How to calculate the dimensions of barbecues made of different types of bricks

Before you start building a barbecue oven with your own hands, you need to decide on size of the structureOn this basis, a drawing is made, the necessary calculations are made quantities of materials.

The functionality of the oven, the possibilities for its compact placement in already constructed buildings, the cost, and the construction time depend on the dimensions of the brick barbecue oven.

It is enough to determine the pros and cons of barbecue ovens of different sizes to understand whether it suits your needs. The nuances of selection and construction are described below conventional oven And furnace complex, as well as methods of delivering the necessary building materials to the site.

Sizes and types of brick barbecues using three projects as examples

The most popular barbecue oven options are the following:

• simple oven;
• barbecue oven with hob;
• a stove complex with a stove and a work area.

The simplest barbecue oven is created without the use of special construction skills, using ordinary masonry. Such a stove will have a height of 13 rows, 702 mm high, depending on the thickness of the seam. The length and width of the structure are 1810*900 mm.

These are the standard dimensions of a brick barbecue of this type.

BBQ oven with hob will allow you to cook food in the summer. To build such a structure, you will need some stove building skills and knowledge of the principle dutch masonry (when it is not necessary to tie the seams in the rows). Dimensions of the barbecue oven with the stove complex (in mm): depth - 1778, width - 434, height - 1900.

Stove complexes are built by professional stove makers, but simple barbecue projects with a stove and a work area can be tried to be built independently. Dimensions of such a complex (in mm): depth - 1210, width - 2240, height - 1900.

Estimates of materials for the above options

Now that we have determined the most common sizes and types of brick barbecues, let's start calculating the cost of building one type or another. The larger the oven, the more materials it requires and the more expensive it is. The final estimate is also affected by the amount of additional materials, their manufacturer and cost.

Let's look at estimates for typical barbecue options.

If you decide to build mini brick bbq with your own hands, then you will need:

• Solid ceramic brick M200;

Using the drawing, we will produce Calculation of the required number of bricks (by rows): 16+16+16+16+16+45+10+10+10+29+10+10+10 = 214 pcs.

• Varnish KO-85 (reduces water absorption, which allows to extend the service life of a simple barbecue oven) - 1 pc.;
• Board 25 x 250 x 6000 mm — 1 pc.;
• Reinforcement mesh 150 x 150x5 — 2 l;
• Cement — 150 kg;
• Grill grate 390 x 560 x 8 mm — 1 piece;
• Wooden flooring— 2.25 sq. m.

For barbecue ovens with hob You will need the following materials:

• Solid ceramic brick M200;

Calculation of the amount of bricks required according to the drawing: 49+49+32.5+33+34+34+39+30+42+40.5+44+27+27+27+27.5+26+36+27+37+26+28+25+26.5+39+36.5+28+31=901.5 pcs.

• Cement — 150 kg;
• Board 25 x 250 x 6000 mm (for erecting formwork) - 1 pc.;
• Metal waste to strengthen the foundation;
• Cast iron plate 410*410 mm;
• Blower door — 1 pc.;
• Steel sheet 5 mm — 2 pcs.;
• Corner under jumpers - 4 pcs.;
• Rod 230 mm — 1 pc.;
• Grate — 1 pc.;
• Firebox door — 1 pc.

For the simplest option stove complex with a stove and a work area you will need:

• Project for the construction of the complex - 1 piece;
• Red brick — 885 pcs.;
• Fireclay brick — 14 pcs.;
• Cement — 300 kg;
• Formwork board — 1 pc.;
• Table top — 1 pc.;
• Washing — 1 pc.;
• Steel sheets — 5 pcs.
• Blower door — 1 pc.;
• Firebox door — 1 pc.;
• Doors made of metal for cutting table - 1 pc.;
• Metal waste to strengthen the foundation;
• Corner for lintels — 4 pcs.;
• roofing felt — 2 m.

To implement such a project, you will need fewer bricks than for the previous one. But there are more complex and large-sized complexes, for the construction of which you may need 2 or even 3 times more bricks.

Use the above data as an example for your own calculations. Take your project and substitute your barbecue dimensions into the given diagrams: the drawings you will work with must contain this data.

Transportation of building materials to the site

Before purchasing and moving building materials to your site, you need to decide on their placement. Usually, they are guided by the convenience of unloading and further use. It is desirable make purchases in winter, when some manufacturers reduce prices to increase popularity and get rid of overstock.

