Description

Technical Field

[0001] The invention relates to a bamboo-wood composite wall, belonging to the technical field of assembled green building materials. Background Art

[0002] According to a 2021 report by the United Nations Environment Programme, the building and construction industry accounts for 32% of global energy consumption and 34% of carbon dioxide emissions. In 2020, China's building lifecycle carbon emissions accounted for approximately 50% of the country's total carbon emissions.

[0003] Under the dual carbon strategy of achieving carbon peak and carbon neutrality, green building materials have become a key development direction for the construction industry. Wood and bamboo, as renewable natural building materials, not only absorb carbon dioxide and release oxygen, but also possess excellent mechanical properties, environmental friendliness, and sustainability. Bamboo, a renewable resource with a high growth rate, has a carbon sequestration efficiency over 1.5 times that of trees. China's bamboo industry output value reached 300 billion yuan in 2022, demonstrating significant ecological and economic value. Bamboo processing has low carbon emissions, and its load-bearing strength even exceeds that of steel. Existing technologies have introduced large-scale composite walls made of wood, bamboo, and bamboo-wood composite structures. However, existing bamboo-wood materials, when combined into large-scale, load-bearing walls, generally employ solid structures such as reconstituted wood, reconstituted bamboo, cross-laminated timber (CLT), or bamboo-wood composites. While these solid structures increase strength and load-bearing capacity, they also increase material usage and cost. For example, cross-laminated timber, made by planing solid wood boards on all four sides and gluing them together in multiple layers, results in a higher market price. To make large-sized bamboo boards, bamboo tubes must be split or steamed at high temperatures to flatten the bamboo walls to obtain bamboo strips. Because bamboo has a large diameter and thick walls at the root and a small diameter and thin walls at the tip, the width and thickness of the bamboo strips at both ends vary greatly. Processing them to the same thickness and width at both ends wastes a lot of materials and labor costs. Therefore, bamboo plywood is more expensive than wood plywood. Reconstructing bamboo strips and wood requires a lot of adhesives and resins, and the density can even exceed 1.2t / m 3 , more expensive, and its high density makes it less effective at insulating, typically requiring additional insulation layers on the walls. More importantly, processed bamboo strips, no matter how they are assembled, no longer possess the same axial support strength as the original bamboo. These factors combined have limited its widespread application in the construction industry.

[0004] Therefore, there is an urgent need to develop a new type of bamboo-wood composite wall that can reduce costs while ensuring its load-bearing capacity and structural stability, increasing thermal insulation, and being suitable for factory assembly line operations to meet the modern building requirements for high efficiency, high strength, low carbon, environmental protection and sustainability of wall panels. Summary of the Invention

[0005] The present invention aims to solve the deficiencies of the prior art and provides a bamboo-wood composite wall.

[0006] The technical solution of the present invention to solve the above technical problems is as follows: A bamboo-wood composite wall comprises a panel and a load-bearing structure. The load-bearing structure comprises a plurality of bamboo tubes arranged on one side of the panel, and the outer sides of the bamboo tubes are filled with an intermediate material.

[0007] The beneficial effects of the present invention are: The present invention provides multiple bamboo tubes between the panels, which are hollow bamboo node structures. The hollow structure greatly reduces the overall weight of the wall, and the bamboo node structure and the vertical compressive strength of the bamboo ensure that the bamboo tubes have a high supporting capacity, which helps to improve the bearing capacity of the wall, improve the impact resistance and bending resistance of the wall, and improve the bearing capacity and structural stability while ensuring the lightweight of the wall. Compared with the solid plate structure, the sandwich structure is a lightweight structure with a more reasonable material distribution, and the internal structure of the bamboo tube forms an independent cavity, which is independently sealed in the middle material, so that the overall thermal insulation effect is better.

[0008] On the basis of the above technical solution, the present invention can also make the following improvements: Furthermore, the panels are provided in two pieces, and the load-bearing structure is provided between the two panels.

