Description

Technical Field

[0001] This utility model relates to a building wall filling board and its mold, belonging to the technical field of prefabricated green building materials. Background Technology

[0002] The construction industry accounts for a significant portion of global energy consumption.

[0003] To improve the overall load-bearing capacity, environmental friendliness, and other comprehensive performance of walls, composite wall structures are gradually emerging, and green building materials have become an important 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. Existing technologies have led to the development of large-format wood, bamboo, and bamboo-wood composite wall systems. However, when bamboo-wood composite materials are used to construct large-format load-bearing walls, solid structures in the form of reconstituted wood, reconstituted bamboo, cross-laminated timber (CLT), or bamboo-wood composites are generally employed. While solid structures increase strength and load-bearing capacity, they also increase material usage and cost. For example, CLT is made by planing solid wood boards on all four sides and then gluing multiple layers together, resulting in a higher market price. When bamboo is made into large-format boards, it generally requires splitting the bamboo tubes or steaming them at high temperatures to flatten the bamboo walls, obtaining bamboo strips. Because the diameter and wall thickness of the bamboo root are large and the diameter and wall thickness are thin, the width and thickness of the bamboo strips differ significantly at both ends. This necessitates processing them to achieve the same thickness and width at both ends, resulting in significant waste of materials and labor costs. Therefore, bamboo plywood is more expensive than wood plywood. Reconstituted bamboo and wood require large amounts of adhesives and resins, with densities exceeding 1.2, leading to even higher prices. Furthermore, high density generally results in poorer insulation, requiring an additional insulation layer on the wall. More importantly, the processed bamboo strips, regardless of their combination, no longer possess the axial support strength of the original bamboo. If bamboo tubes or wooden pillars are directly arranged vertically and fixed together as load-bearing materials for load-bearing walls, it reduces the wall's weight while maintaining its load-bearing capacity and structural stability, increasing insulation, and reducing material usage and costs, making it an excellent choice. However, in actual use, in order to avoid the situation where adjacent bamboo tubes and wooden columns cannot share the load when the local load-bearing capacity is large, it is necessary to process the top and bottom ends of the bamboo tubes and wooden columns to be the same size, arrange the bamboo tubes and wooden columns in the frame, and ensure that the top and bottom ends of each bamboo tube and wooden column are in close contact with the top and bottom beams of the frame. In this way, the load-bearing capacity is evenly distributed to each adjacent bamboo tube and wooden column through the frame beams, which can improve the overall load-bearing capacity when the force is large.

[0004] However, in practice, because bamboo tubes grow naturally, their shape, curvature, and diameter cannot be exactly the same. Although the length of the bamboo tubes can be relatively consistent by clamping and fixing them in the middle while cutting both ends, it is difficult to ensure that each bamboo tube is fixed in the same position as when it was cut when placed in a frame with fixed length and width. Furthermore, when placing them into the frame, to ensure that the top and bottom ends of each bamboo tube and wooden column are in close contact with the upper and lower beams of the frame, the dimensions inside the frame must be exactly the same as the length of the bamboo tubes. This requires aligning the end faces of the bamboo tubes parallel to the frame beams before inserting or pressing them into the frame, which increases the difficulty of operation and reduces efficiency. If the bamboo tubes are arranged in rows and then the frame is assembled outside, each bamboo tube in the row needs to be fixed in the position it was in when it was cut, which is very difficult to achieve. All of these reasons combined limit its widespread application in the construction field.

[0005] Therefore, there is an urgent need to develop a new type of wall infill board that can reduce the weight of the wall while ensuring its load-bearing capacity and structural stability, increasing its thermal insulation, fixing bamboo tubes together to form a whole, and making it easy to saw off both ends of the bamboo tubes to form standard-sized wall infill boards. These boards can be used as partition walls or fixed in frames to serve as load-bearing walls, making them suitable for factory assembly line operations and easy to assemble, thus meeting the modern building's demand for wall panels that are high-efficiency, high-strength, low-carbon, environmentally friendly, and sustainable. Utility Model Content

[0006] This utility model addresses the shortcomings of existing technologies by providing a building wall filling board and its mold.

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0008] One of the purposes of this utility model is to provide a building wall filling board, which includes multiple bamboo tubes arranged in parallel, and a filling material is provided on the outside of the bamboo tubes. The overall shape of the filling material is square.

