Description
Technical Field
[0001] This invention relates to the field of building structure and prefabricated construction technology, and in particular to a modular, equally spaced triangular roof beam frame structure based on integrated bamboo and its assembly method, which is suitable for the rapid construction of ecologically sensitive areas, temporary buildings and reusable building structures. Background Technology
[0002] Currently, prefabricated mortise and tenon joints and composite connection methods have been proven to improve resistance and facilitate deployment in traditional wood and bamboo structures. However, traditional bamboo and wood structures have the following drawbacks: simple mortise and tenon or binding connections are prone to loosening, their earthquake and wind resistance is insufficient, the structure is fixed, and the space scale cannot be flexibly adjusted according to needs. When encountering larger structures, there are problems such as inconvenience in transporting and unloading large-sized components, and a lack of flexible modular expansion functions.
[0003] Meanwhile, in ecologically sensitive areas such as forest trails and nature reserves, traditional building materials such as reinforced concrete cause significant environmental disturbance, have long construction cycles, and are difficult to assemble, disassemble, and reuse quickly. Although prefabricated bamboo structures can improve the factory prefabrication rate, they still have problems such as insufficient standardization of nodes, limited efficiency in rapid positioning and disassembly between modules, unclear upper limits on the spacing of the main module units arranged at equal intervals while meeting deflection and load-bearing capacity requirements, and difficulty in balancing economy and safety.
[0004] Therefore, there is an urgent need for a modular, equally spaced triangular roof beam frame structure based on integrated bamboo and its assembly method. Through its rapid assembly and stacking expansion capabilities, it can effectively solve the problems of traditional bamboo and wood structures being non-disassembly, difficult to transport, and lacking stability. Furthermore, it can combine structural calculations to determine the reasonable spacing and limit values of the equally spaced arrangement. Summary of the Invention

[0036] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0037] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0038] Reference Figures 1-6 This invention provides a modular, equally spaced triangular roof beam frame structure based on integrated bamboo, including a square steel foundation beam 1. Multiple triangular main units are arranged on the top surface of the square steel foundation beam 1, with equal spacing between the multiple triangular main units. Each triangular main unit includes a ground beam 11. One end of the ground beam 11 is detachably connected to a first inclined beam 2, and the other end of the ground beam 11 is detachably connected to a second inclined beam 3. The ends of the first inclined beam 2 and the second inclined beam 3 furthest from the ground beam 11 are detachably connected. The first inclined beam 2, the second inclined beam 3, and the ground beam 11 are arranged in a triangular structure. The triangular load-bearing units form a geometrically invariant system, improving overall stability and lateral stiffness.
[0039] The ends of the first inclined beam 2 and the second inclined beam 3 away from the ground beam 11 are detachably connected to a connecting beam 6 via a first connector 4; the connecting beam 6 demonstrates the performance of stacked expansion, achieving linear area growth.
[0040] The two ends of the ground beam 11 are detachably connected to the square steel foundation beam 1, the first inclined beam 2, and the second inclined beam 3 respectively through the second connector 5; the first connector 4 and the second connector 5 enable quick installation and disassembly, which is convenient for transportation.
[0041] The first inclined beam 2, the second inclined beam 3, the connecting beam 6, and the ground beam 11 are made of engineered bamboo. By using standardized bamboo, it is easy to prefabricate in the factory, assemble quickly on site, and disassemble and reuse.
[0042] The joints of the first connector 4 and the second connector 5 adopt a composite connection method of mortise and tenon positioning and bolt locking, which takes into account both rapid positioning and reliable force transmission, improves disassembly and assembly efficiency and reduces the risk of joint loosening.
[0043] This invention utilizes engineered bamboo for the first inclined beam 2, the second inclined beam 3, the connecting beam 6, and the ground beam 11. Meanwhile, the square steel foundation beam 1 is made of multiple hollow square steel bars. Through the first connector 4 and the second connector 5, the square steel foundation beam 1, the first inclined beam 2, the second inclined beam 3, the connecting beam 6, and the ground beam 11 can be quickly installed and disassembled. This not only improves the expansion performance but also effectively solves the problems of traditional bamboo and wood structures being non-removable, difficult to transport, and lacking stability. Furthermore, it can combine structural calculations to determine the reasonable spacing and limit values of the equally spaced arrangement.
