Description

Technical Field

[0001] This invention relates to the field of steel-concrete composite building technology, specifically to a connection structure between a steel-concrete composite shear wall and a steel beam. Background Technology

[0002] Steel has advantages such as being lightweight, high-strength, ductile, and recyclable. Concrete itself has excellent mechanical compressive strength. Therefore, steel-concrete composite sections have good seismic performance and overall cost-effectiveness, and are widely used as vertical structural members (columns, shear walls).

[0003] When using steel-concrete composite section technology, the steel-concrete composite member requires internal transverse diaphragms to be installed at corresponding elevations on the upper and lower flanges (I-beams) of the steel beam (i.e., internal transverse diaphragms are installed inside the steel tube at corresponding elevations on the upper and lower flanges of the steel beam). This ensures safe and reliable force transfer between the rigidly connected steel beam and the steel-concrete composite member. To facilitate the pouring of concrete into the steel tube to form the steel-concrete composite section member, a concrete pouring hole (with a diameter of at least 150mm) must be left in the middle of the internal transverse diaphragm. The remaining internal transverse diaphragm after the pouring hole is opened must meet certain dimensional requirements to ensure the safety of force transmission at the rigid joint.

[0004] When using steel-concrete composite section technology in residential buildings, steel-concrete composite shear walls are used as vertical load-bearing members to address structural stiffness and indoor protruding column issues. However, due to the relatively small thickness of the shear wall, the size of the steel tubes within the steel-concrete composite shear wall is limited by the wall's thickness. Using internal transverse diaphragms cannot simultaneously meet the requirements for concrete pouring opening size and rigid node force transmission. To solve this problem, the internal transverse diaphragms of the steel tubes are currently eliminated to accommodate concrete pouring within them. Instead, external transverse diaphragms (also called outer ring plates, surrounding the outside of the steel tubes) are added at the corresponding elevations of the upper and lower flanges of the steel beams to complete the node force transmission. However, this results in the external transverse diaphragms protruding from the shear wall, affecting the interior functionality and aesthetics of the residence, significantly restricting the application of steel-concrete composite structure technology in residential buildings.

[0005] In addition, for ease of installation on site, the three-story steel pipe wall and column are usually lifted and installed as a whole at one time (each floor is about 3m high, and the total length of the three steel pipes is about 9m). If the method of setting internal horizontal diaphragms is adopted, the steel pipes need to be installed at the elevation of the steel beams on each floor. In actual production, the long steel pipes need to be cut into small sections of about 3m each, the internal horizontal diaphragms need to be welded, and then they need to be extended. This not only makes the production process complicated and greatly increases the processing cost, but also greatly increases the number of welds for re-extending the steel pipes, affecting the quality of the steel pipes. Summary of the Invention

[0006] The purpose of this invention is to provide a connection structure between a steel-concrete composite shear wall and a steel beam, which can not only smoothly complete the concrete pouring inside the steel pipe, but also ensure the safe transmission of internal forces at the connection node when the steel beam and the steel-concrete composite shear wall are rigidly connected without affecting the indoor use function and appearance quality of the residence.

[0007] The technical solution of this invention is:

[0008] A steel-concrete composite shear wall and steel beam connection structure includes a steel-concrete composite shear wall and a steel beam. The steel-concrete composite shear wall includes a steel pipe assembly and edge steel reinforcement columns. The steel pipe assembly includes steel pipes extending along the height direction of the steel-concrete composite shear wall, and concrete is poured into the steel pipes.

[0009] The edge steel columns and steel pipes are distributed along the length of the steel-concrete composite shear wall. The edge steel columns are fixed on the steel pipes. The edge steel columns include edge steel column flanges extending up and down along the height of the steel-concrete composite shear wall and edge steel column webs located between the edge steel column flanges and the steel pipes. The edge steel column flanges are parallel to the thickness direction of the steel-concrete composite shear wall.

[0010] The end of the steel beam is connected to the flange plate of the edge steel column. The edge steel column has a node area at the corresponding elevation position of the steel beam. The node area includes a node diaphragm located between the steel pipe and the flange plate of the edge steel column. The steel pipe, the flange plate of the edge steel column and the web of the edge steel column are all connected to the node diaphragm.

