Description

Technical Field

[0001] This application relates to the field of construction technology for transfer layers, and in particular to a steel plate wall for transfer layers. Background Technology

[0002] With the diversification of functions in high-rise buildings, the differences in building functions between different floors lead to differences in building structures. Therefore, it is necessary to set up transfer floors between floors with different structures to connect and transition between adjacent floors with different structures. The transfer floor is usually composed of frame columns, transfer beams and steel plate shear walls. Since the transfer floor bears the huge load of the superstructure and will generate complex stress concentration phenomena when transferring forces, the connection strength, positioning accuracy and overall stability of the three directly determine the structural safety of the transfer floor and even the entire building.

[0003] Currently, during the construction of transfer floors, transfer beams and steel plate walls are typically connected by direct welding, with the bottom surface of the transfer beam welded to the top surface of the steel plate wall. However, this single welding method results in weak connection capacity at stress points, a relatively simple force transmission path, insufficient shear bearing capacity at joints, and a lack of effective local reinforcement around the welded joints. Under heavy loads, stress concentration can easily occur, leading to weld cracking or structural deformation. Furthermore, existing transfer beams and steel plate walls contain a large amount of reinforcing steel, but the path of the reinforcing steel at the connection joints has not been properly planned, requiring the steel to be cut during construction, which severely weakens the structural integrity of the transfer beam. Summary of the Invention

[0004] In order to improve the shear bearing capacity and overall structural strength of the connection node between the transfer layer steel plate wall and the transfer beam, and to rationally plan the reinforcement path, this application provides a transfer layer steel plate wall.

[0005] The technical solution for a transfer layer steel plate wall provided in this application is as follows: A transfer layer steel plate wall includes frame columns, a shear wall between two adjacent frame columns, a transfer beam on the top of the shear wall, the transfer beam being stably supported on the top of the shear wall, a connecting component on the shear wall, the top surface of the connecting component abutting against the transfer beam, a first through hole in the shear wall, and a second through hole in the connecting component, both the first and second through holes being horizontally oriented and connected, the transfer beam including stirrups passing through the first and second through holes.

[0006] By adopting the above technical solution, the transfer beam is stably erected on top of the shear wall, allowing the load of the superstructure to be directly transferred to the shear wall. A connecting component is installed on top of the shear wall, and a first through hole is made in the shear wall, while a second through hole is made in the connecting component. This allows the stirrups of the transfer beam to pass through the first and second through holes for installation and binding, thereby connecting the transfer beam, connecting component, and shear wall into an integrated load-bearing system. At the same time, the top surface of the connecting component abuts against the transfer beam, and the side wall is connected to the shear wall, achieving a double-sided fit for force transmission. This significantly improves the fit, connection stiffness, and overall structural integrity of the connection node between the transfer beam and the shear wall, significantly enhances the shear and compressive bearing capacity of the node, and ensures the structural stability of the core connection node of the transfer layer.

[0007] Optionally, the transfer beam includes steel sections and longitudinal reinforcement. The steel section has an I-shaped cross-section, and the bottom surface of the lower flange of the steel section is connected to the upper surface of the shear wall. The longitudinal reinforcement is arranged along the length of the steel section, and the stirrups are arranged around the longitudinal reinforcement to bind the steel section and the longitudinal reinforcement.

[0008] By adopting the above technical solution, the transfer beam uses a combination structure of I-shaped steel and longitudinal reinforcement. The bottom surface of the lower flange of the I-shaped steel can fully contact the upper surface of the shear wall, providing a stable and sufficient docking base for the connection between the transfer beam and the shear wall. This allows for direct large-area welding and fixing, effectively increasing the contact area and welding work surface at the beam-column connection points, and significantly improving the connection strength between the transfer beam and the shear wall. At the same time, the I-shaped steel itself has excellent bending and shear resistance, which can effectively bear and distribute the load of the superstructure, improve the overall stress performance of the transfer beam, significantly improve the connection strength and bending stiffness between the transfer beam and the shear wall, enhance the overall stress performance of the transfer beam itself, and ensure that the superstructure load is effectively transferred to the shear wall through the transfer beam.

