Abstract
Description
Technical Field
[0001] This invention relates to the field of component connection technology in building engineering, and specifically to a connection method for an integrated steel plate wall. Background Technology
[0002] The connection between steel plate walls and steel structure buildings refers to the structural form in which steel plate walls are reliably fixed and force-transmitted to the main components of steel structure buildings such as beams, columns, and foundations through pre-set connection nodes. Its core is to form a collaborative working system between the steel plate walls and the main steel structure through high-strength bolt connections, welding connections, or bolt-weld hybrid connections, so as to effectively transfer horizontal and vertical loads, disperse stress concentration, and ensure the overall stability, stiffness, and seismic and lateral displacement resistance of the structure. The connection nodes must meet the requirements of direct force transmission, reasonable structure, convenient construction, and compliance with relevant steel structure design codes.
[0003] In related technologies, there are generally three connection methods for steel plate walls to steel beams, floor slabs, and concrete shear walls. Because cement fiberboard is laminated on both sides of the steel plate wall, the component itself forms a closed section, making it impossible to achieve rapid connection with steel beams using traditional high-strength bolts. Furthermore, for connections to basement concrete shear walls, it is impossible to guarantee sufficient vibration of the concrete in the shear wall below the steel plate wall, thus affecting the pouring and load-bearing performance of the concrete shear wall. Summary of the Invention
[0004] This invention provides a method for connecting integrated steel plate walls to solve the problem that steel plate walls cannot be quickly connected and assembled in steel structure buildings.
[0005] This invention provides a method for connecting integrated steel plate walls, suitable for connecting integrated steel plate walls, the integrated steel plate wall comprising: Steel plate wall; A first steel beam and a second steel beam are respectively disposed on both sides of the steel plate wall along the first direction, and the steel plate wall is respectively connected to the first steel beam and the second steel beam; The floor slab is disposed between the steel plate wall and the second steel beam; A connecting end plate is provided through the floor slab along the first direction and extends along the direction close to the steel plate wall. One end of the connecting end plate is connected to the second steel beam, and the other end of the connecting end plate is connected to the steel plate wall. Alternatively, a concrete shear wall is connected to the steel plate wall. The concrete shear wall is provided with embedded plates, which are spaced apart at the top of the concrete shear wall. Backfill steel plates are provided between adjacent embedded plates, and the spacing between the backfill steel plates and the adjacent embedded plates is adapted to each other. The connection methods for integrated steel plate walls include: the connection steps between the steel plate wall and the first steel beam; the connection steps between the steel plate wall and the floor slab and the second steel beam; and the connection steps between the steel plate wall and the concrete shear wall.
[0006] Beneficial effects: By clarifying the composition and connection relationships of the integrated steel plate wall, the problems of difficult connection and adaptation and scattered force system of traditional integrated steel plate walls in steel structure buildings are solved, providing key support for the overall structural stability and efficient construction. Addressing the problem of unilateral force imbalance that easily occurs when connecting traditional steel plate walls and steel beams, the first and second steel beams are respectively set on both sides of the steel plate wall along the first direction and are both connected to the steel plate wall, forming a symmetrical double-sided support structure. This design allows for the even distribution of horizontal and vertical loads from the steel plate wall to the steel beams on both sides, preventing localized deformation of the steel plate wall and stress overload of the steel beams caused by concentrated stress on one side. This significantly improves the load-bearing performance of the superstructure and matches the high requirements of steel structure buildings for overall lateral stiffness and seismic resistance. In the connection between the steel plate wall and the floor slab, the connecting end plate penetrates the floor slab and extends into the steel plate wall. This end plate creates a rigid connection between the floor slab and the steel plate wall, ensuring that the floor load is transferred to the steel plate wall and the second steel beam through the end plate, preventing cracking of the floor slab due to insufficient support. Regarding the vibration challenges when connecting to concrete shear walls, traditional embedded plates often hinder vibration due to insufficient gaps, leading to concrete... The soil compaction was insufficient; however, the gaps formed by the pre-embedded plates could accommodate the vibrator, ensuring the quality of concrete pouring; the subsequent backfill steel plates could fill the gaps, making the pre-embedded plates form a continuous force-bearing surface, avoiding force transmission breakpoints, ensuring that the load is evenly transferred to the shear wall, preventing local stress concentration from causing structural damage, clarifying the complete connection process of the integrated steel plate wall, systematically covering the key connection links with the first steel beam, floor slab, second steel beam, and concrete shear wall, providing clear and standardized methodological guidance for construction, ensuring that the connection operation proceeds in an orderly manner, avoiding construction errors or connection failures caused by chaotic processes, and helping to carry out standardized and efficient engineering construction.
