Description

Technical Field

[0001] This utility model relates to the field of mechanical energy storage technology, specifically to a steel-concrete composite column-frame beam-track beam connection node based on mechanical energy storage. Background Technology

[0002] The track beam of a mechanical energy storage device is a special track structure that incorporates the principles of mechanical energy storage technology, facilitating the storage and release of energy. The track beam employs an L-shaped cross-section design, allowing it to support the transport trolley horizontally and the energy storage blocks vertically. Therefore, the connection nodes between the L-shaped track beam and the steel-concrete composite columns and frame beams in the mechanical energy storage device must ensure sufficient load-bearing capacity and stability.

[0003] The connection between reinforced concrete beams and concrete-filled steel tubular columns should be simple in structure, have clear force transmission, good integrity, be safe and reliable, economical and reasonable, and convenient to construct. Furthermore, in seismic design, the failure of the joint should not precede the failure of the connected components. In the existing case, a track beam acts on a frame beam, which connects to a concrete-filled steel tubular column; this area is a cast-in-place joint. Due to the dense longitudinal reinforcement and stirrups of the track beam and frame beam, the joint area presents difficulties in reinforcement binding and concrete pouring. The longitudinal reinforcement of the beam needs to be welded to the concrete-filled steel tubular column, resulting in a large amount of steel used in the joint. Moreover, cold processing of large-diameter steel bars on-site is difficult, making it hard to guarantee construction accuracy and potentially affecting the building's quality. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model provides a steel-concrete composite column-frame beam-track beam connection node based on mechanical energy storage. Under the premise of meeting safety and reliability requirements, it has a simple structure and is convenient to manufacture and construct.

[0005] To achieve the above technical objectives, this utility model adopts the following technical solution: a steel-concrete composite column-frame beam-track beam connection node based on mechanical energy storage, comprising: a track beam, a frame beam, a steel-concrete composite column, and a column cap. The steel-concrete composite column is arranged along the height direction of the mechanical energy storage device. The bottom surface of each floor of the mechanical energy storage device intersects with the steel-concrete composite column at a longitudinally arranged frame beam and a transversely arranged track beam. A track beam is provided on each side of the steel-concrete composite column. The intersection of the steel-concrete composite column, the frame beam, and the track beam is fixedly connected by the column cap, forming a steel-concrete composite column-frame beam-track beam connection node.

[0006] Furthermore, the track beam is L-shaped and is fixedly connected by an upper track beam and a lower track beam. The cross-sectional width of the lower track beam is greater than that of the upper track beam. The lower track beam is used for the passage of RGV trolleys, and the upper track beam is used for placing energy storage blocks.

[0007] Furthermore, both the upper and lower track beams are provided with longitudinal reinforcement bars and closed stirrups. The longitudinal reinforcement bars and closed stirrups located in the lower part of the upper track beam are tied and fixed to the adjacent closed stirrups in the lower track beam, and the upper and lower track beams are fixed by concrete pouring.

[0008] Furthermore, the column cap is provided with an upper ring bar, a lower ring bar, a U-shaped stirrup, and a waist bar. The upper ring bar is located at the upper inner end of the column cap, and the lower ring bar is located at the lower inner end of the column cap. A U-shaped stirrup is provided between the upper and lower ring bars. The U-shaped stirrup is located at the upper track beam, and a waist bar is provided inside the U-shaped stirrup.

[0009] Furthermore, the U-shaped stirrups of the column cap are tied and fixed to the longitudinal reinforcement of the track beam, and the upper and lower ring bars of the column cap are tied and fixed to the closed stirrups in the upper and lower track beams. The column cap is fixed to the upper track beam by concrete pouring.

[0010] Furthermore, the opening of the U-shaped stirrup of the column cap is welded and fixed to the outer wall of the steel-concrete composite column.

[0011] Furthermore, the edge of the column cap is also provided with Y-direction reinforcing bars, which overlap with the longitudinal reinforcing bars of the track beam in the upper track beam.

[0012] Furthermore, the column cap is also provided with an annular steel bracket, which is sleeved on the steel-concrete composite column and welded and fixed to the outer wall of the steel-concrete composite column.

[0013] Furthermore, the annular steel bracket extends into the upper track beam and is located at the elevation of the lower track beam.

[0014] Furthermore, the annular steel bracket is composed of an upper reinforcing ring, a lower reinforcing ring, and radially evenly distributed ribs. The ribs are arranged between the upper and lower reinforcing rings, and the ribs are fixed to the upper reinforcing ring and the lower reinforcing ring by welding.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This invention relates to a mechanical energy storage-based steel-concrete composite column-frame beam-track beam connection node. A column cap is installed at the junction of the steel-concrete composite column, frame beam, and track beam to form the connection node. This eliminates the need for the reinforcing bars in the track beam to pass through the interior of the steel-concrete composite column, avoiding the need for numerous longitudinal reinforcements in the track beam to connect to the steel-concrete composite column and reducing the amount of welding work required in the connection area. A ring-shaped steel bracket is installed inside the column cap and welded to the outer wall of the steel-concrete composite column. This can be prefabricated in the factory, saving on-site construction work. The ring-shaped steel bracket effectively reduces deformation and torsion of the steel-concrete composite column, maintaining structural stability. Simultaneously, the upper and lower ring reinforcements of the column cap, the U-shaped stirrups of the column cap, and the ring-shaped steel bracket jointly bear the transmission of bending moment and shear force in the connection area, while increasing the area of ​​the core area of ​​the connection and improving the load-bearing capacity of the connection. Therefore, this mechanical energy storage-based steel-concrete composite column-frame beam-track beam connection node, while meeting safety and reliability requirements, has the advantages of simple structure and convenient manufacturing and construction.

