Description

Technical Field

[0001] The present application belongs to the field of construction engineering technology, and in particular relates to a reconfigurable steel structure assembled building system. Background Art

[0002] As the global, especially China, requirements for low-cost, high-speed and green sustainable construction continue to increase, prefabricated buildings are increasingly valued by the global construction industry. However, most of the existing prefabricated buildings have low productization and component commonality, long processing cycles, low precision, and require higher and more professional technical personnel from the design end. As a result, the delivery speed has not been improved, and the cost is generally higher than that of traditional buildings, which greatly limits their widespread promotion and application.

[0003] First, the commonality of each building unit and component of traditional prefabricated buildings is extremely low, especially the core part related to building safety - beams, columns, connectors, etc. in the structure are designed into various forms of components and connection methods. A large number of non-standard and customized components result in: 1) long design cycle and complex production process; 2) the installation process requires professionals to mark, identify and sort the components on site, which makes on-site management complicated; 3) preliminary training is required before each installation and professionals are needed during the construction process; 4) the comprehensive building installation time is extended and the cost is increased. It is completely impossible to meet the expectations and requirements for high-speed and low-cost delivery of prefabricated buildings; 5) non-standard components cannot be effectively stocked in advance, which also creates a huge obstacle to rapid delivery.

[0004] Second, existing prefabricated buildings, especially steel structure prefabricated buildings, still need to rely on a large number of on-site welding operations, especially during the installation of complex connection nodes. Welding not only requires professional and technical workers to operate, but also due to the uncertainty of the on-site environment, the welding quality is often difficult to control, and welding errors or quality problems are very likely to occur. This not only increases the uncertainty in the construction process, but also lengthens the construction period, further increasing labor costs and total project costs.

[0005] Third, the non-standard customized components of traditional prefabricated buildings lack versatility, resulting in poor reconfigurability of the building and failure to achieve high green sustainability. When a building needs to be rebuilt, expanded, or demolished and rebuilt in a different location, it must be redesigned, produced, and installed. After demolition, most materials and components cannot be reused, resulting in a huge waste of resources and a huge amount of solid waste that is difficult to handle. Customizing new connection nodes leads to unnecessary time delays and high costs.

[0006] These technical defects and management difficulties make the promotion and popularization of existing prefabricated buildings face huge challenges, especially in the context of high labor costs and increasing requirements for green buildings, traditional prefabricated building technology cannot adapt to the higher requirements of the social environment and the market.

[0007] In order to solve these problems, there is an urgent need for a new prefabricated construction technology that can design and produce universal building units and components based on the basic logic of productization. It can not only support and meet the needs of various building functions and scenarios, but also be fast to produce, deliver and install, with high quality and safety and controllable costs.

[0065] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0066] It should be noted that when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a centrally arranged element at the same time. When an element is considered to be "set" on another element, it may be directly set on the other element or there may be a centrally arranged element at the same time. In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, or it can be internal communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0067] In the description of the embodiments of the present application, the technical terms "first", "second", etc. are only used to distinguish different objects, and cannot be understood as indicating or implying relative importance or implicitly indicating the number, specific order or primary and secondary relationship of the indicated technical features. In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0068] In the description of the embodiments of the present application, the term "vertical" is used to describe an ideal state between two components. In actual production or use, there may be a state approximately perpendicular between the two components. For example, in combination with numerical descriptions, perpendicularity may refer to the angle between two straight lines being between 90±10°, perpendicularity may also refer to the dihedral angle between two planes being between 90°±10°, and perpendicularity may also refer to the angle between a straight line and a plane being between 90±10°.

[0069] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. The various embodiments in the present application may be combined with each other in the absence of conflict.

[0070] It should be noted that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device are only exemplary and should not constitute any limitation to the present application.

[0071] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0072] like Figures 1 to 3 As shown, the embodiment of the present application provides a reconfigurable steel structure prefabricated building system 100, including at least one building unit 10. It is understandable that the reconfigurable steel structure prefabricated building system 100 may include only one building unit 10, or may include multiple building units 10. When the reconfigurable steel structure prefabricated building system 100 includes multiple building units 10, the multiple building units 10 are detachably connected together to facilitate installation and disassembly at the construction site. In addition, by disassembling the building system 100, the building unit 10 can be reused, reducing the waste of resources, thereby effectively improving the sustainability and environmental protection of the building system.

[0073] In one embodiment, the building unit 10 includes a connector 11, at least one beam 12 and at least one column 13, and the at least one beam 12 and the at least one column 13 are both detachably connected to the connector 11. Specifically, the connector 11 includes four side walls and two end walls 115, and the four side walls are connected in sequence. The two end walls 115 are arranged along the first direction X and are connected to the four side walls. Among them, the side wall is used to connect the beam 12, and the end wall 115 is used to connect the column 13. The first direction X can be the length direction of the connector 11. Through this structure, the design of the connector 11 provides a high degree of flexibility and modularity, making the traditional prefabricated building extremely simple and convenient for the drop-plate design and construction required for the indoor wet area in the building structure and the height difference between the balcony and the interior, so as to meet the needs of various building layouts.

