Description

Technical Field

[0001] This invention relates to the field of building structure technology, and more specifically, to a large-span timber structure that integrates mortise and tenon joints and woven timber, and a method for its construction. Background Technology

[0002] In existing technologies, the raised beam structure is one of the most widely used core structural systems in traditional Chinese wooden architecture. Its core is to transfer loads through layers of stacked beams. The conventional construction is to erect raised beams on top of columns, and set up short columns on the beams to support the upper short beams. In this way, the structure is raised layer by layer to form the load-bearing skeleton of the pitched roof. By adjusting the beam length and the height of the short columns, it can be flexibly adapted to different building spans and roof shapes. It is widely used in large official buildings such as palaces and temples as well as traditional residential buildings.

[0003] However, existing traditional beam-and-column structures have unavoidable technical bottlenecks: First, they have strict requirements for the specifications of the main materials. The main beams and columns need to use large-diameter, high-quality long timber, which places extremely high demands on the length, strength, and properties of the timber, resulting in high material costs. Moreover, natural large-diameter timber resources are becoming increasingly scarce, directly restricting the construction of large-scale timber structures. Second, they have poor flexibility in interior space, requiring dense columns to support multi-layer beam frames. The column spacing is limited by the beam span limit, making it difficult to form large-span, column-free interior spaces. Therefore, a technical solution is needed to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art, to form a large-span arched structure by splicing standardized small structural strips, and to realize a large-span column-free indoor space by using an arched force system with arched components. This invention provides a large-span wooden structure and construction method that integrates mortise and tenon joints and woven wood.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] This invention discloses a large-span timber structure integrating mortise and tenon joints and woven timber, comprising load-bearing components, arched components, roof beam components, and roof components. Two load-bearing components are provided, spaced apart. The arched components include multiple arch frames, spaced apart along the length of the load-bearing components. The middle of each arch frame protrudes upwards into an arch shape, and both ends of each arch frame are fixedly connected to the load-bearing components. The arch frames are constructed using a woven timber method. The roof beam components are fixedly mounted above the arched components and are constructed using a mortise and tenon joint. The roof components are installed above the roof beam components and the load-bearing components.

[0007] Furthermore, the load-bearing component includes vertical columns, a first ground beam, a second ground beam, and a first purlin. Adjacent vertical columns are connected by the first ground beam in the width direction of the load-bearing component, and adjacent vertical columns are connected by the second ground beam in the length direction of the load-bearing component. The upper end of the vertical column is inserted into the first purlin, and multiple first purlins are connected in series in a row along the length direction. The load-bearing component includes multiple rows of first purlins arranged in the width direction, and the end of the arch frame is inserted and fixed to the vertical column.

[0008] Furthermore, the connection point of two adjacent first purlins is located at the upper end of the vertical column, and the two adjacent first purlins are connected by a tenon block. The lower end face of the first purlin is provided with a first insert, and the upper end of the vertical column is provided with a first slot corresponding to the first insert.

[0009] Furthermore, the lengths of the vertical columns arranged along the width direction of the load-bearing components gradually decrease, with the longest vertical column being the one closest to another load-bearing component.

[0010] Furthermore, the arch frame includes two arch bars composed of multiple first, second, and third structural members and multiple crossbeams. The crossbeams connect the two arch bars, and the multiple crossbeams are arranged at intervals along the length of the arch frame. The first structural member includes three first slots, the second structural member includes three second slots, and the third structural member includes three third slots. The crossbeams passing through the first slots in the middle of the first structural member engage with the second slots at the ends of the second structural member and the third slots at the ends of the third structural member. The crossbeams passing through the second slots in the middle of the second structural member engage with the first slots at the ends of the first structural member and the third slots at the ends of the third structural member. The crossbeams passing through the third slots in the middle of the third structural member engage with the first slots at the ends of the first structural member and the second slots at the ends of the second structural member.

[0011] Furthermore, the first strip, the second strip, and the third strip are arranged sequentially and cyclically along the length of the arch strip, with the second strip and the third strip located on both sides of the first strip.

[0012] Furthermore, the opening direction of the first slot located in the middle of the first structural bar is opposite to that of the first slots located at both ends. The opening direction of the first slot is vertically upward or downward. The first slot is a rectangular slot. The crossbeam is a rectangular bar. The structure of the second and third structural bars is the same as that of the first structural bar.

