Specifically, the connecting assembly includes two upper and lower connecting modules, each of which is provided on the upper and lower boxes, and a calibration structure of the connecting assembly is installed on one of the connecting modules. After one box is hoisted onto the top of the other box, the calibration structure is used to calibrate the relative position of the other connecting module, thereby calibrating the position between the adjacent upper and lower boxes.

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clear, the following is a summary of the technical problems, technical solutions and beneficial effects to be solved by the present invention. Figures 1 to 6 It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0034] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0035] 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 quantity of the technical features being referred to. Features specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0036] References to "one embodiment," "some embodiments," or "an embodiment" in this specification mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in one or more embodiments of the present invention. The phrases "in one embodiment," "in some embodiments," "in other embodiments," "in yet other embodiments," etc., appearing in various places in this specification are not necessarily all referring to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically stated. Furthermore, in one or more embodiments, the particular features, structures, or characteristics may be combined in any suitable manner.

[0037] Conventional technology typically uses bolts, double-headed cones, or cross clips to connect the upper and lower adjacent boxes of a multi-story modular house. However, these connection methods lack sufficient rigidity and can only be used to connect multi-story modular houses with a short service life.

[0038] In the related art, to extend the service life of multi-story modular houses, upper and lower connecting modules are usually first installed on adjacent upper and lower boxes. When assembling the multi-story modular house, a connecting structure, such as steel bars or long tie rods, is then used to penetrate the upper and lower connecting modules between the two adjacent boxes. Finally, grouting material is poured between the connecting structure and each connecting module to form a mechanical bite. The grouting material is specifically concrete, which effectively connects the adjacent upper and lower boxes and provides the multi-story modular house with tensile and shear resistance. Among them, after one box is hoisted above another box, it is necessary to first use a calibration structure installed on the upper connecting module or the lower connecting module to calibrate the position between the two adjacent boxes. Then, the connecting structure is passed through the upper and lower connecting modules between the two adjacent boxes. Finally, grouting material is poured between the connecting structure and each connecting module. The above-mentioned multi-story modular house assembly process is complicated, resulting in low construction efficiency and is not conducive to the rapid installation of multi-story modular houses.

[0039] Based on this, embodiments of the present invention provide a connection assembly for a multi-story modular house. The two connection modules of the connection assembly can be connected to the first or second box of the multi-story modular house, respectively. The connector simultaneously performs the dual functions of aligning and connecting the two connection modules. This eliminates the need for separate, step-by-step installation of alignment and connection structures before grouting the grouting chamber. This provides the advantages of a simple assembly process and high construction efficiency. The connection assembly for a multi-story modular house of the present invention is described in detail below with reference to specific embodiments.

[0040] See also Figures 1 to 3 ,as well as Figure 6 ,in, Figure 1 This is a structural diagram of a multi-story modular house provided by an embodiment of the present invention. Figure 2 This is a front view structural diagram of a connection assembly provided by an embodiment of the present invention. Figure 3 A schematic diagram of a half-section structure of a connection assembly provided in one embodiment of the present invention. Figure 6 A schematic structural diagram of a connector provided in one embodiment of the present invention.

[0041] like Figures 1 to 3 ,as well as Figure 6 As shown, one embodiment of the present invention provides a connection assembly 1 for a multi-story modular house, which includes a first connection module 11, a second connection module 12, and a connector 13. The first connection module 11 is used to connect to the first box 2 of the multi-story modular house, and the second connection module 12 is used to connect to the second box 3 of the multi-story modular house. Furthermore, the connector 13 has a connecting portion 131, a shearing portion 132, and a calibration portion 133, which are connected in sequence. The connecting portion 131 is used to connect to the first connection module 11, and the calibration portion 133 is a columnar structure. The second connection module 12 is provided with a calibration hole 121 for the shearing portion 132 and the calibration portion 133 to fit through, as well as a grouting chamber 122 connected to the calibration hole 121. The shearing portion 132 is a tooth-like structure, which is used to engage with the grouting material poured into the grouting chamber 122.

