[0078] A steel column connection structure 100 is provided in an embodiment of the present application. Please refer to FIG1 , which is a structural schematic diagram of the steel column connection structure 100 , and please refer to FIG2 , which is an exploded schematic diagram of the steel column connection structure 100 .

[0079] Specifically, the steel column connection structure 100 may include a first steel column 110 and a plug plate 115. The first steel column 110 is a hollow structure, and a first plug slot 112 is axially defined at the end of the first steel column 110. The plug plate 115 is inserted into the first plug slot 112, and at least one side of the plug plate 115 protrudes from the outer wall of the first steel column 110.

[0080] The steel column connection structure 100 provided in the embodiment of the present application can be used as a plug-in structure between the upper and lower steel column modules of a modular prefabricated building. The first steel column 110 can be fixedly connected to the top of the lower steel column module through the plug-in plate 115, which facilitates the bottom end of the upper steel column module to be sleeved on the steel column connection structure, thereby realizing the connection between the upper and lower steel column modules. By providing a first plug-in slot 112 on the first steel column 110, the plug-in plate 115 is inserted into the first plug-in slot 112, and at least one side of the plug-in plate 115 protrudes from the outer wall of the first steel column 110, it is convenient for the first steel column 110 to be fixedly connected to the top of the lower steel column module through the portion of the plug-in plate 115 protruding from the outer wall of the first steel column 110. The steel column connection structure 100 is easy to form, has a simple structure, is convenient for assembly and welding, can improve production efficiency while ensuring product quality, is conducive to automated production, and thus reduces labor production costs.

[0081] In order to improve the pull-out resistance after the ends of the upper and lower layers of steel column modules are connected and poured with cement, optionally, a structure for improving the pull-out resistance can be provided on the steel column connection structure 100 .

[0082] 1 , the steel column connection structure 100 may further include a steel bar 117 . The steel bar 117 is fixedly connected to the outer wall of the first steel column 110 , and the steel bar 117 extends along a preset direction 101 .

[0083] It should be noted that the preset direction 101 here refers to a direction that has an angle with the axial direction of the first steel column 110. When the steel column connection structure 100 is in use, the steel bar 117 extends roughly in the transverse direction, that is, the steel bar 117 is arranged in the transverse direction on the outer wall of the first steel column 110, and can also be arranged at an angle on the outer wall of the first steel column 110.

[0084] Furthermore, the number of steel bars 117 can be multiple, and the multiple steel bars 117 are spaced apart along the axial direction of the first steel column 110 on the outer wall of the first steel column 110, and the multiple steel bars 117 extend along the preset direction 101. The multiple steel bars 117 are spaced apart in sequence, so that the outer wall of the first steel column 110 forms a concave and convex tensile resistance structure.

[0085] Optionally, multiple steel bars 117 can be evenly welded to an outer wall of the first steel column 110, or evenly welded to each outer wall of the first steel column 110, and each steel bar 117 extends along a preset direction 101, and multiple steel bars 117 are distributed in sequence along the axial direction of the first steel column 110.

[0086] Optionally, the shape of the steel bars 117 welded to the outer wall of the first steel column 110 is not limited and may be a wavy structure, an arc structure, a long straight structure, a long oblique line structure, a special-shaped structure, or a bent structure. The present application does not limit the specific shape of the steel bars 117, as long as they are welded to the first steel column 110 and extend along the predetermined direction 101 as a whole, so that the outer wall of the first steel column 110 forms a concave-convex structure and has a pull-out resistance effect.

[0087] In this embodiment of the present application, to improve the pullout resistance between the ends of the upper and lower steel column modules, multiple steel bars 117 can be provided on each outer side wall of the first steel column 110. That is, the first steel column 110 includes multiple outer sides, each of which is provided with multiple steel bars 117, thereby enhancing the pullout resistance from all sides.

[0088] Optionally, the steel bar 117 with anti-pullout performance can be located at the end of the first steel column 110 away from the first plug-in slot 112, which is not only conducive to the plug-in fixation of the first steel column 110 and the plug-in plate 115, but also meets the anti-pullout performance of the steel column connection structure 100.

