Description

Technical Field

[0001] This utility model relates to the field of building technology, specifically to an irregular box-shaped steel beam-column structure. Background Technology

[0002] In modern construction engineering, steel structures have become the mainstream structural form for large-span, high-rise buildings due to their advantages such as light weight, high strength, and short construction period. As the core load-bearing components of steel structures, the performance of beam-column structures directly determines the overall safety, economy, and spatial applicability of the building. Currently, commonly used beam-column structures in the construction field mainly include H-shaped steel beams and columns, ordinary box-section steel beams and columns, and concrete-encased steel beams and columns. Among these, ordinary box-section steel beams and columns are widely used in heavy-load and complex stress scenarios due to their good torsional resistance and high load-bearing capacity.

[0003] The utility model patent with publication number CN223119255U discloses a steel beam and box column anti-bending joint, which includes a box column body, a steel beam body, and connecting components arranged on both sides of the steel beam body. The connecting plate in the connecting components cooperates with the longitudinal and transverse reinforcing frames to form strong transverse and longitudinal support for the steel beam body. Through multiple reinforcements, the beam and column can be subjected to forces in multiple directions, which not only ensures the reliability of the connection and the anti-bending effect, but also has strong practicality.

[0004] However, there are still obvious shortcomings in these types of patents and in the actual application of box-type steel beams and columns. Most of their docking seats are fixed structures that are pre-welded and installed, which cannot be quickly adjusted and adapted to the actual working conditions on site, resulting in a lack of installation flexibility and seriously restricting the improvement of construction efficiency. Utility Model Content

[0005] The purpose of this utility model is to provide an irregular box-shaped steel beam and column structure, which aims to improve the problem that most of the connecting seats on existing box-shaped steel beams and columns are pre-welded and installed, making it impossible to quickly adjust and install them according to the on-site construction conditions, thus affecting construction efficiency.

[0013] Preferably, the sliding connection part has a drive joint at one end facing outward, and the drive joint has a drive groove in the middle, which is used to drive the limit screw to rotate through the drive groove.

[0014] Preferably, the inner surfaces of the end panel, side baffle, and sealing plate are all fixedly connected with a sound insulation and noise reduction layer by structural adhesive, and the sound insulation and noise reduction layer is made of porous sound-absorbing cotton.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The following description, in conjunction with the accompanying drawings and specific embodiments, provides further details:

[0029] Example 1

[0030] like Figure 1 and Figure 2As shown, an irregular box-shaped steel beam-column structure includes two end panels 1, with two web plates 2 between them. Side baffles 3 are symmetrically arranged on both sides of the two end panels 1. Sealing plates 4 are provided at the top and bottom of the two end panels 1. The sealing plates 4, end panels 1, side baffles 3, and web plates 2 are all welded together. This structure facilitates welding to form the entire box-shaped steel beam-column. The web plates 2 are used to reinforce the box-shaped steel beam-column from the inside, thereby ensuring that the entire box-shaped steel beam-column has sufficient strength. The outer side of the side baffle 3 is slidably connected to the docking plate 5. The docking plate 5 is used to dock with external components, breaking the limitation of the traditional docking seat being "pre-welded and not adjustable". It realizes the on-site adjustment and installation of the docking seat without the need to fix the position in advance, flexibly adapting to on-site construction errors or changes in demand, and greatly improving construction efficiency. The docking plate 5 and the side baffle 3 are connected by a limiting screw 6. The limiting screw 6 is a "position locking component of docking plate 5" - when the docking plate 5 is adjusted to the designated position, tightening the limiting screw 6 can fix the docking plate 5 and prevent it from shifting.

[0031] like Figure 3 As shown, multiple reinforcing plates 21 are evenly arranged from top to bottom on the side of the web plate 2 facing the side baffle 3. The reinforcing plates 21 are welded to the side baffle 3. The reinforcing plates 21, as the "lateral reinforcing members" of the structure, are welded at equal intervals between the outer end of the web plate 2 and the inner end of the end panel 1. At the same time, the side baffle 3 is welded to the outer end. The core function is to disperse the stress at the connection between the web plate 2 and the end panel 1, and at the same time provide a stable welding foundation for the side baffle 3. This solves the problem of "stress concentration" at the connection between the web plate 2 and the end panel 1, improves the lateral load-bearing capacity and bending resistance of the structure, and ensures that the side baffle 3 does not shift or loosen after installation, thus strengthening the connection stability between the side baffle 3 and the main structure.

