Description
Technical field
The invention belongs to cable testing bridge, more particularly to double terraced side large span steel cable bridges.
Background technology
Cable testing bridge is divided into the structures such as slot type, pellet type and ladder-type, grid type, by support, trailing arm and installation annex etc.
Composition.Step type cable bridge frame has the advantages that in light weight, cost is low, moulding does not have, be easy for installation, radiated, be ventilative good.He is suitable
For being typically relatively large in diameter the laying of cable, it is suitable for the laying of high and low pressure power cable.Tray type cable bridge be oil,
The most widely used one kind of chemical industry, light industry, telecommunication etc..It has in light weight, load is big, it is handsome in appearance, simple in construction, peace
Fill the advantages that facilitating.It suitable for the installation of power cable, is also suitable for controlling the laying of cable.Channel-type cable bridge is one
Kind Totally-enclosed-type cable testing bridge.It is best suited for laying computer cable, communication cable, thermocouple cable and other highly sensitive systems
Control cable of system etc..It has preferable effect to the protection for shielding environmental cable in interference and heavy corrosion for controlling cable.
The respective advantage and disadvantage of ladder-type, pellet type, channel-type cable bridge：Ladder-type bus bar installation casing has a good performance of ventilating, not dust-proof,
It is not anti-tampering.Slot type, pellet type bus bar installation casing have dust-proof, anti-tampering performance.
Current large span cable bridge rack is usually to be assembled by pulling and extruding glass fiber section bar, suitable for power cable, control
Cable, light conduits and accessory etc..Compared with iron crane span structure, there is service life length (being typically designed the life-span as 20 years), peace
Dress is convenient and cost low (proportion is only the 1/4 of carbon steel, need not be got angry in construction, and single crane span structure length is up to 8 meters, even more
It is long), the superiority such as cutting is convenient, is not required to safeguard, but cost is very high, and price is 3 times of steel cable bridge.
The content of the invention
It is an object of the invention to：It is proposed that one kind is easy for installation, structure is reliable, stress performance is excellent, and cost significantly drops
Low large span steel cable bridge.
The object of the invention is realized by following technical proposals：
A kind of station shelter large span crane span structure, including be arranged in below shelter with the crane span structure of shelter Longitudinal extending,
Crane span structure is formed by connecting by more piece trough type bridge frame, and it is 9 meters~12 meters often to save trough type bridge frame length with shelter span, wind and rain booth structure
The reserved opening for allowing trough type bridge frame to pass through is offered in crossbeam, two adjacent sections trough type bridge frame connecting portion sets the reserved opening
In, connecting portion bottom using steel plate as leveling pad and both ends it is exposed, and be subject to anti-skidding crab-bolt be fixedly connected ensure surely
Fixed, connecting portion also connects ground connection copper strap wire by crane span structure connection sheet and is grounded with shelter post；
Trough type bridge frame includes the cell body and cover plate of steel, cell body and cover plate by welding cover plate pintle hook lock buckle-type thereon
Fixed closed, the cavity closed between cell body and cover plate are the passage of current supply cable extension；Two cell walls of cell body be respectively equipped with
The hollow circular-tube structure that cell wall is integrally formed and extended longitudinally with cell wall, it also is provided with extending laterally in the bottom land of cell body some
The hollow circular-tube structure that parallel interval is set.
Alternatively, the reserved opening in each shelter structural beams is located on unified absolute altitude and axis.
Alternatively, the hollow circular-tube structure on cell wall is two, and the hollow circular-tube structure on bottom land is equidistantly uniformly divided
Cloth.
Alternatively, reserved opening size high major 20mm wider than trough type bridge frame.
The foregoing main scheme of the present invention and its each further selection scheme can be this with independent assortment to form multiple schemes
The scheme that invention can be used and is claimed；And the present invention, between (each non conflicting selection) selection and between other selections
Can also independent assortment.Those skilled in the art can understand have after the present invention program is understood according to prior art and common knowledge
Multiple combinations, it is the claimed technical scheme of the present invention, does not do exhaustion herein.
Beneficial effects of the present invention：It is easy for installation, the large span cable bridge of relatively current conventional pulling and extruding glass fiber section bar
Frame, structure is more reliable, stress performance is more excellent, and cost is greatly reduced.

Embodiment
Following non-limiting examples are used to illustrate the present invention.
With reference to shown in figure 1-4, a kind of station shelter large span crane span structure, including the lower section of shelter 1 is arranged in shelter 1
The crane span structure of Longitudinal extending, crane span structure are formed by connecting by more piece trough type bridge frame 2, and it is 9 meters often to save the length of trough type bridge frame 2 with shelter span
~12 meters, the reserved opening 4 for allowing trough type bridge frame 2 to pass through, two adjacent sections trough type bridge frame 2 are offered in the structural beams 3 of shelter 1
Connecting portion is set in the reserved opening 4, and connecting portion bottom is used as leveling pad using steel plate 5 and both ends are exposed, and is subject to
Anti-skidding crab-bolt 6, which is fixedly connected, ensures stabilization, and connecting portion also connects ground connection copper strap wire 8 and shelter post 9 by crane span structure connection sheet 7
Ground connection；
With reference to shown in figure 1,4, trough type bridge frame 2 includes the cell body and cover plate of steel, cell body and cover plate by welding thereon
Cover plate pintle hook lock buckle-type fixed closed, the cavity closed between cell body and cover plate be current supply cable extension passage；In cell body
Two cell walls 21 are respectively equipped with the hollow circular-tube structure 22 for being integrally formed with cell wall 21 and being extended longitudinally with cell wall 21, in cell body
The hollow circular-tube structure 22 that some parallel intervals that bottom land 23 also is provided with extending laterally are set.Preferably, the sky on cell wall 21
Heart circular tube structure 22 is two, and the hollow circular-tube structure 22 on bottom land 23 is equidistantly uniformly distributed.
Embodiment 1：
As an example, certain engineering uses trough type bridge frame wide 150mm, high 100mm, it is 9 meters often to save length with shelter span
~12 meters.In the construction of large span crane span structure, it is desirable to which the reserved opening size that shelter wears Liang Chu is unified for wide 170mm, high
120mm, blocked after crane span structure installation, then by unnecessary gap；And in order to ensure the straight of crane span structure installation, constructing
Before need unwrapping wire to confirm all reserved openings all on unified absolute altitude and axis.The length of large span crane span structure is according to shelter axis of a cylinder
Away from setting.Crane span structure connecting portion is arranged in shelter structural beams, and bottom is using 6mm steel plates as leveling pad and two
Hold exposed each 50mm, and be subject to 8 anti-skidding crab-bolts of φ be fixedly connected ensure stabilization.Bridge cover plate is fixed using welding buckle-type, with
Ensure its stability.After crane span structure installation, reserved opening surrounding is blocked and brushes corresponding coating.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
