Roof drainage structure

Abstract

The invention discloses a roof drainage structure. The roof drainage structure comprises a building base body, wherein an inner eave gutter is formed in one side of the building base body, an outer eave gutter is formed in the other opposite side of the building base body, the inner eave gutter communicates with the outer eave gutter, and a drainage hole is formed in the gutter bottom of the outer eave gutter; when the building base body is a wall, the outer eave gutter communicates with the inner eave gutter through a through hole in the building base body; roof steel plates extend into the inner eave gutter; and when the building base body is a column, the inner eave gutter includes inner eave gutter walls and an inner eave gutter bottom, wherein the inner eave gutter walls are arranged on the periphery of the column in clearance and surrounding modes and provided with notches facing the outer eave gutter, the two ends of the notches of the inner eave gutter walls are correspondingly connected to an outer eave gutter inner wall, the outer eave gutter inner wall, an outer eave gutter outer wall and an outer eave gutter bottom constitute the outer eave gutter, and the roof steel plates extend into the inner eave gutter and extend into the outer eave gutter from the outer eave gutter inner wall. According to the roof drainage structure, the problems of the water seepage risk at the joint between a steel roof gutter and a wall body and the rainwater leakage caused by the inconsistent shrinkage of a concrete roof gutter and a steel structure roof are effectively solved, and meanwhile, the water-holding capacity of the roof gutter can be effectively enhanced.

Description

technical field [0001] The invention relates to the construction field, especially the roof drainage structure. Background technique [0002] Roof drainage is usually achieved by setting gutters. The traditional structure of brick walls or columns and steel gutters often has joint leakage; at the same time, traditional roof gutters often only have inner or outer gutters. As a result, under heavy rainfall conditions, the water storage and drainage capacity of the gutter cannot meet the drainage requirements, resulting in the risk of water overflow in the gutter and leakage to the joint between the gutter and the steel roof. Contents of the invention [0003] The object of the present invention is to provide a roof drainage structure in order to solve the above-mentioned problems in the prior art. [0004] The purpose of the present invention is achieved through the following technical solutions: [0005] The roof drainage structure includes a building base, one side of th...
