The second frame body 105' in one module unit is stacked above the first connecting piece 104' in another module unit to form the modular building.

[0054] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0055] The embodiments of the utility model will be described below in combination with Figures 4 to 7 .

[0056] According to the embodiments of the utility model, a kind of modular building is provided, comprising:

[0057] Multiple module units 1 are stacked along the height direction or horizontal direction, each module unit 1 includes first cavity structure, one end of module unit 1 is equipped with first protrusion, and the other end is equipped with first groove 101, first protrusion is arranged in the direction away from first groove 101, and first protrusion includes second cavity structure, and second cavity structure is communicated with first cavity structure;

[0058] In adjacent module units 1, the first protrusion of one module unit 1 is arranged in the first groove 101 of another module unit 1.

[0059] In the modular building of the embodiment, by providing the first protrusion at one end of the module unit 1, when the module unit 1 is stacked in the height direction, the size of the module unit 1 in the height direction can be increased, so that the part of the height can be utilized, thereby increasing the net height of the module unit 1, and when the module unit 1 is stacked in the horizontal direction, the size of the module unit 1 in the horizontal direction can be increased, so that the part of the space can be utilized, thereby increasing the net utilization space of the module unit 1, and further achieving the technical effect of improving the comfort of residential use. At the same time, by providing the first recess 101 at the other end of the module unit 1, the first protrusion can be arranged inside the first recess 101 to realize the positioning and fixing of the adjacent module unit 1, without additionally increasing the connecting gap between the adjacent module units 1. Based on this, not only the increase of the net utilization space of the module unit 1 can be realized without increasing the overall height or width of the modular building, but also by the cooperation between the first protrusion and the first recess 101, the connecting gap between the adjacent module units 1 can be reduced, further reducing the waste of the internal space of the module unit 1, so as to achieve the technical effect of improving the net utilization space of the module unit 1. At the same time, by the cooperation between the first protrusion and the first recess 101, the positioning accuracy of the adjacent module units 1 can also be improved, so as to achieve the technical effect of improving the installation accuracy of the modular building.

[0060] At the same time, by the installation between the first protrusion and the first recess 101, the number of connecting points between the adjacent module units 1 can be increased, the lateral force resistance of the adjacent module units 1 can be improved, and the sliding, instability or even collapse of the modular building under external force can be avoided, so as to achieve the technical effects of improving the connection stability between the adjacent module units 1, further improving the safety redundancy of the modular building, and improving the robustness of the modular building.

[0061] In the embodiment, the plurality of module units 1 are stacked in the height direction. As a convertible embodiment, the plurality of module units 1 can also be stacked in the horizontal direction.

[0062] In addition, in combination with Figure 6 It is shown that, in the embodiment, the first protrusion comprises:

[0063] At least two side walls 10311;

[0064] A first connecting piece 104 is fixedly connected between the side walls 10311, the first connecting piece 104 and the side walls 10311 jointly surround to form a second cavity structure, and the thickness of the first connecting piece 104 is greater than the thickness of the side walls 10311, that is, the size of the first connecting piece 104 in the vertical direction shown is greater than the size of the side walls 10311 in the horizontal direction shown. Figure 6 Figure 6 In the embodiment, the side walls 10311 are arranged in the horizontal direction shown.

[0065] In the embodiment, the side walls 10311 are arranged in the horizontal direction shown.​Figure 5 There are two along the X-axis direction shown. Figure 5 Of course, in other embodiments, the number of side walls 10311 can be adjusted according to the shape of the module unit 1, for example, only two side walls 10311 are provided along the X direction.

[0066] Meanwhile, in other embodiments, the thickness of the first connector 104 may also be equal to the thickness of the side wall 10311. Compared with other embodiments, in this embodiment, by limiting the thickness of the first connector 104 to be greater than the thickness of the side wall 10311, the influence of the first protrusion on the internal space of the module unit 1 can be reduced, for example, the thickness of the first connector 104 may be reduced. Figure 5 The influence of the space usage of the module unit 1 in the X-axis direction can achieve the technical effect of reducing the influence on the internal space of the module unit 1 while increasing the internal height of the module unit 1.

[0067] Preferably, the side wall 10311 is provided separately from the first connector 104. Based on this, the thickness of the side wall 10311 can be easily adjusted, so that the required thickness of the side wall 10311 can be set as needed, thereby reducing the impact of the first protrusion on the use of the internal space of the module unit 1.

