Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is intended to facilitate paving by making wood bricks used for paving sidewalks etc. into a block disk shape.

Timber-brick sidewalks have a soft sound to the feet, are less reflective from the summer sun, and have an insulating effect from cold air in the winter.They also help prevent desertification due to urban paving, as moisture flows into groundwater through the gaps between the timbers. Compared to concrete or asphalt pavement, the natural power of wood has many advantages, but the reason why it is not widely used is because the production of wood bricks is done by hand, making it difficult to create a uniform product. Currently, users, especially local governments, do not use it for economic reasons because it is expensive, and it takes a lot of time to pave and pave roads.

Therefore, this invention is intended to facilitate the production of wood bricks, create a uniform product, reduce the labor involved in paving, reduce the overall cost, increase usage, and contribute to creating a more livable city and environment.

The size of one conventional wood brick is 5 cm to 6 cm square and 12 cm to 15 cm in height.

They were laid out on the ground leveled with sand, etc., with gaps of about 1 cm between them, and asphalt was injected into the gaps to fix them and make roads, so 200 to 300 pieces were required per 1 square meter, which meant 2 pieces per 1 square meter. It took about 3 hours of work.

In this invention, an outer frame is made in the shape of a polyhedron such as a quadrangle or hexagon, or a board shape such as a circle or an ellipse with a side length of 25 cm to 30 cm, wooden pieces are placed, and the gaps are filled with asphalt, synthetic resin, cement, etc. By producing 10 pieces of a certain size and shape, it is possible to fill 10 to 20 pieces per square meter, so the work can be completed in 20 to 30 minutes. In addition, blocks can be manufactured in a factory or other place where equipment and machinery are available, making it easy to manufacture blocks with good dimensional accuracy. Moreover, even if the dimensions of the wood vary, as long as the block is made with good precision, there is no problem in the work, so the log can be used as is, so the diameter is 5 cm.
It becomes possible to use thinned wood with a small diameter of 10 cm. In addition, since the factory can be operated with simple machinery and equipment, it can be located in a mountain village where the raw materials are available, even if it is far from the paving work site, which will help prevent depopulation of the mountain village.

As explained above, this invention has the effect of reducing the overall cost because it is possible to easily manufacture a highly accurate product without processing individual pieces of wood with high precision by forming wood pieces into a block disk shape.
