Description

Technical Field

[0001] This invention belongs to the field of modular concrete building technology, and particularly relates to a connection structure between the wall formwork on both sides of a shear wall and the shear wall itself. Background Technology

[0002] Prefabricated shear walls can be divided into two types: composite shear walls and precast solid walls. When prefabricated technology is upgraded to modular buildings, composite shear walls are more suitable for interior walls than precast solid walls.

[0003] Modular construction refers to the process of breaking down a single building into modules based on its spatial structure, unit type, and functional zoning. These modules are then prefabricated in a factory, transported to the construction site, and installed to form a building entity that meets safety, reliability, and related functional requirements. Compared to traditional construction methods, modular integrated construction offers advantages such as high construction efficiency, resource conservation, environmental friendliness, and civilized construction practices.

[0004] Modular buildings have load-bearing walls and other main structures between adjacent modules. Composite shear wall structures have the characteristics of good overall performance, high stiffness, and small lateral deformation under horizontal loads, and are widely used in load-bearing walls. The modules of modular buildings use concrete wall panels as formwork for on-site concrete pouring to create composite shear walls, which greatly reduces the time for on-site formwork and interior decoration, and minimizes the impact on surrounding residents.

[0005] However, patent CN218522010U discloses a prefabricated wall structure in integrated buildings. The prefabricated wall panel, which serves as a formwork for pouring concrete, is only used as a formwork and is not part of the shear wall. It does not participate in the structural stress, which wastes materials, occupies the usable indoor area, and the steel bars of the poured shear wall need to be tied on site, which limits the improvement of production efficiency. Summary of the Invention

[0006] (a) Technical problems to be solved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a connection structure between the wall formwork on both sides of a shear wall and a shear wall, thereby solving the technical problems that the precast wall panels do not participate in the structural stress, encroach on the usable indoor area, and the steel bars of the cast shear wall need to be tied on site.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the main technical solutions adopted by the present invention include:

[0010] On one hand, embodiments of the present invention provide a connection structure for connecting wall formworks on both sides of a shear wall, including a first connecting component and a second connecting component. The first connecting component includes a first steel plate and a first connector. The first steel plate includes a first embedded end, which is used to be embedded in a first precast wall formwork forming the shear wall. The first connector is fixed to the end of the first steel plate away from the first embedded end. The second connecting component includes a second steel plate and a second connector. The second steel plate includes a second embedded end, which is used to be embedded in a second precast wall formwork forming the shear wall. The second connector is fixed to the end of the second steel plate away from the second embedded end. The first connecting component and the second connecting component are connected by fixing the first connector and the second connector.

[0011] Furthermore, the first steel plate is at the same height as the first precast wall formwork, and the second steel plate is at the same height as the second precast wall formwork. Both the first and second steel plates have multiple vertical through holes to accommodate the horizontal reinforcement of the beams connected to the shear wall.

[0012] Furthermore, both the first and second steel plates have L-shaped cross-sections. The first steel plate has a horizontal cross-section and a partially vertical cross-section forming a first embedded end. Multiple first grooved slide rails are fixed to the vertical cross-section of the first steel plate, and these multiple first grooved slide rails are arranged along the height direction of the first precast wall formwork. The first grooved slide rails are first connecting parts. The second steel plate has a horizontal cross-section and a partially vertical cross-section forming a second embedded end. A third steel plate is welded to the vertical cross-section of the second steel plate. The third steel plate has the same height as the second steel plate, and the plane of the third steel plate is perpendicular to the plane of the vertical cross-section of the second steel plate. The third steel plate is a second connecting part. The third steel plate is locked in place with all the first grooved slide rails.

[0013] Furthermore, the inner sides of the upper and lower openings of the first groove slide rail are both provided with a first chamfer to form a trumpet shape.

[0014] Furthermore, first connecting plates extend from both sides of the first grooved slide rail, and both first connecting plates are welded to the vertical section of the first steel plate.

