Abstract
Description
Technical Field
[0001] This utility model relates to the field of building steel structure technology, and in particular to an integrated prefabricated green building steel structure. Background Technology
[0002] When constructing prefabricated steel structures for green buildings, a common approach is to use prefabricated steel components for rapid on-site assembly. Through standardized design, factory production, and modular construction, this method achieves high efficiency, environmental friendliness, and energy conservation in the construction process. This structural form significantly shortens the construction cycle, reduces noise and dust pollution during construction, and reduces construction waste due to the recyclability of its materials, aligning with the concept of sustainable development. Furthermore, prefabricated green building steel structures offer excellent seismic performance and high space utilization, providing residents with a safe and comfortable living environment. Therefore, using this structural form brings multiple benefits, including improved construction efficiency, enhanced environmental protection, and improved building safety and flexibility.
[0003] The prefabricated green building steel structure encompasses design, factory prefabrication, transportation, on-site assembly, and acceptance. Through precise design, it ensures structural rationality and green performance. Components are prefabricated with high precision in the factory, transported professionally to the construction site for efficient assembly, and finally, strict acceptance ensures project quality and environmental standards, achieving green and industrialized construction of buildings.
[0004] Existing technologies for prefabricated green building steel structures have several shortcomings in practical applications. The limitations are particularly pronounced in the steel structure's positioning and splicing stages. Firstly, some splicing methods are difficult to position precisely, leading to positional deviations during installation. This not only reduces construction efficiency but also affects the overall stability and safety of the building. Secondly, due to the lack of an effective positioning mechanism, the spliced structure is prone to relative displacement between components when subjected to external loads, resulting in structural deformation and significantly weakening the building's load-bearing capacity. Furthermore, traditional splicing techniques require extensive on-site welding or bolt tightening, which generates noise and exhaust pollution, contradicting the environmental principles of green building. The large amount of on-site work also prolongs the construction period and increases costs. Therefore, this paper proposes a prefabricated green building steel structure to address these issues.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0033] Reference Figures 1 to 2 This utility model provides an embodiment of an integrated prefabricated green building steel structure, including a base 1, which is the basic support component of the entire green building steel structure, and evenly transfers the weight of the column 2 to the foundation, providing a stable support foundation for the entire building. The top of the base 1 is fixedly connected to the column 2, which is the main vertical support component of the entire building steel structure, bearing the gravity load of the upper structure as well as horizontal loads such as wind load and seismic load, and transferring them to the base 1. At the same time, the column 2 also provides support and connection foundation for the installation of limiting mechanism and splicing mechanism. The external of the column 2 is provided with a limiting mechanism, and the external side of the column 2 is provided with a splicing mechanism.
[0034] The limiting mechanism includes a mounting block 3, which is the main component of the limiting mechanism and provides the mounting base for the entire limiting mechanism. It cooperates with the column 2 through the through groove 4 and the groove 5 inside to connect the column 2. The through groove 4 is opened in the internal space area of the mounting block 3 to provide a sliding guide channel for the column 2. When the building steel structure deforms or needs to be adjusted under different working conditions, the column 2 can slide in the through groove 4 to achieve fine adjustment of the position of the column 2 and ensure the stability and safety of the building steel structure. The grooves 5 are opened on the left and right sides inside the mounting block 3, which cooperate with the slider 6 to limit the range of movement of the column 2 in the horizontal direction. When the column 2 is subjected to lateral force, the slider 6 slides in the groove 5, thereby playing the role of limiting and stabilizing the column 2.
[0035] Slider 6 is fixedly connected to the left and right sides of the outside of column 2. It is firmly fixed to the two sides of column 2 by welding. It can slide smoothly in groove 5, effectively guide the installation of column 2 and limit the lateral displacement of column 2. Through holes 7 are opened on the left and right sides of the outside of column 2. The through holes 7 are symmetrically opened on the two sides of column 2 and aligned with the corresponding positions on the mounting block 3. An adjustment component is installed in the through hole 7. The adjustment component can realize the tight connection or flexible adjustment between column 2 and mounting block 3. The adjustment component is fixedly connected inside the through hole 7. It is the core component of the adjustment component. By rotating bolt 8, its position in the through hole 7 can be adjusted, thereby changing the relative position between mounting block 3 and column 2, and realizing the fine adjustment of the verticality and horizontality of column 2.
[0036] The adjustment component is fitted with retraction springs 9 on the left and right sides. During the adjustment process, when the bolt 8 moves under the action of external force, the retraction springs 9 will generate elastic deformation, store energy and provide a certain restoring force. When the external force disappears, the restoring force of the retraction springs 9 can keep the bolt 8 in the new position, thereby achieving stable adjustment of the position of the bolt 8. The external sliding connection of the column 2 is in the internal space area of the through groove 4. The external left and right sides of the slider 6 are slidably connected to the internal left and right sides of the groove 5. The external left and right sides of the through hole 7 are opened on the external left and right sides of the mounting block 3.
[0037] The splicing mechanism includes a support plate 10, which is firmly fixed to the outside of the mounting block 3 by welding. It provides a stable support platform for the installation of the crossbeam 13 and can transfer the load borne by the crossbeam 13 to the mounting block 3, thereby distributing it throughout the entire building structure. A groove 11 is provided on one side of the inside of the support plate 10, providing a sliding channel for the slider 12. The slider 12 can slide along the direction of the groove 11 on the support plate 10, thereby realizing the subsequent splicing operation. The slider 12 is slidably connected to the inside of the groove 11. It slides in the groove 11 and, through its connection with the crossbeam 13, transmits the movement of the slider 12 to the crossbeam 13, thereby realizing the adjustment of the position of the crossbeam 13 and completing the splicing operation of the splicing mechanism. The outside of the support plate 10 is fixedly connected to the outside of the mounting block 3.
