Parking Deck Structure of Non-Dodging Three-Dimensional Parking Garage

Abstract

A parking deck structure for a non-dodging three-dimensional (3D) parking garage is provided. The parking deck structure includes a parking deck, a parking deck column, a rotary column, and rollers for supporting upward and downward movement of the parking deck along the rotary column. Two wing plates are connected to two opposing sides of the parking deck column. With this arrangement, the parking deck structure is simple in structure and low in cost, and has high bending resistance and a better capability to support the rollers. Furthermore, an end surface connecting plate extending outward is disposed at a lower end of the parking deck column, and the parking deck column is joined to the parking deck by the end surface connecting plate. Accordingly, the parking deck structure is easy to assemble and transport.

Description

CROSS REFERENCE OF RELATED APPLICATIONS[0001]This application is a continuation-in-part of PCT Application No. PCT / CN2009 / 073088 filed Aug. 5, 2009, which claims priority of Chinese application No. 200920129290.4 filed on Jan. 12, 2009, all of which are incorporated herein by reference in their entirety.FIELD OF THE INVENTION[0002]The present disclosure generally relates to a non-dodging three-dimensional (3D) parking garage, and more particularly, to a parking deck structure for a non-dodging 3D parking garage.BACKGROUND[0003]Because of the non-dodging movement and structure, a non-dodging three-dimensional (3D) parking garage can increase the number of parking spaces and make it convenient for vehicle drivers to park their vehicles. For example, a non-dodging 3D parking garage has been disclosed in China Patent No. CN1284915C published on Nov. 15, 2006 and entitled “Non-dodging upper-layer parking deck capable of moving, rotating and lifting”, the entire content of which is hereby...

AI Technical Summary

Benefits of technology

[0008]Embodiments of the disclosure pertain to techniques for increasing bending resistance and improving support for rollers in parking deck structures. More specifically, the parking deck structure has a left and a right L-shaped wing plates that function to support the side rollers and enhance the bending resistance of the parking deck column. The parking deck column can be detachably assembled with the parking deck to make it convenient to transport.

[0015]The present disclosure at least has several benefits. First, the wing plates enhance the bending resistance of the parking deck column and improve support for the rollers. Because the left and the right wing plates are joined to the left side and the right side of the parking deck column, the left side and the right side rollers can be mounted on the wing plates respectively, and the rear elevating support can also be connected to the wing plates. Furthermore, because an elevating chain 30 has an end connected to the parking deck column and the other end connected to a sprocket (not shown) that is fixed to the rotary column, the load acting on the parking deck can be transferred to the rotary column via the elevating chain as well as the front roller, the rear roller and the side rollers. Therefore, the left and the right wing plates have the functions of supporting the side rollers and enhancing the bending resistance of the parking deck column. In one embodiment, the longitudinal beam supporting feet fixed to the longitudinal beam of the parking deck can transfer the bending load from the parking deck to the wing plates and reduce the force acting on the bolts 21. Accordingly, the present disclosure is not only simple in structure and low in cost, but can also improve the capability to support the rollers and the bending resistance of the parking deck column.

[0016]Second, the parking deck column is removably attached to the parking deck. In a particular embodiment, the longitudinal beam formed integrally with the parking deck and the longitudinal beam supporting foot fixed to the longitudinal beam are assembled onto the end surface connecting plate located at a lower end of the parking deck column by bolts, so the parking deck column can be detachably assembled with the parking deck to make it convenient to transport.

Problems solved by technology

Because the parking deck 118 is suspended at a single side and the bending load is borne by the parking deck column 122 alone, the parking deck column 122 is required to have high bending resistance and to provide support for rollers in the conventional parking deck structure; this makes the structure relatively complex and costly.

Furthermore, most of the conventional parking deck columns are welded to the parking deck, which is inconvenient for transportation.