Regardless of the type of furnace, transportation of materials can be carried out in 2 ways: delivery And self pickup. For large volumes of materials, it is better to order delivery, for the rest - pick up yourself. Ideally, if all building materials are purchased at one construction base - then one car will be enough for delivery.

Features of foundation construction

Each type of furnace has its own peculiarities in the construction of the foundation, which should be taken into account to extend the service life of the furnace.

For a simple stove, the foundation is poured 50 cm more, than the dimensions of the stove in all directions. As a covering, paving slabs, paving stones, etc. can be chosen.

If the foundation is made of slabs, it must be reinforced with a rod and tied with wire or plastic clamps. The foundation setting time is 1 week at an average temperature above 20°C and 2 weeks at a temperature of 17°C and below.

Since the barbecue oven with the stove is larger in size than the previous structure, it needs to be provided with uniform shrinkage using a reinforced strip foundation with a connection between the grill and the stove. Minimum 10 cm of foundation should protrude above the surface.

When the concrete hardens, the turf inside the foundation is removed and the openings are filled with a solution of sand, gravel and clay. in a week The tape is covered with a two-layer roofing felt to prevent moisture from getting in and they begin laying.

When constructing a furnace complex, they do concrete foundation, and if there is no possibility, they put it foam blocks. Depending on the size, the weight of the furnace complex can reach several tons. To pour a reliable foundation for such a structure, you need to dig a trench minimum depth 50 cm and produce reinforcement.

A layer of sand and gravel is poured onto the bottom of the pit and compacted. Afterwards, wooden formwork is installed along the walls and the pit is filled with cement mortar. Metal mesh or steel rods are used for reinforcement. The curing time of the foundation for the furnace complex is minimum 4 weeks.

Construction time

The time it takes to build each type of barbecue oven depends mainly on the drying time of the foundation. For the first two options (a simple oven and a barbecue with a stove) 1 week is enough, after which the finished oven is erected and decorated in 1-2 daysThe curing time of the foundation for the furnace complex is 4 weeks, and the construction of the furnace takes 1-2 days.

Barbecue location on the site

A simple oven is compact, so it can be placed anywhere on the site. There is no table or cutting place for vegetables nearby, which means that everything will be brought to the oven ready for frying. You can place the oven under the kitchen window so that it is not far to carry food and throw lighting with a portable one directly from the house. The fire from a simple barbecue is small, but it is better to place the structure away from flammable substances.

The barbecue oven with a hob should be protected from the wind and stand away from the neighboring area. The area where the barbecue with a hob will stand should be made taking into account a safe distance from the fire during cooking.

The barbecue complex with a stove and a work area should be located several meters away from other buildings to avoid a fire. The back wall will get very hot - and children or animals can hurt themselves by getting too close. Therefore, it is better to build a large complex with its back to an impassable area or to build an additional alpine slide.

Barbecue oven in the gazebo - how to arrange a popular solution

If the stove complex is to be located in a gazebo, it is advisable to make a single foundation. Since a gazebo does not need a foundation one and a half meters deep, it is made smaller. The pipe must be brought out to the street.

Fire safety

You should think about fire safety before you start planning the barbecue area. All structures on the site should be at a distance of at least 5 m from the future barbecue. Flammable items should be removed at a distance of 2 m from fire. Anything that could catch fire if hit by a spark should be removed. at a distance of 10 m from the brazier. Smoke should not reach the neighboring area.

Remember that sparks often rise with warm air - this can cause tree crowns to catch fire. Therefore, it is better not to build a barbecue under trees, but if it is already there, you should trim the lower branches.

If the barbecue is being built in the city:

• place 10 l capacity, filled with water, or fire extinguisher near the place of preparation;
• do not light a fire at a height more than half a meter;
• use charcoal;
• Do not use the grill if the wind speed is exceeds 10 m/s;

Conclusion

The size of the stove should be chosen based on the physical possibility of building it, its purpose. For small gatherings in a company once a month is enough simple oven. BBQ with hob will do if you plan to live on the site permanently in the summer or if you plan to have a lot of guests. If you are sure that you have settled in one place for a long time, you can build barbecue oven complex with stove and work areaThe design is also ideal for the needs of legal entities for holding various events.