[0009] Optionally, the connecting assembly includes a reinforcing plate, which is arranged horizontally and connected to the side wall of the shear wall. The second through hole is formed on the reinforcing plate and penetrates the reinforcing plate vertically in the horizontal direction. The top surface of the reinforcing plate abuts against the bottom surface of the lower flange of the steel section.

[0010] By adopting the above technical solution, the connecting component includes a reinforcing plate arranged in the horizontal direction. The sidewall of the reinforcing plate is connected to the shear wall, and the top surface abuts against the bottom surface of the lower flange of the steel section. The second through hole is opened on the reinforcing plate and penetrates the reinforcing plate vertically in the horizontal direction. The reinforcing plate provides a foundation for opening the second through hole. At the same time, through its connection with the shear wall and its supporting effect on the steel section above it, an effective force transmission path is formed in the vertical direction, which indirectly increases the connection area between the shear wall and the transfer beam, avoids damage to the connection node area due to excessive local bearing pressure, and enhances the integrity and load-bearing capacity of the node.

[0011] Optionally, the shear wall is provided with transverse stiffening plates and longitudinal stiffening plates, both of which are perpendicular to the shear wall and orthogonally arranged.

[0012] By adopting the above technical solution, transverse stiffening plates and longitudinal stiffening plates are orthogonally arranged on the surface of the shear wall. The bidirectional vertical stiffening structure can form a comprehensive reinforcement and constraint on the shear wall from both transverse and longitudinal dimensions, effectively improving the planar stiffness, overall strength and deformation resistance of the steel plate shear wall itself. It can effectively offset the complex loads and shear stresses transmitted by the transfer layer, avoid buckling, deformation and cracking of the shear wall under long-term heavy load and complex stress conditions, and ensure the load-bearing stability of the main structure of the shear wall.

[0013] Optionally, the reinforcing plate is provided with a reinforcing plate, the reinforcing plate is perpendicular to the reinforcing plate, and the reinforcing plate is attached to the lower end face of the lower flange of the steel section. The reinforcing plate and the second through hole are staggered on the reinforcing plate.

[0014] By adopting the above technical solution, a reinforcing plate is vertically installed on the reinforcing plate. The reinforcing plate is in contact with the lower end face of the lower flange of the steel section, forming a multi-point support and reinforcement for the lower flange of the steel section. Together with the reinforcing plate, it forms a three-dimensional reinforcing structure, which further increases the local bearing area at the connection node, effectively strengthens the stiffness of the connection node between the reinforcing plate and the transfer beam steel section, significantly enhances the local stiffness and punching shear resistance of the node area, effectively alleviates the stress concentration phenomenon during the load transfer process, and prevents the weld and connection area from cracking or being damaged under complex stress conditions.

[0015] Optionally, a plurality of studs are provided on the side of the shear wall away from the transverse stiffening plate and the longitudinal stiffening plate. The plurality of studs are arranged in a matrix at intervals on the same side of the shear wall, and each stud is perpendicular to the wall surface of the shear wall.

[0016] By adopting the above technical solution, the matrix-arranged studs on the shear wall surface can serve as precise positioning and connection points for transverse and longitudinal reinforcement bars, standardizing the spacing and path of the reinforcement bars, avoiding problems such as messy reinforcement bar arrangement and positioning deviation. At the same time, the studs are vertically fixed to the shear wall surface, which can effectively anchor and combine with the subsequently laid reinforcement system, realizing a reliable connection between the reinforcement bars and the shear wall, providing basic anchoring support for the formation of the overall reinforcement skeleton system, and ensuring the layout accuracy and connection stability of the reinforcement structure.

[0017] Optionally, a third through hole is provided in the shear wall, the axis of the third through hole is perpendicular to the shear wall, and a main reinforcement bar is inserted into the third through hole.

