[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method of coating a surface of a plate material as a building material mainly composed of cement with a surface material to form a composite, without using an adhesive. The present invention relates to a joint member of a composite panel that can be securely engaged even with the joint panel.

2. Description of the Related Art Architectural interior / exterior plate materials in which an extruded panel is used as a base material and tiles or the like are adhered to the surface thereof are used. In recent years, as a surface material of such an interior / exterior material, a material to which a long tile is attached has been used. When such a base material and a surface material are integrated to form a composite panel, grooves for positioning each other are provided and bonded with an adhesive. On the other hand, as shown in Japanese Utility Model Publication No. 1-24277, a dovetail groove is provided in the longitudinal direction of a contact surface between a base material and a surface material covering the base material as a technique for mounting a small tile. There is a composite material that slides along and is fixed with an adhesive.

[0003]

[Problems to be solved by the present invention]
According to the technology disclosed in Japanese Patent No. 77, it is necessary to slide the surface material along the groove of the base material. However, in the case of a long plate, it takes time and effort to slide from the end to the center, which is inefficient. Was. In order to solve this problem, the present applicant discloses in Japanese Patent Application No. 3-319348 a composite panel having a high work efficiency, a surface material being securely fixed to a surface material, and no risk of falling of the surface material, and a method of manufacturing the same. Disclosed. Japanese Patent Application No. 3-
No. 319348 discloses FIGS. 3 (a), (b), (c),
As shown in (d), the surface material 2 is attached to the dovetail shape 1a of the base material 1.
Is a composite panel in which the base material 1 and the surface material 2 are integrated by engaging the dovetail shape 2a, widening the two surface materials 2 in the direction of the arrow, and applying a joint material 4 in a gap therebetween.

The present invention relates to a joint panel member for a composite panel which can be suitably used in Japanese Patent Application No. 3-319348 and which can securely fix a surface material and a base material without necessarily using an adhesive. The task is to provide.

[0005]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems, and is applied to a joint member of a composite panel in which a dovetail of a base material and a surface material are engaged and fixed by joints. Measures were taken. That is, a joint member for a composite panel, comprising a metal fitting having a widened portion that widens in the joint width direction when screwed to a base material.

[0006]

The operation of the present invention will be described with reference to FIG. FIG.
1A is a perspective explanatory view of one embodiment, and FIG. 1B is an explanatory view in which a base material 1 and a surface material 2 are integrated according to this embodiment. The joint member of the present invention includes a metal fitting 10 provided with a hole 4a made of an elastic material and a screw 4 for screwing the metal fitting.

As shown in FIG. 1 (b), when the screw 4 is tightened, the metal fitting 10 is pressed and widened, the surface material 2 is pressed in the direction of the arrow, and the dovetail 1a of the base material 1 and the surface material 2 are pressed. Ant Form 2
a is engaged. After the engagement, the joint material 3 can be applied from above the screw 4 and the metal fitting 10 to form a composite panel. According to the present invention, the base material 1 and the surface material 2 can be completely integrated into a composite panel without using an adhesive.

[0008]

FIG. 2 shows each embodiment of the present invention. The left side of the drawing shows a state before the metal fitting 10 is screwed, and the right side shows a state where the metal fitting 10 is widened by screwing. FIG. 2A shows the same bracket as FIG. 1A. FIG.
(B) is to widen the width with the washer 5 by screwing. FIGS. 2C and 2D show a combination of a sphere and a truncated cone. FIGS. 2 (e) and 2 (f) show that the metal fitting is widened by the head of the screw when tightening the screw. FIG.
(F) is an embodiment having a spring shape different from that of FIG. 2 (a).

An example in which a composite panel is constructed using the metal fitting of the present invention will be described. Cement-based extruded base material 1 having a length of 2000 mm and a width of 600 mm is provided with a length of 1980 mm and a width of 290 mm.
2 mm ceramic surface material 2 was engaged to form a composite. Then, the base material 1 at the center is joined to the joint 3 (width 10 mm).
A 2 mm diameter hole is made in the SUS306 steel fitting 10
Was attached to the joint part 3, and the metal fitting 10 was tightened with a tapping screw having a diameter of 3 mm and a length of 20 mm. Three locking fittings were used for the joint portions 3 of the pair (two) of the surface materials 2. Although no adhesive was used for this composite panel, the base material 1 and the surface material 2 could be firmly locked. The joint 3 was treated with a commercially available silicone sealant.

The material of the metal fitting of the present invention is the above, elastic material or solid material.
Any material may be used as long as it is pressed in the direction of the arrow in (b), and a material such as a metal spring, stainless steel, brass, or plastic can be used. Also, the shapes are shown in FIGS.
The shape or the structure is not limited to (f) but may be any shape or structure as described above, in which the width is increased by the screwing pressure and the surface material 2 is pressed in the direction of the arrow in FIG.

[0011]

[Effects of the Invention] The present invention has the following excellent operational effects. (1) When a composite panel is manufactured by integrating a base material and a surface material, it is not always necessary to use an adhesive, so that it is possible to employ a completely dry-type construction method, thereby simplifying work and improving work efficiency. .

(2) When an adhesive is used, there is a danger that the adhesive will deteriorate over time and the surface material will fall off. However, in the present invention, such an accident is completely eliminated. (3) Adjustment of the joint width, which was difficult in the past, can be performed from the surface material side. In addition, after fastening the screw, the metal fitting is buried by the joint treatment, so that the appearance is not spoiled.
