Each group of connection components adopts two connecting parts to be plugged into each other, and grouting is performed between the connection kit and the anti-pull-out plug, so as to realize the connection between two adjacent steel structure modules. At the same time, the anti-pull-out plug of each connecting part is opposite to the side wall end face of the column on the other connecting part, that is, the anti-pull-out plug and the column overlap in the force direction. The bending transmission efficiency at the entire connection node is higher, and the stress on the node is smaller. Compared with the prior art, the connection node has the characteristics of simple structure, clear force transmission path, easy construction, etc., and has good applicability and economy.

[0027] In order to better understand the above technical solution, exemplary embodiments of the present invention will be described in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a clearer and more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0028] Embodiment 1:

[0029] Reference Figure 1 This embodiment provides a connection node for staggered stacked steel structure modules, the connection node includes at least one group of connection components 6, each group of connection components 6 includes two connectors 1, and the connectors 1 are used to be arranged at the ends of the columns 2 in adjacent steel structure modules. Each connector 1 includes a plate body 14 arranged on the end surface of the column 2, and a connection kit 11 and an anti-pullout plug 12 arranged in parallel on the plate body 14. The anti-pullout plugs 12 in the two connectors 1 in each group are plugged into the connection kit 11, and a grouting space 13 is reserved between the anti-pullout plug 12 and the plugged connection kit 11 for pouring a slurry that can solidify. The rigidity of the module connection node is improved by grouting, thereby improving the overall structural performance of the modular building. After the two connectors 1 in each group are plugged in, the end face of the pull-out plug 12 is opposite to the end face of the side wall of the column 2 on the other connector 1, that is, the pull-out plug 12 and the column 2 overlap in the force direction, the bending transmission efficiency at the entire connection node is higher, the stress on the node is smaller, and the connection node can be better protected to ensure the overall performance of the overall modular building under dynamic loads such as earthquakes and wind. Here, the column 2 of the modular building is a hollow square steel.

[0030] In addition, the anti-pullout plugs 12 and the connection sets 11 in the two connecting members 1 in each group are plugged into each other, so as to realize the staggered stacking distribution between the steel structure modules.

[0031] Reference Figure 1, this embodiment provides a connection node for staggered stacked steel structure modules, the connection kit 11 and the anti-pull-out plug 12 are both vertically arranged on the same side of the plate body 14, and the other side of the plate body 14 is used to connect the column 2. Specifically, the anti-pull-out plug 12 is a channel steel, and when the two connectors 1 in each group are plugged in, the web 122 of the channel steel is aligned with a side wall of the column 2 on the other connector 1, that is, the web 122 and a side wall of the column 2 are located in the same plane. It should be noted here that the columns 2 of adjacent steel structure modules are usually located on the same straight line in the vertical direction, so when the web 122 of the channel steel is aligned with a side wall of the column 2 on the other connector 1, the web 122 of the channel steel is also aligned with a side wall of the column 2 on the connector 1 where it is located. This arrangement in which the anti-pull-out plug 12 is aligned with the side wall of the column 2 has a clear force transmission path, which is conducive to the force transmission of the node.

[0032] The pull-out plug 12 is a channel steel, and correspondingly, the connection kit 11 is a U-shaped structure, and a U-shaped groove is provided inside the U-shaped structure to adapt to the channel steel. When two connectors 1 are plugged in, the end of the connection kit 11 of one connector 1 is snapped into the plate body 14 of the other connector 1. The connection kit 11 and the plate body 14 can be used to adjust the flatness of the installation by a gasket.

[0033] Reference Figure 1 This embodiment provides a connection node for staggered stacked steel structure modules, and a partition 111 is provided at the corner inside the connection kit 11, and the partition 111 is perpendicular to the connection kit 11. The function of the partition 111 is to enhance the force performance of the connection kit 11. In order to make the partition 111 play a better role, the partition 111 can be aligned with the position of the beam 3 at the connection node, so that the beam 3 can transmit force more conveniently.

[0034] Reference Figure 1 This embodiment provides a connection node for staggered stacked steel structure modules. A plurality of first shear bolts 112 are arranged on the circumferential inner wall of the connection kit 11, and the plurality of first shear bolts 112 are arranged in a plurality of vertical columns. A plurality of second shear bolts 121 are arranged on the outer surface of the pull-out plug 12, and the plurality of second shear bolts 121 are arranged in a plurality of vertical columns. When the pull-out plug 12 is inserted into the connection kit 11, the vertical columns composed of the first shear bolts 112 and the vertical columns composed of the second shear bolts 121 are staggered with each other in the horizontal direction, which is beneficial to the node force transmission. The first shear bolts 112 and the second shear bolts 121 have the same structure, both including a circular plate and a connecting rod fixedly connected to one side of the circular plate.

