Problems solved by technology

During the loading and unloading process of the cargo hold, the temperature will change to a certain extent, which will cause the deformation of the bulkhead and cause extrusion and friction between the insulating blocks. The ordinary sealing method of the insulating block connection may not be able to cope with this situation. Lead to tightness failure at the junction of insulating blocks

Embodiment 1

[0049] Embodiment 1, the method of the present invention for sealing the connection of insulating blocks of a B-type containment system specifically includes the following steps:

[0050] Step 1: Use bolts to fix multiple first insulating blocks 2 with a convex longitudinal section at the target position at the bottom of the cargo hold (cargo hold bulkhead 1), so that a 20mm gap is formed between the lower sides of two adjacent first insulating blocks 2 A first gap 10 of 40 mm, and a gap between the upper sides of two adjacent first insulating blocks is a second gap 11 .

[0051] Setting the first gap between two adjacent first insulating blocks 2 can ensure that there is a sufficient buffer gap between the two opposing insulating blocks when the bulkhead deforms without mutual extrusion.

[0052] When installing the first insulating block 2, it should be ensured that the deviation between the installation position and level of the first insulating block 2 and the theoretical ...

Embodiment 2

[0061] Embodiment 2. The difference between this embodiment and Embodiment 1 is that the width of the first aluminum foil 4 fixed in step 3 is larger than the width of the first gap 10 and smaller than the width of the second gap 11 . At this time, when fixing the first aluminum foil 4 , the diversion groove 12 in the center of the first aluminum foil 4 should be located in the middle of the first cavity 10 . After the first aluminum foil 4 is fixed, the second insulating block 7 is fixed.

[0062] The second insulating block 7 has two fixing methods:

[0063] The first fixing method is to bond the lower surface of the second insulating block 7 on the bosses of the left and right first insulating blocks, so that the two side surfaces and the left and right first insulating blocks are left. There is a certain gap, and then the second thermal insulation buffer material 5 is filled respectively between these two gaps.

[0064] The second fixing method is to bond the left side a...

Embodiment 3

[0066] Embodiment 3, the method for sealing the connection of insulating blocks of the B-type containment system of the present invention specifically includes the following steps:

[0067] Step 1: Fix a plurality of first insulating blocks 2 with a convex longitudinal section at the target position on the top of the cargo hold, so that a first gap 10 of 20mm-40mm is formed between the lower sides of two adjacent first insulating blocks. The gap between the upper sides of two adjacent first insulating blocks is the second gap 11 .

[0068] Step 2: filling the first gap 10 with the first thermal insulation buffer material 3 .

[0069] Step 3: Place the second insulating block 7 on the first thermal insulation buffer material 3 , the width of the second insulating block 7 is larger than the width of the first gap 10 and smaller than the width of the second gap 11 .

[0070] Step 4: Fix the second insulating block 7 and the first insulating block 2 through the adhesive 6, and le...

Abstract

The invention discloses a method for sealing the joint of insulating blocks of a B type enclosure system. The method comprises the following steps: installing a plurality of first insulating blocks attarget positions of a cargo bulkhead; filling a gap between every two adjacent first insulating blocks with a first thermal-insulation buffer material; covering the first thermal-insulation buffer materials with first aluminum foils; placing second insulating blocks on the first aluminum foils and fixing the second insulating blocks with the first insulating blocks; filling gaps among the secondinsulating blocks and the first insulating blocks with second thermal-insulation buffer materials; fixing sealing elastic materials on the surfaces of the second insulating blocks; and pasting secondaluminum foils on the sealing elastic materials. The method is operated simply and installation becomes convenient. A problem of the sealing failure of the insulating block joint due to the thermal expansion and cold contraction at the independent cabin wall is solved effectively; and the extrusion between the insulating blocks is prevented and the sealing performance of the joint is not damaged.

Description

technical field [0001] This patent is a divisional application of the invention patent application 201810831688.6 on July 26, 2018. [0002] The invention relates to the technical field of ship building sealing, in particular to a method for sealing the connection of insulating blocks of a B-type containment system. Background technique [0003] The Type B containment system ensures the low temperature performance and sealing performance of the cargo compartment by installing an insulating layer. The insulating layer is assembled from custom-made insulating blocks, and the connection method and sealing method between the insulating blocks will affect the performance index of the overall insulating layer. During the process of loading and unloading cargo, the temperature of the cargo compartment will change to a certain extent, which will cause the deformation of the bulkhead, which will cause extrusion and friction between the insulating blocks. Lead to the failure of the ...
