Embodiment Construction

[0020] The present invention will be further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention.

[0021] For the waterproof construction method at the junction of the parapet root and the roof concrete structure, the traditional method is to pour the parapet slab after the concrete of the roof beam is poured. There is no self-waterproof effect at the junction of the parapet fence and the roof. The slope of the roof and the drainage direction are all at the edge of the parapet. Long-term rainy or heavy rainwater accumulation often occurs, especially due to construction defects of the waterproof layer or aging of the waterproof layer. Roof water leaks to the insulation layer and the slope layer, resulting in long-term water accumulation on the roof causing water seep...

Abstract

The invention discloses a waterproof construction method for a joint of a parapet root and a roof concrete structure. A parapet is upturned by 300mm, and a roof panel and a parapet breast board structure form a structural waterproof ring in the range of 300mm above a roof. A roof leveling layer, a slope making layer, a waterproof layer and a protective layer are stacked at the parapet root and are generally not larger than 250mm, even if the roof waterproof layer is aged and leaks, water is accumulated on the heat preservation layer leveling layer for a long time, the roof panel and the parapet breast board structure cannot generate the water seepage phenomenon in the waterproof ring range of 300mm above the roof structure layer, and therefore the influence of water seepage of the roof parapet root on water immersion of an outer wall and a top layer indoor wall face is eradicated.

Description

technical field [0001] The invention belongs to the field of civil engineering, and in particular relates to a waterproof construction method at the junction of parapet roots and roof concrete structures. Background technique [0002] At present, the parapet is the low wall around the roof of the building. The construction joint between the parapet wall panel and the roof panel is left at the junction of the parapet wall panel and the roof panel. The main function of the parapet is not only to maintain safety, but also to Waterproof closures are applied at the bottom to prevent water seepage from the waterproof layer or overflowing rainwater from the roof. The main function of the parapet wall in the building is to do a good job of waterproofing. Generally, the roof is about 250mm thick after slope finding, heat preservation, heat insulation, waterproofing, etc., and the end of the waterproof layer is considered to be rolled up to a height of 250mm. This method is a common ...
