Description

Technical Field

[0001] This utility model relates to the field of steel structure frame connection technology, and in particular to a steel structure frame connection structure. Background Technology

[0002] In the field of steel structure engineering, the reliable connection between beams directly affects the stability and safety of the overall structure. Common connection methods include welding and bolting. In bolting, when connecting the crossbeam and the main beam, the mounting holes of the connecting plates on both sides must be fully aligned so that the bolts can pass through the mounting holes for fixing.

[0003] However, traditional connection structures lack preliminary positioning components. During high-altitude operations, the crossbeams are easily affected by wind and hoisting sway, making it difficult to stabilize quickly. This results in time-consuming and labor-intensive hole-aligning processes, increasing labor and machinery costs and posing safety hazards for high-altitude adjustments. Furthermore, installation relies entirely on hoisting accuracy and worker experience, which can easily lead to installation difficulties due to accumulated errors, affecting project progress and quality. Therefore, we propose a steel frame connection structure to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the lack of preliminary positioning function in traditional steel structure connections, the easy swaying of crossbeams during high-altitude operations leading to difficulties in hole alignment, low installation efficiency, high cost, and safety hazards. Therefore, a steel structure frame connection structure is proposed.

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

[0006] A steel frame connection structure includes a main beam and an I-beam crossbeam. The main beam and the crossbeam are connected by a connection structure, which includes a connecting beam of I-beam structure. The connecting beam is welded to one side of the main beam. Connecting plates are fixedly welded to both sides of the connecting beam and the crossbeam. The connecting plates on the connecting beam and the connecting plates on the crossbeam are provided with corresponding mounting holes. High-strength bolts are installed in the corresponding mounting holes. Limit nuts are threaded at both ends of the high-strength bolts.

[0007] A positioning component is provided at one end of the connecting beam near the crossbeam. The positioning component includes a limiting block located at the end of the connecting beam away from the main beam. A clearance groove is provided on the top of the limiting block. A clearance opening is provided on the lower flange of the crossbeam near the connecting beam. The web of the crossbeam is inserted into the clearance groove from top to bottom.

[0008] In one possible design, the positioning component further includes two threaded holes at the bottom of the limiting block, and the connecting beam has through holes corresponding to the two threaded holes on its lower flange. Each of the two through holes is provided with a limiting bolt, which passes through the through hole and is threadedly connected to the threaded hole.

[0009] In one possible design, positioning blocks are fixedly installed on both sides of the clearance groove at the top of the limiting block, and a positioning groove corresponding to the positioning block is opened at the bottom of the upper flange of the connecting beam, and the positioning block is horizontally inserted into the positioning groove.

[0010] In one possible design, the limiting block has anti-detachment grooves on both sides of the inner wall of the relief groove, and anti-detachment blocks that match the anti-detachment grooves are fixedly connected to both sides of the web of the crossbeam, and the anti-detachment blocks are inserted into the anti-detachment grooves.

[0011] In one possible design, the upper flange of the crossbeam has a slot corresponding to the positioning block, and the positioning block is embedded in the slot.

[0012] In one possible design, both openings of the anti-detachment grooves are set as bevels.

[0013] In one possible design, the top and bottom of the connecting beam are fixedly connected with reinforcing ribs, one side of which is welded to the main beam.

[0014] In this application, firstly, the connecting beam is fixed to the side of the main beam by welding. During the welding process, the reinforcing ribs at the top and bottom of the connecting beam are simultaneously welded to the main beam to enhance the rigidity of the joint area. Then, the limiting block is embedded into the end of the connecting beam by horizontal sliding. After the threaded hole at its bottom is aligned with the through hole of the lower flange of the connecting beam, the limiting bolt is tightened through to fix it, so as to realize the quick and easy disassembly and installation of the limiting block, which is convenient for maintenance and replacement. At the same time, the two positioning blocks at the top of the limiting block are simultaneously embedded into the positioning groove of the upper flange of the connecting beam to form multi-directional constraints and prevent the limiting block from being displaced during use.

