Steel metal roofing structure layer and waterproof layer, although maintaining the original practice, but also in the general board of precast hollow membrane waterproofing layer, so it is inevitable leakage in the parapet and day Gouyan other weak links at the mouth. In particular rigid waterproof roof, the most serious problem is the waterproof layer will remain after the completion of the construction caused cracks leaking cracks There are many reasons: changes in the weather and the sun roof caused by thermal expansion and contraction; when the roof After the force will be warping; foundation settlement or load-bearing wall changes roof sit pulp after contraction causes;. roofing material except change or shrinkage deformation, etc. Therefore, once the steel metal roofing pan of water, dripping, surrounding the pipeline and other nodes must be in strict accordance with design drawings and technical specifications of construction, flood level and smooth with no missing edge off angle dripping pipes do caulking around the dense surface sealed, cornices and roof beams and whitewashed outer side surface prior leveling layer, good job hydropower embedded pipes, lightning protection zone is prohibited after pouring the concrete slab chisel random play. on individual piping around the rear bulkhead must be secondary stratification grouting holes should be the next big small hewn The bell, smooth plastic pipe should be brushed surface after installation, make sure the concrete adhesion and compactness. Ensure quality metal roofing projects is a systematic project. If it is the second construction, it is best to take down the roof overhead compartment thermal layer, insulating layer in the process of taking, not pry hurt the original waterproof layer must be taken after cleaning, rinse, to enhance adhesion. In general, the water layer of protection is not permitted in the roof has been built the wear holes with the pipeline and embedded iron pillar and buried. If additional roof garden on the old building, whether it is the kind of practice roofing layers are not piercing punch holes in the roof and buried iron pillars. Even general equipment unit can not be on the roof, "root", but to take other measures to make them "float placed" on the roof.
