Description

Prefabricated room module, building and construction method

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202310799735.4 and application date June 30, 2023, and claims the priority of the Chinese patent application. The entire content of the Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0003] The present invention relates to the field of building technology, and in particular to a prefabricated room module, a building and a construction method. Background Art

[0004] In existing technologies, modular building construction is common in steel or concrete structures. Specifically, there are two approaches: using steel columns and beams to form cubic steel frames as building modules, or using precast concrete walls and concrete floors to form cubic spaces as building modules, and then splicing these modules together to construct the building.

[0005] However, on the one hand, the steel structure system is not suitable for building high-rise buildings. On the other hand, it has poor consumer acceptance when used as a residential building. In addition, since the steel frame itself serves as a load-bearing structure, a large amount of steel is used in the construction. On the other hand, the concrete system is relatively inconvenient to transport and hoist due to the heavy weight of the concrete itself, and it severely limits the size of the building modules.

[0041] In a fourth aspect, an embodiment of the present invention further provides a construction method for a modular building as described above, comprising: placing all prefabricated room modules in place by hoisting, and gradually forming the modular building by pouring in-situ concrete during and after the hoisting process.

[0042] Optionally, all prefabricated room modules are placed in place by hoisting, and during and after the hoisting process, the prefabricated room modules that have been placed in place are gradually formed into the modular building by pouring concrete, including: constructing the prefabricated room modules floor by floor from bottom to top to build the modular building; wherein, the construction of the prefabricated room modules on each floor includes: using hoisting equipment to place the prefabricated room modules to be constructed in place; pouring concrete on the complete shear wall bodies in the prefabricated room modules that are placed in place to form shear walls; after the shear wall bodies of all the prefabricated room modules in the floor are formed into shear walls through concrete pouring, pouring concrete on the top plate bodies in all the prefabricated room modules in the floor to form the top plate of the floor.

[0043] Optionally, concrete is poured into the complete shear wall bodies in the prefabricated room modules that are placed in place to form shear walls, including: pouring concrete into the complete shear wall bodies in each prefabricated room module each time a prefabricated room module is hoisted and placed; when the local shear wall bodies at the connection between two horizontally adjacent prefabricated room modules are fixedly connected to form a complete shear wall body, concrete is poured into the complete shear wall body formed at the connection; or, all the prefabricated room modules on the same floor are hoisted and placed; the local shear wall bodies at the connection between the horizontally adjacent prefabricated room modules are fixedly connected to form a complete shear wall body; and concrete is poured into all the complete shear wall bodies on the floor.

[0044] In the solution provided by the first aspect of the embodiment of the present invention, the prefabricated room module provided by the embodiment of the present invention uses modular means to extract the prefabricated parts of the shear wall and the top plate, and completes the assembly in the factory to form a standard module self-loaded system, that is, a prefabricated room module, so that only the module needs to be hoisted and concrete poured on the construction site, and all or most of the small component hoisting, scaffolding and construction support erection work can be eliminated; and because the prefabricated room module has prefabricated the shear wall body and the top plate body in advance in the factory, the structural welding and bolt connection work of the shear wall body during on-site construction is reduced, and based on the fact that the shear wall body can limit the geometric shape of the shear wall, the embodiment of the present invention does not need to carry out on-site concrete formwork support and reinforcement. Binding and welding work; in addition, the prefabricated room module provided by the embodiment of the present invention, compared with the existing steel modularization technology, can reduce the amount of steel used and save construction costs because the combined structure is mainly used to bear the force after pouring concrete. Compared with the building modules of the concrete system, the prefabricated room module provided by the embodiment of the present invention is lighter and more conducive to lifting and transportation. Moreover, the prefabricated room module can complete the manufacturing of most structures (shear wall body and top plate body) in the factory, and the degree of mechanization of the factory and the site is greatly improved, thereby greatly reducing the number of construction personnel required on the construction site, while reducing the difficulty of on-site construction, improving the quality of building products, reducing construction site garbage, and maximizing green construction, reducing resource waste and environmental pollution.

[0045] In the solution provided in the second aspect of the embodiment of the present invention, because the prefabricated room modules used are manufactured in a factory, the quality of the modular building is well guaranteed, and the modular building is more standardized, making it more suitable for standardized building scenarios such as dormitories and hotels. In addition, because the modular building provided by the embodiment of the present invention is a steel-concrete composite structure, it can fully utilize the advantages of steel's high tensile strength and good plasticity and concrete's good compressive properties, compensating for their respective shortcomings. Not only does it have high load-bearing capacity and rigidity, but it also has good seismic resistance, fire resistance, and corrosion resistance. Compared to steel modular buildings, the modular building provided by the embodiment of the present invention mainly uses the composite structure to bear the load, which can further reduce steel usage and save construction costs.

[0046] In the solution provided in the third aspect of the embodiment of the present invention, the upper and lower prefabricated room modules are connected by using the steel structure edge members connected in the upper and lower prefabricated room modules. Based on the special setting structure of the top and bottom ends of the steel structure edge members, such as the inner core column and the sleeve assembly, the pull-out resistance between the two upper and lower connected steel structure edge members is improved after pouring concrete, and the two upper and lower adjacent prefabricated room modules can be better fixed.

[0047] In the solution provided in the fourth aspect of the embodiment of the present invention, the embodiment of the present invention transports the prefabricated room modules processed in the factory to the construction site by hoisting and placing them in place. During the hoisting process, concrete is poured in the wall cavities, pouring areas, and other areas of the prefabricated room modules to be poured with concrete. When multiple prefabricated room modules are spliced ​​together, after the prefabricated room modules to be spliced ​​are hoisted, concrete is poured in the splicing locations between the adjacent prefabricated room modules in place, thereby gradually forming a modular building. This construction method is based on the fact that the prefabricated room modules to be hoisted and transported are lightweight, which is more convenient for hoisting and transportation. Moreover, because this construction method is implemented for prefabricated room modules, only the hoisting and concrete pouring of the prefabricated room modules need to be performed on the construction site, which can eliminate all or most of the hoisting of small components, the erection of scaffolding and construction supports, and the need to support concrete formwork, tie steel bars, and weld on site. This can significantly reduce the number of construction workers required on the construction site, while reducing the difficulty of on-site construction and improving construction speed and efficiency.

[0083] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0084] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0085] An embodiment of the present invention provides a prefabricated room module, as shown in Figure 1, which includes: a shear wall body 1 and a top plate body 2; the shear wall body 1 has a wall cavity 10 for cast-in-place concrete, and a shear wall is formed after concrete is poured into the wall cavity 10, and the geometric shape of the shear wall is defined by the shear wall body 1; the top plate body 2 has a pouring area 20 for cast-in-place concrete, and a top plate is formed after concrete is poured into the pouring area 20, and the geometric shape of the top plate is defined by the top plate body 2; the shear wall body 1 is fixedly connected to the top plate body 2.

[0086] The embodiment of the present invention belongs to a modular building system. It is necessary to process the prefabricated parts of the building modules in advance in the factory, and then transport the prefabricated parts of the building modules to the construction site by hoisting for cast-in-place to form the final building structure. In the embodiment of the present invention, the prefabricated parts of the building modules are referred to as prefabricated room modules. Among them, the prefabricated room module includes a shear wall body 1 and a top plate body 2. As shown in Figure 1, the upper end of the shear wall body 1 is fixedly connected to the side edge of the top plate body 2 to form a self-loaded system. For example, the shear wall body 1 and the top plate body 2 can be fixedly connected by welding.

[0087] The shear wall body 1 is a prefabricated portion of the shear wall in the building structure that is ultimately formed at the construction site, and the specific geometric shape of the ultimately formed shear wall is directly determined by the shear wall body 1. That is, the shear wall body 1 is a shear wall that has not yet been poured with concrete. The specific shape of the shear wall formed after the concrete is poured into the shear wall body 1 is consistent with the original specific shape of the shear wall body 1. For example, if the shape of the shear wall body 1 is rectangular, the shape of the shear wall obtained after the concrete is finally poured is also rectangular. Specifically, the shear wall body 1 includes a wall cavity 10, which is used to accommodate the concrete poured into the shear wall body 1 at the construction site so that the shear wall body 1 forms a shear wall. The number of shear wall bodies 1 can be one or more. For example, a prefabricated room module can include four shear wall bodies 1, and the four shear wall bodies 1 can be enclosed to form a module with closed sides. Alternatively, the prefabricated room module can include only three shear wall bodies 1, and the three shear wall bodies 1 can form a module with open sides.

