The device downpipes

constituent parts of the drain pipes are rainwater, knee to bypass the projections on the wall, direct links, noting to divert water away from the building wall.

The main parts include rainwater rim, cone and cup.If you want to make their assembling downpipes hands to perform the rim of the funnel is cut blank having a width equal to the length of the upper side of the trapezoid cone blanks, and then the edges are bent for connecting with the cone.The preform arch and connected seam.Then roll out two roll stiffness on the finished beads and rim edge, which roll having a diameter of 14 mm wire.

to want to cut the cone-shaped isosceles trapezoid blank.Its upper side along the length should be equal to the width of the preform for the glass and the underside of the workpiece length should match the width of the rim.On the first preform should bend seamed edges, and then when you need to bend the shaft deflected roll it into a cone on the rolling of.Cone on a generator must be connected seam.The edges of the rectangular billet cup must be connected and compress.At the final stage of a glass tube is inserted into the unit.

material for the manufacture of direct links drainpipes are standard steel sheets, which, depending on the diameter of the drain pipe and the required number of links cut across or along.Then give a slight taper workpiece, shortening one of its sides by 5-6 mm.This is necessary in order to complete the links were good to each other.

preform link with curved edges for the rebate manually roll on the steel pipe, timber, mandrel or roll out to the rolling of.

On Zigmashina direct links to the ends of the roll out protruding above the surface level of 7-8 mm rollers.They limit the depth of approach of one link to another and are ribs.

Knee am corrugated, made of straight pipe unit, which is bent using a press, or a non-corrugated, made of several parts of the pipe.

to make note taking a smooth knee with a cut-off at the lower end of the oblique.

Mount rainwater heads and downpipes by means of eaves and wall brackets with pins.Fastening strips intended for fixing the funnel cornice pin buckled and shortened so that the inlet funnel cone was located 7-10 mm below the drip eaves and funnel glass bead stiffness relied on a collar pin.

upper wall mount pin is carried out just below the upper transition knee and the bottom - just above noted.Therebetween set at regular intervals if necessary additional pins.Pins attach to clog the holes flush with the wall of birch traffic.

Special skills and experience working with serrated iron does not require, therefore, are new to this business can get out of it high-quality products.This requires ornament or a picture and a minimum set of tools that includes a hammer, metal shears, marking gauge, square, ruler and few sechek.For marking gauge metal work is done in the form of a plate made of hardened steel.The tool has cutouts on both edges.With the help of the gauge draws a parallel to the edges of the leaf marking line.

broken rice should be of three types: semi-circular, round and straight.Round Chaff is made of having the required diameter hardened alloy steel tube.Their working part has good sharpening, and on top is a stub designed to strike it with a hammer.These chaff there serving for removal of material fragments hole.Chaff produced 150-180 mm.

sliced ​​semi-circular shape may have different cross-section: sloping, steep or secondary.Working side to sharpen the width of 3,5-30 mm.You can make a tool and at home.For this purpose a conventional chisel remove the working part, and then give it back a semicircular shape with emery wheel.At the edge of the same circle of the tool perform the work, which was later sharpened.

Direct chaff can be simple with a chisel working edge width of 8 to 30 mm and a taper angle - from 35 to 40 °.

Any necessary tools, including broken rice, can be made independently of ownership, provided the heat treatment skills become.

Usually for this kind of work takes a black or galvanized iron roof.It is preferable to use a black iron, as it more clearly distinguished after staining pattern, blackening.However, this type of iron there is a disadvantage which consists in the fact that it, in contrast to galvanized iron, quickly rust.

run on galvanized iron grooved pattern begins to "play" on the background of brick walls, as well as if the walls of the house and the roof painted in dark colors.

Installation of drainage pipes with his hands

Before you begin any of the work, you must carefully prepare the workplace.To do this, find a beech or oak block of wood and put it on a stable bench.Iron prosekayut should be on top of the block of wood.

tinsmith sits on the bench top so that the block of wood placed between the legs.On one level, with the right block of wood set box of small size, and the left - a table.The table is designed for the storage of tools, and the goats are needed for horizontal arrangement of long sheets of grooved thread.To do

provided prefabricated patterned holes, first on the surface do prosekayut markup using polygon, line, and other instruments, then put a sheet on a block of wood, and all the holes punched chaff, striking them with a hammer.

most difficult parts of the U-shaped punched chaff.The figure at the edges of the pattern is cut with scissors for metal, and the inside - in direct chaff.

for punching small holes, in addition to the listed instruments may need a check.

expanded iron trim by its oxidation, ie blackening.

Held blackening with heating in an enamel pot.However, it is important to note that quite a tight black grooved sheets having larger dimensions.

before blackening previously prepared iron: it is removed from the rust and scale in the following solutions:

1) formalin - 2 pieces;

a 20% hydrochloric acid - 48 pieces;

2) methenamine - 0.5 tablets;A 20% hydrochloric acid - 0.5 liters;

3) hydrochloric acid - 25 pieces;sulfuric acid - 15 parts;methenamine - 0.06 parts;

water - 200 parts.
