Concreting pillars for fence

erection of a fence around your site and possibly any other permanent or temporary fencing - this is a procedure without which no cost, no suburban construction.And it will be a big mistake to let this issue "on its course », he says, against the background of the scale of the main activities here, everything is solved quickly and easily.

quality, durability, and decorative fencing, particularly indicative of the external border of their own possessions, not less important, than the corresponding characteristics of other buildings.And refer to a device such elements need with no less attention than to the rest.And one of the main problems in this block of issues is the right choice, placement and concreting of the pillars for the fence.

What poles and when it is better to use

A. first of all, will understand ,what requirements must meet poles for the fence:

• Probably, there is no reason to closely engage the fence almost every year.So, bollards must be durable, designed for continuous operation with a minimum required level of care.
• Poles should be free, with the necessary safety margin to withstand the weight and construction of fence spans , and dynamic loads. First , of course, it concerns the impact of the wind, especially on exposed areas.

But even in the quietest corners of the need to take into account a margin of safety to the fence not showered by snow drifts, away from pets (small to large) or even of , that by span or the pillar leaning against some "tired "citizen returning from a party at night.

• Poles have a good host, least , not to spoil the appearance of the house guards.They need to fit well into the overall composition of the fence, gate, gate.Sometimes - even more precisely poles and set the tone for the whole ensemble of the territory fences site.

If the columns appearance can spoil your overall picture, means they need to make the invisible prying eyes.

B. second aspect.Installation Technology fence columns depends on the material of manufacture.Well, this parameter is directly related to the type of fence.That is to say, "you need to dance on the stove» - start with what we need the fence in the area.

So, in modern building practice most often used the following types of poles for the fence: wood, asbestos cement, concrete, metal, built of bricks or other building blocks.Each type has its advantages and disadvantages.For convenience - these are summarized in the proposed attention table:

manufacturing Material column	Thumbnail	Advantages	Disadvantages
Wooden poles		Very often - the most affordable.	require mandatory processing special structures
often has the opportunity to free manufacturing	Even after treatment did not differ longevity - rarely when will last more than 10 years
Easily attached cross joists and spans the fence
asbestos cement pillars		Low cost, commercially available	Fragility - may crack if accidentally accented beats
Easy to install themselves pillars, practicality	After contact vnurt water may break in the cold requires mandatory sealing top
	There are difficulties with fastening to the posts transverse lag
Concrete poles		Universal - suitable for all tipv fences	large mass that complicates the delivery and installation of pillars
At qualitative execution- the highest durability	These columns can not be considered cost-effective solution
may have an interesting exterior design
Metal poles		complete versatility with all types of fences	there were no significant deficiencies.The only thing you can say about the current high cost of metal rolling
can use any themselves pillars installation methods	requires regular maintenance - staining
It is possible to make extensive use of welded joints, which opens up a lot of options in the construction of fences and gates
With proper treatment of metal - high durability supports
Brick pillars		"champions" for decoration.	probably the most expensive of all.
	require mandatory foundation fill.
	for their construction requires high skills of the mason
	requires specific external treatment and care

And now look at the compatibility of said support columns with different types of fences.

• For wooden fence (fence usual) there are no limitations - the mass of his small, sail also , and you can use absolutely any type of poles.The only question is the appropriateness of such use from an economic point of view and from a visual point compatibility.

True, wooden fences sometimes take sometimes very interesting, sometimes - fanciful shapes that require special approaches.

• Akin to conventional wood in construction and in the parameters - metal picket fences.They - durable than wood, and also can be installed with any types of bars.

Their low weight and the lack of any meaningful sail does not impose specific requirements for the posts.

• Fences made of corrugated metal - one of the most popular in our time.By its total weight of such spans particular load is not given, but they require a solid surface to reflect on the sail design.

where requirements have to be higher - and in relation to the location of step supports, and from the point of view of recessed . But any poles ( true , the use of wood can hardly be considered seriously ) can be used on a large account ,.

• Currently gaining popularity light and seemingly even - almost weightless fences of polycarbonate panels.

to the posts, pillars requirements can be left the same, as a fence of corrugated board.But generally use enough "miniature" bars of profiled steel pipe.

• for fences (temporary or stationary) of chain-link fencing match, in principle, any columns.But as an inexpensive fence itself, it is usually used metal unpretentious, and the mesh itself or enclosed within the scope of the corner , or simply tie to the supports.

be fine and thin concrete casting (according to the type of garden "grape" columns).

