Description

Technical Field

[0001] This utility model relates to the field of spherical reticulated shell technology, and in particular to a spherical reticulated shell structure with a large space and a large span. Background Technology

[0002] In the field of modern architecture, the demand for large-space, long-span buildings is increasing, such as large stadiums, exhibition halls, and industrial plants. Spherical reticulated shell structures have become one of the ideal choices for realizing such large-space, long-span buildings due to their good spatial stress performance, high space utilization rate and unique architectural appearance.

[0003] Existing spherical reticulated shell structures typically employ hoisting and welding methods when installing the mortise frame. This method not only requires large hoisting equipment, increasing construction costs and difficulty, but also necessitates specialized welders, is time-consuming, and is significantly affected by weather and other environmental factors. Furthermore, welding quality is difficult to guarantee; welding defects can compromise the safety and stability of the entire structure. Some structures, while equipped with mating interfaces, still require hoisting during mortise frame installation. The mortise frame must then be rotated to align with the interface before bolting can be performed. This process is not only cumbersome and time-consuming, but also difficult to precisely control the position and angle of the mortise frame during hoisting and rotation, easily leading to alignment deviations and making bolting difficult or impossible, thus impacting construction progress and quality. Therefore, improvements are needed to address these issues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a large-space, large-span spherical reticulated shell structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A large-span spherical grid shell structure is provided, comprising a dome grid shell frame, with steel structure supports fixedly installed on the outer side of the dome grid shell frame. The steel structure supports include longitudinal keels, which are distributed around the surface of the dome grid shell frame. The bottom end of the longitudinal keels is fixedly connected to a tie frame. Support components are installed on the inner side of the dome grid shell frame, and the support components include mortises, which are symmetrically distributed at the center of the dome grid shell frame. Two sets of mortises are combined to form an X-shaped structure.

[0007] Preferably, the outer surface of the dome mesh frame is provided with insertion holes at positions corresponding to the keel, and the keel is inserted into the insertion holes. Multiple mounting holes are provided at equal intervals in the insertion holes, and lifting springs are provided in the mounting holes. Abutment blocks are fixedly connected to the top of the lifting springs. Fixing holes corresponding to the abutment blocks are provided at equal intervals on the rods of the keel located in the insertion holes.

[0008] Preferably, the warp keel is connected to the weft keel, and multiple sets of weft keels are provided, which are distributed from top to bottom on the surface of the warp keel.

[0009] Preferably, the bottom surface of the dome grid frame is provided with a support ring, and the combined cross section of the dome grid frame and the support ring is a C-shaped groove, with the mortise frame rotatably set in the C-shaped groove.

[0010] Preferably, the top surface of the dome grid frame is provided with an insertion interface corresponding to the shape of the end of the mortise frame, and multiple limiting blocks are provided at equal intervals in the C-shaped groove. The top surface of the frame body located in the C-shaped groove of the mortise frame is provided with a through hole. The mortise frame rotates and abuts against the front end of the limiting block. The dome grid frame and the supporting ring are fastened with bolts through the through hole.

[0011] Preferably, a cross steel bar is installed at the top of the mortise frame, and the periphery of the cross steel bar is fixedly welded to the top surface of the dome grid frame. A threaded hole is opened at the center of the mortise frame, and a long reinforcing bolt is connected inside the threaded hole. The long reinforcing bolt passes through the cross steel bar and is connected to the mortise frame.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model, through the cooperation of the lifting spring and the abutment block, and the fixing holes on the keel, facilitates the quick and stable installation on the dome grid frame, improving the convenience and efficiency of installation, and thus enabling the rapid construction of the steel structure support. Furthermore, through the cooperation of the C-shaped groove formed by the dome grid frame and the supporting ring, the limiting block, and the through holes and fastening bolts on the mortise frame, the rotation and positioning of the mortise frame are facilitated, improving the accuracy and efficiency of the mortise frame installation. This allows the mortise frame to be installed without complex hoisting and precise alignment. Finally, through the cooperation of the cross steel bar, the long rod reinforcing bolt and the mortise frame, the stability and support effect of the mortise frame are enhanced. Ultimately, this solves the problem that existing equipment requires hoisting and welding when installing the mortise frame, and the interface requires hoisting and rotation for alignment before bolt connection, resulting in inconvenient operation. This improves the installation efficiency and convenience of the entire spherical grid shell structure. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: See Figure 1-4 This utility model provides a large-span spherical grid shell structure, which includes a dome grid shell frame 1. A steel structure support is fixedly installed on the outside of the dome grid shell frame 1. The steel structure support includes a keel 2, which is distributed around the surface of the dome grid shell frame 1. A tie frame 3 is fixedly connected to the bottom end of the keel 2. A support component is installed on the inside of the dome grid shell frame 1. The support component includes a mortise frame 4, which is symmetrically distributed at the center of the dome grid shell frame 1. Two sets of mortise frames 4 are combined to form an X-shaped structure.