[0015] Furthermore, the first connecting component and the second connecting component have the same structure and are symmetrically arranged about the center of the shear wall. Both the first and second steel plates include an integrally formed vertical plate and horizontal plates connected to both ends of the vertical plate. The two horizontal plates extend in opposite directions. Multiple second-channel slide rails are welded to the vertical plate connected to one of the horizontal plates, and these slide rails are arranged along the height of the wall formwork. The horizontal plate of the first steel plate away from the second-channel slide rails and the connected vertical plate form a first embedded end, and the second-channel slide rails on the first steel plate are first connectors. The horizontal plate of the second steel plate away from the second-channel slide rails and the connected vertical plate form a second embedded end, and the second-channel slide rails on the second steel plate are second connectors. The multiple second-channel slide rails of the first steel plate engage and lock with the horizontal plate of the second steel plate close to the second-channel slide rails. Simultaneously, the multiple second-channel slide rails of the second steel plate engage and lock with the horizontal plate of the first steel plate close to the second-channel slide rails.

[0016] Furthermore, the inner sides of the upper and lower openings of the second groove slide rail are both provided with a second chamfer to form a trumpet shape.

[0017] Furthermore, the second grooved slide rail extends to form a second connecting plate, and the second connecting plate of the second grooved slide rail of the first steel plate is welded to the vertical plate of the first steel plate; the second connecting plate of the second grooved slide rail of the second steel plate is welded to the vertical plate of the second steel plate.

[0018] On the other hand, embodiments of the present invention provide a shear wall, including a first precast wall formwork, a second precast wall formwork, and several connecting structures. Both the first and second precast wall formworks are L-shaped, and their openings are arranged opposite to each other to form a T-shaped shear wall. A first horizontal reinforcing bar for the shear wall is provided inside the first precast wall formwork. A first connecting component is embedded in the first precast wall formwork at the long wall position of the shear wall. The first horizontal reinforcing bar is located on the side of the first connecting component away from the second precast wall formwork and is welded to the first embedded end. A second horizontal reinforcing bar for the shear wall is provided inside the second precast wall formwork. A second connecting component is embedded in the second precast wall formwork at the long wall position of the shear wall. The second horizontal reinforcing bar is located on the side of the second connecting component away from the first precast wall formwork and is welded to the second embedded end. The first and second precast wall formworks are connected by several connecting structures to achieve tension.

[0019] Furthermore, two fourth steel plates are fixed to the top of both the first connecting component and the second connecting component. The fourth steel plates are L-shaped, and the open ends of the two fourth steel plates are fixed to the sides of the first steel plate or the second steel plate, forming a receiving groove between the two fourth steel plates. When the two shear walls are stacked vertically, the first steel plate or the second steel plate located above is inserted into the corresponding receiving groove located below.

[0020] (III) Beneficial Effects

[0021] The beneficial effects of this invention are:

[0022] The present invention provides a connection structure between wall formworks on both sides of a shear wall. By providing a first connecting component pre-embedded in the first precast wall formwork forming the shear wall and a second connecting component pre-embedded in the second precast wall formwork forming the shear wall, and by fixing the first connecting component and the second connecting component to connect the first steel plate in the first connecting component and the second steel plate in the second connecting component, an effective connection between the first connecting component and the second connecting component can be achieved. This makes the installation of the first connecting component and the second connecting component convenient, quick, and highly accurate, greatly improving installation efficiency.

[0023] This invention discloses a shear wall system. By incorporating several connecting structures between the first and second precast wall formworks for connection between the two wall formworks, the first and second steel plates in these connecting structures replace the longitudinal reinforcing bars of the shear wall and are welded to the first and second horizontal reinforcing bars of the shear wall, respectively. The first and second connecting components are then connected to achieve tension between the first and second precast wall formworks. This eliminates the need for on-site binding of the first and second horizontal reinforcing bars, allowing them to be directly embedded in the first and second precast wall formworks. This provides the same performance as traditional steel mesh, while offering convenient, quick, and precise installation, significantly improving installation efficiency and greatly reducing on-site workload.

[0024] In addition, the connecting structure allows the first precast wall formwork, the second precast wall formwork, and the cast-in-place concrete to be effectively superimposed as part of the shear wall, forming a complete load-bearing whole. This enables the first precast wall formwork and the second precast wall formwork to jointly participate in the structural load-bearing, reducing the use of materials and increasing the usable indoor building area.

