[0028] Reference is made below to Figure 1 - Figure 2 describe a modular slab-column structural system 100 according to an embodiment of the present invention.

[0029] As Figure 1 - Figure 2 shown, the modular slab-column structural system 100 according to an embodiment of the present invention includes: a floor slab and a plurality of support columns 10. The plurality of support columns 10 can extend respectively along a first direction (such as Figure 1 the up-and-down direction shown), and the floor slab can be installed on one side of the plurality of support columns 10 in the first direction (such as Figure 1 the upper side or the lower side shown). The floor slab can include a base plate 20 and a plurality of reinforcing plates 30. The edge of the base plate 20 has a plurality of notches, and the plurality of notches correspond to the plurality of support columns 10 one by one. 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 to the base plate 20.

[0030] The structural strength of the reinforcement 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 reinforcement plate 30, which can improve the structural strength of the connection part between the floor slab and the support column 10, enabling the connection between the floor slab and the support column 10 to bear greater shear force, improving the punching shear resistance of the connection between the floor slab and the support column 10, and preventing the connection between the floor slab and the support column 10 from being damaged by punching due to the modular slab-column structural system 100 being subjected to external loads. This can improve the safety and reliability of the slab-column structure (the connection structure formed by assembling the floor slab and the support column 10) and reduce the potential safety hazards of the modular slab-column structural system 100.

[0031] It can be understood that the base plate 20 can select the concrete type according to design requirements (concrete code, seismic code). For example, the base plate 20 can select C30-grade concrete, and the reinforcement plate 30 can select high-strength concrete, which can improve the structural strength of the reinforcement plate 30, enhance the durability of the reinforcement plate 30, and improve the crack resistance of the reinforcement plate 30. Specifically, the high-strength concrete can be C50 - C80-grade concrete prepared by using cement, sand, stone, superplasticizer and other admixtures, fly ash, ultrafine slag, silica fume and other mineral admixtures with conventional processes, which can improve the load-bearing capacity and punching shear resistance of the slab-column structure. Moreover, the high-strength concrete can be doped with high-ductility fibers to further enhance the performance of the reinforcement plate 30.

[0032] According to the modular slab-column structural system 100 of the embodiment of the present invention, by replacing the part of the floor slab connected to the support column 10 with a reinforcement plate 30 of higher strength, the connection between the floor slab and the support column 10 can bear greater shear force, improve the punching shear resistance of the slab-column structure, and prevent the slab-column structure from being damaged by punching due to the modular slab-column structural system 100 being subjected to external loads. Thus, the safety and reliability of the slab-column structure can be improved, and the potential safety hazards of the modular slab-column structural system 100 can be reduced.

[0033] As Figure 1 shown, according to some embodiments of the present invention, the support column 10 can include a column body 11 and a plurality of first connecting bars 12. The column body 11 can extend along a first direction (such as Figure 1 the up-and-down direction shown) to support the floor slab. At least a part of the plurality of first connecting bars 12 can be arranged 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 support column 10 and enhance the supporting effect on the floor slab.

[0034] Multiple first connecting ribs 12 can extend into the notch and pass through the reinforcement plate 30, which can improve the structural strength of the reinforcement plate 30, increase the contact area between the reinforcement plate 30 and the support column 10, and can realize the limit of the reinforcement plate 30, thereby improving the connection effect between the floor slab and the support column 10, enabling the connection between the floor slab and the support column 10 to withstand greater shear force, improving the punching shear resistance at the connection between the floor slab and the support column 10, preventing punching shear failure at the connection between the floor slab and the support column 10 due to the modular slab-column structure system 100 being subjected to external loads, improving the safety and reliability of the slab-column structure, and reducing the potential safety hazards of the modular slab-column structure system 100.

[0035] It can be understood that multiple first connecting ribs 21 can be the 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 reserving an area for pouring the reinforcement plate 30), which is beneficial to the connection between the support column 10 and the adjacent module in the vertical direction (such as the reinforcement plate 30 or other support columns 10), and the connection method is wet lapping (such as pouring concrete at the position where the steel bars extend out), so that the support column 10 and the adjacent module are connected to form an integral body, with good connection effect and high structural strength, and it is convenient to operate at the same time.

