Description

Technical Field

[0001] This utility model relates to the field of curtain wall technology, and in particular to an irregularly shaped hyperboloid curtain wall unit. Background Technology

[0002] Curved curtain walls, with their unique curved shapes and dynamic aesthetic effects, are widely used in modern architecture, enabling complex geometric forms and light and shadow interactions. However, their construction and structural design face significant challenges.

[0003] Traditional curved curtain wall installation involves on-site installation, with each unit installed individually according to the specific curved surface requirements, resulting in low installation efficiency. To improve the installation efficiency of curved curtain walls, a unitized curtain wall structure has been proposed. This structure divides the curved curtain wall into multiple units, which are precisely manufactured and assembled into complete modules in a controlled factory environment before being transported to the construction site for assembly. Unitized curtain walls can significantly improve installation efficiency and reduce on-site construction time.

[0004] However, for some complex curved curtain wall units, especially irregular hyperboloid curtain wall units, multiple stiffening plates are set inside the irregular hyperboloid curtain wall unit. All stiffening plates are connected by only a single connecting rod, which cannot form multi-directional constraints. This results in low installation stability of the stiffening plates, causing misalignment between the stiffening plates. Ultimately, the irregular hyperboloid structure cannot meet the designed appearance effect.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

[0006] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a non-standard hyperboloid curtain wall unit, which aims to solve the technical problems of unstable stiffener installation structure and difficulty in achieving the designed appearance effect of non-standard hyperboloid structure in the prior art.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A type of irregular hyperboloid curtain wall unit includes:

[0009] Curved sheet material with a sharp corner;

[0010] Several spaced stiffeners are provided, each stiffener is located on the inner side of the curved sheet, and the edge of each stiffener is connected to the inner side of the curved sheet through a first corner bracket.

[0011] A first link and a second link, wherein the first link passes through all stiffening plates and forms a one-to-one connection node with each stiffening plate through a second angle bracket, and the second link passes through all stiffening plates and forms a one-to-one connection node with each stiffening plate through a third angle bracket; at least two third links are provided between the first link and the second link.

[0012] Furthermore, each of the stiffeners has a notch at its top, and a first connecting rod is embedded in all the notches of the stiffeners. Each notch is connected to the first connecting rod via a second corner bracket. The top of the first connecting rod has at least two connecting parts.

[0013] Furthermore, each of the stiffening plates has a through hole in the middle, and the second connecting rod passes through the through holes of all the stiffening plates. Each through hole is connected to the second connecting rod through a third angle bracket.

[0014] Furthermore, the inner wall of the sharp corner is provided with a connector, which includes a first connecting surface, a second connecting surface and a third connecting surface connected in sequence. The first connecting surface and the third connecting surface are respectively connected to the two inner sides of the sharp corner, the third connecting surface faces the tip of the sharp corner, and is connected to the bottom of the corresponding stiffening plate through a fourth corner bracket.

[0015] Furthermore, the curved sheet is composed of a first sheet and a second sheet spliced ​​together, with the sharp corner located on the first sheet; the first sheet is connected to the second sheet via a connecting piece.

[0016] Furthermore, both ends of the curved sheet are provided with a first flange that bends inward, and at least one side edge of the curved sheet is provided with a second flange that bends inward.

[0017] Furthermore, the curved sheet has an extension on the side away from the second flange, and an L-shaped support strip is provided on the inner wall of the curved sheet. The L-shaped support strip is located near the extension and forms a one-to-one connection node with each stiffener through the fifth corner bracket. The L-shaped support strip is used to install linear lights.

[0018] Furthermore, it also includes a plurality of sixth angle brackets spaced apart along the length of the L-shaped support strip. One side of each sixth angle bracket is connected to the L-shaped support strip through a first buffer pad, and the other side is connected to the extension through a second buffer pad.

[0019] Furthermore, the end of the L-shaped support bar is provided with a wire hole.

[0020] Beneficial effects:

[0021] This utility model provides a non-standard hyperboloid curtain wall unit with the following advantages: (1) The first and second connecting rods penetrate all the stiffening plates and work together with the third connecting rod to form a linkage, realizing the horizontal and vertical linkage constraint of the multi-stiffening plates, avoiding the displacement and misalignment of the stiffening plates, ensuring the installation stability of the curved sheet and the overall anti-deformation ability, and meeting the high-precision appearance requirements of complex hyperboloids; (2) Connectors are set on the inner side of the sharp corners to form a triangular stable structure, which significantly improves the rigidity of the sharp corners and avoids the deformation of the sharp corners; (3) The use of segmented spliced ​​curved sheet reduces the processing difficulty of a single curved sheet, enabling the realization of highly complex hyperboloid shapes, while providing adjustment space for the installation of sharp corners.

