Description

A lightweight, high-strength, multi-purpose bamboo laminated container and its manufacturing method Technical Field

[0001] This invention relates to a lightweight, high-strength, multi-purpose bamboo laminated container and its manufacturing method, belonging to the field of cargo transportation. Background Technology

[0002] Steel containers have a relatively large tare weight. Taking a common 20-foot standard steel container as an example, its own weight can reach about 2.3 tons. The large tare weight leads to a reduction in effective cargo capacity and an increase in fuel consumption.

[0003] Steel is prone to corrosion and requires regular maintenance. The steel production process consumes large amounts of resources such as iron ore and coal, and also generates large amounts of pollutants such as carbon dioxide and waste residue.

[0004] Using lightweight materials such as aluminum alloys would be costly and have limitations in terms of strength and impact resistance, making it difficult to fully meet the requirements of the complex operating environment of containers. Summary of the Invention

[0005] To address the aforementioned problems, the primary objective of this invention is to propose a lightweight, high-strength, multi-purpose bamboo laminated timber container that is lightweight, high-strength, possesses excellent mechanical properties, a robust structural system, low cost, and is easy to assemble and manufacture.

[0006] The second objective of this invention is to provide a method for manufacturing a lightweight, high-strength, multi-purpose bamboo laminated container.

[0024] Furthermore, the cargo entry / exit gate can be located in one, two, or three positions: the top, the side, or the end face.

[0025] Furthermore, the lightweight, high-strength, multi-purpose bamboo laminated timber container can be used as a house.

[0026] Based on the same inventive concept, this invention also discloses a method for manufacturing a lightweight, high-strength, multi-purpose bamboo laminated timber container, comprising the following steps:

[0027] Step 1: Prepare an integrated corner fitting-fiberglass-steel plate-steel sleeve-bolt connector with end holes, side holes, top holes, or bottom holes. This integrated corner fitting-fiberglass-steel plate-steel sleeve-bolt connector can be used to connect beam structural members, column structural members, and for lifting bamboo-laminated containers. The steel sleeve portion and bolt assembly of the integrated corner fitting-fiberglass-steel plate-steel sleeve-bolt connector are used for end connections of column structural members, and the centroids of the steel sleeve and the corner fitting are on a straight line, or the horizontal projection distance between the two centroids is less than one-fifth of the shorter side length of the steel sleeve. The steel plate of the integrated glass fiber-steel plate-steel sleeve-bolt connector is in the shape of a straight line or an I-beam. The steel plate and bolt are combined to connect the end of the beam structure. A glass fiber-steel transverse short beam is prepared. The two ends of the glass fiber-steel transverse short beam are set as "door" shaped structures that can be used to fix bamboo laminated timber containers or to allow forklifts to load and unload bamboo laminated timber containers from the end face. A glass fiber-steel composite cylinder for forklifts is prepared. The glass fiber-steel composite cylinder for forklifts has square or round holes with a spacing of not less than 40 mm and a spacing of not less than 80 mm on both sides, or no holes are opened.

[0028] Step 2: Prepare the bamboo engineered wood longitudinal edge beams, bamboo engineered wood or glass fiber-steel transverse short beams, bamboo engineered wood or glass fiber-steel longitudinal middle beams, bamboo engineered wood corner posts, bamboo engineered wood edge posts, bamboo engineered wood diagonal braces, top bamboo engineered wood panels, first side bamboo engineered wood panels, and second side bamboo engineered wood panels.

