Modular Cork Panels for Concrete Stairs

Finishing material for stairs that reduces slipping and impact using horizontal and vertical panels with replaceable cork cushioning inserts.

This technology is a modular stair panel system consisting of horizontal and vertical panels that cover the treads and risers of concrete stairs, respectively. The panels are joined at a right angle and feature removable cork cushioning inserts.

Conventional modular stairs involve cumbersome installation processes, such as complex tread assembly and the need for separate anti-slip measures to meet building codes. Wood treads are prone to rot from rain and snow, while concrete is heavy, making installation in high-altitude areas difficult and maintenance challenging.

This technology features a horizontal body with an internal insertion space containing an inclined plane and multiple fixing members to secure the cork cushioning. The vertical body accommodates a second cushioning member in the same manner, and the surfaces can be coated. The vertical panel's protrusion fits into the horizontal panel's groove for detachable assembly, with a curved connector reinforcing the edge. Suitable for concrete stairs in apartments and schools, outdoor stairs in parks and trails, and remodeling old stairs, the elastic cork reduces slipping, noise, and impact on knees, and allows for easy replacement of worn-out inserts.

Key Features:

• A horizontal panel with one side contacting the stairs and an interior space for a removable, cork-based first cushioning member.
• A vertical panel with one side contacting the stairs, an interior space for a removable, cork-based second cushioning member, and a design that joins perpendicularly to the horizontal panel.
• A horizontal body featuring a first insertion space with an internal inclined plane, a first bent portion at the other end, and multiple first fixing members on the inclined plane.
• A connector with a curved body that joins the adjacent outer surfaces of the vertical and horizontal panels, featuring first and second insertion members that fit into each panel.
