Zipper occlusion type prefabricated cable bent tower and construction method thereof
The invention provides a prefabricated cable bent tower connected in a zipper meshing mode and a construction method thereof, the cable bent tower is vertically divided into a plurality of sections, the lowermost section is a tower body base and is of a reinforced concrete cast-in-place structure, and the other sections are prefabricated sections; each prefabricated section is annularly and equally divided into at least four reinforced concrete prefabricated blocks, the two ends of each prefabricated block are each provided with at least two inserting connectors, inserting openings matched with the inserting connectors are formed between the adjacent inserting connectors, the prefabricated blocks of each prefabricated section are in butt joint through the inserting connectors and the inserting openings, and steel bars are planted after the inserting connectors and the inserting openings are inserted in a penetrating mode; the main reinforcements of the upper section and the lower section are connected through a threaded sleeve, and the upper section and the lower section are connected through wet joint concrete. According to the method, the cast-in-place construction amount can be greatly reduced, and the construction efficiency is greatly improved; the anti-seismic effect of the tower body is not different from that of a cast-in And the tower body longitudinally forms a zipper occlusion effect, so that the connection strength between the precast blocks is ensured, and the appearance aesthetic feeling of the cable bent tower is improved.
本发明提供一种拉链咬合式连接的预制装配索塔及其施工方法，所述索塔竖向分为多个节段，其中最下层节段为塔身基座，采用钢筋混凝土现浇结构，其余节段为预制节段；每个预制节段环向等分为至少4个钢筋混凝土预制块，每个预制块的两端分别设有至少2个插接头，相邻插接头间设有与插接头匹配的插接口，每个预制节段的各预制块间通过插接头和插接口对接并穿插后植筋，上下节段的主筋间通过螺纹套筒连接，上下节段间采用湿接缝混凝土连接。本发明可大大减少了现浇施工量，大幅提高施工效率；塔身抗震效果与现浇方式无差异；塔身纵向形成拉链咬合式效果，既保证了预制块间的连接强度，又提高了索塔外观美感。