[0044] To further optimize the design, multiple triangular main body units are evenly spaced on the top surface of the square steel foundation beam 1. The even spacing is the center-to-center distance S between adjacent triangular main body units, which is preferably 1000, 1600, or 2000 mm. Structural calculations are used to determine reasonable values and upper limits for the evenly spaced center-to-center distance S, thereby improving material utilization efficiency while meeting control targets.
[0045] In a further optimized design, a first tenon 21 is provided at the end of the first inclined beam 2 away from the ground beam 11. The first tenon 21 is detachably connected to a first mortise 31. The first mortise 31 is provided at the end of the second inclined beam 3 away from the ground beam 11. The first tenon 21 and the first mortise 31 are interlocked.
[0046] By inserting the first tenon 21 into the first mortise 31, the first inclined beam 2 and the second inclined beam 3 can be connected. At the same time, the first tenon 21 and the first mortise 31 enable quick installation and disassembly.
[0047] In a further optimized design, the first inclined beam 2 and the second inclined beam 3 are respectively provided with a second tenon 112 at one end facing the ground beam 11. The second tenon 112 is detachably connected to a second mortise 111, and the second tenon 112 and the second mortise 111 are interlocked.
[0048] By inserting the second tenon 112 into the second mortise 111, the first inclined beam 2 and the second inclined beam 3 can be installed at both ends of the ground beam 11 respectively. At the same time, the second tenon 112 and the second mortise 111 enable quick installation and disassembly.
[0049] The design was further optimized so that the ground beam 11 is connected to the square steel foundation beam 1 via multiple first bolts. These multiple first bolts facilitate rapid installation and disassembly of the ground beam 11 and the square steel foundation beam 1.
[0050] In a further optimized design, the first connector 4 includes a V-shaped plate 43. A trapezoidal plate 41 is fixedly connected to the closed end of the V-shaped plate 43 near the side of the first inclined beam 2 and the second inclined beam 3. The trapezoidal plate 41 is connected to the first inclined beam 2 and the second inclined beam 3 respectively by multiple second bolts.
[0051] The trapezoidal plate 41 has symmetrical first through holes 42, and the two first through holes 42 correspond one-to-one with the first inclined beam 2 and the second inclined beam 3 respectively. By passing the second bolt through the first through hole 42, it is convenient to quickly install and disassemble the trapezoidal plate 41 with the first inclined beam 2 and the second inclined beam 3.
[0052] The scheme is further optimized so that the two wing plates at the opening end of the V-shaped plate 43 are connected to the connecting beam 6 by the third bolts, and the opening of the V-shaped plate 43 is adapted to the connecting beam 6.
[0053] The two wing plates at the open end of the V-shaped plate 43 are respectively provided with second through holes 44. By passing the third bolt through the second through holes 44, it is easy to quickly install and disassemble the V-shaped plate 43 and the connecting beam 6.
[0054] The design was further optimized so that the shape of the trapezoidal plate 41 is matched with that of the first inclined beam 2 and the second inclined beam 3 after they are connected. That is, the inclined side of the trapezoidal plate 41 is matched with the inclination angle of the first inclined beam 2 and the second inclined beam 3 after they are connected.
[0055] In a further optimized design, the second connector 5 includes symmetrically arranged right-angled plates 51, with a connecting plate 52 fixedly connected between the right-angled ends of the two right-angled plates 51; the connecting plate 52 enables the two right-angled plates 51 to be symmetrically arranged on both sides of the connecting plate 52.
[0056] One right-angled side of the connecting plate 52 at one end of the ground beam 11 is connected to the first inclined beam 2 and the ground beam 11 by multiple fourth bolts. One right-angled side of the connecting plate 52 at the other end of the ground beam 11 is connected to the second inclined beam 3 and the ground beam 11 by multiple fourth bolts. Two fourth through holes 54 are opened on one right-angled side of the connecting plate 52 at one end of the ground beam 11 and the other right-angled side of the connecting plate 52 at the other end of the ground beam 11. The fourth bolts pass through the fourth through holes 54 to facilitate quick installation and disassembly of the right-angled side of the connecting plate 52 at one end of the ground beam 11 to the first inclined beam 2 and the ground beam 11, and the right-angled side of the connecting plate 52 at the other end of the ground beam 11 to the second inclined beam 3 and the ground beam 11.
