Installation and construction of drain pipes with their own hands

Installing the ventilation pipe with your hands requires maximum precision necessary to cut it to the hole in the roof, because it will be very difficult to close the large gap.

are two types of gutters depending on roof design: pendant and wall.

On workbench perform painting wall gutters.The double picture short side sheets are connected to each other arranged in the direction of water flow double bed-folds.

On one of the long sides of the picture are folded edge needed to connect with ordinary coated.Stepping back from the other long side of 200-250 mm on the short sides make one incision 30 mm deep, and then along the long folded edge otvorotnuyu tape at an angle of 60 ° to the plane of the picture.Under the dual recumbent folds the corners of the edges are cut at 45 °.Depending on the amount of annual falls in the area rain gutter board is folded to a height of 120-150 mm.

The next step on the short sides of the picture under the recumbent folds folded edge: paintings from the gutters to the right of rainwater, making the left folds down and the right - up.Wall spout is attached directly on the edge of the roof, because it is used in the absence of overhang.

most common suspended gutter with drain sheet.In general, they are semicircular, but in some cases there are also rectangular.

Their functioning is manufactured from steel sheets having a thickness of 4 mm, a length of 3.4 m and a width of 25 mm.Sheets in the film are connected by means of double folds lying face down, and so they were on the outside of the gutter.The finished picture arch using a mallet on a special fixture.At the end of not joining the gutters funnels put caps.

order not to violate the stylistic unity of the wooden house, using pre-impregnated with an antiseptic, box gutters, hollowed out half of the log.You can make a collar for drain pipes of galvanized if desired.

tube processing methods

versions add color.When the scale and rust are removed, iron thoroughly washed with running water and then dipped into a prepared one of the following recipes for the blackening solution.

1. Water - 200 pieces;sodium hypo - 16 pieces;ammonium chloride - 12 parts;Phosphoric Acid - 1.4 parts;nitric acid - 0.6 parts.

solution gradually brought to a temperature of about 70 ° C and placed it in the iron by approximately 20 min.As a result, it is covered with a black matte film.

exerts its effect solution can and at a temperature of 20 ° C.

The product in this case it is necessary to keep it at least one hour.As a result, matte black film appears on it, but less strong than at 70 "C.

2. Water - 200 pieces;caustic soda - 130 pieces;sodium nitrate - 35 parts.

in bringing to a temperature of 135 ° C, the solution is lowered to 1.5 hours of iron, which is covered by a shiny black film as a result of this procedure.

3. Water - 200 pieces;caustic soda - 300 pieces;sodium nitrate - 6 parts.In

brought to a temperature of 150 "C, the solution is not more than 10 minutes, the product is placed, which is covered in the matte black film.

finished products procedure, first washed with hot water and then dried in the open air, and then put them on a thin layer of a natural drying oil.

the wall and the chimney above the roof drainage is the level of not less than 150 mm.

WAGs rounded inner angle of the roof sheets are stacked overlap by at least 100 mm.

diameter drainpipe is dependent on the amount of water flowing into them.Thus, the diameter of the drain pipe for a roof having an area of ​​30 m2, is 80 mm;for the roof, which has an area of ​​50 m2 - 90 mm;for the roof, having an area of ​​125 m2 - 100 mm.Installation of drainage pipes installed at a distance of at least 30-35 mm from the wall and with the aid of pins immured with tongs and clamps attach to it.To not rusted pins, they should be pre-galvanized or cover any anti-corrosion compound.
