AI Technical Summary
In existing prefabricated building construction, it is difficult to ensure that the lifting point and the center of gravity of the building to be lifted are on the same vertical line, which leads to safety hazards during the lifting process, such as rolling or overturning.
The system employs a combination structure of a hoisting frame, hoisting beam, hoisting plate, and several hooks. By adjusting the position of the hooks, the center of gravity of the connecting hook and the building to be hoisted is aligned as much as possible on a vertical line. Stability is ensured by using connecting screws, nuts, and washers. The position of the hoisting beam is further optimized by adjusting the position of the frame through longitudinal and transverse movement to improve the alignment of the center of gravity.
It improves the stability and safety of the hoisting process, reduces the rolling and overturning of prefabricated buildings during hoisting, and enhances hoisting efficiency and safety.

Description
Technical Field
[0001] This application relates to the field of hoisting structures for building construction, and particularly to a hoisting structure for prefabricated building construction. Background Technology
[0002] Prefabricated construction is an important way to modernize the construction industry, and prefabricated buildings have become an important future development direction for my country's construction industry. The precise, efficient, and safe hoisting of prefabricated components is one of the key challenges in on-site construction of prefabricated buildings.
[0003] In related technologies, hoisting equipment for prefabricated building construction typically relies on a combination of tower cranes or other hoisting drives and hooks. The hooks connect to the building to be hoisted, and the tower cranes or other hoisting drives output power to achieve the hoisting of the prefabricated building. However, due to errors in the position of the hoisting point and the center of gravity between the hook and the building to be hoisted, the center of gravity of the building components may shift during the hoisting process, which may cause the components to roll or become unstable in the air, resulting in the building to be hoisted rolling or even overturning, posing a safety hazard.
[0004] Therefore, it is necessary to propose a hoisting structure for prefabricated building construction to improve the stability of hoisting, which has become an important technical problem that urgently needs to be solved. Utility Model Content
[0005] This application provides a hoisting structure for prefabricated building construction, aiming to solve the problem that existing hoisting structures cannot ensure that the hoisting point and the center of gravity of the building to be hoisted are on the same vertical line, which can lead to the building rolling or even overturning, posing a safety hazard.
[0006] To achieve the above objectives, this application proposes a hoisting structure for prefabricated building construction, comprising: a hoisting frame; a hoisting beam disposed on the hoisting frame and equipped with connecting hooks connected to a hoisting drive; a hoisting plate disposed on the hoisting frame and provided with a plurality of connecting holes at intervals; and a plurality of hooks disposed in the connecting holes and connected to the building to be hoisted.
[0007] In some embodiments, the device further includes: a connecting screw, wherein the hook is provided with a threaded hole through which the connecting screw passes, and the connecting screw is adapted to the connecting hole; and a nut, which is screwed onto the connecting screw.
[0008] In some embodiments, the device further includes: a first washer disposed between the connecting screw and the hook; a second washer disposed between the hoisting plate and the hook; and a third washer disposed between the nut and the hoisting plate.
[0009] In some embodiments, the system further includes: two longitudinal sliding frames fitted onto a hoisting frame, the two longitudinal sliding frames being disposed at both ends of the hoisting beam; a plurality of first positioning holes, the hoisting frame being provided with a plurality of first positioning holes at intervals; a positioning plate, the positioning plate being disposed on the longitudinal sliding frame; and a first positioning screw, the first positioning screw being disposed on the positioning plate, both the longitudinal sliding frame and the positioning plate being provided with threaded holes through which the first positioning screw passes.
[0010] In some embodiments, the system further includes a reinforcing plate disposed on the hoisting frame, the reinforcing plate having a second positioning hole adapted to the first positioning hole.
[0011] In some embodiments, the system further includes: a transverse frame movably disposed on the hoisting beam, a connecting hook disposed on the transverse frame; a plurality of third positioning holes spaced apart on the hoisting beam; and a second positioning screw disposed on the transverse frame, the transverse frame having a threaded hole through which the second positioning screw passes.
