Description

[Detailed explanation of the invention] This invention relates to a decorative board suitable for being directly attached to a concrete floor surface, and provides an inexpensive decorative board that can be applied by adapting to the unevenness of the concrete floor surface. The purpose is to

That is, in this invention, a plurality of rectangular decorative materials are connected in the longitudinal direction to form a long decorative material, and a plurality of these long decorative materials are sequentially shifted laterally in the transverse direction. A wide decorative material is formed in a row, and a flexible base material having approximately the same shape as the wide decorative material is attached to the back side of the wide decorative material.
Each rectangular decorative material is a decorative board that is not fixed to each other.

A detailed description will be given below with reference to the drawings of the embodiments.

Reference numeral 3 is a rectangular decorative material, which is made of a plate material such as plywood, particle board, hardboard, etc., with a suitable decoration applied to the surface. Decoration refers to things constructed by pasting veneer or decorative sheets, painting, or pattern printing, for example. A transparent paint layer mixed with alumina or silicon carbide may be formed on the surface of the above-mentioned makeup in order to improve wear resistance. A plurality of rectangular decorative materials 3 are connected in the longitudinal direction to form a long decorative material, and a plurality of the long decorative materials are connected in the lateral direction in a manner that is sequentially shifted laterally. A wide veneer (as shown in Figure 1) is formed. At this time, the seams of the rectangular decorative material 3 are made to be staggered.

In addition, the manufacturing order may be such that the rectangular decorative materials 3 are arranged in a row in the longitudinal direction or in the lateral direction. Of course, you can do both at the same time. The most suitable means for joining them is to use adhesive tape on the back side of the decorative material 3, but they may also be joined by hot melt. A flexible base material 6 having substantially the same shape is attached to the back side of the wide decorative material thus formed. As the flexible base material 6, natural rubber, synthetic rubber,
Vinyl chloride resin is generally considered, and includes those mixed with inorganic powders and fibers.

Fig. 1 is an embodiment of this invention, and Fig. 2 is an enlarged plan view of the rectangular decorative material 3 used in the embodiment of Fig. 1. Male seeds 4 and female seeds 5 are formed on the facing sides, respectively. The male fruit 4 is thinner than the female fruit 5, and when the adjacent rectangular decorative material 3 is fitted, there is a large gap between the male fruit 4 and the female fruit 5, as shown in Figure 3. The rectangular decorative materials 3 can move freely in the fitted state. 6 is a flexible base material.

This idea is structured as described above, so
It can be applied to uneven concrete surfaces without any problems, and since multiple long decorative materials are successively shifted laterally in the width direction,
This method has the advantage that joining the decorative boards is very simple, and after joining, the joints of the long decorative materials become staggered, making it possible to construct a floor surface with a very beautiful appearance. In addition, as shown in Fig. 3, the male fruit 4 and female fruit 5 are fitted with a large gap between them, and the rectangular decorative materials can move freely in the fitted state. Since the male seeds 4 are in contact with the female seeds 5, the wide decorative materials are not bent in the lateral direction more than necessary, and the wide decorative materials can be easily handled.
