Description

Technical Field

[0001] This disclosure relates to the field of architectural decoration technology, and more specifically, to a multifunctional pivot splicing component. Background Technology

[0002] In the fields of architectural decoration, exhibition and spatial design, curved walls are widely used in commercial complexes, art galleries and high-end residences due to their smooth curved visual effect. However, the existing construction technology and prefabricated component structure of curved walls still have many practical pain points, which restrict construction efficiency and shape adaptability.

[0003] Currently, the conventional solutions for creating curved walls in the industry are mainly divided into two categories: on-site cast-in-place molding and prefabricated groove splicing on the ground. On-site cast-in-place molding involves casting on-site with formwork. This method requires custom-made curved templates according to the curvature of the curve. The template opening cycle is long and the processing cost is high. The casting and curing process is also time-consuming, making it impossible to achieve rapid assembly and construction. It is extremely unsuitable for small-batch, irregularly shaped curved wall customization scenarios. Prefabricated groove splicing on the ground involves pre-casting and slotting prefabricated groove base components with corresponding curvature on the ground, and then embedding the wall panels into the groove base to complete the curvature positioning. Although this solution can guarantee the accuracy of the curve to a certain extent, the prefabrication process of the groove is cumbersome. It not only significantly increases the amount of pre-construction work, but also has a long casting and curing time (e.g., at least 2-3 days for casting and forming). It can only be used after drying and curing. In addition, the groove mold must correspond one-to-one with the curvature of the curve. If the curvature of the wall needs to be adjusted later, it will increase the difficulty of adjustment.

[0004] Traditional curved wall structures rely on base grooves for positioning and fixing, resulting in poor flexibility in disassembly and modification. When the building space layout is adjusted or the wall shape is modified, it cannot be quickly disassembled and reassembled, leading to low component reuse rate and a double waste of building materials and construction manpower.

[0005] While some modular splicing solutions attempt to simplify the process, they are structurally complex and require additional special connectors, such as clips. Furthermore, the materials used are mostly solid wood and metal, which, due to their weight, are prone to collapse during installation and splicing, posing safety hazards. In addition, the curvature is small, making it difficult to achieve a large curvature shape that is "close to a circle".

[0006] Prior art 1 (application number: 201520916029.4, application date: 2015.11.17) discloses a novel building formwork and snap-fit ​​connector, including: a formwork, upper and lower formwork connecting pins, snap-fit ​​connectors, a left side plate, a left hook-shaped body, a circular recessed groove, a pin hole, a reinforcing rib, a right hook-shaped body, a right side plate, a circular convex latch, an arched jacking bracket, a hook-shaped groove, a strip-shaped limiting body, and a reinforcing hole. The formwork has a door-shaped structure design, and a circular recessed groove is provided at the left end of the formwork. The lower part of the circular recessed groove is the left side plate, and the bottom of the left side plate... The template features a left hook-shaped body and a circular protruding latch at the right end. Below the circular protruding latch is a right side plate, and at the bottom of the right side plate is a right hook-shaped body. A pin hole is located in the middle of the template, and a reinforcing rib is located below the pin hole. The snap-fit ​​connector has a U-shaped structure. The upper half of the snap-fit ​​connector has bow-shaped push supports on both sides, and a hook-shaped groove in the center. A strip-shaped limiting body is located in the middle of the bottom of the hook-shaped groove. The lower half of the snap-fit ​​connector also has three reinforcing holes in the middle and on both sides. This solution requires the fabrication of various shapes of combined templates, such as arcs, bends, and inclinations, to meet different construction site requirements. These are then assembled into a single unit, making the assembly process complex. Furthermore, different shaped templates need to be prefabricated as needed, resulting in low reusability.

[0007] Prior art 2 (application number: 202221884360.9, application date: 2022.07.21) discloses a prefabricated curved wall panel, including a keel (1), a wall panel (2), a wall panel connector (3), a wall panel fastener (4), and a keel connector (5); the keels (1) are arranged at intervals along the wall surface, and the space between the keels (1) forms the space for installing the wall panel (2); two adjacent wall panels (2) are joined to each other by the wall panel connector (3), and the wall panel (2) is joined to the keel (1) between the two wall panels (2) by the wall panel connector (3); the wall panel connector (3) is joined to the wall panel (2) by the wall panel fastener (4). This solution requires a movable allowance 43 between the wall panel fastener (4) and the joint groove (31), thereby making the angle between the wall panel (2) and the wall panel connector (3) adjustable to meet the installation requirements of the curved wall panel.

