Rotary-cut plate laminated wood-light weight concrete combined floor system

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.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a rotary-cut glulam-light concrete composite floor (LLC) system. Background technique [0002] Generally, the floors in buildings are mostly composed of ceiling, ordinary concrete floor and surface layer, while in wooden structure buildings, wooden grilles are generally used to form wooden floors. The concrete floor structure has a heavy weight, and its sound insulation and vibration isolation effects are not good; while the pure wood floor has low rigidity and large deformation. At present, the existing wood-concrete composite floors are composed of ordinary concrete and solid wood, but the wood resources in our country are in short supply, and the composite floors using ordinary concrete are still relatively heavy. Contents of the invention [0003] The purpose of the present invention is to provide a rotary-cut laminated wood-lightweight concrete composite floor (LLC) sys...