[0045] To better explain and facilitate understanding of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] On the one hand, such as Figure 1-12 As shown, the present invention provides a shear wall, such as Figure 4-6 , Figure 10-12As shown, the structure includes a first precast wall formwork 4, a second precast wall formwork 5, several connecting structures, and cast-in-place concrete. Both the first and second precast wall formworks 4 and 5 are L-shaped concrete slabs cast from fiber-reinforced concrete. The openings of the first and second precast wall formworks 4 and 5 are positioned opposite each other, and concrete is poured into the cavity between them to form a T-shaped shear wall. The first and second precast wall formworks 4 and 5 are connected by several connecting structures to achieve tension. These connecting structures effectively connect the first and second precast wall formworks 4 and 5, improving their integration and installation efficiency. Furthermore, the connecting structures integrate the first and second precast wall formworks 4 and 5 with the cast-in-place concrete to form a complete load-bearing unit, becoming part of the shear wall, thus improving material utilization and increasing the usable indoor building area.

[0047] Shear walls consist of long wall sections and short wall sections. The short wall sections contain a steel cage formed by traditional longitudinal bars and stirrups. The upper end of the longitudinal bars is a mechanical sleeve used for lap splicing the longitudinal bars when two shear walls are vertically stacked.

[0048] like Figure 4-5 , Figure 10-11 As shown, the first precast wall formwork 4 of the long wall section is provided with the first horizontal steel bar 41 of the shear wall. The first precast wall formwork 4 at the position of the long wall forming the shear wall is pre-embedded with the first connecting component 1. The first horizontal steel bar 41 is located on the side of the first connecting component 1 away from the second precast wall formwork 5 and is welded to the first pre-embedded end of the first steel plate 11.

[0049] like Figure 4 , Figure 10 As shown, the second precast wall formwork 5 is provided with a second horizontal steel bar 51 for the shear wall. The second precast wall formwork 5, which forms the long wall position of the shear wall, is pre-embedded with a second connecting component 2. The second horizontal steel bar 51 is located on the side of the second connecting component 2 away from the first precast wall formwork 4 and is welded to the second pre-embedded end of the second steel plate 21.

[0050] The first steel plate 11 and the second steel plate 21 eliminate the need for on-site binding of the first horizontal reinforcing bars 41 and 51 of the shear wall. Instead, they are directly embedded in the first precast wall formwork 4 and the second precast wall formwork 5. At the same time, by setting the first connecting component 1 and the second connecting component 2 respectively, the first steel plate 11 and the second steel plate 21 therein replace the longitudinal reinforcing bars of the shear wall, which also reduces the binding of the longitudinal reinforcing bars and significantly reduces the amount of on-site binding work.

[0051] As can be seen, the first connecting component 1 and the second connecting component 2 serve both as longitudinal reinforcement and as a means to tighten the first precast wall formwork 4 and the second precast wall formwork 5, thus achieving the same performance as traditional steel mesh. This allows for convenient, quick, and high-precision installation of the wall formwork on both sides of the shear wall, significantly improving installation efficiency.

[0052] Since the longitudinal reinforcement of the shear wall is replaced by the first steel plate 11 and the second steel plate 21 in the long wall section, the fourth steel plate 8 is set as the lap steel plate. When the two shear walls are vertically stacked, the first steel plate 11 and the second steel plate 21 of the same layer are lapped with the corresponding first steel plate 11 and the second steel plate 21 of the adjacent layer.

[0053] Specifically, such as Figure 5-6 , Figure 11-12 The top ends of the first connecting component 1 and the second connecting component 2 are each fixed with two fourth steel plates 8. The fourth steel plates 8 are L-shaped, and the open ends of the two fourth steel plates 8 are fixed to the two sides of the first steel plate 11 or the second steel plate 21 respectively. A receiving groove 81 is formed between the two fourth steel plates 8.

[0054] When two shear walls are stacked vertically, the first steel plate 11 or the second steel plate 21 located on top is inserted into the corresponding receiving groove 81 located on the bottom.

[0055] Installation method:

[0056] First, a first precast wall formwork 4 and a second precast wall formwork 5 are produced. The first connecting component 1 and the second connecting component 2 are pre-embedded in the long wall sections of the first precast wall formwork 4 and the second precast wall formwork 5. Then, the first connecting component 1 and the second connecting component 2 are installed. Finally, a steel cage formed by traditional longitudinal bars and stirrups is pre-embedded in the short wall sections of the first precast wall formwork 4 and the second precast wall formwork 5.

