Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically to a rapidly assembled irregular hyperboloid single-layer reticulated steel shell structure. Background Technology

[0002] With advancements in construction technology and increasing demands for architectural aesthetics, projects such as stadiums, large canopies, and railway station platforms composed of single-layer hyperboloid reticulated shell structures are on the rise. Construction methods generally employ high-altitude assembly and segmented hoisting, depending on the shell's shape and on-site conditions. However, existing irregularly shaped hyperboloid single-layer reticulated shell steel structures rely on bolts for fixation during use, which can lead to inefficiencies during later replacements and difficulties in splicing the shells during operation.

[0003] Referring to Chinese Patent No. CN219175477U, which discloses an irregularly shaped hyperboloid single-layer reticulated steel structure, the utility model features a first curved reticulated shell, a plug-in groove, a second curved reticulated shell, a connecting rod, and a plug-in block. These features facilitate the sliding insertion of the plug-in block into the plug-in groove during use, making assembly and installation easier and allowing for easy alignment and replacement after prolonged use. The inclusion of an inverted T-shaped threaded rod, a push nut, a hanging rod, and wing bolts allows for threaded connection of the inverted T-shaped threaded rod and wing bolts to the threaded holes during assembly, facilitating splicing and reinforcement and improving work efficiency.

[0004] However, when fixing the first and second curved mesh shells, the steel structure requires simultaneously tightening two inverted T-shaped threaded rods and two wing bolts, meaning there are four threaded fastening points. This makes the installation process cumbersome, time-consuming, and involves a large amount of work and difficulty, resulting in low installation efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a quick-assembly irregular hyperboloid single-layer reticulated steel shell structure, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution.

[0007] A rapidly assembled, irregularly shaped hyperboloid single-layer reticulated steel structure includes transverse steel structural rods, longitudinal steel structural rods, a first curved reticulated shell, a second curved reticulated shell, and a fastening structure. The longitudinal steel structural rods are fixedly welded between two transverse steel structural rods. The first curved reticulated shell is placed on top of one of the transverse steel structural rods, and the second curved reticulated shell is placed on top of the other transverse steel structural rod. Each of the first and second curved reticulated shells has a locking block fixed on one side and a locking groove on the other side. The locking blocks are matched and locked into the corresponding locking grooves. The fastening structure is used to fasten two adjacent first and second curved reticulated shells together to one of the transverse steel structural rods.

[0008] The quick positioning of two adjacent curved shell surfaces is achieved through the interlocking of the card blocks and slots, eliminating the need for complex alignment and reducing installation errors. At the same time, the combination of the pin and locking device simplifies the traditional four-point thread fastening to single-point fastening, significantly reducing installation steps and enabling rapid assembly of steel structures. This reduces the operational difficulty and time consumption during high-altitude operations or large-scale splicing, and greatly improves construction efficiency.

[0009] Furthermore, the card block is provided with a vertically penetrating pin hole, and the bottom wall of the card slot is provided with a vertically downward penetrating through hole. When the card block is matched and installed in the card slot, the pin hole is aligned with the through hole. The fastening structure includes a pin rod and a locking member. The pin rod is inserted into the pin hole and the through hole, and the locking member is provided on the transverse steel structure rod for fastening the first curved mesh shell and the second curved mesh shell to the transverse steel structure rod.

[0010] Furthermore, a retaining plate is fixed to the top of the pin, the diameter of which is larger than the inner diameter of the pin hole, and the retaining plate abuts against the top end face of the locking block.

[0011] Furthermore, the locking mechanism uses external hexagonal screws.

[0012] Furthermore, the transverse steel structure bar is provided with a insertion hole, and the end of the pin is matched and inserted into the insertion hole. The bottom of the transverse steel structure bar is provided with a bottom groove, and a through connecting hole is provided between the bottom groove and the insertion hole. The connecting hole extends horizontally, and the pin is provided with a locking screw hole. After the locking part is inserted into the through hole, it is threaded and tightened into the locking screw hole.

[0013] Furthermore, when the pin is installed in place, the retaining plate does not extend beyond the outside of the slot.

[0014] Furthermore, when the locking element is screwed into place, it does not extend beyond the bottom groove.

[0015] Furthermore, rubber pads are filled between the first curved mesh shell and the second curved mesh shell, between the first curved mesh shell and the transverse steel structure rod, and between the second curved mesh shell and the transverse steel structure rod.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows.

[0017] The quick positioning of two adjacent curved shell surfaces is achieved through the interlocking of the card blocks and slots, eliminating the need for complex alignment and reducing installation errors. At the same time, the combination of the pin and locking device simplifies the traditional four-point thread fastening to single-point fastening, significantly reducing installation steps and enabling rapid assembly of steel structures. This reduces the operational difficulty and time consumption during high-altitude operations or large-scale splicing, and greatly improves construction efficiency.

[0018] The retaining plate at the top of the pin does not extend beyond the slot after installation, and the external hexagonal screw locking parts do not extend beyond the bottom groove after tightening. This concealed design effectively prevents the pin and locking parts from being exposed to external impacts, wear, or corrosion, extending the service life of the components. At the same time, it ensures a clean and smooth appearance of the steel structure, avoids potential safety hazards to personnel or equipment caused by exposed components, and balances practicality and aesthetics.

[0019] The rubber pads between the first curved reticulated shell and the second curved reticulated shell, between the first curved reticulated shell and the transverse steel structure rod, and between the second curved reticulated shell and the transverse steel structure rod utilize elastic buffering properties to absorb vibration and impact when the structure is under stress, reduce rigid friction and stress concentration between components, improve the durability of the connection parts, fill the splicing gaps, block the intrusion of external moisture and dust, enhance the structural sealing, effectively cope with complex environments, and ensure the long-term stable operation of the steel structure.