[0029] Step 3: Build a "mu" - shaped bottom fiberglass - steel - bamboo laminated timber frame structure composed of 2 fiberglass - steel composite cylinders for forklifts, longitudinal bamboo laminated timber side beams, and 2 fiberglass - steel transverse short beams; the 2 fiberglass - steel composite cylinders for forklifts are placed in parallel, and the distance between them allows the forklift forks to be inserted freely; at both ends of the 2 fiberglass - steel composite cylinders for forklifts, there are symmetrically arranged the first longitudinal side beam, the second longitudinal side beam, and the third longitudinal side beam perpendicular to their spatial positions, and the second longitudinal side beam is located between the 2 fiberglass - steel composite cylinders for forklifts, the first longitudinal side beam and the third longitudinal side beam are respectively located at the other ends of the 2 fiberglass - steel composite cylinders for forklifts, and the first longitudinal side beam, the second longitudinal side beam, and the third longitudinal side beam are connected to the ends of the fiberglass - steel composite cylinders for forklifts through the fifth fiberglass - steel bolt connector, and the first longitudinal side beam, the second longitudinal side beam, the third longitudinal side beam, and the 2 fiberglass - steel composite cylinders for forklifts are in a straight line and in a plane; one fiberglass - steel transverse short beam is vertically arranged between the 2 first longitudinal side beams, and the other fiberglass - steel transverse short beam is vertically arranged between the 2 third longitudinal side beams, and the first longitudinal side beam, the third longitudinal side beam, and the "door" - shaped fiberglass - steel transverse short beam are connected by the second angle piece - fiberglass - steel plate - steel sleeve - bolt integrated connector to form the outer frame of the "kou" - shaped bottom fiberglass - steel - bamboo laminated timber frame structure; install the fifth bamboo laminated timber transverse short beam along the transverse direction inside the "kou" outer frame at an interval not exceeding 1.5 meters, install bamboo laminated timber or fiberglass - steel longitudinal middle beams along the longitudinal direction inside the "kou" outer frame in an equally divided form, and the bamboo laminated timber or fiberglass - steel longitudinal middle beams are connected to the fifth bamboo laminated timber transverse short beam and the fiberglass - steel composite cylinders for forklifts;

[0030] Step 4: Assemble the bamboo composite corner posts and bamboo composite side posts around the perimeter; use the second corner piece-glass fiber-steel plate-steel sleeve-bolt integrated connector to install the first bamboo composite corner post spanning the door frame and the second bamboo composite corner post spanning the non-door frame at the four corners of the outer frame of the bottom glass fiber-steel-bamboo composite frame structure, and the centroids of the first and second bamboo composite corner posts and the corresponding corner pieces are on a straight line or the horizontal projection distance between the two centroids is less than one-fifth of the short side length of the bamboo composite corner post; use the second glass fiber-steel bolt connector to install the first, second, third, fourth, and fifth bamboo composite side posts on the outer frame edge of the bottom glass fiber-steel-bamboo composite frame structure; bamboo composite diagonal braces are installed between the first longitudinal side beam and the first bamboo composite corner post and the first bamboo composite side post, and the two bamboo composite diagonal braces form an inverted "V" shape; the third longitudinal side beam and the second bamboo composite... Bamboo composite diagonal braces are installed between the corner posts and the fourth bamboo composite edge posts, and the two bamboo composite diagonal braces form an inverted "V" shape; bamboo composite diagonal braces are installed between the second longitudinal edge beam and the second bamboo composite edge post and the third bamboo composite edge post, and the two bamboo composite diagonal braces form an inverted "V" shape. If a loading / unloading door is installed on this side, no bamboo composite diagonal brace is installed here; a fifth longitudinal edge beam is set directly above the end of the fiberglass-steel composite cylinder for forklifts, and the two ends of the fifth longitudinal edge beam are mounted on the corresponding second longitudinal edge beam, the first longitudinal edge beam, or the first longitudinal edge beam is mounted on top and connected to it by "T"-shaped or "I"-shaped fourth fiberglass-steel bolt connectors. Two bamboo composite diagonal braces are set on the fifth longitudinal edge beam to form a "K"-shaped structural system, and the two ends of the two bamboo composite diagonal braces are connected to the corresponding fifth longitudinal edge beam, the first bamboo composite edge post, or the second bamboo composite edge post by inclined T-shaped fiberglass-steel filler plate bolt connectors.