[0013] Furthermore, the roof beam component includes multiple second purlins, multiple child columns, and multiple through beams. The multiple second purlins are mortised and tenoned together in a row. Each second purlin has two child columns at its lower ends. The lower ends of the child columns are inserted and fixed to the crossbeam. Multiple rows of second purlins are arranged along the length of the arch frame. The height of the second purlins gradually decreases from the middle to both sides along the length of the arch frame. The roof component includes multiple rafters. The multiple rafters are arranged at intervals along the length of the load-bearing component. The rafters are snapped into the second purlins to form a slope. The side of the second purlin is inserted and connected to the through beam. The through beam connected to the second purlin in the lower layer passes through the child columns supporting the second purlin in the upper layer.

[0014] Furthermore, the child column includes at least four vertical rods and four insert plates. Two vertical rods are connected to each other by two insert plates to form a group. Two insertion holes are opened on the side wall of the vertical rod along the length direction. The insert plates are partially inserted and fixed in the insertion holes. The two groups of vertical rods are spaced apart to allow the through beam to pass through. The lower end face of the second purlin is provided with a second insert bar. The lower end face of the second insert bar is provided with a third slot. The insert plate is provided with a fourth slot. The upper insert plate is inserted into the second insert bar through the third slot via the fourth slot. The upper end face of the crossbeam is provided with a second slot. The lower insert plate is inserted into the second slot of the crossbeam through the fourth slot.

[0015] This invention discloses a construction method for building the aforementioned large-span timber structure that integrates mortise and tenon joints and woven timber, comprising the following steps:

[0016] S1. Construct load-bearing components: Determine the distance between the two load-bearing components, splice the vertical column, the first ground beam, and the second ground beam, install the first purlin on the top of the vertical column and connect them through tenon joints;

[0017] S2. Constructing arched components: Insert the first structural members located at both ends of the arch frame into the vertical columns on the inner side of the load-bearing components, construct the crossbeams on the corresponding two first structural members, and construct the complete arch frame in sequence from bottom to top and from both ends to the middle.

[0018] S3. Constructing roof beam components: Construct the columns corresponding to the crossbeams from both ends of the arch frame, then connect the second purlins along the length direction, and construct them sequentially from top to top.

[0019] S4. Constructing roof components: Construct the ridge at the top of the second purlin, and lay the rafters along the slope formed by the second and first purlins.

[0020] The beneficial effects of this invention are:

[0021] This invention innovatively integrates woven timber arch components with mortise-and-tenon roof beam components. It employs an interlocking woven timber arch frame as the core load-bearing structure, using standardized small structural strips to form a large-span arch structure. This eliminates the need for large-diameter, high-quality long timber, significantly reducing material costs and reliance on natural timber resources. It breaks through the limitations of traditional structures on building volume. The arched load-bearing system of the arch components enables large-span, column-free interior spaces, completely solving the problems of dense columns and limited space division in traditional beam-and-tenon structures, greatly improving the flexibility of interior spaces. Furthermore, the mortise-and-tenon roof beams, connected by interlocking beams, form an integrated load-bearing system, which, combined with the interlocking structure of the woven timber arch, significantly improves the overall structural stability and seismic and lateral resistance performance, avoiding the problem of displacement and instability in traditional mortise-and-tenon joints. Standardized prefabricated components enable assembly-based construction, significantly reducing construction difficulty and improving construction efficiency. Attached Figure Description

[0031] The technical solutions in this embodiment 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.

[0032] Example 1:

[0033] like Figures 1 to 8 As shown, this embodiment discloses a large-span timber structure that integrates mortise and tenon joints and woven timber, including a load-bearing component 1, an arched component 2, a roof beam component 3, and a roof component 4.

[0034] like Figures 1 to 5 As shown, there are two load-bearing components 1, which are symmetrically arranged at intervals along the horizontal direction of the building to form the vertical support system on both sides of the building. The load-bearing components 1 are rectangular three-dimensional frame structures. The load-bearing components 1 include vertical columns 11, first ground beams 12, second ground beams 13, and first purlins 14. In this embodiment, the vertical columns 11 of the load-bearing components 1 are arranged in three rows at intervals in the horizontal direction of the building. In the width direction of the load-bearing components 1, adjacent vertical columns 11 are connected by first ground beams 12. Multiple first ground beams 12 are set from the bottom along the length direction of the vertical columns 11 to form a horizontal column support. In the length direction of the load-bearing components 1, adjacent vertical columns 11 are connected by second ground beams 13. Multiple second ground beams 13 are set from the bottom along the length direction of the vertical columns 11 to form a longitudinal stable column grid, forming a stable support structure on both sides of the building, providing stable bottom support for the large span of the building. Moreover, the load-bearing components 1 are constructed of small-diameter wooden strips, which are easy to obtain and do not require the use of large-diameter timber for load-bearing.

