TIAN GUIHONG / SHEN ZHANGCHENG / HU MINGLIANG / HE WENQIANG / PENG YAN

The invention relates to a tool-type section-steel cantilever unloading platform which comprises a section-steel cantilever beam detachable positioning fixture structure, a section-steel cantilever beam detachable coplanar combined entire anchoring structure, a section-steel cantilever unloading platform mounting and temporary fixing system, and a section-steel cantilever unloading platform loading test system, wherein the section-steel cantilever beam detachable positioning fixture structure comprises a cantilever main beam, a cantilever main beam sunken fixed sleeve fixing system, a cantilever main beam and reinforced concrete outer-wall connecting structure, and a cantilever main beam side surface fixing structure; and the section-steel cantilever beam detachable coplanar combined entire anchoring structure comprises a cantilever main beam detachable entire anchoring structure and a section-steel cantilever beam connecting structure. The tool-type section-steel cantilever unloadingplatform has the beneficial effects that detachable positioning fixtures are adopted, so that the heights of reserved holes required for the penetration of cantilever beams through an outer wall can be reduced and the degree of the influence on the structures can be reduced.

本发明涉及一种工具式型钢悬挑卸料平台，包括型钢悬挑梁可拆卸式定位固定件结构、型钢悬挑梁可拆卸同平面组合整体锚固结构、型钢悬挑卸料平台安装临时固定体系和型钢悬挑卸料平台加载试验系统；所述的型钢悬挑梁可拆卸式定位固定件结构，包括悬挑主梁、悬挑主梁下沉式固定套筒固定体系、悬挑主梁与钢筋混凝土外墙连接结构以及悬挑主梁侧面固定结构；所述的型钢悬挑梁可拆卸同平面组合整体锚固结构，包括悬挑主梁可拆卸式整体锚固结构以及型钢悬挑梁连接结构。本发明的有益效果是：本发明的型钢悬挑梁采用可拆卸式定位固定件，减小了挑梁穿外墙时所需预留洞的高度，降低了对结构的影响程度。