[0036] Such as Figure 1 As shown, in some embodiments, the reinforcement plate 30 can have multiple preset holes (not shown in the figure), and the multiple preset holes can extend along the first direction (such as Figure 1 the up and down direction shown), and the multiple preset holes and the multiple first connecting ribs 12 can correspond one by one, and the multiple first connecting ribs 12 can pass through the multiple preset holes respectively, which is beneficial to realizing the connection between the reinforcement plate 30 and the support column 10, and enabling the first connecting ribs 12 to correspond to the positions of the preset holes of the reinforcement plate 30 during the hoisting process of the floor slab, realizing the positioning of the floor slab installation, thereby realizing the rapid splicing of the slab-column structure and being convenient to operate.

[0037] Wherein, after the first connecting rib 12 passes through the preset hole, the operator can inject grouting material into the preset hole (that is, the gap between the first connecting rib 12 and the preset hole), so that the reinforcement plate 30 can be connected to the support column 10 when the grouting material in the preset hole solidifies, realizing the connection between the floor slab and the support column 10, and the solidified grouting material in the preset hole can fully wrap the part of the first connecting rib 12 located in the preset hole.

[0038] Thus, the grip force of the solidified grouting material on the first connecting rib 12 can be increased, and the structural strength of the solidified grouting material can be improved, enabling the connection between the floor slab and the support column 10 to withstand greater shear force, improving the punching shear resistance at the connection between the floor slab and the support column 10, improving the safety and reliability of the slab-column structure, and reducing the potential safety hazards of the modular slab-column structure system 100.

[0039] As Figure 1 and Figure 2 shown, according to some embodiments of the present invention, the substrate 20 may include a plate body 21 and a plurality of second connecting ribs 22. At least a part of each second connecting rib 22 may be disposed within the plate body 21. The second connecting ribs 22 may extend in a direction perpendicular to the first direction (such as a direction parallel to the horizontal plane), that is, the extending directions of the plurality of second connecting ribs 22 may be the same or different, and a part of the second connecting rib 22 may extend into the notch and penetrate through 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 substrate 20, and can achieve the limit of the reinforcing plate 30, thereby improving the connection effect between the substrate 20 and the reinforcing plate 30, and improving the punching shear resistance at 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 may be horizontal steel bars inside the substrate 20, and a part of the horizontal steel bars may extend to the outside of the substrate 20 (such as reserving an area for pouring the reinforcing plate 30), which is beneficial to the connection between the substrate 20 and the modules adjacent to it in the horizontal direction (such as the reinforcing plate 30 or other floor slabs), and the connection method is wet lapping (such as pouring concrete at the part where the steel bars protrude) to connect the substrate 20 and the adjacent modules to form an integral body, with good connection effect and high structural strength, and convenient operation at the same time.

[0041] As Figure 1 and Figure 2 shown, in some embodiments, the plurality of second connecting ribs 22 may include a plurality of first ribs 221 and a plurality of second ribs 222. The plurality of first ribs 221 may be arranged at intervals in the second direction (such as the front-back direction shown in Figure 1 ), and the plurality of first ribs 221 may respectively extend in the third direction (such as the left-right direction shown in Figure 1 ). The plurality of second ribs 222 may be arranged at intervals in the third direction, and the plurality of second ribs 222 may respectively extend in the second direction. The first direction, the second direction, and the third direction may intersect pairwise, that is, the first ribs 221 and the second ribs 222 with different extending directions may respectively extend into the notch and penetrate through the reinforcing plate 30.

[0042] Thus, the first connecting rib 12 and the second connecting rib 22 can cooperate to limit the reinforcing plate 30 simultaneously in multiple directions, improving the limiting effect on the reinforcing plate 30, enhancing the connection effect between the base plate 20 and the reinforcing plate 30, and improving the connection effect between the reinforcing plate 30 and the support column 10. This can enhance the safety and reliability of the floor slab connected to the support column 10 through the reinforcing plate 30. Meanwhile, the stress of the reinforcing plate 30 can be dispersed, enabling the slab-column structure to be more evenly stressed, preventing punching failure at the connection between the floor slab and the support column 10 due to the modular slab-column structure system 100 being subjected to external loads, and improving 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 pairwise. On the basis of ensuring the connection between the floor slab and the support column 10 through the reinforcing plate 30, the force transmission performance of the reinforcing plate 30 can be improved, enabling the connection between the floor slab and the support column 10 to withstand greater shear force, and preventing punching failure at the connection between the floor slab and the support column 10 due to the modular slab-column structure system 100 being subjected to external loads. This can improve the safety and reliability of the slab-column structure, and at the same time improve the force transmission performance of the slab-column structure, enabling the slab-column structure to bear greater loads.

