Description

Technical Field

[0001] This invention belongs to the field of prefabricated buildings, and in particular relates to a high-rise prefabricated modular building. Background Technology

[0002] Modular building is an emerging type of prefabricated construction. Its structural system differs from traditional structural forms, as it modularizes the entire building, assembling stable modular units into a whole through inter-unit nodes. These modular units can be prefabricated in factories, from structure and piping to interior and exterior decoration, achieving integration and full factory production of architecture, structure, electromechanical systems, and decoration, with an industrialization rate of up to 85%. On-site construction only requires "building block" style overall hoisting and simple assembly, with an on-site assembly rate exceeding 90%, significantly reducing on-site workload and construction time. With its high prefabrication rate and assembly level, and significant advantages in improving project quality, shortening construction time, saving manpower and resources, and protecting the environment, modular building has gradually become a distinctive direction in industrialized construction.

[0003] In existing modular building applications, load-bearing is mainly achieved through modular unit boxes. When used in super high-rise buildings, they are often combined with a core tube. The core tube resists horizontal loads, but the self-weight is still borne by the modular units. However, due to the modular disassembly and assembly method, the internal and external dimensions of the units are limited, thus placing high demands on the dimensions of structural components. Therefore, when applied to high-rise buildings, the lower-level modular units often employ thick-walled column structures, or the modular columns encroach on the internal usable space. Furthermore, modular buildings are difficult to apply to super high-rise buildings in the 30-40 story range. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a high-rise modular building and construction method that combines a giant frame and segmented infill modules, which can expand the application of modular buildings in super high-rise buildings, while achieving efficient load-bearing capacity and maintaining the advantages of modular building in terms of unified design, lightweight, high standardization and industrialized construction.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] This invention relates to a high-rise modular building combining a megaframe and partitioned infill modules, comprising a core tube, a megaframe, and infilled modular substructures. The megaframe includes outer frame columns, connecting trusses, and a floor system. The infilled modular substructures include modular units, inter-unit connections, and unit-to-external structure connections. Connecting trusses are installed at intervals of multiple floors, connecting the outer frame columns and the core tube to form a ring-shaped truss structure. The floor system is located above or below the connecting trusses. Each partitioned modular unit is stacked on the floor system, and adjacent modular units are connected through inter-unit connections. The modular units are connected to the outer frame columns and the core tube through unit-to-external structure connections.

[0007] Furthermore, the core tube can be located in the middle of the overall building or distributed inside the building, and can be constructed using reinforced concrete, steel plate concrete or steel-concrete composite structures; the core tube has reserved openings for passage or doors and windows at corresponding positions on each floor.

[0008] Furthermore, the outer frame column is vertically continuous and can be made of single material or combined structure columns such as steel column, reinforced concrete, steel pipe concrete or embedded steel concrete.

[0009] Furthermore, the connecting truss is installed every 4-10 floors, and the height and size of the connecting truss are set according to the stress requirements.

[0010] Furthermore, the floor system may be a combination of concrete slabs or profiled steel sheets.

[0011] Furthermore, when the floor slab system uses concrete slabs, if the floor slab system is located above the connecting truss and forms a composite floor slab system with the connecting truss, the connecting truss can be used as a temporary formwork support during the construction of the floor slab system; if the floor slab system is located below the connecting truss, the filled modular units can be used as temporary formwork supports during the construction of the floor slab system, and temporary construction formwork and supports can be erected on the filled modular units for the construction of the floor slab system. After the construction of the floor slab system is completed, the temporary formwork and supports are removed.

[0012] Furthermore, the modular unit can be a light steel structure, steel frame structure, or concrete independent modular structure unit, and its construction can be a closed modular box or an open modular box; the filled modular substructures with different vertical partitions can adopt different modular unit layouts according to the usage requirements.

[0013] Furthermore, the connection between the units can be achieved by using corner connection boxes at the corners of the module units, and by connecting plates and high-strength bolts to tie adjacent corner connection boxes together, thereby connecting adjacent module units.

[0014] Furthermore, the connection between the unit and the external structure can adopt a vertical sliding groove design. Vertical sliding grooves are set on the outer frame column and the core tube, and a fixed slider is installed on the corner connection box at the corner of the module unit. It can be embedded in the vertical sliding groove to realize the vertical sliding and horizontal connection between the module unit and the outer frame column and the core tube.

[0015] This invention also provides a construction method for a high-rise modular building combining a megaframe and partitioned infill modules, comprising the following steps:

[0016] S1: Construct a vertically partitioned core tube;

[0017] S2: Construct the outer frame column of a vertical partition;

[0018] S3: Modular units are filled layer by layer within a vertical partition. Inter-unit connections are used to link adjacent modular units, and unit connections are used to link the modular units to the outer frame columns and core tube. Trusses are connected according to the design and construction specifications.

[0019] S4: When constructing a vertically partitioned infilled modular substructure, the core tube of the previous vertical partition is constructed simultaneously.

[0020] S5: Construct and install the floor slab system, and simultaneously construct and install the outer frame columns of the next vertical section;

[0021] S6: Repeat steps S3-S5 until the core tube and outer frame columns of the last vertical section are installed;

[0022] S7: Fill the last vertical partition with module units layer by layer, connect adjacent module units with inter-unit connections, and connect module units with external structures to connect module units with outer frame columns and core tubes.

