Tower crane foundation and construction method thereof

Abstract

The invention discloses a tower crane foundation and a construction method thereof. The tower crane foundation comprises a concrete supporting plate, a steel structure foundation and a positioning frame, the positioning frame comprises a top frame and a plurality of vertically arranged pouring pipes, the upper ends of the pouring pipes are fixedly connected with the top frame, and a plurality of mortar outlet holes are formed in the side walls of the pouring pipes; a plurality of vertical positioning through holes are formed in the concrete supporting plate, the steel structure foundation is located on the upper surface of the concrete supporting plate, the pouring pipes penetrate through the positioning through holes, the steel structure foundation is compressed and fixed to the concretesupporting plate by the top frame; and a tower crane mounting structure is arranged on the upper surface of the steel structure foundation. The concrete foundation with the large size does not need tobe poured, the construction period can be shortened, and materials are saved; the concrete supporting plate, the steel structure foundation and the positioning frame can be rapidly connected and mounted, and the construction efficiency is improved; and after construction, the steel structure foundation, the concrete supporting plate and the like can be reused, and thus the engineering cost is saved advantageously.

Description

technical field [0001] The invention relates to the technical field of tower crane construction, in particular to a tower crane foundation and a construction method thereof. Background technique [0002] The common practice of tower crane foundation is cast-in-place concrete foundation, and there are also prefabricated assembled foundations. However, when the current method is used for construction, the volume of the poured concrete foundation is generally large, and the construction also needs to go through the binding of steel bars, formwork, embedded bolts and There are multiple processes such as pouring concrete. The construction period of the cast-in-place tower crane foundation is long. After the construction is completed, the tower crane foundation cannot be reused. After the tower crane is dismantled, the concrete foundation needs to be demolished by blasting or mechanical crushing. It is cumbersome and inconvenient to transport and install. Obviously, the two method...
