[0023] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially for illustrative purposes rather than for limiting the present invention.

[0024] In the description of the present invention, it should be understood that in the embodiments shown in the drawings, the indications of directions or positional relationships (such as up, down, left, right, front and back, etc.) are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific orientation, be constructed and operate in a specific orientation. These descriptions are appropriate when these elements are in the positions shown in the drawings. If the descriptions of the positions of these elements change, the indications of these directions also change accordingly.

[0025] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0026] In the field of modular buildings, when modular buildings are assembled, a joint with a width of about 20 mm will be generated between the modules. In addition, due to the error in the precision of structural hoisting, the floor of the building interior generally has a horizontal height error of 0-20 mm. As a result, when decorating the interior, the floor needs to be leveled, which is labor-intensive and time-consuming. In addition, when modular buildings are dismantled, replaced, moved, and recycled, the interior decoration structure at the joint position will be destroyed, resulting in high costs for later maintenance and recycling. Therefore, a joint structure is proposed to solve the above problems.

[0027] The scheme is further illustrated by the following examples:

[0028] See also Figure 1 and Figure 2 The modular building 1 of this embodiment includes a modular building 1 and a joint structure. Specifically, a plurality of modular buildings 1 are provided, and the plurality of modular buildings 1 can be stacked to form a residential unit such as a building. The joint structure is connected to the joints of the modular building 1, so that the joint structure can cover the joints of the modular building 1, so that the joints can be kept flush with the ground of the modular building 1, which is convenient for the subsequent decoration of the building.

[0029] In this embodiment, the joint structure is detachably connected to the joints of the modular building 1, so that after the modular building 1 is stacked, the joint structure can be conveniently installed at the joints to achieve rapid leveling of the joints; or when the building units are dismantled, replaced, moved or recycled, the joint structure can be conveniently disassembled from the joints, thereby improving construction efficiency.

[0030] See also Figure 1 and Figure 2 The modular building 1 further includes a filling piece 2. The filling piece 2 is filled in the joint and is located on the side of the joint structure facing the modular building 1, thereby sealing the joint and preventing water vapor, dust and other pollutants from entering the modular building 1 along the joint space.

[0031] In this embodiment, the filling member 2 can be configured as a rubber strip and a fire-resistant rubber, thereby achieving both sealing and fire-proofing effects.

[0032] See also Figure 1 , Figure 2 and Figure 3 The joint structure of the present application is used to be installed at the joint of two adjacent modular buildings 1. Specifically, the joint structure includes a connecting member 10 and a bearing member 20.

[0033] The connector 10 is provided with a fixed side 11 and an extended side 12. The fixed side 11 is used to be fixed on one modular building 1, and the extended side 12 extends toward another modular building 1 and extends to the joint, so that the connector 10 can lie across the joint. It should be noted that the fixed side 11 can be detachably connected to the modular building 1 by screws, so as to facilitate the installation or removal of the connector 10. Of course, in some other embodiments, the fixed side 11 can also be directly fixed to the modular building 1.

[0034] The carrier 20 is provided with a connection portion 21 and two wing panels 22. The two wing panels 22 are respectively connected to both sides of the connection portion 21, and the free sides of the two wing panels 22 extend opposite to each other. The carrier 20 is detachably connected to the extension side 12 by fasteners 31, and the free ends of the two wing panels 22 can respectively abut against the two modular buildings 1, so that the carrier 20 can cover the joints.

[0035] It should be noted that the bearing member 20 is detachably connected to the extended side 12 of the connecting member 10 via the fastener 31, which can facilitate the bearing member 20 to be installed on the connecting member 10 or to be removed from the connecting member 10, thereby improving construction efficiency.

[0036] In addition, since the carrier 20 is connected to the joint by the connector 10, the carrier 20 can select the connection point between the carrier 20 and the connector 10 according to the structure of the joint, so that the carrier 20 can adapt to different joint structures. For example, when the joint is uneven, the carrier 20 is connected to the connector 10 by the fastener 31, and the posture of the carrier 20 is adjusted so that the carrier 20 covers the joint, such as Figure 1 When the joint is smooth, the carrier 20 can be directly connected to the connecting member 10 through the fastener 31, without adjusting the posture of the carrier 20 relative to the connecting member 10, so that the carrier 20 can be connected to the connecting member 10 in an ideal state, as shown in FIG. Figure 2 Therefore, the bearing member 20 is connected to the joint through the connecting member 10, which can improve the adaptability of the bearing member 20 to the joint structure, so that the joint structure can adapt to different joints.

