[0011] Compared with the prior art, the beneficial effects of this utility model are: 1.

Each module is precisely aligned using pre-set standardized spacing positioning holes. The structure is then reinforced by hierarchical connection locking. Steel beams are inserted into No. 1 fixed bases, and inserts from mounting frames and connecting frames are inserted into No. 2 fixed bases. The tightness of the fit between the inserts and No. 2 fixed bases is adjusted, and the threads are self-locking to prevent loosening. This ensures the assembly accuracy of the factory frame and the stability of the node connections. Furthermore, the modular prefabrication and detachable connections improve construction efficiency and reduce later maintenance costs.

[0012] 2. This prefabricated steel structure factory frame utilizes locking brackets to limit the engagement of X-shaped cross supports, combining the mechanical reinforcement principle of distributing loads to both sides through the X-shaped structure. The locking connections enable rapid assembly of the supports, and the locking components, along with the matching engagement with the steel beams and mounting frames, form a two-way mechanical constraint, facilitating subsequent disassembly and adjustment. Finally, the locking brackets and mounting frames are pre-positioned, and the adjustable brackets, with their adjustable position and shape, accommodate alignment deviations between the mounting frames and surrounding components. This improves the construction error tolerance without disassembly and reassembly, ultimately achieving a synergistic effect from support and fixation to adjustment, ensuring the stability of the connections around the No. 1 fixed base, ease of construction, and precision of subsequent connections.

[0015] 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.

[0016] Example 1: Please refer to Figures 1-5. A prefabricated steel structure factory frame includes steel columns 1, connecting columns 4, connecting seats 7, mounting brackets 16, and locking components 15. A base 2 is provided on the outer surface of the steel column 1. A first seat 3 is fixedly installed on the outer surface of the steel column 1 away from the base 2. A second seat 5 is fixedly installed on the outer surface of the connecting column 4. A third seat 6 is fixedly installed on the outer surface of the connecting column 4 away from the second seat 5. An extension seat 9 is fixedly installed on the outer surface of the third seat 6. Several spacings are provided on the outer surfaces of the first seat 3, second seat 5, third seat 6, and connecting seats 7. Positioning hole 8, connecting seat 7 has a first fixing seat 10 and a second fixing seat 11 fixedly installed on its outer surface. A steel beam 12 is inserted and connected to the outer surface of the first fixing seat 10. A connecting frame 17 is slidably connected to the outer surface of the mounting frame 16. A screw 19 is fixedly installed on the outer surface of the mounting frame 16. A screw seat 20 is threadedly connected to the outer surface of the screw 19. The screw seat 20 is rotatably connected to the connecting frame 17. Insert blocks 18 are fixedly installed on the outer surfaces of both the mounting frame 16 and the connecting frame 17. Insert blocks 18 are inserted and fixed to the second fixing seat 11.

[0017] Specifically, the frame is first divided into independent modules: steel column 1 with base 2 and No. 1 base 3; connecting column 4 with No. 2 base 5, No. 3 base 6 and extension base 9; connecting seat 7 with No. 1 fixed seat 10 and No. 2 fixed seat 11; and mounting bracket 16 and connecting bracket 17 with insert block 18, screw 19 and screw seat 20. Each module is precisely aligned through preset standardized spacing positioning holes 8 to avoid manual measurement errors. Then, the structure is reinforced by hierarchical connection and locking. Steel beam 12 is inserted into No. 1 fixed seat 1. 0. The insertion blocks 18 of the mounting bracket 16 and the connecting bracket 17 are inserted into the second fixed seat 11 to complete the initial assembly. Then, the screw seat 20 is rotated, and the connecting bracket 17 is pushed to slide along the mounting bracket 16 by the thread transmission between the screw 19 and the screw seat 20. The tightness of the fit between the insertion block 18 and the second fixed seat 11 is adjusted and the looseness is prevented by the thread self-locking. This achieves the effect of ensuring the assembly accuracy of the factory frame and the stability of the node connection. Furthermore, the modular prefabrication and detachable connection improve the construction efficiency and reduce the later maintenance cost.