[0038] Reference Figures 2 to 3The adjustment assembly includes bolt 8, which is externally fixed to the inside of the through hole 7. The externally fixed to the outside of the contraction spring 9 is the outside of bolt 8. Bolt 8 is externally fixed to the inside of the column 2. Bolt 8 is externally fixed to the inside of the mounting block 3. A crossbeam 13 is fixedly connected to one side of the slider 12. It is a key load-bearing component in the splicing mechanism. The crossbeam 13 is mainly used to bear various forces during the splicing process of the building steel structure and to distribute these forces evenly to the mounting block 3 and the support plate 10. At the same time, through cooperation with the expansion tube 14, it realizes the splicing and fixing of the building steel structure.
[0039] An expansion tube 14 is fixedly connected to one side of the inner side of the crossbeam 13. During the splicing process, the expansion tube 14 achieves the function of tightening and fixing the building steel structure through the cooperation of the countersunk bolt 15 and the expansion tube head 19 inside. When the countersunk bolt 15 is tightened, the expansion tube 14 will expand outward, thereby making the connection between the building steel structures tighter and stronger. The outer side of the crossbeam 13 is fixedly connected to the outer side of the mounting block 3, and the outer left and right sides of the crossbeam 13 are fixedly connected to the outer left and right sides of the support plate 10.
[0040] The internal thread of the expansion tube 14 is connected to a countersunk bolt 15. The countersunk bolt 15, through its threaded connection with the expansion tube 14, tightly fixes the building steel structure together. When the countersunk bolt 15 is tightened, it generates an axial force on the expansion tube 14, causing the expansion tube 14 to expand outward, thereby achieving the splicing and fixing of the building steel structure. The external thread of the countersunk bolt 15 is connected to a hexagonal nut 16, which works in conjunction with the countersunk bolt 15. By rotating the hexagonal nut 16, the countersunk bolt 15 can be tightened and loosened, thereby controlling the degree of expansion of the expansion tube 14, and thus achieving the splicing and fixing of the building steel structure.
[0041] Reference Figures 3 to 4 A flat washer 17 is fixedly connected to the outer side of the hexagonal nut 16. The flat washer 17 is located between the hexagonal nut 16 and the expansion tube 14, and plays a role in buffering and protection. When the countersunk bolt 15 is tightened, the flat washer 17 can distribute the pressure and prevent the hexagonal nut 16 from pressing directly on the expansion tube 14, thereby reducing damage to the surface of the expansion tube 14 and ensuring the tightness of the connection. The outer side of the flat washer 17 is fixedly connected to the outer side of the expansion tube 14.
[0042] An expansion head 18 is fixedly connected to the outer side of the countersunk bolt 15. When the countersunk bolt 15 is tightened, the expansion head 18 will rotate inside the expansion tube head 19 and move outward, thereby causing the expansion tube 14 to expand outward. This movement of the expansion head 18 can convert the axial force of the countersunk bolt 15 into the radial expansion force of the expansion tube 14, realizing the splicing and fixing of the building steel structure. An expansion tube head 19 is fixedly connected to the outer side of the expansion tube 14. During the splicing process, the expansion tube head 19 provides the movement space and support for the expansion head 18. When the expansion head 18 rotates inside the expansion tube head 19 and moves outward, the expansion tube head 19 will guide and restrict the movement of the expansion head 18, so that it can move in a predetermined direction and trajectory, thereby realizing the accurate tightening of the expansion tube 14 and ensuring the splicing quality of the building steel structure.
[0043] The external rotatable connection of the expansion head 18 is connected to the inside of the expansion tube head 19. A triangular plate 20 is fixedly connected to the external side of the support plate 10. Through the connection with the crossbeam 13 and the support plate 10, the triangular plate 20 can form a stable triangular structure. By utilizing the stability principle of triangles, the stability of the splicing mechanism when subjected to external forces is improved. The external side of the triangular plate 20 is fixedly connected to the outside of the crossbeam 13.
[0044] Working principle: When the steel structure of the building needs to be adjusted or deformed due to different working conditions, the column 2 can slide in the through groove 4 of the mounting block 3 to achieve fine-tuning of its position; at the same time, the sliders 6 on both sides of the column 2 slide in the grooves 5 of the mounting block 3 to limit the horizontal movement range of the column 2 in order to cope with lateral forces. By rotating the bolt 8 of the adjusting component in the through hole 7, its position in the through hole 7 is adjusted, changing the relative position of the mounting block 3 and the column 2, thereby achieving fine-tuning of the verticality and horizontality of the column 2. During the adjustment process, when the bolt 8 is moved by external force, the spring 9 generates elastic deformation to store energy and provide restoring force. After the external force disappears, the spring restoring force keeps the bolt 8 in the new position.
[0045] The support plate 10 is fixed to the outside of the mounting block 3 by welding, providing a support platform for the installation of the crossbeam 13. The slider 12 slides in the groove 11 on one side of the support plate 10. Its movement is transmitted to the crossbeam 13 through the connection with the crossbeam 13, realizing the adjustment of the position of the crossbeam 13. The internal thread of the expansion tube 14 is connected to the countersunk bolt 15, and the external thread of the countersunk bolt 15 is connected to the hexagonal nut 16. Rotating the hexagonal nut 16 can control the tightening and loosening of the countersunk bolt 15. When the countersunk bolt 15 is tightened, the expansion head 18 on the countersunk bolt 15 rotates and moves outward in the expansion tube head 19 outside the expansion tube 14, causing the expansion tube 14 to expand outward, realizing the expansion and fixation of the building steel structure. The flat washer 17 between the hexagonal nut 16 and the expansion tube 14 plays a buffering and protective role.
[0046] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
