KR970011181A - Sidewalk Blocks and Combination Methods - Google Patents

Abstract

1. Field of invention

The present invention relates to a sidewalk block attached to a sidewalk and a method of joining a sidewalk block consisting of an upper block and a lower block.

2. Technical problem to be solved by the invention

It is to provide a sidewalk block that combines the sidewalk block with the top block and the bottom block to improve impact resistance and sense of response by utilizing waste resources.

3. Summary of Solution to Invention

The sidewalk block of the present invention has an upper block formed with projections running in all directions on the surface of a substrate having a square shape, and a joining groove is formed at a cross section of one side of the joining side of the substrate having a square shape, and a cross section at the opposite side thereof is provided. When the coupling protrusions are formed to face the one side and the other side, the coupling groove and the coupling protrusion become lower blocks, and the rear surface of the upper block and the surface of the lower block are combined. In addition, the method of joining the side block of the upper block and the lower block of the present invention, by forming a plurality of coupling holes of the upper and lower straits in the upper block, the surface of the upper block is placed on the lower mold having a corresponding bottom shape Put the heated waste synthetic resin on the upper block and press the heated waste synthetic resin into the upper mold having the backside of the desired lower block so that the waste resin penetrates and cools the joining hole to the upper block and the lower block. To combine.

4. Important uses of the invention

Used to manufacture sidewalk blocks

Claims (4)

Coupling grooves 22 are formed in the upper block 1 on which the projections 12 are formed on the surface of the substrate 11 to form a rectangle, and on one end side of the bonding side of the substrate 21 to form a rectangle. Forming and forming a coupling protrusion 23 on the opposite side of the opposite side to form a lower block (2) for coupling the coupling groove 22 and the coupling protrusion 23 when the seven side and the other side is abutted, Sidewalk block, characterized in that by coupling the back surface of the upper block and the surface of the lower block (2). The sidewalk block according to claim 1, wherein the lower block (2) is formed with a stiffening plate (24) for preventing flow on the rear surface of the substrate (21). 3. The sidewalk block according to claim 1 or 2, wherein the upper block (1) is formed by regenerating a pet tire and the lower block (2) is formed by regenerating waste synthetic resin. The method of claim 3, wherein the method of combining the upper block and the lower block comprises: forming a plurality of coupling holes of the upper and lower narrow beams and placing the upper block on a lower mold having a corresponding bottom shape, and then the upper block. Put the heated waste synthetic resin on top and press the heated waste synthetic resin into the upper mold having the backside of the desired lower block to allow the waste resin to penetrate and cool the joining hole, thereby joining the upper block and the lower block. Method of coupling the sidewalk block, characterized in that. ※ Note: The disclosure is based on the initial application.
