Gutter systems are used to collect rain and melt water from the roof surface. Consider how you need to properly fix the gutters so that the system works efficiently.
Materials for drainage systems
Modern roof drainage systems depending on the material of manufacture can be divided into two large groups:
- Drains made of steel and various alloys;
- Plastic gutters.
Drainage systems made of galvanized steel are the traditional solution. Recently, however, polymer-coated metal parts have been more commonly used.
In this case, the gutter system will cost a little more, but it can also last two to three times longer than when using galvanized parts.
Roof gutters made of copper or zinc-titanium alloy are classified as elite, they are distinguished by the highest performance, but are very expensive.
No less often use plastic drainage systems. This option is quite practical, since the material is inexpensive, it is easy to install and it is not subject to corrosion.
Stages of installation of the drainage system
Installation is carried out in several stages:
- Install fasteners for drains, not forgetting that the gutter must be at a certain slope.
- Install funnels and gutter plugs;
- Lay the gutter drainage from the roof in place;
- Connect the individual elements of the gutter into a common system;
- Install a drainpipe.
Consider how the drainage system is fastened.
Fasteners used in weir systems and methods for their installation
Special brackets are used to install and hold the gutter. These parts are produced in different configurations and from different materials.
As a rule, the material of the brackets is selected in accordance with the material of the gutter and other parts of the drainage system.
There are several ways to mount the brackets:
- On the frontal board of the roof.This method is used when installing a drainage system on an already finished roof or during its repair. Most often, this method is used when installing gutters made of plastic.
- And how to fix gutters if there is no frontal board in the roof structure? In this case, the brackets are fixed to the rafter legs. If this is not possible (for example, the roof is already covered with roofing material), then metal pins are hammered into the wall of the house, on which a gutter is attached using height-adjustable pins.
- Another option for installing brackets is to mount on the roof sheathing or on the bottom of the solid flooring.
In order to carry out the fastening of downpipes, special clamps are used. The shape of these parts and the system for attaching them to the wall may differ from manufacturer to manufacturer.
Most often, metal clamps are used, reinforced with one long hardware or plastic clamps with two attachment points.
When choosing a type of clamp, you need to consider the following nuances:
- The depth of fastening of the hardware (it must be at least 50-70mm);
- The thickness of the insulation layer on the wall of the building;
- The distance between the pipe and the front wall (it is forbidden to fix the pipe close to the wall).
Advice! In no case should the clamp be strengthened so that its hardware will be in the thermal insulation layer, since such fastening is extremely unreliable.
The collar must not be too tight around the downpipe, especially if PVC pipes are used. The fact is that under the influence of temperature changes, the material somewhat changes its linear dimensions and rigid fastening can lead to the formation of cracks.
Fastening horizontal parts - gutters and drains
At the first stage of work, the horizontal parts of the system are installed. Work is carried out in the following order:
- The length of the eaves is measured and, based on the result, the total length of the gutter is determined. The number of fasteners is calculated, given that the step of the brackets should be 0.6 meters.
- Mark the location of the spillway funnel. It should be noted that the inlet of the funnel should be located 10 mm below the drip on the cornice overhang.
- To carry out the fastening of the gutter, it is necessary to install the fixing brackets. When installing hooks, remember to observe the slope of the gutter. To facilitate the task, first strengthen the hook, which will be located in the highest position. Then attach the bracket, which will be located below all. A rope is pulled between these two parts and the rest of the brackets are already installed along it.
- After the installation of the brackets is completed, a gutter with gutter funnels is laid and fixed on them.
Fastening of vertical parts - downpipe
As a rule, the fastening of the drain is carried out during the laying of the walls, but this work can be done later, after the completion of the work on the roof.
During installation, the following recommendations should be followed:
- Pipe installation is carried out from the bottom up.
- To attach the pins on which the clamps are attached, holes should be made in the wall.
- A mark is attached to the lower clamp (or two lower clamps) - a part of the pipe with a cut corner. Instead of this part, you can install a conventional pipe link and connect it to the entrance to the storm sewer.
- Then all the other links that make up the drainpipe are mounted. Each link must be fixed with a separate clamp, and if the link is 2 or more meters long, then an additional fastener must be installed in the middle part of the pipe.
- The optimal spacing of the clamps is 1.8 meters.
conclusions
As a rule, modern drainage systems are sold complete with all the necessary parts and fasteners.
To answer the question of how to fix the drain, you must carefully read the instructions given by the manufacturer, since each model may have its own nuances of using fasteners.
In any case, the strengthening of all parts must be carried out reliably, since a fallen gutter or a fallen downpipe can cause considerable damage and even lead to an accident.
