Problems solved by technology

[0005] However, this structural conversion method cannot reduce the seismic effect of the superstructure, nor can it reduce the impact of vehicle vibration in the lower depot on the superstructure
[0006] Therefore, there is an urgent need for a conversion structure suitable for TOD projects, which can solve the problem of the seismic effect of the upper structure of the upper cover plate and the impact of vehicle driving vibration on the upper structure

Embodiment 1

[0057] like figure 2 As shown, a TOD upper cover shock-isolation transfer structure includes an upper transfer layer 300, a lower transfer layer 400, and several shock-isolation buffer supports 500, and several shock-isolation buffer supports 500 are arranged on the upper transfer layer 300 and the lower transfer layer Between 400.

[0058] The upper conversion layer 300 is arranged at the lower part of the superstructure 100, and the upper surface of the upper conversion layer 300 is connected with several first support structures 101 of the superstructure 100. The first support structures 101 can be support columns or shear walls.

[0059] Wherein, the superstructure 100 may be buildings such as residences, shopping malls, and hotels.

[0060] The first distance between the upper surface of the upper conversion level 300 and the lowermost floor 102 of the superstructure 100 is at least 0.5 m.

[0061]The lower conversion layer 400 is disposed on the upper part of the lowe...

Embodiment 2

[0097] In a certain TOD project in Shanghai, the conversion structure adopted in the initial design is a hard conversion structure (refer to figure 1), that is, the down conversion layer 400 is directly connected to the superstructure 100 and the substructure 200 respectively, and the thickness of the down conversion layer 400 is at least 2500 mm. Due to the irregular structure of the substructure 200 , the lower conversion layer 400 below part of the wall of the superstructure 100 cannot meet the force requirements, and structural reinforcement is required before implementation. Since the substructure 200 of the TOD project is a subway depot, and the operation of the subway cannot be stopped, reinforcement construction cannot be performed on the substructure 200 . In addition, due to the hard transfer structure, there is no seismic isolation effect, so that the seismic force of the superstructure 100 will not be reduced. In addition, there is a huge difference between the fl...

Abstract

The invention relates to a TOD upper cover plate isolation conversion structure which comprises an upper conversion layer, a lower conversion layer and an isolation cushioning support, wherein the upper conversion layer is connected with a plurality of first supporting structures of a superstructure, the lower conversion layer is connected with a plurality of second supporting structures of a substructure, and the isolation cushioning support is arranged between the upper conversion layer and the lower conversion layer; in the vertical direction, the first projection range of the upper conversion layer is positioned in the second projection range of the lower conversion layer, or the first projection range overlaps with the second projection range. The TOD upper cover plate isolation conversion structure has the advantages that the double conversion layers are respectively connected with the superstructure and the substructure, so that the superstructure and the substructure are separated and converted, and thus the development of the superstructure and the development of the substructure do not affect each other; the isolation cushioning support is arranged between the upper conversion layer and the lower conversion layer, so that the seismic force of the superstructure is reduced, and the impact of vibration caused by vehicle running on the superstructure is reduced; and by the reasonable arrangement of the isolation support, the limit of depth-width ratio of the superstructure is increased, and the actual used area is increased.

Description

technical field [0001] The invention relates to the technical field of TOD, in particular to a shock-isolation conversion structure of a TOD upper cover plate. Background technique [0002] In TOD (transit-oriented development, TOD, public transport-oriented development) projects, the space above the subway is usually used as the planning and construction base, that is, the space on the subway upper cover. Compared with traditional projects that use the ground as the base, the TOD project uses the roof of the subway building as the base for construction. [0003] In the TOD project, the primary structural problem encountered is that the column grid of the upper structure of the roof slab cannot correspond to the column grid of the lower structure of the roof slab. It is necessary to use the conversion layer for structural conversion to meet the development needs. [0004] Conventional structural transformation methods include Liang’s transformation, plate transformation, bo...
