Description

Technical Field

[0001] This application relates to the field of architecture, and more specifically, to a TOD (Transit-Oriented Development) overpass conversion system and TOD buildings. Background Technology

[0002] In TOD (transit-oriented development) architecture, development is generally divided into two stages. The first stage involves constructing the transportation hub. After completion, the hub's roof slab is used as the ground surface for three-dimensional piling and then the land is put up for auction. The winning bidder then undertakes the second stage development of the depot. In this model, during the first stage construction of the hub, there is no clearly defined owner for the superstructure development, making it impossible to fully determine the superstructure design. Therefore, the structural design is based on a preliminary plan, with some column heads reserved for later connection.

[0003] Because the entire project takes a long time to build, the business formats and models of the above-ground development will change over time. After the hub is completed and put into operation, it is impossible to carry out large-scale reinforcement and renovation due to changes in the above-ground plan. Therefore, the flexibility of the above-ground development project is limited and the economic benefits of the project are low.

[0004] Therefore, how to match the development of the upper cover to connect the lower structure (i.e., the hub part) is the technical problem that this application needs to solve. Utility Model Content

[0005] In view of this, this application proposes a conversion system for the TOD top cover to facilitate matching of the top cover structure and the lower structure.

[0006] This application provides a conversion system for a TOD (Transit-Oriented Development) roof, wherein the conversion system includes a substructure, a conversion platform, and a hinged support. The hinged support is aligned with the vertical components of the substructure. The conversion platform is supported on the vertical components by the hinged support. The conversion platform includes a conversion beam, and the conversion beam is provided with conversion beam support legs corresponding to the hinged support and connected to the hinged support by the conversion beam support legs.

[0007] Optionally, the hinged support includes a spherical support.

[0008] Optionally, the conversion platform includes a column conversion layer or a wall conversion layer.

[0009] Optionally, the transfer beam includes reinforcing ribs corresponding to the support legs of the transfer beam.

[0010] Optionally, the hinged support includes an upper support plate, the transfer beam support leg is welded to the upper support plate, the hinged support includes a support base plate, and the lower structure is fixed to the support base plate.

[0011] Optionally, the lower structure includes a reserved reinforced concrete column head, which is fixed to the support base plate. The conversion system includes a first reinforcing structure that connects the reinforced concrete column head and the support base plate around the reinforced concrete column head. The first reinforcing structure includes a hoop plate that surrounds the reinforced concrete column head and connects to the support base plate, a vertical stiffening rib that connects the hoop plate and the support base plate, a circumferential stiffening rib that extends radially outward from the hoop plate, and a first grouting filler portion that fills the space between the hoop plate and the reinforced concrete column head.

[0012] Optionally, the lower structure includes a reserved steel column head, the support base plate is fixed to the steel column head, the bottom of the support base plate is provided with grid-like longitudinal and transverse stiffening ribs, and the steel column head is filled with a second grouting filler.

[0013] Optionally, the substructure includes a post-anchored shear structure, which includes shear reinforcement, shear keys, stirrups, and cast-in-place column piers. The shear reinforcement and shear keys are respectively fixed to the support base plate.

[0014] This application also provides a TOD building, wherein the TOD building includes the TOD superstructure conversion system of this application and a superstructure structure disposed above the conversion platform.

[0015] According to the technical solution of this application, the vertical and horizontal forces of the superstructure are transmitted to the aligned vertical members and then to the foundation through hinged supports, while simultaneously releasing bending moments. The superstructure can be flexibly arranged via a conversion platform, reducing the constraints imposed on it by the substructure. The conversion system of this application can both reduce the impact of changes in the superstructure on the substructure and meet the flexibility requirements of the superstructure.

[0016] Other features and advantages of this application will be described in detail in the following detailed description section. Attached Figure Description

[0023] The technical solution of this application will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] According to one aspect of this application, a conversion system for a TOD (Transit-Oriented Development) roof is provided, wherein the conversion system includes a lower structure 100, a conversion platform 200, and a hinged support 300. The hinged support 300 is aligned with a vertical member 110 of the lower structure 100. The conversion platform 200 is supported on the vertical member 110 by the hinged support 300. The conversion platform 200 includes a conversion beam 210. The conversion beam 210 is provided with a conversion beam support leg 211 corresponding to the hinged support 300 and is connected to the hinged support 300 by the conversion beam support leg 211.

[0025] According to another aspect of this application, a TOD building is provided, wherein the TOD building includes a TOD superstructure conversion system of this application and a superstructure structure 400 disposed above the conversion platform 200.

[0026] In this application, the vertical and horizontal forces of the superstructure 400 are transferred to the vertical members 110 (with each vertical member 110 having a corresponding hinged support 300) via the hinged supports 300, and then to the foundation, while simultaneously releasing bending moments. The superstructure 400 can be flexibly arranged via the transfer platform 200, reducing the constraints imposed by the substructure 100 on the superstructure 400. The transfer system of this application can reduce the impact of changes in the superstructure design on the substructure 100 while meeting the flexibility requirements of the superstructure 400. This application has made appropriate load and bearing capacity provisions for the superstructure 400, and avoids the need for reinforcement and modification work on the substructure 100 due to the addition of new transfer members or seismic isolation supports by using the hinged supports and transfer platform.

