Prefabricated pipe column module forming equipment and pipe column forming method

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202310799727.X 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 assembly buildings, and in particular to a prefabricated pipe column module molding device and a pipe column molding method. Background Art

[0004] Modular assembly buildings refer to buildings that are prefabricated in factories, assembled at the construction site, and connected using steel structures to form a whole. They are more stable than traditional building structures and can greatly enhance the extensibility and load-bearing performance of steel structures.

[0005] In existing modular prefabricated buildings, the upper and lower layers of square columns are connected by plug-in connections. The ends of the columns are designed with plug-in structures. After the two layers of square columns are connected by the plug-in structure, concrete is poured into the columns to achieve a stable connection. To enhance the pull-out resistance of the connection between the upper and lower layers of square columns after concrete pouring, pull-out resistant components are usually added to the plug-in structure.

[0006] The existing method is to place a core protruding from the top of the lower square column, deposit solder on the outside of the core protrusion to form a strip-shaped protrusion, and deposit solder on the inside of the bottom of the upper square column to form a strip-shaped protrusion. However, due to the complex structure of the top of the square column and the narrow space at the bottom, welding can only be performed from the end of the square column, which is inconvenient, resulting in poor welding quality and low efficiency, and is not conducive to automated production.

[0107] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature identified as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0108] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediary; or internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0109] In an embodiment of the present application, a prefabricated tubular string module molding device is provided for preparing a prefabricated tubular string module. The structure of the prefabricated tubular string module is first introduced in detail.

[0110] Please refer to FIG. 1 , which is a schematic structural diagram of a prefabricated pipe string module 100 . Please refer to FIG. 2 , which is an exploded schematic diagram of the prefabricated pipe string module 100 .

[0111] Specifically, the prefabricated tubular module 100 may include a tubular body 110, a first tubular assembly 130, and a second tubular assembly 160. The tubular body 110 includes a first end and a second end opposite to each other. The first tubular assembly 130 and the second tubular assembly 160 are fixedly connected to both ends of the tubular body 110, respectively.

[0112] The first end of the tubular column body 110 is provided with a first insertion groove 113 (as shown in FIG. 2 ) along the axial direction. A first ridge 135 extending along a first predetermined direction 101 is provided on the outer sidewall of one end of the first tubular column assembly 130, and a plug plate 137 is provided along the axial direction of the other end. During connection, the plug plate 137 of the first tubular column assembly 130 is inserted into the first insertion groove 113 at the first end of the tubular column body 110, and the first tubular column assembly 130 is inserted into the tubular column body 110 and fixedly connected to the tubular column body 110 via the plug plate 137. A second ridge 163 extending along a second predetermined direction 103 is provided on the inner sidewall of the second tubular column assembly 160 (as shown in FIG. 2 ). The second tubular column assembly 160 is fixedly connected to the second end of the tubular column body 110.

[0113] It is understandable that the first preset direction 101 and the second preset direction 103 may be the same or different, and the first preset direction 101 forms an angle with the axial direction of the pipe string body 110, and the second preset direction 103 also forms an angle with the axial direction of the pipe string body 110. In order to improve the pull-out resistance of the connection point after the upper and lower prefabricated pipe string modules are sleeved together, the second ridge on the inner side wall of the second pipe string assembly in the upper prefabricated pipe string module can be extended in a horizontal direction, that is, in a direction that forms an angle with the axial direction of the pipe string body; the first ridge on the outer side wall of the first pipe string assembly in the lower prefabricated pipe string module can also extend in a horizontal direction, that is, in a direction that forms an angle with the axial direction of the pipe string body.

[0114] The prefabricated pipe column module 100 is designed by designing a complete pipe column into a structure in which three structural components are fixedly connected: a pipe column body 110, a first pipe column assembly 130, and a second pipe column assembly 160. Specifically, a first ridge 135 is first protruded on the outer wall of the first pipe column assembly 130. After the first pipe column assembly 130 is formed, the first pipe column assembly 130 is fixedly connected to the first end of the pipe column body 110 via a plug-in plate 137. A second ridge 163 is protruded on the inner wall of the second pipe column assembly 160. After the second pipe column assembly 160 is formed, the second pipe column assembly 160 is fixedly connected to the second end of the pipe column body 110. The prefabricated pipe column module 100 enhances the pull-out resistance between the connection points of the upper and lower prefabricated pipe column modules 100 by using the first ridge 135 of the first pipe column assembly 130 and the second ridge 163 of the second pipe column assembly 160. The first tubular column assembly 130 and the second tubular column assembly 160 can be formed separately and can be operated from both ends. Especially for the second tubular column assembly 160 with a narrow internal space, forming operations from both ends can not only reduce the forming difficulty but also improve the forming efficiency.

[0115] In the embodiment of the present application, for modular assembly building scenarios, the first pipe string assembly 130 can be welded to the first end of the pipe string body 110 via the plug plate 137, and the second pipe string assembly 160 can also be welded to the second end of the pipe string body 110. The present application does not limit the specific form of fixed connection, which can be determined according to the specific application scenario. For example, in other scenarios where strength requirements are not high, bolt connection, riveting, bonding, etc. can also be used.

[0116] The following is a detailed introduction to the technical solution provided in the embodiments of the present application in a modular assembly building scenario.

[0117] By first separately forming the first tubular column assembly 130 and the second tubular column assembly 160, the formed first tubular column assembly 130 is fixedly connected to the first end of the tubular column body 110, and the formed second tubular column assembly 160 is fixedly connected to the second end of the tubular column body 110, an integral module is finally formed, which is conducive to realizing automated production.

[0118] Optionally, the cross-sectional shape of the tubular body 110 may be rectangular, and accordingly, the cross-sectional shapes of the first tubular body assembly 130 and the second tubular body assembly 160 may also be rectangular. In other optional embodiments, the cross-sectional shapes of the tubular body 110, the first tubular body assembly 130, and the second tubular body assembly 160 may also be other structures, as long as the cross-sectional shapes of the second tubular body assembly 160 and the tubular body 110 are the same and the first tubular body assembly 130 can be embedded in the tubular body 110. This is not limited to this in the present application, and the following description assumes that the cross-sectional shape is rectangular.

