PURPOSE: A grating having a high load support structure and an anti-slip structure is provided to efficiently drain water when heavy vehicles pass through the grating and prevent safety accidents by maximizing the supporting force of the grating. CONSTITUTION: A grating (100) having a high load support structure and an anti-slip structure comprises end bars (110), multiple patterned steel plates (120), bearing bars (130), and cross bars (140). The end bars form the rectangular edge of the grating. The patterned steel plates are installed on the inner side of the end bars, and patterns (122) are formed on the surfaces thereof. One or more reinforcement bars (126) are fixed to the bottoms of the patterned steel plates. The bearing bars are installed between the patterned steel plates at uniform intervals, and coupling grooves (132) are formed on the top surfaces thereof. The cross bars are coupled to the coupling grooves of the bearing bars. |
