Paving method of warm-keeping and water proofing pearlite integrated floor heating system

Abstract

The invention discloses a paving method of a warm-keeping and water proofing pearlite integrated floor heating system which is installed on the ground. The method comprises following steps: 1) multiple floor mounting keels are fixed on the ground with intervals; 2) inorganic lightweight materials of foamed perlite and polyurethane foaming material are synchronously and uniformly sprayed between adjacent floor mounting keels; the polyurethane foaming material is synchronously sprayed where the inorganic lightweight materials of foamed perlite is sprayed and performs foaming and attaching to the surface of the inorganic lightweight materials of foamed perlite to form a heat insulation layer; 3) before the heat insulation layer is solidified and set, floor heating material is embedded in the heat insulation layer, or, after the heat insulation layer is solidified and set, the floor heating material is paved on the heat insulation layer surface; 4) after the heat insulation layer is solidified and set and the installation of the floor heating material is completed, floors are paved on the heat insulation layer or on the floor heating material. The invention relates to the field of buildings and discloses a paving method. The heat insulation layer is seamless and integrated, thereby substantially improved the heat insulation performance of floor heating.

Description

technical field [0001] The invention relates to the field of construction, in particular to a pavement method for a perlite warm-keeping and waterproof integrated floor heating system. Background technique [0002] At present, my country's building energy consumption accounts for about 1 / 3 of the total energy consumption of the whole society. The living area of ​​heating cities in northern my country only accounts for 10% of the national urban living area, but building energy consumption accounts for 40%. The largest energy consumption of buildings in our country is heating and cooling. Compared with developed countries with similar climate conditions, the heating energy consumption per square meter of buildings in our country is about three times that of developed countries. my country is currently making every effort to promote building energy saving by 65%. standard. [0003] Therefore, the thermal insulation performance of the original building is extremely poor, and the...

Problems solved by technology

[0003] Therefore, the thermal insulation performance of the original building is extremely poor, and the energy consumption is too large. It is necessary to carry out thermal insulation and energy-saving renovation. One of the simple and effective means is to improve the thermal insulation performance

Among them, the foamed cement casting method has low thermal insulation performance, poor effect, heavy self-weight, and increases the construction load; among the inorganic thermal insulation materials, one type is rock wool block or rock wool felt, which is easy to absorb moisture and fall off and accumulate after long-term use, and the other type is foam Inorganic insulation materials such as perlite, foamed ceramics, and foamed glass are assembled in multiple pieces, and there are seams that greatly reduce the heat resistance effect, and are easy to absorb water

The application of low-cost organic insulation materials such as expanded polystyrene, expanded polyurethane and expanded phenolic formaldehyde in building insulation is greatly limited, mainly due to low flame retardancy and fire resistance
