Description

Technical Field

[0001] This utility model relates to the field of ship deck components technology, and in particular to a basalt fiber reinforced lightweight ship deck component. Background Technology

[0002] Deck components refer to the general term for all kinds of parts that make up the deck structure of a ship. Their core functions are to support the deck panels, transfer loads, ensure the strength and rigidity of the deck, and provide a reliable load-bearing foundation for equipment, personnel activities and cargo stacking on the deck. They are a key component of the ship's superstructure.

[0003] In existing technologies, cargo ships are constructed using steel with a high thermal conductivity, including the hull, deck, bulkheads, ceilings, and auxiliary equipment. In the early stages of a fire, the fire spreads primarily through heat convection; as the fire intensifies and the temperature rises rapidly, the heat spreads through heat radiation without any medium or contact. If there are openings or insufficient insulation in the bulkheads, the fire can quickly spread to other compartments, causing incalculable damage to the ship and cargo, as well as casualties. An existing patent (publication number: CN218985980U) discloses a basalt-rock wool composite board for ship superstructures. The core of the composite board is a rock wool board, which has excellent thermal insulation, fire resistance, and sound absorption and insulation properties, while also exhibiting better water repellency and dimensional stability. The reinforcing plates on both sides of the core board provide superior fire resistance and weather resistance. The strength and toughness are increased without compromising fire resistance. The connection method with fasteners enhances the overall stability of the material, making it more suitable for ship superstructure environments.

[0004] To address the aforementioned issues, while existing patents can improve overall functionality through the use of components such as rock wool boards, in practical applications, the neutral silicone sealant is prone to delamination between layers when subjected to impact or fatigue loads due to its overall weight. Furthermore, the sealant itself has inherent limitations in adhesive strength and aging resistance, making it highly susceptible to failure and detachment under marine conditions of prolonged seawater immersion and salt spray corrosion. Utility Model Content

[0005] The purpose of this invention is to provide a basalt fiber reinforced lightweight deck component for ships, which can achieve weight reduction and enhance the structural resistance to deformation. Through a nano-silica modified epoxy adhesive layer, it resists interlayer slippage caused by ship vibration and impact, completely eliminating the risk of delamination and separation. The rigid anchoring of the positioning anchor further improves the stability of the interlayer connection, preventing separation after long-term use and ensuring the long-term reliability of the deck structure. The interlocking splicing structure of the two deck pieces strengthens the overall connection reliability, ensuring a flush and seamless splicing surface, improving the appearance flatness, and preventing dust from entering the gaps, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a basalt fiber reinforced lightweight deck component for ships, including a center plate, a basalt plate sleeved on the outside of the center plate, and a splicing mechanism for securely connecting with the center plate on one side of the basalt plate, and connecting mechanisms for assembling with other decks at the top and bottom of the basalt plate. The splicing mechanism includes a baffle plate, which is fixedly installed at the front end of the rock slab. A docking hole is provided on the outer wall of the center plate at the position corresponding to the baffle plate, and a positioning anchor rod for fixing the center plate and the rock slab extends through the docking hole. A limiting plate for limiting the baffle plate is fixedly installed at the rear end of the rock slab. A locking groove for limiting the center plate is provided between the two limiting plates, and a rubber sealing layer is embedded in the inner wall of the locking groove.

[0007] Preferably, the inner wall of the limiting plate is provided with a first slot, and one side of the outer wall baffle of the rock slab is provided with a second slot, and a dust-blocking plate for preventing dust adsorption and for aesthetic purposes is slidably connected inside the second slot.

[0008] Preferably, a basalt fiber mesh is embedded between the central plate and the rock plate, and the interior of the basalt fiber mesh is embedded with a nano-silica modified epoxy adhesive layer.

[0009] Preferably, the center plate is internally fitted with an I-beam reinforcement to improve the overall strength, and both the top and bottom ends of the center plate are fitted with abutment blocks.

[0010] Preferably, the connecting mechanism includes a bearing block that extends above the rock slab, and the bearing block has an assembly cavity inside to reduce its weight.

[0011] Preferably, a cross-shaped reinforcing member for improving strength and load-bearing capacity is fixedly installed inside the assembly cavity, and heat-insulating filler is inserted into one side of the cross-shaped reinforcing member inside the assembly cavity.

[0012] Preferably, an insertion block is fixedly installed at the top of the bearing block, and positioning rods for enhancing docking stability are fixedly installed at equal intervals at the top of the insertion block.

[0013] Preferably, the top and bottom ends of the I-beam reinforcement are provided with positioning holes corresponding to the positions of the positioning rods, and a tapered rod is fixedly installed at one end of the positioning rod that passes through the positioning hole.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the combination of baffles, positioning anchors, limiting plates, first slots, second slots, and dust baffles, achieves lightweighting and weight reduction while enhancing the structure's resistance to deformation. Furthermore, the nano-silica-modified epoxy adhesive layer resists interlayer slippage caused by ship vibration and impact, completely eliminating the risk of delamination and separation. The rigid anchoring of the positioning anchors further improves the stability of interlayer connections, preventing separation after long-term use and ensuring the long-term reliability of the deck structure. The interlocking splicing structure of the two deck panels strengthens the overall connection reliability, ensuring a flush and seamless splicing surface, improving the appearance's flatness, and preventing dust from entering the gaps.

