Description

Technical Field

[0001] The present application relates to the technical field of building construction, and in particular to a woven wood dome that can adapt to a free-form surface. Background Art

[0002] As a typical mutual-supporting structure, the woven-beam arch is a woven-beam wooden arch bridge with the structural features of mutual support and locking between multiple components. Looking back at the history of ancient Eastern architecture, woven-beam wooden arch bridges were widely distributed in the Bianshui, Fujian and Zhejiang regions. The most popular example is the "Bianshui Rainbow Bridge" in "Along the River During the Qingming Festival". The ingenuity of "mutual support" in the Rainbow Bridge is to avoid the long-term impact of the turbulent Bianshui River on the bridge columns, as well as the reality of ships hitting the bridge columns and being destroyed from time to time, and thus formed an innovative structural exploration of "the bridge has no columns, all with huge wooden frames" in the large-span scene.

[0003] See also Figure 1 The mutual supporting frame structure of Hongqiao Bridge is composed of at least two groups of longitudinal arch frames, and the longitudinal arch frames are divided into the first arch frame 7 and the second arch frame 8. Among them, the first arch frame 7 is composed of three longitudinal beams of equal length; the second arch frame 8 is composed of four longitudinal beams of two long and two short. The two types of longitudinal arch frames fit together to form a longitudinal arch bridge structure, and the transverse beams 9 are inserted into the gap formed by the fit of the two, and the longitudinal beams are fixed to the transverse beams 9 with iron nails, so that the beams overlap and support each other, forming a morphological texture like a woven fabric. In this bridge system, the penetration of the crossbeam (transverse beam 9) into the longitudinal arch frame makes the two arch frames of different forms form a structural whole, so that the two can form mutual pressure, locking, mutual support, and uniform force. Specifically, the intersection nodes of two adjacent longitudinal beams in the first arch frame 7 are overlapped at the center of the longitudinal beams of the second arch frame 8 via crossbeams, and the material bending moment of the components in the second arch frame 8 is used to strengthen the node strength and overall structural strength of the first arch frame 7, and vice versa, that is, mutual support.

[0004] The ingenuity of the arch structure of a woven-beam timber arch bridge lies in the use of straight wood instead of curved wood, which is combined into a curved arch bridge by interlacing and pressing straight wood. However, a woven-beam timber arch bridge made of logs only has a curved surface in the length direction of the arch bridge. In other words, a woven-beam timber arch bridge is a mutually supported structure with a one-way curved surface. This makes the mutually supported structure of the woven-beam arch only applicable to curved arch bridges, and its applicability is greatly limited, which restricts its application in other buildings (such as house domes). Utility Model Content

[0005] In order to solve the above-mentioned problems, an embodiment of the present application provides a woven wood dome construction technology that can adapt to free-form surfaces. The woven wood dome has a mutually supporting configuration of bidirectional surfaces with positive curvature, which expands the adaptability of traditional mutually supporting configurations.

[0006] To this end, the following technical solutions are adopted in the embodiments of the present application:

[0007] An embodiment of the present application provides a woven wood dome that can adapt to a free-form surface, comprising: M first-configuration arch frames, wherein M is greater than or equal to 2; the first-configuration arch frames are arranged to extend as a whole along a first direction, and the M first-configuration arch frames are arranged in parallel along a second direction; the first-configuration arch frames include at least two cross-arranged first rods; N second-configuration arch frames, wherein N is greater than or equal to 2; the second-configuration arch frames are arranged to extend as a whole along a second direction, and the N second-configuration arch frames are arranged in parallel along the first direction; the second-configuration arch frames include at least two cross bars extending horizontally along the second direction, and two second rods are cross-connected on the cross bars; the cross bars are arranged on the first rods, and adjacent cross bars are connected to each other through the second rods; the first direction is the width direction of the woven wood dome, the second direction is the length direction of the woven wood dome, and the plane formed by the first direction and the second direction is a horizontal plane.

