Description

Technical Field

[0001] This invention relates to the field of decoration and renovation technology, and in particular, to a composite suspended ceiling structure with irregular curved surfaces. Background Technology

[0002] The decoration industry is currently developing towards industrialized modular installation. Generally speaking, ceiling decoration is a common decoration method used in interior design, which can increase the sense of layering in the interior space and play a role in beautification.

[0003] High-ceiling curved ceilings are common in the decoration and renovation industry. However, in interior design, the materials used for high-ceiling curved surfaces are basically the same. Moreover, the cumulative error adjustments that occur during construction in high spaces, as well as the visual effect after completion, pose a huge challenge to the management capabilities of the entire project management team. In the base construction stage, in order to meet the design requirements, the steel frame base needs to be welded and fixed according to the curved shape. However, in high spaces, the occurrence of errors and cumulative errors poses a considerable challenge to the installation of decorative surfaces. Adjusting the steel frame base again is often time-consuming, labor-intensive, and involves a huge workload. Long-term high-altitude work also indirectly increases the project's high-altitude work safety management costs.

[0004] Therefore, the installation design of curved ceiling structures in large spaces is very important. For example, Chinese invention patent CN113107134A discloses an installation design structure for an ultra-large irregular curved ceiling, belonging to the field of building decoration technology. It includes a prefabricated ceiling mechanism, a prefabricated conversion layer mechanism, and a clamp hanging mechanism. The clamp hanging mechanism is fixedly connected to the top base layer, the top of the prefabricated conversion layer mechanism is fixedly connected to the clamp hanging mechanism, and the prefabricated ceiling mechanism is snapped onto the bottom of the prefabricated conversion layer mechanism. The above invention forms a prefabricated ceiling mechanism by pre-installing curved panels, horizontal keels, and vertical keels on the ground, and forms a prefabricated conversion layer mechanism by pre-installing fixed square tubes, second-stage hangers, and fixed slide rails on the ground. The prefabricated conversion layer mechanism is fixed to the clamp hanging mechanism, and the prefabricated ceiling mechanism is quickly snapped onto the prefabricated conversion layer mechanism. The overall modular installation makes the operation simple and convenient, avoids deformation of large-span curved ceilings, and has good decorative aesthetics.

[0005] However, the installation design structure of the above-mentioned extra-large irregular curved ceiling still has the following problems: Although a pre-installed structure is adopted, its pre-installed structure is complex, lacks standardization, and still uses a large number of steel structure frames for installation, resulting in heavy weight, poor hoisting safety, and it can only be used for installation on ceilings with specific curvatures. The installation error of curved ceilings is large, and it cannot adapt to the installation of ceilings with different curvatures. Moreover, it is still a single ceiling structure, and different ceiling locations may have different curvatures, resulting in poor aesthetics and poor applicability.

[0006] Therefore, in order to solve the above problems, it is necessary for us to design a reasonable and efficient irregular curved surface combination ceiling structure. Summary of the Invention

[0007] The purpose of this invention is to provide a composite ceiling structure with irregular curved surfaces. Its structure is simple; it involves constructing a combined ceiling structure of curved and saddle-shaped panels on the top of large buildings.

[0033] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0034] Techniques, methods, and systems known to those skilled in the art may not be discussed in detail, but where appropriate, they should be considered part of this specification.

[0035] Example 1: As Figures 1 to 8 The illustration shows only one embodiment of the present invention. A non-circular curved ceiling structure includes a curved ceiling 1 and a saddle-shaped ceiling 2. The curved ceiling 1 includes a first steel beam 11, a functional keel 12 connected to the first steel beam 11, a hanging keel 13 connected to the functional keel 12, and a functional ceiling panel 14 connected to the hanging keel 13. The end of the functional keel 12 is connected to the end of another functional keel 12 through an adjusting member. The saddle-shaped ceiling 2 includes a second steel beam 21, a first support frame 23 connected to the second steel beam 21, a decorative panel keel 25 for connecting to the first support frame 23, and a decorative panel 26 hung on the decorative panel keel 25. The decorative panel 26 is a saddle-shaped panel.

[0036] In this invention, the irregular curved surface combined ceiling structure is mainly used in large ceiling spaces such as large shopping mall ceilings, high-speed rail stations, and airport waiting halls, hereinafter collectively referred to as architectural ceilings. In these architectural ceilings, due to the need for varying heights and zoning in some areas, it is often necessary to design various curved ceilings or even (quasi-)spherical ceilings. This invention is suitable for the above-mentioned irregular curved surface ceilings. Moreover, this invention adopts the form of combining curved ceiling 1 and saddle ceiling 2 to form a combined ceiling structure, which is not only beautiful and grand, but also allows for stable, safe and efficient ceiling installation for various irregular curved surfaces.

