Smokestack on the chimney itself

The smoke extraction system is important for efficient stove operation. The open chimney pipe allows the sediment to flow in unhindered, foreign objects brought by the wind can get into it. All this violates the traction and requires the obligatory cleaning of the chimney. To avoid unnecessary problems, the top of the pipe is covered with a special device, called a chimney or head. Making a chimney with a chimney with your own hands is quite a possible task - this is one of the simplest in construction parts in the exhaust system for combustion products.

Purpose

1. A cap on a brick pipe protects it from moisture and freezing, which quickly destroys the upper edge of the building.
2. Properly designed tip enhances cravings.
3. Smoke box protects the pipe from bird nests and other debris.
4. The original cap serves as a decorative element of the roof design.

Materials for the manufacture of cap

The smoke box is installed in an inaccessible place and operated in difficult conditions, therefore, for a long and reliable service of the device, you must select the appropriate material. The most affordable and practical option is the manufacture of a galvanized steel chimney. Such a product will last at least 10 years. Three times longer your pipe will be protected by a stainless steel cap, and the construction of copper will serve more than one generation. The latter material has a high cost, therefore, when making a chimney made of copper, it is necessary to take into account that the mount must be of the same metal.

The polymer coating of steel extends the service life and improves the appearance of the tip.

Kinds

A standard chimney is a metal structure, the base of which is made in the shape and size of a chimney, and the upper part is a roof that protects from precipitation. One of the most important functions of the chimney is to protect the area around the pipe from sparks and fire. Practical qualities of abstraction of moisture and the obstacle to the entry of birds into the pipe, combined with decorative design. The upper part of the pipe, made in the form of an original design, is a decoration of the house. Protective caps on the pipe differ not only in the material and structural additions - it can be a forged weather vane, a grill protecting the space between the base of the chimney and its roof from bird nests, a hinged lid for cleaning the chimney. The roof of the structure differs in a variety of forms:

• vaulted;
• gable;
• gable;
• chetyrehskatnaya;
• happy birthday;
• spire-like.

One of the types of protective cap is a wind vane or deflector, with circular protection from the blowing wind. Wind gusts falling into an unprotected tip, reduce traction in the chimney. The device on the pipe acts on the aerodynamic principle, it changes the vector of the moving air and increases the efficiency of the chimney. Flyugarka consists of the lower cylinder, the upper glass in the form of a truncated cone and cap that protects the structure. The deflector has two channels for the exit of smoke - the lower annular channel between the cylinders and the upper, which ends the design. Depending on which side the wind blows, the products of combustion are discharged through one of them. The device is made of galvanized steel, capable of serving for a long time in aggressive operating conditions. The diffuser is attached to the lower cylinder with a clamp. The umbrella-cap is installed on the diffuser using brackets.

Manufacturing

Having chosen the material and design of the head, we will figure out how to make it with your own hands. For self-manufacturing, a gable roof with a duo-pitch roof to a square or rectangular pipe is suitable. The work will require the following tools and materials:

1. Scissors for metal.
2. Perforator.
3. Roulette.
4. Vice.
5. Sheet metal for the roof.
6. 4 pieces of a profile pipe 20? 20 mm.
7. Metal corner.

The first stage is to measure the opening of the pipe so that the finished product is securely worn on it, add 5 mm to the dimensions. In accordance with the size of the base is welded for the chimney of 4 pieces of metal angle. At the corners of the welded rack length of 50 cm, they will support the roof. The size of the racks and corners for the base is the same - 20 × 20 mm. The supports for the cap are welded not at the edge, but at a height of 20 cm, their lower part will sink into the pipe about three bricks for better fixation of the structure. The upper part of a length of 30 cm will serve to fix the roof. The steel sheet for the roof of the chimney, cut out in a ratio of 2 × 3, bends in a vice at a 90 degree angle and forms two slopes. This cap will be attached to the racks with plates and rivets. Two holes for fasteners are drilled in each of the four metal plates 20 mm wide. They are applied to the roof blank and tags are transferred to it. For these marks in the metal cap punched holes for rivets.

All parts of the base are coated with a primer, and then with a special paint for metal. The roof is treated in the same way and painted in the color of the base. The mounting plates are welded to the posts at an angle. They put on the roof and after aligning the holes fixed with rivets. Finished chimney set on the pipe and secured with anchors. The design requires reliable fixation so that it does not get blown away.

A simple model of the chimney can make anyone who knows how to use the tool. With a protective cap, the heating system will work more efficiently. For a stylish design, the design is decorated with wrought iron elements.