[0018] In this embodiment: a linear guide rail is provided on the outer surface of the mounting bracket 16, and a slider adapted to the linear guide rail is fixedly installed on the inner surface of the connecting bracket 17. The slider is slidably connected to the linear guide rail. The screw seat 20 and the connecting bracket 17 are rotatably connected by a bearing. The inner ring of the bearing is fixedly connected to the screw seat 20, and the outer ring of the bearing is fixedly connected to the connecting bracket 17.

[0019] Specifically, firstly, relying on the precise fit between the linear guide rail of the mounting bracket 16 and the slider of the connecting bracket 17, the slider is constrained to slide only along the axis by the preset linear trajectory of the guide rail, avoiding lateral offset or tilting of the connecting bracket 17, and ensuring that its insert 18 can be accurately aligned with the second fixed seat 11; then, the screw seat 20 and the connecting bracket 17 are connected by a bearing. By using the structure of fixing the screw seat 20 with the inner ring of the bearing and fixing the connecting bracket 17 with the outer ring, the sliding friction when the screw seat 20 rotates is converted into rolling friction to reduce the adjustment resistance. At the same time, the relative coaxiality of the two is maintained to prevent the screw seat 20 from radially shaking. Finally, the sliding trajectory of the connecting bracket 17 is accurately guaranteed. The resistance reduction and positioning of the bearing ensure that the rotation of the screw seat 20 can be efficiently converted into the linear movement of the connecting bracket 17. This makes the connection and adjustment of the insert 18 and the second fixed seat 11 more effortless and precise, reduces the frictional wear of the components, and improves the structural adjustment stability and service life.

[0020] In the embodiment: the outer surface of the second fixing base 11 is provided with a slot that matches the plug 18. The plug 18 has a rectangular cross-section, and after the plug 18 is inserted into the slot, it is further fixed to the second fixing base 11 by bolts.

[0021] Specifically, by utilizing the shape constraints of the rectangular insert 18 and the matching slot on the second fixing seat 11, the rectangular structure has no circumferential rotational freedom, and the inner wall of the slot can restrict the lateral sway of the insert 18, quickly completing the initial precise alignment and pre-fixation of the insert 18 and the second fixing seat 11, avoiding the offset or rotation of the insert 18 during subsequent bolt installation, and ensuring precise alignment of the bolt holes; then, by passing the bolt through the preset holes of the insert 18 and the second fixing seat 11, the axial pressure generated by the thread transmission when tightening the bolt tightly presses the insert 18 into the slot to eliminate residual gaps. At the same time, the self-locking characteristics of the bolt thread resist the loosening tendency caused by vibration and load. In the end, the shape adaptation ensures the connection positioning accuracy, the bolt tightening strengthens the node stability, and the detachable characteristics of the bolt also take into account the convenience of later maintenance.

[0022] Working principle: A base 2 is provided on the outer surface of the steel column 1. A first seat 3 is fixedly installed on the outer surface of the steel column 1 away from the base 2. A second seat 5 is fixedly installed on the outer surface of the connecting column 4. At the same time, a third seat 6 is fixedly installed on the outer surface of the connecting column 4 away from the second seat 5. An extension seat 9 is fixedly installed on the outer surface of the third seat 6. Several spacing positioning holes 8 are opened on the outer surfaces of the first seat 3, the second seat 5, the third seat 6, and the connecting seat 7. In addition, a first fixing seat 10 and a second fixing seat 10 are fixedly installed on the outer surface of the connecting seat 7. The outer surface of the fixed base 11 and the first fixed base 10 is connected to a steel beam 12. The outer surface of the mounting frame 16 is slidably connected to a connecting frame 17, and the outer surface of the mounting frame 16 is fixedly mounted with a screw 19. The outer surface of the screw 19 is threadedly connected to a screw seat 20, which is rotatably connected to the connecting frame 17. The outer surfaces of both the mounting frame 16 and the connecting frame 17 are fixedly mounted with insert blocks 18, which are inserted and fixed to the second fixed base 11. The frame is first disassembled into a steel column 1 with a base 2 and a first base 3, and a steel column 1 with a second base 3. The independent modules of the mounting bracket 16 and the connecting bracket 17, which include the connecting column 4 of the base 5, the connecting column 6 of the third base, and the extension base 9; the connecting bracket 7 with the first fixed base 10 and the second fixed base 11; and the mounting bracket 16 with the insert block 18, the screw 19, and the screw seat 20, are all precisely aligned through the preset standardized spacing positioning holes 8 to avoid manual measurement errors. The structure is then reinforced by a graded connection and locking mechanism. The steel beam 12 is inserted into the first fixed base 10, and the insert block 18 of the mounting bracket 16 and the connecting bracket 17 is inserted into the second fixed base 11 to complete the initial assembly. Then, rotate the screw seat 20, and use the thread transmission between the screw 19 and the screw seat 20 to push the connecting frame 17 to slide along the mounting frame 16. Adjust the tightness of the fit between the plug block 18 and the second fixing seat 11, and prevent loosening through thread self-locking. Compared with related technologies, the prefabricated steel structure factory frame provided by this utility model has the following beneficial effects: it achieves the effect of ensuring the assembly accuracy and node connection stability of the factory frame, and improves construction efficiency and reduces later maintenance costs due to modular prefabrication and detachable connection.