[0089] In other optional embodiments, the steel bars 117 may be distributed on the entire outer wall of the first steel column 110, that is, the end of the first steel column 110 where the first insertion slot 112 is provided may also be provided with the steel bars 117. This application does not limit this, and the specific configuration depends on actual needs.

[0090] In order to facilitate the smooth connection of the upper and lower steel column modules of the modular prefabricated building, when multiple steel column modules are assembled and connected up and down, in order to facilitate the smooth connection of the bottom end of the upper steel column module with the top end of the lower steel column module, a guide piece can be optionally provided on the top of the lower steel column module to guide the connection and facilitate smooth connection.

[0091] Specifically, the steel column connection structure 100 may further include a guide member, which is at least partially fixedly connected to the outer wall of the first steel column 110 , and is used to adapt to the bottom inner wall of another steel column module plugged into the steel column connection structure 100 .

[0092] The guide member is used to adapt to the bottom end of the upper steel column module to play a guiding role. Therefore, the guide member is located at the end of the first steel column 110 away from the first plug-in slot 112.

[0093] Please refer to FIG. 3 , which is a schematic structural diagram of a first structure of a guide member provided on the first steel column 110 .

[0094] The guide member may include a lug 121 fixedly connected to the outer sidewall of the first steel column 110 at a diagonal position. The number of lugs 121 may be at least two, two of which may be fixedly connected to the outer sidewall of the first steel column 110 at a diagonal position, respectively. The outermost lug 121 is used to cooperate with the inner sidewall of the upper steel column module, thereby achieving the purpose of guidance.

[0095] In order to further achieve the guiding effect, optionally, the side of the lug 121 away from the first steel column 110 can be designed as an arc structure.

[0096] By protruding a support ear 121 with an arc-shaped outer edge on the outer side wall of the first steel column 110 at a diagonal position, the upper steel column module and the lower steel column module can be smoothly connected.

[0097] Please refer to FIG. 4 , which is a schematic structural diagram of a second structure of a guide member provided on the first steel column 110 .

[0098] Specifically, the guide member may include a fixedly connected guide cone 123 and a guide column 125, wherein the guide column 125 is a slender rod-shaped structure, and the guide column 125 is fixedly connected to the outer wall of the diagonal position of the first steel column 110, and the guide cone 123 is connected to the end of the guide column 125 and is located at the end of the first steel column 110 away from the first plug-in slot 112.

[0099] Optionally, there may be multiple guide posts 125, each of which is fixed to the outer sidewalls of the first steel post 110 at diagonal positions (when the first steel post 110 is a quadrangular prism, there are four guide posts 125, and the four guide posts 125 are fixed to the outer sidewalls of the four corners of the quadrangular prism in a one-to-one correspondence). The guide cone 123 may include a conical piece connected to the guide posts 125 in a one-to-one correspondence, with the side of the conical piece away from the guide posts 125 intersecting at the middle position, so that the guide cone 123 can have a structure that is lower on the outside and higher in the middle.

[0100] It is understandable that the guide member may also include other structures, which are not specifically limited in this application and are determined based on actual needs.

[0101] In order to enable the steel column connection structure 100 to be installed in the middle position of the top of the lower steel column module, it is convenient for the upper and lower steel column modules to be plugged in and fixed, and it is also convenient for the upper and lower steel column modules to be adjusted in position after the initial socketing, so that the top of the first steel column of the lower steel column module is aligned and abutted with the bottom of the first steel column of the upper steel column module.

[0102] Optionally, referring to FIG. 1 , the first insertion slot 112 of the first steel column 110 is coplanar with the central axis of the first steel column 110 .

[0103] The plug-in plate 115 is a rectangular steel plate that is symmetrically inserted into the first steel column 110. That is, after the plug-in plate 115 is inserted into the first insertion slot 112 of the first steel column 110, both sides of the plug-in plate 115 protrude from the outer wall of the first steel column 110. The two sides of the plug-in plate 115 that protrude from the outer wall of the first steel column 110 are used to plug and fix with the steel columns in the lower steel column module.

[0104] The steel column connection structure 100 provided in the embodiment of the present application is designed to be installed at the connection between upper and lower steel column modules, facilitating the socketing of the upper steel column module with the lower steel column module. Furthermore, the steel column connection structure 100 facilitates secure installation with the lower steel column module, facilitating the molding process with ease and a simple structure, thereby improving production efficiency and enhancing the pull-out resistance of the upper and lower steel column modules after they are connected and poured with cement.

