Description
Technical field
The utility model belongs to thermal energy material applied technical field, in particular to a kind of main rope of suspension bridge anti-corrosion that is applied to is protected
The aeroge of middle benefit gas.
Background technique
As permanent part non-exchange in Suspension bridge structure, it carries the gravity load and mobile load of girder main push-towing rope
It is transferred to the important task of king-tower and anchorage；Its durability determines the service life of entire bridge, and reliable and effective main cable protection is
Ensure the key of main push-towing rope durability.It is existing to cause whole bridge to scrap because main push-towing rope is unqualified in the suspension bridge that external early stage builds
Example.Wherein mainly the reason is that protection is improper, since corrosion or fatigue rupture cause main push-towing rope to damage, so that full-bridge can not pacify
It entirely uses.The New York Williamsbary bridge being open to the traffic for 1903 is exactly a typical example, and the bridge is until in recent years just not
It obtains and is reused after not expending expensive cost reparation.It is obvious that main cable protection is one for protecting main push-towing rope long-term safety to use
Important process.
Large-span suspension bridge main cable is the major bearing structures of bridge, and performance determines the span ability of suspension bridge and holds
Loading capability, but the variation of temperature on its internal force and linear significantly affects.It is thermally conductive since main rope of suspension bridge is composite structure
Mechanism is more complex, and when ambient temperature changes greatly, main push-towing rope and external environment are carried out with the diversified forms such as convection current and radiation
Heat exchange, the variation of main push-towing rope surface temperature is rapid, but due to main push-towing rope internal temperature transformation hysteresis, and as main push-towing rope diameter becomes larger, stagnant
The more aobvious protrusion of phenomenon afterwards, and then apparent temperature gradient is formed, cause internal-external temperature difference very big.This temperature difference can generate temperature change
Shape can cause main rope of suspension bridge structure stress and linear variation, or even can generate and big temperature stress.This temperature stress
The later period health operation of suspension bridge is influenced with deformation, temperature test result shows that main push-towing rope surface temperature and environment temperature are maximum
Up to 20 DEG C of difference, same strand is along main push-towing rope longitudinal temperature difference very little.At the cloudy day, since solar radiation is weaker, each moment
Main push-towing rope section temperature difference very little, along main push-towing rope longitudinal direction, the temperature difference also very little；In the relatively strong violent situation with variation of fine day intensity of solar radiation
Temperature field is related with time and sectional position；Cheng Qiaohou temperature change has the linear of main push-towing rope, internal force and Sarasota internal force certain
It influencing, main push-towing rope internal force size variation is smaller, and less than the 2% of dead load cable tension, the variation of main push-towing rope sag is substantially suitable with the construction stage,
To its numerical value of engineering is relied on, less than 0.5m, in Clear Days Summer, the safety coefficient that temperature effect will lead to main push-towing rope will reduce by 8%
Or so, moment of flexure is larger at the tower root that influence of the temperature effect to main push-towing rope safety coefficient also results in.
Aeroge (Aerogel) is also known as xerogel, be in the case where keeping gel skeleton structural integrity, will be in gel
Product after solvent seasoning, therefore have the characteristics that nano-porous structure, high porosity, high-specific surface area, 99% is all by gas
Body is constituted, and the hole diameter in material, between 20 ~ 50nm, stomata is hatch frame, unordered and interconnected, outer to watch
Come as cloud, there is translucent color and ultralight weight, has excellent solar heat protection heat-insulated and sound insulation value.It is current
The solid material that known density is minimum, thermal conductivity is minimum, is commonly called as " solid-state cigarette ".Aeroge has high-specific surface area, high hole
Rate, low bulk density have been used as high temperature insulating material, acoustic impedance coupling material, catalyst or catalyst carrier, absorption at present
Agent, filtering material etc..
Aerogel property: 1) it, reduces convection current: when air molecule is in the stomata less than 70nm, free flow will be lost
Dynamic ability, is relatively attached on air vent wall, and at this moment aerogel material is near vacuum state；
2) radiation, is reduced: since the stomata in material is the bulk density that nanoporous adds material itself extremely low again,
So that the material internal air vent wall a few days is tended to " infinite more ", has the function of insulation board for each air vent wall, thus
Generation is bordering on the effect of " infinite more insulation boards ", so that radiant heat transfer be made to drop to intimate lowest limit；
3) heat transfer: the presence due to being bordering on infinite Donna metre hole, is reduced, it just can only be along when hot-fluid transmits in solids
Air vent wall transmitting, is bordering on infinite more air vent wall and constitutes and be bordering on " infinite long path " effect, so that the ability of solid thermal conduction
Drop to close to lowest limit.It is not decomposed under high temperature, no pernicious gas is released, and environmental type material is belonged to；
4), durability: being made of amorphous inorganic silicon dioxide, without can degrade over time as polyurethane foam
Foaming agent, thus the consistency of performance of aeroge and stablize, elastic mechanical performance makes it be easily adaptable to mechanical movement and vibration
It is dynamic, without the sedimentation as perlite.
A kind of aeroge applied in main rope of suspension bridge corrosion-resistant thermal insulation how is designed, how to reduce temperature effect to main push-towing rope
The influence of safety coefficient, reducing temperature effect influences moment of flexure at caused tower root to main push-towing rope, and how to extend main push-towing rope uses the longevity
Life, becomes urgent problem.
Summary of the invention
