Waterproof structure of building exterior wall top

Abstract

The invention relates to a waterproof structure of a building exterior wall top, and relates to the technical field of building construction. The waterproof structure comprises a top wall, a female wall and a waterproof layer, wherein the top wall is connected with the female wall; the waterproof layer is laid on the top wall; a drainage channel is embedded between the top wall and the female wall; the drainage channel is lower than the waterproof layer; a drainage pipe is embedded in the female wall; the drainage pipe communicates with the drainage channel; the drainage channel is further provided with a filtering mechanism used for filtering impurities; the filtering mechanism comprises a filtering roller, a scraper and a driving assembly; the filtering roller is rotatably connected to the drainage channel; the outer circumferential surface of the filtering roller abuts against the side wall, away from the female wall, of the drainage channel; the scraper is arranged on the side, close to the female wall, of the filtering roller; one end face of the scraper abuts against the outer circumferential surface of the filtering roller; and the direction of the speed of the contact portion of the filtering roller and the drainage channel is opposite to the direction of the speed of rainwater flowing through the portion between the drainage channel and the filtering roller. The waterproof structure of the building exterior wall top has the advantages that the probability that the filtering mechanism is blocked can be reduced, the drainage efficiency of the building exterior wall top is improved, and the probability that corrosion and moisture leakage occur on the wall top is reduced.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a waterproof structure on the top of a building exterior wall. Background technique [0002] Building waterproof engineering is a sub-project to ensure that the structure of buildings (structures) is not invaded by water and the internal space is harmed by water. Building waterproof engineering occupies an important position in the entire construction project. The building waterproofing project involves the basement, wall, floor, wall, roof and many other parts of the building (structure). Its function is to make the building or structure prevent rainwater, production and domestic water leakage and The erosion of groundwater ensures that the building structure and internal space are not polluted, and provides a comfortable and safe living space environment for people. [0003] At present, the country advocates the construction of sponge cities, that is, planting ve...

[0005] In view of the related technologies mentioned above, the inventor believes that the sundries are blocked by the anti-clogging filter screen on the side away from the drainpipe. During the flow of rainwater, the sundries will be blocked again on the anti-clogging screen, thereby reducing the building exterior. Drainage efficiency at the top of the wall
