Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a steel-concrete frame modular building with an integrated beam-column structure. Background Technology

[0002] Prefabricated buildings, with their short construction cycles and minimal environmental impact, have become an important development direction for achieving green building and industrialization. Among prefabricated buildings, modular buildings, with the highest assembly rate and degree of industrialization, are a key path for the transformation and upgrading of the construction industry. Among various modular building systems, the frame structure system, due to its flexible layout and wide applicability, is widely used in various types of buildings such as commercial podiums, hospitals, and schools. Currently, among existing frame-system modular buildings, concrete frame and steel frame structures have been developed earlier and are more widely used, but their use presents the following significant problems:

[0003] In modular concrete frame buildings, joints are typically connected using pre-reinforced steel bars and post-cast concrete. While this method ensures a certain degree of integrity, it involves a large amount of on-site wet work, making it difficult to control construction quality and resulting in a long curing period, severely limiting the core advantages of modular buildings. Furthermore, the heavy weight and large cross-sectional dimensions of concrete components increase the difficulty and cost of transportation and hoisting, thus restricting their application in high-rise buildings.

[0004] Modular steel-frame buildings primarily rely on bolts for module connections. While this method offers convenient assembly, it suffers from significant shortcomings in joint performance: First, the tensile strength of the joints often depends entirely on the bolts, resulting in limited capacity and poor ductility, making it difficult to meet the stringent tensile requirements of high-rise buildings under wind loads or seismic action. Second, these joints are typically treated as hinged connections, failing to effectively transfer bending moments, leading to insufficient overall lateral stiffness of the structure and hindering the full utilization of the steel column's own sectional stiffness in the lateral force resisting system. Finally, in steel structures, adjacent modules' columns can only be designed as independent columns under compression, failing to form composite sections, resulting in poor buckling stability and underutilization of material strength.

[0005] A steel-concrete frame structure is a modular system that combines steel frames with concrete, using concrete to reinforce the steel frame. However, in existing steel-concrete frame technologies, the hybrid structure is mostly only incorporated within the modules to achieve synergy. At key connection nodes between modules, traditional steel-bolt connections are often used, with the concrete serving only as filler and auxiliary fixation, and its ability to transfer bending and tensile forces remains insufficient. Furthermore, in floor systems formed by multi-layered modules, adjacent floor slabs (at the floor level) between different modules cannot function as a unified whole for permanent use (the beams at the top of the frame structure bear less stress), resulting in poor overall shear resistance of the modular building and causing structural bulk and material waste.

[0006] Therefore, there is an urgent need for a new type of modular steel-concrete frame composite structure system that can effectively solve the connection technology problems of steel-concrete composite structures in modular buildings, improve the overall load-bearing capacity and stiffness of the structure, and meet the dual requirements of high-rise buildings for structural safety and economy. Utility Model Content

[0008] In view of the above-mentioned shortcomings and deficiencies of the existing technology, this utility model provides a steel-concrete frame modular building with an integrated beam-column structure, which solves the technical problems of insufficient tensile and bending bearing capacity of the connection nodes between modules, poor column compressive stability, and low shear resistance of the modular building in the existing modular frame building.

[0009] (II) Technical Solution

[0010] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0011] In a first aspect, this utility model provides a steel-concrete frame modular building with an integrated beam-column structure, comprising at least three integrated building modules; each integrated building module includes several frame columns and several frame beams; the several frame columns include at least one of first component columns and second component columns; the several frame beams include at least one of upper frame beams and lower frame beams.

[0012] Both the first and second component columns are provided with grouting grooves extending along their length, and slots are provided on their side walls; the slots of the first and second component columns are respectively provided with mounting grooves and mounting guide rails; the first and second component columns on two horizontally adjacent integrated building modules can be assembled into an integrated column connecting component by slidingly inserting their respective mounting grooves and mounting guide rails along the length, and the grouting grooves of the two are connected through the slots to form an integrated grouting channel;

[0013] Shear keys and sleeves are provided on the top of the upper frame beam and the lower frame beam, respectively; the lower shear key of the two adjacent integrated building modules is inserted vertically into the upper sleeve to form an integrated beam connection component.

