Construction method of concrete roof water leakage repairing system

Abstract

The invention discloses a construction method of a concrete roof water leakage repairing system, and relates to the field of house repairing. According to the method, repairing is conducted through manners of thermal insulation layer internal drainage, thermal insulation layer internal exhausting and ventilating and design of a layer of high-temperature-resistant, anti-aging and waterproof material on the surface of a roof. Thermal insulation layer internal drainage comprises the steps of digging a groove beside all rainwater pipes on the roof to a concrete structure layer, exposing the rainwater pipes, installing a section of water conduit at the bottom of the groove, forming a plurality of holes in the surface of the water conduit for introducing water of a thermal insulation layer, communicating one end of the water conduit with the rainwater pipes, and finally filling a groove body. Thermal insulation layer internal exhausting and ventilating comprise the steps that holes are punched to penetrate through the thermal insulation layer, exhaust ventilation pipes are inserted into the holes, and the exhaust ventilation pipes extend out of the roof and then are bent downwards to point to the roof to exhaust moisture and hot air inside the thermal insulation layer. By means of the method, the roof with leaked water can be effectively repaired, the drainage and ventilation capacity of the roof is improved, and the heat preservation and insulation performance of the roof is improved.

Description

technical field [0001] The invention relates to the field of house repairs, in particular to a construction method for a concrete roof leakage water repair system. Background technique [0002] The traditional roof insulation layer is generally made of perlite, cement polystyrene board, aerated concrete, ceramsite concrete, polystyrene board (EPS) and other materials. These materials generally have the common problem of high water absorption rate. If they absorb water, the thermal insulation performance will be greatly reduced and cannot meet the requirements of heat insulation. Therefore, the design is generally upright waterproof (waterproof design is on the insulation layer), and it must be made of waterproof layer. On top of it, prevent the infiltration of moisture and ensure the dryness of the heat insulation layer, so as to be able to insulate and keep warm. When repairing the roof, an inverted waterproof standard system (waterproof design is under the insulation laye...