[0037] First, there is the curved ceiling 1, which includes a first steel beam 11, a functional keel 12 connected to the first steel beam 11, a hanging keel 13 connected to the functional keel 12, and a functional ceiling panel 14 connected to the hanging keel 13. The end of the functional keel 12 is connected to the end of another functional keel 12 through an adjusting member.

[0038] Specifically, the functional keel 12 is hung on the first steel beam 11 by the first hanger 15, and the two functional keels 12 connected end to end are adjusted in three-dimensional space by the adjustment component, so that the curvature of the entire ceiling can be adjusted at the functional keel 12 layer. Then, the hanging keel 13 is hung again below the functional keel 12 by the second hanger 16. By installing long strip functional ceiling panels 14 on the hanging keel 13, a grid-like curved ceiling structure is formed.

[0039] Secondly, there is the saddle-shaped top 2, which includes a second steel beam 21, a first support frame 23 connected to the second steel beam 21, a decorative panel keel 25 for connecting to the first support frame 23, and a decorative panel 26 hung on the decorative panel keel 25. The decorative panel 26 is a saddle-shaped panel.

[0040] Specifically, a first support frame 23 is set on the second steel beam 21, and then the mesh-like decorative panel keel 25 is hung on the first support frame 23. The decorative panel keel 25 can be tilted at will, so that decorative panels 26 with tilt angles are hung on the decorative panel keel 25 to form a saddle-shaped saddle-shaped ceiling 2.

[0041] Finally, the curved ceiling 1 and the saddle ceiling 2 are combined, as follows: Figure 1 As shown, multiple functional ceiling panels 14 are arranged at different heights to form a basic curved structure. Then, a saddle ceiling 2 is set at predetermined intervals on the lower side of the curved ceiling 1, so that the curvature of the upper side of the saddle ceiling 2 is the same as the curvature of the lower side of the curved ceiling 1, forming two cooperating ceilings, effectively dividing the long curved ceiling 1 into multiple areas.

[0042] A certain gap is left between the decorative panel 26 and the functional ceiling panel 14 to allow for thermal expansion and contraction and vibration in large spaces, so that the curved ceiling 1 and the saddle ceiling 2 can be independent of each other but can be combined to form a ceiling structure.

[0043] In special cases: a skylight 5 is provided between the two curved ceiling 1s, and the saddle ceiling 2 is positioned precisely between these two curved ceiling 1s. The sides of the saddle ceiling 2 can be combined with the two curved ceiling 1s; alternatively, two curved ceiling 1s with different curvatures can even be provided on each side of the saddle ceiling 2. Furthermore, the functional ceiling panel 14 of one of the curved ceiling 1s can be bent again to form a staggered, layered curved ceiling structure, such as... Figure 2 As shown, this allows the curved ceiling 1 to form a versatile and adjustable irregular curvature ceiling. At the same time, the saddle ceiling 2 can effectively divide and coordinate the versatile curved ceiling 1 to form a beautiful and safe irregular curved combined ceiling structure.

[0044] It should be noted that since the curved ceiling 1 and the saddle ceiling 2 are combined, the installation steps for this irregular curved combined ceiling structure are as follows:

[0045] S1: First, the first hanger 15 is hung on the first steel beam 11 via the hanger 111;

[0046] S2: On the ground, the functional keel 12 and the transition keel 121 are connected by the first clamp 122. Then, the second clamp 123 is installed on the transition keel 121 and the second hanger 16 is connected. The hanging keel 13 is fixed to the bottom of the second hanger 16 by bolts. The hanging opening 141 of the functional ceiling panel 14 is inserted into the hanging hook plate 131 set below the hanging keel 13 to form an integral ceiling hanging structure.

[0047] S3: Then lift the overall ceiling hanging structure formed in step S2 to the first hanger 15 on the first steel beam 11 to complete the one-time hanging of the ceiling hanging structure;

[0048] The above completes the hoisting of the curved ceiling 1; and the entire ceiling hanging structure is lifted and fixed at one time, reducing the time for high-altitude installation and increasing safety.