[0088] Accordingly, the top plate body 2 is the prefabricated part of the top plate in the building structure that is ultimately formed at the construction site. For example, the top plate body 2 can be a prefabricated floor plate to be poured with concrete, specifically, a prefabricated concrete composite floor plate, a prefabricated prestressed concrete composite floor plate, a prefabricated prestressed ribbed concrete composite floor plate, a prestressed concrete steel tube truss composite floor plate, or the like. Moreover, the specific geometric shape of the top plate that is ultimately formed is directly defined by the top plate body 2. That is, the top plate body 2 is a top plate that has not yet been poured with concrete. The specific shape of the top plate formed after the concrete is poured into the top plate body 2 is consistent with the original specific shape of the top plate body 2. For example, the shape of the top plate body 2 is rectangular, and the shape of the top plate obtained after the concrete is finally poured is also rectangular. Specifically, the top plate body 2 has a pouring area 20, which is used to accommodate the concrete poured into the top plate body 2 at the construction site so that the top plate body 2 forms a top plate.

[0089] The prefabricated room module provided by the embodiment of the present invention uses modular means to extract the prefabricated parts of the shear wall and the top plate, and completes the assembly in the factory to form a standard module self-loaded system, that is, a prefabricated room module. Therefore, at the construction site, only the module needs to be hoisted and concrete poured, and all or most of the small component hoisting, scaffolding and construction support erection work can be eliminated; and because the prefabricated room module has prefabricated the shear wall body 1 and the top plate body 2 in advance in the factory, the structural welding and bolt connection work of the shear wall body 1 during on-site construction is reduced, and based on the fact that the shear wall body 1 can define the geometric shape of the shear wall, the embodiment of the present invention does not need to carry out on-site concrete formwork support, steel bar binding and welding work; this In addition, compared with the existing steel modularization technology, the prefabricated room module provided by the embodiment of the present invention can reduce the amount of steel used and save construction costs because the combined structure is the main load-bearing element after pouring concrete. Compared with the building modules of the concrete system, the prefabricated room module provided by the embodiment of the present invention is lighter and more conducive to lifting and transportation. Moreover, the prefabricated room module can complete the manufacturing of most structures (shear wall body 1 and top plate body 2) in the factory, greatly improving the degree of mechanization in the factory and on-site, thereby greatly reducing the number of construction personnel required on the construction site, reducing the difficulty of on-site construction, improving the quality of building products, reducing construction site garbage, and maximizing green construction, reducing resource waste and environmental pollution.

[0090] Optionally, as shown in FIG. 2 , the shear wall body 1 includes at least an inner membrane shell 11 and an outer membrane shell 12 that are arranged opposite to and in parallel; the cavity between the inner membrane shell 11 and the outer membrane shell 12 is the wall cavity 10 .

[0091] In an embodiment of the present invention, when the shear wall formed by pouring concrete on the shear wall body 1 is the exterior wall of the building, the inner membrane shell 11 of the shear wall body 1 is located on the side of the shear wall facing the interior, and the outer membrane shell 12 of the shear wall body 1 is located on the side of the shear wall facing the exterior, and the inner membrane shell 11 and the outer membrane shell 12 are arranged opposite to and in parallel, and the cavity between the two is the wall cavity 10 of the shear wall body 1. That is to say, the concrete poured on the shear wall body 1 at the construction site will be poured between the inner membrane shell 11 and the outer membrane shell 12 of the shear wall body 1.

[0092] Because the inner membrane shell 11 and the outer membrane shell 12 included in the shear wall body 1 can be used as wall side panels in the module production and hoisting stages and as templates in the construction stage, the prefabricated room module provided by the embodiment of the present invention can not only improve the module rigidity in the production and transportation stages, but also avoid the on-site shear wall reinforcement binding and template support work, saving construction steps and construction personnel.

[0093] Optionally, as shown in Figure 3, the height of the outer membrane shell 12 is higher than the height of the inner membrane shell 11; the top plate body 2 is fixedly connected to the inner membrane shell 11, so that any wall cavity 10 is connected to the pouring area 20 to form a connecting area. After the connecting area is poured with concrete, any shear wall is connected to the top plate as a whole.

[0094] Among them, the heights of the inner membrane shell 11 and the outer membrane shell 12 of the shear wall body 1 are different, that is, there is a height difference between the two. Specifically, the height of the outer membrane shell 12 is higher than the height of the inner membrane shell 11, and one side edge of the top plate body 2 can be fixed and connected to the inner membrane shell 11 to form an integral structure. As shown in Figure 3, one side edge of the top plate body 2 is placed on the upper end of the inner membrane shell 11, and the two are fixedly connected by welding, so that the top plate body 2 and the shear wall body 1 are connected to form an integral structure; or, one side edge of the top plate body 2 can be inserted into the inner membrane shell 11, and the two are fixedly connected by welding, so that the top plate body 2 and the shear wall body 1 are connected to form an integral structure. Furthermore, the upper opening of the wall cavity 10 formed between the inner membrane shell 11 and the outer membrane shell 12 (as shown at P in Figure 3) can be connected to the edge of the pouring area 20 of the top plate body 2 to form a connecting area, so that the two areas for pouring concrete (the wall cavity 10 and the pouring area 20) form an integral area for pouring concrete. After the concrete pouring construction of the connecting area is completed, the obtained shear wall and the top plate can be connected into an integrated structure.

[0095] For example, when four shear wall bodies 1 are enclosed to form a rectangle, the upper ends of the inner membrane shells 11 in the four shear wall bodies 1 are respectively welded to the four edges of the top plate body 2, so that the pouring area 20 of the top plate body 2 is respectively connected to the wall cavity 10 of the four shear wall bodies 1 to form a connecting area. When the connecting area is poured with concrete, the four shear walls are connected to the top plate as one.

[0096] In an embodiment of the present invention, the outer membrane shell 12 and the inner membrane shell 11 of the shear wall body 1 are set to different heights, and the outer membrane shell 12 is higher than the inner membrane shell 11, so that the part of the outer membrane shell 12 that is higher than the inner membrane shell 11 can be used as a block when pouring concrete of the top plate body 2 after the inner membrane shell 11 is fixedly connected to the top plate body 2. After the concrete inside the wall cavity 10 is poured to form a shear wall, concrete is continued to be poured in the pouring area 20 in the connected area that has been connected into one, thereby improving the construction smoothness of the concrete pouring stage.

[0097] Optionally, as shown in Figure 4, the outer membrane shell 12 is at the same height as the inner membrane shell 11; the bottom surface of the top plate body 2 is set at a height lower than the height of the inner membrane shell 11, and the part of the inner membrane shell 11 that is higher than the bottom surface of the top plate body 2 forms a pouring area 20 with the bottom surface of the top plate body 2.

[0098] Among them, the inner membrane shell 11 and the outer membrane shell 12 of the shear wall body 1 have the same height, and one side edge of the bottom surface of the top plate body 2 can be fixedly connected to the inner membrane shell 11, so that the shear wall body 1 and the top plate body 2 form an integral structure. For example, one side edge of the bottom surface of the top plate body 2 is inserted into the inner membrane shell 11, and the two are fixedly connected by welding.

[0099] In an embodiment of the present invention, the portion of the inner membrane shell 11 that is higher than the bottom surface of the top plate body 2 and the bottom surface of the top plate body 2 can form a pouring area 20 for the subsequent pouring of top plate concrete, that is, the portion of the inner membrane shell 11 that is higher than the bottom surface of the top plate body 2 can serve as a blockade for the pouring area 20, so that the wall cavity 10 and the pouring area 20 are two separated areas. When pouring concrete for the prefabricated room module, you can first specifically select concrete that is more suitable for pouring the shear wall body 1 and pour it into the wall cavity 10, and then specifically select concrete that is more suitable for pouring the top plate body 2 and pour it into the pouring area 20, so as to better realize the pouring of concrete in different areas and further save construction costs. For example, you can first pour C40 concrete or C50 concrete into the wall cavity 10 to obtain a shear wall, and then pour C30 concrete into the pouring area 20 to obtain a top plate.

[0100] Optionally, as shown in FIG. 5 , the top plate body 2 includes: a bottom formwork steel plate 21 and a steel bar truss 22 .

[0101] The bottom formwork steel plate 21 can be a 1.5 mm thick steel plate, and the lower surface of the bottom formwork steel plate 21 is the bottommost surface of the top plate body 2; the steel truss 22 is welded to the upper surface of the bottom formwork steel plate 21, and the bottom formwork steel plate 21 and the inner membrane shell 11 can be fixedly connected by welding, so that the upper surface of the bottom formwork steel plate 21 and the steel truss 22 are located inside the pouring area 20 of the top plate body 2. The embodiment of the present invention uses the prefabricated part of the assembled floor slab as the top plate body 2 to ensure that the top plate body 2 can be supported during the construction and pouring of concrete.

