Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of modular buildings, and particularly relates to a hybrid modular building system. Background Art
[0002] Modular buildings are an advanced stage of the development of building industrialization, which are highly integrated prefabricated buildings. They are modular units prefabricated in a factory by dividing traditional buildings according to building functions. The connection nodes between modules have a significant impact on the overall performance of the structure, so their design is crucial. According to the different main lateral force resisting systems, modular buildings can be divided into fully modular systems and composite modular systems. The fully modular system is a modular structural form similar to a box, also known as box building. This modular system is entirely assembled by modular units, mainly a semi-rigid connection system. The connection force is not clear, and existing calculation programs do not cover it, so it cannot be directly designed and analyzed using existing programs. Moreover, since it is difficult to achieve rigid connections in vertical connections, the vertical lateral force resisting connections are weak, and it is generally applicable to buildings with regular planes not exceeding 18 floors, such as hotels and apartments.
[0003] Such as Figure 1 , the composite modular system generally uses a traditional structural system such as a frame structural system as the external skeleton of the building, installs modular units inside the traditional structure on each floor, and rigid connections can be achieved in vertical connections, which can give full play to the advantages of the traditional structural system to meet the lateral force resisting requirements, thereby increasing the building height and being applicable to more irregular buildings. However, the stiffness of the modular building cannot be fully utilized during use, resulting in waste; due to the inability to fully utilize the force of the modular building, the external skeleton structural system needs to be made larger, causing waste of structural materials; compared with the traditional structural system, the number of construction for the external skeleton structural system has not decreased, and the construction efficiency is low.
[0004] The current modular building systems have the following problems. First, the connection nodes of the fully modular system are mainly semi-rigid connections, and rigid connections cannot be achieved. The vertical lateral force resisting connections are weak and cannot be applied to buildings with higher heights. The connection force of the semi-rigid connection system is not clear, and existing calculation programs do not cover it, so it cannot be directly designed and analyzed using existing programs. Second, the stiffness of the modular building in the composite modular system cannot be fully utilized during use, resulting in waste; due to the inability to fully utilize the force of the modular building, the external skeleton structural system needs to be made larger, causing waste of structural materials; compared with the traditional structural system, the number of construction for the external skeleton structural system has not decreased, and the construction efficiency is low. Third, due to the limitations of the transportation conditions of modular buildings, the module structure size is limited, and it often cannot meet the requirements of irregular building shapes, large spans, and partial non-standardization.
[0005] The present invention proposes a new solution to address the above problems. Summary of the Invention
[0006] In view of the above problems existing in the existing modular building system, the object of the present invention is to provide a new type of hybrid modular building system. By adopting a hybrid of a modular structure layer and a traditional structure layer, the building modules are prefabricated, and the force-bearing members of the traditional structure layer between the building modules are rigidly connected and constructed on-site. In the building system with such a structure, the floor slabs at the joints between the lower modules and the upper modules are no longer repeated, the beams between the lower modules and the upper modules are no longer repeated, and the vertical members such as columns or shear walls between the front and rear modules are no longer repeated.
[0007] To achieve the above object, the hybrid modular building system provided by the present invention includes a number of prefabricated modules, a number of first traditional structure layers, and a number of second traditional structure layers;
[0008] The number of prefabricated modules are arranged in sequence horizontally and vertically. The opposite sides between horizontally adjacent prefabricated modules are connected by a first traditional structure layer, and the opposite top or bottom surfaces between vertically adjacent prefabricated modules are connected by a second traditional structure layer;
[0009] The first traditional structure layer is internally provided with traditional horizontal force-bearing members, the second traditional structure layer is internally provided with traditional vertical force-bearing members, and the prefabricated module is internally provided with horizontal internal skeletons and vertical internal skeletons corresponding to the traditional horizontal force-bearing members and traditional vertical force-bearing members. The traditional horizontal force-bearing members are rigidly connected to the horizontal internal skeletons, and the traditional vertical force-bearing members are rigidly connected to the vertical internal skeletons to realize the connection and fixation of horizontally adjacent prefabricated modules and vertically adjacent prefabricated modules.
[0010] Further, the first traditional structure layer and the second traditional structure layer can be shear walls, beams, columns or trusses.
[0011] Further, the internal skeletons in the first traditional structure layer, the second traditional structure layer and the prefabricated module are designed synchronously, and the lengths of the traditional horizontal force-bearing members and traditional vertical force-bearing members in the first traditional structure layer and the second traditional structure layer can be changed arbitrarily.
