Abstract
Description
Technical Field
[0001] This application relates to the field of building construction technology, and more specifically, to a beam-column connection component and a steel-concrete composite structure. Background Technology
[0002] Traditionally, the connection between steel-concrete composite columns and reinforced concrete beams typically involves two methods: welding steel sleeves to the steel column or welding steel brackets to the steel column. However, directly welding the steel sleeves to the steel column and mechanically connecting the steel bars to the sleeves is cumbersome and inefficient because the ends of the steel bars in the same span cannot be simultaneously mechanically connected to the sleeves. The steel bars must be split into two sections and connected to the sleeves at each end, then welded or lapped in the beam. Welding steel brackets to the steel column usually involves welding steel plates at the top and bottom of the beam corresponding to the steel column, and then welding the longitudinal reinforcement to the plates. This method is more convenient. However, in actual engineering projects, due to the requirements of span and load-bearing capacity, reinforced concrete beams generally have large spans and high load-bearing capacities, necessitating double-layer reinforcement at the top and bottom of the beam. Using existing conventional methods, the double-layer reinforcement results in limited welding space, making the operation difficult and compromising connection quality.
[0003] Therefore, how to improve the ease of connection between large-span reinforced concrete beams and steel-concrete composite columns has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content
[0004] In view of this, the purpose of this application is to provide a beam-column connection assembly to improve the convenience of connection between large-span reinforced concrete beams and steel-concrete composite columns.
[0005] Another objective of this application is to provide a steel-concrete composite structure employing the aforementioned beam-column connection components.
[0006] To achieve the above objectives, this application provides the following technical solution:
[0007] A beam-column connection assembly, comprising:
[0008] The connecting component body includes two flange plate assemblies, which are fixed to the steel sections of the steel-concrete column and distributed along the height direction of the steel sections. The two flange plate assemblies are respectively used to connect with the top longitudinal reinforcement and the bottom longitudinal reinforcement of the reinforced concrete beam. Each flange plate assembly includes at least two flange plates, and each flange plate is respectively used to connect with each row of top longitudinal reinforcement or bottom longitudinal reinforcement. The length of each flange plate in each flange plate assembly increases sequentially from top to bottom along the longitudinal direction of the reinforced concrete beam, so that a connecting space for connecting the top longitudinal reinforcement or the bottom longitudinal reinforcement is formed between two adjacent flange plates of each flange plate assembly.
[0009] Optionally, in the above-mentioned beam-column connection assembly, the connection assembly body further includes a web plate connected between the two flange plate assemblies, and the width of the web plate is not greater than the length of the uppermost flange plate of each flange plate assembly along the longitudinal direction of the reinforced concrete beam.
[0010] Optionally, in the above-mentioned beam-column connection assembly, the web is provided with stirrup pre-reserved holes along the height direction of the steel-concrete column for passing through the stirrups inside the steel-concrete column.
[0011] Optionally, in the above-mentioned beam-column connection assembly, each flange plate of each flange plate assembly is provided with a reserved hole or groove for the longitudinal reinforcing bars of the steel-concrete column to pass through.
[0012] Optionally, in the above beam-column connection assembly, each flange plate assembly includes an upper flange plate and a lower flange plate, the lower flange plate is located below the upper flange plate, and the upper flange plate has the steel bar reserved groove, and the lower flange plate has the steel bar reserved hole corresponding to the steel bar reserved groove.
[0013] Optionally, in the above-mentioned beam-column connection assembly, the reserved groove for the reinforcing bar extends from the edge of the upper flange away from the steel section toward the side closer to the steel section.
[0014] Optionally, in the above-mentioned beam-column connection assembly, the reserved holes for the reinforcing bars are elongated holes, and at least a portion of the reserved holes for the reinforcing bars coincide with the reserved grooves for the reinforcing bars.
[0015] Optionally, in the above-mentioned beam-column connection assembly, the connection assembly body further includes a stiffening rib adapted to the flange plate assembly, the stiffening rib being disposed on the steel section and facing away from the flange plate assembly.