[0008] Therefore, the existing technologies for constructing arc-shaped walls have the following problems: 1. the need to prefabricate ground groove components, resulting in a long project cycle; 2. difficulty in adapting to various arc shapes with different curvatures, especially large curvatures. These problems urgently need to be solved in this field. Summary of the Invention

[0039] Reference Figures 1-4 A multifunctional pivot-type splicing component 001 includes a first connecting end 100 and a second connecting end 200, which are connected by an intermediate portion.

[0040] The first connecting end 100 is a cylindrical structure extending in the vertical direction (Y direction), including a first groove 101. The first groove 101 is an arc-shaped groove that is recessed from the first connecting end 100 toward the second connecting end 200 and extends in the vertical direction (Y direction). The opening of the first groove 101 is smaller than the inner diameter of the first groove 101.

[0041] The second connecting end 200 includes a second groove 201, which is an arc-shaped groove that is recessed from the second connecting end 200 toward the first connecting end 100 and extends in the vertical direction (Y direction). The opening of the second groove 201 is smaller than the inner diameter of the second groove 201. The second connecting end 200 also includes a first protrusion 202, which is a cylindrical protrusion that protrudes from the first connecting end 100 toward the second connecting end 200 and extends in the vertical direction (Y direction). The first protrusion 202 is located inside the second groove 201 and is connected to the bottom of the groove of the second groove 201.

[0042] On the horizontal plane in the first direction (X direction), the centers of the arc-shaped cross-sections of the first groove 101, the second groove 201, and the first protrusion 202 are located on the same axis along the first direction (X direction). The first direction is the direction from the second connecting end 200 to the first connecting end 100. The first groove 101, the second groove 201, and the first protrusion 202 are symmetrical about the same axis along the first direction. That is, the centers of the arc-shaped cross-sections of the first groove 101, the second groove 201, and the first protrusion 202 are coaxial, and the first groove 101, the second groove 201, and the first protrusion 202 all have this axis as their axis of symmetry, and are symmetrical structures.

[0043] The first protrusion 202 of the multi-functional pivot splice 001 is inserted into the first groove 101 of the adjacent multi-functional pivot splice 001. The first protrusion 202 is enclosed in the first groove 101 of the adjacent multi-functional pivot splice 001, and the first connecting end 100 is enclosed in the second groove 201 of the adjacent multi-functional pivot splice 001. There is a clearance fit between the first protrusion 202 and the first groove 101, and a clearance fit between the first connecting end 100 and the second groove 201.

[0044] Specifically, the multifunctional pivot splicing component 001 disclosed herein has a symmetrical structure with the center of the arc-shaped cross-section of the first groove 101, the center of the arc-shaped cross-section of the second groove 201, the center of the arc-shaped cross-section of the first protrusion 202, the axis in the X direction, and the cross-section extending along the Y direction as symmetrical cross-sections.

[0045] In this disclosure, the first protrusion 202 is located within the second groove, meaning the outer diameter of the first protrusion is smaller than the inner diameter of the second groove, and the first protrusion 202 is enclosed within the first groove 101 of the adjacent multifunctional pivot splice 001, meaning the outer diameter of the first protrusion is smaller than the inner diameter of the first groove 101, forming a clearance fit; the first connecting end 100 is enclosed within the second groove 201 of the adjacent multifunctional pivot splice 001, and the first connecting end has an arc-shaped structure, with its outer diameter needing to be smaller than the inner diameter of the second groove 201, forming a clearance fit; the first protrusion 202, the first groove 101, and the second groove 201 are all clearance fits. In this disclosure, the dimensions of the first protrusion 202, the first groove 101, and the second groove 201 are not specifically limited, only that a gap is formed between the three to ensure smooth rotation and to allow them to be locked during rotation, i.e., not completely unscrewed, thus preventing detachment. The specific dimensions can be adaptively adjusted according to the overall width, thickness, and rotation angle.

