Roof waterproof construction method

Abstract

The invention provides a roof waterproof construction method, and belongs to the field of waterproof technology of buildings. The roof waterproof construction method comprises the following steps: industrial gasoline is added in chloroprene rubber asphalt adhesive for diluting, the two substances are evenly mixed, and the mixture is brushed on the cleaned surface of a substrate; then, a coiled material is laid after the brushed mixture is kept at normal temperature for 4 hours; during pavement, the joint place of the substrate and the coiled material is heated by a flame spray gun when the coiled material is uncoiled; the distance from the flame spray gun to the heated surface is 300 mm; when the surface of the coiled material is just molten by reciprocating heating, the coiled material is forwards rolled, laid and bonded; the coiled material is upwards laid from cornices and parallel to the ridge; for the bidirectional flowing slope, the coiled material is in lap joint in the flowing direction; the lap joint widths of the long edges and the ends of the coiled material are both 80 mm; and joints of the ends are staggered by 50 mm; the lap joint place of the coiled material is heated with the spray gun and the bonding is reinforced by the heating; and the closing head of the tail end is tightly filled with sealant.

Description

[0001] technical field [0002] The invention belongs to the technical field of building waterproofing, in particular to a construction method for roof waterproofing. Background technique [0003] Building seepage is a relatively common quality problem in buildings, and it is also the most intense problem reported by residents. Many residents found that the roof leaked, the walls penetrated, and the plaster layer fell off during use. Day after day, the roof and inner walls would peel off in large areas due to leakage, and moldy and smelly due to long-term leakage and humidity , directly affect the health of the residents, not to mention the interior decoration. Offices, machine rooms, workshops and other workplaces such as long-term leakage will seriously damage office facilities, precision instruments, machine tools, etc., and may also malfunction due to mildew, and even cause electrical short circuits. In the face of leakage, people will spend a lot of manpower and mater...

Problems solved by technology

Many residents found that the roof leaked, the walls penetrated, and the plaster layer fell off during use. Day after day, the roof and inner walls would peel off in large areas due to leakage, and moldy and smelly due to long-term leakage and humidity , directly affect the health of the residents, not to mention the interior decoration

Offices, computer rooms, workshops, etc. If long-term leakage will seriously damage office facilities, precision instruments, machine tools, etc., they may also fail due to mildew, and even cause electrical short circuits
