Specific embodiment
With reference to the accompanying drawing, the present invention is further illustrated by way of embodiment, but is not therefore limited the invention to
Among following scope of embodiments.
As shown in Figs 1-4, SPAR main platform body 500 includes: hard cabin 510, truss 520 and soft cabin 540, and truss 520 includes
Multistage pipe frame structure 521 and the heave plate 530 between adjacent pipe frame structure 521.
Method of construction includes the following steps:
Step 100: hard cabin 510 being divided into multiple ring segments 511 and is built.
Hard cabin 510 is divided into multiple ring segments 511 in the longitudinal direction, wherein in addition to the ring segment farthest away from truss 520
Except 511, remaining ring segment 511 is equal in length.Line Q1 with the arrow is the dividing line of ring segment 511 in Fig. 1.
In the present embodiment, by taking length is 95m, diameter is the hard cabin 510 of 39.6m as an example.Hard cabin 510 is divided into 5 rings
Section 511,511 length of ring segment farthest away from truss 520 are 17m, and the length of remaining ring segment 511 is 19.5m.The length of ring segment 511
Equal to be conducive to mass construction, efficiency is higher.The segmentation circulation maximum length in general shipyard is 20m, and therefore, selection connects
Length of the value of nearly segmentation circulation maximum length as ring segment 511.
Each ring segment 511 in hard cabin 510 is divided into four first segmentations 512, the size phase of each first segmentation 512
Deng, and the dividing line of the first adjacent segmentation 512 avoids large-scale girder.Line Q2 with the arrow is drawing for the first segmentation 512 in Fig. 2
Separated time.
Each first segmentation 512 is divided into two second segmentations 513, the dividing line of the second segmentation 513 and the first segmentation
The distance of 512 center line is h, h 100mm.In this way, bulkhead can be avoided.Line Q3 with the arrow is the second segmentation in Fig. 3
513 dividing line.
Step 200: the ring segment 511 for building the hard cabin 510 completed is sequentially connected fixation.
A through channel is formed in hard cabin 510.
When ring segment 511 is sequentially connected fixed, by constantly measuring and calibrating, so that the wall of through channel is maintained at one
In plane.
Step 300: truss 520 is installed on to the one end in hard cabin 510.
Pipe frame structure 521 includes four standpipes 522 and the strengthening frame 523 for being connected to two adjacent standpipes 522.
Truss 520 is installed in the following manner:
Underlying two standpipes 522 it will be connected in the mounted state with hard cabin 510 and heave plate 530；
The strengthening frame 523 being positioned between two standpipes 522 of lower section；
Erect in the mounted state two strengthening frames 523 are respectively installed to underlying two standpipes 522；
It is mounted on two standpipes 522 being located above under installation condition；
The strengthening frame 523 being located above in the mounted state is installed between two standpipes 522 being located above；
Wherein, installation condition is placement status of the SPAR main platform body 500 when being mounted.
Later, the pipe frame structure 521 installed between two pieces of heave plates 530 is also installed in the above-described manner, is first installed two and is stood
Then pipe 522 successively installs strengthening frame 523 from bottom to up.
Finally, the pipe frame structure 521 between installation heave plate 530 and soft cabin 540, mounting means is also as above.
Strengthening frame 523 is that multiple pipe fittings intersect fixed structure.
The structural strength of strengthening frame 523 between two heave plates 530 is greater than adding between heave plate 530 and hard cabin 510
Gu the structural strength of the strengthening frame 523 between the structural strength or heave plate 530 and soft cabin 540 of frame 523.That is, two heave plates
The pipe fitting in strengthening frame 523 between 530 is more than the pipe fitting or heave plate of the strengthening frame 523 between heave plate 530 and hard cabin 510
The pipe fitting of strengthening frame 523 between 530 and soft cabin 540.
Heave plate 530 is the construction of anti-state.Here anti-state is built opposite with normal state construction.Normal state construction is will to need to build
Component built upwards from the lower section of its use state, the orientation of the component after the completion of building is exactly the side of its use state
Position.
And anti-state construction is that the component that will need to build is built downwards from the top of its use state, after the completion of building
It turns upside down with the orientation of its use state in the orientation of component.
Step 400: soft cabin 540 is installed on truss 520.
Soft cabin 540 is divided into upper platform by level height and bottom is segmented, the anti-state of upper platform is built, bottom segmentation
Normal state is built.As long as in this way, upper platform and bottom segmentation are erected in the same direction, so that it may the two is closed up, without
It needs to turn to upper platform or underlying platform.
Upper platform and bottom segmentation are holded up and be welded together.
Soldered soft cabin 540 is installed to truss 520.
Although specific embodiments of the present invention have been described above, it will be appreciated by those of skill in the art that this is only
For example, protection scope of the present invention is to be defined by the appended claims.Those skilled in the art without departing substantially from
Under the premise of the principle and substance of the present invention, various changes or modifications can be made to these embodiments, but these changes and
Modification each falls within protection scope of the present invention.