[0046] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 In some optional embodiments provided in this disclosure, the intermediate portion includes a first intermediate sub-portion 300 and a second intermediate sub-portion 400 connected in sequence, one end of the first intermediate sub-portion 300 being connected to the first connecting end 100; and one end of the second intermediate sub-portion 400 being connected to the second connecting end 200 via a connecting portion.

[0047] Along the first direction (X direction), the first intermediate sub-section 300 is a converging cone, wherein the converging end of the first intermediate sub-section 300 is connected to the first connecting end 100, and the diverging end of the first intermediate sub-section 300 is connected to the second intermediate sub-section 400.

[0048] Specifically, in this disclosure, one end of the first intermediate sub-part is connected to the first connecting end, and the other end is connected to the second intermediate sub-part. One end of the second intermediate sub-part is connected to the first intermediate sub-part, and the other end is connected to the second connecting end. By setting the intermediate part as the first intermediate sub-part and the second intermediate sub-part, different functional structures can be set according to different functional requirements.

[0049] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 In some optional embodiments provided in this disclosure, the cross-section of the first intermediate sub-part 300 is trapezoidal in the horizontal plane of the first direction (X direction). The upper base of the trapezoid extends vertically to form a converging end, and the lower base extends vertically to form a diverging end, wherein the length of the lower base is greater than the length of the upper base. Optionally, the cross-section of the first intermediate sub-part 300 is an isosceles trapezoid in the horizontal plane of the first direction (X direction).

[0050] Specifically, the first intermediate sub-part 300 is configured as a converging cone, wherein the converging end is connected to the first connecting end 100 and the diffuser end is connected to the second intermediate sub-part 400. The converging end can provide enough space for rotation when the multi-functional pivot splice is connected, avoiding interference during rotation due to insufficient space, which would result in an excessively small rotation angle.

[0051] In this disclosure, the first intermediate sub-section is designed as a cone structure, which can increase the rotation angle and realize a multi-angle arc-shaped wall base; and can enhance the structural strength and prevent breakage.

[0052] It should be noted that the dimensions of the first intermediate sub-part are not further limited in this disclosure. The first intermediate sub-part needs to provide sufficient space for the first protrusion and the first groove to rotate during the installation process, and ensure that it has sufficient strength and is not easily broken.

[0053] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 In some optional embodiments provided in this disclosure, the second intermediate sub-part 400 includes two end faces 401 extending in the vertical direction (Y direction) and disposed opposite to each other. A third groove 402 extending in the vertical direction (Y direction) is provided on the end face 401. The third groove 402 is a rectangular groove recessed from the end face 401 toward the intermediate area sandwiched between the two end faces 401. At the bottom of the third groove 402, a fourth groove 403 extending in the vertical direction (Y direction) is provided in the center. The fourth groove 403 is an arc-shaped groove whose recess direction is consistent with the recess direction of the third groove 402.

[0054] Specifically, this disclosure provides a third groove 402 extending in the vertical direction (Y direction) on the second connecting part 400. The third groove 402 is recessed inward from the end face in the Z direction. The third groove 402 serves as a nail head. At the bottom of the third groove 402, a fourth groove 403 extending in the vertical direction (Y direction) is provided in the center. The fourth groove 403 is an arc-shaped groove with the same recess direction as the third groove 402. That is, the fourth groove 403 is located in the groove of the third groove and is also recessed inward from the end face in the Z direction. The fourth groove 403 serves as a positioning function for nailing.

[0055] In this disclosure, each multi-functional pivot splice is provided with a nail groove (third groove 402), which can be nailed to the back plastic keel according to use.

[0056] The multifunctional hinge-type splicing component 001 disclosed herein can be obtained by 3D printing. The multifunctional hinge-type splicing component 001 disclosed herein can also be made of other processes or materials, which will not be elaborated here.

[0057] In some optional embodiments provided in this disclosure, the opening size of the first groove 101 is smaller than the outer diameter of the first protrusion 202. The dimensions of the first groove 101, the first protrusion 202, and the second groove 201 are matched to form a stable structure that can both rotate and be locked in place without falling off.

