Abstract
The invention discloses a rotary-cut plate laminated wood-light weight concrete combined floor system and belongs to the field of building structures. The rotary-cut plate laminated wood-light weight concrete combined floor system comprises a rotary-cut plate laminated wood grating, shear resistant connecting pieces, self-tapping bolts and a light weight concrete face plate based on ceramsite. The rotary-cut plate laminated wood grating is composed of wooden gratings with certain intervals and a wooden face plate, the shear resistant connecting pieces are fixed to the face plate through fastening bolts, a two-way reinforcement mesh is arranged on the face plate, then ceramsite concrete is poured, and an LLC system is formed. Compared with a common pure wood floor system, deformation, vibration and voice transmission of the floor system are reduced effectively; and compared with a traditional reinforced concrete floor, the self-weight of a combined floor is lower, and the earthquake action borne by a structure and the load transmitted to a foundation by the structure are both smaller. The rotary-cut plate laminated wood-light weight concrete combined floor can be used for floorboards, floors, landscape bridges and pedestrian ways.

Infiltration, can guarantee that the two good adhesive property, while rotary-cut plate laminated wood bending resistance and lightweight concrete slab can be given full play to again
Compressive property, formed have good rigidity, intensity it is high, from the good combining structure of heavy and light, fire protecting performance and sound insulation property.
It is of the invention to compare with common pure wooden superstructure, can effectively reduce deformation, vibration and the acoustic of superstructure；With traditional steel
Bar concrete floor is compared, and the deadweight of composite floor is lower, structure is born in earthquake geological process and be delivered to basic lotus
Carry all less.The present invention rotary-cut plate laminated wood-lightweight concrete composition floor can be used for floor, floor, landscape bridge and
Pavement.
The present invention meets the development strategy of national energy-saving reduction of discharging and building industrialization, compared with pure wooden superstructure, can effectively subtract
Few superstructure deforms, vibrates and transaudient.Compared with concrete floor system, dead load mitigates, high capacity, while sound insulation, vibration isolation, easily
In construction.China's timber resources dress in short supply, and rotary-cut plate laminated wood is the construction material being processed into using China fast-growing forest, tool
Have saving natural resources, it is cost-effective the characteristics of, considerable economic benefit can be brought.The present invention have lightweight, high-strength, sound insulation,
The functions such as vibration isolation, protection against the tide, can substitute the concrete floor and wooden flooring in building, ecological, environmental protective, using comfortable, it is easy to apply
Work.