[0119] The specific structure of the prefabricated pipe string module 100 is described in detail below.

[0120] The tubular body 110 is a long hollow tubular structure including a first end and a second end opposite to each other. The first end is used for being fixedly coupled with the first tubular assembly 130 , and the second end is used for being fixedly coupled with the second tubular assembly 160 .

[0121] Because the cross-sectional dimensions of the first tubular column assembly 130 are smaller than those of the tubular column body 110, the first tubular column assembly 130 is inserted into the first end of the tubular column body 110. To securely connect the first tubular column assembly 130 and the tubular column body 110, a first insertion groove 113 can be defined at the first end of the tubular column body 110, and a plug-in plate 137 is provided at the end of the first tubular column assembly 130. Both the plug-in plate 137 and the first insertion groove 113 are disposed along the axial direction of the tubular column body 110, and the first tubular column assembly 130 is inserted into the first insertion groove 113 of the tubular column body 110 via the plug-in plate 137.

[0122] Optionally, the size of the first plug-in slot 113 opened at the first end of the column body 110 is adapted to the size of the plug-in plate 137, that is, the thickness of the plug-in plate 137 is slightly smaller than the slot width of the first plug-in slot 113, the length of the plug-in plate 137 is slightly larger than the length of the first plug-in slot 113, and the width of the plug-in plate 137 is equal to or larger than the depth of the first plug-in slot 113, so as to facilitate the smooth insertion of the plug-in plate 137 into the first plug-in slot 113.

[0123] It is understandable that in other optional embodiments, the width dimension of the plug-in plate 137 can also be smaller than the depth dimension of the first plug-in slot 113. This application does not limit this dimension, as long as the first pipe column assembly 130 is plugged and fixed to the pipe column body 110 through the plug-in plate 137.

[0124] Please refer to FIG. 4 , which is a schematic structural diagram of a first structure of the first tubular string assembly 130 in the prefabricated tubular string module 100 .

[0125] Specifically, the first tube column assembly 130 may include a first tube column 133 , a first ridge 135 protruding from the outer wall of the first tube column 133 , a second plug-in groove 1331 axially opened at one end of the first tube column 133 , and a plug-in plate 137 plugged and fixed in the second plug-in groove 1331 .

[0126] Optionally, the first tubular column 133 may be a hollow tubular structure, with a second insertion slot 1331 defined axially along the sidewall of the first tubular column 133. The insertion plate 137 may be a rectangular fixing plate, the length of which should be greater than the length of the second insertion slot 1331 of the first tubular column 133, the thickness of which should be slightly less than the width of the second insertion slot 1331 of the first tubular column 133, and the width of the rectangular fixing plate 1631 may be equal to, greater than, or less than the depth of the second insertion slot 1331 of the first tubular column 133.

[0127] Furthermore, after the first tubular column 133 is plugged and secured to the tubular column body 110 via the plug-in plate 137, the first plug-in slot 113 of the tubular column body 110 and the second plug-in slot 1331 of the first tubular column 133 become coplanar. Since the first tubular column assembly 130 is plugged into the tubular column body 110, the center portion of the plug-in plate 137 mates with the second plug-in slot 1331 of the first tubular column 133, while the sides of the plug-in plate 137 mate with the first plug-in slot 113 of the tubular column body 110 (as shown in FIG. 1 ).

[0128] Optionally, the first insertion groove 113 of the tubular body 110 is coplanar with the central axis of the tubular body 110, and the second insertion groove 1331 of the first tubular body 133 is coplanar with the central axis of the first tubular body 133. That is, the first insertion groove 113 may be opened perpendicular to the sidewall of the tubular body 110 and pass through the central axis of the tubular body 110, or may be located at a diagonal position of the tubular body 110, or may be opened at an angle to the sidewall of the tubular body 110 and pass through the central axis of the tubular body 110.

[0129] Furthermore, the first tube column assembly 130 may further include a plurality of first ribs 1351 . The plurality of first ribs 1351 are spaced apart on the outer side wall of the first tube column 133 and extend along the first preset direction 101 to form first ridges.

[0130] The first predetermined direction 101 refers to a direction at an angle to the axis of the first tubular column 133. For example, the first rib 1351 extends in a direction perpendicular to the central axis of the first tubular column 133. The first ribs 1351 may be evenly or unevenly spaced. The first ribs 1351 may be provided on each outer wall of the first tubular column 133, or on only a portion of the outer walls. The first ribs 1351 may be secured to the outer wall of the first tubular column 133 by welding.

[0131] When multiple prefabricated pipe string modules are assembled in a sleeve-type manner, in order to facilitate the smooth sleeve connection between the upper prefabricated pipe string module and the lower prefabricated pipe string module, a guide piece can be optionally provided on the top of the lower prefabricated pipe string module to guide the upper prefabricated pipe string module and facilitate smooth sleeve connection.

[0132] Specifically, the first tubular column assembly 130 may further include a guide member, which is at least partially fixedly connected to the outer wall of the first tubular column 133 , and is used to adapt to the inner wall of the second tubular column assembly of another prefabricated tubular column module.

[0133] Please refer to FIG. 5 , which is a schematic structural diagram of a second structure of the first tubular string assembly 130 in the prefabricated tubular string module 100 .

[0134] The guide member may include a lug 1381 fixedly connected to the outer sidewall of the first tubular column 133 at a diagonal position. There may be at least two lugs 1381, two of which may be fixedly connected to the outer sidewall of the first tubular column 133 at a diagonal position, with the outermost lug 1381 being configured to mate with the inner sidewall of the upper prefabricated tubular column module.

[0135] In order to further achieve the guiding effect, optionally, the side of the lug 1381 away from the first tube column 133 can be designed as an arc structure.

[0136] By protruding a support ear 1381 with an arc-shaped outer edge on the outer side wall of the first pipe column 133 at a diagonal position, the upper prefabricated pipe column module and the lower prefabricated pipe column module can be smoothly connected.

