Description
Technical Field
The invention relates to the field of shipbuilding, in particular to an A60 fireproof insulation protection method for the reverse roof of an engine room.
Background
At present, the main deck and the engine room are built on most cargo ships, the separation between the main deck and the engine room of the engine room is A60 grade, and in order to reach the protection requirement of A60, an A60 deck dressing is generally laid on the deck surface, but the following problems exist in laying the dressing:
1) the a60 dressing is relatively heavy and increases the weight of the empty boat, thereby reducing the load on the boat.
2) According to the solas specification, a 450mm extension of the dressing is required, resulting in increased labor and an unsightly extension for those areas without a trim panel.
3) Because the order problem of carrying, the dressing can influence the construction progress, reduces work efficiency.
4) The addition of dressing in the launder required modification of the standard R orifice and therefore often required the addition of a specific orifice (R35 instead of H80R 25)
5) The space is reduced, and the extension on the general deck face is 40mm, leads to some places unable construction, like the decorative board.
6) The deck covering increases the height of the water fall of the deck, typically by 50 mm.

s3: passing the A60 fire-resistant material through the pegs and installing;
s4: the a60 fire-resistant material was secured with caps and gaskets.
Preferably, the A60 fireproof insulation protection method for the nacelle roof further comprises the following steps:
s5: bulkhead and buttress extensions exceeding 450mm are made a 60.
Preferably, the A60 fireproof insulation protection method for the nacelle roof further comprises the following steps:
s6: and local repair is carried out.
Preferably, in step S6, an aluminum foil tape is attached at the seam.
Preferably, in step S2, the stud is fixed to the deck plate or the buttress material by a butt-welding machine.

The positive progress effects of the invention are as follows: the method uses A60 fireproof material to replace A60 deck dressing, greatly reduces the total weight of the ship body, and is beautiful and low in cost.
Drawings
Fig. 1 is a schematic flow chart of an a60 fire-proof insulation protection method for a nacelle roof according to a preferred embodiment of the invention.
Detailed Description
The present invention is further illustrated by way of example and not by way of limitation in the scope of the following examples in connection with the accompanying drawings.
As shown in fig. 1, the a60 fire-proof insulation protection method for the reverse roof of the cabin comprises the following steps:
step 100: providing a planar A60 fire-resistant material;
step 200: fixing the touch nails on a deck surface or a wall supporting material;
step 300: passing the A60 fire-resistant material through the pegs and installing;
step 400: the a60 fire-resistant material was secured with caps and gaskets.
The A60 fireproof insulation protection method for the reverse roof of the cabin further comprises the following steps:
step 500: bulkhead and buttress extensions exceeding 450mm are made a 60.
The A60 fireproof insulation protection method for the reverse roof of the cabin further comprises the following steps:
step 600: and local repair is carried out.
In step 600, aluminum foil tape is applied to the seams.
In step 200, a touch pin is secured to the deck or buttress material using a touch-weld machine.
Preferably, the A60 fireproof material is rock wool or ceramic fiber wool.
Preferably, the density of the A60 fireproof material is 170kg/m3。
Preferably, the thickness of the A60 fireproof material is 40-60 mm.
The adoption of the A60 fireproof insulation protection method of the reverse top of the deck can be beneficial to:
a great weight saving, according to A60 the density of the deck covering is generally 1500kg/m3While the density of the A60 insulating material for the deck reverse top is 170kg/m3Thus, for the current standard, it is up to about 560m2With a 50mm thickness of deck covering according to a60 and a 30mm fire-resistant insulation, the weight that can be reduced is: 560 ≈ 0.050 ≈ 1500-0.030 ≈ 170 ≈ 39000kg ═ 39 tons.
The A60 is installed on the back surface of the deck in an insulating way, so that the deck surface does not need to be extended, and no extending part exists, so that the room is tidier and more attractive.
Because A60 insulation installation is in the anti-top of cabin, main deck face need not to do dressing etc. can be under construction in advance other processes, improves work efficiency.
Can reduce procurement cost, and the price of A60 deck dressing is 125 yuan/m calculated by a standard upper building of about 560 squares according to the previous price2The price of A60 insulating material is 35 yuan/m2The cost can be saved: 560 x (125-35) ≈ 5 ten thousand yuan.
The size of the water flowing holes on the wall supporting material can be reduced.
The height of the water leakage port is reduced by about 30-40 mm.
