Description

Technical Field

[0001] This utility model relates to the field of building steel structure connection technology, specifically a connecting component for building steel structures. Background Technology

[0002] Steel is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation, making it particularly suitable for constructing large-span, super-high, and super-heavy buildings. It also exhibits good homogeneity and isotropy, making it an ideal elastic material that best conforms to the basic assumptions of general engineering mechanics. Furthermore, it possesses good plasticity and toughness, allowing for significant deformation and excellent resistance to dynamic loads. Construction periods are short, and its high degree of industrialization enables highly mechanized and specialized production. Research should focus on high-strength steel to significantly improve its yield strength. In addition, new types of steel profiles, such as H-beams (also known as wide-flange steel) and T-beams, as well as profiled steel sheets, need to be rolled to meet the needs of large-span structures and super-high-rise buildings. Therefore, it is necessary to study the connectors required for building steel structures.

[0003] The current connection and fixing of steel pipes in steel structures suffers from insufficient stability, which makes the device prone to breakage during actual use. This negatively impacts the connection and fixing effect between steel pipes. Currently, the stability of the connection and fixing of steel pipes in steel structures is poor, making the device prone to breakage during use and affecting the actual effect of the connection and fixing. To address this issue, we propose a connector for building steel structures. Utility Model Content

[0004] The purpose of this utility model is to provide a connector for building steel structures to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a connector for a building steel structure, comprising a first steel pipe, a connecting component sleeved at the middle position of the first steel pipe, the connecting component comprising a first connecting frame, the first connecting frame sleeved on the outside of the first steel pipe, and mounting frames fixedly connected to both the front and rear ends of the first steel pipe, and mounting plates fixedly connected to the upper end of the mounting frames, second connecting frames fixedly connected to both the upper and lower ends of the first connecting frame, reinforcing plates fixedly connected to both the front and rear ends of the second connecting frame, second steel pipes inserted into both the upper and lower ends of the second connecting frame, fixing frames fixedly connected to both the left and right ends of the first connecting frame, and a mounting block engaging at the other end of the fixing frame, a third connecting frame fixedly connected to the other end of the mounting block, and a fixing bolt inserted into the front end of the fixing frame.

[0006] Preferably, the upper end of the first connecting frame is provided with a through groove, and two mounting plates are fixedly connected to the upper end of the mounting frame at the through groove position.

[0007] Preferably, two sets of bolts are inserted into the mounting plate, the ends of the bolts are fitted with nuts, and two washers are fitted onto the bolts. One washer has both ends abutting against the bolt and the mounting plate, and the other washer abuts against the nut and the mounting plate. The two bolts are inserted into the mounting plate in opposite directions.

[0008] Preferably, the front end of the second connecting frame is provided with a through groove, and both ends of the reinforcing plate are fixedly connected to the second connecting frame and the first connecting frame. The reinforcing plate is arranged in a triangular structure.

[0009] Preferably, a bolt is inserted into the second connecting frame, and a nut is fitted onto the bolt. The bolt passes through the second steel pipe, and a slot that mates with the bolt is provided on the second steel pipe. The second connecting frame is provided with slots that mate with the bolt evenly.

[0010] Preferably, the mounting block is configured in a T-shape, and the fixing frame has a T-shaped slot that mates with the mounting block. The third connecting frame is embedded in the fixing frame through the mounting block.

[0011] Preferably, the outer surface of the fixing bolt is uniformly provided with threaded grooves, and both the fixing frame and the mounting block are provided with threaded slots that mate with the fixing bolt. A ring is fixedly connected to the front end of the fixing bolt.

[0012] This utility model provides a connector for building steel structures, which has the following advantages:

[0013] By connecting the mounting frame and mounting plate to the first connecting frame, and using bolts and nuts, the first steel pipe can be inserted into the first connecting frame, the bolts can be inserted into the mounting plate, and the nuts can be fitted onto the bolts to fix the mounting plate and install the mounting frame. The installation of the mounting frame makes the first connecting frame more secure when it is fitted onto the outside of the first steel pipe, preventing the first steel pipe from breaking during use. At the same time, by evenly opening slots on the second connecting frame to mate with the bolts, the insertion position of the bolts can be adjusted according to the different lengths of the second steel pipes, and then fixed with nuts, which increases the practicality of this device in use.

[0014] The third connecting frame is movably engaged with the fixed frame via the mounting block and locked by the fixing bolt. When there are few steel pipes to be connected, the fixing bolt can be rotated to disassemble the mounting frame from the fixed frame. Conversely, when there are many steel pipes to be connected, the third connecting frame can be engaged with the fixed frame via the mounting block, and the fixing bolt can be inserted into the fixed frame and the mounting block to lock the fixed frame and the mounting block, so that other steel pipes can be connected via the third connecting frame.

[0022] 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.