[0074] In one embodiment, any one of the at least one beam 12 is detachably connected to a side wall, and any one of the at least one column 13 is detachably connected to an end wall 115, so that the building unit 10 is a detachable device. At the construction site, the beams 12 and the columns 13 can be detachably connected to the connector 11 by using relevant tools, so that the building unit 10 is a reconfigurable structure. Further, by detachably connecting multiple building units 10 together, a reconfigurable steel structure assembled building system 100 can be obtained, and by increasing or decreasing the number of building units 10, or adjusting the assembly position of the building units 10, the building system 100 can be flexibly constructed, which is conducive to reducing the manufacturing cost of the building system 100 and adapting to the rapid changes in different building scales and needs.

[0075] In the reconfigurable steel structure assembly building system 100, the same connector 11 can be applied to connection joints in various scenarios, so that the building system 100 requires fewer types of parts and has many advantages. Specifically:

[0076] On the design side, fewer types of parts enable designers to quickly design based on standardized parts, reducing the time and labor costs of design, while avoiding customized design of multiple parts, greatly saving design costs.

[0077] On the production side, reducing the number of parts enables the production line to achieve efficient mass production, reduces resource waste in the production process, greatly improves production efficiency, and reduces production costs.

[0078] On the warehousing side, inventory management becomes simpler due to the smaller number of parts and components, and timely delivery can be achieved through bulk stocking, reducing inventory backlogs and management difficulties.

[0079] On the assembly side, the reduced number of parts helps reduce the difficulty for construction workers to identify parts and reduces dependence on highly skilled workers. Construction workers only need simple training to get started quickly, thereby improving construction efficiency and reducing the risks of human errors.

[0080] In addition, the reconfigurable steel structure assembly building system 100 can be assembled without welding. This innovative design helps to reduce the construction difficulty of construction workers, greatly improves assembly efficiency, reduces labor costs, and reduces the adverse effects of welding errors. Through standardized connectors 11, beams 12 and columns 13, the assembly and disassembly of building units can be completed quickly, reducing technical difficulties and construction cycles that may arise during the construction process. In addition, connectors 11, beams 12 and columns 13 can all be used as standardized general parts. Through different designs and combinations, they can be used to build different building systems 100, and can be disassembled and reused, further reducing resource waste, and have significant economic value and sustainability.

[0081] In one embodiment, in a building unit 10, the number of beams 12 can be one, two, three or four, and the number of columns 13 can be one or two. Different numbers of beams 12 and columns 13 can be reconfigurable assembled and connected through a connector 11 of one specification. The connector 11 can be used as a standardized universal part and is suitable for connection joints in a variety of scenarios, which is conducive to reducing the types of connectors 11, facilitating on-site assembly, and facilitating the production and inventory management of the connectors 11.

[0082] It can be understood that the number of beams 12 and columns 13 in a building unit 10 can be determined according to the position of the building unit 10 in the building system 100. For example, when the building unit 10 is located at the top or bottom floor of the building system 100, the number of columns 13 can be one. For example, when the building unit 10 is located in the middle area of ​​the building system 100, the number of beams 12 can be four, and the number of columns 13 can be two. For example, when the building unit 10 is located at the edge of the building system 100, the number of beams 12 can be two or three.

[0083] In one embodiment, among the two building units 10 connected to each other, the cross beam 12 of one building unit 10 is connected to the side wall of the connector 11 of the other building unit 10. Among the two building units 10 connected to each other, the column 13 of one building unit 10 is connected to the end wall 115 of the connector 11 of the other building unit 10.

[0084] like Figures 2 to 4As shown, in one embodiment, each side wall is provided with a first hole 1161, and each crossbeam 12 is provided with a second hole 121. In the interconnected side walls and crossbeams 12, the first hole 1161 on the side wall and the second hole 121 on the crossbeam 12 are interconnected and butted. The reconfigurable steel structure assembled building system 100 also includes a first connecting component (not shown), at least part of which penetrates the first hole 1161 and the second hole 121, and fixedly connects the side wall and the crossbeam 12. The first connecting component penetrates the first hole 1161 and the second hole 121 that are butted against each other, thereby detachably fixing and connecting the side wall and the crossbeam 12. The assembly process does not require welding, which is conducive to reducing the difficulty of on-site construction, reducing the skill requirements for construction personnel, and improving assembly efficiency. The positioning of the crossbeam 12 and the connector 11 is achieved through the cooperation between the first hole 1161 and the second hole 121, which is conducive to improving the dimensional accuracy of the reconfigurable steel structure assembled building system 100. Furthermore, by disassembling the first connecting component, the building system 100 can be disassembled, thereby realizing the reconfiguration of the building system 100 and the reuse of components.