[0049] S4: Install the first support frame 23 on the second steel beam 21 (install the second support frame 24 on the third steel beam 22);

[0050] S5: After the decorative panel keel 25 is welded as a whole, it is lifted as a whole to the first support frame 23 (and / or the second support frame 24) and installed on the first support frame 23 (and / or the second support frame 24) through the Z-shaped connector 28;

[0051] The above completes the hoisting of the top 2 of the saddle crane (excluding the decorative panel 26);

[0052] S6: Based on the curvature of the functional ceiling panel 14, prepare a decorative panel 26 of the corresponding shape (mainly by cutting the edge of the decorative panel 26 on the side close to the functional ceiling panel 14), so that the arc surface of the upper edge of the decorative panel 26 matches the lower side surface of the functional ceiling panel 14 with the same curvature.

[0053] The above completes the installation of the irregular curved surface combined ceiling structure of the present invention.

[0054] This invention discloses a composite ceiling structure with irregular curved surfaces. The structure is simple, combining curved and saddle-shaped ceiling panels on the top of large buildings. The curved ceiling panels can be selected in various shapes to suit different building forms. The saddle-shaped ceiling panels not only allow for quick adjustment of the installation accuracy of the curved ceiling panel base but also provide spatial division and positioning for the curved ceiling panel. The overall structure is aesthetically pleasing and impressive, with high prefabricated installation efficiency. It is suitable for various types of buildings, allowing for free adjustment of the curvature during installation. The ceiling structure is lightweight, and the overall lifting and hoisting significantly reduces high-altitude work time, while also ensuring high installation safety.

[0055] Example 2, still as Figures 1 to 8 The illustration shown is merely one embodiment of the present invention. Based on Embodiment 1, the structural design of the curved ceiling 1 also includes the following:

[0056] The adjusting component includes an adjusting main plate 31 and an adjusting secondary plate 32 connected to the adjusting main plate 31. The adjusting secondary plate 32 is connected to the adjusting main plate 31 by a first bolt 33, and the adjusting secondary plate 32 rotates around the first bolt 33. The adjusting secondary plate 32 is provided with a second bolt 34 for connecting with the functional keel 12 and a bolt groove 35 for facilitating the sliding of the second bolt 34. The extending direction of the bolt groove 35 is the same as the extending direction of the functional keel 12, and it is used to adjust the position and included angle between the two functional keels 12 connected end to end.

[0057] It should be noted that a third bolt is also provided on the side of the first bolt 33 near the adjusting sub-plate 32. The adjusting main plate 31 is also provided with an arc-shaped auxiliary hole 331 to facilitate the sliding of the third bolt. The center of the arc structure of the auxiliary hole 331 is located at the first bolt 33, so that the third bolt can slide on this arc-shaped auxiliary hole 331. After the included angle of the two functional keels 12 connected end to end is adjusted, the third bolt is tightened. In this way, the first bolt 33 and the third bolt work together to complete the connection between the adjusting main plate 31 and the adjusting sub-plate 32. Conversely, when it is necessary to adjust the included angle between the two functional keels 12 connected end to end, it is only necessary to loosen the third bolt (it will not be unscrewed, just loosened), and then rotate the angle between the adjusting main plate 31 and the adjusting sub-plate 32. At this time, the third bolt just slides on the auxiliary hole 331, and the included angle between the two functional keels 12 connected end to end can be adjusted again until the adjustment is completed. Finally, tighten the third bolt to complete the fixation.

[0058] Of course, the adjusting component is connected to the first steel beam 11 via the first suspension rod 15. The adjusting main plate 31 is provided with a vertical cylinder 36 for connecting to the lower end of the first suspension rod 15, and the first steel beam 11 is provided with a hanging component 111 for connecting to the upper end of the first suspension rod 15.

[0059] In this way, the height of the functional keel 12 can be adjusted by connecting the vertical cylinder 36 to the first hanging rod 15; the included angle between the two connected functional keels 12 can be adjusted by rotating the adjustment sub-plate 32 around the first bolt 33, and the distance between the two connected functional keels 12 can be adjusted by sliding the second bolt 34 in the bolt groove 35; thus, functional keels 12 with different heights, positions and tilt angles can be set, providing a basis for adjusting the curvature of the functional ceiling panel 14 suspended below them.

[0060] In this invention, a transition keel 121 is mounted on the functional keel 12, the hanging keel 13 is connected to the transition keel 121 via a second hanger 16, the transition keel 121 is connected to the functional keel 12 via a first clamp 122, and a second clamp 123 is provided on the transition keel 121 for connecting to the upper end of the second hanger 16.

