The present invention relates to an apparatus to fixate a safety net for a bridge capable of being easily installed to a lower structure of a pre-stressed concrete (PC) beam comprising: an inclined bar being in contact with a lower inclined surface of an outer side of a PC beam; a first vertical bar connected to the inclined bar, and being in contact with a vertical surface of the outer side of the PC beam; a horizontal bar connected to the first vertical bar and being in contact with a lower side surface of the PC beam; a second vertical bar connected to the horizontal bar, and extended along a lower vertical surface of an inner side of the PC beam; a pressurization unit coupled with the second vertical bar to control a fixation strength with respect to the PC beam by controlling a pressure pressurized to the vertical surface of the lower vertical surface of an inner side of the PC beam; at least one unit to fixate a safety net connected to the first vertical bar and horizontal bar; and a bar to fixate a safety net upwardly extended to the outside of the outer side of the PC beam. |
