Abstract

The invention discloses a skewed prefabricated T-beam prestress tension construction method and an auxiliary device, and belongs to the technical field of building construction methods. The method comprises the following steps: the tension force required by a prestress tendon is calculated according to the existing condition of a T-beam; a working anchor is arranged on the tendon in a sleeving mode and fixed; a steel pipe is arranged on the tendon in a sleeving mode, meanwhile, a tool anchor is arranged on the side, away from the working anchor, of the steel pipe, and the tool anchor is arranged on the tendon in a sleeving mode; a jack is arranged on the steel pipe in a sleeving mode, and is in tight fit with the steel pipe; and the tension force of the jack is controlled according to the calculated required tension force, and the tension action is conducted. The steel pipe and the tool anchor are arranged, the tool anchor and the working anchor are matched to keep the steel pipe stable, then the jack is arranged on the steel pipe in the sleeving mode and is in tight fit with the steel pipe to conduct the tension action, and the method is easier and more convenient to implement; and meanwhile, as the situation that an anchor plate is installed after the jack is in butt joint with the working anchor is avoided, the jack is prevented from popping up accidentally, and thus the life safety of constructors is guaranteed.

Description

【Technical field】 [0001] The invention relates to a prestressed tensioning construction method and an auxiliary device of oblique prefabricated T beams, belonging to the technical field of building construction. 【Background technique】 [0002] For large-angle oblique prefabricated T-beams, the anchor plate is generally pre-buried in the building during the prestressed tensioning process. Because the anchor plate is pre-embedded, the jack cannot be directly attached to the anchor for prestressed tension work. The traditional method is to set the jack on the steel pipe, and use multiple anchor rings to superimpose in the jack, so as to extend the working space of the jack and carry out prestressed tensioning work. However, this method is relatively complicated, and during the stacking process of the anchor rings, pop-ups may occur, resulting in safety accidents. [0003] Therefore, it is necessary to improve the prior art to overcome the defects in the prior art. 【Content ...
