Description

Technical Field

[0001] This invention relates to the field of steel column installation, and more specifically to a reinforcement structure for dense connection between steel columns and foundation plates. Background Technology

[0002] "Dense connection treatment of steel columns and foundation plate" usually appears in steel structure buildings, industrial plants, tall structures (such as towers and chimneys) or heavy equipment foundations. When multiple steel columns (or lattice columns, steel-concrete composite columns) are concentrated and anchored to the same concrete foundation in a small area, a dense connection node is formed. This structure places high demands on design, construction and load-bearing performance.

[0003] However, in conventional techniques, after the steel columns and the foundation plate are densely connected, it is not possible to effectively strengthen the structure, thus affecting the stability of the connection between the steel columns and the foundation plate.

[0004] Therefore, it is necessary to invent a reinforcement structure that involves dense connection between steel columns and the foundation plate. Summary of the Invention

[0005] Therefore, the present invention provides a reinforcement structure with dense connection between steel columns and foundation plate to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a reinforcement structure for densely connecting steel columns and a foundation plate, comprising several steel columns and a foundation plate, wherein several sets of load-bearing platforms are fixed to the top of the foundation plate, each set consisting of two load-bearing platforms, and a steel column web is fixed between each pair of load-bearing platforms in the same set. The bottom of the steel column is fixed to the top of the load-bearing platform and the top of the steel column web, and flange plates are fixed to both ends of the steel column web. Connecting plates are fixed to the ends of the flange plates, and an X-axis reinforcement component is fixed between the connecting plates, the load-bearing platforms, and the foundation plate. A Y-axis reinforcement component is fixed between the steel column web and the foundation plate, and a densely connected component is fixed to the foundation plate. Both the X-axis reinforcement component and the Y-axis reinforcement component are fixedly connected to the densely connected component.

[0007] Preferably, the X-direction reinforcing component includes a plurality of X-direction reinforcing bars, the ends of which all penetrate the load-bearing platform, and the ends of which are welded and fixed to the connecting plate.

[0008] Preferably, the X-direction reinforcing component further includes two X-direction bottom plate reinforcing bars, the middle of which passes through the web of the steel column and the edge of the load-bearing platform.

[0009] Preferably, the Y-direction reinforcing component includes a plurality of first through holes and a plurality of second through holes, which are symmetrically and longitudinally formed on the two flange plates.

[0010] Preferably, several first through holes and second through holes are longitudinally penetrating and fixed with first Y-direction reinforcing bars, several ordinary studs are symmetrically fixed at the front and rear ends of the steel column web, and several prefabricated studs with hooks are also symmetrically fixed at the front and rear ends of the steel column web.

[0011] Preferably, each of the ends of the ordinary studs is longitudinally fixed with a second Y-direction reinforcing bar, and each of the prefabricated studs with hooks is hooked to a third Y-direction reinforcing bar.

[0012] Preferably, the dense connection assembly includes a plurality of X-direction connecting steel bars, a plurality of Y-direction connecting steel bars and a plurality of Z-direction connecting steel bars, the intersection points of the plurality of X-direction connecting steel bars, the plurality of Y-direction connecting steel bars and the plurality of Z-direction connecting steel bars are fixed to each other, and the bottom ends of the plurality of Z-direction connecting steel bars are fixed to the top of the foundation plate.

[0013] Preferably, the plurality of X-direction connecting steel bars, the plurality of Y-direction connecting steel bars and the plurality of Z-direction connecting steel bars are fixedly connected to each other by a plurality of separate combined stirrups and a plurality of separate combined waist bars.

[0014] Preferably, the intersection points between the plurality of X-direction reinforcing bars and adjacent Y-direction connecting bars and adjacent Z-direction connecting bars are fixed to each other, and the intersection points between the two X-direction bottom plate reinforcing bars and adjacent Y-direction connecting bars and adjacent Z-direction connecting bars are fixed to each other.