[0018] By adopting the above technical solution, a third through hole is opened in the shear wall along the horizontal direction. The axis of the third through hole is perpendicular to the shear wall, allowing the main reinforcement to pass through the third through hole. The third through hole provides a reasonable path for the horizontal main reinforcement, enabling the main reinforcement to penetrate the shear wall and maintain continuity. This avoids the problem of structural integrity damage and load-bearing capacity reduction caused by arbitrary cutting of the main reinforcement during construction, ensuring the continuity of force transmission of the horizontal main reinforcement and the integrity of the structure. At the same time, it realizes the effective connection between the steel reinforcement cage and the steel plate wall.

[0019] Optionally, a reinforcing sleeve is connected to the shear wall, the reinforcing sleeve being coaxially arranged with the third through hole and communicating with the third through hole.

[0020] By adopting the above technical solution, a reinforcing sleeve is connected to the shear wall, which is coaxially arranged and connected to the third perforation. The reinforcing sleeve provides local reinforcement to the area around the third perforation of the shear wall, effectively compensating for the weakening of the shear wall section caused by the opening, preventing stress concentration at the opening from causing the steel plate to tear or buckle locally, and ensuring the structural integrity and load-bearing capacity of the shear wall after the opening.

[0021] Optionally, it also includes transverse and longitudinal reinforcing bars, wherein the transverse reinforcing bars are arranged horizontally and pass between adjacent rows of studs, and the longitudinal reinforcing bars are arranged vertically and pass between adjacent columns of studs, and both the transverse and longitudinal reinforcing bars can be tied to the studs.

[0022] By adopting the above technical solution, the transverse reinforcement passes through the space between two adjacent rows of studs in the horizontal direction, and the longitudinal reinforcement passes through the space between two adjacent columns of studs in the vertical direction. Both the transverse and longitudinal reinforcements can be tied with the studs. Under the positioning and constraint of the studs, the transverse and longitudinal reinforcements form a two-way steel mesh on one side of the shear wall, which together with the studs constitutes a complete composite skeleton structure. This effectively improves the synergistic working performance and overall flexural bearing capacity between the shear wall and the post-cast concrete, and enhances the structural integrity of the shear wall under complex stress conditions.

[0023] Optionally, the shear wall is provided with L-shaped connecting bars, one side of which is attached to and welded to the shear wall, and the other side is set along the length of the main bar and overlaps with the main bar.

[0024] By adopting the above technical solution, L-shaped connecting bars are set in the shear wall. This addresses the situation where it is unavoidable to perforate the main reinforcement bars during construction and cut them off. The L-shaped connecting bars are welded and fixed to the shear wall at one end and overlapped with the cut main reinforcement bars at the other end. This achieves a reliable anchorage connection between the cut main reinforcement bars and the shear wall, effectively preventing the problems of fracture under stress after the main reinforcement bars are cut, loss of structural integrity, and significant reduction in strength. It completely transfers the stress of the main reinforcement bars, ensures the continuity and load-bearing capacity of the main reinforcement system, minimizes the impact of construction defects on the overall structural strength, improves structural tolerance and construction adaptability, and ensures the safety of the transfer layer structure.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting a connecting component at the top of the shear wall, and cooperating with the first through hole on the shear wall and the second through hole on the connecting component, the stirrups of the transfer beam can pass through the two connected through holes to complete the layout and binding, connecting the transfer beam, the connecting component and the shear wall into an integral force-bearing system. At the same time, the top surface of the connecting component abuts against the transfer beam and the side wall connects to the shear wall to form a double-sided fitting force transmission structure, which significantly improves the shear bearing capacity of the connection node between the transfer beam and the shear wall and the overall structural stability. 2. The transfer beam adopts a combination structure of I-shaped steel with longitudinal reinforcement and stirrups. The bottom surface of the lower flange of the I-shaped steel and the upper surface of the shear wall form a stable and sufficient butt base, which can realize large-area welding and fixing, effectively increasing the contact area and welding work surface of the connection point, greatly improving the connection firmness and bending stiffness between the transfer beam and the shear wall, and ensuring that the upper load is effectively transferred to the shear wall through the transfer beam; 3. Orthogonally set transverse stiffening plates and longitudinal stiffening plates on the surface of the shear wall to form a comprehensive reinforcement and constraint on the shear wall from both transverse and longitudinal dimensions. This effectively improves the planar stiffness, overall strength and deformation resistance of the steel plate shear wall itself, and can resist the complex loads and shear stresses transmitted by the transfer layer. This prevents the shear wall from buckling or deforming under long-term heavy load conditions and ensures the load-bearing stability of the main structure of the shear wall. 4. Several shear studs perpendicular to the wall surface are arranged in a matrix on the shear wall surface to provide precise positioning and connection points for the horizontal and vertical reinforcement bars. Under the positioning constraint of the shear studs, the horizontal and vertical reinforcement bars form a two-way steel mesh on one side of the shear wall surface, which together with the shear studs constitutes a complete composite skeleton structure, effectively improving the synergistic working performance between the shear wall and the post-cast concrete and the overall bending bearing capacity. 5. L-shaped connecting bars are installed on the shear wall. When the main reinforcement cannot pass through the third through hole during construction and must be cut off, one end of the L-shaped connecting bar is welded and fixed to the shear wall, and the other end is lapped with the cut main reinforcement. This achieves a reliable anchorage connection between the cut main reinforcement and the shear wall, effectively preventing the main reinforcement from breaking under stress after cutting and the problem of structural integrity loss. It ensures the continuity and load-bearing capacity of the main reinforcement system and minimizes the impact of construction defects on the overall structural strength. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0034] This application discloses a conversion layer steel plate wall.