[0105] A steel column module 200 is further provided in an embodiment of the present application. Please refer to FIG5 , which is a schematic structural diagram of the steel column module 200 ; please refer to FIG6 , which is a schematic structural diagram of the second steel column 210 in the steel column module 200 .

[0106] Specifically, the steel column module 200 may include a second steel column 210 and the aforementioned steel column connection structure 100. The second steel column 210 is also hollow, with a second insertion slot 212 defined axially at one end. The insertion plate 115 of the steel column connection structure 100 is inserted into the second insertion slot 212 of the second steel column 210. After installation, the end of the first steel column 110 with the first insertion slot 112 is embedded in the cavity of the second steel column 210, and the first steel column 110 is fixedly connected to the second steel column 210 via the insertion plate 115.

[0107] The steel column module 200 provided in the embodiment of the present application fixedly connects the first steel column 110 and the second steel column 210 through the plug-in plate 115. When the plug-in plate 115 is plugged into the second plug-in slot 212 of the second steel column 210, the plug-in plate 115 and the second steel column 210 can be fixedly connected by welding.

[0108] The steel column module 200 has a simple structure and is easy to assemble and weld, sharing the advantages of the aforementioned steel column connection structure 100. During installation, the steel column module is positioned vertically, with the steel column connection structure 100 positioned at the top of the second steel column 210. The cross-sectional dimensions of the first steel column 110 are smaller than those of the second steel column 210, and the first steel column 110 protrudes from the top of the second steel column 210.

[0109] When the upper and lower steel column modules are connected through the ends, the upper steel column module is sleeved on the steel column connection structure 100 of the lower steel column module, making it convenient for the second steel column 210 of the upper steel column module to be sleeved on the steel column connection structure 100 of the lower steel column module.

[0110] For convenient connection, optionally, the first plug-in slot 112 of the first steel column 110 and the second plug-in slot 212 of the second steel column 210 are coplanar, so that the plug-in plate 115 can be inserted into the first plug-in slot 112 and the second plug-in slot 212 at the same time.

[0111] In order to further improve the connection stability between the steel column connection structure 100 and the second steel column 210, optionally, the middle position of the plug-in plate 115 cooperates with the first plug-in slot 112 of the first steel column 110, and the two side positions of the plug-in plate 115 cooperate with the second plug-in slot 212 of the second steel column 210.

[0112] In order to achieve smooth connection between the upper and lower layers of steel column modules, the relative positions of the connection ends of the second steel columns 210 of the upper and lower layers of steel column modules can also be adjusted according to actual needs.

[0113] Optionally, the steel column connection structure 100 can be set in the middle position of the second steel column 210, that is: the first plug-in groove 112 opened on the first steel column 110 is coplanar with the central axis of the first steel column 110, and the second plug-in groove 212 opened on the second steel column 210 is coplanar with the central axis of the second steel column 210.

[0114] It can be understood that, under the premise that the first plug-in slot 112 opened in the first steel column 110 is coplanar with the central axis of the first steel column 110, the first plug-in slot 112 can be perpendicular to the side wall of the first steel column 110; it can also be tilted and have an angle with the side wall of the first steel column 110; or, the first plug-in slot 112 can be opened at a diagonal position of the first steel column 110.

[0115] Similarly, on the premise that the second plug-in slot 212 opened on the second steel column 210 is coplanar with the central axis of the second steel column 210, the second plug-in slot 212 can also be perpendicular to the side wall of the second steel column 210; it can also be set at an angle to have an angle with the side wall of the second steel column 210; or, the second plug-in slot 212 can be opened at a diagonal position of the second steel column 210.

[0116] The steel column module 200 provided in the embodiment of the present application has the beneficial effects of the above-mentioned steel column connection structure 100, which will not be described in detail here.

[0117] The embodiment of the present application further provides a steel column forming device 300 , which is used to prepare the above-mentioned steel column connection structure 100 or steel column module 200 .

[0118] Please refer to FIG. 7 , which is a schematic structural diagram of a steel column forming device 300 .

