For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0028] Reference will be made to the drawings Figures 1-2 The modular slab column structure system 100 according to the embodiment of the present application is described.

[0029] As Figures 1-2 shown, the modular slab column structure system 100 according to the embodiment of the present application includes a floor slab and a plurality of support columns 10, the plurality of support columns 10 can respectively extend along a first direction (such as the up-down direction as Figure 1 shown), the floor slab can be installed on one side of the plurality of support columns 10 in the first direction (such as the upper side or the lower side as Figure 1 shown), the floor slab can include a base plate 20 and a plurality of reinforcing plates 30, the base plate 20 has a plurality of notches at the edges, the plurality of notches and the plurality of support columns 10 one-to-one correspond, the plurality of reinforcing plates 30 are respectively arranged in the plurality of notches, and the plurality of reinforcing plates 30 can be respectively connected with the base plate 20.

[0030] The structural strength of the reinforcing plate 30 can be higher than that of the base plate 20. The floor slab can be connected to the support column 10 through the reinforcing plate 30, which can improve the structural strength of the connection between the floor slab and the support column 10. This allows the connection between the floor slab and the support column 10 to withstand greater shear force, improve the punching shear resistance of the connection between the floor slab and the support column 10, and prevent punching shear failure of the connection between the floor slab and the support column 10 due to external loads. This can improve the safety and reliability of the plate-column structure (the connection structure formed by assembling the floor slab and the support column 10) and reduce the safety hazards of the modular plate-column structure system 100.

[0031] Understandably, the base plate 20 can select the concrete type according to design requirements (concrete specifications, seismic specifications). For example, the base plate 20 can use C30 grade concrete, and the reinforcing plate 30 can use high-strength concrete, which can improve the structural strength, durability, and crack resistance of the reinforcing plate 30. Specifically, the high-strength concrete can be C50 to C80 grade concrete prepared using cement, sand, stone, high-efficiency water-reducing agents, and mineral admixtures such as fly ash, ultrafine slag, and silica fume, and prepared using conventional processes. This can improve the load-bearing capacity and punching shear resistance of the plate-column structure. Furthermore, the performance of the reinforcing plate 30 can be further improved by incorporating high-ductility fibers into the high-strength concrete.

[0032] According to the modular slab-column structure system 100 of the present invention, by replacing the part of the floor slab connected to the supporting column 10 with a stronger reinforcing plate 30, the connection between the floor slab and the supporting column 10 can withstand greater shear force, and the punching shear resistance of the slab-column structure can be improved. It can also prevent the slab-column structure from being damaged by punching shear due to external loads, thereby improving the safety and reliability of the slab-column structure and reducing the safety hazards of the modular slab-column structure system 100.

[0033] like Figure 1 As shown, according to some embodiments of the present invention, the support column 10 may include a column body 11 and a plurality of first connecting ribs 12, the column body 11 being able to run along a first direction (e.g., Figure 1 Extending in the vertical direction (as shown), it can support the floor slab. At least a portion of the multiple first connecting bars 12 can be set inside the column body 11, and the first connecting bars 12 can extend along the first direction, which can improve the structural strength of the supporting column 10 and improve the support effect on the floor slab.

[0034] The plurality of first connecting ribs 12 can extend into the gap and be arranged in the reinforcing plate 30, which can improve the structural strength of the reinforcing plate 30, increase the contact area between the reinforcing plate 30 and the support column 10, and position the reinforcing plate 30, thereby improving the connection effect of the floor and the support column 10, allowing the connection between the floor and the support column 10 to withstand greater shear force, improving the shear resistance of the connection between the floor and the support column 10, preventing the connection between the floor and the support column 10 from being damaged by shear due to external loads on the modular slab-column structure system 100, improving the safety and reliability of the slab-column structure, and reducing the safety hazards of the modular slab-column structure system 100.

[0035] It can be understood that the plurality of first connecting ribs 21 can be vertical steel bars inside the support column 10, and a part of the vertical steel bars can extend to the outside of the support column 10 (such as the area reserved for pouring the reinforcing plate 30), which facilitates the connection of the support column 10 with its vertically adjacent modules (such as the reinforcing plate 30 or other support columns 10) in a wet lap joint (such as pouring concrete at the position of the protruding steel bars) to connect the support column 10 and the adjacent modules to form an integral whole, which has good connection effect and high structural strength, and is easy to operate.