[0057] The other right-angled side of the connecting plate 52 is connected to the square steel foundation beam 1 by the fifth bolt; a fifth through hole 55 is opened on the other right-angled side of the connecting plate 52, and the fifth bolt passes through the fifth through hole 55 to facilitate the quick installation and disassembly of the connecting plate 52 and the square steel foundation beam 1.
[0058] The right-angle end of the connecting plate 52 is connected to the ground beam 11 by multiple sixth bolts; the right-angle end of the connecting plate 52 is provided with multiple third through holes 53, and the sixth bolts pass through the third through holes 53 to facilitate the quick installation and disassembly of the connecting plate 52 and the ground beam 11.
[0059] The connecting plate 52 is positioned above the ground beam 11 located between the first inclined beam 2 and the second inclined beam 3. This allows the second connecting piece 5 to be effectively installed on the ground beam 11 located between the first inclined beam 2 and the second inclined beam 3, facilitating the placement of the second connecting piece 5.
[0060] In a preferred embodiment, the integrated bamboo is selected from materials of strength grade BL110, and the design values are obtained by reducing the strength according to the outdoor environment, wind load, and usage conditions of bamboo structures: bending strength approximately 38.1 MPa, tensile strength parallel to the grain approximately 28.2 MPa, compressive strength parallel to the grain approximately 31.5 MPa, shear strength parallel to the grain approximately 3.5 MPa, and modulus of elasticity approximately 8500 MPa. The above values are only illustrative parameters, and actual engineering projects can be modified according to material testing and specifications.
[0061] The side beam has a rectangular cross-section with a width × height of 70 × 80 mm. When the center distance S is 1000 mm, the side length of the triangle in the middle beam cross-section is 113.72 mm. When the center distance S is 1600 mm or 2000 mm, the side length of the triangle in the middle beam cross-section is 127.14 mm.
[0062] The bolt diameter is 8mm; the thickness of the connecting plate of the first connector 4 is 6-8mm, and the thickness of the connecting plate of the second connector 5 is 8-10mm.
[0063] To further optimize the scheme, this embodiment establishes the correspondence between the center distance S and parameters such as the cross-section of the hypotenuse beam and the thickness of the connecting plate through structural calculations. Preferred control indicators include: the deflection of the hypotenuse beam under dead load is no greater than l / 250, the stress ratio is less than 1.0, and the in-plane slenderness ratio of the hypotenuse beam is no greater than 200. Under typical engineering conditions (e.g., roof slope approximately 60°, calculated length of the hypotenuse beam approximately 3500mm, roof dead load and wind load values according to specifications, and using BL110 design values reduced according to environmental conditions), the following equal-spacing selection scheme can be obtained (this invention is not limited to this):
[0064] Center distance S≈1000mm; the rectangular cross-section of the side beam can be taken as width×height=70×80mm, the side length of the equilateral triangle cross-section of the middle beam is 113.72mm; the bolt diameter can be taken as 8mm; the thickness of the top connecting plate can be taken as 6mm, and the thickness of the bottom connecting plate can be taken as 8mm.
[0065] Center distance S≈1600mm; the rectangular cross-section of the side beam can be taken as width×height=70×80mm, the side length of the equilateral triangle cross-section of the middle beam is 127.14mm; the bolt diameter can be taken as 8mm; the thickness of the top and bottom connecting plates can both be taken as 10mm.
[0066] Center distance S≈2000mm; the rectangular cross-section of the side beam can be taken as width×height=70×80mm, the side length of the equilateral triangle cross-section of the middle beam is 127.14mm; the bolt diameter can be taken as 8mm; the thickness of the top and bottom connecting plates can both be taken as 10mm.
[0067] Under the typical conditions described above, the center-to-center distance S of equal spacing can reach approximately 2000 mm and meet the deflection limit; further increasing the center-to-center distance S may lead to difficulties in meeting the deformation index. For different wind, snow, and earthquake parameters, roof panel stiffness, or construction methods in different regions, those skilled in the art can review and adjust the reasonable upper limit of the center-to-center distance S of equal spacing based on the selection criteria given in this specification.