[0137] Please refer to FIG. 6 , which is a schematic structural diagram of a third structure of the first tubular string assembly 130 in the prefabricated tubular string module 100 .

[0138] Specifically, the guide member may include a fixedly connected guide cone 1383 and a guide column 1385, wherein the guide column 1385 is a slender rod-shaped structure, and the guide column 1385 is fixedly connected to the outer wall of the diagonal position of the first tube column 133, and the guide cone 1383 is connected to the end of the guide column 1385 and is located at the end of the first tube column 133 away from the second plug-in slot 1331.

[0139] Optionally, there may be multiple guide posts 1385, each of which is fixed to the outer sidewalls of the first tube post 133 at diagonal positions (when the first tube post 133 is a quadrangular prism, there are four guide posts 1385, and the four guide posts 1385 are fixed to the outer sidewalls of the four corners of the quadrangular prism in a one-to-one manner). The guide cone 1383 may include a conical piece connected to the guide posts 1385 in a one-to-one manner, and the side of the conical piece away from the guide posts 1385 intersects at the middle position, so that the guide cone 1383 can have a structure that is lower on the outside and higher in the middle.

[0140] 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.

[0141] Please refer to FIG. 7 , which is a schematic structural diagram of a first structure of the second tubular string assembly 160 in the prefabricated tubular string module 100 .

[0142] The second tubular column assembly 160 may include a second tubular column 161 and a connecting assembly, which is disposed on the inner sidewall of the second tubular column 161. The sidewall of the second tubular column 161 defines a plurality of fixing grooves 1611, and one side of the connecting assembly has a concave-convex shape to form a plurality of second ridges 163 extending along the second predetermined direction 103. During installation, the other side of the connecting assembly is disposed on the inner sidewall of the second tubular column 161, and the connecting assembly and the second tubular column 161 are secured from the outside of the second tubular column 161 at the fixing grooves 1611. It is understood that the securing method here may be welding.

[0143] Please refer to FIG8 , which is a schematic structural diagram of a first structure of a connection component.

[0144] Specifically, the connection assembly may include a fixing plate 1631 and a second rib 1633 , and the second rib 1633 is fixed to the inner side wall of the second pipe column 161 through the fixing plate 1631 .

[0145] Optionally, there are multiple second ribs 1633. The fixing plate 1631 includes a first side surface and a second side surface facing away from each other. The multiple second ribs 1633 are sequentially fixed to the first side surface of the fixing plate 1631 at intervals. The multiple second ribs 1633 extend along the second predetermined direction 103 to form a second ridge. The multiple second ribs 1633 are fixed to the fixing plate 1631 to form an integral whole. The second side surface of the fixing plate 1631 is then attached to the inner sidewall of the second tubular column 161. Finally, the fixing plate 1631 is fixed from the outer sidewall. Optionally, in this embodiment of the present application, welding can be used for fixing.

[0146] Optionally, the fixing plate 1631 may be a thin-walled fixing plate, whose shape matches the inner wall shape of the second tube column 161, for example, a rectangular structure. The plurality of second ribs 1633 are sequentially spaced apart, so that the first side surface of the fixing plate 1631 forms a concave-convex shape.

[0147] Optionally, multiple second ribs 1633 are evenly welded to the first side surface of the fixing plate 1631 , and each second rib 1633 extends along the second preset direction 103 , and multiple second ribs 1633 are distributed in sequence along a direction perpendicular to the second preset direction 103 .

[0148] Please refer to FIG9 , which is a schematic diagram of the second structure of the connection component.

[0149] Specifically, the connection assembly may include a fixing plate 1631, which includes a first side surface and a second side surface facing away from each other. The first side surface is provided with a plurality of second ridges 163 extending along the second predetermined direction 103. During installation, the second side surface of the fixing plate 1631 is positioned on the inner sidewall of the second tube column 161, and the fixing plate 1631 is secured to the second tube column 161 from the outside of the second tube column 161 at the fixing groove 1611.

[0150] Optionally, the second rib 163 and the fixing plate 1631 may be integrally formed, for example, by mold casting, or extrusion molding, etc., which is not limited in the embodiment of the present application.

[0151] In other optional embodiments, multiple grooves may be sequentially spaced apart on the first side surface of the fixing plate 1631, extending along the second predetermined direction 103, with a second ridge 163 formed between any two adjacent grooves 1635. For example, this may be formed by milling. Specifically, multiple grooves 1635 may be milled on a single fixing plate 1631, such that any two adjacent grooves 1635 are separated by a second ridge 163.

[0152] 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 can be provided on each inner sidewall of the second tubular column 161. That is, the second tubular column 161 includes multiple inner sidewalls, each of which is provided with a connection assembly, thereby enhancing the pullout resistance from all sides.

[0153] In this embodiment, the second rib 1633 is fixed to the fixing plate 1631, a fixing groove 1611 is formed in the side wall of the second tube column 161, and the fixing plate 1631 and the second tube column 161 are fixed together through the fixing groove 1611, thereby achieving indirect fixing of the second rib 1633 to the inner side wall of the second tube column 161 via the fixing plate 1631. Alternatively, welding can be used for fixing, which is convenient and easy to operate, and can not only increase welding speed but also improve welding efficiency, thereby facilitating further automated production.

[0154] Please refer to Figure 10, which is a schematic diagram showing a second structure of the second tubular string assembly 160 in the prefabricated tubular string module 100. Please refer to Figure 11, which is an exploded schematic diagram showing the second structure of the second tubular string assembly 160.

[0155] Specifically, the second tubular column assembly 160 may include a second tubular column 161 and a third tubular column 165. Both the second tubular column 161 and the third tubular column 165 are hollow cylindrical structures. The sidewall of the second tubular column 161 is provided with a fixing groove 1611 extending along the second preset direction 103. The third tubular column 165 includes a plurality of crossbeams 1651 extending along the second preset direction 103. During installation, the third tubular column 165 is embedded within the second tubular column 161, with the axial direction of the second tubular column 161 being aligned with the axial direction of the third tubular column 165. The fixing groove 1611 of the second tubular column 161 is aligned with at least a portion of the crossbeams 1651 of the third tubular column 165. The crossbeams 1651 are then fixed to the second tubular column 161 at the fixing groove 1611 from the outside of the second tubular column 161, thereby securing the second tubular column 161 to the third tubular column 165.