[0009] The beneficial effect of adopting the above-mentioned further technical solution is: through two panels, multiple bamboo tubes of the load-bearing structure are sandwiched in the middle, so that the bamboo tubes can better play their load-bearing role, improve the bearing capacity of the bamboo tubes, and the panels can also provide a certain bearing effect; further, by filling the outside of the bamboo tubes with intermediate materials, in addition to providing thermal insulation, the bamboo tubes can also be fixed, limiting the lateral displacement of the bamboo tubes when subjected to force, enhancing the connection strength between the bamboo tubes and the panels, forming a whole, and further improving the bearing capacity and structural stability of the composite wall.

[0010] Furthermore, the small-diameter ends of adjacent bamboo tubes face opposite directions.

[0011] The beneficial effect of adopting the above-mentioned further technical solution is: due to the characteristics of the bamboo growth process, the shape of the bamboo is generally large in diameter at the root, i.e., the large diameter end, and small in diameter at the top, i.e., the small diameter end. If the bamboo tubes are arranged in a forward direction, the large diameter ends of adjacent bamboo tubes are in contact or close to each other, but the distance between the small diameter ends will be relatively far, which may cause the small diameter ends of the bamboo tubes to deviate or bend. Due to the particularity of the bamboo tube structure, if the bamboo tube is subjected to vertical force, its multiple bamboo node structures can bear weight and disperse the force well. However, if the top of the bamboo tube is greatly deviated or bent, it may cause the force direction of the bamboo tube to change, and the bamboo node cannot play its maximum role when bearing weight, affecting the load-bearing effect. The present invention makes the small diameter ends of adjacent bamboo tubes face oppositely, so that the bamboo tube arrangement presents an alternating arrangement of large diameter ends and small diameter ends, reducing the space for the small diameter ends of the bamboo tubes to deviate or bend when subjected to force, thereby reducing the space that needs to be filled with intermediate materials inside, saving costs, and increasing the number of bamboo tube arrangements, thereby improving the load-bearing capacity of the bamboo tubes of the present invention.

[0012] Furthermore, the bamboo tubes are arranged continuously.

[0013] The beneficial effect of adopting the above-mentioned further technical solution is that the bamboo tubes are arranged continuously, so that adjacent bamboo tubes are arranged closely, thereby improving the overall load-bearing capacity of the wall.

[0014] Furthermore, the load-bearing structure further includes wooden columns, which are arranged between the bamboo tubes and parallel to the bamboo tubes.

[0015] The beneficial effects of adopting the above-mentioned further technical solution are: the cross-sectional area and number of wooden columns can be adjusted according to the required bearing capacity of the wall. Large-section wooden columns are used as load-bearing structures and are arranged between the panels, which can improve the bearing capacity of the composite wall without causing a significant increase in the weight of the wall. In addition, the vertical wooden columns and the crossbeams can be connected with mortise and tenon joints, round wooden sticks or long wood screws to form an external frame, which is more convenient for connecting adjacent wall panels and floor slabs.

[0016] Furthermore, the wooden columns are square timber, round timber, flat wooden strips, wooden boards, glued timber or bamboo-wood composite boards.

[0017] Furthermore, the opposite surfaces of the adjacent bamboo tubes are flattened.

[0018] The beneficial effect of adopting the above-mentioned further technical solution is: the contact surfaces or adjacent surfaces of the bamboo tubes are flattened, so that the bamboo tubes can be arranged more closely, further improving the bearing capacity of the composite wall.

[0019] Furthermore, the bamboo-wood composite wall also includes a frame structure, and the frame structure includes a beam plate.

[0020] Furthermore, the frame structure also includes side panels arranged on the left and right sides of the panel.

[0021] The beneficial effect of adopting the above-mentioned further technical solution is that the upper and lower ends of the bamboo tube are in contact with the crossbeam plate of the frame structure and are combined together. The frame structure and the two panels wrap the bamboo tube and the middle material to form an integrated wall panel, which is more helpful to improve the bearing capacity of the wall, improve the impact resistance and bending resistance of the wall, so that the composite wall of the present invention can be used as a filling inner wall or as an outer wall. The frame structure can provide better support and load-bearing effects and achieve an aesthetic effect.