[0016] A steel-concrete composite structure includes steel-concrete composite columns, reinforced concrete beams, and connecting components, wherein the connecting components are used to connect the steel-concrete composite columns and the reinforced concrete beams, and the connecting components are beam-column connecting components as described in any of the preceding claims.
[0017] Optionally, in the above-mentioned steel-concrete composite structure, the steel-concrete composite column includes box-shaped steel and reinforced concrete covering the outside of the box-shaped steel, and the steel-concrete composite column is connected to a plurality of the reinforced concrete beams, and the connecting assembly is fixed to the outer wall of the box-shaped steel and adapted to the reinforced concrete beams.
[0018] The beam-column connection assembly provided in this application fixes two flange plate assemblies along the height direction of the steel section in the steel-concrete composite column. Each flange plate assembly can connect to the top and bottom longitudinal reinforcement bars in the reinforced concrete beam, respectively. Furthermore, each flange plate assembly has at least two flange plates, allowing each flange plate to be connected to either the top or bottom longitudinal reinforcement bars of its respective row. The length of each flange plate in each flange plate assembly increases sequentially from top to bottom along the longitudinal direction of the reinforced concrete beam, creating a connection space between adjacent flange plates of each flange plate assembly that facilitates the connection of the top or bottom longitudinal reinforcement bars. This allows for the convenient fixing of each row of top and bottom longitudinal reinforcement bars to the flange plates of the two flange plate assemblies. As can be seen from the above examples, the beam-column connection assembly provided in this application, by setting flange plates of different lengths on the steel section to connect with the top longitudinal reinforcement and bottom longitudinal reinforcement of each row of reinforced concrete beams, forms a connection space between two adjacent flange plates of each flange plate assembly, which facilitates the connection of the top longitudinal reinforcement or the bottom longitudinal reinforcement. This facilitates the connection of the flange plate with the top longitudinal reinforcement or the bottom longitudinal reinforcement by welding, thereby improving the convenience of the connection between large-span reinforced concrete beams and steel-concrete columns.

[0031] The core of this application is to provide a beam-column connection component to improve the ease of connection between large-span reinforced concrete beams and steel-concrete composite columns.
[0032] Another core aspect of this application is to provide a steel-concrete composite structure employing the aforementioned beam-column connection components, thereby improving the ease of connection between large-span reinforced concrete beams and steel-concrete composite columns.
[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0034] Steel-concrete composite members integrate steel profiles and reinforced concrete cladding to form a unified load-bearing structure. Compared to ordinary concrete members, this improves the shear and bending resistance of the member, making it widely used in high-rise buildings and long-span structures. One common connection point in structures using steel-concrete composite members is the connection between steel-concrete composite columns and reinforced concrete beams. The reliability and ease of construction of these connections are key factors influencing the development of steel-concrete composite structures.
[0035] Traditionally, the connection between steel-concrete composite columns and reinforced concrete beams typically involves two methods: welding steel sleeves to the steel column or welding steel brackets to the steel column. However, directly welding the steel sleeves to the steel column and mechanically connecting the steel bars to the sleeves is cumbersome and inefficient because the ends of the steel bars in the same span cannot be simultaneously mechanically connected to the sleeves. The steel bars must be split into two sections and connected to the sleeves at each end, then welded or lapped in the beam. Welding steel brackets to the steel column usually involves welding steel plates at the top and bottom of the beam corresponding to the steel column, and then welding the longitudinal reinforcement to the plates. This method is more convenient. However, in actual engineering projects, due to the requirements of span and load-bearing capacity, reinforced concrete beams generally have large spans and high load-bearing capacities, necessitating double-layer reinforcement at the top and bottom of the beam. Using existing conventional methods, the double-layer reinforcement results in limited welding space, making the operation difficult and compromising connection quality.
