Node connection device

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This disclosure claims the benefit of and priority to Chinese Patent Application No. 202311811604X, filed on December 26, 2023, which is hereby incorporated by reference in its entirety. Technical Field

[0003] The present disclosure generally relates to the technical field of prefabricated buildings, and more particularly to a node connection device. Background Art

[0004] Modular construction is a structural system composed of multiple factory-fabricated modular building units that are quickly assembled on-site. In high-rise modular buildings, a reinforced concrete core typically serves as the central component of the structure. This core not only serves as the building's primary load-bearing and earthquake-resistant structure, but also serves as an elevator shaft, staircase, ventilation shaft, and cable duct. Steel structural units are arranged around the core to form the overall building.

[0005] During modular building construction, the concrete core is typically poured first, followed by the individual connection of multiple steel building units to the core. As the number of building units increases, the stacked steel components inevitably experience settlement due to their own weight, the weight of the decoration, occupants, and other objects, as well as the impact of the foundation. In existing modular buildings, the connection between the steel components and the concrete core is a rigid one. This settlement creates a height difference between the steel modules and the core, compromising joint safety.

[0006] Therefore, it is necessary to provide a node connection device to at least partially solve the above problems. Summary of the Invention

[0038] Hereinafter, specific embodiments of the present disclosure will be described in more detail with reference to the accompanying drawings. These drawings illustrate representative embodiments of the present disclosure and do not limit the present disclosure.

[0039] As shown in FIG. 1 to FIG. 25 , the present disclosure provides a node connection device for connecting a modular building 10 and a concrete core 20 .

[0040] The node connection device includes a first connection member, a second connection member and a third connection member, wherein the first connection member is used to connect to the modular building, and the second connection member is used to be fixedly connected to the concrete core tube and is at least partially located outside the concrete core tube.

[0041] The third connecting member is connected to the first connecting member and the second connecting member. Specifically, the third connecting member is fixedly connected to one of the first connecting member and the second connecting member and is configured to be movable relative to the other of the first connecting member and the second connecting member along the vertical direction D1.

[0042] The first connector and the second connector are connected by a third connector, and when the first connector and the second connector produce relative displacement along the vertical direction D1, the first connector and the second connector can still be connected by the third connector. It can be understood that when the modular building 10 is stacked, it will cause settlement, resulting in a height difference (relative displacement in the vertical direction D1) between the modular building 10 and the concrete core tube 20. This height difference can be absorbed by the third connector to avoid affecting the safety of the connection node between the modular building 10 and the concrete core tube 20. In other words, when settlement occurs between the modular building 10 and the core tube 20, the node connection device disclosed in the present invention can absorb the settlement displacement, avoid settlement damage, and ensure the safety of the node and the building.

[0043] Specifically, referring to Figure 25 and Figures 1 to 3c, two modular buildings 10 stacked along a vertical direction D1 can be connected at a corner or on the outer circumference via a connecting device 30. Exemplarily, the connecting device 30 includes a positioning member 31, a locking member 32, and a connecting box 33. The connecting box 33 is positioned at a corner of one of the two modular buildings stacked along the vertical direction D1, while the positioning member 31 and the locking member 32 are positioned at a corner of the other modular building. The positioning member 31 cooperates with the connecting box 33 to achieve stacking of the two modular buildings 10; the locking member 32 cooperates with the connecting box 33 to achieve connection and locking of the two modular buildings. The positioning member 31 can be, for example, a positioning bolt. The locking member 32 can be, for example, a locking bolt. The first connecting member 110 can be connected to the connecting device 30 to achieve connection and fixation with the modular building 10.

[0044] The first connector 110 includes a first sub-plate 111, which can be installed between two modular buildings 10. Referring to Figures 1 to 3c, two first through-holes 113 are provided in the first sub-plate 111. One of the two first through-holes 113 is designed to engage with a positioning member 31, and the other of the two first through-holes 113 is designed to engage with a locking member 32. Specifically, after passing through the first sub-plate 111, the positioning member 31 and the locking member 32 connect to the connection box 33, thereby connecting and securing the first connector 110 to the modular building 10.

[0045] The second connector 120 includes an anchor bar 124. One end of the anchor bar 124 is embedded in the concrete core 20, and the other end of the anchor bar is located outside the concrete core 20 (protruding from the outer surface of the concrete core 20). For example, the anchor bar 124 can be configured in a bent shape. The end of the anchor bar 124 located outside the concrete core 20 can be connected to the first connector 110 via a third connector 130.

