Roof heat insulation layer construction process

Abstract

The invention discloses a roof heat insulation layer construction process. Operation is performed on a concrete structure layer laid on a roof. The roof heat insulation layer construction process includes the steps: 1) cleaning a base layer; 2) snapping lines and making slopes; 3) fixing a tube root; 4) laying an air partition layer; 5) laying heat insulation layers including a first heat insulation layer and a second heat insulation layer, filling the space between the first heat insulation layer and the second heat insulation layer, and laying a third heat insulation layer on the second heat insulation layer; 6) trowelling: pounding the upper surface of the third heat insulation layer by a plate vibrator after the heat insulation layers are laid. Slag with the grain size of 8mm, vermiculite with the grain size of 9.5mm and perlite with the grain size of 0.18mm are mixed and compacted according to the mass proportion of 2:1:0.2 to obtain the third heat insulation layer, and the space between the third heat insulation layer and the second heat insulation layer is filled with silicate cement. The process is fine in heat insulation effect and durability, low in manufacturing cost and short in construction cycle.

Description

technical field [0001] The invention introduces a building construction technology, in particular a roof insulation layer construction technology, which belongs to the technical field of building construction. Background technique [0002] With the development of society and economy, no matter from the perspective of the overall international economic climate or the general trend of China's macro economy, the energy problem has become increasingly severe. Building energy consumption has accounted for 27.8% of the total energy consumption in the country. Therefore, energy conservation is imperative. The country Correspondingly, a series of measures and regulations for energy saving and emission reduction have been formulated, and building materials with the concept of energy saving and environmental protection are increasingly receiving key support from the state and favored by the market. Due to the cold winter in the northern part of my country, in order to make the tempe...
