Description

Technical Field

[0001] The utility model relates to the technical field of bamboo bricks, in particular to a hollow structure bamboo. Background Art

[0002] In the patent with the expired application number CN201020673304.1, a bamboo cylinder sandwich bamboo-wood composite wall is disclosed, which includes inner wall panels, outer wall panels, standard bamboo cylinders and wall frame, and is characterized in that the interior of the wall frame is a cavity structure, the inner wall panels and the outer wall panels are respectively arranged on both sides of the wall frame, and the standard bamboo cylinders are arranged in the cavity structure. The bamboo cylinder sandwich bamboo-wood composite wall provided by the utility model has the following advantages: the axial compressive strength and shear strength of bamboo are very high, the wall strength-to-weight ratio is high, the bamboo-wood composite frame structure and the vertical filling arrangement of the bamboo cylinder greatly enhance the vertical load capacity, lateral force resistance and impact resistance of the wall, thereby improving the overall applicability of the building in typhoon-resistant and earthquake-resistant areas, and the bamboo green part of the outer wall of the bamboo cylinder has excellent natural water resistance, and has a water vapor protection effect when sandwiched between the wall panels.

[0003] On the basis of the above patents, the Chinese invention patent with application number CN201410837591.8, entitled "Porous bamboo composite rectangular structural member and preparation method", discloses a porous bamboo composite rectangular structural member and preparation method, wherein the gap between the rectangular tube and the hollow native bamboo tube is filled with biomass filler or a mixture of biomass filler and plastic crushed material. Thus, it has the following advantages: wide selection of materials, convenient production, this kind of building component has the advantages of light weight, high rigidity, good ductility, strong self-recovery ability, good economic performance, superior seismic performance, etc., and can be applied to compression or bending components in the field of civil engineering structures.

[0004] In the above two schemes, whether it is the "surrounding panels + bamboo tubes + fillers" scheme disclosed in CN201020673304.1, or the bamboo tube fixing innovation added by CN201410837591.8 on the basis of CN201020673304.1, neither of them indicates the direction of the actual application of "surrounding panels + bamboo tubes + fillers" (such as brick and board products). In particular, the brick and board products based on "surrounding panels + bamboo tubes + fillers" lack innovation in combination and assembly, which makes them have innovative advantages over existing brick and board products.

[0005] The above scheme lacks innovation in practical application and combined assembly, resulting in the fact that although the CN201020673304.1 scheme has been made public for 14 years, there is still no application product of "surrounding panels + bamboo tubes + fillers" on the market.

[0006] Therefore, a large amount of reliance on chemical adhesives in combined construction increases the construction cost and also pollutes the environment due to the harmful substances that may be contained in the adhesives. The combination method that relies on adhesives limits the detachability and reusability of building materials. Once the building needs to be renovated or demolished, these materials are often difficult to be recycled, thus generating a large amount of construction waste. Traditional bamboo bricks and bamboo boards have great problems in bearing capacity, which limits the application of bamboo boards in load-bearing walls or floor structures. Although bamboo itself has good strength and flexibility, its application scope in construction is limited without proper reinforcement, and the potential of bamboo cannot be fully utilized.

[0007] In order to solve the problem that the solution of CN201020673304.1 "surrounding panels + bamboo tube + filler" is still insufficient in terms of specific products and assembly and fixation, the utility model proposes a new type of hollow structural bamboo material. Utility Model Content

The shapes of the alignment protrusion and the alignment groove can be adapted and snap-fitted to form a hollow structural bamboo assembly brick.

[0013] In a feasible implementation manner, the two end faces where the protrusion and the docking groove are arranged are respectively on the end faces of the hollow large bamboo tube and the hollow small bamboo tube in the length direction, and the alignment protrusion includes a bamboo tube structure and a filler.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figures 1 to 6 The utility model provides a technical solution: a hollow structure bamboo material, comprising: a hollow structure bamboo material square brick 1, an assembly structure and a fixing structure; wherein the hollow structure bamboo material square brick 1 comprises: a hollow large bamboo tube 1-3, a hollow small bamboo tube 1-4, surrounding panels 1-1, a filler 1-2 and an assembly structure; the hollow large bamboo tube 1-3 and the hollow small bamboo tube 1-4 are natural bamboos with cavities, the hollow large bamboo tube 1-3 and the hollow small bamboo tube 1-4 have a natural bamboo cavity structure, and a plurality of hollow large bamboo tubes 1-3 and hollow small bamboo tubes 1-4 are arranged in parallel; four The surrounding plate 1-1 is composed of multiple plates, which are used to enclose multiple large hollow bamboo tubes 1-3, small hollow bamboo tubes 1-4 and fillers 1-2 in a rectangular space formed by the multiple plates to form a brick-shaped or plate-shaped profile; the fillers 1-2 are used to fill the gaps between the surrounding plates 1-1 and the bamboo tubes; the assembly structure is arranged on the end face of each hollow structure bamboo square brick 1, which is used for limiting the assembly of adjacent hollow structure bamboo square bricks 1; the fixing structure is set inside each hollow structure bamboo square brick 1, which is used to fix the multiple hollow structure bamboo square bricks 1 after assembly.

