brief information

Fencing (fence) slabs PO 2- these reinforced concrete products are rectangular slabs, the purpose of which is to fencing construction sites, warehouse areas and other protected objects. Fences made from such prefabricated elements provide the possibility of reliable fencing personal plots, cottage villages and gardens. PO 2 fencing slabs have a number of advantages, one of which is providing certain sound insulation and protection from dust. There is also the possibility of painting the product to give the product a more aesthetically attractive appearance; any paint can be used for coloring since the surface of the product is quite susceptible to dyes. Fencing slabs have a high degree of reliability, installation is quite simple and quick, and they have the function of protecting property or territory from intruders, vandals or uninvited guests. The slabs are available in two configurations - with and without legs; a special glass is provided for each product for reliable support and fixation of the slabs.

Iron concrete plates PO 2 fencing is a highly durable product; due to its characteristics, the slabs perform their main functions for quite a long time. These concrete products can withstand a number of unfavorable factors, such as the influence of aggressive environment And climatic conditions. Additionally, installation on the upper edge of the slabs is possible barbed wire to prevent intruders from entering the territory. The slabs weigh about 1.5-2 tons, so installation is impossible using special equipment. Installation of fencing slabs is carried out along the perimeter of the strategic object in concrete cups intended for installation. The base of the slabs is quite stable and dense, which is why laying a special foundation is not required.

All reinforced concrete fencing slabs PO 2 are absolutely identical, therefore, the slabs are interchangeable and complementary. Today, a fence made of reinforced concrete slabs is the simplest and most reliable way to fence and protect an area. In terms of strength and durability, a fence made of reinforced concrete slabs can only be compared with a fence made of natural stone. Brick fence in all respects it is inferior to its reinforced concrete counterpart since it is most susceptible to deformation, there are difficulties in construction, and high cost. In some cases, various corrugations or patterns are applied to the slabs in order to distribute wind loads and make gray concrete more modern. Quite often, the relief of fence slabs is deliberately made quite voluminous to avoid the possibility of climbing along it. The large mass of the slab does not allow it to be moved by either wind, moisture or humans. Lifting of such massive concrete panels is carried out only with the help of a crane with a uniform load on all steel mounting loops.

Production

Reinforced concrete fencing slabs PO 2 are made of heavy concrete, class not lower than B20, using vibration pressing or vibration casting.

Cement and sand are used to produce a quality product High Quality Thus, the slabs gain strength, reliability and durability. Fence slabs are reinforced with steel of class A-III and BP-I, welded into frames. The fittings are necessarily treated with special anti-corrosion compounds.

Installation

The construction of reinforced concrete slabs PO 2 is quite simple. During installation, no special foundation is required. The technology for assembling reinforced concrete fencing panels consists of several stages. The first stage is installing the base for the fence on a previously prepared area. This base is massive concrete blocks, which have the shape of a truncated pyramid - “glasses”.

Next, The final stage, - installation of the reinforced concrete slabs themselves. The already installed support blocks have specially designed slots or “grooves” on both sides, into which the slabs are inserted using a crane and several workers who guide the slabs. When installing a structure made of reinforced concrete slabs temporarily, for example on construction sites, wooden wedges are driven between the glass and the slab for reliable fixation. If structures made from fencing slabs are erected as a permanent structure, concrete is poured between the slabs into a glass, which firmly fixes the slab. Various design features slabs allow you to connect them into a single continuous fence wall. These products are reusable elements, since after dismantling they can be used in any other place without losing their original qualities, for example, on construction sites, when a building is being erected, iron concrete fence disassembled and transported to another location.

Marking

The symbol of a fence slab consists of alphanumeric designations, which include the designation of the type of structure and standard size. For example, a slab marked PO 2 (2500x 150x 3000 mm) has the following meaning: PO - fencing slab; The number is the standard size of the product.

There are several markings for this type of product:

1PB 40-20 2PB 30-16 P 5 P6 PO 2

Dimensions

The finished slab fence reaches a height of up to 2.9 m. Civil structures and construction sites are fenced with reinforced concrete fences 1.2 and 2 meters high. The use of slabs of exactly this size prevents either people or animals from entering the facility, and also reliably hides the space from prying eyes.

Transportation and storage

Storage and stacking of fence slabs PO 2 is carried out horizontally in stacks. There should be no more than eight panels in a stack of slabs to prevent overloading. Between the slabs, wooden spacers are placed strictly along one vertical line. During the installation of fence slabs, vertical supports are used to prevent the slabs from tipping over.

Floor slab for trays and channels with a hole ( PO 2 ) – a rectangular slab for covering channels, tunnels, thermal chambers made of tray elements at the location of the vertical entrance to the channel. The task of the slab is to overlap the trays at the point where the chamber is formed. For this purpose, the plate design contains one or two holes with a diameter of 700 mm. Floor slabs are placed on trays and chamber beams, and then installed on the slab concrete rings, which make up the chamber shaft.

Also, the presence of the slab helps maintain tightness and protect underground utility channels from destruction of insulation, soil collapses and moisture ingress.

