The upper end of diagonal brace；Between one layer and two layers of light shock-proof jacket basis, every side constitutes V word using two the first diagonal braces
Shape, the lower end of V word are fixedly connected on the middle position of one layer of second horizontal brace, and the upper end of V word is fixedly connected on two layer of first water
Support the jacket leg of lower section.
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 between the opposite jacket leg of another two with one end of two the 4th horizontal braces
The other end of connecting conduit frame leg, two the 4th horizontal braces is all fixedly connected on the middle position of third horizontal brace.
The beneficial effects of the utility model are: three leg jacket basis and four leg's jackets basis belong to light-duty resist
Jacket basis is shaken, complete overlap joint pipe node, the exactly difference of pipe node form has been all made of, the structure is caused to be led with tradition
Pipe frame structure the difference is that not every horizontal brace both ends are all directly welded on jacket leg, but will partially be welded on
Horizontal brace on adjacent catheter frame leg is changed to the secondary diagonal brace that both ends are welded on neighbouring main brace, the inclined degree of secondary diagonal brace
It is required according to the lap of splice of complete overlap joint pipe node to determine.The above-mentioned optimization to connection type and structure, integrally changes
External loads transport mechanism inside jacket structure passes lateral external load mainly between main brace and secondary diagonal brace
It passs, and f hardlyes pass through jacket leg, and main brace and secondary diagonal brace can also share part vertical load, mitigate jacket leg
Pressure improves structural ultimate bearing capacity, while can effectively reduce at pipe node to protect the main member of jacket structure
Material is saved in the increase of jacket leg wall thickness, mitigates dead load, simplifies technique, is shortened the production cycle, is reduced cost.In addition,
By the deformation of the main brace tube wall of lap position, a large amount of external energies are absorbed and released, this can significantly improve the antidetonation of structure
Performance and anti-fatigue performance, and can be by adjusting the jacket leg, main brace and secondary diagonal brace for constituting complete overlap joint pipe node
The wall ratio of three, diameter than, radius wall ratio, the lap of splice optimization structure anti-seismic performance and fatigue behaviour.
