[0031] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.

[0032] It should be noted that, unless otherwise specified, the technical or scientific terms used in this application should have the common meanings understood by those skilled in the art to which this application belongs.

[0033] Example 1

[0034] Reference Attachment Figure 1 -Attached Figure 6, the first embodiment of the present invention proposes a thin-shell shear wall prefabricated component, which includes: a first formwork 11 and a second formwork 12, which are spaced apart and arranged opposite to each other in a first direction z, and a casting cavity is formed between the two; and a truss steel bar, which includes: a plurality of steel bar bodies 21, which are spaced apart along the transverse direction x, and the steel bar bodies 21 are alternately provided with first tie segments 211 and second tie segments 212 along their extension direction, and the first tie segments 211 and the second tie segments 212 are connected to the connecting segment 213 therebetween to form a bending portion. 214, the first tie section 211 and the second tie section 212 are respectively tied to the inside of the first formwork 11 and the second formwork 12, and the connection section 213 of the steel bar body 21 is located in the casting cavity and is in the same plane, and the plane is perpendicular to the first formwork 11 and the second formwork 12; wherein, the part of the truss steel bar located inside the first formwork 11 and the second formwork 12 includes at least length segments extending along the transverse direction x and the longitudinal direction y respectively, and the first direction z is perpendicular to the transverse direction x and the longitudinal direction y.

[0035] Specifically, the thin-shell shear wall prefabricated component provided in this embodiment is a prefabricated part of the combined load-bearing formwork shear wall, which jointly bears the structural load to meet the functional requirements of the building. The first formwork 11 and the second formwork 12 are the main prefabricated parts. The two formworks can serve as the outer blade and inner blade of the combined load-bearing formwork shear wall, respectively. The formwork serving as the outer blade is directly exposed to the external environment and needs to have a certain degree of durability and weathering resistance. It can usually be combined with an insulation layer and an exterior decorative panel to form a composite wall structure. The formwork serving as the inner blade and the outer blade can be arranged with a steel mesh, or high-strength concrete or UHPC concrete can be used to enhance the structural strength and bearing capacity. The first formwork 11 and the second formwork 12 can be manufactured using an automated steel formwork table flipping device, and production efficiency and product quality can be improved through assembly line production. The first formwork 11 and the second formwork 12 are spaced apart along a first direction z, and a casting cavity is formed between the two through truss steel bars for pouring concrete on site to form a stable wall structure; wherein the first direction z is perpendicular to the transverse and longitudinal directions, and is the thickness direction of the first formwork 11 and the second formwork 12.

[0036] The truss reinforcement includes a plurality of reinforcement bodies 21, which are arranged at intervals along the transverse direction x in the form of a plane rack. Each reinforcement body 21 is formed by bending a reinforcement bar. Through the bending operation, the reinforcement body 21 can be alternately provided with a first tie segment 211 and a second tie segment 212 along the longitudinal direction y. The first tie segment 211 and the second tie segment 212 are connected by a connecting segment 213. The position where the first tie segment 211 and the connecting segment 213 are connected and the position where the second tie segment 212 and the connecting segment 213 are connected are the bending portions 214. The bending angle of the bending portion 214 is not specifically limited here. In order to ensure that the truss reinforcement is smooth during construction, During the prefabrication process, the first and second tie segments 211 and 212 are not pulled out from the first and second formworks 11 and 12, and the first and second tie segments 211 and 212 are respectively embedded and tied inside the first and second formworks 11 and 12 in the prefabrication stage, and the truss reinforcement is located inside the first and second formworks 11 and 12. The portion of the truss reinforcement that is located inside the first and second formworks 11 and 12 includes at least length segments extending along the transverse x and longitudinal y directions, respectively. This design can ensure a close connection between the truss reinforcement and the internal structure of the formwork, improve the tie effect and reliability, help to enhance the overall structural rigidity and stability, and effectively disperse and transmit stress to avoid stress concentration on site. In order to further improve the tie effect, as shown in the attached Figure 2 As shown, the bending portion 214 and a small portion of the length of the connecting section 213 for achieving the connection can also be located inside the corresponding first mold shell 11 or second mold shell 12.

[0037] It should be noted that the length segments of the truss reinforcement extending along the transverse x and longitudinal y directions may be part of the corresponding first and second tie segments 211 and 212, or may be additional structures that cooperate and connect with the corresponding first and second tie segments 211 and 212.

