Abstract
Description
Technical Field
[0001] This utility model relates to the field of underground parking garage technology, and in particular to a technology for a compact underground multi-level parking garage. Background Technology
[0002] Traditional deep-pit underground multi-level parking garages are often constructed using large-diameter circular, rectangular, or square structures, which require a large area, necessitate the use of large construction machinery, and require sites far from existing structures. In densely populated urban areas and old residential communities where parking spaces are even scarcer, available space is limited, necessitating the construction of parking garages within or adjacent to existing buildings. The limited space makes it difficult to construct these large-sized, multi-level parking garages, and the construction safety risks are also significant. Utility Model Content
[0003] In view of the deficiencies in the existing technology, the technical problem to be solved by this utility model is to provide a compact underground multi-level parking garage with a small footprint, minimal impact on the surrounding environment, and good stability.
[0004] To solve the above-mentioned technical problems, this utility model provides a compact underground multi-level parking garage, including a shaft, in which multiple horizontal parking platforms are arranged at intervals. Each parking platform has a vertically aligned lifting channel in the middle, and a lifting platform for moving transport vehicles vertically is installed within the lifting channel. The feature is that:
[0005] The inner wall of the well shaft is enclosed by a multi-section component wall formed by assembling and casting implanted components. The component wall is an arc-shaped wall, and an inner support wall is laid on the component wall.
[0006] Two sets of parking spaces are symmetrically arranged along the lifting channel on each floor parking platform.
[0007] Furthermore, the inner wall of the well shaft is formed by two arc-shaped walls on the left and right sides, with the two connecting points of the two arc-shaped walls protruding in opposite directions.
[0008] Furthermore, the inner wall of the well shaft is formed by two outwardly protruding arc-shaped walls on the left and right sides, and two outwardly protruding arc-shaped walls at the front and back.
[0009] The compact underground parking garage provided by this utility model adopts two sets of parking spaces arranged horizontally on each parking platform, thus occupying a small area and having little impact on the surrounding area during construction; it adopts an arc-shaped inner wall structure, which, compared with existing circular, rectangular, and square wall structures, concentrates the load-bearing points of the garage at the connection of the arc-shaped wall, resulting in better stability.

[0012] Figure 3 This is a top view of the parking platform of the compact underground multi-level parking garage according to the second embodiment of this utility model. Detailed Implementation
[0013] The embodiments of this utility model are described in further detail below with reference to the accompanying drawings. However, these embodiments are not intended to limit this utility model. Any similar structures or variations thereof that adopt this utility model should be included in the protection scope of this utility model. The commas in this utility model all indicate a relationship between and.
[0014] like Figures 1-2 As shown, the first embodiment of this utility model provides a compact underground three-dimensional parking garage, including a shaft, in which multiple horizontal parking platforms 1 are arranged at intervals. Each parking platform 1 has an upper and lower facing lifting channel 2 in the middle, and a lifting platform 3 for transporting vehicles to move up and down is provided in the lifting channel 2.
[0015] The inner wall of the well is enclosed by a multi-section component wall 4 formed by assembling and casting the implanted components. The component wall 4 is an arc-shaped wall, and an inner support wall 5 is laid on the component wall 4.
[0016] Two sets of parking spaces 6 are symmetrically arranged along the front and back of the lifting channel on each parking platform.
[0017] The inner wall of the well shaft is formed by two arc-shaped walls on the left and right, with the two connecting points of the two arc-shaped walls protruding in opposite directions.
[0018] Because of this parking space structure, the manhole only occupies three car lengths in lateral width, making it suitable for construction in narrow spaces. Furthermore, the connection between the two curved walls provides support for the entire garage, resulting in good stability.
[0019] like Figure 3 As shown, the structure of the second embodiment of this utility model is similar to that of the first embodiment. In the second embodiment, multiple horizontal parking platforms 11 are also arranged at intervals inside the shaft. Each parking platform 11 has a vertically aligned lifting channel 12 in the middle. The lifting channel 12 is also equipped with a lifting platform for the vertical movement of transport vehicles. The inner wall of the shaft is also enclosed by multiple component walls 14 formed by assembling and casting the embedded components. An inner support wall 5 is also laid on the component wall 4. Two sets of parking spaces 16 are symmetrically arranged along the front and back of the lifting channel on each parking platform.
[0020] The second embodiment of this utility model differs from the first embodiment in that the inner wall of the well shaft is formed by two outwardly protruding arc-shaped walls on the left and right sides, and two outwardly protruding arc-shaped walls at the front and rear.
[0021] The connection points of the left and right curved walls and the front and rear curved walls provide support for the entire garage, ensuring good stability.
