Large-area corrugated roof structure and construction method thereof

Abstract

The invention relates to a large-area corrugated roof structure and a construction method thereof. The roof structure comprises a large-area corrugated roof thin steel sheet, and a first waterproof layer, an insulating layer, an anti-cracking mortar layer, a second waterproof layer, a neat grout layer, a glass fiber reinforced cement panel layer and a surface protection layer are overlapped on the steel sheet in sequence, wherein the insulating layer is formed by a plurality of precast blocks of which the upper layer is in a tooth shape and cast-in-situ layers among the teeth of the precast blocks. The invention also provides a construction method of the roof structure. The invention has the advantages that 1) cast-in-situ cement slurry can still be filled among the teeth of the precast blocks in a condition with a large slope, thus, the thickness can be controlled, and collapse can be prevented; 2) the insulating layer is a cement concrete layer filled with waste polystyrene foams; 3) notches at the bottom of a precast layer are communicated with each other to form a roof layer ventilation passage, and thus the negative effects caused by water leakage and cold bridge can be solved effectively, and high quality can be guaranteed; and 4) by combining industrial production and site operation, the construction period is shortened greatly, and the production cost is reduced.

Description

Technical field: [0001] The invention relates to a roof covering structure, more specifically to a large-area corrugated roof structure and a construction method thereof. Background technique: [0002] In recent years, people's demand for high-end cultural and entertainment exchange places has been increasing day by day, and various large-scale landmark buildings have emerged as the times require. These buildings have unique appearances and extremely varied interior decorations. These unique architectural shapes often use large-span metal arched corrugated roofs, some of which are not only arched longitudinally, but also arched horizontally. New metal roof structure. On the other hand, people pay more and more attention to building energy saving in construction projects. Roof insulation is a very important energy-saving measure. The insulation layer, waterproof layer and roof layer are set on the curved and arched metal thin roof panels. Indispensable in green building. C...

Problems solved by technology

Corresponding to this corrugated roof, the thermal insulation layer in the prior art is divided into the largest unit and prefabricated in advance. First, it is necessary to make a molding mold and set up a prefabricated processing site, so the cost is high and the construction period is long. Secondly, the prefabricated parts need large-scale transfer. Tools, due to their large size, have a high rate of cargo damage during transportation. Thirdly, prefabricated parts need to be stacked when they enter the construction site. The assembly construction is highly technical, poor in safety, and requires a lot of labor. The problem is that water leakage and cold bridges caused by temperature differences will become more and more obvious with the increase of the service life of the building. These are unavoidable problems in construction
