TANG HONGBING / HUANG SHIBIN / HUANG XUEYU / CHANG XIAO

The invention relates to a tower crane foundation, in particular to a construction method for mounting a tower crane foundation on a finished concrete structure. Comprising the following steps: step A, foundation design; b, corbels and connecting steel plates are manufactured and machined; c, drilling of the concrete structure is completed; d, connecting steel plates are attached to the two sides of the finished concrete structure correspondingly, and the connecting steel plates on the two sides are connected through bolts; e, brackets are welded to the connecting steel plates on the inner side of the concrete structure; f, the foundation beam is installed on the bracket; and G, welding seam detection. The holes are formed in the finished concrete structure, the steel plates are arranged on the two sides of the finished concrete structure, the bolts penetrate through the holes to mount the connecting steel plates on the finished concrete structure, the load of the tower crane is transmitted to the finished concrete structure, the tower crane is stably mounted, and the safety is improved.

本发明涉及塔吊基础，特别是一种已完混凝土结构上进行塔吊基础安装的施工方法。包括如下步骤：步骤A、基础设计；步骤B、牛腿、连接钢板制作加工；步骤C、已完混凝土结构钻孔；步骤D、已完混凝土结构的两侧分别贴设连接钢板，两侧的连接钢板通过螺栓连接；步骤E、已完混凝土结构内侧的连接钢板焊接牛腿；步骤F、将基础梁安装到牛腿上；步骤G、焊缝检测。本发明在已完混凝土结构上开孔，已完混凝土结构两侧设置钢板，并通过螺栓穿过开孔处将连接钢板安装在已完混凝土结构上，将塔吊的负荷传至已完混凝土结构上，塔吊安装稳固，提高安全性。