[0027] By incorporating a transfer beam support leg 211, the connection stability between the transfer beam support leg 211 and the hinged support 300 can be ensured even if the transfer beam 210 deforms. Specifically, the transfer beam support leg 211 can be welded to the hinged support 300, and the weld will not tear due to deformation of the transfer beam 210.

[0028] In addition, the conversion beam 210 may include reinforcing ribs 212 corresponding to the conversion beam support leg 211. The reinforcing ribs 212 can be pressed against the hinge support 330 to make the force transmission clearer and avoid the weld seam of the conversion beam support leg 211 and the hinge support 300 tearing.

[0029] The hinged support 300 is used to transfer the vertical and horizontal forces of the upper cover structure 400 to the vertical member 110, and does not transfer bending moment to the vertical structure 110. The vertical structure 110 only bears vertical and horizontal forces to meet the support requirements of the structure above it, while reducing the design difficulty of the connection structure.

[0030] The hinged support 300 can take an appropriate form to meet the requirement of transmitting vertical and horizontal forces while substantially not transmitting bending moments. For example, the hinged support 300 may include a spherical support, such as the type specified in GB / T 32836-2016 "Spherical Supports for Steel Structures". Specifically, as... Figure 5 As shown, the spherical support may include an upper support plate 310, a lower support plate 360, and a planar sliding plate 330, a spherical crown plate 340, and a spherical sliding plate 350 disposed between the upper support plate 310 and the lower support plate 360. The upper support plate 310 and the lower support plate 360 ​​are respectively connected to the conversion platform 200 and the vertical member 110.

[0031] The conversion platform 200 can take a suitable form to connect the hinged support 300 and facilitate the installation of the upper cover structure 400. For example, in Figures 1 to 4 In the illustrated embodiment, the conversion platform 200 includes a column-supported conversion layer or a wall-supported conversion layer. Of course, the conversion platform 200 can also take other forms, such as a box-type or truss-type conversion layer. To facilitate the connection of the hinged supports 300, the conversion platform 200 can be provided with corresponding connecting components. Preferably, such as... Figures 2 to 4 As shown, the conversion platform 200 includes a conversion beam 210, which can be provided with conversion beam support legs 211 corresponding to the hinge support 300 and connected to the hinge support 300 through the conversion beam support legs 211. Specifically, the hinge support 300 includes an upper support plate 310, and the conversion beam support legs 211 are fixed to (e.g., welded to) the upper support plate 310.

[0032] Additionally, for ease of installation, the hinged support 300 may include a support base plate 320, to which the lower structure 100 may be fixed. Specifically, as needed, a corresponding connecting structure may be provided in the lower structure 100 to fix the support base plate 320.

[0033] According to one embodiment of this application, such as Figure 2As shown, the lower structure 100 may include a pre-reserved reinforced concrete column head 120, which is fixed to the support base plate 320. To strengthen the connection between the reinforced concrete column head 120 and the support base plate 320, specifically, the conversion system may include a first reinforcing structure 150 surrounding the reinforced concrete column head 120 and connecting the reinforced concrete column head 120 and the support base plate 320. The first reinforcing structure 150 includes a hoop plate 151 surrounding the reinforced concrete column head 120 and connecting it to the support base plate 320, a vertical stiffening rib 152 connecting the hoop plate 151 and the support base plate 320, a circumferential stiffening rib 153 extending radially outward from the hoop plate 151, and a first grouting filler portion 154 filling the space between the hoop plate 151 and the reinforced concrete column head 120.

[0034] The vertical stiffening ribs 152 and circumferential stiffening ribs 153 can be welded to the hoop plate 151. The space between the hoop plate 151 and the reinforced concrete column head 120 can be filled with high-strength grout through pressure grouting to form the first grouting filler part 154, ensuring that the support base plate 320 and the reinforced concrete column head 120 work together to bear the vertical and horizontal forces transmitted from the hinged support 300. The hoop plate 151 has a slightly larger circumferential dimension than the reinforced concrete column head 120. Pressure grouting tightly binds the reinforced concrete column head 120 and the hoop plate 151 together, allowing them to share the load.

[0035] Alternatively, the reinforcing bars 121 of the reinforced concrete column head 120 can be welded to the support base plate 320 through holes at intervals, and the interval reinforcing bars 121 can be T-welded to the support base plate 320. The lower support plate 360 ​​and the support base plate 320 can be welded together.

[0036] According to another embodiment of this application, such as Figure 3 As shown, the lower structure 100 may include a reserved steel column head 130, which is fixed to the support base plate 320. The support base plate 320 has grid-like longitudinal and transverse stiffening ribs 160 at its bottom, and the steel column head 130 is filled with a second grouting filler section 131. Specifically, the support base plate 320 can be welded to the top embedded plate of the steel column head 130. Multiple grouting holes can be provided on the support base plate 320, and the second grouting filler section 131 is formed by pressure grouting with Class II grouting material. The edges of the longitudinal and transverse stiffening ribs 160 are set in a 1:3 slope to ensure that the grouting material fills the steel column head 130 completely. Thus, the concrete bears the pressure transmitted by the hinged support 300, and the longitudinal and transverse stiffening ribs 160 resist the small amount of tensile force transmitted by the hinged support 300. The steel column head 130 itself bears the horizontal force.

