels 7
Grooves 73 for mating piece fitting on opposite sides of 1, 72
Is formed so as to be adjacent to the face material 75, and a joining piece 77 made of plywood or the like is fitted into the groove, and then the joining piece and the face material 75 of the heat insulation panels 71 and 72 are fixed with a fastener such as a nail. It was known what stopped at 78.

[0003] By the way, as in the joining apparatus shown in Fig. 3 described above, a projecting strip 55 mainly made of wood 53 is fitted and joined into a concave groove 58, and there is no heat insulating material at the joining portion. panel
Since the heat insulating materials 56 and 57 of 51 and 52 are cut at this joint, there is a problem that the heat insulating performance is impaired at the joint. Also, as shown in FIG. 4, a joining device in which a joining piece 77 is fitted into a concave groove 73 and joined, as shown in FIG.
You have to prepare two pieces each on the inside and outside face 75 side of 72,
In addition, two joining pieces 77 must be prepared, which requires a lot of time and effort in their manufacture, and in addition to poor workability at the site, there is a problem that the joining strength of the joint tends to be insufficient and weak. .

[0004]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems of the prior art, has a small decrease in heat insulation at the joint, is relatively easy to manufacture, and has a low workability on site. It is another object of the present invention to provide a heat insulating panel bonding apparatus having high bonding strength at a bonding portion.

[0005]

In order to achieve the above-mentioned object, the present invention provides a heat insulating panel joining apparatus comprising: a plurality of heat insulating panels in which heat insulating materials are sandwiched between inner and outer surfaces by sandwiches; In the device that joins the opposing side surfaces, a concave groove is formed on the opposing side surface of the heat insulating panel, which is formed by the inner surface of the inner and outer face materials and the end surface of the heat insulating material. The heat insulating strip sandwiched between the face materials is fitted, and the surface material of the heat insulating strip and the surface material of both heat insulating panels that overlap inward and outward by this fitting are stopped with fasteners such as nails. It is characterized by becoming.

[0006]

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a partially omitted, partially broken front view showing a joining device of a plurality of heat insulating panels arranged in series, and FIG. 2 is an enlarged plan view thereof. In both figures, reference numeral 1 denotes one heat insulating panel, and 2 denotes the other heat insulating material. Heat insulating materials 3, 4 are sandwiched from inside and outside by face materials 5, 6, 7, 8 such as plywood. I have. On the opposite side surface of the heat insulating panel 1 to be joined, a concave groove 10 composed of the inner surfaces of the inner and outer surface materials 5 and 6 and the end surface of the heat insulating material 3 is formed over the entire side surface. In addition, a concave groove formed by the inner surfaces of the inner and outer face materials 7 and 8 and the end surface of the heat insulating material 4 is also provided on the opposite side surface to which the heat insulating panel 2 is joined.
11 is formed over the entire side surface.

Reference numeral 13 denotes a heat insulating strip formed to have a size that can be fitted between the concave grooves 10 and 11, and, similarly to the heat insulating panels 1 and 2, heat insulating material 14 is provided from inside and outside to face materials 15 and 16 such as plywood. It is sandwiched in a sandwich. The thickness of each of the face materials 15 and 16 is the same as that of the face materials 5, 6, 7 and 8, and the heat insulating material 14 is naturally thinner than the heat insulating materials 3 and 4. In other words, the size of the circumference of the heat insulating strip 13 is set between the concave grooves 10 and 11 in a state where the heat insulating panels 1 and 2 face the opposite side surfaces of the surface materials 5 and 6 and the surface materials 7 and 8 as shown in the drawing. The dimensions are such that they fit exactly. Thus, the heat insulating strip 13 is fitted and arranged between the concave grooves 10 and 11 of the heat insulating panels 1 and 2, and the face material 15 of the heat insulating strip 13 and the heat insulating panel 1 The face materials 5 and 7 of 2 and the face material 16 of the heat insulating strip 13
The heat insulating panels 1 and 2 and the face materials 6 and 8 are fixed with fasteners 17 such as nails.

According to the above-described joining apparatus, the heat insulating materials 3, 4, and 14 are continuous at the joining portions of the heat insulating panels 1 and 2, so that the heat insulating property is improved and the conventional wood is mainly used. The heat insulating property does not decrease as in the case where the convex strip 55 is interposed. Also, at the time of joining, after the one heat insulating strip 13 is fitted, the face materials 15 and 16 of the heat insulating strip and the face materials 5, 6, 7 and 8 of both heat insulating panels 1 and 2 are stopped by the stopper 17. In this case, the on-site construction is extremely easy, and the manufacture of the heat insulating panels 1 and 2 and the heat insulating strip 13 has a relatively similar structure. In addition, even if it is stopped with the stopper 17, the face material of the same material is stopped so that it does not drop in strength, and the joining strength at the joint between the heat insulating panels can be sufficiently maintained.

A plurality of heat insulating panels 1 and 2 shown in this embodiment are sequentially arranged in series by the above-described joining device when building a building. , Roof panel, or floor panel. In addition, the dimensions, shapes, and the like of the members in the embodiment are merely examples, and it goes without saying that other designs other than those illustrated may be used.

[0010]

According to the present invention, as described above, grooves are formed on the opposing side surfaces of the heat insulating panel and are formed by the inner surface of the inner and outer surface materials and the end surface of the heat insulating material. Insulation strips sandwiched in a sandwich shape are fitted with each other, and the face material of the heat insulation strips and the face materials of both heat insulation panels that overlap inward and outward by this fitting are stopped with fasteners such as nails. Therefore, a decrease in heat insulation at the joint can be extremely reduced as compared with the conventional one. In addition, its manufacture is relatively easy, the on-site construction is extremely easy, and the workability can be significantly improved. In addition, there is an excellent effect that the joining strength at the joining portion between the heat insulating panels can be sufficiently maintained without decreasing.