[0042] Before the boxes of the multi-story modular house leave the factory, the first connecting module 11 of the connecting assembly 1 provided in this embodiment can be installed on the first box 2, and the second connecting module 12 can be installed on the second box 3. When assembling the multi-story modular house, the connecting portion 131 of the connecting member 13 is connected to the first connecting module 11. Thereafter, the first box 2 is hoisted above the second box 3, or the second box 3 is hoisted above the first box 2, so that the calibration portion 133 and the shearing portion 132 of the connecting member 13 are sequentially adapted to penetrate the calibration hole 121 located in the second connecting module 12, and penetrate into the grouting chamber 122 of the second connecting module 12, completing the calibration and positioning between the upper and lower boxes, and then pouring grouting material into the grouting chamber 122, so that the grouting material engages with the shearing portion 132 set as a tooth structure, thereby achieving an effective connection between the upper and lower boxes of the multi-story modular house and enabling the multi-story modular house to have tensile and shear resistance. Among them, the connecting piece 13 has the dual functions of calibration and connecting the adjacent upper and lower boxes. Before pouring grouting material into the grouting chamber 122, it is no longer necessary to install independent calibration structures and connection structures in steps, which can simplify the assembly process and improve construction efficiency.

[0043] It is understandable that the connection assembly 1 proposed in this embodiment is applicable to multi-story modular houses with two or more stories. For example, in a three-story modular house, a first connection module 11 can be set on the top of the first-story box, and a second connection module 12 can be set on the bottom of the second-story box. If the first connection module 11 is set on the top of the second-story box, the second connection module 12 is set on the bottom of the third-story box, and each adjacent first connection module 11 and second connection module 12 can be connected by a connector 13 and grouting material. In particular, when the third-story box is installed above the second-story box, grouting can be performed in the grouting chamber 122 between the first and second-story boxes. In the prior art, it is necessary to install all the multiple-story boxes first, then install the connection structure, and then grouting is performed in each grouting chamber 122. Therefore, the connection assembly 1 provided in this embodiment can effectively shorten the assembly period.

[0044] See also Figure 3 and Figure 6 In some specific embodiments, the connecting portion 131 of the connecting member 13 is provided with a thread, and the first connecting module 11 is welded with a nut 14. The connecting portion 131 of the connecting member 13 is used to be threadedly connected to the nut 14, thereby enabling the connection between the connecting member 13 and the first connecting module 11, which has the advantages of convenient connection and simple structure.

[0045] See also Figure 3 and Figure 6 In some specific embodiments, the connecting member 13 also has a sealing portion, which is arranged between the connecting portion 131 and the shear-resistant portion 132. The sealing portion is a rubber structure, and the sealing portion can be adapted to be connected with the calibration hole 121, thereby preventing the grouting material in the grouting chamber 122 from overflowing into the external space.

[0046] See also Figures 1 to 3 In another embodiment of the present invention, the connection assembly 1 includes a plurality of connecting members 13, and the plurality of connecting members 13 are connected to the first connection module 11 at intervals through their respective connecting portions 131. The second connection module 12 is provided with a plurality of calibration holes 121 at intervals, and the shear-resistant portion 132 and the calibration portion 133 of each connecting member 13 are respectively passed through each calibration hole 121.

[0047] In this embodiment, the first and second housings 2 and 3 are aligned and positioned using multiple connectors 13 and multiple alignment holes 121. This not only determines the installation position of the second housing 3 on the first housing 2, but also the installation angle between the second housing 3 and the first housing 2. Furthermore, multiple points of connection are formed between the upper and lower housings, thereby improving the connection stability between the upper and lower housings.

[0048] Specifically, the number of the connecting pieces 13 and the calibration holes 121 can be set to two, three, four or five, etc.

[0049] See also Figure 3 In another embodiment of the present invention, the second connecting module 12 is provided with a plurality of independent grouting chambers 122, each grouting chamber 122 is connected to each calibration hole 121 in a one-to-one correspondence, and the calibration portion 133 and the shear resistance portion 132 of each connecting member 13 can be inserted into each grouting chamber 122 from the corresponding calibration hole 121 one by one.

[0050] Compared with the integral single grouting chamber 122 , the present embodiment provides a plurality of mutually independent grouting chambers 122 , which can reduce the amount of grouting material, save materials, and reduce costs.

[0051] See also Figures 1 to 3 In another embodiment of the present invention, the second connection module 12 includes a plurality of connection blocks 123 arranged at intervals, a plurality of calibration holes 121 are arranged in each connection block 123 in a one-to-one correspondence, the connection block 123 is a hollow structure, and the internal cavities of the plurality of connection blocks 123 form a plurality of independent grouting chambers 122.

