Application of expanded perlite to ship deck and deck structure

Abstract

The invention relates to application of expanded perlite to a ship deck and a deck structure. According to the application method, expanded perlite with reasonable formula is developed, the expanded perlite is prepared into cement expanded perlite by setting a reasonable raw material proportion and then conventional cement mortar leveling method is adopted, so that the application of the expanded perlite to the ship deck is smoothly realized. The deck structure comprises a deck layer and a cement expanded perlite layer in sequence from bottom to top, wherein the cement expanded perlite layer is bonded with the deck layer. According to the application, the cement expanded perlite is used for replacing the currently used primary deck coverings, so that the properties of the obtained deck structure can well satisfy the requirements; and the density of the cement expanded perlite is low and the paving thickness is not limited, so that the weight of the deck structure is greatly reduced, the net weight of the ship body is lightened, the local overweight phenomenon is mediated and eliminated and the stability of the ship body structure is improved.

Description

technical field [0001] The invention relates to the application field of expanded perlite, in particular to the application of expanded perlite on ship decks and a deck structure. Background technique [0002] The deck is an important component of the hull. It is a plane structure located above the inner bottom plate in the ship structure. It is used to cover the interior space of the ship and divide it into layers horizontally. The deck is the steel plate on the beam that separates the hull into upper, middle and lower layers. [0003] The deck on the top of the main hull that runs through the full length is called the upper deck, also called the first deck. The following decks are collectively referred to as the lower deck, followed by the second deck, third deck, etc. The deck below the upper deck is called platform deck or platform. The deck that plays a major role in ensuring the strength of the hull is called the strength deck. The strength deck of a ship with a sh...
