Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0038] like Figures 1 to 3 As shown, a preferred embodiment of the present invention provides a connection structure for a steel column, truss, and steel beam, comprising a steel column 1. Multiple reinforcing plates 5 are arranged vertically and at intervals within the steel column 1. Each reinforcing plate 5 extends horizontally to the outer side of the steel column 1 on at least one side. Vertically arranged connecting plates 4 are fixedly connected to the edges of the reinforcing plates 5 extending to the outer side of the steel column 1. Each connecting plate 4 connects to the truss 2 and the steel beam 3, respectively. Each reinforcing plate 5 is horizontally opposite to at least one of the upper flange of the truss 2, the lower flange of the truss 2, the upper flange of the steel beam 3, and the lower flange of the steel beam 3. In this embodiment of the invention, the truss 2 and steel beam 3 are fixedly mounted on the connecting plate 4. The connecting plate 4 is fixedly connected to multiple reinforcing plates 5 on the steel column 1. Each reinforcing plate 5 is horizontally aligned with the upper and lower flanges of the truss 2 and steel beam 3, ensuring continuous force transmission in the connection structure and enhancing its load-bearing capacity. This achieves a reliable connection between the truss 2, steel beam 3, and steel column 1. The connecting plate 4 is located at the edge of the steel-concrete column, minimizing contact with the vertical reinforcing bars of the steel-concrete column. This embodiment of the invention features a simple and reliable connection, direct force transmission, and good load-bearing capacity. It solves the technical problem in the prior art where no node structure connects the truss 2, steel beam 3, and steel column 1, making a reliable connection between the truss 2, steel beam 3, and steel column impossible.

[0039] Specifically, such as Figures 1 to 3As shown, the reinforcing plates 5 include a first reinforcing plate 5a, a second reinforcing plate 5b, a third reinforcing plate 5c, a fourth reinforcing plate 5d and a fifth reinforcing plate 5e, edges of the first reinforcing plate 5a, the second reinforcing plate 5b and the third reinforcing plate 5c all extend horizontally to pass through the steel column 1; the fourth reinforcing plate 5d and the fifth reinforcing plate 5e both include a plurality of inner reinforcing plates 8 located inside the steel column 1 and outer reinforcing plates 9 located between the steel column 1 and the connecting plate 4, each inner reinforcing plate 8 is fixedly connected with the steel column 1, and two ends of each outer reinforcing plate 9 are fixedly connected with the steel column 1 and the connecting plate 4 respectively.

[0040] Specifically, as shown, Figures 1 to 3 The connecting plate 4 includes a first connecting plate 4a, a second connecting plate 4b, a third connecting plate 4c and a fourth connecting plate 4d.

[0041] The first side of the first reinforcing plate 5a, the first side of the second reinforcing plate 5b and the first side of the third reinforcing plate 5c and the outer reinforcing plate 9 of the fifth reinforcing plate 5e are fixedly connected with the first connecting plate 4a at the same time; the second side of the first reinforcing plate 5a, the second side of the second reinforcing plate 5b and the second side of the third reinforcing plate 5c are fixedly connected with the second connecting plate 4b at the same time, and the second side is arranged opposite to the first side; the third side of the first reinforcing plate 5a and the outer reinforcing plate 9 of the third side of the fourth reinforcing plate 5d are fixedly connected with the third connecting plate 4c at the same time, and the fourth side of the first reinforcing plate 5a and the outer reinforcing plate 9 of the fourth side of the fourth reinforcing plate 5d are fixedly connected with the fourth connecting plate 4d at the same time, and the third side is arranged opposite to the fourth side.

[0042] The truss 2 is fixedly installed on the first connecting plate 4a, and the truss 2 includes a top chord 2a and a diagonal web 2b; the steel beam 3 includes a first steel beam 3a, a second steel beam 3b and a third steel beam 3c, the first steel beam 3a is fixedly installed on the second connecting plate 4b, the second steel beam 3b is fixedly installed on the third connecting plate 4c, and the third steel beam 3c is fixedly installed on the fourth connecting plate 4d.

