[0035] It should be further understood that the term "and / or" as used in the present application specification and the appended claims means any combination of one or more of the associated listed items and all possible combinations, and includes these combinations.

[0036] As shown in Figures 1-5 The steel structure modular building suite provided by the embodiment of the present application comprises a box module 100, the box module 100 comprises a frame body 30 and a box top prefabricated integral floor connected with the frame body 30, the box top prefabricated integral floor comprises prefabricated stressed floors 10 and corrugated steel plates 20 adjacent in the horizontal direction; the prefabricated stressed floor 10 comprises a flat plate section 11 and folded plate sections 12 extending downward from opposite sides of the flat plate section 11, the folded plate sections 12 are connected with the frame body 30 and form a first preset vertical space together with the flat plate section 11; the corrugated steel plates 20 are connected with the folded plate sections 12 and the frame body 30 respectively at opposite sides, and the corrugated steel plates 20 form a second preset vertical space together with the folded plate sections 12 above the box module 100.

[0037] In the embodiment, the building suite comprises a box module 100. The box module 100 mainly comprises a frame body 30 and a box-top prefabricated monolithic floor connected with the frame body 30, wherein the box-top prefabricated monolithic floor comprises prefabricated stressed floors 10 and corrugated steel plates 20 arranged adjacent to each other in the horizontal direction, forming a composite box-top prefabricated monolithic floor. Here, "adjacent to each other" specifically means that the prefabricated stressed floors 10 and the corrugated steel plates 20 are arranged in close proximity on the same horizontal plane, wherein the prefabricated stressed floors 10 are arranged above the main use space (such as a bedroom, etc.) of the suite, and the corrugated steel plates 20 are arranged above the secondary space (such as a bathroom, etc.). This arrangement fully considers the differentiated needs of different functional spaces for structural performance.

[0038] The prefabricated stressed floor 10 comprises a flat plate section 11 arranged horizontally and folded plate sections 12 arranged on opposite sides of the flat plate section 11. The folded plate sections 12 are arranged downwardly bent relative to the flat plate section 11 and connected with the frame body 30. This design makes the folded plate sections 12 and the flat plate section 11 form a first preset vertical space above the frame body 30, which can be used as a net height space within the box module 100, to solve the technical problem of insufficient building net height caused by excessive structural height (about 600 mm) at the module connection in traditional steel structure modular buildings. Here, the opposite sides refer to the two opposite edge positions of the flat plate section 11.

[0039] The corrugated steel plates 20 are connected with the folded plate sections 12 and the frame body 30 on opposite sides, respectively, so that the corrugated steel plates 20 and the folded plate sections 12 form a second preset vertical space above the box module 100. This design not only meets the waterproofing and load-bearing requirements during construction, but also provides installation space for the steel bar truss floor slab 40 of the upper box module 100. Compared with the traditional design of dense ribbed beams and corrugated plates, the corrugated steel plates 20 in the embodiment can not only meet the functional requirements during construction, but also serve as permanent structural components, avoiding material waste. Here, the opposite sides refer to the two opposite edges of the corrugated steel plate in the horizontal direction. That is, one side of the corrugated steel plate 20 is connected with the folded plate section 12, and the other side is connected with the frame body 30.

[0040] The design of the steel structure modular building suite fully considers the needs of assembly construction. The prefabricated stressed floor 10 can be prefabricated in the factory and directly installed on site after transportation. The arrangement of the corrugated steel plate 20 simplifies the construction process and improves the construction efficiency. Through the reasonable matching of the prefabricated stressed floor 10 and the corrugated steel plate 20, the overall performance of the structure is guaranteed, and the internal net height effect of the building is significantly improved.

[0041] Through the above embodiment, the structural height of the module connection is reduced, so that a larger net height space can be obtained in a dormitory room with a layer height of 3.6 m, thereby meeting the requirement of 3.4 m net height of the dormitory. At the same time, the composite box top prefabricated integral floor cancels the dense rib beam and corrugated plate structure (about 450-550 kg) in the traditional design only for meeting the demand in the construction stage, and instead adopts a permanent structure that can meet the temporary demand during construction and the bearing demand in the whole life cycle of the building. In this way, the material consumption can be reduced, and the construction cost can be reduced.

