Girder embracing type tower crane foundation steel bearing table and construction method thereof

Abstract

The invention relates to a girder embracing type tower crane foundation steel bearing table and a construction method thereof. The steel bearing table comprises girder embracing structures and a foundation steel bearing table body, wherein the girder embracing structures are mounted on frame girders of an existing structure and are close to a girder-column joint of the frame girders and a frame column; the girder embracing structures penetrate through the portions, on the two sides of the frame girders, of a floor slab and are clamped and fixed to the frame girders; mounting surfaces are formed on the girder embracing structures and located on the tops of the frame girders; and the foundation steel bearing table body is fixedly mounted on the mounting surfaces. The girder embracing structures are mounted on the frame girders, the foundation steel bearing table body is borne through the girder embracing structures, the girder embracing structures and the frame girders are embraced together to form a whole sable stress body, the anti-pulling effect of the connection positions of the foundation steel bearing table body and the girder embracing structures can be improved, the girder embracing structures and the frame girders form the whole stress body, the overturning force of a tower crane can be effectively resisted, the supporting stability of the foundation steel bearing table body is guaranteed, and the using safety of the tower crane is ensured.

Description

technical field [0001] The invention relates to the construction field of tower crane foundation caps, in particular to a beam-holding type tower crane foundation steel cap and a construction method thereof. Background technique [0002] Tower crane is the most commonly used lifting equipment in construction engineering. In order to ensure the safety of the tower crane, when installing the tower crane on the construction site, the foundation cap of the tower crane with a concrete structure is usually used. Specifically, four foundation piles are first driven into the installation position of the tower crane, and then lattice columns are inserted in the foundation piles, and then the concrete caps are constructed on the lattice columns, and the tower crane is installed on the concrete caps for Hoisting work. After the tower crane construction is completed, it is necessary to remove the concrete cap, the lattice column and some foundation piles, resulting in waste of material...
