Floating Floor
Ship products commonly used insulation material is rock wool, has excellent fire prevention, heat preservation and acoustic performance, so the floating floor of the ship can be rock wool as part of its bottom layer. In order to improve the function of the floating floor, a layer of damping can be laid on top of the rock wool. The combination of rock wool and damping can maximize the effect of vibration and noise damping, which is also a trial. The outfittings in the cabin are mostly metal, so to facilitate welding of the floor and outfittings, the top layer of the floating floor should be constructed of steel plates.
Overview
Process Requirements:
1. To prevent bending of the rock wool, remove all debris from the steel deck before laying rock wool directly on the steel deck.
2. Lay the rock wool (50 mm thick) close together without gaps between the rock wool. At the same time, lay the rock wool in staggered seams so that the seams do not run in a line (
3. Lay steel strips on top of the rock wool, with specifications of 140mm x 2000mm x 1.5mm.
4. lay steel plate (specification 1000mm×2000mm×2mm, electro-galvanized) on the steel strip, each corner of the steel plate at a distance of 5cm and the edge of the ring steel plate every 25cm are spot welded, and before laying the next layer of the spot welding position must be polished.
5. Pre-measure and pre-cut the 3mm steel sheets before applying the Sika Damping, and then remove the cut sheets.
6. Apply Sika Damping with a sawtooth trowel to a thickness of 1.5 mm, the area of Sika Damping to be applied being slightly larger than the area of the steel plate to be laid at any one time.
7. Press a 3mm steel plate (1000mm x 2000mm x 3mm, electro-galvanized) directly onto the wet Sika Damping layer.
8. Floating floors are to be laid at a distance of 10mm from bulkheads, hull structures, through-hull members, etc. and the edges sealed with Sika damping.
