Problems solved by technology

Among them, the broken stirrups still need to be welded at high altitude during the installation of the split steel bars, and due to the irregular shape of the split steel bars, it is difficult to control the hoisting center of gravity and the lifting posture in the air, and the installation alignment is difficult, resulting in low construction efficiency ; and the overall hoisting method of steel bar segments, the lifting weight of the steel bar segments is heavy, the tonnage requirement of the tower crane is high, and the construction cost is high

Abstract

According to the variable-cross-section large-cross-section pier tower reinforcement cage segment ring splitting structure, a high tower is divided into a plurality of pier tower segments, and each pier tower segment comprises annular reinforcement cage modules which are sleeved with one another. By the adoption of the technical scheme, the construction efficiency of the reinforcement cage segments is improved, and the purpose of saving construction cost is achieved.

Description

【Technical field】 [0001] The invention relates to the technical field of building construction, in particular to a section-ring split structure of a variable-section large-section pier tower steel cage segment. 【Background technique】 [0002] Concrete tower construction is usually divided into 4.5m or 6m sections and constructed section by section. The construction content of a single segment includes steel bar installation and concrete pouring construction, and the installation of steel bars for high towers accounts for about 2 / 3 of the tower segment construction time. For large-section and high-rise concrete structures, the steel bars are usually composed of multi-layer main bars, stirrup bars, hook bars, and U-shaped bars. The weight of the entire segmental bar is heavy, and the bar is a three-dimensional spatially continuously changing structure. [0003] The traditional installation of steel bars in high towers requires high-altitude operations, high wind speed, and di...