[0046] The specific structure of the node connection device disclosed herein will be described in detail below with reference to the embodiments shown in the accompanying drawings.

[0047] Example 1

[0048] As shown in Figures 1 to 3c, in a first embodiment of the present disclosure, a first connector 110 includes a first sub-panel 111 and a second sub-panel 112 connected perpendicularly to each other. First sub-panel 111 is provided with a first through-hole 113 for connecting to modular building 10. In Figure 2, first sub-panel 111 and second sub-panel 112 are connected in a T-shape. First sub-panel 111 and second sub-panel 112 can also be connected in an L-shape.

[0049] Referring to Figures 2 to 3c , first sub-panel 111 extends in a horizontal direction D2, and second sub-panel 112 extends in a vertical direction D1. After first sub-panel 111 is connected to the connecting device, second sub-panel 112 is located outside modular building 10 and serves as a connection portion for third connector 130.

[0050] Referring to Figure 2 , in this embodiment, the second connector 120 includes multiple anchor bars 124, each of which is configured in a bent shape. One end of the anchor bar 124 is embedded in the concrete core tube 20, while the other end of the anchor bar 124 is located outside the concrete core tube 20, serving as a connection end for the third connector 130. Specifically, the anchor bars 124 include a first anchor bar 121 and a second anchor bar 122. The first anchor bar 121 and the second anchor bar 122, embedded in the concrete core tube 20, extend in different directions, thereby achieving a reliable connection between the node connection device 100 and the concrete core tube 20.

[0051] The third connector 130 includes a first connecting plate 131. A connecting hole 131a is provided on the first connecting plate 131. The connecting hole 131a is configured as an elongated hole extending along the vertical direction D1. One of the first connector 110 and the second connector 120 is fixedly connected to the first connecting plate 131, while the other of the first connector 110 and the second connector 120 is movably connected to the connecting hole 131a and configured to move along the connecting hole 131a.

[0052] In this embodiment, the first connecting plate 131 is fixedly connected to the first connecting member 110, and the second connecting member 120 is connected to the connecting hole 131a. When the modular building 10 settles, resulting in a height difference with the concrete core 20, the first connecting plate 131 can move relative to the concrete core 20 along with the first connecting member 110, thereby generating relative movement between the second connecting member 120 and the connecting hole 131a. In alternative embodiments of the present disclosure, the first connecting plate can be fixed to the second connecting member, while the first connecting member can be movably connected to the connecting hole.

[0053] The second sub-plate 112 can be connected to the first connecting plate 131 by welding, riveting or screw connection. Optionally, when the first connecting plate 131 is connected to the second sub-plate 112, the first connecting plate 131 and the second sub-plate 112 are in contact (see Figures 1 and 3a to 3c).

[0054] The number of connection holes 131a corresponds to the number of anchor bars 124, and the positions of connection holes 131a also adapt to the positions of anchor bars 124. Optionally, when the node connection device 100 is assembled, the anchor bars 124 are located in the middle of the connection holes 131a in the extension direction (vertical direction D1).

[0055] Optionally, the connection end of the anchor bar 124 located outside the concrete core tube 20 is provided with an external thread, and the anchor bar 124 is connected to the connection hole 131a and then connected to the first nut 123, thereby preventing the anchor bar from escaping from the connection hole 131a.

[0056] Example 2

[0057] As shown in FIG. 4 to FIG. 6 c , in the second embodiment of the present disclosure, the node connection device 100 is different from the first embodiment in the structure of the first connection member 110 .

[0058] Specifically, referring to Figures 4 to 6c , first connector 110 comprises only a first sub-plate 111 extending along horizontal direction D2. When node connection device 100 is assembled, the end of first sub-plate 111 facing first connecting plate 131 is directly fixedly connected to first connecting plate 131. First sub-plate 111 can be welded to first connecting plate 131, for example.

[0059] Compared to Example 1, the node connection device 100 in Example 2 has a simpler structure and is smaller in size. However, the first sub-plate 111 is relatively thin, making welding difficult during installation and requiring high welding quality to ensure structural strength at the weld locations. In Example 1, the first connector 110 is equipped with the second sub-plate 112, which increases the contact area between the first connector 110 and the first connecting plate 131, facilitating connection between the first connector 110 and the first connecting plate 131.

[0060] Example 3

[0061] As shown in Figures 7 to 9c, in the third embodiment of the present disclosure, the first connecting member 210 of the node connecting device 200 includes a first sub-plate 211, which is provided with a first through hole 213. The second connecting member 220 of the node connecting device 200 includes a first anchor bar 221 and a second anchor bar 222.