[0119] Specifically, the steel column forming equipment 300 may include a frame 310, a clamping chuck mechanism 320, and a pushing mechanism 330. The frame 310 is fixedly mounted on a workbench or the ground, the clamping chuck mechanism 320 is rotatably mounted on the frame 310, and the pushing mechanism 330 is mounted on the frame 310.

[0120] When the steel column forming equipment 300 is used to prepare the steel column connection structure 100, the clamping chuck mechanism 320 is used to clamp one end of the first steel column 110 away from the first plug-in slot 112, and the pushing mechanism 330 is used to clamp the plug-in plate 115 and drive the plug-in plate 115 to move axially along the first steel column 110 so that the plug-in plate 115 is inserted into the first plug-in slot 112 of the first steel column 110.

[0121] Similarly, when the steel column forming equipment 300 is used to prepare the steel column module 200, the clamping chuck mechanism 320 is used to clamp the second steel column, and make the end of the second steel column with the second plug-in groove protrude, and the pushing mechanism 330 is used to clamp the steel column connecting structure, and make the end of the steel column connecting structure with the plug-in plate close to the end of the second steel column with the second plug-in groove, and the pushing mechanism 330 drives the steel column connecting structure to move axially along the second steel column so that the plug-in plate is inserted into the second plug-in groove of the second steel column.

[0122] It is understood that, in other optional embodiments, the clamping chuck mechanism in the steel column forming apparatus may also clamp the plug-in plate, the pushing mechanism clamps the end of the first steel column away from the first plug-in slot, and drives the first steel column to move axially to securely plug the first steel column to the plug-in plate. Alternatively, the clamping chuck mechanism in the steel column forming apparatus may also clamp the end of the steel column connecting structure away from the plug-in plate, the pushing mechanism clamps the second steel column, and brings the end of the second steel column having the second plug-in slot closer to one end of the plug-in plate, and the pushing mechanism drives the second steel column to move axially to securely plug the second steel column to the plug-in plate of the steel column connecting structure.

[0123] The present application does not limit the specific scheme for preparing the steel column connection structure 100 or the steel column module 200 using the steel column forming equipment 300, and it is determined based on actual needs and convenience.

[0124] The steel column forming equipment 300 provided in the embodiment of the present application has a reasonable structural design. One of the assembly parts is clamped by the clamping chuck mechanism 320, and the other assembly part is clamped and driven to move along the preset assembly direction by the pushing mechanism 330 until the two assembly parts are connected. The pushing operation is convenient, which can improve the assembly efficiency while ensuring the assembly quality, and is also conducive to the realization of fully automated production.

[0125] The following takes the preparation of the steel column connection structure 100 by the steel column forming equipment 300 provided in the embodiment of the present application as an example, and the specific structure of the steel column forming equipment 300 is introduced in detail.

[0126] Please refer to FIG. 8 , which is a schematic structural diagram of the pushing mechanism 330 from a first perspective.

[0127] Specifically, the pushing mechanism 330 may include a first driving cylinder 3301 , a first base plate 3303 , a second base plate 3305 and a third base plate 3307 that are fixedly connected.

[0128] The first drive cylinder 3301 and the first base plate 3303 are respectively fixedly connected to the frame 310. The first base plate 3303 may be a U-shaped structure including two opposing side walls. A first roller 3311 is rotatably mounted on each side wall of the first base plate 3303. The central axis of the first roller 3311 is horizontally arranged, allowing the first roller 3311 to rotate vertically. The second base plate 3305 and the third base plate 3307 may be respectively fixed to the side walls of the first base plate 3303. A second roller 3313 is rotatably mounted on the second base plate 3305. The central axis of the second roller 3313 is vertically arranged, allowing the second roller 3313 to rotate horizontally. The third roller 3315 is rotatably mounted on the third base plate 3307. The central axis of the third roller 3315 is vertically arranged, allowing the third roller 3315 to rotate horizontally.

[0129] When the plug board 115 is mounted on the pushing mechanism 330 , the first roller 3311 of the pushing mechanism 330 is adapted to fit the bottom wall of the plug board 115 , and the second roller 3313 and the third roller 3315 are adapted to fit the side walls of the plug board 115 .

