Steel column modules, prefabricated steel column modules, prefabricated steel structures, prefabricated shear walls and modular buildings

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202310801217.1 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 application relates to the technical field of modular prefabricated buildings, and in particular to steel column modules, prefabricated steel column modules, prefabricated steel structures, prefabricated shear walls and modular buildings. Background Art

[0004] In existing technologies, modular prefabricated buildings consist of steel structures on both upper and lower floors, connected by plug-in connections. Typically, the connecting ends of the steel structures are designed to facilitate plug-in connections. After the connection is made, cement is poured into the steel structures, and once the cement solidifies, a stable and strong connection is achieved.

[0005] To enhance the pullout resistance between the ends of the upper and lower steel structures after cement pouring, pullout resistant components can be added to the ends of the steel structures. The current practice is to weld and deposit solder on the outside of the protruding core column at the top of the lower steel structure to form a strip-shaped protrusion, and to weld and deposit solder on the inner wall of the bottom end of the upper steel structure to form a strip-shaped protrusion.

[0006] However, due to the narrow internal space at the bottom of the upper steel structure, welding of tensile-resistant parts is extremely inconvenient and the stacking speed is slow, resulting in reduced production efficiency and hindering the realization of automated production.

[0063] A steel column module 100 is provided in an embodiment of the present application. Please refer to FIG1 , which is a schematic structural diagram of the steel column module 100 .

[0064] The steel column module 100 includes a steel column body 001 and a connecting assembly 010, which is mounted on the inner sidewall of the steel column body 001. The sidewall of the steel column body 001 is provided with multiple welding grooves 005. One side of the connecting assembly 010 has a concave-convex shape to form multiple anti-pullout structures extending along a predetermined direction 400. During installation, the side of the connecting assembly 010 facing away from the anti-pullout structure is attached to the inner sidewall of the steel column body 001. The connecting assembly 010 and the steel column body 001 are welded together at the welding grooves 005 from the outside of the steel column body 001.

[0065] When the upper and lower steel structures of a building are connected via the end-jointed structure and cement is poured into the steel structures, to enhance the pull-out resistance between the end-jointed portions of the upper and lower steel structures, the pull-out resistance structure provided on the connection assembly 010 extends in an angle with the axis of the steel column body 001. That is, when the steel column module 100 is in use, the pull-out resistance structure is not arranged vertically.

[0066] The steel column module 100 is constructed by attaching the connecting assembly 010 to the inner sidewall of the steel column body 001, with the side facing away from the anti-pullout structure. A welding groove 005 is provided on the steel column body 001. During welding, the connecting assembly 010 is welded to the steel column body 001 at the welding groove 005 on the outer sidewall of the steel column body 001. This forms a concave and convex anti-pullout structure on the inner sidewall of the steel column body 001, facilitating welding operations and greatly improving welding convenience, thereby increasing welding speed, improving production efficiency, and facilitating automated production.

[0067] The steel column module 100 provided in the embodiment of the present application is introduced in detail below.

[0068] Please refer to FIG. 2 , which is a schematic structural diagram of a first structure of the connection component 010 .

[0069] Specifically, the connection assembly 010 includes a steel plate 012 and a steel bar 014 , and the steel bar 014 is welded to the inner wall of the steel column body 001 through the steel plate 012 .

[0070] Optionally, there are multiple steel bars 014, and the steel plate 012 includes a first side surface and a second side surface facing each other. The multiple steel bars 014 are sequentially welded to the first side surface of the steel plate 012 at intervals. The multiple steel bars 014 extend along a predetermined direction 400 to form a pull-out resistant structure. The multiple steel bars 014 are welded to the steel plate 012 to form an integral structure. The second side surface of the steel plate 012 is then attached to the inner side wall of the steel column body 001. Finally, welding is performed from the outer side wall of the steel column body 001.

[0071] Alternatively, the steel plate 012 may be a thin-walled steel plate, the shape of which matches the inner wall shape of the steel column body 001, for example, a rectangular structure. A plurality of steel bars 014 are sequentially spaced apart, so that the first side surface of the steel plate 012 forms a concave-convex tensile-resistant structure.