[0156] It is understandable that the fixation here can be performed by welding. By adopting two hollow cylindrical structures of the second pipe column 161 and the third pipe column 165, the third pipe column 165 includes a plurality of cross beams 1651, and the side wall of the second pipe column 161 is provided with a plurality of fixing grooves 1611. The third pipe column 165 is embedded in the second pipe column 161, and the cross beams 1651 of the third pipe column 165 correspond to the fixing grooves 1611 of the second pipe column 161. Then, the cross beams 1651 and the second pipe column 161 are welded and fixed at the fixing grooves 1611 from the outside of the second pipe column 161. After welding, the cross beams 1651 of the third pipe column 165 protrude from the inner side wall of the second pipe column 161, forming a concave-convex structure. The second pipe column assembly 160 provided in the embodiment of the present application is convenient to assemble and weld, has a simple structure, and is cleverly designed. It greatly improves the convenience of welding, and improves the welding speed and production efficiency while meeting the pull-out resistance, which is conducive to the realization of automated production.

[0157] Please refer to FIG. 12 , which is a schematic structural diagram of a first structure of the third tube column 165 .

[0158] Specifically, the third pipe column 165 further includes a vertical beam 1653 , which is cross-connected with the horizontal beam 1651 to form a hollow columnar structure.

[0159] The vertical beams 1653 extend axially. There are multiple vertical beams 1653, each parallel but not coplanar. The horizontal beams 1651 connect two adjacent vertical beams 1653. The two adjacent vertical beams 1653 and the horizontal beam 1651 located therebetween form a plane, and the multiple planes form a hollow cylindrical structure. The vertical beams 1653 extend axially, while the horizontal beams 1651 extend along the second predetermined direction 103. The axial direction forms an angle with the second predetermined direction 103.

[0160] Furthermore, a plurality of transverse beams 1651 are provided between any two adjacent vertical beams 1653 , and the plurality of transverse beams 1651 between any two adjacent vertical beams 1653 are sequentially spaced apart along the axial direction.

[0161] Optionally, the second preset direction 103 may be perpendicular to the axial direction, that is, in the structure shown in FIG. 12 , in use, all horizontal beams 1651 extend in the horizontal direction, and all vertical beams 1653 extend in the vertical direction.

[0162] Each sidewall of the second tubular column 161 is provided with a plurality of fixing grooves 1611. The fixing grooves 1611 on the same sidewall are spaced apart axially and correspond to the crossbeams 1651 of the third tubular column 165. This facilitates securing the corresponding crossbeam 1651 at each fixing groove 1611 from the outside of the second tubular column 161, optionally by welding.

[0163] In order to further improve the connection stability between the third tube column 165 and the second tube column 161 , in addition to fixing them at the position of the fixing groove 1611 , the end of the third tube column 165 and the end of the second tube column 161 may also be fixed.

[0164] Please refer to FIG. 13 , which is a schematic structural diagram of a second structure of the third tube column 165 .

[0165] Specifically, the third tube column 165 is a rectangular fixed plate having a plurality of through slots 1655 extending along the second predetermined direction 103, so that a crossbeam 1651 is formed between two adjacent through slots 1655. The rectangular fixed plate is bent multiple times along the second predetermined direction 103, and after bending, the ends are fixedly connected to form a hollow columnar structure.

[0166] For example, a hollow rectangular columnar structure can be formed by bending a rectangular fixing plate having multiple through slots 1655, for example, three times, so that a right angle is formed between two adjacent surfaces after bending, and welding the first surface and the fourth surface end to end.

[0167] Then, the third pipe column 165 is embedded in the second pipe column 161, and the fixing groove 1611 provided on the second pipe column 161 is staggered with the through groove 1655 on the third pipe column 165, that is, the fixing groove 1611 corresponds to the crossbeam 1651. At the position of the fixing groove 1611, the crossbeam 1651 and the second pipe column 161 are welded and fixed from the outside of the second pipe column 161.

[0168] The prefabricated tubular column module 100 provided in the embodiment of the present application is designed as a monolithic tubular column structure comprising a tubular column body 110, a first tubular column assembly 130, and a second tubular column assembly 160, wherein the first tubular column assembly 130 and the second tubular column assembly 160 can be fixed from both ends and formed independently. The formed first tubular column assembly 130 is plugged and fixed to the first end of the tubular column body 110 via a plug-in plate 137 and then fixed at the plug-in position. The formed second tubular column assembly 160 is fixed to the second end of the tubular column body 110. The operation is convenient and the assembly is easy. By "providing a second ridge 163 on the inner side wall of the second tubular column assembly 160", it can be converted into: the first way is: the structure of the second tubular column 161 and the connecting assembly, the connecting assembly may include a fixing plate 1631 and a second rib 1633, the second rib 1633 is fixed to the first side surface of the fixing plate 1631, and the fixing plate 1631 is fixed to the inner side wall of the second tubular column 161, that is, the second rib 1633 is fixed to the inner side wall of the second tubular column 161 through the fixing plate 1631. The second way is: two tubular columns (i.e., the second tubular column 161 and the third tubular column 165), one large and one small, are sleeved together, the tubular column located on the inner side (the third tubular column 165) is provided with a plurality of cross beams 1651 extending along the second preset direction 103, and the tubular column located on the outer side (the second tubular column 161) is provided with a fixing groove 1611 extending along the second preset direction 103. After the two pipe strings are socketed, the fixing groove 1611 of the outer pipe string corresponds to the crossbeam 1651 of the inner pipe string, and the crossbeam 1651 of the inner pipe string is fixed to the outer pipe string through the position of the fixing groove 1611, so that the second pipe string 161 is fixed to the third pipe string 165 with the crossbeam 1651, and the crossbeam 1651 with anti-pullout performance is indirectly fixed to the inner wall of the second pipe string 161.

[0169] The prefabricated pipe column module 100 has a simple structure, ingenious design, convenient operation, and easy socketing, which can improve the molding speed and production efficiency, and is conducive to further realizing automated production.

