Large-span cantilever concrete beam plate supporting structure and construction method
The invention relates to the technical field of constructional engineering, and discloses a large-span cantilever concrete beam and slab supporting structure and a construction method in order to solve the technical problems that on-site construction technology is complex and construction period is long under the condition that safety is guaranteed. First overhanging I-shaped steel serving as a main beam is anchored in the steel bar pressing ring, and second overhanging I-shaped steel serving as a secondary beam is welded between the first overhanging I-shaped steel; the first cantilever I-shaped steel is divided into an anchoring section and a cantilever section, the length of the anchoring section is defined as a, the length of the cantilever section is defined as b, and a is larger than or equal to 1.25 b; overhanging supporting frames are arranged on the roof layer, the first overhanging I-shaped steel and the second overhanging I-shaped steel, a plurality of adjustable jacking supports are arranged on the upper portions of the overhanging supporting frames, and the adjustable jacking supports are arranged at different heights to form a supporting structure used for overhanging the concrete beam slab. The method has the advantages of saving cost and accelerating construction progress, and solves the technical problems of complex on-site construction process and long construction period under the condition of ensuring safety.
本发明涉及建筑工程技术领域，为了实现在保证安全下情形解决现场施工工艺复杂与工期长的技术问题，本发明公开了一种大跨度悬挑混凝土梁板支撑结构及施工方法，包括预埋的钢筋压环，钢筋压环内锚固有用作主梁的第一悬挑工字钢，第一悬挑工字钢之间焊接有用作次梁的第二悬挑工字钢；第一悬挑工字钢分为锚固段和悬挑段，定义锚固段长度为a，悬挑段长度为b，则a≥1.25b；屋面层、第一悬挑工字钢和第二悬挑工字钢上设置有悬挑支撑架，悬挑支撑架的上部设置有若干可调顶托，可调顶托通过设置不同高度形成用于悬挑混凝土梁板的支撑结构。具有节约成本和于加快施工进度的优点，在保证安全下情形解决现场施工工艺复杂与工期长的技术问题。
