[0002] At present, steel structure modularization building obtains more extensive application in school, hospital, hotel and other public buildings. However, in residential, dormitory and other residential buildings, although certain adaptability is possessed, application is relatively less.

[0003] The existing steel structure modularization building usually adopts the construction form of "bottom main frame bearing + top dense rib beam + corrugated plate covering". The bottom bears the floor self-weight load and use load through the steel bar truss floor slab, and the top adopts dense rib beam and corrugated plate covering, mainly satisfying the waterproof and construction load demand during construction. However, this design has the following problems:

[0004] Considering structural stress, deformation and installation process and other factors, after the upper and lower box bodies of the module are assembled, the structural height at the floor is about 600mm (including the bottom main beam and the top dense rib beam). Taking the dormitory with the layer height of 3.6m as an example, after deducting the structural height, the actual net height is only 3.07m, which is far lower than the standard requirement of 3.4m of residential building. This problem of insufficient net height limits the application of the steel structure modularization in residential buildings.

[0005] Therefore, at present, how to improve the net height of the living space is an urgent problem to be solved. CONTENT OF UTILITY MODEL

[0032] Please refer to the drawings simultaneouslyFigures 1-5 The utility model embodiment provides a kind of steel structure modular building room, including box module 100, box module 100 includes prefabricated stressed floor 10, prefabricated stressed floor 10 includes the horizontal arrangement flat section 11 and is set to the bellow section 12 of flat section 11 opposite two sides, bellow section 12 is bent down relative to flat section 11 and is set, so that bellow section 12 and flat section 11 between in box module 100 inside form preset vertical space;Box module 100 further include frame, frame includes stressed column 20, top beam 30 and bottom beam 40, the top end of each stressed column 20 is connected with top beam 30, and bottom end is connected with bottom beam 40;Wherein, prefabricated stressed floor 10 is fixedly connected in frame by top beam 30, bellow section 12 is set to the top of top beam 30, and form preset horizontal space between top beam 30.

[0033] In the embodiment, box module 100 includes prefabricated stressed floor 10 and frame, and the frame further includes stressed column 20, top beam 30 and bottom beam 40.Through the optimization design of box module 100, the problem of insufficient net height of residential building in prior art can be effectively solved.

[0034] Specifically, prefabricated stressed floor 10 includes horizontal arrangement flat section 11 and is set to the bellow section 12 of flat section 11 opposite two sides.Bellow section 12 is bent down relative to flat section 11 and is set.Through this setting mode, bellow section 12 and the bottom of flat section 11 form preset vertical space H1 for guaranteeing building use space, and the preset vertical space H1 can be used as the net height space in box module 100.

[0035] Stressed column 20 is arranged on the bottom side of prefabricated stressed floor 10. Specifically, two stressed columns 20 are arranged on the left and right spaces of the bottom of prefabricated stressed floor 10. Top beam 30 is arranged between prefabricated stressed floor 10 and each stressed column 20, and bottom beam 40 is arranged at the bottom end of each stressed column 20. Top beam 30 serves as the supporting structure of prefabricated stressed floor 10, and its width should meet the supporting structure requirements. Top beam 30 and bottom beam 40 are made of profile steel and are fixedly connected to stressed column 20 by bolt connection.

[0036] Bellow section 12 is arranged on the top of top beam 30 and forms preset horizontal space with top beam 30. This arrangement can reserve space for the connection between the upper and lower box modules 100, and is also conducive to installation and positioning during construction.

[0037] In a specific embodiment, the prefabricated force floor 10 is in the form of a C-shaped plate structure, with the C-shaped opening facing downward, i.e., toward the inside of the box module 100. The folded plate segments 12 are the two side wing portions of the C-shaped plate structure, which are arranged on opposite sides of the flat plate segment 11, i.e., the two folded plate segments 12 are arranged on the left side and the right side of the flat plate segment 11, respectively.

[0038] In this embodiment, the folded plate segments 12 are arranged on the flat plate segment 11 to form a predetermined vertical space H1, which not only ensures the internal use space of the room but also ensures the overall rigidity of the prefabricated force floor 10, effectively solving the problem of insufficient net height in the prior art of residential steel structure modular buildings. In addition, by arranging a predetermined horizontal space at the top of the box module 100 for accommodating the bottom beam 40 of the upper box module 100, reliable connection between the upper and lower box modules 100 is achieved, and the stability of the overall structure is improved.