[0102] Optionally, when the height of the outer membrane shell 12 is higher than that of the inner membrane shell 11, the bottom formwork steel plate 21 is overlapped on the inner membrane shell 11. For example, one edge of the bottom formwork steel plate 21 can be overlapped on the upper end of the inner membrane shell 11, and the two can be fixedly connected by welding, so that the top plate body 2 and the shear wall body 1 are connected to form an integrated structure.

[0103] Optionally, when the outer membrane shell 12 and the inner membrane shell 11 are at the same height, the bottom formwork steel plate 21 is connected to the side wall of the inner membrane shell 11. For example, one edge of the bottom formwork steel plate 21 can be inserted into the side wall of the inner membrane shell 11, and the two can be fixedly connected by welding, so that the top plate body 2 and the shear wall body 1 are connected to form an integrated structure.

[0104] Optionally, referring to FIG. 1 or FIG. 2 , the shear wall body 1 further includes: a shear wall steel frame 13 ; the shear wall steel frame 13 is fixedly connected in the wall cavity 10 .

[0105] Optionally, the shear wall body 1 further includes: a first connecting member; one side of the shear wall steel frame 13 is fixedly connected to the inner membrane shell 11 through the first connecting member, and the other side of the shear wall steel frame 13 is fixedly connected to the outer membrane shell 12 through the first connecting member.

[0106] Among them, in addition to the inner membrane shell 11 and the outer membrane shell 12 arranged relatively and in parallel, the shear wall body 1 also has a shear wall steel skeleton 13 fixedly arranged inside the wall cavity 10 formed between the inner membrane shell 11 and the outer membrane shell 12. Furthermore, the shear wall steel skeleton 13 can be connected to the inner membrane shell 11 and the outer membrane shell 12 respectively through a first connecting member, so that the shear wall body 1 forms a "sandwich" structure, that is, one side of the shear wall steel skeleton 13 is connected to the inner membrane shell 11 through the first connecting member, and the other side is also connected to the outer membrane shell 12 through the first connecting member, forming an overall structure with a non-disassembly formwork. Among them, the first connecting member can include self-tapping screws, angle steel, channel steel or flat steel plate, etc.

[0107] Optionally, as shown in FIG. 2 , the shear wall steel skeleton 13 includes a steel cage 131 and steel structure edge members 132 vertically fixedly connected to both ends of the steel cage 131 in the longitudinal direction.

[0108] In the embodiment of the present invention, the length direction of the steel cage 131 is the lateral extension direction of the shear wall body 1, and steel structure edge members 132 are vertically fixedly connected to both ends of the length direction of the steel cage 131. Specifically, the two ends of the length direction of the steel cage 131 can be fixedly connected to the surface of the steel structure edge member 132 by welding, or, as shown in Figure 6, the steel cage 131 and the steel structure edge member 132 can also be connected by an additional steel structure member Z, which is used to adjust the size of the part of the prefabricated room module. For example, when the length of the steel cage 131 is not enough, the additional steel structure member Z can be used to fix the steel cage 131 to the steel structure edge member 132. In the embodiment of the present invention, the steel structure edge members 132 provided at both ends of the steel cage 131 constitute both the two ends of the shear wall steel skeleton 13 and the two ends of the shear wall body 1. The steel structure edge member 132 can be a steel column or an I-beam, etc.

[0109] Among them, since the shear wall steel frame 13 is arranged in the wall cavity 10 composed of the inner membrane shell 11 and the outer membrane shell 12, the steel structure edge member 132, as a part of the shear wall steel frame 13, is also arranged in the wall cavity 10 composed of the inner membrane shell 11 and the outer membrane shell 12. For details, please refer to Figure 2. The side surface of the steel structure edge member 132 close to the inner membrane shell 11 is fixedly connected to the inner membrane shell 11, and the side surface of the steel structure edge member 132 close to the outer membrane shell 12 is fixedly connected to the outer membrane shell 12. In addition, the steel cage 131 is also part of the shear wall steel skeleton 13 and is also arranged in the wall cavity 10 formed by the inner membrane shell 11 and the outer membrane shell 12, wherein the side surface of the steel cage 131 close to the inner membrane shell 11 is fixedly connected to the inner membrane shell 11, and the side surface of the steel cage 131 close to the outer membrane shell 12 is fixedly connected to the outer membrane shell 12. For example, the fixed connection method may include: welding, bolt connection or self-tapping screw connection, etc. The embodiment of the present invention does not specifically limit the above-mentioned fixed connection method.

[0110] Optionally, as shown in Figure 6, the steel cage 131 includes: a tie bar 1311 and two layers of oppositely and parallelly arranged steel meshes 1312; the tie bar 1311 is arranged between the two layers of steel meshes 1312, and is used to tie the steel meshes 1312 on both sides; the two ends of the steel mesh 1312 are fixedly connected to the steel structure edge members 132.

[0111] In this embodiment of the present invention, the two sides of the steel cage 131, which are fixedly connected to the inner membrane shell 11 and the outer membrane shell 12, respectively, are formed with two layers of opposing and parallel steel mesh 1312. Tie bars 1311 are used to connect the two layers of steel mesh 1312. As shown in Figure 6, the tie bars 1311 can be connected in a Z-shaped pattern to prevent mold expansion during concrete pouring. Furthermore, the ends of the steel mesh 1312 are fixedly connected to the steel structure edge members 132 located at the longitudinal ends of the steel cage 131 by welding.

[0112] Optionally, the steel mesh includes: horizontal steel bars and vertical keels; a plurality of parallel horizontal steel bars are fixedly connected to a plurality of parallel vertical keels to form the steel mesh.

[0113] The steel mesh is formed by a plurality of mutually parallel horizontal steel bars and a plurality of mutually parallel vertical keels that are perpendicularly crossed to form a steel mesh (as shown in FIG2 ). Specifically, the plurality of mutually parallel horizontal steel bars are arranged on the same side of the plurality of mutually parallel vertical keels, so that the side of the vertical keel away from the horizontal steel bars can be fixedly connected to the inner membrane shell 11 or the outer membrane shell 12. For example, the vertical keel can be an angle steel, a channel steel, a flat steel plate or a square steel bar. When the vertical keel is a C-shaped channel steel, the open side of the vertical keel can be fixedly connected to the horizontal steel bar, and the flat side of the vertical keel can be fixedly connected to the outer membrane shell 12 or the inner membrane shell 11. The method of fixing the vertical keel to the membrane shell can include: bolt connection or self-tapping screw connection.

[0114] Optionally, as shown in Figure 7, the steel structure edge member 132 includes: a steel column 1321, an inner core column 1322 and a sleeve assembly 1323; the steel column 1321 includes relative bottom and top ends, and the sleeve assembly 1323 is fixedly connected to the bottom end of the steel column 1321, and is used to be sleeved with the inner core column 1322 of the adjacent prefabricated room module on the lower floor; the inner core column 1322 is fixedly connected to the top of the steel column 1321, and the inner core column 1322 protrudes from the top of the steel column 1321, and is used to insert the sleeve assembly 1323 of the adjacent prefabricated room module on the upper floor to form a nest.

[0115] Among them, the steel column 1321 is a hollow long strip structure, the cross-sectional width of the inner core column 1322 is smaller than the cross-sectional width of the steel column 1321, and the cross-sectional width of the sleeve component 1323 is the same as the cross-sectional width of the steel column 1321. The sleeve component 1323 can be fixedly connected to the bottom end of the steel column 1321 by welding; further, the sleeve component 1323 fixedly connected to the bottom of the steel column 1321 in the prefabricated room module located on the upper floor can be nested with the inner core column 1322 fixedly connected to the top of the steel column 1321 in the adjacent prefabricated room module located on the lower floor, so that the two adjacent prefabricated room modules are fixed.

[0116] Optionally, as shown in Figure 8, the sleeve assembly 1323 includes: a steel column body 001 with multiple welding grooves 002 opened on the side wall, and an anti-pull-out connection assembly 003; the anti-pull-out connection assembly 003 is fitted on the inner wall of the steel column body 001, and the anti-pull-out connection assembly 003 and the steel column body 001 are welded and fixed at the welding groove 002 position.