[0014] Optionally, the integrated grouting channel is reinforced with longitudinal steel bars and filled with concrete; the integrated beam connection component is also filled with concrete.

[0015] Optionally, the integrated grouting channels in two adjacent integrated building modules correspond one-to-one and are interconnected; the longitudinal steel bars in each integrated grouting channel extend to the integrated grouting channel of the corresponding integrated building module at its top and / or bottom.

[0016] Optionally, in two adjacent integrated building modules, the upper frame beam on the lower integrated building module corresponds one-to-one with the lower frame beam on the upper integrated building module; the bottom of the sleeve protrudes from the bottom of the lower frame beam and abuts against the top of the upper frame beam; the upper frame beam, the lower frame beam, and the integrated beam connecting member form a hollow truss.

[0017] Optionally, a single integrated building module may have only a first component column or a second component column.

[0018] Optionally, the first or second component column is located on the edge and / or side of the integrated building module adjacent to other integrated building modules; the upper frame beam and the lower frame beam are located at the edge of the integrated building module adjacent to other integrated building modules.

[0019] Optionally, the mounting slot and mounting guide rail are arranged in pairs on both sides of the slot opening.

[0020] Optionally, the sleeve includes a first expanding cylinder, a straight cylinder, and a second expanding cylinder connected sequentially from bottom to top; the straight cylinder has a cylindrical or prismatic structure; the first and second expanding cylinders both have a frustum-shaped or prismatic structure.

[0023] (III) Beneficial Effects

[0024] The beneficial effects of this utility model are as follows: This utility model provides a modular steel-concrete frame building with an integrated beam-column structure. By using a first component column and a second component column to form an integrated column connection component, and by creating an integrated grouting channel through the grouting grooves in the first and second component columns, this utility model's steel-concrete structure, compared to existing technologies, can form a flawless, continuous composite column at the connection point of the integrated building modules. Under compression, the stability of this composite column can be verified as a whole cross-section. Its moment of inertia and radius of gyration are much larger than those of a single independent column or a steel-concrete composite column with interruptions, thus significantly improving the compressive bearing capacity and buckling stability of the columns in the modular building. While achieving rigid connection at column joints, it avoids defects such as weak tensile and bending resistance, and can meet the stringent requirements of special buildings such as high-rise buildings. Meanwhile, this utility model also features an integrated beam connection component in the longitudinal direction. By inserting the shear key of the upper frame beam of the lower integrated building module into the sleeve of the lower frame beam of the upper integrated building module, a reliable shear connection interface is formed. In the permanent stage, this connection, combined with concrete pouring, can effectively transfer vertical shear force, making the integrated building modules of different floors form a whole at the floor slab, thereby significantly enhancing the building's ability to resist horizontal shear loads vertically.

Detailed Implementation

[0043] To better explain and facilitate understanding of this utility model, a detailed description of its specific embodiments is provided below with reference to the accompanying drawings. In this document, directional terms such as "upper," "lower," "left," "right," "front," and "rear" are used interchangeably with other directional terms. Figure 1 The orientation is used as a reference.

[0044] Example 1

[0045] Reference Figure 1 and Figure 2 This embodiment provides a steel-concrete frame modular building with an integrated beam-column structure, comprising at least three integrated building modules. Each integrated building module includes several frame columns and several frame beams. The frame beams and frame columns are connected by conventional methods such as bolts to form the main frame structure of the integrated building module in this embodiment, or the main load-bearing structure of the integrated building module. This provides a stable foundation for subsequent component structures in the integrated building module (such as floor slabs, pipes, wall panels, etc., which need to be installed on the basis of the main frame structure to form a complete integrated building module. These component structures can be installed according to actual needs and will not be described in detail in this embodiment) and connection processes, and ensures the structural integrity of the integrated building module during hoisting, transportation, and use.

