Fabricated prestressed beam plate type fan foundation and construction method
The invention provides an assembly type prestressed beam plate type fan foundation and a construction method, and the fan foundation comprises a prefabricated fan-shaped ribbed beam bottom plate, a prefabricated fan-shaped ribbed beam bottom plate stand, a U-shaped connecting piece and a steel strand; the prefabricated fan-shaped ribbed beam bottom plate and the prefabricated fan-shaped ribbed beam bottom plate columns are each provided with a plurality of grooves, a U-shaped connecting piece is embedded in each groove, a plurality of reserved hole channels are formed in the prefabricated fan-shaped ribbed beam bottom plate columns, and the prefabricated fan-shaped ribbed beam bottom plate columns are connected and anchored through the reserved hole channels and steel strands. According to the method, prestressed anchoring is conducted on the annular holes reserved between the prefabricated stand columns through the post-tensioning method, the construction time can be greatly shortened, resource consumption is reduced, and the labor cost and the construction cost are reduced.
本发明提供了一种装配式预应力梁板式风机基础及施工方法，所述的风机基础，包括：预制扇形带肋梁底板、预制扇形带肋梁底板台柱、U形连接件和钢绞线；所述预制扇形带肋梁底板与预制扇形带肋梁底板台柱上分别开有多处凹槽，每个凹槽内均预埋U型连接件，预制扇形带肋梁底板台柱内设有多处预留孔道，预制扇形带肋梁底板台柱之间利用预留孔道采用钢绞线连接锚固；本发明通过对预制台柱与预制台柱之间预留的环形孔洞采用后张法进行预应力锚固，能够大幅缩短施工时间，减小了资源消耗，降低了人力成本和施工成本。