[0052] The second box body 3 with the first connecting module 11 and the connecting member 13 at the top is respectively connected to the first connecting module 11 at the top of the first box body 2. At this time, the shearing portion 132 and the calibration portion 133 of each connecting member 13 are facing upwards. Then, the second box body 3 with the first connecting module 11 and the connecting member 13 at the top is hoisted to the top of the first box body 2, so that the calibration portion 133 and the shearing portion 132 of each connecting member 13 pass through the calibration hole 121 on the corresponding connecting block 123 in turn and penetrate into the internal cavity of the corresponding connecting block 123. The upper and lower boxes can be precisely positioned by multiple connecting members 13 and multiple connecting blocks 123. Grouting material is then poured into each grouting chamber 122 to form a multi-point connection between the upper and lower boxes, thereby improving the connection stability of the upper and lower boxes. Alternatively, the connecting piece 13 can be arranged at the bottom of the first box body 2, and the connecting block 123 is correspondingly arranged at the top of the second box body 3, and the calibration hole 121 is arranged on the upward side of the connecting block 123. During assembly, the connecting parts 131 of each connecting piece 13 are respectively connected to the first connecting module 11 located at the bottom of the first box body 2. At this time, the shear-resistant part 132 and the calibration part 133 of each connecting piece 13 are both facing upward, and then the first box body 2 with the first connecting module 11 and the connecting piece 13 installed on the top is hoisted to the top of the second box body 3, so that the calibration part 133 and the shear-resistant part 132 of each connecting piece 13 pass through the calibration hole 121 on the corresponding connecting block 123 in turn, and penetrate into the internal cavity of the corresponding connecting block 123. Through multiple connecting pieces 13 and multiple connecting blocks 123, precise positioning between the upper and lower boxes can be achieved, and then grouting material is poured into each grouting chamber 122 to form a multi-point connection between the upper and lower boxes, thereby improving the connection stability of the upper and lower boxes.

[0053] Furthermore, if Figures 1 to 3 As shown, in this embodiment, the connection assembly 1 includes four connection members 13, each connection member 13 is correspondingly arranged at the four corners of the first box body 2, and the second connection module 12 includes four connection blocks 123, and each connection block 123 is correspondingly arranged at the four corners of the second box body 3.

[0054] The four connecting pieces 13 and the four connecting blocks 123 can achieve precise positioning between the upper and lower layers of the box, and can form multi-point connections between the upper and lower layers of the box, thereby improving the connection stability of the upper and lower layers of the box; in addition, each connecting block 123 is correspondingly arranged at the four corners of the box, so as to provide uniform support for the box.

[0055] See also Figures 1 to 3 In another embodiment of the present invention, a transverse support member 124 is connected between each two adjacent connection blocks 123.

[0056] In this embodiment, a transverse connector 13 is provided between every two connected connection blocks 123 so that each connection block 123 and each transverse connector 13 form an integral frame, thereby increasing the supporting force of the second connection module 12 on the box body.

[0057] See also Figures 1 to 3 In another embodiment of the present invention, the connection assembly 1 further includes an auxiliary connection member 15, a first end of the auxiliary connection member 15 is used to connect to the first connection module 11, and a second end of the auxiliary connection member 15 is used to connect to the second connection module 12.

[0058] In this embodiment, the first connecting module 11 and the second connecting module 12 can be connected by the auxiliary connecting member 15, thereby connecting the adjacent upper and lower boxes and enhancing the tensile strength between the adjacent upper and lower boxes. The multi-story modular house connected by the connecting assembly 1 provided in this embodiment not only has the ability to resist shear force, but also has a strong ability to resist tensile force, thereby being able to resist the horizontal force and overturning force generated by earthquakes and wind loads on the upper and lower boxes, and is suitable for areas prone to severe conditions such as earthquakes or extreme weather.

[0059] Furthermore, if Figures 1 to 3 As shown, in this embodiment, the auxiliary connecting member 15 is a connecting plate, a first end of which is connected to the first connecting module 11 via a bolt 16, and a second end of which is connected to the second connecting module 12 via a bolt 16. Specifically, the second end of the connecting plate is connected to the transverse support member 124 via a bolt 16. The bolt 16 can be a torsional shear high-strength bolt 16 or other high-strength bolt 16.

[0060] In this embodiment, the auxiliary connecting member 15 configured as a connecting plate is connected between the first connecting module 11 and the second connecting module 12 by bolts 16, thereby enabling the adjacent upper and lower layers of the box to have tensile strength, and the connection using bolts 16 has the advantages of convenient connection and simple structure.

[0061] Furthermore, if Figures 1 to 3 As shown, in this embodiment, the connection assembly 1 includes four pairs of connection plates, and a pair of connection plates is provided between each transverse support member 124 and the first connection module 11, and each pair of connection plates is spaced at both ends of the transverse support member 124, which can stably connect the upper and lower layers of the box.

