What's the difference between eaves and gutters?
Eaves refer to the typical horizontal part with lines and feet at the top in architectural composition, especially the top of the three parts of eaves in classical buildings. Eaves are often called eaves by mistake. Generally speaking, the cornice of the roof refers to the upper edge of the outermost cornice of the big roof, that is, the upper opening, rather than the cornice of the elevator and stairs protruding from the big roof. Another noteworthy place is that "eaves" and "parapet" refer to the highest point of the house facade. At the same time, we should also pay attention to one aspect. The height of the eaves does not include the height of the parapet.
The height of the eaves refers to the roof eaves from the outdoor horizon to the sloping roof, that is, the height of the lowest point. First of all, it refers to the calculation of the height from the outdoor horizon to the eaves of the sloping roof. Secondly, the water tank room, elevator room, roof floating board and apron are not included in the building height. Three, the roof sun room is not calculated into the building height.
The gutter refers to the horizontal gutter under the eaves. It is usually used to receive rainwater from the roof and then lead it to the ground through a standpipe. Gutters are generally divided into two types: outer gutters and inner gutters. In general, the area of the building cannot be calculated by the drainage ditch, and the size of the drainage ditch can be determined according to meteorological data, precipitation intensity and drainage speed. In modern times, gutters are mostly built with building materials such as cement boards. In order to make rainwater flow to the ground quickly and then flow back, high, middle and low edge drainage is generally used. At the same time, a sewer hole is left on both sides of the house, so that it can be directly connected by pipes and then discharged to the ground and then discharged.
