Open-type dome steel structure

Abstract

The invention relates to an open-type dome steel structure which is characterized by comprising an opening and closing structure opened and closed in a folding manner, a connecting structure and supporting structures, wherein the connecting structure is positioned below the opening and closing structure, and comprises a main beam structure and a building adapter framework; the main beam structure is arranged on the building adapter framework, and provides space supporting for the opening and closing structure; a shape of the building adapter framework is matched with that of a building matrix; the building adapter framework is arranged on the supporting structures; and the supporting structures are connected and fixed with the building matrix. The open-type dome steel structure is simple in construction, clear in stress, flexible in form, wide in application range, economical and applicable.

Description

technical field [0001] The invention relates to an openable and closable dome steel structure used on an open building structure. Background technique [0002] Open building structures, such as gymnasiums, opera houses, etc., and open building structures during construction, such as some power stations with a long construction period, require a dome steel structure that can be opened and closed. This dome structure can be opened in fine weather to provide lighting during use or hoisting space during construction, and can be closed in rainy and snowy weather to protect the facilities in the building. [0003] Existing openable dome steel structures have various forms, and most of the present openable dome steel structures have the following problems: [0004] First, the cost is high and the structure is complicated; [0005] Second, the opening and closing speed is slow, and the response to weather changes is not timely; [0006] Third, as a temporary structure during cons...

AI Technical Summary

Problems solved by technology

[0004] First, the cost is high and the structure is complicated;

[0005] Second, the opening and closing speed is slow, and the response to weather changes is not timely;

[0006] Third, as a temporary structure during construction, it is difficult to provide a flexible and open working surface for hoisting operations;

[0007] Fourth, it cannot be used universally in different building structures
