Description

Technical Field

[0001] This application relates to the field of construction, and particularly to a beam-column connection structure. Background Art

[0002] In the field of construction, especially in high-rise buildings and long-span structures, steel reinforced concrete (also known as steel-concrete composite or reinforced concrete) is a common structural form that combines the advantages of concrete and steel, providing higher load-bearing capacity and better seismic performance. In a steel reinforced concrete structure, at the joint of the beam and the column, steel sections (such as I-beams or H-beams) are embedded in the concrete to form a composite load-bearing member that provides rigidity and load-bearing capacity, while the concrete provides external protection and fire resistance. Stirrups are a key component in a steel reinforced concrete structure used to improve the shear strength and ductility of columns or beams. In a steel reinforced concrete structure, the role of stirrups is equally important, but their connection method and arrangement with the steel section need to be specifically considered to ensure the stability and safety of the overall structure. The stirrups surround the steel section and the concrete to form a cage-like structure to ensure an effective connection between the steel section and the concrete. The spacing, diameter, and shape (such as circular, square, or rectangular) of the stirrups need to be optimized according to the structural design and load requirements. At the corners of the steel section, the stirrups are usually connected to the steel section by bending or welding to form a closed ring structure to enhance the stiffness and shear resistance of the joint area.

[0003] In the joint area of a steel reinforced concrete column and beam, the stirrups need to surround the steel sections of the column and the beam, and the steel web of the steel section occupies the space in the center of the joint, restricting the layout space of the stirrups. To ensure the integrity and stability of the column, beam, and joint area, it is necessary for the stirrups to be effectively connected to the steel web of the beam. In the joint area, that is, at the intersection of the column and the beam, there is a situation where the stirrups conflict with the steel web of the steel beam, so the conflict between the two restricts the choice of the connection method between the stirrups and the steel web of the steel beam.

Detailed implementation manners

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0035] In the present invention, terms such as "upper", "inner", "outer", etc. indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit that the indicated device, element or component must have a specific orientation, or be constructed and operated in a specific orientation.

[0036] Moreover, in addition to being used to indicate orientation or positional relationship, some of the above terms may also be used to represent other meanings. For example, the term "upper" may also be used to represent a certain attachment relationship or connection relationship in some cases. For those of ordinary skill in the art, the specific meanings of these terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the terms "installed", "set up", "provided with", "connected", and "linked" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or there can be internal communication between two devices, components, or parts. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] In addition, terms such as "first", "second", etc. are mainly used to distinguish different devices, components, or parts (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, components, or parts. Unless otherwise specified, the meaning of "a plurality" is two or more.

[0039] In the construction field, especially in high-rise buildings and long-span structures, steel reinforced concrete (also known as steel-concrete composite or reinforced concrete) is a common structural form that combines the advantages of concrete and steel, providing higher load-bearing capacity and better seismic performance. In a steel reinforced concrete structure, to enhance the load-bearing capacity and stability of beams and columns, stiffeners (such as I-beams or H-beams) are embedded in the concrete of beams and columns to form a composite load-bearing member that provides rigidity and load-bearing capacity, while the concrete provides external protection and fire resistance. Stirrups are a key component in a steel reinforced concrete structure used to improve the shear strength and ductility of columns or beams. In a steel reinforced concrete structure, the role of stirrups is equally important, but their connection method and arrangement with the steel need to be specially considered to ensure the stability and safety of the overall structure. The stirrups surround the steel and concrete to form a cage-like structure to ensure effective connection between the steel and the concrete. The spacing, diameter, and shape (such as circular, square, or rectangular) of the stirrups need to be optimized according to the structural design and load requirements. At the corners of the steel, the stirrups are usually connected to the steel by bending or welding to form a closed ring structure to enhance the stiffness and shear resistance of the joint area.

[0040] In the joint area of a steel reinforced concrete column and beam, stirrups need to surround the steel shapes of the column and beam. The steel web of the steel shape occupies the space at the center of the joint, restricting the layout space of the stirrups. To ensure the integrity and stability of the column, beam, and joint area, it is necessary for the stirrups to be effectively connected to the steel web of the beam. In the joint area, that is, at the intersection of the column and beam, there are situations where the stirrups conflict with the steel web of the steel beam.

