Embodiment

[0038] A kind of skeleton connection method of polyethylene (PE) fishing boat, the steps are as follows:

[0039] Step one, right Image 6 Among the four types of components (keel 1, side girder 2, hatch coaming bottom plate 3, floor plate 4) that constitute the frame of this type of fishing boat involve staggered and connected positions, and positioning gaps are processed respectively; among them:

[0040] a) The keel 1 and the side girder 2 are longitudinal members, and the joints with the floors 4 are of equal height, and the gaps face inward;

[0041] b) The height of the bottom plate 3 of the hatch coaming is greater than the height of the floor plate 4 at the joint, then according to Figure 4 , to determine the gap orientation;

[0042] c) The notch orientation of floor plate 4 is determined after the notch orientation of keel 1, side girder 2 and hatch coaming floor 3 are determined;

[0043] d) Calculate the various geometric parameters of the gap according to the ...

Abstract

The invention provides a skeleton connecting method of a thermoplastic polymer ship, and belongs to the technical field of ship construction. Basic parts adopted in the connecting method are assemblies forming the thermoplastic polymer ship skeleton in the transverse direction, the longitudinal direction and the vertical direction, are called as components, and comprises a longitudinal component,a transverse component and a vertical component; plug-in type connection and welding are conducted through prefabricated positioning notches with specific intervals in the components, and it is guaranteed that the components in the transverse direction, the longitudinal direction and the vertical direction are always continuous in the component direction. Compared with a traditional ship skeletonwelding method, the construction precision is greatly improved, and the construction difficulty and cost are reduced; the prepared thermoplastic polymer ship skeleton has more excellent structural stability, strength and impact resistance, and the safety of the whole ship is improved.

Description

technical field [0001] The invention relates to a skeleton connection method of a thermoplastic polymer ship, which belongs to the technical field of ship building. Background technique [0002] In the traditional shipbuilding process, the segmental welding method is usually used to connect the hull skeleton, that is, the components are disconnected at the staggered joints and then welded. For ships made of metal, this method is mature and has no obvious disadvantages. However, for thermoplastic polymer ships, due to their material characteristics, the strength of the welding part is weaker than that of the material body, and the welding part will become the weak point of the entire skeleton structure; , each welding will deform the structure, and as the welding continues, the deformation will continue to accumulate, and the overall dimensional deviation of the skeleton will easily occur; moreover, steel ships use spot welding to pre-position components. Also due to the cha...