[0038] In order to avoid the influence of truss steel bars on the vibration of concrete in the casting cavity, the technical solution adopted by the present invention is as follows: Figure 3 As shown, the connecting section 213 of the steel bar body 21 is located in the casting cavity and is in the same plane, and the plane is perpendicular to the first formwork 11 and the second formwork 12. Such a design can simplify the complexity of the structure of the truss steel bars inside the casting cavity, and can effectively reduce the space occupied by the truss steel bars in the casting cavity, thereby minimizing the impact on the vibration of the concrete in the casting cavity.

[0039] According to the above, the embodiment of the present invention proposes a thin-shell shear wall prefabricated component, wherein the first formwork 11 is connected to the second formwork 12 by a truss steel bar, and a casting cavity is formed between the two for on-site pouring of concrete, the truss steel bar includes a plurality of steel bar bodies 21, and the plurality of steel bar bodies 21 are arranged at intervals along the transverse x in the form of a plane rack, each steel bar body 21 is formed by bending a steel bar, and the junctions between the first tie section 211 and the second tie section 212 and the connecting section 213 therebetween form a bending portion 214, respectively, the first tie section 211 and the second tie section 212 are respectively pre-buried and tied to the inside of the first formwork 11 and the second formwork 12, and the truss steel bar is located in the first The internal parts of the formwork 11 and the second formwork 12 include at least length segments extending along the transverse x and longitudinal y directions respectively. Such a design can ensure the close connection between the truss steel bars and the internal structure of the formwork, improve the tensioning effect and reliability, help to enhance the overall structural rigidity and stability, and effectively disperse and transmit stress; the connecting section 213 of the steel bar body 21 is located in the casting cavity and is in the same plane, and the plane is perpendicular to the first formwork 11 and the second formwork 12, which can simplify the complexity of the structure of the truss steel bars inside the casting cavity, minimize the impact on the concrete vibration in the casting cavity, and ensure that the concrete in the casting cavity is vibrated evenly and in place.

[0040] For further information, see the attached Figure 1 -Attached Figure 5 In a specific implementation, the first tie segment 211 and the second tie segment 212 extend along the longitudinal direction y; the truss reinforcement also includes: a plurality of transverse reinforcements 22, each of the first tie segment 211 and each of the second tie segment 212 is respectively connected with the transverse reinforcement 22, and the transverse reinforcement 22 is pre-embedded in the corresponding first formwork 11 or the second formwork 12.

[0041] Specifically, in order to realize that the part of the truss steel bar located inside the first formwork 11 and the second formwork 12 includes at least length segments extending along the transverse x and longitudinal y respectively, in the technical solution adopted by the utility model, the first tie segment 211 and the second tie segment 212 are set as length segments extending along the longitudinal y, which is conducive to simplifying the structure of the steel bar body 21 and reducing the difficulty of bending the steel bar body 21; for this purpose, the truss steel bar also includes a plurality of transverse steel bars 22, and each first tie segment 211 and each second tie segment 212 respectively corresponds to a transverse steel bar 22, and is connected to the transverse steel bar 22. The connection here can be a tied fixed connection, which can reduce the difficulty of connection; by arranging a plurality of transverse steel bars 22 to cooperate with the first tie segment 211 and the second tie segment 212, the effect of stably tying the truss steel bar inside the first formwork 11 and the second formwork 12 can be achieved.

[0042] For further information, see the attached Figure 1 -Attached Figure 5 In order to simplify the structure of the truss steel bars and improve the stability and reliability of the overall structure, in a specific implementation, the first tie segments 211 at the same height are connected to the same transverse steel bar 22; the second tie segments 212 at the same height are connected to the same transverse steel bar 22, that is, only one transverse steel bar 22 is set at the same height in the first formwork 11, and only one transverse steel bar 22 is set at the same height in the second formwork 12. This can reduce the number of transverse steel bars 22, further improve the tie effect, structural strength, and bearing capacity, and also improve the convenience of connecting the truss steel bars and the transverse steel bars 22.

[0043] For further information, see the attached Figure 6 In a specific implementation, the first tie segment 211 and the second tie segment 212 are bent to form a plurality of length segments at angles to each other, and at least include a length segment extending along the transverse direction x and a length segment extending along the longitudinal direction y.

