Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of rainwater external drainage, in particular to a rainwater external drainage structure for an inner eave ditch of a parapet. Background Art
[0002] At present, the exterior wall is directly raised as a parapet. When the roof is a concrete structure, it is very common for rainwater to be led out from the root of the parapet above the roof and connected to the rainwater pipe for external discharge. However, if it is a steel structure roof, the usual practice is to lead rainwater into the room through rainwater hoppers, and partially or completely organize the rainwater discharge of the roof by internal drainage. Due to the problem of rainwater leakage in the later stage, in many cases, the steel roof can only choose to abandon the internal gutter, thus limiting the design breadth of the facade shape; the rainwater hopper passing through the roof will cause local cold condensation if the insulation roof is not properly handled; there are many supporting components in the internal gutter of the steel structure roof, which often makes the location of the rainwater outlet contradictory. Utility Model Content
[0003] In view of the deficiencies in the prior art, the utility model provides a rainwater drainage structure for the inner eaves ditch of a parapet, which guides water to the outside of the house through a water diversion channel, an inner eaves ditch and a rainwater gutter, preventing the rainwater gutter from passing through the roof and causing local cold and condensation if the thermal insulation roof is not properly treated. The utility model has simple operation and brings convenience to people.
[0004] To achieve the above objectives, the utility model is implemented through the following technical solutions: a rainwater discharge structure of the inner eaves ditch of a parapet, comprising a wall body, an inner eaves ditch is provided on one side of the wall body, a protective plate is installed on the inner wall of the inner eaves ditch, a water diversion channel is provided on one side of the inner eaves ditch, the water diversion channel is tilted and one end is fixedly installed on one side of the upper end of the protective plate, a rainwater outlet is opened below the wall body, a flashing plate is installed on the side wall of the wall body, a rainwater grate is fixedly installed on one side of the flashing plate by bolts, a water diversion plate is installed on one side of the rainwater grate, and a rainwater gutter is installed in the rainwater outlet.
[0005] Preferably, the rain grate is made of stainless steel, has a thickness of about 3 cm, and has a plurality of through holes on its side wall.
[0006] Preferably, the water guide plate is placed tilted upwards with an angle of about 15°.
[0007] Preferably, a foam or plastic rod material filling seal is provided between the rain gutter and the inner wall of the rainwater outlet and above the flashing plate.
[0008] Beneficial Effects
[0009] The utility model provides a rainwater discharge structure for the inner eaves ditch of a parapet, which has the following beneficial effects: the utility model has a compact structure, and rainwater is led into the inner eaves ditch through the cooperation between the drainage channel and the inner eaves ditch, and the rainwater is discharged through the rainwater grate through the rainwater bucket, so that the rainwater does not have to pass through the roof, but is led to the outside above the roof, which provides better possibilities for the practice and later use effects of projects with the need for inner eaves ditch of parapet in actual engineering, is simple to operate, and brings convenience to people.
