Abstract
Description
Technical Field
[0001] This utility model relates to the field of building ceiling technology, and in particular to a hyperboloid large roof ceiling structure. Background Technology
[0002] With the development of modern building technology, large-span, irregularly shaped curved surfaces (such as hyperboloids) interior ceiling structures are increasingly widely used in large public buildings (such as airports, stadiums, and convention centers). These ceiling structures not only bear decorative functions, but also need to meet various usage requirements such as acoustics, optics, and fire protection, and require the installation and maintenance of a large number of electromechanical equipment (such as lighting fixtures, sprinkler heads, and broadcasting systems).
[0003] Currently, traditional ceiling framing systems are commonly used to implement complex hyperboloid ceilings. However, existing solutions have several drawbacks: First, traditional ceiling framing systems (such as simple planar trusses or grid keels) have relatively limited structural forms and are poorly adaptable to complex and varied irregular hyperboloid shapes. Achieving specific curved surface shapes often requires complex on-site fabrication and adjustments, making it difficult to meet the implementation requirements of complex designs and resulting in low structural efficiency. Second, the interior space of large ceilings typically requires access walkways for the installation, commissioning, and subsequent maintenance of electromechanical equipment above the ceiling. Traditionally, the access walkway system and the load-bearing ceiling framing system are independently designed. This separate design causes the access walkway itself and its supporting structure to become additional loads, significantly increasing the overall weight of the ceiling structure and even the main structure, which is particularly detrimental to large-span buildings. Furthermore, in some buildings, the installation space for the ceiling system is very limited due to constraints imposed by the upper main structure (such as a roof grid). Within such a complex and confined space, arranging and installing traditional, independent access ramps becomes extremely difficult, making subsequent maintenance work challenging. Furthermore, the complex on-site installation process for both systems (framework and ramps), coupled with a long construction period, also introduces more safety hazards.
[0004] Therefore, the industry urgently needs a new type of ceiling structure that can flexibly adapt to the design requirements of complex and irregular hyperboloids, solve the problems of heavy weight and difficulty in maintenance in small spaces caused by traditional maintenance walkway systems, and simplify construction and shorten the construction period.

[0005] The purpose of this utility model is to overcome the shortcomings of existing technologies and to propose a hyperboloid large roof ceiling structure. To achieve the above objective, the embodiments of this utility model adopt the following technical solution: This utility model embodiment proposes a hyperboloid large roof ceiling structure, including: an outer frame, which is connected to the ground through support columns, and has a main support structure extending inward; an inner frame connected to the outer frame, the outer periphery of which is connected to the outer frame, and has a circumferentially connected inner support structure, wherein both the inner support structure and the main support structure are provided with interconnected maintenance walkways; and decorative surfaces provided on the top surfaces of the outer and inner frames, as well as on the outer and inner frames.

[0008] Preferably, the interior decorative surface, located between the main support structure and the inner support structure and connected to the outer and inner frames, includes multiple sets of lamps, a suspension structure, a light steel keel, and a metal veneer. The light steel keel is connected to the outer lower main beam and the inner lower main beam, and the metal veneer is connected to the light steel keel through the suspension structure. A longitudinal difference is provided between adjacent metal veneers, and the lamps are located between two sets of adjacent metal veneers.
[0009] Preferably, a fall arresting cable is installed between the lamps, and the fall arresting cable is connected to the light steel keel.
[0010] Preferably, the main support structure includes a supporting outer frame beam, three or more sets of horizontal supports and diagonal supports matching the horizontal supports, the maintenance walkway is connected to the horizontal supports, and the horizontal supports above and below the maintenance walkway are each connected to the outer upper main beam and the outer lower main beam through supports.
[0011] Preferably, the support includes: a connecting channel steel, a conversion component, and an arc-shaped galvanized steel plate. The horizontal support has an installation groove adapted to the connecting channel steel. The connecting channel steel is located in the installation groove and welded at the edge of the installation groove. The arc-shaped galvanized steel plate is connected to the upper main beam and / or the outer lower main beam. The conversion component is connected between the arc-shaped galvanized steel plate and the connecting channel steel.
[0012] Preferably, the maintenance walkway includes a steel mesh and a movable ladder, which are respectively connected to horizontal supports.

