Description
Technical Field
The invention relates to a heat-insulating and waterproof construction method for a roof with ultralow energy consumption, and belongs to the field of heat-insulating and waterproof buildings.
Background
The heat-transfer coefficient of the external wall of the ultra-low energy consumption building is required to be less than or equal to 0.15 W.m-2·K-1The realization of the index puts higher requirements on the heat insulation material and the heat insulation system. And new requirements are also provided for the heat-insulating and waterproof structure of the building roof.
In order to avoid cold and hot bridges caused by drainage nodes in the waterproof structure, in the waterproof design of the ultra-low energy consumption building, the drainage channel of the roof needs to be arranged on the surface insulating layer. The design of the waterproof structure puts forward a brand new requirement, mainly lies in that the water outlet is higher than the basal plane of the roof, and the height difference between the water outlet and the basal plane is not lower than 160mm calculated by the heat conductivity coefficient of the current heat-insulating material according to the requirement of the energy-saving index. Under the premise of such a structure, once water enters a height difference space between the water outlet and the base surface, the heat insulation failure or the water seepage of the base surface of the roof is caused, so that the structure puts unprecedented requirements on the reliability and the durability of the heat insulation waterproof structure of the roof.
The ultra-low energy consumption building is a new technology, for the change of details brought by the new technology, because of lack of feedback of application practice, the prior technical scheme is still used in the current design stage, and because the position of the water outlet is higher than the waterproof surface of the base layer, the first waterproof effect is lost. If the waterproof function can be realized, the heat preservation effect is invalid because the roof heat preservation layer can form a reservoir when the upper layer leaks water; meanwhile, long-term wet soaking of the whole surface can accelerate the aging failure of the waterproof material of the base layer, and finally water leakage is caused. Meanwhile, the upper waterproof layer designed by the scheme is arranged on a soft foundation, and when the waterproof material is applied for a long period, the interface between the heat-insulating layer and the waterproof layer is damaged by debonding caused by expansion with heat and contraction with cold of the heat-insulating material. When the interface is broken, the thinner waterproof material needs to cope with the stress generated by the complicated environmental change alone, and the waterproof material can be fatigue-failed in a shorter period under the environment. When the waterproof material fails, a 'reservoir' without a drainage channel appears below the structure, so that the actual heat insulation performance of the heat insulation material is reduced, and serious water leakage hidden danger or water leakage phenomenon occurs in a building.