[0030] This utility model provides an irregularly shaped hyperboloid curtain wall unit. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

Therefore, they should not be construed as limitations on this utility model. Furthermore, "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "multiple" means two or more.

[0032] Please see Figures 1 to 7 As shown, this utility model provides an irregularly shaped hyperboloid curtain wall unit, including: a curved sheet 1, a plurality of spaced stiffeners 3, a first connecting rod 4 and a second connecting rod 5, wherein the curved sheet 1 has a pointed corner 2; each stiffener 3 is disposed on the inner side of the curved sheet 1, and the edge of each stiffener 3 is connected to the inner side of the curved sheet 1 through a first angle bracket 31; the first connecting rod 4 passes through all stiffeners 3 and forms a one-to-one connection node with each stiffener 3 through a second angle bracket 41, and the second connecting rod 5 passes through all stiffeners 3 and forms a one-to-one connection node with each stiffener 3 through a third angle bracket 51; at least two third connecting rods 6 are provided between the first connecting rod 4 and the second connecting rod 5.

[0033] The first link 4 and the second link 5 are connected by the third link 6 to ensure a relatively stable structure. By setting the first link 4 and the second link 5 to pass through all the stiffening plates 3, and using the second angle bracket 41 and the third angle bracket 51 to form a one-to-one connection point with each stiffening plate 3, the multiple stiffening plates 3 form a two-way rigid constraint (lateral and longitudinal linkage) in three-dimensional space, which ensures the installation stability of each stiffening plate 3, prevents the stiffening plates 3 from shifting and misaligning with each other, and thus ensures that the installation of the curved sheet 1 will not deform, and can meet the designed appearance effect.

[0034] In a preferred embodiment, see [reference] Figure 3Each stiffening slab 3 has a notch 32 at its top, and a first connecting rod 4 is embedded in all the notches 32 of the stiffening slabs 3. Each notch 32 is connected to the first connecting rod 4 via a second angle bracket 41. The top of the first connecting rod 4 has at least two connecting parts 42. By fixing the first connecting rod 4 to the top of all the stiffening slabs 3 through the notches 32, it is possible to ensure that the connecting parts 42 on the first connecting rod 4 do not interfere with the position of the stiffening slabs 3, thereby improving the flexibility of installing irregular hyperboloid curtain wall units.

[0035] In the above description, the connecting part 42 is fixed to the first connecting rod 4 by welding. The connecting part 42 enables the installation of irregular hyperboloid curtain wall units. In practical applications, the wall or curtain wall system is connected to the connecting part 42 through connecting fittings. Under the action of the connecting part 42, the connecting fittings are kept away from the stiffening plate 3, which can effectively avoid positional interference between the stiffening plate 3 and the connecting fittings.

[0036] Furthermore, each notch 32 is connected to the first link 4 via two symmetrically arranged second corner brackets 41 to further improve the connection stability between the stiffener 3 and the first link 4.

[0037] Preferably, one end of the third link 6 is welded and fixed to the bottom of the first link 4, and the other end is connected to the second link 5 through the seventh corner bracket 61 to form a structurally stable link assembly structure, thereby ensuring the stability of the installation of each stiffener 3 and preventing misalignment.

[0038] In a preferred embodiment, see [reference] Figure 3 , 7 Each stiffening plate 3 has a through hole 33 in its center. The second connecting rod 5 passes through all the through holes 33 of the stiffening plates 3. Each through hole 33 is connected to the second connecting rod 5 through a third angle bracket 51. Specifically, the through holes 33 match the second connecting rod 5. The cooperation between the through holes 33 and the third angle bracket 51 makes the connection between the second connecting rod 5 and each stiffening plate 3 stable, avoiding local stress concentration caused by traditional welding fixation, and thus making the installation position of the stiffening plate 3 less prone to deformation.

[0039] The coordinated positioning design of through hole 33 and notch 32 enables rapid assembly of the first connecting rod 4, the second connecting rod 5 and each stiffening plate 3, reducing assembly and adjustment time.

[0040] In practical applications, the shape of each stiffener 3 and the position of each hole should be processed according to the appearance design requirements of the irregular hyperboloid curtain wall unit, such as the curvature change requirements of the curved sheet 1, and assembled onto the first connecting rod 4 and the second connecting rod 5 in sequence. Under the condition that each stiffener 3 is installed stably and will not be displaced, the appearance of the irregular hyperboloid curtain wall unit meets the design requirements.

