A three-dimensional garage shaft structure

Abstract

The invention relates to a vertical shaft cylinder structure for a stereo garage. The vertical shaft cylinder structure comprises a cylinder, 12 piles and more than one layer of support floor slab, wherein the cylinder is cast by concrete; the piles are evenly distributed on the cylinder wall of the cylinder; the support floor slab is vertically distributed along the axial direction of the cylinder; the inner cylinder wall of the cylinder is formed by 12 arch walls; a cylinder expansion part is formed at the connected part of two adjacent arch walls; the 12 piles are coated with the 12 cylinder expansion parts respectively; the support floor slab and the cylinder wall of the cylinder are integrally molded; and the support floor slab is in an annular form as a whole. The inner wall of the cylinder is arranged into an arch form, so that effective wrapping on the piles is ensured; meanwhile, the wall thickness at the top point of each arch wall is reduced; the used materials are reduced; the structure of each arch wall is relatively stable; the vertical shaft cylinder structure has relatively good bearing capacity on pressure and shearing force transmitted by earthwork at the outer side. The support floor slab is brought out when the cylinder is cast; construction of a late parking floor slab is greatly facilitated; and meanwhile, the vertical shaft cylinder structure is relative stable as a support base of the parking floor slab.

Description

technical field [0001] The invention relates to the technical field of fixed buildings, in particular to a shaft structure of an underground three-dimensional garage. Background technique [0002] At present, with the intensification of the urbanization process, the permanent population of the city is increasing, and the available land area in the city is getting less and less. With the development of the country, there are more and more household vehicles, so parking has become an important problem that plagues people's normal life and work in the city. [0003] In order to alleviate the lack of parking spaces in the current cities and overcome the disadvantages of existing underground garages, underground three-dimensional garages have been specially designed, such as a barrel-type three-dimensional garage disclosed in Chinese invention patent application No. 201410596065.7, which has a small footprint, The post-construction takes up less space on the ground and has the a...

AI Technical Summary

Problems solved by technology

[0004] The barrel-type three-dimensional garage includes a concrete-cast garage shaft, surrounded by a barrel, and the construction process of the barrel is cumbersome during the pouring process, especially when the inner diameter is relatively small and the depth is relatively deep, the construction difficulty increases In addition, due to the limitation of construction technology and safety standards, its cost is relatively high. In addition, when pouring the cylinder first, and then pouring the parking floor slab layer by layer, the construction process also has certain difficulties
