Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0075] This application provides a steel column connection structure 100. Please refer to... Figure 1 The diagram shown is a structural schematic of the steel column connection structure 100. Please refer to it. Figure 2 The diagram shown is an exploded view of the steel column connection structure 100.

[0076] Specifically, the steel column connection structure 100 may include a first steel column 110 and a plug-in plate 115. The first steel column 110 is a hollow structure, and a first plug-in groove 112 is formed at the end of the first steel column 110 along the axial direction. The plug-in plate 115 is inserted into the first plug-in groove 112, and at least one side of the plug-in plate 115 protrudes from the outer side wall of the first steel column 110.

[0077] The steel column connection structure 100 provided in this embodiment can serve as an interlocking structure between upper and lower steel column modules in a modular prefabricated building. The first steel column 110 can be fixedly connected to the top of the lower steel column module via an interlocking plate 115, facilitating the bottom end of the upper steel column module to be fitted onto this steel column connection structure, thus connecting the upper and lower steel column modules. A first interlocking groove 112 is opened on the first steel column 110, and the interlocking plate 115 is inserted into the first interlocking groove 112. At least one side of the interlocking plate 115 protrudes from the outer wall of the first steel column 110, facilitating the fixed connection between the first steel column 110 and the top of the lower steel column module via the portion of the interlocking plate 115 protruding from the outer wall of the first steel column 110. This steel column connection structure 100 is easy to form, has a simple structure, and is convenient for assembly and welding. While ensuring product quality, it can improve production efficiency, facilitate automated production, and thus reduce labor production costs.

[0078] To improve the pull-out resistance of the upper and lower steel column modules after the end connection is made and cement is poured, optionally, a structure for improving pull-out resistance can be provided on the steel column connection structure 100.

[0079] Please continue to refer to Figure 1 The steel column connection structure 100 may also include a reinforcing bar 117, which is fixedly connected to the outer wall of the first steel column 110 and extends along a predetermined direction 101.

[0080] It should be noted that the preset direction 101 here refers to the direction that is at an angle to the axis of the first steel column 110. When the steel column connection structure 100 is in use, the reinforcing bar 117 extends roughly in the transverse direction, that is, the reinforcing bar 117 is set in the transverse direction on the outer side wall of the first steel column 110, or it can be set at an angle on the outer side wall of the first steel column 110.

[0081] Furthermore, there can be multiple reinforcing bars 117, which are spaced apart along the axial direction of the first steel column 110 on the outer side wall of the first steel column 110, and all of the multiple reinforcing bars 117 extend along a predetermined direction 101. The multiple reinforcing bars 117 are distributed sequentially at intervals, so that the outer side wall of the first steel column 110 forms a concave-convex tensile-resistant structure.

[0082] Optionally, multiple reinforcing bars 117 can be uniformly welded to one outer wall of the first steel column 110, or uniformly welded to each outer wall of the first steel column 110, and each reinforcing bar 117 extends along a preset direction 101, and multiple reinforcing bars 117 are distributed sequentially along the axial direction of the first steel column 110.

[0083] Optionally, the shape of the reinforcing bar 117 welded to the outer wall of the first steel column 110 is not limited. It can be a wavy structure, an arc-shaped structure, a long straight structure, a long oblique line structure, an irregular structure, or a bent structure. This application does not limit the specific shape of the reinforcing bar 117, as long as it is welded to the first steel column 110 and extends along the predetermined direction 101, so that the outer wall of the first steel column 110 forms a concave-convex structure with a pull-out resistance effect.

[0084] In this embodiment, to improve the pull-out resistance between the end joints of the upper and lower steel column modules, multiple reinforcing 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 side walls, and each outer side wall is provided with multiple reinforcing bars 117 to enhance the pull-out resistance from various sides.

[0085] Optionally, the steel bar 117 with pull-out resistance can be located at the end of the first steel column 110 away from the first insertion slot 112, which not only facilitates the insertion and fixing of the first steel column 110 and the insertion plate 115, but also satisfies the pull-out resistance of the steel column connection structure 100.

[0086] In alternative embodiments, the reinforcing bars 117 may be distributed on all the outer walls of the first steel column 110, that is, the reinforcing bars 117 may also be provided at the end of the first steel column 110 where the first insertion slot 112 is opened. This application does not limit this, and it depends on the actual needs.