[0023] Please see Figure 1-5This utility model provides a technical solution: a connector for a building steel structure, including a first steel pipe 1, a connecting component sleeved at the middle position of the first steel pipe 1, the connecting component including a first connecting frame 2, the first connecting frame 2 sleeved on the outside of the first steel pipe 1, and mounting frames 3 fixedly connected to both the front and rear ends of the first steel pipe 1, and mounting plates 4 fixedly connected to the upper end of the mounting frames 3, second connecting frames 5 fixedly connected to both the upper and lower ends of the first connecting frame 2, reinforcing plates 6 fixedly connected to both the front and rear ends of the second connecting frame 5, second steel pipes 7 inserted into both the upper and lower ends of the second connecting frame 5, fixing frames 8 fixedly connected to both the left and right ends of the first connecting frame 2, and mounting blocks 9 engaged at the other end of the fixing frames 8, and a third connecting frame 10 fixedly connected to the other end of the mounting blocks 9, and fixing bolts 11 inserted into the front end of the fixing frames 8.

[0024] The upper end of the first connecting frame 2 has a through groove. Two mounting plates 4 are fixedly connected to the upper end of the mounting frame 3 at the through groove position. Two sets of bolts are inserted into the mounting plates 4, and nuts are fitted onto the ends of the bolts. Two washers are fitted onto the bolts. One washer abuts against the bolt and the mounting plate 4 at both ends, and the other washer abuts against the nut and the mounting plate 4. The two bolts are inserted into the mounting plates 4 in opposite directions to form symmetrical tension, avoiding unilateral force that could cause the mounting plate 4 to tilt or loosen. The washers (usually made of metal or elastic material) evenly distribute the tightening force of the bolts onto the mounting plates 4, preventing the steel pipe from deforming or the bolts from loosening due to excessive local pressure. The ends of the bolts are locked by nuts, forming a mechanical self-locking mechanism to prevent the bolts from loosening due to equipment vibration or long-term use. The upper and lower washers respectively restrict the axial movement of the bolts and nuts, further enhancing the anti-loosening effect. The effect is that the gasket acts as a buffer layer, preventing the bolts from directly pressing the edge of the through groove of the mounting plate 4 or the first connecting frame 2, avoiding local dents or cracks in the steel pipe. The gasket can reduce the friction between the bolts and the mounting plate 4, extending the service life of the bolts. The mounting frame 3 can be quickly disassembled by loosening the nut, which is convenient for subsequent maintenance or replacement of parts. The bolts, gaskets and nuts are all standard parts, which are easy to obtain and replace, reducing maintenance costs. The combination of bidirectional bolts and gaskets can effectively resist the vibration during equipment operation and prevent the connection from loosening. It is suitable for mounting plates 4 and the first connecting frame 2 of different thicknesses. It can be flexibly adapted by adjusting the number of gaskets or the bolt specifications. The two sets of bolts share the connection force. Even if one bolt is loose or damaged, the other set can still maintain the basic connection strength. The symmetrical arrangement of bolts makes the force on the mounting frame 3 more uniform, avoiding deformation of the connecting frame due to unilateral force.

[0025] The front end of the second connecting frame 5 has a through slot. Both ends of the reinforcing plate 6 are fixedly connected to the second connecting frame 5 and the first connecting frame 2. The reinforcing plate 6 is triangular in structure. Bolts are inserted into the second connecting frame 5, and nuts are fitted onto the bolts. The bolts penetrate to the second steel pipe 7. The second steel pipe 7 has slots that mate with the bolts. The second connecting frame 5 has evenly spaced slots that mate with the bolts. The triangular structure of the reinforcing plate 6 utilizes the geometric stability of triangles to significantly enhance the connection strength between the second connecting frame 5 and the first connecting frame 2, preventing deformation or displacement of the connecting frame due to external forces. The evenly spaced slots on the second connecting frame 5 mate with the bolts to ensure uniform distribution of connection force, avoid local stress concentration, and improve the overall load-bearing capacity of the structure. The two ends of the reinforcing plate 6 are fixed to the second connecting frame 5 and the first connecting frame 2 respectively, forming a "rigid support" that effectively resists deformation caused by external pressure or vibration. The bolts not only fix the second connecting frame 5 but also extend to the slots in the second steel pipe 7. In this design, the steel pipe and connecting frame are tightly integrated, further enhancing the overall structure's resistance to bending and torsion. The second connecting frame 5 or the second steel pipe 7 can be quickly disassembled by loosening the nuts, facilitating subsequent maintenance or component replacement. The slots on the second connecting frame 5 and the second steel pipe 7 match the bolts, eliminating the need for aligning complex structures during assembly and disassembly, making the operation simple and efficient. The tight fit between the bolts and slots effectively resists vibrations during equipment operation, preventing loosening of the connection. By adjusting the bolt specifications or the number of slots, different thicknesses of connecting frames or steel pipes can be flexibly adapted, making it suitable for various installation environments. Multiple bolts share the connection force, ensuring that even if one bolt loosens or is damaged, the others maintain basic connection strength. The evenly distributed bolts ensure more uniform stress on the second connecting frame 5, preventing deformation of the connecting frame due to unilateral stress. The bolt ends are locked with nuts, forming a mechanical self-locking mechanism to prevent bolt loosening due to equipment vibration or long-term use. The slots on the second steel pipe 7 restrict the axial movement of the bolts, further enhancing the anti-loosening effect.