[0015] Next, the crossbeam is installed. When the crossbeam is hoisted, the clearance opening on its bottom flange is vertically aligned with the clearance groove on the top of the limiting block. During the fall of the crossbeam, its web is vertically embedded along the clearance groove, and the anti-detachment blocks on both sides of the web fall into the anti-detachment groove. The inclined guide structure at the opening of the anti-detachment groove enables smooth embedding and avoids jamming. When the weight of the crossbeam is completely borne by the limiting block, its web contacts the bottom of the clearance groove, and its two side connecting plates are naturally aligned with the connecting plates on the connecting beam. The gravity is used to automatically complete the in-plane positioning, eliminating the manual adjustment process.

[0016] Finally, the operator inserts high-strength bolts through the mounting holes on both sides of the connecting plates and uses a torque wrench to tighten the limit nuts in the prescribed sequence to form a rigid friction connection node, ensuring effective load transfer. At this time, the load borne by the crossbeam is transferred to the connecting beam through the connecting plates and bolt group, and finally to the main beam structure, realizing multi-path force transmission and improving the safety redundancy of the node. At the same time, the positioning component continues to play a limiting role during use, preventing the bolt rod from colliding and wearing with the hole wall under lateral load, extending the service life of the connection node and reducing maintenance requirements.

[0017] Beneficial effects: In this utility model, the steel frame connection structure, by setting a limiting block with a clearance groove to cooperate with the clearance opening on the flange of the crossbeam, allows the web of the crossbeam to quickly and vertically fall into the groove, achieving initial positioning; this structure effectively restricts the horizontal movement of the crossbeam, provides a hole-fitting foundation for subsequent bolt connections, greatly reduces high-altitude adjustment time, reduces operational risks, and improves installation efficiency;

[0018] In this utility model, the steel frame connection structure enhances the overall rigidity and anti-slip capability of the positioning components through the synergistic effect of the limiting bolts, positioning blocks and anti-detachment blocks; the detachable design of the limiting blocks facilitates maintenance and replacement, and the anti-detachment groove and inclined opening guide structure make the web plate insertion smoother, avoid jamming and wear, improve reusability and operational error tolerance, and adapt to various working conditions.

[0019] In this utility model, the steel frame connection structure enhances the rigidity of the welded joint between the connecting beam and the main beam by reinforcing ribs, thus dispersing local stress; the interlocking of the anti-detachment block and the anti-detachment groove further constrains the displacement of the crossbeam web, resulting in a clear overall force transmission path, reliable connection, good shear and bending resistance, and extended service life of the structure.

[0020] In this invention, the limiting block with a clearance groove cooperates with the clearance opening of the crossbeam to achieve rapid vertical positioning of the crossbeam web, effectively restricting horizontal movement and providing a foundation for bolt alignment, significantly improving installation efficiency and safety. Through the synergistic effect of the limiting bolt, positioning block, and anti-detachment block, the rigidity and anti-misalignment capability of the positioning component are enhanced. The detachable design and inclined guide improve the operational error tolerance and reusability. The reinforcing rib enhances the node rigidity, and the engagement of the anti-detachment block and the groove clearly defines the force transmission path, giving the connection good shear and bending resistance and extending its service life.

[0026] 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.

[0027] In one embodiment: Refer to Figure 1-4 A connecting structure includes a main beam 1 and an I-beam crossbeam 2, which are connected by the connecting structure. The connecting structure includes an I-beam connecting beam 3, which is welded to one side of the main beam 1. Reinforcing ribs 9 are fixedly connected to the top and bottom of the connecting beam 3. When the connecting beam 3 is welded to the main beam 1, one side of each reinforcing rib 9 is welded to the main beam 1. This enhances the stiffness of the joint area, disperses local stress, and makes the welded joint between the connecting beam 3 and the main beam 1 more stable.

[0028] A positioning component is provided at the end of the connecting beam 3 near the crossbeam 2. When the crossbeam 2 and the connecting beam 3 are assembled, the positioning component performs initial positioning and fixation to prevent the crossbeam 2 from shaking and causing the corresponding mounting holes to misalign, thus affecting the installation. The positioning component includes a limiting block 5 located at the end of the connecting beam 3 away from the main beam 1. The top of the limiting block 5 has a clearance groove 501, and the lower flange of the crossbeam 2 near the connecting beam 3 has a clearance opening 201. When the crossbeam 2 and the connecting beam 3 are assembled, the web of the crossbeam 2 is inserted into the clearance groove 501 from top to bottom. This mating method allows the web of the crossbeam 2 to quickly and vertically fall into the groove, achieving initial positioning, effectively limiting the horizontal movement of the crossbeam 2, providing a foundation for subsequent bolt connection, significantly reducing high-altitude adjustment time, reducing operational risks, and improving installation efficiency.