[0035] The upper end of the vertical column 11 is inserted into the first purlin 14. The lower end face of the first purlin 14 is integrally formed with the first insert 141. The upper end of the vertical column 11 is provided with a first slot 111 that corresponds to and fits the first insert 141. The first insert 141 is inserted into the first slot 111 to achieve precise positioning and anti-slip connection between the first purlin 14 and the vertical column 11. Multiple first purlins 14 are connected in series along the longitudinal direction of the building. The load-bearing component 1 includes multiple rows of first purlins 14 arranged along the transverse direction of the building. The end of the arch frame 21 is inserted and fixed to the vertical column 11 near the inner side of the building. The connection point of two adjacent first purlins 14 is located at the upper end of the vertical column 11. Two adjacent first purlins 14 are fixed by tenon joint 15 to ensure the connection strength and integrity of the longitudinal first purlins 14.

[0036] The length of the vertical columns 11 arranged along the width of the load-bearing component 1 gradually decreases from the inside to the outside of the building. The vertical column 11 closest to another load-bearing component 1 is the longest, so that the height of the three rows of first purlins 14 gradually decreases from the inside to the outside, adapting to the roof slope and forming a regular eaves structure. The three rows of first purlins 14 are, from high to low, the main purlin, the lower main purlin, and the eaves purlin, which serve as support for the lower edge slope of the building roof.

[0037] like Figure 3 , Figure 6 As shown, in this embodiment, the arched component 2 includes three arch frames 21. The three arch frames 21 are arranged at equal intervals along the length of the load-bearing component 1. The width between two adjacent arch frames 21 is less than or equal to the width of the arch frame 21, ensuring the load-bearing strength of the arched component 2 composed of the arch frames 21 as a whole. The middle part of the arch frame 21 protrudes upward to form an arch shape. The two ends of the arch frame 21 are fixedly connected to the load-bearing components 1 on both sides. The arch frame 21 is constructed by woven wood to form a large-span arched load-bearing main body.

[0038] The arch frame 21 includes two symmetrically spaced arches along the longitudinal direction of the building and multiple crossbeams 214. The two ends of each crossbeam 214 are fixedly connected to the two arches. The multiple crossbeams 214 are evenly spaced along the arc length of the arch frame 21, forming a stable arched truss structure. Each arch is formed by cyclically splicing multiple first slats 211, second slats 212, and third slats 213. The first slat 211 has three first slots 2111, the second slat 212 has three second slots 2121, and the third slat 213 has three third slots 2131. The opening direction of the first slot 2111 located in the middle of the first slat 211 is opposite to that of the first slots 2111 located at both ends. The crossbeam 214 is vertically oriented upwards or downwards to ensure that the crossbeam 214 and the structural bar form an interlocking structure after being snapped together, preventing it from loosening under load. The first slot 2111 is a rectangular slot, and the crossbeam 214 is a rectangular bar that fits the rectangular slot, ensuring that the crossbeam 214 will not rotate or loosen. The slot structures of the second structural bar 212 and the third structural bar 213 are completely consistent with those of the first structural bar 211. The opening angles of the first slot 2111, the second slot 2121, and the third slot 2131 on the corresponding structural bar are calculated based on the length and curvature of the arch bar, and need to be determined by calculation through the simulation construction of the entire arch bar. The first structural bar 211 at both ends has only two first slots 2111 to ensure the structural strength of the part connected to the load-bearing component 1.

[0039] The first structural member 211, the second structural member 212, and the third structural member 213 are arranged cyclically along the arc length of the arch in the order of "first structural member 211-second structural member 212-third structural member 213". The second structural member 212 and the third structural member 213 are located on the inner and outer sides of the arc of the first structural member 211, forming a continuous and smooth arch profile, ensuring the continuity of the force on the arch. The first structural member 211, the second structural member 212, and the third structural member 213 form a mutually locking structure through the crossbeam 214. The widths of the first slot 2111, the second slot 2121, and the third slot 2131 are adapted to the width of the crossbeam 214. 11. The width of the second slot 2121 and the third slot 2131 is equal to the width of the crossbeam 214 minus 0.2 to 0.5 mm, ensuring a tight and secure interference fit. The depth of the first slot 2111, the second slot 2121, and the third slot 2131 is not less than half the height of the section of the corresponding structural member and not more than two-thirds of the height of the section of the corresponding structural member, balancing the interlocking strength of the slots with the load-bearing capacity of the structural member itself, and avoiding excessive weakening of the section. The length of the depth of the first slot 2111, the second slot 2121, and the third slot 2131 is consistent with the thickness of the crossbeam 214, ensuring that the crossbeam 214 is completely inserted into the slot without any protrusion or misalignment.

