Description
Technical field
The utility model relates to a kind of cable testing bridge, and a kind of large span cable testing bridge, belongs to technical field specifically.
Background technology
Along with the requirement that social economy's ground development and Municipal are planned, for adapting to new development situation and the rigid demand of electricity consumption, underground cable engineering becomes the major way of urban electric power conveying gradually.But gather for the network of waterways, traffic developed regions, cable passage is often intercepted by river course and road, for power channel construction brings larger difficulty.Settling mode general at present adopts horizontal jacking pipe (underground pipe gallery) and directed traction pipe mode to solve, and often adopts truss of angle steel mode to pass through for small-sized river course.But all there is different problems in above several mode.
Angle steel formula crane span structure (single span) span less (15 ~ 20 meters), for the physical dimension obtaining enough rigidity angle steel formula crane span structures must expand, often produces that to exceed road surface, the phenomenon of bridge floor and surrounding enviroment inharmonious.Angle steel formula crane span structure in-site installation plant-on component is more simultaneously, operation is loaded down with trivial details, the construction period is longer, should not construct in heavy traffic section.Because assembly is more, processing, easily produce in assembled process deviation final crane span structure is occurred amount of deflection exceeds standard phenomenon, has a negative impact safely to operation power.
Underground directed traction pipe mode also exists pipeline arrangement and rotates chaotic, and project cost is higher, is constructed into porosity instability problem, and there is inconvenience in environmental protection, road traffic and Coordination by planning.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus provides a kind of large span cable testing bridge, can rapid-assembling at the scene, and shorten the existing construction period, stiffness by itself is comparatively large simultaneously, amount of deflection is less, ensure that construction quality.
According to the technical scheme that the utility model provides, large span cable testing bridge comprises at least three crane span structure segmented assemblies connected successively, it is characterized in that: the two ends of each crane span structure segmented assemblies are respectively equipped with end face of flange, adjacent two crane span structure segmented assemblies are linked into an integrated entity by end face of flange; Crane span structure segmented assemblies comprises the chord member of four settings parallel to each other, two chord members in four chord members are positioned at directly over two other chord member, between two chord members of top and between two chord members of below, be equipped with end web member assembly, between two chord members in side and two chord members at opposite side, be equipped with flank bar assembly; The bottom being positioned at outermost two crane span structure segmented assemblies in described at least three crane span structure segmented assemblies is provided with multiple base for supporting; Multiple cable bearer is provided with along its length in crane span structure segmented assemblies.
Further, end web member assembly comprises the end cross bar of multiple horizontally set, is obliquely installed brace at the bottom of at the bottom of every two between cross bar, and cross bar of multiple ends is evenly arranged.
Further, flank bar assembly comprises the edge-on bar of multiple vertical setting, and be obliquely installed a skew back bar between every two edge-on bars, multiple edge-on bar is evenly arranged.
Further, base for supporting is four, and is uniformly distributed.
Compared with the prior art the utility model has the following advantages:
The utility model structure is simple, compact, reasonable, can rapid-assembling at the scene, shortens the existing construction period; Span is large, and stiffness by itself is comparatively large simultaneously, amount of deflection is less, ensure that construction quality, avoids the destruction to site environment; Cost of manufacture is lower, can create good economic benefit and social benefit.

Description of reference numerals: brace, 7-cable bearer at the bottom of cross bar, 6.2-at the bottom of web member assembly, 6.1-at the bottom of 1-crane span structure segmented assemblies, 2-end face of flange, 3-chord member, 4-base for supporting, 5-flank bar assembly, the edge-on bar of 5.1-, 5.2-skew back bar, 6-.
Embodiment
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As shown in Fig. 1 ~ 4, the utility model mainly comprises at least three crane span structure segmented assemblies 1 connected successively, and the two ends of each crane span structure segmented assemblies 1 are respectively equipped with end face of flange 2, and adjacent two crane span structure segmented assemblies 1 are linked into an integrated entity by end face of flange 2.
Two chord members 3 that crane span structure segmented assemblies 1 comprises in chord member 3, four chord members 3 of four settings parallel to each other are positioned at directly over two other chord member 3.Between two chord members 3 of top and between two chord members 3 of below, be equipped with end web member assembly 6, between two chord members 3 in side and two chord members 3 at opposite side, be equipped with flank bar assembly 5.
Web member assembly of the described end 6 comprises the end cross bar 6.1 of multiple horizontally set, is obliquely installed brace 6.2 at the bottom of at the bottom of every two between cross bar 6.1.Cross bar of described multiple ends 6.1 is evenly arranged.
Described flank bar assembly 5 comprises the edge-on bar 5.1 of multiple vertical setting, is obliquely installed a skew back bar 5.2 between every two edge-on bars 5.1.Described multiple edge-on bar 5.1 is evenly arranged.
The bottom being positioned at outermost two crane span structure segmented assemblies 1 in described at least three crane span structure segmented assemblies 1 is provided with multiple base for supporting 4, in use, the utility model is arranged across river body, be positioned at and need to be fixed on riverbank in outermost two crane span structure segmented assemblies 1, realize stable support by multiple base for supporting 4.In embodiment as shown in Figure 2, described base for supporting 4 is four, and is uniformly distributed.