[0025] In the specific implementation process, it should be noted that in the process of manufacturing hollow structural bamboo, bamboo with natural cavity is selected as raw material. The bamboo is divided into two types: hollow large bamboo tubes 1-3 and hollow small bamboo tubes 1-4. They are placed in a predetermined parallel layout to ensure the uniformity and strength of the structure. Then, a surrounding panel 1-1 composed of multiple sheets of board material is used to wrap the parallel arranged hollow large bamboo tubes 1-3, hollow small bamboo tubes 1-4 and fillers 1-2 in a rectangular space to form a hollow structural bamboo square brick 1 or a hollow structural bamboo board 3. The filler 1-2 is used to fill the gap between the surrounding panels 1-1 and the bamboo tube. The filler 1-2 can be a mixture of bamboo chips, wood powder, stone powder and adhesive, which is cured after filling / compacting; in an optimized design, the filler 1-2 can also be a foaming curing agent to increase the density of the hollow structural bamboo square brick 1.

[0026] In order to facilitate the connection and assembly between the hollow structure bamboo square bricks 1, an assembly structure is arranged on the end surface of each hollow structure bamboo square brick 1, so that the adjacent hollow structure bamboo square bricks 1 can be accurately limited and assembled. By setting the fixing structure inside each hollow structure bamboo square brick 1, the assembled multiple hollow structure bamboo square bricks 1 can be effectively fixed. This device makes full use of the natural characteristics of bamboo. Through the above layout, a new type of building material that is both beautiful and practical is manufactured. In addition, by increasing the height or length of the hollow large bamboo tubes 1-3, the hollow small bamboo tubes 1-4, the surrounding panels 1-1, the filler 1-2 and the assembly structure, a hollow structure bamboo board 3 (such as Figure 3 As shown), the surface area of ​​the hollow structural bamboo board 3 is larger than that of the hollow structural bamboo square brick 1, so as to meet the use requirements of different environments.

[0027] In some examples, further, the fibers of the surrounding panels 1-1 are horizontally oriented, and the fibers of the surrounding panels 1-1 are perpendicular to the bamboo fibers in the hollow large bamboo tube 1-3 and the hollow small bamboo tube 1-4, so as to enhance the strength in both horizontal and vertical directions.

[0028] In the specific implementation process, it should be noted that by configuring the orientation of bamboo fibers in the surrounding panels 1-1 and the hollow large bamboo tubes 1-3 and the hollow small bamboo tubes 1-4, the strength of the hollow structural bamboo in both horizontal and vertical directions is enhanced. The bamboo fibers in the hollow large bamboo tubes 1-3 and the hollow small bamboo tubes 1-4 are naturally arranged along the length direction of the bamboo tubes (i.e., the vertical direction). The fiber orientation in the surrounding panels 1-1 forms a vertical relationship with the fiber orientation of the bamboo tubes, i.e., the fibers of the fixed panels are arranged in the horizontal direction. The two types of bamboo tubes and the filler 1-2 are enclosed together by the surrounding panels 1-1 to form the final hollow structural bamboo panels 3 and the hollow structural bamboo panels 3, which effectively improve the compression and bending resistance of the entire structure in two main directions.

[0029] In some examples, further, a plurality of groups of bamboo tube structures are arranged in the hollow structural bamboo square brick 1, and each group of bamboo tube structures includes a hollow large bamboo tube 1-3 and a plurality of hollow small bamboo tubes 1-4 arranged outside the hollow large bamboo tube 1-3.

