Technical Field
[0001] This utility model belongs to the field of prefabricated building materials technology, specifically, it relates to a functional prefabricated wall using bamboo oriented strand board as the main material. Background Technology
[0002] The construction industry is currently placing increasingly higher demands on wall structures, and traditional wall materials and structures have limitations in some aspects. Traditional concrete walls, brick walls, and other structures suffer from problems such as long construction cycles, high energy consumption, and poor customizability. At the same time, the market demand for more environmentally friendly, high-performance, and sustainable building materials and structures is gradually increasing.
[0003] Functional prefabricated wall systems have emerged and are gradually gaining attention due to their advantages such as efficient construction, flexible customization, and superior performance. However, current functional prefabricated wall systems on the market still face some challenges in material selection and structural design, requiring more innovative solutions to promote the industry's development.
[0004] Meanwhile, bamboo oriented strand board (OSB), as an environmentally friendly, sustainable, and carbon-sequestering building material, is an ideal wall material due to its strength, lightweight, and plasticity. The processing technology for bamboo OSB is relatively mature, enabling mass production. By adjusting the production process, various functional bamboo OSBs can be produced, including waterproof, flame-retardant, and finish-free panels. However, current research on how to better utilize bamboo OSB to prepare functional prefabricated walls remains relatively limited. Utility Model Content
[0005] To address the lack of research on functional prefabricated walls using bamboo oriented strand board (OSB) as the main material in existing technologies, this utility model provides a functional prefabricated wall system. Using OSB as the main material, it fully leverages the advantages of bamboo and, through the integration of multiple functional modules, endows the wall with multiple functions such as heat insulation, sound insulation, waterproofing, flame retardancy, pipeline integration, and decoration-free operation. Furthermore, the wall can be manufactured through prefabricated functional modules, improving production efficiency.
[0006] The specific technical solution adopted by this utility model is as follows:
[0007] A functional prefabricated wall includes a waterproof module, a first thermal insulation module, a first pipeline integration module, a sound insulation module, a second pipeline integration module, a second thermal insulation module, a flame-retardant module, and a surface-free module arranged in sequence.
[0008] The waterproof module is a functional module made by adding a waterproofing agent to bamboo oriented strand board;
[0009] Both the first insulation module and the second insulation module are formed by a first receiving frame and insulation material filled inside the first receiving frame; the first receiving frame is a frame formed of bamboo oriented strand board;
[0010] Both the first pipeline integration module and the second pipeline integration module are structural modules formed by opening pipeline channels inside bamboo oriented strand board.
[0011] The sound insulation module is formed by a second receiving frame and sound insulation material filled inside the second receiving frame; the second receiving frame is a frame formed of bamboo oriented strand board;
[0012] The flame-retardant module is a functional module made by adding flame retardants to bamboo oriented strand board;
[0013] The unfinished module is a bamboo oriented strand board with bamboo shavings laid on the surface.
[0014] Preferably, the functional prefabricated wall also has a window module extending through its thickness; the functional prefabricated wall has a window in the thickness direction for housing the window module. The window module includes two window fixing side plates that are snapped onto the inner edge of the window, and window material that is snapped between the two window fixing side plates.
[0015] Generally, the bamboo oriented strand board used in the above-mentioned functional modules has a density of not less than 0.9 g / cm³. 3 Bamboo oriented strand board with a static bending strength of not less than 75 MPa, an elastic modulus of not less than 9000 MPa, and an internal bond strength of not less than 1.5 MPa.
[0016] Furthermore, this functional prefabricated wall combines various functional modules together through a cold-pressing composite process.
[0017] Preferably, the bamboo oriented strand board in the unfinished module uses PF as an organic adhesive to give the functional module better weather resistance; the bamboo oriented strand board in the waterproof module uses pMDI as an organic adhesive to control the release of extremely low formaldehyde, reaching the ENF level.
[0018] The thickness of the aforementioned bamboo oriented strand board is generally selected according to the total design thickness requirements of the functional prefabricated wall, with specifications such as 10 mm, 15 mm, 20 mm, and 28 mm.
[0019] Furthermore, both the first and second receiving frames are obtained by uniformly opening regular holes in bamboo oriented strand board.
[0020] The shape of the holes can be square, circular, triangular, etc.
[0021] Furthermore, the total area of the holes in the first and second housing frames accounts for 80% to 90% of the total area of the bamboo oriented strand board used in this functional module; and sufficient thermal insulation and sound insulation materials are filled accordingly to ensure adequate thermal insulation and sound insulation effects.
