1. A rotary-cut board laminated wood-lightweight concrete combined floor system is characterized by comprising a rotary-cut board laminated wood grating and a lightweight concrete panel, wherein the rotary-cut board laminated wood grating is a poplar wood;

  • the rotary cutting board glued wood grating consists of a wood panel (3) and a plurality of wood gratings (1) arranged at the bottom of the wood panel, wherein the wood gratings are arranged in parallel and are uniformly distributed at the bottom of the wood panel;

    a layer of moisture-proof paper (4) is laid on the upper surface of the wood panel, GS waterproof materials (5) are coated on the moisture-proof paper, a plurality of shear connectors (6) are uniformly arranged on the edge of the wood panel, then a bidirectional reinforcing mesh (8) is arranged on the GS waterproof materials, and finally a lightweight concrete panel (9) is poured;

    the moisture-proof paper (4) has moisture-proof and air-permeable functions and is laid on the upper surface of the wood panel (3) through wood glue, the GS waterproof material (5) is a two-component waterproof material formed by combining a liquid material and a powder material, the liquid material comprises an acrylic emulsion and an auxiliary agent, the powder material comprises cement, graded sand, fly ash and mineral powder, the fineness modulus of the graded sand is 2.6, the graded area is an area II, the mud content is 0.4%, the mud block content is 0.4%, and the apparent density is 2580kg/m3The bulk density is 1480kg/m3Bulk density porosity 43%;

    the top of the wood grating (1) is provided with a trapezoidal notch (10) with a large upper part and a small lower part, a trapezoidal batten (2) matched with the trapezoidal notch is arranged between the wood panel and the wood grating, and the trapezoidal batten is arranged in the trapezoidal notch;

    the top of the trapezoidal batten (2) is connected with the bottom of the wood panel (3) through PF glue, and the trapezoidal batten is inserted into a trapezoidal notch (10) at the top of the wood grating after PF glue is coated on two inclined planes and the bottom of the trapezoidal batten respectively;

    the lightweight concrete panel (9) is made of ceramsite concrete and consists of cement, water, sand, ceramsite, fly ash, mineral powder and an additive;

    the ceramsite concrete comprises the following components in percentage by mass;

    water;

    sand;

    ceramsite;

    fly ash;

    mineral powder;

    the admixture is 270;

    150;

    704;

    442;

    100;

    31;

    7.62;

    the shear connector (6) is composed of a rectangular base (11) connected with a wood panel and a hollow square upright post (12) arranged above the base;

    the contact part of the rectangular base and the wood panel is provided with a bolt hole, and the shear connector is fixed with the wood panel through a self-tapping bolt (7).