[0035] like Figures 1 to 3A type of steel plate wall for a transfer layer includes frame columns 1 and shear walls 2. Several frame columns 1 are provided and spaced vertically within the transfer layer. Shear walls 2 are provided between two adjacent frame columns 1. Shear walls 2 have a rectangular plate structure and are arranged vertically. A transfer beam 3 is provided on the top end face of the shear wall 2. The top of the transfer beam 3 is connected to the upper structure to transfer the load of the upper structure.

[0036] The transfer beam 3 includes a steel section 31, longitudinal reinforcement 32, and stirrups 33. The cross-sectional profile of the steel section 31 is I-shaped. The top surface of the upper flange and the bottom surface of the lower flange of the steel section 31 are both horizontal and flat. The bottom surface of the lower flange of the steel section 31 abuts against the upper end face of the shear wall 2 and is stably erected on the upper end face of the shear wall 2. The upper end face of the shear wall 2 is in close contact with the lower end face of the lower flange of the steel section 31. Several longitudinal reinforcements 32 are provided. Several longitudinal reinforcements 32 are laid in groups along the length direction of the steel section 31 and arranged in a direction parallel to the length direction of the steel section 31. Stirrups 33 are set around the longitudinal reinforcements 32 and the steel section 31 and are set around the longitudinal reinforcements 32 and the steel section 31. Each stirrup 33 is set around the outer contour of the steel section 31 and the longitudinal reinforcement 32 to bind the steel section 31 and the longitudinal reinforcement 32 as a whole.

[0037] Near the top of the shear wall 2, several first through holes 21 are formed horizontally. The first through holes 21 are of the same size, and the axes of all the first through holes 21 are on the same horizontal line. The axes of the first through holes 21 penetrate the surface of the shear wall 2 vertically along the horizontal direction. Two sets of connecting components 4 are provided on the upper sidewall of the shear wall 2. The two sets of connecting components 4 are located on both sides of the shear wall 2. The connecting components 4 include reinforcing plates 41. The reinforcing plates 41 are arranged horizontally, and one sidewall of the reinforcing plates is attached to the shear wall 2 and connected to the sidewall of the shear wall 2 by welding. like Figures 3 to 5 The top end face of the reinforcing plate 41 is closely fitted with the bottom surface of the lower flange of the I-shaped steel 31, supporting the steel 31 in the vertical direction. The reinforcing plate 41 has several second through holes 411 with the same specifications as the first through hole 21. The number of second through holes 411 is equal to that of the first through hole 21 and they correspond one-to-one. The axis of the second through hole 411 coincides with the axis of the first through hole 21. They are all set in the horizontal direction and penetrate the reinforcing plate 41 vertically in the horizontal direction. The openings of the first through hole 21 and the second through hole 411 are connected to each other to form a connecting channel for the stirrups 33 of the transfer beam 3 to pass through. The stirrups 33 pass through the first through hole 21 and the second through hole 411 in sequence and surround the steel 31 and the longitudinal reinforcement 32, forming a physical through constraint between the shear wall 2 and the transfer beam 3.