[0007] In one optional embodiment, the connecting end plate has a circular hole and a first bolt hole, the circular hole being used for the reinforcing bars of the floor slab to pass through, and the first bolt hole being adapted for the second connector to pass through.
[0008] Beneficial effects: The round holes in the connecting end plate allow the floor slab reinforcement to pass through smoothly, preventing the connecting end plate from obstructing the normal arrangement of the floor slab reinforcement and ensuring the structural integrity and load-bearing performance of the floor slab; the first bolt hole provides a precise installation channel for the second connector, ensuring that the steel plate wall, floor slab, and second steel beam can be firmly and securely fastened through the connector, which not only takes into account the continuity of floor slab construction, but also ensures the reliability and stability of the connection between the three, thus enhancing the practical value of the connection structure.
[0009] In one alternative embodiment, the gap between the embedded plates is larger than the diameter of the vibrator to meet the requirement of vibrating the vibrator inside the concrete shear wall.
[0010] Beneficial effects: The gap between the embedded plates is larger than the diameter of the vibrator, which allows the vibrator to be easily inserted into the concrete shear wall for thorough vibration. This completely solves the problem of insufficient concrete compaction caused by the small gap between traditional embedded plates. It effectively avoids problems such as insufficient strength and reduced load-bearing performance caused by insufficient concrete vibration, and provides key guarantees for the structural quality and subsequent connection reliability of the concrete shear wall.
[0011] In one alternative embodiment, the backfill steel plate is welded to the adjacent embedded plate, the backfill steel plate and the embedded plate are kept on the same plane, and the backfill steel plate is used to fill the gap between the embedded plates.
[0012] Beneficial effects: The backfill steel plate is connected to the adjacent embedded plate by welding, which not only tightly fills the gap between the embedded plates, but also keeps them on the same plane, so that the originally separate embedded plates form a complete and continuous stress surface. This ensures that the force is evenly transmitted when the steel plate wall is connected to the concrete shear wall, which significantly improves the shear bearing capacity and overall stress performance of the connection. At the same time, the welding connection method is stable and reliable, avoiding weak links in the gaps.
[0013] In one optional embodiment, a third connecting plate is provided on the embedded plate, and a second connecting plate is provided on the side of the steel plate wall near the third connecting plate. The third connecting plate and the second connecting plate are provided with second bolt holes, and the second connecting piece is connected to the second bolt hole.
[0014] Beneficial effects: The cooperation between the third connecting plate and the second connecting plate, as well as the corresponding second bolt holes, provides a precise installation fit point for the second connector, enabling precise alignment and firm connection between the steel plate wall and the embedded plate, forming a clear and reliable force transmission path. This ensures that the load borne by the steel plate wall can be effectively transferred to the concrete shear wall, avoiding poor force transmission or stress concentration at the connection point, and significantly improving the stability and load-bearing capacity of the connection.
[0015] In one alternative embodiment, the third connecting plate is provided with stiffening ribs.
[0016] Beneficial effects: Adding stiffening ribs to the third connecting plate can significantly improve the overall stiffness and deformation resistance of the connecting plate, effectively preventing buckling, excessive deformation or damage when the connecting plate is subjected to shear loads, further enhancing the stress stability and shear resistance of the connection between the steel plate wall and the concrete shear wall, and flexibly adapting to different shear bearing capacity requirements, thus extending the service life of the connection structure.
[0017] In one optional embodiment, the connection step between the steel plate wall and the first steel beam includes: setting a first connecting plate on the upper part of the steel plate wall, the first connecting plate and the first steel beam flange of the first steel beam having bolt holes, and using a first connector to pass through the bolt holes to achieve a tight connection between the steel plate wall and the first steel beam.
