Slab of 2 volumes. Support plate PO2. Installation of reinforced concrete fencing

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 slab 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, and in order to concrete fence could 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 structure, during the production of the concrete mixture, only high-quality sand and cement are used. 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 when 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.

Today, construction is on the rise, its pace and scale are growing every day. Therefore, construction firms and companies are faced with one very important question: how and with what to fence construction sites.

But the enclosing elements are subject to quite serious requirements:

• Firstly, ensuring safety.
• Secondly, the safety of building materials, mechanisms and other valuables.
• Thirdly, speed and ease of construction.
• Fourthly, availability of purchase.
• Fifthly, practicality.
• Sixth, strength.

If we consider all modern enclosing elements, we can single out two that exactly fit these requirements. This . The choice of one or the other depends on how much money is allocated according to the estimate for the construction of construction site fences. But let’s not forget that the degree of reliability in this case will play an important role.

Reinforced concrete fences

In this article we will talk specifically about. Therefore, you will have to consider several models that manufacturers offer today. But first we note that the price of the issue often depends on the speed of construction. The point is that the faster the fence is erected, the faster it will be possible to begin the construction of the building itself.

Therefore, concrete glasses are installed under each fence panel, which are placed at a certain distance from each other. The distance is determined by the dimensions of the fence slabs themselves. For example, fence panel 2 has a length of 2.5 meters, and panel p6v has a length of 4.0 meters. Accordingly, the second model reduces the presence of glasses, which can reduce the cost of constructing the enclosing structure.

But it must be noted that this model costs more than the first, so you have to decide what is more profitable in the first place - to reduce labor costs or financial costs. True, very often these two indicators are dependent on each other, and this dependence is direct.

Let's look at some models separately.

PO-2

Dimensions of fence slab PO 2:

• length 2.5 meters,
• height 3.0 meters,
• width 0.15 meters.

This is the most, so to speak, “small” one. Accordingly, its cost is lower than all other models.

But, as practice shows, this structure is very often used not only as a fencing for construction sites. They fence it off industrial facilities, suburban areas large sizes(especially the rear edges), military units, warehouses for various purposes And so on.

I would like to add a subtype of this model, a 2m fence slab, which has an apron in its design. Respectively source material more is spent on this type, which means the cost of this product is higher, as is the specific gravity.

PO-3

The PO 3 fence slab differs from the PO-2 model in its length, which is three meters. Of course, the price and weight of the structure will differ, but in all other respects it is still the same fence slab. This is high strength and reliability, almost endless operation, such a product will withstand any load, both mechanical and natural.

It is also necessary to note the subspecies here - this is the PO-3m with an apron. By the way, about the apron, how does this option differ from the standard one? As shown in the photo above, this is very clearly visible, this design increases the safety indicator, and also reduces the labor costs associated with adding soil under the fencing slabs or sealing the space with bricks.

Currently, this model is very popular (meaning with an apron), it is with its help that you can increase the safety indicator and reduce the financial costs of installation and installation.

Let's start with the fact that it will not be possible to install reinforced concrete fence slabs, so to speak, with your own hands.

It is not only difficult, but also difficult.

• Firstly, the lightest weight of the PO-2 slab is one and a half tons. Even if there are ten of you, it will be impossible to lift it, much less install it correctly in glasses.
• Secondly, it is very important to accurately place the glasses in place and align them in planes. Very often, the soil underneath is leveled and tamped with a sand cushion.
• Thirdly, for this task you will definitely need special equipment in the form of a crane.

Attention!
The best option delivery and installation (for example, of a design such as a PO2m fence) will be a special vehicle with a manipulator.
He will not only deliver the panels to their destination, but will also install them. So to speak, two in one.

If it was not possible to get a machine with a manipulator, you will have to use a double action: bring the slabs on one machine and unload them with a crane. By the way, you will have to store all the products, so prepare wooden linings that will delimit each element separately. Installation instructions are quite simple, but best of all this process pass it on to specialists.

Conclusion on the topic

Reinforced concrete products have always been distinguished by high strength indicators. This is precisely why they are chosen.

It is important to understand here model range, which is mainly responsible for the dimensional characteristics of each product. Therefore, the video in this article will help you. Watch, understand and put into practice.

Purpose:

Fences from reinforced concrete panels are widely used for fencing construction and production sites. The ease of installation and durability of the structure distinguishes a fence made of reinforced concrete panels installed in specially made “glasses” from other types of fencing.

