brief information

Fencing (fence) slabs PO 2- iron data 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.

Reinforced concrete fencing slabs PO 2 are a high-strength product; due to their 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 the fence is made of reinforced concrete slabs is the simplest and most reliable way of fencing and protecting the territory. 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.

To produce a high-quality product, high-quality cement and sand are used, 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, a reinforced concrete fence is dismantled and transported to another place.

Marking

Symbol The 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.

Description

Product Description

Channel floor slab PO-2 slab is a rectangular reinforced concrete product used to cover channels, tunnels, and chambers made of tray products. The design of the plate contains one or two holes with a diameter of 70 cm for vertical entry into the channel. The dimensions of the product are selected strictly according to the width of a particular tray or chamber. The floor slab also helps maintain tightness and protect underground utility channels from destruction of insulation, soil collapses and moisture ingress.

Product marking

For an example of marking a floor slab, consider PO-2, where:

• PO - Channel slab with hole
• 2 - standard size of the product.

Product types

PO floor slabs are classified according to the following standard sizes:

• PO-1 - height 12 cm, length 110 cm, width 110 cm.
• PO-2 - height 14 cm, length 140 cm, width 110 cm.
• PO-3 - height 17 cm, length 170 cm, width 110 cm.
• PO-4 - height 22 cm, length 230 cm, width 110 cm.

Trays are popular reinforced concrete products, which cannot be avoided when laying thermal and drainage routes, as well as other utilities. They perform protective function. The PO-2 plate is a reliable element suitable for use in different types soil. It is able to withstand heavy loads for a long time due to its outstanding strength and resistance to aggressive environments. Its size (145 x 150 x 12 cm, which corresponds to current standards) and thoughtful design make it easy to transport and install.

Question answer

- Delivery cost?
Delivery is calculated based on the distance of your facility, from the warehouse, as well as the tonnage and dimensions of the products.

-Where are you bringing it from?
Delivery is carried out directly from production. Production facilities are located throughout the central region, and before entering our network, they undergo strict quality control by the legal, accounting and quality departments.

- Where is the post office?
For the convenience of users, we have created a system for distributing the load on managers; if 1 person checks mail, this significantly slows down the work or even leads to the fact that read letters are lost. You can leave a request through the form at the top of the site “Leave a request”, it will go to a free manager and they will call you back within 5 minutes.

- You have mobile number?
For the convenience of users, we have made a system for distributing the load on managers, if a mobile phone is specified, then only 1 person can talk on it, and it will be difficult to get through to him during the season.

- Why so expensive?
The price of a product consists of several components, the main of which is the cost of the material, which determines the quality of the final product. There is also a factory margin and a trading company margin, we work on the terms of a dealer discount, therefore we do not have a margin separate from the factory, we earn on the fact that the factory shares with us part of its profits, and we, in turn, provide the factory with volume to ensure uninterrupted operation .

- Why can’t you order less than 15 thousand? Do you work only in wholesale?
Some items are made in nearby areas and the delivery of these items adds a significant cost to the product. We have calculated that when ordering more than 15 thousand, the benefit from purchasing products from us becomes greater. If you have a small request for products that are manufactured in your area, it will be cheaper to purchase products at the nearest factories. Unfortunately we have this moment There is not a single plant in the Moscow region that has passed our quality control.

- Where can I pick it up?
The products are manufactured at different factories, the region and the city can tell you the manager, because the factory is different for each product.

- Why is delivery so expensive?
Delivery is calculated based on the distance of the object from the factory warehouse. The delivery cost is divided by the number of items based on the weight of the product; if you order 1 item, the entire delivery cost will fall on it, but if there are 10 items in the order, the delivery price will be equally distributed over these 10 items.

- Do you work with VAT?
Yes, the company Beton Project LLC works for OSNO and is a VAT payer. All prices on the website include VAT.

- Why is only the office listed on the website and not the plant?
We are a dealer of factories and operate at our office address. Because Our list contains a significant number of factories that have passed our inspection; it is not rational to post all the addresses of factories with products, which would complicate the search for the right factory. If you are interested in where this or that product can be exported, you can always check with the Manager or use our delivery.

- Do you have a warehouse in Moscow?
We do not have a warehouse in Moscow or the Moscow region, because... this will have a negative impact on the cost of the product because it will entail additional costs.

- What kind of plant? What is the name of?
The products are manufactured at different factories, you can always come to the factory and see for yourself the quality of our products. Also, if you have any doubts, you can pay for the products directly to the factory.

Floor slab for trays and channels with a hole ( PO 2 ) - a rectangular slab covering channels, tunnels, thermal chambers from tray elements in the place where there is a 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, the design of the plate contains one or two holes with a diameter of 700 mm. Floor slabs are placed on the trays and beams of the chambers, and then they are installed on the slab concrete rings, which make up the chamber shaft.

Also, the presence of a plate helps to maintain tightness and protect underground engineering communications channels from insulation destruction, 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 aboveground and underground channels, and laid under the sheets of 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 helps to transfer vertical temporary and long-term loads to the slab - heavy concrete B 25 (M200-300) and high-quality steel reinforcement classes A-I and A-III. Reinforcement of the floor slab PO 2 is carried out with welded meshes and frames made of bar 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 arranged with separate steel rods and meshes.

Release 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 plates are due to the fact that the trays are blocked by them both along and across, according to the schemes for overlapping the chambers and channel nodes.

Designed for use under scouring influences groundwater The plates are additionally protected from corrosion. For this purpose in concrete mixture special additives are added. Thanks to them, the plate 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 on the channel due to its weight, this excludes the subsequent sliding of the plate on the concrete.