[0036] Therefore, such as Figure 1 As shown in the figure, this application discloses a beam-column connection assembly, including a connection assembly body 100. By providing flange plates 11 of different lengths on the steel profile 201, which are respectively connected to the top longitudinal steel bars 301 and bottom longitudinal steel bars 302 of each row of reinforced concrete beam 300, a connection space 12 is formed between two adjacent flange plates 11 of each flange plate assembly 10, which facilitates the connection of the top longitudinal steel bars 301 or the bottom longitudinal steel bars 302. This facilitates the welding connection between the flange plate 11 and the top longitudinal steel bars 301 or the bottom longitudinal steel bars 302, improving the convenience of the connection between the large-span reinforced concrete beam 300 and the steel-concrete column 200.
[0037] The following will combine Figures 1 to 5 The beam-column connection components disclosed in the embodiments of this application will be explained and described in detail.
[0038] like Figure 1 and Figure 2As shown, the connecting component body 100 may include two flange plate assemblies 10, and the two flange plate assemblies 10 may be welded to the steel section 201 of the steel-concrete column 200, and distributed along the height direction of the steel section 201. The two flange plate assemblies 10 may be welded and fixed to the top longitudinal reinforcement 301 and the bottom longitudinal reinforcement 302 of the reinforced concrete beam 300, respectively, to achieve a reliable connection between the steel-concrete column 200 and the reinforced concrete beam 300, and ensure the stability of force transmission. Each flange plate assembly 10 may include at least two flange plates 11, that is, the number of flange plates 11 may be two or more, so that each flange plate 11 can be welded to each row of top longitudinal reinforcement 301 or bottom longitudinal reinforcement 302. Meanwhile, as... Figure 2 As shown, the length of each flange plate 11 of each flange plate assembly 10 along the longitudinal direction of the reinforced concrete beam 300, that is, the length of each flange plate 11 of each flange plate assembly 10 perpendicular to the steel section 201, increases sequentially from top to bottom. This creates a connection space 12 between two adjacent flange plates 11 of each flange plate assembly 10, which facilitates the welding of the top longitudinal steel bars 301 or the bottom longitudinal steel bars 302. This allows for easy welding of each row of top longitudinal steel bars 301 and bottom longitudinal steel bars 302 to the flange plates 11 of the two flange plate assemblies 10, improving the convenience of connecting the double rows of longitudinal steel bars of the large-span reinforced concrete beam 300 with the steel-concrete column 200, making construction more convenient and improving construction efficiency.
[0039] In some embodiments, such as Figure 3 As shown, for ease of understanding, the flange plate assembly 10 connected to the top longitudinal reinforcement 301 of the reinforced concrete beam 300 is defined as the upper flange plate assembly 13, and the flange plate assembly 10 connected to the bottom longitudinal reinforcement 302 of the reinforced concrete beam 300 is defined as the lower flange plate assembly 14. Each flange plate assembly 10 may include two flange plates 11. The upper flange plate 11 of each flange plate assembly 10 is defined as the upper flange plate 113, and the lower flange plate 11 of each flange plate assembly 10 is defined as the lower flange plate 114. The length of the upper flange plate 113 along the longitudinal direction of the reinforced concrete beam 300 (i.e., perpendicular to the steel section 201) is less than the length of the lower flange plate 114 along the longitudinal direction of the reinforced concrete beam 300, thus forming a connection space 12 between the upper flange plate 113 and the lower flange plate 114 that facilitates welding. Figure 2As shown. When connecting the steel-concrete column 200 and the reinforced concrete beam 300, the top longitudinal steel bars 301 of the lower layer of the reinforced concrete beam 300 can be welded to the welding area of the lower flange plate 114 of the upper flange plate assembly 13 that is larger than the upper flange plate 113. Simultaneously, the top longitudinal steel bars 301 of the upper layer of the reinforced concrete beam 300 can be welded to the upper flange plate 113 of the upper flange plate assembly 13. At the same time, the bottom longitudinal steel bars 302 of the lower layer of the reinforced concrete beam 300 can be welded to the welding area of the lower flange plate 114 of the lower flange plate assembly 14 that is larger than the upper flange plate 113. And the bottom longitudinal steel bars 302 of the upper layer of the reinforced concrete beam 300 can be welded to the upper flange plate 113 of the lower flange plate assembly 14. Figure 3 As shown, this ensures a large connection area between the double rows of longitudinal steel bars at the top and bottom of the reinforced concrete beam 300 and the beam-column connection assembly of the steel-concrete column 200, thereby achieving a reliable connection between the steel-concrete column 200 and the reinforced concrete beam 300 and ensuring the stability of force transmission.
