Abstract
The utility model relates to an electric cable bridge, which comprises a bridge body with channel steel profile cross sections. The bottom surface of the bridge body is provided with air holes and reinforcing ribs protrude upwards, the upper ends of two side plates of the bridge body are provided with flanged edges and the two side plates of the bridge body are provided with reinforcing ribs protrude inwards or outwards. Through changing the structure of side faces, the integral longitudinal bending strength of the bridge body can be enhanced and the carrying capacity can be raised substantially. Because the bottom flat surface is provided with one rectangular reinforcing rib at intervals protrudes upwards, the bending strength of the bottom flat surface is increased, bending and changing because of weight are effectively prevented and the defect of the prior art is effectively solved. The utility model has the advantages of light weight, high capability and simple structure.
Description
One, technical field: the utility model relates to a kind of cable testing bridge.
Two, background technique: crane span structure is widely used in multiple industries such as communication, electric transmission line as the cable routing supporting mass.The tradition crane span structure mostly is the grooved body of a bridge, and crane span structure three faces are slab construction, has that structure weight is big, cost is high, bearing capacity and weight is disproportionate, and difficult or the like a series of problems are installed.The patent No. is: 02284140.7 model utility proposes a kind of pellet type cable testing bridge, and stiffening rib is set on the crane span structure tray bottom surface in order, and wherein stiffening rib is oval flute profile, presses the vertical and horizontal dual mode and distributes.Thereby the bearing power and the intensity that improve whole crane span structure reach the purpose that alleviates the deadweight convenient construction.
The patent No. is: 01213106.7 model utility mainly contains " U " shape body of a bridge, bar shaped connecting plate and two blocks of side plates constitute, the sidewall middle part of " U " shape body of a bridge is provided with stiffening rib and air hole, the base plate both sides are symmetrical arranged stiffening rib, be vertically arranged with and the vertical vertical elongate recesses of the body of a bridge along body of a bridge middle part, be provided with a plurality of mounting holes in the elongate recesses, between stiffening rib and the elongate recesses, be vertically arranged with strip groove with body of a bridge vertical consistency, be provided with mounting hole in the strip groove along the body of a bridge.This technological scheme preferably resolves that original cable testing bridge weight is big, cost is high, the problem of intensity difference, installation inconvenience.
But also there is some shortcoming in these above-mentioned two kinds of schemes, and vertically resistance to flexure is not enough, can't fundamentally solve the problem that carrying can be lower.
Three, the content of model utility:
The purpose of this utility model: overcome the problem that the existing cable crane span structure exists, provide a kind of bearing capacity big and resistance to flexure is good, the cable testing bridge of long service life.
The technical solution of the utility model is: a kind of cable testing bridge, the bridge formation body that contains the channel-section steel transverse section of section material, be provided with air hole and stiffening rib protruding upward in crane span structure body bottom surface, panel upper end, crane span structure body both sides is provided with flange, the stiffening rib that is provided with inwards or outwards protrudes on the panel of the both sides of crane span structure body.
Being provided with cross section inwards one or more or that outwards protrude on two side plates of crane span structure body is the stiffening rib of opening isosceles ladder type.
Can also be provided with cross section inwards one or more or that outwards protrude on two side plates of crane span structure body is the stiffening rib of open semi circle or arc.
Can also be provided with cross section inwards one or more or that outwards protrude on two side plates of crane span structure body is the stiffening rib of opening isosceles triangle or opening equilateral triangle.
On crane span structure body bottom surface, be provided with uniform air hole, be slotted eye, or be the long strip hole, or be circular hole, be provided with the stiffening rib of flat " mouth " font protruding upward at a certain distance.
The beneficial effects of the utility model: because the stiffening rib that on the panel of the both sides of crane span structure body, has increased inwards or outwards protruded, change the force structure of side plate, increase crane span structure body cross section bending resistance square amount, strengthen the whole vertically resistance to flexure of crane span structure body, increased substantially bearing capacity; Be provided with the stiffening rib of flat " mouth " font protruding upward at a certain distance in base plane, increase the base plane resistance to flexure, effectively prevent to be subjected to heavily to scratch change; Uniform air hole improves gas permeability, the needs that satisfy heat radiation, leak.So under equal conditions, intensity can improve more than 50 percent, has outstanding advantages such as in light weight, that bearing capacity is big, and simple in structure, cost is lower, has remarkable economical and social benefit.

Five, embodiment
Embodiment one: referring to Fig. 1, Fig. 2, among the figure: 1 is the base plate of crane span structure body, 2 is two side plates of crane span structure body, 1 and 2 form flute profile basic structure body, 3 is the upper end flange of side plate 2,4 is the long strip air hole of crane span structure body base plate 1, the 5 opening isosceles trapezoid stiffening ribs that protrude inwards that are provided with for crane span structure side panel 2 (or outwards outstanding), 6 flat " mouth " font stiffening ribs that are provided with for crane span structure base plate 1.
Embodiment two: referring to Fig. 1, Fig. 3, the meaning of the representative that numbering is identical with embodiment one among the figure is identical, does not repeat.Have not be that two opening isosceles trapezoid stiffening ribs 5 that protrude inwards at a distance of certain distance (or outwards outstanding) are arranged in crane span structure side panel 2.
Embodiment three: referring to Fig. 1, Fig. 4, the meaning of the representative that numbering is identical with embodiment one among the figure is identical, does not repeat.Have not be that two circular stiffening ribs 5 of the open semi that protrudes inwards at a distance of certain distance (or outwards outstanding) are arranged in crane span structure side panel 2.
Embodiment four: referring to Fig. 1, Fig. 5, the meaning of the representative that numbering is identical with embodiment one among the figure is identical, does not repeat.Have not be that two opening isosceles triangle stiffening ribs 5 that protrude inwards at a distance of certain distance (or outwards outstanding) are arranged in crane span structure side panel 2.