[0044] Specifically, in order to realize that the portion of the truss reinforcement located inside the first formwork 11 and the second formwork 12 includes at least length segments extending in the transverse direction x and the longitudinal direction y respectively, in the technical solution adopted by the present invention, the length segments extending in the transverse direction x and the longitudinal direction y can be formed by bending the reinforcement body 21, that is, the first tie segment 211 and the second tie segment 212 can be further bent, specifically: the first tie segment 211 and the second tie segment 212 are bent to form a plurality of length segments at angles to each other, and these length segments include at least one length segment extending in the transverse direction x and one length segment extending in the longitudinal direction y, so that there is no need to add additional reinforcement structure, and the truss can be simplified. The structural composition of the frame steel bars; among them, optimally, multiple length segments of the first tie segment 211 can be set in the same plane, and the plane is parallel to the first formwork 11. Similarly, multiple length segments of the second tie segment 212 are in the same plane, and the plane is parallel to the second formwork 12. Such a design can form a closer and more stable connection relationship between the tie segment and the corresponding formwork, reduce the thickness of the first formwork 11 and the second formwork 12, and make more effective use of materials. It can also enable the first tie segment 211 and the second tie segment 212 to more effectively resist forces from all directions, thereby enhancing the stability of the overall structure.

[0045] The following describes a bending form of the first tie section 211 and the second tie section 212: Figure 6As shown, the first tie segment 211 and the second tie segment 212 have the same shape, including: a first length segment 21a, a second length segment 21b and a third length segment 21c. The first length segment 21a and the second length segment 21b extend along the transverse direction x respectively and are connected to the connecting segment 213. The third length segment 21c is connected between the first length segment 21a and the second length segment 21b and extends along the longitudinal direction y. Such an arrangement can form two length segments extending along the transverse direction x and one length segment extending along the longitudinal direction y, and the three length segments enclose a stable rectangular space.

[0046] For further information, see the attached Figure 1 -Attached Figure 6 In a specific implementation, the thin-shell shear wall prefabricated component provided in this embodiment also includes: a plurality of vertical steel bars 3, the first formwork 11 and the second formwork 12 respectively correspond to a plurality of vertical steel bars 3, the plurality of vertical steel bars 3 are located in the casting cavity and are evenly arranged along the horizontal direction x, and the vertical steel bars 3 are connected to the corresponding truss steel bars.

[0047] Specifically, setting a number of vertical steel bars 3 and connecting them with the truss steel bars can play an important role in enhancing the integrity and stability of the structure, transferring and distributing loads, and improving seismic performance. At present, the longitudinal y steel bars are usually prefabricated inside the formwork, which will result in a certain limitation on the thickness of the formwork, which can only reduce the importance of the component to a certain extent, and limit the steel bar connection to indirect overlap. To solve the above problems, in the technical solution adopted by the utility model, the first formwork 11 and the second formwork 12 respectively correspond to a plurality of vertical steel bars 3 of equal or similar number, and the plurality of vertical steel bars 3 are arranged in the casting cavity and evenly arranged along the horizontal x direction. The vertical steel bars 3 are connected to the corresponding truss steel bars, and the connection method can be but not limited to welding. By arranging the vertical steel bars 3 outside the first formwork 11 and the second formwork 12, on the one hand, the thickness of the formwork can be reduced, so that the weight of the thin-shell shear wall prefabricated component is lighter, which greatly reduces the invitation to the lifting equipment, and can also increase the plane size of the combined load-bearing formwork shear wall and reduce the connection nodes. On the other hand, when connecting vertically, the upper and lower layers of steel bars can be overlapped to improve the reliability of the connection.

[0048] Example 2

[0050] Specifically, the combined load-bearing formwork shear wall provided in this embodiment utilizes the thin-shell shear wall prefabricated components described above. By pouring concrete on-site within the casting cavity of the prefabricated components, the first and second formworks 11, 12 on either side are connected to form a single, integrated structural system. This enhances the wall's load-bearing capacity and rigidity, while also providing high seismic and wind resistance. The use of the aforementioned thin-shell shear wall prefabricated components ensures that the concrete within the casting cavity is vibrated evenly and in place, while reliably connecting the first and second formworks 11, 12.