[0038] A reinforcing plate 412 is connected to the reinforcing plate 41. The surface of the reinforcing plate 412 is perpendicular to the surface of the reinforcing plate 41. The top edge of the reinforcing plate 412 is in the same horizontal plane as the top surface of the reinforcing plate 41 and is in contact with the lower end face of the lower flange of the steel section 31. The reinforcing plate 412 and the reinforcing plate 41 are connected and fixed by double-sided welding. The second through hole 411 and the reinforcing plate 412 are arranged alternately on the surface of the reinforcing plate 41, so that the contact surface of the reinforcing plate 412 avoids the channel path of the second through hole 411.

[0039] like Figure 3 and Figure 6 One side of the shear wall 2 is provided with a transverse stiffening plate 22 and a longitudinal stiffening plate 23. The transverse stiffening plate 22 is set in the horizontal direction, and the longitudinal stiffening plate 23 is set in the vertical direction. The surfaces of the transverse stiffening plate 22 and the longitudinal stiffening plate 23 are perpendicular to each other. The transverse stiffening plate 22 and the longitudinal stiffening plate 23 intersect each other on the surface of the shear wall 2 and are welded and fixed at the intersection point to form an orthogonal grid structure. The length of the transverse stiffening plate 22 is equal to the length of the shear wall 2, and the length of the longitudinal stiffening plate 23 is equal to the height of the shear wall 2.

[0040] like Figure 1 and Figure 6 A number of studs 24 are provided on the side of the shear wall 2 away from the transverse stiffening plate 22 and the longitudinal stiffening plate 23. The studs 24 are arranged in a matrix at equal intervals on one side of the shear wall 2. Each stud 24 is set perpendicular to the wall surface of the shear wall 2. Its root end is welded and fixed to the panel of the shear wall 2, and its rod extends outward from the wall. The cross-sectional area of ​​the head of the stud 24 is larger than the cross-sectional area of ​​the rod of the stud 24. There are gaps between adjacent rows of studs 24 and between adjacent columns of studs 24. A transverse steel bar 25 is inserted between adjacent rows of studs 24, and a longitudinal steel bar 26 is inserted between adjacent columns of studs 24. The transverse steel bar 25 and the longitudinal steel bar 26 are tied and fixed to the rod of the stud 24, so that the transverse steel bar 25 and the longitudinal steel bar 26 can form a complete grid steel structure on the surface of the shear wall 2.

[0041] A third through hole 27 is also provided on the shear wall 2. The third through hole 27 penetrates the shear wall 2 vertically in the horizontal direction. The shear wall 2 is provided with main reinforcement 29, which penetrates the third through hole 27 along the axis of the third through hole 27. A cylindrical reinforcing sleeve 28 is connected to the shear wall 2. The reinforcing sleeve 28 is arranged around the hole of the third through hole 27, and the axis of the reinforcing sleeve 28 coincides with the axis of the third through hole 27. The inner hole of the reinforcing sleeve 28 is connected to the inner hole of the third through hole 27. The sleeve wall is attached to and surrounds the edge of the hole wall of the third through hole 27 to reinforce the opening of the shear wall 2. The main reinforcement 29 of the transfer beam 3 passes through the inner hole of the reinforcing sleeve 28.