• Heavy require treated accordingly.As supports for their stand or concrete pillars, or corresponding steel pipes of large diameter.

to mounting pillars requirements here - increased.But such support can withstand very heavy load with any fence - the only question is whether they should be used with other fences.

• Finally, brick fences.It is clear that even to observe the "completeness" fence, you must use either the brick pillars, posted independently of a suitable material or concrete, which does not spoil the appearance.

However, often use the fact that in the construction as supports are metal profiles, which are subsequently obkladyvayutsya decorative brickwork.

Practically any "scenario" brick worries demand around the perimeter of the tape base.

Now that clarified the relation "fence - posts", you can proceed to install technology supports for the fence.

Is it always justified concreting?

interesting twist!Article about concreting pillars, and immediately categorical question - whether it is necessary at all?

The thing is that sometimes the specific conditions of the construction process of concreting do either absolutely impossible or impractical.The main reason for this - especially ground layers at the site.

The fact is that if the soil on the territory of wetlands with high water location layers , the inevitable effect of the winter swelling.

located Close to the surface of the water when it freezes, expands, literally pushes on the surface of all structures, concrete zone which is above the level of soil freezing.

get the picture, as if under legs subsided land itself.In fact the same - this is a clear sign that the winter-peaking just pushed a seemingly good faith made the pillars on the surface.Naturally, such a process can take place irregularly and means fence warp, spans deformed.

Popping established pillars of the soil under such circumstances depends on the strength of the application area at the bottom.So in this case we can talk about, is the concrete belt around the pole plays a completely opposite role - he does not improve the stability of the support, but only significantly reduces its .And it is wider than the diameter at the surface, the more evident this negative effect.

Conclusion - not always concreting pillars can solve the problem of the construction of the fence.It would be optimal if the section prevails sandy soil which simply by their structure can not hold poles under load.It is justified in shallow concreting black soil regions - the level of soil freezing it reaches a considerable depth.But if the soil clay (loam), with high location "perched", then you need to install or use a different method, or to apply special concreting practices , with the obligatory depression in the ground below the frost.

In normal practice, a few ways to install poles - this is a common plugging them into the ground, backing (sometimes you can come across the term - dry concreting, although he does not differ correctness of the wording, since concrete in this case general not apply)only partial concreting at the top of the buried plot point concreting of the entire depth, filling the continuous strip foundation for a fence with pillars .

1 - usually by plugging into the ground.

2 - partial concreting - in the upper half of the wells.

3 - complete concreting column.

4 - backing pillar rubble .

Now « stroll » for all these technologies in more detail.

Clogging pillars into the ground

If the site soil "problem", and to the fence, in principle, is not presented too excessive demands, it is possible to confine the easiest way to install.It refers to conventional zakolachivanie pillars into the ground.

probably do not need to emphasize obvious - it possible only when using metal poles - all other columns are simply not withstand the shock load from above.

to install bollards in in se will not do without proburivaniya vertical holes.It usually takes wells and that 50 ÷ 100 mm diameter already planned post, and the depth is approximately ⅔ of the total "immersion".

Hole need for ease the passage of the upper layers of dense , and giving directions column installation.It would seem - simple and reliable , but as usual, there are some significant drawbacks :

first - the operation can not be considered safe - to apply sufficient force need to be above the upper edge of the post slaughter.And at the same time you must ensure that (control) for vertical installation.In a word, no matter how adequate and extremely accurate nor was « zabivalschik » never ruled out the risk that he will not miss with a bang.Sledgehammer must also be such that there was no likelihood of formation flying hammer with handle.

second - this method can taken seriously . probably, only in the construction of temporary or very light fences.Like it or not, but even not too accented efforts will shatter and bars, and a fence on the whole.

«Dry concreting » or butovanie

As already mentioned, the score can only metal supports.But if you plan to install wood, concrete, asbestos-cement pillars, but the concreting is not possible, have to resort to the installation of the rammer.

• No special no secrets here.First of all, after the markup for each column drilled hole with a diameter of about twice as wide.If there is no drill, manual or mechanized, the pit can be dug manually, However, the quality of the subsequent compaction may be affected by this - too wide pit too not needed.

• depth of immersion into the soil is usually calculated so that at least a third pillar was under ground.So, to set the two-meter pole, boring deeper into the ground about a meter.
