Description

Technical Field

[0001] This utility model belongs to the field of ship connection structure technology, specifically relating to a PET foam board connection structure. Background Technology

[0002] In recent years, with the popularization of water recreation activities and the rapid development of water tourism, pontoon yachts have gradually gained favor from the market and users due to their flexibility, stability and multi-functionality. Among them, catamaran pontoon yachts, with their unique catamaran structure design, have higher stability and load-bearing capacity and are widely used in private yachts, floating restaurants, floating hotels and other fields.

[0003] However, traditional catamaran pontoon yachts still have some shortcomings in material selection and manufacturing processes. Currently, most catamaran pontoon yachts use traditional materials such as fiberglass, aluminum alloy, or steel for their pontoons and structures. Although these materials have certain strength and corrosion resistance, they have high density, resulting in a large overall weight of the yacht, which increases manufacturing and transportation costs. Moreover, the production and recycling of traditional materials are often accompanied by high energy consumption and environmental pollution problems. For example, the production of fiberglass requires a large amount of chemical raw materials, while the smelting process of aluminum alloy and steel will also produce greenhouse gases and other pollutants.

[0004] To meet market demand for lightweight, environmentally friendly, and low-cost floating platforms, a catamaran pontoon yacht with PET foam board as the main material is needed. However, existing deck-to-pontoon connection methods still have some inadequacies when applied to catamaran pontoon yachts with PET foam board as the main material. For example, traditional mechanical connection methods such as bolt splicing, riveting, and snap-fit ​​connections are reliable, but stress concentration at the connection point can easily lead to cracking of the PET foam board at the connection point after long-term operation. While adhesive connections are suitable for lightweight requirements, their strength and durability may be limited by the surface characteristics of the PET foam board and environmental factors. Utility Model Content

[0005] The purpose of this invention is to provide a PET foam board connection structure to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A PET foam board connection structure, comprising:

[0008] Two sets of connecting modules are located between the deck and the two pontoons, respectively, for connecting the deck and the pontoons. The connecting modules include a first splicing plate, a second splicing plate, and several sets of snap-fit ​​modules.

[0009] The snap-fit ​​module includes two connecting blocks arranged in a mirror-symmetrical manner. Both the deck and the pontoon are provided with through grooves that cooperate with the snap-fit ​​module. Both connecting blocks are located inside the through grooves of the deck and the pontoon. The upper and lower ends of one side of each connecting block are provided with locking blocks. The locking blocks at the upper and lower ends of one side of each connecting block are used to hook the deck and the pontoon, respectively. The first splicing plate and the second splicing plate are interference-fitted between the deck and the pontoon, so that the connecting blocks form a tenon-and-mortise connection between the deck and the pontoon.

[0010] Preferably, the through-slots on the deck and the pontoons are configured as "T"-shaped structures, so that the connecting block is located inside the through-slot, that is, the upper side of the connecting block is lower than or attached to the upper side of the deck, so that there are no protrusions on the upper side of the deck, which facilitates the installation of other parts of the catamaran pontoon yacht.

[0011] Preferably, the connecting block is configured as a "[" or "]" shaped structure to engage with the through slot. The width of the through slot on the deck and the pontoon is greater than the width of the connecting block, so that the connecting block can easily enter the through slot.

[0012] Preferably, one end of the first splicing plate is configured as a triangular structure, and the outer contour formed by splicing the second splicing plate and the first splicing plate coincides with the upper side contour of the pontoon.

[0013] Preferably, the first splicing plate and the second splicing plate are each provided with an insert block on their respective sides that are close to each other. The insert blocks on the first splicing plate and the insert blocks on the second splicing plate are distributed alternately, and the insert blocks on the first splicing plate and the second splicing plate together limit the corresponding connecting block.

[0014] Preferably, each of the two connecting blocks has a mating groove on one side that is close to each other, and the insert block is located inside the corresponding mating groove.

[0015] Preferably, the first splicing plate and the second splicing plate are connected by a number of bolts through a thread to improve the joint strength between the first splicing plate and the second splicing plate.

[0016] Preferably, the bolts and the snap-fit ​​modules are distributed at equal intervals in a cross pattern.

[0018] This utility model addresses the connection between PET material decks and pontoons.

[0026] 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.

[0027] Example:

[0028] Please see Figures 1-6 As shown, a PET foam board connection structure includes:

[0029] Two sets of connecting modules are located between deck 1 and the two pontoons 2, respectively, for connecting deck 1 and pontoons 2. The connecting modules include a first splicing plate 4, a second splicing plate 5 and several sets of snap-fit ​​modules. The several sets of snap-fit ​​modules are distributed in a straight line at equal intervals along the long axis of symmetry of pontoons 2.

[0030] The snap-fit ​​module includes two connecting blocks 3 arranged in a mirror symmetrical manner. Both the deck 1 and the pontoon 2 are provided with through grooves that cooperate with the snap-fit ​​module. Both connecting blocks 3 are located inside the through grooves of the deck 1 and the pontoon 2. The upper and lower ends of one side of the connecting block 3 are provided with locking blocks. The locking blocks at the upper and lower ends of one side of the connecting block 3 are used to hook the deck 1 and the pontoon 2 respectively. The first splicing plate 4 and the second splicing plate 5 are interference-fitted between the deck 1 and the pontoon 2, so that the connecting block 3 forms a tenon and mortise connection between the deck 1 and the pontoon 2.

