It is installed as a prefabricated structure, so that the viewer can express the wood texture effect. Especially, when it is installed on the exterior wall of the building, it is used as exterior finishing material that can reinforce the waterproof and durability.

In the traditional form mainly using wooden boards, in recent years, siding is made of materials such as polyvinyl chloride (PVC), steel (steel) in consideration of the natural damage caused by the production of wood.

As described above, in the siding having less shape deformation and higher durability, the first priority of the present invention relates to the vertical connection of the siding. The siding is basically assembled with a plurality of panels overlapping partly in the vertical direction or the left and right direction, in which the individual siding is fastened to the outer wall and the like, and at the same time the fastened part is covered by another siding from the outside It is made of a protected structure.

1 and 2 are respectively a perspective view showing an example of a conventional siding 10 and a side cross-sectional view showing a state in which the siding 10 is fastened. A siding will be described with reference to FIGS. 1 and 2.

The siding 10 of FIG. 1 relates to vinyl siding and has a panel 20, a fastening rib 30 formed at an upper end of the panel, and a coupling rib 40 formed at a lower end thereof. The fastening rib 30 has a long hole 32 formed so that the siding is fastened to the outer wall A by a fastening member S such as a bolt, and the fastening rib 30 is appropriately bent to the side cross-section thereof. In the locking jaw 34 having a "∪" shape is formed. In addition, the coupling rib 40 is also formed with a "jaw" shaped locking jaw 44 corresponding to the locking jaw 34 of the locking rib, wherein the locking jaw 44 of the coupling rib Size is adjusted so that the locking step 34 of the rib can be fitted.