[0042] In an embodiment, the frame body 30 includes relatively distributed force columns 31, the top ends of the force columns 31 are respectively provided with first top beams 32 and second top beams 33 between the folded plate section 12 and the corrugated steel plate 20, and the bottom ends of the force columns 31 are respectively provided with bottom beams 34; the folded plate section 12 is arranged on the top of the first top beam 32 and forms a first preset horizontal space with the first top beam 32.

[0043] In the embodiment, the frame body 30 includes relatively distributed force columns 31, which not only bear the vertical load of the entire box module 100, but also provide the necessary lateral stiffness. In order to realize the reliable connection of the prefabricated force floor 10 and the corrugated steel plate 20 with the frame body 30, the top ends of the force columns 31 are respectively provided with first top beams 32 and second top beams 33, wherein the first top beams 32 are fixedly connected with the folded plate section 12, and the second top beams 33 are fixedly connected with the corrugated steel plate 20. The bottom ends of the force columns 31 are provided with bottom beams 34 for supporting the entire box module 100.

[0044] Specifically, the folded plate section 12 is arranged on the top of the first top beam 32 and forms a first preset horizontal space with the first top beam 32. This arrangement not only ensures the reliable connection of the folded plate section 12 with the frame body 30, but also provides sufficient installation and adjustment space for subsequent construction by reserving the first preset horizontal space. The provision of the first preset horizontal space makes it possible to better coordinate the positional relationship between the components during the installation of the box module 100, thereby improving the construction accuracy.

[0045] The structural design of the frame body 30 fully considers the characteristics of modular buildings, and forms a complete force system through the reasonable arrangement of the force columns 31, the top beams and the bottom beams 34. At the same time, the provision of the preset horizontal space also provides a convenient condition for on-site installation.

[0046] In an embodiment, the box module 100 further includes a steel bar truss floor slab 40, which is arranged in the frame body 30 and connected to the top of the bottom beam 34.

[0047] In the embodiment, the box module 100 further comprises a steel bar truss floor slab 40. The steel bar truss floor slab 40 is arranged inside the frame body 30 and connected to the top of the bottom beam 34, and is mainly used to form a floor structure to bear the floor self weight and use load.

[0048] Specifically, the steel bar truss floor slab 40 is produced in a factory prefabricated manner, and the specification and size thereof are determined according to actual design requirements. The steel bar truss floor slab 40 is fixed to the top of the bottom beam 34 by a reliable connection manner to form a stable floor load-bearing component.

[0049] In the embodiment, the steel bar truss floor slab 40 is the same as the prefabricated stressed floor slab 10, and is also a factory prefabricated part.

[0050] In an embodiment, the box module 100 comprises an upper box module 100 and a lower box module 100 arranged in a vertical stack; the steel bar truss floor slab 40 of the upper box module 100 is arranged in the second preset vertical space of the lower box module 100; and a second preset horizontal space is formed between the steel bar truss floor slab 40 of the upper box module 100 and the second top beam 33 of the lower box module 100.

[0051] In the embodiment, the plurality of box modules 100 respectively comprise an upper box module 100 and a lower box module 100. By this vertical stacking manner, a multi-story building structure can be constructed.

[0052] Specifically, the steel bar truss floor slab 40 of the upper box module 100 is arranged in the second preset vertical space of the lower box module 100. That is, the second preset vertical space formed by the corrugated steel plate 20 and the folded plate segment 12 in the lower box module 100 not only meets the waterproofing and load-bearing requirements during construction, but also provides installation space for the steel bar truss floor slab 40 of the upper box module 100. This design fully utilizes the space between the modules and effectively reduces the total height of the structure.

[0053] A second preset horizontal space is formed between the steel bar truss floor slab 40 of the upper box module 100 and the second top beam 33 of the lower box module 100. The preset horizontal space is mainly used to accommodate the bottom beam 34 of the upper box module 100, thereby realizing reliable connection between the upper and lower box modules 100. Through this design, the integrity of the structure is ensured, and necessary construction installation space is provided.

[0054] This module stacking manner realizes effective connection between the upper and lower box modules 100 by reasonably arranging the preset space to accommodate the connecting component, and also solves the problem of excessive structural height at the connection of the traditional steel structure modular building.

[0055] In an embodiment, the bottom beam 34 of the upper box module 100 is embedded in the first and second preset horizontal spaces of the lower box module 100, respectively.

