A method for reinforced concrete work construction in cold winter

Abstract

The invention provides a method for reinforced concrete work construction in cold winter. The method comprises the steps of erecting a steel skeleton at a construction site, selecting a plurality of steel bars as heat conductive steel bars, tying heating wires on the heat conductive steel bars, connecting all the heating wires to a power source, pouring concrete to enable the steel skeleton to beembedded in the concrete and obtaining a construction body after the concrete solidifies. According to the technical scheme of the present invention, by tying the heating wires on the plurality of steel bars, when the concrete is poured, the heating wires heat the interior of the concrete, so that the temperature inside the concrete is always maintained within a temperature range suitable for thehydration reaction, thus ensuring that the concrete can be solidified smoothly under cold conditions; and the strength of the concrete structure during solidification continues to grow. According to the invention, heat preservation measures are taken for the concrete by setting up a heat insulation shed, so that the concrete hydration reaction can be carried out more fully and completely, and a foundation is laid for improving the construction quality of the building body.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for reinforced concrete engineering in cold winter. Background technique [0002] In various construction projects, the reinforced concrete construction technology is mature, the construction is convenient, and the structural strength, bearing capacity, stability and reliability of various buildings obtained have outstanding advantages, so it is widely used in various construction projects. Application, in various reinforced concrete projects, the principle of hydration reaction of concrete is mainly applied, however, the hydration reaction of concrete is greatly affected by the ambient temperature of the construction site, research shows that when the ambient temperature is 0°C to 4°C, The setting time of concrete is three times longer than that at an ambient temperature of 15°C, and when the ambient temperature drops to -3°C to -5°C, most ...

[0002] In various construction projects, the reinforced concrete construction technology is mature, the construction is convenient, and the structural strength, bearing capacity, stability and reliability of various buildings obtained have outstanding advantages, so it is widely used in various construction projects. Application, in various reinforced concrete projects, the principle of hydration reaction of concrete is mainly applied, however, the hydration reaction of concrete is greatly affected by the ambient temperature of the construction site, research shows that when the ambient temperature is 0°C to 4°C, The setting time of concrete is three times longer than that at an ambient temperature of 15°C, and when the ambient temperature drops to -3°C to -5°C, most of the water condenses into solid ice, so the hydration reaction partially stops. When the temperature reaches -10°C, due to the absence of liquid water, the hydration reaction stops completely, and the concrete cannot be effectively solidified, which has a great impact on the construction quality of the building and the construction progress of the project.