[0170] The specific structure of a prefabricated tubular string module molding device provided in an embodiment of the present application is introduced below. The prefabricated tubular string module molding device is used to prepare the above-mentioned prefabricated tubular string module.

[0171] Please refer to FIG. 14 , which is a schematic structural diagram of a prefabricated pipe string module forming device 300 .

[0172] Specifically, the prefabricated pipe string module forming equipment 300 may include a ground rail 310, a first workbench 330, a second workbench 350, and a fixing assembly. The ground rail 310 is fixed to the ground and includes a first end and a second end opposite to each other. The first workbench 330 is slidably disposed on the first end of the ground rail 310, and the second workbench 350 is slidably disposed on the second end of the ground rail 310.

[0173] The first workbench 330 may include a first frame 331, a first clamping chuck mechanism 333, and a first pushing mechanism 335. The first clamping chuck mechanism 333 is rotatably mounted on the first frame 331, and the first pushing mechanism 335 is mounted on the first frame 331. The second workbench 350 may include a second frame 351, a second clamping chuck mechanism 353, and a second pushing mechanism 355. The second clamping chuck mechanism 353 is rotatably mounted on the second frame 351, and the second pushing mechanism 355 is mounted on the second frame 351. The first clamping chuck mechanism 333 and the second clamping chuck mechanism 353 cooperate with each other to clamp and fix the pipe string body 110. Specifically, the first clamping chuck mechanism 333 clamps the first end of the pipe string body 110, and the second clamping chuck mechanism 353 clamps the second end of the pipe string body 110. The first pushing mechanism 335 is used to clamp the first tubular column assembly 130 and drive the first tubular column assembly 130 to move axially along the tubular column body 110. The second pushing mechanism 355 is used to clamp the second tubular column assembly 160 and drive the second tubular column assembly 160 to move axially along the tubular column body 110. When the first pushing mechanism 335 drives the first tubular column assembly 130 to a target position (i.e., the plug-in plate is plugged into the first plug-in slot at the first end of the tubular column body 110 (not shown in FIG. 14 )), the second pushing mechanism 355 drives the second tubular column assembly 160 to a target position (i.e., the end of the second tubular column assembly 160 is aligned with the second end of the tubular column body 110). The fixing assembly securely connects the first tubular column assembly 130 to the connection point at the first end of the tubular column body 110 and securely connects the second tubular column assembly 160 to the connection point at the second end of the tubular column body 110.

[0174] The prefabricated pipe string module forming apparatus 300 utilizes the aforementioned pipe string forming method to prepare the aforementioned prefabricated pipe string module 100. The first workbench 330 and the second workbench 350 can slide toward a central position along the ground rail 310, allowing the first clamping chuck mechanism 333 and the second clamping chuck mechanism 353 to cooperate and clamp and secure the pipe string body 110. The first pushing mechanism 335 clamps the first pipe string assembly 130 and drives the first pipe string assembly 130 toward the pipe string body 110 until the plug-in plate (not shown) of the first pipe string assembly 130 is inserted into the first plug-in slot at the first end of the pipe string body 110. The second pushing mechanism 355 clamps the second pipe string assembly 160 and drives the second pipe string assembly 160 toward the pipe string body 110 until the end of the second pipe string assembly 160 corresponds to and abuts the second end of the pipe string body 110.

[0175] Optionally, the fixing assembly may be a welding gun, which is used to weld the first pipe column assembly 130 to the connection position of the first end of the pipe column body 110 and the second pipe column assembly 160 to the connection position of the second end of the pipe column body 110 .

[0176] It is understandable that in other application scenarios, for example, scenarios where the molding strength requirement is not high, the fixing components may also be fixed by bolt connection, riveting, welding, bonding, etc. This application does not limit the specific application scenario and fixing method, and the appropriate fixing method is selected according to the actual situation of the application scenario.

[0177] In the modular assembly building field scenario, the prefabricated pipe column module forming equipment provided in the embodiment of the present application uses a fixing component to first spot weld the connection position between the pipe column body 110 and the plug-in plate 137, and spot weld the connection position between the pipe column body 110 and the second pipe column assembly 160 to complete the preliminary fixation; then the first pushing mechanism 335 releases the first pipe column assembly 130, and the second pushing mechanism 355 releases the second pipe column assembly 160, and the first pushing mechanism 335 and the second pushing mechanism 355 are evacuated respectively; finally, the fixing component cooperates with the first clamping chuck mechanism 333 and the second clamping chuck mechanism 353 to fully weld the connection position between the pipe column body 110 and the first pipe column assembly 130 and the second pipe column assembly 160. During the specific welding process, the connection parts that are convenient for welding (for example, positions without obstruction or interference above) can be welded first, and then the first clamping chuck mechanism 333 and the second clamping chuck mechanism 353 cooperate to rotate the pipe column body 110 to adjust the welding position, so as to facilitate the fixing assembly to fully weld all positions that need to be welded at the end of the pipe column body 110.

[0178] The prefabricated pipe column module molding device 300 is rationally designed, convenient to operate, and easy to mold. It can improve the molding speed and assembly efficiency while ensuring the molding quality, and can also realize fully automated production.

[0179] The specific structure of the prefabricated pipe string module forming device 300 is described in detail below.

[0180] Alternatively, referring to Figure 15 , which is a schematic diagram of a rack structure, the first rack 331 and the second rack 351 may have the same structure, and may both include a rack body 320 and a fixing frame 322 that are fixedly connected.

[0181] After installation, the frame body 320 is slidably mounted on the floor rail 310, and the fixing frame 322 is fixedly connected to the top of the frame body 320. The first pushing mechanism 335 is mounted on the frame body 320 of the first frame 331, and the first clamping chuck mechanism 333 is rotatably mounted on the fixing frame 322 of the first frame 331. The second pushing mechanism 355 is mounted on the frame body 320 of the second frame 351, and the second clamping chuck mechanism 353 is rotatably mounted on the fixing frame 322 of the second frame 351.