[0037] According to another embodiment of this application, such as Figure 4As shown, the lower structure 100 does not have a reserved structure. The lower structure 100 includes a post-anchored shear structure 140. The shear structure 140 includes shear reinforcement 141, shear keys 142, stirrups 143, and a cast-in-place column pier. The shear reinforcement 141 and shear keys 142 are respectively fixed to the support base plate 320. Specifically, the shear reinforcement 141 and shear keys 142 can be welded to the support base plate 320.

[0038] The shear key 142 (e.g., angle steel) transfers horizontal forces to the column pier; its location and quantity can be calculated based on stress requirements. Shear reinforcement 141 extends into the substructure 100 via anchoring, transferring horizontal and vertical forces to the substructure 100. The shear reinforcement 141 can be arranged in rows and columns, and the outer shear reinforcement 141 can be welded to the support base plate 320 through holes to ensure a small amount of tensile force transfer. Because the fixed hinge support 300 can release bending moments, the column pier can ignore most of the bending moment in the design, only bearing shear force and a small amount of additional bending moment. The shear reinforcement 141 should avoid the beam and column reinforcement of the substructure 100, and the anchoring spacing should be 200mm-300mm.

[0039] When the cross-sectional dimensions of the column pier are larger than those of the vertical structure 110, the shear reinforcement 141 can be made of fully threaded rods, and an anchoring steel plate can be installed on the back side of the vertical structure 110 to connect with the fully threaded rods, thereby improving the anchoring effect.

[0040] In this application, the superstructure 400 can be a mature structural system such as a reinforced concrete (steel) frame structure or a frame-shear wall structure.

[0041] According to another aspect of this application, a construction method for a TOD (Transit-Oriented Development) building is provided, wherein the construction method includes: setting up a substructure 100; setting up hinged supports 300 aligned with vertical members 110 of the substructure 100; setting up a transfer platform 200, setting up transfer beam support legs 211 on the transfer beam 210 of the transfer platform 200 corresponding to the hinged supports 300 and connecting the hinged supports 300 through the transfer beam support legs 211; and setting up a superstructure 400 on the transfer platform 200.

[0042] The vertical and horizontal forces of the superstructure 400 are transferred to the aligned vertical members 110 via the hinged supports 300 and then to the foundation, while simultaneously releasing bending moments. The superstructure 400 can be flexibly arranged via the transfer platform 200, reducing the constraints imposed by the substructure 100 on the superstructure 400. The transfer system of this application reduces the impact of changes in the superstructure design on the substructure 100 while meeting the flexibility requirements of the superstructure 400. This application has made appropriate load and bearing capacity provisions for the superstructure 400, and by setting up hinged supports and a transfer platform, avoids the need for reinforcement and modification work on the substructure 100 due to the addition of new transfer members or seismic isolation supports.

[0043] By incorporating a transfer beam support leg 211, the connection stability between the transfer beam support leg 211 and the hinged support 300 can be ensured even if the transfer beam 210 deforms. Specifically, the transfer beam support leg 211 can be welded to the hinged support 300, and the weld will not tear due to deformation of the transfer beam 210.

[0044] In addition, the conversion beam 210 may include reinforcing ribs 212 corresponding to the conversion beam support leg 211. The reinforcing ribs 212 can be pressed against the hinge support 330 to make the force transmission clearer and avoid the weld seam of the conversion beam support leg 211 and the hinge support 300 tearing.

[0045] The lower structure 100 can be equipped with a reserved structure (such as a reinforced concrete column head 120, a steel column head 130, etc.) or a post-anchored connection structure (such as a shear structure 140) to connect the hinged support 300.

[0046] The conversion platform 200 can take a suitable form to connect the hinged support 300 and facilitate the installation of the upper cover structure 400. For example, in Figures 1 to 4 In the illustrated embodiment, the conversion platform 200 includes a column-supported conversion layer or a wall-supported conversion layer. Of course, the conversion platform 200 can also take other forms, such as a box-type or truss-type conversion layer. To facilitate the connection of the hinged supports 300, the conversion platform 200 can be provided with corresponding connecting components. Preferably, such as... Figures 2 to 4 As shown, the conversion platform 200 includes a conversion beam 210, which can be provided with conversion beam support legs 211 at the corresponding hinge support 300 and connected to the hinge support 300 through the conversion beam support legs 211. Specifically, the hinge support 300 includes an upper support plate 310, and the conversion beam support legs 211 are fixed to (e.g., welded to) the upper support plate 310.

Within the scope of the technical concept of this application, various simple modifications can be made to the technical solution of this application, and these simple modifications all fall within the protection scope of this application.
