Description

Technical Field

[0001] This application relates to the field of building construction, specifically to a hyperboloid canopy. Background Technology

[0002] In the fields of architecture and landscape design, awnings, as a common functional structure, are widely used at building entrances, above windows, or in outdoor corridors, serving to provide shade, rain protection, and decoration. Among them, arched awnings are particularly favored because of their beautiful streamlined appearance, which blends better with modern architectural aesthetics. Furthermore, their arched structure offers advantages in drainage and wind resistance.

[0003] Existing architectural curved canopies typically consist of a curved main keel (or arch beam) made of metal (such as steel or aluminum alloy), secondary keels, and translucent or opaque panels (such as tempered glass, polycarbonate sheets, or metal sheets) covering the keels. The construction method generally involves prefabricating the curved keel components in a factory, transporting them to the site for assembly and fixing, and finally installing the panels.

[0004] Although existing curved canopies have been widely used, there are still some long-standing technical defects in their design, manufacturing, and installation that have hindered further performance improvements and the expansion of their application scope.

[0005] Based on the applicant's in-depth research and analysis, the existing architectural curved canopy has at least the following technical shortcomings: Insufficient structural stability and wind uplift resistance: Especially for arched canopies with large spans or significant overhangs, the connection between the canopy and the main structure is often simple, lacking effective tensile and negative wind pressure resistance measures. Under strong winds, especially in areas with negative wind pressure, the canopy is prone to vibration, deformation, or even partial collapse, posing a safety hazard.

[0006] The drainage design has flaws: Traditional arched canopies rely on the natural slope of the panels or simple drainage holes for drainage. Inaccurate control of the curvature or improper treatment of the joints can easily lead to poor drainage, causing water accumulation and leakage. In the long run, it can also cause dirt to accumulate, affecting the aesthetics and structural durability.

[0007] High precision requirements for manufacturing and installation, and significant construction challenges: The processing of curved components requires a high level of craftsmanship, and alignment during on-site assembly is difficult, easily leading to misalignment, inconsistent curvature, and other problems. This not only affects the appearance but may also result in inadequate sealing. This typically prolongs the construction period and makes cost control less manageable.

[0008] Maintenance and partial replacement are difficult: the connection between the panel and the keel is often fixed. Once a panel is damaged, the replacement process is complicated and may involve the removal of adjacent components, resulting in high maintenance costs. Utility Model Content

[0009] The purpose of this invention is to provide a hyperboloid canopy to solve the technical problems mentioned in the background art.

[0010] To achieve the above objectives, the present invention adopts the following technical solution: A hyperboloid canopy, characterized in that it comprises a steel frame, diagonal tie members, an upper glass cladding, and a lower aluminum plate cladding. Both the upper glass cladding and the lower aluminum plate cladding are arc-shaped structures. The steel frame includes longitudinally spaced right-angled steel frames, with each right-angled steel frame corresponding to a single diagonal tie member. The hypotenuse of the right-angled steel frame is an inwardly concave arc-shaped rod. The diagonal tie members connect the right-angled bottom edge of the right-angled steel frame to the curtain wall steel keel on the structural wall. Each tie member includes a central round steel and connecting steel members at both ends of the central round steel. The connecting steel members include welded steel plates welded to embedded parts in the structural wall, clamps bolted to both sides of the welded steel plates, and end plates welded to both ends of the central round steel. The end plates are fixedly connected to the clamps. The upper glass cladding and the lower aluminum plate cladding are respectively located on the top and bottom surfaces of the diagonal edges of the steel frame. Several glass units and aluminum plate units are connected to form an arc-shaped structure.

[0011] More preferably, the right-angle steel frame includes vertically arranged L-shaped square steel members, horizontal square steel members, and concave arc-shaped members connected to the extended ends of the vertical and horizontal square steel members. It also includes several transverse members connected between the vertical square steel members and the concave arc-shaped members, several vertical members connected between the concave arc-shaped members and the horizontal square steel members, and several oblique members connected between the transverse members and between the transverse members and the horizontal square steel members.

[0012] Furthermore, the upper part of the concave arc-shaped member extends towards the structural wall and is fixed to the structural wall via angle brackets.