[0057] Finally, concrete was poured into the cavity between the first precast wall formwork 4 and the second precast wall formwork 5 to complete the construction of the shear wall.

[0058] On the other hand, the present invention provides a connection structure between the wall formworks on both sides of a shear wall and a shear wall. The specific structures of the first connecting component 1 and the second connecting component 2 are provided in two embodiments in the present invention, as follows:

[0059] Example 1

[0060] like Figure 1-6As shown, the present invention provides a connection structure between wall formworks on both sides of a shear wall, including a first connecting component 1 and a second connecting component 2. The first connecting component 1 includes a first steel plate 11 and a first connector. The first steel plate 11 includes a first embedded end, which is used to be embedded within a first prefabricated wall formwork 4 forming the shear wall. The first connector is fixed to the end of the first steel plate 11 away from the first embedded end. The cross-section of the first steel plate 11 is L-shaped, with a horizontal portion and a partially vertical portion forming the first embedded end. In this embodiment, the first connector is a first grooved slide rail 12. Multiple first grooved slide rails 12 are fixed to the vertical portion of the first steel plate 11 and arranged along the height direction of the first prefabricated wall formwork 4.

[0061] The second connecting assembly 2 includes a second steel plate 21 and a second connector. The second steel plate 21 includes a second embedded end, which is used to be embedded in the second precast wall mold 5 that forms the shear wall. The second connector is fixed to the end of the second steel plate 21 away from the second embedded end. The cross-section of the second steel plate 21 is L-shaped, with a horizontal portion and a partially vertical portion forming the second embedded end. In this embodiment, the second connector is a third steel plate 22. The third steel plate 22 is welded to the end of the second steel plate 21 with the vertical portion of its cross-section. The plane containing the third steel plate 22 is perpendicular to the plane containing the second steel plate 21, and the heights of the third steel plate 22 and the second steel plate 21 are the same.

[0062] The first connecting component 1 and the second connecting component 2 are inserted into all the first groove slide rails 12 through the third steel plate 22 and locked together with all the first groove slide rails 12.

[0063] Preferably, such as Figure 3 As shown, the inner sides of the upper and lower openings of the first groove-shaped slide rail 12 are both provided with first chamfers 121 to form a flared shape, which allows for precise and quick assembly whether the second precast wall mold 5 is fitted with the already placed first precast wall mold 4 or the first precast wall mold 4 is fitted with the already placed second precast wall mold 5. Meanwhile, as... Figure 2 , Figure 3 As shown, in order to strengthen the connection between the first grooved slide rail 12 and the first steel plate 11 and prevent the first grooved slide rail 12 from deforming and shifting after being subjected to force, first connecting plates 122 extend from both sides of the first grooved slide rail 12, and both first connecting plates 122 are welded to the vertical part of the cross section of the first steel plate 11.

[0064] Preferably, the thickness of the first steel plate 11 and the second steel plate 21 ranges from 3mm to 10mm, and the material is steel with a strength grade of Q235 or higher.

[0065] like Figure 5-6As shown, the first steel plate 11 is at the same height as the first precast wall formwork 4, and the second steel plate 21 is at the same height as the second precast wall formwork 5. Both the first steel plate 11 and the second steel plate 21 have multiple vertical through holes 3 for accommodating the horizontal reinforcement 71 of the beam 7 connected to the shear wall.

[0066] Example 2

[0067] like Figure 7-12 As shown, the present invention provides a connection structure between wall formworks on both sides of a shear wall, including a first connecting component 1 and a second connecting component 2. The first connecting component 1 and the second connecting component 2 have the same structure and are symmetrically arranged about the center of the shear wall. The first connecting component 1 includes a first steel plate 11 and a first connector. The first steel plate 11 includes a first embedded end, which is used to be embedded in the first prefabricated wall formwork 4 forming the shear wall. The first connector is fixed to the end of the first steel plate 11 away from the first embedded end. The first steel plate 11 includes an integrally formed vertical plate 111 and horizontal plates 112 respectively connected to both ends of the vertical plate 111. The two horizontal plates 112 extend in opposite directions. A plurality of second grooved slide rails 13 are welded to the portion of the vertical plate 111 connected to one of the horizontal plates 112. The plurality of second grooved slide rails 13 are arranged along the height direction of the wall formwork. The horizontal plate 112 of the first steel plate 11, which is away from the second grooved slide rail 13, and the connected vertical plate 111 form the first embedded end. In this embodiment, the first connecting member is the second grooved slide rail 13 on the first steel plate 11.

