Water leakage preventing structure for roof parapet wall and construction method thereof

Abstract

The invention discloses a water leakage preventing structure for a roof parapet wall and a construction method thereof. The water leakage preventing structure comprises a C20 plain concrete flashing poured on a roof external edge beam and a waterproof layer laid on roof floor slabs; a plurality of evenly-distributed expansion joints are formed in the C20 plain concrete flashing; round corners arearranged at the junctions of the C20 plain concrete flashing and the roof floor slabs, and a brick laying body is arranged on the C20 plain concrete flashing; and the waterproof layer comprises a polymer modified asphalt waterproof coiled material, a heat insulating layer, a slope finding layer, a leveling layer and a rigid whole pouring layer which are laid sequentially. According to the water leakage preventing structure for the roof parapet wall and the construction method thereof, the C20 plain concrete flashing with the height being 300 mm is poured on the roof external edge beam, the C20plain concrete flashing and a roof are both made of concrete, therefore, cracks are not prone to occurring on the junction of the wall bottom of the parapet wall and the roof, and the problem of water leakage of the parapet wall can be effectively avoided.

Description

technical field [0001] The invention relates to the technical field of water-leakage-proof structure of a parapet wall, in particular to a water-leakage-proof structure of a roof parapet wall and a construction method thereof. Background technique [0002] At present, water leakage often occurs at the position of the roof parapet, many of which are due to the fact that the parapet is all constructed with brick masonry. Since the brick masonry and the concrete floor are two different materials with different coefficients of thermal expansion, transverse cracks will appear at the junction of the two, which may tear the roof waterproof layer and cause water leakage. Contents of the invention [0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a roof parapet water-proof construction method with simple construction and better quality. It is made of the same material as the roof through the reverse sill of C20 plain ...
