Modifying overhang platform for existing frame structure and modification method of modifying overhang platform
The invention discloses a modifying overhang platform for an existing frame structure and a modification method of the modifying overhang platform. The platform comprises a plurality of layers of overhang floor slabs, a rigid pulling assembly and a prestress pulling assembly, wherein the overhang floor slabs are connected to the existing frame structure, and an upper frame columns are connected between every two adjacent overhang floor slabs; the rigid pulling assembly comprises a first lower column hoop arranged on the bottom upper frame column in a sleeving mode, a first upper column hoop arranged on a frame column of the existing frame structure in a sleeving mode, and an inclined pulling beam connected between the first upper column hoop and the first lower column hoop in a pulling mode; and the prestress pulling assembly comprises a second lower column hoop arranged on the middle upper frame column in a sleeving mode, a second upper column hoop arranged on the frame column in the existing frame structure in a sleeving mode and a prestress cable obliquely connected between the second upper column hoop and the second lower column hoop in a pulling mode, the first upper column hoop and the second upper column hoop are anchored in the frame column through a first anchoring assembly, and the first lower column hoop and the second lower column hoop are anchored in the upper frame columns through a second anchoring assembly. The problems that a traditional reconstruction project firstly perform disassembly and then building, the cost is high, and the construction period is long are solved.
本发明公开了一种既有框架结构的改造悬挑平台及其改造方法，该平台包括：多层悬挑楼板，连接于既有框架结构，相邻悬挑楼板之间连接有上框架柱；刚性拉结组件，包括套设于底层上框架柱的第一下柱箍、套设于既有框架结构的框架柱的第一上柱箍、以及拉结于第一上柱箍和第一下柱箍之间的斜向拉梁；预应力拉结组件，包括套设于中层上框架柱的第二下柱箍、套设于既有框架结构内的框架柱的第二上柱箍、以及斜向拉结于第二上柱箍和第二下柱箍之间的预应力索，第一上柱箍、第二上柱箍分别通过第一锚固组件锚固于框架柱中，第一下柱箍、第二下柱箍分别通过第二锚固组件锚固于上框架柱中。本发明解决了传统改造项目先拆后建，成本高且施工工期长的问题。
