    Tie Rod Rock Bolt for Form Works in Dia. 15/17mm

    Product Introduction

    Tie Rods are high-strength, high-precision, straight-line steel bars with external threads on the entire steel bar. The steel bar can be screwed onto the connector with internal threads at any section or screwed with a threaded nut with internal threads for anchoring. The utility model has the advantages of simple connection and anchorage, strong adhesion, safe and reliable tension and anchorage and the like, and is a novel material for developing prestressed concrete component.

    Tie Rods are currently used to anchor and support the dam body form of the dam foundation. In the cable-stayed bridge, fully threaded bars are used as the main ribs and bridge foundations of the main tower. The use of fully threaded steel bars saves steel, reduces component area and reduces component weight.

    The continuous external thread is hot rolled. The shape of thread bar is shown as following figure. The main dimension ranges from ⌀15mm-⌀50mm and the grade ranges from 500/630Mpa to 1200/1330Mpa.
