Description

Technical Field

[0001] This utility model relates to the field of structural engineering technology, specifically to a construction structure for the overall lifting of suspended steel structures. Background Technology

[0002] High-span steel structures, with their aesthetically pleasing and grand appearance, are increasingly being used in urban landmark buildings. Traditional construction methods require first designing and installing temporary support frames, then installing the bottom floor beams and columns on these frames, and so on upwards layer by layer. Once all floor beams and columns are installed, the floor slab is poured, and finally, the temporary support frames are removed. However, this method consumes additional steel for the temporary support frames and takes a considerable amount of time. Utility Model Content

[0003] In view of this, the present invention provides a suspended steel structure overall lifting construction structure to solve the problems of the existing technology where temporary support frames consume additional steel and the construction period is relatively long.

[0004] This utility model provides a construction structure for the overall lifting of suspended steel structures, including: The core tube shear wall consists of several units, each with several installation positions along the extension direction; A truss is installed at the top of the core tube shear wall; The slings, located on one side of the core tube shear wall, are detachably mounted on the truss; A floor slab assembly, comprising several stacked floor slabs, wherein the slings are detachably connected to the bottom floor slab. The slings are adapted to lift the floor slab assembly to the installation position opposite to the top floor slab, and also to lower the floor slab assembly layer by layer to the installation position corresponding to each floor slab. The end of the floor slab near the core tube shear wall is connected to the core tube shear wall. Also includes: A hanging column is installed between two adjacent floor slabs at the installation location.

[0005] In this application, slings are used to lift the floor slab assembly as a whole and lower it layer by layer, which avoids the use of temporary support frames in traditional construction, thereby saving a significant amount of extra steel consumption, reducing construction costs, and eliminating the safety hazards caused by temporary supports, thus improving overall construction safety. Secondly, by lifting the floor slab assembly to the design elevation (installation position) in one go using slings, and then lowering it layer by layer for installation, the amount of high-altitude hoisting work is reduced, construction risks are lowered, and the installation speed of the floor slab assembly is increased.

[0006] In one alternative embodiment, one end of the sling is located at the lower chord node of the truss.

[0007] In this application, placing the slings at the lower chord node effectively disperses concentrated stress generated during hoisting, preventing local deformation or damage to the truss and extending the structure's service life. Furthermore, it facilitates the installation and adjustment of the slings, reducing construction complexity and improving operational efficiency. Installing slings at the lower chord node maintains the balance of the floor slab assembly during lifting, preventing tilting or swaying and ensuring precise positioning of the floor slab assembly at the design elevation.

[0008] In one alternative implementation, the other end of the sling is connected to the lower flange of the lowest floor slab.

[0009] In this application, the other end of the sling is connected to the lower flange of the bottom floor slab, which ensures a uniform distribution of lifting force, prevents damage caused by localized stress concentration in the floor slab, and allows the floor slab assembly to rise and fall stably as a whole, reducing the risk of structural deformation. Furthermore, connecting the sling to the lower flange of the bottom floor slab allows for layer-by-layer descent and installation, enabling the installation of upper floor slabs first, followed by lower floor slabs, thus reducing construction time.

[0010] In one alternative implementation, the floor slab assembly is poured and stacked on the ground.

[0011] In this application, the floor slab assembly is poured and stacked on the ground, allowing the main assembly work to be carried out at ground level, reducing the amount of work at height, lowering safety risks for construction workers, and improving assembly accuracy and quality. Pouring and assembling the floor slabs on the ground also supports the use of more efficient construction equipment and processes, such as mechanized pouring and standardized formwork, thereby accelerating construction progress and shortening the overall construction period. Furthermore, ground-based operations avoid the impact of adverse weather or high-altitude environments on assembly quality, ensuring the uniformity and strength of the concrete floor slabs and improving the overall performance of the structure. Stacked assembly also optimizes space utilization, reduces construction site occupation, and is suitable for engineering scenarios with limited space.

[0012] In one alternative implementation, the vertical projection positions of the floor slabs within the floor slab group are opposite.

[0013] In this application, the vertical projection positions of the floor slabs within the floor slab assembly are opposite. This ensures that the floor slabs of each floor maintain precise alignment during lifting and installation, improving the overall integrity and stability of the structure. By having the vertical projection positions opposite each other, the floor slabs can accurately align with their installation positions during installation, avoiding adjustments and corrections during the installation process and reducing construction errors and wasted time. This alignment method also optimizes the load transfer path, ensuring uniform stress distribution on the hanging columns and connection points, preventing localized stress concentration and structural deformation, and reducing the risk of swaying or tilting, thus improving construction safety.

