Description

Technical Field

[0001] The utility model relates to the technical field of steel structure construction, in particular to a connection node between a concrete beam with a steel beam and a steel-framed concrete column. Background Art

[0002] In the field of steel structure construction, the conventional method for connecting concrete beams to steel columns is to install a steel beam inside the concrete beam. The longitudinal reinforcement on the outside of the concrete beam passes around the steel column and then connects to the longitudinal reinforcement inside the concrete beam on the opposite side. The longitudinal reinforcement on the inside is then welded to the upper and lower flanges of the steel beam. Finally, the steel beam is welded to the steel column to achieve the connection between the concrete beam and the steel column. On the one hand, when multiple groups of longitudinal reinforcement are provided vertically at the top and bottom of the concrete beam, the longitudinal reinforcement at the top or bottom of the beam needs to be welded to the upper and lower flanges of the steel beam by overhead welding, which makes the operation difficult and the weld quality cannot be guaranteed. On the other hand, when the cross-section of the steel column is wide, it is difficult for the longitudinal reinforcement on the outside to pass around the steel column, or it is difficult to pass through the steel pipe column when the steel bars are dense.

It should be understood that the terms "first", "second", etc. are used in the present invention to describe various information, but such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of the present invention, "first" information may also be referred to as "second" information, and similarly, "second" information may also be referred to as "first" information.

[0030] like Figure 1-Figure 5As shown, the embodiment of the present application proposes a connection node between a concrete beam with a steel beam and a steel-concrete column, which has a first direction X and a second direction Y perpendicular to each other, including a steel column 1; a concrete beam 2 connected to the opposite ends of the steel column 1 along the first direction X, the top and bottom of the concrete beam 2 are respectively provided with at least two groups of longitudinal reinforcement units 21 extending along the first direction X along the vertical interval, each group of longitudinal reinforcement units 21 includes a plurality of horizontal beam longitudinal reinforcements 211 arranged at intervals along the second direction Y; and a bearing frame 3 extending along the first direction X and arranged in the concrete beam 2 at one end close to the steel column 1, the end of the bearing frame 3 close to the steel column 1 at least partially extending out of the concrete beam 2 and connected to the steel column 1 by welding; the bearing frame 3 includes a steel beam web 31 arranged vertically and extending along the first direction X, the steel beam web 31 extending outward from the concrete beam 2 and connected to the steel column 1 by welding; as shown Figure 3 、 Figure 4 As shown, a first connecting plate 32 is provided on the upper end surface of the steel beam web 31 and is cross-connected with the steel beam web 31, and a second connecting plate 33 is provided on the lower end surface of the steel beam web 31 and is cross-connected with the steel beam web 31; the first connecting plate 32 is an upper flange plate of the steel beam, and the second connecting plate 33 is a lower flange plate of the steel beam. The steel beam web 31, the first connecting plate 32, and the second connecting plate 33 form a steel beam; the first connecting plate 32 is located between the two groups of longitudinal reinforcement units 21 at the top of the beam, and the second connecting plate 33 is located between the two groups of longitudinal reinforcement units 21 at the bottom of the beam; the first connecting plate 32 and the second connecting plate 33 are close to the steel The lower end surface of one end of the column is provided with a plurality of anchors 8 (the anchors 8 are mechanical anchor heads) spaced along the second direction and connected to the longitudinal beam reinforcements 211 located below the first connecting plate 32 and the second connecting plate 33, so as to connect the longitudinal beam reinforcements 211 located below the first connecting plate 32 and the second connecting plate 33 and the support frame 3; the longitudinal reinforcement units 21 located above the first connecting plate 32 and the second connecting plate 33 are connected to the upper end surfaces of the first connecting plate 32 and the second connecting plate 33, and the longitudinal beam reinforcements 211 are connected to the upper end surfaces of the first connecting plate 32 and the second connecting plate 33 by welding (double-sided fillet welding). Figure 2As shown, if the beam longitudinal reinforcement 211 located above the first connecting plate 32 or the beam longitudinal reinforcement 211 located above the second connecting plate 33 is vertically far away from the first connecting plate 32 or the second connecting plate 33, the corresponding beam longitudinal reinforcement 211 needs to be bent downward so that the beam longitudinal reinforcement 211 can overlap the upper end surface of the first connecting plate 32 or the second connecting plate 33 to meet the requirements of welding the beam longitudinal reinforcement 211 to the upper end surface of the first connecting plate 32 or the second connecting plate 33. In this embodiment, all the beam longitudinal reinforcements 211 in the concrete beam 2 are connected and fixed to the first connecting plate 32, the second connecting plate 33 and the anchor 8, and it is no longer necessary to make the beam longitudinal reinforcement 211 on the outside bypass the steel column 1 for connection. This effectively avoids the problem in traditional construction that the beam longitudinal reinforcement on the outside is difficult to bypass the steel column 1 or the steel bars are too dense to pass through the steel column 1; it also avoids the use of overhead welding for the beam longitudinal reinforcement 211 in the concrete beam 2, thereby ensuring the quality of the weld.

[0031] In some embodiments of the present application, Figure 2 As shown, it also includes a column reinforcement unit surrounding the steel column 1 and spaced apart from the steel column 1. The column reinforcement unit includes a plurality of column reinforcements 4 spaced apart and extending vertically. A plurality of first annular stirrups 5 connected to the column reinforcement unit are spaced apart vertically on the outside of the column reinforcement unit. The first annular stirrups 5 and the column reinforcement 4 are connected by wire tying. By surrounding the outer periphery of the steel column 1 with column reinforcement 4 and providing a plurality of first annular stirrups 5 spaced apart vertically on the outside of the column reinforcement 4, the portion of the column reinforcement 4 corresponding to the second connecting plate 33 is fixedly connected to the lower end surface of the second connecting plate 33, thereby further improving the structural strength of the connection node. Figure 2 As shown, a second annular stirrup 9 is provided in the concrete beam 2 and surrounds the beam longitudinal reinforcement 211 . The second annular stirrup 9 is connected to the beam longitudinal reinforcement 211 by wire binding to improve the structural strength of the concrete beam 2 .

[0032] In some embodiments of the present application, Figure 2 As shown, a connector 331 corresponding to the column reinforcement 4 is provided at the lower end surface of the second connecting plate 33 and at a position corresponding to the column reinforcement unit. The connector 331 is a sleeve and is fixed to the lower end surface of the second connecting plate 33 by welding, so that the upper end of the column reinforcement 4 provided at a position corresponding to the steel beam can be inserted into the connector 331 and the connection and fixation between the second connecting plate 33 can be realized, so as to increase the strength of the column reinforcement 4 to the top of the column.

[0033] In some embodiments of the present application, Figure 2 As shown, it also includes first reinforcing plates 34 located at opposite ends of the steel beam web 31 along the second direction Y and perpendicularly connected to the steel beam web 31 (the first reinforcing plates 34 are all welded to the steel beam web 31, the first connecting plate 32, and the second connecting plate 33). Figure 2As shown, the first reinforcing plate 34 is arranged along the length extension direction of the column reinforcement 4 and the upper and lower ends of the first reinforcing plate 34 are correspondingly connected to the first connecting plate 32 and the second connecting plate 33.

[0034] The setting of the first reinforcing plate 34 effectively compensates for the problem that the column reinforcement 4 at the corresponding position of the steel beam is interrupted due to the setting of the steel beam, resulting in a decrease in the strength of the connection node. The first reinforcing plate 34 is connected between the first connecting plate 32 and the second connecting plate 33 and is arranged along the length extension direction of the column reinforcement 4, which can better solve the above problem.