[0011] In this scheme, the dimensions of the steel tube concrete composite shear wall and steel beam connection structure do not protrude beyond the wall thickness of the steel tube concrete composite shear wall. The steel tube and edge steel column are prefabricated and welded together in the factory. The concrete inside the steel tube is smoothly poured into the cavity of the steel tube on the construction site, ultimately forming a steel tube concrete composite shear wall with edge steel column. Simultaneously, in conjunction with the node area, this ensures the safe transfer of internal forces at the connection node when the steel beam and steel tube concrete shear wall are rigidly connected, without affecting the interior functionality and aesthetic quality of the residence (the dimensions of the steel tube, edge steel column, and node diaphragm do not protrude beyond the wall thickness of the steel tube concrete composite shear wall). This eliminates the need for an internal diaphragm inside the steel tube to meet the concrete pouring requirements, and also solves the problem of external diaphragms affecting the interior functionality and aesthetic quality of the residence. This breakthrough overcomes the technical challenges of applying steel tube concrete shear walls in residential buildings.

[0012] On the other hand, compared with the existing technology that uses internal transverse diaphragms, which requires cutting the long steel pipe into smaller sections of about 3m, welding the internal transverse diaphragms, and then extending them, the steel pipe concrete composite shear wall and steel beam connection structure of this scheme does not require internal transverse diaphragms inside the steel pipe. Therefore, it can effectively reduce the steel pipe manufacturing process and the number of welds required to extend the steel pipe, which is conducive to improving the quality of the steel pipe and saving costs.

[0013] Preferably, the steel pipe has a rectangular cross-section, with its length aligned with the length of the steel-concrete composite shear wall, and its width equal to the thickness of the steel-concrete composite shear wall. This maximizes the cross-sectional dimensions of the steel pipe and the concrete cross-sectional area within it, while minimizing the wall length and reducing its impact on building functionality.

[0014] Preferably, the edge steel reinforcement column is located between the two wall surfaces of the steel-concrete composite shear wall in the thickness direction, so that the size of the edge steel reinforcement column does not protrude beyond the wall thickness range of the steel-concrete composite shear wall.

[0015] Preferably, the steel pipe is equipped with longitudinally extending baffles inside. This can improve the local stability of the steel pipe without affecting the concrete pouring requirements inside the pipe. In particular, when the steel pipe has a large dimension along the length of the wall, setting longitudinally extending baffles at certain intervals inside it can reduce the unsupported length of the steel pipe along the length of the wall and improve the local stability of the steel pipe.

[0016] Preferably, the node diaphragm includes an upper node diaphragm and a lower node diaphragm, and the steel beam includes an upper flange plate, a lower flange plate, and a web plate connecting the upper and lower flange plates. The upper node diaphragm and the upper flange plate of the steel beam are at the same height, and the lower node diaphragm and the lower flange plate of the steel beam are at the same height. This further improves the safety and efficiency of internal force transmission at the connection point between the steel pipe and the steel beam.

[0017] Preferably, the node region also includes a node reinforcement cover plate located between the steel pipe and the flange plate of the edge steel column. The node reinforcement cover plate connects the steel pipe and the flange plate of the edge steel column, and both the upper and lower transverse diaphragms of the node are connected to the node reinforcement cover plate. By adding a node reinforcement cover plate at the connection between the edge steel column and the steel beam, the local stress level of the steel plate near the connection node can be effectively reduced, ensuring the local safety of the structure. At the same time, the node reinforcement cover plate is located between the steel pipe and the flange plate of the edge steel column, and the node reinforcement cover plate does not protrude beyond the wall thickness range of the steel-concrete composite shear wall.

[0018] Preferably, the steel beam includes an upper flange plate, a lower flange plate, and a web plate connecting the upper and lower flange plates. The node reinforcement plates are vertically distributed and parallel to the length direction of the steel-concrete composite shear wall. The upper edge of the node reinforcement plate is located above the upper flange plate, and the lower edge is located below it. This further reduces the local stress level of the steel plate near the connection node, ensuring local structural safety.

[0019] Preferably, the steel beam includes an upper flange plate, a lower flange plate, and a web plate connecting the upper flange plate and the lower flange plate. A crossbeam is provided on the edge steel column flange plate at the position where it connects to the steel beam. The crossbeam is parallel to the web plate and is connected to the web plate by bolts. The upper flange plate and the lower flange plate are connected to the edge steel column flange plate by welds.

