AI Technical Summary
When welding square tubes to existing trench covers, the weld points are exposed on the front of the cover, affecting the surface flatness and appearance, and the connection strength is insufficient.
A new type of square tube welding structure is adopted. Long and short slots are opened on the cover plate, and clamps bent inward at 90 degrees are set at their intersections. The clamps are welded to the square tube to form a clamping space to accommodate the square tube. The weld points are hidden under the clamps. The clamp-type connection replaces the point seam connection to enhance the tightness.
It maintains the flatness and aesthetics of the cover plate surface, while significantly improving the tightness and stability of the connection.

TECHNICAL FIELD
[0001] The utility model relates to road facility technical field more specifically, it relates to a stainless steel ditch cover plate. BACKGROUND
[0002] The ditch cover plate is a device commonly used in urban infrastructure construction, mainly used for covering and protecting underground ditches, drainage systems, cable trenches, etc., with bearing and protection functions. When designing the ditch cover plate, it is necessary to prevent foreign matter from falling into the underground ditch to ensure the safety of underground facilities, and to have bearing capacity to ensure the safety of vehicles or pedestrians passing through.
[0003] Welding square tubes on the ditch cover plate can increase the difficulty of cover plate bending deformation through partition, thereby improving the support strength of the cover plate. Welding square tubes on the ditch cover plate is an effective method to enhance the structure, improve the bearing capacity and stability, and is widely used in areas with frequent traffic or heavy load. However, in the existing ditch cover plate, the square tube is directly welded on the panel of the cover plate, which makes the welding points obvious on the front surface of the cover plate, affecting the flatness of the cover plate surface and being very unattractive.

[0006] As a further scheme of the utility model: the long strip leak groove and the short strip leak groove are staggered and arranged, and present a dense pattern on the board body.
[0007] As a further scheme of the utility model: the end of long strip leak groove and short strip leak groove is gathered to the center and presents a convex point shape.
[0008] As a further scheme of the utility model: one square tube is welded with four clamping pieces, and the connecting point of the clamping piece and the square tube is located at the corner of the square tube.
[0009] As a further scheme of the utility model: the vertical section of the board body presents an inverted U shape, and the side edge of the board body and the end of the square tube are provided with a gap.
[0010] As a further scheme of the present application, the plate body is vertically upward, the plate body longitudinal depth is greater than the square tube, and the square tube longitudinal depth is greater than the clamping piece.
[0011] The present application has the advantages that:
