Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building structure, and particularly relates to an SRC stiff connecting node structure. BACKGROUND

[0002] With the development of urban construction and the progress of building technology, large-span super high-rise buildings have become one of the main directions of building structure development. Steel reinforced concrete structure (referred to as "SRC") made of steel skeleton wrapped by concrete fully utilizes the characteristics of steel and concrete, and has the advantages of large rigidity, good ductility and steel saving compared with reinforced concrete structure. Therefore, the application and promotion of steel reinforced concrete structure in large-span super high-rise buildings are also becoming more and more widespread.

[0003] The main structure of traditional large-span super high-rise buildings is a steel structure, and the structure form is a steel structure support cylinder frame connected structure with a cantilever body. Specifically, the underground is a steel reinforced concrete structure column, and a reinforced concrete beam is arranged on the steel reinforced concrete structure column. In the actual construction process of the steel reinforced concrete structure column and the reinforced concrete beam, the following two ways are usually used for construction: ①. First, a steel bar hole is formed on the steel column, and then the main load-bearing steel bars and the intermediate waist steel bars in the upper and lower parts of the reinforced concrete beam are directly inserted through the steel bar hole of the steel column. ②. First, a connecting sleeve is welded on the steel column corresponding to the beam-column joint position, and then the main load-bearing steel bars in the upper and lower parts of the beam and the intermediate waist steel bars are threadedly connected to the corresponding connecting sleeve.

[0004] However, the first construction method is prone to positioning errors of the steel bar hole and the on-site steel bars due to error accumulation, and a connecting measure needs to be added between the connecting steel bars inserted through the steel bar hole and the beam end steel bars to ensure the connection strength, which is difficult and complicated to construct on site. The second construction method is prone to positioning errors of the connecting sleeve and the on-site steel bars due to error accumulation, and the steel bars and the sleeve are connected through threads, which is relatively complicated to construct on site. SUMMARY

[0008] Two metal sealing plates arranged on both sides of the stiff column part along the first direction, the metal sealing plates being welded and fixed with the steel column;

At the same time, by arranging the connecting plate on at least one side of the stiffening column part along the second direction, in the construction process, the steel skeleton column and the steel skeleton beam are respectively welded and fixed by using the integrally formed first steel plate part and the second steel plate part, which reduces the steel plate splicing in the joint area, which is beneficial to improve the overall force bearing performance of the joint area, and can save the splicing process, construction period and construction cost.

[0037] The embodiments of the present application will be described below in conjunction with Figure 1 and Figure 2 .

[0038] According to the embodiments of the present application, a SRC stiff connection node structure is provided, which comprises a stiff column part, a stiff beam part and a connecting plate 400. The stiff column part comprises a steel column 110 and a first concrete part 120 wrapped around the steel column 110, and the stiff column part is arranged parallel to the vertical direction. A metal sealing plate 200 is arranged on both sides of the stiff column part along the first direction, and the metal sealing plate 200 is welded and fixed with the steel column 110. The stiff beam part is arranged on both sides of the stiff column part along the first direction, and the stiff beam part comprises a steel beam 310 and a second concrete part 320 wrapped around the steel beam 310. The steel beam 310 is welded and fixed with the metal sealing plate 200. The connecting plate 400 is arranged on at least one side of the stiff column part along the second direction, preferably on both sides. The connecting plate 400 comprises a first steel plate part 410 and a second steel plate part 420 which are integrally formed. The first steel plate part 410 is welded and fixed with the steel column 110, and the second steel plate part 420 is welded and fixed with the steel beam 310.

[0039] The connecting node structure of the embodiment is provided with the metal sealing plate 200 on both sides of the stiff beam part along the first direction, and the steel skeleton beam 310 in the stiff beam part replaces the traditional steel bar structure. In the construction process, the steel skeleton beam 310 is welded and fixed to the metal sealing plate 200 by means of the metal sealing plate 200 as a transition connection, which is equivalent to the steel skeleton beam 310 being connected to the steel skeleton column 110 from the stress point of view, and does not affect the stress of the whole node. The steel skeleton beam 310 is directly welded and fixed to the metal sealing plate 200, and does not need to extend into the steel skeleton column 110, so that the collision between the steel skeleton beam 310 and the longitudinal steel bars of the steel skeleton column 110 can be avoided, and the necessary connecting process of part of the longitudinal steel bars of the steel skeleton beam 310 and the steel skeleton column 110 can be saved, thereby increasing the construction convenience and shortening the construction period. At the same time, the connecting plate 400 is arranged on both sides of the stiff column part along the second direction. In the construction process, the first steel plate part 410 and the second steel plate part 420 are integrally formed and are respectively welded and fixed to the steel skeleton column 110 and the steel skeleton beam 310, so that the steel plate splicing of the node area is reduced, which is beneficial to improving the overall stress performance of the node area, and the splicing process can be saved, thereby saving the construction period and construction cost.

[0040] It should be noted that the metal sealing plate 200 is arranged in the connecting node area of the steel skeleton beam 310 and the steel skeleton column 110, as shown in Figure 2 The projection of the metal sealing plate 200 along the first direction overlaps with the stiff column part, that is, the metal sealing plate 200 has the same outer contour line as the stiff column part. On the one hand, the metal sealing plate 200 can replace the column hoop bar at the node position to provide shear bearing capacity for the node, and reduce the construction difficulty of the complex node area steel bar binding. On the other hand, the metal sealing plate 200 can also play the role of the formwork at the node position, which can save materials and reduce the cost of safety protection measures.

[0041] It should be noted that in the embodiment, the first steel plate part 410 and the second steel plate part 420 are integrally formed and are respectively welded and fixed to the steel skeleton column 110 and the steel skeleton beam 310, that is, the non-connecting surfaces of the steel skeleton column 110 and the steel skeleton beam 310 are associated, so that the stress conduction path of the beam-column node is more consistent, and the material waste is reduced and the economy is improved.

[0042] It should be noted that the steel skeleton beam 310 itself has a certain bearing capacity, and the steel skeleton beam 310 can bear the load obtained in the second concrete part 320 stage during construction, and the formwork can be hung on the steel skeleton beam 310 to save the support, thereby facilitating the construction speed and shortening the construction period.

[0043] It can be understood that the first direction and the second direction mentioned in the text are located in the same horizontal plane, and the first direction, the second direction and the vertical direction are perpendicular to each other. In order to facilitate the description, Figure 1 and Figure 2The first direction, the second direction, and the vertical direction are described as the first direction, the second direction, and the vertical direction.

[0044] like Figure 1 As shown, in some embodiments, the stiffening beam further includes connecting reinforcing bars 330, which are disposed within the second concrete section 320 along a first direction. The connecting reinforcing bars 330 are respectively disposed above and below the steel beam 310. Connecting sleeves are provided on opposite sides of the two metal sealing plates 200, and the ends of the connecting reinforcing bars 330 are connected to the connecting sleeves. By combining the connecting reinforcing bars 330 with the second concrete section 320 to form a reinforced concrete structure, when the upper flange of the steel beam 310 is in the compression zone, the connecting reinforcing bars 330 disposed within the second concrete section 320 enable the steel beam 310 and concrete to work together effectively. The cross-sectional strain distribution basically conforms to the plane section assumption, reducing deformation differences between different material combinations, ensuring deformation consistency, and significantly improving the load-bearing capacity.

[0045] In this embodiment, the steel beam 310 and the outer reinforced concrete structure form an integral whole and share the load. The outer concrete can prevent local buckling of the steel beam 310, improve the overall stiffness of the steel beam 310, and significantly improve the torsional buckling performance of the steel beam 310. This allows the strength of the steel to be fully utilized, resulting in greater stiffness and damping than a pure steel structure, which is beneficial for controlling structural deformation. At the same time, the outer concrete increases the durability and fire resistance of the structure. Compared with a reinforced concrete structure, the shear bearing capacity of the stiffened beam is greatly improved, which greatly improves the seismic performance of the structure.

[0046] In some embodiments, the web of the steel beam 310 is provided with a plurality of studs 311 spaced apart along a first direction, and the studs 311 are arranged along a second direction. The design of the studs 311 strengthens the tight connection between the concrete and the steel beam 310, allowing the concrete and the steel beam 310 to work together better, ensuring overall coordinated stress distribution, and thus ensuring consistent deformation.

[0047] Specifically, the upper flange of the steel beam 310 is provided with an vent hole, which extends vertically through the upper flange of the steel beam 310. Because the steel structure, reinforcing bars, and structural measures of the beam-column joint are interwoven, resulting in an extremely complex internal space, this embodiment provides an vent hole on the upper flange of the steel beam 310 to ensure the compactness of the concrete pouring, allowing the concrete and the steel beam 310 to work together better and ensure overall coordinated stress distribution.

[0048] Specifically, the lower flange of the steel beam 310 is provided with an vent hole, which extends vertically through the lower flange of the steel beam 310. Because the steel structure, reinforcing bars, and structural measures of the beam-column joint are interwoven, resulting in an extremely complex internal space, this embodiment provides an vent hole on the lower flange of the steel beam 310 to ensure the compactness of the concrete pouring, allowing the concrete and the steel beam 310 to work together better and ensure overall coordinated stress distribution.

[0049] like Figure 1 As shown, in some embodiments, a first diagonal brace 510 is provided at the lower end of the steel beam 310 along the vertical direction. The first diagonal brace 510 is located on a first side of the stiffening column along a first direction, and the end of the first diagonal brace 510 facing the stiffening column along the first direction is welded and fixed to the metal sealing plate 200. With this arrangement, the first diagonal brace 510 strengthens the load-bearing capacity of the beam-column joint, eliminating the need to weld reinforcing bars at the location where the first diagonal brace 510 is provided on the steel beam 310. This reduces construction difficulty and construction steps while ensuring load-bearing capacity, saving time and costs.

[0050] Specifically, the connecting plate 400 further includes a third steel plate portion 430 integrally formed with the first steel plate portion 410, and the third steel plate portion 430 is welded and fixed to the first diagonal brace 510. With this arrangement, during construction, the steel column 110, steel beam 310 and the first diagonal brace 510 are respectively welded and fixed using the integrally formed first steel plate portion 410, second steel plate portion 420 and third steel plate portion 430, reducing the steel plate splicing in the node area. This not only helps to improve the overall load-bearing performance of the node area, but also saves the splicing process, thus saving construction time and construction costs.

[0051] like Figure 1 As shown, specifically, the side of the third steel plate portion 430 facing the second steel plate portion 420 is connected to the second steel plate portion 420 via a first armpit plate 431. The included angle between the first armpit plate 431 and the second steel plate portion 420 is greater than the included angle between the first diagonal brace 510 and the steel beam 310. Through the transitional connection of the first armpit plate 431, the angle at the connection point of the first armpit plate 431 and the second steel plate portion 420 is increased compared to the angle at the intersection of the extension line of the third steel plate portion 430 and the second steel plate portion 420, which helps prevent stress concentration and damage.

[0052] Specifically, the third steel plate part 430 is connected to the first steel plate part 410 through a second web plate 432 on one side of the first steel plate part 410, and the included angle between the second web plate 432 and the first steel plate part 410 is greater than the included angle between the first inclined brace 510 and the metal closure plate 200. Through the transition connection of the second web plate 432, the angle at the connection between the second web plate 432 and the first steel plate part 410 is expanded compared to the angle at the intersection between the extension line of the third steel plate part 430 and the first steel plate part 410, which is beneficial to prevent stress concentration from causing damage.

[0053] Specifically, the steel reinforced beam 310 is provided with a second inclined brace 520 at the upper end in the vertical direction, the second inclined brace 520 is arranged on the second side of the steel reinforced column part in the first direction, and the second inclined brace 520 is welded and fixed to the metal closure plate 200 at one end of the steel reinforced column part in the first direction. By so arranging, the reinforcing effect of the second inclined brace 520 on the beam-column joint stress is utilized, the steel bars welded at the position where the steel reinforced beam 310 is provided with the second inclined brace 520 are cancelled, the construction difficulty is reduced on the basis of ensuring the stress, and the construction process is reduced, the construction period and cost are saved.

[0054] It can be understood that the first side and the second side mentioned in the text refer to the opposite two sides of the steel reinforced column part in the first direction. For the convenience of description, the embodiment takes the opposite left side of the steel reinforced column part in the first direction as the first side, and the opposite right side of the steel reinforced column part in the first direction as the second side for description and illustration, but should not be understood as explicitly limiting the first side and the second side. Figure 1 Figure 1 It can be understood that the first side and the second side mentioned in the text refer to the opposite two sides of the steel reinforced column part in the first direction. For the convenience of description, the embodiment takes the opposite left side of the steel reinforced column part in the first direction as the first side, and the opposite right side of the steel reinforced column part in the first direction as the second side for description and illustration, but should not be understood as explicitly limiting the first side and the second side.

