Rainwater systems - constructor for adults
The primary principle of any water intake is a trough, but apart from it the drainage design includes many different details, and it is extremely important to know the purpose of each. Let's start with a simple one, namely, with what is needed to assemble the gutter itself, which can be 2, 3, 4 or 6 meters in length. To assemble a structure from several trays, it is necessary to connect the drainage system elements, the beads of which are provided in the upper part with grippers, in which the edges of the trough are fixed.
In order not to saw the gutter under a corner joint( especially since we do not need extra joints), the elements for the inner and outer corners are used. Another important detail is the expansion element, which is extremely necessary where the gutter length exceeds 18 meters without drainpipes installed on this segment. It is used instead of a standard connection, with brackets for drainage systems installed on both sides of the expander.
Rainfall draining system
Now consider the installation of the drainage system. Rain or melting snow drip into the gutters from the roof slopes and along inclined trays rush to the funnel, where from the pipes merge into surface drainage. And it will be useful to know how these gutters are connected to the pipes. Used for this purpose is a kind of adapter, mentioned above - a funnel, and there may be several options. In addition to the conventional funnel with outlet throat, the expansion funnel is widely used, with the functions of the corresponding connecting element .Sometimes an inclined funnel is required, the neck of which is at an angle.
If you do not know exactly at what angle the pipe will tilt at the top, take an adjustable inclined funnel, the position of the neck of which changes arbitrarily.
To the nozzle of the funnel from below, either a straight-line straight pipe with an extension or a drainage knee that provides a turn of 45, 60 or 75 degrees is attached. Quite interesting is the option, as a transition element of two parts, each of which can be bent at the right angle. In the middle of the drain, a branch( tee) can be installed. In the lower part, the drainage system either goes to a regular drain, in this case a tip with a hole that is smoothly bent downwards, or into a manifold, is installed, for which the nozzle is placed under the diameter of the point header.
The gutter is based on the little things
And it really is. Connecting elements, brackets, yokes - all these seemingly small parts play a big role in the formation of the rainwater system. So, for example, the drainage device is impossible without brackets that support the gutter along the entire perimeter of the building. These fasteners are of several types: steel super long( 37 cm), long( 31.5 cm), short( 19 cm) and ultrashort( 3.9 cm), as well as plastic, for which a special wedge is sometimes necessary in case of installation of trays on an inclined cornice.
Clamps are different, both steel and plastic. The first are divided into 2 types - with paws( fixation with screws) and with a pin, the second are fixed with a screw from the inside, and after installation the pipes are closed with a removable segment. Also, a snap ring is put on the pipe, above the upper clamp, so that when the fixing is loosened, the drain can not be allowed to slide down. To avoid clogging of drains on the funnels are installed rain gutters, which, if necessary, are easily removed and cleaned.