[0015] Beneficial effects: This utility model provides a hyperboloid large roof ceiling structure that systematically integrates the maintenance walkway system into the main support structure and the inner support structure, making them interconnected. This effectively overcomes the limitations of existing technologies where the maintenance walkway and ceiling frame are independent, resulting in excessive structural weight and difficulties in maintenance within confined spaces with complex shapes. Compared with existing technologies, the support structure system of this utility model has the dual functions of supporting the shape and providing maintenance access, eliminating the need for an additional independent walkway system and significantly reducing the overall weight of the ceiling structure. More importantly, through the combined design of the outer frame, inner frame, and main and inner support structures, this structure is not only flexible in form and can effectively adapt to the needs of complex hyperboloid shapes, but its internally connected maintenance walkway also ensures convenient and safe maintenance work even in complex ceiling spaces, solving the problem of maintenance in confined spaces and improving the space utilization and practicality of the structure.

It should be noted that the embodiments described herein are only some examples of this utility model, and not all of them.

[0020] Example This utility model discloses a hyperboloid large roof ceiling structure 10, aiming to solve the problems of existing traditional frame systems for irregular hyperboloid large roof ceilings, which have a single structural form, cannot meet the needs of complex shapes, and have excessive structural weight and difficulty in maintenance in confined spaces due to the independent setting of the maintenance walkway and frame. This embodiment, through an innovative combined frame design, integrates the maintenance walkway 17 with the main support structure 14 and the inner support structure 16, achieving a balance between lightweight structure, flexible shape, and convenient maintenance. It is especially suitable for large irregular hyperboloid ceiling designs with complex existing conditions and limited space.
[0021] To more clearly illustrate the technical solutions of the embodiments of this utility model, the following will be combined with the accompanying drawings. Figure 1 To be continued Figure 6 A detailed explanation is provided. (Refer to...) Figure 1 , Figure 2 and Figure 6 This embodiment discloses a hyperboloid large roof ceiling structure 10. The basic load-bearing system of this structure includes a large-span outer frame 11. (Refer to...) Figure 6 The outer frame 11 is stably connected to the ground 13 by multiple support columns 12, forming the external load-bearing boundary and outline of the entire ceiling structure.
[0022] Depend on Figure 1 and Figure 2 As shown, multiple sets of main support structures 14 are provided on the outer frame 11, radiating inwards. These main support structures 14 act as a radially partial load-bearing skeleton, capable of bearing the central load of the ceiling and transferring it to the main components of the outer frame 11. The ceiling structure 10 also includes an inner frame 15. This inner frame 15 is located in the central region of the ceiling structure 10 (e.g., the boundary used to form a skylight atrium). Figure 1 and Figure 2 As shown, the outer periphery of the inner frame 15 is connected to the inner end of each group of main support structures 14, thereby achieving overall connection and force sharing between the main support structures 14 and the outer frame 11.
[0023] On the inner frame 15, there are also circumferentially connected inner support structures 16. These inner support structures 16 are used to strengthen the circumferential stiffness of the inner frame 15 and to support the ceiling finish in the central area.
[0024] A key technical feature of this embodiment is that the maintenance walkway 17 is located inside the main support structure 14 and the inner support structure 16. Furthermore, the maintenance walkway 17 located in the main support structure 14 and the maintenance walkway 17 located in the inner support structure 16 are interconnected. This integrated design allows the support structure itself to become a maintenance passage, enabling maintenance personnel to move and work within the support structure without the need for an additional independent walkway system. This significantly reduces the overall weight of the ceiling structure, which is particularly important for large-span buildings, and also perfectly solves the maintenance challenges in complex, irregularly shaped, and confined spaces. Finally, the ceiling structure 10 also includes a top surface 18 (such as...) located on top of the outer frame 11 and the inner frame 15. Figure 6 As shown), and the decorative surface 19 suspended below the frame and support structure (as shown). Figure 2 and Figure 6 As shown in the figure, together they constitute a complete ceiling system.
[0025] As a preferred embodiment, in order to efficiently construct a passageway for accommodating the maintenance walkway 17 within the frame and support structure, and to achieve a balance between lightweight structure and high load-bearing capacity, the frame and support structure of this embodiment preferably adopts a truss structure.
[0026] Reference Figure 2 and Figure 6 The outer frame 11 specifically includes an upper outer main beam 111 (as an upper chord), an lower outer main beam 112 (as a lower chord), and an external connecting beam 113 (such as a diagonal web member and a vertical member) for connecting the upper and lower main beams.
[0027] Similarly, the inner frame 15 specifically includes an inner upper main beam 151 (upper chord), an inner lower main beam 152 (lower chord), and an internal connecting beam 153 (web member) for connecting the upper and lower main beams.
[0028] The main support structure 14 and the inner support structure 16 also adopt a similar truss structure.
[0029] With this double-layer main beam and truss design, the maintenance walkway 17 can be conveniently located in the abdominal space between the outer upper main beam 111 and the outer lower main beam 112, and between the inner upper main beam 151 and the inner lower main beam 152, allowing maintenance personnel to pass safely within the abdominal space of the truss.