[0014] In one alternative embodiment, the end of the floor slab near the core tube shear wall is hinged to the core tube shear wall.

[0015] In this application, the end of the floor slab closest to the core tube shear wall is hinged to the core tube shear wall. This allows the floor slab to undergo minor displacement under load or temperature changes, reducing stress concentration and cracking risks caused by rigid connections, and improving the structure's adaptability and durability. The hinged design also simplifies the installation process, reduces connection complexity, and accelerates construction progress.

[0016] In one alternative implementation, a pad is provided between two adjacent floor slabs.

[0017] In this application, spacers are placed between two adjacent floor slabs to create a gap between them, preventing direct contact and frictional damage and ensuring the integrity of the concrete surface. The spacers also ensure that each floor slab maintains a certain vertical distance, facilitating sling operation and column installation, and improving construction accuracy and efficiency.

[0018] In one optional embodiment, the core tube shear wall is located inside the truss, and floor slabs are provided in the space between adjacent core tube shear walls and in the space between the core tube shear wall and the edge of the truss.

[0019] In this application, by setting floor slabs on the inner side and edge, the load can be evenly distributed, local overload and deformation can be prevented, the overall load-bearing capacity of the structure can be improved, an efficient overall lifting method can be supported, the complexity of slings and columns can be reduced, and construction efficiency can be improved.

[0020] In one alternative implementation, the top-level hanging column is connected at its top end to the lower chord node of the truss and at its bottom end to the top floor slab.

[0021] In this application, the top-level suspended column, located at the very top, connects its top end to the lower chord node of the truss and its bottom end to the top-level floor slab. This ensures robust support for the top-level floor slab, optimizes the load transfer path from the floor slab to the truss, and improves the overall stability and safety of the structure. By directly connecting to the lower chord node, the suspended column effectively disperses the top-level load, prevents localized stress concentration in the truss, and extends the structural lifespan. Furthermore, this application facilitates the installation and adjustment of the suspended column, reduces construction time, and supports a layer-by-layer descent installation process. Reliable anchor points are provided during the lifting process to ensure precise positioning of the floor slab assembly and reduce risks. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] High-span suspended steel structures, as a new type of structural system with an aesthetically pleasing and grand appearance, have been increasingly applied to urban landmark buildings. However, traditional construction methods, lacking a permanent support system on the ground floor, require the design and installation of temporary support frames. First, the first-floor beams and columns are installed on these temporary frames, followed by the installation of upper-floor beams and columns. After all floor beams and columns are installed, the floor slab is poured, and finally, the temporary support frames are removed. This method has several drawbacks: the temporary support frames consume additional steel and extend construction time; additional measures are needed to ensure their safety; they occupy significant construction space, potentially leaving insufficient space for steel installation when space is limited, and hindering vehicle and equipment access; and the high-altitude hoisting of the steel structure can negatively impact assembly quality.

[0027] The following is combined Figures 1 to 4 The following describes embodiments of the present invention.

[0028] According to embodiments of the present invention, such as Figure 1 As shown, a suspended steel structure integral lifting construction structure is provided, including: There are several core tube shear walls 2, each with several installation positions along its extension direction; the core tube shear walls 2 can support the truss 1. The installation positions are the design elevation positions of each floor slab 4 on the floor slab assembly.

[0029] Truss 1 is located at the top of the core tube shear wall 2; the truss 1 can be a giant truss 1 located at the top of the core tube shear wall 2.

[0030] The sling 5 is located on one side of the core tube shear wall 2 and is detachably mounted on the truss 1; The floor slab assembly includes several stacked floor slabs 4, and the suspension cable 5 is detachably connected to the bottom floor slab 4-1; it should be noted that the floor slab assembly also includes floor beams.