[0041] In a preferred embodiment, see [reference] Figure 4 The inner wall of the pointed corner 2 is provided with a connector 7, which includes a first connecting surface 71, a second connecting surface 72, and a third connecting surface 73 connected in sequence. In this embodiment, the pointed corner 2 is an acute angle, which is provided to enhance the unique shape of the irregular hyperboloid curtain wall unit. However, since the pointed corner 2 has a small thickness and a long length, it is prone to deformation. To avoid this, the connector 7 is used to connect the pointed corner 2 to the stiffening plate 3.

[0042] Specifically, the first connecting surface 71 and the third connecting surface 73 are respectively connected to the two inner sides of the sharp corner 2, with the third connecting surface 73 facing the tip of the sharp corner 2, and connected to the bottom of the corresponding stiffening plate 3 through the fourth corner bracket 34. Through this arrangement, the sharp corner 2 and the connecting piece 7 form a stable triangular structure, improving the rigidity of the sharp corner 2 and preventing deformation of the sharp corner 2 due to misoperation, thus affecting its aesthetic appearance.

[0043] In a preferred embodiment, see [reference] Figure 3 , 5 The curved sheet 1 is composed of a first sheet 11 and a second sheet 12 spliced ​​together, with the sharp corner 2 located on the first sheet 11; the first sheet 11 is connected to the second sheet 12 via a connecting piece 13. The segmented design reduces the processing difficulty of a single curved sheet 1, allowing for the creation of highly complex hyperboloid shapes through bending and splicing of individual sheets.

[0044] Preferably, the connecting piece 13 extends along the length of the curved sheet 1. Several screws are riveted onto the first sheet 11. The screws are used to fix one side of the connecting piece 13, and the other side of the connecting piece 13 abuts against the second sheet 12 to achieve splicing of the first sheet 11 and the second sheet 12.

[0045] In addition, during actual installation, the first sheet 11 can be fixed to each stiffening plate 3 first, and then the second sheet 12 can be fixed to provide more operating space to fix the position of the first sheet 11 and the sharp corner 2.

[0046] In a preferred embodiment, see [reference] Figure 1 , 3 The curved sheet 1 has inwardly bent first flanges 14 at both ends and at least one side edge of the curved sheet 1 has inwardly bent second flanges 15. By setting the first flanges 14 and the second flanges 15, the stiffness of the edge position is improved, the bending stiffness is increased by about 30%, and the edge deformation during transportation and installation is effectively suppressed.

[0047] In this embodiment, the curved sheet 1 has a second flange 15 on one side and an extension 16 on the other side.

[0048] See Figure 2, 6 Specifically, the inner wall of the second sheet 12 is provided with an L-shaped support strip 17. The L-shaped support strip 17 is located near the extension 16 and is fixed to the second sheet 12 by welding. The L-shaped support strip 17 forms a one-to-one connection node with each stiffening plate 3 through the fifth angle bracket 35 to achieve stable installation of the L-shaped support strip 17. The L-shaped support strip 17 is used to install linear lights, realizing the integrated installation of lighting equipment and curtain wall structure. The linear lights are hidden between the L-shaped support strip 17 and the extension 16, reducing exposed pipelines and improving the aesthetics of the curtain wall.

[0049] Furthermore, it also includes a plurality of sixth angle brackets 171 spaced apart along the length of the L-shaped support strip 17. One side of each sixth angle bracket 171 is connected to the L-shaped support strip 17 via a first buffer pad 172, and the other side is connected to the extension 16 via a second buffer pad 173. Preferably, the first buffer pad 172 and the second buffer pad 173 are made of EPDM rubber gaskets, which can absorb minor displacements caused by wind vibration or vibration, improve the installation stability of the linear light, and at the same time isolate dissimilar metals from direct contact with the L-shaped support strip 17 and the extension 16, avoiding the risk of potential difference corrosion between dissimilar metals.

[0050] Furthermore, the end of the L-shaped support bar 17 is provided with a wire hole 174, which facilitates the routing of wires from inside the irregular hyperboloid curtain wall unit to the linear light, thus avoiding the exposure of the wires.

[0051] In summary, this utility model achieves high-precision and stable forming of complex hyperboloids by using segmented curved sheet material 1, a bidirectional rigid constraint linkage system (linkage of first link 4, second link 5, and third link 6), and rib plate 3 for coordinated positioning, combined with the reinforcement structure design of sharp corner 2 and edge flange design. At the same time, it integrates hidden linear lights, taking into account both unique shape and functional practicality, significantly improving deformation resistance, assembly efficiency, and aesthetics, and meeting the dual requirements of curtain walls for high-complexity appearance and structural reliability.
