Description

Technical Field

[0001] This invention relates to the field of industrial plant building structure technology, specifically a modular plant supported by shipping containers and its construction method. Background Technology

[0002] The construction of factory buildings in the existing technology has the following problems: 1) Long construction period: Traditional concrete plant requires 3-6 months of construction period, while steel structure plant can be shortened to 1-2 months, but on-site welding and pouring are still required, which is difficult to meet the needs of temporary capacity expansion or relocation. 2) Low modularity: The main body of the factory building (supporting structure, roof, functional areas) is mostly designed as an integrated unit. After disassembly, the reuse rate of components is less than 30%, resulting in high costs for off-site reconstruction. 3) Poor functional adaptability: Fixed unit types are only suitable for a single purpose (such as production / warehousing). If it is necessary to take into account functions such as office and quality inspection, secondary renovation is required, and the space utilization rate is less than 60%. 4) Weak disaster resistance and mobility: Concrete factory buildings are immovable, and temporary simple factory buildings (such as color steel sheds) have low wind and earthquake resistance (mostly below 6 degrees), and cannot adapt to various regional working conditions. Summary of the Invention

[0003] The technical objective of this invention is to address the above-mentioned shortcomings by providing a modular factory building supported by shipping containers and its construction method. The modular factory building structure uses standard shipping containers as the main support and lightweight steel roof trusses as the roofing system, and features rapid assembly, disassembly and reuse, and multi-scenario functional adaptability.

[0004] In a first aspect, the present invention provides a modular factory building supported by shipping containers, comprising container modules, lightweight steel roof truss modules, and functional adaptation modules, wherein... The container module includes containers arranged in rows and columns, the lightweight steel roof truss module includes supports installed on the containers, the upper part of all supports is connected to the roof panel, and the functional adaptation module includes a partition wall that can be detachably installed between adjacent containers.

[0005] The container module includes rectangular containers arranged in four rows and two columns. The length of the containers is along the direction of the columns. The distance between two columns of containers is 6m-8m, and the distance between two adjacent rows of containers is 4m-6m. The containers are fixed to the ground.

[0006] The support structure includes vertical beam connectors welded to both ends and the middle of the outer edge of the top of the container. Vertical beams are bolted to the upper part of the vertical beam connectors, and cross supports are connected between adjacent vertical beams. Wind-resistant column connectors are welded to both ends and the middle of the inner edge of the top of the container. Wind-resistant columns are bolted to the upper part of the wind-resistant column connectors. The height of the wind-resistant columns is greater than the height of the vertical beams. The upper ends of the wind-resistant columns and vertical beams in the same row are connected to the roof beams. Purlins are evenly arranged along the roof beams. The roof panel includes two parts of double-layer color steel plates. Each part of the double-layer color steel plate is installed on the purlins of each row of containers. The gap between the two parts of the double-layer color steel plates is covered and sealed with butyl rubber waterproof tape.

[0007] The vertical beam connector includes an I-beam with a length of 150mm. A connecting plate is welded to one end of the I-beam, and the other end of the I-beam is welded to the top of the container. Four through holes are provided on the connecting plate. The vertical beam includes an H-beam with a base plate welded to its lower end. Four round holes are provided on the base plate. The four through holes and the four round holes are aligned and fastened with bolts and nuts. The wind-resistant column connector has the same structural dimensions as the vertical beam connector.

[0008] Electric skylights are evenly arranged along the column direction on the double-layer color steel plate.

[0009] Shock-absorbing pads are provided between the vertical beam connector and the vertical beam, and between the wind-resistant column connector and the wind-resistant column.

[0010] The partition walls are installed between opposite side walls of containers in the same row, near their outer edges. The edges have slots into which the partition walls engage. Depending on the interior design and function of the factory, the partition walls are installed between the outer walls of the corresponding containers to form partitions within the factory area.

[0011] The container has pre-installed pipe channels and ventilation interfaces inside, and louvers are provided on the side walls of the container.

[0012] Secondly, the present invention provides a construction method for a modular factory building supported by shipping containers, used for constructing the aforementioned modular factory building supported by shipping containers, comprising the following steps: Construction container module: The containers fixed in rows and columns on the ground; Construction of lightweight steel roof truss modules: The brackets are installed on each container, and the upper part of all the brackets is connected to the roof panel. Construction function adaptation module: Based on the factory design, install detachable partition walls between the corresponding containers.

