Modular prefabricated roof panels and method of construction

Abstract

The invention provides a modularization prefabricated roof slab. The modularization prefabricated roof slab comprises prefabricated warm keeping roof slab bodies, a concave composite wood beam, wood beams and wood walls; the two prefabricated warm keeping roof slab bodies are arranged in an angle type; the concave composite wood beam is arranged in the angle-type connecting point; two ends of the two prefabricated warm keeping roof slab bodies are provided with the wood walls correspondently; and a plurality of wood beams are installed between the concave composite wood beam and the wood walls. A building method of the modularization prefabricated roof slab comprises the following steps of installing nailing woods of the two prefabricated warm keeping roof slab bodies in an alignment mode firstly, arranging connecting tenons of the two prefabricated warm keeping roof slab bodies into a ridge mortise of the concave composite wood beam; connecting nailing flange points of the two prefabricated warm keeping roof slab bodies with nails; forming a plurality of level openings in the two prefabricated warm keeping roof slab bodies, and placing the wood beams and the wood walls in the level openings. The modularization prefabricated roof slab and the building method thereof have the advantages that the installation is remarkably simplified; the assembling speed is high; large-component set assembling is adopted; industrialization degree is high; economic effects are good; plenty of site works are reduced; and stress performance is good through a series structure.

Description

technical field [0001] The invention belongs to the technical field of construction, in particular to a modular prefabricated roof panel and a construction method. Background technique [0002] According to statistics, the construction industry consumes about 50% of the earth's energy, 42% of water resources, 50% of materials and 48% of arable land, resulting in ecological imbalance, resulting in 24% of the global air pollution, 50% of the greenhouse effect, 40% of water pollution and 50% of chlorofluorocarbons, etc. [0003] At this stage, my country only pays attention to the use of steel structures and concrete structures in terms of construction, which have poor mechanical properties and complicated processing procedures. In addition, steel, cement, and plastics are non-renewable and unsustainable materials, causing serious problems. Air pollution caused serious impact on my country's environmental pollution control, energy conservation and emission reduction, and adjust...