[0031] Among them, such as Figure 3 As shown, the sling 5 is suitable for lifting the floor slab assembly to the installation position opposite to the top floor slab 4-2, and also suitable for lowering the floor slab assembly layer by layer to the installation position corresponding to each floor slab 4. The end of the floor slab 4 closest to the core tube shear wall 2 is connected to the core tube shear wall 2. For example, after the top floor slab 4-2 is installed, the sling 5 can be lowered to install the next floor slab 4-3 in its installation position. The installation positions on the core tube shear wall 2 can be equidistantly arranged. At the installation position, the floor slab 4 can be connected to the side wall of the core tube shear wall 2. The number of installation positions corresponds one-to-one with the number of floor slabs 4. After completing the installation of all floor slab assemblies using the above steps, the sling 5 is then disassembled.

[0032] Also includes: Hanging columns 3 are installed between two adjacent floor slabs 4 at their installation positions. It is important to note that each floor slab 4 must be installed first, followed by the hanging columns 3. Specifically, after installing the top floor slab 4-2, the top-level hanging column 3-1 between the top floor slab 4-2 and the truss 1 can be installed. Then, for each subsequent floor slab 4, the hanging columns 3 between the floor slabs 4 are installed. Figure 4 As shown, for example, after installing the top floor slab 4 and the top floor hanging column 3-1, the next floor slab 4-3 can be installed, followed by the next floor hanging column 3-2 corresponding to the next floor slab 4-3. This process continues until the bottom floor slab 4-1 and its corresponding hanging column 3 are installed.

[0033] In this application, sling 5 is used to lift the floor slab assembly as a whole and lower it layer by layer, which avoids the use of temporary support frames in traditional construction, thereby saving a lot of extra steel consumption, reducing construction costs, and eliminating the safety hazards caused by temporary supports, thus improving the overall construction safety. Secondly, by lifting the floor slab assembly to the design elevation, i.e., the installation position, in one go using sling 5, and then lowering it layer by layer for installation, the amount of high-altitude hoisting work is reduced, construction risks are lowered, and the installation speed of the floor slab assembly is increased.

[0034] In one optional embodiment, one end of the suspension cable 5 is located at the lower chord node of the truss 1. The floor slab assembly is horizontally arranged, and suspension cables 5 are provided at both ends of the floor slab assembly. If the length of the floor slab assembly is relatively long, several suspension cables 5 can be provided at intervals in the middle of the floor slab assembly. The top ends of the suspension cables 5 are all located on the truss 1.

[0035] In this application, placing the sling 5 at the lower chord node effectively disperses concentrated stress generated during hoisting, preventing local deformation or damage to the truss 1 and extending the service life of the structure. Furthermore, it facilitates the installation and adjustment of the sling 5, reducing construction complexity and improving operational efficiency. Placing the sling 5 at the lower chord node maintains the balance of the floor slab assembly during lifting, preventing tilting or swaying and ensuring precise positioning of the floor slab assembly at the design elevation.

[0036] In one alternative implementation, the other end of the sling 5 is connected to the lower flange of the bottom floor slab 4-1.

[0037] In this application, as Figure 2As shown, floor slabs 4 can be stacked at the ground level. The other end of the sling 5 is connected to the lower flange of the bottom floor slab 4-1, ensuring a uniform distribution of lifting force and preventing damage caused by local stress concentration in the floor slab 4. This allows the floor slab assembly to rise and fall stably as a whole, reducing the risk of structural deformation. Furthermore, connecting the sling 5 to the lower flange of the bottom floor slab 4-1 allows for layer-by-layer descent and installation. Floor slabs 4 at the upper level can be installed first, followed by those at the lower level, reducing construction time.

[0038] In one alternative implementation, the floor slab assembly is poured and stacked on the ground.

[0039] In this application, the floor slab assembly is poured and stacked on the ground, allowing the main assembly work to be carried out at ground level, reducing the amount of work at height, lowering safety risks for construction workers, and improving assembly accuracy and quality. Pouring and assembling the floor slab 4 on the ground also supports the use of more efficient construction equipment and processes, such as mechanized pouring and standardized formwork, thereby accelerating construction progress and shortening the overall construction period. Furthermore, ground-based operations avoid the impact of adverse weather or high-altitude environments on assembly quality, ensuring the uniformity and strength of the concrete floor slab 4 and improving the overall performance of the structure. Stacked assembly also optimizes space utilization, reduces construction site occupation, and is suitable for engineering scenarios with limited space.

[0040] In one optional implementation, the vertical projection positions of the floor slabs 4 within the floor slab assembly are opposite. Specifically, the floor beams of each floor are stacked and assembled on the ground according to the corresponding positions of the vertical projection of the structure after construction, and then the concrete floor slabs 4 of each floor are poured.