[0021] The X-shaped structure forms the basic framework of the spherical grid shell. The steel structure support enhances the stability of the dome grid shell frame 1. The keel 2 and the tie frame 3 provide support and restraint. The mortise frame 4 of the X-shaped structure provides internal support, improving the overall load-bearing capacity and stability of the structure, thereby enabling the structural support function for large spaces and large spans.

[0022] The outer surface of the dome-shaped mesh frame 1 has insertion holes at positions corresponding to the keel 2, and the keel 2 is inserted into the insertion holes. Multiple mounting holes are evenly spaced inside the insertion holes, and lifting springs 5 ​​are installed inside the mounting holes. Abutment blocks 6 are fixedly connected to the top of the lifting springs 5. Fixing holes corresponding to the abutment blocks 6 are evenly spaced on the rods of the keel 2 located inside the insertion holes. Through the cooperation of the lifting springs 5, abutment blocks 6 and fixing holes, the keel 2 can be quickly installed and fixed, improving installation efficiency and connection stability, thereby enabling the steel structure support to be quickly erected and securely connected.

[0023] The warp keel 2 is connected to the weft keel 7, and multiple sets of weft keels 7 are provided. The weft keels 7 are distributed from top to bottom on the surface of the warp keel 2. The warp keel 2 and the weft keel 7 are connected to each other to form a grid structure, which enhances the integrity and strength of the steel structure support, improves the deformation resistance of the structure, and thus can better withstand external loads and achieve a more reliable structural support function.

[0024] In this utility model, the bottom surface of the dome grid frame 1 is provided with a support ring 8. The combined cross section of the dome grid frame 1 and the support ring 8 is a C-shaped groove. The mortise frame 4 is rotatably set in the C-shaped groove. The support ring 8 and the C-shaped groove provide space for the mortise frame 4 to be installed and rotated, which facilitates the positioning and adjustment of the mortise frame 4, improves the flexibility and accuracy of the installation of the mortise frame 4, and makes it easier to complete the installation of the internal support structure.

[0025] The top surface of the dome-shaped grid frame 1 is provided with an insertion interface corresponding to the shape of the end of the mortise frame 4. Multiple limiting blocks 11 are provided at equal intervals in the C-shaped groove. The top surface of the frame body of the mortise frame 4 located in the C-shaped groove is provided with a through hole. The mortise frame 4 rotates and abuts against the front end of the limiting block 11. The dome-shaped grid frame 1 and the supporting ring 8 are connected by fastening bolts 9 through the through hole. The cooperation of the insertion interface, the limiting block 11 and the fastening bolts 9 enables the mortise frame 4 to be accurately installed and fixed in a suitable position, which improves the stability and firmness of the installation of the mortise frame 4, and thus ensures that the internal support structure can effectively play its supporting role.

[0026] A cross steel bar 10 is installed at the top of the mortise frame 4. The cross steel bar 10 is fixedly welded to the top surface of the dome grid shell frame 1. A threaded hole is opened at the center of the mortise frame 4, and a long rod reinforcing bolt 12 is connected inside the threaded hole. The long rod reinforcing bolt 12 passes through the cross steel bar 10 and connects to the mortise frame 4. The cross steel bar 10 and the long rod reinforcing bolt 12 further enhance the connection strength and stability between the mortise frame 4 and the dome grid shell frame 1, improve the reliability of the entire support structure, and thus better ensure the safety and stability of the large-space, large-span spherical grid shell structure.

[0027] Working principle: In use of this utility model, the keel 2 is first installed around the outer surface of the dome grid frame 1. The lifting spring 5 inside the insertion hole of the dome grid frame 1 drives the abutment block 6 to spring into the fixing hole of the keel 2, realizing a quick and stable connection between the two. Then, multiple sets of weft keels 7 are connected from top to bottom, and they interweave to form a grid-like steel structure support. The binding frame 3 connected to the bottom end of the keel 2 reinforces the bottom and provides an external support frame for the whole. At the same time, the mortise frame 4 is rotatably installed in the C-shaped groove formed by the support ring 8 on the bottom surface of the dome grid frame 1 and the dome grid frame 1. The position of the mortise frame 4 is determined by the limiting block 11 in the C-shaped groove and the fastening bolt 9. The mortise frame 4 is symmetrically distributed in an X shape at the center position. The cross steel bar 10 installed at the top of the mortise frame 1 is fixedly welded to the top surface of the dome grid shell frame 1. The threaded hole at the center position is screwed into the long rod reinforcing bolt 12 to enhance the connection strength. When the structure is subjected to external loads, the external steel structure support will transfer the load to the dome grid shell frame 1. The internal mortise frame 4 support system works in concert to share and disperse the load, ensuring the stable bearing of the large-span spherical grid shell structure and meeting the needs of building space use. The device is now in use.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