[0022] Generally, thermal insulation materials can be selected from commercially available conventional thermal insulation materials such as mineral wool, glass wool, rock face, and aerogel; while sound insulation materials can be selected from commercially available conventional sound insulation materials such as glass wool and rock face.
[0023] Generally, the amount of waterproofing agent added in the waterproof module and the amount of flame retardant added in the flame retardant module are 1.0% to 1.5%, based on the total mass of bamboo oriented strand board used in the functional module.
[0024] Furthermore, both the first and second pipeline integration modules also have prefabricated socket switch channels formed on the surface for installing sockets during application.
[0025] The functional prefabricated wall system with a novel structure provided by this utility model uses bamboo oriented strand board (OSB) as the main material, fully utilizing the advantages of bamboo such as high strength, lightweight, and plasticity. Multiple functional modules are combined through a rational arrangement, comprehensively ensuring that the functional prefabricated wall system simultaneously provides thermal insulation, sound insulation, waterproofing, flame retardancy, surface finishing, and pipeline installation, essentially meeting all the performance requirements of prefabricated wall materials. This functional prefabricated wall system can be manufactured by prefabricating the various functional modules and then assembling them, significantly improving production efficiency.

[0034] The functional prefabricated wall provided by this utility model will be described below with reference to the accompanying drawings and specific embodiments. However, those skilled in the art will understand that the following embodiments are merely specific examples of the functional prefabricated wall of this utility model and are not intended to limit all of them. Rather, these embodiments are provided to explain the specific structure and function of this utility model, thereby enabling other those skilled in the art to understand the various embodiments of this utility model and various modifications suitable for specific intended applications.
[0035] It should be noted that in the following embodiments, in order to clearly describe each functional module, multiple functional modules are defined by terms such as "first" and "second". However, these definitions are not used to distinguish them functionally, but only to distinguish the same functional modules in different locations by numbering.
[0036] Example 1
[0037] like Figure 1 As shown, this embodiment provides a functional prefabricated wall, which includes a sound insulation module 1 located in the core, a first pipeline integration module 21 and a second pipeline integration module 22 arranged on both sides of the sound insulation module 1, a first thermal insulation module 31 arranged outside the first pipeline integration module 21, a second thermal insulation module 32 arranged outside the second pipeline integration module 22, a waterproof module 4 arranged outside the first thermal insulation module 31, a flame-retardant module 5 arranged outside the second thermal insulation module 32, and a surface-free module 6 arranged outside the flame-retardant module 5.
[0038] In other words, the functional prefabricated wall is basically centered on the sound insulation module 1, with two layers of pipeline integration modules 21 and 22, two layers of thermal insulation modules 31 and 32 symmetrically arranged on both sides. Then, a waterproof module 4, a flame-retardant module 5, and a surface-free module 6 are arranged on the outside of the two layers of thermal insulation modules 31 and 32.
[0039] Generally speaking, when using this functional prefabricated wall system, the waterproof module 4 faces inwards, while the unfinished module 6 faces outwards.
[0040] Specifically, the sound insulation module 1, the first pipeline integration module 21, the second pipeline integration module 22, the first thermal insulation module 31, the second thermal insulation module 32, the waterproof module 4, the flame retardant module 5, and the unfinished module 6 all use bamboo oriented strand board as the main material; and the board thickness is 15 mm, thus forming a functional prefabricated wall with a total thickness of 110 mm to 120 mm.
[0041] Furthermore, the aforementioned bamboo oriented strand board has the following performance parameters: density of 0.9 g / cm³. 3 ~1.1 g / cm 3 The static bending strength is 75 MPa~95 MPa, the elastic modulus is 9000 MPa~11000 MPa, and the internal bond strength is 1.5 MPa~2.0 MPa. Generally, the above performance parameters of bamboo oriented strand board may vary slightly due to differences in adhesive application and thickness.
[0042] The preparation of the bamboo oriented strand board (OSB) varies slightly depending on the location of the different functional modules. In the OSB used to form the unfinished module 6, PF is used as the organic adhesive; this structural layer faces outwards to provide superior weather resistance. In contrast, in the OSB used to form the waterproof module 4, pMDI is used as the organic adhesive, ensuring that the formaldehyde release of this inward-facing functional module does not exceed 0.025 mg / cm³. 3 It has reached the ENF level.
[0043] For the remaining components located in the middle—sound insulation module 1, first pipeline integration module 21, first thermal insulation module 31, second pipeline integration module 22, second thermal insulation module 32, and flame retardant module 5—the bamboo oriented strand board used does not require special limitation on the type of organic adhesive. In this embodiment, pMDI is used as the organic adhesive in the bamboo oriented strand board of each of the aforementioned intermediate functional modules.
