Treatment process for cold bridges of prefabricated building

Abstract

The invention especially relates to a treatment process for cold bridges of a prefabricated building, belonging to the field of buildings. The treatment process comprises the following steps: pouring a layer of concrete in a wallboard die on a production line in a workshop; then laying a polystyrene board heat-insulation layer on the concrete; then pouring another layer of concrete on the heat-insulation layer, wherein the thickness of the two layers of concrete is identical; and when the concrete at two sides is cured, uniformly brushing two sides of the wallboard of the heat-insulation layer with a layer of heat-insulation coating. The treatment process is simple in design, convenient to construct and short in construction cycle, overcomes the phenomenon of cold bridges in construction of prefabricated buildings, reduces the amount and area of cold bridges, guarantees comfortableness of indoor temperature, lowers heating load and energy consumption of prefabricated buildings, and is applicable to large-scale production.

Description

technical field [0001] The invention relates to the field of construction, in particular to a cold bridge treatment technology for prefabricated houses. Background technique [0002] At present, housing construction has gradually abandoned traditional construction methods, and more and more prefabricated houses are used. In prefabricated residential buildings, cold bridge phenomenon often occurs. The cold bridge phenomenon refers to the fact that when the heat conducts between the building envelope and the outside world, because the heat transfer coefficient of some parts of the envelope structure is significantly greater than that of other parts, the heat is concentrated and rapidly transferred from these parts, which affects the prefabricated residence. The thermal insulation performance of the thermal insulation material in the wall panels increases the heating load and energy consumption of the building.