[0035] Reference Figure 1This embodiment provides a connection node for staggered stacked steel structure modules. When the two connectors 1 in each group are plugged in, the upper parts of the two connection sets 11 are provided with grouting holes and grouting holes 114, and the position of the grouting holes 114 is not lower than the grouting holes. In order to facilitate grouting, pipe sections can be extended outward from the grouting holes and the grouting holes 114. In addition to fixing the two connectors 1 in each group of connection components 6, the solidified slurry in the connection set 11 also acts as a force transmission medium of the connection component 6 in conjunction with the first shear bolt 112 and the second shear bolt 121.

[0036] Reference Figure 1 This embodiment provides a connection node for staggered stacked steel structure modules. A reinforcement member 15 is provided at the connection between the connector 1 and the steel structure module. The reinforcement member 15 is specifically arranged at the connection between the connector 1 and the crossbeam 3 and the column 2 of the steel structure module to improve the connection strength.

[0037] Embodiment 2:

[0038] The present embodiment provides a connection node for staggered stacked steel structure modules, including two groups of connection components 6, a connection member 1 in one group of connection components 6 is connected to a connection member 1 in another group of connection components 6 in parallel and adjacent to each other in the horizontal direction, and another connection member 1 in one group of connection components 6 is connected to another connection member 1 in another group of connection components 6 in parallel and adjacent to each other in the horizontal direction; the two connection members 1 in each group are plugged in to form a connection node.

[0039] Reference Figure 2 , two groups of connection components 6 are arranged in parallel along the horizontal direction, and each connection member 1 corresponds to a steel structure module. Then the connection node can simultaneously connect 4 steel structure modules, which are divided into 2 groups, and the 2 steel structure modules located on the same floor are arranged side by side and adjacent to each other, which meets the assembly needs of different building structures and improves the assembly efficiency. The two connection components 6 are connected by at least one first connection plate 4, referring to Figure 2 , the connection between the two parallel connecting members 1 located at the bottom: the first connecting plate 4 is horizontally arranged on the opening edge of the two parallel connecting sets 11, and the opening is used for the corresponding anti-pullout plug-in 12 to be inserted or pulled out. In this way, the two parallel connecting sets 11 are horizontally connected, that is, the two groups of connecting components 6 are connected in the horizontal direction. The first connecting plate 4 can be arranged on the two parallel connecting sets 11 by welding or the aforementioned grouting method. In addition, the first connecting plate 4 also plays a role in adjusting the connection flatness. In addition, a first connecting plate 4 can also be arranged at the lower end of the two parallel connecting sets 11 located at the top, so that the two groups of connecting components 6 are double-connected in the horizontal direction.

[0040] Embodiment 3:

[0041] Reference Figure 3This embodiment provides a connection node for staggered stacked steel structure modules. Two groups of connection components 6 are arranged in parallel in the horizontal direction. The difference from the embodiment 2 is that one of the connection components 6 is vertically flipped 180° relative to the other group of connection components 6. In this way, each connector 1 corresponds to one steel structure module, so the connection node can connect four steel structure modules at the same time, where two steel structure modules on the same layer are centrally symmetrically distributed relative to the two connection assemblies, which meets the assembly needs of different building structures and improves assembly efficiency. The two groups of connection components 6 are connected by at least one second connection plate 5. Figure 3 , the connection between the two horizontally adjacent connectors 1 located at the bottom: the second connecting plate 5 is horizontally inserted into the fixed end of the anti-extraction plug 12, and is connected to the connecting sleeve 11 of another horizontally adjacent connector 1. The second connecting plate 5 is welded and fixed to the connecting sleeve 11 and the plate body 14 of the fixed end of the anti-extraction plug 12. Correspondingly, a second connecting plate 5 can also be set between the two parallel connectors 1 located at the top. For specific connection methods, refer to Figure 3 , no further explanation is given, thus achieving double connection of the two groups of connecting components 6 in the horizontal direction.

[0042] It is also necessary to explain that two second connecting plates 5 can be arranged between two parallel connecting members 1, and the two second connecting plates 5 are respectively connected to the connecting sets 11 and the plates 14 at the fixed ends of the anti-pullout plug-in 12 on different connecting members 1.