[0130] The first roller 3311 on the first base plate 3303, the second roller 3313 on the second base plate 3305, and the third roller 3315 on the third base plate 3307 cooperate to clamp the plug board 115. The first roller 3311 rolls against the bottom wall of the plug board 115, while the second roller 3313 and the third roller 3315 roll against the side walls of the plug board 115. The first driving cylinder 3301 pushes the plug board 115. Under the force of the first driving cylinder 3301 and the rolling cooperation of the first roller 3311, the second roller 3313, and the third roller 3315, the plug board 115 moves toward the end of the first steel column having the first insertion slot, so that the plug board 115 is inserted into the first insertion slot of the first steel column.

[0131] In order to adapt to connectors of different sizes, optionally, the third roller 3315 on the third substrate 3307 can be set to an adjustable structure.

[0132] Specifically, please refer to FIG. 9 , which is a schematic structural diagram of the pushing mechanism 330 from a second perspective.

[0133] The pushing mechanism 330 may further include a second driving cylinder 3321 , which is fixedly connected to the third base plate 3307 , and the third roller 3315 is rotatably disposed on the driving end of the second driving cylinder 3321 .

[0134] In order to set multiple third rollers 3315 on the driving end of the second driving cylinder 3321, the driving end of the second driving cylinder 3321 can also be fixedly connected to the mounting plate 3323. There are multiple third rollers 3315, and the multiple third rollers 3315 are rotatably mounted on the mounting plate 3323.

[0135] Optionally, there may be multiple first rollers 3311, multiple second rollers 3313, and multiple third rollers 3315, each of which is arranged in sequence. Rolling friction is created between the rollers and the plug board 115, which reduces frictional resistance when the plug board 115 moves along the axial direction of the first steel column under the drive of the first drive cylinder 3301, thereby facilitating the sliding of the plug board 115 under the drive of the first drive cylinder 3301.

[0136] Furthermore, in order to position the plug board 115 from the top, the plug board 115 is prevented from falling out from the top during the movement. Alternatively, please refer to FIG10 , which is a schematic structural diagram of the pushing mechanism 330 from a third perspective.

[0137] Specifically, the pushing mechanism 330 may further include a third driving cylinder 3325 , a connecting rod 3327 and a fourth roller 3329 .

[0138] The third driving cylinder 3325 is fixedly connected to the frame 310. The first end of the connecting rod 3327 is hinged to the driving end of the third driving cylinder 3325. The middle position of the connecting rod 3327 is hinged to the frame 310. The second end of the connecting rod 3327 is rotatably provided with a fourth roller 3329. The third driving cylinder 3325 drives the fourth roller 3329 to abut against or away from the top wall of the plug board 115 via the connecting rod 3327.

[0139] For example: when the third driving cylinder 3325 is extended, the first end of the connecting rod 3327 connected to the third driving cylinder 3325 rotates upward (counterclockwise from the perspective of Figure 10), and the second end provided with the fourth roller 3329 rotates downward (counterclockwise from the perspective of Figure 10), while driving the fourth roller 3329 to press against the top wall of the plug board 115, thereby limiting the position of the plug board 115 from the top.

[0140] When the third driving cylinder 3325 contracts, the first end of the connecting rod 3327 connected to the third driving cylinder 3325 rotates downward (clockwise from the perspective of Figure 10), and the second end provided with the fourth roller 3329 rotates upward (clockwise from the perspective of Figure 10), and at the same time drives the fourth roller 3329 away from the top wall of the plug board 115, thereby releasing the restriction on the plug board 115 from the top.

[0141] The pushing mechanism 330 fixed on the frame 310 pushes the plug-in plate 115 along the axial direction of the first steel column 110, and limits the plug-in plate 115 from the bottom wall, side wall and top wall respectively through the first roller 3311, the second roller 3313, the third roller 3315 and the fourth roller 3329, thereby ensuring that the plug-in plate 115 will not deflect during the axial movement along the first steel column 110, thereby ensuring smooth plug-in and correct plug-in position, which is conducive to improving the assembly quality in the subsequent assembly process.

[0142] Please refer to FIG. 11 , which is a schematic structural diagram of the clamping chuck mechanism 320 .

[0143] Specifically, the clamping chuck mechanism 320 may include a driving mechanism 321 , a rotating disk 323 , a first resisting assembly 325 , and a second resisting assembly 327 .