[0012] Further, the prefabricated module is internally provided with a number of horizontal internal skeletons and a number of vertical internal skeletons, and the number of horizontal internal skeletons are arranged horizontally in sequence and are arranged at the corners of the prefabricated module, and the vertical internal skeletons are arranged vertically in sequence and are arranged at the corners of the prefabricated module.
[0013] Further, the number of traditional horizontal force-bearing members in the first traditional structure layer are arranged horizontally in sequence and are arranged at the corners of the first traditional structure layer;
[0014] The number of traditional vertical force-bearing members in the second traditional structure layer are arranged vertically in sequence and are arranged at the corners of the second traditional structure layer.
[0015] Furthermore, the horizontal internal skeleton intersects the vertical internal skeleton perpendicularly, and stiffeners are provided between the horizontal internal skeleton and the vertical internal skeleton.
[0016] Compared with the prior art, the hybrid modular building system provided by the present invention has the following beneficial effects:
[0017] (1) The force-bearing members of the traditional structural layer are used between precast modules to achieve rigid connection through traditional methods such as welding, bolting, and in-situ casting during on-site construction, which can provide greater lateral stiffness and can adapt to higher buildings such as high-rise buildings;
[0018] (2) The connection between the module and the traditional structural layer can be carried out in a traditional manner, with clear force-bearing, and the rigid connection is covered in the existing calculation programs, so the existing calculation programs can be directly used for design and calculation; the connection construction can utilize the existing mature experience, and the quality installation is reliable and convenient.
[0019] (3) The internal skeleton structure of the module and the traditional force-bearing members in this solution can be used as lateral force-resistant members, and the stiffness can be fully utilized during use. The cross-sectional materials are fully utilized to the greatest extent. The beams, floors, etc. of the structural system are no longer repeated, the stiffness is maximally utilized, materials are saved, and waste is reduced;
[0020] (4) Since the sizes of the horizontal and vertical members of the traditional structural layer are variable and are no longer limited by the irregularity of the building size, the building adaptability of this structure is increased, and it can meet the requirements of irregular building shapes, large spans, and partial non-standardization, etc.
[0021] (5) During the construction process, compared with the traditional composite modular system, the number of on-site construction required can be reduced by nearly 50%; the modular building layer acts as an enclosure system and a floor during the construction process, reducing the temporary construction measures, facilitating construction, and also facilitating the cross-construction of decoration, mechanical and electrical installation, etc., effectively improving the construction efficiency.

[0032] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.
[0033] Refer to Figures 4 - 6 , which shows the structural schematic diagram of the hybrid modular building system provided by the present invention.
[0034] According to the illustration, it can be known that the hybrid modular building system provided by the present invention includes three components: a number of precast modules 110, a number of first traditional structural layers 120, and a number of second traditional structural layers 130.
[0035] Among them, a number of precast modules 110 are arranged horizontally and vertically in sequence. The opposite side surfaces between horizontally adjacent precast modules 110 are connected by the first traditional structural layer 120, and the opposite top or bottom surfaces between vertically adjacent precast modules 110 are connected by the second traditional structural layer 200;
[0036] The first traditional structural layer 120 is internally provided with a traditional horizontal load-bearing member 121, the second traditional structural layer 130 is internally provided with a traditional vertical load-bearing member 131, and the precast module 110 is internally provided with a horizontal internal skeleton 111a and a vertical internal skeleton 111b corresponding to the traditional horizontal load-bearing member 121 and the traditional vertical load-bearing member 122. The traditional horizontal load-bearing member 121 is rigidly connected to the horizontal internal skeleton 111a, and the traditional vertical load-bearing member 131 is rigidly connected to the vertical internal skeleton 111b to realize the connection and fixation of horizontally adjacent precast modules 110 and vertically adjacent precast modules 110.
[0037] Compared with the prior art, this solution adopts a hybrid of modular structure and traditional structure. The prefabricated module 110 is prefabricated, and the prefabricated modules 110 are rigidly connected through welding, bolting, in-situ casting, etc. with the traditional structure layer between them and constructed on-site. In the building system with such a structure, the floor slabs at the joints between the lower and upper building layers are no longer repeated, the beams between the lower and upper building layers are no longer repeated, and the columns between the front and rear building layers are no longer repeated, reducing waste.
