设于既有混凝土结构上的塔吊系统及其施工方法
摘要：
本发明涉及一种设于既有混凝土结构上的塔吊系统及其施工方法，所述既有混凝土结构包括混凝土柱和连接于混凝土柱之间且平行设置的两个混凝土梁，所述塔吊系统包括：塔吊基础，包括至少两对倾斜地支撑于所述混凝土柱与所述混凝土梁的斜撑和至少一对连接于所述混凝土梁之间的支撑梁，所述斜撑的顶部固定于所述混凝土梁的下表面，底部连接于所述混凝土柱的底部，所述支撑梁平行设置，且端部与所述斜撑的端部对应设置；以及设于所述塔吊基础之上的塔吊。本发明采用在既有的混凝土结构上施工塔吊基础和附着，从而在未预留塔吊设置的位置时，也可以设置塔吊基础和附着并安装塔吊进行吊装，同时满足塔吊的受力要求。
摘要（英）：

The invention relates to a tower crane system arranged on an existing concrete structure and a construction method thereof. The existing concrete structure comprises concrete columns and two concretebeams connected between the concrete columns and parallelly arranged. The tower crane system comprises a tower crane foundation and a tower crane. The tower foundation comprises at least two pairs ofoblique supports obliquely supported on the concrete columns and the concrete beams and at least one pair of supporting beams connected between the concrete beams. The tops of the oblique supports arefixed to the lower surfaces of the concrete beams, the bottoms of the oblique supports are connected to the bottoms of the concrete columns, and the supporting beams are parallelly arranged. The endsof the supporting beams are arranged corresponding to the ends of the oblique supports. The tower crane is arranged on the tower crane foundation. The tower crane foundation and auxiliary parts are constructed on the existing concrete structure so that when the position for tower crane arrangement is not reserved, the tower crane foundation and the auxiliary parts can also be arranged, and the tower crane is mounted for hoisting; and meanwhile the stress requirement of the tower crane is met.