[0061] Additionally, a mounting hook plate 131 is provided below the mounting keel 13, and the functional ceiling panel 14 consists of multiple ceiling strips forming a grid structure. The upper end of each ceiling strip has a mounting opening 141 for connecting to the mounting hook plate 131. Figure 5 As shown, both the mounting keel 13 and the functional ceiling panel 14 have at least a portion that is arc-shaped.

[0062] Example 3, still as Figures 1 to 8 The illustration shown is merely one embodiment of the present invention. Unlike Embodiment Two, the structural design of the top 2 of the saddle crane, based on Embodiment One, includes the following additional details:

[0063] The first support frame 23 includes an L-shaped hanging component 231 and a horizontal keel 232 connected to the L-shaped hanging component 231. The second steel beam 21 is provided with a third clamp 211 for connecting to the L-shaped hanging component 231.

[0064] Additionally, the top of the saddle crane 2 also includes a third steel beam 22 located below the second steel beam 21 and a second support frame 24 connected to the third steel beam 22; a joint keel 27 is provided between the first support frame 23 and the second support frame 24.

[0065] Furthermore, in extra-large building ceiling spaces where stability is particularly required, a third support frame 241 is provided between the first support frame 23 and the second support frame 24 to further enhance ceiling stability. The first support frame 23, the third support frame 241, and the second support frame 24 are all connected by a joint keel 27.

[0066] In this invention, the decorative panel keel 25 includes a horizontal keel 251 and a vertical keel 252; the horizontal keel 251 is connected to the horizontal keel 232 via a zigzag connector 28; and the decorative panel 26 is connected to the vertical keel 252.

[0067] It should be noted that the U-shaped connector 28 includes a first U-shaped clamp 281 connected to the horizontal keel 232 and a second U-shaped clamp 282 connected to the transverse keel 251. The first U-shaped clamp 281 has its opening facing downwards, and the second U-shaped clamp 282 has its opening facing upwards. The wing plates on both sides of the lower end of the first U-shaped clamp 281 and the wing plates on both sides of the upper end of the second U-shaped clamp 282 extend in roughly perpendicular directions. The wing plates on the lower end of the first U-shaped clamp 281 and the wing plates on the upper end of the second U-shaped clamp 282 are fixedly connected by a third bolt 283. Figure 7 As shown.

[0068] In one embodiment of the present invention, a C-shaped buckle 253 is provided on the longitudinal keel 252, and an insert plate 261 for inserting into the C-shaped buckle 253 is provided on the decorative panel 26, such as... Figure 8 As shown, this avoids the need for nailing the decorative panel 26, improves its removability, and allows for adjustment of the tilt angle of the decorative panel 26 by controlling the length of the insert plate 261 and the depth of insertion into the C-shaped buckle 253.

[0069] It should be noted that, in order to reduce the weight of the entire combined ceiling, in this application, apart from the steel beams, the functional keel 12, transition keel 121, hanging keel 13, horizontal keel 232, and decorative panel keel 25 are all made of stainless steel square tubing, which is not only lightweight and easy to install, but also has high structural strength; however, with the development of technology, the above-mentioned keel structure can also be made of other alloy materials or high-strength lightweight polymer materials.

[0070] Finally, the decorative panel 26 also includes a bottom decorative panel 29. The bottom of the longitudinal keel 252 is provided with a vertical rod 254, and the bottom of the vertical rod 254 is provided with a stepped ceiling decorative strip 255. The bottom decorative panel 29 is connected to the stepped ceiling decorative strip 255. The transverse keel 251 is provided with a reinforcing hanger 256 for connecting to the bottom decorative panel 29.

[0071] This invention discloses a composite ceiling structure with irregular curved surfaces. The structure is simple, combining curved and saddle-shaped ceiling panels on the top of large buildings. The curved ceiling panels can be selected in various shapes to suit different building forms. The saddle-shaped ceiling panels not only allow for quick adjustment of the installation accuracy of the curved ceiling panel base but also provide spatial division and positioning for the curved ceiling panel. The overall structure is aesthetically pleasing and impressive, with high prefabricated installation efficiency. It is suitable for various types of buildings, allowing for free adjustment of the curvature during installation. The ceiling structure is lightweight, and the overall lifting and hoisting significantly reduces high-altitude work time, while also ensuring high installation safety.

[0072] This invention is not limited to the specific embodiments described above, and various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements made to the above embodiments based on the technical essence of this invention should be included within the scope of protection of this invention.