[0046] Depending on the design requirements, the integrated building modules can be various structures such as conventional cuboids, cubes, or unconventional trapezoids, as long as they can be assembled into a building. In this embodiment, for example... Figure 1-2 As shown, a conventional rectangular parallelepiped structure is preferred, with the integrated building module comprising 4 frame columns and 8 frame beams. This standardized 4-column, 8-beam rectangular parallelepiped module structure facilitates mass production and refined manufacturing in factories, significantly controlling quality and reducing costs. Furthermore, providing a uniform basic unit for the construction site accelerates the assembly and combination of modular buildings.

[0047] In actual construction, three or more integrated building modules of any number can be combined and expanded in both horizontal (left-right and front-back) and vertical (up-down) dimensions to form a modular building. It is important to note that with only two integrated building modules, expansion is limited to either the horizontal or vertical direction; while with only three integrated building modules, expansion in both directions is possible, the resulting modular building cannot form an effective grid structure, failing to fully utilize the integrated beam-column structure of this embodiment. Therefore, more preferably, the modular building includes at least four integrated building modules, forming a 2×2 or larger grid structure (grid system) to maximize the effectiveness of the integrated beam-column structure of this embodiment. (Refer to...) Figure 1 In this embodiment, specifically, a modular building (2×2) comprising two layers of integrated building modules is constructed. Each layer has two modular buildings: the first layer has a first integrated building module 1 and a second integrated building module 2, and the second layer has a third integrated building module 3 and a fourth integrated building module 4, for a total of four integrated building modules. The third integrated building module 3 is located on top of the first integrated building module 1, and the fourth integrated building module 4 is located on top of the second integrated building module 2.

[0048] In this embodiment, refer to Figure 1 In this embodiment, integrated column connecting members 5 are provided between adjacent horizontally arranged integrated building modules to connect two adjacent horizontally arranged (generally horizontally arranged) integrated building modules. Integrated beam connecting members 6 are provided between adjacent vertically arranged integrated building modules to connect two vertically arranged (generally vertically arranged) integrated building modules. Specifically, in this embodiment, integrated column connecting members 5 are provided between the first integrated building module 1 and the second integrated building module 2, and between the third integrated building module 3 and the fourth integrated building module 4. Integrated beam connecting members 6 are provided between the first integrated building module 1 and the third integrated building module 3, and between the second integrated building module 2 and the fourth integrated building module 4. After the integrated column connecting members 5 and the integrated beam connecting members 6 are formed, an integrated beam-column structure is created in the modular building, enabling integrated and coordinated connection of different integrated building modules. This allows horizontal loads (such as wind and earthquake loads) and vertical loads to be efficiently transferred and distributed within the integrated building modules on the same floor and across different floors through the integrated beam-column structure, thereby improving the building's load-bearing capacity and lateral stiffness.

[0049] In this embodiment, as Figure 3As shown, the frame columns include at least one of a first component column 7 and a second component column 8. The first component column 7 or the second component column 8 is disposed at the edge and / or side of the integrated building module adjacent to other integrated building modules, preferably at the edge. It should be noted that the first component column 7 and the second component column 8 should be avoided on frame columns or other column structures inside or outside the integrated building module that are not adjacent to other integrated building modules. This reduces the number, types, and locations of such special component columns, simplifying the production and installation process and reducing costs while ensuring the strength of the integrated building module and meeting the connection requirements between modules.