[0013] The modular factory building supported by shipping containers and its construction method of this invention have the following advantages: 1) High efficiency: core components are prefabricated in the factory, and the on-site assembly cycle is only 7-15 days (1 / 10-1 / 5 of that of traditional factory buildings), and no large construction equipment is required; 2) Reusability: the integrity rate of core components such as containers and steel roof trusses after disassembly is ≥90%, and the cost of off-site reconstruction is reduced by more than 60%; 3) Flexibility: by adjusting partitions and replacing functional modules, it is possible to switch between scenarios such as "production + warehousing" and "production + office", and the space utilization rate is increased to 85%; 4) Reliability: the overall seismic resistance level reaches 7 degrees, and the wind load resistance is ≥0.6kN / ㎡, which is suitable for industrial environments in many regions such as the Yangtze River Delta and the Pearl River Delta; 5) Economy: the construction cost per square meter is about 800-1200 yuan (70% of that of traditional steel structure factory buildings), and the annual operation and maintenance cost is reduced by 20% (due to the ease of maintenance of modular facilities).

Example

[0022] like Figures 1-7As shown, the modular factory building supported by containers provided in this embodiment includes three main modules: container module, lightweight steel roof truss module, and functional adaptation module.

[0023] The container module 1 includes containers 11 arranged in rows and columns. In this embodiment, the container module 1 may include rectangular containers 11 arranged in four rows and two columns, arranged in a "matrix" manner. The length direction of the containers 11 is along the direction of the columns. The distance between two columns of containers 11 is 6m-8m, and the distance between two adjacent rows of containers is 4m-6m. The containers are fixed to the ground to ensure the stability and safety of the overall structure.

[0024] The shipping containers serve as the main load-bearing structure and also enclose the factory space. Based on the factory's functional requirements, the containers are rationally arranged, with adjustments made to the distances between rows and columns according to load demands. This ensures efficient space utilization and convenient passageway planning, providing ample space for personnel movement and equipment operation while also prioritizing safety.

[0025] In this embodiment, a 20-foot or 40-foot standard container made of Q235 steel can be used.

[0026] The container can be pre-installed with pipeline channels 6 and ventilation interfaces 7, and can be equipped with operable louvers (ventilation rate ≥30%) on the side walls. Depending on the function of each container, it can be converted into an office area, control room, or auxiliary room, etc.

[0027] The lightweight steel roof truss module 2 includes brackets 21 installed on each container, with the upper part of all brackets 21 connected to the roof panel 22. The lightweight steel roof truss module 2 is a roofing system.

[0028] The support frame 21 includes vertical beam connectors 211 welded to both ends and the middle of the outer edge of the top of the container. Vertical beams 212 are bolted to the upper part of the vertical beam connectors 211, and cross supports 213 are connected between adjacent vertical beams 212. Wind-resistant column connectors 214 are welded to both ends and the middle of the inner edge of the top of the container. Wind-resistant columns 215 are bolted to the upper part of the wind-resistant column connectors 214. The height of the wind-resistant columns 215 is greater than the height of the vertical beams 212. The upper ends of the wind-resistant columns 215 and the vertical beams 212 in the same row are connected to the roof beams 216. Purlins 217 are evenly arranged along the roof beams 216. The roof panel 22 includes two double-layer color steel plates 221. Each double-layer color steel plate 221 is installed on the purlins 217 of each row of containers. The gap between the two double-layer color steel plates 221 is covered and sealed with butyl rubber waterproof tape 222. Each section of double-layer color steel plate 221 is composed of several double-layer color steel plates 221 overlapped together.

[0029] The vertical beam connector 211 includes an I-beam 2111 with a length of 150mm. A connecting plate 2112 is welded to one end of the I-beam 2111, and the other end of the I-beam 2111 is welded to the top of the container. Four through holes are provided on the connecting plate 2112. The vertical beam includes an H-beam 2121, and a base plate 2122 is welded to the lower end of the H-beam 2121. Four round holes are provided on the base plate 2122. The four through holes and four round holes are aligned and fastened with bolts and nuts. The wind-resistant column connector 214 has the same structural dimensions as the vertical beam connector 211. The wind-resistant column and the vertical beam can use the same specification of H-beam 2121.

