The present invention relates to a prefabricated drain box grating, and more particularly, the grid structure of the drain box grating, which is used as a lid of a drainage road, such as a road or a river, is formed in an approximately "# " They are formed to protrude outwards, so that the outer edge of the lattice spherical body itself is eliminated, and soil or stones are tightly inserted along the edges, so that the drain box grating itself does not fall out of the drain box or prevent breakage. In addition, the present invention relates to an assembled drain box grating capable of preventing theft.

In general, a water collecting well or a drainage pipe is installed around a road or a river to drain and drain rainwater, and a metal drain box grating is installed in the form of a lattice structure.

Most of the drain box is to place the concrete in the field construction or to use the drain box made in the factory as a drain.

To explain this in more detail, most of the rectangular drain box grating (grating) made of steel (STEEL) on the L-shaped step on the top is installed in a grid form is used as a lid.

However, in the conventional drain box grating structure as described above, a rectangular outer edge is surrounded at the edge of the lattice structure, and thus, in the outermost space portion along the lattice structure edge of the rectangular grating, for a long time, In addition, when the stones are tightly fitted, the drain box grating itself does not fall out of the L-type step when working for maintenance or the like, or there is a problem that is broken by a strong force.

In addition, the conventional drain box grating structure as described above does not have a separate anti-theft device, there is a loophole that expensive drain box grating can be easily stolen.

The present inventors have made great efforts to solve the conventional problems as described above and have completed the present invention.

Accordingly, an object of the present invention is to form a grid structure of the drain box grating used as a lid of a drainage passage, such as a road or a river, so that the ends of each horizontal and vertical bar member protrude outwards in an approximately "#" form. The outer periphery of the grid spherical body itself is eliminated so that the soil or stones are tightly fitted along the edges to provide a prefabricated drain box grating to prevent the drain box grating itself from falling out or breaking.

Another object of the present invention is to provide a prefabricated drain box grating in which the prefabricated drain box grating is fixedly installed through a chain locking means, thereby preventing theft of the drain box grating.

Each of the first fitting grooves and the second fitting grooves of each of the plurality of vertical rod members are fitted to each other to form a lattice structure that is arranged at regular equidistant intervals in rows and columns in a matrix form. It is characterized by.

In this case, the lattice structure is formed in the form of "# " in which the ends of each of the horizontal and vertical bar members protrude in all directions.

In addition, the lattice structure is preferably in the form of a 4 × 4 matrix.

In addition, a locking means passage hole is formed in the horizontal or vertical bar member positioned at the outermost part, and one end of the locking means is disposed in the horizontal or vertical bar member adjacent to the outermost horizontal or vertical bar member in which the locking means passage hole is formed. Preferably welded and fixed, the other end of the locking means exits through the locking means passage hole and is fixed to the outside of the drain box.

In addition, when the rectangular drain box extends horizontally or vertically, a plurality of lattice structures in which the ends of the horizontal and vertical bar members protrude outwardly in the form of "#" form a plurality of horizontally or vertically. It is preferable to be mutually welded to the adjacent lattice structure by attaching a separate bar member on the side of the end of the protruding horizontal or vertical bar member.

As described above, according to the new concept assembled drainage box grating according to the present invention, the grid structure of the drainage box grating used as a lid of a drainage passage, such as a road or a river, is approximately "#" in the form of each horizontal and vertical bar. By forming the end portions of the members to protrude outwards, the outer edge of the lattice spherical body itself disappears, and soil or stones are fitted tightly along the edges, so that the drain box grating itself, which is a conventional problem, does not fall out or breaks. The source can be prevented and is completely fixed by a separate chain-shaped locking means, thereby preventing the source of the drain box grating from being sourced.