[0009] The beneficial effects of this utility model are as follows:

[0010] This invention uses multiple parallel bamboo tubes as the main structure, with the bamboo tubes retaining their natural hollow shape and nodes. Filling material is placed on the outside of the bamboo tubes, collectively forming a square-shaped wall filling panel. The hollow nature of the bamboo tubes significantly reduces the overall weight of the filling panel and increases the insulation effect, while the bamboo node structure and the vertical compressive strength of the bamboo ensure high support capacity, helping to improve the wall's load-bearing capacity and enhance its impact and bending resistance. This invention utilizes the high strength and load-bearing capacity of the bamboo tubes themselves, and uses the filling material to fix the bamboo tubes into a whole, enhancing the overall stability of the wall and improving its insulation performance.

[0011] After the filling board in this invention has cured and been demolded, the bamboo tubes and filling material are glued together to form a single unit. Then, the ends of the bamboo tubes are cut to standardized dimensions, producing filling boards of uniform size. These filling boards can be used directly as partition walls, or, through the use of beams, columns, and other frame components, to form a load-bearing wall with an "outer frame + inner filling board." This structure ensures that the end of each bamboo tube is in full contact with the upper and lower beams of the frame, thus distributing the load evenly across each bamboo tube and improving the overall load-bearing capacity.

[0012] The surface of the filler board after demolding can be further processed. By grinding or other processing on the surface of the filler board after demolding, functional surface layers such as fireproof boards, decorative boards, and load-bearing structural boards can be glued or nailed on, forming an integral whole with the frame structure to meet the corresponding fireproof and load-bearing application requirements.

[0013] Compared with traditional solid wall infill panels, this utility model effectively reduces the weight of the wall and lowers the amount of materials used and the cost.

[0014] Furthermore, bamboo tubes, as a renewable resource, help reduce carbon emissions, aligning with the green and low-carbon environmental protection concept. The structural design of this utility model's building wall infill panel is simple, facilitating factory assembly line operations and assembly, improving production efficiency, and meeting the modern building's demand for high-efficiency, high-strength, low-carbon, environmentally friendly, and sustainable wall panels.

[0015] Based on the above technical solution, the present invention can be further improved as follows:

[0016] Furthermore, the smaller diameter ends of adjacent bamboo tubes face opposite directions.

[0017] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: Due to the characteristics of bamboo growth, bamboo is generally shaped with a large diameter at the root (large diameter end) and a small diameter at the top (small diameter end). If the bamboo tubes are arranged in a longitudinal direction, the large diameter ends of adjacent bamboo tubes will contact or be close to each other, but the distance between the small diameter ends will be relatively far. This may cause the small diameter ends of the bamboo tubes to shift or bend. Due to the special structure of bamboo tubes, if the force on the bamboo tube is perpendicular, its multiple bamboo nodes can bear the weight and distribute the force well. However, if the top of the bamboo tube shifts or bends significantly, it may cause the force on the bamboo tube to shift. The change in orientation prevents the bamboo joints from functioning optimally under load, affecting load-bearing capacity. This invention addresses this by designing adjacent bamboo tubes with opposite orientations of their smaller diameter ends. This alternating arrangement of the larger and smaller diameter ends reduces the space for the smaller diameter ends to shift or bend under stress. This reduces the space required for internal filling material, saving costs, while also increasing the number of bamboo tubes and improving the load-bearing capacity of the bamboo tubes. Furthermore, it makes the gaps between the bamboo tubes more uniform, which is beneficial for improving the filling efficiency and density of the filling material, thereby further enhancing the overall stability and load-bearing capacity of the filling board.

[0018] Furthermore, the opposite surfaces of adjacent bamboo tubes are flattened.

[0019] The beneficial effects of adopting the above-mentioned further technical solutions are: after the opposite sides of the bamboo tubes are flattened, the surface of the bamboo tubes is smoother, which allows the bamboo tubes to be arranged more closely, increases the number of bamboo tubes, further improves the load-bearing capacity of the filling board, and also facilitates the tight bonding between the filling material and the bamboo tubes, thus improving the filling effect.

[0020] Furthermore, the bamboo tube array has one, two, or more rows.

[0021] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: When the filling board of this utility model is used as a filling material for the load-bearing walls of high-rise buildings, since the wall needs to have a high load-bearing capacity, if the strength of a single row of bamboo tubes cannot meet the required load-bearing capacity of the wall, the number of rows of bamboo tubes in the filling board can be adjusted according to actual needs, thereby flexibly controlling the size and load-bearing capacity of the filling board, and improving the thermal insulation effect. This design makes the building wall filling board of this utility model more suitable for building walls of different sizes and structures, improving its practicality and broadening its application range.