[0058] In some optional embodiments provided in this disclosure, the first protrusion 202 and the second groove 201 are connected by an arc to avoid stress concentration and prevent breakage.

[0059] This disclosure does not specify the dimensions of the multi-functional hinge-type splicing component. The individual specifications of the multi-functional hinge-type splicing component can be adjusted according to the curvature of the components to be spliced, achieving splicing of different curvatures. For example, for arc-shaped components of different radii, when the radius of the arc-shaped component is larger, the overall width and thickness of the multi-functional hinge-type splicing component can be appropriately larger; for arc-shaped components with smaller radii, the overall width and thickness of the multi-functional hinge-type splicing component can be smaller as needed. For arc-shaped components of the same radius, the width of the multi-functional hinge-type splicing component can be smaller, in which case the number of overall splicing pieces increases accordingly; alternatively, a wider width can also achieve splicing of arc-shaped components, in which case the number of overall splicing pieces decreases accordingly.

[0060] In this disclosure, by adjusting the rotation angle between two adjacent multi-functional pivot-type splicing components and the overall width, the assembly of multi-sized and multi-angle arc-shaped or planar components can be achieved. The multi-functional pivot-type splicing component of this disclosure can assemble planar components as well as near-circular arc-shaped components. Correspondingly, the vertical height of the multi-functional pivot-type splicing component can also be adjusted as needed. For example, if it needs to be fixed to the roof and ground respectively, the vertical height of the multi-functional pivot-type splicing component should match the height of the installation space; if it does not need to be fixed to the roof or ground respectively, the vertical height of the multi-functional pivot-type splicing component is less than the height of the installation space.

[0061] In some optional embodiments provided in this disclosure, reference is made to Figure 2 The connecting portion 500 includes a planar connecting portion 501, a first arc-shaped surface connecting portion 502, and a second arc-shaped surface connecting portion 503 connected in sequence; the planar connecting portion 501 is connected to the opening end of the second groove 201; the arc of the first arc-shaped surface connecting portion 502 is smaller than that of the second arc-shaped surface connecting portion 503, and the radius of the first arc-shaped surface connecting portion 502 is smaller than that of the second arc-shaped surface connecting portion 503; the other end of the second arc-shaped surface connecting portion 503 is connected to the end face 401 of the second intermediate sub-part 400.

[0062] In this disclosure, the connecting part 500 is configured as a structure in which a planar connecting part 501, a first arc-shaped connecting part 502, and a second arc-shaped connecting part 503 are connected in sequence. The two multi-functional pivot splicing parts can be more easily inserted and the rotation angle can be increased. The second arc-shaped connecting part 503 is arc-shaped, which is more conducive to smooth shaping under different conditions.

[0063] To reduce structural weight and manufacturing costs, the interiors of the first intermediate sub-part 300 and the second intermediate sub-part in the multifunctional pivot-type splicing component of this disclosure are designed with a hollow structure; the first protrusion 202 is designed with a hollow structure along the vertical direction. Other forms of the internal structure may also exist, which will not be elaborated upon here.

[0064] Example 1

[0065] Reference Figure 3The aforementioned multifunctional pivot splicing component 001 is used, with multiple components connected sequentially. Specifically, the first multifunctional pivot splicing component 001 and the second multifunctional pivot splicing component 001 are connected along the first direction (X direction). The connection method is that the first groove 101 of the first multifunctional pivot splicing component 001 is inserted into the gap between the second groove 201 and the first protrusion 202 in the second multifunctional pivot splicing component 001. That is, the first groove 101 of the first multifunctional pivot splicing component 001 wraps the first protrusion 202 in the adjacent second multifunctional pivot splicing component 001, and at the same time, the first groove 101 of the first multifunctional pivot splicing component 001 is wrapped by the second groove 201 in the adjacent second multifunctional pivot splicing component 001. The specific assembly method is as follows: Place the first multi-functional pivot-type splicing component 001 stably, then align the first protrusion 202 of the second multi-functional pivot-type splicing component 001 with the first groove 101 of the first multi-functional pivot-type splicing component 001, while ensuring that the first groove 101 of the first multi-functional pivot-type splicing component 001 is aligned with the second groove 201 of the second multi-functional pivot-type splicing component 001. Pull axially along the Y direction until the upper and lower end faces (i.e., the two opposite planes in the Y direction) of the two adjacent multi-functional pivot-type splicing components 001 are aligned. Install the other multi-functional pivot-type splicing components 001 in the same way until the required length is reached, forming an upright planar wall assembly.