Options:

Reinforced concrete fence s mainly consist of a fencing panel (FP) and a fencing foundation (glass) (FO).
Reinforced concrete fences are made of heavy concrete. Concrete class for compressive strength B15 (M200). For reinforcement, steel of classes AI (A240), AII (A300) and Bpl wire are used.

Marking:

Marking of fencing parts is adopted in accordance with standard series

Manufacturing of reinforced concrete fence PO-2 (PO-3) meets the requirements series IZH 31-77"Parts of prefabricated reinforced concrete fences", reinforced concrete fence P-1 (P-5, P-6) corresponds series 3.017-1, Issue 1"Reinforced concrete elements of fences"

Prices for reinforced concrete fence and glasses

Reinforced concrete fences PO-2 fencing slabs for prefabricated reinforced concrete fences are used in many areas of construction. Industrial, industrial, civil and residential construction widely use high-strength fences as fencing for a wide variety of objects and surrounding areas. It is worth noting that in addition to concrete and reinforced concrete, building materials such as wood, metal or brick are also used as fences. The choice of one material or another depends on the purpose of the fences and climatic conditions in the area of ​​construction of the facility. However, as practice shows, wooden fences short-lived and easy to break, brick fences are not cheap, but metal fences are subject to corrosion.

Reinforced concrete, in turn, has significant advantages over other building materials. The high strength of concrete reinforced with high-strength steel allows reinforced concrete fences of PO-2 fencing slabs for prefabricated reinforced concrete fences to be subjected to constant significant loads. Reinforced concrete fences easily resist corrosion, climate change and sudden changes temperatures, from +35°C to -55°C. The high strength and water resistance of concrete make it possible to install fences directly into the ground. All these characteristics lead to the main advantage of the products - durability: fences and fencing elements made of reinforced concrete can last up to 50-70 years, or even more, while their original properties are maintained throughout their operation.

Another important advantage of reinforced concrete products is the relatively low price concrete raw materials, allowing you to save budget, not only for large companies, but also for people - during the construction of a private house and improvement of the adjacent land plot. Reinforced concrete products are also easy to install and do not require constant maintenance and treatment of external surfaces. Thus, we can conclude that the use of reinforced concrete in any area of ​​construction is beneficial in all respects: quality reinforced concrete products allow the construction of truly reliable structures, buildings and structures that will last quite a long time without requiring constant repairs.

Fences reinforced concrete slabs PO-2 fencing for prefabricated reinforced concrete fences are manufactured in full accordance with the instructions given in series 3.017-1 “Fencing sites and areas of enterprises, buildings and structures” issue 1 “Reinforced concrete elements of fences”, 3.017-3 “Fencing sites and areas of enterprises, buildings and structures", issue 1 "Reinforced concrete elements of fences", IZH 31-77 "Prefabricated reinforced concrete fences with a height of 1.2; 2 and 2.25 m" and AE-01-07 "Fencing areas industrial enterprises, warehouses and transport buildings and structures." Also, fencing elements of PO-2 fencing slabs for prefabricated reinforced concrete fences can be manufactured in accordance with technical specifications, which are developed individually at the manufacturer together with the design organization.

Reinforced concrete fence slabs PO-2 for prefabricated reinforced concrete fences are made of heavy concrete. Compressive strength class is accepted from B15 and above. The frost resistance class of concrete is assigned from F100 and higher, depending on the climatic conditions in the construction area. The water resistance class of concrete is assigned to at least W4. To provide additional protection fences from the destructive effects of moisture in concrete mixture Various air-entraining and water-repellent additives are added.

Reinforced concrete fences and fencing elements of PO-2 fencing slabs for prefabricated reinforced concrete fences are reinforced with meshes, which are assembled into three-dimensional frames using resistance spot welding. Hot-rolled steel of periodic profile is used as a material for reinforcing products. classes A-I, A-II, A-III and cold-drawn wire of class BP-I. For ease of installation, lifting loops are made of hot-rolled smooth reinforcing steel of the A-I brands Vs3ps2, embedded elements are made of rolled steel grade Vst3kp2 or S235.

The appearance of products and the quality of surfaces must meet the requirements of GOST 13015-67. Sinkholes with a diameter of more than 3-5 mm, and concrete swells of more than 3 mm are not allowed (concrete swells are strictly not allowed in the foundation shell). Cracks and exposure of reinforcement are strictly prohibited, since the products are exposed to outdoors and are influenced by the environment.