[0013] Furthermore, the curvature of the top and bottom surfaces of the canopy is varied by changing the height of the vertical square steel members, the length of the horizontal square steel members, and their relative positions to the right-angled bases of the adjacent steel frames.

[0014] Furthermore, longitudinal connecting rods are provided between the concave arc-shaped members of the adjacent steel frame, and the concave arc-shaped members and longitudinal connecting rods form the keel of the large canopy. The upper glass cladding includes adjusting pads, glass subframes, aluminum alloy pressure plates, and shaped aluminum plates.

[0015] In addition, the bottom aluminum panel includes a U-shaped component and an aluminum single panel. The U-shaped component is fixed to the bottom surface of the steel frame by screws, and the end of the aluminum single panel is bent and inserted into the U-shaped component and fixed by screws.

[0016] More preferably, the right-angled steel frame has a drainage groove at the end of the right-angled bottom edge extending outward. The drainage groove includes a steel square tube support, stainless steel plate groove walls on both sides of the drainage groove, and aluminum single-panel with aluminum plate cladding at the bottom is laid upward until it connects with the stainless steel plate groove wall.

[0017] Compared with the prior art, this utility model has the following features and beneficial effects: This application employs a modular right-angle steel frame combined with diagonal tie members, which offers technical advantages in enhancing overall structural stability and wind resistance. It solves the technical problems of weak connections between traditional canopies and the main structure, leading to instability under negative wind pressure. Specifically, each longitudinally spaced right-angle steel frame corresponds to a diagonal tie member. This tie member, through a central round steel section and connecting steel components (welded steel plates, clamps, and end plates) at both ends, firmly connects the right-angled base of the canopy's steel frame to the curtain wall steel keel of the structural wall, forming an effective force transmission path. This significantly improves the canopy's wind resistance, especially its ability to withstand negative wind pressure.

[0018] This application employs a technical solution with curved surfaces on both the top and bottom, and an adjustable frame. This offers the technical advantage of achieving a precise hyperboloid shape and balancing positive and negative wind pressure, solving the technical problems of traditional canopies' limited design and wind pressure resistance. By adjusting the height of the vertical square steel members, the length of the horizontal square steel members, and their relative positions, the curvature of the canopy's top (glass finish) and bottom (aluminum finish) can be flexibly controlled, forming a smooth hyperboloid. This design, with curved surfaces at both the top and bottom, helps balance the positive and negative pressures on the structure under wind loads, improving its stress state.

[0019] This application employs a technical solution that uses angle brackets to fix the upper part of the concave arc-shaped members to the wall and sets up longitudinal connecting rods. This solution has the technical advantage of further improving the overall integrity and lateral stability of the frame, and solves the technical problem that large-span canopy keels are prone to lateral deformation or torsion. The angle brackets provide auxiliary support at the upper end, while the longitudinal connecting rods connect adjacent arc-shaped members into a whole, forming a large canopy keel system with excellent spatial stress performance.

[0020] This application employs a technical solution of installing a stainless steel drainage channel at the end of a right-angled base. This solution offers advantages such as organized drainage, improved durability and aesthetics, and solves the technical problems of traditional awnings, including water accumulation, leakage, and corrosion of drainage components. The drainage channel is supported by steel square tubing and has stainless steel plate walls. An aluminum plate veneer is laid upwards at the bottom to connect with it, ensuring that rainwater can be smoothly channeled into the drainage system. The stainless steel material also extends the service life of the drainage channel.

[0021] This application adopts a standardized steel frame and connectors, and a modular installation solution for the decorative finish. This approach significantly improves processing accuracy, reduces on-site construction difficulty and maintenance costs, and solves the technical problems of difficult on-site assembly and inability to guarantee accuracy in traditional curved canopies. The main steel components (such as square steel rods, round steel, and connectors) can be prefabricated in the factory and assembled on-site as modules, ensuring the accuracy of the final curvature. The upper glass finish is installed using adjusting shims, subframes, and pressure plate systems, while the bottom aluminum plate is fixed using U-shaped fittings and bent ends, all facilitating adjustment and partial replacement.

[0022] In summary, this utility model, through the above-mentioned integrated technical solution, not only effectively overcomes the defects of existing arched canopies in terms of structural safety, drainage performance, construction accuracy, and maintenance convenience, but also improves economic benefits and promotional value through modular design, demonstrating significant practicality and innovation.
