The process schematic diagram that the girder steel handling of bearing of internal climbing tower crane bottom changes to be the fixed girder steel in upper portion, its concrete step as follows:
the tower crane is converted from a normal fixed use state into an internal climbing jacking state to carry out internal climbing jacking, a middle fixed steel beam is converted into a lower bearing steel beam when jacking is finished, an upper fixed steel beam is converted into a middle fixed steel beam, and the tower crane is recovered to the normal fixed use state;
after the original lower part bearing steel beam frame is separated from the internal climbing tower crane, the original lower part bearing steel beam frame is disassembled one by using a hoist according to the sequence from top to bottom;
after disassembly, connecting a steel wire rope guide cable of a winch with the side ear plate of the steel beam, dragging the steel beam out of the core cylinder by combining a fixed pulley block which is temporarily installed, and dragging one end of the steel beam to the peripheral edge of the building structure;
and the tower crane hook is placed at the corresponding position of the steel beam conversion layer, the steel wire rope is hung on the steel beam ear plate, the whole steel beam is slowly dragged out by using the tower crane, and then the whole steel beam is hoisted to the specified position of the next tower crane fixed layer. The whole steel frame and steel beam structural steel is adopted for hoisting in sequence from bottom to top during hoisting;
and embedding corresponding embedded parts, and after the structure reaches a certain strength, mounting the steel beams in place one by using relative small hoisting equipment such as a hoist. Thereby completing the transferring and mounting of the steel beam.
The whole internal climbing tower crane steel beam transferring process is simple and efficient, easy to operate, less in input people, materials and machines, and a novel efficient steel beam transferring construction method.
While the present invention has been described in detail and with reference to the embodiments thereof as illustrated in the accompanying drawings, it will be apparent to one skilled in the art that various changes and modifications can be made therein. Therefore, certain details of the embodiments are not to be interpreted as limiting, and the scope of the invention is to be determined by the appended claims.