[0015] Preferably, the intersection points between a plurality of the first Y-direction reinforcing bars and the adjacent X-direction connecting bars and the adjacent Z-direction connecting bars are fixed to each other; the intersection points between a plurality of the second Y-direction reinforcing bars and the adjacent X-direction connecting bars and the adjacent Z-direction connecting bars are fixed to each other; and the intersection points between a plurality of the third Y-direction reinforcing bars and the adjacent X-direction connecting bars and the adjacent Z-direction connecting bars are fixed to each other.

[0016] The beneficial effects of this invention are: 1. Optimize the arrangement of the reinforcing bars passing through the web of the steel column to meet the requirements of continuous installation, and supplement and reinforce the web of the steel column to strengthen the structure, thereby effectively increasing the stability of the connection between the steel column and the foundation plate. Add connecting plates to the flange plates of the steel columns and weld them to the X-direction reinforcing bars; After the design unit confirmed the optimized drawings for the connection between the steel column and the foundation plate reinforcement, the stirrups and web reinforcement were designed as separate composite stirrups. The foundation stirrups and web reinforcement were divided into several U-shaped sections that passed through the steel section and were welded into closed stirrups to facilitate later implementation. The bottom plate reinforcement closest to the edge of the steel column is inclined to avoid the web and flange of the steel column, thus reducing the number of openings and welding points in the steel column. For the reinforcing bars penetrating the web of the steel column, an additional steel mesh formed by X-direction connecting reinforcing bars, Y-direction connecting reinforcing bars, and Z-direction connecting reinforcing bars and stirrups are added below the intermediate layer for optimized arrangement, and the penetration position of the steel column is reinforced. The steel column flange plate is reinforced with a connecting plate and welded to the X-direction reinforcing steel. A connecting plate is added at the flange plate position so that the reinforcing steel is welded and fixed to the flange plate and the connecting plate. The reinforcement effect of the steel column web plate and the fixing effect of the flange plate and connecting plate at the reinforced part are determined. Attached Figure Description