[0022] Furthermore, the filler material is an adhesive, aerogel, foam, or a fire-retardant polyurethane material with added flame retardants or flame-retardant materials.

[0023] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: Adhesives, aerogels, foaming agents, or fire-retardant polyurethane materials with added flame retardants or flame-retardant materials possess excellent adhesion and filling properties, enabling them to firmly bond the bamboo tubes together to form a unified structure. This improves the connection strength between the bamboo tubes within the filling material, restricts lateral displacement of the bamboo tubes under stress, and enhances the stability and load-bearing capacity of the filling board. Furthermore, the filling material also possesses certain thermal insulation properties, which helps improve the thermal insulation effect of the wall and enhances the practicality of this utility model's building wall filling board.

[0024] Furthermore, the filling material is a thermal insulation material.

[0025] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: using thermal insulation materials as filler materials can significantly improve the thermal insulation performance of walls, reduce energy consumption, and conform to the green and low-carbon environmental protection concept; thermal insulation materials can also effectively isolate external noise and improve the comfort of the living or working environment. In addition, the range of thermal insulation materials is wide, and selection can be made according to specific needs and cost considerations, increasing the flexibility and applicability of this utility model.

[0026] Furthermore, it also includes wooden pillars, which are arranged between the bamboo tubes and are parallel to the bamboo tubes.

[0027] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: by adding wooden columns between the bamboo tubes, the cross-sectional area and number of wooden columns can be adjusted according to the load-bearing capacity required by the filling board. Using large-section wooden columns as load-bearing structures between the bamboo tubes can improve the load-bearing capacity of the filling board without causing a significant increase in the weight of the filling board. Moreover, the vertical wooden columns can be connected to the frame beams of the frame through mortise and tenon joints, round wooden sticks or long wooden screws, which makes it easier to connect adjacent wall panels and floor slabs.

[0028] Furthermore, the wooden pillars are round logs, square logs, flat logs, planks, glued laminated timber, or bamboo-wood composite boards.

[0029] The second objective of this utility model is to provide a mold for a building wall filling board as described above, which includes a mold frame, a bottom template disposed below the mold frame, and an upper cover plate disposed above the mold frame.

[0030] The beneficial effects of the above-mentioned technical solution of this utility model are:

[0031] The mold structure of this utility model is reasonably designed. Through the cooperation of the mold frame, bottom template and top cover plate, bamboo tubes and filling materials can be easily formed into building wall filling boards of the required shape, which improves production efficiency and reduces manufacturing costs. In addition, the use of molds also helps to ensure the dimensional accuracy and shape consistency of the filling boards, thus improving product quality.

[0032] Furthermore, the upper cover plate is provided with multiple injection holes.

[0033] The beneficial effects of adopting the above-mentioned further technical solutions are as follows: by setting multiple injection holes in the upper cover plate, the filling material can be conveniently injected into the mold, thereby filling the bamboo tubes with the filling material, improving the filling efficiency. The upper cover plate also compresses the filling material, making the filling material more uniform and compact, thus improving the overall quality and performance of the filling plate. The design of multiple injection holes also allows the filling material to be evenly distributed around the bamboo tubes, ensuring the overall quality and performance of the filling plate. Furthermore, the injection position and amount of the filling material can be adjusted as needed, making the distribution of the filling material in the mold more reasonable.

[0034] Furthermore, the inner sides of the mold frame, the upper cover plate, and the bottom template are all provided with release templates.

[0035] The beneficial effects of adopting the above-mentioned further technical solutions are: the setting of the demolding template avoids the situation where the filling material sticks to the inner wall of the mold during the curing process. After the molding is completed, the molded filling plate can be easily removed from the mold, avoiding the adhesion between the filling plate and the mold, ensuring the integrity and surface quality of the filling plate, and improving the demolding efficiency.

[0036] The third objective of this utility model is to provide an application of the building wall filling board as described above, characterized in that it is used in the preparation of walls.

[0037] The beneficial effects of the above-mentioned technical solution of this utility model are:

[0038] This invention achieves rapid preparation of wall filling boards by combining bamboo tubes with filling materials and molding them using a mold. After demolding, the bamboo tubes and filling materials are glued together to form a single unit. Subsequently, the ends of the bamboo tubes are standardized and sawn to produce filling boards of uniform specifications. These filling boards can be used directly as partition walls or, through frame structures such as frame beams and columns, to form a load-bearing wall with an "outer frame + inner filling board." This structure ensures that both ends of each bamboo tube and wooden column are in close contact with the upper and lower beams of the frame, thus evenly distributing the load-bearing capacity to each bamboo or wooden piece and improving the overall load-bearing capacity.