[0036] As shown in Figure 1 In some embodiments, the reinforcing plate 30 can have a plurality of pre-holes (not shown in the figure), and the plurality of pre-holes can respectively extend in the first direction (such as the up-down direction as shown in Figure 1 The plurality of first connecting ribs 12 can be arranged in the plurality of pre-holes, which facilitates the connection of the reinforcing plate 30 and the support column 10, and allows the first connecting ribs 12 to correspond to the pre-pouring hole positions of the floor during the hoisting process of the floor, thereby positioning the installation of the floor and achieving rapid splicing of the slab-column structure, which is easy to operate.

[0037] After the first connecting rib 12 is arranged in the pre-pouring hole, the operator can inject grouting material into the pre-pouring hole (i.e., the gap between the first connecting rib 12 and the pre-hole), so that the reinforcing plate 30 can be connected to the support column 10 when the grouting material in the pre-pouring hole solidifies, the connection between the floor and the support column 10 can be achieved, and the grouting material solidified in the pre-pouring hole can fully wrap the part of the first connecting rib 12 located in the pre-pouring hole.

[0038] In this way, the grouting material solidified can increase the wrapping force of the first connecting rib 12, and improve the structural strength of the grouting material solidified, so that the connection between the floor and the support column 10 can withstand greater shear force, the shear resistance of the connection between the floor and the support column 10 can be improved, the safety and reliability of the slab-column structure can be improved, and the safety hazards of the modular slab-column structure system 100 can be reduced.

[0039] As shown in Figure 1 and Figure 1 According to some embodiments of the present application, the substrate 20 can include a plate body 21 and a plurality of second connecting ribs 22, at least a part of each second connecting rib 22 can be arranged in the plate body 21, the second connecting rib 22 can extend in a direction perpendicular to the first direction (such as a direction parallel to the horizontal plane), that is, the extension directions of the plurality of second connecting ribs 22 can be the same or different, and a part of the second connecting rib 22 can extend into the gap and be arranged in the reinforcing plate 30, which can improve the structural strength of the reinforcing plate 30, increase the contact area of the reinforcing plate 30 and the substrate 20, and limit the reinforcing plate 30, thereby improving the connection effect of the substrate 20 and the reinforcing plate 30, and improving the punching shear resistance of the connection between the floor slab and the support column 10, and improving the safety and reliability of the slab-column structure.

[0040] It can be understood that the plurality of second connecting ribs 22 can be horizontal steel bars inside the substrate 20, and a part of the horizontal steel bars can extend to the outside of the substrate 20 (such as a reserved area for pouring the reinforcing plate 30), which is beneficial to the connection between the substrate 20 and the module adjacent to it in the horizontal direction (such as the reinforcing plate 30 or other floor slabs), and the connection mode is wet lap joint (such as pouring concrete at the position of the protruding steel bar), so that the substrate 20 and the adjacent module are connected to form a whole, which has good connection effect and high structural strength, and is convenient to operate.

[0041] As shown in Figure 2 and Figure 1 In some embodiments, the plurality of second connecting ribs 22 can include a plurality of first ribs 221 and a plurality of second ribs 222, the plurality of first ribs 221 can be arranged at intervals in the second direction (such as the front-back direction as shown in Figure 2 , and the plurality of first ribs 221 can respectively extend in the third direction (such as the left-right direction as shown in Figure 1 , the plurality of second ribs 222 can be arranged at intervals in the third direction, and the plurality of second ribs 222 can respectively extend in the second direction, the first direction, the second direction and the third direction can be intersected two by two, that is, the first ribs 221 and the second ribs 222 with different extension directions can respectively extend into the gap and be arranged in the reinforcing plate 30.

[0042] Thus, the first connecting rib 12 and the second connecting rib 22 can be matched to simultaneously realize the limiting of the reinforcing plate 30 in multiple directions, which can improve the limiting effect of the reinforcing plate 30, improve the connecting effect of the base plate 20 and the reinforcing plate 30, improve the connecting effect of the reinforcing plate 30 and the support column 10, improve the safety and reliability of the connection of the floor slab and the support column 10 through the reinforcing plate 30, simultaneously disperse the stress of the reinforcing plate 30, so that the slab-column structure can bear force more uniformly, prevent the connection of the floor slab and the support column 10 from being damaged by punching shear due to the external load of the modular slab-column structure system 100, and improve the safety and reliability of the slab-column structure.

