Description
Technical field
The invention belongs to shipbuilding technical field, more particularly to a kind of method of construction of width type segmentation.
Background technology
Width type is segmented the bottom section for referring to ship bow stern, at the bow stern both ends of ship, the change width of ship
It is obvious, and width type segmentation in, port and starboard be in same segmentation, the installation of floor and stringers is more
Closely, welding density is larger, and the stressing conditions of segmentation are complicated, because the outside plate line style of width type segmentation is larger, is needed in welding
Use CO2Carry out manual welding, more than reason cause welding after width type be segmented deformation it is larger, bottom plate and outside plate easily generate
Larger accuracy error, the both ends of bottom plate and the both sides of outside plate easily upwarp, and cause in the subsequent ship closure stage
It is difficult to close up assembling, as shown in Figure 1, solid line a is the width type segmentation vertical section exterior contour in design in Fig. 1, in Fig. 1
Dotted line b is to be segmented vertical section exterior contour using width type during conventional construction method.In order to which be smoothed out ship closes up assembling,
It needs to repair width type segmentation, expends the more time, seriously affected the progress of shipbuilding, therefore width type point
The construction one of section is directly subordinate to an important difficult point during shipbuilding.
Invention content
For the deficiencies in the prior art, the present invention proposes a kind of method of construction of width type segmentation, for solving
The problem of certainly existing width type segmentation is difficult to build.
A kind of method of construction of width type segmentation, includes the following steps：

Lateral topside is gradually installed, and is carried out tack welding between the second outside plate jigsaw and middle stringers, is carried out between the second outside plate jigsaw
Tack welding forms the second outside plate, and tack welding is carried out between the second outside plate jigsaw and the second floor, to the second outside plate jigsaw and the
Tack welding is carried out between two side stringers, forms the second segmentation；
Step 4: the levelness of the first bottom plate and the second bottom plate is examined, if the levelness deviation at four angles of the first bottom plate is more than 10
Millimeter, then the levelness of the first bottom plate is unqualified, needs to repair the first bottom plate, if the levelness at first four angles of bottom plate
Deviation is no more than 10 millimeters, then the levelness of the first bottom plate is qualified, the levelness of the second bottom plate is examined, if four angles of the second bottom plate
Levelness deviation more than 10 millimeters, then the levelness of the second bottom plate is unqualified, needs to repair the second bottom plate, if second
The levelness deviation at four angles of bottom plate is no more than 10 millimeters, then the levelness of the second bottom plate is qualified；
Step 5: to first segmentation in fillet weld in the flat position and fillet weld in the vertical position freeze, to second segmentation in fillet weld in the flat position and
Fillet weld in the vertical position freezes；
Step 6: the first segmentation and the second segmentation are closed up, the weld seam between the first bottom plate and the second bottom plate is burnt
Weldering, the weld seam between the first floor and the second bottom plate is freezed, the weld seam between the first floor and middle stringers is burnt
Weldering, the weld seam between the first floor and the second outside plate is freezed, and the weld seam between the first outside plate and the second outside plate is carried out
It freezes, forms width type segmentation；
Step 7 by width type sectional turn-over 180 degree, freezes to the fillet weld in the flat position after turn in width type segmentation, overall with
Type sectional construction finishes.
Preferably, in the step 3, the width type for being in ship fore body is segmented, first floor is in ship bow
The erection sequence in stern direction is installed successively from the stern direction of ship to the fore body direction of ship, and the first outside plate jigsaw exists
The erection sequence in ship bow stern direction is installed successively from the stern direction of ship to the fore body direction of ship, second floor
Erection sequence in ship bow stern direction is installed successively from the stern direction of ship to the fore body direction of ship, outside described second
Erection sequence of the plate jigsaw in ship bow stern direction is installed successively from the stern direction of ship to the fore body direction of ship, for
Width type segmentation in ship stern, erection sequence of first floor in ship bow stern direction is from the fore body side of ship
It is installed successively to the stern direction of ship, erection sequence of the first outside plate jigsaw in ship bow stern direction is from ship
Fore body direction is installed successively to the stern direction of ship, and erection sequence of second floor in ship bow stern direction is from ship
Fore body direction installed successively to the stern direction of ship, erection sequence of the second outside plate jigsaw in ship bow stern direction is