[0023] Example 2: Please refer to Figures 1-5. A card holder 14 is fixedly installed on the outer surface of the first fixed base 10. A support member 13 is engaged with the outer surface of the card holder 14. The support member 13 is arranged in an X-shaped interlocking configuration. Locking members 15 are engaged with the outer surfaces of the steel beam 12 and the mounting frame 16. An adjusting frame 21 is engaged with the outer surface of the mounting frame 16.

[0024] Specifically, by using the locking seat 14 to engage and limit the X-shaped cross support 13, combined with the mechanical reinforcement principle of distributing the load to both sides by the X-shaped structure, the support strength and anti-lateral displacement capability of the first fixed seat 10 are strengthened, preventing it from tilting and deforming due to load or external forces. The locking connection also enables the rapid assembly of the support 13. Furthermore, the locking part 15, steel beam 12, and mounting frame 16 are matched and locked to form a two-way mechanical constraint, which can fix the two without additional bolts or welding, preventing vibration displacement, and facilitating subsequent disassembly and adjustment. Finally, the adjustment frame 21 is pre-positioned by engaging with the mounting frame 16. Combined with the adjustable position or shape of the adjustment frame 21, it adapts to the alignment deviation between the mounting frame 16 and surrounding components, improving the construction error tolerance without disassembly and reassembly. Moreover, the locking structure ensures stability and no deviation after adjustment, thus achieving the effect of synergistically ensuring the stability of the surrounding connections of the first fixed seat 10, construction convenience, and subsequent connection accuracy from the support, fixing, and adjustment levels.

[0025] In the embodiment: both the steel column 1 and the steel beam 12 are made of high-strength alloy steel, and the outer surface of the steel column 1 and the steel beam is also coated with an anti-corrosion coating. The adjusting frame 21 includes an inner rod and an outer rod that are nested together. The outer surface of the outer rod is threaded with a locking bolt for locking the extension and retraction position of the inner rod. The two ends of the adjusting frame 21 are locked and fixed to the mounting frame 16 by clamps. The outer surface of the locking member 15 is provided with a reinforcing bolt. The locking member 15 is fixedly connected to the steel beam 12 and the mounting frame 16 by the reinforcing bolt, and the locking member 15 is set at an angle of 90 degrees to the steel beam 12 and the mounting frame 16.

[0026] Specifically, steel column 1 and steel beam 12 are made of high-strength alloy steel. Through alloy composition optimization and process treatment, they are endowed with high tensile strength, yield strength and toughness. Relying on the mechanical properties of the material, they directly bear vertical and lateral loads, which not only improves the load-bearing and deformation resistance and ensures the long-term stability of the structure, but also reduces the cross-sectional size of the components to reduce weight and save materials. At the same time, steel column 1 and steel beam 12 are coated with anti-corrosion coating. The dense isolation layer blocks the contact of corrosive media. Some coatings can also achieve cathodic protection, effectively inhibiting rust, extending service life and reducing later maintenance costs. The adjusting frame 21 forms a telescopic structure by connecting the inner rod and the outer rod. The length can be adjusted by changing the insertion depth of the inner rod to accommodate installation deviations. The outer rod's set bolt tightens the inner rod to lock its position through threaded transmission. The clamps at both ends quickly engage and fix the frame 16 through clamping force, balancing adjustment flexibility and connection stability, improving construction error tolerance and facilitating later adjustments. The locking component 15 further relies on the threaded connection of the reinforcing bolt to form axial pressure, strengthening the connection strength with the steel beam 12 and the mounting frame 16 to prevent loosening. At the same time, it is set at a 90-degree angle to the component, making the force direction perpendicular to the main load direction of the component, optimizing the force transmission path to distribute the load, avoid stress concentration, ensure reliable connection between the steel beam 12 and the mounting frame 16, and facilitate later inspection and re-tightening.

