Drainage system - a mandatory elementengineering improvement of a private house. It provides a stable removal of precipitation, preventing the destruction of the foundation due to over-wetting of the adjacent soil. Although plumbing products are increasingly made of plastics, metal drainage systems remain the most reliable and durable. But due to the impressive weight and complexity of processing steel elements can cause a lot of problems during installation.
When choosing a metal drain important rolewill play a protective coating evaluation. If the structure is located on the street, its surface is often in contact with water, and therefore must be treated with an anti-corrosion coating. Today galvanized metal drainage systems are common, but this is not enough. Technologists offer additional passive layers and a primer. The result is a multi-level protective "pie", the average guarantee for which is about 20 years. But, of course, and at the price of such a drain is expensive.
Then you can proceed to the choice of form.The traditional execution is considered a semicircular gutter, there is no special reason to refuse it. The only alternative is the drainage metal systems of a rectangular shape, but such a cross section is more difficult to integrate into the typical roofing space. At a minimum, more space will be required for fasteners.
The gutter line is the most responsiblepart of the whole structure. It is located on the hooks, which are securely fixed by hardware - screws, screws, bolts, etc. This can use different approaches to fixation in terms of the placement of fasteners. Bearing structures can be installed on the eaves overhang, boardwalk, rafter foot or crate. It is important that in each case the edges of the roof are located on top. Metal drainage system on adjustable brackets in terms of mounting options gutter the most practical, as it allows you to adjust to any angle of the roof slope. Also you should not forget that the dimensions of the brackets with the carrier holders must correspond to the parameters of the drain in terms of design and especially weight, otherwise the load will simply collapse the system.
After you have determined the method of attachmentholders to the base, you can count the specific installation point of the supporting chute. This is an important point, since the performance of a horizontal drain depends on it in principle. Initially, it is determined in which direction the drain will direct the accumulated water. Then the installation line is marked with a correction for the so-called intentional curvature. This is a technological bias, the degree of which will depend on the departure of the slope and the cross section of the gutter of the metal drainage system. The channel size in depth reaches an average of 110-125 mm, which causes a slope exposure of about 20 mm per 1 m. But another moment should be taken into account related to the lengthening of the drain line. If the gutter forms a channel with a length of 12 m or more, then there will be no point in making a bias in one direction. The best option is to divide the line into two differently directed contours with the calculation of a smaller angle.
From the gutters the channel passes to the funnels and pipesalong which water flows down. Accordingly, installation of fasteners along the vertical line on the facade will be required. For fixation of pipes, special holders are used, consisting of clamps and hardware, which are directly integrated into the walls. It is very important to choose a fastener suitable for a specific foundation so that it does not collapse the structure under heavy loads.
As a rule, in the installation of metal drainagesystems use long screws, anchor rods and thick nails. The most reliable method of fastening will be a gripping clamp plate, which is fixed at the edges with screws of a small format. As for the holders' placement points, manufacturers recommend maintaining a distance between elements of about 2 m. If two pipes are to be connected along one vertical line, then a junction should be provided under the joint, regardless of the pitch set.
In the presence of high-quality mountinginfrastructure with holders of problems with further installation will not arise. Assembly begins with a line of grooves, the segments of which are connected to each other using shaped parts, clamping sleeves or even waterproof glue. But for metal it is desirable to use structural connectors. Then you can proceed to the integration of the funnel to drain. It should be noted here that it is not always possible to assemble the system strictly according to the parameters of the existing elements of the kit, so there is a need for machining. Cut metal gutter systems should be an electric jigsaw of appropriate power or a circular saw with a suitable format. Then go to the junction with a vertical pipe, which is clamped in the previously installed holders with clamps.
Common errors in the design and installation of drainage systems include the following:
So that the water does not fall into the ground near the foundation,should consider the final place of discharge of water. In this capacity, a septic tank, a central sewer drain, or a lake near the house are used. If there are no such opportunities, then it is possible to organize the drainage infrastructure for servicing the metal drainage system. With your own hands, it is easy to assemble this drainage basin - it is enough to make a trench or a small well, then waterproof the bottom and make a filter bed of rubble and sand. Next, it remains to direct the drains from the drain pipes into this channel, having previously closed it with a turf or a special protective structure.
Improving the collection system is not easythe task of maintaining the engineering functions of the building. It is also a way to decorate the facade. The correct choice of metal drainage system for aesthetic properties will emphasize the advantages of facing the house and roofing. The most common textural solutions are brown, dark green and red. It is possible to preserve the natural silver shade of the metal, but, again, its structure must in any case be protected from corrosion and other damage. Additional fixing elements can also add their own stylistic shade. This applies to couplings, brackets, plugs and other mounting hardware. As independent decorative accessories, designers also recommend using gargoyles on drain pipes with metal chains from gutters that complement the drain construction.
