Galvanized steel strand details

The strand is composed of a plurality of steel wire stranded, the surface of carbon steel can be increased according to the need of zinc coating, zinc layer, Aluminum Alloy Bao Lvceng (aluminum clad), epoxy resin coated copper layer (epoxy, coated).

Classification of galvanized steel strand

The most commonly used steel strand for galvanized steel strand and prestressed steel strand, commonly used prestressed steel strand diameter in the range of 9.53mm-17.8mm, with a small diameter steel wire. Each strand of prestressed steel strand in general is 7, there are also 2, 3 and 19, steel wire can be metal or non-metallic anti-corrosion layer. HDPE (unbonded steel strand), coated with anticorrosive grease or wax, which is called unbonded prestressed steel strand.

Galvanized steel strand

Galvanized steel wire usually used for bearing cable (Messenger, wire) (guy wire), cable (core wire or strength core member), can also be used as the ground wire of overhead transmission (earth wire/ground wire), the road on both sides of the arresting cable (barrier cable) structures of the cable (structure cable). The prestressed steel strand used in prestressed steel strand for the uncoated low relaxation prestressed steel strand (uncoated steel strand for prestressed concrete), has galvanized (Galvanized), commonly used in bridge construction, water conservancy, energy and geotechnical engineering, unbonded prestressing steel strand (unbonded steel strand or monostrand) commonly used in the slab and foundation engineering etc..

Technical analysis of galvanized steel strand

Steel strand prestressed tension construction design control tension, refers to the prestressing force after the completion of the steel strand in front of the anchor fixture. Therefore, in the calculation of prestressed steel strand tension elongation theory, should be between the steel strand anchorage point two distance as the length calculation of steel strand, but in the prestressing steel strand tension control is in control of the jack tool anchor, so the calculation convenient for control and, generally between steel two strand anchorage point distance, plus steel wire tension in the working length in the jack, the prestressed steel strand tension elongation length calculation theory. In the prestressed steel strand tension, the exposed parts of steel strand, most were surrounded by anchorage and Jack, tensioning elongation of steel wire can not be directly measured in the steel strand, the piston stroke can only be measured by Jack, the value of the tension calculation of steel strand, but also should be cut steel wire Zhang Laquan of anchorage rebound. The bearing capacity of the steel strand shall be 4-6 times of the total tractive force.

Features: high tensile strength, low relaxation and stable elastic modulus.
