Construction method for curved roof of station

Abstract

The invention provides a construction method for a curved roof of a station, and belongs to the technical field of civil engineering. The construction method comprises the following steps of laying a galvanized steel plate on an annular purline, fixing an L-shaped connecting steel plate with the galvanized steel plate and the annular purline together, and fixing the L-shaped connecting steel plate with a longitudinal purline together; installing T-shaped codes on the longitudinal purlines by using a plurality of rows of T-shaped code positioning devices and T-shaped code fixing devices; laying a rock wool heat preservation layer with an aluminum foil damp-proof layer; using a curved surface roof radian measuring device for re-checking the radian formed by a plurality of T codes located on the same annular section on all the longitudinal purlines, and carrying out field profiling on the upright lockrand roof panels according to the actually measured radian and installed in place; and carrying out edge closing and opening closing treatment on the gable wall so that a gap formed below the cornice board rib can be sealed. According to the construction method, the detail construction quality such as roof panel profiling radian and T-shaped codes installation precision is guaranteed, and the construction efficiency and quality of a roof reconstruction project can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a construction method for a station curved roof. Background technique [0002] With the continuous development of science and technology and the continuous improvement of architectural design level, designers tend to design more novel special-shaped buildings. On the premise of satisfying the use function of the building itself, the visual experience of the building can be increased. More visual enjoyment, and then glass curtain walls and decorative aluminum panels with excellent plasticity can be widely used in architectural exterior design. [0003] At present, some station roofs have arc-shaped roofs. The structure of this arc-shaped roof includes hoop purlins, multiple longitudinal purlins fixed on the hoop purlins, and multiple T codes installed on the longitudinal purlins. A T code is connected to the laid curved roof panels to form a curved structural roof. The...

Problems solved by technology

The size of each section of this arc-shaped structure roof is different, the shape arc changes greatly, the installation precision control requirements of the roof panel are high, and the aluminum plate in the middle of the closure and the working surface of the aluminum-magnesium-manganese plate on the end roof span the track area, making construction difficult. Therefore, it poses a severe challenge to the construction of curved roofs on site.