[0035] In some embodiments of the present application, Figure 1 and Figure 5 As shown, the first connecting plate 32 and the second connecting plate 33 both include a first plate 321 arranged in the concrete beam 2, and the first plate 321 extends along the first direction to one end close to the steel column 1 and does not protrude from the concrete beam 2; and also include a second plate 322 connected between the first plate 321 and the steel column 1 and gradually widening from the first plate 321 toward the steel column 1. The first plate 321 and the second plate 322 are connected and arranged as a whole.

[0036] Figure 1 Beam width in Figure 2 The beam surface elevations in the figure are all the outer contour positions of the concrete beam 2 (formed by the beam longitudinal reinforcement 211, the steel beam web 31, the first connecting plate 32, the second connecting plate 33, the first reinforcing plate 34, the second reinforcing plate 35 and the pouring of concrete). In order to ensure the strength requirements of the structure, the edges of the first connecting plate 32 and the second connecting plate 33 with concrete should be covered with concrete of sufficient thickness. Since the first plate 321 is set in the concrete beam 2, and the second plate 322 is set in the steel concrete column (formed by the steel column 1, the column reinforcement unit, the first annular stirrup 5 and the pouring of concrete), the first plate 321 is set in the concrete beam 2, and the second plate 322 is set in the steel concrete column (formed by the steel column 1, the column reinforcement unit, the first annular stirrup 5 and the pouring of concrete). (formed after concrete is laid), the thickness of the concrete layer in the steel-framed concrete column is greater than the thickness of the concrete layer of the concrete beam 2. Therefore, according to the different thicknesses of the concrete layers, the width of the first plate 321 provided in the concrete beam 2 is set to be narrower, and the width of the second plate 322 provided in the steel-framed concrete column is set to be wider. While ensuring that the first plate 321 and the second plate 322 are covered by a concrete layer of sufficient thickness from the concrete edge, the area size of the connection between the first connecting plate 32, the second connecting plate 33 and the steel-framed column 1 is increased as much as possible.

[0037] In some embodiments of the present application, second reinforcing plates 35 perpendicularly connected to the steel beam web 31 are provided at the junction of the first plate 321 and the second plate 322 and at opposite ends of the steel beam web 31 along the second direction Y (the second reinforcing plates 35 are welded to the steel beam web 31, the first connecting plate 32, and the second connecting plate 33). The upper and lower ends of the second reinforcing plates 35 are correspondingly connected to the facing sides of the first connecting plate 32 and the second connecting plate 33. To improve the overall structural strength of the steel beam, the provision of the second reinforcing plates 35 at the junction of the first plate 321 and the second plate 322 can effectively compensate for the weakening of the structural strength caused by the narrowing of the width of the first connecting plate 32 (the second connecting plate 33) in the direction extending from the second plate 322 to the first plate 321.

[0038] In some embodiments of the present application, a plurality of first shear members 6 extending vertically and away from the first connecting plate 32 and the second connecting plate 33 are provided at intervals on opposite sides of the first connecting plate 32 and the second connecting plate 33; the first shear members 6 are shear bolts (diameter 19 mm, length 110 mm, shear bolt spacing 150*200 mm) and are connected to the first connecting plate 32 and the second connecting plate 33 by welding, so as to strengthen the reliable connection between the subsequently poured concrete and the supporting frame 3 and the effective transmission of force.

[0039] In some embodiments of the present application, a plurality of second shear members 7 extending along the second direction and away from the steel beam web 31 are provided at opposite ends of the steel beam web 31 in the second direction. The second shear members 7 are shear studs (with a diameter of 19 mm, a length of 110 mm, and a shear stud spacing of 200*200 mm) and are connected to the steel beam web 31 by welding, so as to strengthen the reliable connection between the subsequently poured concrete and the supporting frame 3 and the effective transmission of force.

