Problems solved by technology

However, the crack resistance of ordinary reinforced concrete prefabricated parts is poor, and cracks often appear during normal use, which is very unfavorable to hydraulic reinforced concrete prefabricated parts. The existence of cracks will reduce the impermeability and frost resistance, and lead to corrosion of steel bars, affecting the durability of structures. The work of repairing and strengthening is also relatively difficult. For some hydraulic structures, cracks will cause water leakage, which will affect the normal use of structural parts and bring unsafe

Embodiment Construction

[0008] The present invention will be further described below.

[0009] The reinforced concrete prefabricated part described in the production process of the present invention, in the preferred embodiment of the present invention, is a prefabricated reinforced concrete structure prefabricated part of a hydraulic building, and the stress in the middle of the beam is relatively complicated and the environment is relatively harsh. In the case of a surplus safety factor, cracks will still appear, bringing unsafe factors, and on-site repairs are also extremely inconvenient. Therefore, in the prefabrication process of beams, when the concrete is about to solidify, for the areas prone to cracks, the cut out Carbon fiber cloth impregnated with epoxy-based adhesive resin is rolled on the surface of the concrete protective layer. The carbon fiber cloth used in this embodiment has a design tensile strength of 420g / cm2, a thickness of 0.11mm, and a weight of 200g / m2. After the adhesive resi...

Abstract

The invention discloses a reinforced concrete prefabricated part with reinforced plasticity. The reinforced concrete prefabricated part is provided with a plurality of steel bars and a concrete protective layer with sufficient thickness and at the exteriors of the steel bars. The reinforced concrete prefabricated part is characterized in that the reinforced concrete prefabricated part further comprises a carbon fiber reinforced plasticity part consisting of carbon fiber cloth and epoxy bonded resin. The reinforced concrete prefabricated part is characterized in that the carbon fiber reinforcedplasticity part consisting of the carbon fiber cloth and the epoxy bonded resin is placed in the concrete protective layer, the carbon fiber cloth is fixed on the steel bars, and the reinforced concrete prefabricated part with the carbon-containing reinforced plasticity aims to solve deficiencies in the prior art, has the high crack resistance, and meets urgent requirements of use safety for a hydraulic structure in society.

Description

technical field [0001] The invention relates to a reinforced concrete prefabricated part with enhanced plasticity, which belongs to the field of prefabricated component production. Background technique [0002] In the prior art, the reinforced concrete prefabricated part is a structural part which is composed of two materials, steel bar and concrete, which are jointly stressed. It uses concrete to bear the pressure and steel bars to bear the tensile force, so reinforced concrete prefabricated parts can make full use of the mechanical properties of steel bars and concrete. However, the crack resistance of ordinary reinforced concrete prefabricated parts is poor, and cracks often appear during normal use, which is very unfavorable to hydraulic reinforced concrete prefabricated parts. The existence of cracks will reduce the impermeability and frost resistance, and lead to corrosion of steel bars, affecting the durability of structures. The work of repair and reinforcement is a...