[0030] In the specific implementation process, it should be noted that the hollow large bamboo tubes 1-3 will serve as the central part of each group of bamboo tube structures, while the small bamboo tubes are surrounded by the outside of the large bamboo tubes. The arrangement of the hollow small bamboo tubes 1-4 is to increase the overall strength of the square bricks, and also to utilize the natural hollow structure of bamboo to ensure the sound insulation, heat preservation and other properties of the product. The arrangement of the hollow large bamboo tubes 1-3 and the hollow small bamboo tubes 1-4 forms an evenly distributed bamboo tube combination structure to ensure the balance and structural integrity of the square bricks, so that the hollow structure bamboo square brick 1 has good structural strength while maintaining lightness.

[0031] In some examples, further, the assembly structure includes an alignment protrusion 2-1 provided on one end surface of the hollow structural bamboo square brick 1, and an alignment groove 2-2 provided on the other end surface of the hollow structural bamboo. The shapes of the alignment protrusion 2-1 and the alignment groove 2-2 can be adapted to be snap-fitted to form a hollow structural bamboo assembly brick 2.

[0032] In the specific implementation process, it should be noted that the end surface of the hollow structure bamboo square brick 1 is provided with a positioning protrusion 2-1 and a positioning groove 2-2, so that the hollow structure bamboo square bricks 1 can be accurately and firmly connected and assembled. The shape and size of the positioning protrusion 2-1 and the positioning groove 2-2 are completely matched, ensuring seamless connection and tight connection during assembly, and having sufficient structural stability and bearing capacity after connection, realizing the fast, simple and stable modular assembly of the hollow structure bamboo square brick 1, improving the efficiency and flexibility in the construction or decoration process, and the hollow structure bamboo square brick 1 forms a hollow structure bamboo square brick group 4 (such as a triangle) in the shape of a triangle through the mutual matching of the positioning protrusion 2-1 and the positioning groove 2-2. Figure 4 As shown in the figure), the herringbone assembly method can effectively improve the stability and load-bearing capacity of the overall structure by increasing the contact area and dispersing the load. When a hollow structural bamboo square brick 1 on the upper layer is located in the middle of two hollow structural bamboo square bricks 1 on the lower layer, it helps to balance and disperse the weight of the upper layer, reduce the pressure on a single point, and thus improve the overall stability.

[0033] In some examples, further, the two end faces where the protrusions and the docking grooves are arranged are respectively on the two end faces of the hollow large bamboo tube 1-3 and the hollow small bamboo tube 1-4 pointing in the length direction, and the alignment protrusion 2-1 includes a bamboo tube structure and a filler 1-2.

[0034] In the specific implementation process, it should be noted that the hollow large bamboo tube 1-3 and the hollow small bamboo tube 1-4 constitute the main body of the hollow structural bamboo square brick 1. The alignment protrusion 2-1 includes a bamboo tube structure and a proper amount of filler 1-2 is added therein, and the filler 1-2 enhances the stability of the protrusion and improves the strength and durability of the entire connection structure.

[0035] In some examples, further, the fixing structure includes a plurality of vertical reinforcement pin holes 1-5, each of which is respectively penetrated through the filler 1-2. The vertical reinforcement pin holes 1-5 can be penetrated by fixing parts for reinforcing the hollow structural bamboo assembly bricks 2. When the hollow structural bamboo square bricks 1 are overlapped and combined, the vertical reinforcement pin holes 1-5 of the upper and lower layers can be aligned.

[0036] In the specific implementation process, it should be noted that the vertical reinforcement pin holes 1-5 enhance the overall stability and durability of the hollow structure bamboo square brick 1, and the vertical reinforcement pin holes 1-5 are evenly distributed inside the filler 1-2 to achieve the best reinforcement effect. Then, a fixing that can ensure durability and strength in the environment is inserted into each vertical reinforcement pin hole 1-5 to ensure that the fixing can fully penetrate and firmly fix inside the filler 1-2. The strength of the hollow structure bamboo square brick 1 in the vertical direction is further increased, and the overall structure is also made more stable and strong. Additional support and safety guarantees are provided for subsequent assembly and use. The hollow structure bamboo square brick 1 is made more solid and reliable when subjected to external pressure and impact, and its service life is extended, meeting the requirements of building materials for high strength and high stability. The fixing can be replaced with steel bars, and the hollow small bamboo tube 1-4 can be replaced with steel pipes to improve the overall strength.
