Description

Construction method of ship side cabin section

Technical Field

The invention relates to the technical field of ship manufacturing, in particular to a method for constructing a ship side cabin section.

Background

In the shipbuilding industry, due to the huge body shape of a ship, in the actual ship building process, the ship is generally manufactured by dividing the ship into sections one by one, and in order to improve the building efficiency in the sections, the ship is generally built by dividing the ship into a plurality of smaller sub-sections according to specific structural forms.

The ship side cabin segment refers to an upper side cabin segment and a lower side cabin segment, wherein the upper side cabin segment comprises a slope plate sub-segment, a deck plate sub-segment and an outer plate sub-segment, and the lower side cabin segment does not comprise the deck plate sub-segment and only comprises the slope plate sub-segment and the outer plate sub-segment. The construction methods of the upper side cabin section and the lower side cabin section are the same except that the construction of the deck sheet body sub-section is not performed.

When building boats and ships side tank segmentation, slope board segmentation needs to transport, the process that will slope board segmentation break away from it on the support mould when the preparation is called down child in the transportation, need to carry out the operation of standing up when transporting to next station, need arrange two sets of lugs when down child and the operation of standing up, down child lug just need excision with once only, and the welding that produces in the middle, various expenses such as flaw detection, polishing all lead to material and cost of labor increase, and current stand up lug also has certain problem, can block when main hook lug and planking lamellar body segmentation are combined, influence the assembly, need cut the lug head, and the secondary hook lug design is the purpose-made lug that is connected with the longitudinal bone, the welding quantity is big, demolish troublesome after the use. After searching, no existing method for constructing the ship side cabin section similar to the method is found, the invention patent with the application number of CN201210354081.6 and the name of detachable lifting lug structure for ship T-section sectional hanging is described as a tool for clamping the T-beam panel, and the tool can be repeatedly used, but has certain defects, namely, only small tonnage can be used, and the T-beam panel is seriously plastically deformed due to overlarge bearing; secondly, the installation and dismantlement process are difficult, and the frock needs to penetrate from the one end of structure T roof beam, removes certain distance through sliding friction, and difficult operation, and in case there is additional strengthening on the T roof beam, the frock just can 'T advance, and is very limited very easily can' T use.