[0144] The drive mechanism 321 is mounted on the frame 310 and is in transmission connection with the turntable 323, driving the turntable 323 to rotate. To facilitate clamping the first steel column, a central through-hole 3230 is provided in the middle of the turntable 323 for receiving the first steel column. A first push assembly 325 and a second push assembly 327 are disposed on the side of the turntable 323 facing away from the drive mechanism 321. The first push assembly 325 is used to limit the first steel column in the first direction 103, while the second push assembly 327 is used to limit the first steel column in the second direction 105.

[0145] In the viewing angle shown in FIG. 11 , optionally, the first direction 103 refers to a horizontal direction, and the second direction 105 refers to a vertical direction.

[0146] Optionally, the driving mechanism 321 and the turntable 323 can be connected by gear transmission, that is, the driving mechanism 321 may include a motor and a first gear, the motor is fixedly connected to the mounting frame of the frame 310, and the motor is located on the side of the mounting frame away from the pushing mechanism 330, the power output end of the motor is connected to the first gear transmission, the first gear and the motor are respectively located on both sides of the mounting frame, the outer peripheral wall of the turntable 323 is provided with a plurality of teeth meshing with the first gear, and the motor drives the turntable 323 with multiple teeth to rotate through the first gear.

[0147] In other optional embodiments, the driving mechanism 321 may also include a second gear, the turntable 323 is a plate-shaped structure, the turntable 323 is fixedly connected to the second gear, the first gear is externally meshed with the second gear, the motor drives the first gear to rotate, and the first gear drives the turntable 323 to rotate through the second gear.

[0148] The present application does not limit the specific structure of the driving mechanism 321 , which is determined according to actual needs, as long as the driving mechanism 321 can drive the turntable 323 to rotate.

[0149] Furthermore, the first push assembly 325 and the second push assembly 327 cooperate to limit the first steel column from four directions of the first steel column cross section. Since the first push assembly 325 pushes the first steel column along the first direction 103, the second push assembly 327 pushes the first steel column along the second direction 105.

[0150] In order to avoid interference between the first and second abutting components 325, 327 during the abutting process, the first and second abutting components 325, 327 are optionally offset in a direction perpendicular to the turntable 323. That is, the abutting path of the first and second abutting components 325 and 327 are not located in the same plane.

[0151] Optionally, the structures of the first push component 325 and the second push component 327 can be the same or different, depending on actual needs. In the embodiment of the present application, the structures of the first push component 325 and the second push component 327 are the same.

[0152] Please refer to FIG12 , which is a schematic diagram of the structure of the push assembly.

[0153] The first and second push assemblies 325 and 327 may each include a contact plate 3251, a contact plate 3253, and a fourth drive cylinder 3255. The fourth drive cylinder 3255 is fixedly connected to the turntable 323. The contact plate 3253 is fixedly connected to the drive end of the fourth drive cylinder 3255 and is configured to engage with the sidewalls of the first steel column. The contact plate 3251 is fixedly connected to the turntable 323, and the contact plate 3251 and the fourth drive cylinder 3255 are respectively located on either side of the central through hole 3230 of the turntable 323. Under the action of the fourth drive cylinder 3255, the contact plate 3253 pushes against the first steel column, while the contact plate 3251 is configured to resist the first steel column, thereby positioning the first steel column.

[0154] In other optional embodiments, the clamping chuck mechanism 320 may also have other structures. For example, the clamping chuck mechanism may be a hollow cylindrical structure that is rotatable relative to the frame. A clamping mechanism is disposed in the cavity of the clamping chuck mechanism. The first steel column is embedded in the cavity of the clamping chuck mechanism and is clamped and fixed by the clamping mechanism. The clamping chuck mechanism can drive the first steel column to rotate relative to the frame to adjust the angle of the first steel column.

[0155] The present application does not limit the specific structure of the clamping chuck mechanism, as long as the clamping chuck mechanism can clamp and fix the first steel column and drive the first steel column to rotate.

[0156] The steel column forming apparatus 300 provided in the embodiment of the present application is rationally designed. A clamping chuck mechanism 320 clamps and secures the first steel column 110. A pushing mechanism 330 clamps the plug-in plate 115 and drives it toward the first steel column 110 until it is inserted into the first insertion slot 112 of the first steel column 110. This steel column forming apparatus offers convenient clamping and pushing operations, enabling accurate and convenient insertion, facilitating subsequent welding operations, improving assembly speed and efficiency while ensuring assembly quality, and facilitating fully automated production.

