Abstract

The invention provides a composite recycled concrete roof panel. The composite recycled concrete roof panel comprises a panel box body, wherein the panel box body is cuboid and comprises a top plate, a bottom plate and a plurality of side plates which are perpendicular to the top plate and the bottom plate and are parallel to one another; a plurality of accommodating cavities are formed in the panel box body; each accommodating cavity is sequentially provided with a mortar layer, a ventilating layer, a foam layer and a reinforcing steel bar layer from top to bottom; each ventilating layer is hollow; a plurality of reinforcing ribs in the same direction are arranged on the bottom in each reinforcing steel bar layer; a reinforcing steel bar net is arranged on each reinforcing rib; a plurality of convex connectors are arranged on each reinforcing rib; the upper part of each convex connector is embedded in the corresponding foam layer; and a waterproof layer is further arranged on the upper surface of the top plate. According to the roof panel, a traditional roof is separately provided with an overhead heat-insulation layer for improvement, the ventilating layers are reserved in the reinforcing steel bar recycled concrete box body, thus, the structure of the roof is simplified, and meanwhile, ventilating and heat-dissipation requirements are met.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a composite recycled concrete roof panel. Background technique [0002] With the development of society and economy, my country's construction industry is in a stage of vigorous development, and the demand for building materials has increased sharply. However, natural sand aggregate resources are limited, resulting in a shortage of natural resources; at the same time, a large number of buildings have been demolished, resulting in a large amount of construction waste, which seriously damages the ecology. environment. Therefore, recycling waste concrete and using it to partially or completely replace natural sand and gravel aggregates to prepare recycled concrete can realize the recycling of construction solid waste and meet the needs of sustainable development. [0003] The current rural roof construction generally adopts the combination of roof brush hydrophobic layer and therma...
