Abstract

The invention provides a two-half type engineering tensioning system with screw teeth. The two-half type engineering tensioning system comprises an upper part counterforce device composed of an upper tensioning nut, a jack, a tensioning arm brace and an upper tensioning shoulder pole beam, a lower part counterforce device composed of a lower tensioning shoulder pole beam and a lower tensioning nut, a tensioning rod connected onto the upper part counterforce device and the lower part counterforce device, and a hoop mounted on an adjusting sleeve; the upper tensioning shoulder pole beam and the lower tensioning shoulder pole beam are of a two-half type and can be fitted and separated; an anchoring hole is formed in the middle of each piece of the shoulder pole beam in horizontal and vertical directions in a penetrating manner; the anchoring holes are matched with a structure needing to be tensioned; the anchoring holes are provided with the screw teeth or have no screw teeth and are matched with half nuts mounted on the anchoring holes; and at a working state, a distance S between the upper part counterforce device and the lower part counterforce device mounted on a connecting rod-sleeve anchoring system with the screw teeth is reduced through the tensioning of the jack, so that the aim of tensioning is realized. The tensioning system provides an effective counterforce point for a tensioning manner of the connecting rod-sleeve anchoring system with the screw teeth and the problem that the system cannot tension and construct is solved.

Description

Technical field [0001] The invention relates to an engineering tensioning system, which is not only suitable for the tensioning of suspension bridge suspenders, but also applicable to all tensioning engineering systems that require their prestressed tendons or slings to be able to rotate, move and expand during construction. Background technique [0002] In recent years, with the continuous innovation of anchoring forms of prestressed structures, suspension bridge suspenders are stretched, and other tensile engineering systems that require prestressed tendons or slings to be able to rotate, move and expand in a wide range during the construction process. In, people designed a very novel and beautiful new anchoring method, which is different from the previous pressure-bearing anchoring. It is composed of connecting rods with threads at both ends and a sleeve with threads in the middle. The screw-threaded connecting rod-sleeve anchoring system uses the knob of the sleeve to achieve...
