Inverted waterproof insulation roof structure and construction method thereof

Abstract

The invention provides an inverted waterproof insulation roof structure and a construction method thereof. The inverted waterproof insulation roof structure comprises a roof concrete structural layer,a roof waterproof layer, a roof additional waterproof layer, an isolation layer, a roof concrete protective layer and a roof surface layer from bottom to top. The roof waterproof layer is made of hard foam polyurethane waterproof insulation coating, the roof additional waterproof layer is made of one-component polyurethane waterproof coating, the isolation layer is made of a polyvinyl chloride plastic film, and the roof surface layer is made of one-component polyurea coating. According to the inverted waterproof insulation roof structure and the construction method thereof, the integrity anddurability of insulation and waterproofing under a complex roof environment are improved greatly, construction is easy, the waterproof and insulation performance is good, the load is light, and the compressive strength is high. At the same time, an insulation layer and a mortar leveling layer are omitted, manpower id saved, the construction efficiency is improved, and the economic benefit is improved. In addition, hard foam polyurethane is stable in chemical property and environmentally friendly.

Description

Technical field [0001] The invention relates to a novel roof structure and a construction method thereof, in particular to an inverted roof structure and a construction method thereof. Background technique [0002] Traditional thermal insulation roof construction methods include two types: upright roof and inverted roof. [0003] The upright roof structure generally has a thermal insulation layer under the waterproof layer. The materials for the thermal insulation layer are generally perlite, cement polystyrene board, aerated concrete and polystyrene board (EPS). These materials generally have a common problem of large water absorption. Water absorption will greatly reduce the thermal insulation performance and cannot meet the requirements of thermal insulation. Therefore, it is necessary to put a waterproof layer on top of the thermal insulation layer to prevent the penetration of water and ensure the drying of the thermal insulation layer.