[0182] The first clamping chuck mechanism 333 can rotate relative to the fixed frame 322 of the first frame 331, and the first clamping chuck mechanism 333 clamps and fixes the first end of the pipe column body 110; the second clamping chuck mechanism 353 can rotate relative to the fixed frame 322 of the second frame 351, and the second clamping chuck mechanism 353 clamps and fixes the second end of the pipe column body 110.

[0183] The first clamping chuck mechanism 333 and the second clamping chuck mechanism 353 cooperate with each other to not only clamp and fix the pipe column body 110 to suspend the pipe column body 110 in the air, but also drive the pipe column body 110 to rotate to adjust different fixing surface positions.

[0184] The first clamping chuck mechanism 333 and the second clamping chuck mechanism 353 cooperate with the fixing assembly to conveniently fix the connection positions between the two ends of the pipe column body 110 and the first pipe column assembly 130 and the second pipe column assembly 160 .

[0185] Optionally, the structures of the first clamping chuck mechanism 333 and the second clamping chuck mechanism 353 may be identical or different, depending on actual needs. In the embodiment of the present application, the structures of the first clamping chuck mechanism 333 and the second clamping chuck mechanism 353 are identical. The specific structure of the clamping chuck mechanism in the prefabricated pipe string module molding device 300 is described in detail below.

[0186] Please refer to FIG16 , which is a schematic structural diagram of the clamping chuck mechanism.

[0187] Specifically, the clamping chuck mechanism may include a driving mechanism, a rotating disk 342 , a first resisting assembly 344 and a second resisting assembly 346 .

[0188] The drive mechanism is mounted on the fixed frame 322 and is in transmission connection with the rotary disk 342, driving the rotary disk 342 to rotate. To facilitate clamping the pipe body, a central through-hole 3420 is provided in the middle of the rotary disk 342 for receiving the pipe body. A first push assembly 344 and a second push assembly 346 are disposed on the side of the rotary disk 342 facing away from the drive mechanism. The first push assembly 344 is used to limit the pipe body in the first direction 301, while the second push assembly 346 is used to limit the pipe body 110 in the second direction 303.

[0189] In the viewing angle shown in FIG. 16 , optionally, the first direction 301 refers to the horizontal direction, and the second direction 303 refers to the vertical direction.

[0190] Optionally, the driving mechanism and the turntable 342 can be connected through gear transmission, that is, the driving mechanism can include a first motor and a first gear 341, the first motor is fixedly connected to the side of the fixed frame 322 away from the first pushing mechanism 335, the power output end of the first motor is connected to the first gear 341, the first gear 341 and the first motor are respectively located on both sides of the fixed frame 322, and the outer peripheral wall of the turntable 342 is provided with a plurality of teeth 3421 that mesh with the first gear 341. The first motor drives the turntable 342 having the plurality of teeth 3421 to rotate through the first gear 341.

[0191] In other optional embodiments, the driving mechanism may further include a second gear, the turntable 342 is a plate-shaped structure, the turntable 342 is fixedly connected to the second gear, the first gear 341 is externally engaged with the second gear, the first motor drives the first gear 341 to rotate, and the first gear 341 drives the turntable 342 to rotate through the second gear.

[0192] The present application does not limit the specific structure of the driving mechanism, which depends on actual needs, as long as the driving mechanism can drive the turntable 342 to rotate.

[0193] Furthermore, the first push assembly 344 and the second push assembly 346 cooperate to limit the position of the tubular body from four directions of the tubular body cross section. Since the first push assembly 344 pushes the tubular body 110 along the first direction 301 and the second push assembly 346 pushes the tubular body 110 along the second direction 303, in order to avoid interference between the first push assembly 344 and the second push assembly 346 during the pushing process, the first push assembly 344 and the second push assembly 346 are optionally offset in a direction perpendicular to the turntable 342, that is, the pushing path of the first push assembly 344 and the pushing path of the second push assembly 346 are not located in the same plane.

[0194] Optionally, the structures of the first push component 344 and the second push component 346 can be the same or different, depending on actual needs. In the embodiment of the present application, the structures of the first push component 344 and the second push component 346 are the same.

[0195] Please refer to Figure 17, which shows a schematic structural diagram of the push assembly. The first push assembly 344 and the second push assembly 346 can each include a push plate 3450, a push plate 3453, and a first drive cylinder 3455. The first drive cylinder 3455 is fixedly connected to the turntable 342, and the push plate 3453 is fixedly connected to the drive end of the first drive cylinder 3455. The push plate 3453 is used to cooperate with the side wall of the pipe column body. The push plate 3450 is fixedly connected to the turntable 342, and the push plate 3450 and the first drive cylinder 3455 are respectively located on both sides of the central through hole 3420 of the turntable 342. Under the action of the first drive cylinder 3455, the push plate 3453 pushes the pipe column body, and the push plate 3450 is used to resist the pipe column body, thereby positioning the pipe column body.

[0196] Please refer to FIG. 18 , which is a structural diagram of the first pushing mechanism 335 from a first perspective.

[0197] Specifically, the first pushing mechanism 335 may include a fourth driving cylinder 3350 , a first base plate 3351 , a second base plate 3353 and a third base plate 3355 that are fixedly connected.

[0198] The fourth drive cylinder 3350 and the first base plate 3351 are respectively fixedly connected to the frame body 320 of the first frame. The first base plate 3351 can be a U-shaped structure including two opposing side walls. A first roller 3341 is rotatably mounted on each side wall of the first base plate 3351, with the central axis of the first roller 3341 being horizontally disposed, allowing the first roller 3341 to rotate vertically. A second base plate 3353 and a third base plate 3355 can be respectively fixed to the side walls of the first base plate 3351. The second roller 3343 is rotatably mounted on the second base plate 3353, with the central axis of the second roller 3343 being vertically disposed, allowing the second roller 3343 to rotate horizontally. A third roller 3345 is rotatably mounted on the third base plate 3355, with the central axis of the third roller 3345 being vertically disposed, allowing the third roller 3345 to rotate horizontally.

