Abstract

The present invention is to provide a prefabricated sidewalk block effective for maintaining the flatness of the construction and the construction state by the mutually matched coupling between the male and female, in the square or rectangular sidewalk block (1), the coupling grooves on the two sides met at a right angle (6a, b) is formed, and the other two sides are formed with the engaging projection (7a, b) corresponding to the coupling groove (6a, b).

And the coupling groove (6a, b) and the coupling projections (7a, b) to the top and bottom of the male and female coupling is to smoothly and to strengthen the coupling state.

Description

Prefabricated Walkway Blocks {A buit-up type foot way block}

The present invention relates to a prefabricated sidewalk block effective for maintaining the flatness of the construction and the construction convenience by mutually matched coupling between male and female.

A typical square, long walkway block is flat on all sides. When the sidewalks are constructed with these sidewalk blocks, they are not properly fitted, and some of them are low and some are high, which leads to poor construction conditions.In particular, after laying gas, water, sewage, and storm pipes underground, In case of backfilling and reconstruction of the sidewalk block, there is a high possibility of uneven settlement because the strength of foundation ground is not uniform. At this time, the partial protrusion of the sidewalk block is prominent, making it difficult to walk safely and causing pedestrian safety accidents.

Accordingly, an object of the present invention is to provide a prefabricated walkway block that can be constructed as a walkway with excellent flatness by strengthening the binding force between adjacent walkway blocks, and the construction state can be maintained flat. The adjacent sidewalk blocks are formed by forming the defect grooves into which the engaging projections of the pre-installed sidewalk blocks are fitted on two sides of the four sides of the magnetic barrier block, and the engaging projections covered by the defect grooves of the other sidewalk blocks to be post-installed on the other two sides. It provides a prefabricated walkway block that can be built into a more stable sidewalk and maintains the construction state of the walkway by mutual male and female fit.

1: Press block 6a, b: Coupling groove 7a, b: Coupling protrusion

In Fig. 1 and Fig. 2, the sidewalk block 1 is in principle made of a square or rectangular plane. In the sidewalk block 1 having such a shape, the coupling grooves 6a and b are formed on the two side surfaces 2 and 3 which are met at right angles among the four sides, and the defect grooves 6a and 2 are formed on the other two sides 4 and 5. b) engaging protrusions 7a and b corresponding to the above are formed. The defect grooves 6a and b and the engaging protrusions 7a and b are formed in the middle of the thickness of the sidewalk block 1 so that the other sidewalks are connected in either direction. The mutual engagement with the block is made easy. To facilitate the engagement between the coupling grooves 6a and b and the coupling protrusions 7a and b, as illustrated in FIG. A gradient is placed above and below each of b) and engaging projections 7a and b. In Figs. 4 and 5, after adjusting the ground of the sidewalk, the sidewalk block 1 is laid in the lattice direction. At this time, the sidewalk block 1 is laid on the back side of the road boundary stone 8, that is, the sidewalk side, as in the case of constructing any sidewalk block. The same applies to laying the sidewalk block 1 in a diagonal direction. When the fitting groove 6a or 6b is fitted to the road boundary stone 8, the engaging protrusion 7a or ( 7b) and fit the engaging groove (6a) or (6b) of the sidewalk blocks (1a, b, ...) to be constructed later, and fit the engaging projection (7a) or (7b) to the road boundary stone (8) When constructing, fitting the engaging projections 7a or 7b of the sidewalk blocks 1a, b, ... to be constructed later into the engaging grooves 6a or 6b of the previously constructed sidewalk block 1 In any case, the interlocking between the coupling grooves 6a and b and the engagement protrusions 7a and b increases the coupling force between the sidewalk blocks 1 so that all sides are intact. The coupling grooves 6a and b and the engaging projections 7a and b are easy to grip so that the fingers can be moved when carrying multiple sidewalk blocks 1 at the same time using both arms. Uh easy carrying.

As described above, the sidewalk block of the present invention forms a joining protrusion fitted to the joining grooves on two sides of the four sides and the joining grooves on the other two sides, and has a strong binding force between the sidewalk blocks that are continuously joined to each other. It is excellent in stress, and safe walking is possible.

In addition, the fitting grooves and the engaging projections are fitted to adjust the seam flat, so the construction is excellent, and the construction state is long lasting durability of the sidewalk is also long, so the maintenance cost reduction effect is also great.

In addition, the coupling groove and the engaging projection is convenient to carry to the site as well as construction.