[0030] Reference Figure 2 and Figure 4 To achieve a specific architectural aesthetic effect, the bottom ends of the main support structure 14 and the inner support structure 16 preferably extend downward and pass through the decorative surface 19, exposing part of their structure below the decorative surface 19.
[0031] Accordingly, the decorative surface 19 is specifically divided into two parts in terms of shape: one is the beam decorative surface 191 that is set and wrapped around the main support structure 14 and the inner support structure 16 (e.g., Figure 4 As shown), it is used to beautify and cover the exposed supporting structure trusses; secondly, it is used for the interior decorative surface 192 (as shown) between adjacent main supporting structures 14 and / or inner supporting structures 16. Figure 3 (As shown). The interior decorative surface 192 is connected to the lower main beams (i.e., the outer lower main beam 112 and the inner lower main beam 152) of the outer frame 11 and the inner frame 15 via connectors, forming the main visible ceiling of the suspended ceiling. Its shape follows the curve of the lower main beam to form the desired hyperboloid effect.
[0032] To further enrich the decorative effect of the suspended ceiling and integrate functional components (such as lighting), refer to Figure 3 (Right now Figure 2 (Enlarged view of part A) shows the optimized design of the structure of the interior decorative surface 192.
[0033] Specifically, the interior decorative surface 192 includes multiple sets of functional and structural components: a light steel keel 192c as the base framework, a suspension structure 192b for connecting the decorative panels, a metal veneer 192d as the final decorative layer, and a lighting fixture 192a for illumination. During installation, the light steel keel 192c, as the base framework defining the hyperboloid shape, is first connected to the upper outer lower main beam 112 and inner lower main beam 152 (e.g., via hangers or special connectors) via hangers or special connectors. Figure 2 Connect the lines shown in the diagram to precisely define the complex design lines of the hyperboloid ceiling.
[0034] Subsequently, the metal veneer 192d (e.g., irregularly shaped perforated aluminum panels or honeycomb aluminum panels) is connected to the light steel keel 192c via a suspension structure 192b (e.g., a dedicated hook and hanger system). The advantage of using the suspension structure 192b is that it facilitates the installation and removal of individual veneer panels, making it easier to maintain equipment above the veneer (such as sprinkler heads, smoke detectors, etc.).
[0035] A unique design feature of this embodiment is the longitudinal difference between adjacent metal finishes 192d, creating a height difference in the radial or circumferential direction (or simultaneously) of the ceiling, resulting in a stepped, staggered arrangement. Utilizing the gap created by this longitudinal difference, light fixtures 192a (e.g., LED linear light strips or downlights) are cleverly installed between two sets of adjacent metal finishes 192d. This design creates a concealed, indirect lighting or linear lighting effect, with soft light that is visible but not the source, greatly enhancing the visual quality of the ceiling.
[0036] As an important safety preference measure, refer to Figure 3 In the vicinity of or between the light fixtures 192a, anti-fall cables 192e are also installed. One end of the anti-fall cable 192e (e.g., by bolts or clips) is fixed to the housing of the light fixture 192a or its mounting bracket, while the other end is securely connected to the upper light steel keel 192c or a higher-level structural beam (e.g., the inner lower main beam 152). This ensures that even if the conventional fasteners of the light fixture (such as screws or clips) fail due to vibration or aging, the light fixture 192a can be held in place by the cable and will not fall, thus effectively protecting the safety of personnel in the space below the ceiling.
[0037] To explain in detail how the main support structure 14 (and similar internal support structure 16) efficiently integrates the maintenance walkway 17, refer to... Figure 4 The main support structure 14 itself is designed as a three-dimensional truss structure with a certain height.
[0038] Specifically, it includes the supporting outer frame beam 141 as the upper and lower chords of the truss, multiple sets (e.g., 3 or more sets) of horizontal supports 142 distributed along the structural height direction (as the transverse struts of the truss), and diagonal supports 143 that match the horizontal supports 142 (as the web members of the truss), which together constitute a stable and lightweight load-bearing unit.
[0039] The maintenance walkway 17 (which may be composed of steel mesh 171) is directly laid and welded (or fixed by bolts) on a horizontal support 142 of a certain layer (usually the middle layer), so that the steel mesh 171 itself becomes a permanent component of the truss and participates in the structural stress, rather than an additional load.
[0040] To facilitate vertical passage for maintenance personnel between walkways at different elevations (e.g., at the walkway interface between the main support structure 14 and the inner support structure 16), refer to Figure 4 The maintenance walkway 17 preferably includes a movable ladder 172, which is also fixedly connected to the horizontal support 142 of the truss or the outer frame beam 141 of the support.
