At present, following three kinds are mainly contained for the construction method roofing of seepage occurs carrying out waterproof repairment:
Method one: original roof structure is all cut to roofing concrete structural slab, then traditionally Roof system structure way again each procedure is constructed one time, with upper part, globality renovation is carried out to roofing floor.But carry out roof maintenance construction in this way, engineering cost is higher, long in time limit, and also can bring noise and dust pollution.
Method two: original Roof system is not destroyed while roofing is keeped in repair; original roofing surface layer is laid one waterproof roll or construction one waterproof coating again; as pitch class waterproof roll or the polyurethane waterproof coating of constructing; after waterproof construction, also need to construct again one mortar or concrete cover on waterproofing course.The advantage of this method is that construction cost hands over roof overall to overhaul (method one) cheaply, but can increase roof load, and then can affect building use safety as exceeded architectural design weight bearing power, construction cost is also higher.
Method three: indoor local grouting leak-stopping is carried out to the floor of roof leakage, or waterproofing and leakage-stopping maintenance is carried out to the local of seepage roofing.But because this way does not form overall water proof structure, easily again channeling water occur at the weak part of roofing and produce seepage, therefore this method does not thoroughly solve roof leakaging problem, can only respite roof leakage present situation.
At present, the construction method of carrying out insulating reform for the roofing of effect of heat insulation difference mainly contains following two kinds:
Method one: the little light material of coefficient of thermal conductivity is set in roof structure and is used as thermal insulation, as expanded perlite, glass wool, polyethylene or polystyrene foam etc.This method needs reform waterproofing course and topping, and comparatively complicated, expense is also larger.
Method two: on the roof of hot summer and warm winter region and hot-summer and cold-winter area, traditional heat insulation and heat control method also often adopts built on stilts mode of ventilating, and namely at roofing tiling overhead heat insulation stool, or makes somebody a mere figurehead tiling isolation layer with fragment of brick, make air in Stilt layer current downflow, the heat of roof surface can be taken away.This way is relatively simple, because cross-ventilation heat radiation, the effect of heat insulation of roofing is also better, but is only applicable to the non-accessible roof of parapet height lower than heat insulation stool height, and is not suitable in violent typhoon area using, otherwise has high-altitude and to blow off risk.