[0040] The specific engagement relationship between the first structural member 211, the second structural member 212, the third structural member 213, and the crossbeam 214 is as follows: the crossbeam 214 passes through the first slot 2111 in the middle of the first structural member 211, and is simultaneously engaged and fixed with the second slot 2121 at the end of the second structural member 212 and the third slot 2131 at the end of the third structural member 213; the crossbeam 214 passes through the second slot 2121 in the middle of the second structural member 212, and is simultaneously engaged and fixed with the first slot 2111 at the end of the first structural member 211 and the third slot 2131 at the end of the third structural member 213; the crossbeam 214 passes through the third slot 2131 in the middle of the third structural member 213, and is simultaneously engaged and fixed with... The first slot 2111 at the end of the first structural member 211 and the second slot 2121 at the end of the second structural member 212 are engaged and fixed. Through the interlocking structure of the first structural member 211, the second structural member 212, the third structural member 213 and the crossbeam 214, the first structural member 211, the second structural member 212, the third structural member 213 and the crossbeam 214 form an integral load-bearing system, which evenly distributes the vertical load to the entire arch frame 21 and then transfers it to the load-bearing members 1 on both sides. Large span load-bearing can be achieved without large-diameter whole timber, solving the problem of dependence on huge timber resources in traditional beam-lifting structures, ensuring the spaciousness of the building's interior space, and preventing the situation of columns dividing the space.

[0041] like Figure 1 , Figure 2 , Figure 7 , Figure 8 As shown, the roof beam component 3 is fixedly mounted above the arched component 2. The roof beam component 3 is constructed using a mortise and tenon joint method, forming the load-bearing framework of the pitched roof. The roof beam component 3 includes multiple second purlins 31, multiple pedestals 32, and multiple through beams 33. The multiple second purlins 31 are tenoned together in a row along the longitudinal direction of the building, forming a longitudinally continuous purlin system. The lower ends of each second purlin 31 are supported by two pedestals 32. The lower ends of the pedestals 32 are inserted and fixed to the crossbeams 214 of the arch frame 21, realizing the second purlin... The second purlin 31 and the arched member 2 provide stable force transmission. The side of the second purlin 31 is connected to the through beam 33. The through beam 33, which is connected to the second purlin 31 in the lower layer, passes horizontally through the child column 32 supporting the upper second purlin 31, forming a through-beam load-bearing structure. The child columns 32 and the second purlin 31 of each layer are connected in series through the through beam 33 to form a whole, which greatly improves the longitudinal stability and lateral resistance of the roof truss. Stable support of the pitched roof can be achieved without dense indoor columns, freeing up large-span column-free indoor space.

[0042] The column 32 includes at least four vertical rods 321 and four insert plates 322. Two vertical rods 321 are connected to each other by two insert plates 322 to form a stable lattice column structure. The side wall of the vertical rod 321 has two parallel insertion holes 3211 along its length. The side part of the insert plate 322 is inserted and fixed in the insertion hole 3211 to achieve a stable connection between the vertical rod 321 and the insert plate 322. The two sets of vertical rods 321 are spaced apart along the longitudinal direction of the building, leaving a channel for the horizontal passage of the purlin 33 to adapt to the assembly requirements of the mortise and tenon structure.

[0043] The lower end face of the second purlin 31 is integrally formed with a second insert 311. The lower end face of the second insert 311 has a third slot 3111. The insert plate 322 has a fourth slot 3221. The upper insert plate 322 is fixed to the third slot 3111 of the second insert 311 by cross-insertion through the upper fourth slot 3221, so as to achieve precise positioning and stable connection between the child column 32 and the second purlin 31. The upper end face of the crossbeam 214 has a second slot 2141. The lower insert plate 322 is fixed to the second slot 2141 of the crossbeam 214 by cross-insertion through the lower fourth slot 3221, so as to achieve stable connection between the child column 32 and the arch frame 21, ensuring smooth transmission of vertical load. The upper and lower insert plates 322 have the same structure and can be used interchangeably by simply changing their direction.

[0044] The second purlin 31 is arranged in multiple rows along the transverse length of the building. The height of the multiple rows of second purlin 31 gradually decreases from the middle to both sides along the length of the arch frame 21. The lowest point is connected and matched with the height of the first purlin 14 of the load-bearing component 1 to form a continuous roof support slope.