[0050] Furthermore, the specific integrated building module may contain only the first component column 7 or the second component column 8, or both, and the exact location and quantity of the first component column 7 and / or the second component column 8 can be modified according to design requirements. This ensures that during modular building construction, the first component column 7 and the second component column 8 can correspond one-to-one and connect to form an integrated column connecting component 5 at adjacent points of two horizontally arranged integrated building modules. For example, in this embodiment, when using rectangular integrated building modules to construct a 2×2 modular building, the first integrated building module 1 is only adjacent to the second integrated building module 2 in the horizontal direction. The first integrated building module 1 only has the first component column 7 at the two edges adjacent to the second integrated building module 2. In this case, the second component column 8 is correspondingly placed at the two edges of the second integrated building module 2 at the same location as the first integrated building module 1.

[0051] In this embodiment, a single integrated building module is provided with only the first component column 7 or the second component column 8. This approach simplifies the types of integrated building modules from the production source, ensuring that when manufacturing any integrated building module, the same production line only needs to process a single type of component column. This greatly reduces confusion and error rates during the production process, thereby improving the production efficiency and product quality consistency of integrated building modules.

[0052] In this embodiment, as Figure 4 As shown, the frame beams include at least one of upper frame beams 15 and lower frame beams 16. The upper frame beams 15 and lower frame beams 16 on different integrated building modules are connected to form an integrated beam connection member 6. The upper frame beams 15 and lower frame beams 16 are located on the sides of the integrated building module adjacent to other integrated building modules, preferably at the edges of the sides. The integrated beam connection member 6 is integrated at the edge of the main structure of the module, and it works together with the component columns to unify the main stress points on the edge line of the integrated building module. This ensures that the force and displacement coordination between all integrated building modules occurs at clearly defined boundaries, collectively forming a complete and efficient spatial stress grid.

[0053] In a specific integrated building module, whether it only has an upper frame beam 15 or a lower frame beam 16, or both, and the specific location and number of the upper frame beam 15 and / or lower frame beam 16, can be modified according to design requirements. The goal is to ensure that during modular building construction, at adjacent points between two longitudinally arranged integrated building modules, the upper frame beam 15 and lower frame beam 16 correspond one-to-one, with the upper frame beam 15 positioned below the lower frame beam 16, allowing for grouting and connection to form an integrated beam connection component 6. Specifically, in this embodiment, when using rectangular integrated building modules to construct a 2×2 modular building, the first integrated building module 1 is only adjacent to the third integrated building module 3 in the longitudinal direction, and the third integrated building module 3 is positioned on top of the first integrated building module 1. The first integrated building module 1 only has upper frame beams 15 at its four top edges adjacent to the third integrated building module 3. At this time, the lower frame beams 16 are positioned at the four bottom edges of the third integrated building module 3, corresponding to the first integrated building module 1.

[0054] In this embodiment, the first component column 7, the second component column 8, the upper frame beam 15, and the lower frame beam 16 are all integral parts of the integrated building module's frame structure. When subjected to stress, the force flow is direct, smooth, and without weak transition points, resulting in significantly higher structural reliability than methods that add external connectors later. Furthermore, by avoiding the use of additional connecting plates and other auxiliary steel materials, the integrated building module achieves better overall integrity, possessing higher rigidity and strength during hoisting and transportation, while also saving steel, reducing material costs and structural weight.

[0055] like Figure 3 As shown, both the first component column 7 and the second component column 8 are provided with grouting grooves 9 that extend through their axial direction. In other words, the first component column 7 and the second component column 8 are hollow columnar structures with openings at both ends, and their grouting grooves 9 (the hollow parts) extend along their length for subsequent pouring of concrete 24. On the side walls of the first component column 7 and the second component column 8, slots 10 are provided along their axial direction, forming C-shaped or U-shaped groove structures with both ends of the grouting groove 9. The slots 10 of the first component column 7 and the second component column 8 are respectively provided with mounting grooves 11 and mounting guide rails 12. The grouting groove 9 provides sufficient space for subsequent accommodating of the post-cast concrete 24 and reinforcing bars. The axially set slot 10 provides an installation interface for the mounting groove 11 and the mounting guide rail 12. At the same time, it also ensures that after the first component column 7 and the second component column 8 are connected, the internal space of the grouting groove 9 is completely connected and there is no obstruction between them, ensuring that they can form an integrated steel-concrete composite column without any interruption during subsequent grouting.