[0199] After the first tubular column assembly 130 is installed on the first pushing mechanism 335, the first roller 3341 of the first pushing mechanism 335 is used to adapt to the bottom wall of the plug-in plate 137 of the first tubular column assembly 130, and the second roller 3343 and the third roller 3345 are used to adapt to the side wall of the plug-in plate 137.

[0200] The first roller 3341 on the first base plate 3351, the second roller 3343 on the second base plate 3353, and the third roller 3345 on the third base plate 3355 cooperate to clamp the plug-in plate 137 of the first tubular column assembly 130. The first roller 3341 rolls against the bottom wall of the plug-in plate 137, while the second roller 3343 and the third roller 3345 roll against the side walls of the plug-in plate 137. The fourth driving cylinder 3350 pushes against the first tubular column assembly 130. Under the force of the fourth driving cylinder 3350, the first tubular column assembly 130 moves toward the first end of the tubular column body due to the rolling cooperation of the first roller 3341, the second roller 3343, and the third roller 3345, causing the plug-in plate 137 to be inserted into the first insertion slot of the tubular column body, and the first tubular column is embedded in the cavity of the tubular column body.

[0201] In order to adapt to first pipe column assemblies 130 of different sizes, optionally, the third roller 3345 on the third base plate 3355 can be set to an adjustable structure.

[0202] Specifically, please refer to FIG. 19 , which is a schematic structural diagram of the first pushing mechanism 335 from a second perspective.

[0203] The first pushing mechanism 335 may further include a fifth driving cylinder 3357 , which is fixed on the third base plate 3355 , and the third roller 3345 is rotatably disposed on a driving end of the fifth driving cylinder 3357 .

[0204] Optionally, the driving end of the fifth driving cylinder 3357 is fixedly connected to the mounting plate 3359 , and the third roller 3345 is rotatably mounted on the mounting plate 3359 .

[0205] Optionally, there may be multiple first rollers 3341, multiple second rollers 3343, and multiple third rollers 3345, with multiple first rollers 3341, multiple second rollers 3343, and multiple third rollers 3345 arranged in sequence. Rolling friction between the rollers and the plug-in board 137 reduces frictional resistance during axial movement of the plug-in board 137, facilitating sliding of the plug-in board 137 under the action of the fourth drive cylinder 3350.

[0206] Furthermore, in order to position the plug board 137 from the top, the plug board 137 is prevented from falling out from the top during the movement. Alternatively, please refer to FIG20 , which is a schematic structural diagram of the first pushing mechanism 335 from a third perspective.

[0207] Specifically, the first pushing mechanism 335 may further include a sixth driving cylinder 3346 , a connecting rod 3348 and a fourth roller 3349 .

[0208] The sixth drive cylinder 3346 is hingedly connected to the frame body 320. The first end of the connecting rod 3348 is hingedly connected to the driving end of the sixth drive cylinder 3346. The middle position of the connecting rod 3348 is hingedly connected to the frame body 320. The second end of the connecting rod 3348 is rotatably provided with a fourth roller 3349. The sixth drive cylinder 3346 drives the fourth roller 3349 to abut against or move away from the top wall of the plug board 137 via the connecting rod 3348.

[0209] When the sixth driving cylinder 3346 is extended, the first end of the connecting rod 3348 connected to the sixth driving cylinder 3346 rotates upward (counterclockwise from the perspective of Figure 20), and the second end of the fourth roller 3349 rotates downward (counterclockwise from the perspective of Figure 20), while driving the fourth roller 3349 to press against the top wall of the plug board 137, thereby limiting the position of the plug board 137 from the top.

[0210] When the sixth driving cylinder 3346 contracts, the first end of the connecting rod 3348 connected to the sixth driving cylinder 3346 rotates downward (clockwise from the perspective of Figure 20), and the second end of the fourth roller 3349 rotates upward (clockwise from the perspective of Figure 20), while driving the fourth roller 3349 away from the top wall of the plug-in board 137, thereby releasing the restriction on the plug-in board 137 from the top.

[0211] The first pushing mechanism 335 on the first workbench 330 pushes the first pipe column assembly 130 axially, and limits the bottom wall, side wall and top wall of the plug-in plate 137 respectively through the first roller 3341, the second roller 3343, the third roller 3345 and the fourth roller 3349, thereby ensuring that the first pipe column assembly 130 will not deflect during the axial movement, thereby ensuring smooth plug-in and correct plug-in position, which is conducive to improving the molding quality in the subsequent assembly process.

[0212] The second pushing mechanism of the second workbench is introduced in detail below.

[0213] 14 and 15 , further, the second pushing mechanism 355 is disposed on the second frame 351 , and the second frame 351 may further include a support frame 325 , which is fixedly connected to the frame body 320 , and the second pushing mechanism 355 is disposed on the support frame 325 .

[0214] After the second pipe string assembly 160 is initially fixed to the pipe string body 110, in order to prevent the second pipe string assembly 160 from interfering with the second pushing mechanism 355 during the rotation of the pipe string body 110, the second pushing mechanism 355 is escalably mounted on the support frame 325 of the second frame 351.

[0215] Please refer to FIG. 21 , which is a structural diagram showing the second pushing mechanism 355 disposed on the second frame 351 .

[0216] Specifically, the second pushing mechanism 355 may include a lifting mechanism 3551, a second driving cylinder 3555, and a third driving cylinder 3557. The lifting mechanism 3551 is movably mounted on the support frame 325. The second driving cylinder 3555 and the third driving cylinder 3557 are both mounted on the lifting mechanism 3551. The second driving cylinder 3555 is used to drive the second tubular column assembly 160 to move axially, and the third driving cylinder 3557 is used to position the second tubular column assembly 160.

[0217] Furthermore, the lifting mechanism 3551 may include a lifting cylinder 3552 and a lifting bracket 3554. The lifting cylinder 3552 is fixedly connected to the support frame 325, and the lifting bracket 3554 is fixedly connected to the driving end of the lifting cylinder 3552. A second driving cylinder 3555 and a third driving cylinder 3557 are both fixedly connected to the lifting bracket 3554. The lifting bracket 3554 may be a U-shaped structure. The second driving cylinder 3555 is fixedly connected to the bottom wall of the lifting bracket 3554 and is used to drive the second pipe string assembly 160 to move along the axial direction of the second pipe string assembly. The third driving cylinder 3557 is fixedly connected to the side wall of the lifting bracket 3554 and is used to drive the second pipe string assembly 160 to move in a direction perpendicular to the axial direction of the second pipe string assembly, thereby positioning the second pipe string assembly 160.

