Description

Technical Field

[0001] This utility model relates to the field of shipbuilding technology, and in particular to a bamboo deck for ships. Background Technology

[0002] A deck is an important component of a ship's hull. It is a planar structure located above the inner bottom plate, used to enclose the ship's interior space and horizontally divide it into layers. The deck consists of steel plates on the ship's beams, dividing the hull into upper, middle, and lower layers.

[0003] The uppermost deck, running from bow to stern, is called the upper deck. If all openings on this deck are watertight, it is also called the main deck, and in measurement, it is referred to as the tonnage deck. A few ocean-going vessels have an additional upper deck running from bow to stern above the main deck; since its openings cannot be watertight, it is simply called the shelter deck. The decks below the main deck are called the second deck, third deck, and so on, from top to bottom. All decks above the main deck are short sections, conventionally named according to the cabins or their purpose, such as the bridge deck, lifeboat deck, etc. The midship deck panels on wooden deck barges are also called decks, and are generally movable.

[0004] Existing decks are generally made of steel plates or wood plates. However, there are certain requirements for the use of upper decks. If steel plates are used, the weight is too heavy, which affects the load-bearing capacity of the hull and increases the cost. If wooden decks are used, the wood is soft, easily damaged, and prone to absorbing water and swelling, which affects the service life of the deck. Therefore, in order to avoid excessive deck weight, it is an urgent problem to solve the problem of ensuring the structural strength, service life and corrosion resistance of the deck. Summary of the Invention

[0005] The purpose of this utility model is to overcome the above-mentioned shortcomings of the prior art and provide a ship deck with outstanding structural strength, low cost, low resistance to expansion, and long service life.

[0006] The technical solution of this utility model is: a bamboo deck for ships, comprising a bottom bamboo board, a middle core board and a top cover board, wherein the bottom board, the core board and the cover board are interlocked and pressed together as a whole, and the cover board is provided with grooves at equal intervals, and the grooves are provided with several through holes.

[0007] Preferably, the bamboo used is grown at an altitude of 800-1200 meters in black soil or rocky soil, and is over four years old. The density of the bamboo must be 740 kg / m³. Using bamboo under these conditions ensures the hardness and structural strength of the bamboo board after pressing. More preferably, the bamboo is sawn into strips and then carbonized and dried. Selected bamboo strips with the correct density are used to facilitate the overall pressing of the board. During the pressing process, adhesive is applied and hot-pressed. Grooves are provided on the cover plate to prevent slipping, and through holes are placed in the grooves to filter and drain water, preventing water from accumulating and being unable to drain.

[0008] Furthermore, the depth of the groove is 0.2-0.7 times the thickness of the cover plate, and the cross-section of the groove is trapezoidal. Preferably, the depth of the groove is 0.3-0.6 times the thickness of the cover plate; more preferably, the depth of the groove is 0.5 times the thickness of the cover plate. The groove depth within this range can ensure the strength of the connection between the cover plate and the core plate, while also serving as an anti-slip and water-filtering function. If the groove depth is too deep, it will affect the connection strength between the cover plate and the core plate; if the groove depth is too shallow, the water-filtering effect will be poor, and if items are placed on the deck, it will easily clog the through holes and affect drainage.

[0009] Furthermore, the through holes are distributed in a matrix.

[0010] Furthermore, both the base plate and the cover plate are formed by laterally pressing together several bamboo strips. Preferably, both the cover plate and the base plate are formed by stacking and hot-pressing the width surfaces of the bamboo strips to form a board, so that the distribution of the paper fibers in the cover plate and the base plate is parallel; thereby ensuring the structural strength of the deck.

[0011] Furthermore, the core board is formed by longitudinally pressing together several bamboo strips. Preferably, the core board is a board material formed by hot-pressing the narrow sides of bamboo strips together in one step, and the bamboo fibers in the core board and the cover plate or bottom plate are perpendicularly distributed.

[0012] Furthermore, the base plate, core plate, and cover plate are provided with metal tie rods. The installation of metal tie rods helps to improve the structural strength of the plate and prevent the plate from delaminating and loosening due to strong earthquakes.

[0013] Furthermore, the deck thickness is 2-5 cm. Preferably, the deck thickness is 3 or 3.5 cm.

[0014] Furthermore, the deck surface is coated with paint to waterproof it, preventing it from absorbing water, swelling, or corroding due to prolonged contact with water.

