Description

Double structure floor tile and floor tile construction method using the same

The present invention relates to a floor tile having a double structure and a floor tile construction method using the same.

In general, the entrances and passages of warehouses in factories are finished with concrete or epoxy paint. In industrial sites such as factories or logistics warehouses, where the movement of forklifts and freight vehicles, and mechanical facilities such as press devices or punching devices, generate severe impact, cracks frequently occur in the concrete or epoxy floors, and maintenance work is performed repeatedly. There is a difficult problem.

In the case of an epoxy floor, it is difficult to operate equipment such as a forklift due to damage or cracks (cracks) of the epoxy floor, as well as inconvenience in walking and moving products (loading pallets, etc.). In addition, there are problems such as a curing period for curing cracks, generation of steps due to cracks or damage, and generation of dust.

As such, in the case of concrete or epoxy floors, frequent breakage and repairs caused inconvenience, so a floor check plate (iron plate) floor was constructed as an alternative method. There are problems such as warping or detachment of welded parts, and lifting with the floor due to detachment, or stepping caused by lifting. In addition, walking is inconvenient due to the occurrence of a step, and there is inconvenience in that dust is blown every time you walk, and there is an inconvenience even when operating the equipment.

In addition, in the case of an iron plate floor, a long-term construction period is required by connecting ready-made iron plates of a certain size by welding. there is

As such, in the floor used in the industrial field, the epoxy or iron plate finish has a problem in that it is vulnerable to compressive strength, flexural strength (large iron plate), cracks (cracks), and moisture.

6 is a view showing that two floor tiles 1 having a double structure according to an embodiment of the present invention are connected, and FIG. 7 is a view showing that two floor tiles 1 having a double structure according to an embodiment of the present invention are connected. It is a plan view showing a state, and FIG. 8 is a view showing that a plurality of floor tiles 1 having a double structure according to an embodiment of the present invention are installed.

A method in which a plurality of double-structured floor tiles 1 are constructed will be described with reference to FIGS. 6 to 8 .

For example, the double-structured floor tile 1 may be installed and positioned on the ground in a state in which the metal tile 10 and the assembly panel 20 are fastened and assembled by the fastening member 30 . That is, the metal tile 10 and the assembling panel 20 may be fastened and constructed while the floor tile 1 having a double structure is disposed at a position to be constructed.

Alternatively, in a state in which the assembly panel 20 is not fastened with the metal tile 10, the assembly panel 20 is first positioned at the place to be constructed, and the metal tile 10 is placed on the assembly panel 20. After that, the fastening member 30 can be inserted into the fastening hole 11 and the fastening hole 22 for construction.

As such, the metal tile 10 and the assembly panel 20 may be constructed in an assembled state, or may be assembled after construction in a state before assembly.

As described above, in the double structure floor tile 1 , the metal tile 10 and the assembly panel 20 form a pair to form a double structure.

When two pairs of the pair of metal tiles 10 and the assembly panel 20 are connected, a third assembly groove between the third assembly projections 233 disposed below the pair of metal tiles 10 (243) or in the fourth assembly groove 244 between the fourth assembly projections 234, the first assembly projection 231 or the second assembly protruding outside the rim of the other pair of metal tiles 10 A protrusion 232 may be inserted. As such, when the two pairs are connected, the assembly panel 20 of the portion connected by the metal tile 10 may be shielded.

Specifically, as shown in FIG. 6 , the method for fastening the floor tile 1a of the first double structure on the right side and the floor tile 1a of the first double structure on the left side is the method of fastening the floor tile 1a of the first double structure ( The fourth assembly protrusion 234a of 1a) is inserted and fastened between the second assembly grooves 242b of the second double structure floor tile 1b, and the fourth assembly of the first double structure floor tile 1a A second assembly protrusion 232b of the floor tile 1b having a second double structure may be inserted and fastened between the grooves 244a. The second assembly protrusion 232b of the floor tile 1b of the second double structure protruding to the outside by fastening the floor tile 1a of the first double structure and the floor tile 1b of the second double structure, As shown in FIG. 7 , it may be shielded by the metal tile 10 of the first double-structured floor tile 1a positioned on the upper side.

As shown in FIG. 8 , it is possible to arrange and assemble a plurality of floor tiles 1 having a double structure according to a construction site. As an example, the second double structure floor tile 1b on the left side of the first double structure floor tile 1a is fastened and assembled in the same manner as described above in FIGS. 6 and 7 , and similarly, the first double structure floor tile 1b The third double structure floor tile 1c is fastened to the right side of the floor tile 1a, and the fourth double structure floor tile 1d is fastened and assembled to the front of the first double structure floor tile 1a, , it is possible to fasten the floor tile 1e of the fifth dual structure to the front of the floor tile 1a of the first dual structure.

In this way, by fastening and assembling a plurality of double-structured floor tiles in the left and right front and rear directions, it can be installed according to the area of the construction site.

9A is a bottom perspective view of a metal tile 10 having an insertion hole 13 formed therein according to an embodiment of the present invention, and FIG. 9B is a cross-sectional view taken along line A of FIG. 9A .