[0040] In some embodiments of the present application, Figure 2 As shown, a partition 11 is horizontally provided at a position corresponding to the first connecting plate 32 and the second connecting plate 33 in the steel column 1 and is fitted with the inner wall of the steel column 1 (the partition 11 and the inner wall of the steel column 1 are connected by welding), and a casting hole 12 is provided along the thickness direction of the partition 11; the partition 11 is provided to provide reliable transmission of the force acting on the steel column 1 by the first connecting plate 32 and the second connecting plate 33, and at the same time, a casting hole 12 is provided through the partition 11 for pouring concrete.

[0041] In some embodiments of the present application, the ends of the first connecting plate 32 and the second connecting plate 33 close to the steel column 1 are set to be flush with the ends connected to the steel beam web 31 and the steel column 1, so that the first connecting plate 32 and the second connecting plate 33 facing the steel column 1 are connected and fixed to the steel column 1 by welding, thereby increasing the structural strength at the connection node.

[0042] In order to achieve a smooth transition of the force of the reinforced concrete beam to the steel beam and then to the steel column, the bending and shear bearing capacity of the steel beam should be as strong as the bearing capacity of the concrete beam. The cross-sectional height of the steel beam should not be less than 0.7 times the height of the concrete beam, the length of the steel beam should not be less than 1 / 4 of the beam span, and should not be less than 1.5 times the cross-sectional height of the concrete beam, nor less than the lap length of the first and second rows of beam longitudinal reinforcement 211. Because the beam longitudinal reinforcement 211 extends into the concrete beam for a long time, the protective layer thickness of the beam longitudinal reinforcement 21 should meet the requirements of the corresponding specifications; and the steel beam web 31 and the lower flange of the steel beam (the second connecting plate 33) should be provided with shear studs, and the upper flange of the steel beam (the first connecting plate 32) should be provided with shear studs; the steel beam and the steel column adopt full penetration butt welds to achieve equal strength connection

[0043] The working process of the present invention is as follows: the construction workers first process the bearing frame 3 and the steel column 1 respectively in the factory, and install them together with the steel column 1. Then the steel column 1 is transported to the construction site. The construction workers respectively weld the beam longitudinal reinforcement 211 located above the first connecting plate 32 and the second connecting plate 33 to the upper end surfaces of the first connecting plate 32 and the second connecting plate 33 and connect and fix them by welding (if the beam longitudinal reinforcement 211 located above the first connecting plate 32 and the second connecting plate 33 is vertically far away from the first connecting plate 32 and the second connecting plate 33, it can be bent so that the beam longitudinal reinforcement 211 can overlap the upper end surfaces of the first connecting plate 32 and the second connecting plate 33 to meet the welding requirements), and connect the beam longitudinal reinforcement 211 located below the first connecting plate 32 and the second connecting plate 33 to the anchor 8, thereby realizing a reliable connection between the concrete beam 2 and the bearing frame 3, and finally realizing the connection between the concrete beam 2 and the steel column 1.

[0044] In summary, the embodiment of the present invention provides a connection node between a concrete beam with a steel beam and a steel-framed concrete column. This solution is achieved by providing a steel beam web 31 in the concrete beam and providing a first connecting plate 32 located between the two groups of longitudinal reinforcement units 21 at the top of the beam and a second connecting plate 33 located between the two groups of longitudinal reinforcement units 21 at the bottom of the beam at the upper and lower ends of the steel beam web 31. Anchors 8 are provided on the lower end faces of the first connecting plate 32 and the second connecting plate 33, so that the beam longitudinal reinforcements 211 located at the top of the beam and at the bottom, and at the bottom of the beam are correspondingly connected to the anchors 8, and the beam longitudinal reinforcements 211 located at the top of the beam and at the top, and at the bottom of the beam and at the top are correspondingly connected to the upper end faces of the first connecting plate 32 and the second connecting plate 33. This better solves the problem in the prior art that the beam longitudinal reinforcements on the outside are difficult to bypass the steel frame column, or that it is difficult to pass through the steel frame column when the steel bars are relatively dense.

[0045] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