[0027] In this embodiment of the invention, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" and "second" may explicitly or implicitly include one or more of that feature.

[0028] Please see Figures 1-4 This utility model provides a quick-assembly irregular hyperboloid single-layer reticulated steel structure, including a transverse steel structure rod 1, a longitudinal steel structure rod 2, a first curved reticulated shell 3, a second curved reticulated shell 4, and a fastening structure. The longitudinal steel structure rod 2 is fixedly welded between two transverse steel structure rods 1. The first curved reticulated shell 3 is placed on the top of one of the transverse steel structure rods 1, and the second curved reticulated shell 4 is placed on the top of the other transverse steel structure rod 1. Each of the first curved reticulated shell 3 and the second curved reticulated shell 4 has a locking block 5 fixed on one side and a locking groove 6 on the other side. The locking block 5 is matched and locked into the corresponding locking groove 6. The fastening structure is used to fasten two adjacent first curved reticulated shells 3 and second curved reticulated shells 4 together to one of the transverse steel structure rods 1.

[0029] Specifically, the card block 5 is provided with a vertically penetrating pin hole 51, and the bottom wall of the card groove 6 is provided with a vertically downward penetrating through hole 61. When the card block 5 is matched and installed in the card groove 6, the pin hole 51 is aligned with the through hole 61. The fastening structure includes a pin rod 7 and a locking member 8. The pin rod 7 is inserted into the pin hole 51 and the through hole 61. The locking member 8 is provided on the transverse steel structure rod 1 and is used to fasten the first curved mesh shell 3 and the second curved mesh shell 4 to the transverse steel structure rod 1.

[0030] The pin 7 is made of 45# steel after quenching and tempering, which has high strength and toughness. The pin 7 has a diameter of 24mm and a length of 200mm. A baffle 71 is fixed on the top. The baffle 71 has a diameter of 40mm and is larger than the inner diameter of the pin hole 51, so that the baffle 71 abuts against the top end face of the locking block 5.

[0031] Specifically, the transverse steel structure rod 1 is provided with a socket 11, and the end of the pin 7 is inserted into the socket 11. The bottom of the transverse steel structure rod 1 is provided with a bottom groove 12, and a through hole 13 is provided between the bottom groove 12 and the socket 11. The through hole 13 extends horizontally. The pin 7 is provided with a locking screw hole 72. After the locking part 8 is inserted into the through hole 13, it is screwed into the locking screw hole 72 with matching threads. The locking part 8 is a high-strength 8.8 grade external hexagonal screw. The locking screw hole 72 is M20 and is used to cooperate with the external hexagonal screw locking part 8 to provide sufficient fastening force.

[0032] The specific installation method for this steel structure is as follows:

[0033] First, weld the longitudinal steel structure rod 2 between the two transverse steel structure rods 1 to form a basic frame. Then, place the first curved mesh shell 3 and the second curved mesh shell 4 on the top of the two transverse steel structure rods 1 respectively, and align the locking block 5 with the locking slot 6 and insert it to complete the initial positioning.

[0034] Next, insert the pin 7 into the aligned pin hole 51 and through hole 61 from above until the lower end of the pin 7 is inserted into the insertion hole 11 on the transverse steel structure rod 1. At this time, the stop plate 71 abuts against the top of the locking block 5.

[0035] Then, place the external hexagonal screw in the bottom groove 12 and insert it into the connecting hole 13. Then, use a wrench to tighten the external hexagonal screw into the locking screw hole 72 to complete the assembly of the adjacent first curved mesh shell 3 and second curved mesh shell 4.

[0036] As can be seen, the quick positioning of adjacent curved mesh shells is achieved through the insertion and cooperation of the card block 5 and the card slot 6, without the need for a complicated alignment process, reducing installation errors. In addition, the alignment design of the pin hole 51 and the through hole 61 ensures that the pin 7 can be inserted vertically, providing guidance for subsequent fastening.

[0037] Traditional structures require multiple bolts for fastening, while this application uses a combination of a pin 7 and an external hexagonal screw to simultaneously fix adjacent first curved mesh shell 3 and second curved mesh shell 4. This reduces the number of fastening points, makes operation simple and convenient, and facilitates rapid assembly.

[0038] When the pin 7 is installed in place, the retaining plate 71 does not extend beyond the outside of the slot 6. When the locking part 8 is screwed in, it does not extend beyond the outside of the bottom groove 12. This ensures that the pin 7 and the locking part 8 are hidden and not exposed when installed in place, preventing the pin 7 and the locking part 8 from being subjected to external impact, wear or corrosion due to exposure. This improves the service life of the components and the reliability of the structure, while also ensuring the neatness and smoothness of the steel structure's appearance. It takes into account multiple effects such as practicality, durability and aesthetics.

[0039] Rubber pads (not shown in the figure) are filled between the first curved mesh shell 3 and the second curved mesh shell 4, between the first curved mesh shell 3 and the transverse steel structure rod 1, and between the second curved mesh shell 4 and the transverse steel structure rod 1. The rubber pads are soft and elastic, and play a buffering and protective role. They can effectively absorb the vibration and impact generated when the structure is under stress, reduce rigid friction and stress concentration between components, and improve the durability of the connection parts. In addition, the rubber pads can fill the splicing gaps, enhance the structural sealing, and further ensure the long-term stability of the steel structure.

[0040] The specific structure, model and coefficient indicators of the components used in this utility model are all its own technologies. As long as they can achieve the beneficial effects, they can be implemented. Therefore, they will not be described in detail.

[0041] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