[0044] As Figure 1 and Figure 2 shown, according to some embodiments of the present invention, the modular slab-column structure system 100 may further include multiple walls. Two adjacent walls can be connected through the support column 10. The support column 10 may have a first column body 111 and a second column body 112. The first column body 111 and the second column body 112 can extend respectively along the first direction (such as the up-down direction shown in Figure 1 ), and the first column body 111 and the second column body 112 can be arranged in a direction perpendicular to the first direction (such as 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] Two adjacent walls may include a first wall 40 and a second wall 50. The first wall 40 can be connected to the first column body 111, and in a cross-section perpendicular to the first direction, the first wall 40 and the first column body 111 can extend respectively along the second direction (such as the front-back direction shown in Figure 1 ), the second wall 50 can be connected to the second column body 112, and in a cross-section perpendicular to the first direction, the second wall 50 and the second column body 112 can extend respectively along the third direction (such as the left-right direction shown in Figure 1 ).

[0046] The second direction and the third direction can intersect, such that the first wall 40 and the second wall 50 with different extending directions can be stressed against each other in the same direction through the support column 10, which can improve the force transmission effect between two adjacent walls, prevent the two walls from being damaged when the modular slab-column structure system 100 is subjected to a large load or seismic action, and reduce the potential safety hazards of the modular slab-column structure system 100.

[0047] The strengthening plates 30 can be respectively connected to the first wall 40 and the second wall 50. On the basis of ensuring the connection between the strengthening plates 30 and the support column 10, the limiting effect on the strengthening plates 30 can be improved, the connection effect between the strengthening plates 30 and the support column 10 can be enhanced, so that the connection between the floor slab and the support column 10 can bear greater shear force, the punching shear resistance of the slab-column structure can be improved, and the slab-column structure can be prevented from being damaged by punching due to the modular slab-column structure system 100 being subjected to external loads, which can improve the safety and reliability of the slab-column structure and reduce the potential safety hazards of the modular slab-column structure system 100.

[0048] As Figure 1 and Figure 2 shown, in some embodiments, in the second direction (such as the front-back direction shown in Figure 2 ), the length of the part of the strengthening plate 30 for connecting with the first column 111 and the first wall 40 is L1, the length of the first column 111 is L3, and in the first direction (such as the up-down direction shown in Figure 1 ), the thickness of the floor slab is L5. If the length of the part of the strengthening plate 30 for connecting with the first column 111 and the first wall 40 is too small, the area of the part of the strengthening plate 30 for connecting with the support column 10 is too small, which affects the punching shear resistance of the slab-column structure.

[0049] Therefore, the length of the part of the strengthening plate 30 for connecting with the first column 111 and the first wall 40 can be limited to a range greater than or equal to the sum of the length of the first column 111 and the thickness of the floor slab, that is, L1≥L3 + L5, which can increase the area of the part of the strengthening plate 30 for connecting with the support column 10 and increase the area of the part of the strengthening plate 30 for connecting with the wall, so that the connection between the floor slab and the support column 10 can bear greater shear force, improve the punching shear resistance of the slab-column structure, prevent the slab-column structure from being damaged by punching due to the modular slab-column structure system 100 being subjected to external loads, thereby improving the safety and reliability of the slab-column structure and reducing the potential safety hazards of the modular slab-column structure system 100.

[0050] As Figure 1 and Figure 2 shown, in some embodiments, in the third direction (such as Figure 2In the left - right direction (as shown), the length of the portion of the reinforcing plate 30 for connecting to the second column 112 and the second wall 50 is L2, the length of the second column 112 is L4, and in the first direction (such as Figure 1 the up - down direction as shown), the thickness of the floor slab is L5. If the length of the portion of the reinforcing plate 30 for connecting to the second column 112 and the second wall 50 is too small, the area of the portion of the reinforcing plate 30 for connecting to the support column 10 is too small, affecting the punching shear resistance of the slab - column structure.

[0051] Therefore, the length of the portion of the reinforcing plate 30 for connecting to 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 slab, that is, L2≥L4 + L5. This can increase the area of the portion of the reinforcing plate 30 for connecting to the support column 10, and can also increase the area of the portion of the reinforcing plate 30 for connecting to the wall, so that the connection between the floor slab and the support column 10 can bear greater shear force, improving the punching shear resistance of the slab - column structure, preventing the slab - column structure from punching failure due to the modular slab - column structure system 100 being subjected to external loads, thereby improving the safety and reliability of the slab - column structure, and reducing the potential safety hazards of the modular slab - column structure system 100.

