t1, construction mode of the top side cabin section;
t2, hoisting the top side cabin section;
when in use:
the top side cabin is constructed in a segmented mode: the design method aims at the top side cabin which is divided into deck body middle assemblage, outer plate body middle assemblage and inclined plate body middle assemblage for large combination and gathering, the middle assemblages are respectively built on a plane assembly line, and a crane area which is removed to the outside of the plane assembly line is used for large combination and gathering in sections; on the basis of large segment size and heavy weight, a segment tire position area of a large gantry crane in a field is usually selected for folding to ensure that the segments can be smoothly stripped for hoisting, otherwise, only part of structures can be removed from the segment range, or a larger dock gantry crane area in the field is selected for folding, wherein for the gantry crane with two to four hundred tons, three lifting hooks are matched for hoisting operation, the intervals among the lifting hooks are similar, but the maximum hoisting capacity among the lifting hooks of each crane is different; wherein the lifting capacity of the lifting hook three 3 is one hundred twenty tons to one hundred ninety tons;
the hoisting mode of the top side cabin segment is as follows: a. the outer plate is used as a transportation base surface of the assembly, the assembly can be adjusted to a large group of postures only by turning over ninety degrees, the assembly needs to be in a vertical posture finally, the main hook is considered to be suitable for being adjusted to the large group posture through the assembly gravity center, the attachment hanging code is suitable to be selected and installed at the rib of the cargo hold according to the structural style and the assembly size, the first hanging hook 1 and the second hanging hook 2 are arranged, the distance between the first hanging hook and the second hanging hook is generally eight meters to twelve meters, but more than ten meters is often selected based on the length of the segments, so that the hanging point can cover the length direction of the segments as much as. Usually, the stick is removed immediately after the hoisting is finished, otherwise the folding operation between the total assembly stage and the bottom side cabin section is obstructed;
b. the assembly takes the inclined plate as a transportation base surface, the large group of postures can be adjusted only by turning over one hundred eighty degrees, the main hook lifting horse is arranged at the hatch of the cargo hold according to the structural type, and the auxiliary hook lifting horse is arranged on the non-framework surface of the inclined plate;
c. a sectional tire removal hoisting mode: the construction and transportation of the sections are carried out by taking the deck as a base plane, only flat lifting and tire removal are needed, the main hook and the auxiliary hook are used for hoisting the horses repeatedly, and the hoisting horses at the hatch of the middle cargo hold and the hoisting horses at the non-construction surfaces of the inclined plates are avoided, so that excessive welding and dismantling operations caused by the installation of more hoisting horses are avoided;
d. a sectional total assembly hoisting mode: the deck is used as a transportation base surface for the subsection, the subsection can be adjusted to be in an overall group posture only by turning over ninety degrees, the main hook is recycled, the middle cargo hold hatch is hung with a horse, the auxiliary hook is recycled, and the middle sloping plate is not used for constructing a surface hung horse, because the cargo hold hatch is provided with transverse structures such as hatch coamings, upper piers of cargo hold bulkheads and the like, the structures are considered to be possibly positioned in the middle positions of the subsection in the ship length direction in different ring sections, and simultaneously, a lifting hook steel wire rope rotates relative to the structures in the turning over process and possibly causes interference, so that the main hook can avoid the problems by using a lifting hook I1 and a lifting hook; namely, the distance between a first lifting hook 1 and a second lifting hook 2 of the lifting horse at the hatch of the middle cargo hold is generally eight meters to fourteen meters, and the distance between the outermost lifting horses of the lifting horse of the middle sloping plate non-construction surface is generally two meters to eight meters.

a. the problem of sectional tire removal and hoisting is solved: based on the arrangement of the subsection tire-removing lifting hook, the proportion of the load bearing of the auxiliary hook to the weight of the subsection is generally sixty-five percent to seventy-five percent, and according to the range of the weight of the subsection, the load bearing of the auxiliary hook is generally one hundred fifty tons to two hundred thirty tons, so that the weight of part of the subsection is close to the lifting capacity of a three 3 lifting hook of the outfield gantry crane, and the key point is that the weight of a plurality of subsections exceeds the lifting capacity of the three 3 lifting hook of the outfield gantry crane;
b. the conventional solution is that a gantry crane which is still capable of hoisting is arranged at the maximum tonnage for construction, so that more excellent resources are occupied, and the excellent resources can be allocated according to the production quantity and the periodic variation at any time; for the segments which cannot be hoisted, in the planning stage of the ship type construction mode, the length of the ring segment of a part of ship type is reduced, and the top side cabin segments of the part of ship type are removed from the part of structure, which causes the increase of the workload of the dock stage; for the segments which cannot be hoisted, the positions of a main hook and an auxiliary hook are changed, and at least two hoisting horses are respectively added to the main hook and the auxiliary hook on the basis of the distance between the hoisting horses and the distance between the hoisting hooks, so that the tire-removing hoisting can be completed, but the installation and removal work of at least four hoisting horses is added to each segment;
c. the general hoisting design method comprises the following steps: the original horse is fully utilized, and the position of the auxiliary hook horse is optimized. Based on the former horse arrangement that hangs, only reduce the proportion that the auxiliary hook bearing accounted for segmentation weight, can ensure the segmentation and take off child hoist and mount smoothly, the concrete way is: under the premise of keeping the main hook hanger unchanged, the auxiliary hook is selected to be farther away from the gravity center, if the attached hanger on the rib of the cargo hold assembled in the outer plate body is used as the auxiliary hook, the proportion of the load of the auxiliary hook to the weight of the section is reduced to fifty-three percent to sixty-three percent, the load of the auxiliary hook is reduced to one hundred twenty tons to one hundred ninety tons and reduced to about thirty tons to fifty tons according to the weight range of the section, all the sections can be basically ensured to be smoothly stripped, and the lifting capacity of the crane hooks three 3 is one hundred twenty tons to one hundred ninety tons, so that the weight range of the section for stripping and hoisting can be two hundred twenty tons to three hundred thirty tons, and the condition that different sections of different boat types can be smoothly stripped is basically ensured; optimizing the distance between the attached hanging horses on the cargo compartment ribs, and adjusting the distance between the hanging horses in the hanging hooks to be two meters to eight meters according to requirements after the attached hanging horses on the cargo compartment ribs assembled in the outer plate body are used as a third auxiliary hook hanging hook 3, wherein the distance between the original hanging horses is eight meters to twelve meters, so that the distance between the hanging horses in the hanging hooks is selected to be about eight meters; the tonnage of the suspended horses attached to the ribs of the cargo hold is optimized, the suspended horses are generally twenty-ton to thirty-ton suspended horses due to the light weight of the outer plate body, and the suspended horses are optimized to be forty-ton to fifty-ton suspended horses according to the proportion range of the load bearing of the auxiliary hooks to the weight of the subsection; and optimizing the dismantling stage of the hanging horses attached to the ribs of the cargo hold, wherein the dismantling stage of the original hanging horses is dismantling after the assembling and hoisting in the outer plate body are finished, the dismantling stage is optimized to dismantling after demolding, the requirement of demolding and hoisting can be met without remaining the total assembly stage for dismantling, otherwise total assembly interference is caused, and whether design production execution is carried out according to the dismantling stage after optimization or not is judged according to the crane capacity and the segment weight of the actual production construction site.
