The support rods 3 are perpendicular to the flat steels 2, and the ends of the support rods 3 are welded to the inner wall of the installation frame 1. Support rods 3 are installed on the upper and lower sides of the flat steels 2 to improve the overall strength of the steel grating. The surfaces of the installation frame 1, flat steels 2 and support rods 3 are all galvanized to improve the overall strength of the steel grating.

[0024] Reference Figure 1 , the support rods 3 on the same side are arranged at equal intervals.

[0025] ReferenceFigure 1 and Figure 2 The number of support rods 3 on the upper and lower sides of the flat steel 2 is equal and coincides in the horizontal plane.

[0026] Referring to Figure 1 and Figure 2 The upper and lower sides of the flat steel 2 are provided with fixing grooves 21, and the support rods 3 are located in the fixing grooves 21.

[0027] Referring to Figure 1 and Figure 3 The opposite outer walls of the mounting frame 1 are provided with connecting holes 4, and the outer wall of the mounting frame 1 is provided with a connecting assembly 5 matched with the connecting holes 4. The connecting assembly 5 comprises a connecting rod 51, a connecting plate 52, a connecting ring 53 and a threaded cover 54. The mounting frame 1 is provided with rod holes 6 corresponding to the connecting holes 4, and the rod holes 6 and the connecting holes 4 are symmetrically arranged on the mounting frame 1. The connecting ring 53 is installed on the inner wall of the mounting frame 1, and the inner hole of the connecting ring 53 coincides with the rod hole 6. The outer wall of the connecting ring 53 is provided with external threads. The connecting rod 51 passes through the connecting ring 53 and the rod hole 6 and is in sliding connection with the mounting frame 1. The connecting plate 52 is fixedly installed at the end of the connecting rod 51 away from the mounting frame 1. The inner wall of the threaded cover 54 is provided with internal threads and is in threaded connection with the connecting ring 53. The connecting plate 52 is located in the threaded cover 54. Adjacent steel grating plates are spliced with each other, the connecting rod 51 of one steel grating plate is inserted into the connecting hole 4 of another steel grating plate, the threaded cover 54 is rotated, the connecting rod 51 is moved towards the connecting hole 4, and the adjacent steel grating plates are spliced with each other, thereby improving the stability of the steel grating plate laying.