[0117] When two upper and lower adjacent prefabricated room modules are vertically connected by a steel structure edge member 132, in order to enhance the pull-out resistance between the two upper and lower adjacent steel structure edge members 132, an embodiment of the present invention sets a pull-out resistance connection component 003 on the inner side wall of the steel column body 001, and welds the pull-out resistance connection component 003 to the multiple welding grooves 002 opened on the side wall of the steel column body 001 from the outside. Specifically, during welding, the pull-out resistance connection component 003 is welded and fixed to the steel column body 001 from the position of the welding groove 002 on the outer side wall of the steel column body 001, such as spot welding, so that the inner side wall of the steel column body 001 forms a pull-out resistance structure with a concave and convex shape, and at the same time facilitates the welding operation, greatly improves the convenience of welding, thereby increasing the welding speed, improving production efficiency, and facilitating the realization of automated production.

[0118] Alternatively, as shown in FIG8 , one side of the anti-pullout connection assembly 003 has a concave-convex shape to form multiple anti-pullout structures extending along a predetermined direction. The side of the anti-pullout connection assembly 003 facing away from the anti-pullout structures is attached to the inner sidewall of the steel column body 001. The predetermined direction forms an angle with the axial direction of the steel column body 001. The extending direction of the anti-pullout structures provided on the anti-pullout connection assembly 003 forms an angle with the axial direction of the steel column body 001. This means that when the sleeve assembly 1323 is in use, the anti-pullout structures are not arranged vertically.

[0119] Further, referring to Figure 9, a schematic diagram of a first embodiment of a pull-out resistant connection assembly 003 is shown. The pull-out resistant connection assembly 003 comprises a steel plate 011 and a steel bar 010. The steel bar 010 is welded to the inner sidewall of the steel column body 001 via the steel plate 011. Multiple steel bars 010 are present. The steel plate 011 includes a first side surface and a second side surface facing each other. Multiple steel bars 010 are welded to the first side surface of the steel plate 011 in sequence and at intervals. The multiple steel bars 010 extend along a predetermined direction X to form a pull-out resistant structure. The multiple steel bars 010 are welded to the steel plate 011 to form a single piece. The second side surface of the steel plate 011 is then attached to the inner sidewall of the steel column body 001. Finally, welding is performed from the welding groove 002 on the outer sidewall of the steel column body 001.

[0120] Steel plate 011 can be a thin-walled steel plate, its shape matching the inner sidewall of steel column body 001, for example, a rectangular structure. Multiple steel bars 010 are spaced apart in sequence, forming a concave and convex tensile-resistant structure on the first side of steel plate 011. Multiple steel bars 010 are evenly welded to the first side of steel plate 011, and each steel bar 010 extends along a predetermined direction X. Multiple steel bars 010 are sequentially distributed in a direction perpendicular to predetermined direction X.

[0121] In the embodiment of the present invention, the shape of the steel bar 010 welded to the steel plate 011 is not limited and may be a wavy structure, an arc structure, a long straight structure, a long diagonal structure, a special-shaped structure, or a bent structure. When the steel bar 010 has a bent structure, it may include a first segment and a second segment connected to each other, with the first segment and the second segment forming an angle. This application does not limit the specific shape of the steel bar 010, as long as it is welded to the steel plate 011 and extends as a whole along a predetermined direction X, so that the first side surface of the steel plate 010 forms a concave-convex structure, thereby providing a pull-out resistance effect. Referring to Figure 10, Figure 10 shows a schematic diagram of a second structure of the pull-out resistance connection assembly 003, wherein the pull-out resistance connection assembly 003 may include a steel plate 011, the steel plate 011 including a first side surface and a second side surface facing away from each other, the first side surface being provided with a plurality of ridges 012 extending along the predetermined direction X to form a pull-out resistance structure. During installation, the second side surface of the steel plate 011 is attached to the inner side wall of the steel column body 001 for welding. The ridge 012 and the steel plate 011 may be integrally formed, for example, by die casting, or extrusion molding, etc., which is not limited in the present embodiment.

[0122] In other optional embodiments, multiple grooves may be sequentially and spaced apart on the first side surface of the steel plate 011, extending along a predetermined direction X, with a raised rib 012 formed between any two adjacent grooves. Preferably, the width of the grooves on the first side surface of the steel plate 011 can be significantly greater than the height, and can be formed using a milling process. Specifically, multiple grooves are milled into a flat plate, such that any two adjacent grooves are separated by a raised rib 012.

[0123] Referring to FIG. 11 , FIG. 11 shows a schematic diagram of a third structure of the pull-out resistant connection assembly 003 , wherein the pull-out resistant connection assembly 003 is a frame structure and may include cross-beams 004 and longitudinal beams 013 arranged in a crosswise manner. During installation, the longitudinal beams 013 are parallel to the axis of the steel column body 001 , and the cross beams 004 extend along a preset direction X to form a pull-out resistant structure. Furthermore, the number of longitudinal beams 013 may be at least two, and the number of cross beams 004 may be multiple. At least two longitudinal beams 013 extend along the axial direction of the steel column body 001 , and the multiple cross beams 004 are arranged in sequence at intervals, with the ends of the cross beams 004 respectively connected to the outermost longitudinal beams 013 . For example, in the structure shown in FIG. 5 , there are two longitudinal beams 013 , each located at the outermost side, and the multiple cross beams 004 are evenly spaced and arranged between the two longitudinal beams 013 .

[0124] During installation, the anti-pullout connection component 003 of the frame structure is set on the inner wall of the steel column body 001, but it should be noted that the welding groove 002 opened on the steel column body 001 must correspond to the crossbeam 004 of the frame structure to facilitate welding.

[0125] Furthermore, the welding groove 002 opened on the side wall of the steel column body 001 can be a strip groove, a circular groove, an arc groove or a broken line groove, etc. The present application does not limit the shape, size, position, etc. of the welding groove 002. As long as it meets the production welding requirements, the steel column body 001 can be welded and fixed to the anti-pull-out connection component 003 through the welding groove 002 from the outer wall of the steel column body 001.

[0126] Among them, the shape of the beam 004 can be a bent, wavy, arc-shaped or long straight-line structure. The present application does not limit the specific shape of the beam 004. As long as it extends as a whole along the preset direction X, the anti-pullout connection component 003 is welded to the inner wall of the steel column body 001, so that the inner side of the steel column body 001 forms a concave-convex structure with an anti-pullout effect.

[0127] In this embodiment of the present application, to improve the pullout resistance between the steel structural edge members 132 of two adjacent prefabricated room modules, a pullout-resistant connection assembly 003 can be provided on each inner sidewall of the steel column body 001. That is, the steel column body 001 includes multiple inner sidewalls, each of which is attached with an pullout-resistant connection assembly 003, thereby enhancing pullout resistance from all sides.

[0128] Optionally, as shown in Figures 12 and 13, the pull-out resistant connection assembly 003 is a hollow cylindrical structure, including multiple beams 004 extending along a preset direction; the welding groove 002 corresponds to at least part of the beams 004, and the preset direction has an angle with the axial direction of the steel column body 001.

[0129] During installation, the anti-pullout connection assembly 003 is embedded within the steel column body 001, with the axial direction of the steel column body 001 being aligned with the axial direction of the anti-pullout connection assembly 003. The welding groove 002 of the steel column body 001 is aligned with at least a portion of the crossbeam 004 of the anti-pullout connection assembly 003. The crossbeam 004 is welded to the steel column body 001 at the welding groove 002 from the outside of the steel column body 001, thereby securing the anti-pullout connection assembly 003 to the steel column body 001. After welding, the crossbeam 004 of the anti-pullout connection assembly 003 protrudes from the inner sidewall of the steel column body 001, forming an anti-pullout structure with a concave-convex shape. It is understood that in order to improve the anti-pullout performance, the extension direction of the anti-pullout structure provided on the sleeve assembly 1323 forms an angle with the axial direction of the sleeve assembly 1323. That is, when the sleeve assembly 1323 is in use, the crossbeam 004 is not arranged vertically, but extends horizontally or in an inclined direction.

[0130] Further, referring to FIG14 , FIG14 shows a schematic diagram of the fourth structure of the anti-pull-out connection assembly 003, wherein the anti-pull-out connection assembly 003 further includes a vertical beam 014, which is cross-connected with the horizontal beam 004 and encloses a hollow columnar structure. Specifically, the vertical beam 014 extends along the axial direction Y, and the number of vertical beams 014 is multiple, and the multiple vertical beams 014 are parallel but not located on the same plane. The horizontal beam 004 is connected between two adjacent vertical beams 014, and the two adjacent vertical beams 014 and the horizontal beam 004 located therebetween form a plane, and the multiple planes form a hollow columnar structure. Among them, the vertical beam 014 extends along the axial direction Y, and the horizontal beam 004 extends along the preset direction X, and the axial direction Y and the preset direction X have an angle.