[0056] In this embodiment, as Figure 3-4 As shown, a mounting groove 11 is provided at the slot 10 of the first component column 7, and a mounting guide rail 12 is provided at the slot 10 of the second component column 8. The mounting guide rail 12 is an eave-like structure formed by the protrusion of the grooves on both sides of the slot 10 of the second component column 8. The mounting groove 11 is a groove-like structure formed by the protrusion and bending of the side walls on both sides of the slot 10 of the first component column 7. The mounting groove 11 and the mounting guide rail 12 are arranged in pairs on both sides of the slot. The mounting guide rail 12 can only slide into the mounting groove 11 along the end of the mounting groove 11 and slide along the mounting groove 11, so that the mounting groove 11 and the mounting guide rail 12 form a self-locking structure. The first component column 7 and the second component column 8 on different integrated building modules can be slidably inserted along the length direction through their respective mounting slots 11 and mounting guide rails 12, thereby forming an integrated column connecting component 5, and connecting (or enclosing) the grouting grooves 9 of the first component column 7 and the second component column 8 to form an integrated grouting channel 13. For example... Figure 5-6 As shown, the integrated grouting channel 13 is equipped with longitudinal steel bars 14 and filled with concrete (post-cast concrete 24).

[0057] When the first component column 7 and the second component column 8 on two different integrated building modules form a self-locking structure through the mounting groove 11 and the mounting guide rail 12, their respective grooves 10 connect to form a closed (more precisely, a sealed cross-sectional shape), continuous integrated grouting channel 13. The two ends of the integrated grouting channel 13 are connected, allowing for grouting and communication with other integrated grouting channels 13. After the integrated grouting channel 13 is formed, the previously independent first component column 7 and the second component column 8 can structurally form a single, continuous concrete casting. After the post-cast concrete 24 is poured, the integrated grouting channel 13 is filled together with the longitudinal reinforcing steel 14, and the first component column 7 and the second component column 8 are permanently connected by the concrete. Reinforced concrete possesses high tensile strength and ductility. When used for connection, compared to the fragile bolt connections in traditional steel or reinforced concrete modules, it improves the mechanical properties of the column connection nodes (integrated column connection member 5) in this embodiment of the integrated building module. This allows it to safely withstand the large tensile forces generated by wind loads or earthquakes in high-rise buildings and exhibits excellent seismic ductility. Simultaneously, the concrete and longitudinal reinforcement 14, as well as the first and second component columns 8, are tightly integrated into a single unit, forming an integrated column connection member 5 (which can be understood as a composite column) with a continuous, defect-free reinforced concrete composite cross-section at the node. It should be noted that, since the integrated grouting channel 13 lacks partitions or other structures, the concrete and longitudinal reinforcement 14 can physically and mechanically fuse the horizontally adjacent first and second component columns 7 and 8 into a single, uninterrupted composite column with a large overall cross-section. When performing compressive stability calculations, this composite column has a large continuous cross-sectional area. Its moment of inertia and radius of gyration are much larger than those of composite columns using traditional connection methods such as bolts or steel-concrete composite columns with concrete filling and connection and intermediate partitions. Its buckling critical load can be increased by more than an order of magnitude, thereby significantly improving the column's compressive bearing capacity and stability.

[0058] The integrated column connection member 5 in this embodiment not only has extremely high bearing capacity, but also can efficiently transmit bending moment through the steel reinforcement structure therein. While realizing rigid connection between modules, it integrates discrete module units into an overall spatial grid frame with strong lateral stiffness.

[0059] Meanwhile, since the integrated connection structure of this embodiment has high strength and load-bearing capacity, the cross-section of the steel column can be further reduced under the same load-bearing capacity requirements, thereby reducing the amount of steel used and lowering costs.

