Folding switching house cover

Abstract

The invention discloses a retractable fold steel roof structure, comprising H-shaped steel beams, horizontal intersecting supports between beams, fixed nodes on ends of the beams, driving wheels, rolling nodes on the ends of the beams, drive sets, retracted stopping steel plates, a connecting rod, slide rails on end parts of the H-shaped steel beams, slide rails on middle parts of the H-shaped steel beams, rotating rods, steel balls, components for welding H-shaped steel plates, pin shafts, roof supporting components, guide rails and rails for the beams to run. The invention is characterized in that: the retracted stopping steel plates on the rails lock or release a roof; the drive sets drive a beam which is connected with the drive sets to run through the connecting rod, so that a horizontal intersecting support between beams is driven to slide in slide rails, thereby other beams are driven to run along rails at two sides; the retractable folding and unfolding of the horizontal intersecting supports between beams realize the folding and unfolding of the whole roof. The retractable fold steel roof structure has the advantages of reasonable structure, definite force-transfering mechanism, simple design and construction and low cost, and is especially suitable for medium-and-small-sized buildings.

Description

technical field [0001] The invention relates to a roof, in particular to a retractable roof. Background technique [0002] The opening and closing of the roof is a new requirement for building functions in recent years. At present, in the opened and closed roofs that have been built, the sliding opening and closing form of the spatially rigid grid roof unit is the main form; in addition, the concept of folding and closing is also applied in the opening and closing structure. The folding opening and closing of the cover structure, the folding grid frame and the folding grid shell are mainly used. The above-mentioned opening and closing structures are described in "Research on Opening and Closing Roof Structures" (Author: Zhang Fengwen, Doctoral Dissertation of Tianjin University, 2001) and "Modern Space Structure" (Author: Liu Xiliang, Tianjin: Tianjin University Press, 2003.) There are more detailed introductions. Their design and construction are very complicated and the ...

Problems solved by technology

[0003] In order to overcome the defects of the complexity and high cost of the existing retractable roof structure technology, the present invention provides a steel beam type folding and It also has the characteristics of reasonable structure, simple design and construction, and low cost. It can well meet the requirements of some small stadiums and other small and medium-sized buildings for the roof opening and closing function.