Detailed Implementation

[0025] The technical solution of this utility model will be further explained below with reference to the accompanying drawings.

[0026] like Figure 1 This is a schematic diagram of the plan layout of a mechanical energy storage device. The device includes: a track beam 1, a frame beam 2, a steel-concrete composite column 3, and a column cap 4. The steel-concrete composite column 3 is arranged along the height of the device. At the junction of the bottom surface of each floor and the steel-concrete composite column 3, the longitudinal frame beam 2 and the transverse track beam 1 are arranged, with one track beam 1 on each side of the steel-concrete composite column 3. The junctions of the steel-concrete composite column 3, frame beam 2, and track beam 1 are fixedly connected by the column cap 4, forming a steel-concrete composite column-frame beam-track beam connection node. This design eliminates the need for the reinforcing bars in the track beam 1 to pass through the interior of the steel-concrete composite column 3, avoiding the need for a large number of longitudinal reinforcing bars in the track beam 1 to connect to the steel-concrete composite column 3, thus reducing the amount of welding work in the joint area. Furthermore, this utility model, based on a mechanical energy storage steel-concrete composite column-frame beam-track beam connection node, offers advantages such as simple structure, ease of manufacturing, and convenient construction while meeting safety and reliability requirements.

[0027] like Figure 2 In this utility model, the track beam 1 is L-shaped and is fixedly connected by an upper track beam 5 and a lower track beam 6. The cross-sectional width of the lower track beam 6 is greater than that of the upper track beam 5. The lower track beam 6 is used for the passage of the RGV trolley, and the distance between two adjacent lower track beams 6 is less than the width of the RGV trolley. The upper track beam 5 is used to place the energy storage block, and the distance between two adjacent upper track beams 5 is less than the width of the energy storage block. The height of the lower track beam 6 is less than the height of the upper track beam 5 to ensure that the RGV trolley will not collide with the energy storage block when running on the lower track beam 6.

[0028] like Figure 7 Both the upper track beam 5 and the lower track beam 6 are provided with longitudinal reinforcement 11 and closed stirrups. The longitudinal reinforcement 11 and closed stirrups of the track beam located in the lower part of the upper track beam 5 are tied and fixed with the adjacent closed stirrups in the lower track beam 6. The upper track beam 5 and the lower track beam 6 are fixed by concrete pouring.

[0029] like Figure 3-5In this utility model, the column cap 4 is provided with an upper ring bar 12, a lower ring bar 13, a U-shaped stirrup 14, and a waist bar 15. The upper ring bar 12 is located at the upper inner end of the column cap 4, and the lower ring bar 13 is located at the lower inner end of the column cap 4. The U-shaped stirrup 14 is provided between the upper ring bar 12 and the lower ring bar 13. The U-shaped stirrup 14 is located at the upper track beam 5, and the waist bar 15 is located on the inner side of the U-shaped stirrup 14. The opening of the U-shaped stirrup 14 is welded and fixed to the outer wall of the steel pipe concrete column 3, thereby forming a solid skeleton and strengthening the structural integrity of the column cap skeleton. The U-shaped stirrup 14 improves the shear strength of the oblique section of the node. Furthermore, the U-shaped stirrups 14 of the column cap are tied and fixed to the longitudinal reinforcement 11 of the track beam, and the upper ring reinforcement 12 and the lower ring reinforcement 13 of the column cap are tied and fixed to the closed stirrups in the upper track beam 5 and the lower track beam 6. The column cap 4 is fixed to the upper track beam 5 by concrete pouring, so that the reinforcement in the track beam 1 does not need to pass through the interior of the steel pipe concrete column 3, reducing the amount of reinforcement welding work in the joint area.

[0030] In one technical solution of this utility model, the edge of the column cap 4 is also provided with column cap Y-direction steel bar 16, which overlaps with the longitudinal bar 11 of the track beam in the upper track beam 5 and is cast in place with concrete to form an integral whole. This avoids a large number of longitudinal bars in the upper track beam 5 being connected to the steel pipe concrete column 3, thereby effectively reducing the construction difficulty, speeding up the construction progress, and ensuring the rigidity of the connection node, ensuring that the connection node can effectively transmit bending moment and shear force.

[0031] like Figure 3 The column cap 4 also includes a ring-shaped steel bracket 7, which is fitted onto the steel-concrete composite column 3 and welded to the outer wall of the column 3. The ring-shaped steel bracket 7 extends into the upper track beam 5 and is located at the elevation of the lower track beam 6. This steel-concrete composite column-frame beam-track beam connection node, through the upper ring reinforcement 12, lower ring reinforcement 13, U-shaped stirrups 14, and ring-shaped steel bracket 7 of the column cap, bears the transmission of bending moment and shear force in the node area, while increasing the area of ​​the core area of ​​the node and improving the load-bearing capacity of the node.

[0032] like Figure 6 In this invention, the annular steel bracket 7 consists of an upper reinforcing ring 8, a lower reinforcing ring 9, and radially distributed ribs 10. The ribs 10 are arranged between the upper reinforcing ring 8 and the lower reinforcing ring 9, and are fixed to the upper reinforcing ring 8 and the lower reinforcing ring 9 by fillet welds. The upper reinforcing ring 8, the lower reinforcing ring 9, and the ribs 10 are also fixed to the outer wall of the steel-concrete composite column 3 by fillet welds, thus bearing the external shear force of the steel pipe in the steel-concrete composite column 3. Furthermore, both the annular steel bracket 8 and the steel pipe of the steel-concrete composite column 3 can be prefabricated in the factory and installed on-site, thereby reducing the amount of on-site construction work.

[0033] In summary, the steel-concrete composite column-frame beam-track beam connection node based on mechanical energy storage of this utility model has the advantages of simple structure, convenient manufacturing and construction, while meeting the requirements of safety and reliability.
