The width of the ridge is narrower than the width of the concave ridge, and the spacer is interposed in the gap on the opposite side of the one side engaging side between the ridge and the ridge. It is a composite panel characterized by integrating a base material and a surface material. In the composite panel of the present invention, as shown in FIG. 6, spacers are formed in a wedge shape and attached in advance at positions where the contact surfaces of the base material and the surface material are opposed to each other, and the base material and the surface material are arranged in the longitudinal direction of the groove. The wedge may act as a spacer with a slight offset. In the manufacture of this panel, a first member (base material or surface material) having a dovetail-shaped groove and a ridge narrower than this groove are engaged with the groove of the first member. A second member (a surface material or a base material) is manufactured, and the first member and the second member are aligned in the direction in which the dovetails of the concave and convex lines are engaged, This is done by engaging the dovetails of the second member and inserting a spacer into the gap on the anti-dovetail engaging side to integrate the first and second members.

[0006]

As the base material and surface material of the present invention, long-sized extrusion molded products having a uniform cross section can be used.
It is suitable for mass production. According to the present invention, the contact surface between the base material and the surface material is provided with at least one dovetail-shaped concave line and convex line, respectively, and the width of the convex line is narrower than the width of the concave line.

Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1C shows a side view of the base material 1 of the embodiment, which is elongated in the depth direction of the drawing. A groove 11 having a dovetail shape 13 is formed on the surface of the base material 1 that is joined to the surface material 2. A convex shape 12 is formed between the two rows of concave lines 11. On the other hand, the surface material 2 is a ridge 21 that engages with the groove 11.
Is protruding. The ridge 21 has a width L ₂ narrower than the width L ₁ (see FIG. 1 (a)) of the groove 11. Again 2
Between the ridges 21 of the row, there is a ridge 22 corresponding to the ridge 12. The base material 1 and the surface material 2 are
Overlap, and as shown in FIG. 1A, the engaging portions 13 and 23
When the spacers 3 are engaged with each other and the spacer 3 is interposed in the gap on the side opposite to the engaging portion, the composite panel of the embodiment of the present invention is obtained.
At this time, an adhesive may be additionally applied between the base material 1 and the surface material 2 to combine them. This composite panel is the base material 1
Since the surface material 2 and the surface material 2 are firmly bonded by the engagement of the dovetail portions 13 and 23, and the spacer 3 holds this bonding, the base material 1 and the surface material 2 are tightly integrated.

The surface material 1 may be made of ceramic, stone, glass, ceramics, cement, metal, organic material or the like for decorating the surface of the composite panel. An inorganic material such as cement is mainly used as the base material 1, but the base material 1 is not particularly limited to this. Various materials can be used for the spacer 3 regardless of the material, the cross-sectional shape, and the length. The spacers 3 may be long ones from one end to the other end of the plate of the base material 1 and the surface material 2, but some short ones may be inserted. The spacer material is inorganic,
Metallic or organic materials can be used. An elastic material such as rubber is preferable in terms of work since it can be easily fixed. Inorganic materials (cement-based, etc.) have high durability. Metal is easy to insert. There are rod-like spacers such as spacers 31 having a trapezoidal cross section, spacers 32 having a rhombic cross section, and spacers 33 having a square cross section, as shown in FIGS. 2 to 4, depending on the shape of the gap. Further, as shown in FIG. 5, the vertical and horizontal dimensions may be changed, and a tightening force may be applied to the base material 1 and the surface material 2 by rotating 90 degrees. Further, as shown in FIG. 6, inclined short wedge-shaped pieces 35 and 36 are attached to the surface material 2 and the base material 1, the base material 1 and the surface material 2 are overlapped, and then the wedge-shaped pieces 35 and 36 are wedged. It can also be fixed by sliding it slightly in the direction in which the force acts. The wedge-shaped pieces 35 and 36 may be provided with inclined projections as the shapes of the base material and the surface material themselves at the time of manufacturing.

The shapes of the base material 1, the surface material 2 and the spacers 3 are such as shown in FIGS. 1 to 6 as long as the basic items of engagement of the dovetail portion and fixation by the spacers are satisfied. The same thing can be manufactured regardless of. The base material 1 shown in FIG. 1 was manufactured by extrusion molding with cement. Further, the surface material 2 shown in FIG. 1 was manufactured from a ceramic plate.
