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

[0033] In the first embodiment, the sealing structure at the junction of the insulating blocks of the B-type containment system of the present invention includes a plurality of first insulating blocks 2 fixed at equal intervals on the cargo hold bulkhead, and the longitudinal section of the first insulating blocks 2 is convex. A first gap 10 for filling the first insulation buffer material 3 is formed between the lower sides of two adjacent first insulation blocks 2. The width of the first gap 10 is 20mm-40mm, and the first gap can be set It is ensured that when the bulkhead is deformed, there is sufficient buffer gap between the two opposite insulating blocks without mutual compression. A second gap 11 for arranging the first aluminum foil 4, the second insulating block 7, the second heat insulating buffer material 5 and the sealing elastic material 8 is formed between the upper sides of two adjacent first insulating blocks.

[0034] A strip-shaped guide groove 12 is provided in...

Embodiment 2

[0046] In the second embodiment, the difference between this embodiment and the first embodiment is that the width of the first aluminum foil 4 is larger than the width of the first gap 10 and smaller than the width of the second gap 11. At this time, the guide groove 12 in the center of the first aluminum foil 4 is located in the middle of the first gap 10.

[0047] After the first aluminum foil 4 is fixed, the second insulating block 7 is fixed. The second insulating block 7 has two fixing methods:

[0048] The first fixing method is to glue the lower surface of the second insulating block 7 on the bosses of the left and right first insulating blocks (that is, the lower surface of the second insulating block 7 is connected to the left and right first insulating blocks. There is an adhesive layer between the bosses of the block), so that there is a certain gap between the two sides and the left and right first insulation blocks, and then fill the second insulation between the two ...

Abstract

The invention discloses a sealing structure of a joint of insulating blocks of a B type enclosure system. The sealing structure comprises a plurality of first insulating blocks fixed on the wall of acargo hold; a first gap filled with a first thermal-insulation buffer material is formed between the lower sides of every two adjacent first insulating blocks; and a second gap for arranging a first aluminum foil, a second insulating block, a second thermal-insulation buffer material, and a sealing elastic material is formed between the upper sides of every two adjacent first insulating blocks; the first aluminum foils are arranged on the first thermal-insulation buffer materials; the second insulating blocks are arranged on the first aluminum foils; the space between the second insulating blocks and the first insulating blocks is filled with second thermal-insulation buffer materials; the sealing elastic materials are arranged on the surfaces of the second insulating blocks; and second aluminum foils are arranged on the surfaces of the sealing elastic materials. Therefore, a problem of the sealing failure of the insulating block joint due to the thermal expansion and cold contractionat 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 invention patent application 201810831689.0 on July 26, 2018. [0002] The invention relates to the technical field of ship construction sealing, in particular to a sealing structure at the joint of insulation blocks of a B-type enclosure system. Background technique [0003] The B-type enclosure system ensures the low-temperature performance and sealing performance of the cargo hold by installing an insulating layer. The insulating layer is assembled by customized insulating blocks, and the connection method between the insulating blocks and the sealing method will affect the performance index of the overall insulating layer. In the process of loading and unloading cargo, the temperature of the cargo hold will change to a certain extent, which will cause deformation of the bulkhead, which will cause squeezing and friction between the insulating blocks. The common sealing method of the joints of the insulating block...