[0131] Furthermore, multiple crossbeams 004 are disposed between any two adjacent vertical beams 014, and the crossbeams 004 between any two adjacent vertical beams 014 are sequentially spaced along the axial direction Y. As shown in FIG14 , there are four vertical beams 014, which are arranged in parallel. The crossbeams 004 connect between two adjacent vertical beams 014, forming a rectangular frame structure. Two adjacent vertical beams 014 and the crossbeams 004 between them form a side wall. The crossbeams 004 on each side wall extend along a predetermined direction X, and the crossbeams 004 are sequentially spaced along the axial direction Y.

[0132] Specifically, the preset direction X can be perpendicular to the axial direction Y. That is, in the structure shown in Figure 14, when in use, all horizontal beams 004 extend horizontally, and all vertical beams 014 extend vertically. In an optional embodiment of the present application, the multiple horizontal beams 004 provided between any two adjacent vertical beams 014 are evenly spaced. In order to improve the pull-out resistance between the steel structure edge members 132 of the upper and lower prefabricated room modules, the gap between the horizontal beams 004 on each side wall of the sleeve assembly 1323 should not be too small. Specifically, the spacing between two adjacent horizontal beams 004 is greater than or equal to the width of the horizontal beam 004.

[0133] As shown in Figures 12 and 15 , in an optional embodiment of the present application, the cross-sectional shape of the pull-out-resistant connection assembly 003 is the same as that of the steel column body 001, both being rectangular. Each sidewall of the steel column body 001 is uniformly provided with a plurality of welding slots 002. The number of welding slots 002 is the same as the number of crossbeams 004, and the multiple welding slots 002 are arranged in a one-to-one correspondence with the multiple crossbeams 004. By welding at the welding slots 002, each crossbeam 004 is secured to the steel column body 001, thereby improving the strength of the sleeve assembly 1323 while still maintaining pull-out resistance.

[0134] In order to facilitate the embedding of the anti-pull-out connection component 003 into the steel column body 001, the maximum cross-sectional length dimension a1 of the anti-pull-out connection component 003 should be smaller than the minimum cross-sectional length dimension a2 of the steel column body 001, and the maximum cross-sectional width dimension b1 of the anti-pull-out connection component 003 should be smaller than the minimum cross-sectional width dimension b2 of the steel column body 001.

[0135] To ensure welding quality, the distance between the outer wall of the pull-out-resistant connection assembly 003 and the inner wall of the steel column body 001 can optionally be greater than or equal to 1 mm and less than or equal to 5 cm. That is, a2-a1 is greater than or equal to 1 mm and less than or equal to 5 cm; and b2-b1 is greater than or equal to 1 mm and less than or equal to 5 cm. In other words, the gap between the pull-out-resistant connection assembly 003 and the steel column body 001 should not be too large. If the gap is too large, it will not only be difficult to weld and secure, but also difficult to ensure stability after welding. Of course, the gap between the pull-out-resistant connection assembly 003 and the steel column body 001 should also not be too small. If the gap is too small, the pull-out-resistant connection assembly 003 will not be easily embedded in the steel column body 001. This application does not limit the distance between the anti-pull-out connection component 003 and the steel column body 001, as long as the anti-pull-out connection component 003 can be embedded in the steel column body 001, and the crossbeam 004 of the anti-pull-out connection component 003 can be fixed to the steel column body 001 by welding from the outside of the steel column body 001.

[0136] To further enhance the connection stability between the pull-out resistant connection assembly 003 and the steel column body 001, in addition to welding at the weld groove 002, the ends of the pull-out resistant connection assembly 003 and the ends of the steel column body 001 can also be welded. For example, a weld can be provided at the connection between the outer wall of the end of the pull-out resistant connection assembly 003 and the inner wall of the end of the steel column body 001. In other words, the outer wall of the end of the pull-out resistant connection assembly 003 is chamfered, and / or the inner wall of the end of the steel column body 001 is chamfered.

[0137] Referring to FIG. 16 , FIG. 16 illustrates a fifth configuration of a pullout-resistant connection assembly 003. The pullout-resistant connection assembly 003 comprises a rectangular steel plate having multiple through-slots 015 extending along a predetermined direction X, such that a crossbeam 004 is formed between adjacent through-slots 015. The rectangular steel plate is bent multiple times along the predetermined direction X and welded end-to-end to form a hollow columnar structure. The hollow rectangular columnar structure can be formed by bending the rectangular steel plate having multiple through-slots 015, for example, three times, forming a right angle between adjacent sides, and welding the first and fourth sides end-to-end.

[0138] Then, the anti-pull-out connection component 003 is embedded in the steel column body 001, and the welding groove 002 opened on the steel column body 001 is staggered with the through groove 015 on the anti-pull-out connection component 003, that is, the welding groove 002 corresponds to the crossbeam 004, and at the position of the welding groove 002, the crossbeam 004 and the steel column body 001 are welded from the outside of the steel column body 001.

[0139] Optionally, as shown in FIG17 , the outer wall of inner core column 1322 is provided with a ridge 005 extending in a predetermined direction, which is angled with the axial direction of steel column body 001. After the steel structure edge members 132 of adjacent prefabricated room modules are joined and cemented, the pull-out resistance of the steel structure edge members 132 of the adjacent prefabricated room modules can be effectively enhanced by the ridge 005 on the outer wall of inner core column 1322 and the pull-out resistance of the inner wall of sleeve assembly 1323.

[0140] Optionally, as shown in Figures 18 to 20, the lower ends of the opposite side walls of the inner core column 1322 are provided with a first plug-in slot 006, and the upper ends of the opposite side walls of the steel column 1321 are provided with a second plug-in slot 007; the steel structure edge member 132 also includes: a plug-in plate 1324; the plug-in plate 1324 is used to insert into the first plug-in slot 006 and the second plug-in slot 007, so that the inner core column 1322 is fixedly connected to the steel column 1321.

[0141] Optionally, as shown in FIG. 21 and FIG. 22 , a positioning cone 008 is provided on the top of the inner core column 1322 , and a positioning cavity 009 for accommodating the positioning cone 008 is provided on the inner wall of the sleeve assembly 1323 .

[0142] In this embodiment of the present invention, a steel structure with an upward-pointing corner, namely, a positioning cone 008, can be fixed to the top of the inner core column 1322. Accordingly, a corresponding accommodating cavity, namely, a positioning cavity 009, is provided on the inner sidewall of the sleeve assembly 1323 to accommodate the positioning cone 008. Specifically, the positioning cavity 009 is an upwardly concave structure capable of receiving the positioning cone 008. A hole can be provided at the highest point of the positioning cavity 009, allowing the positioning cone 008 to align with the hole and further secure the positioning cone 008 in the hole. The positioning cavity 009 has a smooth surface and can be made of steel. This facilitates the alignment of the steel edge members 132 of two adjacent prefabricated room modules when they are connected. The positioning cone 008 at the top of the inner core column 1322 of the lower prefabricated room module cooperates with the positioning cavity 009 at the bottom inner side of the sleeve assembly 1323 of the upper prefabricated room module to position the two adjacent prefabricated room modules, thereby more accurately and quickly completing the splicing of the two layers of prefabricated room modules.

[0143] Optionally, refer to Figure 23, which shows a top view of the inner core column 1322; wherein, limiting steel bars 016 are inserted into the outer wall surfaces of the diagonal top corners of the inner core column 1322, and the limiting steel bars 016 are arranged diagonally along the extension direction of the diagonal line in the cross section of the inner core column 1322.

[0144] In an embodiment of the present invention, limiting steel bars 016 can be set on one or two pairs of diagonal outer walls of the inner core column 1322. As shown in Figure 23, limiting steel bars 016 are set on a pair of diagonal outer walls of the inner core column 1322 shown in Figure 23. By coordinating the limiting steel bars 016 set on the inner core column 1322 of the lower prefabricated room module with the sleeve assembly 1323 of the upper prefabricated room module, for example, the limiting steel bars 016 are made to fit the inner wall of the sleeve assembly 1323 of the upper prefabricated room module, thereby limiting the two adjacent prefabricated room modules above and below, thereby completing the splicing of the upper and lower prefabricated room modules more accurately and quickly.

