A kind of water-flooding construction technology of building roof parapet wall

Abstract

The invention relates to a flashing structure construction process, in particular to a building roof parapet wall flashing construction process. The building roof parapet wall flashing construction process comprises the following steps that step one, a flashing wall body of a reinforced concrete structure is poured on a building roof; step two, a waterproof roll is paved and pasted on the inner facades of the roof and the flashing wall body to form a waterproof layer, and the upper end of the waterproof roll is subjected to head retraction treatment; step three, a protective brick wall is laid on the outer facade of the waterproof layer through solid bricks, the inner facade of the protective brick wall is tightly attached to the waterproof roll, and the waterproof roll is tightly pressed on the flashing wall body, wherein the protective brick wall is no larger than the flashing wall body; and step four, a parapet wall is laid on the flashing wall body through solid bricks on the basis of the top of the flashing wall body, wherein the thickness of the wall body of the parapet wall is equal to the distance between the outer facade of the flashing wall body and the outer facade of the protective brick wall. A flashing structure built through the building roof parapet wall flashing construction process has the advantages of being resistant to cracking and falling-off and long in guarantee period and is convenient to construct and low in cost, and materials are convenient to obtain.

Description

technical field [0001] The invention relates to a construction technique of a flooding structure, in particular to a construction technique for flooding of a parapet wall of a building roof. Background technique [0002] The flashing structure (referred to as flooding), that is, the waterproof structure between the roof waterproof layer and the protruding structure, the junction of the roof waterproof layer, the parapet, the chimney, the stairwell, the riser and other walls protruding above the roof and the roof. Extending to these vertical faces, a vertical paved waterproof structure is formed. At present, the construction of building roof parapet flooding generally adopts the following steps: laying waterproof coiled material on the brick parapet wall as a waterproof layer, and brushing a layer of mortar on the waterproof coiled material as a protective layer of the waterproof layer. The flashing structure formed by such a construction process is prone to cracking of the ...

AI Technical Summary

Problems solved by technology

The main reasons for the aging, falling off, drumming and cracking of the waterproof membrane are: the cracking of the flooded wall causes the waterproof membrane to fall off, crack, and the waterproof layer is damaged; the protective layer is attached to the smooth surface of the waterproof membrane, and the protective layer and the waterproof membrane Insufficient adhesion, the protective layer is easy to fall off and loses its protective effect, which makes the waterproof membrane exposed, and the aging of the waterproof membrane is accelerated under the sunlight, thus gradually losing its waterproof effect