[0018] Beneficial effects: Targeting the closed section characteristics of the integrated steel plate wall, the use of the bolt holes of the first connecting plate and the flange of the first steel beam, combined with the use of the first connecting piece, successfully solved the problem of rapid connection of the closed section that traditional high-strength bolts could not achieve. It eliminates the need for complex on-site welding operations, simplifies the installation process, and greatly improves the connection efficiency between the steel plate wall and the upper steel beam. At the same time, the fastening connection method ensures the reliability of the connection and the structural stability of the two.
[0019] In one optional embodiment, the connection steps between the steel plate wall, the floor slab, and the second steel beam include: before the floor slab is poured, welding the connecting end plate to the flange of the second steel beam, so that the connecting end plate passes through the floor slab and extends to the second connecting plate of the steel plate wall; after the floor slab reinforcement passes through the connecting end plate, the floor slab is poured; after the floor slab is formed, the steel plate wall, the floor slab, and the second steel beam are fastened together by passing the second connector through the first bolt hole of the connecting end plate and the second connecting plate.
[0020] Beneficial effects: By pre-welding the connecting end plates and reserving round holes, the normal arrangement of floor slab reinforcement and the quality of floor slab pouring are ensured, and the precise connection between the connecting end plates and the steel plate wall and the second steel beam is achieved. After the floor slab is formed, it is fastened by the second connector. The process is simple and smooth, reducing interference from on-site cross-construction, shortening the construction period, and reducing construction costs. At the same time, it achieves integrated fastening of the steel plate wall, floor slab and the second steel beam, improving the overall structural performance.
[0021] In one optional embodiment, the connection steps between the steel plate wall and the concrete shear wall include: during the pouring of the concrete shear wall, pre-embedded plates are installed at intervals on its top with gaps reserved; a vibrator is passed through the gaps to vibrate the concrete inside the concrete shear wall; after vibration, a backfill steel plate is welded between adjacent pre-embedded plates to form a third connection, and the backfill steel plate and the pre-embedded plates are kept flush; a second connector passes through the second bolt hole of the third connecting plate on the pre-embedded plate and the second connecting plate of the steel plate wall to achieve a tight connection between the steel plate wall and the concrete shear wall.
[0022] Beneficial effects: First, the pre-embedded plates are set at intervals, which effectively solves the vibration problem during the pouring of concrete shear walls, ensuring the density of concrete and structural strength; then, the backfill steel plates form a complete load-bearing surface, ensuring the force transmission foundation of the connection parts; finally, the second connector achieves a tight connection, which not only ensures the reliability and force transmission effectiveness of the connection between the steel plate wall and the concrete shear wall, but also reduces the amount of on-site welding work, improves installation efficiency, and balances construction quality and construction convenience.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0027] The following is combined with Figures 1 to 3 The following describes embodiments of the present invention.
[0028] According to an embodiment of the present invention, a method for connecting an integrated steel plate wall is provided, comprising: a steel plate wall 4; a first steel beam 5 and a second steel beam 9, the first steel beam 5 and the second steel beam 9 being respectively disposed on both sides of the steel plate wall 4 along a first direction, the steel plate wall 4 connecting the first steel beam 5 and the second steel beam 9 respectively; a floor slab 10, the floor slab 10 being disposed between the steel plate wall 4 and the second steel beam 9; a connecting end plate 6, the connecting end plate 6 being disposed through the floor slab 10 along the first direction, the connecting end plate 6 extending along a direction close to the steel plate wall 4, the second steel beam 9 being connected to one end of the connecting end plate 6, and the other end of the connecting end plate 6 being connected to the second steel beam 9. The steel plate wall 4 is connected to the steel plate wall 4; or, a concrete shear wall 13 is connected to the steel plate wall 4, the concrete shear wall 13 is provided with embedded plates 14, the embedded plates 14 are spaced apart at opposite tops of the concrete shear wall 13, and backfill steel plates 15 are provided between adjacent embedded plates 14, the spacing between the backfill steel plates 15 and adjacent embedded plates 14 is adapted; it also includes a connection step between the steel plate wall 4 and the first steel beam 5: a first connecting plate 1 is provided on the upper part of the steel plate wall 4, the first connecting plate 1 and the first steel beam flange 2 of the first steel beam 5 are provided with bolt holes, and a first connector 3 is used to pass through the bolt holes to achieve a tight connection between the steel plate wall 4 and the first steel beam 5. In response to the closed section characteristics of the integrated steel plate wall 4, the problem of rapid connection of closed sections that cannot be achieved by traditional high-strength bolts is successfully solved by the bolt hole cooperation between the first connecting plate 1 and the flange 2 of the first steel beam, combined with the use of the first connecting piece 3. This eliminates the need for complex welding operations on site, simplifies the installation process, and greatly improves the connection efficiency between the steel plate wall 4 and the upper steel beam. At the same time, the fastening connection method ensures the reliability of the connection and the structural stability of the two.