[0032] like Figure 4 As shown, support plates 31 are symmetrically provided on the upper and lower parts of both sides of the side baffle 3. The support plates 31 are L-shaped and serve as the "support and guide frame for the docking plate 5". They are symmetrically welded to the outer ends of both sides of the side baffle 3. The inner side has a sliding groove 32 and nests the docking plate 5, bearing the load of the docking plate 5 and subsequent external connecting parts, and restricting the sliding direction of the docking plate 5. The support plates 31 provide stable support for the sliding adjustment of the docking plate 5, ensuring that the docking plate 5 can only move in a straight line in the specified direction, avoiding deviation or jamming during the adjustment process, and ensuring the installation guidance and accuracy of the docking components. In addition, the support plates 31 have a longitudinal sliding groove 32, which is used to limit the sliding path of the docking plate 5 and lock the position of the docking plate 5 in conjunction with the limit screw 6. This enables the adjustable sliding of the docking plate 5, allowing the docking plate 5 to be flexibly adjusted according to the on-site construction requirements. The track constraint ensures that the docking plate 5 slides smoothly, avoiding deviation that affects the docking accuracy, and providing a basis for subsequent position locking.

[0033] like Figure 5As shown, the mating plate 5 is inserted between two symmetrically arranged support plates 31, and symmetrical mating side plates 53 are provided on both sides of the outward-facing side of the mating plate 5. The mating side plates 53 increase the contact area between the mating plate 5 and the external components, dispersing the local load at the mating point. This avoids excessive local stress, deformation, or damage to the mating plate 5 due to insufficient contact area; it also improves the load transfer efficiency at the mating point, ensuring the firmness and pull-out resistance of the external components after connection with the mating plate 5. The mating plate 5 has multiple mating holes 51 evenly distributed between the two mating side plates 53. The mating holes 51 provide installation channels for fixing bolts and also serve as a reference for positioning and drilling the side baffle 3. This achieves precise connection between the mating plate 5 and the external components, and the equidistant design ensures uniform stress distribution at multiple connection points; at the same time, it simplifies the drilling process of the side baffle 3, allowing for rapid positioning using the mating holes 51 as a reference, improving installation accuracy and efficiency. Threaded grooves 52 are provided in the middle of both sides of the mating plate 5, and the limiting screw 6 is threadedly connected to the threaded grooves 52.

[0034] like Figure 6 As shown, the outer end of the limiting screw 6 is provided with a sliding connection part 61, which is aligned with the slide groove 32 to ensure that the mating plate 5 moves stably up and down along the slide groove 32. The outer end of the sliding connection part 61 is provided with a drive joint 62, and the middle of the drive joint 62 is provided with a drive groove 63, which is used to drive the limiting screw 6 to rotate through the drive groove 63.

[0035] like Figure 1 and Figure 2 As shown, the inner surfaces of end panel 1, side baffle 3, and sealing plate 4 are all fixedly connected with sound insulation and noise reduction layers using structural adhesive. These layers are made of porous sound-absorbing cotton, thus providing excellent sound insulation for the entire box-type steel beam-column structure. The outer surfaces of end panel 1, side baffle 3, and sealing plate 4 are coated with a polyvinyl fluoride (PVC) anti-corrosion coating. The dry film thickness of the PVC anti-corrosion coating is 4-6 μm, and the coating surface has a matte finish. This PVC anti-corrosion coating effectively improves the corrosion resistance of the box-type steel beam-column structure.

