Abstract

The invention discloses a prestressing-force concrete tower structure and a construction method thereof. The structure comprises tower segments, and a group of the tower segments which are sequentially connected with one another in the vertical direction are arranged; the tower segments comprise lower connecting ring segments, middle ring segments, and upper ring segments from top to bottom; lowerportion pre-embedded members are arranged at the positions, close to the bottom faces, of the inner side faces of the lower connecting ring segments, and top connecting reinforced bars are reserved on the top faces of the lower connecting ring segments; upper portion pre-embedded members are arranged at the positions, close to the top faces, of the inner side faces of the upper connecting ring segments, and bottom connecting reinforced bars are reserved on the bottom faces of the upper connecting ring segments. According to the tower structure, the adjacent tower segments are connected through the lower portion pre-embedded members of the lower connecting ring segments above and the upper portion pre-embedded members of the upper connecting ring segments below, and the technical problemsof higher cost and longer construction period of a traditional prefabricated prestressing-force concrete tower structure are solved.

Description

technical field [0001] The invention relates to a prestressed concrete tower column structure and a construction method thereof. Background technique [0002] For the prefabricated prestressed concrete tower structure, due to the limitation of the prefabrication process and the prefabricated block rules of the tower structure, there are always various prefabricated errors between the prefabricated blocks. In order to successfully complete the assembly process, it is often necessary to set up various structural splicing seam. These splicing joints need to cast part of the concrete or part of the grout during the assembly construction process; however, the cast-in-place concrete requires a long curing time, and the cast-in-place grout will cost more, and the two construction processes Both require a certain amount of maintenance time, resulting in a longer construction period; in addition, the existing prefabricated tower columns are all internal and external formwork, and th...