[0037] In this embodiment, the two wing plates 22 of the bearing member 20 are formed with a certain curvature, so that when the bearing member 20 is installed at the joint, the bearing member 20 is pressed by tightening the fastener 31, so that the free end of the wing plate 22 can be better fitted on the modular building 1. At the same time, in actual use, the curvature between the two wing plates 22 can be adjusted by adjusting the tightening degree of the fastener 31, so that the bearing member 20 and the ground of the modular building 1 are more flat, which is convenient for construction and decoration.

[0038] See also Figure 1 and Figure 3 The connecting portion 21 is provided with a mounting groove 211. The mounting groove 211 is open on the side facing away from the modular building 1, so as to facilitate the installation of the fastener 31 through the open opening. At the same time, a through hole is provided in the mounting groove 211, and the fastener 31 is inserted into the through hole and connected to the extension side 12, so as to fasten the bearing member 20 to the connecting member 10.

[0039] In this embodiment, one end of the fastener 31 facing away from the extension side 12 is accommodated in the installation groove 211, thereby preventing the end of the fastener 31 from protruding from the upper surface of the carrier 20, thereby ensuring the beauty of the joint structure after installation.

[0040] See also Figure 2 and Figure 3 The joint structure further includes a cover plate 23. The cover plate 23 is engaged in the mounting groove 211, and the side of the cover plate 23 away from the mounting groove 211 and the sides of the two wing plates 22 away from the mounting groove 211 are kept flat, thereby ensuring the beauty of the bearing member 20 and facilitating the decoration of the building.

[0041] See also Figure 3 , the cover plate 23 is formed with two opposite snap-in ribs 231 protruding toward one side of the mounting groove 211. Specifically, the two snap-in ribs 231 are arranged at intervals and are adapted to the two side walls of the mounting groove 211, so that the cover plate 23 can be snapped into the mounting groove 211 through the snap-in ribs 231. That is, the two snap-in ribs 231 are respectively pressed against the two side walls of the mounting groove 211, so that the cover plate 23 can be snapped into the mounting groove 211, and the cover plate 23 is prevented from being separated from the carrier 20.

[0042] See also Figure 3 The carrier 20 is provided with a step 24 at the opening of the mounting groove 211, and the two ends of the cover plate 23 along the opposite directions of the two clamping ribs 231 overlap on the step 24. That is, the edge of the cover plate 23 can overlap on the step 24, so that the connection between the cover plate 23 and the carrier 20 remains flat, and the connection between the carrier 20 and the cover plate 23 is beautiful.

[0043] In this embodiment, the joint structure also includes a damping member 25, and the damping member 25 is arranged on the step 24, and both ends of the cover plate 23 are attached to the damping member 25, thereby increasing the friction coefficient between the cover plate 23 and the supporting member 20, so as to improve the tightness of the connection between the supporting member 20 and the cover plate 23.

[0044] In this embodiment, the connecting member 10 and the bearing member 20 are both metal members to improve the connection strength between the bearing member 20 and the connecting member 10. At the same time, the cover plate 23 can be set as a metal member. Of course, it can also be set as a member of a material such as plastic to be clamped in the installation groove 211.

[0045] Meanwhile, the fastener 31 is a screw, so that the carrier 20 is detachably connected to the extension side 12 by the screw, thereby facilitating the installation or disassembly between the carrier 20 and the connecting member 10 .

[0046] In summary, the bearing member 20 is connected to the joints of the two modular buildings 1 through the connecting member 10, so that the bearing member 20 can cover the joints and ensure the levelness of the joints, which is convenient for leveling when decorating the modular buildings 1. At the same time, the bearing member 20 is detachably connected to the connecting member 10 through the fastener 31, which can facilitate the installation or removal of the bearing member 20, and further facilitate the installation and decoration of the modular buildings 1, or facilitate the removal, movement or replacement of the modular buildings 1.

[0047] Although the utility model has been described with reference to several typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the utility model can be implemented in a variety of forms without departing from the spirit or essence of the utility model, it should be understood that the above-mentioned embodiments are not limited to any of the aforementioned details, but should be widely interpreted within the spirit and scope defined by the attached claims, so all changes and modifications falling within the scope of the claims or their equivalents should be covered by the attached claims.
