The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model technical scheme being carried out detailed description, with purpose, scheme and the effect of further understanding the utility model, but is not the restriction as the utility model accompanying claims protection domain.
Consult the constructional drawing of the semisubmersible platform of Fig. 2 the utility model; As shown in the figure; The semisubmersible platform of the utility model comprises following buoyancy aid 10 and is connected in down the column 20 on the buoyancy aid 10, because the main inventive point of the utility model is the connection mode of column 20 and following buoyancy aid 10; Therefore, other detailed structure of relevant semisubmersible platform is just seldom done and is given unnecessary details.
In conjunction with consulting Fig. 3 a to Fig. 4 d; The column 20 of the utility model is all arc with all junctions of following buoyancy aid 10 and is connected; Specifically, be connected to form said arc with second connection structure 50 through first connection structure 40 between column 20 and the following buoyancy aid 10 with shape of a saddle outside plate 51 with arc outside plate 41.Can find out through Fig. 2; Column 20 forms arc with the common junction (like the junction among Fig. 2 31,33) of following buoyancy aid 10 through first connection structure 40 and is connected, and column 20 forms the arc connection with the flex point place (like the junction among Fig. 2 32,34) that is connected of following buoyancy aid 10 through second connection structure 50.
Consult Fig. 3 a to Fig. 3 c; First connection structure 40 comprises arc outside plate 41, first brace panel 42 and second brace panel 43; First brace panel 42 and second brace panel 43 all have the curved portions adaptive with the curved profile of arc outside plate 41 (like the curved portions 431 among the curved portions among Fig. 3 b 421 and Fig. 3 c); First brace panel 42 and second brace panel 43 are connected in the inboard of arc outside plate 41 through curved portions separately, and the inboard here is and the exposed surface of column 20 or the relative side of exposed surface of buoyancy aid 10 down.First brace panel 42 comprises first plate body 422 and second plate body, 423, the first plate bodys 422 and arc outside plate 41 direct connections, and second plate body 423 is connected with first plate body 422 makes the first brace panel cross section be the T type.Preferably, first brace panel 42 is processed by the T section bar, and second brace panel 43 is processed by profile material.
Consult Fig. 4 a to Fig. 4 d; Second connection structure 50 comprises shape of a saddle outside plate 51, the 3rd brace panel 52 and the 4th brace panel 53; The 3rd brace panel 52 and the 4th brace panel 53 all have the curved portions (like curved portions 531 in curved portions in Fig. 4 c 521 and Fig. 4 b) adaptive with shape of a saddle outside plate 51; The 3rd brace panel 52 and the 4th brace panel 53 are connected in the inboard of shape of a saddle outside plate 51 through curved portions separately, and the inboard here is and the exposed surface of column 20 or the relative side of exposed surface of buoyancy aid 10 down.The 3rd brace panel 52 comprises the 3rd plate body 522 and the 4th plate body 523; The 3rd plate body 522 and shape of a saddle outside plate 51 direct connections; And the 3rd plate body 522 is away from having recess 5221 on shape of a saddle outside plate 51 1 sides; The 4th plate body 523 is connected in the recess 5221, and the 4th plate body 523 with make the 3rd brace panel 52 cross sections be the T type after the 3rd plate body 522 is connected.Preferably, the 3rd brace panel 52 is processed by the T section bar, and the 4th brace panel 53 is processed by profile material.
The utility model so there is not the junction of bearing along steel plate thickness direction pulling force, promptly need not adopt expensive " Z " to steel because the junction does not exist and is interrupted continuous problem.
In addition; The outside plate of the common junction of column 20 and following buoyancy aid 10 adopts the arc plate structure of unidirectional 2.5 meters radiuses; Inside is strengthened with the T section bar and the profile material of 750 millimeters of spacings; Relatively prior art adopts rolling section bar such as bulb flat to connect to have to be difficult to solve the problem of processing difficulties along corresponding radian bending problem.And the circular arc place that the flex point place can carry out the transition to the edge that descends buoyancy aid 10 junction always that is connected of column 20 and following buoyancy aid 10 finally forms beautiful shape of a saddle flex point, has solved the fatigue problem at flex point place effectively, and needn't periodically change bracket.