[0087] To facilitate the smooth connection of upper and lower steel column modules in modular prefabricated buildings, when assembling multiple steel column modules by overlapping, a guide component can be optionally installed on the top of the lower steel column module to guide the connection and ensure a smooth fit.

[0088] Specifically, the steel column connection structure 100 may also include a guide member, which is at least partially fixed to the outer side wall of the first steel column 110. The guide member is used to adapt to the bottom inner wall of another steel column module that is inserted into the steel column connection structure 100.

[0089] The guide is used to fit with the bottom end of the upper steel column module to play a guiding role. Therefore, the guide is located at the end of the first steel column 110 away from the first insertion slot 112.

[0090] Please refer to Figure 3 The diagram shows a schematic of the first type of structure with guide members installed on the first steel column 110.

[0091] The guide component may include lugs 121, which are fixedly connected to the outer side wall of the first steel column 110 at a diagonal position. There may be at least two lugs 121, with two of them fixedly connected to the outer side wall of the first steel column 110 at a diagonal position. The outermost lug of the lug 121 is used to mate with the inner side wall of the upper steel column module, thus achieving the purpose of guidance.

[0092] To further enhance the guiding function, the side of the lug 121 furthest from the first steel column 110 may optionally be designed as an arc-shaped structure.

[0093] By providing lugs 121 with arc-shaped outer edges protruding from the outer side wall at the diagonal position of the first steel column 110, it is convenient for the upper steel column module to be smoothly connected to the lower steel column module.

[0094] Please refer to Figure 4 The diagram shows a schematic of the second type of structure with guide members installed on the first steel column 110.

[0095] Specifically, the guide may include a guide cone 123 and a guide post 125 that are fixedly connected. The guide post 125 is a slender rod-shaped structure. The guide post 125 is fixedly connected to the outer wall of the first steel column 110 at the diagonal position. The guide cone 123 is connected to the end of the guide post 125 and is located at the end of the first steel column 110 away from the first insertion groove 112.

[0096] Optionally, there can be multiple guide posts 125, each fixed to the outer wall of the first steel column 110 at a diagonal position (when the first steel column 110 is a quadrangular prism, there are four guide posts 125, each fixedly connected to the outer wall of the four corners of the quadrangular prism). The guide cone 123 may include conical plates connected to the guide posts 125 in a corresponding manner. The sides of the conical plates away from the guide posts 125 intersect at the middle position, so that the guide cone 123 can have a structure that is low on the outside and high in the middle.

[0097] It is understood that the guide component may also include other structures, which are not specifically limited in this application and are determined according to actual needs.

[0098] In order to ensure that the steel column connection structure 100 is installed in the middle position of the top of the lower steel column module, it is convenient to insert and fix the upper and lower steel column modules, and also convenient to adjust the position of the upper and lower steel column modules after the initial fitting, so that the top of the first steel column of the lower steel column module is aligned and abuts against the bottom of the first steel column of the upper steel column module.

[0099] Alternatively, please continue to refer to Figure 1 As shown, the first insertion slot 112 of the first steel column 110 is coplanar with the central axis of the first steel column 110.

[0100] The insertion plate 115 is a rectangular steel plate, which is symmetrically inserted into the first steel column 110. That is, after the insertion plate 115 is inserted into the first insertion slot 112 of the first steel column 110, both sides of the insertion plate 115 protrude from the outer wall of the first steel column 110. The two sides of the insertion plate 115 protruding from the outer wall of the first steel column 110 are used for insertion and fixation with the steel columns in the lower steel column module.

[0101] The steel column connection structure 100 provided in this embodiment is used for installation at the connection position between upper and lower steel column modules, facilitating the connection between the upper and lower steel column modules. Furthermore, the steel column connection structure 100 is easy to fix and install with the lower steel column module, the molding process is convenient, the structure is simple, it can improve production efficiency, and it also helps to improve the tensile strength of the upper and lower steel column modules after connection and cement pouring.

[0102] This application embodiment also provides a steel column module 200, please refer to... Figure 5 The diagram shown is a structural schematic of the steel column module 200; please refer to... Figure 6The diagram shows the structure of the second steel column 210 in the steel column module 200.

