Description

Technical Field

[0001] The present invention relates to the fields of construction, architecture, and industrial design, and particularly to lightweight and efficient structural connecting members made of composite materials containing fibers and binders for use in the construction and assembly of structures such as buildings, bridges, warehouses, and equipment.

[0002] In the field of construction and manufacturing of structural parts or members having the ability to withstand loads and / or mechanical stresses, reducing the amount of material used and the weight of the members is a priority in the industry for both economic and sustainability reasons in order to save energy, reduce carbon emissions, and use raw materials more efficiently.

[0003] In some industries (especially the construction and transportation industries), new technologies and lightweight composite materials are being utilized to achieve the required structural performance while meeting environmental sustainability goals. In such situations, composite materials and wood are becoming increasingly mainstream as they are each suitable for digital manufacturing, have high mechanical strength, are sustainable, and have less impact on the environment.

Background Art

[0004] In many industries, there is an increasing need to introduce new technologies and more sustainable materials in the process. In some industries, this is extremely important in terms of CO2 emissions and the overall impact on the environment. The construction and transportation industries are the two major industries that emit the most greenhouse gases in the world.

[0005] In the transportation industry, the demand for lighter structural materials has increased significantly in order to reduce fuel consumption and greenhouse gas emissions.

[0006] The construction industry, on the other hand, is one of the industries with the highest consumption of materials and energy, as well as one of the highest emitters of carbon dioxide (CO2). In recent years, there has been a significant increase in demand for more sustainable and environmentally friendly building materials in order to reduce CO2 emissions and lessen the environmental burden on the industry as a whole. In this context, wood is becoming increasingly mainstream due to its high sustainability and low environmental impact, although conventional materials (such as concrete and steel) remain the most widely used despite their high environmental impact. Replacing these CO2-emitting materials (concrete and steel) with wood is one of the most effective ways to reduce CO2 emissions. Currently, leading this trend is cross-laminated timber (CLT), which is mainly used in the construction of walls, ceilings, and floors, followed by plywood and oriented strand board (OSB). Wood as a structural construction material has several limitations, one of which is the lack of strong, durable, and mechanically sound wooden structural connectors for various types of buildings and other structures. This is usually solved by using metal components, but this increases the carbon dioxide emissions of wooden structures, increases the size of wooden members, and reduces the potential positive impact of wooden construction.

[0007] In the architecture and construction industries, connecting components play a crucial role in the design, stability, safety, and efficiency of structures. In this regard, developing high-performance structural connecting components made from wood fiber-based composite materials presents an excellent opportunity to improve efficiency and sustainability in construction.

[0008] Description of related technologies Against this backdrop, there is a clear need for novel solutions that provide structural connecting materials that are environmentally sustainable, lightweight, and resistant to heavy loads and mechanical stresses.

[0009] Japanese Patent No. 5633041 (Patent Document 1) of the Hokkaido Research Organization presents a joint structure that enables a rigid hardwood joint. This joint structure includes a set of main wooden boards that form part of a hardwood laminated structure (layer A), and a set of secondary wooden boards that form part of a hardwood laminated structure (layer B) is inserted into or crossed between the boards of the hardwood laminated structure (layer A) at any position and angle, and the boards are pressed together to create an overlapping portion. As a result, the non-overlapping portions of the hardwood laminated structure (layers A and B) are incorporated into a compact hardwood laminated joint structure whose thickness is approximately equal to the thickness of the overlapping portion. These joints only serve to connect elements on the same plane, and their mechanical performance depends on the properties of the wood, with most of the fibers not oriented in the optimal direction, making them insufficient for large structures that require high mechanical strength.

[0010] European Patent Publication No. 3862499 (Patent Document 2) of Suzhou University of Science and Technology discloses a steel-wood composite joint including a square tube column, a steel-wood composite beam, and a beam-column connecting assembly that connects the square tube column and the steel-wood composite beam. Each square tube column includes a connecting corner column and a connecting side plate. While these joints have high load-bearing capacity, they require a large amount of steel, and the manufacturing process has a significant environmental impact.

[0011] Ulrich Wallner's U.S. Patent No. 8,387,330 (Patent Document 3) describes a system for manufacturing structures such as trusses from modular bar elements and connecting elements that interconnect at least two bar elements, where the bar elements and connecting elements are interconnected to form a truss. In this system, each connecting element is manufactured from a rigid and renewable raw material produced by photosynthesis in plants such as wood or bamboo. This system uses connecting elements with low load-bearing capacity.

[0012] In some industries, carbon fiber or glass fiber reinforced plastics are widely used as materials for manufacturing lightweight objects. While these materials are lightweight and strong, they are far from sustainable. This is because their production volume is very high in terms of CO2 emissions, their structural performance does not always meet the standards required by the construction industry, and their limited productivity and high cost make them difficult to use on the scale required by the construction industry.

