Pole for the fence with his hands
Regular readers FORUMHOUSE site is well known that the fence, in addition to protecting functions, is also a decorative element.
Qualitatively made a fence or hedge picturesque become the hallmark of the house and grounds.
We have already talked about, like a vegetable garden with the idea and how to build a reliable fence on the ground, exposed to the forces of frost heave.
Despite its apparent simplicity, the erection of the fence - troublesome and costly. For the pillars of metal pipe can be used under the guard of a country house. Despite the ubiquity and ease of installation, they are not without drawbacks. This material may rust at the exit site of the soil column, and quality thick-walled metal profile is quite expensive.
How to make a concrete pole
One alternative to metal posts can become self-made monolithic concrete. Despite the increased complexity of manufacturing such supports, they have the advantage over the metal:
- Characterized by high strength and a long or a one-year service life;
- They can make any size and cross-sectional shape.
- The concrete column can be at the correct height zamonolitit mortgage elements: anchor loops necessary to secure the web fence, gate and gate;
- Inside it is possible to hold concealed wiring required to connect the motor sliding gates, etc.
Formwork for pillars of the fence with his hands
There are two main technologies for producing concrete pillars:
- Pouring concrete into the formwork at the installation site;
- at the site of manufacture and its subsequent installation on location.
Consider the first method. At first tally reinforcing cage (since concrete has a low flexural strength, and enhances steel structure) of three or four steel bars, which is then lowered into a pre proburonnuyu ground well.
You must then concreted part of the column that is in the earth. Then, when the concrete attains strength, set formwork and topped that part which is above the ground.
Decking can be:
- Circular shape (made of a metal pipe). To concrete is gripped with the walls, they may be a mixture of fluff lubricating oil and diesel fuel;
- Square shape - knocked out of boards. In this case, the board inside lined with dense polyethylene film, "targeting" to the stapler.
The main problem of a monolithic casting post the entire height is the difficulty vibration poured concrete. To properly provibrirovat it, you can use the hammer, working in the "hammer". Or use the so-called method of "shtykovaniya" solution by long fittings.
These methods do not provide 100% assurance that there will be a plurality of shells in a solution containing air, which significantly reduces the strength of the concrete. The solution may be the use of sliding formwork.
Is it so - is taken meter piece of pipe grinder and cut lengthwise into two parts. pipe parts are tightened together by collars screwed.
After the concrete is poured and set them strength formwork is disassembled and rise above - to its lower part a few centimeters covered the top of the column is already cast.
So, step by step, the whole structure is filled to the desired height.
Columns for the fence with their hands.
Despite the complexity and increase the work time (before you fill in the upper part, you must wait until the "grab" the bottom), the method makes it possible to achieve a good quality Vibrating mixture.
Also one of the versions of such filling can be used as an ordinary plastic pipe casing.

- To pour concrete footings for the fence, I took a red PVC pipe of 160 mm diameter. Reinforcing cage - 3 steel rod 10.8 mm in diameter. Borehole diameter of 190 mm I drilled hand drill to a depth of 75-80 cm (depth of soil freezing in my 70 cm). Concrete is poured into the base under the liner of roofing material, coiled in two layers. At the bottom of the well, I made an extension, like a basement TISE a diameter of 22-25 cm. As used backfill sand with gravel fraction 3-15 mm.
The first fence post forumchanin poured sand concrete. Ratio: 3 parts sand to 1 part cement M500, but then he changed the proportions of the mixture, taking M500 1 part cement, two parts sand and 2 parts gravel fraction 3-15 mm. The height from the ground turned 195 cm. According to estimates forumchanin, the cost of this pillar is 200 rubles. Last winter showed that the technique works - nothing is kicked and twisted.

- We're with a friend decided to fence pouring concrete pillars. As used napilenny formwork in size sheet OSB 150x150x2100 mm. And to turned rustication, wedges inside formworks fastened 20x20 mm. Concrete was taken from the factory - M200. Just poured 51 concrete pole. Frankly - from an aesthetic point of view, such designs look much better than metal!
Filling without sliding formwork
Another pillar fill option in place can become a method without using a sliding formwork. In this case, concrete is poured into the finished shape - permanent formwork - asbestos cement pipes. The general scheme of such a casting is as follows:
- Garden borer is a hole in the ground to a depth of soil freezing. At the bottom of the well is an extension for "anchoring" the base.
- inserted ruberoid "shirt", coiled into a cylinder in a well. Diameter "jacket" to be a few centimeters larger than the diameter of the asbestos cement pipe.
- In the well established reinforcement cage. It is set not to the bottom of the well. It is necessary to provide a protective layer between the concrete and the ground reinforcement.
- Ruberoid "shirt" concreted.
- In the "jacket", filled with cement, vertically installed asbestos cement pipes - so that its lower part was in the solution. The pipe is fixed by spacers.
- After the mixture solidifies, asbestos cement pipe concreted up to the top.
Forms for concrete poles for the fence
The second version of the production of concrete pillars - cast into shape and further installation of the finished product in proburonnuyu well. Let us consider how to make the form of columns. To do this on the screws going wooden box the size of a future column. Wall formwork lined with plastic wrap or a plastic obbivat. Also, for such a formwork can use laminated plywood. The box is laid reinforcement cage and filled with concrete. After concreting and pour mixture formwork understands and we get ready to post, which is then set in place.
With this method it is possible to produce shaped pillars, which concrete is poured into a specially molded formwork.
The main drawback of this method is that the manufacture of massive, heavy post, for its installation may require the use of special equipment.

- I've been doing concrete pillars size 100h100h2300 mm below the netting. Triangular reinforcing cage knit and cooked from 3 bars 8th fittings. On formwork edging he took a six-meter tos. I sawed it up and collected boxes are placed on a flat surface and spread a film underneath. In the center of the formwork tightening screwed bar to avoid being rasporlo during concrete pouring, and then poured a solution. Fitting Technology finished structure ingenuous - garden drill hole is drilled with a diameter of 14 cm, put column sinuses is filled with sand rammer binding layerwise by pouring and water.
Experience has shown forumchanin, the pillars of this section are suitable for installation of netting, while for heavier fence You need to increase their size: to make their section 120h120h2500 mm and the reinforcing cage of tie rods 4 10th valves, etc.
No matter which column is taken - a metal or concrete, and its section, respectively, bearing capacity depends on the intended load. It is necessary to take into account the weight of the web fence wind load.
Metal profile has a low weight, but also a large sail. Rabitz, conversely, has a small sail area.
Therefore, to make a concrete pole with your hands, you must take into account all the nuances in advance, then later do not have to engage in costly rework.