[0043] It can be understood that the first direction, the second direction and the third direction can be perpendicular to each other, which can improve the force transmission performance of the reinforcing plate 30 on the basis of ensuring the connection of the floor slab and the support column 10 through the reinforcing plate 30, can make the connection of the floor slab and the support column 10 bear greater shear force, prevent the connection of the floor slab and the support column 10 from being damaged by punching shear due to the external load of the modular slab-column structure system 100, improve the safety and reliability of the slab-column structure, and improve the force transmission performance of the slab-column structure, so that the slab-column structure can bear greater load.

[0044] As shown in Figure 1 and Figure 1 According to some embodiments of the present application, the modular slab-column structure system 100 can further include a plurality of walls, two adjacent walls can be connected by a support column 10, the support column 10 can have a first column body 111 and a second column body 112, the first column body 111 and the second column body 112 can respectively extend along a first direction (e.g., the up-down direction as shown in Figure 2 , and the first column body 111 and the second column body 112 can be arranged along a direction perpendicular to the first direction (e.g., a direction parallel to the horizontal plane), and the first column body 111 and the second column body 112 can be connected, which is beneficial to the prefabricated production of the support column 10.

[0045] The two adjacent walls can include a first wall 40 and a second wall 50, the first wall 40 can be connected with the first column body 111, and the first wall 40 and the first column body 111 can respectively extend along a second direction (e.g., the front-back direction as shown in Figure 1 in the cross section perpendicular to the first direction, the second wall 50 can be connected with the second column body 112, and the second wall 50 and the second column body 112 can respectively extend along a third direction (e.g., the left-right direction as shown in Figure 1 in the cross section perpendicular to the first direction.

[0046] The second direction and the third direction can intersect, so that the first wall body 40 and the second wall body 50 with different extension directions can be stressed in the same direction by the support column 10, the force transmission effect between the two adjacent wall bodies can be improved, the two wall bodies can be prevented from being damaged when the modular slab-column structure system 100 is subjected to a larger load or earthquake action, and the safety hazard of the modular slab-column structure system 100 can be reduced.

[0047] The reinforcing plate 30 can be connected with the first wall body 40 and the second wall body 50 respectively, on the basis of ensuring the connection of the reinforcing plate 30 and the support column 10, the limiting effect on the reinforcing plate 30 can be improved, the connection effect of the reinforcing plate 30 and the support column 10 can be improved, so that the connection between the floor slab and the support column 10 can bear a larger shear force, the punching shear performance of the slab-column structure can be improved, the punching shear damage of the slab-column structure due to the external load of the modular slab-column structure system 100 can be prevented, the safety and reliability of the slab-column structure can be improved, and the safety hazard of the modular slab-column structure system 100 can be reduced.

[0048] As shown in Figure 1 and Figure 1 in some embodiments, in the second direction (the front-rear direction as shown in Figure 2 , the length of the part of the reinforcing plate 30 for connecting with the first column body 111 and the first wall body 40 is L1, the length of the first column body 111 is L3, and in the first direction (the up-down direction as shown in Figure 2 , the thickness of the floor slab is L5, if the length of the part of the reinforcing plate 30 for connecting with the first column body 111 and the first wall body 40 is too small, the area of the part of the reinforcing plate 30 for connecting with the support column 10 is too small, and the punching shear performance of the slab-column structure is affected.

[0049] Therefore, the length of the part of the reinforcing plate 30 for connecting with the first column body 111 and the first wall body 40 can be limited to a range greater than or equal to the sum of the length of the first column body 111 and the thickness of the floor slab, i.e. L1≥L3+L5, the area of the part of the reinforcing plate 30 for connecting with the support column 10 can be increased, and the area of the part of the reinforcing plate 30 for connecting with the wall body can be increased, so that the connection between the floor slab and the support column 10 can bear a larger shear force, the punching shear performance of the slab-column structure can be improved, the punching shear damage of the slab-column structure due to the external load of the modular slab-column structure system 100 can be prevented, the safety and reliability of the slab-column structure can be improved, and the safety hazard of the modular slab-column structure system 100 can be reduced.

