Description

Technical Field

[0001] This utility model relates to the field of mobile prefabricated housing technology, specifically a column assembly mechanism for mobile prefabricated housing. Background Technology

[0002] Mobile prefabricated houses, also known as mobile homes, can be easily and quickly assembled and disassembled. The installation process includes container hoisting, container connection, and door and window installation. Mobile prefabricated houses are mainly composed of frame structure, wall structure, roof structure, door and window structure, and floor structure. They are modular buildings assembled with steel frame as the main body and lightweight cladding panels. The main frame uses steel profiles, such as channel steel, I-beams, square tubes, etc., which are welded or bolted together to form the container skeleton. They can be prefabricated in the factory and assembled on site without complicated construction. Multiple containers can be quickly spliced ​​together with bolts or clips to flexibly combine into single-story, multi-story, or irregular-shaped buildings.

[0003] Chinese Patent Publication No. CN116752646A discloses a multi-layer folding container house, in which the support column and the top plate are connected by a connector, and the connector is fixed by a fixing bolt, thereby achieving stable support for the top plate;

[0004] In actual on-site assembly, if the multi-bolt connection of the connectors, top plate and support columns is not operated according to the principle of diagonal symmetry and step-by-step tightening, it will lead to uneven stress on the connectors, warping deformation, further aggravating sealing failure and structural instability. Moreover, if the preload of the multi-bolts is too large, exceeding the yield strength of the bolt material, it may cause bolt tensile deformation and thread stripping. If the preload is insufficient, gaps will exist between the connectors, and the bolts will bear additional shear force when under stress, accelerating loosening. Therefore, a column assembly mechanism for mobile prefabricated houses is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a column assembly mechanism for mobile prefabricated houses. It offers advantages such as stable assembly and uniform stress distribution. This solves the problem that in actual on-site assembly, if the multi-bolt connections between the connectors, top plate, and support columns are not tightened according to the principle of diagonal symmetry and step-by-step tightening, uneven stress on the connectors can lead to warping and deformation, further exacerbating sealing failure and structural instability. Furthermore, if the preload of the multiple bolts is too high, exceeding the yield strength of the bolt material, it may cause bolt tensile deformation and thread stripping. Insufficient preload results in gaps between the connectors, causing the bolts to bear additional shear force under stress, accelerating loosening.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a column assembly mechanism for mobile prefabricated houses, comprising a sleeve component installed on the mobile prefabricated house, wherein the sleeve component is provided with an insertion component for connecting square columns, the sleeve component is provided with a fixing component for fixing the insertion component, and the sleeve component is provided with a locking component for locking the fixing component.

[0007] The socket component includes a socket base, a boss is fixedly installed inside the socket base, and two symmetrically distributed mating grooves are opened inside the socket base.

[0008] The plug-in component includes two rectangular frames installed on the outer surface of the square column. Each of the two rectangular frames has a plug-in plate that extends through one end to the outside of the square column. Each of the two plug-in plates has a slot on one side of its opposite side.

[0009] The fixing component includes two embedded frames disposed inside the socket base. Fixing blocks are fixedly installed on opposite sides of the two embedded frames, and the two fixing blocks are adapted to the two slots. Right-angled trapezoidal slots are opened on opposite sides of the two embedded frames, and the right-angled trapezoidal slots on the same side are aligned with the mating slots on the same side.

[0010] Furthermore, the fixing component includes a sealing cover plate, which is adapted to the sleeve base. The sealing cover plate is provided with two extrusion plates, and the extrusion plates on the same side are adapted to the mating groove on the same side. Both extrusion plates are provided with inclined surfaces, and the inclined surfaces on the same side are coplanar with the trapezoidal surfaces of the right-angled trapezoidal groove on the same side.

[0011] Furthermore, a top plate is fixedly connected to the outer surface of the socket base, and a square post penetrating into the interior of the socket base is provided at the bottom of the top plate.

[0012] Furthermore, two symmetrically distributed rectangular slots are provided on the square column, and the end of the plug-in plate passes through the rectangular slot and extends into the interior of the square column, while the head of the plug-in plate passes through and extends into the exterior of the square column.

