Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a pre-embedded beam-column joint for a cantilevered canopy. Background Technology

[0002] For building structures with large spans, high loads, complex stresses, and irregular vertical layouts, using traditional reinforced concrete construction often presents numerous challenges, such as the expansion of structural component dimensions, increased costs, and compression of usable space.

[0003] Specifically, when the cantilever section of a steel canopy is designed to be quite large, the concrete embedded parts not only need to withstand bending and shear forces, but may also face enormous bending moments. This makes it difficult for existing steel reinforcement embedded parts to meet structural requirements. Under extreme stress conditions, the reliability of traditional embedded parts may be affected, making it difficult to meet long-term safety standards and ensuring safety and stability. Utility Model Content

[0013] Furthermore, the second reinforcing cage includes multiple second stirrups, multiple third stirrups, and four groups of second reinforcing bars. The multiple second stirrups are spaced apart along the first direction on the outer periphery of the second steel section. The second stirrups are square. The four groups of second reinforcing bars are arranged between the second stirrups and the second steel section, and are arranged one-to-one according to the four corners of the square shape of the second stirrups. The second group of reinforcing bars includes a fourth longitudinal bar, a fifth longitudinal bar, and a sixth longitudinal bar.

[0015] Furthermore, the fifth longitudinal bar has a bent portion at one end near the first steel section, the bent portion bends away from the first steel section, and the bent portion is sequentially connected to the third longitudinal bars of the two first steel bar groups distributed in the first direction.

[0016] Furthermore, the third reinforcing cage includes multiple fourth stirrups and two third reinforcing bar groups.

[0019] Compared with the prior art, the beneficial effects of this embodiment of the pre-embedded beam-column joint for a cantilevered canopy are as follows: the front end of the second steel section is fixed to the rear end face of the first steel section; a first reinforcing cage is fitted onto the first steel section; a second reinforcing cage is fitted onto the second steel section; and a third reinforcing cage passes through the column along a second direction. Through the combined use of the first steel section and the first reinforcing cage, as well as the combined use of the second steel section and the second reinforcing cage, the structural strength and stiffness of the column and the first beam are significantly improved. The first and second steel sections, as a skeleton, provide good load-bearing capacity and bending resistance, while the first and second reinforcing cages, through their internal reinforcing mesh, enhance the tensile strength and integrity of the concrete. The third steel section… No structural steel is installed inside the reinforcing cage because the cantilever beam extends in the same direction as the first beam. The cantilever beam will generate a large bending moment on the column and the first beam. The second beam only serves to connect adjacent columns, so no structural steel is installed inside the second beam. The end of the second structural steel is connected to the first structural steel. The third reinforcing cage passes through the column, and one end of the cantilever beam is set on the column. The extension direction of the cantilever beam is consistent with the first beam, ensuring the connection consistency of the beam-column joint, guaranteeing its strength and stiffness, avoiding stress concentration and potential failure points, which is conducive to improving the stability and seismic performance of the overall structure, thereby improving the load-bearing capacity of the cantilever beam and ensuring its long-term safety and stability.

[0036] Furthermore, the terms "first," "second," etc., are primarily used to distinguish different devices, elements, or components (which may be the same or different in specific type and construction), and are not intended to indicate or imply the relative importance or quantity of the indicated devices, elements, or components. Unless otherwise stated, "a plurality of" means two or more.

[0037] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0038] like Figure 1 , 2 As shown in Figure 3, an embodiment of this utility model of a cantilevered canopy with embedded beam-column joint includes:

[0039] Column 1, which includes a first steel section 11 and a first reinforcing cage 12. The first steel section 11 extends along the third direction Z, and the first reinforcing cage 12 is fitted around the outer periphery of the first steel section 11.

[0040] The first beam 2 includes a second steel section 21 and a second reinforcing cage 22. The second steel section 21 extends along the first direction X. The front end of the second steel section 21 is fixedly connected to the rear end face of the first steel section 11. The second reinforcing cage 22 is sleeved on the outer periphery of the second steel section 21.

[0041] The second beam 3 includes a third steel cage 31, which extends through the column 1 along the second direction Y.

[0042] The cantilever beam 4 is set on the front end face of the column 1, and the extension direction of the cantilever beam 4 is consistent with that of the first beam 2.

[0043] Among them, the first direction X, the second direction Y, and the third direction Z are all perpendicular to each other.

