BBQ oven with own hands

Like to cook shish kebabs and other food in the open air, but still do not have your own barbecue? We suggest that you correct the situation right now! Having studied the following instruction, you will learn in what order the full-fledged garden oven is laid out, and the presented schemes will help you to thoroughly understand all the nuances of technology.

Materials for the construction of a street oven

Name	Average density, kg / m3	Porosity,%	Brand frost resistance	Coefficient. Thermal conductivity, W / m * With	Strength grade	Color
Full bodied brick	1600-1900	8	15-50	0,6-0,7	75-300	red
Bricks with chamotte	1700-1900	8	15-50	0,6	75-250	from light yellow to dark red

Start by preparing the materials. You will need:

• concrete. You do not need much, so you can cook on your own;
• boards for construction of formwork. Excellent unedged board;
• fittings. Needed to harden the foundation. You can use unnecessary metal products - trimming channels, thick wire, strips of steel, etc.;
• edged boards. From such boards you will build a formwork for a concrete screed under the countertop;
• bricks. It will require simple ceramic and refractory products;
• an iron pipe with a diameter of about 150 mm;
• material for waterproofing the foundation. Usually used ruberoid;
• mixer;
• sink. For a garden oven, a metal sink is best suited;
• rubber hose.

Select the required amount of raw materials in accordance with the chosen dimensions of the future furnace.

Recommendations for drafting

Prepare the furnace design. This guide discusses the process of erecting a complete cooking complex, complete with a cutting top and a sink. If the sink and the table are not needed for you, simply exclude from the instruction the stages associated with their arrangement.

Choose the right place for a barbecue. First of all, you should be comfortable to use the oven.

oven Important! If there are tall trees near the selected site, make sure that their branches are not in close proximity to the future chimney. Otherwise, cut the branches, otherwise they will burn.

The furnace should not be adjacent to its rear wall to any structures. During the operation of the barbecue, the brick will be very warmed up, which will not affect the state of the adjacent buildings in the best way - they can simply burn out.

Below are diagrams showing the overall dimensions. You can take them as a basis, but parameter A is better to increase to 1.5 m.

Foundation of a BBQ oven

Furnace will have a relatively small mass. It perfectly withstand a reinforced foundation with a thickness of about 20 cm. For casting, M100 concrete is the best choice.

The first step. Mark the platform under the foundation. Do this with the help of pegs( metal bars, pipe cuttings) and twine( cord, rope, etc.).

The second step. Dig the excavation along the perimeter of the basement. The recommended depth is about 30-35 cm. Be sure to make a 5-centimeter margin along the width of the pit.

The third step. Fill the bottom of the groove with a sand-gravel mixture and carefully compact it.

The fourth step. Make the formwork. In order to be more convenient, preliminarily collect boards of width 30-35 cm from the boards. Select the length according to the dimensions of the sides of the base. Set the formwork elements along the perimeter of the excavation.

The fifth step. Place the reinforcement in the formwork. It is best to use steel bars with a diameter of 1 cm.

The sixth step. Fill the concrete.

It is possible to start further work 3-4 days after the foundation is poured.

Furnace laying

Lay a double layer of roofing material on the foundation. He will assume the functions of waterproofing and ensure reliable protection of the walls of the garden oven from moisture from the ground.

Choose the shape of the barbecue openings. If you want to make rectangular openings, select the material for the arrangement of jumpers. An iron corner will do. If the opening is made in the form of an arch, make a template for laying out the arch in advance. Use a whiteboard to make a template.

Having worked out the above nuances, proceed with masonry work. The kind of bricks, patterns, all kinds of inserts and other decorative solutions remain at your discretion. In this manual, the oven is laid out in a style similar to the design of the house.

Lay out the lower tier. Lay a wall masonry in half a brick, not forgetting to leave openings. For cementing bricks, use cement mortar. Lay out walls of 60-cm height if you plan to build an archway, or to a height of 80 cm, in case you decide to make a rectangular opening.

