Description

A roof panel and a roof

technical field

The utility model belongs to the field of building structures, in particular to a roof panel and a roof cover.

Background technique

The traditional roof structure is to erect the roof truss on the wall panels or beams, and then lay tiles on the roof truss. With the rise of modern buildings, the structure of the roof has become diversified. The roof integrates heat insulation and waterproof functions. It is usually divided into cast-in-place and There are two ways of laying roof panels. For cast-in-place roofs, especially sloped roofs, it is difficult to support the formwork, the molds have many shapes, the process is complicated, and the weight of the roof is relatively large, which is not conducive to earthquake resistance. In the roof panel laying structure, there is mainly a steel roof truss on the wall panel, and then the roof panel is placed on it, and the roof panel is composed of "profiled steel plate + insulation board + profiled steel plate". For example, the patent CN204715639U discloses a profiled steel Slab roof panel, including profiled steel plate, longitudinal steel bars, lightweight aggregate concrete layer, membrane waterproof layer and protective layer, the profiled steel plate is located at the bottom of the roof panel, longitudinal steel bars are arranged in the groove of the profiled steel plate, poured on the profiled steel plate There is a light aggregate concrete layer, and the light aggregate concrete layer integrates the profiled steel plate and the longitudinal steel bar into one. However, the rigidity of this kind of roof panel is relatively poor, so the size of the production is small, and the span of the roof panel is small. Complicated, resulting in long construction period.

To sum up, in order to save costs and improve construction efficiency, it is urgent to provide a new type of roof panel and a roof including the roof panel.
