Specifications of pre-stressed beam of Iran pre-compressed concrete company

The prestressed beam produced by this company is made of ribbed wires with a resistance of 1475 to 1960 newtons per square millimeter and high quality concrete with a special mixing design of this company and with a resistance class of c35 and above and in a dry form (non-slump), which needs to be compacted Violent shaking is using. The production of this special concrete, whose granulation is constantly controlled, requires special batching, which is currently one of the few producers of this product, Iran's pre-compressed concrete company.

Prestressed beam execution method

First, the steel wires are placed on the band based on the type of pre-tensioned beam and are stretched by special jacks up to 65% of the final capacity. Then the machine is placed on the wires and concrete pouring with 450 grade and in dry form (noon slump) begins. After the concrete is set and the concrete is specially processed, which is under the cover, floor heating and steam technology, the sample cubes are broken by the equipped laboratory of this company and after getting the appropriate answer based on the company's factory standard, The release of the wires takes place and the force of the wires is applied to the cross-section of the beam, so the beam is pre-tensioned.

Weight per meter of prestressed beam

The weight of the prestressed beam produced by this company is between 23 and 25 kg, which reduces the volume of concreting the roof due to the fullness of the prestressed beam and ultimately reduces the overall weight of the building, of course, the weight of the truss, fandole and concrete heel beams. And.... taking into account the used rebars and filling them with concrete in Jariz, it will be more than this amount.

Iran's pre-compressed concrete company, with 50 years of brilliant history, is the first and largest factory producing standard pre-stressed beams up to the length of 12 meters and hollow slabs in the country. Daily 3000 meters of prestressed beam continues to shine as a leader in the country's prestressing industry.