[0012] This application proposes a hoisting structure for prefabricated building construction, comprising: a hoisting frame, a hoisting beam, a hoisting plate, and several hooks. The hoisting beam is disposed within the hoisting frame and is equipped with connecting hooks that connect to a hoisting drive. The hoisting plate is disposed within the hoisting frame and has several connecting holes spaced apart. Several hooks are disposed within the connecting holes and connect to the building to be hoisted. During the construction of prefabricated buildings, due to the heavy weight of the prefabricated building, a hoisting drive and hoisting structure are required to hoist the prefabricated building and place it in a predetermined position to form the prefabricated building. During construction hoisting, multiple hooks can simultaneously move multiple prefabricated buildings, improving hoisting efficiency. The hook positions can be adjusted according to the weight of different prefabricated buildings, ensuring that the center of gravity of the connecting hook and the hoisting structure connecting the prefabricated building is as close to a vertical line as possible. When using multiple hooks to hoist a single prefabricated building, the hook positions can also be adjusted according to the building's mass distribution, ensuring that the center of gravity of the connecting hook and the hoisting structure connecting the prefabricated building is as close to a vertical line as possible, minimizing deviations and reducing rolling, tilting, or overturning caused by center of gravity shifts. This prevents the prefabricated building from rolling or even overturning during hoisting, improving the safety of the operation. Attached Figure Description

[0025] See Figure 1 As shown, this application proposes a hoisting structure for prefabricated building construction, including: a hoisting frame 1; a hoisting beam 5, which is disposed on the hoisting frame 1 and is provided with a connecting hook 3, which is connected to a hoisting drive; a hoisting plate 6, which is disposed on the hoisting frame 1 and is provided with a plurality of connecting holes 61 at intervals; and a plurality of hooks 8, which are provided with the connecting holes 61 and are connected to the building to be hoisted.
[0026] The hoisting frame 1 is a basic component of a hoisting structure for prefabricated building construction. Other structures in the hoisting structure are directly or indirectly connected to the hoisting frame 1. The hoisting frame 1 is roughly C-shaped. The open end of the hoisting frame 1 is used to insert the hoisting beam 5. The connecting hook 3 is set on the hoisting beam 5. The connecting hook 3 is the hoisting point of the hoisting structure for prefabricated building construction. The hoisting drive can be any one of tower crane, crane, crane, etc. The hoisting plate 6 is connected to the hoisting frame 1 and is the structural foundation of several hooks 8. Several connecting holes 61 are provided at intervals on the hoisting plate 6. The hooks 8 are connected to the hoisting plate 6 through the connecting holes 61. In this embodiment, the hook 8 includes a connecting end, a hinge connecting the connecting end, and a hook connecting the hinge. The hook 8 is connected to the hoisting plate 6 through the connecting end and connected to the building to be hoisted through the hook.
[0027] Specifically, during the construction of prefabricated buildings, due to the heavy weight of the prefabricated structures, hoisting drives and hoisting structures are needed to lift and place them in predetermined positions to form the prefabricated building. During the hoisting process, several hooks 8 can simultaneously move multiple prefabricated buildings, improving hoisting efficiency. The positions of the hooks 8 can be adjusted according to the weight of different prefabricated buildings, ensuring that the center of gravity of the connecting hook 3 and the hoisting structure connecting the prefabricated building is as close as possible to a vertical line. When using multiple hooks 8 to lift a single prefabricated building, the positions of the hooks 8 can also be adjusted according to the weight distribution of the prefabricated building, ensuring that the center of gravity of the connecting hook 3 and the hoisting structure connecting the prefabricated building is as close as possible to a vertical line, minimizing deviations and reducing rolling, tilting, or overturning caused by center of gravity shifts. This prevents the prefabricated building from rolling or even overturning during hoisting, improving the safety of the hoisting process.
[0028] Among them, the hook of hook 8 is made of 20SiMn steel. 20SiMn steel has excellent mechanical properties and toughness, which enables the hook to withstand the impact load generated by the prefabricated building during starting and braking.
[0029] See Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the system further includes: a connecting screw 10; a hook 8 having a threaded hole through which the connecting screw 10 passes; the connecting screw 10 fitting into a connecting hole 61; and a connecting end of the hook 8 having a threaded hole through which the screw passes. The connecting screw 10 is screwed into the connecting hole 61 and partially extends out of the connecting hole 61. A nut 11 is screwed onto the connecting screw 10. The nut 11 is screwed onto the end of the connecting screw 10 extending out of the connecting hole 61 and abuts against the lifting plate 6, thereby fixing the position of the connecting screw 10 and achieving the purpose of fixing the position of the hook 8.