[0145] Optionally, as shown in FIG1 , the prefabricated room module further comprises: a connecting beam body 3 , the connecting beam body 3 having a connecting beam cavity 30 for cast-in-place concrete, and a connecting beam is formed after concrete is poured into the connecting beam cavity 30 , the geometric shape of the connecting beam being defined by the connecting beam body 3 .

[0146] In the case where a connecting beam is required in the final building structure, for example, when doors and windows are provided in the prefabricated room module (as shown in FIG1 ), or when two shear wall bodies 1 are contained in the same plane and need to be connected, the prefabricated room module may further include a connecting beam body 3. The connecting beam body 3 is a prefabricated portion of the connecting beam in the building structure finally formed at the construction site, and the specific geometric shape of the connecting beam finally formed is directly defined by the connecting beam body 3. That is, the connecting beam body 3 is a connecting beam that has not yet been poured with concrete. The specific shape of the connecting beam formed after the concrete is poured into the connecting beam body 3 is consistent with the original specific shape of the connecting beam body 3. For example, the shape of the connecting beam body 3 is rectangular, and the shape of the connecting beam obtained after the concrete is poured is also rectangular. Specifically, the connecting beam body 3 includes a connecting beam cavity 30. The connecting beam cavity 30 is used to accommodate the concrete poured into the connecting beam body 3 at the construction site so that the connecting beam body 3 forms a connecting beam.

[0147] Optionally, as shown in Figure 24, the connecting beam body 3 includes: a connecting beam membrane shell 31, a connecting beam steel cage 32, a connecting beam bottom steel plate 33 and a connecting beam vertical keel 34; the two outer sides of the connecting beam steel cage 32 are fixedly connected to the connecting beam vertical keel 34, and the connecting beam steel cage 32 is fixedly connected to the inside of the connecting beam membrane shell 31 through the connecting beam vertical keel 34, and the inside of the connecting beam membrane shell 31 is a connecting beam cavity 30; the two ends of the connecting beam steel cage 32 in the length direction and the two ends of the connecting beam bottom steel plate 33 in the length direction are respectively fixedly connected to the shear wall body 1 connected to the two ends of the connecting beam body 3, and the connecting beam bottom steel plate 33 is fixedly connected to the bottom of the connecting beam vertical keel 34.

[0148] As shown in Figure 24, the interior of the coupling beam membrane shell 31 forms a coupling beam cavity 30 for pouring coupling beam concrete. The coupling beam reinforcement cage 32 is disposed within the coupling beam membrane shell 31, that is, within the coupling beam cavity 30. Specifically, a plurality of coupling beam vertical keels 34 are vertically fixedly disposed on both sides of the coupling beam reinforcement cage 32, and the bottoms of the coupling beam vertical keels 34 are fixedly connected (e.g., welded) to the upper surface of the coupling beam bottom steel plate 33. These vertical keels 34 not only provide vertical reinforcement for the coupling beam body 3, but also securely connect the coupling beam reinforcement cage 32 to the coupling beam membrane shell 31 via the vertical keels 34. The connecting beam vertical keel 34 can be angle steel, channel steel, flat steel plate, square steel bar or square steel pipe, etc. As shown in FIG24 , the connecting beam vertical keel 34 is a C-shaped channel steel; the connection between the connecting beam reinforcement cage 32 and the connecting beam vertical keel 34 can be fixedly connected by welding; optionally, the connecting beam body 3 also includes: a second connecting member (not shown in the figure); the connecting beam membrane shell 31 is fixedly connected to the connecting beam vertical keel 34 via the second connecting member. For example, the connection between the connecting beam vertical keel 34 and the connecting beam membrane shell 31 can be fixedly connected by an additional second connecting member. Optionally, the second connecting member can include self-tapping screws, bolts or rivets, etc.

[0149] Secondly, the length direction of the coupling beam reinforcement cage 32 and the length direction of the coupling beam bottom steel plate 33 are both the lateral extension direction of the coupling beam body 3. Both ends of the coupling beam reinforcement cage 32 and the ends of the coupling beam bottom steel plate 33 are connected to the shear wall bodies 1 at both ends of the coupling beam body 3, as shown in Figure 24 (Figure 24 only shows a schematic diagram of one end of the coupling beam body 3, and the other end is not shown for the same reason). Both ends of the coupling beam reinforcement cage 32 and the ends of the coupling beam bottom steel plate 33 are fixedly connected to the steel structure edge members 132 in the shear wall bodies 1 at both ends of the coupling beam body 3. Specifically, both ends of the coupling beam reinforcement cage 32 and the ends of the coupling beam bottom steel plate 33 can be fixedly connected to the surface of the steel structure edge member 132 by welding.

[0150] The prefabricated room module provided in the embodiment of the present invention can not only use the connecting beam membrane shell 31 and the connecting beam bottom steel plate 33 as beam templates during the module stage (including the stage before pouring concrete, such as the factory prefabrication stage, the hoisting and transportation stage, etc.), to facilitate the subsequent pouring of concrete on the connecting beam body 3 at the construction site, but also the connecting beam membrane shell 31 and the connecting beam bottom steel plate 33 can continue to participate in the force of the beam when the building structure is in use.

[0151] Optionally, as shown in Figure 1, the prefabricated room module may also include: a base plate 4, wherein the base plate 4 is a prefabricated part of the base plate combined with the building surface layer method, the edge of the base plate 4 is fixedly connected to the lower end of the shear wall body 1, and the base plate 4 is arranged opposite to the top plate body 2.

[0152] Since the embodiment of the present invention adopts modular means to prefabricate the prefabricated part of the module, namely the prefabricated room module, in advance in the factory, in order to further enhance the stability of the prefabricated room module during the hoisting and transportation process, the embodiment of the present invention strengthens the prefabricated room module by fixing the bottom plate 4 at the lower end of the shear wall body 1 of the prefabricated room module, so that when the prefabricated room module is subsequently hoisted and transported, the displacement, damage and disintegration of the components in the module due to braking or hoisting shaking will not occur.

[0153] Optionally, as shown in FIG. 25 , the base plate 4 includes: a steel frame 41 and / or base plate concrete 42 .

[0154] In the embodiment of the present invention, since the bottom plate 4 is a prefabricated part of the bottom plate combined with the building surface layer, the bottom plate 4 (the prefabricated part in the factory) can only include the steel frame 41 combined with the building surface layer. That is, the bottom plate 4 of the prefabricated room module processed in the factory only includes the steel frame 41. After the prefabricated room module is transported to the construction site, concrete is poured on the bottom plate 4, that is, the bottom plate concrete 42. Alternatively, the bottom plate 4 (the prefabricated part in the factory) can also only include the bottom plate concrete 42 combined with the building surface layer. That is to say, the bottom plate 4 of the prefabricated room module processed in the factory only includes the poured prefabricated bottom plate concrete 42, and does not include the steel frame 41; alternatively, the bottom plate 4 (the prefabricated part in the factory) can also include both the steel frame 41 combined with the building surface method and the bottom plate concrete 42 combined with the building surface method. In other words, the bottom plate 4 of the prefabricated room module processed in the factory includes both the steel frame 41 and the bottom plate concrete 42. After the prefabricated room module is transported to the construction site, there is no need to pour concrete on the bottom plate 4.

[0155] Optionally, referring to Figure 25, Figure 25 shows that the base plate 4 includes a steel frame 41, and the steel frame 41 includes: steel frame beams 411 and steel purlins 412. The steel frame beams 411 are fixedly connected to the lower ends of the shear wall body 1 by welding or bolting, forming a rectangular steel frame (such as a bottom frame). A plurality of steel purlins 412 are welded in the rectangular steel frame enclosed by the steel frame beams 411. The plurality of steel purlins 412 can be parallel to each other or can be arranged obliquely and crosswise, so that the steel frame beams 411 and the steel purlins 412 form a steel frame 41 with a planar structure.

[0156] An embodiment of the present invention further provides a modular building, as shown in FIG26 , which comprises: at least one prefabricated room module 500 as described above and concrete cast on-site within the prefabricated room module 500 and / or cast on-site between adjacent prefabricated room modules 500.

[0157] Because the embodiment of the present invention is a modular building system, the modular building ultimately constructed based on the prefabricated room modules 500 must include, in addition to the prefabricated room modules 500 prefabricated in advance at the factory, concrete poured into the wall cavities and pouring areas of the prefabricated room modules 500 to be poured with concrete at the construction site, as well as concrete poured at the joints between adjacent prefabricated room modules 500 when multiple prefabricated room modules 500 are spliced ​​together, resulting in a steel-concrete modular building. It should be noted that after the prefabricated room modules 500 are processed and prefabricated in the factory, they can be hoisted and transported to the construction site for concrete pouring.

