The invention provides a lightweight aggregate concrete-bamboo integrated material composite floor system, which comprises concrete (1), an upper wing edge (2), a lower wing edge (3), a side web plate(4), a middle web plate (5), steel bars (6), nails (7), screws (8), shear connectors (9), a floorboard (10), a ceiling board (11) and a gypsum board (12). The lightweight aggregate concrete-bamboo integrated material composite floor system is characterized in that the concrete (1) is positioned on the top of the composite floor system and is used for bearing the pressure; the side web plate (4) and the middle web plate (5) are positioned in the middle part of the upper wing edge (2) and the lower wing edge (3), and is used for bearing the shear stress; the steel bars (6) are positioned in thelower wing edge (3) and is used for bearing the pulling stress; the floorboard (10) is positioned between the concrete (1) an the upper wing edge (2), is connected through the shear connectors (9), and achieves the function of a formwork; the ceiling board (11) and the gypsum board (12) are positioned at the bottom of the floor system, and achieves a fireproof function. The lightweight aggregateconcrete-bamboo integrated material composite floor system belongs to a novel floor system with the advantages of simple structure, low manufacturing price and good stress performance.
Description
technical field [0001] The invention relates to a light aggregate concrete-bamboo laminated material composite floor, in particular to a composite floor member of bamboo and other materials, belonging to the field of civil engineering structures. Background technique [0002] In order to reduce the dependence on high-energy-consuming and high-polluting building materials such as clay, steel and cement, energy-saving, environmentally friendly and renewable green building materials are increasingly favored by people. my country has extremely rich bamboo resources. Bamboo has the advantages of high strength, fast growth, easy processing and good toughness. It can replace ordinary broad-leaved wood and coniferous wood and is a renewable raw material with wide application prospects. The use of bamboo as the main building material in the field of engineering benefits the country and the people. "Replacing wood with bamboo" will help reduce the dependence on traditional building ma...
