Reinforced concrete racks SV - vibrated reinforced concrete products, reinforced with reinforcement. Representing poles of various sections, they are used in energy construction: when installing power transmission line supports, constructing or repairing supports for high-voltage lines 0.38-35 kV, and laying outdoor lighting networks. At the LLC Trest ZhBI company, vibrating racks are produced according to series 3.407.1-143, OKP/KUGN code 58 6311/16012.

The SV design is based on heavy concrete B 30, poured into the formwork on a vibrating table. Depending on the type of product, the racks are reinforced with prestressed rod and unstressed spiral reinforcement, and are equipped with grounding elements. As a grounding conductor, rod reinforcement is used, fixed inside the structure with outlets at the ends. Using the releases, subsequent grounding of the traverses is carried out.

Depending on the area of ​​application, different working drawings are involved in the production of reinforced concrete SV racks:

• series 3.407.1-143 for 10 kV overhead line support elements,
• No. LEP98.02 for racks operated in moderately aggressive environments,
• albums No. 14.0063, No. 7.0597, No. 11.0463, No. 25.7767 for structures that must withstand ice-wind and emergency loads,
• No. 9015 album 3 for supports used in extreme low temperature conditions.

Marking, storage and transportation of reinforced concrete supports SV

By marking you can determine the size and main performance characteristics products: the index “B” indicates the vibration technology used in production, the first numbers after the letters are the length in decimeters, and the numbers after the hyphen are the bending load-bearing capacity.

At the enterprise warehouse, the racks are stored in stacks up to 2.5 m high with the ends oriented on one side. In order not to damage the lifting loops, in the places where they are laid, the supports are placed with wooden spacers. Racks up to 16 m long can be transported by standard oversized trucks. SV 164 are transported in long lengths, and therefore transportation requires a permit for the transportation of oversized cargo.

Thousands of years have passed since the first known cases of using concrete until man figured out how to improve the properties concrete products reinforce them with steel reinforcement. The construction boom that began in most developed countries several decades after this event significantly expanded the scope of reinforced concrete and made it one of the most popular and most in-demand structural materials.

A similar breakthrough is reflected in the rapidly developing energy sector. Industrialization and electrification of any state required the creation of a huge number of power transmission lines from power generating stations to end consumers. Cable installation by installing wires in trenches dug in the ground requires considerable time and significant financial investments, and is justified only in certain cases. Therefore, overhead power lines are the most common, one of the key components of which is the SV 95-3 racks.

• Album 2. Supports with fastening brackets and traverses using bolts and clamps

In the section "GOSTs and SNiPs" you can download regulations on the SV pillars. The catalog presents all options for rack-mount products with a height of 9500 mm.

The production of energy racks is carried out only from heavy concrete, prepared taking into account the special operating characteristics. A long period of operation requires a dense structure of the material. Among the advantages of “energy” concrete are low permeability (W6-W8), high frost resistance F200, resistance to aggressive soil environments and cracking. Concrete pillar successfully passes tests for strength, rigidity, and crack resistance. Working drawings and design diagrams for overhead line racks according to GOST23613-79 secured Series Code 26.0085 . The reinforcement of the racks is carried out with prestressed reinforcing bars welded into spatial frames. The high class of steel gives the rack a huge margin of reliability - At-I, At-V, At-VI. The weight of the SV 95.3c-IV rack is 750 kg. Therefore, it is better to entrust the delivery of vibrating supports to professionals. Experienced Kompleks-S drivers will quickly ensure delivery of SV 95, SV 110 and other racks to the site or warehouse.

Under each horizontal row they are placed on wooden spacers. Reinforced concrete racks are stored on special platforms (horizontal, with a hard surface and the presence of drainage) in stacks 1.6-1.8 m high with wooden spacers installed between the rows.

Product quality control

All reinforced concrete products, working in bending or experiencing vertical loads, must be very carefully checked during the acceptance control procedure. No manufacturer's guarantees will save you if the racks have cracks more than 0.2 mm wide, exposed reinforcement, extensive traces of corrosion, chipped concrete and sinks in large quantities depth of more than 0.5 cm. The thickness of the protective layer of the SV 95-3s-IV rack reinforcement must correspond to the design one. All rack embedded parts must be in place and in accordance with the working drawings. Drawings and diagrams are provided by Series Code 26.0085. In addition, accompanying documents are subject to control, which must indicate: the number of racks, the grade of concrete for strength, frost resistance, water resistance, the presence of embedded products, the class of reinforcement.

The reinforced concrete rack SV 95-3s (vibrated) is the main (load-bearing) element of the support of overhead high-voltage power lines. Its main function is to hang electric wires at a distance corresponding to the standards to the objects underneath. The standards depend on the voltage in the lines: the higher it is, the longer support. Therefore, in every specific case it is necessary to increase the supports to required sizes reinforced concrete rod. The reinforced concrete support is made of heavy concrete reinforced with metal. All metal elements undergo a hot or cold galvanizing process to protect the metal from corrosion.