[0039] Applying this type of filler board to wall construction not only meets the modern building's demand for wall panels that are high-efficiency, high-strength, low-carbon, environmentally friendly, and sustainable, but also provides a new solution for the field of green and environmentally friendly prefabricated buildings, promoting the development and application of green building materials.

Detailed Implementation

[0054] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0055] Example 1

[0056] See Figure 1A building wall filling board includes multiple bamboo tubes 101 arranged in parallel in a row. A filling material 102 is provided on the outer side of each bamboo tube 101, and the filling material 102 is square in shape. The opposite surfaces of adjacent bamboo tubes 101 are flattened.

[0057] The filler material 102 is an adhesive, aerogel, foam, or a fire-retardant polyurethane material with added flame retardants or flame-retardant materials. Alternatively, the filler material 102 is a thermal insulation material. In this embodiment, the filler material 102 is foam, which, in addition to providing good bonding strength, has a structure that improves the thermal insulation effect of the wall.

[0058] Example 2

[0059] See Figure 2 A building wall filling board, which differs from Embodiment 1 in that, in this embodiment, the smaller diameter ends 1011 of adjacent bamboo tubes 101 face opposite directions.

[0060] In this embodiment, the smaller diameter ends 1011 or larger diameter ends 1012 of adjacent bamboo tubes 101 face opposite directions. Due to the characteristics of bamboo growth, bamboo is generally shaped with a larger diameter at the root (larger diameter end 1012) and a smaller diameter at the top (smaller diameter end 1011) (see figure). If the bamboo tubes 101 are arranged in a longitudinal direction, the larger diameter ends 1012 of adjacent bamboo tubes 101 will be in contact or close to each other, but the distance between the smaller diameter ends 1011 will be relatively far. This may cause the smaller diameter ends 1011 of the bamboo tubes 101 to shift or bend. Due to the special structure of the bamboo tube 101, if the force on the bamboo tube 101 is perpendicular, its multiple bamboo nodes can bear the weight well and distribute the force. However, if the top of the bamboo tube 101 shifts significantly or bends, the force may be lost. When the curvature is large, it may cause a change in the direction of force on the bamboo tube 101, and the bamboo nodes will not be able to play their role when bearing weight, thus affecting the load-bearing effect. The present invention addresses this by having the small diameter ends 1011 of adjacent bamboo tubes 101 face opposite directions, so that the bamboo tubes 101 are arranged with alternating large diameter ends 1012 and small diameter ends 1011. This reduces the space for the small diameter ends 1011 of the bamboo tubes 101 to shift or bend when under force, thereby improving the load-bearing capacity of the bamboo tubes 101 of the present invention. At the same time, it makes the arrangement between adjacent bamboo tubes 101 more compact, thus allowing more bamboo tubes 101 to be arranged, increasing the number of bamboo tubes 101, and increasing the overall load-bearing capacity when a large load-bearing capacity is required.

[0061] Example 3

[0062] See Figure 3This is a building wall filling board. Unlike Embodiment 1, in this embodiment, the bamboo tubes 101 are arranged in two rows. The two rows of bamboo tubes 101 are staggered, that is, each bamboo tube 101 in one row is placed in the gap of the bamboo tubes 101 in the other row, so that the arrangement between the two rows of bamboo tubes 101 is more compact, which improves the load-bearing capacity of the wall and also improves the heat insulation effect.

[0063] Example 4

[0064] See Figure 4 This is a building wall filling board. Unlike Embodiment 2, in this embodiment, the bamboo tubes 101 are arranged in two rows. The two rows of bamboo tubes 101 are aligned, and the smaller diameter ends 1011 or larger diameter ends 1012 of adjacent bamboo tubes 101 in the two rows face opposite directions. Because the smaller diameter ends 1011 or larger diameter ends 1012 of the bamboo tubes 101 in the same row face opposite directions, when two or more rows of bamboo tubes 101 are arranged, the bamboo tubes 101 can be aligned, ensuring a tight arrangement between the two rows of bamboo tubes 101. This improves both the load-bearing capacity of the wall and the insulation effect.

[0065] Example 5

[0066] See Figure 12 A building wall filling board, which differs from Embodiment 2 in that this embodiment also includes wooden pillars 103, which are arranged between bamboo tubes 101, and are arranged parallel to the bamboo tubes 101, and are arranged alternately.

[0067] The wooden pillar 103 is made of square timber, round timber, flat timber strips, wood planks, glued laminated timber, or bamboo-wood composite board.

