Construction method, system and special components of a ventilating roof system

Abstract

The invention discloses a construction method of a permeable roof system. The construction method comprises the following steps of: (1) arranging a waterproof layer on a beam slab of a roof concrete structure and an upstream face which is built at the corner position of a rooftop wall; and (2) arranging a moisture absorption and desorption dewatering packing layer on the waterproof layer, wherein the moisture absorption and desorption dewatering packing layer is made of a breathable water-absorbing material and has the functions of moisture absorption and desorption and dewatering. The invention also provides the permeable roof system which comprises the waterproof layer and the moisture absorption and desorption dewatering packing layer. The invention also provides a foam heat retaining panel and a dewatering panel which are used for the permeable roof system. The permeable roof system is capable of meeting the heat preservation energy saving requirement of the roof, facilitates the reduction of the heat island effect of buildings, and also causes the service life of water damage preventive measures for the roof to be as long as the service life of the main body structure so that the roof structure can be easily repaired once cracks and leakage occur; and the permeable roof system has the characteristics of easily aviable material, convenience in construction and maintenance and the like.

Description

technical field [0001] The invention is used in the technical field of construction engineering, and in particular relates to a construction method, system and special components of a breathable roof system for building roof energy saving, emission reduction and waterproof construction. Background technique [0002] In the current building technology system, the water damage prevention measures of the flat roof system of house construction mainly rely on physical barriers to isolate water. There are usually two construction methods as follows; one construction method is: roof concrete structure + mortar Leveling layer + 1~2 waterproof layers + thermal insulation layer + 50 thick fine stone concrete protective layer, or lay a ground floor decorative layer on the concrete protective layer by means of slurry; another construction method is: roof concrete Structure + mortar leveling layer + insulation layer + 1~2 waterproof layers + 50 thick fine stone concrete protective layer,...

AI Technical Summary

Problems solved by technology

The above-mentioned roof system construction methods have the following disadvantages: first, the heat island effect of the roof is extremely prominent in hot and high-temperature climates; High requirements for cross-construction coordination

Otherwise, it is difficult for the waterproof layer measures to play a role; third, once the waterproof layer is damaged, it is difficult to determine the location of the problem, which often leads to the complete failure of the roof waterproof system, which inevitably affects the heat preservation and energy saving effect of the roof, and often aggravates the damage of the roof. Deterioration of the concrete structure; Fourth, the repair of the roof system involves a large area, which consumes materials, labor and time, and produces a large amount of construction slag