[0029] The connection steps between the steel plate wall 4, the floor slab 10, and the second steel beam 9 are as follows: Before the floor slab 10 is poured, the connecting end plate 6 is welded to the second steel beam flange 7 of the second steel beam 9, so that the connecting end plate 6 passes through the floor slab 10 and extends to the second connecting plate 17 of the steel plate wall 4. After the reinforcing bars of the floor slab 10 pass through the connecting end plate 6, the floor slab 10 is poured. After the floor slab 10 is formed, the second connector 8 passes through the first bolt hole 12 of the connecting end plate 6 and the second connecting plate 17 to achieve a tight connection between the steel plate wall 4, the floor slab 10, and the second steel beam 9. By pre-welding the connecting end plate 6 and reserving the round hole 11, the normal arrangement of the reinforcing steel of the floor slab 10 and the pouring quality of the floor slab 10 are ensured, and the precise connection between the connecting end plate 6 and the steel plate wall 4 and the second steel beam 9 is achieved. After the floor slab 10 is formed, it is fastened by the second connector 8. The process is simple and smooth, which reduces the interference of cross construction on site, shortens the construction period, and reduces the construction cost. At the same time, it realizes the integrated fastening of the steel plate wall 4, the floor slab 10 and the second steel beam 9, and improves the overall structural performance.
[0030] The connection steps between the steel plate wall 4 and the concrete shear wall 13 are as follows: When the concrete shear wall 13 is poured, embedded plates 14 are set at intervals on its top with gaps reserved. A vibrator is used to pass through the gaps to vibrate the concrete inside the concrete shear wall 13. After vibration, the backfill steel plate 15 is welded between the adjacent embedded plates 14 to form a third connection, and the backfill steel plate 15 and the embedded plate 14 are kept flush. The steel plate wall 4 and the concrete shear wall 13 are fastened by passing the second connecting piece 8 through the second bolt hole 19 of the second connecting plate 17 of the steel plate wall 4 through the third connecting plate 18 on the embedded plate 14. First, the embedded plates 14 are set at intervals, which effectively solves the vibration problem during the pouring of concrete shear wall 13 and ensures the density of concrete and structural strength. Then, the steel plate 15 is backfilled to form a complete load-bearing surface, which ensures the force transmission foundation of the connection. Finally, the second connector 8 is used to achieve a tight connection, which not only ensures the reliability of the connection between steel plate wall 4 and concrete shear wall 13 and the effectiveness of force transmission, but also reduces the amount of on-site welding work, improves installation efficiency, and takes into account both construction quality and construction convenience.
[0031] The above three steps clarify the complete connection process of the integrated steel plate wall 4, systematically covering the key connection links with the first steel beam 5, floor slab 10, second steel beam 9, and concrete shear wall 13. This provides clear and standardized methodological guidance for construction, ensuring that the connection operation proceeds in an orderly manner, avoiding construction errors or connection failures caused by chaotic processes, and helping to carry out standardized and efficient engineering construction.
