Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to a prefabricated wall structure. Background Technology

[0002] Precast wall structures are building structures that utilize precast concrete components or steel structural parts, which are prefabricated in a factory and then assembled on-site using reliable connection methods. This technology is mainly divided into two categories: precast concrete structures and steel structure systems. Its core advantages lie in standardized design, factory production, and assembly-based construction, which can significantly reduce on-site work, shorten construction time, improve project quality, and reduce energy consumption, meeting the requirements of modern green building.

[0003] In existing technologies, prefabricated wall structures require hoisting to position them in a designated location before installation. Typically, hoisting relies on lifting rings or connectors embedded in the top of the wall. However, traditional lifting ring structures are often vertically embedded in the wall, and the upward pulling force during hoisting acts directly on the connection between the lifting ring and the wall, easily leading to loosening or even damage, affecting structural safety and durability.

[0004] Furthermore, to ensure the temporary stability of the wall before casting, it is usually necessary to drill holes on the outside of the wall to install temporary support frames. After installation, the holes are then filled with grout. This process is not only cumbersome and inefficient, but the drilling operation also damages the overall structure of the wall, weakens its load-bearing capacity, and increases later maintenance costs.

[0005] In some existing structures, multiple sets of specialized hoisting plates are pre-embedded within the wall to meet hoisting requirements. While these hoisting plates can improve hoisting safety to some extent, their material and processing costs are high, significantly increasing the overall cost. Furthermore, after installation, the hoisting plates often protrude from the wall surface, affecting not only the wall's flatness and appearance but also potentially hindering subsequent decorative work or component installation, requiring additional cutting or sealing, further increasing construction complexity and cost.

[0006] Therefore, existing prefabricated wall structures still have significant shortcomings in terms of hoisting reliability, structural integrity, construction convenience, and cost control. There is an urgent need for an improved solution that can achieve safe hoisting, avoid structural damage, simplify the construction process, and reduce overall costs. Utility Model Content

[0007] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a prefabricated wall structure. By fixing the lifting point mechanism to the internal support mechanism, the lifting load is borne by the internal support mechanism as a whole, which disperses the concentrated stress of the traditional vertically embedded lifting rings and significantly improves the safety and reliability of the lifting process. By opening grooves on the side of the wall body to accommodate the lifting components, the lifting components are prevented from protruding from the wall surface, ensuring the flatness and structural integrity of the wall and facilitating subsequent decoration or installation. By replacing the lifting plate with the lifting point mechanism, the structural strength of the wall can be enhanced and the construction cost can be effectively reduced.

[0008] This utility model is achieved through the following technical solution: A prefabricated wall structure includes a prefabricated wall body, wherein the wall body is provided with an internal support mechanism and a lifting point mechanism, wherein: The internal support mechanism includes multiple sets of longitudinal support members and transverse support members, which are fixedly connected, and the multiple sets of longitudinal support members and transverse support members are arranged at intervals respectively; The lifting point mechanism is fixedly connected to the internal support mechanism. Multiple sets of grooves are opened on the side of the wall body. The lifting point mechanism includes a fixedly connected fixing component and a triangular lifting component. The fixing component is cast and embedded in the wall body and is fixedly connected to the internal support mechanism. The lifting component is set in the groove and is used to lock the lifting device. An extension groove extending to the top of the wall body is opened at the top of the groove and is used to limit the lifting cable.

[0009] As can be seen, in the above technical solution, by fixing the lifting point mechanism to the internal support mechanism, the lifting load is borne entirely by the internal support mechanism, which disperses the concentrated stress of the traditional vertically embedded lifting rings and significantly improves the safety and reliability of the lifting process. By opening grooves on the side of the main wall to accommodate the lifting components, the lifting components are prevented from protruding from the wall surface, ensuring the flatness and structural integrity of the wall and facilitating subsequent decoration or installation. The extension groove can position and limit the slings, preventing slippage and improving the positioning accuracy and operational safety of the lifting. This structure achieves reliable lifting while eliminating the need to drill holes in the external wall for temporary support, protecting the integrity of the wall structure and simplifying the construction process. By replacing the lifting plate with the lifting point mechanism, the strength of the wall structure can be enhanced, and construction costs can be effectively reduced.