[0068] In this embodiment, the wooden post 103 is glued laminated timber.

[0069] Everything else is the same as in Example 2, and will not be repeated here.

[0070] Example 6

[0071] See Figure 13 A building wall filling board, which differs from embodiment 5 in that two or more bamboo tubes 101 are arranged continuously as a load-bearing structure, and a cavity is provided between adjacent load-bearing structures, and the wooden column 103 is placed in the cavity of the bamboo tube 101.

[0072] Everything else is the same as in Example 5, and will not be repeated here.

[0073] Example 7

[0074] See Figures 5-9A mold for a building wall infill panel according to any one of embodiments 1-6 includes a mold frame, a bottom template 402 disposed below the mold frame, and an upper cover plate 401 disposed above the mold frame. In this embodiment, the mold frame, the bottom template 402, and the upper cover plate 401 are connected by a pin 405, which is threadedly connected to the bottom template 402. Specifically, the mold frame includes a frame beam plate 403 and a frame column 404. The frame beam plate 403 and the frame column 404 are provided with through holes. The bottom template 402 is provided with corresponding threaded holes, and the upper cover plate 401 is provided with corresponding countersunk holes. By passing the pin 405 through the countersunk hole of the upper cover plate 401 and the through hole on the mold frame, and tightening it in the threaded hole on the bottom template 402, the mold frame, the upper cover plate 401, and the bottom template 402 are fixedly connected.

[0075] When assembling the mold, first place the bottom template 402 on the flat surface, then place the frame beam plate 403 and frame column 404 of the mold frame on the corresponding positions of the bottom template 402, and then place the top cover plate 401 on top. By screwing on the pin 405, the various parts of the mold are fixed.

[0076] There are two methods for filling the filler material 102. First, after assembling the bottom template 402 and the mold frame, arrange the bamboo tubes 101, pour the filler material 102 over them, and then place the top cover plate 401 on top. Tighten the pin 405 and wait for the filler material 102 to cure and bond tightly with the bamboo tubes 101. Alternatively, the top cover plate 401 has multiple injection holes 406. After assembling the bottom template 402 and the mold frame, arrange the bamboo tubes 101, place the top cover plate 401 on top, and inject the filler material 102 into the mold through the injection holes 406. Then, wait for the filler material 102 to cure and bond tightly with the bamboo tubes 101.

[0077] The inner sides of the mold frame, the upper cover plate 401, and the bottom template 402 are all provided with a release template 407. The release template 407 on the inner side of the upper cover plate 401 has a through hole corresponding to the injection hole 406. The release template 407 makes it difficult for the filler material 102 to stick to the mold after curing, making it easier to demold. This utility model does not limit the material of the release template 407, as long as the material of the release template 407 does not easily bond with the filler material 102. In this embodiment, the release template 407 is a nylon plate.

[0078] The process of using the mold for the building wall infill panel in this embodiment is as follows:

[0079] 1. Place the bottom template 402 on a horizontal surface, and then place the frame beam plate 403 and frame column 404 of the formwork frame on the corresponding positions of the bottom template 402. The bottom template 402 and the formwork frame are fixed with screws or rivets.

[0080] 2. Arrange the bamboo tubes 101 and / or wooden pillars 103 in sequence to make them tightly packed;

[0081] IV. There are two methods for filling with filler material 102:

[0082] ① After pouring or spraying the filler material 102, cover the top cover plate 401, tighten the pin 405, and wait for the filler material 102 to cure and be tightly bonded to the bamboo tube 101 and / or wooden column 103.

[0083] ② Cover the upper cover plate 401, tighten the pin 405, and inject the filling material 102 into the mold through the injection hole 406. Wait for the filling material 102 to solidify and be tightly bonded to the bamboo tube 101 and / or wooden column 103.

[0084] 5. After the filling material 102 has cured, open the top cover plate 401 and the mold frame, take out the filling board, and use a sawing device to saw the ends of the bamboo tubes 101 and / or wooden pillars 103 at both ends to make filling boards of uniform specifications.

[0085] Example 8

[0086] See Figures 10-11 A composite wall system includes a building wall infill panel as described in any of Embodiments 1-1, and further includes a panel 200 and a frame 300. Two panels 200 are provided, and the building wall infill panel is disposed between the two panels 200. The frame 300 is disposed around the infill panel. The panels 200 and the frame 300 are connected by mortise and tenon joints or fasteners. One, two, or more building wall infill panels are provided between the two panels 200. The above description is only a preferred embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