[0030] See Figure 1 , Figure 3 and Figure 4 As shown, in some embodiments, the system further includes: a first washer 13, which is disposed between the connecting screw 10 and the hook 8; a second washer 12, which is disposed between the lifting plate 6 and the hook 8; and a third washer, which is disposed between the nut 11 and the lifting plate 6. To ensure the stability of the connection between the hook 8 and the lifting plate 6, a preload is required on the connecting screw 10 and the nut 11. To prevent damage to the connecting end of the hook 8 and the lifting plate 6, the first washer 13, the second washer 12, and the third washer are provided, effectively protecting the connecting end of the hook 8 or the lifting plate 6. Furthermore, the placement of the first washer 13, the second washer 12, and the third washer effectively prevents the connecting screw 10 or the nut 11 from loosening.
[0031] See Figure 1 , Figure 5 and Figure 6As shown, in some embodiments, it further includes: two longitudinal sliding frames 2, which are fitted onto the hoisting frame 1 and are respectively disposed at both ends of the hoisting beam 5; the hoisting beam 5 is movably disposed on the hoisting frame 1 through the two longitudinal sliding frames 2. Due to the heavy weight and large volume of the prefabricated building, in some cases, it is still not possible to ensure that the center of gravity of the hoisting structure connecting the prefabricated building to be hoisted and the connecting hook 3 are on the same vertical line by simply adjusting the position of the hook 8. At this time, by adjusting the relative position of the hoisting beam 5 and the longitudinal sliding frames 2, the center of gravity of the hoisting structure connecting the prefabricated building to be hoisted and the connecting hook 3 are roughly on the same vertical line, thereby improving the practicality of the hoisting structure. A plurality of first positioning holes are spaced apart on the hoisting frame 1; a positioning plate 14 is disposed on the longitudinal moving frame 2; a first positioning screw 15 is disposed on the positioning plate 14, and the positioning plate 14 is connected to the hoisting frame 1 via the first positioning screw 15. Both the longitudinal moving frame 2 and the positioning plate 14 are provided with threaded holes for the first positioning screw 15 to pass through. After the hoisting beam 5 is positioned, the position of the hoisting beam 5 relative to the hoisting frame 1 is defined by screwing the first positioning screw 15 into the first positioning hole. The outer diameter of the first positioning screw 15 is adapted to the outer diameter of the hoisting beam 5.
[0032] In this embodiment, the hoisting frame 1 includes one horizontal side and two vertical sides, which form a C-shape. Two longitudinal moving frames 2 are located on the two vertical sides, and a plurality of first positioning holes are provided at intervals on each of the two vertical sides. The first positioning holes are preferably equipped with impact-resistant components to prevent damage to the hoisting frame 1 from impact loads during starting and braking.
[0033] See Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments, it further includes a reinforcing plate 7, which is disposed on the hoisting frame 1 and has a second positioning hole adapted to the first positioning hole. The reinforcing plate 7 is used to thicken the hoisting frame 1 to prevent damage under impact loads during start-up and braking. The inner diameter of the second positioning hole is equal to the inner diameter of the first positioning hole.
[0034] See Figure 1 and Figure 2As shown, in some embodiments, the system further includes: a transverse frame 4, movably mounted on the hoisting beam 5, with a connecting hook 3 mounted on the transverse frame 4; a plurality of third positioning holes 51, spaced apart on the hoisting beam 5; and a second positioning screw 9, mounted on the transverse frame 4, with a threaded hole through which the second positioning screw 9 passes. The transverse frame 4 can move relative to the hoisting beam 5, thereby changing the position of the connecting hook 3, allowing for more flexible position changes and enhancing the practicality of the hoisting structure. After the transverse frame 4 moves to a preset position, the position of the transverse frame 4 relative to the hoisting beam 5 can be limited by screwing the second positioning screw 9 so that it partially extends into the third positioning hole 51. The inner diameter of the third positioning hole 51 is adapted to the outer diameter of the second positioning screw 9.

All equivalent structural transformations made using the content of this application's specification and drawings under the overall concept of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