[0072] Optionally, multiple steel bars 014 are evenly welded to the first side of the steel plate 012 , and each steel bar 014 extends along a preset direction 400 , and the multiple steel bars 014 are distributed in sequence along a direction perpendicular to the preset direction 400 .

[0073] Optionally, the shape of the steel bar 014 welded to the steel plate 012 is not limited and may be a wavy structure, an arcuate structure, a long straight structure, a long diagonal structure, a special-shaped structure, or a bent structure. When the steel bar 014 is 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. The present application does not limit the specific shape of the steel bar 014, as long as it is welded to the steel plate 012 and extends along the predetermined direction 400, forming a concave-convex structure on the first side surface of the steel plate 012 and providing a pull-out resistance effect.

[0074] Please refer to FIG. 3 , which is a schematic structural diagram of a second structure of the connection component 010 .

[0075] Specifically, connection assembly 010 includes a steel plate 012, which includes a first side surface and a second side surface facing each other. The first side surface is provided with a plurality of ridges 016 extending in a predetermined direction 400 to form a pull-out resistant structure. During installation, the second side surface of steel plate 012 is attached to the inner sidewall of steel column body 001 and welded.

[0076] Optionally, the ridge 016 and the steel plate 012 can be integrally formed, for example, by die casting, or extrusion molding, etc., which is not limited in the embodiments of the present application.

[0077] In other optional embodiments, a plurality of grooves may be sequentially and spaced apart from each other on the first side surface of the steel plate 012 , and the plurality of grooves extend along a preset direction 400 , with a ridge 016 formed between any two adjacent grooves.

[0078] Preferably, the width of the groove formed on the first side of the steel plate 012 can be much greater than the height, and can be formed by a milling process, that is, a plurality of grooves are milled on a flat plate by a milling process, so that any two adjacent grooves are separated by a ridge 016 .

[0079] Optionally, the shape of the ridge 016 on the first side surface of the steel plate 012 is not limited and may be a wavy structure, an arc structure, a long straight line structure, a long oblique line structure, a special-shaped structure, or a curved structure. When the ridge 016 is a curved 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. The present application does not limit the specific shape of the ridge 016, as long as it is protruding from the steel plate 012 and extends along the predetermined direction 400, forming a concave-convex structure on the first side surface of the steel plate 012 and providing a pull-out resistance effect.

[0080] In order to improve the connection stability between the connecting component 010 and the steel column body 001, in addition to welding and fixing through the position of the welding groove 005, the end of the steel plate 012 can also be welded and fixed to the end of the steel column body 001.

[0081] Furthermore, when the steel plate 012 is arranged on the inner side of the steel column body 001, the end of the steel plate 012 can be set flush with the end of the steel column body 001, or the end of the steel plate 012 can be slightly closer to the inside relative to the end of the steel column body 001, that is, slightly lower than the end of the steel column body 001.

[0082] Please refer to FIG. 4 , which is a schematic structural diagram showing the connection between the steel plate 012 and the end of the steel column body 001 .

[0083] Optionally, to facilitate welding, a weld seam 401 is provided at the connection between the steel plate 012 and the steel column body 001. Specifically, the end of the steel plate 012 adjacent to the inner wall of the steel column body 001 is chamfered, and / or the end of the steel column body 001 adjacent to the steel plate 012 is chamfered. Chamfering the ends of the steel plate 012 and the steel column body 001 at the joints forms a weld seam, facilitating welding and securing.

[0084] Please refer to FIG. 5 , which is a schematic structural diagram of a third structure of the connection component 010 .

[0085] Specifically, the connection assembly 010 is a frame structure, which may include a cross-beam 017 and a longitudinal beam 019. During installation, the longitudinal beam 019 is parallel to the axis of the steel column body 001, and the crossbeam 017 extends along a preset direction 400 to form a pull-out resistant structure.

[0086] Optionally, there can be at least two longitudinal beams 019 and multiple transverse beams 017. At least two longitudinal beams 019 extend axially along the steel column body 001, and multiple transverse beams 017 are spaced apart in sequence, with the ends of the transverse beams 017 connected to the outermost longitudinal beams 019. For example, in the structure shown in Figure 5, there are two longitudinal beams 019, each located at the outermost position, and multiple transverse beams 017 are evenly spaced between the two longitudinal beams 019.