[0039] In an embodiment, the thickness of the folded plate segment 12 is not less than 100 mm, and the folded plate segment 12 is connected to the flat plate segment 11 by integral pouring of reinforced concrete.

[0040] In this embodiment, the thickness of the folded plate segment 12 is set to be not less than 100 mm, which on the one hand can meet the minimum thickness requirement of reinforced concrete components to ensure the integrity and durability of the structural components, and on the other hand, appropriately increasing the thickness of the folded plate segment 12 can improve its bending moment resistance, so that the folded plate segment 12 can bear larger architectural dead loads, live loads, and construction loads, etc.

[0041] The folded plate segment 12 is connected to the flat plate segment 11 by integral pouring of reinforced concrete. This integrated connection method can effectively ensure the structural integrity and avoid the connection reliability problems that may be caused by traditional post-connection methods. By integral pouring, not only the overall force performance of the prefabricated force floor 10 is improved, but also the construction process is simplified and the construction efficiency is improved.

[0042] In an embodiment, reinforcement 13 is arranged in the flat plate segment 11 and the folded plate segment 12, and the number of reinforcement 13 in the folded plate segment 12 is greater than that in the flat plate segment 11.

[0043] In this embodiment, this arrangement of reinforcement 13 is mainly based on the following considerations: on the one hand, the flat plate segment 11 mainly bears vertical loads, and the arrangement of reinforcement 13 meets the normal use requirements; on the other hand, since there is an unbalanced bending moment between the folded plate segment 12 and the flat plate segment 11, the number of reinforcement 13 in the folded plate segment 12 needs to be appropriately increased to offset this unbalanced bending moment, so as to ensure the overall force performance of the prefabricated force floor 10.

[0044] In an embodiment, a plurality of box modules 100 are provided, including an upper box module 100 and a lower box module 100. The bottom beam 40 of the upper box module 100 is arranged in a preset horizontal space of the lower box module 100. The horizontal gap between the bottom beam 40 of the upper box module 100 and the folded plate section 12 of the lower box module 100 is not less than 20 mm.

[0045] In the present embodiment, a plurality of box modules 100 are provided, including an upper box module 100 and a lower box module 100. When a multi-story building needs to be built, the assembly of the box modules 100 can be achieved by stacking them up and down.

[0046] As shown in Figure 2 and Figure 3 , the bottom beam 40 of the upper box module 100 is arranged in a preset horizontal space of the lower box module 100. Specifically, when two box modules 100 are installed by stacking them up and down, the bottom beam 40 of the upper box module 100 can be embedded in the preset horizontal space W1 of the lower box module 100, and the stable connection between the upper and lower box modules 100 can be achieved by cooperating with the post-grouting process. It is worth noting that, as shown in Figure 1 , the upper box module 100 refers to the box module 100 located at the upper layer, and the lower box module 100 refers to the box module 100 located at the lower layer.

[0047] In the present embodiment, the horizontal gap between the folded plate section 12 and the adjacent bottom beam 40 is not less than 20 mm. This arrangement is mainly based on the following consideration: since there are inevitable construction errors in the construction process of steel modular buildings, reserving appropriate construction error space can effectively improve the construction performance and improve the installation efficiency.

[0048] In a specific embodiment, the width of the horizontal gap W2 is set to 20-23 mm. This specific numerical range is determined based on actual construction experience, which can meet the construction error requirements and will not excessively affect the overall performance of the structure.

[0049] In an embodiment, the plurality of box modules 100 further include box modules 100 distributed in the horizontal direction, and a leakage-proof sealing structure 50 is arranged between two adjacent box modules 100 in the horizontally distributed box modules 100. The leakage-proof sealing structure 50 is arranged between the top beams 30 of the two adjacent box modules 100.

[0050] In the present embodiment, as shown in Figure 5As shown, the box modules 100 in the steel structure modular building room are not only stacked in the vertical direction, but also include box modules 100 distributed side by side in the horizontal direction. In order to ensure the waterproof performance of the building, a leakage-proof sealing structure 50 is arranged between two adjacent box modules 100 in the horizontal direction.

[0051] Specifically, the leakage-proof sealing structure 50 is arranged between the top beams 30 of two adjacent box modules 100. This arrangement mainly takes into account that the top beam 30, as a supporting structure of the prefabricated load-bearing floor 10, is most prone to leakage at the connection. By arranging the leakage-proof sealing structure 50 between the top beams 30, water can be effectively prevented from seeping from the module connection, thereby ensuring the overall waterproof performance of the building.