[0020] Preferably, the steel beam includes an upper flange plate, a lower flange plate, and a web plate connecting the upper and lower flange plates. A corbel beam is provided at the connection point between the edge steel column flange plate and the steel beam. The corbel beam includes an upper flange plate parallel to the upper flange plate, a lower flange plate parallel to the lower flange plate, and a web plate connecting the upper and lower flange plates. The web plate of the corbel beam is connected to the web plate of the steel beam by a connecting plate. The upper flange plate of the steel beam and the upper flange plate of the corbel beam are connected by a weld, and the lower flange plate of the steel beam and the lower flange plate of the corbel beam are connected by a weld.

[0021] Preferably, the edge steel reinforcement columns are made of T-shaped steel, I-shaped steel, or H-shaped steel, and the steel pipes are rectangular steel pipes that have been prefabricated in the factory. This greatly reduces the number of welds between the edge steel reinforcement columns and the rectangular steel pipe plates, increases processing convenience and product standardization, and thus reduces construction costs.

[0022] The beneficial effects of this invention are: it can smoothly complete the concrete pouring inside the steel pipe, and ensure the safe transmission of internal forces at the connection node when the steel beam and the steel pipe concrete shear wall are rigidly connected without affecting the indoor use function and appearance quality of the residence.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0036] Specific Implementation Example 1: As shown in the example Figure 1 , Figure 2 As shown, a steel-concrete composite shear wall and steel beam connection structure includes a steel-concrete composite shear wall 1 and a steel beam 2.

[0037] The steel-concrete composite shear wall 1 includes a steel pipe assembly 1.1 and edge steel reinforcement columns 1.2. The steel pipe assembly includes steel pipes 1.11 extending along the height direction of the steel-concrete composite shear wall. The inner cavity of the steel pipes forms a concrete pouring cavity for pouring concrete. In this embodiment, the steel pipes are vertically distributed. Concrete 1.3 is poured into the steel pipes.

[0038] The edge steel columns 1.2 and steel pipes 1.11 are distributed along the length of the steel-concrete composite shear wall. The edge steel columns are fixed to the steel pipes.

[0039] The edge steel columns are formed by welding T-shaped steel, I-shaped steel, H-shaped steel, or steel plates. The edge steel columns are vertically distributed, which helps to improve component standardization, enhance the level of industrialization in construction, reduce the impact of welds on steel properties, reduce the workload of welding and weld quality inspection, and lower construction costs. In this embodiment, the edge steel columns are T-shaped steel. The edge steel column 1.2 includes an edge steel column flange plate 1.21 extending vertically along the height direction of the steel-concrete composite shear wall and an edge steel column web plate 1.22 located between the edge steel column flange plate and the steel pipe. The edge steel column web plate is perpendicular to the edge steel column flange plate. The edge steel column flange plate is parallel to the thickness direction of the steel-concrete composite shear wall. The edge steel column is connected to the steel pipe by welds; specifically, the edge steel column web plate is connected to the steel pipe by welds.

[0040] The end of steel beam 2 is connected to the flange plate of the edge steel column. In this embodiment, the steel beam is an I-beam or H-beam, and includes an upper flange plate 2.1, a lower flange plate 2.2, and a web plate 2.3 connecting the upper and lower flange plates. The steel beams are horizontally distributed. The edge steel column has a node region 1.4 at the corresponding elevation of the steel beam. The node region includes a node diaphragm located between the steel pipe and the flange plate of the edge steel column. The steel pipe, the flange plate of the edge steel column, and the web plate of the edge steel column are all connected to the node diaphragm. Specifically, the steel pipe, the flange plate of the edge steel column, and the web plate of the edge steel column are all connected to the node diaphragm by welds, and the node diaphragm is horizontally distributed.

[0041] In this embodiment, the connection structure between the steel-concrete composite shear wall and the steel beam is such that the dimensions of the steel pipe, the edge steel column, and the node diaphragm of the joint area do not protrude beyond the wall thickness of the steel-concrete composite shear wall. The steel pipe and the edge steel column are prefabricated and welded together in the factory. There is no inner diaphragm in the concrete pouring cavity inside the steel pipe. The concrete inside the steel pipe is smoothly poured into the cavity of the steel pipe on the construction site, ultimately forming a steel-concrete composite shear wall with edge steel columns. At the same time, in conjunction with the joint area, it is possible to achieve safe transfer of internal forces at the connection joint without affecting the indoor use function and appearance quality of the residence when the steel beam and the steel-concrete composite shear wall are rigidly connected (the dimensions of the steel pipe, edge steel column, and node diaphragm of the joint area do not protrude beyond the wall thickness of the steel-concrete composite shear wall). In this way, it is not necessary to set an inner diaphragm inside the steel pipe to meet the concrete pouring requirements inside the steel pipe, and it can also solve the problem of affecting the indoor use function and appearance quality of the residence by setting an outer diaphragm around the outside of the steel pipe. This breakthrough has overcome the technical challenges of applying steel-concrete composite shear walls in residential buildings.