[0013] Furthermore, both the fixing block and the sealing cover plate are provided with several threaded holes for installing bolts, and the outer surface of the sleeve base is fitted with a rubber cap.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] This column assembly mechanism for mobile prefabricated houses features a socket component, a fixing component, and a plug-in component. The plug-in plate and the mating groove work together to precisely position the square column and the socket component. The fixing block engages with the groove to form a preliminary mechanical lock, preventing axial or radial displacement of the square column. The wedge-tightening structure is formed by the inclined surface of the pressing plate and the right-angled trapezoidal groove in the locking component. The lateral force of the inclined surface pushes the inner frame to move, continuously increasing the contact pressure between the fixing block and the groove, achieving a gapless connection. Fixing is completed in three steps: plugging, clamping, and locking. This avoids the complex operation of multiple bolts requiring diagonal symmetry and step-by-step tightening, and eliminates the need for multiple bolt connections, solving the problem of deformation or loosening caused by improper preload.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1: Please refer to Figure 1-5In this embodiment, a column assembly mechanism for a mobile prefabricated house includes a sleeve component 1 installed on the mobile prefabricated house. The sleeve component 1 has an insertion component 2 for connecting the square column inside, a fixing component 3 for fixing the insertion component 2 inside, and a locking component 4 for locking the fixing component 3 on the sleeve component 1.

[0024] Example 2: Please refer to Figure 1-5 Based on Embodiment 1, the socket component 1 includes a socket base 11, a boss 12 is fixedly installed inside the socket base 11, and two symmetrically distributed mating grooves 13 are opened inside the socket base 11.

[0025] The plug-in component 2 includes two rectangular frames 21 installed on the outer surface of the square column 5. Each of the two rectangular frames 21 has a plug-in plate 22 that extends through one end to the outside of the square column 5. Each of the two plug-in plates 22 has a slot 23 on one side of its opposite side.

[0026] The fixing component 3 includes two embedded frames 31 set inside the socket base 11. Fixing blocks 32 are fixedly installed on opposite sides of the two embedded frames 31. The square column 5 and the socket component 1 are accurately positioned by the cooperation of the plug plate 22 and the docking groove 13. The fixing blocks 32 are inserted into the groove 23 to form a preliminary mechanical lock to prevent the square column 5 from shifting axially or radially. The two fixing blocks 32 are adapted to the two grooves 23. Right-angled trapezoidal grooves 33 are opened on opposite sides of the two embedded frames 31, and the right-angled trapezoidal grooves 33 on the same side are aligned with the docking grooves 13 on the same side.

[0027] The outer surface of the socket base 11 is fixedly connected to the top plate 6. The bottom of the top plate 6 is provided with a square column 5 that penetrates into the interior of the socket base 11. The top plate 6 and the socket base 11 can be pre-welded together to facilitate the subsequent assembly of the mobile prefabricated house.

[0028] In addition, two symmetrically distributed rectangular slots are provided on the square column 5, and the end of the plug plate 22 passes through the rectangular slot and extends into the interior of the square column 5, while the head of the plug plate 22 passes through and extends into the exterior of the square column 5. The two rectangular frames 21 are symmetrically fixed on the outer surface of the square column 5, so that the plug plate 22 passes through the pre-set rectangular slot of the square column 5, and its head extends into the exterior of the square column 5. The slots 23 of the two plug plates 22 face each other, reserving space for subsequent cooperation with the fixing block 32.

[0029] Using the above technical solution, two rectangular frames 21 are symmetrically fixed on the outer surface of the square column 5, so that the plug-in plate 22 passes through the pre-set rectangular groove of the square column 5, with its head extending to the outside of the square column 5, and the grooves 23 of the two plug-in plates 22 face each other, reserving space for subsequent cooperation with the fixing block 32. The square column 5 with the plug-in component 2 assembled is vertically placed into the socket base 11, so that the bottom of the square column 5 contacts the boss 12, and at the same time, it is ensured that the head of the plug-in plate 22 is accurately inserted into the socket base 11 to complete the initial positioning. The two embedded frames 31 are placed inside the socket base 11, so that the fixing block 32 on the embedded frame 31 is aligned with the groove 23 of the plug-in plate 22. At this time, the right-angled trapezoidal groove 33 of the embedded frame 31 is aligned with the docking groove 13 of the socket base 11, realizing the initial fixation of the square column 5 and the socket component 1.