The shape of the PO 2 slab is rectangular flat plate with one or two holes for subsequent installation of inspection wells.

The floor slab is used both in above-ground and underground channels, as well as those laid under iron and highways. The depth of such channels under the soil layer is from 0.5 to 6 meters. This means that the coating slab must withstand sometimes colossal loads. The material that helps the slab carry vertical temporary and long-term loads is heavy concrete B 25 (M200-300) and high-quality steel reinforcement classes A-I and A-III. Reinforcement of the PO 2 floor slab is made with welded mesh and frames made of rod reinforcement and wire, the frame is laid under protective layer concrete 15-20 mm. The presence of holes should not affect the strength of the product, because its task is to protect communications. Therefore, in places where there are holes, additional reinforcement is installed with separate steel rods and meshes.

Issue 6 This series involves the production of floor slabs with a length of 1450 mm, a width of 1500 mm and a height of 120 mm.

The section thickness of the floor slab is 120 mm. The standard sizes of the slabs are determined by the fact that the trays are overlapped by them both along and across, according to the overlap schemes of the chambers and channel units.

Designed for use under scouring influences groundwater The plates are additionally protected from corrosion. For this purpose, special additives are added to the concrete mixture. Thanks to them, the slab can withstand the effects of aggressive chemical environments for a long time. All slab embedded products also have anti-corrosion treatment.

The weight of the PO 2 channel covering slab varies and is 550 kg. Such a cover is tightly fixed to the channel due to its weight, this prevents the subsequent sliding of the slab on the concrete.

The slabs are installed using a loopless installation method using sling holes. Less common are slabs with mounting loops incorporated into their design.

The covers of the channel trays are characterized by increased frost resistance (F300), this allows the slabs to withstand frequent temperature changes characteristic of middle zone Russia. A high class of water resistance together with high-quality waterproofing guarantees the channel dryness.

After welding the brackets, the seams and slings between the tray elements and floor slabs are sealed with mortar or mastic, and the channel is hydro- and vapor-proofed.

Product marking

The floor slab is conventionally designated by an alphanumeric combination. Designate the type of product, serial number by size and calculated equivalent load in tf/m2. If necessary, the resistance of the slab to aggressive environments is designated by the letter N.

As an example of slab marking, consider (1450x 1500x 200 mm), where:

PO – channel floor slab with a hole;
Number – standard size of the product;

Markings, as well as the date of manufacture and weight of the product are located on the end face of the plate.

On acceptance tests control the following parameters of floor slabs:

concrete strength (class of concrete in terms of compressive strength, tempering strength);
compliance of reinforcement and embedded products;
strength of welded joints;
thickness of the protective layer of concrete to the reinforcement;
integrity and purity ventilation ducts;
accuracy of overall dimensions;

The batch of channel covering slabs must be accompanied by technical certificate , in which they indicate:

grade of concrete in terms of strength and its average density;
tempering strength of concrete and actual tempering density of concrete;
concrete grade for frost resistance;
concrete grade for water resistance;
date of manufacture of slabs PO 2.
number of reinforced concrete products;
indication of compliance with the state standard.

Transportation and storage

Coating slabs, unlike most reinforced concrete products, are transported in the “edge” position. Stacked concrete slabs should not be higher than 2.5 meters. Under the bottom row of slabs, on a leveled base, a wooden pad with a thickness of at least 3 cm is placed. The products are transported by various means of transport, securely fastened, using gaskets and pads at the locations of the lifting loops.

Currently, the construction industry is developing by leaps and bounds, and more and more often in cities you can see construction sites on which new buildings are being erected or old buildings are being restored.

This is what a typical fence made from PO-2 panels looks like

These areas must be properly fenced, which forces developers to think about arranging appropriate structures that meet the following requirements:

Due to the fact that construction sites are a source of increased danger, it is necessary that the fence excludes the possibility of causing harm to bystanders;
Stored at construction sites Construction Materials and tools in large quantities, therefore it is necessary to ensure their safety;
Since such fences are temporary, it is necessary to be able to quick installation and dismantling;
In order not to slow down construction, fencing should be available for purchase;
The ability of fences to withstand mechanical stress is very important in construction sites, so the practicality and strength of the fence will be very useful.

An example of an old fence made from PO-3 panels

As a rule, construction sites are fenced or that meet the above requirements. Reinforced concrete fences are more durable and expensive, so when choosing a specific option, the material resources allocated in the estimate for the construction of the fence and the requirements for the safety and reliability of the future fence are taken into account.

Reinforced concrete fences

Let's look at a few of the most popular models reinforced concrete fences which are presented on construction market currently. installed in special glasses. Therefore, than shorter length sections of the fence, the more glasses you will need. On the other hand, reinforced concrete fence sections of shorter length are cheaper.

The conclusion is this: shorter fence models require installation more glasses, which increases labor costs for the construction of the structure.

Model of industrial fencing installed in special cups

However, longer sections, although they allow you to save on installing glasses (their cost, as a rule, is a third of the cost of the stove), are noticeably more expensive.

