Abstract
The invention relates to a bridge trapezoid section bar which is made of board bodies. The trapezoid section bar comprises an upward bent edge and a downward bent edge. The upward bent edge is bent to an m-shaped double-layer hook edge, the downward bent edge is bent to an E-shaped bent edge, and the bent edges are filled with reinforcing ribs. The bridge trapezoid section bar is simple in structure and convenient to machine, the upward bent edge is bent to the m-shaped double-layer hook edge, the downward bent edge is bent to the E-shaped bent edge, the bent edges are filled with the reinforcing ribs, and therefore the strength and the carrying capacity of the trapezoid edges are improved.
Description
Technical field
The present invention relates to a kind of crane span structure, be specifically related to a kind of crane span structure trapezoidal profiles.
Background technology
Cable testing bridge is in capital construction project, for standard, to protect the capital equipment of the safety of cable and transmission line.Extensive in sector applications such as oil, chemical industry, electric power, light industry, telecommunications, the cross section of traditional bridge ladder limit section bar mostly is
shape, this structural strength is low, and bearing capacity ratio is poor.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of simple in structure, easy to process, the terraced limit section bar of the crane span structure that intensity is high.
A trapezoidal profiles, described terraced limit section bar is processed by plate body, and described trapezoidal profiles comprises upper hem and lower hem, and described upper hem is converted into the double-deck crochet of m shape, and lower hem is converted into E shape flanging, the inner reinforcement of filling of described flanging.
Beneficial effect:
The present invention is simple in structure, easy to process, and upper hem is converted into the double-deck crochet of m shape, and lower hem is converted into E shape flanging, and the inner reinforcement of filling of flanging, has improved intensity and the bearing capacity on terraced limit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
A kind of crane span structure trapezoidal profiles, described terraced limit section bar is processed by plate body 1, described plate body 1 can be by corrosion resistant plate or magnesium-aluminum alloy plate etc., described trapezoidal profiles comprises upper hem 2 and lower hem 3, described upper hem 2 is converted into the double-deck crochet of m shape, lower hem 3 is converted into E shape flanging, in order further to improve the intensity of crane span structure, also at the inner reinforcement 4 of filling of flanging.
The present invention is simple in structure, easy to process, and upper hem 2 is converted into the double-deck crochet of m shape, and lower hem 3 is converted into E shape flanging, and the inner reinforcement 4 of filling of flanging, has improved intensity and the bearing capacity on terraced limit.
Description of the invention and application are illustrative, not want that therefore, the present invention is not subject to the restriction of the present embodiment by scope restriction of the present invention in the above-described embodiments, and the technical scheme that any employing equivalence replacement obtains is all in the scope of protection of the invention.
Claims (2)
