Problems solved by technology

However, the installation accuracy has been difficult to meet the actual needs of on-site berth loading, because in the traditional method, the installation accuracy of the curved panel is affected by three factors: the processing accuracy of the curved panel parts, the installation accuracy of the rib plate, and the welding shrinkage of the segment itself, and the accumulated error It often makes the precision of the curved panel to be out of tolerance, and it is difficult to find out after the out of tolerance

Embodiment Construction

[0015] The present invention will be further described in detail below in conjunction with the accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0016] A projection line control curved surface segmented curved panel installation method, specifically comprising:

[0017] Step 1: According to the computerized tire frame diagram, draw the positioning diagram of the curved panel. The value of the edge type of the plate in the positioning diagram is designed according to the bypass data of the computer tire frame. The intermediate jigsaw type value is designed according to the jigsaw projection line value obtained in the computer tire frame. The angle of the side plate rib is designed by converting the angle value into the projected dimension length and height through the design model. All projection line settings should be designed based on the centerline of the segmental manufacturing reference line (half-width direction),...

Abstract

The invention relates to a mounting method of a flitch with a projection line control curved section curved plate, comprising the following steps: 1, drawing a curved plate location map according to a computerization jig frame map; 2, drawing from a component line related by an outer plate and a projection line of a suture at the end part of the outer part, and installing a rib plate; 3, positioning and installing a component according to the projection line of the ground; and 4, carrying out dispersed adhering on the outer plate, and carrying out trimming cutting on margin according to requirement in the dispersed adhering process, so that the dispersedly adhered outer plate can be positioned and installed strictly according to the projection line. According to the invention, a constructor can intuitively find out precision deviation of curved section construction during construction, so as to avoid accumulated error caused by one or multiple procedures.

Description

technical field [0001] The invention belongs to the technical field of shipbuilding, in particular to a method for installing projection line control curved surface segmented curved panels. Background technique [0002] At present, in the segmental manufacturing stage on site, the water segments at the bottom of the bulk carrier are all reversed with inclined side plates as the base surface, resulting in the installation of such segmental curved panels in a loose pasting manner. Due to the large linear curvature of the curved panel, the traditional practice on site is to use the unfolded value from the curved panel to the rib plate for the installation and positioning of the panel. However, the installation accuracy has been difficult to meet the actual needs of on-site berth loading, because in the traditional method, the installation accuracy of the curved panel is affected by three factors: the processing accuracy of the curved panel parts, the installation accuracy of th...