[0036] Example 2

[0037] like Figure 1 and Figure 2As shown, an irregular box-shaped steel beam-column structure includes two end panels 1, with two web plates 2 between them. Side baffles 3 are symmetrically arranged on both sides of the two end panels 1. Sealing plates 4 are provided at the top and bottom of the two end panels 1. The sealing plates 4, end panels 1, side baffles 3, and web plates 2 are all welded together. This structure facilitates welding to form the entire box-shaped steel beam-column. The web plates 2 are used to reinforce the box-shaped steel beam-column from the inside, thereby ensuring that the entire box-shaped steel beam-column has sufficient strength. The outer side of the side baffle 3 is slidably connected to the docking plate 5. The docking plate 5 is used to dock with external components, breaking the limitation of the traditional docking seat being "pre-welded and not adjustable". It realizes the on-site adjustment and installation of the docking seat without the need to fix the position in advance, flexibly adapting to on-site construction errors or changes in demand, and greatly improving construction efficiency. The docking plate 5 and the side baffle 3 are connected by a limiting screw 6. The limiting screw 6 is a "position locking component of docking plate 5" - when the docking plate 5 is adjusted to the designated position, tightening the limiting screw 6 can fix the docking plate 5 and prevent it from shifting.

[0038] like Figure 3 As shown, multiple reinforcing plates 21 are evenly arranged from top to bottom on the side of the web plate 2 facing the side baffle 3. The reinforcing plates 21 are welded to the side baffle 3. The reinforcing plates 21, as the "lateral reinforcing members" of the structure, are welded at equal intervals between the outer end of the web plate 2 and the inner end of the end panel 1. At the same time, the side baffle 3 is welded to the outer end. The core function is to disperse the stress at the connection between the web plate 2 and the end panel 1, and at the same time provide a stable welding foundation for the side baffle 3. This solves the problem of "stress concentration" at the connection between the web plate 2 and the end panel 1, improves the lateral load-bearing capacity and bending resistance of the structure, and ensures that the side baffle 3 does not shift or loosen after installation, thus strengthening the connection stability between the side baffle 3 and the main structure.

[0039] like Figure 4 As shown, support plates 31 are symmetrically provided on the upper and lower parts of both sides of the side baffle 3. The support plates 31 are L-shaped and serve as the "support and guide frame for the docking plate 5". They are symmetrically welded to the outer ends of both sides of the side baffle 3. The inner side has a sliding groove 32 and nests the docking plate 5, bearing the load of the docking plate 5 and subsequent external connecting parts, and restricting the sliding direction of the docking plate 5. The support plates 31 provide stable support for the sliding adjustment of the docking plate 5, ensuring that the docking plate 5 can only move in a straight line in the specified direction, avoiding deviation or jamming during the adjustment process, and ensuring the installation guidance and accuracy of the docking components. In addition, the support plates 31 have a longitudinal sliding groove 32, which is used to limit the sliding path of the docking plate 5 and lock the position of the docking plate 5 in conjunction with the limit screw 6. This enables the adjustable sliding of the docking plate 5, allowing the docking plate 5 to be flexibly adjusted according to the on-site construction requirements. The track constraint ensures that the docking plate 5 slides smoothly, avoiding deviation that affects the docking accuracy, and providing a basis for subsequent position locking.

[0040] like Figure 5As shown, the mating plate 5 is inserted between two symmetrically arranged support plates 31, and symmetrical mating side plates 53 are provided on both sides of the outward-facing side of the mating plate 5. The mating side plates 53 increase the contact area between the mating plate 5 and the external components, dispersing the local load at the mating point. This avoids excessive local stress, deformation, or damage to the mating plate 5 due to insufficient contact area; it also improves the load transfer efficiency at the mating point, ensuring the firmness and pull-out resistance of the external components after connection with the mating plate 5. The mating plate 5 has multiple mating holes 51 evenly distributed between the two mating side plates 53. The mating holes 51 provide installation channels for fixing bolts and also serve as a reference for positioning and drilling the side baffle 3. This achieves precise connection between the mating plate 5 and the external components, and the equidistant design ensures uniform stress distribution at multiple connection points; at the same time, it simplifies the drilling process of the side baffle 3, allowing for rapid positioning using the mating holes 51 as a reference, improving installation accuracy and efficiency. Threaded grooves 52 are provided in the middle of both sides of the mating plate 5, and the limiting screw 6 is threadedly connected to the threaded grooves 52.

