Double-waterproof composite roof

Abstract

The invention discloses a double-waterproof composite roof which comprises a reinforced concrete face plate, a cement mortar leveling layer, a flexible waterproof layer, a foam concrete layer and an inorganic permeable crystalline waterproof mortar protective layer. The reinforced concrete face plate, the cement mortar leveling layer, the flexible waterproof layer, the foam concrete layer and theinorganic permeable crystalline waterproof mortar protective layer are sequentially flatly laid and overlaid; chemical reaction can be carried out on mortar of the inorganic permeable crystalline waterproof mortar protective layer and free alkali in the foam concrete layer to generate stable permeable crystal substances, the permeable crystal substances can be permeated into concrete crack of theconcrete layer, and particular molecular structures of the permeable crystal substances are [Ca(O-R-OH)2]. The double-waterproof composite roof has the advantages that the waterproof ability and the heat-insulation capability of the building roof can be improved, and the service life of the double-waterproof composite roof can be prolonged.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, in particular to a double waterproof composite roof. Background technique [0002] Hot summer and warm winter area refers to the area where the average temperature of the coldest month in my country is greater than 10°C, the average temperature of the hottest month meets 25-29°C, and the number of days with an average daily temperature ≥ 25°C is 100-200 days. It is one of the five climate zones in my country. One of them mainly includes my country's Fujian Province, Guangdong Province, Guangxi Province, and Hainan Province. The thermal insulation layer of the roof in this area has a great impact on the thermal comfort of the building interior, and it will also affect building energy efficiency. [0003] At present, the practice of building roof thermal insulation layer mainly includes positive roof, and its structure is generally that the thermal insulation layer is below the wate...

AI Technical Summary

Problems solved by technology

These two types of roofs have their own advantages and disadvantages. The thermal insulation material of the vertical roof is under the waterproof layer. Setting several vent holes will increase the cost and affect the appearance of the roof

Thermal insulation materials for inverted roofs generally cannot have a high water absorption rate, otherwise it will affect the thermal insulation effect of the roof. However, if there is a problem with the waterproof layer, maintenance is inconvenient and the cost is high