[0041] By directly connecting the steel mesh 171 and ladder 172 of the maintenance walkway 17 to components such as the horizontal support 142 of the truss, the functional integration and physical fusion of the maintenance system and the support system are perfectly realized.
[0042] In actual construction, the main support structure 14 (as a radial truss) needs to be connected to the outer frame 11 and the inner frame 15 (as a circumferential main beam). Especially when the circumferential main beams (such as the outer upper main beam 111, outer lower main beam 112, inner upper main beam 151, and inner lower main beam 152) are irregularly shaped curved components (such as large circular steel pipes), while the components of the support structure 14 (such as the horizontal support 142) are usually rectangular square tubes, the connection between the two becomes a technical challenge.
[0043] Therefore, in this embodiment, preferably, at least one set (i.e., one set above and one set below) of the horizontal supports 142 located above and below the maintenance walkway 17 is selected and connected to the outer upper main beam 111 and outer lower main beam 112 (or inner upper main beam 151 and inner lower main beam 152) through specially designed supports 20 to ensure the rigidity and reliability of load transfer.
[0044] Reference Figure 5 The support 20 has an ingenious structure and is specifically designed to solve the problem of irregular connection between square tubes (horizontal supports) and round tubes (main beams). The support 20 preferably includes: a connecting channel steel 201, a conversion component 202, and an arc-shaped galvanized steel plate 203.
[0045] The specific connection process is as follows: At the end of the horizontal support 142 (usually a square tube) of the main support structure 14, a mounting groove 144 that is adapted to the connecting channel steel 201 (e.g., C-shaped channel steel) is precisely cut in the factory. The connecting channel steel 201 is inserted into the mounting groove 144, and it is firmly fixed to the end of the horizontal support 142 by full welding at the edge of the mounting groove 144.
[0046] At the same time, the arc-shaped galvanized steel plate 203 is welded to the circumferential main beam ( Figure 5 The example in the middle is the inner upper main beam 151) pipe wall surface, the arc of the arc-shaped galvanized steel plate 203 is pre-processed to completely fit the arc of the outer diameter of the pipe wall of the main beam 151.
[0047] Finally, during on-site installation, the connecting channel steel 201 and the arc-shaped galvanized steel plate 203 are welded together using a sturdy steel plate (i.e., the transition piece 202). This method of transition via the support 20 ensures a clear and reliable load transfer path from the radial truss (14) to the circumferential main beam (15), greatly facilitating on-site assembly installation, avoiding complex on-site irregular cutting and welding, and guaranteeing construction quality.
[0048] As another preferred embodiment, refer to Figure 6 The top surface 18 of the suspended ceiling structure 10 was specifically designed to introduce natural lighting and enhance the building's sense of openness.
[0049] The top surface 18 preferably includes a curtain wall roof 181, a curtain wall skylight 182, and an electric sunshade 183.
[0050] The curtain wall roof 181 (e.g., a glass curtain wall or a metal roof) is connected to the top of the outer frame 11 and / or the inner frame 15 (e.g., the outer upper main beam 111 and the inner upper main beam 151) to form the roof enclosure of the building.
[0051] A skylight 182 is installed in a specific area of the curtain wall roof 181 (e.g., the central area above the inner frame 15). To dynamically adjust the intensity of light entering the room, an electric sunshade 183 is also installed below the skylight 182. This sunshade 183 (e.g., roller blind or venetian blind) is used to automatically control the opening and closing (i.e., shading or light transmission) of the skylight 182 according to the intensity of sunlight or user needs.
[0052] As another preferred structural reinforcement measure, refer to Figure 6To enhance the overall ceiling structure 10's resistance to horizontal forces (such as wind loads or seismic forces), a diagonal brace (not shown in the figure, but located at the connection between the top of the support column 12 and the outer frame 11) is added between the support column 12 and the outer frame 11. This diagonal brace creates a stable triangle at the connection point, significantly improving the overall stiffness and stability of the structure against horizontal thrust.
[0053] In summary, this utility model embodiment integrates the maintenance walkway 17 with the main support structure 14 and the inner support structure 16, and combines a double-layer truss frame (outer frame 11, inner frame 15), dedicated support 20 connectors, and a functional interior decorative surface 192. This not only effectively overcomes the defects of heavy structural weight, poor shape adaptability, and difficult maintenance in the prior art, but also achieves a highly efficient unity of lightweight structure, shape flexibility, and convenient maintenance. Furthermore, this modular structure is flexible and very easy to adopt a modular construction method of factory unit processing, on-site assembly, and hoisting, thereby significantly shortening the construction cycle of complex hyperboloid ceilings and reducing safety hazards of high-altitude operations.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