[0103] Specifically, the steel column module 200 may include a second steel column 210 and the aforementioned steel column connecting structure 100. The second steel column 210 is also a hollow structure, with a second insertion slot 212 axially formed at one end. The insertion plate 115 of the steel column connecting 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.

[0104] The steel column module 200 provided in this application embodiment fixes the first steel column 110 and the second steel column 210 together by means of a plug-in plate 115. After the plug-in plate 115 is inserted 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.

[0105] The steel column module 200 has a simple structure and is easy to assemble and weld, possessing the advantages of the aforementioned steel column connection structure 100. During installation, the steel column module is vertically positioned, with the steel column connection structure 100 located at the top of the second steel column 210. The cross-sectional dimension of the first steel column 110 is smaller than that of the second steel column 210, and the first steel column 110 protrudes from the top of the second steel column 210.

[0106] When the upper and lower steel column modules are connected at the ends, the upper steel column module is fitted onto the steel column connection structure 100 of the lower steel column module, which facilitates the second steel column 210 of the upper steel column module to be fitted onto the steel column connection structure 100 of the lower steel column module.

[0107] For ease of connection, the first insertion slot 112 of the first steel column 110 and the second insertion slot 212 of the second steel column 210 are optionally coplanar, so that the insertion plate 115 can be inserted into the first insertion slot 112 and the second insertion slot 212 at the same time.

[0108] 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 plate 115 is matched with the first plug groove 112 of the first steel column 110, and the two sides of the plug plate 115 are matched with the second plug groove 212 of the second steel column 210.

[0109] In order to ensure that the upper and lower steel column modules can be smoothly connected, the relative positions of the connecting ends of the second steel column 210 of the upper and lower steel column modules can be adjusted according to actual needs.

[0110] Optionally, the steel column connection structure 100 can be set at the middle position of the second steel column 210, that is: the first insertion groove 112 opened on the first steel column 110 is coplanar with the central axis of the first steel column 110, and the second insertion groove 212 opened on the second steel column 210 is coplanar with the central axis of the second steel column 210.

[0111] Understandably, provided that the first insertion groove 112 of the first steel column 110 is coplanar with the central axis of the first steel column 110, the first insertion groove 112 can be perpendicular to the side wall of the first steel column 110; it can also be inclined and have an angle with the side wall of the first steel column 110; or, the first insertion groove 112 can be opened at the diagonal position of the first steel column 110.

[0112] Similarly, provided that the second insertion groove 212 of the second steel column 210 is coplanar with the central axis of the second steel column 210, the second insertion groove 212 can also be perpendicular to the side wall of the second steel column 210; it can also be inclined and have an angle with the side wall of the second steel column 210; or, the second insertion groove 212 can be opened at the diagonal position of the second steel column 210.

[0113] The steel column module 200 provided in this application embodiment has the beneficial effects of the steel column connection structure 100 described above, which will not be elaborated here.

[0114] This application embodiment also provides a steel column forming equipment 300, which is used to prepare the above-mentioned steel column connection structure 100 or steel column module 200.

[0115] Please refer to Figure 7 The diagram shown is a structural schematic of the steel column forming equipment 300.

[0116] 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.

[0117] 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 the end of the first steel column 110 away from the first insertion groove 112, and the pushing mechanism 330 is used to clamp the insertion plate 115 and drive the insertion plate 115 to move along the axial direction of the first steel column 110 so that the insertion plate 115 is inserted into the first insertion groove 112 of the first steel column 110.

[0118] 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 insertion groove protrude. 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 insertion plate close to the end of the second steel column with the second insertion groove. The pushing mechanism 330 drives the steel column connecting structure to move along the axial direction of the second steel column so that the insertion plate is inserted into the second insertion groove of the second steel column.

[0119] It is understood that, in alternative embodiments, the clamping chuck mechanism in the steel column forming equipment may also clamp the insertion plate, and the pushing mechanism clamps the end of the first steel column away from the first insertion slot, and drives the first steel column to move along its own axial direction, so that the first steel column is inserted and fixed with the insertion plate. Alternatively, the clamping chuck mechanism in the steel column forming equipment may also clamp the end of the steel column connecting structure away from the insertion plate, and the pushing mechanism clamps the second steel column, and brings the end of the second steel column with the second insertion slot close to the end of the insertion plate, and the pushing mechanism drives the second steel column to move along its own axial direction, so that the second steel column is inserted and fixed with the insertion plate of the steel column connecting structure.