[0062] Furthermore, if Figures 1 to 3As shown, in this embodiment, the connecting plate is a triangular plate. One end of the triangular plate, i.e., one vertex, can be connected to the transverse support member 124 via a bolt 16, while the other two ends, i.e., the other two vertices, are correspondingly connected to the first connecting module 11 via bolts 16. Alternatively, one end of the triangular plate can be connected to the first connecting module 11 via a bolt 16, while the other two ends are correspondingly connected to the transverse support member 124 via bolts 16.

[0063] Preferably, if Figures 1 to 3 As shown, in this embodiment, a pair of triangular plates provided at both ends of each transverse support member 124 are provided in opposite directions, which can prevent the upper and lower layers of the box from being eccentric and avoid affecting the connection stability of the upper and lower layers of the box.

[0064] Specifically, the connecting plate may also be a square plate, a circular plate or other irregularly shaped plates.

[0065] Furthermore, the connecting plate is set to a metal plate, such as a steel plate or an iron plate. The connecting plate made of metal material has good durability and stable properties. The use of metal plates can effectively ensure the connection reliability and life of the modular house.

[0066] Please also refer to Figure 4 ,in, Figure 4 for Figure 2 Schematic diagram of the cross-sectional structure of AA.

[0067] like Figures 1 to 4 As shown, in another embodiment of the present invention, a mounting hole 17 is provided on the side of the transverse support member 124 facing the second box body 3 and a side of the first connecting module 11 facing the first box body 2, respectively. A first through hole 18 is provided on the side of the transverse support member 124 facing away from the second box body 3 and a side of the first connecting module 11 facing away from the first box body 2, respectively. The axis of the mounting hole 17 coincides with the axis of the first through hole 18, and the connecting plate is provided with a plurality of second through holes 151.

[0068] In this embodiment, before the box is shipped from the factory, the mounting holes 17 and the first through holes 18 are first opened on the transverse support member 124, and the mounting holes 17 and the first through holes 18 are opened on the first connecting module 11. Then, a plurality of bolts 16 are passed through the transverse support member 124 and the first connecting module 11 through the mounting holes 17, and the threaded portion of each bolt 16 is passed through the corresponding first through hole 18. Finally, the side of the transverse support member 124 provided with the mounting holes 17 is connected to the second box body 3, and the side of the first connecting module 11 provided with the mounting holes 17 is connected to the first box body 2. Thereafter, the box is shipped from the factory and transported to the assembly site. When assembling the upper and lower layers of the box, the auxiliary connecting member 15 provided as a connecting plate is provided between the transverse support member 124 and the first connecting module 11, and the threaded portion of each bolt 16 is passed through the corresponding second through holes 151 on the connecting plate. Thereafter, the nut 14 of each bolt 16 is connected to the respective threaded portion, thereby achieving the connection between the transverse support member 124 and the first connecting module 11.

[0069] If the mounting holes 17 and first through-holes 18 are drilled at the assembly site after the box leaves the factory to install the bolts 16, holes would also need to be drilled in the side walls of the box to facilitate the insertion of the bolts 16. This would damage the walls of the box. However, in this embodiment, the bolts 16 are pre-installed in the transverse support members 124 and the first connecting module 11 before the box leaves the factory. This eliminates the need to drill the mounting holes 17, first through-holes 18, and holes in the side walls of the box at the assembly site, thereby ensuring optimal performance of the box.

[0070] See also Figures 1 to 3 In another embodiment of the present invention, the second connection module 12 is further provided with a grouting hole 125 , which is communicated with the grouting chamber 122 , so that grouting material can be poured into the grouting chamber 122 from the outside.

[0071] Furthermore, if Figures 1 to 3 As shown, in this embodiment, each connecting block 123 is respectively connected to a vertical support member 126, the vertical support member 126 is perpendicular to the horizontal support member 124, the vertical support member 126 is a hollow structure, and the side wall of each vertical support member 126 is provided with a grouting hole 125 connected to its internal cavity, and a channel 19 for grouting material to pass through is formed between the surfaces where each connecting block 123 and the corresponding vertical support member 126 are interconnected.

[0072] In actual situations, grouting material is poured from the grouting hole 125 provided on the side wall of the vertical support member 126. Under the action of gravity, the grouting material can flow into the grouting chamber 122 through the internal cavity of the vertical support member 126 and the channel 19 between the connecting block 123 and the vertical support member 126, which has the advantage of convenient filling.

