Energy-saving materials with small heat conductivity coefficient, low volume weight and low water absorption coefficient, such as perlite, pumice, furnace slag and the like which are poured in site by adding cement into bulk materials, are arranged between the structural layer 10 and the heat-insulating waterproof layer; the plate is made of polystyrene, cement or asphalt perlite, aerated concrete and cement vermiculite.
Example 6
This embodiment provides a novel energy-conserving building waterproof insulation roof structure, and it is basically the same as any one of embodiments 1-5, and the main difference between the two lies in: the second waterproof and insulating layer 50 is made of polyurethane heat-insulating and waterproof material.
The polyurethane hard foam material has various performances of durability, waterproofness, heat preservation, heat insulation, environmental protection and the like, has good adhesive performance, can be firmly adhered with metal, concrete materials and the like in a specific construction process, enables a hard foam layer and a roof base layer to be integrated, and is not easy to delaminate. In areas with large temperature difference, high temperature in summer and low temperature in winter, such as most areas in the north of China, the polyurethane hard foam material can be guaranteed not to be brittle at minus 50 ℃ and not to melt at high temperature of 150 ℃. In addition, the polyurethane hard foam material has stronger resistance to general acid-base substances, and can effectively ensure that the building roof is not corroded in areas with serious environmental pollution and frequent acid rain.
Example 7
This embodiment provides a novel energy-conserving building waterproof insulation roof structure, and it is basically the same as any one of embodiments 1-6, and the main difference between the two lies in: the insulation layer 60 is laid from extruded foam board. The extruded sheet is widely applied to dry wall body heat preservation, flat concrete roof and steel structure roof heat preservation, damp-proof heat preservation in the fields of low-temperature storage ground, low-temperature floor radiant heating pipe, parking platform, airport runway, expressway and the like, controls ground frost heaving, and is a heat-insulating and damp-proof material with excellent quality and low price in the current building industry.
In summary, the embodiment of the present invention provides a novel energy-saving building waterproof heat preservation roof structure, which has at least the following advantages or beneficial effects:
the invention lays a multilayer waterproof heat-insulating structure without increasing the thickness of the roof and adding additional construction equipment, the roof structure is simple, the construction is rapid, the energy consumption in the construction process is effectively reduced, the heat-insulating and waterproof performance of the roof is effectively improved, the damage and erosion to the internal structure of the building caused by rainwater leakage are reduced, the dissipation of indoor heat radiation and the entrance of outdoor heat radiation are greatly prevented, the maintenance cost and the use of an air conditioner are reduced, and the living comfort of residents is improved.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