[0022] Furthermore, the panel and the frame structure are selected from any one of solid wood boards, laminated boards, OSB boards (Oriented Strand Board), glued wood, spliced wood boards, spliced bamboo boards, density boards, honeycomb boards, fiberboards or bamboo-wood composite boards.

[0023] Furthermore, a flame retardant layer is provided on the outer side of the panel.

[0024] Furthermore, the flame retardant layer is selected from any one of wood board, bamboo board, wood-bamboo composite board, aerogel material, fireproof polyurea or fireproof board.

[0025] The beneficial effect of adopting the above further technical solution is that by providing the flame retardant layer, the composite wall of the present invention can be adapted to the application scenarios of interior and exterior walls of buildings, thereby improving the practicality of the composite wall.

[0026] Furthermore, the intermediate material is adhesive, foam or aerogel.

[0027] The beneficial effects of adopting the above-mentioned further technical solution are: by filling the composite wall with adhesive, foam or aerogel, the connection strength between the bamboo tubes, between the wooden columns and / or between the bamboo tubes and the wooden columns and panels in the wall is improved, the lateral displacement of the bamboo tubes when subjected to force is limited, and the bamboo tubes, wooden columns, beams and panels are formed into a whole, thereby improving the overall strength. In addition, the filled intermediate material has a thermal insulation effect, thereby improving the practicality of the composite wall of the present invention.

[0028] Furthermore, the intermediate material is a thermal insulation material.

[0029] The beneficial effects of adopting the above further technical solution are: improving the thermal insulation performance of the composite wall by filling the thermal insulation material, reducing the use cost, and improving the practicality of the present invention.

[0030] Furthermore, the panel is provided with a window or a door opening.

[0031] The beneficial effect of adopting the above further technical solution is that by arranging door openings or windows on the panels, the composite wall of the present invention can be installed with windows or doors as needed when used as an exterior wall.

[0032] Furthermore, two or more bamboo tubes serve as a supporting group, and cavities are provided between adjacent supporting groups.

[0033] The beneficial effect of adopting the above further technical solution is: on the basis of ensuring the bearing capacity, by providing the cavity, the weight of the composite wall of the present invention is further reduced, thereby saving costs.

[0034] Furthermore, the bamboo tubes are arranged continuously, and the opposite surfaces of adjacent bamboo tubes are flattened.

[0035] Furthermore, the bamboo tube array has two or more rows.

[0036] The beneficial effect of adopting the above-mentioned further technical solution is that when the composite wall of the present invention is used as the load-bearing wall of a high-rise building, the wall is required to have a higher bearing capacity. If the strength of a single row of bamboo tubes cannot meet the bearing capacity required by the wall, two or more rows of bamboo tubes can be arranged in the wall as needed, which increases the bearing capacity and improves the thermal insulation effect.

[0039] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0040] Example 1 See also Figure 1-2 A bamboo-wood composite wall includes a panel 1 and a load-bearing structure. The load-bearing structure includes multiple bamboo tubes 4 arranged on one side of the panel 1. The multiple bamboo tubes 4 are arranged in parallel, and the outer side of the bamboo tubes 4 is filled with an intermediate material 6.

[0041] There are two panels 1 , and the load-bearing structure is arranged between the two panels 1 .

[0042] The bamboo tubes 4 are arranged continuously.

[0043] The opposite surfaces of the adjacent bamboo tubes 4 are flattened.