[0060] Meanwhile, by setting the mounting slot 11 and mounting guide rail 12, two horizontally adjacent integrated building modules can be quickly aligned and spliced ​​during the splicing process using the mounting slot 11 and mounting guide rail 12. The splicing process is fast, accurate and requires no complicated adjustments, which can greatly improve construction efficiency and reliability, and achieve efficient assembly.

[0061] In addition, the self-locking structure formed by the mounting groove 11 and the mounting guide rail 12 also has a certain fixing capacity, which can restrict the relative movement of the first component column 7 and the second component column 8. While acting as a permanent template, it also bears temporary loads, effectively resists wind loads and accidental impacts during the construction stage, provides a certain initial stiffness and stability before grouting, provides a safe and stable working platform for subsequent grouting operations, and provides an additional certain ability to resist lateral forces after grouting.

[0062] like Figure 7 As shown, when multiple integrated building modules are arranged vertically, the integrated grouting channels 13 in the integrated building modules of different layers correspond one-to-one and are interconnected. The longitudinal steel bars 14 in each integrated grouting channel 13 extend to the integrated grouting channel 13 of the corresponding integrated building module at its top and / or bottom.

[0063] Specifically, in this embodiment, the top of the longitudinal steel bar 14 in the integrated grouting channel 13 at the connection between the first integrated building module 1 and the second integrated building module 2 extends into the integrated grouting channel 13 at the connection between the third integrated building module 3 and the fourth integrated building module 4, forming an integrated structure.

[0064] In this way, by vertically connecting the integrated grouting channels 13 on the integrated building modules of different floors in the modular building and connecting the vertical steel bars 14 to the adjacent integrated grouting channels 13, a defect-free steel-concrete composite column system from the base to the top floor is formed in the final modular building. The base building units of different floors are connected to form a complete whole, avoiding the discrete stress of the longitudinally set base building modules, so that the effect of force transmission between columns is similar to that of cast-in-place structure.

[0065] The longitudinal reinforcement 14 can be installed using a conventional steel cage structure or other interwoven structures. In the permanent use configuration, the pressure and bending moment borne by the modular building can be borne by the combined columns, and the column tension between the upper and lower modules can be further transferred through the longitudinal reinforcement 14. The specific interweaving density, diameter, and connection methods of the longitudinal reinforcement 14 in the upper and lower integrated building modules are not detailed in this embodiment.

[0066] Furthermore, when setting up multi-layer integrated building modules and grouting, it is understood that it is necessary to set sealing structures such as sealant at the bottom of the integrated grouting channel 13 of the bottommost integrated building module and on the outside of the connection between two integrated grouting channels 13 to prevent leakage of the subsequent concrete 24 during grouting. The description of such grouting operations and other methods will not be repeated in this embodiment.

[0067] In this embodiment, as Figure 1-2 As shown, the integrated building module also includes auxiliary frame columns 17 and auxiliary frame beams 18. The auxiliary frame beams 18 and auxiliary frame columns 17 can be conventional column or beam structures. The auxiliary frame columns 17 may also be equipped with grouting grooves 9 and longitudinal reinforcing bars 14 installed in accordance with the integrated column connection method, followed by the pouring of post-cast concrete 24. This connects the corresponding auxiliary frame columns 17 in different integrated building modules on different floors to form a whole, further enhancing the structural strength of the modular building in this embodiment.

[0068] In the integrated building module of this embodiment, the frame beams and frame columns that are not adjacent to other integrated building modules can all be auxiliary frame beams 18 and auxiliary frame columns 17. In the integrated building module, if the module is located at the top / bottom / edge of the modular building, some of its frame beams / frame columns do not need to be connected to other frame beams / frame columns. In this case, conventional frame beams and frame columns can be used as substitutes to reduce the use of customized components (such as the first component column 7, the second component column 8, etc.) and reduce costs.