[0032] The integrated steel plate wall 4 in this embodiment is not a traditional single steel plate structure, but an integrated earthquake-resistant, thermal insulation and sound insulation wall. Its core component, the steel plate wall 4, is mainly composed of non-buckling corrugated steel plate, with cement fiberboard (CAA) and thermal insulation and sound insulation materials on both sides. It has both the structural function of high lateral stiffness and the thermal insulation and sound insulation performance required for building envelope, thus solving the defect of traditional steel plate wall 4 which only focuses on structural function and lacks enclosure function.
[0033] The first steel beam 5 serves as the upper load-bearing component. Its lower flange and the upper end plate of the steel plate wall 4 are both provided with matching bolt holes. The fastening connection is achieved by using one-way bolts, which solves the problem that traditional high-strength bolts cannot be installed from both sides after the steel plate wall 4 is closed due to the composite CCA plates on both sides. The bolts can be tightened from only one side, which greatly simplifies the construction process of the upper connection.
[0034] The connection between the second steel beam 9 and the steel plate wall 4 is achieved by the connection end plate 6 penetrating through the floor slab 10. In this embodiment, when welding the connection end plate 6, it is necessary to ensure its perpendicularity to the upper flange of the second steel beam 9, and the length of the end plate extending to one side of the steel plate wall 4 must match the width of the lower connection plate of the steel plate wall 4 to ensure that the two can fit together completely when bolted later, and to avoid uneven stress caused by the gap between the fitting.
[0035] By clarifying the composition and connection relationships of the integrated steel plate wall 4, the problems of difficult connection and compatibility and dispersed stress system of traditional integrated steel plate wall 4 in steel structure buildings are solved, providing key support for the overall structural stability and efficient construction. Addressing the problem of unilateral stress imbalance that easily occurs when connecting the traditional steel plate wall 4 to the steel beams, the first and second steel beams 9 are respectively set on both sides of the steel plate wall 4 along the first direction and are both connected to the steel plate wall 4, forming a symmetrical double-sided support structure. This allows the horizontal or vertical loads borne by the steel plate wall 4 to be evenly transferred to the steel beams on both sides, avoiding local deformation of the steel plate wall 4 and stress overload of the steel beams caused by unilateral stress concentration, significantly improving the stress performance of the upper steel structure, and matching the high requirements of steel structure buildings for overall lateral stiffness and seismic resistance. In the connection between the steel plate wall 4 and the floor slab 10, the connecting end plate 6 penetrates the floor slab 10 and extends towards the steel plate wall 4. The end plate penetrating the floor slab 10 forms a rigid connection between the floor slab 10 and the steel plate wall 4, ensuring that the floor load is transferred to the floor slab through the end plate. The steel plate wall 4 and the second steel beam 9 prevent the floor slab 10 from cracking due to insufficient support. Regarding the vibration problem of the connection with the concrete shear wall 13, the traditional embedded plate 14 is prone to obstructing vibration due to the small gap, resulting in insufficient concrete density. However, the gap formed by the spacer embedded plate 14 can accommodate the vibrator, ensuring the quality of concrete pouring. The subsequent backfill steel plate 15 can fill the gap, so that the embedded plate 14 forms a continuous force-bearing surface, avoiding the break point of force transmission, ensuring that the load is evenly transferred to the shear wall, and preventing local stress concentration from causing structural damage.
[0036] Specifically, the connecting end plate 6 has a circular hole 11 and a first bolt hole 12. The circular hole 11 is used for the reinforcing bars of the floor slab 10 to pass through, and the first bolt hole 12 is suitable for the second connector 8 to pass through. The circular hole 11 of the connecting end plate 6 allows the reinforcing bars of the floor slab 10 to pass through smoothly, avoiding the connecting end plate 6 from obstructing the normal arrangement of the reinforcing bars of the floor slab 10, and ensuring the structural integrity and load-bearing performance of the floor slab 10. The first bolt hole 12 provides a precise installation channel for the second connector 8, ensuring that the steel plate wall 4, the floor slab 10, and the second steel beam 9 can be firmly and securely fastened through the connector. This takes into account both the continuity of the construction of the floor slab 10 and the reliability and stability of the connection between the three, thus improving the practical value of the connection structure.