[0031] Step 5: Assemble the top bamboo-laminated timber frame structure. Connect the top of the second bamboo-laminated timber transverse short beam and the fourth longitudinal side beam to the top of the first bamboo-laminated timber corner post using the first corner piece-glass fiber-steel plate-steel sleeve-bolt integrated connector. Connect the top of the third bamboo-laminated timber transverse short beam and the fourth longitudinal side beam to the top of the second bamboo-laminated timber corner post using the first corner piece-glass fiber-steel plate-steel sleeve-bolt integrated connector. The centroids of the first and second bamboo-laminated timber corner posts and the centroids of the corresponding corner pieces should be on a straight line, or the horizontal projection distance between the two centroids should be less than one-fifth of the short side length of the bamboo-laminated timber corner post. Connect the second bamboo-laminated timber corner post using the second glass fiber-steel bolt. The connectors connect the top of the fourth longitudinal edge beam, the third bamboo engineered wood transverse short beam, and the bamboo engineered wood edge post; bamboo engineered wood diagonal braces are installed between the fourth longitudinal edge beam and the first bamboo engineered wood corner post, between the fourth longitudinal edge beam and the second bamboo engineered wood corner post, and between the fourth longitudinal edge beam and the second bamboo engineered wood transverse short beam using oblique T-shaped fiberglass-steel filler plate bolt connectors; bamboo engineered wood diagonal braces are connected between the two ends of the third bamboo engineered wood transverse short beam and the second bamboo engineered wood corner post using oblique T-shaped fiberglass-steel filler plate bolt connectors; and the fourth bamboo engineered wood transverse short beam is connected between the two fourth longitudinal edge beams using first fiberglass-steel bolt connectors.

[0032] Step Six: Assemble the maintenance structure. Install the bamboo engineered wood panels on the bottom fiberglass-steel-bamboo engineered wood frame structure; install double-leaf end doors between the two first bamboo engineered wood corner posts, and install side doors between the second and third bamboo engineered wood side posts; install the top bamboo engineered wood panels, the first side bamboo engineered wood panels, and the second side bamboo engineered wood panels around the bamboo engineered wood frame structure to form an enclosure structure; treat the bamboo engineered wood with anti-corrosion, anti-mildew, and anti-UV treatment.

[0033] Furthermore, the "K"-shaped structural system formed by the two bamboo composite timber diagonal braces and the fifth longitudinal side beam mentioned in step four can be installed or not.

[0034] Furthermore, the anti-corrosion, anti-mildew, and anti-UV treatment steps described in step six are as follows: The surface of the bamboo laminated timber is treated with an organosilicon-polyurethane composite superhydrophobic coating. This coating is composed of polydimethylsiloxane (PDMS) modified polyurethane (PU) and nano-silica (SiO2). Through the synergistic effect of the micro-nano hierarchical rough structure and low surface energy siloxane groups, a superhydrophobic interface with a static water contact angle (WCA) ≥150° and a sliding angle (SA) ≤10° is formed. Simultaneously, resorcinol-formaldehyde resin (RF) is embedded to fill microporous defects, inhibiting microbial adhesion and corrosive media penetration. A spraying process is used for anti-corrosion, anti-mildew, and anti-UV treatment, constructing a high-performance protective coating on the surface of the bamboo laminated timber. This coating uses organosilicon-modified polyurethane (PDMS-PU) as the matrix, and is modified by adding nano-silica (SiO2) modified with a silane coupling agent (such as KH-570) and resorcinol-formaldehyde resin (RF) to form a composite coating with unique properties. By precisely controlling the proportions of each component, the coating performance is optimized. In PDMS-PU, the ratio of polydimethylsiloxane (PDMS) to polyurethane (PU) is controlled according to the soft segment grafting ratio, combined with modified SiO2 nanoparticles (5%-10%) and RF resin mixed at a mass ratio of 8:1:1 to ensure the multifunctional performance of the coating. Appropriate addition of modified SiO2 enhances the micro-nano hierarchical rough structure of the coating; RF resin is embedded in the coating to fill micropore defects, forming a chemical barrier. This coating possesses excellent comprehensive characteristics: superior superhydrophobicity, strong mechanical durability, good chemical stability, anti-mildew and antibacterial capabilities, and strong environmental adaptability, effectively addressing corrosion, mildew, and biofouling issues in containers under humid, salt spray, and biocontaminated environments. The silicone-polyurethane composite superhydrophobic coating possesses superhydrophobic, anti-corrosion, anti-mildew, and UV-resistant properties, and can achieve anti-biofouling and self-cleaning functions.

[0035] The beneficial effects of this invention are as follows: Using bamboo laminated timber as the structural material, the container possesses characteristics such as light weight, high strength, reliable structural safety, corrosion resistance, impact resistance, fatigue resistance, and freeze resistance. It also reduces the use of steel, aluminum alloys, and other mineral materials, making it more low-carbon and environmentally friendly. The container can be loaded and unloaded using either cranes or forklifts. It features both side doors and top swing doors, resulting in high loading efficiency and accommodating the loading and unloading of various goods. Compared to metal containers, the container of the same size can be more than 20% lighter; the bamboo laminated timber frame container can be used for 8-10 years without large-scale anti-corrosion treatment, reducing maintenance costs by more than 50%. Furthermore, bamboo absorbs a large amount of carbon dioxide during its growth, and its processing also results in relatively low carbon emissions, contributing to the low-carbon and environmentally friendly goals of the container industry.