[0068] The second connecting assembly 2 includes a second steel plate 21 and a second connector. The second steel plate 21 includes a second embedded end, which is used to be embedded in the second precast wall formwork 5 that forms the shear wall. The second connector is fixed to the end of the second steel plate 21 away from the second embedded end. The second steel plate 21 also includes an integrally formed vertical plate 111 and horizontal plates 112 connected to both ends of the vertical plate 111 respectively. The two horizontal plates 112 extend in opposite directions. A plurality of second grooved slide rails 13 are welded to a portion of the vertical plate 111 connected to one of the horizontal plates 112. The plurality of second grooved slide rails 13 are arranged along the height direction of the wall formwork. The horizontal plate 112 away from the second grooved slide rails 13 and the connected portion of the vertical plate 111 of the second steel plate 21 form the second embedded end. In this embodiment, the second connector is the second grooved slide rail 13 on the second steel plate 21.

[0069] The first connecting assembly 1 and the second connecting assembly 2 are inserted into the first steel plate 111 via a horizontal plate 112 near the second groove slide rail 13, and locked in place with the second groove slide rail 13. At the same time, the horizontal plate 112 of the first steel plate 11 near the second groove slide rail 13 is inserted into the second steel plate 21 via a horizontal plate 112, and locked in place with the second groove slide rail 13.

[0070] Preferably, such as Figure 9 As shown, the inner sides of the upper and lower openings of the second groove-shaped slide rail 13 are both provided with second chamfers 131 to form a flared shape. This ensures precise and quick assembly, whether the second precast wall mold 5 is fitted with the already placed first precast wall mold 4 or the first precast wall mold 4 is fitted with the already placed second precast wall mold 5. Meanwhile, as... Figure 7 , Figure 9 As shown, to strengthen the connection between the second grooved slide rail 13 and the first steel plate 11, and the connection between the second grooved slide rail 13 and the second steel plate 21, and to prevent the first grooved slide rail 12 from deforming and shifting under stress, a second connecting plate 132 extends from the second grooved slide rail 13. The second connecting plate 132 of the second grooved slide rail 13 on the first steel plate 11 is welded to the vertical plate 111 of the first steel plate 11. The second connecting plate 132 of the second grooved slide rail 13 on the second steel plate 21 is welded to the vertical plate 111 of the second steel plate 21.

[0071] Preferably, the thickness of the first steel plate 11 and the second steel plate 21 ranges from 3mm to 10mm, and the material is steel with a strength grade of Q235 or higher.

[0072] like Figure 11-12 As shown, the first steel plate 11 is at the same height as the first precast wall formwork 4, and the second steel plate 21 is at the same height as the second precast wall formwork 5. Both the first steel plate 11 and the second steel plate 21 have multiple vertical through holes 3 for accommodating the horizontal reinforcement 71 of the beam 7 connected to the shear wall.

[0073] The thickness range of the first grooved slide rail 12 and the second grooved slide rail 13 is 8mm-16mm.

[0074] Compared to Example 2, Example 1 involves an additional welding step because the second steel plate 21 is also welded with a third steel plate 22. However, from an installation perspective, since it is only necessary to align one side of the third steel plate 22 and insert it into all the first grooved slide rails 12, the installation is simpler than that of Example 2.

[0075] In Embodiment 2, since the first connecting component 1 and the second connecting component 2 have the same structure, they can be manufactured as standard parts for mass production. Moreover, the first steel plate 11 and the second steel plate 21 are both integrally formed bent parts, reducing welding and simplifying processing. However, from an installation perspective, since the horizontal plates 112 on both sides need to be aligned and inserted into the corresponding second grooved slide rails 13, the installation is more complex than in Embodiment 1, but the tension strength is also higher.
