Circumferential retractable roof structure

Abstract

The invention discloses a ring-direction opening and closing roof structure, which is composed of a multi-spherical four-connected plate mechanism. The spherical four-connected plate mechanism is composed of a first flat plate, a second flat plate, a third flat plate and a fourth flat plate. The first flat plate and the fourth flat plate are conical plates, the second flat plate and the third flat plate are frustum-shaped plates, and the second flat plate is arranged on the conical bottom surface of the first flat plate and passes through the middle column Hinged connection, the third flat plate is arranged on the conical bottom surface of the fourth flat plate and is hinged through another middle column, the second flat plate and the third flat plate are connected by rolling hinges on their common sides, and the fourth flat plate and the first flat plate are hinged. Connected by a common side rolling hinge; the first plate of a spherical four-plate mechanism is connected to the fourth plate rolling hinge of an adjacent spherical four-plate mechanism, and its second plate is connected to the third plate of an adjacent spherical four-plate mechanism Also a rolling hinge connection.

Description

technical field [0001] The invention relates to a retractable roof structure, in particular to a ring-direction retractable roof structure. Background technique [0002] If the development process of mechanism science is regarded as developing from a relatively simple planar mechanism to a more complex spherical mechanism, and then from a spherical mechanism to a more complex space mechanism, then the spherical mechanism is a bridge between the planar mechanism and the space mechanism. bridge. The spherical four-bar mechanism is the most basic and commonly used spherical mechanism. A typical spherical four-bar mechanism is as follows: figure 1 shown. As shown in the figure, axes A, B, C and D are the axes of the four column hinges of the spherical four-bar mechanism, all pointing to the center O. In fact, a real spherical mechanism does not require that each rod be in an arc shape, as long as each rod moves spherically. When the mechanism moves, all points on its compone...

Problems solved by technology

However, the structural form and opening and closing mechanism of hundreds of buildings with retractable roofs that have been built at home and abroad are relatively simple, and the research on retractable roofs lags behind the state of engineering practice
