Problems solved by technology

Since the underframe is supported on the 4 outer corner ends of the ballast underframe beam 21, under the action of the upper load of the tower crane, especially when the installation height of the tower crane is high and the weight of the upper part is large, the ballast underframe beam 21 The deflection in the middle of the span is relatively large, which has a certain adverse effect on the structure of the tower crane

Abstract

The invention provides a universal five-point support loading type tower crane foundation and a construction method. The stress on a bottom frame, a bottom support rod and a bottom standard joint of the original tower crane is the same as the stress of the cast-in-place integral foundation. The universal five-point support loading type tower crane foundation comprises a bottom frame beam, a loading part and concrete support seats, wherein the bottom frame beam is in a cross shape, the concrete support seats are respectively arranged at the end parts and under the crossing part of the bottom frame beam, the upper parts of the concrete support seats are connected with a support plate through anchor bolts, the bottom plate is detachably connected with the bottom frame beam, the upper part of the bottom frame beam is connected with the bottom frame of the tower crane, the loading part is arranged above the bottom frame of the tower crane, and the loading part, the bottom frame of the tower crane and the bottom frame beam are detachably connected into a whole.

Description

technical field [0001] The invention relates to a tower crane for building construction, in particular to a general-purpose five-point support ballast type tower crane foundation and a construction method. Background technique: [0002] Tower cranes (hereinafter referred to as tower cranes) are indispensable construction equipment in building construction. In the construction of high-rise buildings, fixed-attached tower cranes are used. The foundation of the tower crane is an important part to ensure the safety and normal use of the tower crane. At present, the factory-configured foundations of common tower cranes generally include square foundations with small underframes without braces, cross-shaped foundations with large underframes with braces, and square foundations with small underframes without braces. figure 1 , figure 2 , image 3 , the big underframe has strut cross-shaped foundation see Figure 4 , Figure 5 , Figure 6 ; Because these two types of foundat...