[0073] Furthermore, if Figures 1 to 3As shown, in this embodiment, each grouting hole 125 is correspondingly arranged on the side of each vertical support member 126 facing the external space, which is convenient for grouting on the outside of the box. The operation is simple and convenient. Compared with the grouting holes 125 being correspondingly arranged on the side of each vertical support member 126 facing the internal space of the box, damage to the decorated wall or wall material of the box can be avoided.

[0074] Furthermore, if Figures 1 to 3 As shown, in this embodiment, each vertical support member 126 is provided with an overflow hole 127, and each overflow hole 127 is provided below the corresponding grouting hole 125.

[0078] If the first connecting module 11 is connected to the bottom of the second box 3, the connecting piece 13 needs to be installed at the bottom of the second box 3. When installing the connecting piece 13, the second box 3 needs to be lifted first, and then the connecting piece 13 is installed. However, the assembler is assembling under the lifted second box 3, which poses a certain safety hazard. Therefore, it is preferred to install the first connecting module 11 and the connecting piece 13 at the top of the first box 2 to facilitate installation and reduce the probability of safety accidents.

[0079] See also Figure 1 and Figure 2 In another embodiment of the present invention, a multi-story modular house includes a plurality of first boxes 2 arranged side by side, and a plurality of second boxes 3 arranged side by side, wherein the plurality of second boxes 3 are arranged one by one on top of the plurality of first boxes 2, and adjacent first boxes 2 and second boxes 3 are connected by a connecting assembly 1.

[0080] In actual situations, it can be flexibly designed according to actual living needs, so that multiple first boxes 2 and multiple second boxes 3 can be assembled, which has the advantage of strong functionality.

[0081] See also Figures 1 to 3 In another embodiment of the present invention, the multi-story modular house further includes a fixing member 4 , and the two adjacent first boxes 2 and the two adjacent second boxes 3 are connected by the fixing member 4 .

[0082] In this embodiment, the two adjacent boxes on the left and right can be connected by the fixing member 4, so that the boxes are connected and form an integral structure, thereby improving the overall performance of the multi-story modular house, so that the multi-story modular house in this embodiment can be used in areas prone to severe conditions such as earthquakes or extreme weather.

[0083] Furthermore, if Figures 1 to 3 As shown, in this embodiment, the fixing member 4 can be a connecting plate with the same structure as the auxiliary connecting member 15, the two adjacent first boxes 2 are connected by a pair of connecting plates, and the two adjacent second boxes 3 are also connected by a pair of connecting plates, and the connecting plates are arranged at intervals in the vertical direction, so that an integral structure can be formed between the four adjacent boxes.

[0084] Furthermore, if Figures 1 to 3 As shown, in this embodiment, the connecting plates are triangular plates, and the two adjacent triangular plates are arranged in opposite directions, which can prevent the left and right boxes from being eccentric and avoid affecting the connection stability of the left and right boxes.

[0085] Please also refer to Figure 5 ,in, Figure 5 for Figure 3 A partial enlarged view of point B in the middle.

[0086] like Figure 1 、 Figure 3 and Figure 5 As shown, in another embodiment of the present invention, the multi-story modular house includes a plurality of first boxes 2 arranged side by side, and a plurality of second boxes 3 arranged side by side. The multi-story modular house also includes a first pad 5 and a second pad 6. The first box 2 is located at the outermost corners of the top of the multi-story modular house and is respectively provided with a first pad 5. The first pad 5 is specifically arranged between the first connecting module 11 at the top of the first box 2 and the connecting block 123 at the bottom of the second box 3, and the first pad 5 is provided with a third through hole 7 for the connecting member 13 to pass through; two second pads 6 are provided at the four corners where the two adjacent first boxes 2 are abutted, and the second pad 6 is horizontally arranged on the top of the two adjacent first boxes 2. The second pad 6 is specifically arranged between the first connecting module 11 at the top of the first box 2 and the connecting block 123 at the bottom of the second box 3, and the second pad 6 is provided with two third through holes 7 for the connecting member 13 to pass through.

[0087] In practice, if the first connecting modules 11 and the second connecting modules 12 of the upper and lower boxes were to be directly contacted for support, the surface accuracy of the first connecting modules 11 and the second connecting modules 12 would need to be precisely controlled to ensure that the upper and lower boxes do not tilt or fall, which would significantly increase manufacturing costs. In this embodiment, however, first and second pads 5 and 6 are provided on top of each first box 2 to provide isolation and support for each second box 3. During production, it is sufficient to improve the surface accuracy of the first and second pads 5 and 6, thereby reducing manufacturing costs.

[0088] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