[0120] This application does not limit the specific scheme for using the steel column forming equipment 300 to prepare the steel column connection structure 100 or the steel column module 200, but determines it according to actual needs and convenience.

[0121] The steel column forming equipment 300 provided in this application embodiment has a reasonable structural design. One assembly is clamped by the clamping chuck mechanism 320, and the other assembly is clamped and driven by the pushing mechanism 330 to move along the preset assembly direction until the two assemblies are connected. The pushing operation is convenient, which can improve the assembly efficiency while ensuring the assembly quality, and is also conducive to realizing fully automated production.

[0122] The following section describes the specific structure of the steel column forming equipment 300, taking the preparation of the steel column connection structure 100 by the steel column forming equipment 300 provided in the embodiments of this application as an example.

[0123] Please refer to Figure 8 The diagram shown is a first-person view of the push mechanism 330.

[0124] Specifically, the pushing mechanism 330 may include a first driving cylinder 3301, a first substrate 3303, a second substrate 3305 and a third substrate 3307 fixedly connected.

[0125] The first drive cylinder 3301 and the first base plate 3303 are fixedly connected to the frame 310. The first base plate 3303 can be a U-shaped structure, including two opposing side walls. First rollers 3311 are rotatably mounted on the two side walls of the first base plate 3303. The central axis of the first rollers 3311 is horizontal, allowing them to rotate vertically. Second base plates 3305 and 3307 can be fixed to the two 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 vertical, allowing it to rotate horizontally. A third roller 3315 is rotatably mounted on the third base plate 3307. The central axis of the third roller 3315 is vertical, allowing it to rotate horizontally.

[0126] After the plug-in plate 115 is installed on the pushing mechanism 330, the first roller 3311 of the pushing mechanism 330 is adapted to the bottom wall of the plug-in plate 115, and the second roller 3313 and the third roller 3315 are adapted to the side wall of the plug-in plate 115.

[0127] The first roller 3311 on the first substrate 3303, the second roller 3313 on the second substrate 3305, and the third roller 3315 on the third substrate 3307 cooperate with each other to clamp the insertion plate 115. The first roller 3311 rolls with the bottom wall of the insertion plate 115, and the second roller 3313 and the third roller 3315 roll with the side walls of the insertion plate 115. The first drive cylinder 3301 pushes the insertion plate 115. Under the force of the first drive cylinder 3301 and the rolling cooperation of the first roller 3311, the second roller 3313, and the third roller 3315, the insertion plate 115 moves toward the end of the first steel column with the first insertion groove, so that the insertion plate 115 is inserted into the first insertion groove of the first steel column.

[0128] To accommodate connectors of different sizes, the third roller 3315 on the third substrate 3307 may optionally be configured as an adjustable structure.

[0129] Specifically, please refer to Figure 9 The diagram shown is a structural schematic of the push mechanism 330 from a second perspective.

[0130] The pushing mechanism 330 may also include a second driving cylinder 3321, which is fixedly connected to the third base plate 3307, and a third roller 3315 is rotatably disposed at the driving end of the second driving cylinder 3321.

[0131] To further provide multiple third rollers 3315 at the drive end of the second drive cylinder 3321, the drive end of the second drive cylinder 3321 can also be fixedly connected to the mounting plate 3323. Multiple third rollers 3315 are rotatably mounted on the mounting plate 3323.

[0132] Optionally, there can be multiple first rollers 3311, second rollers 3313, and third rollers 3315, arranged sequentially. The rollers and the insertion plate 115 experience rolling friction, which reduces the frictional resistance of the insertion plate 115 as it moves axially along the first steel column under the drive of the first driving cylinder 3301, thus facilitating the sliding of the insertion plate 115 under the action of the first driving cylinder 3301.

[0133] Furthermore, in order to position the plug-in plate 115 from the top and prevent it from dislodging from above during movement, alternatively, please refer to... Figure 10 The diagram shown is a structural schematic of the push mechanism 330 from a third-person perspective.