[0027] In the embodiment: the spacing between the holes of the positioning holes 8 is 50mm to 100mm, and the positioning holes 8 are used to cooperate with the positioning pins. The outer surface of the card seat 14 is provided with a fixing bolt. The card seat 14 and the support member 13 are fixedly connected to the card seat 14 through the fixing bolt. The first fixing seat 10 and the second fixing seat 11 are set at an angle of 90 degrees.

[0028] Specifically, a standardized hole spacing of 50mm to 100mm is preset in the positioning holes 8 to provide a unified positioning benchmark for the steel column 1 (base 3), the connecting column 4 (base 5 or 6), and the connecting base 7. The tight fit between the positioning pins and the hole walls restricts the lateral displacement of the components, achieving rapid and precise alignment of the components to improve construction efficiency. Furthermore, the adaptable hole spacing range and detachable positioning pins ensure both applicability and ease of future maintenance. The pre-positioning of the card seat 14 and the support member 13, along with the axial pressure generated by the threaded drive after the fixing bolt passes through the preset holes, enhances the friction between them and restricts the sliding of the support member 13, further strengthening the connection. The connection strength is enhanced to prevent the support component 13 from slipping under load. At the same time, the standardized fixing bolts reduce the difficulty of construction and facilitate disassembly and maintenance. Finally, the 90-degree angle between the first fixing seat 10 and the second fixing seat 11 forms a vertical force-bearing plane, which respectively bears the vertical load of the steel beam 12 and the lateral and horizontal loads of the mounting frame 16 to avoid stress superposition. At the same time, the spatial arrangement of the steel beam 12 and the mounting frame 16 is optimized to reduce mutual interference. This not only improves the deformation resistance of the connecting seat 7, but also facilitates simultaneous assembly during construction and reserves space for the installation of subsequent components. Overall, from positioning and reinforcement to the stress level, the structure is guaranteed to be stable and construction is convenient.

[0029] Working principle: A retaining bracket 14 is fixedly installed on the outer surface of the first fixed base 10. A support member 13 is engaged with the outer surface of the retaining bracket 14. The support member 13 is arranged in an X-shaped cross engagement. In addition, locking members 15 are engaged with the outer surfaces of the steel beam 12 and the mounting frame 16. An adjusting bracket 21 is engaged with the outer surface of the mounting frame 16. The retaining bracket 14 limits the engagement of the X-shaped cross support member 13. The mechanical reinforcement principle of the shape structure that distributes the load to both sides not only strengthens the support strength and anti-lateral displacement capacity of the No. 1 fixed seat 10, preventing it from tilting and deforming due to load or external forces, but also enables the rapid assembly of the support component 13 through the snap-fit ​​connection; then, the locking component 15 and the steel beam 12 and the mounting frame 16 are matched and snap-fit ​​to form a two-way mechanical constraint, which can fix the two without additional bolts or welding, prevent vibration displacement, and facilitate subsequent disassembly and adjustment; finally, the adjustment frame 21 and the mounting frame 16 are snap-fit ​​for pre-positioning. Combined with the adjustable position or shape of the adjustment frame 21, it can adapt to the alignment deviation between the mounting frame 16 and the surrounding components, improving the construction error tolerance without disassembly and reassembly. Moreover, the snap-fit ​​structure ensures stability and no displacement after adjustment. Compared with related technologies, the modular steel structure factory frame provided by this utility model has the following beneficial effects: thus achieving the effect of synergistically ensuring the stability of the surrounding connections of the No. 1 fixed seat 10, the convenience of construction, and the accuracy of subsequent connections from the support, fixing and adjustment levels.