[0008] In this embodiment, by adopting the cross setting of multiple first configuration arch frames and second configuration arch frames, the woven wood dome can present a curved surface in both directions, so that the woven wood dome has a mutual support configuration of a bidirectional curved surface with positive curvature, and the mutual support structure is expanded from an arch bridge (two-dimensional arch curve) to a building volume (three-dimensional curved dome), which expands the adaptability of the traditional mutual support configuration, provides new ideas for the theoretical and practical development of the mutual support system, and improves the application scope of the contemporary mutual support system. At the same time, the present application adopts a modular design, splitting the woven wood dome into multiple first configuration arch frames and second configuration arch frames, each of which is a relatively independent unit, making the structure more flexible and expandable, for example, the number of arch frames can be increased or decreased as needed to adapt to different building needs and free-form surface shapes. In addition, the design of a cross bar and a second rod is adopted at the cross connection of the first configuration arch frame and the second configuration arch frame, that is, a horizontal and vertical locking relationship is formed between the woven wood dome components, and the mutual support and stability between the arch frames are achieved through the horizontal extension of the cross bar and the connection of the second rod. This cross connection design can effectively enhance the overall structural strength and stability of the woven wood dome. In this way, the woven wood dome of the present application realizes force circulation between units by constructing structural units of the same level and small scale (first configuration arch frame and second configuration arch frame), and realizes the overall span performance and surface adaptability of the frame with small-scale components.

[0009] As an achievable implementation, the angle between the axes of two adjacent first rods is less than 180 degrees, and a cross bar is provided on both sides of the connection nodes of two adjacent first rods along the first direction, respectively, and the cross bar is used to prevent the rotation of the two adjacent first rods relative to their own connection nodes in a third direction; wherein the third direction is the height direction of the woven wood dome.

[0010] In this embodiment, through the design of an angle less than 180 degrees and the setting of a cross bar, the cross bar can complete the reinforcement of two adjacent cross-connected first rods, that is, using the cross bar as a support and fixing point, the two first rods are individually pressed and locked, which effectively limits the deformation and swaying of the woven wood dome (first rod) in the height direction, and enhances its structural stability and reliability.

[0011] As a feasible implementation, the connection between two adjacent first rods includes any one of mortise and tenon joints, screw joints, hinge joints or riveted joints.

[0012] In this embodiment, by providing a variety of connection methods, the connection between two adjacent first rods is made more flexible. The designer can select the most suitable connection method according to specific needs to achieve the stability, reliability and applicability of the structure.

[0013] As a feasible implementation, the portion of the cross bar in contact with the first rod is provided with a first mortise for accommodating the first rod to be embedded, and the first rod is provided with a second mortise, and the first mortise and the second mortise are engaged with each other.

[0014] In this embodiment, the mortise design makes the connection between the crossbar and the first rod simpler and more convenient. During the construction process, the connection can be completed by simply aligning and embedding the mortise of the crossbar with the mortise of the first rod, without the need for additional tools or equipment. This simplified connection method helps to reduce construction time and labor costs, and improves construction efficiency. Through the design of the mortise, a tighter connection is formed between the crossbar and the first rod, effectively enhancing the stability and bearing capacity of the structure when subjected to stress. This connection method can reduce looseness and swinging in the structure, improve the structure's resistance to external loads and vibrations, and make the woven wood dome more stable and reliable during use, thereby bringing many advantages to the application and promotion of the woven wood dome.

[0015] As a feasible implementation, the angle between the axis of the second rod and the axis of the cross bar is less than 180 degrees, and the connection between the second rod and the cross bar includes any one of mortise and tenon, screw, hinge or riveted.

[0016] In this embodiment, the angle between the axis of the second rod and the axis of the cross bar is less than 180 degrees, so that the second rod and the cross bar present a certain inclination or angle relationship. In other words, the connection between the second rod and the cross bar is not horizontal. This can better adapt to different structural requirements and spatial layouts, increase the diversity and flexibility of the structure, and adapt to different free-form surface shapes.

[0017] As a feasible implementation, a mortise hole is provided at the cross connection between the second rod and the cross bar, a tenon pin is connected in the mortise hole, and the tenon pin is passed through the mortise hole to fix the second rod and the cross bar.

[0018] In this embodiment, the combination of the mortise and the tenon forms a very stable connection mode. The tenon is inserted into the mortise, so that the connection between the second rod and the crossbar is tighter and the structure is more stable.

[0019] As a feasible implementation, the mortise hole and the tenon pin are arranged in a square shape.

[0020] In this embodiment, the square mortise and tenon design is to increase the stability and tightness of the connection. The square design can better control the gap between the connecting parts, making the connection tighter and preventing looseness and shaking. In this way, the square mortise and tenon design has the advantages of high stability, strong bearing capacity, good precision and easy manufacturing in the structural connection, which improves the stability of the connection between the second rod and the crossbar, and at the same time improves the bearing capacity of the overall structure of the wooden dome, and can provide a reliable and lasting connection effect.

[0021] As an achievable implementation, the first rod, the cross rod and the second rod are in the shape of a round rod or a square rod.

[0022] In this embodiment, the round rod design can provide uniform stress distribution, making the connection more stable. The square rod design provides a larger contact area, increasing the stability of the connection. At the same time, both the round rod and the square rod are common material shapes, have high applicability, and can meet the connection requirements under different scenarios and requirements.