[0043] In the embodiment of the utility model, the first reinforcing plate 5a, the second reinforcing plate 5b and the third reinforcing plate 5c extend horizontally to the outside of the steel column 1 and pass through the steel column 1, while the fourth reinforcing plate 5d and the fifth reinforcing plate 5e are fixedly connected with the steel column 1 and do not cut off the steel column 1, thus the integrity of the steel column 1 is reserved.

[0044] Generally, the span of the truss 2 is large, the bending moment of the fixed end of the truss 2 and the fixed end of the first steel beam 3a on the opposite side thereof is large, and therefore the first reinforcing plate 5a, the second reinforcing plate 5b and the third reinforcing plate 5c are penetrated through the truncated steel column 1, two opposite sides of the first reinforcing plate 5a, the second reinforcing plate 5b and the third reinforcing plate 5c are fixedly connected with the first connecting plate 4a and the second connecting plate 4b respectively, the bending moment of the truss 2 is directly transmitted to the second connecting plate 4b through the first reinforcing plate 5a, the second reinforcing plate 5b and the third reinforcing plate 5c, and is counteracted by the bending moment of the first steel beam 3a on the second connecting plate 4b, so that the moment balance of the connecting structure in the direction of the truss 2 and the first steel beam 3a is realized. The penetrated first reinforcing plate 5a, the second reinforcing plate 5b and the third reinforcing plate 5c also realize the reliable connection of the first connecting plate 4a and the second connecting plate 4b with the steel column 1.

[0045] The more the reinforcing plates 5 of the truncated steel column 1 are, the worse the integrity of the steel column 1 is, and the connection between the steel column and the reinforcing plates will increase more welds, which is not only inconvenient for construction, but also will produce large welding deformation and stress concentration area, which is not conducive to the overall stress of the connecting structure. Therefore, the fourth reinforcing plate 4d and the fifth reinforcing plate 4e are not penetrated through the steel column 1 in the lower flange of the second steel beam 3b, the third steel beam 3c and the inclined web member 2b which are relatively small in stress.

[0046] In the embodiment of the utility model, each connecting plate 4 is vertically arranged on the outer side of the steel column 1, which avoids the vertical steel bars of the steel reinforced concrete column to the maximum extent, and the reinforcing plate 5 simultaneously connects multiple connecting plates 4, which creates good conditions for the anchoring of the connecting plate 4 in the steel reinforced concrete, ensures the reliable connection of each connecting plate 4 with the steel column 1, and lays a foundation for the reliable connection of the truss, the steel beam and the steel reinforced concrete column. The arrangement of the connecting plate and the reinforcing plate also enhances the load bearing capacity of the connecting structure.

[0047] When the truss 2 and the steel beam 3 intersect at the same steel reinforced concrete column, multiple reinforcing plates 5 need to be added in the horizontal and vertical directions of the node area. The node area generally requires full penetration and equal strength welding, when the number of reinforcing plates 5 is too large, on the one hand, it will seriously affect the welding and detection space, on the other hand, it will produce large welding deformation and stress concentration area, which is not conducive to the overall stress. At the same time, considering the collision problem of the reinforcing plate 5 and the steel bars of the steel reinforced concrete column, holes need to be opened on the reinforcing plate or reinforcing plates or sleeves need to be added, and too many reinforcing plates will lead to the presence of more semi-closed small cavities in the node area, which is not conducive to the pouring of concrete.

[0048] In order to solve the above problems, as shown in Figures 1 to 3 The first reinforcing plate 5a is horizontally opposite to the upper flange of the top chord 2a, the second reinforcing plate 5b is horizontally opposite to the lower flange of the top chord 2a, and the fifth reinforcing plate 5e is horizontally opposite to the lower flange of the inclined web member 2b.

[0049] The first reinforcing plate 5a is horizontally opposite to the upper flange of the first steel beam 3a, and the third reinforcing plate 5c is horizontally opposite to the lower flange of the first steel beam 3a.

