Aesthetic and attractive type of drainage systems are adorned by any private house. Correctly matched and located gutters and water intake hoppers testify to a properly protected roof from the weather. You can construct a catchment composition for the "Waltz of the Rain" with your own hands. It will be enough to make simple calculations, pick up a drainage system from the manufacturer and install it. How to do this? Yes, it's very simple!

Gutter system at home
An important integral part of the building of a private house is the drainage system, which protects the roof from getting wet. It is known that the absence or poorly executed installation of a drainage system can lead to damage to the facade of the building or house.
In addition, properly made installation of drainage system will ensure the safety of the foundation and supporting structures from the aggressive force of melt water and rainwater.
Choosing a drainage system, it is necessary to take into account the climate conditions of the house location, taking into account the maximum period of rain, the geometric features of the existing roof and its material, the angle of slope of the ramp.
The algorithm for assembling and installing the drainage is the same for all materials of the system. Naturally, the installation will depend on the sequence of assembly and installation of elements of the roof drainage system.
Gutter system installation
drainage systems, material selection and cross-sections
The product range of the manufacturer of drainage systems is divided into several types:
• Plastic products
• metal products.
Plastic drainage systems feature high resistance to daily mechanical damage and temperature conditions. For example, the drainage system profile (PROFIL) excellently copes with the precipitation of atmospheric precipitation due to the use of connecting elements and rubber seals.
The profile of the drainage system made of metal can be round "Scandinavian" and rectangular - "American". A drainage system with a circular cross-section is most preferable for houses located in areas with cold climate and temperatures.
The design of the gutter cross-section is capable of pushing the ice outward. The rectangular cross-section type of the drain can accommodate a significant amount of water without overflowing beyond the gutter. This is the best option for warm areas.
Gutter system of metal with plastisol coating of 100 microns on both sides is the best offer of manufacturers of drainage systems.
For example, the technical parameters of the gutters of the Metal Profile system with the thickness of the galvanized layer - 275 g / m², the diameter of the pipe - 100 mm and the diameter of the gutter - 125 mm with the semicircular cross-section of the drainage are safely suited for the structures of houses of any design.
You can assemble and install such a drainage system by yourself.
It is enough to study the installation instructions for the drainage system.
Recall that the drainage system from the manufacturer consists of the elements:
• gutters and funnels of catchments
• risers and elbows connecting
• Fasteners
• plums.
The general technology of assembly and installation of the system consists of the stages: "mounting fasteners" - "installation of funnels and gutters" - "drainage organization" - "assembly of knees and risers".
Preliminary it is recommended to make a simple calculation of drainage system.
Calculation of the drainage system
calculation of roof slope area and number of angles
The calculation of the drainage system begins with the determination of the standard size of the diameter of the drainage and the number of angles. For this, we calculate the area of the roof slope. For a ramp area from 60 to 100 sq. M, it is recommended to choose a small drainage system, for an area of more than 100 sq. M - a large system (a small system offers a pipe diameter of 90 mm and a 125 mm diameter of a trough).
Calculation of the number of corners of the system depends on the configuration of the roof. For example, a gable roof means the placement of gutters on all sides of the ramp. Thus, according to the roof configuration it will be 4 outer and 2 internal corners.
calculate the number of gutters
Gutters for sediment removal have a standard length of 3 m. Determine the length of the eaves, by adding the lengths of all sides of the roof. The resulting amount is divided by the length of one gutter and, rounding the result, we get the necessary number of gutters.
calculation of the number of connectors, funnels and plugs
Gutter connectors are used at each joint, as well as at the junction of gutters and corners.
Trench plugs are installed on the ends of the trough using a rubber seal.
For installation of one funnel the recommended length of the gutter should be 10 m, and between two funnels not less than 20 m.
calculation of the number of hooks for external fastening of gutters
The distance between the adjacent hooks of fixing the drainage system depends on the material of the manufacture of the elements of the system. So, for a steel system this distance is 500-900 mm, for a system of copper - 300-600 mm. In addition, to strengthen the design of the drainage system, in the junction of gutters and corners, install additional hooks. For the curtain overhang and rafters are long hooks, and for the front board and the end of the rafters - short.
calculation of the number of risers
The calculation of the number of risers should be based on the calculation of the number of funnels. Therefore, the resulting estimated number of funnels will be the beginning of the installation of risers. Each gutter runs around the cornice overhang. To drain the sewage, knees are required, which are calculated from the quantity of 2 pcs. per each riser.
In the lower part of the riser, piping should be provided.
For more detailed calculation of the drainage system parameters, it is recommended to use on-line calculations from the Internet.
Installation of drainage system
we form the gradient
The correct installation of the drainage system is carried out taking into account the organization of the slope of the gutter. Forming and creating a slope is made using fasteners, which are recommended to be installed with a drop in the level for each running meter.
The slope is formed in the direction of the funnel of the water intake. For plastic troughs fasteners are made with an interval of 60 cm, for metal troughs this distance is 80 cm.
we manufacture the fasteners
Mounting of fasteners for gutters is made in several ways, which depend on the way the roof is organized:
• install fasteners on the roof lathing
• on the windboard or every rafter.
installation of gutters and funnels
Installation and installation of gutters are performed using connecting segments. The water intake hoppers are installed in places of the slot of the receiving hole in the gutter. Recall that the diameter of the funnel and the diameter of the hole in the chute should match the size.
Funnels are attached to the gutter using special clamps, by pre-sealing the joint junction. In addition, it must be remembered that the connection to the waste receiving funnel is carried out by means of taps having different shapes and bending angles.
The correct layout allows you to select the appropriate docking configuration.
