Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to blocks used for construction materials, paving stones, curb stones, etc. (It is a concept that also includes).

BACKGROUND OF THE INVENTION Conventional blocks of this type are generally made of one type of material such as concrete or mortar. Therefore, the properties of concrete and mortar themselves become the properties of the block.

Problems to be Solved by the Invention For this reason, conventional blocks, for example, when used as construction materials, have problems in strength and corrosion resistance against salt damage, and concrete in particular has low tensile strength, so In some cases, it was necessary to reinforce the structure with reinforcing steel. For example, in the case of paving stones or curbstones, they are easily worn out and have poor durability, and in order to display traffic signs, etc., they must be handwritten with paint, making the work complicated. . Furthermore, a common drawback is a lack of decorativeness, and in the past, in order to compensate for this, it was necessary to apply appropriate painting or the like before use.

The object of the present invention is to provide a block that eliminates these drawbacks.

Means for Solving the Problems A plastic plate is provided, which is integrally formed by connecting a decorative board and an anchor part having a planar extension parallel to the decorative board by a rod-shaped connecting part, The block body is disposed so as to cover the surface of the block body, and the anchor portion is buried at a substantially central position in the thickness direction within the block body.

Function: The plastic plate, which also has a decorative function, protects the surface of the block, while the anchor and connecting parts reinforce the strength of the block.

Embodiments Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Fig. 1 is a perspective view of the entire block, Fig. 2 is a vertical sectional view of the entire block, and Fig. 3 is a bottom view of a plastic plate. It has a rectangular parallelepiped-shaped main body 2 made of a material that can be solidified, is easily available, and is preferably inexpensive. A plastic plate 3 is fixed to the main body 2 with an anchor portion 3a embedded therein. The plastic plate 3 is constructed by integrally connecting a decorative plate having a shape that can cover one side of the main body 2 and an anchor part 3a with a rod-shaped connecting part. The anchor portion 3a has a rectangular parallelepiped shape with a planar extension parallel to the decorative board, and extends approximately one third of the width direction of the main body 2, and approximately the entire length of the main body 2 in the longitudinal direction. It is located almost in the center of the direction.

Next, an example of a method for manufacturing the block 1 will be explained based on FIG. First, the plastic board 3 is formed by extruding the decorative board together with the anchor part 3a and the connecting part, and then placed in a mold 4 that matches the shape of the block to be manufactured. Next, concrete, mortar, asphalt, etc. in a fluid state selected according to the purpose of use are placed in the mold 4.
After pouring into the mold and solidifying it, the block 1 is removed from the mold 4 to complete the block 1 as shown in FIGS. 1 and 2.

In addition, when manufacturing the above-mentioned plastic plate 3, it is possible to add a color pattern, and it is also possible to mix a light reflecting material or a fluorescent paint. In this way, adding color patterns to the plastic board 3 not only improves its decorative function, but also enables semi-permanent display of traffic signs, etc. Also, by adding light-reflecting material or fluorescent paint, it can be used at night. Since it facilitates visual recognition and improves its function as a sign, it is particularly suitable for use as a display on paving stones, curbstones, or traffic signs such as crosswalks.

Next, another embodiment of the anchor portion according to the present invention will be described based on FIGS. 5 and 6.

The anchor portion 5a of the plastic plate 5 in FIG. 5 has a rectangular parallelepiped shape extending in all directions from approximately the center of the plastic plate 5, and the anchor portion 5a and the decorative plate are connected by a single rod-shaped connecting portion. In addition, there are four anchor parts 6a of the plastic board 6 in FIG. 6, and a rectangular parallelepiped-shaped anchor part 6a is connected to each part of the decorative board of the plastic board 6 by a connecting part. It is.

Note that the present invention is not limited to the above-mentioned embodiments, and for example, anchor portions 3a, 5a,
The shape of 6a may be circular or elliptical in plan view, or protrusions or the like may be formed at appropriate locations. Furthermore, the shape of the block 1 is not limited to a rectangular parallelepiped, and can be changed in various ways. In addition, its size may be determined as appropriate depending on the application and the like, and is not limited in any way. Furthermore, the type of plastic can be used regardless of whether it is hard or soft, so it can be selected and determined as appropriate depending on the purpose, etc. Also, the decorative board can be installed only on one surface of the main body. It is also possible to provide on multiple surfaces.

Effects As is clear from the above explanation, according to the present invention, since the plastic plate with the anchor part embedded in the surface of the block is fixed, the plastic plate and the block body have mutually complementary functions due to the different materials. This not only makes it possible to reduce the weight of the block, but also protects the plastic plate fixing surface and improves its durability, allowing it to withstand long-term use.It also allows for the addition of colors and patterns, making it useful as a decorative material. Furthermore, the decorative board, the anchor part and the connecting part reinforce the block body almost entirely, increasing its strength, especially against tension. In addition, since the anchor portion has a planar extension parallel to the decorative board, the plastic board and the block body are firmly connected. In addition, the plastic body has many advantages such as ease of manufacture since the decorative plate, the anchor part and the connecting part can be integrally molded.