[0023] As a feasible implementation, the overall structural material of the woven wood dome is at least one of wood or metal.

[0024] In this embodiment, the overall structural material of the woven wood dome is designed to be at least one of wood or metal, which can fully utilize their respective characteristics, improve the stability, durability and aesthetics of the structure, and meet the use requirements of different occasions.

[0025] As a feasible implementation manner, the woven wood dome structure has a bidirectionally curved surface shape with positive Gaussian curvature.

[0026] In this embodiment, a positive Gaussian curvature surface shape is used in the woven wood dome structure, which can achieve uniform stress on the structure and a smoother appearance, which is beneficial to improving the stability and aesthetics of the structure and is suitable for the design and construction of various large-span building projects.

In this specification, the schematic representations of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in any one or more embodiments or examples in a suitable manner. In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0044] In order to more completely understand the present application, the following examples are given. These examples are used to specifically illustrate the embodiments of the present application, and should not be understood in any way as limiting the scope of the present application.

[0045] Reference Figure 2 and Figure 3 , a woven wood dome that can adapt to a free-form surface disclosed in an embodiment of the present application, comprises M first-configuration arch frames 1 extending and arranged along a first direction (X axis) and N second-configuration arch frames 2 extending and arranged along a second direction (Y axis). Wherein, M and N are positive integers greater than or equal to 2, M first-configuration arch frames 1 are arranged in parallel along the second direction, N second-configuration arch frames 2 are arranged in parallel along the first direction, and M first-configuration arch frames 1 and N second-configuration arch frames 2 are arranged in an interlaced manner to form a woven wood dome structure with a bidirectionally curved positive Gaussian curvature surface shape.

[0046] It can be understood that a positive Gaussian curvature surface is a surface with positive curvature, which exhibits the characteristics of bidirectional curvature. The shape of the bidirectionally curved positive Gaussian curvature surface is specifically manifested as a spherical or ellipsoidal surface. This surface has positive Gaussian curvature in all directions, showing the characteristics of convex outward, similar to a sphere or ellipsoid. The use of a positive Gaussian curvature surface shape in a woven wood dome structure can achieve uniform force and a relatively smooth appearance of the structure, which is conducive to improving the stability and aesthetics of the structure. Specifically, the positive Gaussian curvature surface has a uniform curvature distribution, which can make the structure present a uniform stress distribution when it is stressed. This can reduce the possibility of local stress concentration and improve the bearing capacity and wind resistance of the structure. The woven wood dome structure adopts a bidirectionally curved positive Gaussian curvature surface shape to achieve maximum space coverage. This structural form can cover a larger space range without increasing the support column, and is suitable for large-span space construction projects such as stadiums and exhibition halls. The woven wood dome structure with a positive Gaussian curvature surface shape usually has a simple structural form, reducing the number of structural nodes and connectors. This not only reduces the construction cost of the building, but also improves the overall stability and safety of the structure. The woven wood dome structure adopts a positive Gaussian curvature surface shape design, which can minimize the use of structural materials and reduce the energy consumption of the building. This is conducive to saving resources, reducing energy consumption, and conforming to the architectural concept of sustainable development.

[0047] It should be noted that the first direction is the width direction of the woven wood dome, the second direction is the length direction of the woven wood dome, and the plane formed by the first direction and the second direction is a horizontal plane. It is worth mentioning that the angle between the first direction and the second direction is less than 180 degrees. In other words, the length direction and the width direction of the woven wood dome can be set vertically or tilted to adapt to different building configurations. Exemplarily, for the convenience of description below, the angle between the first direction (represented by the X-axis in the accompanying drawings) and the second direction (represented by the Y-axis in the accompanying drawings) is 90 degrees.

[0048] See also Figure 4 and Figure 5 , the first configuration arch frame 1 includes at least two cross-arranged first rods 11, and the angle between the axes of two adjacent first rods 11 is less than 180 degrees. The designer can determine the number of first rods 11 connected to the first configuration arch frame 1 according to the required width span of the designed woven wood dome, and determine the cross-connection angle between two adjacent first rods 11 according to the surface curvature of the surface wood dome. It can be understood that since the curvature of the surface of the woven wood dome changes continuously, the cross-connection angle between the multiple first rods 11 extending along the first direction is also in a continuous change, and the cross-connection angles between the multiple first rods 11 on the first configuration arch frames 1 arranged side by side along the second direction are also different. Please refer to here Figure 3 The front view of the middle-woven wooden dome, Figure 3We can see that the crossing angle α between the first rods 11 on the first configuration arch frame 1 in the first row is small, and the crossing angle α gradually increases from the first row to the middle of the woven wood dome along the second direction, and then from the middle of the woven wood dome along the second direction to the last row, the size of the crossing angle α returns to the crossing angle of the first row from large to small.

