Large-span prefabricated multi-rib sandwich panel and corrugated tile combined roofing

Abstract

The invention discloses a large-span prefabricated multi-rib sandwich panel and corrugated tile combined roofing. The roofing comprises a panel body and corrugated tiles, wherein the corrugated tilescover the panel body; the longitudinal section of the top surface of the panel body is in a pyramid shape; the panel body comprises a bottom plate, longitudinal ribbed beams, transverse ribbed beams and sandwich blocks; each longitudinal ribbed beam comprises L-shaped ribbed beams positioned on two sides of the bottom plate and a T-shaped ribbed beam positioned in the middle of the bottom plate; the longitudinal ribbed beams are perpendicular to the transverse ribbed beams; the sandwich blocks are positioned in cavities formed by the bottom plate, the longitudinal ribbed beams and the transverse ribbed beams; vertical reserved holes penetrating through the panel body are formed in the longitudinal ribbed beams and used for connecting front and rear wall boards; transverse through holes areformed in the transverse ribbed beams and used for connecting and hoisting panel bodies. The large-span prefabricated multi-rib sandwich panel and corrugated tile combined roofing is large in span and good in bearing property, has the advantages of low weight, high corrosion resistance, heat preservation and insulation, low manufacturing cost and the like, and has a wide market prospect.

Description

technical field [0001] The invention relates to the technical field of building roof panels, in particular to a composite roof of large-span prefabricated dense rib sandwich panels and corrugated tiles. Background technique [0002] Due to the characteristics of light weight, thermal insulation and low price, color steel sandwich panels have been widely used in long-span light steel structures. Large-scale pig farms, etc.), due to the poor anti-corrosion ability of the profiled steel plate used in the color steel sandwich panel, in actual engineering applications, in order to solve the problem of poor anti-corrosion ability of the color steel sandwich panel, the usual practice is to single Surface sandwich color steel plate is combined with PVC board ceiling. Although this method solves the anti-corrosion problem of color steel sandwich panel, it does increase the construction process and cost. Therefore, it is urgent to develop a novel composite roof panel that is light in...
