Description
Technical Field
[0001] This invention relates to the field of temporary steel structure heavy-duty factory building technology, and more specifically, to a retractable integrated heavy-duty factory building structure that can be transported as a whole and deployed quickly. Background Technology
[0002] In scenarios such as field engineering construction, emergency rescue, and temporary mining, it is often necessary to build temporary heavy-duty workshops for the assembly, welding, and hoisting of large components, as well as for equipment storage and personnel offices.
[0003] Traditional temporary heavy-duty factory buildings often employ modular steel structure construction, which has several significant drawbacks: First, the construction period is long, typically requiring weeks or even months, making it unsuitable for emergency rescue and other urgent scenarios. Second, the cost is high, and the high rate of component scrap after dismantling results in a persistently high life-cycle cost. Third, the need for pouring permanent concrete foundations damages the original ecological environment of the site during construction, necessitating site restoration after dismantling. Fourth, large components must be transported from other locations to the site, incurring high transportation costs and difficulties. Therefore, we propose a retractable integrated heavy-duty factory building structure that can be transported as a whole and deployed rapidly. Summary of the Invention
[0004] The purpose of this invention is to provide a retractable integrated heavy-duty factory structure that can be transported as a whole and deployed quickly, in order to solve the problems of slow construction and difficulty in reuse of traditional temporary heavy-duty factory buildings.
[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a telescopic integrated heavy-duty factory structure that can be transported as a whole and deployed quickly, the factory structure including a foundation base assembly, a column assembly, and a roof steel frame assembly;
[0006] The base assembly is used to support the column assembly after leveling, and the top of the base assembly is connected to the bottom of the column assembly by bolts.
[0007] The column assembly is used to support the roof steel frame assembly and to achieve stepless adjustment of the overall height;
[0008] The roof steel frame assembly is used as a roof support. In use, it has a double-slope symmetrical structure, and in non-use, it is folded up. The roof steel frame assembly is made of soft membrane material and integrated with the roof structure. When folded, the soft membrane and the roof steel frame assembly shrink together. When unfolded, the soft membrane and the roof steel frame assembly unfold together, without the need to disassemble the soft membrane roof separately.
[0009] The walls of the factory structure are made of removable soft membrane material, which can be installed on-site to complete the wall closure. After disassembly, it can be folded and stored for easy reuse.
[0010] Preferably, the foundation base assembly includes a base and at least four corresponding ground piles. The base is a precast concrete embedded steel structure, and the ground piles are located at its bottom. The base is used to fix and connect to the column structure with bolts after leveling.
[0011] Preferably, the column assembly includes a liftable column, the liftable column adopts a multi-stage sleeve structure, and the roof steel frame assembly is hinged to the top of the liftable column.
[0012] Preferably, the roof steel frame assembly consists of an upper chord rigid beam with a double-slope symmetrical structure, a lower chord high-strength steel cable, and vertical folding struts. In the non-use state, the vertical folding struts are folded and retracted, and the upper chord rigid beam is twisted and retracted. In the use state, the vertical folding struts are unfolded, and the upper chord rigid beam is twisted to form a double-slope symmetrical structure with an adjustable slope. The lower chord high-strength steel cable is tensioned to form a prestressed rigid load-bearing beam.
[0013] Preferably, it also includes a support component, which includes inter-column cross bracing and roof bracing, and both the inter-column cross bracing and the roof bracing are flexible steel zippers, used to reinforce the liftable columns and the upper chord rigid beam.
[0014] Preferably, it also includes a rotatable traveling beam, one end of which is hinged to the bracket of the liftable column via a pivot, and can be rotated 90° horizontally around the hinge point to unfold and store. In the non-use state, the rotatable traveling beam rotates 90° to store. In the use state, the other end of the rotatable traveling beam is fixedly connected to the bracket of another adjacent liftable column via a fixing pin.
[0015] Preferably, it also includes a ground rail, which is set on the top of the platform. In the ground rail, a local section corresponding to the liftable column is a load-bearing section for bearing vertical loads, and the remaining sections are guide sections for bearing longitudinal sliding loads and serving as the sliding track of the liftable column, so that the liftable column can slide longitudinally along the sliding track of the ground rail.
[0016] Preferably, it also includes wind-resistant columns, which are disposed at the bottom of the upper chord rigid beam. The wind-resistant columns are multi-segment hinged structures. In use, the wind-resistant columns are twisted into columnar shapes to support the bottom of the upper chord rigid beam. In non-use, the wind-resistant columns are twisted and fitted together for storage.
[0017] Preferably, multiple factory buildings can be combined and expanded in parallel or series to form a factory cluster.
[0018] Compared with the prior art, the beneficial effects of the present invention are:
[0019] 1. By setting up a foundation base assembly, column assembly, and roof steel frame assembly, this invention completely eliminates the cumbersome process of pouring concrete foundations and welding and assembling loose parts on-site for traditional temporary factory buildings, significantly shortening the construction cycle. At the same time, all components are reusable standardized parts, solving the core problems of cumbersome construction procedures, long construction time, and serious waste of materials in traditional temporary heavy factory buildings.