[0068] At the same time, by limiting the materials of sidewall 10311 and first connector 104 to different materials, even if the thickness of sidewall 10311 is reduced, a stable connection with first connector 104 can be formed, thereby achieving the technical effect of ensuring the safety of module unit 1. Specifically, sidewall 10311 can be an "L"-shaped angle steel, and first connector 104 is a rectangular top plate made of conventional materials. First connector 104 is provided with angle steel on all four sides.

[0069] In other embodiments, the side wall 10311 may also be an L-shaped steel plate, and the first connector 104 may be placed on the steel plate. Of course, in other embodiments, depending on the design of the module unit 1, only the side wall 10311 and the first connector 104 may be provided separately, or only the side wall 10311 and the first connector 104 may be made of different materials.

[0070] In addition, in this embodiment, the module unit 1 includes:

[0071] a first frame, wherein a first protrusion is provided on the first frame;

[0072] The second frame is spaced apart from the first frame, a first cavity structure is formed between the first frame and the second frame, and a first groove 101 is provided on the second frame;

[0073] The support structure 102 is fixedly connected to the first frame at one end and fixedly connected to the second frame at the other end. The support structure 102 is in the shape of a column.

[0074] The first frame, the second frame and the support structure 102 are used to build the module unit 1, and the installation and fixation between the first frame, the second frame and the support structure 102 can be realized in the factory. Therefore, at the construction site of the modular building, the modular building can be built by assembling a plurality of module units 1, the construction period of the modular building can be shortened, and the technical effect of improving the construction simplicity of the modular building is achieved.

[0075] Further, in the embodiment, the first frame, the second frame and the support structure 102 are used to build the module unit 1, and the installation and fixation between the first frame, the second frame and the support structure 102 can be realized in the factory. Therefore, at the construction site of the modular building, the modular building can be built by assembling a plurality of module units 1, the construction period of the modular building can be shortened, and the technical effect of improving the construction simplicity of the modular building is achieved. Figure 7 As shown in FIG. 1 and FIG. 2, one end of the support structure 102 is provided with a second protrusion 1021, and the other end of the support structure 102 is provided with a second groove 1022.

[0076] In adjacent module units 1, the second protrusion 1021 of one module unit 1 is arranged in the second groove 1022 of the other module unit 1.

[0077] The second protrusion 1021 and the second groove 1022 are arranged on the support structure 102, so that the second protrusion 1021 of one module unit 1 is fixedly installed in the second groove 1022 of the other module unit 1 in adjacent module units 1. The positioning points of adjacent module units 1 can be increased, so as to improve the accuracy and simplicity of the positioning of adjacent module units 1.

[0078] Of course, in other embodiments, a connecting hole can also be arranged at both ends of the support structure 102, and a positioning pin can be inserted into the connecting holes of the two support structures 102 in adjacent module units 1 to realize the positioning of the two support structures 102 in adjacent module units 1 along the height direction. Compared with other embodiments, the positioning is realized by the second protrusion 1021 and the second groove 1022 in the embodiment, which can not only increase the positioning area between adjacent module units 1, but also improve the stability of the connection between adjacent support structures, thereby improving the safety of the modular building.

[0079] In addition, in combination with Figure 4 and Figure 5 In the embodiment, the first frame includes:

[0080] The first frame body 103 includes a first hollow cavity;

[0081] The first protrusion is arranged in the first hollow cavity, and the first connecting piece 104 protrudes from the first hollow cavity.

[0082] The first protrusion is the top plate of the module unit 1, so that the first protrusion can also serve as part of the first frame, thus eliminating the need to additionally provide a top plate for the module unit 1, reducing the parts required for the first frame, thereby achieving the technical effect of improving the convenience of setting the module unit 1.

[0083] Specifically, the side wall 10311 is fixed to the inner side of the first frame body 103, the bottom surface of the first frame body 103 and the bottom surface of the side wall 10311 are located on the same horizontal line, the top surface of the side wall 10311 extends upward, the height of the top surface of the side wall 10311 is higher than the height of the top surface of the first frame body 103, and is connected and fixed with the first connecting piece 104, forming the connection and fixation of the first protrusion and the first frame body 103. Figure 6

[0084] Further, the first frame comprises:

[0085] An adjusting structure (not shown in the figure) is arranged between the first frame body 103 and at least one side wall 10311 of the first protrusion, for adjusting the distance between the first frame body 103 and the first protrusion.