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Please refer to the appendix. Figures 1-5 The present invention provides a reinforcement structure for dense connection between steel columns and a foundation plate, comprising several steel columns 1 and a foundation plate 2. Several sets of load-bearing platforms 3 are fixed to the top of the foundation plate 2, with two load-bearing platforms 3 in each set. A steel column web 4 (e.g., ...) is fixed between each pair of load-bearing platforms 3 in the same set. Figure 1-2As shown), the bottom of the steel column 1 is fixed to the top of the load-bearing platform 3 and the top of the steel column web 4. Flange plates 5 are fixed to both ends of the steel column web 4. Connecting plates 6 are fixed to the ends of the flange plates 5. An X-direction reinforcing component is fixed between the connecting plate 6, the load-bearing platform 3 and the base plate 2. A Y-direction reinforcing component is fixed between the steel column web 4 and the base plate 2. A dense connection component is fixed on the base plate 2. The X-direction reinforcing component and the Y-direction reinforcing component are both fixedly connected to the dense connection component. Furthermore, the X-direction reinforcing component includes several X-direction reinforcing bars 7, the ends of which all penetrate the load-bearing platform 3, and the ends of which are welded and fixed to the connecting plate 6. The X-direction reinforcing component also includes two X-direction bottom plate reinforcing bars 8, the middle of which passes through the edge of the steel column web 4 and the load-bearing platform 3. Specifically, under the reinforcing effect of the several X-direction reinforcing bars 7, the flange plate 5 of the steel column 1 can be connected to the X-direction reinforcing bars 7 by adding a connecting plate 6, so that the X-direction reinforcing bars 7 are welded and fixed to the flange plate 5 and the connecting plate 6, thus determining the reinforcement effect of the steel column web 4 and the fixing effect of the flange plate 5 and the connecting plate 6 at the reinforced part. Under the action of the X-direction bottom plate reinforcing bars 8, the bottom plate reinforcing bars closest to the edge of the steel column 1 can be inclined to avoid the steel column web 4 and flange plate 5, thereby reducing the number of openings and welding points in the steel column 1. Furthermore, the Y-direction reinforcing component includes several first through holes 9 and several second through holes 10. The several first through holes 9 and several second through holes 10 are symmetrically and longitudinally opened on the two flange plates 5. The several first through holes 9 and several second through holes 10 are longitudinally penetrated and fixed with first Y-direction reinforcing bars 11. Several ordinary studs 12 are symmetrically fixed at the front and rear ends of the steel column web plate 4. Several prefabricated studs with hooks 13 are also symmetrically fixed at the front and rear ends of the steel column web plate 4. The ends of several ordinary studs 12 are longitudinally fixed with second Y-direction reinforcing bars 14. The ends of prefabricated studs with hooks 13 are hooked with third Y-direction reinforcing bars 16 through hooks 15. Specifically, under the reinforcing effect of several first Y-direction reinforcing bars 11 and second Y-direction reinforcing bars 14, the steel column web plate 4 can be effectively longitudinally welded and fixed, and the steel column web plate reinforcement 4 of the reinforcement treatment part is determined. Furthermore, the dense connection assembly includes several X-direction connecting steel bars 17, several Y-direction connecting steel bars 18, and several Z-direction connecting steel bars 19. The intersection points of the several X-direction connecting steel bars 17, several Y-direction connecting steel bars 18, and several Z-direction connecting steel bars 19 are fixed to each other. The bottom ends of the several Z-direction connecting steel bars 19 are fixed to the top of the foundation plate 2. The several X-direction connecting steel bars 17, several Y-direction connecting steel bars 18, and several Z-direction connecting steel bars 19 are fixedly connected to each other by several separate combined stirrups 20 and several separate combined waist bars 21. Specifically, under the dense welding and fixing action of the several X-direction connecting steel bars 17, several Y-direction connecting steel bars 18, and several Z-direction connecting steel bars 19, the steel bars penetrating the web plate 4 of the steel column can be optimized by adding a steel mesh formed by X-direction connecting steel bars 17, Y-direction connecting steel bars 18, and Z-direction connecting steel bars 19 below the intermediate layer, as well as separate combined stirrups 20 and separate combined waist bars 21, and the penetration position of the steel column 1 is reinforced. Furthermore, the intersection points between several X-direction reinforcing bars 7 and adjacent Y-direction connecting bars 18 and adjacent Z-direction connecting bars 19 are fixed to each other, and the intersection points between two X-direction bottom plate reinforcing bars 8 and adjacent Y-direction connecting bars 18 and adjacent Z-direction connecting bars 19 are fixed to each other. Specifically, the above structure allows several X-direction reinforcing bars 7 and two X-direction bottom plate reinforcing bars 8 to be welded and fixed on the reinforcing mesh formed by X-direction connecting bars 17, Y-direction connecting bars 18 and Z-direction connecting bars 19 to ensure the reinforcement effect. Furthermore, the intersection points between a number of first Y-direction reinforcing bars 11 and adjacent X-direction connecting bars 17 and adjacent Z-direction connecting bars 19 are fixed to each other; the intersection points between a number of second Y-direction reinforcing bars 14 and adjacent X-direction connecting bars 17 and adjacent Z-direction connecting bars 19 are fixed to each other; and the intersection points between a number of third Y-direction reinforcing bars 16 and adjacent X-direction connecting bars 17 and adjacent Z-direction connecting bars 19 are fixed to each other. Specifically, the above structure allows the number of first Y-direction reinforcing bars 11, the number of second Y-direction reinforcing bars 14, and the number of third Y-direction reinforcing bars 16 to be welded and fixed on the reinforcing mesh formed by the X-direction connecting bars 17, Y-direction connecting bars 18, and Z-direction connecting bars 19 to ensure the reinforcement effect. In summary, this reinforcement structure optimizes the arrangement of the reinforcing bars passing through the web 4 of the steel column, ensuring that it meets the requirements for continuous installation. It also provides supplementary reinforcement to the web 4 of the steel column, thus strengthening the structure and effectively increasing the stability of the connection between the steel column 1 and the foundation plate 2. Furthermore, after the design unit confirms the optimized drawings of the reinforcement connection between the steel column 1 and the foundation plate 2, the stirrups and web reinforcement are designed as separate composite stirrups. The foundation stirrups and web reinforcement are divided into several U-shaped sections that pass through the steel section and are welded into closed stirrups for easy implementation later.
