Description
Technical field
The present invention relates to large-scale steel structure welding precision control design, belong to welding technology field.
Background technology
At present; All be difficult the grasp and control during shipyard welding production large-scale steel structure parts at home to the technology of distortion and the large-scale steel structure welding of steel after welding; (hatch board is to cover goods in the cabin such as make Ship Structure and hatch board in welding; Prevent that the seawater infiltration from waiting some external condition factors, protects a kind of structure of goods; Compress and the annex locking mode covers hatch through rubber, install above deck usually), shown in the accompanying drawing in the description of drawings 4, how solving the requirement that after-welding precision reaches regulation is relevant scientific research personnel's problem demanding prompt solution.
Summary of the invention
In order to solve the above problems, the object of the present invention is to provide a kind of large-scale steel structure welding precision control design, it can effectively reduce distortion and error after the welding of large-scale welded steel structure; Its hull adopts segmental structure, and segmental structure is to be split as small-scale structure section one by one to whole Ship Structure by factors such as production capacity and capacities of equipment. treat to carry out closing up after the overall package after the small-scale structure section all completes.
Technical scheme that the present invention takes and structure erection sequence:
1, vertical structure is installed, angle steel (L125X75X8) (16), as shown in Figure 1, can weld.
2, the transversary T0 (1) of the upright part of installation group; T1 (2), T2 (3), T3 (4), T4 (5), T1 ＇ (6), T2 ＇ (7), T3 ＇ (8), T4 ＇ (9); As shown in Figure 2; T0 (1), T1 (2), T2 (3), T3 (4), T4 (5), T1 ＇ (6), T2 ＇ (7), T3 ＇ (8), T4 ＇ (9) are in the welding.
3, vertical structure L6 (10), the L12 (11) of the upright part of installation group are as shown in Figure 3, and L6 (10), L12 (11) are in the welding.
4, the end plate of the upright part of installation group and side plate L1 (12), L18 (13), T5 (15), T5 ＇ (14) are as shown in Figure 4, and L1 (12), L18 (13), T5 (15), T5 ＇ (14) are in the welding.
The principle of the invention and advantage: high-volume formation group is upright to make large-scale steel structure through adding.In the upright making of group, the overhead welding in the proterotype, vertical position welding, horizontal position welding all are converted into downhand welding; Thereby the minimizing cost reduces the welding degree-of-difficulty factor, improves face of weld moulding aesthetics.Primary structural component after in the upright making of group, will welding assembling simultaneously is through shifting to an earlier date the orthopedic sheet material stress that discharges; Thereby bigger distortion can not appear once more in the integral body assembling.Obvious results is out of shape a bigger difficult problem after improving the steel construction moulding like this.

The specific embodiment
To set forth the present invention program's flow process below with the instance of hatchcover peculiar to vessel.
(plane manufacturing) stood by
, group
Little vertical construction is that hatchcover breaks traditions and makes innovation and improve important work progress, is to reduce cost, and shortens the upright cycle of group on the tire, one of the effective behave of enhancing productivity.
Symbol description founds in group: (symbol can independently define)
, panel splicing.Its Type of Welding is CO
2Size Control be theoretical value add offset (
