Technical Field

The invention relates to the technical field of building construction, in particular to an F-shaped positioning piece for preventing a prestressed corrugated pipe from floating upwards and shifting.

Background

In the building pouring construction process, a reinforcement cage is bound in advance, a pouring template is arranged, and finally pouring forming is carried out. Generally, in order to improve the strength inside a casting, a plurality of high-strength steel tendons are arranged inside a steel reinforcement cage and are fixed by sleeving prestressed corrugated pipes. Because the poured concrete has extremely strong viscosity, the prestressed corrugated pipe is extruded and receives upward thrust in the pouring process, and if the prestressed corrugated pipe is not well fixed, the prestressed corrugated pipe floats upwards in the pouring process, so that the position of the reinforcing steel bar bundle is changed, and the strength increase caused by the reinforcing steel bar bundle is reduced.

The existing corresponding method is that after the construction of the steel reinforcement cage is finished and the prestressed corrugated pipe is arranged, the prestressed corrugated pipe and the steel reinforcement cage are bound and fixed. The method needs to be carried out before the template is erected, and workers need to climb to different heights along with the trend of the prestressed corrugated pipe and bind the positions needing to be fixed one by one, so that the efficiency is very low. The method has the defects that operation cannot be carried out after the template is erected, so if the binding stability is found to be not up to the standard in the pouring process, remedy cannot be carried out, and great uncertainty exists.

Therefore, the existing prestressed corrugated pipe setting mode in the building pouring construction still has a part to be improved urgently, the fixing efficiency of the prestressed corrugated pipe needs to be improved, and meanwhile, the stable reliability of binding can be ensured; the banding work should not be affected by the template setting, and the banding should be possible and remedied after the template setting. Therefore, a more reasonable technical scheme needs to be provided, and the defects in the prior art are overcome.
