[0002] Modular fully assembled building structure is an emerging form of building structure. It prefabricates modular units in factories, then transports them to the target site and assembles them into a structure or structural body with complete functions through reliable connections between modules. Compared with traditional construction forms, modular structure transfers a large amount of on-site construction work to factories, which brings the following significant advantages: short construction period, low cost, good quality, safe construction, green and environmental protection, etc. Therefore, it can be expected that modular fully assembled building structure will become one of the mainstream building forms in the future, promoting green, sustainable and high-quality development in the field of building structure.

[0003] The overall performance of modular, fully assembled building structures depends largely on the mechanical properties of the inter-module connections. These connections form force transmission paths between adjacent modules, integrating them into the overall structure and thus impacting the overall safety of the modular structure. The design of these connections must not only meet mechanical performance requirements but also consider ease of operation during on-site assembly.

[0004] Existing connection nodes between modules are usually connected by on-site bolts or welding, which has problems such as large on-site workload and construction quality being greatly affected by the construction environment and the skills of construction personnel.

DETAILED DESCRIPTION

[0029] The present invention provides a self-locking connector between modules of a modular, fully assembled building structure. To clarify the objectives, technical solutions, and effects of the present invention, the present invention is described in further detail below. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention.

[0030] It will be understood by those skilled in the art that, unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by those skilled in the art in the art to which the present invention belongs. It should also be understood that terms such as those defined in common dictionaries should be understood to have meanings consistent with their meanings in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless specifically defined as herein.

[0031] like Figure 1-4 As shown, the present invention provides a self-locking connector between modules of a modular fully assembled building structure, comprising a plurality of connector units 100;

[0032] The connector unit 100 includes:

[0033] The female connector part 10 is provided with a groove 11; the sidewall of the groove 11 is provided with a plurality of female lock holes 12 and lock tongues 13 corresponding to the female lock holes 12; the female lock holes 12 are provided with lock hole covers 14 for restricting the lock tongues 13 from passing through the female lock holes 12;

[0034] The male connector part 20 is provided with a connecting rod 21 matching the groove 11 ; the connecting rod 21 is provided with a male locking hole 22 matching the female locking hole 12 .

[0035] In this embodiment, the inter-module self-locking connector includes a connector unit 100, which includes a female connector 10 and a male connector 20. It serves to connect and fix modular prefabricated building modules without the need for on-site bolting or welding operations. The male connector 20 and the female connector 10 are respectively arranged at the corners of adjacent building modules in the upper and lower, left and right directions and connected to the internal steel structure or steel tube concrete structure beam and column components of the module. After the adjacent building modules are arranged to the designated position, the connecting rod of the male connector is inserted into the groove of the female connector. The connecting rod is used to push open the lock hole cover, triggering the lock tongue to pass through the female lock hole and the male lock hole to achieve automatic locking, so that the building modules are connected to form a complete building structure or structural body. This self-locking connector is suitable for multi-story modular fully prefabricated buildings, including steel structures and steel tube concrete structures.

[0036] In some embodiments, the connector mother part 10 is provided with a plurality of limit rods 15 and a plurality of springs 16 coaxially arranged with the plurality of limit rods 15; one end of the spring 16 is connected to the inner wall of the connector mother part 10, and the other end abuts against the side of the lock tongue 13 away from the mother part lock hole 12.

[0037] Specifically, the limiting rod 15 is arranged corresponding to the female lock hole 12, which serves to guide the spring 16 and the lock tongue 13, so that the lock tongue 13 can pass through the female lock hole 12 and the male lock hole 22 along the limiting rod 15, thereby realizing the locking of the connector male part 20 and the connector female part 10.

[0038] In some embodiments, the limiting rod 15 is disposed through the axis of the locking tongue 13 and forms a sliding connection with the locking tongue 13. The locking tongue 13 can be inserted into the female locking hole 12 and the male locking hole 22 along the limiting rod 15 under the thrust of the spring 16, thereby achieving locking of the female connector 10 and the male connector 20.

[0039] In some embodiments, as Figure 5 As shown, the cross-sectional diameter of the female lock hole 12 is larger than the cross-sectional diameter of the lock tongue 13 .

[0040] Specifically, the lock tongue 13 is inserted into the female lock hole 12 and the male lock hole 22 along the axial direction of the limit rod 15 under the drive of the spring 16, thereby realizing automatic locking; and the length of the limit rod 15 is less than the displacement distance of the lock tongue 13 driven by the spring 16. After the lock tongue 13 is separated from the limit rod 15, since the cross-sectional diameter of the female lock hole 12 is larger than the cross-sectional diameter of the lock tongue 13, and under the action of gravity, the lock tongue 13 is displaced and deflected in the vertical direction and is no longer coaxial with the limit rod 15, so that the lock tongue 13 cannot return to the original path under natural conditions, thereby preventing the lock tongue 13 from accidentally falling off under non-human conditions, thereby improving the safety and reliability of the connection node.

[0041] In a preferred embodiment, the lock tongue 13 includes a lock tongue body 131 and a lock tongue end 132. The lock tongue body 131 and the lock tongue end 132 are an integrated structure. The lock tongue end 132 abuts against the spring 16, and the lock tongue body 131 is disposed near the female lock hole 12. The cross-sectional diameter of the lock tongue body 131 is smaller than the cross-sectional diameter of the lock tongue end. The cross-sectional diameter of the female lock hole 12 is larger than the cross-sectional diameter of the lock tongue body 131 and smaller than the cross-sectional diameter of the lock tongue end.

[0042] In some embodiments, the bottom of the groove 11 is a hollow structure; the keyhole cover 14 is covered at the bottom of the groove 11 , and the side wall of the keyhole cover 14 is attached to the outside of the groove 11 .