Bamboo composite diagonal braces 7 are also installed between the second longitudinal edge beam 3-2 and the second and third bamboo composite edge columns 2-2 and 2-3, forming an inverted "V" shape. If a loading / unloading door 13 is installed on this side, then no bamboo composite diagonal brace 7 is installed here. A fifth longitudinal edge beam 3-5 is installed directly above the end of the fiberglass-steel composite cylinder 8 for forklifts. The two ends of 3-5 are equipped with corresponding second longitudinal side beams 3-2, first longitudinal side beams 3-1 or first longitudinal side beams 3-1, and are connected to them by “T” or “I” shaped fourth fiberglass-steel bolts 10-4.

The two ends of the two bamboo composite diagonal braces 7 are connected to the corresponding fifth longitudinal side beam 3-5, first bamboo composite side post 2-1 or second bamboo composite side post 2-2 by diagonal T-shaped fiberglass-steel filler plate bolt connectors 11.

[0076] Step 5: Assemble the top bamboo-laminated timber frame structure.

[0078] The two bamboo composite timber diagonal braces 7 in step four and the fifth longitudinal side beams 3-5 form a "K" shaped structural system, which can be installed or not.

[0079] The steps for anti-corrosion, anti-mildew and anti-UV treatment in step six are as follows: The surface of bamboo laminated timber is treated with an organosilicon-polyurethane composite superhydrophobic coating. This coating is made of polydimethylsiloxane (PDMS) modified polyurethane (PU) and nano-silica (SiO2). Through the synergistic effect of micro-nano hierarchical rough structure and low surface energy siloxane groups, a superhydrophobic interface with a static water contact angle (WCA) ≥150° and a sliding angle (SA) ≤10° is formed. At the same time, resorcinol-formaldehyde resin (RF) is embedded to fill microporous defects, inhibiting the adhesion of microorganisms and the penetration of corrosive media.

[0080] Preferably, a high-performance protective coating, namely an organosilicon-polyurethane composite superhydrophobic coating treatment, is constructed on the surface of bamboo engineered wood using a spraying process. The main raw materials, including polydimethylsiloxane-modified polyurethane (PDMS-PU) prepolymer, KH-570 modified nano-silica (SiO2) particles, resorcinol-formaldehyde resin (RF), and ethyl acetate solvent, are precisely weighed according to the formula. Before coating, the surface of the bamboo engineered wood is lightly sanded along the bamboo grain to remove burrs and grease, and then wiped clean with ethanol to ensure a surface roughness Ra = 1.5-2.0 μm, cleanliness ≥95%, and complete dryness, providing an ideal substrate for coating adhesion. An F2 type spray gun is used for spraying. Before spraying, the spray gun pressure is adjusted to 0.5 MPa, maintaining a nozzle-to-bamboo engineered wood distance of 15 cm. Two coats are applied evenly, each with a wet film thickness of approximately 50 μm. After spraying, the coating is first dried at room temperature (25℃±2℃) for 24 hours, then cured in a 60℃ oven for 2 hours to form a superhydrophobic coating with a total thickness of 80-100μm. After the coating has dried and cured, all properties, such as superhydrophobicity, corrosion resistance, and mildew resistance, are comprehensively tested. If the performance does not meet the standards, factors such as raw material ratio, spraying pressure, and curing conditions are analyzed in a timely manner, and the process is adjusted accordingly.

[0081] The silicone-polyurethane composite superhydrophobic coating possesses superhydrophobic, anti-corrosion, and anti-mildew properties, and can also achieve anti-bioadhesion and self-cleaning functions.

[0082] This invention discloses a method for manufacturing a container using bamboo laminated timber as the structural material. The purpose is to reduce the weight, ensure structural safety and reliability, and improve corrosion resistance, impact resistance, fatigue resistance, freeze resistance, and UV resistance. At the same time, it develops and utilizes biomass material resources to reduce the use of mineral materials such as steel and aluminum alloys, making it more low-carbon and environmentally friendly.
