A method of installing antique rivets

Abstract

The invention discloses a method for installing an antique rivet. The method comprises: determining a bonding area on the outer panel of a ship, pasting a masking tape on the outside of the bonding area; Grind the surface of the connecting slats to St3 level; mix the adhesive according to the predetermined ratio for a predetermined time to achieve a uniform color; use no less than 1kg of glue for each 3m slat, and pack the mixed adhesive Put it into a mounting bag, open the mouth of the bag to a diameter of 1.5cm, and then apply and scrape it onto the surface of the slats; fix it by spot welding; fill the gaps on both sides of the slats and the seams between the slats with polyurethane foaming agent ; Seal the edge with putty; After all the rivet units are installed, derust and paint along with the main hull. It achieves the technical effects of no large-area welding of the outer plate of the hull, no damage to the internal coating, high installation accuracy, reduced corrosion of the hull and repair of paint, reduced labor intensity, improved production efficiency, and shortened the construction period.

Description

technical field [0001] The invention relates to the technical field of mechanical engineering, in particular to a method for installing antique rivets. Background technique [0002] Hull shell plate is the collective name of the outer bottom plate and side plate. The long sides of the steel plates constituting the outer plate are arranged along the length of the ship to form a long longitudinal row, which is called a plate row. The outer plate is subjected to a large force in some special parts, has various openings or is easy to corrode and wear, and needs to be properly strengthened. thick. At present, the installation of antique rivets on the outer plate of the hull is generally a single rivet arranged in parallel up and down along the weld seam of the outer plate of the hull, and the welding installation method is adopted. [0003] However, in the process of realizing the technical solution of the invention in the embodiment of the present application, the inventor of ...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a method for installing antique rivets, which is used to solve the problem that in the prior art, the outer plate of the hull is easily welded in a large area, and the inner coating is easily damaged, resulting in corrosion of the hull and repair of the paint, resulting in time-consuming, laborious, and prolong The technical problems of the construction cycle have achieved the goal of not being welded in large areas on the hull, the internal coating is not damaged, the installation accuracy is high, the corrosion of the hull and the repair of the paint are reduced, the labor intensity is reduced, the production efficiency is improved, and the construction cycle is shortened. technical effect