[0042] L-shaped connecting bars 291 are provided on the side wall of shear wall 2. One end of the L-shaped connecting bar 291 is close to the surface of shear wall 2 and is fixed to shear wall 2 by welding. The other straight end extends horizontally, and its extension direction is parallel to the direction of the main bar 29 and adjacent to the cut end of the main bar 29. The two are overlapped and fixed, so that the stress of the main bar 29 can be transferred to shear wall 2 through the L-shaped connecting bar 291.

[0043] The implementation principle of this application embodiment is as follows: During the construction of the transfer layer, the shear wall 2 is first hoisted and transported between the two side columns 1 to complete the positioning welding of the shear wall 2 and the side columns 1. Then, the transfer beam 3 is hoisted to the top of the shear wall 2, so that the bottom surface of the lower flange of the steel section 31 is in contact with the upper end surface of the shear wall 2 and the two are welded and fixed. Reinforcing plates 41 are welded on both sides of the top of the shear wall 2, so that the side wall of the reinforcing plate 41 is in contact with the side wall of the shear wall 2 and the top surface is in contact with the bottom surface of the lower flange of the steel section 31. Then, a reinforcing plate 412 is vertically welded to the outside of the reinforcing plate 41. The top of the reinforcing plate 412 is in contact with the lower end surface of the lower flange of the steel section 31 and is welded and fixed. The contact area between the shear wall 2 and the steel section 31 is increased by the reinforcing plate 41 and the reinforcing plate 412, and the lower end surface of the lower flange of the steel section 31 is supported.

[0044] Next, the reinforcement binding operation is carried out. During binding, the main reinforcement 29 passes through the third through hole 27 on the shear wall 2 and the inner hole of the reinforcing sleeve 28 in the horizontal direction to complete the insertion and positioning of the main reinforcement 29. The stirrups 33 of the transfer beam 3 are wrapped around the periphery of the longitudinal reinforcement 32 and the steel section 31 according to the preset direction, and the stirrups 33 pass through the first through hole 21 opened on the shear wall 2 and the second through hole 411 opened on the reinforcing plate 41 in sequence, so that the stirrups 33 pass through the shear wall 2 and the transfer beam 3 in the horizontal direction. On the side of the shear wall 2 away from the horizontal stiffening plate 22 and the vertical stiffening plate, the horizontal reinforcement 25 passes through the gap between two adjacent rows of studs 24, and the longitudinal reinforcement 26 passes through the gap between two adjacent rows of studs 24. After the horizontal and longitudinal reinforcements are arranged in an alternating manner, the horizontal reinforcement 25 and the longitudinal reinforcement 26 are tied and fixed to the rod of the stud 24 at the intersection point to form a two-way reinforcement grid skeleton attached to the array of studs 24.

[0045] During the above-mentioned reinforcement positioning process, when the main reinforcement 29 cannot be inserted into the third through hole 27 due to construction errors, the main reinforcement 29 is cut off, and an L-shaped connecting reinforcement 291 is welded to the shear wall 2 near the cut end of the main reinforcement 29. One end of the L-shaped connecting reinforcement 291 is welded to the shear wall 2, and the other end extends along the direction of the main reinforcement 29 and overlaps and fixes with the cut end of the main reinforcement 29 to make up for the connection gap caused by the cut of the main reinforcement 29.

[0046] After completing the welding of transfer beam 3, welding of connecting components 4, installation of stirrups 33, installation of main reinforcement 29, binding of transverse and longitudinal steel mesh, and lap splicing of L-shaped connecting reinforcement 291, all the steel reinforcement systems inside the node have been positioned and anchored to shear wall 2 and transfer beam 3. Subsequently, formwork is erected on both sides of shear wall 2 and concrete is poured, so that the concrete fills the space between steel section 31, longitudinal reinforcement 32, transverse and longitudinal reinforcement 26, studs 24 and reinforcing plate 412. After the concrete solidifies, shear wall 2, transfer beam 3, connecting components 4 and steel mesh form an integral combined load-bearing structure.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