[0041] To solve the above problems, as Figure 1 shown, Figure 1 is a schematic diagram of the connection structure between the stirrup and the stiffener in the related art. A stiffener a is provided on the steel shape 200 at the beam-column connection node, and the stiffener a is welded to the conflicting stirrup b. However, since the shear force of the steel reinforced concrete column is generally relatively large, the required diameter of the stirrups is large and there are many layers. Therefore, there are many stiffeners a at the joint of the steel reinforced concrete column and beam, the steel bars are dense, and the on-site welding volume of the steel bars is large, making it difficult to ensure the construction quality. The small spacing of the stiffeners a is caused by the large number of stirrup layers at the local area, and the construction is difficult.

[0042] Based on this, the present application discloses a beam-column connection structure. The stirrups are directly tied to the tying part of the support member to achieve the connection between the beam and the column, and it is allowed to adjust the connection position of the stirrups and the support member according to the actual situation on site. Such a connection method allows assembly deviation, reduces the on-site welding workload, reduces the on-site construction difficulty, and improves the construction efficiency. The technical solution of the present application will be further described below in conjunction with the embodiments and the drawings.

[0043] Please refer to Figure 2 and Figure 3 , Figure 2 which is a schematic diagram of the beam 2-column 1 connection structure 100 disclosed in the embodiment of the present application. Figure 3 For Figure 2Cross-sectional view at A-A in [description] (including stiffening member 21, support member 22 and stirrup 3). An embodiment of the present application discloses a beam-column connection structure 100, which includes a column 1, a beam 2, a support member 22 and a stirrup 3. The column 1 extends along the first direction X, and column stirrups 11 are provided in the column 1 along the first direction X, and the column stirrups 11 are arranged close to the edge of the column 1; the beam 2 extends along the second direction Y, the first end of the beam 2 extends into the column 1, and a stiffening member 21 is provided in the beam 2. The stiffening member 21 is arranged in the beam 2 along the second direction Y, and the stiffening member 21 includes a web 212 and flanges 211 connected to both sides of the web 212; the support member 22 is arranged at the first end of the beam 2, and both ends of the support member 22 in the first direction X are respectively fixedly connected to the two flanges 211, and a tying portion 221 is provided on the support member 22; one end of the stirrup 3 is connected to the column stirrup 11, and the other end is connected to the tying portion 221 to connect the column 1 and the beam 2. The first end of the beam 2 is the beam-column joint of the beam 2 and the column 1. The stirrup 3 is directly tied to the tying portion 221 of the support member 22 to realize the connection between the beam 2 and the column 1, and allows the connection position of the stirrup 3 and the support member 22 to be adjusted according to the actual situation on site. Such a connection method allows assembly deviation, reduces the on-site welding workload, reduces the on-site construction difficulty, and improves the construction efficiency.

[0044] It should be noted that the shape of the stirrup 3 can be circular, square or rectangular, and needs to be optimized according to the structural design and load requirements. This embodiment does not limit this.

[0045] It can be understood that the support member 22 can be provided with a through hole 221a, refer to Figure 4 , Figure 4 which is a schematic diagram of a connection structure between the stirrup 3 and the support member 22. One end of the stirrup 3 passes through the through hole 221a and is tied to the support member 22.

[0046] Combined with Figure 3 and Figure 5 , Figure 5 is Figure 3 Cross-sectional view at B-B in [description] (including stirrup 3 and support member 22). As an alternative embodiment, a gap is formed between the support member 22 and the web 212, and the tying portion 221 is the first edge 221b of the support member 22. The first edge 221b is the edge of the support member 22 facing the web 212, and the stirrup 3 passes through the gap and is tied to the first edge 221b. In this way, on site, the stirrup 3 is directly tied to the first edge 221b of the support member 22, which is convenient for operation and construction, and improves the construction efficiency.

