Description
Technical field
The utility model is related to technical field of bridge engineering, specially a kind of girder severe and rigidity function separate type lightweight
Short beam suspension bridge.
Background technology
It is larger to often require that beam body has for the system stiffness for making it have enough as flexible load-carrying members for suspension bridge
Height and severe, this not only expends a large amount of initial construction material (girder material is often high-strength steel), and it is excessive from
Weight also consumes the bearing capacity of beam body itself.Huge beam body not only spends substantial contribution, and increases processing, making, fortune
Defeated, installation difficulty all has challenge to means of transport, mode of transportation, carrying and lifting equipment etc., beam body is overweight be not easy across
More construct, increase difficulty of construction, the duration increase and it is difficult in maintenance, total life cycle is of high cost.High-strength light construction material is difficult to
It promotes, use in beam body.
It is interior from anchor suspension bridge (application number 201610613624.X, 201620807180.9) using interior from anchor formula, save
Bulky anchorage so that have different geological conditions compared with strong adaptability.Compared with the anchor suspension bridge of original place, rope is decreased
Pressure of the tower to ground.But since main push-towing rope is anchored on stiff girder, beam bears prodigious axial force, needs to increase cutting for beam thus
Face causes girder dead weight to obviously increase, and economic cost can also greatly improve.And construction technology is complicated, lifting main push-towing rope, installation hoist cable
Must stiff girder, bridge tower carry out after carry out again, it is therefore desirable to build a large amount of falseworks to install stiff girder, cause greatly across
It is excessive to spend structure construction expense.
Utility model content
In view of the deficiencies of the prior art, the technical issues of the utility model intends to solve be to provide a kind of girder severe with just
Spend the short beam suspension bridge of function separate type lightweight.
The technical solution that the utility model solves the technical problem is to provide a kind of girder severe and is detached with rigidity function
The short beam suspension bridge of formula lightweight, including girder, main push-towing rope and sunpender；Main push-towing rope is located at the both sides of girder center line or transverse direction；The sunpender
One end connect with main push-towing rope, the other end is connect with girder；It is characterized in that the suspension bridge further includes carrying apparatus；The loading dress
It sets on sunpender；Each carrying apparatus is mutual indepedent；Weight is filled inside the carrying apparatus；The quality and girder of weight
The quality positive correlation of mitigation；Carrying apparatus is longitudinally uniformly distributed along main push-towing rope, the carrying apparatus on every sunpender and its internal weight
Gross mass it is equal, each sunpender stress is equal, convenient for sunpender use same size sectional dimension；The carrying apparatus and master
Beam is independently of each other without contact.
Compared with prior art, the utility model advantageous effect is：
(1) it need to will be substituted originally by independent carrying apparatus by the overall structure gravity stiffness that girder severe is contributed, girder
Without providing overall stiffness, it is only necessary to smaller local mobile load rigidity is provided, to be divided the function of girder severe and rigidity
Sectional dimension from, girder determines according to bridge floor rigidity of the suspension bridge needed for the mobile loads such as operation stage vehicle, crowd, then
The big girder of original weight amount and height can be substituted for light-duty short girder, substantially reduce deck-molding and sectional dimension, save lot of materials,
Mitigate girder dead weight, reduce cost, reduces processing, makes, the difficulty of transport and installation, easy construction simple in structure, beam body is easily tieed up
Shield maintenance, and the landform such as hills, valley are adapted to, it solves light building material and is difficult to be suitable for the awkward situation of girder of suspension bridge,
Especially suitable for large-span suspension bridge.
(2) carrying apparatus can reduce the center of gravity of structural system, the stability of enhancing structure, streamlined structure using spheroid
Conducive to wind resistance.Spheroid installation is more loose to absolute altitude precision prescribed, and main push-towing rope deformation is small during erection of main beam thereafter, convenient for applying
Industry control system.Weight can be directly put on the pontoon under bridge in water by spheroid when safeguarding, directly replaced or repaired, avoid high-altitude
Operation, it is convenient to carry out.If under-clearance is met the requirements, spheroid also may be provided in navigation section.
(3) carrying apparatus uses empty cylinder or continuous flexible cylinder on under-clearance without influence, is more easy to meet navigation requirement.
(4) waste construction material or larger material, stone, the water body etc. of color density can be used in weight, convenient for taking nearby
Material is conducive to environmental protection.
(5) stablize hinge and connector as with the independent suspension element of sunpender, separately maintain or replace convenient for the later stage.