[0044] The panel 1 is selected from any one of solid wood panels, laminated panels, OSB panels, spliced wood panels, spliced bamboo panels, density boards, honeycomb panels, fiberboards, or bamboo-wood composite panels. In this embodiment, the panel 1 is selected from laminated panels. Specifically, the laminate is RLT (rotary-cut laminated timber). RLT is a large-scale, thick-core, cross-laminated engineered wood with widths up to 3.2 meters, lengths up to 12 meters, and thicknesses ranging from 2 cm to 40 cm. Due to its large length and width, RLT can be produced on factory lines with a high degree of automation, allowing for both standardized batch production and customized production. Furthermore, bamboo and wood have a higher load-bearing ratio than concrete and steel, and the enlarged cross-section of bamboo and wood materials offers excellent fire resistance. For example, the burning rate of heavy wooden structures is affected by the surface carbonization layer, which is only 0.6 mm to 0.7 mm per minute. Studies have also shown that the fire resistance rating of CLT is REI90, which means that it can maintain sufficient load-bearing capacity within 90 minutes of burning, while the REI rating of unprotected steel is only 15, and its fire resistance is far inferior to CLT and RLT.

[0045] The outer surface of the panel 1 is provided with a flame-retardant layer. The flame-retardant layer is selected from any one of wood, bamboo, wood-bamboo composite, aerogel, fire-resistant polyurea, or fireproof board. In this embodiment, the flame-retardant layer is fireproof board. As a flame-retardant layer on the exterior wall, it can improve the performance and service life of the wall.

[0046] The intermediate material 6 is a heat-insulating material, or the intermediate material 6 is an adhesive, foam or aerogel. In this embodiment, the intermediate material 6 is foam. In addition to providing good connection strength, the structure of the foam can improve the heat insulation effect of the wall.

[0047] Example 2 See also Figure 3-Figure 6 A bamboo-wood composite wall, which is different from the embodiment 1 in that the small diameter ends 402 or large diameter ends 401 of the adjacent bamboo tubes 4 in this embodiment face opposite directions. Due to the characteristics of the bamboo growth process, the shape of bamboo is generally large in diameter at the root, i.e., large diameter end 401, and small in diameter at the top, i.e., small diameter end 402 (see Figure 7), if the bamboo tubes 4 are arranged in a forward direction, the large-diameter ends of adjacent bamboo tubes 4 are in contact or close to each other, but the distance between the small-diameter ends 402 will be relatively far, which may cause the small-diameter ends 402 of the bamboo tubes 4 to deviate or bend. Due to the particularity of the structure of the bamboo tubes 4, if the force direction of the bamboo tubes 4 is vertical, its multiple bamboo node structures can bear the weight and disperse the force well. However, if the top of the bamboo tube 4 is greatly deviated or bent, it may cause the force direction of the bamboo tube 4 to change, and the bamboo nodes cannot play a role when bearing weight, affecting the load-bearing effect. The present invention arranges the bamboo tubes 4 with the large-diameter ends 401 and the small-diameter ends 402 alternatingly arranged by the small-diameter ends 402 of the adjacent bamboo tubes 4 in opposite directions, thereby reducing the space for the small-diameter ends 402 of the bamboo tubes 4 to deviate or bend when bearing weight, thereby improving the load-bearing capacity of the bamboo tubes 4 of the present invention, and at the same time making the arrangement between adjacent bamboo tubes 4 tighter, so that more bamboo tubes 4 can be arranged, the number of bamboo tubes 4 is increased, and the overall load-bearing capacity is increased when a large load-bearing force is required.

[0048] The rest is the same as in Example 1 and will not be described in detail.

[0049] Example 3 See also Figure 8-Figure 9 , a bamboo-wood composite wall. Different from Example 2, this embodiment also includes a frame structure, which includes crossbeams 2 arranged on the upper and lower sides of the bamboo tube 4. In addition to providing a covering effect on the upper and lower sides of the composite wall, the crossbeams 2, as a load-bearing wall, can play a good overall supporting role, sharing the force of local bamboo tubes 4 and wooden columns 5 to the surrounding bamboo tubes 4 and wooden columns 5, thereby improving the bearing capacity of the composite wall.

[0050] The crossbeam 2 is selected from any one of solid wood, plywood, laminate, OSB, spliced wood, spliced bamboo, density board, fiberboard or bamboo-wood composite board. In this embodiment, the frame structure is selected from plywood, specifically plywood beams.