[0047] Optionally, the support member 22 is in a plate-like structure and is arranged perpendicular to the web 212. In this way, the support member 22 supports the two flanges 211. Since the support member 22 in the plate-like structure is arranged perpendicular to the web 212, the thickness direction of the support member 22 is arranged along the second direction Y, which facilitates tying the stirrup 3 to the first edge 221b of the support member 22.

[0048] Combined with Figure 2 and Figure 3 , it should be noted that there are two support members 22, and the two support members 22 are symmetrically arranged with respect to the web 212. Since both sides of the web 212 need to be connected to the conflicting stirrups 3, support members 22 are provided on both sides of the web 212 in the direction perpendicular to the web 212. In this way, on the one hand, the supporting force of the support member 22 on the flange 211 is stronger, and on the other hand, the symmetrically arranged support members 22 can disperse the load more evenly, increase the symmetry and stability of the structure, avoid local overloading, and improve the safety of the structure.

[0049] As an alternative embodiment, combined with Figure 3 , each support member 22 is arranged at the edge close to the flange 211 in the direction perpendicular to the web 212. In this way, not only can the shear force at the connection between the beam 2 and the column 1 be resisted more effectively, enhancing the shear resistance performance, but also the distance between the stirrups 3 of the column 1 and the support plate is closer, the connection of the stirrups 3 is more convenient, easy to operate, and the construction efficiency is improved.

[0050] Referring to Figure 2 , in some embodiments, column stirrups 11 are provided at the four corners close to the inner side of the column 1. The column stirrups 11 around the inner side of the column 1 are successively the first column stirrup 111, the second column stirrup 112, the third column stirrup 113, and the fourth column stirrup 114. The column stirrups 11 on both sides close to the first end of the beam 2 are the second column stirrup 112 and the third column stirrup 113. The stirrup 3 includes a first stirrup 31 and a second stirrup 32. One end of the first stirrup 31 is tied to the first column stirrup 111, bypasses the second column stirrup 112, and the other end of the first stirrup 31 is tied to the support member 22 close to the second column stirrup 112. One end of the second stirrup 32 is tied to the first column stirrup 111, bypasses the fourth column stirrup 114 and the third column stirrup 113, and the other end of the second stirrup 32 is tied to the support member 22 close to the third column stirrup 113. Such a stirrup 3 tying design around the inner side of the column 1 ensures a more firm connection between the column stirrups 11 and the beam 2.

[0051] Combined with Figure 3, in some possible embodiments, the distance between the support member 22 and the web 212 is greater than or equal to 1000 mm. A fixing plate 23 is provided between the support member 22 and the web 212. One end of the fixing plate 23 is fixedly connected to the support member 22, and the other end is fixedly connected to the web 212. The setting of the fixing plate 23 is applicable to the case where the distance between the support member 22 and the web 212 is relatively large, preventing the distance from being too long and causing deformation of the support member 22 or the web 212, enhancing the connection strength between the support member 22 and the web 212, and ensuring the stability of the structure.

[0052] It can be understood that when the distance between the support member 22 and the web 212 is less than 1000 mm, there is no need to provide the fixing plate 23 between the support plate and the web 212. The distance between the support member 22 and the web 212 is relatively small, and the overall structure has good stability without being fixed by the fixing plate 23. On the premise of ensuring stability, the material cost is saved.

[0053] Optionally, the fixing plate 23 can be arranged at any position between the two flanges 211 along the first direction X. Combining Figure 3 , one end of the fixing plate 23 is connected to the middle part of the support member 22 along the first direction X, and the other end is connected to the middle part of the web 212 along the first direction X. In this way, the symmetry of the overall structure is ensured, the bending and shear resistance performance of the structure is improved, the stress distribution is optimized, and the structure is made more stable.