[0015] 2. This utility model, through the cooperation of a bearing block, assembly cavity, insertion block, positioning rod, positioning hole, and conical rod, enables the bearing block to compress the rubber contact block on both sides of the deck splicing mechanism, thereby supporting the basalt slabs of the two decks. This not only further enhances the sealing tightness of the splice but also blocks the path of moisture intrusion from the outside, preventing corrosion of internal metal components and aging and failure of the adhesive layer, thus improving the weather resistance and service life of the spliced ​​parts. The bearing block has an assembly cavity, which effectively optimizes the overall lightweight effect. The cross-shaped reinforcement inside the cavity can significantly improve its own load-bearing and compressive strength, preventing damage and deformation of the support parts due to concentrated stress. When the bearing block and the contact block are in contact, the insertion block simultaneously presses against the I-beam reinforcement, and the positioning rod of the conical structure is inserted into the positioning hole, greatly improving the stability and load-bearing capacity of the bearing block for the deck, which can fully cope with complex conditions such as turbulence and impact during ship navigation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides a technical solution: Please see Figures 1 to 4 A lightweight basalt fiber reinforced ship deck component includes a center plate 1, a basalt fiber plate 2 sleeved on the outside of the center plate 1, a splicing mechanism 3 for secure connection with the center plate 1 on one side of the basalt fiber plate 2, and connection mechanisms 6 for splicing with other decks at the top and bottom of the basalt fiber plate 2. The splicing mechanism 3 includes a baffle 301 fixedly installed at the front end of the basalt fiber plate 2. A mating hole 302 is opened on the outer wall of the center plate 1 at the position corresponding to the baffle 301. A positioning anchor 303 for fixing the center plate 1 and the basalt fiber plate 2 passes through the mating hole 302. A limiting plate 304 for limiting the baffle 301 is fixedly installed at the rear end of the basalt fiber plate 2. The two limiting plates... A locking groove 305 for limiting the center plate 1 is provided between 304. The inner wall of the locking groove 305 is fitted with a rubber sealing layer 306. The inner wall of the limiting plate 304 is provided with a first locking groove 307. A second locking groove 308 is provided on one side of the outer wall baffle 301 of the rock slab 2. A dust baffle 309 for preventing dust adsorption and for aesthetic purposes is slidably connected inside the second locking groove 308. A basalt fiber mesh 310 is embedded between the center plate 1 and the rock slab 2. A nano-silica modified epoxy adhesive layer 311 is embedded inside the basalt fiber mesh 310. An I-beam reinforcement 4 for improving the overall strength is embedded inside the center plate 1. Abutment blocks 5 are embedded at the top and bottom of the center plate 1.

[0021] By adopting the above technical solution, the center plate 1 uses a vertical fiber structure rock wool composite board. Utilizing the directional arrangement of vertical fibers, it achieves lightweight reduction while simultaneously providing thermal insulation, heat preservation, and fire resistance, effectively enhancing the structure's resistance to deformation. A basalt fiber mesh 310 is embedded between the center plate 1 and the basalt plate 2, and bonded and filled using a nano-silica modified epoxy adhesive layer 311. The three-dimensional mesh structure of the fiber mesh and the adhesive layer form a mechanical interlock, while the active groups of nano-silica form stable chemical bonds with the surface molecules of both types of boards, fundamentally resisting interlayer slippage caused by ship vibration and impact, completely solving the hidden dangers of delamination and separation. A butt joint hole 302 is opened at the corresponding position of the baffle 301 and the center plate 1, and a positioning anchor rod 303 is inserted to form a rigid anchoring connection, further improving the stability of the interlayer connection and avoiding interlayer separation problems after long-term use. When the two decks are spliced... A set of baffles 301 are embedded in the locking grooves 305 of another set of limiting plates 304 to form an interlocking splicing structure, which strengthens the overall connection reliability. The matching rubber sealing layer 306 can achieve full sealing protection of the splicing seam, preventing seawater and water vapor from entering the internal components and avoiding metal corrosion and adhesive failure. At the same time, the second locking groove 308 of the basalt plate 2 and the first locking groove 307 of the limiting plate 304 are used to slide and lock the dust baffle 309, which can not only ensure that the splicing surface is flat and seamless, improving the flatness of the deck appearance and the comfort of walking, but also prevent dust from entering the gaps, reducing the frequency and difficulty of later cleaning and maintenance. In addition, multiple sets of carbon fiber reinforced composite hollow I-beam reinforcements 4 are equidistantly embedded inside the center plate 1. The hollow structure further reduces the self-weight, while the I-beam section significantly improves the deck's bending and shear strength, achieving a two-way balance between lightweight and high structural strength, and meeting the dual requirements of ship decks for load-bearing capacity and lightweight.

