Introduction of waterproof construction of roof and wall
The structural layer of waterproof roof should be cast in situ as a whole. When precast reinforced concrete hollow slab is used, the roof slab should be grouted with 0# mortar, C20 fine stone concrete should be grouted carefully, the grouted concrete should be mixed with micro-expansive agent, and each joint should be grouted twice. When the joint width of the roof plate is greater than 40mm, structural reinforcement must be set in the joint, and the joint at the plate end should be sealed. After the initial setting, it should be cured for one week, and the drainage should be checked for leakage.
First, the setting and practice of frame joints
Frame joints should be set at the supporting end of the roof panel, at the corner of the roof, at the junction of the waterproof layer and the protruding roof, and should be aligned with the joint of the roof panel, so that cracks in the waterproof layer caused by temperature difference, concrete shrinkage structural deformation and other factors can be concentrated at the frame joints to avoid cracking of the panel. The spacing between frame joints should not be too large. When it is more than 6m, a V-shaped frame joint should be set in the middle, and the depth of the frame joint should run through the thickness of the waterproof layer. When the frame joint is also used as an exhaust duct, the frame joint can be widened appropriately and an exhaust hole can be set for exhaust. When oil, asphalt and linoleum are used as the waterproof layer of the roof, linoleum with a width of 200 mm ~ 300 mm should be added to the frame joints, and asphalt glue should be pasted on one side, and ointment should be embedded in the frame joints.
Second, the roof leveling layer practice
The roof adopts the method of combining architectural slope finding with structural slope finding. First, find the slope according to 3% of the structure, then use 1: 6 cement expansive concrete stone to find the slope on the structural layer, and then make a 25mm thick cement mortar leveling layer. When looking for a slope in a building, be sure to find out the flooding slope and the direction of water flow, and straighten, dot, pat and water the outlet with fishing line between the highest point and the outlet, with a thickness of not less than 30 mm.
Third, the practice of roof isolation layer
The importance of roof insulation should be emphasized here. In areas with heavy acid rain, high humidity and strong corrosiveness, the common practice of general construction units is to brush cold priming oil on the leveling layer as an isolation layer, and then? Just poured rigid waterproof layer, in order to ensure that the roof does not leak during the three-year warranty period, two cloth and three oil waterproof layers are made on the rigid layer. When the project was accepted, Party A saw that the roof was black and beautiful. In fact, applying ointment to the surface layer is easy to age and its service life is not long. Three years later, it will come to repair the leak. In order to avoid this situation, in the construction, adjust measures to local conditions, learn from each other's strong points, and make this waterproof layer of two cloth and three oil coils between the leveling layer and the rigid layer, which not only plays the role of isolation layer, but also prevents the ointment from aging and waterproofing.
