Energy-saving ventilation roof structure and construction method thereof

Abstract

The invention provides an energy-saving ventilation roof structure which comprises a herringbone roof, wherein a rectangular concrete body arranged in the longitudinal direction is arranged in the middle of the herringbone roof; a plurality of cable guide pipes arranged at equal intervals and in the transverse direction are arranged in the longitudinal direction of the rectangular concrete body; each cable guide pipe is of a reverse V-shaped structure; a circular arc transition section is arranged in the middle part of the reverse V-shaped structure; verge boards are arranged at the two ends of the herringbone roof; inclined holes arranged in a way of corresponding to the cable guide pipes are formed in the verge boards; the verge board sections positioned among the cable guide pipes are provided with eave grates; ventilation structures are arranged in the rectangular concrete body; a hanging cable device is arranged in each cable guide pipe, and comprises a steel strand; the two endsof the steel strands are anchored onto anchoring boards arranged at the outer sides of the verge boards at two sides; and flashing boards are arranged at the outer sides of the anchoring boards of thecable hanging devices. The cost is reduced by optimizing the roof structure; the waterproof function is ensured; meanwhile, the energy can be saved, and ventilation can be realized; the performance of a roof system is improved; and the service life of the roof system is prolonged.

Description

technical field [0001] The invention belongs to the technical field of building construction, in particular to an energy-saving ventilated roof structure and a construction method thereof. Background technique [0002] At present, people have been paying attention to the thermal insulation of building roofs, especially those residents who live on the top floors, who will be troubled by the heat in summer. Many, after leveling the cement sand on the slope concrete, spread the waterproof coiled material, add polystyrene insulation board and lay a 40mm fine stone concrete protective layer, and then carry out the tile construction after the wooden water strips and wooden hanging tile strips . Especially when pouring the leveling layer on the concrete roof structure, it is necessary to check the flatness of the leveling layer through the 2m gauge and the plug gap of the feeler gauge, and the error is required to be less than 5mm. No more than 4mm. When the leveling layer is pou...

AI Technical Summary

Problems solved by technology

Especially when pouring the leveling layer on the concrete roof structure, it is necessary to check the flatness of the leveling layer through the 2m gauge and the plug gap of the feeler gauge, and the error is required to be less than 5mm. No more than 4mm. When the leveling layer is poured, the roof accessories and embedded parts are pre-positioned and installed, and then the sundries on the leveling layer are cleaned up. There is construction trouble, and the construction period is long, which increases the construction period cost and labor cost.