[0044] Based on the above technical solution, the front end of the second steel section 21 is fixed to the rear end face of the first steel section 11. A first reinforcing cage 12 is fitted onto the first steel section 11, and a second reinforcing cage 22 is fitted onto the second steel section 21. A third reinforcing cage 31 passes through the column 1 along the second direction Y. Through the combined use of the first steel section 11 and the first reinforcing cage 12, as well as the combined use of the second steel section 21 and the second reinforcing cage 22, the structural strength and stiffness of the column 1 and the first beam 2 are significantly improved. The first steel section 11 and the second steel section 21, as a skeleton, provide good load-bearing capacity and bending resistance, while the first reinforcing cage 12 and the second reinforcing cage 22 enhance the bending strength and integrity of the concrete through their internal reinforcing mesh. The third reinforcing cage 31 does not contain any reinforcing cages. Because the cantilever beam 4 extends in the same direction as the first beam 2, it will generate a large bending moment on the column 1 and the first beam 2. The second beam 3 only serves to connect adjacent columns 1, so no steel is installed inside the second beam 3. The end of the second steel 21 is connected to the first steel 11, and the third steel cage 31 passes through the column 1. One end of the cantilever beam 4 is set on the column 1, and the extension direction of the cantilever beam 4 is consistent with that of the first beam 2. This ensures the consistency of the beam-column connection, guarantees its strength and stiffness, avoids stress concentration and potential failure points, and helps to improve the stability and seismic performance of the overall structure. This improves the load-bearing capacity of the cantilever beam 4 and ensures its long-term safety and stability.

[0045] It should be noted that concrete was poured into column 1, first beam 2, and second beam 3.

[0046] Preferably, the pre-embedded beam-column node of the cantilevered canopy also includes an installation plate 5. The first steel 11, the second steel 21, and the cantilever beam 4 are I-beams. The installation plate 5 is set on the front end face of the column 1, and the front end face of the installation plate 5 is flush with the front end face of the column 1. The cantilever beam 4 is set on the front end face of the installation plate 5. The web of the second steel 21 is directly opposite the web of the first steel 11. The flanges of the second steel 21 pass through the two flanges of the first steel 11 in sequence and are connected to the installation plate 5. The two flanges of the second steel 21 are directly opposite the two flanges of the cantilever beam 4. A connecting plate 6 is provided between the rear end face of the installation plate 5 and the front end face of the first steel 11. The two ends of the connecting plate 6 in the third direction Z are respectively connected to the two flanges of the second steel 21. The front and rear ends of the connecting plate 6 are directly opposite the web of the cantilever beam 4 and the web of the first steel 11, respectively. A connecting plate 6 is provided between the first steel section 11 and the mounting plate 5. The upper and lower ends of the connecting plate 6 are connected to the flanges of the second steel section 21 extending onto the mounting plate 5. The connecting plate 6 and the flanges combine to form an I-beam. Part of the web of the first steel section 11 and the flanges of the second steel section 21 form an I-beam, thereby connecting the front end of the second steel section 21 with the rear end of the cantilever beam 4 with an I-beam, ensuring the continuity of the steel structure in the first direction X, thereby increasing its stiffness and connection strength, and ensuring the load-bearing capacity of the cantilever beam 4.

[0047] More preferably, the first reinforcing cage 12 includes a plurality of first stirrups 121 and four first reinforcing bar groups 122. The plurality of first stirrups 121 are spaced apart along the third direction Z around the outer periphery of the first steel section 11. The first stirrups 121 are square. The four first reinforcing bar groups 122 are arranged between the first stirrups 121 and the first steel section 11 and are arranged one-to-one according to the four corners of the square shape of the first stirrups 121. The first reinforcing bar group 122 includes a first longitudinal bar 1221, a second longitudinal bar 1222, a third longitudinal bar 1223 and a plurality of first tie bars 1224. The first longitudinal bar 1221, the second longitudinal bar 1222 and the third longitudinal bar 1223 are all along the third direction Z. Extending, the first longitudinal reinforcement 1221 is set at the four corners of the first stirrup 121; the second longitudinal reinforcement 1222 is set on the first stirrup 121, and the second longitudinal reinforcement 1222 is spaced apart from the first longitudinal reinforcement 1221, with the second longitudinal reinforcement 1222 located on the side closer to the second steel section 21; the third longitudinal reinforcement 1223 is set on the first stirrup 121, and the third longitudinal reinforcement 1223 is spaced apart from the first longitudinal reinforcement 1221, with the third longitudinal reinforcement 1223 located on the side away from the second steel section 21; the two ends of the first tie bar 1224 are respectively set on the second longitudinal reinforcement 1222 and the third longitudinal reinforcement 1223, and multiple first tie bars 1224 are arranged at intervals along the third direction Z. The two ends of the first tie bar 1224 are respectively set on the second longitudinal bar 1222 and the third longitudinal bar 1223 to tighten the first steel cage 12. When pouring concrete, it can produce a certain restraint effect on the concrete and reduce the deformation of the first steel cage 12 after the concrete is poured, thus ensuring the structural stability of the first steel cage 12.

