Roof gutter refers to the concave part between the two hips of the building roof. Roof drainage is divided into organized drainage and unorganized drainage (free drainage). Organized drainage generally collects rainwater into the gutter and then discharges it from the rainwater pipe. The gutter for collecting rainwater is called gutter, which is divided into inner gutter and outer gutter. Inner gutter refers to the gutter in the outer wall, which generally has a parapet; The outer gutter is the gutter that picks out the outer wall, and generally there is no parapet.
Benefits of installing gutter
There is no rainwater ditch on the roof of traditional houses, and rainwater will flow down the external wall of the house, leaving water stains directly, which seriously affects the service life of the external wall of the house. The ground will also form ditches or accumulated water due to rain, which will affect your travel and cause damage to your building base.
The biggest function of rain gutters is to prolong the service life of buildings, so it is solemnly recommended that you install rain gutters. The early concrete rain gutters mainly have the following shortcomings:
1 will produce black spots because of raindrops.
Ruptured by years of oxidation.
Once installed, it cannot be replaced.
The gutter system we produced is integrated with the architectural style of the building through decorative cornice design, which solves the disadvantages of no gutter and concrete gutter, reduces the self-weight of the building, improves the aesthetic feeling and grade of the whole building, and is reasonable in structural design, simple and practical, convenient to install, good in toughness, good in low-temperature impact resistance, and integrates aesthetics and practicality.
Determination of drainage ditch size
The size of the gutter is generally determined according to the catchment area of the roof.
5 "K-shaped gutter, which is used in general family houses.
7 "K-shaped gutter is used for roofs of large buildings.
Semi-circular gutter is generally one inch larger than K-shaped gutter to ensure the same rainwater capacity as K-shaped gutter.
The larger the gutter size, the higher the requirement for the firmness of roof and cornice materials. Considering that the rainwater on the steep slope roof may rush out of the gutter, the size of the gutter can be increased accordingly.
How to determine the size of downpipe?
The diameter of the downspout is determined according to the roof water collection. 2*3 downpipes can meet the roof water collection of 60m2, 3*4 downpipes can meet the roof water collection of120m2, and 4*5 downpipes can meet the roof water collection of 200m2; 5-inch K-shaped gutter is generally equipped with 2*3 downpipes; 3*4 downspouts are not easily blocked internally.