[0026] The mounting block 9 is T-shaped, and the fixing frame 8 has a T-shaped slot that mates with the mounting block 9. The third connecting frame 10 is embedded in the fixing frame 8 via the mounting block 9. The outer surface of the fixing bolt 11 has evenly distributed threaded grooves, and both the fixing frame 8 and the mounting block 9 have threaded slots that mate with the fixing bolt 11. A ring is fixedly connected to the front end of the fixing bolt 11. The T-shaped structure of the mounting block 9 fits tightly with the T-shaped slot of the fixing frame 8, forming a mechanical engagement that effectively prevents the third connecting frame 10 from shifting or rotating under stress. The fixing bolt 11 is connected to the fixing frame 8 and the mounting block 9 via the threaded slot, further enhancing the connection strength and preventing loosening or detachment. The evenly distributed threaded grooves on the outer surface of the fixing bolt 11 mate with the threaded slots of the fixing frame 8 and the mounting block 9, forming a mechanical self-locking mechanism that maintains stability even under vibration or frequent loads. The ring at the front end of the fixing bolt 11 acts as a limiting structure to prevent the fixing bolt 11 from being over-tightened or loosened, improving the reliability of the connection. The fixing bolt 11 allows for quick disassembly of the third connecting frame 10, facilitating subsequent maintenance or component replacement. The standardized design of the threaded slot and fixing bolt 11 eliminates the need for complex tools during assembly and disassembly, making operation simple and efficient. The dual fixing method of the T-shaped slot and threaded connection effectively resists vibration during equipment operation and prevents loosening of the connection. By adjusting the thread specification or threaded slot depth of the fixing bolt 11, it can flexibly adapt to mounting blocks 9 or fixing frames 8 of different thicknesses, making it suitable for various installation environments. The T-shaped slot and threaded connection share the connection force, so even if one part (such as the thread) wears or loosens, the other part can still maintain the basic connection strength. The fixing bolts 11 are evenly distributed on the mounting blocks 9 and fixing frames 8, ensuring even distribution of connection force and avoiding local stress concentration. The T-shaped structure of the mounting block 9 cooperates with the slot of the fixing frame 8 to automatically guide the third connecting frame 10 to be accurately aligned, reducing installation errors. The threaded slot of the fixing bolt 11 restricts its rotation and axial movement, ensuring connection accuracy.

[0027] Working principle: The first steel pipe 1 serves as the main load-bearing structure, with the first connecting frame 2 sleeved in the middle, fixed by welding or tight fit. The first connecting frame 2, as the core connecting node, integrates the mounting frames 3 at the front and rear ends, the second connecting frames 5 at the top and bottom ends, and the fixing frames 8 at the left and right ends into a whole, forming a stable frame structure. The mounting frames 3 are fixed to the front and rear ends of the first steel pipe 1, and their upper ends are connected by mounting plates 4 and bolts. The bolts pass through the through grooves of the mounting plates 4 and are locked with nuts. Washers distribute pressure to prevent the mounting plates 4 from loosening or deforming. This design allows the mounting frames 3 to withstand tension or pressure from the front end, while facilitating disassembly and maintenance. The second connecting frames 5 are fixed to the top and bottom ends of the first connecting frame 2, with through grooves opened at their front ends for bolts to be inserted and connected to the second steel pipe 7. The reinforcing plate 6 has a triangular structure, with both ends fixed to the second connecting frames. On the first connecting frame 2 and the second connecting frame 5, the triangular stability is used to enhance the bending resistance. The bolts pass through the slots of the second connecting frame 5 and the second steel pipe 7 to form a rigid connection, preventing the second steel pipe 7 from shifting relative to the first connecting frame 2. The fixing frame 8 is fixed at the left and right ends of the first connecting frame 2, and the mounting block 9 (T-shaped structure) is embedded inside. The T-shaped part of the mounting block 9 is embedded in the T-shaped slot of the fixing frame 8 to achieve initial positioning and limiting. The fixing bolt 11 is inserted into the threaded slot of the fixing frame 8 and the mounting block 9, and is further fixed by the thread self-locking effect to prevent the mounting block 9 from coming out. The outer surface of the fixing bolt 11 is provided with a threaded groove, which cooperates with the threaded slot of the fixing frame 8 and the mounting block 9. When the fixing bolt 11 is rotated, the thread engagement generates axial tension, which firmly presses the mounting block 9 into the fixing frame 8. The ring at the front end serves as a limiting structure to prevent the fixing bolt 11 from being over-tightened or loosened.