Mounting of plates takes place using the method of loopless mounting 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 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.
• quantity 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.

Reinforced concrete fence slab ( PO-2 ) - durable and durable design, able to easily withstand long-term exposure to moisture and any aggressive environment. Concrete slab fences are a guarantee of safety and reliability

A solid concrete fence is the choice of professionals who strive to maximally secure the area adjacent to their objects. After all, solid concrete is a serious obstacle both physically and psychologically.

The fence wall made of slabs reaches a height of up to 2.9 m, and due to the ability to place additional fences (for example, barbed wire) on the top of the slab, such a fence becomes an almost insurmountable obstacle for intruders. Civil buildings and construction sites are usually fenced with reinforced concrete fences 1.2 and 2 meters high. This height allows neither people nor animals to enter the territory of the facility, and also reliably hides the space from prying eyes.

Solid fences of the PO.2 series are used, as a rule, on industrial enterprises to avoid theft and medical institutions to protect the peace of patients.

A fence made of slabs is also a kind of protection from wind, debris and extraneous sounds, so the use of reinforced concrete slabs is also justified in residential areas.

But despite this, concrete fences are still security structures, therefore, sensitive enterprises and specially protected facilities, warehouses cannot do without them - the height of the concrete fence slab there is 2.25 meters. Corresponding wickets and gates have been developed for reinforced concrete fences, but the versatility of the products allows the use of any other entrance structures.

Making slabs using vibration pressing or vibration casting from good cement and quality sand, make it possible to give durability to the slabs with high strength.

The slab is used in conjunction with a glass-type foundation (FO), which is buried in the ground, giving the slab greater stability. Foundations and slabs are available for use even on heaving and bulk soils, provided that a sand cushion is used under the base of the reinforced concrete fence. Anti-corrosion protection of fencing elements buried in the ground is necessary, despite the high strength of heavy concrete grades M200 used for the manufacture of slabs. The frost resistance of such concrete is at least 50 freeze-thaw cycles. This helps the concrete not to collapse long years, despite the unstoppable change of seasons. The water resistance of the slab is at least W4, allowing it to withstand prolonged exposure to moisture and soil connections.

To strengthen the fence slabs, they are reinforced with steel of class A-III and BP-I, welded into frames. Metal carcass, pre-processed anti-corrosion protection covers a solid layer of concrete. For ease of lifting and proper installation, the slabs are equipped with sling loops.

A wide range of fence slabs allows you to complete any object various areas construction. Design drawings and norms for the production of intake slabs are contained in the IZH 31-77 Series. . Issue 1 of this series involves the manufacture of PO-2 slabs 2500 mm long. The significant thickness of the slabs (150 mm) reliably protects the territory from various extraneous sounds, dust and mechanical damage. It is possible to install barbed wire on top of the slab and lighting fixtures for added security.

Concrete fences, as a rule, differ high quality concrete surface. In most cases, different grooves or patterns are applied to the slabs to distribute wind loads and make the gray concrete less boring. Sometimes the relief of fence slabs is deliberately made very voluminous in order to make it impossible to climb along it.

Such a fence cannot be moved without special equipment and the wind load, which the slab can easily withstand even in a windy area. Also on the shoulder of the plate is a concentrated load of 100 kgf / pm. To confirm the quality fence slabs each brand is tested by the manufacturer until complete destruction.

The large mass of the slab - 1420 kg - does not allow it to be moved by either wind, moisture or a person. 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.

Product marking

The symbol of a fence slab consists of a designation of the type of structure and its standard size.

As an example of marking, consider slab PO.2 (2500x 150x 3000 mm), where:

• P – fence slab;
• Number – standard size of the product;

Markings, as well as the date of manufacture of the product and its weight are applied to the end face of each product.

Product installation

In addition to slabs, prefabricated enclosing structures consist of glass foundations. Various design features of the slabs make it possible to connect them into a continuous fence wall. As a rule, fence slabs of the IZH 31-77 series have basement part and is connected to the pillars by welding connecting elements;

Product quality control

The fence, as an external enclosing structure, must meet high requirements appearance. On a surface concrete slab Sinkholes and concrete overhangs of more than 3 mm are unacceptable. Cracks more than 0.3 mm wide and any exposed reinforcement are considered defects. A large number of cracks and cavities lead to rapid crumbling of the structure, the formation of holes and blurring on the surface of the product, which significantly reduces the protective function.

Structures made from concrete fence slabs are usually distinguished by the quality and smoothness of the concrete surface. The smooth concrete surface allows the use of original design solutions when painting the slab, turning the fence into an addition to the style of the building.

On procedure batch acceptance slabs, the strength of concrete, the compliance of reinforcement products and mounting loops, the strength of welded joints, the accuracy of overall dimensions, the thickness of the protective layer of concrete to the reinforcement, the presence and width of possible cracks are checked.

Quality concrete surfaces and the compliance of the mounting loops is checked by inspecting each product. The quality of reinforced concrete fence slabs is certified by a technical passport accompanying each batch. It informs the consumer about the number of reinforced concrete products in the batch, the date of manufacture of the batch, the mass of the product, and also provides the release strength of the concrete and the grade of concrete for frost resistance and water resistance.

Transportation and storage

Fence slabs, like others reinforced concrete slabs, stored horizontally in stacks. It is important to avoid overloading in a stack of slabs, so you should not stack more than eight panels on top of each other. Wooden spacers are placed between the slabs strictly on the same vertical. It is also possible to store fence panels in vertical position, then the slabs can be laid in cassettes in any quantity.

During the installation of fence slabs, vertical supports are used to prevent the slabs from tipping over before the foundations are grouted and backfilled.