[0030] Example 3: Please refer to Figure 1-5 Based on Embodiment 2, the fixing component 3 includes a sealing cover plate 41, which is adapted to the sleeve base 11. Two pressing plates 42 are provided on the sealing cover plate 41, and the pressing plates 42 on the same side are adapted to the mating groove 13 on the same side. Both pressing plates 42 are provided with inclined surfaces 43, and the inclined surfaces 43 on the same side are coplanar with the trapezoidal surfaces of the right-angled trapezoidal groove 33 on the same side. When locked, the inclined surfaces 43 of the pressing plates 42 and the right-angled trapezoidal groove 33 of the inner frame 31 form a wedge-tight structure. The lateral component force of the inclined surfaces 43 pushes the inner frame 31 to move inward, so that the contact pressure between the fixing block 32 and the groove 23 continuously increases, achieving a gapless connection.

[0031] The fixing block 32 and the sealing cover plate 41 are provided with several threaded holes for installing bolts. The outer surface of the sleeve base 11 is fitted with a rubber cap 14. Bolts are installed through the threaded holes on the sealing cover plate 41, so that the bolts connect the sealing cover plate 41 and the fixing block 32, thereby realizing the locking of the square column 5 by using the plug plate 22, the fixing block 32, the inner frame 31 and the extrusion plate 42.

[0032] Using the above technical solution, the sealing cover plate 41 is covered, and the extrusion plate 42 on the sealing cover plate 41 is inserted along the mating groove 13. The inclined surface 43 of the extrusion plate 42 fits against the trapezoidal surface of the right-angled trapezoidal groove 33 of the inner frame 31. Then, the sealing cover plate 41 is pressed. At this time, the extrusion plate 42 presses the inner frame 31 inward through the inclined surface 43, forcing the fixing block 32 to more tightly clamp the groove 23 until the two fixing blocks 32 abut against each other and are embedded in the groove 23, while the extrusion plate 42 abuts against the boss 12. The bolt is installed through the threaded hole on the sealing cover plate 41, so that the bolt connects the sealing cover plate 41 and the fixing block 32, thereby realizing the locking of the square column 5 by using the plug plate 22, the fixing block 32, the inner frame 31 and the extrusion plate 42. After assembly, a rubber cap 14 can be put on the outer surface of the sleeve base 11 to improve the sealing and protection performance.

[0033] The working principle of the above embodiments is as follows:

[0034] When using the column assembly mechanism for mobile prefabricated houses, two rectangular frames 21 are symmetrically fixed on the outer surface of the square column 5, so that the plug plate 22 passes through the pre-set rectangular groove of the square column 5, and its head extends to the outside of the square column 5. The grooves 23 of the two plug plates 22 face each other, leaving space for subsequent cooperation with the fixing block 32.

[0035] Place the assembled plug-in component 2 into the socket base 11 vertically, so that the bottom of the plug-in component 5 contacts the boss 12, and at the same time ensure that the first end of the plug-in plate 22 is accurately inserted into the socket base 11 to complete the initial positioning.

[0036] Place the two inner frames 31 inside the socket base 11, so that the fixing block 32 on the inner frame 31 is aligned with the slot 23 of the plug plate 22. At this time, the right-angled trapezoidal slot 33 of the inner frame 31 is aligned with the docking slot 13 of the socket base 11, thus achieving the initial fixation of the square column 5 and the socket component 1.

[0037] Cover the sealing cover plate 41, and insert the extrusion plate 42 on the sealing cover plate 41 along the mating groove 13. The inclined surface 43 of the extrusion plate 42 fits against the trapezoidal surface of the right-angled trapezoidal groove 33 of the inner frame 31. Then press the sealing cover plate 41. At this time, the extrusion plate 42 presses the inner frame 31 inward through the inclined surface 43, forcing the fixing block 32 to clamp the groove 23 more tightly until the two fixing blocks 32 abut against each other and are embedded in the groove 23, while the extrusion plate 42 abuts against the boss 12. Install bolts through the threaded holes on the sealing cover plate 41, so that the bolts connect the sealing cover plate 41 and the fixing block 32, thereby realizing the locking of the square column 5 by using the plug plate 22, the fixing block 32, the inner frame 31 and the extrusion plate 42. After assembly, a rubber cap 14 can be put on the outer surface of the socket base 11 to improve the sealing and protection performance.