[0051] The rest is the same as in Example 2 and will not be described in detail.

[0052] Example 4 See also Figure 10-11 A bamboo-wood composite wall, based on Example 3, further comprises a frame structure comprising side panels 3 disposed on the left and right sides of the composite wall. The side panels 3 provide a covering effect on the left and right sides of the composite wall, enhancing the composite wall's aesthetics. They also function as support beams, forming a cohesive composite wall and creating a skin effect that enhances the composite wall's load-bearing capacity. Furthermore, the side panels 3 can be connected to the crossbeam 2 using mortise and tenon joints, round wooden rods, or long wood screws to form a frame structure, further facilitating the connection between adjacent wall panels and floor slabs.

[0053] The rest is the same as Example 3 and will not be described in detail.

[0054] Example 5 See also Figure 12 , a bamboo-wood composite wall. Different from Example 4, the load-bearing structure of this embodiment also includes wooden columns 5, which are arranged between the bamboo tubes 4, and the wooden columns 5 are arranged parallel to the bamboo tubes 4, and the wooden columns 5 and the bamboo tubes 4 are arranged alternately.

[0055] The wooden columns 5 are square timber, round timber, flat wooden strips, wooden boards, glued timber or bamboo-wood composite boards.

[0056] In this embodiment, the wooden columns 5 are made of glued wood.

[0057] The rest is the same as Example 4 and will not be described again.

[0058] Example 6 See also Figure 13 , a bamboo-wood composite wall, which is different from Example 5 in that two or more bamboo tubes 4 in this embodiment are continuously arranged as a load-bearing group, a cavity is provided between adjacent load-bearing groups, and the wooden columns 5 are provided in the cavity of the bamboo tubes 4.

[0059] The rest is the same as Example 5 and will not be described in detail.

[0060] Example 7 See also Figure 15 , a bamboo-wood composite wall, which is different from Example 4 in that two or more bamboo tubes 4 in this embodiment are continuously arranged as a load-bearing group, and a cavity is provided between adjacent load-bearing groups.

[0061] The rest is the same as Example 4 and will not be described again.

[0062] Example 8 See also Figure 14 A bamboo-wood composite wall, based on Example 4, is provided in this embodiment as an exterior wall. Panel 1 is provided with a window 7 or door opening. In this embodiment, the panel 1 is provided with windows 7. The windows 7 on two panels 1 are positioned opposite each other. The edges of the windows 7 on the two panels 1 are connected by a partition 8, thereby forming a window shape in the composite wall. The partition 8 is selected from any one of solid wood panels, glulam, laminated wood, OSB, spliced wood panels, spliced bamboo panels, density fiberboard, fiberboard, or bamboo-wood composite panels. In this embodiment, the partition 8 is a laminate, specifically, laminated glulam.

[0063] Example 9 See also Figure 16, a bamboo-wood composite wall. Different from Example 1, the bamboo tubes 4 in this embodiment are provided in two rows, and the two rows of bamboo tubes 4 are staggered, that is, the bamboo tubes 4 in one row are respectively arranged in the gaps of the bamboo tubes 4 in the other row, so that the arrangement between the two rows of bamboo tubes 4 can be made tighter, while improving the bearing capacity of the wall and the thermal insulation effect.

[0064] Example 10 See also Figure 17 , a bamboo-wood composite wall, which is different from Example 4 in that the bamboo tubes 4 in this embodiment are provided with two rows, and the two rows of bamboo tubes 4 are aligned, and the small diameter ends 402 or large diameter ends 401 of the adjacent bamboo tubes 4 in the two rows are facing oppositely. Since the small diameter ends 402 or large diameter ends 401 of the bamboo tubes 4 in the same row are facing oppositely, when the bamboo tubes 4 are provided in two or more rows, the bamboo tubes 4 can be aligned, and the arrangement between the two rows of bamboo tubes 4 can also be ensured to be tight, thereby improving the bearing capacity of the wall while improving the thermal insulation effect.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