[0087] During installation, the connection component 010 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 005 opened on the steel column body 001 needs to correspond to the solid beam of the frame structure. The solid beam can include horizontal beams and / or longitudinal beams to facilitate welding.

[0088] In summary, the welding groove 005 of the steel column body 001 must correspond to the physical structure of the connecting assembly 010. Optionally, the connecting assembly 010 includes a fitting portion that fits against the inner sidewall of the steel column body 001, and the opening position of the welding groove 005 is adapted to the fitting portion to facilitate welding from the outside of the steel column body 001.

[0089] Optionally, the welding groove 005 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 005. As long as it meets the production welding requirements, the steel column body 001 can be welded and fixed to the connecting component 010 through the welding groove 005 from the outer wall of the steel column body 001.

[0090] Optionally, the shape of the beam 017 can be a bent, wavy, arc-shaped or long straight-line structure. The present application does not limit the specific shape of the beam 017. As long as it extends as a whole along the preset direction 400, the connecting component 010 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-pull-out effect.

[0091] In this embodiment of the present application, to improve the pullout resistance between the ends of the upper and lower steel structures, a connection assembly 010 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 affixed with a connection assembly 010, thereby enhancing the pullout resistance from all sides.

[0092] The forming method and working principle of the steel column module 100 provided in the embodiment of the present application are as follows, and are explained using the connection assembly 010 shown in Figure 2 as an example.

[0093] Push multiple steel bars 014 evenly onto the steel plate 012 for positioning, and use a welding gun to spot weld each steel bar 014 to achieve preliminary fixation;

[0094] After fixing, remove the positioning mechanism and use a multi-head welding gun to simultaneously weld multiple steel bars 014 to fix the steel bars 014 and the steel plate 012 into one;

[0095] Repeat the above steps to form a plurality (e.g., four) of steel plates 012 welded with steel bars 014, i.e., connection components 010;

[0096] Place the connecting assembly 010 on one of the inner side walls of the steel column body 001, with the side of the connecting assembly 010 away from the steel bar 014 in contact with the inner side wall of the steel column body 001. Spot weld the ends of the connecting assembly 010 and the steel column body 001 to achieve preliminary fixation.

[0097] Repeat the above steps until each inner wall of the steel column body 001 is provided with a connection assembly 010;

[0098] Full welding is performed from the outer welding groove 005 position of the steel column body 001, and one side is flipped 90° during welding, and all sides are fully welded in turn.

[0099] In other optional embodiments, a connecting component may be first set on an inner side wall of the steel column body, and the connecting component may be welded and fixed to the steel column body at the welding groove position from the outside of the steel column body. After fixing, it may be flipped 90°, and then a connecting component may be set on the other inner side wall of the steel column body. Similarly, other connecting components may be fixed and welded to other inner side walls of the steel column body until all side welding is completed.

[0100] The process of "welding a pullout member on the inner sidewall of steel column body 001" is converted to: welding steel bar 014 to steel plate 012 with the aid of steel plate 012, creating welding groove 005 on the sidewall of steel column body 001, and welding steel plate 012 and steel column body 001 through welding groove 005, thereby indirectly welding steel bar 014 to the inner sidewall of steel column body 001 through steel plate 012. This facilitates operation and welding, increases welding speed, improves production efficiency, and facilitates further automated production.

[0101] A prefabricated steel column module 200 is further provided in an embodiment of the present application. Please refer to FIG6 , which is a schematic structural diagram of the prefabricated steel column module 200 .

[0102] Prefabricated steel column module 200 includes a steel column body 021, an inner core column 023, and the aforementioned steel column module 100. Steel column body 021 is a hollow, elongated structure with a bottom and a top. Steel column module 100 is fixedly connected to the bottom of steel column body 021, while inner core column 023 is fixedly connected to the top of steel column body 021, with inner core column 023 protruding from the top of steel column body 021.

[0103] Among them, the cross-sectional width dimension of the inner core column 023 is smaller than the cross-sectional width dimension of the steel column 021, and the cross-sectional width dimension of the steel column module 100 is the same as the cross-sectional width dimension of the steel column 021. The steel column module 100 can be fixedly connected to the bottom end of the steel column 021 by welding.

[0104] Optionally, in order to further improve the pull-out resistance between the end plug-in parts of the upper and lower steel structures, a pull-out resistance structure extending along a preset direction may be provided on the outer side wall of the inner core column 023 .