[0044] Specifically, refer to Figure 2 As shown, the sound insulation module 1 is formed by a second receiving frame 11 and sound insulation material 12 filled inside the second receiving frame 11.
[0045] Generally, the second receiving frame 11 is formed by uniformly opening regular holes that penetrate the thickness direction of the bamboo oriented strand board. In this embodiment, these holes are square in shape, and the total area of the holes accounts for about 85% of the total area of the bamboo oriented strand board.
[0046] In this embodiment, the sound insulation material 12 filled into the second receiving frame 11 is specifically glass wool.
[0047] Reference Figure 3 and Figure 4As shown, the first pipeline integration module 21 has an internal pipeline integration channel 211 and a prefabricated socket and switch channel 212 formed on the surface of the first pipeline integration module 21. The shape of the pipeline integration channel 211 is designed according to a general pipeline layout, while the prefabricated socket and switch channel 212 is used to install sockets and switches when this functional prefabricated wall is applied. The second pipeline integration module 22 has the same structure as the first pipeline integration module 21.
[0048] The first insulation module 31 and the second insulation module 32 are completely identical and have a similar structure to the sound insulation module 1. See details... Figure 5 As shown, the first insulation module 31 is formed by a first receiving frame 311 and insulation material 312 filled inside the first receiving frame 311.
[0049] The first receiving frame 311 is formed in a similar manner to the second receiving frame 11, both involving the uniform opening of regular holes penetrating the thickness direction of the corresponding bamboo oriented strand board. In this embodiment, the first receiving frame 311 and the second receiving frame 11 are completely identical to maximize the simplification of their manufacturing process and improve production efficiency.
[0050] In this embodiment, the insulation material 312 filled into the first receiving frame 311 is specifically mineral wool.
[0051] In this embodiment, the waterproof module 4 is formed by adding 1.0% to 1.5% of a waterproofing agent by weight of the bamboo oriented strand board (OSB). The flame-retardant module 5 is formed by adding 1.0% to 1.5% of a flame-retardant by weight of the bamboo OSB. Both the waterproofing agent and the flame-retardant are commercially available conventional functional additives. Generally, during the manufacturing process of conventional bamboo OSB, waterproofing agents and flame-retardant agents are added to improve its waterproof and flame-retardant properties; that is, the cost of using commercially available, mature bamboo OSB with corresponding waterproof and flame-retardant properties for the waterproof module 4 and flame-retardant module 5 is also acceptable.
[0052] The unfinished module 6 is formed by adding a thin layer of bamboo shavings (0.3 mm to 0.5 mm thick) to the surface during the manufacturing process of bamboo oriented strand board, in order to ensure that the functional module has a higher flatness.
[0053] Generally, for the above-mentioned functional prefabricated wall, after each functional module is formed, the surface is first sanded to a fixed thickness using 60-100 grit sandpaper; then the surface is treated with cold plasma, generally using N2-RF cold plasma treatment, with a treatment power of 200 W-300 W and a treatment time of 1 min-2 min; finally, the functional modules are cold-pressed together.
[0054] In this way, the functional prefabricated wall integrates the functions required of a wall material, such as waterproofing, flame retardancy, heat insulation, and sound insulation; the two-layer pipeline integration modules 21 and 22 provide ample space for pipeline laying; and the unfinished module 6 provides a more beautiful and flat exterior finish, avoiding the need for separate finishing, which would increase construction difficulty and cost.
[0055] Example 2
[0056] The functional prefabricated wall provided in this embodiment involves a window area, and therefore has a through-type window module in the thickness direction of the functional prefabricated wall.
[0057] The remaining structure of this functional prefabricated wall is the same as that in Example 1, and will not be described again in this example.
[0058] like Figure 6 As shown, to accommodate the window module, the functional prefabricated wall has a window 7a in the thickness direction. Combined with... Figure 7 and Figure 8 The specific structure of the window module 7 includes two window fixing side plates 71 that are fitted into the inner edge of the window 7a, and window material 72 that is fitted into the two window fixing side plates 71.
[0059] Generally, the window fixing side panel 71 is concave to more securely fit into the window 7a. The window material 72 is usually pressed between the two window fixing side panels 71 by cold pressing and gluing.
[0060] In this embodiment, the window material 72 is specifically glass.
[0061] Thus, the functional prefabricated wall provided in this embodiment, having a window module 7, is suitable for areas where windows need to be installed; and its basic structure is consistent with other pure wall parts, allowing for full assembly and application.
[0062] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
