Construction method of double-layer roof curtain wall structure

Abstract

The invention discloses a construction method of a double-layer roof curtain wall structure. A lower floor system is laid, a plurality of rows of curtain wall supports are arranged on the lower floor system to form a zone, and each curtain wall support comprises a short column, a short column platform and a height-adjustable stand column which are sequentially connected from bottom to top, through measuring and positioning, main keels are fixed at the required height position of the height-adjustable stand columns, the main keels are arranged on the rows of curtain wall supports, the adjacent main keels in the same row are sequentially connected to form a strip-shaped main keel structure, each main keel is supported by two curtain wall supports arranged in a spaced mode, and the connecting positions of the adjacent main keels in the strip-shaped main keel structure are connected to the two ends of the main keels in the adjacent strip-shaped main keel structure through two auxiliary keels, and a triangular grid for arranging the triangular curtain wall plate is formed. The heights of the two ends of the corresponding main keels are changed by changing the heights of the curtain wall supports, so that the angles of the triangular curtain wall plates are changed, and the overall shape of the triangular latticed frame is changed.

Description

technical field [0001] The invention belongs to the field of building structure design and construction, and relates to a construction method for a large-span building structure with a free curved surface roof curtain wall structure. Background technique [0002] In the field of existing public buildings and long-span buildings, there are many architectural design requirements involving free-form roofs. In the traditional design and construction methods, there are mainly several different design ideas and methods: [0003] Concrete roof construction using free-form surfaces: such as the Sydney Opera House, Hochmiloc Restaurant, etc., this type of design and construction method uses a large number of special-shaped concrete formwork, which is not easy to turn around in subsequent projects, and the waste of formwork is large, and even The formwork may not be able to be used more than once, and the shape of the formwork is irregular, making the cost of the formwork itself high...

[0003] Concrete roof construction using free-form surfaces: such as the Sydney Opera House, Hochmiloc Restaurant, etc., this type of design and construction method uses a large number of special-shaped concrete formwork, which is not easy to turn around in subsequent projects, and the waste of formwork is large, and even The formwork may not be able to be used multiple times, and the shape of the formwork is irregular, making the formwork itself costly

[0004] Using the form-finding grid structure can better keep the structure and the curve of the architectural design consistent, but this method is difficult to locate during the construction process, requires a long construction period, requires high-skilled welding workers, relatively harsh construction conditions, and the shape of the building surface It does not necessarily meet the force requirements, and the reticulated shell structure may not meet the requirements of the architectural form