[0031] The through slots on deck 1 and pontoon 2 are designed with a "T" shape, so that the connecting block 3 is located inside the through slot. That is, the upper side of the connecting block 3 is lower than or attached to the upper side of deck 1, so that there is no protrusion on the upper side of deck 1, which facilitates the installation of other parts of the catamaran pontoon yacht.

[0032] The connecting block 3 is set as a "[" or "]" shaped structure to cooperate with the through groove to achieve engagement. The width of the through groove on the deck 1 and the pontoon 2 is greater than the width of the connecting block 3, so that the connecting block 3 can enter the through groove.

[0033] The above setup enables a multi-point connection structure between the pontoon 2 and the deck 1 by setting multiple connecting blocks 3 between them. At the same time, the first splicing plate 4 and the second splicing plate 5 are inserted into the connection gap between the pontoon 2 and the deck 1, so that the connecting blocks 3 apply a uniform pressure distribution to the contact surface of the pontoon 2 and the deck 1, thereby enhancing the overall stability and load-bearing capacity of the connection. This structure imitates the traditional mortise and tenon connection principle, so that the pontoon 2 and the deck 1 form a firm, tight and balanced connection, effectively improving the strength and reliability of the overall structure of the catamaran pontoon yacht.

[0034] Furthermore, one end of the buoy 2 of the catamaran pontoon yacht has a sharp triangular diversion structure, which is used to reduce the force exerted on the catamaran pontoon yacht when it moves in the water.

[0035] like Figures 1-6 As shown, one end of the first splicing plate 4 is set as a triangular structure to form the same function as the pontoon 2. The outer contour formed by the splicing of the second splicing plate 5 and the first splicing plate 4 coincides with the upper side contour of the pontoon 2.

[0036] Both the first splicing plate 4 and the second splicing plate 5 have inserts 6 on their adjacent sides. The inserts 6 on the first splicing plate 4 and the second splicing plate 5 are staggered. The inserts 6 on the first splicing plate 4 and the second splicing plate 5 together limit the corresponding connecting blocks 3. The inserts 6 on the first splicing plate 4 and the second splicing plate 5 are in contact with each other and are located between the two corresponding connecting blocks 3, applying force to the two connecting blocks 3.

[0037] Both connecting blocks 3 have mating grooves 7 on their sides that are close to each other, and the insert block 6 is located inside the corresponding mating groove 7.

[0038] Furthermore, the insert 6 can be partially chamfered to facilitate its entry into the mating groove 7 and improve the mating strength.

[0039] The above configuration enables the first splicing plate 4 and the second splicing plate 5 to dock with each other, and the two plates drive the inserts 6 on them to be inserted into the corresponding docking slots 7 simultaneously. During this process, the two inserts 6 are close to each other and fit tightly, located between the two connecting blocks 3, applying lateral pressure to them, thereby enhancing the overall stability of the connection structure. This pressure effectively prevents the connecting blocks 3 from loosening under ship operation or external loads, avoiding the phenomenon of them detaching from the deck 1 and the pontoon 2, ensuring the safety and reliability of the entire connection system under complex working conditions, and improving the durability and performance of the catamaran pontoon yacht structure.

[0040] like Figures 1-6 As shown, the first splicing plate 4 and the second splicing plate 5 are connected by several sets of bolts 8 through a thread, which are used to improve the docking strength of the first splicing plate 4 and the second splicing plate 5, provide additional force, and make the docking of the first splicing plate 4 and the second splicing plate 5 more reliable.

[0041] Several sets of bolts 8 and several sets of snap-fit ​​modules are distributed at equal intervals and crosswise, so that the position of the bolts 8 acting on the first splicing plate 4 and the second splicing plate 5 is evenly distributed with the position of the first splicing plate 4 and the second splicing plate 5 acting on several sets of connecting blocks 3, so as to avoid the phenomenon of local stress concentration in the first splicing plate 4 and the second splicing plate 5.

[0042] like Figures 1-6 As shown, a method for connecting a PET foam board connection structure includes the following steps:

[0043] Step 1: Place two connecting blocks 3 from several sets of snap-fit ​​modules inside the through grooves of deck 1 and pontoon 2, and make the connecting blocks 3 hook deck 1 and pontoon 2 together;

[0044] Step 2: Impregnate the upper and lower sides of the first splicing plate 4 and the second splicing plate 5 with glue, and insert them into the deck 1 and the pontoon 2 with an interference fit. The first splicing plate 4, the second splicing plate 5 and all the connecting blocks 3 form a tenon and mortise connection between the deck 1 and the pontoon 2.

[0045] Step 3: When the first splicing plate 4 and the second splicing plate 5 are connected, the inserts 6 on the first splicing plate 4 and the second splicing plate 5 enter the interior of the docking groove 7 of the corresponding connecting block 3, and the inserts 6 limit the connecting block 3;

[0046] Step 4: Install several sets of bolts 8 inside the first splicing plate 4 and the second splicing plate 5 to fix the first splicing plate 4 and the second splicing plate 5, thus completing the installation.

[0047] This utility model addresses the connection between PET material decks and pontoons. It primarily uses mortise and tenon joints of the first splicing plate 4, the second splicing plate 5, and several sets of connecting blocks 3 to effectively transmit and disperse external forces, avoid stress concentration, and supplement with bolt connections and adhesives to provide additional tensile force for fixation and ensure the sealing and integrity of the connection. This composite connection method fully utilizes the structural potential of PET material.

[0048] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