[0105] When the upper and lower layers of prefabricated steel column modules 200 are plugged in and cement is poured, the pull-out resistance of the steel structure can be effectively improved through the pull-out resistance structure of the outer wall of the inner core column 023 and the inner wall of the steel column module 100.

[0106] The prefabricated steel column module 200 has the beneficial effects of the above-mentioned steel column module 100, which will not be described in detail here.

[0107] An assembled steel structure 300 is also provided in an embodiment of the present application. Please refer to Figures 7 and 8. Figure 7 is a structural schematic diagram of the assembled steel structure 300, and Figure 8 is a cross-sectional view of the connection portion between the upper steel column module 031 and the lower steel column module 033.

[0108] The prefabricated steel structure 300 includes at least two of the above-mentioned prefabricated steel column modules, wherein the at least two prefabricated steel column modules include a lower steel column module 033 and an upper steel column module 031 .

[0109] After installation, the steel column module 100 of the upper steel column module 031 is sleeved on the inner core column 023 of the lower steel column module 033 , and the steel column module 100 of the upper steel column module 031 abuts against the top of the steel column body 021 of the lower steel column module 033 .

[0110] For example, the prefabricated steel structure 300 includes two prefabricated steel column modules 200, namely a lower steel column module 033 and an upper steel column module 031. The steel column modules 100 of the lower steel column module 033 are located at the bottom, and the inner core column 023 is located at the top. During installation, the steel column modules 100 of the upper steel column module 031 are placed over the inner core column 023 of the lower steel column module 033, and the steel column modules 100 of the upper steel column module 031 are mated and abutted against the steel column 021 of the lower steel column module 033.

[0111] After installation, the anti-pullout structure protruding from the outer wall of the inner core column 023 corresponds to the anti-pullout structure of the inner wall of the steel column module 100, which is beneficial to improving the anti-pullout performance after pouring cement.

[0112] The assembled steel structure 300 has the beneficial effects of the above-mentioned steel column module 100, which will not be described in detail here.

[0113] A prefabricated shear wall 500 is also provided in an embodiment of the present application. Please refer to FIG9 , which is a structural diagram of a first structure of the prefabricated shear wall 500 .

[0114] Specifically, the prefabricated shear wall 500 may include a shear wall body 510 and the above-mentioned prefabricated steel column module 200, the shear wall body 510 having a accommodating cavity; the number of prefabricated steel column modules 200 is two, the two prefabricated steel column modules 200 are fixedly connected to both sides of the shear wall body 510 along the length direction, and the shear wall body 510 and the two prefabricated steel column modules 200 enclose a wall cavity 515 for cast-in-place concrete.

[0115] The shear wall body 510 includes a receiving cavity. The shear wall body 510 and the two prefabricated steel column modules 200 at its ends enclose a wall cavity 515. This wall cavity 515 is used to accommodate concrete poured into the prefabricated shear wall 500 at the construction site, allowing the shear wall body 510 and prefabricated steel column modules 200 to form a shear wall. Once the concrete is poured into the wall cavity 515 and solidifies, the shear wall is formed.

[0116] As shown in Figure 9, two prefabricated steel column modules 200 are respectively fixedly connected to the longitudinal sides of the shear wall body 510 and are located in the receiving cavity of the shear wall body 510. The longitudinal sides of the shear wall body 510 mentioned above refer to the left and right sides of the shear wall body 510 when installed / in use. The geometric shape of the prefabricated shear wall 500 is defined by the shear wall body 510.

[0117] Furthermore, the shear wall body 510 may include an inner membrane shell 5102 and an outer membrane shell 5104 that are arranged relative to and in parallel. The inner membrane shell 5102, the outer membrane shell 5104 and the two prefabricated steel column modules 200 enclose a wall cavity 515. That is, the wall cavity 515 is formed by the inner membrane shell 5102, the outer membrane shell 5104 and the two prefabricated steel column modules 200 from four directions: front, back, left and right.