[0085] In one embodiment, the second hole 121 is a through hole, the first hole 1161 is a threaded hole, and the first connection assembly may include a first bolt, which passes through the second hole 121 and then into the first hole 1161, and is threadedly connected with the first hole 1161.

[0086] In one embodiment, the first hole 1161 and the second hole 121 are both through holes, and the first connection assembly may include a first bolt and a first nut, and the first bolt passes through the first hole 1161 and the second hole 121 that are connected to each other and then is locked and connected with the first nut. This connection method is simple and reliable, and the difficulty of assembly and disassembly is relatively low, which is conducive to improving assembly or disassembly efficiency.

[0087] In one embodiment, when the first hole 1161 and the second hole 121 are both through holes, the first connection assembly may include a latch or a pin piece, which is inserted into the first hole 1161 and the second hole 121 to fix the side wall and the crossbeam 12. This connection method is simple and reliable, and the difficulty of assembly and disassembly is relatively low, which is conducive to improving assembly or disassembly efficiency.

[0088] In one embodiment, a plurality of first holes 1161 are arranged on the same side wall, and the plurality of first holes 1161 are arranged in an array along the first direction X. In the interconnected side walls and beams 12, by moving the beams 12 relative to the connectors 11 along the first direction X, the second holes 121 are docked with different first holes 1161, and then fixedly connected by the first connecting assembly, the position adjustment along the first direction X relative to the connectors 11 can be achieved, so as to meet different construction and assembly requirements, which is conducive to improving the diversity of the reconfigurable steel structure assembly building system 100. In addition, it is also conducive to reducing the specifications of the connectors 11 and the number of parts in the building system 100.

[0089] In one embodiment, a plurality of second holes 121 are provided on the same beam 12, and the plurality of second holes 121 are arranged in an array along the first direction X.

[0090] In one embodiment, a plurality of first holes 1161 are arranged on the same side wall, and the plurality of first holes 1161 are arranged along the first direction X. A plurality of second holes 121 are arranged on the same crossbeam 12, and the plurality of second holes 121 are arranged along the first direction X. In addition, along the first direction X, the hole spacing between two adjacent first holes 1161 and the hole spacing between two adjacent second holes 121 are equal. In the interconnected side wall and crossbeam 12, by moving the crossbeam 12 relative to the connector 11 along the first direction X, and making different first holes 1161 and different second holes 121 docked, and then fixedly connected by the first connecting assembly, the position adjustment along the first direction X relative to the connector 11 can be achieved, so as to meet different construction and assembly requirements, which is conducive to improving the diversity of the reconfigurable steel structure assembled building system 100. In addition, it is also conducive to reducing the specifications of the connector 11 and reducing the number of parts in the building system 100.

[0092] In one embodiment, each end wall 115 is provided with a third hole 1162, and each column 13 is provided with a fourth hole 131. In the end wall 115 and the column 13 connected to each other, the third hole 1162 on the end wall 115 and the fourth hole 131 on the column 13 are connected to each other and butted. The reconfigurable steel structure assembled building system 100 also includes a second connection component (not shown), which penetrates the third hole 1162 and the fourth hole 131 that are butted to each other, and fixedly connects the end wall 115 and the column 13. The second connection component penetrates the third hole 1162 and the fourth hole 131 that are butted to each other, and then the end wall 115 and the column 13 are detachably fixedly connected. The assembly process does not require welding, which is conducive to reducing the difficulty of on-site construction, and the positioning of the column 13 and the connector 11 is achieved through the cooperation between the third hole 1162 and the fourth hole 131, which is conducive to improving the dimensional accuracy of the reconfigurable steel structure assembled building system 100.

[0093] In one embodiment, one of the third hole 1162 and the fourth hole 131 is a through hole, and the other is a threaded hole. As an example, taking the third hole 1162 as a threaded hole and the fourth hole 131 as a hole position, the second connection assembly may include a second bolt, which passes through the fourth hole 131 and then into the third hole 1162, and is threadedly connected with the third hole 1162.