[0029] The positioning assembly also includes two threaded holes at the bottom of the limiting block 5. The lower flange of the connecting beam 3 has through holes 301 corresponding to the two threaded holes, and each through hole 301 contains a limiting bolt 12. When the limiting block 5 slides horizontally into the end of the connecting beam 3, the two limiting bolts 12 pass through the corresponding through holes 301 and are threadedly connected to the corresponding threaded holes, enabling quick and easy installation and maintenance of the limiting block 5. Positioning blocks 6 are fixedly installed on both sides of the clearance groove 501 at the top of the limiting block 5. The bottom of the upper flange of the connecting beam 3 has positioning grooves 7 corresponding to the two positioning blocks 6. When the limiting block 5 slides horizontally into the end of the connecting beam 3, the two positioning blocks 6 are horizontally inserted into the corresponding positioning grooves 7, forming multi-directional constraints to prevent displacement of the limiting block 5 during use and enhance the overall rigidity and anti-fault capability of the positioning assembly.

[0030] The limiting block 5 has anti-detachment grooves 502 on both inner walls of the relief groove 501. Anti-detachment blocks 8, matching the two anti-detachment grooves 502, are fixedly connected to both sides of the web of the crossbeam 2. When the web of the crossbeam 2 is inserted into the relief groove 501 from top to bottom, the two anti-detachment blocks 8 are inserted into their corresponding anti-detachment grooves 502, preventing the crossbeam 2 from horizontally detaching and further constraining the displacement of the web of the crossbeam 2. This makes the overall force transmission path clearer, the connection more reliable, and gives the structure good shear and bending resistance, extending its service life. The openings of the two anti-detachment grooves 502 are both designed as bevels, increasing the width of the openings to facilitate the insertion of the two anti-detachment blocks 8 into their corresponding anti-detachment grooves 502, avoiding jamming and wear, improving reusability and operational error tolerance, and adapting to various working conditions.

[0031] The upper flange of the crossbeam 2 has slots 11 corresponding to the two positioning blocks 6. When the web of the crossbeam 2 is inserted into the clearance groove 501 from top to bottom, the two positioning blocks 6 are respectively embedded in the corresponding slots 11, which further enhances the positioning and fixing effect of the crossbeam 2.

[0032] This application can be used in the field of steel structure frame connection technology, and can also be used in other fields applicable to this application.

[0033] In another embodiment: Reference Figure 1-3Based on Embodiment 1, an improvement is made: a steel frame connection structure, applied in the field of steel frame connection technology, wherein connecting plates 4 are fixedly welded to both sides of the connecting beam 3 and the crossbeam 2. Corresponding mounting holes are opened on the two connecting plates 4 on the connecting beam 3 and the two connecting plates 4 on the crossbeam 2, and high-strength bolts 10 are installed in the corresponding mounting holes. Each high-strength bolt 10 has a limit nut threaded onto both ends. When the weight of the crossbeam 2 is entirely borne by the limit block 5, its web contacts the bottom of the relief groove 501, and its two side connecting plates 4 are naturally aligned with the connecting plates 4 on the connecting beam 3, automatically completing in-plane positioning using gravity, eliminating the need for manual adjustment. The operator inserts the high-strength bolts 10 through the mounting holes of the two side connecting plates 4 and tightens the limit nuts in the prescribed sequence using a torque wrench, forming a rigid friction-type connection node to ensure effective load transfer. At this time, the load borne by the crossbeam 2 is transferred to the connecting beam 3 through the connecting plates 4 and the bolt group, and finally to the main beam 1 structure, realizing multi-path force transmission and improving the safety redundancy of the node. Meanwhile, the positioning component continuously plays a limiting role during use, preventing the bolt rod from colliding and wearing with the hole wall under lateral loads, extending the service life of the connection node and reducing maintenance needs.