[0040] It should be noted that the number of flanges 11 in each flange assembly 10 may be, but is not limited to, two in the above embodiment, or three or more, and the length of each flange 11 along the longitudinal direction of the reinforced concrete beam 300 increases sequentially from top to bottom, so as to accommodate the connection of three or more rows of longitudinal steel bars at the top and bottom of the reinforced concrete beam 300.
[0041] The beam-column connection assembly disclosed in this application comprises two flange plate assemblies 10 fixed along the height direction of the steel section 201 in the steel-concrete column 200. The two flange plate assemblies 10 can respectively connect to the top longitudinal reinforcement 301 and the bottom longitudinal reinforcement 302 in the reinforced concrete beam 300. Simultaneously, each flange plate assembly 10 has at least two flange plates 11, allowing each flange plate 11 to be connected to each row of top longitudinal reinforcement 301 or bottom longitudinal reinforcement 302. The length of each flange plate 11 in each flange plate assembly 10 increases sequentially from top to bottom along the longitudinal direction of the reinforced concrete beam 300, forming a connection space 12 between adjacent flange plates 11 of each flange plate assembly 10, facilitating the connection of the top longitudinal reinforcement 301 or the bottom longitudinal reinforcement 302. This facilitates the fixing of each row of top longitudinal reinforcement 301 and bottom longitudinal reinforcement 302 to the flange plates 11 of the two flange plate assemblies 10.
[0042] The beam-column connection assembly disclosed in this application provides flange plates 11 of different lengths on the steel profile 201, which are respectively connected to the top longitudinal steel bars 301 and bottom longitudinal steel bars 302 of each row of reinforced concrete beam 300. This creates a connection space 12 between two adjacent flange plates 11 of each flange plate assembly 10, which facilitates the connection of the top longitudinal steel bars 301 or the bottom longitudinal steel bars 302. This allows for easy welding connection between the flange plates 11 and the top longitudinal steel bars 301 or the bottom longitudinal steel bars 302, effectively solving the problem of not being able to guarantee the welding quality when there are double layers of longitudinal steel bars in the reinforced concrete beam 300, and improving the convenience of connection between the large-span reinforced concrete beam 300 and the steel-concrete column 200.
[0043] In some embodiments, such as Figures 1 to 3 As shown, the connecting assembly body 100 may further include a web 20, which is perpendicular to the two flange plate assemblies 10 and connects the two flange plate assemblies 10 to improve the stability and strength of the connecting assembly body 100. Meanwhile, the width of the web 20 is not greater than the length of the uppermost flange plate 11 (i.e., the upper flange plate 113) along the longitudinal direction of the reinforced concrete beam 300 in each flange plate assembly 10. Figure 2 As shown, while meeting the strength requirements, the web 20 is flush with the shortest flange 11 connecting the longitudinal reinforcement of the reinforced concrete beam 300, which further facilitates the welding of the longitudinal reinforcement of the reinforced concrete beam 300 and the pouring of concrete.
[0044] In some embodiments, such as Figure 2 As shown, multiple stirrup pre-drilled holes 21, which can pass through the stirrups of the steel-concrete composite column 200, can be spaced apart on the web 20 along the height direction of the column 200. There can be two, three, four, or more stirrup pre-drilled holes 21 to facilitate the installation of stirrups in the core area of the nodes within the steel-concrete composite column 200, ensuring the strength and integrity of the column 200. It should be noted that the number of stirrup pre-drilled holes 21 can be determined based on the number of stirrups in the core area of the nodes within the steel-concrete composite column 200.
[0045] In some embodiments, to ensure the arrangement of longitudinal reinforcement within the steel-concrete composite column 200, such as... Figure 4 and Figure 5 As shown, each flange plate 11 of each flange plate 10 has a reserved bar hole 111 or a reserved bar groove 112 for the longitudinal reinforcing bars of the steel-concrete column 200 to pass through, and the reserved bar holes 111 or reserved bar grooves 112 on each flange plate 11 of each flange plate 10 are aligned vertically.