[0134] Specifically, the pushing mechanism 330 may also include a third drive cylinder 3325, a connecting rod 3327, and a fourth roller 3329.

[0135] The third drive cylinder 3325 is fixedly connected to the frame 310. The first end of the connecting rod 3327 is hinged to the drive end of the third drive cylinder 3325, and the middle position of the connecting rod 3327 is hinged to the frame 310. The second end of the connecting rod 3327 is rotatably equipped with a fourth roller 3329. The third drive cylinder 3325 drives the fourth roller 3329 to abut against or move away from the top wall of the plug-in plate 115 through the connecting rod 3327.

[0136] For example: when the third drive cylinder 3325 extends, the first end of the connecting rod 3327 connected to the third drive cylinder 3325 rotates upward (in... Figure 10 From the perspective of counterclockwise rotation), the second end of the fourth roller 3329 rotates downwards (in... Figure 10 From the perspective of [the camera], it rotates counterclockwise, while simultaneously driving the fourth roller 3329 to press against the top wall of the plug plate 115, thus defining the position of the plug plate 115 from the top.

[0137] When the third drive cylinder 3325 retracts, the first end of the connecting rod 3327 connected to the third drive cylinder 3325 rotates downward (in... Figure 10 From the perspective of clockwise rotation), the second end of the fourth roller 3329 rotates upward (in... Figure 10 From the perspective of the viewpoint, rotating clockwise, it simultaneously drives the fourth roller 3329 away from the top wall of the plug-in plate 115, releasing the restriction on the plug-in plate 115 from the top.

[0138] 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. The first roller 3311, the second roller 3313, the third roller 3315 and the fourth roller 3329 limit the plug-in plate 115 from the bottom wall, side wall and top wall respectively. This can ensure that the plug-in plate 115 will not deviate during the movement along the axial direction of the first steel column 110, thereby ensuring smooth plugging and correct plugging position, which is conducive to improving the assembly quality in the subsequent assembly process.

[0139] Please refer to Figure 11 The diagram shown is a structural schematic of the clamping chuck mechanism 320.

[0140] Specifically, the chuck clamping mechanism 320 may include a drive mechanism 321, a turntable 323, a first pushing component 325, and a second pushing component 327.

[0141] The drive mechanism 321 is mounted on the frame 310 and is connected to the turntable 323 for driving the turntable 323 to rotate. To facilitate clamping the first steel column, a central through hole 3230 for the first steel column to pass through is provided in the middle of the turntable 323. A first pushing assembly 325 and a second pushing assembly 327 are located on the side of the turntable 323 opposite to the drive mechanism 321. The first pushing assembly 325 limits the first steel column in the first direction 103, and the second pushing assembly 327 limits the first steel column in the second direction 105.

[0142] exist Figure 11 From the perspective shown, optionally, the first direction 103 refers to the horizontal direction, and the second direction 105 refers to the vertical direction.

[0143] Optionally, the drive mechanism 321 and the turntable 323 can be connected by gear transmission. That is, the drive mechanism 321 may include a motor and a first gear. The motor is fixedly connected to the mounting bracket of the frame 310 and is located on the side of the mounting bracket away from the push mechanism 330. The power output end of the motor is connected to the first gear. The first gear and the motor are located on both sides of the mounting bracket. The outer peripheral wall of the turntable 323 is provided with multiple teeth that mesh with the first gear. The motor drives the turntable 323 with multiple teeth to rotate through the first gear.

[0144] In other optional embodiments, the drive 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 and the second gear are externally meshed, the motor drives the first gear to rotate, and the first gear drives the turntable 323 to rotate through the second gear.

[0145] This application does not limit the specific structure of the drive mechanism 321, but it depends on the actual needs, as long as the drive mechanism 321 can drive the turntable 323 to rotate.

[0146] Furthermore, the first pushing component 325 and the second pushing component 327 cooperate to limit the first steel column from four directions of the first steel column's cross-section. The first pushing component 325 pushes the first steel column along the first direction 103, and the second pushing component 327 pushes the first steel column along the second direction 105.

