Supporting steel platform structure of large-cantilever high-altitude overrun cast-in-place beam plate and construction method
The invention relates to the technical field of constructional engineering, and discloses a supporting steel platform structure of a large-cantilever high-altitude over-limit cast-in-place beam slab and a construction method, and the supporting steel platform is a space steel structure cantilever platform formed by connecting and combining a plurality of single-layer supporting frames and a plurality of double-layer supporting frames. When the cantilever length of the upper cast-in-place beam slab is larger than 4.5 m or the concentrated load of the beam slab is larger than or equal to 20 kN/m, a double-layer supporting frame is arranged, otherwise, a single-layer supporting frame is arranged; the double-layer supporting frame comprises a main cantilever beam, a secondary cantilever beam, a first inclined strut, a second inclined strut, a third inclined strut, a fourth inclined strut, a fifth inclined strut and a sixth inclined strut, and the single-layer supporting frame comprises a main cantilever beam, a fifth inclined strut, a sixth inclined strut, a cantilever beam connecting beam and an inclined strut connecting beam. Formwork supporting loads are dispersed to the (N-1) th floor, the (N-2) th floor and the (N-3) th boundary beam, the platform deformation is small, the influence on a building main body structure is small, enough stability and bearing capacity are achieved, mounting and dismounting are convenient, the construction progress is fast, the engineering cost is low, and the construction problem of the large-cantilever high-altitude over-limit cast-in-place beam is effectively solved.
本发明涉及建筑工程技术领域，公开了大悬挑高空超限现浇梁板的支撑钢平台结构及建造方法，所述支撑钢平台为由若干单层支撑架和若干双层支撑架联排并结合构成的空间钢结构悬挑平台，上方现浇梁板悬挑长度＞4.5m或梁板集中荷载≥20kN/m时设置双层支撑架，否则设置单层支撑架；双层支撑架包括主悬挑梁、次悬挑梁、第一、第二、第三、第四、第五和第六斜撑，单层支撑架包括主悬挑梁、第五和第六斜撑，还设有挑梁连系梁和斜撑连系梁。本发明将支模荷载分散到第N‑1层、第N‑2层楼面及第N‑3层边梁上，平台变形小，对建筑主体结构影响小，具有足够稳定性及承载力，方便安装及拆除、施工进度快、工程成本低，有效解决了大悬挑高空超限现浇梁的施工难题。