[0069] In this embodiment, as Figure 8-9 As shown, a shear key 19 is provided at the top of the upper frame beam 15. A sleeve 20 is provided at the lower frame beam 16. When the integrated building modules are arranged longitudinally, in two adjacent integrated building modules, the shear key 19 on the lower integrated building module is inserted vertically into the sleeve 20 on the upper integrated building module to form an integrated beam connection member 6. The integrated beam connection member 6 is also filled with concrete (post-cast concrete 24). The shear key 19 and the sleeve 20 are connected by the post-cast concrete 24, thereby connecting the upper frame beam 15 and the lower frame beam 16.

[0070] In this modular building, the shear key 19 and sleeve 20 work together to connect adjacent frame beams in two longitudinally arranged integrated building modules, forming an integrated beam connection component 6 (which can be understood as a composite beam). This allows the frame beams of the upper integrated building module to directly transfer the loads and lateral forces they receive to the frame beams of the lower integrated building module through the sleeve 20, avoiding the situation where the frame beams at the top of the building modules are idle, as is the case in traditional modules. In a permanent state, the integrated beam connection component 6 can bear gravity loads and horizontal loads as a whole. The frame beams in the upper and lower integrated building modules work together, making full use of the material strength of the frame beams, maximizing material utilization, significantly improving economy, and saving costs. In addition, the combination of shear key 19 and sleeve 20 can also be used with the first component column 7 and the second component column 8 during construction to achieve rapid plug-in installation between different integrated building modules, providing precise positioning and initial fixing points for the upper and lower modules.

[0071] In this embodiment, when multiple integrated building modules are arranged vertically, the upper frame beam 15 on the lower integrated building module corresponds one-to-one with the lower frame beam 16 on the upper integrated building module. For example... Figure 9 As shown, the bottom of the sleeve 20 protrudes from the bottom of the lower frame beam 16 and abuts against the top of the upper frame beam 15, so that there is a certain gap between the upper frame beam 15 and the lower frame beam 16, thereby forming a hollow truss with the upper frame beam 15, the lower frame beam 16 and the integrated beam connecting member 6.

[0072] Among them, the lower frame beam 16 is the upper chord of the open-web truss, and the upper frame beam 15 is the lower chord of the open-web truss. The two work together to resist bending moment. The sleeve 20 is the web member of the open-web truss, which can effectively resist shear force and further improve the synergistic effect between the upper frame beam 15 and the lower frame beam 16.

[0073] In this embodiment, the shear key 19 is a stud, T-shaped steel, Y-shaped steel, H-shaped steel, or channel steel that is wider at the top and narrower at the bottom. The contour and structure of these shear keys 19 increase the contact surface and interlocking area between the shear key 19 and the concrete, enabling the transmission of greater longitudinal shear force. This further prevents horizontal slippage between the structural beams of different integrated building modules, ensuring that the formed open-web truss can work collaboratively as a robust whole.

[0074] In this embodiment, the sleeve 20 can be a cylindrical, square, or other cylindrical through-structure that passes through the lower frame beam 16, and can accommodate the shear key 19 by filling it with concrete.

[0075] In this embodiment, the frame columns, frame beams, shear keys 19, and sleeves 20 are all steel structures.

[0076] When assembling the modular building of this embodiment, the following method can be used, S1: as follows Figure 10 As shown, first assemble the first layer of integrated building modules, that is, assemble the first integrated building module 1 and the second integrated building module 2. S2: As shown Figure 11 As shown, longitudinal reinforcing bars 14 are provided in the integrated column connection member 5 and the auxiliary frame column 17. S3: As shown Figure 12 As shown, concrete is filled into the integrated column connecting member 5 and the auxiliary frame column 17 in the first floor. S4: As shown Figure 13 As shown, a second integrated building module, a third integrated building module 3, and a fourth integrated building module 4 are spliced ​​onto the first integrated building module. S5: Concrete is filled into the integrated beam connecting member 6 between the first and second layers. S6: As shown... Figure 14-15 As shown, longitudinal steel bars 14 are installed in the integrated column connecting member 5 and the auxiliary frame column 17 of the second layer and filled with concrete. The structure is then capped and decorated to obtain the modular building of this embodiment.