[0048] More preferably, the second reinforcing cage 22 includes multiple second stirrups 221, multiple third stirrups 222, and four second reinforcing bar groups 223. The multiple second stirrups 221 are spaced apart along the first direction X around the outer periphery of the second steel section 21. The second stirrups 221 are square. The four second reinforcing bar groups 223 are arranged between the second stirrups 221 and the second steel section 21 and are arranged one-to-one according to the four corners of the square shape of the second stirrups 221. The second reinforcing bar group 223 includes a fourth longitudinal bar 2231, a fifth longitudinal bar 2232, and a sixth longitudinal bar 2233. The fourth longitudinal bar 2231, the fifth longitudinal bar 2232, and the sixth longitudinal bar 2233 all extend along the first direction X. 2231 is set at the four corners of the second stirrup 221; the fifth longitudinal bar 2232 is set on the second stirrup 221, the fifth longitudinal bar 2232 and the fourth longitudinal bar 2231 are spaced apart, the fifth longitudinal bar 2232 is located on the side close to the first steel section 11; the sixth longitudinal bar 2233 is set on the second stirrup 221, the sixth longitudinal bar 2233 and the fourth longitudinal bar 2231 are spaced apart, the sixth longitudinal bar 2233 is located on the side away from the first steel section 11, a plurality of third stirrups 222 are sleeved on the outer periphery of the four fifth longitudinal bars 2232 and connected to the fifth longitudinal bars 2232, a plurality of second stirrups 221 and a plurality of third stirrups 222 are spaced apart from each other along the first direction X. Multiple second stirrups 221 and multiple third stirrups 222 are spaced apart along the first direction X. When pouring concrete, the concrete easily adheres to the third stirrups 222 near the second steel 21, so that the concrete can better fill the gap between the second steel 21 and the third stirrups 222, and can also greatly increase the structural strength of the first beam 2.

[0049] More preferably, the second steel cage 22 further includes four connecting bars 224 and multiple second tie bars 225. The connecting bars 224 extend along the first direction X and are disposed on the web of the second steel section 21. The connecting bars 224 correspond one-to-one with the sixth longitudinal bars 2233 in the second direction Y. The two ends of the second tie bars 225 are respectively connected to the sixth longitudinal bars 2233 and the connecting bars 224. The multiple second tie bars 225 are spaced apart along the first direction X. The connecting bar 224 is set on the web of the second steel section 21. The two ends of the second tie bar 225 are connected to the sixth longitudinal bar 2233 and the connecting bar 224 respectively. The second tie bar 225 has a binding effect on the second stirrup 221. When pouring concrete, it can produce a certain restraint effect on the concrete and reduce the deformation of the second steel cage 22 after the concrete is poured, ensuring the structural stability of the second steel cage 22. Moreover, the second tie bar 225 increases the connection structure between the second stirrup 221 and the second steel section 21, increases the attachment points of the concrete, and can effectively increase the structural strength of the first beam 2 after the concrete is poured.

[0050] More preferably, the fifth longitudinal reinforcement 2232 has a bent portion 22321 at one end near the first steel section 11. The bent portion 22321 bends away from the first steel section 11 and is sequentially connected to the third longitudinal reinforcement 1223 of the two first steel reinforcement groups 122 distributed in the first direction X. The bent portion 22321 is sequentially connected to the third longitudinal reinforcement 1223 of the two first steel reinforcement groups 122 distributed in the first direction X. The front end of the second steel section 21 is connected to the rear end face of the first steel section 11. The multi-structure connection between the column 1 and the first beam 2 increases the structural connection performance between the column 1 and the first beam 2, ensuring the connection strength and rigidity of the beam-column joint.