[0050] As shown in Figure 1 and Figure 1 in some embodiments, in the third direction (the left-right direction as shown in Figure 2The length of the part of the reinforcing plate 30 for connecting with the second column 112 and the second wall 50 in the first direction (e.g., the left-right direction) is L2, the length of the second column 112 is L4, and the thickness of the floor in the second direction (e.g., the up-down direction) is L5. Figure 2 The length of the part of the reinforcing plate 30 for connecting with the second column 112 and the second wall 50 in the first direction (e.g., the left-right direction) is L2, the length of the second column 112 is L4, and the thickness of the floor in the second direction (e.g., the up-down direction) is L5.

[0051] Therefore, the length of the part of the reinforcing plate 30 for connecting with the second column 112 and the second wall 50 can be limited to a range greater than or equal to the sum of the length of the second column 112 and the thickness of the floor, i.e., L2≥L4+L5, the area of the part of the reinforcing plate 30 for connecting with the support column 10 can be increased, and the area of the part of the reinforcing plate 30 for connecting with the wall can be increased, so that the connection between the floor and the support column 10 can withstand greater shear force, the shear resistance of the slab-column structure can be improved, the shear failure of the slab-column structure due to the external load of the modular slab-column structure system 100 can be prevented, the safety and reliability of the slab-column structure can be improved, and the safety hazard of the modular slab-column structure system 100 can be reduced.

[0052] As shown in Figure 1 and Figure 1 Figure 2 In some embodiments, the second direction and the third direction can be perpendicular, so that the two adjacent walls can be maximally stressed, the force transmission effect between the two adjacent walls can be improved, the cross section of the reinforcing plate 30 perpendicular to the first direction can be quadrangular, the connection between the reinforcing plate 30 and the wall can be facilitated based on ensuring that the floor is connected to the support column 10 through the reinforcing plate 30, the limiting effect of the reinforcing plate 30 can be improved, and the connection between the reinforcing plate 30 and the support column 10 can withstand greater shear force, the shear resistance of the slab-column structure can be improved, and the processing is facilitated.

[0053] According to some embodiments of the present application, the cross section of the reinforcing plate 30 perpendicular to the first direction can be rectangular, sector-shaped, L-shaped or other polygonal, the volume requirement of the reinforcing plate 30 can be reduced based on ensuring that the floor is connected to the support column 10 through the reinforcing plate 30, the production cost can be reduced, the cross section shape of the reinforcing plate 30 can be customized according to the mechanical requirements and space constraints in different building scenarios, the shear resistance, construction efficiency and structural adaptability of the slab-column connection joint can be ensured, and it can be understood that the central angle of the sector-shaped reinforcing plate 30 can be 90°, and one side of the arc of the sector-shaped reinforcing plate 30 can be connected to the floor slab 20.

[0054] In some embodiments, the wall can be a filled partition wall, which can realize the separation of the interior space of the modular slab-column structural system 100, and can be a force-bearing shear wall, which can bear the horizontal load and vertical load of the modular slab-column structural system 100, and can improve the bearing capacity and lateral displacement stiffness of the wall.

[0056] According to some embodiments of the present application, the base plate 20 and the reinforcing plate 30 can be integrally cast and formed, that is, during the casting and forming of the base plate 20, the operator can cast the reinforcing plate 30 into the gap with the second connecting rib 22, so that the casting of the base plate 20 and the casting of the reinforcing plate 30 can be carried out synchronously, which is beneficial to the combination of the contacted parts of the base plate 20 and the reinforcing plate 30, can improve the connection effect of the base plate 20 and the reinforcing plate 30, and can realize the prefabrication of the entire floor slab, which is convenient for operation.

[0057] Alternatively, the base plate 20 and the reinforcing plate 30 can be cast and formed successively, for example, the operator can first cast the base plate 20, and then cast the reinforcing plate 30 at the specified area (such as the area reserved for casting the reinforcing plate 30) outside the base plate 20, and the interface between the base plate 20 and the reinforcing plate 30 can be roughened (such as chiseling), that is, even if the base plate 20 and the reinforcing plate 30 are casted at the same time, the operator also needs to perform appropriate roughening treatment on the base plate 20 after initial setting and then immediately cast the reinforcing plate 30.
