Method for erecting high-rise concrete large cantilever structure type steel scaffold
The invention relates to the technical field of building construction, in particular to a high-rise concrete large cantilever structure profile steel scaffold erecting method which comprises the steps that expansion bolt sleeves are pre-buried on small cantilever structure frame beams of the N-2 layer and the N-1 layer; anchor bolt embedded parts are pre-embedded on the N-1 layers of small cantilever structure edge sealing secondary beams; connecting anchor bolts are pre-buried in the N layers of small cantilever structures; a first layer of inverted triangular supporting frame and a second layer of inverted triangular supporting frame are arranged between the N-2 layer of small cantilever structure and the N-1 layer of small cantilever structure and between the N-1 layer of small cantilever structure and the N layer of small cantilever structure; the N layers of small overhanging structures are provided with horizontal overhanging I-shaped steel, and inclined struts are arranged on the lower sides of the horizontal overhanging I-shaped steel; a support scaffold system is arranged on the horizontal overhanging I-shaped steel; by arranging two layers of supports including the inclined struts and the inverted triangular supporting frames, the stable supporting effect is guaranteed, the inclined struts play a role in supporting the front portion of the horizontal outwards-protruding I-shaped steel, the inverted triangular supporting frames play a role in supporting the rear portion of the horizontal outwards-protruding I-shaped steel, and the vertically-arranged double inverted triangular supporting frames play a role in dispersing force.
本发明涉及建筑施工技术领域，具体的说是一种高层混凝土大悬挑结构型钢脚手架搭设方法，步骤包括：在N‑2层、N‑1层小悬挑结构框架梁上预埋膨胀螺栓套筒；在N‑1层小悬挑结构封边次梁上预埋锚栓埋件；在N层小悬挑结构中预埋连接锚栓；在N‑2层与N‑1层小悬挑结构之间、N‑1层与N层小悬挑结构之间设置第一、第二层倒三角支撑架；在N层小悬挑结构上设水平外挑工字钢，水平外挑工字钢下侧设有斜撑；在水平外挑工字钢上设置支撑脚手架体系；本发明通过设置斜撑、倒三角支撑架两层支撑，保证支撑效果稳定，由斜撑对水平外挑工字钢的前部起到支撑作用，由倒三角支撑架对水平外挑工字钢的后部起到支撑作用，竖直设置的双倒三角支撑架起到力的分散作用。
