Description

[Detailed description of the invention] The present invention relates to a wooden block for sidewalks that allows the growth rings of the wood to be clearly seen.

Conventionally, sidewalk blocks made of concrete were hard and tiring for pedestrians. Due to poor water permeability during rainfall, water puddles were likely to form. On a midsummer day, the sunlight returned was hot. Due to their weight, it was not possible to take up a large construction area per piece, resulting in poor construction efficiency. It was difficult to cut the edges of the construction surface. It is an object of the present invention to eliminate the above-mentioned drawbacks.

Its composition is as follows. It consists of a large number of cylindrical trees with annual rings 1 that are machined into a perfect circle so that the annual rings of the wood spread from the center toward the outer edge, and then cut into short rings. are connected and fixed in a wooden frame 2 so that the upper and lower surfaces are the upper and lower sides, and horizontal beams 3 are placed at intervals on the back of the wooden frame 2, and the middle part of the wooden frame 2 has a circular shape. It is a wooden block that incorporates a cylindrical tree with annual rings cut vertically in the center and placed together. This wooden block is coated with a preservative.

Its usage is as follows. I use a lot of these wooden blocks. There is a cut part in the middle, so if one piece at the end is unnecessary, use that cut part to cut it in half. Fill the gap between the cylinders with sand.

The effects are as follows. Since it is molded only from natural wood, it has a rustic, natural feel and gives a sense of peace. It has a suitable amount of elasticity, so it feels good when walking and you don't feel tired. Because the gap between the cylinders can be filled with sand, water permeability is very good. Due to its light weight, the construction area of each block is more than double that of conventional products.
Construction efficiency will be doubled. It has a cutting part built into the middle, so it can be easily divided into halves. Many changing annual rings appear on the surface, adding to its beauty.