[0066] After being connected to form a planar wall component, the component is fixed to the wall joists by nailing or gluing. Depending on the application scenario, the surface of the wall component undergoes different treatments. For example, if the wall component is intended as the final decorative finish, it can be completely wrapped during the manufacturing stage and then installed directly on-site as a decorative surface. If it is paired with an independent decorative panel as an exposed decorative layer, structural adhesive can be used to bond and fix the additional panel to the wall component, in which case the wall component serves as an internal base layer. It should be noted that when the application scenario is not floor-to-ceiling (i.e., the vertical space of the component is greater than or equal to the height of the multi-functional pivot splice, where the vertical space refers to the vertical height of the scenario where the multi-functional pivot splice is installed), any splice can be disassembled individually and reused.

[0067] During disassembly, pull the multi-functional swivel-type splicing component 001 axially along the Y direction until it is completely separated, thus disassembling the multi-functional swivel-type splicing component 001. If the application scenario is a top-to-bottom structure, it is not possible to disassemble a single splicing component in the middle section into a separate keel component.

[0068] Example 2

[0069] Reference Figure 4The aforementioned multifunctional pivot splicing component 001 is used, with multiple components connected sequentially. Specifically, the first multifunctional pivot splicing component 001 and the second multifunctional pivot splicing component 001 are connected along the first direction (X direction). The connection method is that the first groove 101 of the first multifunctional pivot splicing component 001 is inserted into the gap between the second groove 201 and the first protrusion 202 in the second multifunctional pivot splicing component 001. That is, the first groove 101 of the first multifunctional pivot splicing component 001 wraps the first protrusion 202 in the adjacent second multifunctional pivot splicing component 001, and at the same time, the first groove 101 of the first multifunctional pivot splicing component 001 is wrapped by the second groove 201 in the adjacent second multifunctional pivot splicing component 001. The specific assembly method is as follows: Place the first multi-functional pivot splicing component 001 stably, then align the first protrusion 202 of the second multi-functional pivot splicing component 001 with the first groove 101 of the first multi-functional pivot splicing component 001, while ensuring that the first groove 101 of the first multi-functional pivot splicing component 001 is aligned with the second groove 201 of the second multi-functional pivot splicing component 001. Pull along the Y-direction axial direction until the upper and lower end faces (i.e., the two planes opposite each other in the Y-direction) of the two adjacent multi-functional pivot splicing components 001 are aligned. Then rotate the multi-functional pivot splicing component 001 so that the two adjacent multi-functional pivot splicing components 001 form a certain angle (adjust the angle according to the curvature of the final required arc wall). After multiple multi-functional pivot splicing components 001 are connected and rotated in sequence, the required arc wall component is formed. On the vertical end face of this arc-shaped wall component, flexible wall panels, such as wallpaper or bendable aluminum panels, can be attached to obtain an arc-shaped wall base; alternatively, the entire component can be completely wrapped during the processing stage and then directly installed on-site as a decorative surface.

[0070] By using the multi-functional pivot-type splicing components disclosed herein, the installation angle can be adjusted to create curved, flat, or polygonal wall framing structures, thus achieving different wall shapes as required by varying site conditions. Furthermore, the multi-functional pivot-type splicing components allow for direct on-site assembly, eliminating the need for pre-fabricated floor recesses and significantly reducing construction time, enabling rapid assembly.

[0071] As can be seen from the above embodiments, the multifunctional pivot splicing component provided in this disclosure achieves at least the following beneficial effects:

[0072] 1. The multi-functional pivot splicing component disclosed herein has a first groove at one end and a second groove at the other end. The second groove is provided with a first protrusion. The first groove engages with the first protrusion and the second groove respectively. By rotating the engagement angle, wall shapes with different curvatures can be achieved.