[0077] Example 2

[0078] Reference Figure 3 This embodiment provides a modular steel-concrete frame building with an integrated beam-column structure. The difference from Embodiment 1 is that the sleeve 20 includes a first expanding cylinder 21, a straight cylinder 22, and a second expanding cylinder 23 connected sequentially from bottom to top. The straight cylinder 22 is a cylindrical or prismatic structure; in this embodiment, a cylindrical structure is preferred. Both the first expanding cylinder 21 and the second expanding cylinder 23 are frustum-shaped or prismatic structures, and their cross-sectional diameters gradually increase along the axis of the straight cylinder 22. When the upper frame beam 15 and lower frame beam 16 on different integrated building modules are connected, the widest point of the shear key 19 passes sequentially through the first expanding cylinder 21 and the straight cylinder 22 and enters the second expanding cylinder 23, with the first expanding cylinder 21 abutting against the upper frame beam 15.

[0079] The first expanding cylinder 21, with its circular / frustum-shaped structure, provides tolerance space for the positioning of the shear key 19 during installation and assists in the alignment between the first component column 7 and the second component column 8, ensuring smooth entry even with hoisting deviations and reducing construction difficulty. The second expanding cylinder 23 at the bottom interlocks with the wider portion of the shear key 19, resulting in a strong mechanical interlocking effect between the conical inner wall of its frustum / frustum, the widest part of the shear key 19, and the concrete after concrete pouring. This forms a stable bearing and load-bearing contact surface, ensuring reliable transmission of vertical loads between frame beams and further enhancing the pull-out resistance and shear bearing capacity of the integrated beam connection component 6.

[0080] The diameter of the straight cylinder 22 is slightly larger than the width of the widest part of the shear key 19, ensuring that the shear key 19 can pass through the straight cylinder 22 and that the concrete can completely fill the first expanding cylinder 21 through the gap between the straight cylinder 22 and the shear key 19. In this embodiment, the diameter of the straight cylinder 22 is preferably 1-2 cm larger than the width of the widest part of the shear key 19, and the distance from the widest part of the shear key 19 to the top of the straight cylinder 22 is not less than 3 cm. By selecting a suitable aperture for the straight cylinder 22, the positioning effect of the first expanding cylinder 21 is ensured, while ensuring that the shear key 19 can pass through the straight cylinder 22 section without obstruction, preventing installation jamming, and ensuring that the concrete can flow and fill densely.

[0081] Example 3

[0082] Reference Figure 3 This embodiment provides a modular steel-concrete frame building with an integrated beam-column structure. The difference from Embodiment 1 is that this modular building includes eight integrated building modules, with four integrated building modules on each floor. The first floor includes modules C1, D1, E1, and F1 arranged from left to right. Module C1 has two first component columns 7 only at its connection with module D1, and module D1 has only second component columns 8 on both sides connecting to modules C1 and E1. Module E1 has only first component columns 7 on both sides connecting to modules D1 and F1, and module F1 has only a second component column 8 on one side connecting to module E1. The second floor includes modules C2, D2, E2, and F2 arranged from left to right. Module C2 has two second component columns 8 only at its connection with module D2, and module D2 has only first component columns 7 on both sides connecting to modules C2 and E2. Module E2 is connected to modules D2 and F2, with only second component columns 8 on both sides. Module F2 is connected to module E2, with only first component columns 7 on both sides. It should be noted that in integrated building modules of different floors, the first component columns 7 and the second component columns 8 do not need to correspond one-to-one. Their connection forms the integrated grouting channels 13 in the integrated column connecting component 5, which can correspond one-to-one and form a connected structure for grouting to form a complete steel-concrete composite column with vertical connection.