[0056] In the present embodiment, the bottom beam 34 is arranged in the preset horizontal spaces of the lower box module 100 at the connection between the upper box module 100 and the lower box module 100, so as to optimize the structural height. The first preset horizontal space is formed between the folded plate segment 12 and the first top beam 32, and the second preset horizontal space is formed between the steel bar truss floor slab 40 and the second top beam 33. This design enables the bottom beam 34 to be effectively "hidden" in the reserved space, avoiding the problem of increased structural height caused by the bottom beam 34 in the traditional design.

[0057] This arrangement makes full use of the existing preset horizontal space without the need for additional structural height. By embedding the bottom beam 34 in the preset horizontal space, a compact connection between the upper and lower box modules 100 is achieved.

[0058] In an embodiment, the thickness of the folded plate segment 12 is not less than 100 mm, and the folded plate segment 12 is integrally formed with the flat plate segment 11 by reinforced concrete pouring.

[0059] In the present embodiment, the thickness of the folded plate segment 12 is set to be not less than 100 mm. On the one hand, this can meet the minimum thickness requirement of reinforced concrete components, ensuring the integrity and durability of the structural components. On the other hand, appropriately increasing the thickness of the folded plate segment 12 can improve its bending moment resistance, enabling the folded plate segment 12 to bear larger architectural dead loads, live loads, and construction loads, etc.

[0060] In terms of construction technology, the folded plate segment 12 is integrally formed with the flat plate segment 11 by reinforced concrete pouring. This integral pouring construction method can ensure reliable integral connection between the folded plate segment 12 and the flat plate segment 11, avoiding the connection reliability problems that may exist in the traditional prefabricated component splicing. During pouring, the steel bars need to be arranged reasonably, especially at the connection between the folded plate segment 12 and the flat plate segment 11, where the reinforcement 13 should be appropriately strengthened to offset the unbalanced bending moment. Through this integral pouring process, the integrity and load-bearing performance of the structure can be effectively guaranteed.

[0061] In a specific embodiment, reinforcing bars 13 are arranged in both the flat slab section 11 and the folded slab section 12, and the number of reinforcing bars 13 in the folded slab section 12 is greater than that in the flat slab section 11. This arrangement of reinforcing bars 13 is mainly based on the following considerations: on the one hand, the flat slab section 11 mainly bears vertical loads, and the reinforcing bars 13 arranged therein meet the normal use requirements; on the other hand, since there is an unbalanced bending moment between the folded slab section 12 and the flat slab section 11, the number of reinforcing bars 13 in the folded slab section 12 needs to be appropriately increased to offset this unbalanced bending moment, so as to ensure the overall stress performance of the prefabricated stressed floor 10.

[0062] In an embodiment, the width of the bottom beam 34 is less than the width of the first top beam 32 and the second top beam 33 respectively.

[0063] In the present embodiment, the (first and second) top beams need to provide sufficient support width for the bottom beam 34 of the upper box module 100, while also meeting the requirements of construction and installation. By appropriately widening the top beams, more positioning and adjusting space can be provided for the bottom beam 34 of the upper box module 100, facilitating on-site installation and position adjustment.

[0064] Secondly, the bottom beam 34 mainly bears the vertical loads transmitted from the upper structure and transmits them to the lower structure. Since the bottom beam 34 is arranged in a predetermined horizontal space, its width should be adapted to the predetermined space. By reducing the width of the bottom beam 34, it can be better embedded in the predetermined horizontal space, thereby realizing compact connection of the structure.

[0065] This beam width differentiation design not only meets the structural stress requirements, but also improves the operability of construction, which is a design that takes into account both structural performance and construction convenience.

[0066] In an embodiment, a support side plate 50 is arranged between the connection between the prefabricated stressed floor 10 and the corrugated steel plate 20 and the steel bar truss floor support plate 40.

[0067] In the present embodiment, in order to strengthen the structural stability of the connection between the prefabricated stressed floor 10 and the corrugated steel plate 20, and also to separate the space within the box module 100, a support side plate 50 is arranged between the connection between the prefabricated stressed floor 10 and the corrugated steel plate 20 and the steel bar truss floor support plate 40.

[0068] The support side plate 50 provides additional support for the connection between the prefabricated stressed floor 10 and the corrugated steel plate 20, enhancing the stability of the connection; secondly, the support side plate 50 can also divide the space within the box module 100, so that the space below the prefabricated stressed floor 10 serves as a dormitory, and the space below the corrugated steel plate 20 serves as a bathroom.