[0013] Sustainable composite materials based on other plant fibers such as jute, flax, and hemp are also known. While these sustainable technologies are suitable solutions for lightweight structures, they do not meet the mechanical performance requirements of the construction and transportation industries due to their low structural performance and / or high weight, and they have productivity and cost limitations, similar to synthetic fibers such as carbon fiber and glass fiber.

[0014] In summary, the most sustainable alternatives to currently available construction connecting members fail to meet high mechanical and / or structural performance, cost, and volume requirements, while options that do meet these requirements are not sustainable. Therefore, there is a need for novel structural members for connecting building elements that achieve the high structural performance required by the construction and other industries while simultaneously being made from sustainable materials.

[0015] Against this backdrop, the present invention, a new type of oriented fiber structure connecting member for linking at least two construction elements, offers a solution that meets the demand for lightweight materials that are more sustainable than currently used materials such as aluminum, metals, and reinforced plastics, while also providing superior mechanical strength compared to other wood-based or natural fiber-based elements.

[0016] [Patent Document 1] Japanese Patent No. 5633041 [Patent Document 2] European Patent Publication No. 3862499 [Patent Document 3] U.S. Patent No. 8387330 [Overview of the project] [Problems that the invention aims to solve]

[0017] The objective of this invention is to contribute to solving the problem of high CO2 emissions in various industries, particularly the construction industry, by providing a new type of structural member for connecting construction elements. This invention includes an improved design and manufacturing method, as well as an innovative composite material, to provide a composite component comprising wood fibers or wood strands and a binder, resulting in a durable and lightweight component made from renewable materials. This is useful in reducing the weight of the connecting members and the structures that use them, as well as improving the energy efficiency of buildings and structures that use these connecting members. [Means for solving the problem]

[0018] The connecting member of this invention may feature a wide variety of specific designs depending on the requirements of each case. First, a design drawing is obtained based on the specific requirements of the case, and then the member is manufactured according to the design drawing by pressing multiple layers consisting of at least one type of binder and multiple oriented fibers (preferably wood) under high pressure. The pressing process may require a mold in the desired shape of the connecting member, or it may be performed by pressing a blank block of composite material made of oriented fibers and binder, and then machining is performed until the member is formed according to the required design.

[0019] Thus, a new type of structural connection member is introduced, whose shape, size, and mechanical strength characteristics can vary according to the specific requirements of each case. Such a novel structural connection member can connect all types of construction elements used in the construction of any structure that requires the assembly and / or joining of columns, beams, trusses, walls, rails, profiles, slats, and buildings, houses, bridges, warehouses, huts, containers, vehicles, tents, equipment, street equipment, sports facilities, fences, and all kinds of construction elements.

[0020] Therefore, in the context of this specification, it is important to understand the terms "construction" and "constructional" in the broadest sense, such as assembly and installation, from the perspective of the requirements of all industries, and also in the specific sense within the construction, engineering, and architectural industries.

[0021] The following provides a detailed description of the present invention together with the drawings, which are also part of this specification.

[0022] It should be noted that the drawings only serve as an aid for better understanding of the present invention, and neither represent the members and their components in their final form nor in actual scale or proportional scale. These drawings are presented in a form that explains the important elements of the main embodiments of the present invention disclosed in this specification and may not include elements generally known in the prior art.

[0025] As used in this invention, the term "arm" refers to one of the extensions of a structural connecting component used to connect one or more individual construction elements.

[0026] As used in this invention, the term "to machine" or "machining" refers to the action of modifying a block or material piece by cutting, planing, carving, polishing, and any process that removes material from the block or material piece in general, to obtain a smaller molded piece or molded part than the original block or material piece, which was "contained within" the block or material piece.

[0027] As used in this invention, the term "blank block" refers to a piece of material, a slab of material, or a block (of material, whether or not it is a composite material), from which a component or part is obtained by removing material through a "machining" process (as defined in the previous paragraph). On the other hand, "blank plate" refers to the same as a blank block, but thinner or flatter, and "composite blank plate" refers to a thicker blank plate or blank block formed by joining two or more blank plates.

[0028] As used in this invention, the term "axis" refers to the most central, virtual line(s) running along the longitudinal axis within the shape of the connecting component of this invention, particularly its "arm" (as defined at the beginning of this section). Figures 5A, 5B, 5C, and 6 illustrate this concept.

[0029] As used in this invention, the term "layer layout" refers to the operation of dividing a three-dimensional digital model or object design into a series of parallel layers, which is generally performed by a computer program in a situation where the three-dimensional object is later manufactured layer by layer.

[0030] As used in this invention, the term "fraction" or "fractions" refers to a sub-component that makes up one of the parts or components described in this invention, and is generally used in a manufacturing method in which these sub-components or fragments are manufactured individually and then assembled and glued together to obtain a finished part or component.