With this height of the opening and a pair of rows of bricks on top the worktop will be a meter distance from the base, which is the most convenient option for work. If your growth is significantly different from the average indicators, adjust the height of the table to your needs.

If you decide to make a rectangular opening, put a metal corner on the last row of masonry in accordance with the scheme, and then lay the walls of the oven around the perimeter. If you want to arrange the opening of the arch form, pre-set the template for laying the vault.

If a wash is to be installed, at the same stage, place a pipe in the furnace wall. Through it you let the water pipe run.

Lay the walls to the desired height. In the example considered, the height of the walls is 0.9 m. Make the upper row of the masonry with a slight protrusion outward. Due to this a step is formed inside, which allows to install the formwork for pouring the screed.

In order for the masonry to be successful, carry it out with the following rules:

• the seams should be of equal width;
• the height of the openings should be such that between their upper edges and the table there are at least 2 rows of masonry;
• aperture of an arch form is necessary to issue with one central brick.

Having completed the arrangement of the lower tier, prepare the basis for the furnace and the table. Make a screed. Formwork for concrete, put on a previously built step inside the furnace. Cut the boards according to the dimensions of the span. If a sink is installed, leave space in the concrete screed to accommodate it. This is done very simply. You just need not lay a site for installing a sink. Cover it with another kind of formwork, fixed with spacers.

Fill the screed and leave it for three days. After the specified time, dismantle the shell for the shell.

Coat the countertop material to your taste. For example, one-piece marble slabs are wonderful - it is both beautiful and comfortable.

Second tier of the furnaceThe barbecue consists of a fire compartment and walls that close the plot from curious views from the street. With partitions everything is extremely simple - these are ordinary solid walls, laid out in half of the brick. If you want, you can completely abandon their arrangement. The order of construction of the furnace deserves special attention.

Furnishing of the

Furnace The furnace top has a two-row structure: the outer row is laid out of ordinary ceramic bricks, the inner one is made of refractory material.

Put the firebox in the standard way. The recommended parameters are as follows:

The height of the furnace opening is 7 rows plus an arch or 9 rows in case of arrangement of a rectangular opening;

• depth of the furnace - about 600 mm;
• width is about 700 mm.

After laying the opening of the combustion chamber, finish building a couple of additional rows of masonry on top and proceed to the arrangement of the smoke pipe.

To switch to the required chimney width, consistently reduce the length of the walls of the furnace compartment. The back and front edges should be shortened to half a brick in each following row. The lateral walls should be reduced by 25% of the width of the brick. According to this scheme, you need to lay out about 7 rows. Then you can start to arrange the smoke extraction pipe. It must have a rectangular shape. The recommended height of the construction is 12-14 rows.

At this fireplace is ready. In order to avoid any problems during the implementation of this phase, observe the following recommendations:

• do not make the furnace opening too high. It is enough 7-9 rows. Otherwise, the draft in the chimney will become too weak, as a result of which all the smoke will go to the site, and not to the sky;
• the inside of the furnace must be laid out with a flame-resistant brick. Otherwise, the masonry simply cracked under the influence of temperature changes;The
• chimney must not be too high, either.because of this, traction will deteriorate;
• check that the bottom of the furnace compartment is as level as possible - so it will be much easier for you to clean out the ash in the future.

Latest strokes

furnaces Barbeque is almost ready. In conclusion, do the following:

• install mixer and washer;
• supply hoses for water supply and extraction;
• cover the countertop with the finishing material( optional).The best option for finishing is natural stone;
• lay out the area in front of the oven paving slab.

If you want, set next to the barbecue table and a couple of benches. In addition, in such a situation it is recommended to think over the arrangement of the canopy.

Now you know how to build a barbecue oven. The presented unit will allow you not only to cook delicious dishes, but also to burn leaves and other small garbage - the barbecue copes with all tasks perfectly.

The worktop and sink make the oven as user-friendly as possible. You do not have to run into the house to prepare food - everything can be done in one place.

Free space under the table is suitable for storing firewood. Here they will always remain dry and well ventilated, which will prevent the wood from dampening and rotting.

Good work!