[0046] In some embodiments, such as Figure 4 and Figure 5As shown, each flange plate assembly 10 has an upper flange plate 113 with a rebar pre-reserved groove 112 and a lower flange plate 114 with a rebar pre-reserved hole 111 corresponding to the rebar pre-reserved groove 112. The rebar pre-reserved groove 112 can extend from the edge of the upper flange plate 113 away from the steel section 201 toward the side closer to the steel section 201, and there can be two or more rebar pre-reserved grooves 112. Each rebar pre-reserved groove 112 can be located on both sides of the web plate 20 and arranged at intervals with the longitudinal rebar of the reinforced concrete beam 300 to avoid interference between the longitudinal rebar in the steel-concrete column 200 and the longitudinal rebar of the reinforced concrete beam 300. Meanwhile, the reserved holes 111 for reinforcing bars can be elongated holes such as slotted holes or elliptical holes. The reserved holes 111 for reinforcing bars can be two or more that are compatible with the reserved slots 112 for reinforcing bars. At the same time, at least part of the reserved holes 111 for reinforcing bars coincides with the reserved slots 112 for reinforcing bars. That is, the projected area of the reserved slots 112 for reinforcing bars on the lower flange plate 114 partially or completely coincides with the projected area of the reserved holes 111 for reinforcing bars on the lower flange plate 114, so that the longitudinal reinforcing bars of the steel-concrete column 200 can pass through the reserved slots 112 for reinforcing bars and the reserved holes 111 for reinforcing bars.
[0047] In some embodiments, such as Figure 1 and Figure 2 As shown, the connecting component body 100 may also include stiffening ribs 30 adapted to the flange plate assembly 10, that is, a stiffening rib 30 is provided at the elevation position of each flange plate assembly 10, and the stiffening ribs 30 can be welded to the steel section 201 and away from the surface of the flange plate assembly 10, so as to ensure the force transmission at the connection node between the steel-concrete column 200 and the reinforced concrete beam 300, and to improve the connection strength between the connecting component body 100 and the steel section 201 in the steel-concrete column 200.
[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the steel 201 in the steel-concrete composite column 200 can be a box-shaped steel, and the stiffening rib 30 can be a rectangular plate. The stiffening rib 30 can be welded into the cavity of the box-shaped steel and located at the elevation of the flange plate assembly 10. Thus, at the same elevation of the flange plate assembly 10, a stiffening rib 30 can be used to improve the connection strength between multiple connecting component bodies 100 connected to the side wall of the steel 201.
[0049] Of course, the steel 201 in the steel-concrete column 200 can also be H-beams or cross-shaped steel, etc. In this case, multiple stiffening ribs 30 can be welded to improve the connection strength between the multiple connecting component bodies 100 connected to the side wall of the steel 201.
[0050] This application also discloses a steel-concrete composite structure, including a steel-concrete composite column 200, a reinforced concrete beam 300, and a connecting component. The steel-concrete composite column 200 and the reinforced concrete beam 300 can be connected by the connecting component, and the connecting component adopts the beam-column connecting component disclosed in the above embodiment. Therefore, it has all the technical effects of the above beam-column connecting component, which will not be repeated here.
[0051] In some embodiments, the steel-concrete composite column 200 may include box-shaped steel and reinforced concrete 202 covering the outside of the box-shaped steel, and as shown in the figure. Figure 1 As shown, the steel-concrete composite column 200 can be connected to multiple reinforced concrete beams 300. At the same time, the top longitudinal reinforcement 301 and bottom longitudinal reinforcement 302 of each reinforced concrete beam 300 can be fixed to the four outer walls of the box-shaped steel section through connecting components to ensure the reliability of the connection between the reinforced concrete beam 300 and the steel-concrete composite column 200. It eliminates the need to cut the reinforcement bars and then connect them to the steel-concrete composite columns 200 at both ends, simplifying the construction process and making the connection quality more reliable.