[0010] According to the above technical solution, preferably, the lower end of the longitudinal support extends out of the wall body to form a lower connecting part that connects with the lower structure.

[0011] As can be seen, in the above technical solution, the lower end of the longitudinal support extends to form a lower connecting part, which facilitates a quick and effective connection between the main body of the wall and the lower structure, improves installation efficiency, and enhances the vertical force transmission performance of the wall and the stability of the overall structure.

[0012] According to the above technical solution, preferably, the upper end of the longitudinal support extends out of the wall body to form an upper connecting part that connects with the upper structure. The upper connecting part is an L-shaped and triangular structure arranged in an alternating manner.

[0013] As can be seen, in the above technical solution, the upper end of the longitudinal support extends to form an upper connecting part of a specific shape. The upper connecting part adopts an interlaced L-shaped and triangular structure, which increases the connection contact surface with the upper structure, improves the node connection strength and load transfer efficiency, and helps to enhance the overall integrity and seismic performance of the structure.

[0014] According to the above technical solution, preferably, the longitudinal support and the transverse support are fixedly connected by binding or welding, and the transverse support is a ring structure.

[0015] As can be seen, in the above technical solution, the longitudinal support and the transverse support are fixedly connected by binding or welding, which ensures the connection reliability of the internal support mechanism; setting the transverse support as a ring structure can effectively constrain the longitudinal support, improve the overall rigidity and stability of the internal support mechanism, and thus improve the stress performance of the wall body during hoisting and use.

[0016] According to the above technical solution, preferably, the fixing member is arranged horizontally, and both the fixing member and the hoisting member are fixedly connected to the longitudinal support member.

[0017] As can be seen, in the above technical solution, this structure enables the lifting tension to be directly and efficiently transmitted to the longitudinal support, which is the main load-bearing component, thus optimizing the force transmission path, reducing the risk of stress concentration in the lifting point area, and further ensuring lifting safety.

[0018] According to the above technical solution, preferably, two of the grooves form a group, and the grooves are distributed at the outer corners of the main body of the wall. When there are two groups of grooves, the grooves are arranged in a rectangular four-corner arrangement.

[0019] As can be seen, in the above technical solution, this symmetrical arrangement can make the force on each lifting point uniform during hoisting, which is conducive to maintaining the balance and stability of the wall during the hoisting process, reducing tilting and internal stress concentration, and improving hoisting safety and positioning accuracy.

[0020] According to the above technical solution, preferably, both the inner walls of the groove and the extension groove are provided with rough portions, and the rough portions have several groove marks.

[0021] As can be seen, in the above technical solution, the rough part with several groove marks on the inner wall of the groove and the extension groove can greatly increase the frictional resistance between the lifting parts, the slings and the groove wall, effectively prevent the lifting parts from shifting in the groove, and strengthen the limiting effect on the slings, thereby improving the stability and reliability of the entire lifting system.

[0022] According to the above technical solution, preferably, the groove is horizontal or oblique.

[0023] The beneficial effects of this utility model are: (1) This patent connects the lifting point mechanism with the inner support mechanism in a fixed manner, so that the lifting load is borne by the inner support mechanism as a whole, which disperses the concentrated stress of the traditional vertically buried lifting ring and significantly improves the safety and reliability of the lifting process. (2) This patent has a groove on the side of the main body of the wall to accommodate the hoisting parts, which avoids the hoisting parts from protruding from the wall surface, ensuring the flatness of the wall appearance and the integrity of the structure, and is conducive to subsequent decoration or installation construction. (3) The extension groove of this patent can position and limit the sling, prevent the sling from slipping, improve the positioning accuracy and operation safety of the hoisting. While achieving reliable hoisting, this structure eliminates the need to drill holes in the outer wall for temporary support, protects the integrity of the wall structure, and simplifies the construction process. (4) This patent replaces the lifting plate with a lifting point mechanism, which not only enhances the strength of the wall structure, but also effectively reduces construction costs.

