Preferably, the connecting piece is a limiting bolt, and the outer covering surface is a fiber reinforced covering surface.

As optimization, the fiber yarns for producing the fiber reinforced covering adopt medium-alkali glass yarns.

Preferably, the lattice plate comprises a horizontal support plate, a vertical support plate and a transverse support plate, two ends of the horizontal support plate are fixedly connected with the vertical panel and the bottom panel respectively, two ends of the vertical support plate are fixedly connected with the plane panel and the bottom panel respectively, and two ends of the transverse support plate are fixedly connected with the inner sides of the two side panels respectively.

The beneficial effect of this scheme is: a fiber reinforced cladding wood-based fabricated stair is characterized in that a stair body is not made of steel bars, cement, sand and stones, so that the stair is environment-friendly and energy-saving; because the framework is formed by adopting the wood-based material, the self weight of the framework is greatly reduced; the prefabricated, transportation and hoisting of the assembly type building engineering are greatly facilitated, the construction speed is high, and the period is short; the outer surface is coated with the fiber reinforced covering, is supported by medium-alkali glass fibers, has the performances of fire prevention, water prevention, freezing prevention, acid resistance, tensile resistance and the like, and can meet the use requirements of the wooden stair main body in daily life;

the lattice plates are arranged to support the interior of the stair main body, so that the stress of the stair can be balanced, and the stability of the stair is improved;

through set up spacing bolt between stair main part and stair ladder roof beam, can restrict the removal of stair, nevertheless unfixed, can prevent effectively that the stair main part from bearing great shear force, reduces daily use to the damage of stair main part, prolongs the life of stair main part.