[0086] By providing the adjusting structure, it can be avoided that the machining error exists between the two adjacent module units 1 during the machining process, causing the position of the first protrusion in one module unit 1 to be unable to match the position of the first groove 101 in another module unit 1, and the adjusting structure can adjust the position of the first protrusion, that is, to ensure that the adjacent module units 1 can be installed and fixed, so as to achieve the technical effect of improving the positioning accuracy between the first protrusion of one module unit 1 and the first groove 101 of another module unit 1.

[0087] Specifically, the first frame body 103 and the two side walls 10311 in the X direction of the first protrusion in the embodiment are both provided with adjusting structures. As a convertible embodiment, the first frame body 103 can be provided with an adjusting structure only between the first protrusion and one side wall 10311 in the X direction.

[0088] In the embodiment, the adjusting structure can be a pad, which is installed between the first frame body 103 and the side wall 10311, so as to ensure that the first protrusion in one module unit 1 can be installed and fixed with the first groove 101 of another module unit 1, eliminating the defect that the machining error causes the installation to be impossible, thereby achieving the technical effect of improving the accuracy of the installation of the adjacent module units 1.

[0089] ​Preferably, the adjusting structure is a telescopic structure. By adjusting the telescopic length of the adjusting structure, the position of the first protrusion can be adjusted, thereby achieving the technical effect of improving the convenience of adjusting the position of the first protrusion.

[0090] Specifically, the adjusting structure can be a telescopic spacer. Based on this, the design error of the module unit 1 can be avoided, so that the position of the first protrusion in one module unit 1 interferes with the position of the first groove 101 in another module unit 1, and the first protrusion in one module unit 1 cannot be installed in the first groove 101 of another module unit 1. Figure 5 For example, in the X-axis direction, when the left side of the first protrusion in one module unit 1 interferes with the left side of the first groove 101 in another module unit 1, the position of the left side of the first protrusion in the module unit 1 is adjusted by stretching the adjusting structure, and the right side of the first protrusion is moved towards the right side of the first protrusion. At this time, the adjusting structure corresponding to the right side of the first protrusion is compressed, and the first protrusion moves in the X-axis direction, thereby eliminating the interference between the position of the first protrusion in one module unit 1 and the position of the first groove 101 in another module unit 1. The first protrusion in one module unit 1 can be assembled with the first groove 101 in another module unit 1, thereby achieving the technical effect of improving the convenience of installing the first protrusion and the first groove 101. As a convertible embodiment, the adjusting structure can also be a plurality of spacers with different lengths. Figure 5 For example, in the X-axis direction, when the left side of the first protrusion in one module unit 1 interferes with the left side of the first groove 101 in another module unit 1, the position of the left side of the first protrusion in the module unit 1 is adjusted by stretching the adjusting structure, and the right side of the first protrusion is moved towards the right side of the first protrusion. At this time, the adjusting structure corresponding to the right side of the first protrusion is compressed, and the first protrusion moves in the X-axis direction, thereby eliminating the interference between the position of the first protrusion in one module unit 1 and the position of the first groove 101 in another module unit 1. The first protrusion in one module unit 1 can be assembled with the first groove 101 in another module unit 1, thereby achieving the technical effect of improving the convenience of installing the first protrusion and the first groove 101. As a convertible embodiment, the adjusting structure can also be a plurality of spacers with different lengths.

[0091] Of course, in other embodiments, the telescopic structure can also be an electric push rod, which can also achieve the technical effect of improving the convenience of adjusting the position of the first protrusion.

[0094] The second connecting piece 106 is connected to one end of the second hollow cavity close to the first frame, and the second connecting piece 106 and the second frame body 105 jointly form the first groove 101.

[0095] The second frame body 105 is the bottom secondary beam of the module unit 1, and the second connecting piece 106 is the bottom plate of the module unit 1. By forming the first groove 101 with the second connecting piece 106 and the second frame body 105, the first groove 101 does not need to be additionally provided, which can reduce the difficulty of providing the first groove 101, thereby achieving the technical effect of improving the convenience of providing the first groove 101.

[0096] In addition, in the embodiment, the cross sections of the first protrusion, the first groove 101, the second protrusion 1021 and the second groove 1022 are all rectangular, that is, the first protrusion and the first groove 101 are fixed along the Y-axis direction shown in the figure through plug-in connection, at the same time, the second protrusion 1021 and the second groove 1022 are fixed along the horizontal direction through plug-in connection.