[0015] This utility model has the following beneficial effects: the deck is formed by pressing together a cover plate, a bottom plate and a core plate in a cross-distribution manner, which effectively improves the tensile and shear resistance of the deck, while ensuring the structural strength of the deck. The coating of paint on the deck surface ensures the waterproof and corrosion-resistant effect of the deck.

[0016] The detailed structure of this utility model will be further described below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0017] Figure 1 This is a schematic diagram of the structure of this utility model; 1-Base plate, 2-Core plate, 3-Cover plate, 4-Through hole, 5-Groove. Detailed Implementation

[0018] As shown in the attached figure: A bamboo deck for a ship includes a bottom bamboo board 1, a middle core board 2 and a top cover board 3. The bottom board 1, the core board 2 and the cover board 3 are interlocked and pressed together as a whole. The cover board 3 has grooves 5 at equal intervals, and several through holes 4 are provided in the grooves 5.

[0019] Preferably, the bamboo used is grown at an altitude of 800-1200 meters in black soil or rocky soil, and is over four years old. The density of the bamboo must be above 740 kg / m³. Using bamboo under these conditions can ensure the hardness and structural strength of the bamboo board after pressing. More preferably, the bamboo is cut into strips by sawing and carbonizing and drying the bamboo strips. Select bamboo strips that meet the density requirements to facilitate the overall pressing of the board. During the pressing process, glue is applied and hot pressing is performed. The groove 5 on the cover plate 3 is mainly for anti-slip function, and the through hole 4 is set in the groove 5. Together with the groove 5, it serves to filter and drain water, preventing water from accumulating and being unable to drain.

[0020] In this embodiment, the depth of the groove 5 is 0.2-0.7 times the thickness of the cover plate 3, and the cross-section of the groove 5 is trapezoidal. Preferably, the depth of the groove 5 is 0.3-0.6 times the thickness of the cover plate 3; more preferably, in this embodiment, the depth of the groove 5 is 0.5 times the thickness of the cover plate 3. A depth within this range ensures the strength of the connection between the cover plate 3 and the core plate 2, while also providing anti-slip and water-filtering functions. If the groove 5 is too deep, it affects the connection strength between the cover plate 3 and the core plate 2; if the groove 5 is too shallow, the water-filtering effect is poor, and if objects are placed on the deck, it can easily clog the through holes 4, affecting drainage. The through holes 4 are distributed in a matrix.

[0021] In this embodiment, both the base plate 1 and the cover plate 3 are formed by horizontally pressing together several bamboo strips. Preferably, both the cover plate 3 and the base plate 1 are formed by hot-pressing the wide sides of the bamboo strips together, so that the distribution of the paper fibers in the cover plate 3 and the base plate 1 is parallel; thereby ensuring the structural strength of the deck. The core plate 2 is formed by longitudinally pressing together several bamboo strips. Preferably, the core plate 2 is formed by hot-pressing together the narrow sides of the bamboo strips in one step, and the bamboo fibers in the core plate 2 are perpendicular to those in the cover plate 3 or the base plate 1; thereby, the core plate 2 is staggered with the base plate 1 and the cover plate 3, ensuring the structural strength of the deck and improving its load-bearing capacity, compressive strength, and shear strength.

[0022] In this embodiment, metal tie rods are provided inside the base plate 1, core plate 2, and cover plate 3. The metal tie rods improve the structural strength of the plates and prevent them from delaminating and loosening under strong earthquakes. The deck thickness is 2-5 cm. Preferably, in this embodiment, the deck thickness is 3.5 cm; the thickness of the base plate 1 and cover plate 3 is 1.25 cm, and the thickness of the core plate 2 is 1 cm. The deck surface is coated with paint to waterproof it and prevent it from absorbing water and swelling or corroding due to prolonged contact with water. More preferably, to ensure the connection strength between the base plate 1, core plate 2, and cover plate 3, U-shaped nails are provided on the deck to reinforce the connection between them.

[0023] The deck of this utility model is formed by pressing together a cover plate 3, a bottom plate 1, and a core plate 2 in a cross-distributed manner, which effectively improves the tensile and shear resistance of the deck, while ensuring the structural strength of the deck. The coating of paint on the deck surface ensures the waterproof and corrosion-resistant effect of the deck.