[0062] Unlike the previous embodiment, in this embodiment, the third connector 230 includes a first connecting plate 231 and a second connecting plate 232. The first sub-plate 211 is welded to the first connecting plate 231. The first anchor rib 221 and the second anchor rib 222 are fixedly connected (e.g., welded or threaded) to the second connecting plate 232 (see FIG8 ). The first connecting plate 231 is provided with a connecting hole 231a, which is configured as an elongated hole extending along the vertical direction D1.

[0063] A second through-hole 232c is provided on the second connecting plate 232. A connecting bolt 232a is inserted through and connects the second through-hole 232c and the connecting hole 231a, and engages with a second nut 232b to achieve connection between the first connecting plate 231 and the second connecting plate 232. Furthermore, when the modular building settles, causing a height difference with the concrete core, the first connecting plate 231 can move relative to the concrete core along the vertical direction D1 along with the first connector 210, causing relative movement between the second connector 220, the second connecting plate 232, and the connecting bolt 232a and the connecting hole 231a.

[0064] During the actual installation process, the first sub-panel 211 and the first connecting plate 231 may be welded and fixed before the first sub-panel 211 is connected to the modular building.

[0065] Example 4

[0066] As shown in Figures 10 to 12c, in the fourth embodiment of the present disclosure, the node connection device 200 differs from the third embodiment in the structure of the first connector 210. Specifically, the first connector 210 includes a first sub-plate 211 and a second sub-plate 212, which are vertically connected and form a T-shape. In this embodiment, the second sub-plate 212 is welded to the first connecting plate 231.

[0067] Considering that it is difficult to align the connection hole 231a on the first connecting plate 231 with the second through hole 232c (such as a bolt hole) on the second connecting plate 232 after the first sub-plate 211 is welded and fixed to the first connecting plate 231 and aligned with the modular building and connected, the first connecting member 210 is configured as a T-shaped plate. At this time, the first connecting plate 231 and the second connecting plate 232 can be connected first, and then the second sub-plate 212 can be welded to the first connecting plate 231.

[0068] The relevant beneficial effects of this embodiment can be specifically referred to the aforementioned embodiments and will not be described in detail here.

[0069] In the above embodiment, the first connecting member is movable relative to the second connecting member in the vertical direction D1 by fixedly connecting one of the first connecting member and the second connecting member to the first connecting plate and movably connecting the other of the first connecting member and the connecting hole.

[0070] In other embodiments of the present disclosure, the third connector 330 may further include a connecting portion 334 and a mating portion 335. One of the connecting portion and the mating portion is attached to the first connector 310, and the other is attached to the second connector 320. The connecting portion and the mating portion are configured to move relative to each other along the vertical direction D1. When the modular building settles, resulting in a height difference with the concrete core, the connecting portion and the mating portion move relative to each other along the vertical direction D1.

[0071] For example, the connecting portion 334 can be configured as a slide member 332 having a slide 332b extending along the vertical direction D1. The mating portion 335 can be configured as a slider member 331 mating with the slide 332b. The length of the slide 332b in the vertical direction D1 can be flexibly adjusted according to actual needs.

[0072] Optionally, the chute 332b is configured as a dovetail groove 336. In this case, the slider 331b and the chute 332b can only move relative to each other along the vertical direction D1. To further adjust the tightness of the fit between the slider 331b and the dovetail groove 336, the third connector 330 further includes an adjustment bolt 333. The adjustment bolt 333 is connected to one of the chute member 332 and the slider member 331 and is configured to move relative to the other of the chute member 332 and the slider member 331 along the opening direction of the dovetail groove 336 to adjust the gap between the slider 331b and the dovetail groove 336. It will be appreciated that the number of adjustment bolts 333 can be flexibly selected according to actual needs.

[0073] It can be understood that when the slide member 332 is connected to the first connecting member 310 , the slider member 331 can be connected to the second connecting member 320 ; when the slider member 331 is connected to the first connecting member 310 , the slide member 332 can be connected to the second connecting member 320 .

[0074] Example 5

[0075] As shown in Figures 13 to 15c, in the fifth embodiment of the present disclosure, the first connecting member 310 of the node connecting device 300 includes a first sub-plate 311, which is provided with a first through hole 313. The second connecting member 320 of the node connecting device 300 includes a first anchor bar 321 and a second anchor bar 322.

[0076] Unlike the previous embodiment, in this embodiment, the third connecting member 330 includes a slider member 331 and a slide groove member 332. The slide groove member 332 is formed with a slide groove 332b extending along the vertical direction D1. The slider member 331 includes a slider 331b that matches the slide groove 332b. When the slider member 331 and the slide groove member 332 are connected, the slider 331b can move along the slide groove 332b.

