The utility model has the advantages of(1) structural integrity with high rigidity, obvious force transmission, relatively huge lateral force resistance capacity, (2) even rigidity distribution, (3) simple structure, convenient construction, (4) relatively high wind resistance and vibration resistance, (5) high stability and comprehensiveness, material saving, cost reduction and economic and durable structure.
Description
(1) technical field
The utility model relates to a kind of braced structures of fixed offshore platform, particularly a kind of giant frame structure conduit rack of deep-sea fixed offshore platform.
(2) background technology
Giant frame structure is that the simple and huge truss formed with huge member or frame construction are as agent structure, the cooperative a kind of structural system of aggregated(particle) structure with other structural element compositions, its main structure is main lateral resisting system, aggregated(particle) structure is only born vertical load, and is responsible for its load of bearing is passed to main structure by huge beam.Therefore, giant frame structure is a kind of unconventional large scale structure with huge lateral resisting rigidity and integral working.Because giant frame structure has good performance, is used widely in the highrise building of land, obtains good economic and social benefit.
In recent years, because expanding economy, the demand of oil is cumulative year after year also.In order to adapt to the social development and the supply of the energy, many countries invest resourceful ocean to the sight of oil development, have built many offshore oil platforms.The platform building is subjected to the effect of multiple load in the abominable ocean of environment.Summary is got up, and causes that platform vibration and the load of destroying mainly contain following several: earthquake, wave, wind-force, ice carry and platform on the excitation load that produces of machine and equipment running.As a rule, the load that platform is subjected to is not single, but the synergy of multiple load.Under the synergy of multiple load, platform structure will produce violent vibration.The lighter allows the workman produce fear, and weight person can cause the fatigue failure of platform structure, the disaster that causes platform to collapse.
Fixed platform is the most frequently used a kind of ocean platform, and braced structures is a steel jacket, generally is the space rigid structure that is welded with the high-quality steel.Its function mainly is that the superstructure for ocean platform provides support.Electromechanical equipment has a good and lasting working environment on the platform in order to make, and just must make jacket have enough strength and stiffness, so that keep safety and stable under the effect of bearing huge superstructure gravity and environmental load.
China builds up first fixed jacket platform from 1966 in Bohai Sea Gulf, has the history in more than 40 year.The ocean platform that has completed for use in the meantime has tens, and structural shape mainly is a steel jacket formula fixed platform, is mainly used in the more shallow marine site of the depth of water.Along with oil exploration and exploitation to than deepwater field development, the development of jacket platform faces many difficulties and insoluble problem.
(1) along with the increase of the depth of water, the cost of steel conduit body panel structure can sharply rise, and marine transportation and activity duration prolong, and is subjected to the influence of environment to become big.
(2) ocean platform is vertically arranged semi girder generally, and along with increasing of structure becomes big, bending rigidity descends, and the lateral resisting ability reduces, and increase natural vibration period, moves closer to the vibration frequency of wave, therefore can cause resonance.
(3) increase of structure can make the long-pending increase of fluoran stream surface of constitution water lower part.The increase that fluoran stream surface is long-pending, drag force, inertia force and diffraction force that wave is acted on the platform increase, and increase the weight of the horizontal loading that platform bears, and cause the vibratory response that platform and integrally is excessive, finally cause the fatigue failure of platform structure.
(3) summary of the invention
The utility model is in order to overcome the deficiency of above technology, provides that a kind of each spud leg is stressed littler, and is more even under non-homogeneous level and vertical load effect, has the giant frame structure conduit rack of reasonable static characteristic.
The utility model is realized by following measure:
Giant frame structure conduit rack of the present utility model, form by main frame and time framework, its special feature is: described main frame is made up of pillar construction and 2-6 layer trussed construction, described pillar construction is that the huge post by 6～20 settings constitutes, and described trussed construction is by being welded on the huge post and constituting with the perpendicular huge beam of huge post; Inferior framework is the platform that is placed in the trussed construction top.
Giant frame structure conduit rack of the present utility model, the height of described huge post are 60-500m, and described trussed construction is a height 4-20m space lattice truss, and the floor height of trussed construction is 20-60m.Preferred version is: the height of described huge post is 100-300m, and described trussed construction is a height 5-15m space lattice truss, and the floor height of trussed construction is 30-50m.
Giant frame structure conduit rack of the present utility model, described huge post are that diameter 1000～3000mm, wall thickness are the steel pipe of 15～30mm, and described huge beam is that diameter 500～2000mm, wall thickness are the steel pipe of 10～25mm.Preferred version is: described huge post is that diameter 1500～2500mm, wall thickness are the steel pipe of 15～30mm, and described huge beam is that diameter 500～1500mm, wall thickness are the steel pipe of 10～25mm.
This utility model is introduced giant frame structure in the design of deep-sea jacket, the anti-side ability of shaking of jacket is improved greatly.This jacket is made up of main frame and time framework; Main frame is made of huge post and huge beam, is main bearing structure, has very strong anti-side rigidity, can effectively bear vertical load and opposing horizontal load; Platform superstructure and jacket main frame connect, and form time framework or aggregated(particle) structure.Inferior framework or aggregated(particle) structure are only born the load of itself and are given main frame loading transfer.The work of primary and secondary structural coordination, it is even, rational in infrastructure to constitute rigidity, the mechanical structure system that power transmission is clear and definite.This jacket is under non-homogeneous level and the effect of vertical static load lotus, and each spud leg is stressed littler, and is more even, has reasonable static characteristic; Little and the coordination of first three first order mode distortion has reasonable rigidity quality matches, does not have vibration shape distortion phenomenon to produce, and has reasonable dynamic property.
Effect of the present utility model: giant frame structure has good compliance and stock utilization efficiently, receives increasing concern.Summarize in fact, giant frame structure has following salient feature:
(1) structural entity rigidity is big, and power transmission is clear and definite, has stronger lateral resisting ability.
(2) Stiffness Distribution is even, has reasonable reconciling spatial scale.
(3) simple in structure, easy construction is convenient to shorten construction period.
(4) have reasonable wind resistance, anti-seismic performance.
(5) have bigger stability and higher combination property, can save material, reduce cost, make the works economy and durability.