[0041] In this application, the vertical projection positions of the floor slabs 4 within the floor slab assembly are opposite. This ensures that the floor slabs 4 of each floor maintain precise alignment during lifting and installation, improving the overall integrity and stability of the structure. By having the vertical projection positions opposite each other, the floor slabs 4 can accurately correspond to the installation positions during installation, avoiding adjustments and corrections during the installation process, reducing construction errors and wasted time. This alignment method also optimizes the load transfer path, ensuring uniform stress on the hanging columns 3 and connection points, preventing local stress concentration and structural deformation, and reducing the risk of swaying or tilting, thus improving construction safety.

[0042] In one alternative embodiment, the end of the floor slab 4 near the core tube shear wall 2 is hinged to the core tube shear wall 2.

[0043] In this application, the end of the floor slab 4 closest to the core tube shear wall 2 is hinged to the core tube shear wall 2. This allows the floor slab 4 to undergo slight displacement under load or temperature changes, reducing stress concentration and cracking risks caused by rigid connections, and improving the adaptability and durability of the structure. The hinged design also simplifies the installation process, reduces connection complexity, and accelerates construction progress.

[0044] In one alternative embodiment, a spacer 6 is provided between two adjacent floor slabs 4. The spacer 6 can be provided between each floor slab 4 after the concrete of the floor slabs 4 has hardened.

[0045] In this application, a spacer block 6 is provided between two adjacent floor slabs 4, so that the two adjacent floor slabs 4 have a certain distance in the vertical direction, which can prevent direct contact and friction damage between the floor slabs 4 and ensure the integrity of the concrete surface. The spacer block 6 also ensures that the floor slabs 4 of each floor maintain a certain distance in the vertical direction, which facilitates the operation of the slings 5 ​​and the installation of the hanging columns 3, and improves the construction accuracy and efficiency.

[0046] In one optional embodiment, the core tube shear wall 2 is located inside the truss 1, and floor slabs are provided in the spaces between adjacent core tube shear walls 2 and between the core tube shear wall 2 and the edge of the truss 1. The floor slabs 4 located between the core tube shear walls 2 are relatively long, with both ends hinged to the core tube shear wall 2, and several suspension cables 5 are spaced apart in the middle. Suspension columns 3 are provided between each floor slab 4. The floor slabs 4 located between the edge of the core tube shear wall 2 and the truss 1 are relatively short, with one end connected to the core tube shear wall 2 and the other end connected to the suspension column 3, and suspension cables 5 are threaded through both ends of the floor slabs 4.

[0047] In this application, by setting floor slabs on the inner side and edge, the load can be evenly distributed, local overload and deformation can be prevented, the overall load-bearing capacity of the structure can be improved, an efficient overall lifting method can be supported, the complexity of the slings 5 ​​and the columns 3 can be reduced, and the construction efficiency can be improved.

[0048] In one alternative implementation, the top-level hanging column 3-1, located at the top layer, is connected at its top end to the lower chord node of the truss 1 and at its bottom end to the top-level floor slab 4-2.

[0049] In this application, the top-level hanging column 3-1, located at the very top, is connected at its top end to the lower chord node of truss 1 and at its bottom end to the top-level floor slab 4-2. This ensures the robust support of the top-level floor slab 4, optimizes the load transfer path from floor slab 4 to truss 1, and improves the overall stability and safety of the structure. By directly connecting to the lower chord node, hanging column 3 can effectively distribute the top-level load, prevent local stress concentration in truss 1, and extend the structural lifespan. Furthermore, this application facilitates the installation and adjustment of hanging column 3, reduces construction time, and supports a layer-by-layer descent installation process. It provides reliable anchor points during the lifting process, ensuring precise positioning of the floor slab assembly and reducing risks.

[0050] This application can be applied to the construction of high-level suspended large-span steel structures, and has the following advantages: 1. This application enables the construction process of high-level suspended large-span steel structures to be completed without the need to erect temporary support frames, thereby saving a large amount of extra steel, shortening construction time, eliminating the need to consider the safety of temporary support frames, and saving construction site space. 2. This application enables the assembly of large-span steel structures suspended at high positions to be completed mainly on the ground, thereby reducing the amount of high-altitude hoisting work and improving the quality and speed of steel structure assembly; 3.