[0037] In one embodiment, the gap between the embedded plates 14 is larger than the diameter of the vibrator to meet the requirement of inserting the vibrator into the concrete shear wall 13 for vibration. The larger gap between the embedded plates 14 allows the vibrator to be easily inserted into the concrete shear wall 13 for thorough vibration, completely solving the problem of insufficient concrete compaction caused by the small gap between the traditional embedded plates 14. This effectively avoids problems such as insufficient strength and reduced load-bearing capacity caused by insufficient concrete vibration, providing a crucial guarantee for the structural quality and subsequent connection reliability of the concrete shear wall 13.
[0038] The gap is placed in the middle of the steel plate wall 4 because the shear force borne by the steel plate wall 4 is mainly transferred to the concrete shear wall 13 through the middle area. If the gap is placed at the edge, the force at the edge of the steel plate wall 4 may not be effectively transferred. However, after the backfill steel plate 15 in the middle is welded, it can form a stable force with the embedded plates 14 on both sides, ensuring that the shear force of the steel plate wall 4 is evenly transferred to the top of the entire shear wall, avoiding local stress concentration that could cause the embedded plates 14 to tear.
[0039] In one embodiment, the backfill steel plate 15 is connected to the adjacent embedded plate 14 by welding, the backfill steel plate 15 and the embedded plate 14 are kept on the same plane, and the backfill steel plate 15 is used to fill the gap between the embedded plates 14.
[0040] The backfill steel plate 15 is connected to the adjacent embedded plate 14 by welding. This not only tightly fills the gap between the embedded plates 14, but also keeps them on the same plane. This makes the originally separate embedded plates 14 form a complete and continuous load-bearing surface, ensuring uniform force transmission when the steel plate wall 4 is connected to the concrete shear wall 13. This significantly improves the shear bearing capacity and overall load-bearing performance of the connection. At the same time, the welding connection method is stable and reliable, avoiding weak points in the gaps.
[0041] In one embodiment, a third connecting plate 18 is provided on the embedded plate 14, and a second connecting plate 17 is provided on the side of the steel plate wall 4 near the third connecting plate 18. The third connecting plate 18 and the second connecting plate 17 are provided with second bolt holes 19, and the second connecting piece 8 is connected to the second bolt holes 19.
[0042] If the steel plate wall 4 is designed to have a large shear bearing capacity, a double shear mechanism is adopted. Two parallel third connecting plates 18 are welded on the embedded plate 14, with the distance between the two plates being the same as the thickness of the second connecting plate 17. This allows the second connecting plate 17 to be embedded between the two third connecting plates 18. After the bolt passes through the second bolt holes 19 of the three plates, a double shear surface is formed. The shear force on the bolt is borne by both surfaces, which can significantly improve the shear ultimate bearing capacity of the connection. If the steel plate wall 4 is designed to have a small shear bearing capacity, a single shear mechanism is adopted. Only one third connecting plate 18 is welded on the embedded plate 14. After it is attached to the second connecting plate 17, it is connected by bolts to form a single shear surface. This satisfies the stress requirements while reducing the amount of material used and the amount of welding work.
[0043] The cooperation between the third connecting plate 18 and the second connecting plate 17, as well as the corresponding second bolt hole 19, provides a precise installation fit point for the second connector 8, enabling precise alignment and firm connection between the steel plate wall 4 and the embedded plate 14, forming a clear and reliable force transmission path. This ensures that the load borne by the steel plate wall 4 can be effectively transferred to the concrete shear wall 13, avoiding poor force transmission or stress concentration at the connection point, and significantly improving the stability and load-bearing capacity of the connection.
[0044] In one embodiment, the third connecting plate 18 is provided with stiffening ribs 20. Providing stiffening ribs 20 on the third connecting plate 18 can significantly improve the overall stiffness and deformation resistance of the connecting plate, effectively preventing buckling, excessive deformation, or damage when the connecting plate is subjected to shear loads, further strengthening the stress stability and shear resistance of the connection between the steel plate wall 4 and the concrete shear wall 13. This allows for flexible adaptation to scenarios with different shear bearing capacity requirements, extending the service life of the connection structure.
