Single-bar, single-mesh and anti-crack type precast concrete pavement slab convenient to carry, disassemble and assemble and using method of precast concrete pavement slab

Abstract

The invention discloses a single-bar, single-mesh and anti-crack type precast concrete pavement slab convenient to carry, disassemble and assemble. The single-bar, single-mesh and anti-crack type precast concrete pavement slab comprises a slab surface main body, a bottom layer, a surface layer, pre-buried angle steel, pre-buried steel pipes and concrete and is characterized in that the slab surface main body is constructed by pouring concrete; a pipeline is laterally pre-buried in the slab surface main body in the length direction; the surface layer is arranged above the bottom surface; the four sides and edge and corner parts of the slab surface main body are wrapped and covered by the pre-buried angle steel; the outer side face of the pre-buried angle steel is flush with a concrete surface; reservation holes of the four pre-buried steel pipes are uniformly formed in the slab surface main body; a steel bar is inserted into each pre-buried steel pipe.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to a green, environmentally friendly, recyclable, portable and disassembled single-reinforcement, single-network, crack-resistant prefabricated concrete road slab. Background technique [0002] According to the standard "Building Construction Safety Inspection Standard" JGJ59-2011, "Building Construction Site Environmental and Hygienic Standard" JGJ146-2004 stipulates that "main roads on the construction site and the ground of the material processing area should be hardened", the traditional construction site The road is made of C15 or C20 concrete, but the traditional cast-in-place road has obvious disadvantages: 1. After the site or road is poured once, the direction cannot be changed flexibly; 2. The cast-in-place road is a one-time facility and cannot be repeated Recycling; 3. The demolition of the cast-in-place road will cause environmental pollution; the...

After the site or road is poured once, the direction cannot be changed flexibly; 2. The cast-in-place road is a one-time facility and cannot be repeated Recycling; 3. The demolition of the cast-in-place road will cause environmental pollution; the demolished concrete blocks are directly transported to the garbage dump for disposal, and the cost of recycling is high, which greatly increases the environmental pollution of the city