[0042] Specifically, such asFigure 1 , Figure 2 As shown, the edge steel frame column is located between the two wall surfaces of the steel-concrete composite shear wall in the thickness direction, so that the size of the edge steel frame column does not protrude beyond the wall thickness range of the steel-concrete composite shear wall.

[0043] like Figure 1 , Figure 2 As shown, in one embodiment of this example, there are two edge steel columns, and the steel pipe is located between the two edge steel columns; one edge steel column, the steel pipe and the other edge steel column are distributed along the length direction of the steel-concrete composite shear wall.

[0044] In another embodiment of this invention, there is one edge steel column, which is set on the steel beam connection side of the steel tube concrete composite shear wall.

[0045] The concrete inside the steel pipe is high-strength, non-shrink concrete. High-strength, non-shrink concrete further increases the work capacity of the concrete in the composite section, reducing steel usage and construction costs under the same stress level. Non-shrink concrete also improves the interoperability between the concrete and steel pipe components.

[0046] Furthermore, such as Figure 1 , Figure 2 As shown, the cross-section of steel pipe 1.11 is rectangular. The length direction of the steel pipe's cross-section is consistent with the length direction of the steel-concrete composite shear wall, and the width of the steel pipe's cross-section is the same as the thickness of the steel-concrete composite shear wall. This allows for maximizing the cross-sectional dimensions of the steel pipe and the concrete dimensions within the steel pipe in the steel-concrete composite shear wall, while minimizing the wall length and impacting the building's functionality.

[0047] Furthermore, such as Figure 1 , Figure 2 As shown, the steel pipe 1.11 is provided with vertically extending longitudinal partitions 1.12. These longitudinal partitions extend along the height direction of the steel-concrete composite shear wall. The longitudinal partitions are parallel to the thickness direction of the steel-concrete composite shear wall. There may be one or more longitudinal partitions; in this embodiment, there are two, which are distributed sequentially along the length direction of the steel-concrete composite shear wall. This improves the local stability of the steel pipe without affecting the concrete pouring requirements within it. In particular, when the steel pipe has a large dimension along the wall length, setting longitudinal partitions at certain intervals inside it can reduce the unsupported length of the steel pipe along the wall length, improve the local stability of the steel pipe, control the steel pipe wall thickness, and save costs.

[0048] In this embodiment, rectangular steel pipes manufactured using factory-rolled profiles are selected. This helps to improve component standardization, enhance the level of industrialization in construction, reduce weld seams between rectangular steel pipe plates, increase processing convenience and product standardization, thereby reducing construction costs.

[0049] Furthermore, such as Figure 1 , Figure 2 As shown, the node diaphragm includes an upper node diaphragm 1.41 and a lower node diaphragm 1.42. The upper node diaphragm is at the same height as the upper flange of the steel beam, and the lower node diaphragm is at the same height as the lower flange of the steel beam. This further improves the safe transmission of internal forces at the connection node between the steel pipe and the steel beam. In this embodiment, there are two upper node diaphragms, symmetrically distributed on both sides of the web of the edge steel column. There are also two lower node diaphragms, symmetrically distributed on both sides of the web of the edge steel column. The thickness of the upper node diaphragm is equal to that of the upper flange of the steel beam. The thickness of the lower node diaphragm is equal to that of the lower flange of the steel beam.

[0050] In this second specific embodiment, the remaining structure is the same as in the first specific embodiment, except that...

[0051] like Figure 3 , Figure 4 As shown, node domain 1.4 also includes a node reinforcing cover plate 1.43 located between the steel pipe and the flange plate of the edge steel column. The node reinforcing cover plate connects the steel pipe and the flange plate of the edge steel column, and both the upper and lower transverse diaphragms of the node are connected to the node reinforcing cover plate. In this embodiment, the node reinforcing cover plate is connected to the steel pipe by weld, and the node reinforcing cover plate is also connected to the flange plate of the edge steel column by weld. Both the upper and lower transverse diaphragms of the node are connected to the node reinforcing cover plate by weld. By adding a node reinforcing cover plate at the connection between the edge steel column and the steel beam, the local stress level of the steel plate near the connection node can be effectively reduced, ensuring the local safety of the structure. At the same time, the node reinforcing cover plate is located between the steel pipe and the flange plate of the edge steel column, and the node reinforcing cover plate does not protrude beyond the wall thickness range of the steel-concrete composite shear wall.