[0050] In the embodiment of the utility model, the cross section height of the first steel beam 3a is greater than the cross section height of the upper chord 2a, and the cross section height of the upper chord 2a is greater than the cross section height of the second steel beam 3b. The reinforcing plate 5 is horizontally aligned with the upper and lower flanges of the upper chord 2a, the lower flange of the diagonal web 2b, the upper and lower flanges of the first steel beam and the upper and lower flanges of the second steel beam, which ensures the force transmission continuity of the truss 2 and the steel beams 3 at the steel column 1 and improves the bearing capacity of the connecting structure. The reinforcing plate at the upper flange of the diagonal web 2b is not provided, the upper flange of the diagonal web 2b is fixed on the first connecting plate 4a, the force borne by the upper flange of the diagonal web is transmitted to the reinforcing plates 5 by the first connecting plate 4a, and the reinforcing plates 5 transmit the force to the upper and lower flanges of the first steel beam 3a, so that the force balance is realized.

[0051] It should be noted that when the cross section height of the second steel beam 3b and the third steel beam 3c is relatively small compared with the cross section height of the upper chord 2a, the lower flanges of the second steel beam 3b and the third steel beam 3c can be horizontally opposite to the second reinforcing plate 5b by using the variable cross section method, so that the fourth connecting plate 5d is omitted.

[0052] Further, as shown in Figures 2 to 9 , the steel column 1 comprises a first web 1e and a second web 1f fixedly connected perpendicularly to the first web 1e, the two ends of the first web 1e are respectively fixedly provided with a first flange plate 1a and a second flange plate 1b perpendicularly, and the two ends of the second web 1f are respectively fixedly provided with a third flange plate 1c and a fourth flange plate 1d perpendicularly.

[0053] The first connecting plate 4a is arranged in parallel and interval with the first flange plate 1a, the second connecting plate 4b is arranged in parallel and interval with the second flange plate 1b, the third connecting plate 4c is arranged in parallel and interval with the third flange plate 1c, and the fourth connecting plate 4d is arranged in parallel and interval with the fourth flange plate 1d. That is, the first side corresponds to the direction of the first flange plate 1a, the second side corresponds to the direction of the second flange plate 1b, the third side corresponds to the direction of the third flange plate 1c, and the fourth side corresponds to the direction of the fourth flange plate 1d.

[0054] Further, in order to strengthen the connection between the connecting plate 4 and the steel column 1, as shown in Figures 1 to 3 , Figures 5 to 9As shown, vertical stiffening plates 7 are arranged between the first connecting plate 4a and the first flange plate 1a, between the second connecting plate 4b and the second flange plate 1b, between the third connecting plate 4c and the third flange plate 1c, and between the fourth connecting plate 4d and the fourth flange plate 1d.

[0057] In the embodiment of the utility model, the connecting plate 4 and the steel column 1 are fixedly connected through the reinforcing plate 5 and the vertical stiffening plate 7, not only the connection between the connecting plate 4 and the steel column 1 is enhanced, but also the load on the connecting plate 4 can be transmitted to the web plate of the steel column 1 through the vertical stiffening plate 7, then transmitted to the connecting plate 4 on the opposite side through the web plate, and offset with the load on the connecting plate 4 on the opposite side, wherein the steel column 1 does not directly bear the load, only transmits the load, and the load bearing of the whole connecting joint is realized by the moment balance between the two opposite structure members. Wherein, the vertical stiffening plate 7 and the corresponding web plate have the same thickness, in order to better realize the load transmission.

[0058] In order to guarantee the anchoring of the vertical steel reinforcement of the steel reinforced concrete column in the joint connecting area, like Figures 1 to 3 , Figure 9As shown, the top of the first reinforcing plate 5a between the first connecting plate 4a and the first flange plate 1a, the top of the first reinforcing plate 5a between the second connecting plate 4b and the second flange plate 1b, the top of the first reinforcing plate 5a between the third connecting plate 4c and the third flange plate 1c, and the top of the first reinforcing plate 5a between the fourth connecting plate 4d and the fourth flange plate 1d are provided with column main reinforcement connectors 6 for connecting column main reinforcements.

[0059] In order to ensure the compactness of the connection node area during pouring, as shown, Figures 1 to 9 As shown, the middle part of each reinforcing plate 5 is provided with a round hole 10 for concrete flow during pouring.