[0052] Such as Figure 1 and Figure 2 shown, in some embodiments, the second direction and the third direction can be perpendicular to each other, so that adjacent two walls can exert force on each other to the greatest extent, improving the force - transmission effect between adjacent two walls. And the cross - section of the reinforcing plate 30 perpendicular to the first direction can be a quadrilateral. On the basis of ensuring that the floor slab is connected to the support column 10 through the reinforcing plate 30, it is beneficial for the connection between the reinforcing plate 30 and the wall, improving the limiting effect on the reinforcing plate 30, and enabling the connection between the reinforcing plate 30 and the support column 10 to bear greater shear force, improving the punching shear resistance of the slab - column structure, and being convenient for processing at the same time.

[0053] According to some embodiments of the present invention, the cross - section of the reinforcing plate 30 perpendicular to the first direction can be a rectangle, a sector, an L - shape or other polygons. On the basis of ensuring that the floor slab is connected to the support column 10 through the reinforcing plate 30, the volume requirement of the reinforcing plate 30 can be reduced, the production cost can be reduced, and at the same time, the cross - section shape of the reinforcing plate 30 can be customized according to the mechanical requirements and space constraints in different building scenarios, ensuring the punching shear resistance, construction efficiency and structural adaptability of the slab - column connection node. It can be understood that the central angle of the above - mentioned sector can be 90°, and one side of the arc of the sector - shaped reinforcing plate 30 can be connected to the base plate 20.

[0054] In some embodiments, the wall can be a partition wall, which can achieve the partitioning of the internal space of the modular slab-column structure system 100. The wall can be a load-bearing shear wall, which can bear the horizontal load and vertical load of the modular slab-column structure system 100, and can improve the bearing capacity and lateral displacement resistance stiffness of the wall.

[0055] In some embodiments, the first connecting bar 12 and the second connecting bar 22 can be steel bars respectively. The steel bars can be made of materials such as ordinary carbon steel bars, high-strength steel bars, stainless steel bars or composite material bars, which can adapt to different mechanical property requirements and durability requirements. Moreover, the steel bars can be hot-rolled ribbed steel bars, cold-rolled ribbed steel bars or precision rolled threaded steel bars, etc., which can meet the requirements of different connection strengths and mechanical properties. Further, the steel bars can adopt surface treatment methods such as smooth surface, threaded surface or coating treatment, which can improve the bonding performance and corrosion resistance between the steel bars and the grouting material.

[0056] According to some embodiments of the present invention, the base plate 20 and the reinforcement plate 30 can be integrally cast. That is, during the casting process of the base plate 20, the operator can pour the reinforcement plate 30 into the notch with the second connecting bar 22, so that the casting of the base plate 20 and the casting of the reinforcement plate 30 can be carried out synchronously, which is beneficial to the combination of the contacting parts of the base plate 20 and the reinforcement plate 30, can improve the connection effect between the base plate 20 and the reinforcement 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 reinforcement plate 30 can be cast successively. For example, the operator can first cast the base plate 20, and then cast the reinforcement plate 30 in a designated area outside the base plate 20 (such as a reserved area for casting the reinforcement plate 30), and the interface between the base plate 20 and the reinforcement plate 30 can be roughened (such as chiseling). Even if the base plate 20 and the reinforcement plate 30 are cast simultaneously, the operator also needs to first perform appropriate roughening treatment on the base plate 20 after initial setting and then immediately cast the reinforcement plate 30.

[0058] According to some embodiments of the present invention, multiple components (such as walls and support columns 10) in the modular slab-column structure system 100 can be connected by mechanical connection or chemical bonding, etc. Mechanical connection can use connecting parts such as sleeves or bolts to tightly connect the precast components together, with fast construction speed and high construction efficiency. Chemical bonding can use adhesives or special cementitious materials to firmly bond the connecting parts of the components together, with good durability and shear resistance at the joints. In addition, multiple components in the modular slab-column structure system 100 can be prefabricated in the factory and then spliced on the construction site, which can save costs, improve construction efficiency, reduce the wet operation amount of on-site construction, and at the same time can meet the requirements of different building designs, and can improve the adaptability and variability of the modular slab-column structure system 100.

[0059] Other components and operations of the modular slab-column structure system 100 according to the embodiments of the present invention are known to those of ordinary skill in the art and will not be described in detail herein. In the description of the present invention, "the first feature" and "the second feature" may include one or more of such features. Among them, the up-down direction, left-right direction, and front-back direction are based on the up-down direction, left-right direction, and front-back direction shown in the figure.