[0052] The node reinforcement cover plates are vertically distributed and parallel to the length direction of the steel-concrete composite shear wall. The upper edge of the node reinforcement cover plate is located above the upper flange of the steel beam; in actual use, the extent by which the upper edge of the node reinforcement cover plate extends beyond the upper flange of the steel beam is determined by calculation. The lower edge of the node reinforcement cover plate is located below the upper flange of the steel beam; in actual use, the extent by which the lower edge of the node reinforcement cover plate extends beyond the lower flange of the steel beam is determined by calculation.

[0053] The node reinforcement cover plate consists of two pieces, which are symmetrically distributed on both sides of the web of the edge steel column.

[0054] In this embodiment, the center of the node reinforcing cover plate and the center of the steel beam are at the same height in the height direction of the steel-concrete composite shear wall.

[0055] In this specific embodiment, the remaining structure is the same as in specific embodiment one or specific embodiment two, except that...

[0056] The steel beams and edge steel columns are rigidly connected; that is, the upper flange plate 2.1, lower flange plate 2.2, and web plate 2.3 of steel beam 2 are all welded to the flange plates of the edge steel columns. Specifically, on the construction site, the web plate of the steel beam is directly welded to the flange plate of the edge steel column using welds, while the upper and lower flange plates of the steel beam are connected to the flange plates of the edge steel column using equal-strength, full-penetration butt welds.

[0057] In this specific embodiment four, the remaining structure is the same as in specific embodiment one or specific embodiment two, except that...

[0058] like Figure 5 As shown, a crossbeam 3 is provided at the connection point between the edge steel column flange and the steel beam. The crossbeam is parallel to the web of the steel beam. The crossbeam is located between the upper and lower flanges of the steel beam. The crossbeam is bolted to the web of the steel beam; in this embodiment, friction-type high-strength bolts are used for the connection. The upper and lower flanges of the steel beam are welded to the edge steel column flange; in this embodiment, equal-strength, full-penetration butt welds are used for the connection.

[0059] In this specific embodiment, the remaining structure is the same as in specific embodiment one or specific embodiment two, except that...

[0060] like Figure 6 As shown, a corbel beam 4 is provided at the position where the edge steel column flange plate connects to the steel beam. In this embodiment, the corbel beam is an I-beam or H-beam, and includes an upper corbel beam 4.1 parallel to the upper flange plate of the steel beam, a lower corbel beam 4.2 parallel to the lower flange plate of the steel beam, and a corbel beam web 4.3 connecting the upper and lower flange plates of the corbel beam. The upper flange plate of the steel beam and the upper flange plate of the corbel beam are connected by welds, and the lower flange plate of the steel beam and the lower flange plate of the corbel beam are connected by welds. In this embodiment, the upper flange plate of the steel beam and the upper flange plate of the corbel beam, as well as the lower flange plate of the steel beam and the lower flange plate of the corbel beam, are connected using equal-strength full-penetration butt welds.

[0061] The web of the corbel beam is connected to the web of the steel beam via connecting plate 5. The connecting plate is bolted to the web of the corbel beam and to the web of the steel beam.

[0062] In one embodiment of this invention, the web of the corbel beam and the web of the steel beam are spliced ​​on one side by a connecting plate. The connecting plate is connected to the web of the corbel beam using friction-type high-strength bolts, and the connecting plate is connected to the web of the steel beam using friction-type high-strength bolts.

[0063] In another embodiment of this invention, the web of the corbel beam and the web of the steel beam are joined on both sides by two connecting plates, with the corbel beam web and the steel beam web located between the two connecting plates. The connecting plates are connected to the corbel beam web using friction-type high-strength bolts, and the connecting plates are also connected to the steel beam web using friction-type high-strength bolts.

[0064] In the figures of the above embodiments, the X-axis direction is the length direction of the steel-concrete composite shear wall, the Y-axis direction is the height direction of the steel-concrete composite shear wall, and the Z-axis direction is the thickness direction of the steel-concrete composite shear wall.

[0065] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications, alterations, and equivalent transformations made to the above embodiments based on the technical essence of the present invention shall still fall within the protection scope of the present invention.