[0051] More preferably, the third reinforcing cage 31 includes a plurality of fourth stirrups 311 and two third reinforcing bar groups 312. The plurality of fourth stirrups 311 are spaced along the second direction Y and sleeved around the outer periphery of the two third reinforcing bar groups 312. The third reinforcing bar groups 312 are spaced along the third direction Z. The third reinforcing bar groups 312 include a plurality of seventh longitudinal bars 3121. The seventh longitudinal bars 3121 extend along the second direction Y and are spaced along the first direction X. The front side of the front wing plate of the first steel section 11 is provided with a through plate 7. The lower end of the through plate 7 is connected to the wing plate of the second steel section 21. Some of the seventh longitudinal bars 3121 penetrate the web members of the first steel section 11, and the remaining seventh longitudinal bars 3121 penetrate the through plate 7. Some of the seventh longitudinal reinforcement bars 3121 pass through the web of the first steel section 11, and the remaining seventh longitudinal reinforcement bars 3121 pass through the through plate 7, increasing the consistency of the connection between the column 1 and the second beam 3. The column 1, the first beam 2, the second beam 3, and the cantilever beam 4 are all connected through beam-column joints. The concrete pouring volume of the beam-column joint is large, which can effectively avoid the problem of stress concentration, and the stress transfer effect is good, which can ensure the stability of the overall structure.

[0052] Preferably, the flange of the first steel section 11 has multiple first studs 8 on the side facing away from the web, and the multiple first studs 8 are arranged in a matrix. The flange of the second steel section 21 has multiple second studs 9 on the side facing away from the web, and the multiple second studs 9 are arranged in a matrix. The multiple first studs 8 and second studs 9 can increase the adhesion area between the concrete and the first steel section 11 and the second steel section 21, ensuring the structural strength of the column 1 and the first beam 2. The number of studs should be set to be equal to the tensile and compressive forces borne by the flange, so that the tensile and compressive forces are smoothly transferred to the first beam 2.

[0053] More preferably, the first studs 8 on the first steel section 11 are spaced 110mm-130mm apart in the third direction Z; the second studs 9 on the second steel section 21 are spaced 110mm-130mm apart in the first direction X. Preferably, the spacing is 120mm. If the spacing is less than 110mm, the spacing between the studs is too small, making it difficult to ensure the fluidity of the concrete, which can easily lead to voids in the first beam 2 or column 1, resulting in unstable structural stress. If the spacing is greater than 130mm, the adhesion of the concrete is poor, making it difficult to solidify on the surface of the studs. The high fluidity of the concrete can easily lead to concrete waste.

[0054] In summary, this utility model embodiment provides a pre-embedded beam-column node for a cantilevered canopy. The front end of the second steel section 21 is fixed to the rear end face of the first steel section 11. A first reinforcing cage 12 is fitted onto the first steel section 11, and a second reinforcing cage 22 is fitted onto the second steel section 21. A third reinforcing cage 31 passes through the column 1 along the second direction Y. Through the combined use of the first steel section 11 and the first reinforcing cage 12, as well as the combined use of the second steel section 21 and the second reinforcing cage 22, the structural strength and stiffness of the column 1 and the first beam 2 are significantly improved. The first steel section 11 and the second steel section 21, as a skeleton, provide good load-bearing capacity and bending resistance, while the first reinforcing cage 12 and the second reinforcing cage 22 enhance the tensile strength and integrity of the concrete through their internal reinforcing mesh. No structural steel is installed inside the third reinforcing cage 31 because the cantilever beam 4 extends in the same direction as the first beam 2. The cantilever beam 4 will generate a large bending moment on the column 1 and the first beam 2. The second beam 3 only serves to connect two adjacent columns 1, so no structural steel is installed inside the second beam 3. The end of the second structural steel 21 is connected to the first structural steel 11. The third reinforcing cage 31 is installed through the column 1. One end of the cantilever beam 4 is installed on the column 1. The extension direction of the cantilever beam 4 is consistent with that of the first beam 2, which ensures the connection consistency of the beam-column joint, guarantees its strength and stiffness, avoids stress concentration and potential failure points, and helps to improve the stability and seismic performance of the overall structure, thereby improving the load-bearing capacity of the cantilever beam 4 and ensuring its long-term safety and stability.

[0055] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
