Precast reinforced concrete with enhanced plasticity

Abstract

The invention relates to the technical field of constructional engineering, in particular to precast reinforced concrete with enhanced plasticity. The precast reinforced concrete comprises a precast slab and a shockproof mechanism, wherein a reinforcing steel bar is arranged in the precast slab, and one side of the reinforcing steel bar is connected to a reinforced steel bar; the reinforcing steelbar and the reinforced steel bar are poured to form an integrated connection; an air hole is arranged in the precast slab, and a fixing block is welded to one end of the precast slab; and a first groove is embedded in the inner side of the other end of the precast slab, and the shockproof mechanism is arranged at the bottom end of the precast slab. Through the arrangement of springs, the crackingof the precast slab on the way due to the uneven road gradient in a process of transporting the precast slab can be prevented, the springs can play a shock reduction role, a situation that a worker directly puts the precast slab on a transportation vehicle and needs to handle with care in the past is improved, the cracking of the precast slab due to collision is avoided, the crack can reduce theanti-seepage ability and the anti-freezing ability while the rust and corrosion of the reinforcing steel bar can be caused, and the later repair and reinforcement work can be very difficult.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a reinforced concrete prefabricated part with enhanced shape. Background technique [0002] The English abbreviation PC (precast concrete) of concrete prefabricated parts is called PC components in the field of housing industrialization. Such as prefabricated reinforced concrete column foundation, prefabricated steel structure steel column foundation, street lamp billboard column reinforced concrete foundation, prefabricated floor slab. Correspondingly, traditional cast-in-place concrete requires on-site molding, on-site pouring and on-site maintenance. Prefabricated concrete is widely used in the fields of construction, transportation, and water conservancy, and plays an important role in the national economy. [0003] Compared with cast-in-place concrete, factory-produced concrete precast has many advantages: [0004] 1. Safety: For construction workers, a r...

AI Technical Summary

Problems solved by technology

[0009] The existing reinforced concrete prefabricated slab is basically the first structure made of steel bars and concrete. However, ordinary reinforced concrete prefabricated slabs have poor crack resistance, and cracks often appear during use, which will reduce the impermeability and The ability to resist frost will also lead to rust and corrosion of steel bars, which will be difficult for later repair and reinforcement work, and will also bring a sense of insecurity to residents