[0022] Specifically, such as Figure 1 , Figure 3 and Figure 5 As shown, the connecting mechanism 6 includes a bearing block 601, which protrudes above the rock slab 2. The bearing block 601 has an assembly cavity 602 inside to reduce its own weight. A cross-shaped reinforcing member 603 for improving strength and load-bearing capacity is fixedly installed inside the assembly cavity 602. A heat insulation filler 604 is inserted into one side of the cross-shaped reinforcing member 603 inside the assembly cavity 602. An insertion block 605 is fixedly installed at the top of the bearing block 601. A positioning rod 606 for strengthening the docking stability is fixedly installed at an equal distance on the top of the insertion block 605. Positioning holes 607 are opened at the top and bottom of the I-beam reinforcing member 4 corresponding to the positions of the positioning rod 606. A tapered rod 608 is fixedly installed at one end of the positioning rod 606 that passes through the positioning hole 607.

[0023] By adopting the above technical solution, on the other two sides of the two deck splicing mechanism 3, a load-bearing block 601 made of carbon fiber reinforced composite material is assembled. It supports the basalt plate 2 of the two decks by squeezing the rubber abutment block 5, which not only further enhances the sealing tightness of the splice, but also blocks the path of water vapor intrusion. The load-bearing block 601 has an assembly cavity 602 to optimize the lightweight effect. The cross reinforcement 603 set in the cavity can significantly improve its own load-bearing and compressive strength. At the same time, it is filled with heat insulation filler 604, which forms a heat insulation linkage with the rock wool composite board of the center plate 1 to ensure the consistency of the overall heat insulation effect of the deck. When the load-bearing block 601 is attached to the abutment block 5, the insertion block 605 simultaneously abuts the I-beam reinforcement 4, and the conical positioning rod 606 is inserted into the positioning hole 607. With the help of the positioning and self-locking of the conical rod 608, the support stability and load-bearing capacity of the load-bearing block 601 on the deck are improved, realizing the integrated reinforcement of sealing, support and positioning of the splice part.

[0024] Working principle: The center plate 1 uses a rock wool composite board with a vertical filament structure, which has the functions of heat insulation, thermal insulation and fire resistance. It can achieve weight reduction while ensuring the structural insulation and deformation resistance. Basalt fiber mesh 310 is embedded between the center plate 1 and the basalt plate 2, and a dual connection structure of mechanical interlocking and chemical bonding is constructed through a nano-silica modified epoxy adhesive layer 311. This can initially resist the problem of delamination or separation caused by interlayer slippage due to ship vibration and impact. A baffle 301 of the same material is fixed on one side of the basalt plate 2, and the baffle 301 and the corresponding center plate 1 are provided with docking holes 302. The positioning anchor rod 303 is inserted and fixed, which can further improve the docking stability and prevent interlayer separation after long-term use. When splicing the two decks, A set of baffles 301 are inserted into the engagement grooves 305 of another set of limiting plates 304 to form an interlocking structure, which strengthens the connection reliability between the center plate 1 and the basalt plate 2. The rubber sealing layer 306 can improve the sealing of the deck splice and prevent external moisture from entering and causing corrosion of internal components. In addition, by using the second groove 308 of the basalt plate 2 and the first groove 307 of the limiting plate 304, the dust baffle 309 is slidably engaged, which can not only ensure that the splice surfaces of the two decks are flush and eliminate gaps, improving the appearance flatness, but also prevent dust from entering the gaps and reduce the difficulty of later maintenance. Multiple sets of hollow I-beam reinforcements 4 are equidistantly embedded inside the center plate 1. The reinforcements are made of carbon fiber reinforced composite material, which significantly improves the overall structural strength of the deck while maintaining lightweight. On the other two sides of the two deck splicing mechanism 3, there are load-bearing blocks 601 made of carbon fiber reinforced composite material. These blocks support the basalt plates 2 of the two decks by extruding rubber contact blocks 5, further enhancing the sealing of the splice and blocking the path of water vapor intrusion. The load-bearing block 601 has an assembly cavity 602 to optimize the lightweight effect. The cavity is equipped with a cross-shaped reinforcing member 603 to improve the load-bearing and compressive strength performance. At the same time, it is filled with heat insulation filler 604 to ensure the overall heat insulation effect of the deck. When the load-bearing block 601 is in contact with the contact block 5, the insertion block 605 presses against the I-beam reinforcing member 4. The tapered positioning rod 606 is inserted into the positioning hole 607. With the help of the self-positioning characteristics of the tapered rod 608, the support stability and load-bearing capacity of the load-bearing block 601 for the deck are greatly improved. Ultimately, this ensures the deck is securely joined and prevents it from loosening, while also achieving a significant weight reduction effect.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