[0023] S8: Construction of the top slab of the high-rise building is complete.

[0024] Compared with existing technologies, this invention has the following advantages: The modular structure of this high-rise modular building is partitioned, with modular units in each partition stacked on the floor slab system in a filling manner. The modular units are interconnected to form independent modular substructures. Different partitions can adopt different layouts, quantities, and structural forms of modular units according to functional requirements. The load of the modular substructure in each partition is transferred to the connecting trusses through the floor slab system, and further transferred to the outer frame columns and core tube. Therefore, the modular substructure within a partition only needs to bear its own weight load. The modular units can adopt standardized and lightweight designs. This invention enables the application of lightweight and standardized modular units in ultra-high-rise modular buildings, and the modular building layout can be changed according to requirements in different partitions. This invention uses a combination of a mega-frame and a core tube structure, which can fully utilize the load-bearing and construction advantages of different types of buildings. During construction, the core tube can be used as a fulcrum for the hoisting of modular units, and the infilled modular substructures or connecting trusses can be used as temporary supports during the construction of each floor slab system. The overall high-rise building construction process does not require additional scaffolding or other supporting structures, making the construction process simple and fast.

[0035] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0036] Reference Figures 1 to 9 A high-rise modular building combining a megaframe and partitioned infill modules includes a core tube 1, a megaframe, and infilled modular substructures. The megaframe includes outer frame columns 2, connecting trusses 4, and a floor system 6. The infilled modular substructures include modular units 3, inter-unit connections 5, and unit-to-external structure connections 7. The connecting trusses 4 are arranged at intervals of multiple layers, and the connecting trusses 4 connect each outer frame column 2 and the core tube 1 to form a ring-shaped truss structure. The floor system 6 is located above or below the connecting trusses 4. Each partitioned modular unit 3 is stacked on the floor system 6. Adjacent modular units 3 are connected by inter-unit connections 5, and modular units 3 are connected to the outer frame columns 2 and the core tube 1 by unit-to-external structure connections 7.

[0037] In this embodiment, the core tube 1 is located in the middle of the overall building, but it can also be distributed inside the building; the core tube 1 adopts a reinforced concrete structure, but it can also adopt a steel plate concrete or steel-concrete composite structure; the core tube 1 has reserved holes 11 for passage or doors and windows at corresponding positions on each floor.

[0038] In this embodiment, the outer frame column 2 is vertically continuous and is a steel column structure column. Of course, it can also be a single material or a combination of structural columns such as reinforced concrete, steel pipe concrete or embedded steel concrete.

The floor slab system 6 is located above the connecting truss 4, forming a combined floor slab system with the connecting truss 4. During construction, the connecting truss 4 can serve as a temporary formwork support. If the floor slab system 6 is located below the connecting truss 4, the already filled module units 3 can serve as temporary formwork supports during construction. Temporary construction formwork and supports 13 are erected on the filled module units 3 for floor slab system 6 construction. After the floor slab system 6 construction is completed, the temporary formwork and supports 13 are removed.

[0041] In this embodiment, the module unit 3 can be a lightweight steel structure, a steel frame structure, or a concrete independent modular structure unit. Its construction can be a closed modular box or an open modular box. Module units within each zone are stacked and arranged. Different vertical zones can use module units 3 of the same specifications and sequence to form a fully-filled modular building according to usage requirements. Alternatively, adjacent or spaced zones can use a combination or staggered arrangement of mixed rectangular module units or large-span square module units 31. The construction, size, and layout of the module units 3 in different upper and lower zones can be configured differently according to the building's usage requirements.

[0042] In this embodiment, the inter-unit connection 5 adopts a corner connection box 8 set at the corner of the module unit 3, and the adjacent corner connection boxes 8 are connected by a connecting plate 9 and a high-strength bolt 10, thereby connecting the adjacent module units 3.

[0043] In this embodiment, the connection between the unit and the external structure 7 adopts a vertical sliding groove design. Vertical sliding grooves 12 are pre-embedded or fixed on the outer frame column 2 and the core tube 1. An embedded slider 14 is installed on the corner connection box 8 at the corner of the module unit 3, which can be embedded in the vertical sliding groove 12, so as to realize the vertical sliding and horizontal connection between the module unit 3 and the outer frame column 2 and the core tube 1.

[0046] S2: Construct an outer frame column 2 for a vertical partition;

[0047] S3: In a vertical partition, fill the module unit 3 layer by layer, use the inter-unit connection 5 to connect adjacent module units 3, and use the unit to external structure connection 7 to connect module unit 3 to outer frame column 2 and core tube 1; according to the design and construction connection truss 4;

[0052] First, the module unit 3 adjacent to the outer frame column 2 and the core tube 1 is hoisted and slid in. Then, other module units 3 are filled in layer by layer. The corner connection boxes 8 of the adjacent module units 3 are connected layer by layer by the inter-unit connection 5.

[0053] S8: Construction of the top slab of the building is complete (61 meters). The construction of the high-rise building is now finished.

[0054] Finally, it should be noted that although the technical solutions of the present invention have been described above in conjunction with the accompanying drawings and embodiments, the present invention is not limited to the above embodiments. The above embodiments are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims, and these all fall within the scope of protection of the present invention.