[0049] In one embodiment, the connection between two adjacent first rods 11 includes any one of mortise, screw, hinge or riveting. For example, by respectively providing grooves and tenons (not shown) at the cross-contacting parts of two adjacent first rods 11, the two first rods 11 can bite each other to form a stable connection, which is suitable for scenes with high requirements for connection strength and stability; or, by using bolts or screws (not shown) at the cross-contacting parts of two adjacent first rods 11 to tightly connect the two first rods 11 together, it is suitable for scenes with small connection surfaces or frequent disassembly; or, by passing a rotating shaft (not shown) through the cross-contacting parts of two adjacent first rods 11, the two adjacent first rods 11 are allowed to rotate or swing within a certain range, which is suitable for scenes requiring flexibility and adjustability; or, by using rivets (not shown) to connect the two first rods 11 together, the riveted connection is firm and the structure is stable, which is suitable for scenes that need to withstand large loads or have high connection strength requirements. The designer can choose the most suitable connection method according to the specific situation and needs to achieve the best structural performance and stability. The present application does not impose strict restrictions here, as long as the two adjacent first rods 11 can stably maintain the cross-set X-supporting configuration.

[0050] It should be noted that, in order to further improve the stability of two adjacent first components in the third direction, in one example, a cross bar 21 is respectively provided on both sides of the connection node of two adjacent first rods 11 along the first direction, and the cross bar 21 is used to prevent the rotation of the two adjacent first rods 11 relative to their own connection node in the third direction; wherein the third direction (indicated by the Z axis in the attached figure) is the height direction of the woven wood dome. In this way, the cross bar 21 can play the role of supporting and locking the two first rods 11, so as to effectively limit the deformation and swing of the arch bridge in the height direction, and enhance the stability and reliability of its structure.

[0051] Optionally, the cross bar 21 and the first rod 11 may be connected by at least one of screw connection, bonding or tenon connection. Exemplarily, the cross bar 21 and the first rod 11 are connected by tenon connection. Figure 5 and Figure 6The portion of the cross bar 21 that contacts the first rod 11 is provided with a first mortise 3 for accommodating the first rod 11 to be embedded, and the first rod 11 is provided with a second mortise 4, and the first mortise 3 and the second mortise 4 are engaged with each other. The first mortise 3 and the second mortise 4 are engaged with each other to form a tight connection. This engaging connection can not only ensure a firm connection between the cross bar 21 and the first rod 11, but also effectively prevent them from falling off or shifting during use, thereby improving the safety and stability of the structure.

[0052] The second configuration arch 2 in the embodiment of the present application is introduced below in combination with the above introduction to the first configuration arch 1 and the structure of the cross bar 21 .

[0053] See also Figure 4 and Figure 5 The second configuration arch 2 includes at least two crossbars 21 extending horizontally along the second direction, and each crossbar 21 is cross-connected with two second rods 22. It should be noted that the angle between the axis of the second rod 22 and the axis of the crossbar 21 is less than 180 degrees. In other words, the crossbar 21 and the second rod 22 can be cross-connected in an X shape, or in a V shape or an inverted V shape (or end-to-end connection, see here for details). Figure 5 ), as long as the cross bar 21 and the second rod 22 are stably connected and the curvature of the woven wood dome surface is maintained. As described above for the first configuration arch frame 1, the cross bar 21 in the second configuration arch frame 2 is arranged on the first rod 11, and is used to support and lock the two cross-arranged first rods 11.

[0054] In one embodiment, adjacent crossbars 21 are connected to each other through second rods 22. The designer can determine the number of second rods 22 connected between two adjacent crossbars 21 according to the spacing between two adjacent crossbars 21 (depending on the length span of the woven wood dome) and the length of the second rods 22 used. It can be understood that in order to adapt to the curvature of the surface of the woven wood dome, the two connected second rods 22 are also arranged in a cross-connected structure (see Figure 5 ). The following describes the connection and fixing method between the cross bar 21 and the second rod 22 by assuming that two adjacent cross bars 21 are connected via a second rod 22.