PO-2

PO-2 fences have the following dimensions: length/height/width - 2.5 m/3 m/0.15 m. This model is the most compact in the line of reinforced concrete fences, which affects its cost. PO-2 fences can be found not only near construction sites; they are also often used to enclose warehouses, large industrial zones suburban areas and even military units and correctional institutions. The price of such slabs averages four and a half thousand rubles.

A variation of this type of fencing, marked PO-2M, is distinguished by the presence of an apron at the bottom, which makes it possible to reduce the distance between the fence and the ground.

The cost of such modernized sections is higher than standard ones.

PO-3

This type of sections reinforced concrete fences differs from the previous one only in length, which is three meters. Accordingly, its cost and weight will also be higher, however, structurally these slabs are no different. Just as in the previous case, this model has a variety - PO-3M.

The apron allows you to increase the safety of the future structure, because it prevents penetration into the territory through the distance between the ground and the fence. In addition, thanks to the apron, it is possible to reduce labor costs for construction, because in this case there is no need to install earth fill or seal the gap in other ways.

Reinforced concrete fences are among the most durable and reliable types of fences. They are used not only for fencing private areas, but also parking lots, closed production facilities, construction sites, and large warehouses.

Features of PO-2

Panel PO-2

Since reinforced concrete structures perfectly perform a protective and fencing function, they can be safely installed in remote areas. PO-2 plate is a heavy reinforced concrete product rectangular shape with ribbed protrusions.

Attention! A concrete fence made of solid slabs is installed in special concrete cups, which are located at a distance of 2.5 m from each other.

In this case, all concrete sections are divided into two types:

with an apron;
without an apron.

Reinforced concrete fence

The former allow you to close the gaps formed between the fence structure and the ground, so that even a small animal will not be able to enter the fenced area. In the photo you can see the standard PO-2 fencing design with a ribbed surface, which was not designed in decorative purposes, but so that the concrete fence can self-clean from dust and rainwater.

A reinforced concrete panel can be mounted on either heaving or bulk soil. Since there is no need to pour a foundation to assemble the fence, the structure can be installed in almost any area.

Production and standard sizes

Markings on the plate allow you to immediately identify the type reinforced concrete structure, as well as her standard size. The PO-2 plate has the following dimensions:

height – 3 m;
thickness – 0.15 m;
length – 2.5 m.

In this case, the letters “PO” mean that we are talking about a fencing slab, and the number “2” means its standard size.

Concrete panels are made from concrete, the class of which cannot be lower than B20. In this case, the method of either vibrocasting or vibrocompression is used. In addition, to obtain a reliable and durable design, during manufacturing concrete mixture, apply only quality sand and cement. Additionally, the fence panel is reinforced with steel rods welded into a solid frame.

Important, that even at the reinforcement stage, all steel parts are coated with anti-corrosion compounds, this allows the slabs not to collapse for many years.

The production of blocks is shown in the video:

It is also worth noting that installing the fence will require special equipment, because one reinforced concrete slab weighs at least 1500 kg. In addition, the safety indicators of the structure can be increased by installing barbed wire on the top of the fence.

In this way, you will protect the fenced area from unauthorized entry, but at the same time, installing a “security” fence will not cost too much.

Product advantages

The reinforced concrete slab cannot boast of high aesthetic indicators, but consumers fell in love with it thanks to its excellent technical qualities, namely:

Durability. Concrete products can last at least 70-80 years;
Frost resistance. Even with very low temperatures the concrete will not crack or begin to crumble;
Low cost. Compared to reinforced concrete sections of other brands, PO-2 is significantly cheaper;
Practicality. Fence slabs do not require constant maintenance, and due to the identity of all sections, ribbed panels are interchangeable;
Speed of installation. To erect a fence, a lift is required, but the whole process does not take much time, since installation does not require laying a foundation or installing additional supports;
Security. Due to the high strength of the material, it is almost impossible to demolish or damage a concrete fence.

Subtleties of section design

Fence section

Obviously, you won’t be able to install a concrete fence yourself, because only one slab weighs at least one and a half tons. For this reason, it is impossible to do without the use of lifting machines. At the stage of erecting a fence, it is very important to ensure that the sections are installed correctly in concrete cups. At the same time, verticality installed slab must be checked using a level.

Moreover, still at the stage preparatory work, you should do the following:

Along the perimeter of the territory where the sections are planned to be installed, eliminate all unevenness on the ground;
If the soil is not dense enough, create sand cushions at the site where the glasses are installed;
Compact the soil well.

Fence diagram

Typically a forklift with a manipulator is used. This special equipment is best suited for installing a fence. If it is not possible to order such a machine, you will have to hire at least two standard units of lifting equipment.

After all, first you need to transport reinforced concrete panels, and then unload them using a lift. Please pay Special attention that when storing sections one on top of another, they must be separated wooden beams so as not to damage the surface of the products.

Results

Concrete fence - durable and durable design, having improved technical indicators. Due to the reliability of reinforced concrete fences, they are installed not only around private houses and cottages, but also in protected areas, as well as closed commercial facilities.

High-strength fence sections do not have a very attractive appearance, but if necessary, they can be painted, which will improve the aesthetic characteristics of the fence.