[0118] Continuing with FIG9 , in the embodiment of the present application, two prefabricated steel column modules 200 are fixedly connected to both sides of the shear wall body 510 along the length direction and are located in the accommodating cavity. The surface of the prefabricated steel column module 200 near the inner membrane shell 5102 is fixedly connected to the inner membrane shell 5102, and the surface of the prefabricated steel column module 200 near the outer membrane shell 5104 is fixedly connected to the outer membrane shell 5104. For example, the fixed connection method may include welding, bolt connection, or self-tapping screw connection. The embodiment of the present invention does not specifically limit the above-mentioned fixed connection method, and it can be determined according to actual needs.

[0119] Furthermore, the prefabricated shear wall 500 may also include a shear wall steel frame 530 .

[0120] Specifically, the shear wall steel frame 530 is fixedly connected in the wall cavity 515 , and the two ends of the shear wall steel frame 530 along the transverse direction are respectively fixedly connected to the two prefabricated steel column modules 200 .

[0121] Optionally, one side of the shear wall steel frame 530 along the thickness direction is fixedly connected to the inner membrane shell 5102 via a first connector, and the other side of the shear wall steel frame 530 along the thickness direction is fixedly connected to the outer membrane shell 5104 via a second connector. The shear wall steel frame 530 can be connected to the inner membrane shell 5102 and the outer membrane shell 5104 via the first connector and the second connector, respectively, so that the shear wall body 510 forms a "sandwich" structure. That is, one side of the shear wall steel frame 530 is connected to the inner membrane shell 5102 via the first connector, and the other side is connected to the outer membrane shell 5104 via the second connector, forming a monolithic structure with a non-removable formwork.

[0122] Optionally, the first connecting member and the second connecting member may include self-tapping screws, angle steels, channel steels or flat steel plates.

[0123] The length direction of the shear wall steel frame 530 is the lateral extension direction of the shear wall body 510. The prefabricated steel column modules 200 are vertically fixedly connected at both ends of the shear wall steel frame 530 extending along the length direction. The two ends of the shear wall steel frame 530 in the length direction can be fixedly connected to the surface of the prefabricated steel column modules 200 by welding.

[0124] Please refer to FIG10 , which is a schematic structural diagram of a second structure of a prefabricated shear wall 500 .

[0125] The prefabricated shear wall of this structure has the same basic structure as the prefabricated shear wall of the above-mentioned structure, with the difference that: the two prefabricated steel column modules 200 are fixedly connected to both sides of the shear wall body 510 along the length direction, but the prefabricated steel column module 200 is not located in the accommodating cavity of the shear wall body 510, that is, the prefabricated steel column module 200 is fixedly connected to the end of the shear wall body 510 along the length direction.

[0126] As shown in Figure 10, the shear wall body 510 includes an inner membrane shell 5102 and an outer membrane shell 5104. Two prefabricated steel column modules 200 are fixedly connected to the two ends of the shear wall body 510. Through the inner membrane shell 5102, the outer membrane shell 5104, and the two prefabricated steel column modules 200 on the left and right sides, a wall cavity 515 is enclosed from the front, back, left and right directions. The shear wall steel frame 530 is fixedly connected in the wall cavity 515, and the shear wall steel frame 530 is fixedly connected to the two prefabricated steel column modules 200 at both ends along the horizontal direction.

[0127] In summary, for the two prefabricated shear walls 500 of the above two structures, when the shear wall formed after the concrete is poured into the prefabricated shear wall 500 is the exterior wall of the building, the inner membrane shell 5102 of the shear wall body 510 is located on the side of the shear wall facing indoors, and the outer membrane shell 5104 of the shear wall body 510 is located on the side of the shear wall facing outdoors. The inner membrane shell 5102 and the outer membrane shell 5104 are arranged opposite and parallel to each other, and the wall cavity 515 is formed by the inner membrane shell 5102, the outer membrane shell 5104, and the prefabricated steel column modules 200 on both sides. In other words, at the construction site, the concrete poured into the prefabricated shear wall 500 will be poured between the inner membrane shell 5102, the outer membrane shell 5104, and the two prefabricated steel column modules 200 of the shear wall body 510.

[0128] Because the inner membrane shell 5102 and the outer membrane shell 5104 included in the shear wall body 510 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.

[0129] The present application also provides a modular building, including the above-mentioned steel column module, prefabricated steel column module or assembled steel structure. The modular building has the beneficial effects of the above-mentioned steel column module, which will not be described in detail here.