[0055] See also Figure 5 and Figure 6Optionally, the connection method between the second rod 22 and the cross bar 21 includes any one of mortise, screw, hinge or riveting. Different connection methods have their own advantages and can meet the connection requirements in different scenarios. Exemplarily, the connection method between the second rod 22 and the cross bar 21 is mortise. Specifically, a mortise hole 5 is provided at the cross connection between the second rod 22 and the cross bar 21. The mortise hole 5 penetrates the second rod 22 and the cross bar 21 along the first direction, and a tenon pin 6 is connected in the mortise hole 5. The tenon pin 6 is inserted in the mortise hole 5 to fix the second rod 22 and the cross bar 21. The fixing method of the tenon pin 6 inserted in the mortise hole 5 makes the force borne by the structure more uniform, reduces the concentration of local stress, and thus improves the overall stability and bearing capacity of the structure. In order to increase the stability and tightness of the connection, the mortise hole 5 and the tenon pin 6 are set in a square shape. The square mortise hole 5 combined with the tenon pin 6 can provide a larger contact area, increase friction, and maintain the stability of the connection. Moreover, the square design can withstand greater tensile and compressive forces, thereby improving the overall bearing capacity of the structure. The implementation of the screw connection, hinge connection or riveting connection between the second rod 22 and the cross bar 21 can refer to the specific description of the connection between two adjacent first rods 11 above, and will not be repeated here.

[0056] In one possible implementation, the first rod 11, the cross bar 21 and the second rod 22 are shaped as a round rod or a square rod. The overall structural material of the woven wood dome is at least one of wood or metal. It is understandable that designing the first rod 11, the cross bar 21 and the second rod 22 as round rods or square rods has the advantages of wide applicability, high stability, easy processing and good aesthetics. This design can provide a reliable connection effect and is suitable for structural connection requirements under various scenarios and needs. Wood and metal are both common structural materials, each with specific physical and mechanical properties. The selection of wood or metal as the material for the overall structure of the woven wood dome is mainly determined according to specific use requirements and environmental conditions to meet the structural requirements of load-bearing, stability, durability, etc. For example, wood has good thermal insulation and environmental protection properties, and can play a good role in some occasions where temperature needs to be maintained. At the same time, wood can also be processed by cutting, carving, etc. to form various complex structures, and has a wide range of applications; while metal has good strength and corrosion resistance, and is more suitable for some occasions that need to bear large loads or harsh environments. At the same time, metal has good plasticity and can be processed, cast, etc. to create various shapes and structures, with high flexibility. Both wood and metal can provide good structural stability. The fiber structure of wood makes it flexible and can buffer external shocks or vibrations; while the strength and rigidity of metal can ensure the stability of the structure and is not easy to deform or break.

[0057] After construction verification, the ratio of the component size to the span of the woven wood dome exceeded the limit that can be achieved in traditional woven wood arches with a ratio range of 8.17-8.56. Under the preset condition of 1.5 times the constant load, the bending moment distribution of the new configuration is within the allowable range of ±15KNm. During the construction process, although the woven wood dome was built only with pine wood, the structure was stable, and the structural deformation after completion was only 2.7%, demonstrating its superior structural performance and span capacity.

[0058] The new configuration of the woven wood dome provided in the embodiment of the present application starts from the spatial axis, and applies the one-way curved surface in the mutual support configuration of the traditional woven wood arch to the two-way curved surface. At the same time, the second configuration arch frame 2 (the arch frame where the cross bar 21 is located) is still formed horizontally at the intersection of the first configuration arch frame 1 to form a reinforcement for the first configuration arch frame 1. In general, the node-type configuration of the woven wood dome is still based on the first configuration arch frame 1 as the traditional woven wood arch prototype, and the second configuration arch frame 2 needs to have the task of reinforcing the mutual support of the first configuration arch frame 1 and forming a one-way curvature curved surface. The first configuration arch frame 1 and the second configuration arch frame 2 form a horizontal and vertical compression lock and mutual support relationship with each other, forming a morphological texture like a woven fabric, so that the hierarchical relationship and force role of the woven wood dome are more similar to the prototype, and the new configuration can freely adapt to the two-way curved surface while retaining the curvature change of the surface. In this way, the woven wood dome of the present application realizes force circulation between units by constructing structural units of the same level and small scale (first configuration arch frame 1 and second configuration arch frame 2), and realizes the span performance and curved surface adaptability of the whole frame with small-scale components (first rod 11, cross bar 21 and second rod 22), which can be used as a relatively economical and low-carbon frame structure option. The woven wood dome can provide more possibilities for contemporary inter-supporting frame building types and corresponding design theories, and provide new directions for the future application and development of node-type inter-supporting frames.

[0059] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application. Those skilled in the art should understand that, although the present application is described in detail with reference to the aforementioned embodiments, the technical solutions described in the aforementioned embodiments can still be modified, or some of the technical features can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions in the embodiments of the present application.