[0218] Optionally, a guide structure can be provided between the support frame 325 and the lifting frame 3554. For example, a guide hole can be provided on the support frame 325, and a guide column matching the guide hole can be provided on the lifting frame 3554. The guide column is passed through the guide hole and can move up and down with the lifting frame 3554 under the action of the lifting cylinder 3552.

[0219] In order to detect whether the second tubular column assembly 160 has moved into position along the axial direction of the tubular column body 110 under the action of the second driving cylinder 3555. Optionally, a through-beam sensor 3558 can be provided on the side of the lifting bracket 3554 close to the fixing bracket 322. When the second driving cylinder 3555 drives the second tubular column assembly 160 to move along its axial direction so that the second tubular column assembly 160 blocks the through-beam sensor 3558, the second driving cylinder 3555 stops driving, indicating that the second tubular column assembly 160 has moved into position. The through-beam sensor 3558 detects whether the second tubular column assembly 160 has moved into position along the axial direction of the tubular column body 110 under the action of the second driving cylinder 3555. The structure is simple, easy to install, and the detection is accurate.

[0220] In other optional embodiments, it is also possible to detect whether the second pipe column assembly 160 has moved into place in other ways. This application does not limit this, and the specific method depends on actual needs.

[0221] 14 , optionally, the first workbench 330 and the second workbench 350 are slidably disposed on the ground rail 310 , and a transmission mechanism (not shown) can be provided between the first workbench 330 and the ground rail 310 and between the second workbench 350 and the ground rail 310 . For example, a rack and pinion mechanism can be used for transmission.

[0222] Specifically, a rack can be provided on the ground rail 310. The first workbench 330 may further include a second motor and a second gear, both of which are disposed at the bottom of the first frame 331. The second motor is transmission-connected to the second gear, which meshes with the rack. Under the action of the second motor, the meshing of the second gear and the rack can drive the first frame 331 to slide relative to the ground rail 310. Similarly, the second workbench 350 may further include a third motor and a third gear. Both of the third motor and the third gear are disposed at the bottom of the second frame 351. The third motor is transmission-connected to the third gear, which meshes with the rack. Under the action of the third motor, the meshing of the third gear and the rack can drive the second frame 351 to slide relative to the ground rail 310.

[0223] The prefabricated tubular module molding apparatus 300 provided in this embodiment of the present application is rationally designed. The first and second workbenches 330, 350 can slide toward a central position along the ground rail 310, allowing the first and second clamping chuck mechanisms 333, 353 to cooperate and clamp and secure the tubular body 110. The first pushing mechanism 335 clamps the first tubular assembly 130 and drives it toward the tubular body 110 until the plug-in plate 137 of the first tubular assembly 130 is inserted into the first plug-in slot 113 at the first end of the tubular body 110. The second pushing mechanism 355 clamps the second tubular assembly 160 and drives it toward the tubular body 110 until the end of the second tubular assembly 160 corresponds to and abuts the second end of the tubular body 110, facilitating the pushing operation. The fixing assembly is first used to spot weld the connection between the tubular column body 110 and the plug-in plate 137, and then spot weld the connection between the tubular column body 110 and the second tubular column assembly 160, completing the preliminary fixation. Then, the first pushing mechanism 335 releases the first tubular column assembly 130, and the second pushing mechanism 355 releases the second tubular column assembly 160. The first pushing mechanism 335 and the second pushing mechanism 355 are respectively withdrawn. Finally, the fixing assembly cooperates with the first clamping chuck mechanism 333 and the second clamping chuck mechanism 353 to fully weld the connection between the tubular column body 110 and the first tubular column assembly 130 and the second tubular column assembly 160. This facilitates molding and can improve molding speed and assembly efficiency while ensuring molding quality. The use of the prefabricated tubular column module molding equipment 300 to prepare the above-mentioned prefabricated tubular column module 100 can achieve fully automated production.

[0224] In an embodiment of the present application, a pipe string forming method for preparing the above-mentioned prefabricated pipe string module 100 is also provided. The pipe string forming method prepares the prefabricated pipe string module 100 based on the above-mentioned prefabricated pipe string module forming device 300.

[0252] In this embodiment, for modular assembly building scenarios, multiple second ribs can be welded to a fixing plate, which can then be used to secure the multiple second ribs to the inner sidewall of the second pipe column. It is understood that in other optional scenarios, such as those with lower strength requirements, bolting, welding, riveting, bonding, and other methods can also be used for fixation. This application does not limit the application scenario or specific fixing method. The appropriate fixing method should be selected based on the specific application scenario.

[0260] The second tube column and the third tube column are both hollow columnar structures, a plurality of fixing grooves are provided on the side wall of the second tube column, and the third tube column may include a plurality of beams extending along the second preset direction.

[0261] Step S140 : embedding the third pipe column in the second pipe column so that the fixing groove corresponds to at least a portion of the crossbeam.

[0262] The third pipe column is embedded in the inner cavity of the second pipe column, and the position of the third pipe column relative to the second pipe column is adjusted so that the fixing groove of the second pipe column corresponds to at least part of the crossbeam of the third pipe column.

[0279] Step S304: fix the tubular body and the second tubular assembly at the target position.

[0280] The pipe column forming method provided in the embodiment of the present application, for the above-mentioned prefabricated pipe column module, first forms a first pipe column assembly and a second pipe column assembly, respectively; the formed first pipe column assembly is plugged into the first end of the pipe column body through a plug-in plate, and then the plug-in plate is fixed to the pipe column body; the formed second pipe column assembly is fixed to the second end of the pipe column body.

[0281] Optionally, the plug-in plate may be fixed to the pipe column body by welding, and the second pipe column assembly may be fixed to the second end of the pipe column body by welding.