[0045] The roof component 4 is installed above the roof beam component 3 and the load-bearing component 1. The roof component 4 includes multiple rafters 41, which are arranged at equal intervals along the longitudinal direction of the building. The upper end of the rafters 41 is connected to the ridge, and the lower end of the upper end of the rafters 41 extends and is fixed to the corresponding first purlins 14 on both sides of the building. The middle part of the rafters 41 is snapped and fixed to each row of second purlins 31 to form a complete pitched roof support structure. After the rafters 41 are laid, conventional enclosure structures such as sheathing, waterproofing layer, and roof finishing layer can be laid on top of them to complete the overall roof construction.

[0046] Example 2:

[0047] A construction method for constructing a large-span timber structure integrating mortise and tenon joints and woven timber as described in Embodiment 1 includes the following steps:

[0048] S1. Constructing load-bearing components: First, determine the lateral spacing between the two load-bearing components 1 according to the building design span. Level the construction site, lay out the lines, and dig and compact the pits for the pre-embedded depth of the load-bearing components 1. Determine the installation points of each vertical column 11. Vertically arrange the vertical columns 11 according to the design points. Connect and fix the horizontally adjacent vertical columns 11 with the first ground beam 12. Connect the vertically adjacent vertical columns 11 with the second ground beam 13 to form a stable column grid structure. Then, install the first purlin 14 on the top of the vertical column 11. Insert the first insert 141 at the lower end of the first purlin 14 into the first slot 111 at the upper end of the vertical column 11. Connect two adjacent first purlins 14 with tenon blocks 15 in series along the longitudinal direction to form a multi-row parallel first purlin 14 system. Complete the construction of the load-bearing components 1 on both sides. Backfill the pre-embedded pits to ensure the stability of the load-bearing components 1.

[0049] S2. Constructing Arch Component 2: Prefabricate standardized first structural members 211, second structural members 212, and third structural members 213, along with crossbeams 214, in the factory and transport them to the construction site; insert the first structural members 211 located at both ends of the arch frame 21 into the oblique slots of the vertical columns 11 inside the load-bearing component 1 to complete the end positioning of the arch frame 21; construct the crossbeams 214 at both ends into the corresponding slots of the two first structural members 211 on both sides of the arch frame, and then, in a top-down and from both ends of the arch frame 21 towards the middle order, install the first structural members 211 into the corresponding slots of the two first structural members 211 on both sides of the arch frame 21. The process involves a cycle of "1-second structural member 212-third structural member 213", where each structural member is sequentially connected to the crossbeam 214. During assembly, the lower ends of the structural members or crossbeams 214 need to be supported to prevent them from falling apart. Finally, the middle crossbeam 214 is inserted to complete the connection of the entire arch. The support for the crossbeam 214 is then removed, and the complete woven wooden arch is formed by interlocking the slots. Multiple crossbeams 214 connect two arches to form an integral arch frame 21. According to the design spacing, multiple arch frames 21 are erected sequentially along the longitudinal direction of the building to form an overall arch-shaped load-bearing system.

[0050] S3. Constructing roof beam components 3: Prefabricate the vertical rods 321 and insert plates 322 of the child columns 32, as well as the second purlins 31 and through beams 33; from both ends of the arch frame 21 towards the middle, construct child columns 32 correspondingly on each horizontal beam 214 of the arch frame 21, and insert and fix the insert plates 322 at the lower end of the child columns 32 to the second slots 2141 at the upper end of the horizontal beams 214; then, along the longitudinal direction of the building, mortise and tenon joint multiple sections of the second purlins 31 into a row, thus constructing the second purlins. The second insert 311 at the lower end of strip 31 is inserted and fixed to the insert plate 322 at the upper end of column 32, thus completing the installation of the single row of second purlins 31; according to the design height, the second purlins 31 of each row are erected sequentially from bottom to top, and at the same time, through beams 33 are installed between the second purlins 31 of adjacent rows, so that the through beams 33 pass horizontally through the reserved channels of the corresponding columns 32, connecting the columns 32 and the second purlins 31 of each layer into a mortise-and-tenon integrated roof truss system;

[0051] S4. Constructing Roof Components 4: Construct a ridge structure at the upper end of the second purlin 31 located at the top of the arch frame 21. Arrange multiple rafters 41 at equal intervals along the longitudinal direction of the building, with the upper ends of the rafters 41 overlapping and fixed to the ridge. The lower ends of the rafters 41 extend onto the first purlin 14, and the middle of the rafters 41 is correspondingly engaged and fixed with each row of second purlins 31 to form a complete roof support slope. Subsequently, lay the sheathing, waterproof underlayment, and roof finishing layer on top of the rafters 41 in sequence to complete the construction of the overall wooden structure.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of the present invention should also be considered within the scope of protection of the present invention.