[0112] In summary, the reconfigurable steel structure prefabricated building system 100 of the present application provides an efficient, accurate, flexible and cost-controlled assembly solution through innovative design. The core innovation of the system is to use a standardized connector 11, and to detachably connect the beam 12 and the column 13 to the connector 11 through relevant tools, so that the building unit 10 has a reconfigurable structure. The design of this system has significant advantages, including:

[0113] 1. High-precision assembly to reduce cumulative tolerances. The welding process in traditional prefabricated building systems will lead to gradually accumulated errors, affecting the assembly accuracy of the building, especially during later expansions, which may lead to assembly mismatches. This system eliminates the error accumulation that may occur during the welding process by using a non-welded connector 11. In this way, the assembly accuracy is significantly improved, reducing the assembly errors caused by cumulative tolerances and the problems that affect the integrity and consistency of the building. Especially in later expansions and adjustments, docking and assembly can be performed accurately and efficiently to ensure the stability of the building structure and the accuracy of long-term use.

[0114] 2. High transportation efficiency and reduced transportation costs. The connector 11 and steel sections of this system adopt a simple straight-line design without complex shapes or unnecessary additional components, which greatly improves the utilization of transportation space. The parts of traditional prefabricated buildings are complex in shape and of different sizes, which often results in waste of transportation space and increases the cost and difficulty of transportation. The standardized design of this system allows the parts to be arranged more compactly, reducing space waste during transportation, improving transportation efficiency, and significantly reducing transportation costs. This design is particularly advantageous for large-scale projects and cross-regional transportation, and can reduce logistics costs and transportation cycles.

[0115] 3. Flexible expansion and strong adaptability. The connector 11 of this system is designed with the feature of six-sided connectable steel sections, making the expansion of the building more flexible. When an existing building needs to be expanded, it can be quickly expanded by directly adding connectors 11 and steel sections without redesigning or customizing connectors. This flexibility makes the building highly adaptable in terms of functional changes, space expansion, etc., reduces the design and construction complexity during the expansion process, and significantly reduces the expansion cost.

[0116] 4. Reduce the number of parts and components, and reduce the cost of design, production, assembly and inventory management. Due to the standardization of parts in the system, the number of parts required is significantly reduced, and designers do not need to customize parts for each project, reducing design time and labor costs; the production end also improves production efficiency and reduces production costs through standardized design; in terms of warehousing management, reducing the number of parts makes inventory management more efficient and simple, avoiding inventory backlogs caused by too many parts and improving warehousing efficiency; on the construction end, workers can quickly identify and assemble parts with unified standards, reducing the risk of misuse during construction and improving overall construction efficiency.

[0117] 5. Foolproof design for installation, easy to get started. The design of this system fully considers the foolproof mechanism, and the design of each connector 11 and component follows the principle of universalization to ensure that it is difficult to make mistakes during installation. This foolproof design reduces the problems caused by misuse or incorrect installation of components during installation, and improves the accuracy and safety of installation. Installers do not need to have high skills, and any construction worker can easily master the installation steps after simple training, which greatly reduces the dependence on highly skilled workers, lowers the technical threshold, improves the work efficiency of the construction site and reduces the construction cost.

[0118] 6. High installation efficiency and reduced construction time. Due to the standardized connectors 11 and simplified assembly process of this system, construction workers can assemble quickly and intuitively, significantly improving assembly efficiency. Traditional prefabricated building systems often require workers to identify and install parts of various shapes, while the components of this system are designed to be unified and simple, and the assembly process does not require too much debugging and adjustment, which greatly shortens the construction time. Especially in large-scale construction projects, the improvement of installation efficiency not only shortens the construction period, but also reduces labor costs and project risks caused by delays.

[0119] 7. Resource conservation and waste reduction. The reconfigurability and modular design of this system greatly improve the resource utilization efficiency of the building. All parts can be reused repeatedly, and can be disassembled, reassembled and reassembled to meet different construction needs, reducing the generation of construction waste. Especially during the demolition and reconstruction process, due to the reuse of connectors 11 and steel sections, the waste of materials in the construction process can be significantly reduced, which conforms to the design concept of green environmental protection and further promotes the development of sustainable buildings.

[0120] 8. Adapt to market demand and adjust flexibly. This system can quickly adjust the building structure according to market demand, which not only meets the market demand for rapid response to demand changes, but also can be flexibly expanded under different functional requirements. For construction projects of different scales and functions, the building units 10 can be flexibly increased or decreased according to actual conditions, and the spatial layout can be quickly adjusted. This feature makes the system particularly suitable for commercial buildings, residential communities, temporary buildings and other occasions that require efficient and flexible expansion, and meets the construction industry's ability to respond to rapidly changing needs.

[0121] In summary, the reconfigurable steel structure prefabricated building system 100 of the present application solves multiple technical bottlenecks in traditional prefabricated building systems through standardized design, simplified installation process, no welding connection, high-precision assembly, excellent transportation efficiency, flexible scalability and low-threshold construction requirements, and provides a more efficient, economical and environmentally friendly building solution.

Any changes or substitutions within the technical scope disclosed in the present application should be included in the disclosure scope of the present application.
