Stand column type telecommunication tower prestress reinforcing structure and reinforcing method
The invention discloses a stand column type telecommunication tower prestress reinforcing structure and method, the stand column type telecommunication tower prestress reinforcing structure comprises an upper surrounding sleeve, a hydraulic jack and a lower surrounding sleeve, and the upper surrounding sleeve is composed of a plurality of upper surrounding sleeve prestress reinforcing columns and an upper surrounding sleeve steel ring capable of being opened in a half-and-half mode; the lower encircling sleeve is composed of a plurality of lower encircling sleeve prestress reinforcing columns, a bottom support and a lower encircling sleeve steel ring capable of being opened in a half-and-half mode; top stress is applied to the encircling sleeve through the jack, the load borne by the tower body can be completely or partially counteracted, and the bearing capacity of the tower body is improved; under the condition that an original tower body is not dismantled and an original building structure is not damaged, prestress can be transmitted to the original tower body through the encircling steel ring, and the encircling steel ring and the original tower body work cooperatively and bear loads at the upper end together, so that the follow-up bearing capacity is improved; the multiple pieces of prestress reinforcing profile steel arranged around the tower body are provided with independent pressure applying and releasing systems, the unbalance loading action point can return to the center line under cooperative work, and inclination of the tower body is reduced.
本发明公开了一种立柱式电信塔预应力加固结构以及加固方法，包括上围套、液压千斤顶和下围套，上围套由若干个上围套预应力加固柱、可对半打开的上部围套钢圈构成；下围套由若干个下围套预应力加固柱、底部支座、可对半打开的下部围套钢圈构成；本发明通过使用千斤顶对围套施加顶应力，能全部或部分抵消塔身所受荷载，实现塔身承载力的提高；本发明可在不拆除原塔身、不破坏原建筑结构的情况下，通过围套钢圈将预应力传至原塔身，并使两者协同作业、共同承担上端荷载，提高后续承载力；本发明沿塔身周围布置的多根预应力加固型钢拥有相互独立的加、卸压系统，协同工作下可使偏载作用点回到中心线上，减少塔身倾斜。
