Description

Technical Field

[0001] This utility model belongs to the field of transition layer ceiling technology, and in particular relates to a spherical grid hyperbolic transition layer ceiling structure. Background Technology

[0002] Gas stations, stadiums, and other large-span buildings typically employ spherical space frame structures for their roofs. A spherical space frame structure is a spatial structure formed by multiple members connected in a grid pattern via bolted ball joints. The top of the suspension rods of the ceiling transfer layer components are bolted to the ball joints, while the bottom connects to the ceiling frame. Existing ceiling structures use rigid connections between the ball joints and the ceiling frame, achieved through high-altitude welding of steel profiles. This results in several drawbacks. First, the threaded connections alone are insufficiently secure. The bolt holes on the balls are often too small to withstand significant tensile forces, failing to meet load-bearing requirements. Furthermore, the pre-drilled holes on the balls compromise the integrity of the space frame, affecting ceiling quality. Second, this type of space frame structure is far more complex to install than a planar structure due to the large number of members converging at the nodes. This leads to low labor efficiency, significant safety hazards, long construction periods, high costs, and a lack of material flexibility. Consequently, it no longer fully meets the requirements for rapid construction, green construction, and enhancing corporate competitiveness in ceiling transfer layer construction.

This structure achieves stability and safety through the use of a steel transition mechanism welded to a welded ball. The connection between the transition tube and the welded ball increases the available space, thereby increasing tensile strength and meeting load-bearing requirements. Simultaneously, it avoids pre-drilling bolt holes in the welded ball, ensuring its integrity and the quality of the ceiling. Furthermore, a clamp mechanism connects the longitudinal and transverse keels of the transition layer, eliminating the need for welding during construction. This clamp mechanism simplifies the construction process, improves efficiency, and reduces safety hazards.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a spherical grid hyperbolic transition layer ceiling structure, characterized in that: it includes a steel grid, a transition layer keel layer disposed below the steel grid, and a steel structure transition mechanism disposed between the steel grid and the transition layer keel layer;

[0011] This utility model has the following advantages compared with the prior art:

[0012] 1. This utility model achieves the stability and safety of the ceiling structure connection by using a steel structure conversion mechanism to weld the welding ball. The use of a transition tube and welding ball connection increases the reserved space, thereby increasing the tensile strength and meeting the load-bearing requirements. At the same time, it avoids reserving bolt holes on the welding ball, ensuring the integrity of the welding ball and the quality of the ceiling.

[0013] 2. This utility model utilizes a clamp mechanism to connect the longitudinal and transverse keels of the transition layer, thereby avoiding the need for welding for fixing during the construction of the transition layer. The connection of the longitudinal and transverse keels through the clamp mechanism simplifies the construction process, improves construction efficiency, and reduces safety hazards. At the same time, the components of the clamp mechanism can be flexibly reused, fully adapting to the requirements of rapid construction and green construction, and enhancing the competitiveness of enterprises in the construction of the ceiling transition layer.

[0014] In summary, this utility model achieves stability and safety in the ceiling structure connection by using a steel structure conversion mechanism and welding balls. The use of a connecting round pipe and welding balls increases the available space, thereby increasing the tensile strength and meeting load-bearing requirements. Simultaneously, it avoids pre-drilling bolt holes in the welding balls, ensuring their integrity and the quality of the ceiling. Furthermore, the use of clamp mechanisms to connect the longitudinal and transverse keels of the conversion layer eliminates the need for welding during construction. Connecting the longitudinal and transverse keels via clamp mechanisms simplifies the construction process, improves efficiency, and reduces safety hazards.

[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model includes a steel space frame, a transition layer keel layer 1 disposed below the steel space frame, and a steel structure transition mechanism disposed between the steel space frame and the transition layer keel layer 1.

[0029] The transition layer keel layer 1 includes multiple horizontal keels 2 and longitudinal keels 3, which are arranged horizontally. The horizontal keels 2 and longitudinal keels 3 are arranged vertically and are arranged in a cross shape. The connection between the horizontal keels 2 and longitudinal keels 3 is achieved by a clamping mechanism.

[0030] The clamping mechanism includes a U-shaped clamp 4 clamped on the longitudinal keel 3 and two L-shaped wing plates 5 symmetrically arranged on both sides of the U-shaped clamp 4 and connected to the transverse keel 2. The U-shaped clamp 4 and the two L-shaped wing plates 5 are integrally formed. The longitudinal keel 3 and the U-shaped clamp 4 are connected by a first connecting bolt 9, and the end of the transverse keel 2 and the L-shaped wing plates 5 are connected by a second connecting bolt 10.

[0031] The steel structure conversion mechanism includes a transition component assembly located below the welded ball 11 on the steel grid frame and a transition keel 12 vertically located at the bottom of the transition component assembly;

[0033] In actual use, the connection stability and safety of the ceiling structure are achieved by welding the steel structure conversion mechanism to the welding ball 11. The connection between the adapter round tube 13 and the welding ball 11 increases the reserved space, thereby increasing the tensile strength and meeting the load-bearing requirements. At the same time, it avoids reserving bolt holes on the welding ball 11, ensuring the integrity of the welding ball 11 and the quality of the ceiling.

[0034] In addition, the use of clamp mechanisms to connect the longitudinal and transverse keels of the transition layer avoids the need for welding for fixing during the construction of the transition layer.

At the same time, the components of the clamp mechanism can be flexibly reused, which can fully adapt to the requirements of rapid construction and green construction, and enhance the competitiveness of enterprises in the construction of the ceiling transition layer.

[0035] like Figure 1 As shown, the bottom of the transition keel 12 and the longitudinal keel 3 are connected by a fourth connecting bolt 19. The bottom of the transition keel 12 has a fourth mounting hole for installing the fourth connecting bolt 19. To ensure structural functionality, the number of the third mounting hole 18 and the fourth mounting hole is at least two. The second mounting hole 8 is an oblong hole. It should be noted that the height of the transition keel 12 in the hyperbolic transition layer ceiling is a specific height, and the length of each one is different.

[0036] In this embodiment, the opening of the U-shaped clamp 4 is away from the steel grid frame, the opening of the L-shaped wing plate 5 faces the steel grid frame, and the height of the L-shaped wing plate 5 is less than the height of the U-shaped clamp 4; the U-shaped clamp 4 has two symmetrically arranged first mounting holes 6 for the installation of the first connecting bolts 9, and the first mounting holes 6 are arranged at the bottom of the L-shaped wing plate 5; the L-shaped wing plate 5 has two symmetrically arranged first reinforcing ribs 7, and the first reinforcing ribs 7 are arranged at the bend of the L-shaped wing plate 5; the L-shaped wing plate 5 has a second mounting hole 8 for the installation of the second connecting bolts 10, and the second mounting hole 8 is arranged between the two first reinforcing ribs 7, and the second mounting hole 8 is arranged on the plate segment of the L-shaped wing plate 5 away from the U-shaped clamp 4.

[0037] In this embodiment, a plurality of second reinforcing ribs 15 are provided between the bottom of the adapter tube 13 and the adapter plate 14, and the plurality of second reinforcing ribs 15 are evenly distributed along the circumferential direction of the adapter tube 13; the top of the adapter tube 13 and the welding ball 11 are integrally formed; the connecting plate 16 is provided with a third mounting hole 18 for the installation of a third connecting bolt 17.