[0147] To avoid interference between the first pushing component 325 and the second pushing component 327 during the pushing process, optionally, the first pushing component 325 and the second pushing component 327 are misaligned in a direction perpendicular to the turntable 323. That is, the pushing path of the first pushing component 325 and the pushing path of the second pushing component 327 are not located on the same plane.

[0148] Optionally, the structures of the first pushing component 325 and the second pushing component 327 may be the same or different, depending on the actual needs. In the embodiments of this application, the structures of the first pushing component 325 and the second pushing component 327 are the same.

[0149] Please refer to Figure 12 The diagram shown is a structural schematic of the push-off component.

[0150] The first pushing assembly 325 and the second pushing assembly 327 may each include an abutment plate 3251, a pushing plate 3253, and a fourth driving cylinder 3255. The fourth driving cylinder 3255 is fixedly connected to the turntable 323. The pushing plate 3253 is fixedly connected to the driving end of the fourth driving cylinder 3255 and is used to cooperate with the side wall of the first steel column. The abutment plate 3251 is fixedly connected to the turntable 323, and the abutment plate 3251 and the fourth driving cylinder 3255 are located on both sides of the central through hole 3230 of the turntable 323. Under the action of the fourth driving cylinder 3255, the pushing plate 3253 pushes against the first steel column, and the abutment plate 3251 blocks the first steel column, thereby positioning the first steel column.

[0151] In alternative embodiments, the clamping chuck mechanism 320 may have other structures. For example, the clamping chuck mechanism may be a hollow columnar structure, rotatable relative to the frame, with a clamping mechanism disposed in the cavity of the clamping chuck mechanism. The first steel column is embedded in the cavity of the clamping chuck mechanism and clamped and fixed by the clamping mechanism, and 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.

[0152] This application does not limit the specific structure of the clamping chuck mechanism, as long as it can clamp and fix the first steel column and drive the first steel column to rotate.

[0153] The steel column forming equipment 300 provided in this application embodiment is reasonably designed. A clamping chuck mechanism 320 clamps and fixes the first steel column 110. A pushing mechanism 330 clamps and drives the insertion plate 115 towards the first steel column 110 until the insertion plate 115 is inserted into the first insertion slot 112 of the first steel column 110. This steel column forming equipment is convenient for clamping and pushing operations, and can accurately and easily achieve the insertion action, which is beneficial for subsequent welding operations. It improves assembly speed and efficiency while ensuring assembly quality, and is conducive to achieving fully automated production.

[0154] This application also provides a prefabricated steel structure 400 in its embodiments, please refer to it as well. Figure 13 and Figure 14 , Figure 13 The diagram shown is a structural schematic of a 400-type prefabricated steel structure. Figure 14 The image shown is a cross-sectional view of the connection between the upper steel column module 420 and the lower steel column module 410.

[0155] 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.

[0156] After installation, the second steel column 210 of the upper steel column module 420 is fitted onto 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.

[0157] For example, please refer to Figure 14 The prefabricated steel structure 400 includes two steel column modules, namely 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 located at the top of the second steel column 210. During installation, the second steel column 210 of the upper steel column module 420 is fitted onto the first steel column 110 of the lower steel column module 410, and the second steel column 210 of the upper steel column module 420 and the second steel column 210 of the lower steel column module 410 abut against each other.

[0158] After installation, the protruding steel bars 117 on the outer side wall of the first steel column 110 face the inner side wall of the second steel column 210, which helps to improve the tensile strength after the cement is poured.

[0159] The prefabricated steel structure 400 has the same beneficial effects as the steel column module 200 mentioned above, which will not be elaborated here.

[0160] This application also provides a precast shear wall 500 in this embodiment; please refer to [link / reference]. Figure 15 The diagram shown is a structural schematic of the first type of precast shear wall 500.

[0161] Specifically, the precast shear wall 500 may include a shear wall body 510 and the aforementioned steel column modules 200. The shear wall body 510 has a receiving cavity. There are two steel column modules 200, which are fixedly connected to both sides of the shear wall body 510 along its length. The shear wall body 510 and the two steel column modules 200 enclose a wall cavity 515 for cast-in-place concrete.