[0020] 2. The disassembly process of this invention results in no structural damage, allowing for complete transfer to the next construction site for reuse. Simultaneously, the height can be infinitely adjusted through the liftable columns, and the span can be dynamically adjusted through the sliding ground rails. This allows for flexible adaptation to the needs of different production processes, equipment heights, and production scales, solving the problems of fixed height, rigid layout, inability to adjust scale, and serious waste from single-use of traditional temporary factory buildings.
[0021] 3. This invention integrates the roof and factory structure into one unit. When folded, the roof shrinks and when unfolded, the roof unfolds, without the need to disassemble the roof separately. The walls are made of detachable soft membrane material, which can be installed on-site to complete the enclosure. After disassembly, it can be folded and stored, further improving the convenience of overall transportation and rapid deployment. Attached Figure Description

[0029] To address the problems of slow construction and difficulty in reusing traditional temporary heavy-duty factory buildings, the following implementation method is proposed.
[0030] Example 1: This example provides a retractable integrated heavy-duty factory structure that can be transported as a whole and deployed quickly. The factory structure includes a foundation base assembly, a column assembly, and a roof steel frame assembly.
[0031] The base assembly is used to support the column assembly after leveling. The top of the base assembly is connected to the bottom of the column assembly by bolts.
[0032] The column assembly is used to support the roof steel frame assembly and to enable stepless adjustment of the overall height;
[0033] The roof steel frame assembly is used as a roof support. When in use, it has a double-slope symmetrical structure, and when not in use, it is folded up.
[0034] In this embodiment, the factory structure is decomposed into three independent and quickly assembled units: the foundation base assembly, the column assembly, and the roof steel frame assembly. The foundation base assembly bears the overall load and completes site leveling. The column assembly serves as the vertical load-bearing core and integrates height adjustment function. The roof steel frame assembly adopts a foldable design to achieve form transformation. The roof steel frame assembly is integrated with the roof structure as one unit. When folded, the roof shrinks, and when unfolded, the roof unfolds, without the need to disassemble the roof separately. The walls of the factory structure are made of detachable flexible membrane material, which is fixed to the columns or roof steel frame on site to form a closed wall. After disassembly, it can be folded and stored for easy overall transportation and reuse. The roof is formed by covering it with foldable weather-resistant and flame-retardant architectural membrane material, and the walls are formed by hanging flexible membrane. The roof and walls can be folded and disassembled during packaging, which fundamentally changes the traditional construction mode of assembling scattered parts on site for temporary factories. Moreover, there is no need to disassemble the scattered components during transportation. They can be loaded onto the vehicle as a whole and transported. After arriving on site, they only need to be simply connected and unfolded for use. This greatly shortens the construction cycle. At the same time, all components are reusable standardized parts with no structural damage after disassembly. This solves the core problems of traditional temporary heavy factory construction, such as cumbersome construction procedures, long time consumption, and serious waste of materials due to single use.
[0035] In this embodiment, the foundation base assembly includes a base 1 and at least four corresponding ground piles 2. The base 1 is a precast concrete embedded steel structure, and the ground piles 2 are set at its bottom. The base 1 is used to fix and connect with the column structure by bolts after leveling.
[0036] In this embodiment, a precast concrete embedded steel structure is used as the foundation 1, which together with at least four ground piles 2 at the bottom forms the foundation bearing system. The foundation 1 is precast in the factory with concrete pouring and steel connectors. On site, only the ground piles 2 need to be driven into the designated position and the foundation 1 needs to be leveled. It can then be directly fixed to the column assembly with bolts. At the same time, the precast foundation 1 and ground piles 2 are both detachable and reusable components. After disassembly, they can be completely transferred to the next construction site for continued use, further reducing costs.
[0037] In this embodiment, the column assembly includes a liftable column 3, which adopts a multi-stage sleeve structure. The roof steel frame assembly is hinged to the top of the liftable column 3, and the liftable column 3 can be equipped with a hydraulic drive device in the prior art to realize stepless adjustment of the height of the liftable column 3.
[0038] This embodiment uses a multi-stage sleeve structure as the main body of the liftable column 3. A hydraulic drive device is built into the liftable column 3. The hydraulic power pushes the sleeves of each stage to slide relative to each other, thereby realizing continuous stepless adjustment of the overall height of the liftable column 3. Unlike traditional factory buildings, there is no need to replace the column members of different lengths according to different height requirements, nor is there any need for on-site cutting, welding and other processing operations. The height adjustment process can be completed by hydraulic automation, with high adjustment accuracy and fast speed. At the same time, the liftable column 3 is an integral structure, which does not need to be disassembled after disassembly and can be transported with the whole factory building for repeated use.