[0041] like Figure 6 As shown, the outer end of the limiting screw 6 is provided with a sliding connection part 61, which is aligned with the slide groove 32 to ensure that the mating plate 5 moves stably up and down along the slide groove 32. The outer end of the sliding connection part 61 is provided with a drive joint 62, and the middle of the drive joint 62 is provided with a drive groove 63, which is used to drive the limiting screw 6 to rotate through the drive groove 63.

[0042] like Figure 1 and Figure 2 As shown, the inner surfaces of end panel 1, side baffle 3, and sealing plate 4 are all fixedly connected with sound insulation and noise reduction layers using structural adhesive. These layers are made of porous sound-absorbing cotton, thus providing excellent sound insulation for the entire box-type steel beam column. The outer surfaces of end panel 1, side baffle 3, and sealing plate 4 are all coated with a zinc-aluminum alloy anti-corrosion coating. The dry film thickness of this coating is 100-150 μm, and graphene anti-corrosion additives are attached to its surface. This anti-corrosion structure significantly enhances the corrosion resistance of the entire box-type steel beam column, thereby extending its service life.

[0043] Working Principle: This irregular box-shaped steel beam-column structure uses welded assembly as its basic frame. Through the collaboration of multiple components, it achieves comprehensive functions such as strength assurance, flexible connection, sound insulation and noise reduction, and corrosion protection. Two end panels 1 serve as the supporting foundation, with two web plates 2 installed between them to strengthen the overall strength from within the structure. Symmetrical side baffles 3 on both sides of the end panels 1, along with the top and bottom sealing plates 4, are welded to form a closed box structure, ensuring the integrity of the frame. Reinforcing plates 21, evenly distributed from top to bottom on the side of the web plate 2 facing the side baffles 3, are welded to the web plate 2 and side baffles 3 respectively. This not only disperses the stress at the connection between the web plate 2 and the end panels 1, solving the stress concentration problem to improve lateral load-bearing capacity and bending resistance, but also provides stable support for the side baffles 3, preventing them from shifting or loosening after installation. The mating plate 5 on the outer side of the side baffle 3 is adjusted up and down by sliding on the L-shaped support plate 31 symmetrically welded to the side baffle 3. The sliding groove 32 on the inner side of the support plate 31 limits the sliding path of the mating plate 5 to avoid offset and jamming during adjustment. When the mating plate 5 is adjusted to the position that meets the on-site construction requirements, the limiting screw 6 is locked by threading the threaded groove 52 on the side of the mating plate 5. The sliding connection part 61 of the limiting screw 6 is aligned with the sliding groove 32 to ensure movement stability. The driving groove 63 of its outer end drive connector 62 facilitates the rotation and tightening of the screw, breaking the limitation of the traditional mating seat being pre-welded and not adjustable. The mating side plate 53 on the mating plate 5 increases the contact area with external components to distribute local loads and prevent the mating plate 5 from being damaged due to concentrated force deformation. The equidistantly distributed mating holes 51 not only provide installation channels for fixing bolts and ensure uniform force distribution at multiple connection points, but also serve as a reference for positioning and drilling of the side baffle 3, improving installation accuracy and efficiency. Meanwhile, the porous sound-absorbing cotton material sound insulation and noise reduction layer, which is fixed to the inner sides of the end panel 1, side baffle 3 and sealing plate 4 with structural adhesive, effectively blocks the transmission of sound and gives the structure a good sound insulation effect; the outer surface is first sprayed with a zinc-aluminum alloy anti-corrosion coating containing graphene anti-corrosion additives or a polyvinyl fluoride anti-corrosion coating with a matte finish, to improve the structure's anti-corrosion ability, extend its service life, and ultimately achieve a high-efficiency unity of structural mechanical properties, construction flexibility and environmental adaptability.

[0044] In summary, compared with the prior art, the mating holes 51 of this utility model are equidistantly opened at the outer end of the mating plate 5, and the side baffle 3 can be positioned and drilled through the mating holes 51; the mating plate 5 is nested inside the support plate 31, allowing the mating plate 5 to slide linearly along the support plate 31; the mating plate 5 and the slide groove 32 are connected by a limit screw 6 through a thread, and the position of the mating plate 5 can be easily locked through the limit screw 6; the above-mentioned solutions make it easy to adjust and install the mating seats on the box-type steel beam column on-site, effectively improving work efficiency.

[0045] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
