Abstract

The present invention is environment-protecting prefabricated roof for replacing wooden one. The prefabricated roof includes concrete structure with prestressed steel bars and weight reducing holes, and the concrete structure has bottom side setting on bearing walls, inclined top side and two sides adjacent to the bottom side with concave and convex rabbet separately. It is used for the roof of civil building to replace traditional rafter and purlin. It has long service life, high strength, and low cost, and is fireproof, heat insulating, waterproof and suitable for laying tiles and inner decoration.

Description

technical field [0001] The invention relates to a building prefabricated part, in particular to a building roof prefabricated part. Background technique [0002] The roof of a general civil house is composed of columns, beams, ridge purlins, rafters and roof tiles. Except for the roof tiles, the rest are made of wood. This not only consumes wood, does not meet the requirements of environmental protection, but also easily causes fire, requires maintenance within a certain period of time, and has a limited life span. In addition, the existing building prefabricated parts such as floor slabs are all horizontal and regular in shape, which is not suitable for general civil houses. Contents of the invention [0003] The purpose of the present invention is to overcome the disadvantages of the above-mentioned wooden roof, and provide a roof prefabricated part that can replace wooden products with long service life, flame retardant and heat insulation, maintenance-free, high stren...