[0069] In an embodiment, a leakage-proof sealing structure 60 is arranged at the connection between the upper box module 100 and the lower box module 100.

[0070] In this embodiment, a leak-proof sealing structure 60 is provided between the upper box module 100 and the lower box module 100. Specifically, the leak-proof sealing structure 60 is provided between the top beam and the corresponding first top beam 32 and second top beam 33, and between the steel truss floor deck 40 of the upper box module 100 and the corrugated steel plate 20 below it.

[0071] The installation of this leak-proof sealing structure 60 not only solves the problem of leakage at the joints of traditional modular buildings, but also improves the overall service life of the building and provides residents with a better living environment.

[0072] like Figure 6 As shown, corresponding to the above-mentioned modular steel structure building suite, this utility model embodiment also provides a construction method for a modular steel structure building suite, which includes the following steps:

[0073] S100, the load-bearing column 31, the first top beam 32, the second top beam 33, and the bottom beam 34 are assembled to form the main frame 30. Specifically, the first top beam 32, the second top beam 33, and the bottom beam 34 are first connected to the load-bearing column 31 to form a stable frame structure. This step provides basic support for the subsequent installation of the precast monolithic floor slab on the box roof.

[0074] S200. Lift the precast integral floor slab on the top of the box girder to the predetermined installation position of the main frame 30. Specifically, lift the precast load-bearing floor slab 10 and the corrugated steel plate 20 as a whole to the predetermined installation position. Since the precast load-bearing floor slab 10 is produced in a factory using a prefabrication method, product quality can be guaranteed. At the same time, the installation by lifting as a whole can improve construction efficiency and reduce on-site work.

[0075] S300. The precast integral floor slab of the box roof is fixedly connected to the frame body 30 through the first top beam 32 and the second top beam 33. Specifically, the folded plate section 12 of the precast load-bearing floor slab 10 is fixedly connected to the frame body 30 through the first top beam 32, and the corrugated steel plate 20 is fixedly connected to the frame body 30 through the second top beam 33.

[0076] S400, the upper box body module 100 is lifted above the lower box body module 100, and grouting is carried out at the connection of the upper box body module 100 and the lower box body module 100. Specifically, the upper box body module 100 is hoisted above the lower box body module 100, the steel truss floor slab 40 of the upper box body module 100 enters the second preset vertical space of the lower box body module 100, and the bottom beam 34 of the upper box body module 100 is embedded in the first preset horizontal space and the second preset horizontal space of the lower box body module 100; grouting is carried out at the connection of the upper box body module 100 and the lower box body module 100 to form an integral connection.

[0077] Through the above construction steps, the rapid installation and reliable connection of the steel structure modular building suite can be realized. This construction method not only improves the construction efficiency, but also ensures the construction quality. At the same time, by adopting the lifting installation mode of the prefabricated integral floor slab on the box top, combined with the composite structure design of the prefabricated stressed floor slab 10 and the corrugated steel plate 20, the structural height of the module connection can be effectively reduced; the dense rib beam and the corrugated plate structure (about 450-550 kg) used only in the construction stage in the traditional design are cancelled, and the material consumption and construction cost are reduced.

[0078] In the present embodiment, during the prefabricated component (prefabricated integral floor slab on the box top) manufacturing stage, a grouting groove needs to be reserved at the bottom of the folded plate section 12 of the prefabricated stressed floor slab 10. The position of the grouting groove should correspond to the position of the bolt on the top of the steel beam (the first top beam 32 and the second top beam 33).

[0079] In actual construction, first, the measurement is used to ensure that the prefabricated floor slab is accurately positioned, and necessary temporary supports are set to ensure stability during the construction process. After the component is positioned, the alignment of the reserved gap, the grouting groove and the bolt is reviewed. The grouting construction adopts the pressure grouting method to ensure that the grouting material can be fully filled. During the construction, the grouting should be started from one end of the grouting groove and gradually pushed forward, and the flow of the grouting material is observed through the overflow hole to ensure that the grouting material completely fills the grouting groove.

[0080] Through the above grouting connection method, the reliable connection of the prefabricated integral floor slab on the box top and the steel beam can be realized, and an integral stressed system is formed. After the grouting connection is completed, the entire box structure forms an integral whole, which can bear stress cooperatively, thereby improving the overall performance and service life of the building.

[0081] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any skilled person in the art can easily think of various equivalent modifications or replacements within the technical range disclosed by the present application, and these modifications or replacements should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
