The utility model adopts the monoblock plate stamping to process, and need not welding, the environmental pollution of having avoided welding procedure to cause; Improved the antiseptic power of product, reduced welding, the stiffening rib that the middle part is flute profile has been set on cross-arm simultaneously crane span structure sheet material stress influence; Improved the integrated carrying ability of crane span structure; The two ends Y shape bifurcated of flute profile stiffening rib has not only increased the surface of contact on cross-arm and terraced limit, has disperseed stressed surface of contact, and has improved the bearing strength of cross-arm; Need be through just not satisfying the requirement of carrying cable under the situation that increases crane span structure section bar thickness, satisfied the needs in the strong environment of humidity and corrosivity fully.Especially in ocean environment, show more obviously.
The bottom on said terraced limit is L shaped structure, and forms stiffening rib.
The stiffening rib of the L shaped structure of ladder limit bottom can limited raising crane span structure bulk strength.
The top on described two terraced limits is provided with inverted U-shaped.
Inverted U-shaped on the ladder limit can improve the intensity on terraced limit on the one hand, can avoid scratching the cable that is laid on the crane span structure on the other hand.
The root outer rim at described flute profile stiffening rib middle part is provided with the reverse reinforced block of at least one pair of along the cross-arm longitudinal direction.
Reverse reinforced block is equivalent to increase reverse stiffening rib in the root both sides at flute profile stiffening rib middle part, improves the stability and the bearing strength of crane span structure.
Described terraced limit is provided with some radiation holes, and this radiation hole vertically is provided with along terraced limit.
The deadweight of fixing and reduce crane span structure when radiation hole is used for the crane span structure installation.

Embodiment
Below in conjunction with accompanying drawing the technological scheme of the utility model is done detailed explanation.
Embodiment one:
Like Fig. 1-shown in Figure 5, the integrated type ladder-type cable bridge of the utility model comprises two terraced limits 1 and cross-arm 2, and process for the monoblock plate stamping with cross-arm 2 on this ladder limit 1, and sheet material can adopt carbon steel, stainless steel, aluminum alloy or the like can satisfy the sheet material of requirement of strength.Cross-arm 2 is provided with flute profile stiffening rib 3, and when the Y-shaped bifurcated in the two ends of this flute profile stiffening rib 3, stressed more even, intensity is higher; Cross section is trapezoidal in the flute profile stiffening rib 3, and the end face of this flute profile stiffening rib or bottom surface are provided with some horizontal long-round-shape mounting holes 4.The protrusion direction of flute profile stiffening rib 3 can form the convex stiffening rib up, and at this moment, the long-round-shape mounting hole site also can form the spill stiffening rib down on the end face of flute profile stiffening rib, and long-round-shape mounting hole 4 is positioned on the bottom surface of flute profile stiffening rib at this moment.
The integrated type ladder-type cable bridge of the utility model adopts the monoblock plate stamping to process, and need not welding, the environmental pollution of having avoided welding procedure to cause; Improved the antiseptic power of product; Reduce welding to crane span structure sheet material stress influence, the stiffening rib that the middle part is flute profile has been set on cross-arm simultaneously, improved the integrated carrying ability of crane span structure; Especially the Y shape bifurcated at flute profile stiffening rib two ends has not only increased the surface of contact on cross-arm and terraced limit; Disperse stressed surface of contact, and improved the bearing strength of cross-arm, need be through just not satisfying the requirement of carrying cable under the situation that increases crane span structure section bar thickness.
Embodiment two
In actual engineering is used,, further improve the bearing capacity of cross-arm 2 in order to prevent the intensity unstability of cross-arm 2 when bearing big cable; The root outer rim is along the reverse reinforced block 5 that is provided with at least one pair of on cross-arm 2 longitudinal directions at the middle part of flute profile stiffening rib 3 on the cross-arm 2.Reverse reinforced block 5 is equivalent to increase reverse stiffening rib in the both sides of flute profile stiffening rib, improves the stability and the bearing strength of crane span structure.
Embodiment three
1 bottom, described terraced limit is L shaped structure, and forms stiffening rib, can certainly have the structure of reinforing function for other, like arc.The stiffening rib of the L shaped structure of ladder limit bottom can limited raising crane span structure bulk strength.Be equipped with inverted U-shaped 6 on the top on two terraced limits 1; Inverted U-shaped on the ladder limit can improve the intensity on terraced limit on the one hand, can avoid scratching the cable that is laid on the crane span structure on the other hand.In addition, for the weight that reduces crane span structure self and easy to use in the cable heat radiation, on terraced limit 1, be provided with some radiation holes 7, this radiation hole 7 is vertically arranged setting along terraced limit.
The utility model has following advantage with respect to traditional ladder-type cable bridge:
