Roof cornice water accumulation preventing structure

Abstract

The invention relates to a roof cornice water accumulation preventing structure, and belongs to the technical field of cornice water accumulation prevention. The water accumulation preventing structure comprises a wall, a cornice, a first drainage pipe, a second drainage pipe, a filter screen and a brush plate, and the cornice is fixedly connected with the outer wall of the wall; a catchment trough is formed between the inside wall of the cornice and the outside wall of the wall; the upper end of the first drainage pipe is fixedly connected and communicates with the bottom of the catchment trough, and the lower end of the first drainage pipe is fixedly connected with the wall; the second drainage pipe is fixedly connected with the cornice, and one end of the second drainage pipe penetratesthrough the cornice, and communicates with the catchment trough; the other end of the second drainage pipe faces the direction far away from the cornice; the filter screen is arranged in the catchment trough horizontally, and connected with the inside wall of the catchment trough fixedly; and the brush plate is slidably connected with the top side of the filter screen. The water accumulation preventing structure has the effects that the water accumulation of the cornice can be avoided, and the water seepage of the wall is avoided.

Description

technical field [0001] The invention belongs to the technical field of eaves anti-water accumulation, and in particular relates to a roof eaves anti-water accumulation structure. Background technique [0002] The cornice refers to the top of the roof structural slab at the junction of the outer wall of the structure and the roof structural slab, and also refers to the typical horizontal part on the top of the architectural composition with protruding lines, especially the uppermost part of the three parts of the eaves of classical buildings. "Eave" is often mistaken for "along mouth". Generally speaking, roof cornice refers to the upper edge of the eaves at the outermost edge of a large roof, that is, "shangkou". [0003] The types and shapes of the existing eaves are basically fixed. During the long-term use, some problems have appeared in its water resistance. For example, the drainage pipes are easily blocked by debris, resulting in water accumulation inside the eaves If...

Problems solved by technology

[0003] The types and shapes of the existing eaves are basically fixed. During the long-term use, some problems have appeared in its water resistance. For example, the drainage pipes are easily blocked by debris, resulting in water accumulation inside the eaves If the accumulated water is not treated for a long time, it will cause water seepage in the wall, and when the old-fashioned cornice encounters heavy rain, because the rainfall is greater than the drainage, the cornice will overflow, and the rainwater will pour into the wall, causing water seepage in the wall
