Problems solved by technology

In the existing construction technology, if the length of the components exceeds a certain range, the structure cannot be completed in one go, and the steel strands will be segmented, and the segmented prestressed steel strands will be connected by extenders.
Although the structure of the prestressed extender is simple and easy to install, it is easy to cause quality problems such as anchorage failure

Abstract

The invention discloses a pre-stressed prefabricated fabricated structure and a penetrating and delivering steel strand composite device. The composite device comprises a steel strand, a threader, a conveyor shaft, a temporary self-locking device and floor fixing devices. The threader comprises a threading active shaft, a threading passive shaft, a gear, a steering knuckle, a bearing and a power device. The conveyor shaft is arranged between the threader and the bottom entrance of a column or a shear wall to change the penetrating and delivering direction of the steel strand and reduce the friction resistance at the turning point. The temporary self-locking device comprises a screw jack, a distribution beam and a working anchor. The floor fixing devices are located at the junction of eachfloor slab and the steel strand, and each floor surface structure is connected with the steel strand. According to the pre-stressed prefabricated fabricated structure and the penetrating and delivering steel strand composite device, the steel strand can be quickly and effectively delivered to a vertical forced component in a penetrating mode, the steel strand is continuously arranged along the whole height of the structure and connected with each floor surface structure, and a new way is opened up for popularizing the pre-stressed prefabricated fabricated structure.

Description

technical field [0001] The invention relates to the technical field of building structure engineering, in particular to a prestressed prefabricated assembled structure and a combination device for threading steel strands. Background technique [0002] With the development of engineering construction, super-long structures appear more and more in the construction field. However, in the existing construction technology, if the length of the component exceeds a certain range, the structure cannot be completed at one time, and the steel strands will be segmented, and the segmented prestressed steel strands will be connected by extenders. Although the prestressed extender is simple in structure and easy to install, it is easy to cause quality problems such as anchorage failure. In this prestressed prefabricated structure, the steel strands are arranged at the full height and fixed to each floor, without using extenders, avoiding hidden dangers and reducing costs.