[0027] like Figure 1-4 As shown, this embodiment provides a prefabricated wall structure, including a prefabricated wall body 1. The wall body 1 contains an internal support mechanism 2 and a lifting mechanism 3. The internal support mechanism 2 includes multiple sets of longitudinal support members 4 and transverse support members 5, which are fixedly connected. The multiple sets of longitudinal support members 4 and transverse support members 5 are spaced apart. The lifting mechanism 3 is fixedly connected to the internal support mechanism 2. Multiple grooves 6 are formed on the side of the wall body 1. The lifting mechanism 3 includes a fixedly connected fixing member 12 and a triangular lifting member 13. The fixing member 12 is cast and embedded in the wall body 1 and is fixedly connected to the internal support mechanism 2. The lifting member 13 is set in the groove 6 and is used to lock the lifting device. An extension groove 7 extending to the top of the wall body 1 is formed at the top of the groove 6. The extension groove 7 is used to limit the lifting cable. After the lifting construction is completed, fine stone concrete can be used to fill the groove. After the grooves 6 and 7 are filled, the construction is simple and convenient. In this embodiment, by fixing the lifting point mechanism 3 to the inner support mechanism 2, the lifting load is borne by the inner support mechanism 2 as a whole, which disperses the concentrated stress of the traditional vertically embedded lifting ring and significantly improves the safety and reliability of the lifting process. By opening the groove 6 on the side of the wall body 1 to accommodate the lifting component 13, the lifting component 13 is prevented from protruding from the wall surface, ensuring the flatness and structural integrity of the wall and facilitating subsequent decoration or installation. The extension groove 7 can position and limit the sling, preventing the sling from slipping and improving the positioning accuracy and operational safety of the lifting. This structure can achieve reliable lifting while eliminating the need to drill holes in the outer wall to set up temporary supports, protecting the integrity of the wall structure and simplifying the construction process. By replacing the lifting plate with the lifting point mechanism, the strength of the wall structure can be enhanced and the construction cost can be effectively reduced.

[0028] Optionally, in one possible implementation, the lower end of the longitudinal support 4 extends out of the wall body 1 to form a lower connecting part 8 that connects with the lower structure, which facilitates a quick and effective connection between the wall body 1 and the lower structure, improves installation efficiency, and enhances the vertical force transmission performance of the wall and the stability of the overall structure.

[0029] Optionally, in one possible implementation, the upper end of the longitudinal support 4 extends out of the wall body 1 to form an upper connection part 9 that connects to the superstructure.

[0030] Optionally, in one possible implementation, the longitudinal support 4 and the transverse support 5 are fixedly connected by binding or welding to ensure the connection reliability of the inner support mechanism 2. The transverse support 5 is a ring structure, which can effectively constrain the longitudinal support 4, improve the overall rigidity and stability of the inner support mechanism 2, and thus improve the stress performance of the wall body 1 during hoisting and use.

[0031] Optionally, in one possible implementation, the fixing member 12 is arranged laterally, and both the fixing member 12 and the lifting member 13 are fixedly connected to the longitudinal support member 4. This structure allows the lifting tension to be directly and efficiently transmitted to the longitudinal support member 4, which is the main load-bearing component, thus optimizing the force transmission path, reducing the risk of stress concentration in the lifting point area, and further ensuring the safety of lifting.

[0032] Optionally, in one possible implementation, two grooves 6 form a group, and the grooves 6 are distributed at the outer corners of the wall body 1. When there are two groups of grooves 6, the grooves 6 are arranged in a rectangular four-corner arrangement. This symmetrical arrangement can make the force on each lifting point uniform during hoisting, which is conducive to maintaining the balance and stability of the wall during the hoisting process, reducing tilting and internal stress concentration, and improving hoisting safety and positioning accuracy.

[0033] Optionally, in one possible implementation, both the inner walls of the groove 6 and the extension groove 7 are provided with rough portions 10, and the rough portions 10 have several grooves, which are horizontal or oblique.
