Prestress decoration concrete plank road plate and preparation method thereof

Abstract

The invention discloses a prestress decoration concrete plank road plate. The prestress decoration concrete plank road plate comprises a structure bottom layer and a decoration face layer bonded to the structure bottom layer, two layers of steel bar skeleton nets are laid in the structure bottom layer and the decoration face layer correspondingly and comprise main bars, transverse bars and longitudinal bars, and the two layers of steel bar skeleton nets are fixedly connected through bench bars; the decoration face layer is prepared from the following raw materials in parts by weight: 96-100 parts of cement, 3-5 parts of rubber powder, 1.7-2.0 parts of PP fibers, 3-6 parts of silica fume, 192-216 parts of quartz sand, 2.3-3.2 parts of a water-reducing agent and 26-32 parts of water; and thestructure bottom layer is prepared from the following raw materials in parts by weight: 96-100 parts of cement, 54-61 parts of steam-free powder, 296-318 parts of quartz sand, 354-370 parts of crushed stone, 21-42 parts of water and 2.5-2.8 parts of a water-reducing agent. The prestress decoration concrete plank road plate has the characteristics of very high anti-permeability and anti-bending properties, high strength, high toughness, acid rain resistance and the like. The invention further provides a preparation method of the prestress decoration concrete plank road plate.

Description

technical field [0001] The invention relates to the technical field of concrete prefabricated products, in particular to a prestressed decorative concrete plank slab and a preparation method thereof. Background technique [0002] In environmental governance, such as water area management and tourist attraction development, plank road construction is often required, so special plank road boards need to be produced. At present, the mainstream plank road boards mainly include stone plank road boards and concrete plank road boards, but both have some defects. [0003] Disadvantages of the same type of ordinary precast concrete plank slabs: 1. No concrete decorative surface; 2. Not anti-slip, anti-fouling, anti-freezing and impermeable; 3. No prestressed steel reinforcement, poor crack resistance and low bearing capacity of the slab surface ; 4. The product is simple and unattractive as a whole. [0004] Disadvantages of the same type of stone plank board: 1. The product is not ...
