Do It Yourself / / December 19, 2019
How cool evening sit by the fire, the flame fry snacks and just look at the fire. Of course, I want to fireplace was not only safe, but also beautiful. And you can make a place on their own. We'll have to leave the building materials store a few thousand, and to work on his plot of about four days. As a result, you will have a great place for a fire that can not only be used for its intended purpose, but also make it a point of pride.
This is the place you can build a campfire in a single weekend and then not zaparivatsya with a place for a campfire. It is simple, but time-consuming process, and all its parts must be carried out carefully, as carelessness can result in unpleasant consequences.
When exposed to a large amount of heat from the fire inside the concrete moisture may expand and cause it to malfunction or even explosion of the concrete structure.
Inside is a place for a campfire can be laid firebrick, that he took away most of the heat.
For the barbecue, you will need:
- Dry concrete mix (40 kg bag). Dilute the mixture with water, dry, and a ready concrete, no way inferior to the factory. You will need about 19 bags of such a mixture.
- firebricks. Bricks will protect concrete from cracking.
- grout. You can mix your own solution, such as clay. This will require one part of clay, 0.2 parts of cement and 3 parts sand and 5.
- reinforcing bar. Reinforcing rods with a diameter of 9 mm for a frame that will support the different layers of concrete. Need for vertical stacking rods 45 cm long, while for the horizontal - 91 cm.
- Gravel. You will need it for the first layer, which will be a concrete fireplace.
- lava stone. On the Internet selling lava stone grill. They will cover the gravel in place for the fire, and that they will make a fire. Volcanic rocks heat-resistant, they are not cracked or destroyed by heat.
- Planed boards size of 50 × 100 × 50 mm and 150 mm for the wooden formwork. They need you to create forms for pouring concrete.
- L-shaped fixing bracket for fastening the formwork corners.
Tools:
- Cordless Drill.
- A circular saw.
You can see detailed instructions for the manufacture of concrete space for a bonfire on the video or read the step by step guide below.
Step 1. We are doing formwork
The outer frame shape is 110 cm length of the four panels. Each panel is assembled from two boards measuring 50 × 100 mm, and two boards measuring 50 × 150 mm. Mark up the desired distance to the tree and cut it in a circular saw.
Step 2. Putting board
To collect the boards together, need boards 50 × 100 mm and 40 cm in length. Using these boards, screws and 6.5 cm long screwdriver you join the board panel together.
Four panels are connected in a square via L-shaped mounting brackets and screws.
Step 3. Making the inner frame
The inner frame is made of two panels 60 cm long and two panels 50 cm long. When you connect the panel box, make sure that the L-shaped brackets and cross boards, fastening panel, located on the inside of the box, otherwise they will be buried in concrete.
Step 4. note the border
Place the outer frame in the desired location of your site, and mark on the ground of its perimeter, adding to it about 15 cm.
Step 5. Digging
Dig marked plot to a depth of about 20 cm. Smooth out the land at the excavated site.
Step 6. filled with gravel
Spread evenly over the excavated gravel ground. The layer of gravel above the ground should be approximately 10 cm.
Step 7. put the form
Place the finished wooden forms on the gravel, measure the distance between the inner and outer shapes on all sides to make sure that the interior is exactly in the middle.
Step 8. We fix form
If the forms are properly installed, you need to fix them by screwing screws two boards. Measure the level of all aspects of the formwork, if some of them will deviate from a straight line, use a hammer to align them.
Step 9. stuck valves
Knock three reinforcement bars on each side. The valve must pass through a layer of gravel into the ground and firmly be fixed there. Further horizontal reinforcement lay, and seal it from the vertical by a metal wire.
Step 10. Pour the first layer of concrete
The first concrete layer should be about 10 cm. If you do not have the construction of the mixer, mix the concrete in a wheelbarrow or another free container and gradually fill the formwork.
Before you can put the fire bricks, wait at least 20 hours.
Step 11. Laying bricks
When that time will pass, it will be possible to lay the bricks. Mix concrete and clay mortar, cover the resulting substance inside of the casing and the bricks and place them close to each other, that they are well kept.
Step 12. More concrete
Next, it's time to pour more concrete about 12 cm. Basically, if you have a mixer, you can mix and pour the rest of the concrete, but if not, it is better to do it gradually, because the mix it is very tiring.
After pouring the next layer of concrete, you can insert more reinforcing bars - two on each side of the vertical. This will help to more securely fasten all layers of concrete. We are waiting for another 20 hours.
Step 13. The final layer
Before you pour the final layer, you unscrew the wooden planks, locks - now they are no longer needed.
Next, concrete fill all the corners of the formwork, "pushing" of his shovel, and sealing by a metal rod, for example a segment fittings or pipes, by shtykovaniya - frequent and rapid concrete piercing rod and make it horizontal and vertical vibrations.
Step 14. alignment
After filling and sealing is necessary to align the top with a spatula design.
Step 15. The final alignment
When the concrete has set firmly (30 minutes after pouring), it is necessary once again to level the surface. After another hour, repeat the alignment, try to make the surface as flat and smooth.
Step 16. Wetting and harboring
After aligning the need to hide the concrete film or burlap. In dry hot weather is necessary to periodically wet the concrete for 48 hours.
Step 17. remove the form
The outer shape is removed easily - enough to roll out the screws and remove the L-shaped bracket. Take the internal form is not so simple. It will have more time to use a circular saw and a hammer.
Once you pull out both forms, the concrete form of rinse from the hose.
Step 18. lava stones
Sprinkle the bottom of the lava stones, which will be a heat-resistant surface for a campfire. Layer stones must rise above the gravel 8-9 cm.
Step 19. Before you arrange a huge fire
It is best to wait about a month before you light the fire inside the finished barbecue - campfire pit. In addition, the first three months it is better not to kindle huge fires that will burn all night, it is better not to burn them more than two hours.
Concrete takes a long time enough to dry completely, and within the finished structure may remain water, which in the case of expansion can cause a crack. So have patience and the first time relight the fire with caution.
That's all you have on the site there is a beautiful and, best of all, made their own hands campfire.