[0158] The modular building provided by the embodiment of the present invention has a high quality guarantee because the prefabricated room modules 500 used are manufactured in a factory. The modular building is also more standardized and suitable for standardized building scenarios such as dormitories and hotels. In addition, because the modular building provided by the embodiment of the present invention is a steel-concrete composite structure, it can fully utilize the advantages of steel's high tensile strength and good plasticity and concrete's good compressive properties, compensating for their respective shortcomings. It not only has high load-bearing capacity and rigidity, but also has good seismic resistance, fire resistance, and corrosion resistance. Compared to steel modular buildings, the modular building provided by the embodiment of the present invention mainly uses the composite structure to bear the load, which can further reduce steel usage and save construction costs.

[0159] Optionally, as shown in Figure 27, the connection between any prefabricated room module 500 and the adjacent prefabricated room module 500 on the same floor is a local shear wall body, and the local shear wall body at the connection between two adjacent prefabricated room modules 500 forms a complete shear wall body 1 (as shown in Figure 28).

[0160] Among them, when two prefabricated room modules 500 are located on the same floor and are adjacent modules that need to be spliced ​​into one, that is, when the two prefabricated room modules 500 are spliced ​​horizontally, the wall at the connection point of each prefabricated room module 500 for splicing with another adjacent prefabricated room module 500 is a local shear wall body. In other words, the two horizontally adjacent prefabricated room modules 500 respectively include a part of the shear wall body. When the two prefabricated room modules 500 are spliced ​​together, the local shear wall body included in each prefabricated room module 500 at the connection point can be merged into a complete shear wall body, that is, the two horizontally adjacent prefabricated room modules 500 share one shear wall body.

[0161] Optionally, the local shear wall body of any one of the two adjacent prefabricated room modules 500 on the same floor includes a single-sided membrane shell, and the local shear wall body of the other prefabricated room module 500 includes a steel cage to be spliced ​​and another single-sided membrane shell fixedly connected to the steel cage to be spliced.

[0162] In the embodiment of the present invention, since the complete shear wall body includes a wall membrane shell fixedly installed on the surface of the edge member of the steel structure and a steel cage fixedly installed in the wall cavity formed by the wall membrane shell, the two horizontally adjacent prefabricated room modules 500 can be fixedly connected to the non-repeated and complementary partial components of the above-mentioned complete shear wall body, that is, the two horizontally adjacent prefabricated room modules 500 are fixedly connected to the complementary partial shear wall bodies, so that when the two prefabricated room modules 500 are horizontally spliced ​​together, the connection between the two can form a complete shear wall body.

[0163] Specifically, as shown in the left part of Figure 27, the surface of the steel structure edge member 132 at the connection of any one of the two horizontally adjacent prefabricated room modules 500 is fixedly connected to the single-sided membrane shell (the local shear wall body, such as the inner membrane shell, shown in Figure 27 with the reference mark M1); as shown in the right part of Figure 27, the surface of the steel structure edge member at the connection of the other prefabricated room module 500 is fixedly connected to the steel cage to be spliced ​​(shown in Figure 27 with the reference mark L) and the other single-sided membrane shell (the local shear wall body, such as the outer membrane shell, shown in Figure 27 with the reference mark M2). When the two prefabricated room modules 500 are horizontally adjacently spliced ​​together, as shown in Figure 28, the local shear wall bodies corresponding to the two modules are combined into a complete shear wall body 1, and the horizontal connection between the two prefabricated room modules 500 is achieved by pouring concrete into the complete shear wall body 1.

[0164] An embodiment of the present invention further provides another modular building, as shown in FIG26 , which includes: at least two prefabricated room modules 500 as described above, wherein each prefabricated room module 500 is connected to an adjacent prefabricated room module 500 located directly below or directly above it via a steel structure edge member 132 .

[0165] In particular, when two prefabricated room modules 500 are located on two adjacent floors above and below and are adjacent modules that need to be vertically spliced ​​to form a whole, that is, when the two prefabricated room modules 500 are spliced ​​up and down, each prefabricated room module 500 and another vertically adjacent prefabricated room module 500 can be fixedly connected by mutually aligned steel structure edge members 132 to form the two adjacent prefabricated room modules 500.

[0166] Alternatively, referring to FIG. 29 (it should be noted that FIG. 29 does not directly show the prefabricated room module 500, but only shows the steel structure edge members 132 of two upper and lower adjacent prefabricated room modules 500), the sheathing assembly 1323 of the steel structure edge member 132 of the prefabricated room module 500 is sheathed on the inner core column 1322 of the steel structure edge member 132 of the adjacent prefabricated room module 500 directly below it, and the sheathing assembly 1323 of the steel structure edge member 132 of the prefabricated room module 500 is sheathed on the inner core column 1322 of the steel structure edge member 132 of the adjacent prefabricated room module 500 directly below it. The top end of the steel column 1321 of the steel structure edge member 132 of the adjacent prefabricated room module 500 below is abutted, wherein the abutment here may also include: the situation where the two are not completely inserted into place due to low alignment accuracy, and there is a gap between the two. For example, there is a gap between the sleeve component 1323 of the steel structure edge member 132 of the prefabricated room module 500 and the top end of the steel column 1321 of the steel structure edge member 132 of the adjacent prefabricated room module 500 directly below it, and the gap is within the allowable range.

[0167] When two adjacent prefabricated room modules 500 are joined, the sleeve assembly 1323 of the steel structure edge member 132 of the upper prefabricated room module 500 is sleeved onto the inner core column 1322 of the steel structure edge member 132 of the lower prefabricated room module 500. Furthermore, the sleeve assembly 1323 of the steel structure edge member 132 of the upper prefabricated room module 500 is welded to the top of the steel column 1321 of the steel structure edge member 132 of the lower prefabricated room module 500, for example, by external welding. After welding, the anti-pullout structure protruding from the outer wall of the inner core column 1322 of the steel structure edge member 132 of the lower prefabricated room module 500 corresponds to the anti-pullout structure on the inner wall of the sleeve assembly 1323 of the steel structure edge member 132 of the upper prefabricated room module 500, which helps improve the anti-pullout performance after cement pouring. Optionally, as shown in FIG30 , vertical connecting steel bars 600 are provided inside the docking area of ​​the steel structure edge member 132 where two upper and lower adjacent prefabricated room modules 500 are connected, and after concrete is poured inside the docking area, the two upper and lower adjacent prefabricated room modules 500 are connected as one.

[0168] That is, in an embodiment of the present invention, two vertically adjacent prefabricated room modules 500 can be fixedly connected to form a whole by embedding vertical connecting steel bars 600 within the docking area of ​​the two modules and pouring concrete into the docking area where the vertical connecting steel bars 600 are embedded, thereby forming a whole. The docking area of ​​the two modules can be the connecting portion of the steel structure edge member 132 connecting the two vertically adjacent prefabricated room modules 500, as shown in the dotted line area in FIG30. The specific size of this area is determined by the length of the vertical connecting steel bars 600 inserted therein, and the length of the vertical connecting steel bars 600 is further determined based on the anchoring requirements. In addition, it should be noted that pouring concrete into the docking area where the vertical connecting steel bars 600 are embedded can be directly pouring concrete into the steel structure edge members 132 of the two vertically adjacent prefabricated room modules 500 (concrete is represented by the reference symbol T in FIG30), for example, by pouring concrete in sections downward from the upper end opening of the steel structure edge member 132 of the prefabricated room module 500 located on the upper layer. By adding the vertical connecting steel bars 600 , the connection strength between the upper and lower prefabricated room modules 500 can be further enhanced when concrete is poured inside the upper and lower connected steel structure edge members 132 .

[0169] An embodiment of the present invention further provides a construction method for a modular building. As shown in FIG31 , the construction method includes the following steps 101 .

[0170] Step 101: All prefabricated room modules are placed in place by hoisting. During and after the hoisting, the prefabricated room modules are gradually formed into a modular building by pouring concrete.

[0171] The prefabricated room modules transported to the construction site are placed at their corresponding preset positions using hoisting equipment. For example, the prefabricated room modules on the first floor are placed at the corresponding positions on the first floor, and the prefabricated room modules on the second floor are stacked on the upper layer of the prefabricated room modules on the first floor, etc. The embodiment of the present invention can not only perform the concrete pouring operation on the prefabricated room modules that have been placed in place after the hoisting is completed, but also directly pour concrete on the prefabricated room modules that have been placed in place during the hoisting process. For example, when a prefabricated room module is placed by hoisting, concrete can be poured into the prefabricated room module that has been placed in place, so that the shear wall body and the top plate body contained therein gradually form a shear wall and a top plate. In this process, the operation of hoisting the next prefabricated room module can also be carried out uninterruptedly and synchronously, so as to realize a synchronous construction process of hoisting and pouring, thereby greatly improving the construction speed.

