Further improve:
Described the second stiffening rib is along the length direction setting of terraced thick stick body, and the cross section of described the second stiffening rib is trapezoidal or semicircular arc.
Further improve:
Be provided with transition part between described terraced thick stick body and side plate.
Further improve:
Described terraced thick stick is located at the bottom of side plate, and the end away from terraced thick stick on described side plate is connected with curved part.
Further improve:
The trapezoidal bridge frame cover plate that a kind of and above-mentioned trapezoidal bridge frame matches comprises plate shaped cover board body, is provided with two article of the 3rd stiffening rib along the length direction of cover board body, and every the 3rd stiffening rib is located near the cover board body outer edge.
Further improve:
Length direction along cover board body is provided with several projections, and described projection is located at two article of the 3rd position between stiffening rib.
Further improve:
The two ends of described cover board body are respectively equipped with the engagement portion.
The utility model adopts technique scheme, and is with low cost, easy to process, simple in structure, intensity is high, and easy for installation; Side plate and terraced thick stick adopt the integrated punching bending and molding, have effectively reduced difficulty of construction, make connection more firm; The setting of the second stiffening rib can effectively increase the intensity of terraced thick stick body; The setting of curved part can prevent from scratching cable when installing cables; Cover board body is provided with the 3rd stiffening rib and the protruding intensity that can effectively guarantee cover plate, has avoided the cover plate distortion.
Below in conjunction with accompanying drawing, the technical solution of the utility model is described further.
