PURPOSE: A stairway nonslip structure for a building is provided to facilitate to remove foreign substances in between nonslip bars by separating the nonslip bars from a stairway for freely bending and lengthening. CONSTITUTION: A stairway nonslip structure for a building comprises a nonslip bar (20), a rubber joint plate (30), a wedge (40), a lower plate (50), a nonslip fixed box (60), an insert block (70), and a home insert (80). The upper surface of the rubber joint plate is formed with a bar fixing groove for inserting the lower part of the nonslip bar. The wedge is joined to a taper hole formed in the lower side of the nonslip bar. The lower side of the nonslip fixed box is formed with a dovetail rib (61). The lower and upper sides of the lower plate are separately formed with a square rib (52) and a square groove (62) to be connected to each other. An insertion block is fixed to a tap hole (64) formed in the nonslip fixed box through a fixing bolt (76). The home insert is installed in the T-groove of the nonslip bar. |