[0172] In an embodiment of the present invention, prefabricated room modules processed in a factory are transported to a construction site by hoisting and placed in place. During the hoisting process, concrete is poured into the wall cavities, pouring areas, and other areas of the prefabricated room modules to be poured with concrete. When multiple prefabricated room modules are spliced ​​together, after the prefabricated room modules to be spliced ​​are hoisted, concrete is poured into the splicing locations between adjacent prefabricated room modules in place, thereby gradually forming a modular building. This construction method is based on the fact that the prefabricated room modules being hoisted and transported are lightweight, making hoisting and transportation more convenient. Furthermore, because this construction method is implemented specifically for prefabricated room modules, only the hoisting and concrete pouring of the prefabricated room modules at the construction site are required, eliminating all or most of the hoisting of small components, the erection of scaffolding and construction supports, and eliminating the need for on-site concrete formwork support, steel bar tying, and welding. This can significantly reduce the number of construction workers required at the construction site, while reducing the difficulty of on-site construction and improving construction speed and efficiency.

[0173] Optionally, the above-mentioned step 101 of "placing all prefabricated room modules in place by hoisting, and gradually forming a modular building from the prefabricated room modules in place by pouring in-situ concrete during and after the hoisting process" may include step A.

[0174] Step A: Construction of prefabricated room modules floor by floor from bottom to top to build a modular building.

[0175] Based on the basic construction process of multi-story buildings, prefabricated room modules are constructed layer by layer starting from the bottom until the modular building is completed.

[0176] The construction of the prefabricated room modules on each floor may include the following steps A1-A3.

[0177] Step A1: Use lifting equipment to place the prefabricated room modules to be constructed in place.

[0178] The prefabricated room modules that need to be constructed on this floor can be hoisted with hoisting equipment and placed in corresponding positions. The operation of hoisting the prefabricated room modules can be repeated until all the prefabricated room modules that need to be constructed on this floor have been placed in place.

[0179] Step A2: Concrete the complete shear wall body in the prefabricated room module placed in place to form the shear wall.

[0180] Once the prefabricated room modules on the floor have been hoisted and placed in place, concrete can be poured into the prefabricated room modules. Specifically, concrete can be poured into the complete shear wall bodies contained in the prefabricated room modules to form the shear walls. The present invention requires pouring concrete into the complete shear wall bodies because the complete shear wall bodies have a wall cavity between the inner and outer membrane shells for pouring concrete.

[0181] It should be noted that the process of pouring concrete in the embodiment of the present invention can be divided into multiple stages and poured step by step. For example, the complete shear wall body can be divided into three sections from bottom to top. First, concrete is poured into the wall cavity at the bottom, then concrete is poured into the wall cavity in the middle, and finally concrete is poured into the wall cavity at the top to complete the casting of the complete shear wall body, and no vibration is required during the entire pouring process.

[0182] Step A3: After the shear walls of all prefabricated room modules on the floor are formed by concrete pouring, concrete is poured into the top slabs of all prefabricated room modules on the floor to form the top slab of the floor.

[0183] In the embodiment of the present invention, when the shear wall bodies of all prefabricated room modules on a floor have been poured with concrete to form shear walls, the top plate bodies of all prefabricated room modules on the floor can be poured with concrete to obtain the top plate of the entire floor. After the top plate and shear walls of the floor are poured, the construction of all prefabricated room modules on the floor is completed; wherein, the top plate obtained after the casting can also provide support for the upper floors that need to be constructed later. In the embodiment of the present invention, after the shear walls are cast, the specific materials of the concrete can be replaced first, and then the top plate bodies of all prefabricated room modules on the floor can be cast with concrete to obtain the top plate, thereby further saving construction costs.

[0184] Optionally, the above step A2 of “pouring concrete on the complete shear wall body in the prefabricated room module placed in place to form the shear wall” may include the following steps A21-A22, or A23-A24.

[0185] Step A21: Each time a prefabricated room module is hoisted and placed, concrete is poured into the complete shear wall body of the prefabricated room module.

[0186] The embodiment of the present invention can start pouring concrete into the prefabricated room module when a prefabricated room module has been hoisted and placed in place on the floor. Specifically, concrete is poured into the complete shear wall body contained in the prefabricated room module that has been placed in place to form a shear wall. The reason why the embodiment of the present invention can pour concrete into the prefabricated room module that has been placed in place during the hoisting process is that the poured wall is a complete shear wall body, and the complete shear wall body in the embodiment of the present invention is a non-disassembly membrane shell structure having an inner membrane shell and an outer membrane shell, which has a wall cavity for pouring concrete. Even if other prefabricated room modules on the floor have not been hoisted and placed in place, pouring concrete into the complete shear wall body with the wall cavity will not cause concrete overflow due to the sealing of the inner membrane shell and the outer membrane shell. Therefore, when there is a prefabricated room module that has been placed in place on the floor, concrete can be poured into the complete shear wall body included in the prefabricated room module to form a shear wall.

[0187] Step A22: When the partial shear wall bodies at the connection between two horizontally adjacent prefabricated room modules are fixedly connected to form a complete shear wall body, concrete is poured into the complete shear wall body formed at the connection.

[0188] When at least two horizontally adjacent prefabricated room modules have been hoisted and placed in place on the floor, since the partial shear wall bodies of the two adjacent prefabricated room modules have been spliced ​​to form a complete shear wall body, concrete can be poured on the spliced ​​complete shear wall body to form a shear wall.

[0189] Alternatively, step A23: hoist and place all prefabricated room modules on the same floor; and fix and connect the local shear wall bodies at the connection points of horizontally adjacent prefabricated room modules to form a complete shear wall body.

[0190] Step A24: Pour concrete for all complete shear wall bodies within the floor.

[0191] Alternatively, all prefabricated room modules on the same floor can be hoisted and placed uniformly using hoisting equipment, that is, horizontally adjacent prefabricated room modules are all placed in place, and the local shear wall bodies at the connection points of the horizontally adjacent prefabricated room modules are first connected (such as welding the steel structure edge components at the connection points between two adjacent prefabricated room modules, etc.), so that the two adjacent local shear wall bodies can form a complete shear wall body, and then the concrete pouring operation is carried out on all the complete shear wall bodies on the floor.

[0192] The concrete pouring according to the above steps A21-A22 can increase the construction speed of the prefabricated room modules and greatly shorten the construction period.

[0193] Optionally, before the above step A2 of "pouring concrete on the complete shear wall body in the prefabricated room module placed in place to form the shear wall", the construction method may further include the following step B.

[0194] Step B: If the prefabricated room module to be constructed has other prefabricated room modules adjacent to it above and below, the connection points of the steel structure edge members of the adjacent prefabricated room modules above and below are fixedly connected.

[0195] Before pouring concrete for the complete shear wall body of the prefabricated room module in place, if there are other prefabricated room modules adjacent to it on the upper or lower level of the prefabricated room module, for example, the prefabricated room module is located on the 2nd floor, and another prefabricated room module located at the same position on the 1st floor is adjacent to it on the lower level of the prefabricated room module, then before pouring concrete for the complete shear wall body of the prefabricated room module on the 2nd floor, the connection of the steel structure edge members of the two adjacent prefabricated room modules can be vertically fixed first, for example, first fix the steel column module at the bottom of the steel structure edge member of the prefabricated room module on the 2nd floor to the steel structure of the prefabricated room module on the 1st floor and its adjacent prefabricated room module. The inner core column at the top of the edge member is plugged in, and the lower edge of the steel column module at the bottom of the steel structure edge member of the prefabricated room module on the second floor is abutted against the upper edge of the steel column in the steel structure edge member of the prefabricated room module on the first floor and its adjacent prefabricated room module, so that the anti-pullout structure with an anti-pullout effect on the inner side of the steel column module on the upper floor can cooperate with the convex ridge with an anti-pullout effect on the surface of the inner core column on the lower floor, further improving the anti-pullout performance between the steel structure edge members of the upper and lower prefabricated room modules after pouring concrete; thereafter, concrete is poured into the complete shear wall body of the upper and lower adjacent prefabricated room modules that have been fixed and connected, forming a shear wall with better anti-pullout effect.

Any technical solution that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