[0039] In this embodiment, the roof steel frame assembly consists of an upper chord rigid beam 4 with a double-slope symmetrical structure, a lower chord high-strength steel cable 5, and a vertical folding strut 6. When not in use, the vertical folding strut 6 is folded and retracted, and the upper chord rigid beam 4 is twisted and retracted. When in use, the vertical folding strut 6 is unfolded, and the upper chord rigid beam 4 is twisted to form a double-slope symmetrical structure with an adjustable slope. The lower chord high-strength steel cable 5 is tensioned to form a prestressed rigid load-bearing beam.
[0040] This embodiment employs a prestressed structure design for the roof steel frame that combines rigidity and flexibility. It consists of a double-slope symmetrical load-bearing system composed of an upper chord rigid beam 4, a lower chord high-strength steel cable 5, and vertical folding struts 6. In the non-use state, the vertical folding struts 6 are folded inward, and the upper chord rigid beam 4 is simultaneously twisted and folded into a compact shape. In the use state, the vertical folding struts 6 are unfolded, the upper chord rigid beam 4 is twisted to the designed slope, and then the lower chord high-strength steel cable 5 is tensioned to apply prestress, forming a rigid beam with high load-bearing capacity. This significantly reduces the transport volume of the roof steel frame, allowing it to be transported as a whole with the factory building. On-site assembly of a large number of scattered roof components is not required; only simple unfolding and tensioning operations are needed to complete the roof construction. At the same time, the prestressed rigid-flexible structure achieves foldable storage of the roof while ensuring heavy load-bearing capacity.
[0041] In this embodiment, a support component is also included, which includes inter-column cross bracing 7 and roof diagonal bracing 8. Both inter-column cross bracing 7 and roof diagonal bracing 8 are flexible steel zippers, used to reinforce the liftable column 3 and the upper chord rigid beam 4.
[0042] In this embodiment, flexible steel cables are used as the main material for the inter-column cross bracing 7 and the roof diagonal bracing 8. The inter-column cross bracing 7 constrains the lateral displacement of the liftable column 3, and the roof diagonal bracing 8 restricts the out-of-plane deformation of the roof steel frame, together forming the overall stability system of the factory building.
[0043] In this embodiment, a rotatable crane beam 9 is also included. One end of the rotatable crane beam 9 is hinged to the bracket of the liftable column 3 via a pivot. It can be rotated horizontally by 90° around the hinge point to unfold and store. In the non-use state, the rotatable crane beam 9 can be rotated by 90° to store. In the use state, the other end of the rotatable crane beam 9 is fixedly connected to the bracket of another adjacent liftable column 3 via a fixing pin.
[0044] In this embodiment, one end of the rotatable crane beam 9 is hinged to the bracket of the liftable column 3 via a pivot, allowing the rotatable crane beam 9 to rotate horizontally by 90° around the hinge point. The other end is fixedly connected to the bracket of the adjacent liftable column 3 via a fixing pin, forming a continuous crane load-bearing beam. This makes the rotatable crane beam 9 an integral part of the overall factory structure, eliminating the need for separate disassembly and transportation, and allowing it to be moved and deployed along with the overall factory structure.
[0045] In this embodiment, a ground rail 10 is also included. The ground rail 10 is set on the top of the pier 1. In the ground rail 10, the local section corresponding to the liftable column 3 is the load-bearing section, which is used to bear the vertical load. The remaining section is the guide section, which is used to bear the longitudinal sliding load and serve as the sliding track of the liftable column 3, so that the liftable column 3 can slide longitudinally along the sliding track of the ground rail 10.
[0046] In this embodiment, a ground rail 10 is installed on the top of the foundation 1, and the ground rail 10 is divided into a load-bearing section and a guide section, which realizes the flexible adjustment of the span and internal space of the factory building. The layout of the factory building can be changed simply by sliding the liftable column 3, which greatly improves the flexibility and adaptability of the factory building deployment.
[0047] In this embodiment, a wind-resistant column 11 is also included. The wind-resistant column 11 is set at the bottom of the upper chord rigid beam 4, and the wind-resistant column 11 is a multi-segment hinged structure. In the use state, the wind-resistant column 11 is twisted into a column shape to support the bottom of the upper chord rigid beam 4. In the non-use state, the wind-resistant column 11 is twisted and fitted for storage.
[0048] This embodiment uses a multi-segment hinged structure as the wind-resistant column 11. The wind-resistant column 11 can be torsional deformed through the hinge points, so that the wind-resistant column 11 does not need to be disassembled and separated. It can be transported and deployed with the whole factory building. On-site deployment can be completed with only simple torsion and fixing operations, which effectively enhances the wind resistance capacity of the end of the factory building.
[0049] In this embodiment, multiple factory buildings can be combined and expanded in parallel or series to form a factory cluster.
[0050] The embodiments disclosed in this invention are preferred embodiments, but are not limited thereto. Those skilled in the art can easily understand the spirit of this invention based on the above embodiments and make different extensions and variations, but as long as they do not depart from the spirit of this invention, they are all within the protection scope of this invention.