[0054] It can be understood that the width of the support member 22 in the direction perpendicular to the web 212 and the width of the fixing plate 23 in the first direction X are both obtained by rounding after equivalent strength conversion. According to the requirements for the strength of flexural members in the "Standard for Design of Steel Structures", for a solid-web member bent in the main plane, its flexural strength should be calculated by the following formula:

[0055]

[0056] In the formula:

[0057] M x 、M y —— The design values of the bending moments about the x-axis and y-axis at the same cross-section (N·mm);

[0058] W nx 、W ny —— The net section moduli about the x-axis and y-axis;

[0059] γ x 、γ y —— The section plastic development coefficients about the main axes x and y;

[0060] f —— The design value of the flexural strength of the steel (N / mm 2 ).

[0061] When a concentrated load acting along the web plane is applied to the upper flange of the beam and no supporting stiffener is provided at the location of the load, the local bearing strength at the upper edge of the web calculation height shall be calculated according to the following formula:

[0062]

[0063] l z = a + 5h y + 2h R

[0064] Where:

[0065] F——Design value of the concentrated load. For dynamic loads, the dynamic coefficient shall be considered (N);

[0066] ψ——Increase coefficient of the concentrated load; for heavy-duty crane girders, ψ = 1.35; for other girders, ψ = 1.0;

[0067] l z ——Assumed distribution length of the concentrated load at the upper edge of the web calculation height;

[0068] I R ——Moment of inertia of the rail about its own centroidal axis (mm 4 );

[0069] I f ——Moment of inertia of the upper flange of the beam about the mid-plane of the flange (mm 4 );

[0070] a——Supporting length of the concentrated load along the span direction of the beam (mm). For the wheel load on the rail, 50 mm can be taken;

[0071] h y ——Distance from the top surface of the beam to the upper edge of the web calculation height; for welded beams, it is the thickness of the upper flange, and for rolled I-section beams, it is the distance from the top surface of the beam to the point where the transition to the web is completed (mm);

[0072] h R ——Height of the rail. For beams without rails on the top of the beam, the value is taken as 0 (mm);

[0073] f——Design value of the flexural strength of the steel (N / mm 2 ).

[0074] In this way, the width of the support member 22 in the direction perpendicular to the web 212 and the width of the fixing plate 23 in the first direction X obtained by rounding after the above equal-strength conversion ensure that the strength of the support member 22 matches the required bearing capacity, avoid the strength reduction caused by insufficient width, contribute to standardized production, simplify the material selection and construction process, and improve the engineering efficiency.

[0075] As an alternative embodiment, in combination with Figure 5 , the thickness direction of the fixing plate 23 is arranged along the second direction Y, and the thickness of the support member 22 and the fixing plate 23 in the second direction Y is greater than or equal to 10 mm. This enhances the bearing capacity and bending resistance of the support member 22, ensuring the stability and safety of the connection structure when bearing gravity and lateral loads. At the same time, sufficient thickness is also beneficial for welding with the reinforcing member 21, improving the reliability of the connection.

[0076] In some embodiments, the thickness of the support member 22 in the second direction Y is the same as the diameter of the stirrup 3. When the thickness of the support member 22 in the second direction Y is greater than the diameter of the stirrup 3, the tying operation of the stirrup 3 is relatively difficult and the tying operation efficiency is low; when the thickness of the support member 22 in the second direction Y is less than the diameter of the stirrup 3, the stirrup 3 is tied to the support member 22, which may cause damage to the support member 22. Therefore, when the thickness of the support member 22 in the second direction Y is the same as the diameter of the stirrup 3, on the premise of ensuring the connection strength with the reinforcing member 21, the tying effect is better.

[0077] Optionally, the diameter of the stirrup 3 is greater than or equal to 10 mm. In this way, the strength and rigidity of the stirrup 3 are ensured, which can effectively resist external loads such as wind force, prevent the structure from undergoing excessive deformation or damage, and enhance the overall safety and durability of the structure.

[0078] After the corresponding beam-column steel structure joint is processed and formed, the support member 22 and the fixing plate 23 are welded to the corresponding positions of the reinforcing member 21 in the factory, and then on-site, the stirrup 3 is tied to the first edge 221b of the support member 22, and the beam-column connection structure 100 is then processed, manufactured and installed.

[0079] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the technical solutions of the embodiments of the present invention.