[0038] Specifically, as Figure 4 , which is a schematic diagram of the assembled effect of the hybrid modular building system. The storey height, the number of transverse spans, and the number of longitudinal spans can all be designed according to the current structural design specifications. The prefabricated module 110 can be designed and prefabricated according to the current specifications. The prefabricated modules 110 are connected on-site through the first traditional structure layer 120 and the second traditional structure layer 130. The first traditional structure layer 120 and the second traditional structure layer 130 are designed according to the current structural design specifications according to the structural system adopted by the entire building, and can be in the forms of shear walls, beams, columns, trusses, etc.
[0039] Furthermore, the internal skeletons in the first traditional structure layer 120, the second traditional structure layer 130, and the prefabricated module 110 are designed synchronously, and the lengths of the traditional horizontal load-bearing members 121 and the traditional vertical load-bearing members 131 in the first traditional structure layer 120 and the second traditional structure layer 130 can be arbitrarily changed and according to the design requirements. Since the sizes of the traditional horizontal load-bearing members 121 and the traditional vertical load-bearing members 131 are variable, the overall building system is no longer limited by the fixed building size, increasing the adaptability of this structure to buildings.
[0040] Furthermore, several prefabricated modules 110 can be rectangular modules, or can be other shaped modules according to the building needs;
[0041] In order to further improve the reliability of the connection, as Figure 5 , Figure 6 , several horizontal internal skeletons 111a and several vertical internal skeletons 111b are provided inside the prefabricated module 110, and the several horizontal internal skeletons 111a are arranged horizontally in sequence and are arranged at the corners of the prefabricated module 110, and the vertical internal skeletons 111b are arranged vertically in sequence and are arranged at the corners of the prefabricated module 110.
[0042] Correspondingly, several traditional horizontal load-bearing members 121 in the first traditional structure layer 120 are arranged horizontally in sequence and are arranged at the corners of the first traditional structure layer 120.
[0043] Several traditional vertical load-bearing members 131 in the second traditional structure layer 130 are arranged vertically in sequence and are arranged at the corners of the second traditional structure layer 130. This greatly improves the reliability of the connection.
[0044] Furthermore, the horizontal internal skeleton 111a intersects the vertical internal skeleton 111b perpendicularly, and a stiffening rib 111c is provided between the horizontal internal skeleton 111a and the vertical internal skeleton 111b to further improve the structural reliability.
[0045] The connection of the existing module structure is to connect the modules with a connection structure, and the connection structure is limited to a local area. The connection of the hybrid modular building system provided in this solution uses the traditional load-bearing members of the traditional structural layer to be connected.
[0046] In this solution, by mixing the modular structure with the traditional structure, the precast module 110 is prefabricated. The precast module 110 and the precast module 110 are connected by traditional load-bearing members and constructed on-site. The connection realizes a rigid connection, which can provide greater lateral stiffness and can adapt to higher buildings such as high-rise buildings; it can be used as a lateral force-resistant member, making the most of the cross-sectional materials. The beams and floors of the structural system are no longer repeated, and the stiffness is maximally utilized, saving materials and reducing waste. Avoiding the use of additional connecting parts, the existing load-bearing members of the traditional layer can be fully utilized for connection. The precast module 110 and the traditional structural layer can be connected in a traditional way. For example, when it is a steel structure, full welding connection, bolt welding connection, bolt connection, etc. can be used; when it is a concrete structure, mechanical connection of steel bars, lap connection, welding connection, etc. can be used. During the construction process, since nearly half of the building can be precast modular buildings, the precast modular buildings can be used as the main load-bearing structure, so the number of traditional structural systems required for construction can be reduced by nearly 50%; in addition, the modular buildings act as the enclosure system and floors during the construction process, reducing the temporary construction measures, facilitating construction, and also facilitating the cross-operation of decoration, mechanical and electrical, etc.
[0047] Secondly, the connection structure between the modules of this method uses the load-bearing members of the traditional structural layer 200. The connection can adopt the traditional form and achieve a complete rigid connection, with clear force and reasonable structure. There is no need to add additional non-standard connection members not included in the software, which is convenient for calculating and analyzing the force of the skeleton load-bearing members using existing software during the design.
[0048] Thirdly, the module skeleton structure and the connection structure members of this method make the most of the cross-sectional materials. The module top plates and materials are saved, and it is very mature in the design industry. Moreover, the floors where the lower modules and the upper modules are connected are no longer repeated, the beams of the lower modules and the upper modules are no longer repeated, and the columns between the front and rear modules are no longer repeated, reducing waste.
[0049] Fourthly, since the sizes of the load-bearing members of the traditional structural layer 200 are variable and are no longer limited by the irregularity of the building size, the building adaptability of this structure is increased.