[0077] Referring to Figure 14, the slider member 331 includes a third connecting plate 331a and a slider 331b. The third connecting plate 331a is fixedly connected to the first sub-plate 311, and the slider 331b is attached to the third connecting plate 331a. The chute member 332 includes a fourth connecting plate 332a and a fifth connecting plate 332c. The fourth connecting plate 332a is formed with a chute 332b, and the fifth connecting plate 332c is fixedly connected to the first anchor bar 321 and the second anchor bar 322. The fourth connecting plate 332a and the fifth connecting plate 332c are fixedly connected.

[0078] As shown in Figures 13 and 15a to 15c, the sliding groove 332b is configured as a dovetail groove 336, with the opening of the dovetail groove 336 horizontally facing the slider 331b. The third connecting plate 331a is provided with third through holes 331c, one on each side of the slider 331b, and the adjusting bolts 333 are connected to the third through holes 331c.

[0079] Example 6

[0080] As shown in Figures 16 to 18c, in the sixth embodiment of the present disclosure, the node connection device 300 differs from the fifth embodiment in the structure of the first connection member 310. Specifically, the first connection member 310 includes a first sub-plate 311 and a second sub-plate 312, which are vertically connected and form a T-shape.

[0081] In addition, considering that the second sub-board 312 has a certain area, the sizes of the third connecting board 331 a and the fourth connecting board 332 a are correspondingly increased in this embodiment.

[0082] The second sub-plate 312 can be welded to the third connecting plate 331a or can be screwed to the third connecting plate 331a. Referring to FIG17 , in order to facilitate the installation of the adjustment bolt 333 , the second sub-plate 312 is provided with a fourth through hole 312a.

[0083] The beneficial effects of this embodiment can be specifically described with reference to the aforementioned embodiments, which will not be elaborated here.

[0084] Example 7

[0085] As shown in Figures 19 to 21c , in the seventh embodiment of the present disclosure, the node connection device 300 differs from the fifth embodiment in the structure of the slider member 331. Specifically, the slider member 331 comprises only a slider 331b, which is attached to the first sub-plate 311. This further simplifies the structure of the node connection device 300. In actual production, the slider 331b and the first sub-plate 311 can be directly integrally formed.

[0086] The beneficial effects of this embodiment can be specifically described with reference to the aforementioned embodiments, which will not be elaborated here.

[0087] Example 8

[0088] As shown in Figures 22 to 24c, in the eighth embodiment of the present disclosure, the first connecting member 410 of the node connecting device 400 includes a first sub-plate 411 having a first through-hole 413. The second connecting member 420 of the node connecting device 400 includes a first anchor bar 421 and a second anchor bar 422.

[0089] The difference from the previous embodiment is that the third connecting member 430 of the node connecting device 400 in this embodiment includes a first ear plate 431, a base 433 and a connecting shaft 434. The first ear plate 431 and the base 433 are connected to the first connecting member 410 and the second connecting member 420 respectively.

[0090] Referring to Figure 23 , two second lugs 432 are provided on the base 433, spaced a predetermined distance apart along the vertical direction D1. When the joint connection device 400 of the present disclosure is used to connect a modular building to a concrete core, the first lug 431 is positioned between the two second lugs 432 along the vertical direction D1. Through holes are provided in each of the first and second lugs 431, 432 for connecting to a connecting shaft 434.

[0091] 23 to 24 c , the connecting shaft 434 extends along the vertical direction D1. Optionally, to prevent the connecting shaft 434 from falling out, a stopper 436 may be provided. The connecting shaft 434 sequentially connects to the second lug plate 432, the first lug plate 431, and the second lug plate 432 before being connected to the stopper 436.

[0092] In this embodiment, the stopper 436 is a stopper pin 435. One end of the connecting shaft 434 is larger than the hole in the second lug 432. The other end of the connecting shaft 434 is provided with a radial hole for receiving the stopper pin 435. When the connecting shaft 434 is connected to the first and second lugs 431, 432, and then extends from the second lug 432, the stopper pin 435 is inserted into the radial hole, thereby connecting the first connector 410 to the second connector 420.

[0093] It is understood that when the modular building has a height difference with the concrete core due to settlement, the first ear plate 431 can move along the connecting axis 434 between the two second ear plates 432 in the vertical direction D1. In addition, the first connector 410 and the second connector 420 can also rotate about the connecting axis 434 (the third connector 430 can also absorb the rotation).