[0030] Lightweight H-beams 2121 (HW200×200) are used as vertical beams, with a spacing of approximately 6m. Cross supports 213 can also be made of lightweight H-beams 2121, forming a stable structure. Wind-resistant columns can also be made of H-beams 2121. The vertical beams are bolted to the vertical beam connectors 211 welded to the top of the container, and the wind-resistant columns are bolted to the wind-resistant column connectors 214 welded to the top of the container, facilitating easy installation and disassembly. Purlins 217 can be made of C-beams (C160×60) with a spacing of 1.2m.

[0031] Vibration damping pads 5 are installed between the vertical beam connector 211 and the vertical beam, and between the wind-resistant column connector 214 and the wind-resistant column. The vibration damping pads 5 can be made of anti-vibration rubber pads with a thickness of 50mm and a damping coefficient of 0.3 to reduce vibration transmission.

[0032] The outer layer of the double-layer color steel plate 221 is a 0.6mm color-coated steel plate, and the inner layer is a 0.5mm color steel plate. A 100mm layer of insulation cotton and aluminum foil is sandwiched between the outer and inner layers. The double-layer color steel plates 221 are connected by an interlocking mechanism. Because the wind-resistant columns are higher than the vertical beams, a ridge is formed in the middle of the two sections of double-layer color steel plates 221. There will be gaps in the ridges. To seal these gaps, the gap between the two double-layer color steel plates 221 is covered and sealed with butyl rubber waterproof tape 222, with a width of up to 50mm, for waterproofing. Weather-resistant sealant (temperature resistant from -40℃ to 80℃) is applied to the overlap of the double-layer color steel plates 221.

[0033] Electric skylights 4 are evenly arranged along the direction of the columns on the double-layer color steel plate 221. The electric skylights 4 can be installed close to the ridge, can be opened electrically, facilitate ventilation, and have an exhaust volume ≥1200m³ / h.

[0034] Hanging points can be reserved at appropriate locations on the roof beam 216, with one point every 10m along the column direction, each bearing 5t, to suspend overhead cranes or lifting equipment; photovoltaic panels (bearing capacity ≥20kg / ㎡) can be laid on the roof panel 22 to accommodate distributed energy systems.

[0035] The functional adaptation module 3 includes a partition wall 31 that can be detachably installed between adjacent containers.

[0036] To support flexible switching between various scenarios such as production, warehousing, and office, the partitions between the containers are detachable. Inside the factory, partition walls 31 can be installed between the corresponding container exterior walls using slots 32 at locations where partitions are needed, forming partitions within the factory area. On the factory perimeter, partition walls 31 are installed between adjacent containers, with the partition walls 31 and the container exterior walls together forming the factory's exterior walls.

[0037] In this embodiment, the partition wall 31 is installed between the opposite side walls and near the outer edges of each row of containers. A locking groove 32 is bolted to the edge, and the partition wall 31 is secured in the groove 32. The left and right edges of the partition wall 31 are firmly engaged in the corresponding grooves 32, facilitating installation and disassembly. The partition wall 31 and the containers together form a rectangular factory building. Factory doors can be installed between the opposite side walls of the first two containers and between the opposite side walls of the last two containers.

[0038] This embodiment has advantages such as short construction period (generally 7-15 days), high component reuse rate (≥90%), high space utilization rate (≥85%), and good seismic and wind resistance performance, making it suitable for industrial plant needs in multiple regions and with multiple functions.

[0039] The partition wall 31 is a detachable light steel keel partition with a thickness of 100mm and an internal rock wool insulation layer. It can be quickly installed through the pre-reserved slot 32 on the side wall of the container, realizing flexible zoning of the production area and storage area inside the factory.

[0040] This embodiment uses standard shipping containers as the main load-bearing structure of the factory building, which are quickly connected to a lightweight steel roof truss via bolts, achieving modularization, standardization, and rapid assembly / disassembly of the main structure. Detachable lightweight steel keel partitions and pre-installed pipeline channels allow for flexible zoning and rapid adaptation of the factory's internal functions, supporting switching between production, warehousing, and office scenarios. Anti-seismic rubber pads are installed at the connection points between the containers and the roof truss, wind-resistant columns are installed at both ends of the roof truss, and butyl rubber waterproof tape 222 is used at the joints, significantly improving the overall seismic resistance (≥7 degrees), wind resistance (≥0.6 kN / ㎡), and waterproofing performance. While ensuring structural safety, this embodiment achieves a significantly shortened construction period, high component reuse rate, efficient space utilization, and reduced operation and maintenance costs, demonstrating good economic efficiency and environmental adaptability.
