Description
Technical field
The present invention relates to a kind of light shock-proof jacket bases using overlap joint pipe node completely, belong to ocean engineering technology
Field.
Background technology.
In recent years, wind energy is because its cleaning, reproducible feature become the weight for alleviating Global Environmental Problems and energy problem
One of energy is wanted, ocean area is vast, and sea wind resource is stablized, and generated output is big, and offshore wind farm is developed rapidly all over the world.Mesh
Before, the basis of offshore wind turbine is usually single-pile foundation, more pile foundations, cylindrical foundation, buoyant foundation and jacket basis, the depth of water
Offshore wind turbine foundation in 30m to the marine sites 70m generally selects jacket basis.Conventional pilot pipe support basis mostly uses X-type or K-type pipe
Node, technology maturation, stable structure, resistance to capsizing is strong, adapts to various seabottom geology conditions.But it to be welded on jacket leg
Diagonal brace and horizontal brace, weld seam quantity compare concentrations more, it is necessary to thicken at node jacket leg to ensure structural strength, increase technique
Difficulty increases the manufacturing cycle and increases production cost, and under severe marine environment and complex working condition, active in earthquake
Area, the anti-fatigue ability and shock resistance on conventional pilot pipe support basis are limited, and structure safety problem is faced with formidable challenges.
Invention content
In order to overcome the shortcomings of that conventional pilot pipe support basis, the present invention provide a kind of using the light-duty anti-of overlap joint pipe node completely
Shake jacket basis, the light shock-proof jacket basis should have simple and stable structure, intensity height, light weight, manufacturing cycle it is short,
The features such as anti-seismic performance and good anti-fatigue performance.
The technical solution adopted by the present invention is：A kind of light shock-proof jacket basis using overlap joint pipe node completely, it
Including jacket leg, main brace, secondary diagonal brace, the first diagonal brace and first level support, the second horizontal brace, third horizontal brace, the 4th water
It supports, the 5th horizontal brace, the jacket leg on the light shock-proof jacket basis uses intilted upright bar, and two adjacent lead
It is fixedly connected using multiple main braces between pipe support leg, one layer of second horizontal brace of use and conduit on light shock-proof jacket basis
Frame leg level is fixedly connected, and is fixedly connected with the 5th horizontal brace on the inside of the intermediate point that two adjacent first levels support, two layers
The second horizontal brace is all made of with top layer to be fixedly connected with jacket leg level；Using secondary diagonal brace between two adjacent main braces
It is fixedly connected, one end of secondary diagonal brace is connected to the lower end of a main brace, and the other end of secondary diagonal brace is connected to another main brace
Upper end；Between one layer and two layers of light shock-proof jacket basis, V-shaped, V words are constituted using two the first diagonal braces per side
Lower end be fixedly connected on one layer of first level support centre position, the upper end of V words is fixedly connected under two layer of second horizontal brace
The jacket leg of side.
The quantity of the jacket leg is three, constitutes three leg light shock-proof jacket bases.
The quantity of the jacket leg is four, constitutes four leg light shock-proof jacket bases.
The four legs light shock-proof jacket basis from two layers upwards to top layer, every layer between two opposite jacket legs
It is all fixedly connected with third horizontal brace, is fixed respectively with one end of two the 4th horizontal braces between the opposite jacket leg of another two
The other end of connecting conduit frame leg, two the 4th horizontal braces is all fixedly connected on the centre position of third horizontal brace.
The beneficial effects of the invention are as follows：Three leg jacket basis and four leg's jackets basis belong to light shock-proof and lead
Pipe support basis, has been all made of complete overlap joint pipe node, the exactly difference of pipe node form, has led to the structure and conventional pilot pipe support
Structure the difference is that not every horizontal brace both ends are all directly welded on jacket leg, but it is adjacent by being partly welded on
Horizontal brace on jacket leg is changed to the secondary diagonal brace that both ends are welded on neighbouring main brace, the inclined degree of secondary diagonal brace according to
The lap of splice of overlap joint pipe node completely requires to determine.The above-mentioned optimization to connection type and structure integrally changes outside
Load transport mechanism inside jacket structure makes lateral external load mainly be transmitted between main brace and secondary diagonal brace, and
Jacket leg is f hardlyed pass through, and main brace and secondary diagonal brace can also share part vertical load, mitigate the pressure of jacket leg,
To protect the main member of jacket structure, structural ultimate bearing capacity is improved, while conduit at pipe node can be effectively reduced
Material is saved in the increase of frame leg wall thickness, mitigates dead load, simplifies technique, is shortened the production cycle, is reduced cost.In addition, passing through
The deformation of the main brace tube wall of lap position, absorbs and discharges a large amount of external energies, this can significantly improve the anti-seismic performance of structure
And anti-fatigue performance, and can be by adjusting composition the jacket leg of overlap joint pipe node, main brace and secondary diagonal brace three completely
Wall ratio, diameter than, radius wall ratio, the lap of splice optimize structure anti-seismic performance and fatigue behaviour.
