Specifications of Iran Prestressed Joist

The prestressed joist produced by this company uses ribbed wires with a strength of 1475 to 1960 Newton per square millimeter and high-quality concrete with a special mixing design of this company, with a strength class of C35 and above, and in dry form (non-slump), which requires intense vibration for compaction. The production of this special concrete, whose grading is constantly controlled, requires a special batching plant, and currently, one of the few producers of this product is Iran Prestressed Concrete Company.

Method of Installing Prestressed Joist

First, steel wires are placed on the band according to the joist type classification and stretched by special jacks up to 65% of the final capacity. Then the device is placed on the wires, and concrete pouring with a mix ratio of 450 and in dry form (non-slump) begins. After the concrete sets and undergoes special curing, which includes placing under cover, underfloor heating, and steam technology, sample cubes are broken by the company's equipped laboratory. After obtaining suitable results according to the company's factory standard, the wires are released, and the wire force is transferred to the joist section, thus the joist is prestressed.

Weight per Meter of Prestressed Joist

The weight of the prestressed joist produced by this company is between 23 to 25 kilograms, which reduces the volume of concrete pouring in the ceiling due to the filled web of the prestressed joist and ultimately reduces the total weight of the building. Of course, the weight of truss joists, pendulum joists, concrete heel joists, etc., considering the used rebars and filling their webs with concrete in the joint, will be more than this amount.