[0157] An assembled steel structure 400 is also provided in an embodiment of the present application. Please refer to Figures 13 and 14. Figure 13 is a structural schematic diagram of the assembled steel structure 400, and Figure 14 is a cross-sectional view of the connection portion between the upper steel column module 420 and the lower steel column module 410.

[0158] The prefabricated steel structure 400 may include at least two of the above-mentioned steel column modules, wherein the at least two steel column modules may include a lower steel column module 410 and an upper steel column module 420 .

[0159] After installation, the second steel column 210 of the upper steel column module 420 is sleeved on the first steel column 110 of the lower steel column module 410 , and the top of the second steel column 210 of the upper steel column module 420 abuts against the top of the second steel column 210 of the lower steel column module 410 .

[0160] For example, referring to Figure 14 , a prefabricated steel structure 400 includes two steel column modules: a lower steel column module 410 and an upper steel column module 420. The first steel column 110 of the lower steel column module 410 is positioned atop the second steel column 210. During installation, the second steel column 210 of the upper steel column module 420 is sleeved onto the first steel column 110 of the lower steel column module 410, with the second steel column 210 of the upper steel column module 420 matingly abutting the second steel column 210 of the lower steel column module 410.

[0161] After installation, the steel bars 117 protruding from the outer wall of the first steel column 110 face the inner wall of the second steel column 210 , which is beneficial to improving the tensile strength after pouring cement.

[0162] The assembled steel structure 400 has the beneficial effects of the above-mentioned steel column module 200, which will not be described in detail here.

[0163] A prefabricated shear wall 500 is also provided in an embodiment of the present application. Please refer to FIG15 , which is a structural schematic diagram of a first structure of the prefabricated shear wall 500 .

[0164] Specifically, the prefabricated shear wall 500 may include a shear wall body 510 and the above-mentioned steel column module 200, the shear wall body 510 having a accommodating cavity; the number of steel column modules 200 is two, the two 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 steel column modules 200 enclose a wall cavity 515 for cast-in-place concrete.

[0165] The shear wall body 510 includes a receiving cavity. The shear wall body 510 and the two 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 the 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.

[0166] As shown in Figure 15 , two steel column modules 200 are 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.

[0167] 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 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 steel column modules 200 from four directions of front, back, left and right.

[0168] Continuing with FIG. 15 , in the embodiment of the present application, two 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 steel column module 200 near the inner membrane shell 5102 is fixedly connected to the inner membrane shell 5102, and the surface of the 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, bolting, or self-tapping screw connection. The embodiment of the present invention does not specifically limit the above-mentioned fixed connection method, and the specific method is determined according to actual needs.

[0169] Furthermore, the prefabricated shear wall 500 may also include a shear wall steel frame 530 .

[0170] 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 steel column modules 200 .

[0171] 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.

[0172] Optionally, the first connecting member and the second connecting member may include self-tapping screws, angle steels, channel steels or flat steel plates.

[0173] The length direction of the shear wall steel frame 530 is the lateral extension direction of the shear wall body 510. The steel column modules 200 are vertically fixedly connected at both ends of the shear wall steel frame 530 extending in 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 steel column modules 200 by welding.

[0174] Please refer to FIG16 , which is a schematic structural diagram of a second structure of a prefabricated shear wall 500 .

[0175] 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 steel column modules 200 are fixedly connected to both sides of the shear wall body 510 along the length direction, but the steel column module 200 is not located in the accommodating cavity of the shear wall body 510, that is, the steel column module 200 is fixedly connected to the end of the shear wall body 510 along the length direction.

[0176] As shown in Figure 16, the shear wall body 510 includes an inner membrane shell 5102 and an outer membrane shell 5104. Two 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 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 steel column modules 200 at both ends along the horizontal direction.

[0177] 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 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 steel column modules 200 of the shear wall body 510.

[0178] 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.

[0179] A modular building is also provided in an embodiment of the present application, including the above-mentioned steel column connection structure, steel column module or assembled steel structure.

[0180] This modular building has the beneficial effects of the above-mentioned steel column module, which will not be described in detail here.