[0055] Specifically, the connecting plate 400 further comprises a fourth steel plate part 440 integrally formed with the first steel plate part 410, and the fourth steel plate part 440 is welded and fixed with the second inclined brace 520. By so arranging, in the construction process, the integrally formed first steel plate part 410, second steel plate part 420, third steel plate part 430 and fourth steel plate part 440 are respectively welded and fixed with the steel reinforced column 110, steel reinforced beam 310, first inclined brace 510 and second inclined brace 520, which reduces the steel plate splicing of the joint area, is beneficial to improve the overall stress performance of the joint area, and saves the splicing process, construction period and construction cost.

[0056] ​Specifically, the fourth steel plate part 440 is connected to the second steel plate part 420 through a third haunch plate 441 on the side of the second steel plate part 420, and the included angle between the third haunch plate 441 and the second steel plate part 420 is greater than the included angle between the second inclined brace 520 and the steel girder 310. Through the transition connection of the third haunch plate 441, the angle of the connection between the third haunch plate 441 and the second steel plate part 420 is expanded compared to the angle of the intersection between the extension line of the fourth steel plate part 440 and the second steel plate part 420, which is beneficial to prevent damage caused by stress concentration.

[0057] Specifically, the fourth steel plate part 440 is connected to the first steel plate part 410 through a fourth haunch plate 442 on the side of the first steel plate part 410, and the included angle between the fourth haunch plate 442 and the first steel plate part 410 is greater than the included angle between the second inclined brace 520 and the metal sealing plate 200. Through the transition connection of the fourth haunch plate 442, the angle of the connection between the fourth haunch plate 442 and the first steel plate part 410 is expanded compared to the angle of the intersection between the extension line of the fourth steel plate part 440 and the first steel plate part 410, which is beneficial to prevent damage caused by stress concentration.

[0058] It should be noted that the arrangement direction of the third steel plate part 430 is parallel to the length direction of the first inclined brace 510, the arrangement direction of the second steel plate part 420 is parallel to the length direction of the steel girder 310 (i.e. the first direction), and the arrangement direction of the first steel plate part 410 is parallel to the length direction of the steel column 110 (i.e. the vertical direction).

[0059] It can be understood that the first steel plate part 410, the second steel plate part 420, the third steel plate part 430, the fourth steel plate part 440, the first haunch plate 431, the second haunch plate 432, the third haunch plate 441 and the fourth haunch plate 442 are integrally formed to form a connecting plate 400, and the first steel plate part 410, the second steel plate part 420, the third steel plate part 430, the fourth steel plate part 440, the first haunch plate 431, the second haunch plate 432, the third haunch plate 441 and the fourth haunch plate 442 are uniformly deepened in the node area, and according to the requirement of the length of the section in specific application, the eight are obtained by cutting from a whole steel plate.

[0060] It should be noted that the first steel plate part 410 extends downward at least 500 millimeters in the vertical direction from the connection between the second haunch plate 432 and the first steel plate part 410, and the first steel plate part 410 extends upward at least 500 millimeters in the vertical direction from the connection between the fourth haunch plate 442 and the first steel plate part 410; the second steel plate part 420 extends away from the steel column 110 at least 300 millimeters in the first direction from the connection between the first haunch plate 431 and the second steel plate part 420, and the second steel plate part 420 extends away from the steel column 110 at least 300 millimeters in the first direction from the connection between the third haunch plate 441 and the second steel plate part 420; the third steel plate part 430 extends downward at least 500 millimeters in the length direction of the first inclined brace 510 from the connection between the first haunch plate 431 and the third steel plate part 430; the fourth steel plate part 440 extends upward at least 500 millimeters in the length direction of the second inclined brace 520 from the connection between the third haunch plate 441 and the fourth steel plate part 440; the steel plate splicing of the joint area is reduced, and the overall stress performance of the joint area is improved.

[0061] It can be understood that the projection of the connection between the third steel plate part 430 and the first haunch plate 431 in the width direction of the third steel plate part 430 overlaps with the connection between the third steel plate part 430 and the second haunch plate 432; the projection of the connection between the fourth steel plate part 440 and the third haunch plate 441 in the width direction of the fourth steel plate part 440 overlaps with the connection between the fourth steel plate part 440 and the fourth haunch plate 442.