[0162] The shear wall body 510 includes a receiving cavity, and the shear wall body 510 and two steel column modules 200 located at its two ends enclose a wall cavity 515. This wall cavity 515 is used to accommodate the concrete cast-in-place within the precast shear wall 500 on the construction site, allowing the shear wall body 510 and the steel column modules 200 to be formed into a shear wall. Once the concrete is poured into the wall cavity 515 and solidifies, a shear wall is formed.

[0163] like Figure 15 As shown, two steel column modules 200 are fixedly connected to both sides of the shear wall body 510 along its length and are located in the receiving cavity of the shear wall body 510. The two sides of the shear wall body 510 along its length refer to the left and right sides of the shear wall body 510 in the installation / use state. The geometry of the prefabricated shear wall 500 is defined by the shear wall body 510.

[0164] Furthermore, the shear wall body 510 may include an inner membrane shell 5102 and an outer membrane shell 5104 arranged opposite to each other 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 inner membrane shell 5102, the outer membrane shell 5104, and the two steel column modules 200 enclose the wall cavity 515 from four directions: front, back, left, and right.

[0165] Please continue to refer to Figure 15 As shown in this embodiment, two steel column modules 200 are fixedly connected to both sides of the shear wall body 510 along its length and located in the receiving 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, bolt connection, or self-tapping screw connection, etc. The embodiments of the present invention do not specifically limit the above fixed connection method, and it depends on the actual needs.

[0166] Furthermore, the precast shear wall 500 may also include a shear wall steel frame 530.

[0167] 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 fixedly connected to two steel column modules 200 respectively.

[0168] Optionally, one side of the shear wall steel frame 530 along its 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 its 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 and second connectors respectively, forming a "sandwich" structure for the shear wall body 510. 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 an integral structure with a formwork-free design.

[0169] Optionally, the first connector and the second connector may include self-tapping screws, angle steel, channel steel or flat steel plate, etc.

[0170] The length direction of the shear wall steel frame 530 is the same as the lateral extension direction of the shear wall body 510. Steel column modules 200 are vertically fixedly connected to both ends of the shear wall steel frame 530 along its length direction. The two ends of the shear wall steel frame 530 along its length direction can be fixedly connected to the surface of the steel column modules 200 by welding.

[0171] Please see Figure 16 The diagram shown is a structural schematic of the second type of precast shear wall 500.

[0172] The precast shear wall of this structure has the same basic structure as the precast shear wall of the above structure. The difference is that 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 modules 200 are not located in the receiving cavity of the shear wall body 510. That is, the steel column modules 200 are fixedly connected to the ends of the shear wall body 510 along the length direction.

[0173] like Figure 16 As shown, 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 both ends of the shear wall body 510. The inner membrane shell 5102, the outer membrane shell 5104, and the two steel column modules 200 on the left and right sides enclose the wall cavity 515 from four directions: front, back, left, and right. 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 fixedly connected to the two steel column modules 200 respectively.

[0174] In summary, for the two types of precast shear walls 500 described above, when the shear wall formed after the precast shear wall 500 is poured with concrete 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 the interior, and the outer membrane shell 5104 of the shear wall body 510 is located on the side of the shear wall facing the exterior. Furthermore, the inner membrane shell 5102 and the outer membrane shell 5104 are arranged opposite to and parallel to each other, forming a wall cavity 515 enclosed by the inner membrane shell 5102, the outer membrane shell 5104, and the steel column modules 200 on both sides. That is to say, on the construction site, the concrete poured for the precast 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.

[0175] The inner membrane shell 5102 and outer membrane shell 5104 included in the shear wall body 510 can serve as wall side panels during the module production and hoisting stages and formwork during the construction stage. This allows the prefabricated room modules provided by the embodiments of the present invention to improve the rigidity of the modules during the production and transportation stages, and to eliminate the need for on-site shear wall reinforcement binding and formwork erection, thus saving construction steps and personnel.

[0176] This application also provides a modular building, including the aforementioned steel column connection structure, steel column module, or prefabricated steel structure.

[0177] This modular building has the same beneficial effects as the aforementioned steel column modules, which will not be elaborated here.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of this application.

[0179] Obviously, those skilled in the art can make various modifications and variations to this application without departing from the spirit and scope of this application. Therefore, if such modifications and variations fall within the scope of the claims of this application and their equivalents, this application also intends to include such modifications and variations.
