PURPOSE: A non-slip structure for stairs is provided to simply remove foreign materials from a non-slip when the non-slip is slid frontward. CONSTITUTION: A non-slip structure for construction stairs is comprised as follows. A dust receiver(30) is installed in the corner portion of each stair(20) to be buried in the corner portion. Semicircular grooves are formed on the bottom surface of the dust receiver. Dust inlet holes(41) are formed in each non-slip(40). The non-slip is inserted into the top(31) of the dust receiver and a front fixing protrusion. Sliding ribs are formed on the side surfaces of the non-slip and are coupled to guide grooves formed on the side walls(32,34) of the dust receiver. A rubber scrapper is installed in a T-groove formed on the bottom surface of the non-slip. A position fixing protrusion is formed on the rear end of the non-slip and is coupled to a position fixing hole(38) formed on the rear wall of the dust receiver. |