[0043] Specifically, the lock hole blocking cover 14 is a lid with an opening on one side, comprising a top and a sidewall disposed around the edge of the top; the sidewall is attached to the side of the groove near the limiting rod and is used to restrict the locking tongue 13 from passing through the female lock hole 12. The lock hole blocking cover 14 is disposed on the bottom of the groove 11. When the connecting rod 21 of the male connector 20 is inserted into the groove 11, the lock hole blocking cover 14 can be pushed open, allowing the lock hole blocking cover 14 to move in the same direction of movement as the connecting rod 21, thereby eliminating the female lock hole 12 from being blocked by the lock hole blocking cover 14.

[0044] In some embodiments, the groove 11 is an inward-concave square tube, and the connecting rod 21 is an outward-convex square tube; in the unconnected state, the lock hole cover is placed on the upper end of the inward-concave square tube and blocks the female lock hole, preventing the lock tongue from inserting into the female lock hole; when connected, the outward-convex square tube passes through the connecting hole and is inserted into the inward-concave square tube to push the lock hole cover upward so that the female lock hole is no longer blocked by the lock hole cover, so that the main part of the lock tongue is inserted into the female lock hole and the male lock hole along the axial direction of the limit rod under the drive of the spring, thereby achieving automatic locking.

[0045] In some embodiments, the lock hole cover 14 is movably connected to the groove 11. Under the action of the connecting rod 21, the lock hole cover 14 can be pushed open to expose the mother lock hole 12, allowing the lock tongue to pass through the mother lock hole under the push of the spring.

[0046] In some embodiments, the shape of the connector unit 100 includes but is not limited to a cylinder, a cube, or a cuboid. After the female connector and the male connector are self-locked, the shape can be a cylinder, a cube, or a cuboid, which can be selected according to actual application needs.

[0047] In some embodiments, the lock tongue 13 , the female lock hole 12 , and the male lock hole 22 are all in the shape of a circle, a rectangle, or a polygon, but are not limited thereto.

[0048] In some embodiments, the inter-module self-locking connector further includes a connecting plate 200 used in conjunction with the connector unit 100 ; the connecting plate 200 is provided with a plurality of connecting holes 30 , and the connecting holes 30 are used to pass through the connecting rods 21 .

[0049] In some embodiments, the shape of the connecting plate 200 includes but is not limited to a square or a rectangle; and / or the number of the connecting holes 30 includes but is not limited to a single hole, a double hole, or four holes.

[0050] Specifically, the shape of the connecting plate 200 and the number of the connecting holes 30 are determined according to the spatial position and number of the building modules to be connected. In a preferred embodiment, the shape of the connecting plate 200 and the number of the connecting holes 30 include but are not limited to a square single hole, a rectangular double hole and a square four hole. Figure 6 shown.

[0051] In some embodiments, the modules at the corners of the building periphery only need to be connected vertically and do not need to be connected horizontally, so the connection plate may not be needed, or a single-hole connection plate may be used to fill the gap, such as Figure 6 As shown in C.

[0052] In some embodiments, the connector female part 10 and the connector male part 20 can be connected to the internal steel structure of the module, steel tube concrete structure beam, column components, etc. through bolt connection or welding connection, and the cross-section of the connected components can be but not limited to rectangular, circular, hollow rectangular, hollow circular, "I" shape or "C" shape.

[0053] In some embodiments, the materials of the connector female part, the connecting plate and the connector male part are independently selected from but not limited to ordinary steel, high-strength steel and stainless steel.

[0054] In some embodiments, the cross-section of the locking tongue is circular, rectangular, or polygonal, but is not limited thereto.

[0055] In some embodiments, the cross-section of the connecting rod includes, but is not limited to, a circle, a rectangle, or a polygon. The shapes of the connecting hole and the groove match the shape of the connecting rod.

[0056] In some embodiments, the number of locking tongues in the female connector is 1, 2, 3, or 4, but is not limited thereto. The number of the limiting rods, the springs, the female lock holes, and the male lock holes corresponds to the number of the locking tongues.

[0057] In summary, the present invention provides a self-locking connector between modules of a modular fully assembled building structure, comprising a plurality of connector units and a connecting plate used in conjunction with the connector units; the connector units comprise: a female connector part, the female connector part being provided with a groove; the sidewall of the groove being provided with a plurality of female locking holes, and locking tongues corresponding to the female locking holes; the female locking holes being provided with a locking hole cover for restricting the locking tongues from passing through the female locking holes; a male connector part, the male connector part being provided with a connecting rod matching the groove; the connecting rod being provided with a male locking hole matching the female locking hole; the connecting plate being provided with a plurality of connecting holes, the connecting holes being provided for passing through the connecting rod. The self-locking connector between modules of the present invention uses the male and female parts to mutually insert and trigger the locking tongue to achieve connection and fixation of adjacent building modules without the need for on-site tightening operations, which can simplify on-site installation steps, thereby effectively improving construction efficiency and reducing the impact of the construction environment and construction personnel's skills on construction quality. In addition, the limit rod in the self-locking connector can guide the lock tongue to accurately insert into the female lock hole and the male lock hole, and separate from the limit rod after the lock tongue is fully inserted into the lock hole. Under the action of gravity, the limit rod and the lock tongue are no longer coaxial, so that the lock tongue cannot return to the original path under natural conditions, preventing the lock tongue from accidentally falling off due to non-human influence, effectively improving the reliability and safety of the self-locking connector.

[0058] It should be understood that the application of the present invention is not limited to the above examples. For those skilled in the art, improvements or changes can be made based on the above description. All these improvements and changes should fall within the scope of protection of the claims attached to the present invention.
