[0002] According to the requirements of the SOLAS Convention and other conventions and specifications, the bulkheads and decks of ships must meet the corresponding fire resistance requirements. When the hull structure itself cannot meet the fire resistance requirements, it is necessary to lay additional fireproof insulation materials to meet the corresponding fire protection requirements. At present, the installation process of fireproof insulation materials for steel ships is relatively mature. Usually, the rivets are welded to the hull structure first, and then the insulation materials are laid according to the insulation construction requirements.

[0003] In recent years, composite materials have gradually begun to be used in ship hull structures. Due to the particularity of composite materials, welding operations cannot be carried out and the fire resistance of the materials is worse than that of metal materials. The installation process of conventional steel ship fire insulation cannot be implemented on the composite hull structure, and the original construction process cannot meet the fire protection requirements of the composite hull structure.

[0019] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

In addition, the terms "first", "second" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] The invention provides a fireproof insulation structure of a composite material hull.

[0022] Reference Figure 1 to Figure 2b The present invention proposes a first embodiment of a fireproof insulation structure of a composite material hull. In this embodiment, a fireproof insulation structure of a composite material hull includes a hard shell made of composite material and a fireproof insulation cloth located on the outer side of the hard shell (the fireproof insulation cloth can be made of conventional materials in the prior art, and this embodiment is not limited to this). The fireproof insulation cloth penetrates the thickness direction of the hard shell to fix the fireproof insulation cloth on the outer side of the hard shell. When the hard shell is formed by splicing two flat hard shells, the edge of the fireproof insulation cloth on the outer side of the flat hard shell is located on the outer side of the flat hard shell, and the fireproof insulation cloth is extruded at the joint of two adjacent flat hard shells.

[0023] It should be noted that the fireproof insulating cloth extrusion setting means that because the fireproof insulating cloths at the edges of the two flat hard shells protrude outside their edges, when installing the fireproof insulating cloths on the outsides of the two flat hard shells, the flexible fireproof insulating cloths at the edges will be squeezed, thereby ensuring the fireproof insulating performance at the joints of the two adjacent flat hard shells.

[0024] Specifically, the distance between the center of the fastener and the center line of the joint of the fireproof insulating cloth is 40mm~60mm, and the edge of the fireproof insulating cloth protrudes 5mm~15mm outside the edge of the corresponding flat hard shell.

[0025] In this embodiment, the fastener includes a stud, and studs are arranged on both sides of the joint of two adjacent flat hard shells. The distance between the center line of the stud and the joint of the two adjacent flat hard shells is 40mm~60mm ( Figure 2b The setting of 50mm is used as an example for specific explanation).

[0026] The stud includes a stud base and a locking plate sleeved on the stud base. The length of the stud base is 8mm to 12mm longer than the thickness of the fireproof insulation cloth. The stud base can be tightened with two M4×12 mm stainless steel self-tapping screws for auxiliary fixation.

[0027] The fireproof insulation structure of the composite material hull proposed in this embodiment has the following beneficial effects: 1. For the hard shell made of composite materials, fasteners are passed through the hard shell and then the fireproof insulation cloth is fixed, thereby meeting the performance requirements of the composite hull for fireproof insulation; 2. This fireproof insulation structure has the advantages of simple structure, easy implementation and easy operation.

[0028] The present invention also provides a second embodiment of the fireproof insulation structure of the composite material hull. Figure 3a and Figure 3bThe present embodiment is different from the first embodiment in that, for occasions with high requirements for fireproof insulation performance, it is sometimes necessary to set two layers of fireproof insulation cloth. At this time, when the fireproof insulation cloth on the outer side of the flat hard shell includes an inner layer of fireproof insulation cloth and an outer layer of fireproof insulation cloth, the splicing parts of the inner layer of fireproof insulation cloth and the outer layer of fireproof insulation cloth are staggered, and the distance between the center lines of the splicing parts of the inner layer of fireproof insulation cloth and the outer layer of fireproof insulation cloth is less than or equal to 100 mm.

[0029] The present invention also provides a third embodiment of the fireproof insulation structure of the composite material hull. Figure 4a and Figure 4b The difference between this embodiment and the first embodiment is that when the hard shell is composed of two flat hard shells and an insulating sleeve, the bottom of the hard shell of the insulating sleeve is retracted by a height of h, where h is the thickness of the fireproof insulating cloth, and the flat hard shell is retracted by 5mm~15mm relative to the edge of the fireproof insulating cloth outside it.

[0030] The present invention further provides a method for installing a fireproof insulation structure of a composite material hull.

[0031] Reference Figure 5 In this preferred embodiment, a method for installing a fireproof insulation structure based on the above-mentioned composite material hull includes the following steps: Step S30, piercing a plurality of studs on the hard shell according to preset positions, and cutting a plurality of fireproof insulating cloths according to the sizes of all the hard shells; Step S40, attach all the fireproof insulating cloth to one side of the hard shell, the fireproof insulating cloth passes through the nail base of the nail, and then covers the locking sheet on the top to lock the nail and fix the fireproof insulating cloth, the fireproof insulating cloth is extruded at the joint of two adjacent flat hard shells, the joints of the multi-layer fireproof insulating cloth are staggered, and the fireproof insulating cloth is extruded at the joint of the hard shell containing the insulating sleeve; Step S50, performing surface treatment on the outer layer of the fireproof insulation cloth.

[0032] Furthermore, before step S30, the following steps are also included: Step S10, cleaning the surface of the hard shell (acetone may be used to wipe the surface to ensure that the surface is clean and free of foreign matter); Step S20, drawing lines on the hard shell to locate the positions of the studs.

[0033] Specifically, when a plurality of studs are inserted into the hard shell according to preset positions, the stud base is fixed to the marked position of the hard shell using stud glue and checked for debonding.

[0034] Before installing the studs, mix the stud glue according to the stud glue instructions. If the amount is large, use an electric mixer to mix it evenly. If the amount is small, manual mixing is allowed.

[0035] After the installation of the studs is completed, they need to be maintained for 24 hours. After the maintenance period, the installation strength of the studs should be checked. If debonding occurs, they should be removed and re-installed according to the above process.

[0036] Specifically, when the outer layer of the fireproof insulating cloth is subjected to surface treatment, insulating putty, aluminum foil or flame-retardant white cloth is coated on the outer side of the fireproof insulating cloth.

[0037] After the insulation is installed, use insulating putty to level the surface. After the construction is completed, the insulation should be firm, the surface should be flat, and there should be no corner warping. For cabins with interior panels, aluminum foil should be applied to the joints of the insulation material; for cabins without interior panels, a layer of flame-retardant white cloth should be applied to the surface of the insulation material.

[0038] When laying flame retardant white cloth, the cloth should be cut as a whole to minimize the number of seams; the cloth should be laid by brushing flame retardant white glue on one side, and the construction principle of pressing the upper cloth on the lower cloth should be followed. After the construction is completed, the white cloth should not crack or degumming. After the laying of the white cloth is completed, it should be uniformly painted and beautified.

[0039] The installation method of the fireproof insulation structure of the composite hull proposed in the present invention designs a scheme in which the rivets directly penetrate the composite hull according to the material of the composite hull, and then the flexible fireproof insulation cloth is squeezed at the joint to ensure the fireproof insulation performance of the joint. The installation scheme proposed in the present invention is simple and easy to operate on the one hand, and has good fireproof insulation performance on the other hand.

[0040] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