[0052] The arrangement of such a leakage-proof sealing structure 50 not only solves the problem of leakage at the horizontal joint of the traditional modular building, but also improves the overall service life of the building, providing a better living environment for the occupants.

[0053] In an embodiment, the width of the bottom beam 40 is less than the width of the top beam 30.

[0054] In this embodiment, first, the top beam 30 needs to serve as a supporting structure of the prefabricated load-bearing floor 10, and its width should meet the supporting requirements; second, the bottom beam 40 mainly serves to connect and transmit forces, and its width can be appropriately reduced, which not only reduces the structural self-weight, but also reduces the amount of steel used, improving the economy.

[0055] As shown, Figure 6 For the above steel structure modular building room, the utility model embodiment further provides a construction method, which comprises the following steps:

[0056] S100, the load-bearing column 20, the bottom beam 40 and the top beam 30 are assembled to form a frame.

[0057] In this embodiment, the top beam 30 and the bottom beam 40 are first connected to the load-bearing column 20 respectively to finally form a stable frame structure. This step provides a foundation support for the subsequent installation of the prefabricated load-bearing floor 10.

[0058] S200, the prefabricated load-bearing floor 10 is lifted as a whole to a predetermined installation position of the frame.

[0059] In this embodiment, the prefabricated load-bearing floor 10 is lifted as a whole to a predetermined installation position for fixation. The predetermined installation position refers to the upper side of the top beam. The whole lifting refers to lifting the prefabricated load-bearing floor 10 (prefabricated part) to the upper side of the top beam, so as to facilitate the assembly of the building room.

[0060] S300, the prefabricated force floor 10 is fixedly connected to the frame through the roof beam 30.

[0061] In this embodiment, firstly, the relative position of the prefabricated force floor 10 and the force column 20 should be ensured to be accurate, and temporary fixing measures can be used for positioning. Then, the prefabricated force floor 10 and the force column 20 are reliably connected through bolt connection. The connection process is realized through the roof beam 30, and since the roof beam 30 serves as a supporting structure, the reliability of the connection can be effectively ensured.

[0062] S400, the upper box module 100 is lifted above the lower box module 100, and post-grouting is performed at the connection between the upper box module 100 and the lower box module 100.

[0063] In this embodiment, the purpose of this step is to enhance the integrity between the upper and lower box modules 100. Specifically, the grouting area should be cleaned first to ensure that there are no impurities. Then, special grouting material is used for grouting, and the grouting process should be continuous to ensure that the grouting is dense and full.

[0064] In an embodiment, after the upper box module 100 is lifted above the lower box module 100 and post-grouting is performed at the connection between the upper box module 100 and the lower box module 100, it further includes: performing anti-leakage treatment on the splicing part of the box modules 100 adjacent in the horizontal direction.

[0065] In this embodiment, after the connection and post-grouting process of the upper box module 100 and the lower box module 100 are completed, anti-leakage treatment needs to be performed.

[0066] Specifically, after the connection of the upper box module 100 and the lower box module 100 is completed, anti-leakage treatment is performed on the splicing part of the left and right adjacent box modules 100 to form an anti-leakage sealing structure 50. This step includes: first, cleaning the joint part that needs to be treated for anti-leakage to ensure that the surface is clean and free of impurities; second, applying anti-leakage sealing material at the connection according to the design requirements to ensure that the material is evenly and continuously applied and firmly bonded to the base layer; and finally, checking the quality of the anti-leakage treatment to ensure that there are no omissions and defects.

[0067] By adding the anti-leakage treatment step, rainwater and the like can be effectively prevented from seeping into the building from the module connection, the overall waterproof performance of the building is improved, and the service life of the building is prolonged.

[0068] By using the above construction method, the steel structure modular building room of the embodiments of the utility model can be ensured to have good implementation effect. The method is not only simple and convenient to operate and has high construction efficiency, but also can effectively ensure the construction quality, and provides reliable protection for the use safety of the building.

[0069] The above merely describes a specific implementation of the present application, but the scope of protection of the present application is not limited thereto, and any skilled person in the art can easily think of various equivalent modifications or replacements within the technical scope disclosed by the present application, and these modifications or replacements should be encompassed within the scope of protection of the present application. Therefore, the scope of protection of the present application should be subject to the scope of protection of the claims.
